Description

制動裝置以及使用該制動裝置的遮蔽裝置 Braking device and shielding device using the braking device

本發明係有關於制動裝置以及使用該制動裝置的遮蔽裝置，尤其有關於為了適當地減速昇降繩的移動而能夠使用之制動裝置。 The present invention relates to a braking device and a shielding device using the braking device, and more particularly to a braking device that can be used in order to appropriately slow down the movement of the lifting rope.

不僅捲簾和百葉窗，如折疊簾(accordion curtain)、折疊式紗窗(pleated net)及隔板等被半自動化的懸掛支撐式遮蔽裝置也正被應用。例如，當使橫式百葉窗呈打開狀態時，透過拉拽操作用繩，從而作為遮蔽部件的葉片和下樑被吊起。另外，當使橫式百葉窗呈閉合狀態時，一般利用葉片和下樑的自重而藉由重力使該等葉片和下樑降下。此時，眾所周知存在一種對伴隨著葉片和下樑的下降而移動之昇降繩施加制動力從而降低葉片和下樑下降的勢力之結構。 Not only roller blinds and blinds, such as accordion curtains, pleated nets, and partitions, which are semi-automatic suspension-supported shading devices are also being used. For example, when the horizontal blind is opened, the blade and the lower beam as the shielding member are hoisted by pulling the operation cord. In addition, when the horizontal blinds are closed, the weight of the blades and the lower beam is generally used to lower the blades and the lower beam by gravity. At this time, it is known that there is a structure that applies a braking force to the lifting rope that moves along with the descending of the blades and the lower beam, thereby reducing the force of the blade and the lower beam to descend.

專利文獻1中揭露了一種具備阻尼器之百葉窗的昇降裝置，其特徵在於，該阻尼器由產生制動力的離心式調速器和連結於制動器部的軸(夾持繩的夾持體)構成，昇降繩與該軸的外周面接觸，透過昇降繩的移動，該軸進行旋轉從而該制動器部進行動作。透過使用該阻尼器，能夠可靠地對伴隨著自重下降的昇降繩之移動賦予阻力。 Patent Document 1 discloses an elevating device for shutters with a damper, which is characterized in that the damper is composed of a centrifugal governor that generates a braking force and a shaft (holding body that holds the rope) connected to the brake section. , The lifting rope is in contact with the outer peripheral surface of the shaft, and through the movement of the lifting rope, the shaft rotates and the stopper part operates. By using this damper, it is possible to reliably provide resistance to the movement of the lifting rope accompanying the drop in its own weight.

專利文獻1：日本公報、特開2005-030084號 Patent Document 1: Japanese Publication, JP 2005-030084

但是，在專利文獻1所揭露之阻尼器中，在由於與昇降繩的摩擦而夾持體發生磨損從而夾持體直徑變小之情形下、或昇降繩直徑變細之情形下，無法恰當地對繩子賦予阻力。 However, in the damper disclosed in Patent Document 1, in the case where the holder body is worn due to friction with the lifting rope and the diameter of the holding body is reduced, or the diameter of the lifting rope is reduced, it cannot be appropriately Give resistance to the rope.

本發明係鑒於上述情況而完成者，提供一種即使在夾持繩子的夾持體因磨損而直徑變小之情形下或昇降繩直徑變細之情形下也能夠適當地夾持繩子之制動裝置。 The present invention has been completed in view of the above circumstances, and provides a brake device capable of holding the rope appropriately even when the diameter of the holding body for holding the rope is reduced due to wear or the diameter of the lifting rope is reduced.

The braking device has a clamping body provided with a pair of clamping members for clamping the rope. At least one of them is configured to move along a predetermined movement trajectory, the gripping body grips the rope at a predetermined gripping position of the movement trajectory, and the movement trajectory extends beyond the gripping position.

依本發明，構成為透過夾持部件的至少一方以規定的移動軌跡進行移動，從而能夠在規定的夾持位置夾持所述繩，並且，移動軌跡係超過夾持位置而延伸。利用該構成，在夾持體磨損前於規定的夾持位置夾持繩，在夾持體磨損後，透過夾持體移動至超過規定夾持位置而延伸的移動軌跡上的範圍，從而即使在夾持體磨損後也能夠適當地夾持繩，維持制動性能。另外，即使在繩直徑因繩的磨損而變細之情形下，也能夠發揮同樣的效果。 According to the present invention, at least one of the clamping members is configured to move along a predetermined movement trajectory, so that the rope can be clamped at a predetermined clamping position, and the movement trajectory extends beyond the clamping position. With this configuration, the rope is clamped at a predetermined clamping position before the clamping body is worn, and after the clamping body is worn, the clamping body moves to a range on the movement trajectory extending beyond the specified clamping position, even when the clamping body is worn out. Even after the clamping body is worn, the rope can be properly clamped to maintain the braking performance. In addition, the same effect can be exerted even when the diameter of the rope becomes thin due to the abrasion of the rope.

1.第一實施方式 1. The first embodiment

1-1<整體構成> 1-1 <Overall composition>

在圖1所示之遮蔽裝置100A中，多層日射遮蔽部件101經由多根方向控制繩123而懸掛支撐在中空的上樑130上，在上述方向控制繩123的下端懸掛支撐有下樑122。上樑130由頂面131、底面132及側面133構成。而且，在上樑130的兩端設 置有箱蓋(box cap)134。另外，在上樑130的內部設置有用於將繩CD插通於操作棒108內的繩出口135。方向控制繩123只要是能夠支撐及轉動日射遮蔽部件101之部件，則其構成便無限定，例如，亦可構成為：具備相互分離的兩根縱繩，其中一根縱繩安裝在葉片的一側邊緣上，另一根縱繩安裝在葉片的另一側邊緣上。 In the shielding device 100A shown in FIG. 1, the multi-layer solar shielding member 101 is suspended and supported on a hollow upper beam 130 via a plurality of direction control ropes 123, and a lower beam 122 is suspended and supported at the lower end of the direction control rope 123. The upper beam 130 is composed of a top surface 131, a bottom surface 132 and a side surface 133. Moreover, at both ends of the upper beam 130, A box cap 134 is provided. In addition, a cord outlet 135 for inserting the cord CD into the operating rod 108 is provided inside the upper beam 130. The directional control rope 123 is not limited as long as it is a member capable of supporting and rotating the solar shielding member 101. For example, it may be configured to include two longitudinal ropes separated from each other, one of which is mounted on one of the blades. On the side edge, another longitudinal rope is installed on the other side edge of the blade.

上樑130內配設有多個支撐部件(未圖示)，在該支撐部件上以能夠旋轉之方式支撐有傾斜滾筒(未圖示)。方向控制繩123的上端部安裝在傾斜滾筒上，所有的傾斜滾筒在其傾斜滾筒的中心部嵌插有軸124(軸部件)。因此，當軸124旋轉時，所有的傾斜滾筒被旋轉，伴隨著傾斜滾筒的旋轉，方向控制繩123的縱繩的一根被提拉，藉此，各日射遮蔽部件101和下樑122被以同相位進行角度調節。 A plurality of support members (not shown) are arranged in the upper beam 130, and a tilt roller (not shown) is rotatably supported on the support members. The upper end of the direction control rope 123 is installed on the inclined roller, and all the inclined rollers have a shaft 124 (shaft member) inserted in the center of the inclined roller. Therefore, when the shaft 124 rotates, all the inclined drums are rotated, and along with the rotation of the inclined drum, one of the longitudinal ropes of the direction control rope 123 is pulled up, whereby each solar radiation shielding member 101 and the lower beam 122 are Adjust the angle in the same phase.

上樑130的一端部上懸掛支撐有由筒體構成的操作棒108，操作棒108的下端上設置有操作部120。當把持操作部120對操作棒108進行旋轉操作時，經由配置在上樑130內的齒輪機構而使角度調節軸旋轉。因此，利用操作棒108的旋轉操作，能夠對各日射遮蔽部件101進行角度調節。 An operating rod 108 composed of a cylindrical body is suspended and supported on one end of the upper beam 130, and an operating portion 120 is provided on the lower end of the operating rod 108. When the gripping operation portion 120 rotates the operation rod 108, the angle adjustment shaft is rotated via a gear mechanism arranged in the upper beam 130. Therefore, it is possible to adjust the angle of each solar radiation shielding member 101 by the rotation operation of the operating rod 108.

從上樑130懸掛有多根(本實施方式中為三根)昇降繩102l、102c、102r(不需要區分之情形下僅稱為“昇降繩102”)，各昇降繩102的一端安裝在下樑122上。轉向滑輪(未圖示)以圖面的表裡方向的軸芯被可旋轉地支撐(軸支撐)在各支撐部件上，被導入上樑130的昇降繩102能夠沿上樑的左右方向引導轉向。另外，各支撐部件具有能夠使其他昇降繩沿左右方向通過的空間。因此，右端的昇降繩102r的另一端利用支撐部件被引導轉向，非操作側的昇降繩(左端和中央的昇降繩102l、102c)經過各支撐部件在上樑130內被向操作棒108的方向引導。接著，經過設置於上樑130內的鎖定部104和制動裝置100，***通在筒狀的操作棒108內，並且其前端與設置在操作部120下方的繩平衡器121連接。因此， 當向下方拉拽繩平衡器121而將昇降繩102從上樑130拉出時，透過提拉下樑122，從而拽起日射遮蔽部件101。 A plurality of (three in this embodiment) lifting ropes 102l, 102c, 102r are suspended from the upper beam 130 (only referred to as "lifting rope 102" if no distinction is required), and one end of each lifting rope 102 is installed on the lower beam 122 on. The steering pulley (not shown) is rotatably supported (shaft supported) on each support member with a shaft core in the front and back directions of the figure. The lifting rope 102 guided into the upper beam 130 can guide the steering in the left and right direction of the upper beam. . In addition, each support member has a space that allows other lifting ropes to pass in the left-right direction. Therefore, the other end of the lifting rope 102r at the right end is guided and turned by the supporting member, and the lifting ropes on the non-operating side (the lifting ropes 102l and 102c at the left and center) are guided in the direction of the operating rod 108 in the upper beam 130 through the supporting members. guide. Next, it passes through the locking portion 104 and the braking device 100 provided in the upper beam 130, is inserted into the cylindrical operating rod 108, and its tip is connected to the rope balancer 121 provided below the operating portion 120. therefore, When the rope balancer 121 is pulled downward and the lifting rope 102 is pulled out from the upper beam 130, the lower beam 122 is lifted to pull up the solar radiation shielding member 101.

鎖定部104根據繩CD(參照圖4)的動作，許可或限制繩CD的移動。 The lock unit 104 permits or restricts the movement of the cord CD in accordance with the movement of the cord CD (refer to FIG. 4).

制動裝置1000是對繩CD的移動進行制動之裝置。另外，對於制動裝置1000的構成和動作，之後進行敘述。制動裝置1000配置在上樑130的底面132上，且其兩端藉由側面133而被定位。另外，亦可代替在底面132上配置制動裝置1000，而在底面132上所設置的其他部件上配置制動裝置1000。 The braking device 1000 is a device for braking the movement of the rope CD. In addition, the structure and operation of the brake device 1000 will be described later. The braking device 1000 is disposed on the bottom surface 132 of the upper beam 130, and its two ends are positioned by the side surfaces 133. In addition, instead of disposing the braking device 1000 on the bottom surface 132, the braking device 1000 may be disposed on another member provided on the bottom surface 132.

制動裝置1000在上樑130內以圖4所示的前方朝向鎖定部104側、後方朝向繩出口135側之方式配置。因此，在日射遮蔽部件101完全下降的狀態下、亦即遮蔽裝置100A的閉合狀態下，當向下方拉拽一組繩CD時，繩CD被拉至圖4所示的後方。 The brake device 1000 is arranged in the upper beam 130 such that the front side is toward the lock portion 104 side, and the rear side is toward the rope outlet 135 side as shown in FIG. 4. Therefore, in a state where the solar radiation shielding member 101 is completely lowered, that is, in a closed state of the shielding device 100A, when the set of cords CD is pulled downward, the cords CD are pulled to the rear as shown in FIG. 4.

另一方面，在日射遮蔽部件101未完全下降的狀態下，以未利用鎖定部104鎖定繩CD之狀態放開繩CD。於是，日射遮蔽部件101利用自重下降。藉此，昇降繩102被從上樑130內拉出。因此，與昇降繩102連接的繩CD被朝向制動裝置1000的前方拉拽。於是，對繩CD賦予制動力。從而，日射遮蔽部件101的下降速度被抑制。因此，能夠抑制因日射遮蔽部件101的下降速度超過一定限度而產生的破損等。另外，對於該動作，利用後述的圖18詳細地進行說明。 On the other hand, in a state where the solar shielding member 101 is not completely lowered, the cord CD is released in a state where the cord CD is not locked by the locking portion 104. Then, the solar radiation shielding member 101 is lowered by its own weight. Thereby, the lifting rope 102 is pulled out from the upper beam 130. Therefore, the cord CD connected to the lifting cord 102 is pulled toward the front of the braking device 1000. Then, a braking force is applied to the rope CD. Therefore, the descending speed of the solar radiation shielding member 101 is suppressed. Therefore, it is possible to suppress damage or the like caused by the descending speed of the solar radiation shielding member 101 exceeding a certain limit. In addition, this operation will be described in detail with reference to FIG. 18 described later.

如以上所說明，根據本實施方式之遮蔽裝置100A，由於利用制動部件1000恰當地對能夠使日射遮蔽部件101昇降之繩CD的長度方向的移動賦予制動力，因此，即使在例如上述那樣日射遮蔽部件101利用自重下降之情形下，也能夠抑制日射遮蔽部件101的下降速度。 As described above, according to the shielding device 100A of the present embodiment, since the braking member 1000 is used to appropriately apply braking force to the movement in the longitudinal direction of the cord CD capable of raising and lowering the solar radiation shielding member 101, even when the solar radiation shielding member 101 is used, for example, Even when the component 101 is lowered by its own weight, the descending speed of the solar shielding component 101 can be suppressed.

第一前方繩***部201A和第二前方繩***部202A是用於在制動裝置1000組裝後將繩CD插通於排列部件200中之部件。第一前方繩***部201A形成為比第一前方槽201更寬。另外，第二前方繩***部202A形成為比第二前方槽202更寬。因此，透過將繩CD***第一前方繩***部201A和第二前方繩***部202A中，並保持原樣使繩CD朝向第一前方槽201和第二前方槽202的方向滑動，從而能夠順利地插通繩CD。 The first front cord insertion portion 201A and the second front cord insertion portion 202A are members for inserting the cord CD into the arrangement member 200 after the brake device 1000 is assembled. The first front cord insertion portion 201A is formed to be wider than the first front groove 201. In addition, the second front cord insertion portion 202A is formed to be wider than the second front groove 202. Therefore, by inserting the cord CD into the first front cord insertion portion 201A and the second front cord insertion portion 202A, and sliding the cord CD in the direction of the first front groove 201 and the second front groove 202 as it is, it is possible to smoothly Insert the cord CD.

另外，第一後方繩***部203A和第二後方繩***部204A是用於使***通於前方壁部205的繩CD通過後述滑塊220的前後的貫通孔225(參照圖13)，並將該繩CD從後方壁部206拉出至外部之部件。第一後方繩***部203A形成為比第一後方槽203更寬。另外，第二後方繩***部204A形成為比第二後方槽204更寬。因此，透過將繩CD***第一後方繩***部203A和第二後方繩***部204A中，並保持原樣使繩CD向第一後方槽203和第二後方槽204的方向滑動，從而能夠順利地插通繩CD。 In addition, the first rear cord insertion portion 203A and the second rear cord insertion portion 204A are used to pass the cord CD inserted into the front wall portion 205 through the through holes 225 (see FIG. 13) at the front and rear of the slider 220 described later, and The cord CD is pulled out from the rear wall portion 206 to the outside member. The first rear cord insertion portion 203A is formed to be wider than the first rear groove 203. In addition, the second rear cord insertion portion 204A is formed to be wider than the second rear groove 204. Therefore, by inserting the cord CD into the first rear cord insertion portion 203A and the second rear cord insertion portion 204A, and keeping the cord CD sliding in the direction of the first rear groove 203 and the second rear groove 204, it is possible to smoothly Insert the cord CD.

另外，第一前方繩***部201A、第二前方繩***部202A、第一後方繩***部203A以及第二後方繩***部204A的形狀為任意形狀，並不限定於圖10所示的形狀。例如，亦可為大致圓形，亦可從縱長形狀經過傾斜形狀後與第一前方槽201(其他槽也一樣)相連接。進而，在本實施方式中，第一前方繩***部201A和第一前方槽201之間設置有錯層210，但亦可不設置該錯層210，而將前方壁部205(或後方壁部206)設置為大致矩形。 In addition, the shapes of the first front rope insertion portion 201A, the second front rope insertion portion 202A, the first rear rope insertion portion 203A, and the second rear rope insertion portion 204A are arbitrary shapes and are not limited to the shapes shown in FIG. 10. For example, it may be substantially circular, or it may be connected to the first front groove 201 (the same applies to other grooves) after passing through an oblique shape from a longitudinal shape. Furthermore, in this embodiment, a staggered layer 210 is provided between the first front rope insertion portion 201A and the first front groove 201, but the staggered layer 210 may not be provided, and the front wall portion 205 (or the rear wall portion 206 ) Is set to a roughly rectangular shape.

如圖10(b)所示，在本實施方式中，前方壁部205和後方壁部206主視時呈大致相同形狀。因此，被從第一前方繩***部201A***的繩CD通過第一後方繩***部203A，被從第二前方繩***部202A***的繩CD通過第二後方繩***部204A。換言之，第一前方槽201和第一前方繩***部201A與第一後方槽203和第一後方繩***部203A是分別對應的一對槽，第二前方槽202和第二前方繩***部202A與第二後方槽204和第二後方繩***部204A是分別對應的一對槽。 As shown in FIG. 10(b), in this embodiment, the front wall part 205 and the rear wall part 206 have substantially the same shape in front view. Therefore, the cord CD inserted from the first front cord insertion portion 201A passes through the first rear cord insertion portion 203A, and the cord CD inserted from the second front cord insertion portion 202A passes through the second rear cord insertion portion 204A. In other words, the first front groove 201 and the first front rope insertion portion 201A, the first rear groove 203 and the first rear rope insertion portion 203A are a pair of grooves respectively corresponding to each other, and the second front groove 202 and the second front rope insertion portion 202A The second rear groove 204 and the second rear rope insertion portion 204A are a pair of grooves respectively corresponding to each other.

在此，如圖10(a)所示，在排列部件200的右側壁部207上設置有爪部209，該爪部209用於在制動裝置1000組裝期間從殼體10A的上方蓋上排列部件200而進行一體化時，與後述的殼體10A的卡合孔19(參照圖11)卡合而將排列部件200固定在殼體10A上。另外，圖10中雖未表示，但在左側壁部208的內面上以相對之方式設置有同樣的爪部209。藉此，能夠在右側壁部207和左側壁部208向外彈性變形的同時使殼體10A進入其中，並且，排列部件200上所設置的兩個爪部209與設置於殼體10A左右兩側的兩個卡合孔19彈性地卡合。 Here, as shown in FIG. 10(a), a claw portion 209 is provided on the right side wall portion 207 of the arrangement member 200, and the claw portion 209 is used to cover the arrangement member from above the housing 10A during assembly of the brake device 1000 When the 200 is integrated, it engages with an engagement hole 19 (see FIG. 11) of the housing 10A described later to fix the arrangement member 200 to the housing 10A. In addition, although not shown in FIG. 10, the same claws 209 are provided on the inner surface of the left side wall 208 so as to face each other. Thereby, it is possible to allow the housing 10A to enter while the right side wall portion 207 and the left side wall portion 208 are elastically deformed outwards, and the two claw portions 209 provided on the arranging member 200 are similar to those provided on the left and right sides of the housing 10A. The two engaging holes 19 are elastically engaged.

接著，利用圖11(a)、(b)和圖12對殼體10A進行說明。另外，以下在圖12中將朝向左方作為前方、朝向右方作為後方、朝向上方作為右側、朝向下方作為左側而進行說明。殼體10A與基座70一同構成框體，其內部保持有以下部件：亦即，滑塊220、螺旋彈簧SP、由軸芯41和輥部42構成之空轉輥40、滾花輥 240、小齒輪50、軸芯31、墊圈241、帶內齒的齒輪架260、行星齒輪280、板片300、帶恆星齒輪的平衡塊支架320、以及平衡塊340。 Next, the housing 10A will be described using FIGS. 11(a), (b), and FIG. 12. In addition, in FIG. 12, the description will be given below with the heading to the left as the front, the right as the rear, the upward as the right side, and the downward as the left side. The housing 10A and the base 70 constitute a frame body, and the following components are held inside: that is, the slider 220, the coil spring SP, the idle roller 40 composed of the shaft core 41 and the roller portion 42, and the knurled roller 240, pinion gear 50, shaft core 31, washer 241, gear carrier 260 with internal teeth, planetary gear 280, plate 300, balance weight support 320 with sun gear, and balance weight 340.

另外，殼體10A是與例如圖15所示的基座70一同構成制動裝置1000的框體之部件。另外，殼體10A是與例如圖15所示的帶恆星齒輪的平衡塊支架320及平衡塊340一同構成阻力賦予部之部件。 In addition, the housing 10A is a member that constitutes the frame of the brake device 1000 together with the base 70 shown in FIG. 15, for example. In addition, the housing 10A is a member that constitutes a resistance imparting section together with the weight holder 320 with sun gear and the weight 340 shown in FIG. 15, for example.

如圖11所示，作為主要構成，殼體10A具備以下各部：亦即，外形為大致正方形的頂壁部11，前側壁部12f，與前側壁部12f及頂壁部11相連接的右側壁部12r和左側壁部12l，與右側壁部12r和左側壁部12l分別連接的後側壁部12b，與頂壁部11相對且從前側壁部12f、後側壁部12b、右側壁部12r及左側壁部12l向徑向側延伸的凸緣部13，與凸緣部13連接的圓筒部13C，以及與圓筒部13C連接的蓋部112。 As shown in FIG. 11, as the main configuration, the housing 10A includes the following parts: namely, a top wall portion 11 having a substantially square outer shape, a front side wall portion 12f, and a right side wall connected to the front side wall portion 12f and the top wall portion 11 12r and the left side wall 12l, the rear side wall 12b connected to the right side wall 12r and the left side wall 12l, respectively, opposite the top wall 11 and from the front side wall 12f, the rear side wall 12b, the right side wall 12r and the left side wall The flange portion 13 extending toward the radial side of the portion 121, the cylindrical portion 13C connected to the flange portion 13, and the lid portion 112 connected to the cylindrical portion 13C.

前側壁部12f和後側壁部12b中形成有導向槽113。該兩個導向槽113在前後方向上彼此相對。該等導向槽113是用於在前後方向插通繩CD的槽。在此，插通導向槽113的繩CD的數量沒有特別限定，在本實施方式中示出了沿縱向插通三根繩CD的例子(參照圖4)。 Guide grooves 113 are formed in the front side wall portion 12f and the rear side wall portion 12b. The two guide grooves 113 are opposed to each other in the front-rear direction. These guide grooves 113 are grooves for inserting the cord CD in the front-rear direction. Here, the number of the cords CD inserted through the guide groove 113 is not particularly limited, and in this embodiment, an example in which three cords CD are inserted in the longitudinal direction is shown (see FIG. 4).

另外，右側壁部12r和左側壁部12l上設置有卡合孔19。卡合孔19如已述，是與排列部件200的爪部209卡合併將排列部件200固定在殼體10A上的部件。 In addition, engagement holes 19 are provided in the right side wall 12r and the left side wall 12l. The engagement hole 19 is a member that engages with the claw portion 209 of the alignment member 200 and fixes the alignment member 200 to the housing 10A as described above.

進而，在左右的卡合孔19的上方設置有支撐槽114。支撐槽114如圖4所示，是在殼體10A將滑塊220保持於內部時用於支撐設置在滑塊220上的突起230之部件。藉此，能夠以浮起狀態支撐滑塊220。另外，詳細情況後述。 Furthermore, support grooves 114 are provided above the left and right engagement holes 19. The support groove 114 is a member for supporting the protrusion 230 provided on the slider 220 when the housing 10A holds the slider 220 inside, as shown in FIG. 4. Thereby, the slider 220 can be supported in a floating state. In addition, the details will be described later.

頂壁部11中形成有第一頂壁槽16和第二頂壁槽17。如圖12(a)所示，第一頂壁槽16和第二頂壁槽17分別相對於繩CD的長度方向、亦即前後方向傾斜地形成，並且，隨著朝向繩CD長度方向的一側、亦即前方，第一頂壁槽16 和第二頂壁槽17之間的距離變小。即，另外，第一頂壁槽16形成為圓弧狀，並且，利用夾持導向斜面16a、釋放導向斜面16b、夾持側限制面16c以及釋放側限制面16d形成內周面。第一頂壁槽16的圓弧形成為俯視時與圖7所示的帶內齒的齒輪架260的內周面呈在同心圓上。 A first top wall groove 16 and a second top wall groove 17 are formed in the top wall portion 11. As shown in FIG. 12(a), the first ceiling wall groove 16 and the second ceiling wall groove 17 are respectively formed obliquely with respect to the longitudinal direction of the cord CD, that is, the front-rear direction, and as they move toward one side of the longitudinal direction of the cord CD , That is, the front, the first top wall groove 16 The distance from the second top wall groove 17 becomes smaller. That is, the first top wall groove 16 is formed in an arc shape, and the inner peripheral surface is formed by the clamping guide slope 16a, the release guide slope 16b, the clamping side restriction surface 16c, and the release side restriction surface 16d. The arc of the first top wall groove 16 is formed to be concentric with the inner peripheral surface of the gear carrier 260 with internal teeth shown in FIG. 7 when viewed from above.

另一方面，第二頂壁槽17形成為繪出緩和曲線的形狀，並且，利用夾持導向斜面17a、釋放導向斜面17b、夾持側限制面17c以及釋放側限制面17d形成內周面。具體而言，在第二頂壁槽17中，前方側形成為大致直線形的形狀，隨著朝向後方而向遠離第一頂壁槽16的方向彎曲。這是為了防止下述情況：亦即，在將第二頂壁槽17形成為大致直線狀之情形下，由於第一頂壁槽16是從後方朝向前方而靠近繩CD那樣的圓弧，因此，例如當軸芯31和軸芯41分別沿第一頂壁槽16和第二頂壁槽17移動時，軸芯31和軸芯41相對於繩CD的垂直方向的位移發生不同該一情況。亦即，這是因為：當一方為圓弧而另一方為大致直線狀時，在前後方向上朝向距繩CD的垂直距離不同。如此，透過使軸芯31和軸芯41的相對於繩CD的垂直方向的位移接近，從而滾花輥240和輥部42能夠適當地夾持繩CD。另外，第二頂壁槽17並不限定於此，例如，亦可形成為將與第一頂壁槽16大致同一形狀的槽朝向繩CD側彎曲之配置。藉此，能夠使軸芯31和軸芯41之相對於繩CD的垂直方向的位移為大致相同，從而能夠減少繩CD的磨損。 On the other hand, the second top wall groove 17 is formed in a shape that draws a gentle curve, and an inner peripheral surface is formed by the clamping guide slope 17a, the release guide slope 17b, the clamping side restriction surface 17c, and the release side restriction surface 17d. Specifically, in the second ceiling wall groove 17, the front side is formed in a substantially linear shape, and is curved in a direction away from the first ceiling wall groove 16 as it goes to the rear. This is to prevent the following situation: that is, in the case where the second ceiling wall groove 17 is formed in a substantially linear shape, since the first ceiling wall groove 16 is approaching from the rear to the front and approaching an arc like the cord CD, For example, when the shaft core 31 and the shaft core 41 move along the first top wall groove 16 and the second top wall groove 17 respectively, the displacement of the shaft core 31 and the shaft core 41 in the vertical direction relative to the rope CD is different. That is, this is because when one side is a circular arc and the other side is a substantially straight line, the vertical distance to the rope CD in the front-rear direction is different. In this way, by making the displacements of the shaft core 31 and the shaft core 41 in the vertical direction with respect to the cord CD approach, the knurled roller 240 and the roller portion 42 can appropriately clamp the cord CD. In addition, the second ceiling wall groove 17 is not limited to this, and for example, a groove having substantially the same shape as the first ceiling wall groove 16 may be bent toward the cord CD side. Thereby, the displacement of the axial core 31 and the axial core 41 with respect to the vertical direction of the rope CD can be made substantially the same, and the abrasion of the rope CD can be reduced.

在此，在第二實施方式中，不但盡可能地使軸芯31和軸芯41之相對於繩CD的垂直方向的位移相同，而且考慮了因其他部件的移動等產生的相互作用等，採用了圖12(a)所示的形狀。在此，在本實施方式中可以說第一頂壁槽16和第二頂壁槽17具有互不相同的曲率。 Here, in the second embodiment, not only the vertical displacement of the shaft core 31 and the shaft core 41 with respect to the rope CD is made the same as possible, but also the interaction caused by the movement of other parts etc. is taken into consideration. The shape shown in Fig. 12(a) is changed. Here, in this embodiment, it can be said that the first ceiling wall groove 16 and the second ceiling wall groove 17 have different curvatures from each other.

第一頂壁槽16的邊緣如圖11(a)、(b)、圖12(a)所示，在俯視殼體10A時，在第一頂壁槽16中之沿著殼體10A外側邊緣的位置的至少一部分上設置有從第一頂壁槽16向上方突出之第一導向壁16A。在本實施方式中，第一 導向壁16A相對於第一頂壁槽16呈大致90度。第一導向壁16A之目的係在於使沿著第一頂壁槽16移動的軸芯31的表面壓力降低。亦即，透過設置第一導向壁16A，與軸芯31接觸的面積增大，藉此降低軸芯31的表面壓力。這是因為：在對繩CD施加張力而制動裝置1000起作用的期間，軸芯31的表面壓力施加至第一頂壁槽16的內面，因該表面壓力而第一頂壁槽16的內面被磨削的話，滾花輥240和輥部42的間隔發生變化，從而存在針對滾花輥240的旋轉傳遞變得不充分之可能性。透過設置第一導向壁16A，能夠防止因來自軸芯31的壓力而殼體10A被磨削之情況。另外，第一導向壁16A的壁厚為任意厚度，考慮殼體10A的原材料、軸芯31的移動速度等而適當設計即可。 The edge of the first top wall groove 16 is shown in Figure 11 (a), (b), and Figure 12 (a). When the housing 10A is viewed from above, the first top wall groove 16 is along the outer edge of the housing 10A. A first guide wall 16A protruding upward from the first top wall groove 16 is provided on at least a part of the position. In this embodiment, the first The guide wall 16A is substantially 90 degrees with respect to the first top wall groove 16. The purpose of the first guide wall 16A is to reduce the surface pressure of the shaft core 31 moving along the first top wall groove 16. That is, by providing the first guide wall 16A, the contact area with the shaft core 31 is increased, thereby reducing the surface pressure of the shaft core 31. This is because the surface pressure of the shaft core 31 is applied to the inner surface of the first top wall groove 16 during the period when tension is applied to the rope CD and the brake device 1000 is active, and the inner surface of the first top wall groove 16 is caused by the surface pressure. If the surface is ground, the interval between the knurled roller 240 and the roller portion 42 changes, and the rotation transmission to the knurled roller 240 may become insufficient. By providing the first guide wall 16A, it is possible to prevent the housing 10A from being ground due to the pressure from the shaft core 31. In addition, the thickness of the first guide wall 16A may be any thickness, and it may be appropriately designed in consideration of the material of the housing 10A, the moving speed of the shaft core 31, and the like.

另外，俯視殼體10A時，在第二頂壁槽17之沿著殼體10A外側邊緣的位置中，沿著距離殼體10A的中心位於遠方的邊緣之位置的至少一部分上設置有從第二頂壁槽17向上方突出之第二導向壁17A。在本實施方式中，第二導向壁17A相對於第二頂壁槽17呈大致90度。第二導向壁17A之目的係在於使沿第二頂壁槽17移動的軸芯41的表面壓力降低。亦即，透過設置第二導向壁17A，與軸芯41接觸的面積增大，藉此降低軸芯41的表面壓力。這是因為：當對繩CD施加張力而制動裝置1000起作用的期間，軸芯41的表面壓力施加至第二頂壁槽17的內面，當因該表面壓力而第二頂壁槽17的內面被磨削的話，滾花輥240和輥部42的間隔發生變化，從而存在針對滾花輥240的旋轉傳遞變得不充分之可能性。透過設置第二導向壁17A，能夠防止因來自軸芯41的壓力而殼體10A被磨削的情況。另外，第二導向壁17A的壁厚為任意厚度，考慮殼體10A的原材料、軸芯41的移動速度等適當設計即可。 In addition, when the housing 10A is viewed from the top, in the second ceiling groove 17 along the outer edge of the housing 10A, at least a part of the second top wall groove 17 along the edge located far away from the center of the housing 10A is provided with a second A second guide wall 17A from which the top wall groove 17 protrudes upward. In this embodiment, the second guide wall 17A is substantially 90 degrees with respect to the second top wall groove 17. The purpose of the second guide wall 17A is to reduce the surface pressure of the shaft core 41 moving along the second top wall groove 17. That is, by providing the second guide wall 17A, the contact area with the shaft core 41 is increased, thereby reducing the surface pressure of the shaft core 41. This is because when tension is applied to the rope CD and the brake device 1000 is active, the surface pressure of the shaft core 41 is applied to the inner surface of the second top wall groove 17, and the second top wall groove 17 is affected by the surface pressure. If the inner surface is ground, the distance between the knurled roller 240 and the roller portion 42 changes, and there is a possibility that the rotation transmission to the knurled roller 240 may become insufficient. By providing the second guide wall 17A, it is possible to prevent the case 10A from being ground due to the pressure from the shaft core 41. In addition, the thickness of the second guide wall 17A may be any thickness, and it may be appropriately designed in consideration of the material of the housing 10A, the moving speed of the shaft core 41, and the like.

另外，在由金屬等堅固的材料成形殼體10A之情形下，亦可不設置第一導向壁16A和第二導向壁17A。這是因為：由於殼體10A很堅固，因此基本不存在因來自軸芯31和軸芯41的壓力而導致殼體10A被磨削之情況。 In addition, when the housing 10A is formed of a strong material such as metal, the first guide wall 16A and the second guide wall 17A may not be provided. This is because since the housing 10A is very strong, there is basically no case where the housing 10A is ground due to the pressure from the shaft core 31 and the shaft core 41.

凸緣部13是與頂壁部11相對、並從前側壁部12f、後側壁部12b、右側壁部12r以及左側壁部12l向徑向側延伸之部位，在本實施方式中形成為大致圓形。 The flange portion 13 is opposed to the top wall portion 11 and extends radially from the front side wall portion 12f, the rear side wall portion 12b, the right side wall portion 12r, and the left side wall portion 12l. In this embodiment, it is formed in a substantially circular shape. .

圓筒部13C與凸緣部13連接並位於內周齒輪115的外側。在本實施方式中，圓筒部13C形成為大致圓筒狀的形狀。 The cylindrical portion 13C is connected to the flange portion 13 and is located outside the inner peripheral gear 115. In this embodiment, the cylindrical portion 13C is formed in a substantially cylindrical shape.

蓋部112是連接於圓筒部13C並與基座70嵌合之部位。在本實施方式中，蓋部112的外邊緣形成為大致正方形。而且，蓋部112在左右側面的兩端上分別設置有兩個第一卡合槽111A。而且，在前端部的兩端設置有兩個第二卡合槽111B，在後端部的大致中央處設置有一個第二卡合槽111B。第一卡合槽111A是與圖6所示的基座70的第一卡合板部701A卡合之部件。另外，第二卡合槽111B是與基座70的第二卡合板部701B卡合之部件。藉此，殼體10A與基座70卡合，形成框體。 The cover 112 is a part connected to the cylindrical part 13C and fitted with the base 70. In this embodiment, the outer edge of the cover 112 is formed in a substantially square shape. In addition, the cover 112 is provided with two first engaging grooves 111A on both ends of the left and right side surfaces, respectively. Furthermore, two second engaging grooves 111B are provided at both ends of the front end, and one second engaging groove 111B is provided at the approximate center of the rear end. The first engaging groove 111A is a member that engages with the first engaging plate portion 701A of the base 70 shown in FIG. 6. In addition, the second engaging groove 111B is a member that engages with the second engaging plate portion 701B of the base 70. Thereby, the housing 10A is engaged with the base 70 to form a frame body.

接著，利用圖12(b)、圖14(a)及圖16對殼體10A的內部構造進行說明。如圖16所示，在殼體10A的內部形成有與行星齒輪280嚙合的環狀的內周齒輪115。接著，如圖12(b)和圖14(a)所示，在內周齒輪115的上部形成有俯視時呈大致環狀的波形部116。波形部116為如下形狀：亦即，距離通過內周齒輪115中心的圓的中心之水平距離小的部分和上述水平距離大的部分交替排列，俯視時呈Z字形該一形狀。具體而言，形成為連結多條直線而成的多角形形狀。在此，在本實施方式中以下述方式構成波形部116，亦即，距離通過內周齒輪115中心的圓的中心之水平距離大的部分與帶內齒的齒輪架260的一部分抵接，距離通過內周齒輪115中心的圓的中心之水平距離小的部分不與帶內齒的齒輪架260抵接該一方式。 Next, the internal structure of the housing 10A will be described using FIG. 12(b), FIG. 14(a), and FIG. 16. As shown in FIG. 16, a ring-shaped inner peripheral gear 115 that meshes with the planetary gear 280 is formed inside the housing 10A. Next, as shown in FIG. 12(b) and FIG. 14(a), a wave portion 116 having a substantially annular shape in a plan view is formed on the upper portion of the inner peripheral gear 115. The wave portion 116 has a shape in which a portion with a small horizontal distance from the center of a circle passing through the center of the inner peripheral gear 115 and a portion with a large horizontal distance are alternately arranged, and have a zigzag shape in a plan view. Specifically, it is formed in a polygonal shape formed by connecting a plurality of straight lines. Here, in this embodiment, the corrugated portion 116 is configured in such a manner that a portion having a large horizontal distance from the center of a circle passing through the center of the inner peripheral gear 115 abuts against a part of the gear carrier 260 with internal teeth. In this way, the part with a small horizontal distance from the center of the circle passing through the center of the inner gear 115 does not abut the gear carrier 260 with internal teeth.

進而，在殼體10A內部中的凸緣部13的內面側的面上，設置有在殼體10A的垂直方向上高度不同的錯層117。透過設置波形部116和錯層117，能夠容易地進 行例如帶內齒的齒輪架260等其他部件的定位且減少摩擦阻力，其中，帶內齒的齒輪架260是伴隨繩CD的移動以垂直方向的物理的或假想的旋轉軸為中心進行旋轉之旋轉部件之一例，亦即。另外，本實施方式中的帶內齒的齒輪架260是旋轉部件，同時，由於具備行星齒輪280，因此亦可說是將伴隨著繩CD向一方向的移動之滾花輥240的轉速增速並向阻力賦予部RA傳遞之增速部件。在此，所謂“物理的或假想的旋轉軸”，是指旋轉部件的旋轉軸為物理的軸之情況、或不存在物理的軸時的假想的軸(例如，平衡塊支架320(參照圖2、圖3)俯視時的通過中心點的垂直軸)之情況。 Furthermore, on the surface on the inner surface side of the flange portion 13 in the interior of the housing 10A, a staggered layer 117 having different heights in the vertical direction of the housing 10A is provided. By providing the corrugated part 116 and the staggered layer 117, it is possible to easily enter For example, the gear carrier 260 with internal teeth can be positioned to reduce frictional resistance. Among them, the gear carrier 260 with internal teeth rotates with the movement of the rope CD centered on a physical or imaginary rotation axis in the vertical direction. An example of a rotating part, namely. In addition, the gear carrier 260 with internal teeth in the present embodiment is a rotating member, and at the same time, because it is equipped with a planetary gear 280, it can also be said to increase the speed of the knurled roller 240 with the movement of the cord CD in one direction. And it is a speed-increasing component that is transmitted to the resistance imparting part RA. Here, the "physical or imaginary axis of rotation" refers to the case where the axis of rotation of the rotating member is a physical axis, or a virtual axis when there is no physical axis (for example, the weight bracket 320 (see FIG. 2) , Figure 3) The vertical axis passing through the center point when viewed from above.

另外，如圖14所示，在殼體10A的左右的內側面上形成有四個槽118。槽118是用於在組裝或拆卸制動裝置1000時使後述滑塊220的突起230通過之部件。在本實施方式中，由於滑塊220的突起230為四個，因此殼體10A上也設置有四個槽118。 In addition, as shown in FIG. 14, four grooves 118 are formed on the left and right inner surfaces of the housing 10A. The groove 118 is a member for passing the protrusion 230 of the slider 220 described later when the brake device 1000 is assembled or disassembled. In this embodiment, since there are four protrusions 230 of the slider 220, four grooves 118 are also provided on the housing 10A.

1-2-3<滑塊220> 1-2-3<slider 220>

接著，利用圖13對滑塊220進行說明。滑塊220相當於在內部保持有空轉輥40和滾花輥240且與空轉輥40和滾花輥240一同移動之移動部件。滑塊220具有頂壁部221、與頂壁部221連接的後側壁部222和前側壁部224、以及與後側壁部222和前側壁部224分別連接的底壁部223。 Next, the slider 220 will be described using FIG. 13. The slider 220 is equivalent to a moving member that holds the idler roller 40 and the knurled roller 240 inside and moves together with the idler roller 40 and the knurled roller 240. The slider 220 has a top wall portion 221, a rear side wall portion 222 and a front side wall portion 224 connected to the top wall portion 221, and a bottom wall portion 223 connected to the rear side wall portion 222 and the front side wall portion 224, respectively.

頂壁部221呈在大致矩形的形狀上形成有一對槽的形狀。該一對槽分別為第一頂壁槽226和第二頂壁槽227。第一頂壁槽226和第二頂壁槽227分別形成為沿著左右方向延伸的直線狀的槽，且相互排列在直線上。 The top wall portion 221 has a shape in which a pair of grooves are formed in a substantially rectangular shape. The pair of grooves are a first top wall groove 226 and a second top wall groove 227, respectively. The first ceiling wall groove 226 and the second ceiling wall groove 227 are respectively formed as linear grooves extending in the left-right direction, and are arranged on a straight line.

底壁部223與頂壁部221相對。在本實施方式中，底壁部223形成為與頂壁部221大致相同的形狀。但是，亦可使頂壁部221和底壁部223為不同的形狀。在底壁部223上也形成有沿著左右方向排列於直線上而形成的一對槽，該一對槽分別作為第一底壁槽228和第二底壁槽229。第一底壁槽228與第一頂壁槽226 在上下方向上相對，第二底壁槽229與第二頂壁槽227在上下方向上相對。因此，當俯視滑塊220時，如圖13(c)所示，上下槽重疊而能夠看見。 The bottom wall portion 223 is opposite to the top wall portion 221. In this embodiment, the bottom wall part 223 is formed in substantially the same shape as the top wall part 221. However, the top wall part 221 and the bottom wall part 223 may have different shapes. The bottom wall portion 223 is also formed with a pair of grooves arranged in a straight line along the left-right direction, and the pair of grooves serve as a first bottom wall groove 228 and a second bottom wall groove 229, respectively. The first bottom wall groove 228 and the first top wall groove 226 Opposite in the vertical direction, the second bottom wall groove 229 and the second top wall groove 227 are opposed in the vertical direction. Therefore, when the slider 220 is viewed from above, as shown in FIG. 13(c), the upper and lower grooves overlap and can be seen.

在此，第一頂壁槽226和第一底壁槽228的寬度是可容納軸芯31直徑的程度的大小。另外，第二頂壁槽227和第二底壁槽229的寬度是可容納軸芯41直徑的程度的大小。 Here, the width of the first top wall groove 226 and the first bottom wall groove 228 is a size that can accommodate the diameter of the shaft core 31. In addition, the widths of the second top wall groove 227 and the second bottom wall groove 229 are large enough to accommodate the diameter of the shaft core 41.

另外，在頂壁部221的四角上，以朝向頂壁部221的左右突出之方式設置有突起230。如圖4所示，突起230是被收納在殼體10A的支撐槽114中、且用於在殼體10A內部以浮起狀態支撐滑塊220之部件。亦即，滑塊220以不與位於下方的帶內齒的齒輪架260接觸之狀態被保持。 In addition, the four corners of the top wall 221 are provided with protrusions 230 so as to protrude toward the left and right of the top wall 221. As shown in FIG. 4, the protrusion 230 is a member that is received in the support groove 114 of the housing 10A and used to support the slider 220 in a floating state inside the housing 10A. That is, the slider 220 is held in a state where it is not in contact with the gear carrier 260 with internal teeth located below.

前側壁部224和後側壁部222上形成有貫通孔225。貫通孔225在前側壁部224和後側壁部222的寬度方向的大致中央處沿前後方向貫通前側壁部224和後側壁部222。孔的形狀為任意形狀，但至少為能夠供一根繩CD插通的程度。較佳為能夠使多根繩CD以在縱向整齊排列之狀態插通的形狀。另外，本實施方式中形成為在上下方向上長的大致長圓形的形狀。 Through holes 225 are formed in the front side wall portion 224 and the rear side wall portion 222. The through hole 225 penetrates the front side wall portion 224 and the rear side wall portion 222 in the front-rear direction at substantially the center of the width direction of the front side wall portion 224 and the rear side wall portion 222. The shape of the hole is arbitrary, but it is at least to the extent that a cord CD can be inserted through. It is preferably a shape capable of inserting a plurality of cords CD in a state of being neatly arranged in the longitudinal direction. In addition, in the present embodiment, it is formed in a substantially oblong shape that is long in the vertical direction.

另外，如圖13(b)所示，在後側壁部222中，在貫通孔225的兩側形成有從後側壁部222的外側面形成的凹部231。凹部231的形狀為任意形狀，既可以為如圖13(b)所示之從貫通孔225切至側面側的切口形狀，亦可為大致圓形、大致矩形的凹口等。另外，在本實施方式中，左側的凹部231內配置有螺旋彈簧SP，螺旋彈簧SP的一端從凹部231突出。而且，在組裝制動裝置1000時，螺旋彈簧SP與殼體10A的內壁抵接，對滑塊220施加朝向前方的力。另外，圖13中省略了螺旋彈簧SP的從凹部231突出的部分。另外，亦可在右側的凹部231內配置螺旋彈簧SP。進而，亦可在左右兩側的凹部231內均配置有螺旋彈簧SP。 In addition, as shown in FIG. 13( b ), in the rear side wall portion 222, recesses 231 formed from the outer side surface of the rear side wall portion 222 are formed on both sides of the through hole 225. The shape of the recess 231 may be any shape, and may be a notch shape cut from the through hole 225 to the side surface as shown in FIG. 13(b), or may be a substantially circular, substantially rectangular notch, or the like. In addition, in this embodiment, the coil spring SP is arranged in the concave portion 231 on the left side, and one end of the coil spring SP protrudes from the concave portion 231. In addition, when the brake device 1000 is assembled, the coil spring SP abuts against the inner wall of the housing 10A and applies a forward force to the slider 220. In addition, the portion of the coil spring SP protruding from the recess 231 is omitted in FIG. 13. In addition, the coil spring SP may be arranged in the recess 231 on the right side. Furthermore, the coil spring SP may be arrange|positioned in the recessed part 231 of both left and right sides.

如此形狀的滑塊220的左右方向的大小與殼體10A寬度方向的內壁間的距離大致相同，滑塊220的前後方向的大小比殼體10A前後方向的內壁間的 距離小。因此，當將滑塊220配置於殼體10A的空間內時，滑塊220的頂壁部221和底壁部223的側面與殼體10A寬度方向的內壁面抵接，滑塊220相對於殼體10A在寬度方向上被限制移動。在該狀態下，殼體10A的導向槽113和滑塊220的貫通孔225相互在前後方向上排列。亦即，貫通孔225是用於將繩CD插通於滑塊220內的孔。另一方面，在滑塊220已被配置於殼體10A的空間內之狀態下，滑塊220與殼體10A的內壁面之間在前後方向上產生空隙，滑塊220相對於殼體10A能夠在前後方向上移動。另外，在滑塊220已被配置於殼體10A的空間內之狀態下，從滑塊220的後側壁部222的凹部231突出的螺旋彈簧SP推壓殼體10A的後方的內壁。因此，在滑塊220已被配置於殼體10A的空間內之狀態下，滑塊220位於前方側，呈在殼體10A內被推壓向前方的狀態。 The size of the slider 220 in this shape in the left-right direction is approximately the same as the distance between the inner walls of the housing 10A in the width direction, and the size of the slider 220 in the front-rear direction is larger than the distance between the inner walls of the housing 10A. The distance is small. Therefore, when the slider 220 is arranged in the space of the housing 10A, the side surfaces of the top wall portion 221 and the bottom wall portion 223 of the slider 220 abut the inner wall surface in the width direction of the housing 10A, and the slider 220 is opposed to the housing 10A. The body 10A is restricted from moving in the width direction. In this state, the guide groove 113 of the housing 10A and the through hole 225 of the slider 220 are aligned in the front-rear direction. That is, the through hole 225 is a hole for inserting the cord CD into the slider 220. On the other hand, in a state where the slider 220 has been arranged in the space of the housing 10A, a gap is generated between the slider 220 and the inner wall surface of the housing 10A in the front-to-rear direction, and the slider 220 can be relative to the housing 10A. Move in the front and back direction. In addition, in a state where the slider 220 has been arranged in the space of the housing 10A, the coil spring SP protruding from the recess 231 of the rear side wall portion 222 of the slider 220 presses the rear inner wall of the housing 10A. Therefore, in a state in which the slider 220 has been arranged in the space of the housing 10A, the slider 220 is located on the front side and is pushed forward in the housing 10A.

在此，利用圖14對滑塊220的突起230詳細地進行說明。如圖14所示，在組裝制動裝置1000時，以滑塊220位於殼體10A內部的下方之方式進行配置，且使兩者以靠近之方式在上下方向相對移動。接著，使滑塊220上所設置的突起230通過設置於殼體10A內部的槽118。另外，在圖14(a)中為了提高可見性，強調顯示了槽118。接著，如圖4所示，使殼體10A和滑塊220靠近直至突起230到達支撐槽114。於是，設置在滑塊220上的螺旋彈簧SP與殼體10A的後方內壁抵接，透過對滑塊220賦予朝向前方的作用力，從而突起230位於比槽118更前方的位置。因此，一旦將滑塊220安裝在殼體10A上，就能夠防止突起230從支撐槽114中脫落。另外，槽118不僅在制動裝置1000組裝時、而且在制動裝置1000拆卸時也起到使突起230通過之作用。該情況下，抵抗螺旋彈簧SP的作用力使滑塊220相對於殼體10A向後方相對地移動，當突起230到達槽118的位置時，使滑塊220相對於殼體10A向下側相對移動即可。 Here, the protrusion 230 of the slider 220 will be described in detail with reference to FIG. 14. As shown in FIG. 14, when assembling the brake device 1000, the slider 220 is arranged so that it is located below the inside of the housing 10A, and the two move relatively in the vertical direction so as to approach. Next, the protrusion 230 provided on the slider 220 is passed through the groove 118 provided in the housing 10A. In addition, in FIG. 14(a), in order to improve visibility, the groove 118 is highlighted. Next, as shown in FIG. 4, the housing 10A and the slider 220 are brought close until the protrusion 230 reaches the supporting groove 114. Then, the coil spring SP provided on the slider 220 abuts against the rear inner wall of the housing 10A, and by applying a forward urging force to the slider 220, the protrusion 230 is positioned in front of the groove 118. Therefore, once the slider 220 is mounted on the housing 10A, the protrusion 230 can be prevented from falling out of the supporting groove 114. In addition, the groove 118 not only functions to allow the protrusion 230 to pass through not only when the brake device 1000 is assembled, but also when the brake device 1000 is disassembled. In this case, the slider 220 is relatively moved backward with respect to the housing 10A against the urging force of the coil spring SP, and when the protrusion 230 reaches the position of the groove 118, the slider 220 is relatively moved downward with respect to the housing 10A That's it.

利用如此的構成，能夠在殼體10A內部以浮起狀態支撐滑塊220。因此，能夠防止滑塊220與其他部件、例如帶內齒的齒輪架260等的接觸，從而能夠降低或消除不必要的阻力。因此，能夠減少各部件的消耗。 With such a configuration, the slider 220 can be supported in a floating state inside the housing 10A. Therefore, it is possible to prevent the slider 220 from contacting other components, such as the gear frame 260 with internal teeth, and thus it is possible to reduce or eliminate unnecessary resistance. Therefore, the consumption of each component can be reduced.

1-2-4<空轉輥40、滾花輥240及小齒輪50> 1-2-4<idle roller 40, knurled roller 240 and pinion 50>

接著，利用圖3和圖15對空轉輥40、滾花輥240及小齒輪50進行說明。 Next, the idler roller 40, the knurled roller 240, and the pinion gear 50 will be described using FIGS. 3 and 15.

空轉輥40由輥部42和軸芯41構成。另外，空轉輥40具有與滾花輥240的軸芯31平行之軸芯41、和包覆軸芯41的外周面之輥部42。因此，滾花輥240的旋轉軸和空轉輥40的旋轉軸相互平行。空轉輥40的輥部42的外徑比滾花輥240的外徑大。空轉輥40的輥部42的外周面呈摩擦係數比金屬的平坦面的摩擦係數高的狀態。另外，軸芯41的兩端部從輥部42露出。 The idle roller 40 is composed of a roller portion 42 and a shaft core 41. In addition, the idle roller 40 has a shaft core 41 parallel to the shaft core 31 of the knurled roller 240 and a roller portion 42 covering the outer peripheral surface of the shaft core 41. Therefore, the rotation axis of the knurled roller 240 and the rotation axis of the idler roller 40 are parallel to each other. The outer diameter of the roller portion 42 of the idle roller 40 is larger than the outer diameter of the knurled roller 240. The outer peripheral surface of the roller portion 42 of the idler roller 40 is in a state where the coefficient of friction is higher than that of a flat surface of metal. In addition, both end portions of the shaft core 41 are exposed from the roller portion 42.

軸芯31的一端***滾花輥240的中心。而且，在軸芯31的另一端上插有小齒輪50。滾花輥240能夠以任意材料形成，例如可以使用不銹鋼。 One end of the shaft core 31 is inserted into the center of the knurling roller 240. In addition, a pinion gear 50 is inserted into the other end of the shaft core 31. The knurling roller 240 can be formed of any material, and for example, stainless steel can be used.

空轉輥40和滾花輥240被保持在滑塊220的內部。另外，小齒輪50被保持在滑塊220的外部。在此，利用圖9對滾花輥240、滑塊220及小齒輪50的位置關係進行說明。圖9是從本實施方式之制動裝置1000的左側面觀察的、通過軸芯31的大致中心的剖視圖的一部分。如圖9所示，制動裝置1000在組裝時成為以滾花輥240和小齒輪50夾著滑塊220的底壁部223這樣的構成。另外，在本實施方式中，為了減少小齒輪50與滑塊220的接觸面積，而在小齒輪50上設置有錯層51。藉此，當經由軸芯31而滾花輥240和小齒輪50一體旋轉時，能夠減小小齒輪50與滑塊220之間的滑動阻力。藉此，能夠使旋轉動作變得順暢。另外，為了降低阻力，在本實施方式中，在小齒輪50的下側於軸芯31上插有墊圈241(參照圖2和圖3)。 The idler roller 40 and the knurled roller 240 are held inside the slider 220. In addition, the pinion gear 50 is held outside the slider 220. Here, the positional relationship among the knurling roller 240, the slider 220, and the pinion gear 50 will be described with reference to FIG. 9. FIG. 9 is a part of a cross-sectional view passing through the approximate center of the shaft core 31 viewed from the left side surface of the brake device 1000 of the present embodiment. As shown in FIG. 9, the brake device 1000 has a structure in which the bottom wall portion 223 of the slider 220 is sandwiched by the knurled roller 240 and the pinion gear 50 during assembly. In addition, in this embodiment, in order to reduce the contact area between the pinion gear 50 and the slider 220, the pinion gear 50 is provided with a staggered layer 51. Thereby, when the knurling roller 240 and the pinion gear 50 rotate integrally via the shaft core 31, the sliding resistance between the pinion gear 50 and the slider 220 can be reduced. Thereby, the rotation operation can be made smooth. In addition, in order to reduce resistance, in this embodiment, a washer 241 is inserted into the shaft core 31 under the pinion gear 50 (refer to FIGS. 2 and 3).

1-2-5<帶內齒的齒輪架260和行星齒輪280> 1-2-5<Gear carrier 260 with internal teeth and planetary gear 280>

接著，利用圖2和圖15對帶內齒的齒輪架260和行星齒輪280進行說明。在本實施方式中，帶內齒的齒輪架260俯視時為大致麵包圈形。帶內齒的齒輪架260具備俯視時為從圓柱部264向外側突出的凸緣262。 Next, the carrier 260 with internal teeth and the planetary gear 280 will be described with reference to FIGS. 2 and 15. In this embodiment, the gear carrier 260 with internal teeth is substantially doughnut-shaped in a plan view. The gear carrier 260 with internal teeth includes a flange 262 that protrudes outward from the cylindrical portion 264 in a plan view.

在圓柱部264的內側的內周面上形成有與小齒輪50嚙合的內齒輪261。而且，在凸緣262上形成有在垂直方向上朝下突出的支撐軸263。支撐軸263的個數沒有特別限定，但是特別較佳呈等間隔。另外，在本實施方式中，作為一例而構成為設置有四個支撐軸263。 An internal gear 261 meshing with the pinion gear 50 is formed on the inner peripheral surface of the inner side of the cylindrical portion 264. Also, a support shaft 263 protruding downward in the vertical direction is formed on the flange 262. The number of support shafts 263 is not particularly limited, but is particularly preferably at equal intervals. In addition, in this embodiment, four support shafts 263 are provided as an example.

而且，在支撐軸263上分別以能夠旋轉之方式支撐有行星齒輪280。行星齒輪280與後述的恆星齒輪323和設置在殼體10A內部的內周齒輪115相互嚙合。並且，能夠以內齒輪261的中心部為中心進行公轉。因此，透過小齒輪50的旋轉被傳遞至內齒輪261，帶內齒的齒輪架260進行旋轉，伴隨於此，以能夠旋轉之方式支撐於帶內齒的齒輪架260的凸緣262上所設置的支撐軸263上之行星齒輪280進行旋轉，藉此，能夠使起因於小齒輪50的旋轉增速。另外，行星齒輪280上設置有錯層281。利用該錯層，能夠避免與其他部件的接觸。 In addition, planetary gears 280 are rotatably supported on the support shafts 263, respectively. The planetary gear 280 meshes with a sun gear 323 described later and an inner peripheral gear 115 provided inside the housing 10A. In addition, it is possible to revolve around the center portion of the internal gear 261. Therefore, the rotation of the pinion gear 50 is transmitted to the internal gear 261, and the gear carrier 260 with internal teeth rotates. Along with this, it is rotatably supported on the flange 262 of the gear carrier 260 with internal teeth. The planetary gear 280 on the support shaft 263 rotates, whereby the rotation of the pinion gear 50 can be increased. In addition, a staggered layer 281 is provided on the planetary gear 280. By using this staggered layer, it is possible to avoid contact with other parts.

1-2-6<帶恆星齒輪的平衡塊支架320和平衡塊340> 1-2-6<Balance weight bracket 320 and balance weight 340 with sun gear>

接著，利用圖2和圖15對帶恆星齒輪的平衡塊支架320和平衡塊340進行說明。平衡塊340是載置於殼體10A內的基座70上且利用來自制動對象的旋轉輸入朝徑向外側施加離心力之離心擴張部之一例。帶恆星齒輪的平衡塊支架320朝向環狀的環部324的外側交替地排列形成有凸部321和凹部322。在此，凸部321是帶恆星齒輪的平衡塊支架320自轉時與平衡塊340的側面抵接之部件。如圖15所示，在環部324外側的外周面上，與行星齒輪280嚙合的恆星齒輪323以旋轉軸朝向與凸部321的延伸方向大致垂直的方向而設置。而且，各個凹部322中配置有平衡塊340。亦即，帶恆星齒輪的平衡塊支架320亦可說是在制動裝置1000組裝時以凸部321作為分界而在各個凹部322內保持平衡塊340之部件。另外，平衡塊340的數量 為任意個，從旋轉時的平衡之觀點出發，較佳呈等間隔。另外，在本實施方式中，作為一例而使用八個平衡塊340。因此，凸部321和凹部322也分別各設置為八個。即，凹部322分別呈等間隔且距離帶恆星齒輪的平衡塊支架320的自轉中心呈等距離地配置。 Next, the balance weight holder 320 with sun gear and the balance weight 340 will be described using FIGS. 2 and 15. The balance weight 340 is an example of a centrifugal expansion part that is placed on the base 70 in the housing 10A and applies a centrifugal force to the radially outer side by the rotation input from the braking target. The balance weight holder 320 with sun gear is alternately arranged with convex parts 321 and concave parts 322 toward the outside of the annular ring part 324. Here, the convex portion 321 is a member that abuts against the side surface of the balance weight 340 when the balance weight holder 320 with a sun gear rotates. As shown in FIG. 15, on the outer peripheral surface of the outer side of the ring portion 324, the sun gear 323 meshing with the planetary gear 280 is provided with the rotation axis oriented in a direction substantially perpendicular to the extending direction of the convex portion 321. In addition, a balance weight 340 is arranged in each recess 322. That is, the balance weight bracket 320 with sun gear can also be said to be a component that holds the balance weight 340 in each recess 322 by using the convex portion 321 as a boundary when the brake device 1000 is assembled. In addition, the number of balance weights 340 The number is arbitrary, and is preferably at equal intervals from the viewpoint of balance during rotation. In addition, in this embodiment, eight balance weights 340 are used as an example. Therefore, the convex portions 321 and the concave portions 322 are also provided at eight respectively. That is, the recesses 322 are respectively arranged at equal intervals and at equal distances from the center of rotation of the balance weight holder 320 with sun gear.

在本實施方式中，在各平衡塊340上於基座70側設置有突起341。藉此，在平衡塊340與基座70的接觸面的至少一部分上設置有錯層。因此，能夠減少與基座70抵接時的阻力。突起341的數量為任意個，在本實施方式中，作為一例而設置有四個突起341。 In this embodiment, each balance weight 340 is provided with a protrusion 341 on the side of the base 70. Thereby, at least a part of the contact surface between the balance weight 340 and the base 70 is provided with a staggered layer. Therefore, the resistance at the time of contact with the base 70 can be reduced. The number of protrusions 341 is arbitrary, and in this embodiment, four protrusions 341 are provided as an example.

平衡塊340是如下所述的部件：亦即，在由小齒輪50引起的旋轉時，利用離心力向遠離內齒輪261中心的方向移動並與殼體10A的內周壁抵接，藉此作為離心制動器對旋轉賦予阻力該一部件。因此，利用殼體10A的內周壁、帶恆星齒輪的平衡塊支架320以及平衡塊340，能夠發揮作為阻力賦予部的作用。 The balance weight 340 is a member that, when the pinion gear 50 rotates, moves away from the center of the internal gear 261 by centrifugal force and abuts against the inner peripheral wall of the housing 10A, thereby acting as a centrifugal brake This component imparts resistance to rotation. Therefore, the inner peripheral wall of the housing 10A, the weight holder 320 with sun gear, and the weight 340 can function as a resistance imparting portion.

另外，在制動裝置1000組裝時，帶內齒的齒輪架260和帶恆星齒輪的平衡塊支架320經由板片300而被組裝。具體而言，以將帶內齒的齒輪架260的圓柱部264***帶恆星齒輪的平衡塊支架320的環部324中之方式進行組裝。因此，圓柱部264的直徑設計成比環部324的直徑稍小。 In addition, when the brake device 1000 is assembled, the gear carrier 260 with internal teeth and the balance weight carrier 320 with the sun gear are assembled via the plate 300. Specifically, the assembly is performed by inserting the cylindrical portion 264 of the gear holder 260 with internal teeth into the ring portion 324 of the balance weight holder 320 with sun gear. Therefore, the diameter of the cylindrical portion 264 is designed to be slightly smaller than the diameter of the ring portion 324.

在此，板片300具有在防止行星齒輪280傾斜的同時防止行星齒輪280與平衡塊340發生干擾之功能。另外，為了使制動裝置1000整體的厚度變薄，平衡塊340較佳盡可能薄地形成。進而，板片300由於薄薄地形成，因此較佳為金屬制，在技術上能夠實現之情形下，板片300亦可以樹脂形成。該情況下，亦可與恆星齒輪323呈一體地形成。 Here, the plate 300 has the function of preventing the planetary gear 280 from interfering with the balance weight 340 while preventing the planetary gear 280 from tilting. In addition, in order to reduce the thickness of the entire braking device 1000, the balance weight 340 is preferably formed as thin as possible. Furthermore, since the plate 300 is thinly formed, it is preferably made of metal. If it is technically possible, the plate 300 may also be formed of resin. In this case, it may be formed integrally with the sun gear 323.

Fig. 4 is an assembly diagram of the brake device 1000 constructed by combining the above-mentioned components. As shown in FIG. 4, the appearance of the brake device 1000 is a frame formed by connecting a housing 10A and a base 70, and an arrangement member arranged to be covered from above the housing 10A 200 constitute.

At this time, the knurling roller 240 is located inside the slider 220, and the pinion gear 50 is located outside the slider 220. In addition, the shaft core 41 is slid while moving in the horizontal direction in the second top wall groove 227 and the second bottom wall groove 229. At this time, the roller 42 is located inside the slider 220. Next, the slider 220 and the gear carrier 260 with internal teeth are relatively moved so as to be close to each other, so that the internal gear 261 and the pinion gear 50 provided on the gear carrier 260 with internal teeth mesh with each other.

其後，在該等部件的下側配置基座70，如圖14所示，以滑塊220的突起230通過殼體10A的槽118之方式從上方覆蓋殼體10A。此時，設置在滑塊220上的螺旋彈簧SP與殼體10A的內周壁抵接，對滑塊220賦予朝向前方的作用力，確認突起230不會從支撐槽114中脫落。接著，使殼體10A上設置的第一卡合槽111A和第二卡合槽111B與基座70上所設置的第一卡合板部701A和第二卡合板部701B相互卡合，從而將殼體10A和基座70固定。 After that, the base 70 is arranged on the lower side of these components, and as shown in FIG. 14, the housing 10A is covered from above so that the protrusion 230 of the slider 220 passes through the groove 118 of the housing 10A. At this time, the coil spring SP provided on the slider 220 abuts against the inner peripheral wall of the housing 10A, applies a forward urging force to the slider 220, and confirms that the protrusion 230 does not fall out of the support groove 114. Next, the first engaging groove 111A and the second engaging groove 111B provided on the housing 10A and the first engaging plate portion 701A and the second engaging plate portion 701B provided on the base 70 are engaged with each other, so that the housing The body 10A and the base 70 are fixed.

最後，從由殼體10A和基座70構成之框體的上方蓋上排列部件200。接著，使排列部件200上所設置的爪部209與殼體10A上所設置的卡合孔19卡合，從而將排列部件200和殼體10A固定。 Finally, the arrangement member 200 is covered from above the frame composed of the housing 10A and the base 70.

Next, the second cord CD passes through the first rear cord insertion portion 203A provided on the rear wall portion 206 of the arranging member 200 from the first rear groove 203 to the outside. Next, the third cord CD passes through the second rear cord insertion portion 204A from the second rear groove 204 to the outside. Thereby, it becomes the state shown to Fig.4 (a), (b).

圖4(c)是制動裝置1000的左側視圖，亦即，從圖4(a)的箭頭X方向觀察之側視圖。如圖4(c)所示，制動裝置1000側視時，從上側開始能夠確認到殼體10A、排列部件200、基座70。另外，可知突起230被支撐槽114支撐。 Fig. 4(c) is a left side view of the brake device 1000, that is, a side view viewed from the arrow X direction of Fig. 4(a). As shown in FIG. 4(c), when the brake device 1000 is viewed from the side, the housing 10A, the arrangement member 200, and the base 70 can be confirmed from the upper side. In addition, it can be seen that the protrusion 230 is supported by the support groove 114.

如圖5(a)所示，制動裝置1000俯視時，從中心開始能夠依次確認到殼體10A、排列部件200、基座70的一部分。在此，如圖4(a)、(b)及圖5(a)所示，軸芯31的上端從設置在滑塊220上的第一頂壁槽226插通設置在殼體10A上的第一頂壁槽16，並露出於殼體10A的外部。同樣地，軸芯41的上端從設置在滑塊220上的第二頂壁槽227插通設置在殼體10A上的第二頂壁槽17，並露出於殼體10A的外部。 As shown in FIG. 5(a), when the brake device 1000 is viewed from above, it is possible to confirm a part of the housing 10A, the arrangement member 200, and the base 70 in order from the center. Here, as shown in FIGS. 4(a), (b) and 5(a), the upper end of the shaft core 31 is inserted from the first top wall groove 226 provided on the slider 220 through the housing 10A The first top wall groove 16 is exposed to the outside of the housing 10A. Similarly, the upper end of the shaft core 41 is inserted from the second top wall groove 227 provided on the slider 220 through the second top wall groove 17 provided on the housing 10A, and is exposed to the outside of the housing 10A.

接著，設置在第一頂壁槽16的邊緣的第一導向壁16A與軸芯31抵接，設置在第二頂壁槽17的邊緣的第二導向壁17A與軸芯41抵接。 Next, the first guide wall 16A provided on the edge of the first top wall groove 16 abuts the shaft core 31, and the second guide wall 17A provided on the edge of the second top wall groove 17 abuts the shaft core 41.

另外，如圖5(b)所示，基座70仰視時，能夠確認到插通在第一基座槽706中的軸芯31的下端和插通在第二基座槽707中的軸芯41的下端。另外，在設置有安裝筒702的面中亦可形成為：利用面覆蓋圓柱部708的上方，從而從外部覆蓋軸芯31和軸芯41下端該一構成。 In addition, as shown in FIG. 5(b), when the base 70 is viewed from the bottom, it can be confirmed that the lower end of the shaft core 31 inserted in the first base groove 706 and the shaft core inserted in the second base groove 707 can be confirmed The lower end of 41. In addition, the surface on which the mounting cylinder 702 is provided may be formed to cover the upper part of the cylindrical portion 708 with the surface to cover the shaft core 31 and the lower end of the shaft core 41 from the outside.

1-3-1<組裝狀態下的內部結構> 1-3-1 <Internal structure in assembled state>

接著，利用圖6~圖8對組裝狀態下的內部結構進行說明。圖6是從圖4的狀態拆下排列部件200和殼體10A後之狀態下的立體圖。如圖6所示，軸芯31和軸芯41突出於滑塊220的上方。另外，軸芯31在第一頂壁槽226內於滑塊220的寬度方向上被限制移動。同樣地，軸芯41在第二頂壁槽227內於滑塊220的寬度方向上被限制移動。另外，省略了圖示的繩CD以縱向整齊排列之狀態沿滑塊220的前後方向插通於滑塊220的貫通孔225。 Next, the internal structure in the assembled state will be described using FIGS. 6 to 8. FIG. 6 is a perspective view of the state in which the arrangement member 200 and the housing 10A are removed from the state of FIG. 4. As shown in FIG. 6, the shaft core 31 and the shaft core 41 protrude above the slider 220. In addition, the shaft core 31 is restricted from moving in the width direction of the slider 220 in the first top wall groove 226. Similarly, the shaft core 41 is restricted from moving in the width direction of the slider 220 in the second top wall groove 227. In addition, the cord CD not shown in the figure is inserted into the through hole 225 of the slider 220 along the front-rear direction of the slider 220 in a state of being aligned vertically.

圖7是從圖6的狀態進一步拆下滑塊220後之狀態下的立體圖。省略了圖示的繩CD以被滾花輥240和輥部42夾持之狀態插通於制動裝置1000的前後。另外，小齒輪50與內齒輪261相互嚙合。因此，當對繩CD施加了張力時，在繩CD與滾花輥240之間產生摩擦力，藉此與滾花輥240成為一體而小齒輪50進行旋轉的話，小齒輪50的旋轉被傳遞至內齒輪261。其結果是，透過內齒輪261進行自轉，帶內齒的齒輪架260和設置在其凸緣262的支撐軸263也進行公轉。伴隨於此，以能夠旋轉之方式支撐於支撐軸263上的行星齒輪280在自轉的同時開始公轉。 FIG. 7 is a perspective view of the state in which the slider 220 is further removed from the state of FIG. 6. The cord CD (not shown) is inserted into the front and back of the brake device 1000 in a state of being sandwiched between the knurled roller 240 and the roller portion 42. In addition, the pinion gear 50 and the internal gear 261 mesh with each other. Therefore, when tension is applied to the rope CD, a frictional force is generated between the rope CD and the knurled roller 240, thereby being integrated with the knurling roller 240 and the pinion 50 rotates, the rotation of the pinion 50 is transmitted to Internal gear 261. As a result, the internal gear 261 rotates, and the gear carrier 260 with internal teeth and the support shaft 263 provided on the flange 262 also revolve. Along with this, the planetary gear 280 rotatably supported on the support shaft 263 starts to revolve while rotating.

圖8是從圖7的狀態進一步拆下帶內齒的齒輪架260的狀態下的立體圖。如圖8所示，行星齒輪280和恆星齒輪323相互嚙合。因此，行星齒輪280的旋轉被傳遞至恆星齒輪323，帶恆星齒輪的平衡塊支架320開始自轉。其結果是如圖15所示，被保持在帶恆星齒輪的平衡塊支架320的凹部322中之平衡塊340開始自轉。接著，當轉速超過一定值時，由於離心力而平衡塊340與殼體10A的內壁抵接。藉此，對滾花輥240的旋轉賦予阻力。 FIG. 8 is a perspective view of a state in which the gear carrier 260 with internal teeth is further removed from the state of FIG. 7. As shown in FIG. 8, the planetary gear 280 and the sun gear 323 mesh with each other. Therefore, the rotation of the planetary gear 280 is transmitted to the sun gear 323, and the balance weight support 320 with the sun gear starts to rotate. As a result, as shown in FIG. 15, the weight 340 held in the recess 322 of the weight holder 320 with sun gear starts to rotate. Then, when the rotation speed exceeds a certain value, the balance weight 340 abuts against the inner wall of the housing 10A due to centrifugal force. Thereby, resistance is given to the rotation of the knurled roller 240.

接著，利用圖16和圖17對組裝狀態下的各部件之間的相對位置更詳細地進行說明。圖16是圖4(c)的A-A線切斷部之剖視圖。如圖16所示，以軸芯31為中心的小齒輪50與設置在帶內齒的齒輪架260上的內齒輪261相互嚙合。另外，構成為：內齒輪261的旋轉經由帶內齒的齒輪架260的支撐軸263被傳遞至行 星齒輪280。而且，行星齒輪280與設置在帶恆星齒輪的平衡塊支架320上的恆星齒輪323和設置在殼體10A內部的內周齒輪115相互嚙合。因此，透過被施加由小齒輪50引起的旋轉，行星齒輪280能夠在恆星齒輪323和內周齒輪115之間所形成的空間內以內齒輪261的中心部為中心進行公轉。 Next, the relative positions of the components in the assembled state will be described in more detail using FIGS. 16 and 17. Fig. 16 is a cross-sectional view of a cut portion taken along the line A-A in Fig. 4(c). As shown in FIG. 16, the pinion gear 50 centered on the shaft core 31 and the internal gear 261 provided on the gear carrier 260 with internal teeth mesh with each other. In addition, it is configured that the rotation of the internal gear 261 is transmitted to the row via the support shaft 263 of the gear carrier 260 with internal teeth. Star gear 280. Furthermore, the planetary gear 280 meshes with the sun gear 323 provided on the balance weight bracket 320 with sun gear and the inner peripheral gear 115 provided inside the housing 10A. Therefore, by applying the rotation caused by the pinion gear 50, the planetary gear 280 can revolve around the center of the internal gear 261 in the space formed between the sun gear 323 and the internal peripheral gear 115.

圖17是圖5(a)的B-B線切斷部之剖視圖。如圖17所示，在本實施方式中，B-B線切斷部的剖視圖以安裝筒702為中心形成為大致左右對稱。而且，軸芯31和軸芯41從殼體10A的上端和基座70的下端突出。另外，在本實施方式中，第一導向壁16A和第二導向壁17A的上端分別與軸芯31和軸芯41的上端為大致相同的高度。 Fig. 17 is a cross-sectional view of a cut portion taken along line B-B in Fig. 5(a). As shown in Fig. 17, in the present embodiment, the cross-sectional view of the cut portion along the line B-B is formed to be approximately bilaterally symmetrical with the mounting cylinder 702 as the center. Furthermore, the shaft core 31 and the shaft core 41 protrude from the upper end of the housing 10A and the lower end of the base 70. In addition, in the present embodiment, the upper ends of the first guide wall 16A and the second guide wall 17A are substantially the same height as the upper ends of the shaft core 31 and the shaft core 41, respectively.

而且，滾花輥240和輥部42位於滑塊220的內部。進而，小齒輪50在與滾花輥240一同夾持著滑塊220的狀態下位於滑塊220的外部。另外，小齒輪50與內齒輪261相互嚙合。 Furthermore, the knurling roller 240 and the roller portion 42 are located inside the slider 220. Furthermore, the pinion gear 50 is located outside the slider 220 in a state in which the slider 220 is clamped together with the knurled roller 240. In addition, the pinion gear 50 and the internal gear 261 mesh with each other.

而且，殼體10A的上側至凸緣部13被排列部件200覆蓋。另外，殼體10A在其下端與基座70卡合。而且，在基座70的上部保持有平衡塊340。在此，在本實施方式中，由於平衡塊340形成為裝卸式，因此能夠利用平衡塊340的數量和種類調整需要的制動力。亦即，在需要大制動力之情形下，可以增加平衡塊340的數量，或在帶恆星齒輪的平衡塊支架320上保持其他的密度更大的平衡塊。另一方面，在小的制動力就足夠之情形下，可以減少平衡塊340的數量。另外，從旋轉時的穩定性之觀點出發，較佳在帶恆星齒輪的平衡塊支架320進行保持的面上呈對稱地配置平衡塊340。另外，在本實施方式中，透過設置在平衡塊340上的突起341與基座70的底面抵接，從而能夠減小旋轉時的平衡塊340與基座70之間的阻力。 Furthermore, the upper side of the housing 10A to the flange portion 13 are covered by the arrangement member 200. In addition, the housing 10A is engaged with the base 70 at its lower end. Furthermore, a balance weight 340 is held on the upper part of the base 70. Here, in the present embodiment, since the balance weight 340 is formed as a removable type, the number and type of the balance weight 340 can be used to adjust the required braking force. That is, when a large braking force is required, the number of balance weights 340 can be increased, or other balance weights with higher density can be maintained on the balance weight support 320 with sun gear. On the other hand, in the case where a small braking force is sufficient, the number of balance weights 340 can be reduced. In addition, from the viewpoint of stability during rotation, it is preferable to arrange the balance weights 340 symmetrically on the surface held by the balance weight holder 320 with the sun gear. In addition, in the present embodiment, the protrusion 341 provided on the weight 340 abuts against the bottom surface of the base 70, so that the resistance between the weight 340 and the base 70 during rotation can be reduced.

接著，利用圖18對本實施方式之制動裝置1000之動作進行說明。圖18(a)是未對繩CD施加任何張力的狀態(正常狀態)，圖18(b)是對繩CD施加張力、且以滾花輥240和輥部42夾持繩CD的狀態(夾持狀態)，圖18(c)是從圖18(a)的狀態向圖18(b)的狀態變化時的各部件的旋轉方向之總結圖。另外，圖18(a)、(b)與圖16相同，都是圖4(c)的A-A線切斷部之剖視圖。在此，出於說明上的原因，將該剖視圖中未顯示的輥部42的外周重疊於軸芯41的周圍而表示、滾花輥240的外周重疊於軸芯31的周圍而表示。另外，滾花輥240的外周並不是嚴格的圓形，但是為了說明的簡化以近似於圓形進行圖示。 Next, the operation of the brake device 1000 of this embodiment will be described with reference to FIG. 18. Fig. 18(a) is a state where no tension is applied to the rope CD (normal state), and Fig. 18(b) is a state in which tension is applied to the rope CD and the rope CD is clamped by the knurling roller 240 and the roller 42 (clamping Holding state), Fig. 18(c) is a summary view of the rotation direction of each member when changing from the state of Fig. 18(a) to the state of Fig. 18(b). 18(a) and (b) are the same as FIG. 16, and both are cross-sectional views taken along the line A-A of FIG. 4(c). Here, for descriptive reasons, the outer circumference of the roller portion 42 not shown in the cross-sectional view is superimposed on the circumference of the shaft core 41, and the outer circumference of the knurled roller 240 is superimposed on the circumference of the shaft core 31. In addition, the outer periphery of the knurling roller 240 is not strictly circular, but for the sake of simplification of description, it is shown as an approximate circular shape.

如圖18(a)所示，在正常狀態下，如上所述，螺旋彈簧SP與殼體10A的後方的內壁抵接，將滑塊220向前方推壓。因此，滑塊220位於殼體10A的前方。藉此，藉由滑塊220的第一頂壁槽226和第一底壁槽228而被限制了位置的軸芯31以及藉由第二頂壁槽227和第二底壁槽229而被限制了位置的軸芯41，與滑塊220一同向前方移動。進而，被保持於滑塊220上部的殼體10A中所設置的第一頂壁槽16和第二頂壁槽17，隨著朝向前方而相互之間的距離變小。同樣地，基座70中所設置的第一基座槽706和第二基座槽707，隨著朝向前方而相互之間的距離變小。因此，以能夠旋轉之方式支撐於軸芯41的輥部42和以能夠旋轉之方式支撐於軸芯31的滾花輥240之間的距離也變小。亦即，第一頂壁槽16和第一基座槽706作為限制槽發揮作用，該限制槽與滾花輥240的軸芯31呈能夠移動地嵌合從而限制滾花輥240只能沿槽進行移動。同樣地，第二頂壁槽17和第二基座槽707作為限制槽發揮作用，該限制槽與輥部42的軸芯41呈能夠移動地嵌合從而限制輥部42只能沿槽進行移動。另外，由於俯視時第一頂壁槽16和第一基座槽706與帶內齒的齒輪架260的內周面的中心點形成在同心圓上，因此，即使軸芯31在各個槽內移動，小齒輪50也能夠持續與設置在帶內齒的齒輪架260上的內齒輪261嚙合。 As shown in FIG. 18(a), in the normal state, as described above, the coil spring SP abuts against the inner wall of the housing 10A and pushes the slider 220 forward. Therefore, the slider 220 is located in front of the housing 10A. Thereby, the shaft core 31 whose position is restricted by the first top wall groove 226 and the first bottom wall groove 228 of the slider 220 is restricted by the second top wall groove 227 and the second bottom wall groove 229 The shaft core 41, which has been in position, moves forward together with the slider 220. Furthermore, the first ceiling wall groove 16 and the second ceiling wall groove 17 provided in the housing 10A held on the upper portion of the slider 220 decrease in distance between each other as they go to the front. Similarly, the first susceptor groove 706 and the second susceptor groove 707 provided in the susceptor 70 decrease the distance between each other as they go to the front. Therefore, the distance between the roller part 42 rotatably supported by the shaft core 41 and the knurled roller 240 rotatably supported by the shaft core 31 is also reduced. That is, the first top wall groove 16 and the first base groove 706 function as restricting grooves, which are movably fitted with the shaft core 31 of the knurled roller 240 to restrict the knurled roller 240 to only move along the groove. Make a move. Similarly, the second top wall groove 17 and the second base groove 707 function as restriction grooves that are movably fitted with the shaft core 41 of the roller portion 42 to restrict the roller portion 42 from only moving along the groove. . In addition, since the center points of the first top wall groove 16 and the first base groove 706 and the inner peripheral surface of the gear carrier 260 with internal teeth are formed on concentric circles when viewed from above, even if the shaft core 31 moves in each groove , The pinion gear 50 can also continuously mesh with the internal gear 261 provided on the gear carrier 260 with internal teeth.

如此，當滾花輥240和輥部42之間的距離變小時，滾花輥240被輥部42推壓，繩CD被滾花輥240和輥部42夾持。亦即，在本實施方式中，螺旋彈簧SP也作為始終對滾花輥240施加作用力的施力部件發揮作用，以使滾花輥240被輥部42推壓。 In this way, when the distance between the knurling roller 240 and the roller portion 42 becomes smaller, the knurling roller 240 is pushed by the roller portion 42 and the cord CD is clamped by the knurling roller 240 and the roller portion 42. That is, in the present embodiment, the coil spring SP also functions as an urging member that always applies a force to the knurled roller 240 so that the knurled roller 240 is pressed by the roller portion 42.

而且，在正常狀態的制動裝置1000中，對繩CD朝向箭頭D1的方向(前方)施加張力。於是，利用與繩CD之間產生的摩擦力，滾花輥240進行逆時針旋轉，輥部42進行順時針旋轉。接著，透過滾花輥240的旋轉，與其共有相同的軸芯31而被固定的小齒輪50也朝向與滾花輥240相同的方向(逆時針)旋轉(自轉)。此時，如圖18(b)所示，軸芯31和軸芯41俯視時朝向前方移動，且在左右方向上相互靠近，滾花輥240和輥部42對繩CD的夾持力變強，從而根據繩CD的移動而滾花輥240可靠地進行旋轉。於是，由於小齒輪50與內齒輪261嚙合，因此，利用由小齒輪50的齒施加的力，內齒輪261進行逆時針旋轉(自轉)。藉此，由於帶內齒的齒輪架260也與內齒輪261一起進行逆時針旋轉(自轉)，因此，設置在帶內齒的齒輪架260上的行星齒輪280也同樣地進行逆時針旋轉(公轉)。在此，由於行星齒輪280與由恆星齒輪323和殼體10A固定的內周齒輪115相互嚙合，因此，變為朝向與公轉方向相反的方向(順時針)自轉，同時以逆時針公轉。因此，在行星齒輪280的內側與行星齒輪280嚙合的恆星齒輪323朝向與行星齒輪280的自轉相反的方向(逆時針)旋轉(自轉)。此時，利用行星齒輪280，恆星齒輪323的旋轉被增速。藉此，與恆星齒輪323一同旋轉的帶恆星齒輪的平衡塊支架320上所保持的平衡塊340也開始旋轉。另外，如已述那樣，在行星齒輪280的外側與行星齒輪280嚙合的內周齒輪115由於殼體10A和基座70被固定，因此，即使在行星齒輪280旋轉時，內周齒輪115也不會旋轉。 In addition, in the braking device 1000 in the normal state, tension is applied to the cord CD in the direction of the arrow D1 (forward). Then, the knurling roller 240 rotates counterclockwise, and the roller portion 42 rotates clockwise using the friction force generated with the cord CD. Next, through the rotation of the knurled roller 240, the pinion gear 50, which shares the same shaft core 31 and is fixed, also rotates (rotates) in the same direction (counterclockwise) as the knurled roller 240. At this time, as shown in FIG. 18(b), the shaft core 31 and the shaft core 41 move forward in a plan view and are close to each other in the left and right directions, and the gripping force of the knurled roller 240 and the roller portion 42 on the cord CD becomes stronger. Therefore, the knurling roller 240 reliably rotates in accordance with the movement of the cord CD. Then, since the pinion gear 50 meshes with the internal gear 261, the internal gear 261 rotates counterclockwise (rotates) by the force applied by the teeth of the pinion gear 50. Thereby, since the gear carrier 260 with internal teeth also rotates counterclockwise (rotation) together with the internal gear 261, the planetary gear 280 provided on the gear carrier 260 with internal teeth also rotates counterclockwise (revolution). ). Here, since the planetary gear 280 meshes with the inner peripheral gear 115 fixed by the sun gear 323 and the housing 10A, the planetary gear 280 rotates in a direction opposite to the revolution direction (clockwise) while revolving counterclockwise. Therefore, the sun gear 323 meshed with the planetary gear 280 inside the planetary gear 280 rotates (rotates) in the direction opposite to the rotation of the planetary gear 280 (counterclockwise). At this time, with the planetary gear 280, the rotation of the sun gear 323 is accelerated. Thereby, the balance weight 340 held on the balance weight support 320 with sun gear that rotates together with the sun gear 323 also starts to rotate. In addition, as described above, since the housing 10A and the base 70 are fixed to the inner gear 115 that meshes with the planetary gear 280 on the outer side of the planetary gear 280, the inner gear 115 does not change even when the planetary gear 280 rotates. Will rotate.

而且，如圖18(b)所示，當滾花輥240和輥部42靠近至邊界(夾持狀態)時，滾花輥240繼續自轉，但滾花輥240的沿內齒輪261的移動停止。此時， 由滾花輥240的自轉引起的其他部件的旋轉還在繼續。於是，平衡塊340利用離心力與殼體10A的內周壁抵接，藉此對旋轉產生阻力。亦即，藉由繩CD的移動速度上昇而使得轉速上昇，藉此離心力增大。而且，透過離心力增大，平衡塊340與殼體10A的內周壁更強力地抵接，從而阻力增大。藉此，能夠抑制繩CD的移動速度(日射遮蔽部件的下降速度)。在此，在對繩CD施加的張力為大致固定的情況(例如，在制動裝置1000的前方側的繩CD上以能夠昇降之方式被懸掛支撐的日射遮蔽部件自由落體之情況)下，當對繩CD施加的張力與由平衡塊340和殼體10A的內周壁產生的阻力相平衡時，繩CD的移動速度變為大致固定。因此，制動裝置1000作為針對繩CD的移動的旋轉阻尼器發揮作用，能夠使日射遮蔽部件緩慢地下降。 Furthermore, as shown in FIG. 18(b), when the knurling roller 240 and the roller portion 42 are close to the boundary (nip state), the knurling roller 240 continues to rotate, but the movement of the knurling roller 240 along the internal gear 261 stops . at this time, The rotation of other components caused by the rotation of the knurling roller 240 continues. Then, the balance weight 340 abuts against the inner peripheral wall of the housing 10A by centrifugal force, thereby generating resistance to rotation. That is, as the moving speed of the rope CD increases, the rotation speed increases, thereby increasing the centrifugal force. Furthermore, as the centrifugal force increases, the weight 340 abuts against the inner peripheral wall of the housing 10A more strongly, and the resistance increases. Thereby, the moving speed of the cord CD (the descending speed of the solar radiation shielding member) can be suppressed. Here, in the case where the tension applied to the rope CD is substantially constant (for example, in the case where the solar shielding member that is suspended and supported on the rope CD on the front side of the brake device 1000 freely falls), the When the tension applied by the rope CD is balanced with the resistance generated by the balance weight 340 and the inner peripheral wall of the housing 10A, the moving speed of the rope CD becomes substantially constant. Therefore, the braking device 1000 functions as a rotary damper for the movement of the cord CD, and can lower the solar radiation shielding member slowly.

圖18(c)是針對以上所說明的從正常狀態向夾持狀態的夾持狀態變化總結了各部件的旋轉方向(關於小齒輪50，進而還包括俯視時的前後方向和緊固方向)的圖。 Figure 18(c) summarizes the rotation direction of each component (for the pinion gear 50, it also includes the front and rear direction and the tightening direction when viewed from the top) for the change in the clamping state from the normal state to the clamping state described above Figure.

另一方面，在對繩CD朝向與箭頭D1相反的方向(後方)施加張力之情形下，滾花輥240和輥部42朝向與上述相反的方向旋轉。其結果是，軸芯31和軸芯41以沿著第一頂壁槽16和第二頂壁槽17相互遠離之方式移動。於是，滾花輥240對繩CD的夾持力變弱，能夠以較弱的力拉拽繩CD。因此，在上樑內設置制動裝置1000之情形下，較佳在圖18中將向前方對繩CD施加張力的方向作為日射遮蔽部件的下降方向、向後方對繩CD施加張力的方向作為日射遮蔽部件的上昇方向。 On the other hand, when tension is applied to the cord CD in the direction opposite to the arrow D1 (rear), the knurled roller 240 and the roller portion 42 rotate in the opposite direction to the above. As a result, the shaft core 31 and the shaft core 41 move away from each other along the first ceiling wall groove 16 and the second ceiling wall groove 17. Then, the clamping force of the knurled roller 240 with respect to the cord CD becomes weak, and the cord CD can be pulled with a weak force. Therefore, in the case where the brake device 1000 is installed in the upper beam, it is preferable to set the direction in which tension is applied to the rope CD forward as the descending direction of the solar shielding member, and the direction in which tension is applied to the rope CD backward as the solar shield in FIG. The rising direction of the part.

接著，利用圖19對正常狀態和夾持狀態的狀態變化時的滑塊220的移動進行說明。圖19(a)與圖18(a)、圖19(b)與圖18(b)分別對應。 Next, the movement of the slider 220 when the state changes between the normal state and the gripping state will be described with reference to FIG. 19. Fig. 19(a) corresponds to Fig. 18(a), and Fig. 19(b) and Fig. 18(b) respectively.

從圖19(a)的正常狀態向圖19(b)的夾持狀態變化時，軸芯41和輥部42以及軸芯31和滾花輥240，利用與繩CD的摩擦力向圖中的前方移動。此 時，透過軸芯41與第二頂壁槽227和第二底壁槽229抵接，隨著軸芯41朝向前方的移動，對第二頂壁槽227和第二底壁槽229朝向前方施力。另外，透過軸芯31與第一頂壁槽226和第一底壁槽228抵接，隨著軸芯31朝向前方的移動，對第一頂壁槽226和第一底壁槽228朝向前方施力。因此，當軸芯31、41向前方移動△時，滑塊220也向前方移動△。 When changing from the normal state of FIG. 19(a) to the gripping state of FIG. 19(b), the shaft core 41 and the roller portion 42, as well as the shaft core 31 and the knurled roller 240, use the frictional force with the cord CD to move toward the center of the figure. Move forward. this When the shaft core 41 is in contact with the second top wall groove 227 and the second bottom wall groove 229, as the shaft core 41 moves forward, the second top wall groove 227 and the second bottom wall groove 229 are applied to the front. force. In addition, the shaft core 31 is in contact with the first top wall groove 226 and the first bottom wall groove 228, and as the shaft core 31 moves forward, the first top wall groove 226 and the first bottom wall groove 228 are applied forward. force. Therefore, when the shaft cores 31 and 41 move forward by Δ, the slider 220 also moves forward by Δ.

接著，利用圖20對一對夾持部件(輥部42和滾花輥240)的初始狀態(磨損前)的規定夾持位置和磨損後的夾持位置進行說明。另外，在本實施方式中，輥部42和滾花輥240分別是以軸41和軸31為中心進行旋轉的旋轉體。 Next, the predetermined nipping position of the initial state (before abrasion) and the nipping position after the abrasion of the pair of nip members (the roller portion 42 and the knurled roller 240) will be described with reference to FIG. 20. In addition, in the present embodiment, the roller portion 42 and the knurled roller 240 are rotating bodies that rotate around the shaft 41 and the shaft 31, respectively.

如圖20所示，在滾花輥240的初始狀態、即因磨損而直徑變小前的狀態下，伴隨著繩CD的移動，滾花輥240和輥部42從釋放(解除夾持)位置沿第一頂壁槽16和第二頂壁槽17向前方移動。亦即，一對夾持體的至少一方構成為以規定的移動軌跡(圖中的雙箭頭)進行移動。在此，該移動軌跡可以說是沿著限制槽(第一頂壁槽16和第一基座槽706、以及第二頂壁槽17和第二基座槽707(參照圖5))的夾持體的移動軌跡。藉此，滾花輥240和輥部42夾持繩CD。此時的滾花輥240和輥部42的位置是規定的夾持位置。 As shown in FIG. 20, in the initial state of the knurled roller 240, that is, in the state before the diameter becomes smaller due to wear, the knurled roller 240 and the roller portion 42 move from the release (un-nip) position along with the movement of the cord CD. Move forward along the first top wall groove 16 and the second top wall groove 17. That is, at least one of the pair of clamping bodies is configured to move along a predetermined movement trajectory (double arrow in the figure). Here, the movement trajectory can be said to be a clamp along the restriction grooves (the first top wall groove 16 and the first base groove 706, and the second top wall groove 17 and the second base groove 707 (refer to FIG. 5)). The movement trajectory of the holding body. Thereby, the knurling roller 240 and the roller part 42 clamp the cord CD. The positions of the knurling roller 240 and the roller portion 42 at this time are the predetermined nipping positions.

此時，移動軌跡超過規定的夾持位置而延伸。換言之，限制槽超過該夾持位置而延伸。進而，移動軌跡在朝向繩CD的方向上延伸。而且，滾花輥240和輥部42的移動軌跡以其延長線相互交叉之方式構成。另外，該夾持位置是從限制槽的相對於繩CD的靠近方向側(圖20中的前側)的端部遠離之位置。而且，滾花輥240或輥部42的一部分、尤其是與繩CD的接觸部因磨損而削減，滾花輥240或輥部42的直徑變小之情形下，透過在限制槽的超過規定夾持位置(初始狀態下的夾持位置)的範圍內將軸31和軸41保持於限制槽內，藉此滾花輥240和輥部42夾持繩CD。如圖20所示，磨損後的夾持位置位於僅比規定的夾持位置朝向圖中的前方移動了d的位置。 At this time, the movement trajectory extends beyond the predetermined clamping position. In other words, the restriction groove extends beyond the clamping position. Furthermore, the movement trajectory extends in the direction toward the cord CD. Moreover, the movement trajectory of the knurling roller 240 and the roller part 42 is comprised so that the extension line may cross each other. In addition, the clamping position is a position away from the end of the restriction groove on the approaching direction side (the front side in FIG. 20) with respect to the cord CD. Furthermore, a part of the knurled roller 240 or the roller 42, especially the contact part with the cord CD is reduced due to wear. When the diameter of the knurled roller 240 or the roller 42 becomes smaller, it passes through the restriction groove exceeding the prescribed clamp The shaft 31 and the shaft 41 are held in the restricting groove within the range of the holding position (the holding position in the initial state), whereby the knurled roller 240 and the roller portion 42 clamp the cord CD. As shown in FIG. 20, the clamping position after abrasion is located at a position shifted by d from the predetermined clamping position toward the front in the figure.

如此，透過移動軌跡(限制槽)超過滾花輥240或輥部42的初始狀態下的夾持位置而延伸，即使在滾花輥240或輥部42的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, the movement trajectory (restriction groove) extends beyond the nip position of the knurled roller 240 or the roller portion 42 in the initial state, even if the diameter of the knurled roller 240 or the roller portion 42 becomes smaller due to wear, The cord CD can also be clamped appropriately.

另外，即使在繩直徑因繩的磨損而變細之情形下，也能夠發揮同樣的效果。 In addition, the same effect can be exerted even when the diameter of the rope becomes thin due to the abrasion of the rope.

2.第二實施方式 2. The second embodiment

接下來，利用圖21~圖23對本發明第二實施方式之運動轉換部進行說明。如圖21所示，在第二實施方式中，滾花輥240和輥部42分別經由軸芯31和軸芯41而被連接。在此，該連接方法為任意方法，例如圖21(a)所示，亦可使用一對板片800。在此，在第二實施方式中，板片800為大致矩形，例如能夠使用金屬制的板片800。另外，在板片800的與軸芯31和軸芯41對應的位置處設置有貫通孔801，透過將軸芯31和軸芯41***貫通孔801中，從而能夠將滾花輥240和輥部42連接。另外，使用繩狀部件900之情形下，如圖22所示，由於繩CD移動時滾花輥240和輥部42朝向相反的方向旋轉，因此形成為將繩狀部件900交叉的構成。在此，圖22是從箭頭Z方向觀察圖21(b)的部件夾持繩CD的狀態之模式圖。 Next, the motion conversion unit of the second embodiment of the present invention will be described using FIGS. 21 to 23. As shown in FIG. 21, in the second embodiment, the knurled roller 240 and the roller portion 42 are connected via the shaft core 31 and the shaft core 41, respectively. Here, the connection method is any method. For example, as shown in FIG. 21(a), a pair of plates 800 may also be used. Here, in the second embodiment, the plate piece 800 is substantially rectangular, and for example, a metal plate piece 800 can be used. In addition, a through hole 801 is provided at the position of the plate 800 corresponding to the shaft core 31 and the shaft core 41. By inserting the shaft core 31 and the shaft core 41 into the through hole 801, the knurled roller 240 and the roller can be connected. 42 connections. In addition, in the case of using the cord-shaped member 900, as shown in FIG. 22, the knurled roller 240 and the roller 42 rotate in opposite directions when the cord CD moves, so the cord-shaped member 900 is crossed. Here, FIG. 22 is a schematic view of the state in which the member of FIG. 21(b) clamps the cord CD when viewed from the arrow Z direction.

另外，如圖21(b)所示，亦可代替板片800而使用繩狀部件900將滾花輥240和輥部42連接。 In addition, as shown in FIG. 21(b), instead of the sheet 800, a cord-shaped member 900 may be used to connect the knurled roller 240 and the roller portion 42.

接著，如圖23所示，該部件在殼體10B的內部以將繩CD夾持於滾花輥240和輥部42之間之方式設置。在此，在圖23中，為了提高可見性，使用圖21(b)中之利用繩狀部件900的形態進行說明。另外，設為重力g作用於圖23的箭頭g所表示的方向。為了方便說明，將箭頭g的方向作為下方，將與箭頭g相反的方向作為上方。 Next, as shown in FIG. 23, this member is installed in the inside of the housing 10B so that the cord CD may be clamped between the knurling roller 240 and the roller part 42. As shown in FIG. Here, in FIG. 23, in order to improve visibility, the form using the rope-shaped member 900 in FIG. 21(b) is used for description. In addition, it is assumed that gravity g acts in the direction indicated by arrow g in FIG. 23. For convenience of description, the direction of arrow g is referred to as downward, and the direction opposite to arrow g is referred to as upward.

另外，在殼體10B中，在與軸芯31對應的位置處設置有第一側壁孔119A。第一側壁孔119A是朝向前方傾斜的長圓形。另外，該等形狀沒有特別限 定，可以適當設計。在此，在第二實施方式中，第一側壁孔119A相當於限制槽，且超過第一夾持部件(滾花輥240)的初始狀態下的夾持位置而延伸。另外，在圖23(b)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。另外，圖23(b)中的雙箭頭表示夾持體的移動軌跡。 In addition, in the housing 10B, a first side wall hole 119A is provided at a position corresponding to the shaft core 31. The first side wall hole 119A has an oblong shape inclined toward the front. In addition, these shapes are not particularly limited It can be designed appropriately. Here, in the second embodiment, the first side wall hole 119A corresponds to the restriction groove, and extends beyond the nipping position of the first nipping member (knurled roller 240) in the initial state. In addition, in FIG. 23(b), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn. In addition, the double arrow in FIG. 23(b) indicates the movement trajectory of the holder.

軸芯31能夠沿第一側壁孔119A移動。在此，滾花輥240是設置在能夠與繩CD接觸的位置且能夠沿垂直方向移動的輥。在此，在第一側壁孔119A中，由夾持導向斜面119a、釋放導向斜面119b、夾持側限制面119c以及釋放側限制面119d形成內周面。 The shaft core 31 can move along the first side wall hole 119A. Here, the knurling roller 240 is a roller that is provided at a position capable of contacting the cord CD and capable of moving in the vertical direction. Here, in the first side wall hole 119A, an inner peripheral surface is formed by the clamping guide slope 119a, the release guide slope 119b, the clamping side restriction surface 119c, and the release side restriction surface 119d.

另外，在殼體10B的內部，在挾著繩CD與滾花輥240相對且比滾花輥240更靠前方的位置上固定有支柱92。 In addition, in the inside of the housing 10B, a pillar 92 is fixed at a position that faces the knurled roller 240 with the cord CD interposed therebetween, and is further forward than the knurled roller 240.

首先，當從圖23(a)所示的狀態對繩CD朝向箭頭D2方向施加張力時，利用與繩CD之間產生的摩擦力，滾花輥240朝向箭頭D3的方向沿第一側壁孔119A向下方移動。此時，滾花輥240的移動軌跡是沿著第一側壁孔119A的軌跡。另外，如圖23(b)所示，移動軌跡超過規定的夾持位置而延伸。 First, when tension is applied to the rope CD in the direction of arrow D2 from the state shown in FIG. 23(a), the frictional force generated with the rope CD causes the knurling roller 240 to move in the direction of arrow D3 along the first side wall hole 119A. Move down. At this time, the movement trajectory of the knurling roller 240 is along the trajectory of the first side wall hole 119A. In addition, as shown in FIG. 23(b), the movement trajectory extends beyond the predetermined clamping position.

如圖23(b)所示，將該位置作為具有垂直成分的可動方向的下側的位置、亦即第一位置。該狀態下，由於滾花輥240與支柱92在垂直方向上的距離小，因此繩CD彎曲，變成夾持狀態。亦即，支柱92作為與滾花輥240夾著繩CD而定位的第二夾持部件發揮作用。另外，輥部42作為與滾花輥240聯動而進行移動的輔助輥發揮作用。 As shown in FIG. 23(b), this position is a position on the lower side of the movable direction having a vertical component, that is, the first position. In this state, since the distance between the knurled roller 240 and the support 92 in the vertical direction is small, the cord CD bends and becomes a clamped state. That is, the pillar 92 functions as a second nipping member that is positioned to sandwich the cord CD with the knurled roller 240. In addition, the roller portion 42 functions as an auxiliary roller that moves in conjunction with the knurling roller 240.

在此，在夾持狀態下，當軸芯31到達可動範圍的前方界限時，呈大致平行移動的滾花輥240開始旋轉(圖中的順時針)。接著，與第三實施方式同樣地，亦可將軸芯31的旋轉輸出至伴隨著繩CD的移動而產生阻力之阻力賦予部RA。此時，亦可在滾花輥240或滾花輥240與阻力賦予部RA之間設置單向離合器，以使當繩CD向前方移動時旋轉被傳遞給阻力賦予部RA，但當繩CD向後方移 動時旋轉不會被傳遞給阻力賦予部RA。在此，阻力賦予部RA亦可設置在殼體10B的內部或外部，亦可設置在滾花輥240內部。 Here, in the clamping state, when the shaft core 31 reaches the front limit of the movable range, the knurling roller 240 that moves substantially in parallel starts to rotate (clockwise in the figure). Next, similarly to the third embodiment, the rotation of the shaft core 31 may be output to the resistance imparting portion RA that generates resistance along with the movement of the cord CD. At this time, a one-way clutch may be provided between the knurled roller 240 or the knurled roller 240 and the resistance imparting part RA so that when the rope CD moves forward, the rotation is transmitted to the resistance imparting part RA, but when the rope CD moves forward Move back The rotation during movement is not transmitted to the resistance imparting part RA. Here, the resistance imparting portion RA may be provided inside or outside the housing 10B, or may be provided inside the knurling roller 240.

另一方面，當對繩CD朝向與箭頭D2相反的方向施加張力時，透過產生與上述動作相反方向的動作，滾花輥240與支柱92在垂直方向上的距離變遠，從而對繩CD的夾持力變弱。 On the other hand, when tension is applied to the rope CD in the direction opposite to the arrow D2, the vertical distance between the knurling roller 240 and the support 92 becomes longer by generating a motion in the opposite direction to the above-mentioned motion, and the rope CD is The clamping force becomes weaker.

接著，如圖23(a)所示，軸芯31反抗重力g，而向第一側壁孔119A的具有垂直成分的可動方向(圖23中的傾斜方向)的上側的位置、亦即第二位置移動。將該狀態稱為自由移動狀態。在自由移動狀態下，繩CD以非彎曲狀態被釋放。然後，能夠允許繩CD的自由移動。 Next, as shown in FIG. 23(a), the shaft core 31 opposes the gravity g and moves toward the second position, which is the position above the vertical component of the movable direction (the tilt direction in FIG. 23) of the first side wall hole 119A mobile. This state is called a free movement state. In the freely moving state, the cord CD is released in a non-bent state. Then, the free movement of the cord CD can be allowed.

另外，也能夠取代軸芯31和滾花輥240以及軸芯41和輥部42，而使用不旋轉的支柱。 In addition, instead of the shaft core 31 and the knurled roller 240, and the shaft core 41 and the roller portion 42, it is also possible to use a pillar that does not rotate.

如此，在第二實施方式中，透過移動軌跡(限制槽)超過滾花輥240或輥部42的初始狀態下的夾持位置而延伸，從而即使在滾花輥240或輥部42的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, in the second embodiment, the movement trajectory (restriction groove) extends beyond the nip position of the knurled roller 240 or the roller portion 42 in the initial state, so that even if the diameter of the knurled roller 240 or the roller portion 42 is affected by Even when it becomes smaller due to wear, the cord CD can be clamped appropriately.

3.第三實施方式 3. The third embodiment

接著，利用圖24對本發明第三實施方式之其他運動轉換部進行說明。如圖24所示，在第三實施方式之殼體10C中形成比滾花輥240的直徑稍大的收納空間93。在此，收納空間93剖視時呈將圓弧形狀和射線形狀組合後的形狀。因此，滾花輥240能夠在收納空間93內自由地移動。另外，收納空間93中形成有夾持導向斜面93a和釋放側限制面93d。 Next, another motion conversion unit of the third embodiment of the present invention will be described using FIG. 24. As shown in FIG. 24, a housing space 93 slightly larger than the diameter of the knurled roller 240 is formed in the housing 10C of the third embodiment. Here, the storage space 93 has a shape in which a circular arc shape and a ray shape are combined in a cross-sectional view. Therefore, the knurled roller 240 can move freely in the storage space 93. In addition, a clamping guide slope 93a and a release side restriction surface 93d are formed in the storage space 93.

而且，在殼體10C的內部配置有軸芯31、滾花輥240、支柱92、兩根輸出軸95以及環形帶94。另外，在殼體10C中與軸芯31對應的位置處設置有第一側壁孔119A。在此，在第三實施方式中，第一側壁孔119A相當於限制槽，且超過第一夾持部件(滾花輥240)的初始狀態下的夾持位置而延伸。另外，圖24 (b)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。另外，圖24(b)中的雙箭頭表示夾持體的移動軌跡。在此，滾花輥240設置成在自由移動狀態下與繩CD稍微接觸。 In addition, the shaft core 31, the knurling roller 240, the support column 92, the two output shafts 95, and the endless belt 94 are arranged inside the housing 10C. In addition, a first side wall hole 119A is provided at a position corresponding to the shaft core 31 in the housing 10C. Here, in the third embodiment, the first side wall hole 119A corresponds to the restriction groove, and extends beyond the nipping position of the first nipping member (knurled roller 240) in the initial state. In addition, Figure 24 In (b), the dashed circle indicates the predetermined clamping position, and the following description is to describe the operation after the clamping body is worn. In addition, the double arrow in FIG. 24(b) indicates the movement trajectory of the holder. Here, the knurling roller 240 is arranged to slightly contact the cord CD in a freely moving state.

滾花輥240以與支柱92之間夾持繩CD之方式設置。而且，在兩根輸出軸95上架有環形帶94。環形帶94係構成為：藉由滾花輥240的旋轉對環形帶94作用阻力，從而環形帶94能夠旋轉。另外，可能的話，環形帶94的表面亦可形成為與滾花輥240及輸出軸95的表面嚙合那樣的形狀。另外，輸出軸95係構成為將自身的旋轉輸出至伴隨著繩CD的移動而產生阻力之阻力賦予部。輸出軸95和環形帶94以環形帶94與收納空間93的射線部分呈大致直線的方式構成。 The knurling roller 240 is installed so as to sandwich the cord CD with the pillar 92. Furthermore, an endless belt 94 is mounted on the two output shafts 95. The endless belt 94 is configured such that resistance is applied to the endless belt 94 by the rotation of the knurled roller 240, so that the endless belt 94 can rotate. In addition, if possible, the surface of the endless belt 94 may be formed into a shape that meshes with the surfaces of the knurling roller 240 and the output shaft 95. In addition, the output shaft 95 is configured to output its own rotation to a resistance imparting portion that generates resistance along with the movement of the cord CD. The output shaft 95 and the endless belt 94 are configured such that the endless belt 94 and the ray portion of the storage space 93 are substantially straight.

首先，當從圖24(a)所示之狀態對繩CD朝向箭頭D4方向施加張力時，利用與繩CD之間產生的摩擦力，滾花輥240朝向箭頭D5的方向旋轉，同時經過收納空間93的射線部分朝向靠近環形帶94的方向移動(第一位置)。此時，滾花輥240的移動軌跡是沿著第一側壁孔119A的軌跡。另外，如圖24(b)所示，移動軌跡超過規定的夾持位置而延伸。如圖24(b)所示，在該狀態下，由於滾花輥240與支柱92在垂直方向上的距離小，因此繩CD彎曲，變成夾持狀態。即，支柱92作為與滾花輥240夾著繩CD而定位的第二夾持部件發揮作用。 First, when tension is applied to the rope CD in the direction of arrow D4 from the state shown in FIG. 24(a), the friction force generated between the rope CD and the knurling roller 240 rotates in the direction of arrow D5 while passing through the storage space. The ray portion of 93 moves toward the direction approaching the endless belt 94 (first position). At this time, the movement trajectory of the knurling roller 240 is along the trajectory of the first side wall hole 119A. In addition, as shown in FIG. 24(b), the movement trajectory extends beyond the predetermined clamping position. As shown in FIG. 24(b), in this state, since the distance between the knurling roller 240 and the support 92 in the vertical direction is small, the cord CD bends and becomes a clamped state. In other words, the support post 92 functions as a second nipping member that is positioned to sandwich the cord CD with the knurled roller 240.

另外，在夾持狀態下，亦可將輸出軸95的旋轉輸出至阻力賦予部RA。亦即，利用作用於滾花輥240和環形帶94之間的摩擦力，環形帶94相對於輸出軸95朝向與箭頭D5相反的方向(逆時針)旋轉。藉此，輸出軸95也朝向與環形帶94相同的方向(逆時針)旋轉(自轉)。該旋轉輸出至阻力賦予部RA。在該構成中，輸出軸95中的一者發揮與第二實施方式中的軸芯31相同的作用(向阻力賦予部RA傳遞旋轉)。此時，亦可在滾花輥240與阻力賦予部RA之間設置單向離合器，以使當繩CD向前方移動時旋轉被傳遞至阻力賦予部RA，但當繩CD向後方移動時旋轉不會被傳遞至阻力賦予部RA。 In addition, in the clamped state, the rotation of the output shaft 95 may be output to the resistance imparting part RA. That is, by the friction force acting between the knurling roller 240 and the endless belt 94, the endless belt 94 rotates in the direction opposite to the arrow D5 (counterclockwise) with respect to the output shaft 95. Thereby, the output shaft 95 also rotates (rotates) in the same direction as the endless belt 94 (counterclockwise). This rotation is output to the resistance imparting part RA. In this configuration, one of the output shafts 95 performs the same function as the shaft core 31 in the second embodiment (transmits rotation to the resistance imparting portion RA). At this time, a one-way clutch may be provided between the knurled roller 240 and the resistance imparting part RA, so that when the rope CD moves forward, the rotation is transmitted to the resistance imparting part RA, but when the rope CD moves backward, the rotation does not rotate. It will be transmitted to the resistance providing part RA.

另一方面，當對繩CD朝向與箭頭D4相反的方向施加張力時，透過產生與上述動作相反方向的動作，滾花輥240與支柱92在垂直方向上的距離變遠，從而對繩CD的夾持力變弱。 On the other hand, when tension is applied to the rope CD in the direction opposite to the arrow D4, the vertical distance between the knurling roller 240 and the support 92 becomes longer by generating a movement in the opposite direction to the above-mentioned movement, and the rope CD is The clamping force becomes weaker.

接著，如圖24(a)所示，軸芯31反抗重力g，而向從環形帶遠離的位置、亦即第二位置移動。將該狀態稱為自由移動狀態。在自由移動狀態下，繩CD以非彎曲狀態被釋放。然後，能夠允許繩CD的自由移動。 Then, as shown in FIG. 24(a), the shaft core 31 resists the gravity g and moves to a position away from the endless belt, that is, the second position. This state is called a free movement state. In the freely moving state, the cord CD is released in a non-bent state. Then, the free movement of the cord CD can be allowed.

另外，亦可取代支柱92，而使用軸芯和輥部。 In addition, instead of the pillar 92, a shaft core and a roller may be used.

如此，在第三實施方式中，透過移動軌跡(限制槽)超過滾花輥240的初始狀態下的夾持位置而延伸，從而即使在滾花輥240的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, in the third embodiment, the movement trajectory (restriction groove) extends beyond the nip position of the knurled roller 240 in the initial state, so that even when the diameter of the knurled roller 240 becomes smaller due to wear, The cord CD can also be clamped appropriately.

4.第四實施方式 4. Fourth Embodiment

接著，利用圖25對本發明第四實施方式之運動轉換部進行說明。第四實施方式是第二實施方式變形後的構成。因此，以下僅對來自第二實施方式的變更點進行說明。如圖23所示，第二實施方式中係構成為利用重力g使軸芯31及滾花輥240朝下方下降，可以說是利用重力g作為施力部件。相對於此，在第四實施方式中如圖25所示，軸芯31利用連結部件170與固定軸160連結。在此，連結部件170可以利用例如圖21的板片800。而且，連結部件170上安裝有彈簧150。藉此，透過以固定軸160為中心對連結部件170朝向箭頭g方向施力，從而將軸芯31和滾花輥240向箭頭g方向施力。 Next, the motion conversion unit of the fourth embodiment of the present invention will be described with reference to FIG. 25. The fourth embodiment is a modified configuration of the second embodiment. Therefore, only the changes from the second embodiment will be described below. As shown in FIG. 23, in the second embodiment, the shaft core 31 and the knurled roller 240 are lowered downward by gravity g, and it can be said that gravity g is used as a urging member. In contrast, in the fourth embodiment, as shown in FIG. 25, the shaft core 31 is connected to the fixed shaft 160 by the connecting member 170. Here, the connecting member 170 can use, for example, the plate 800 of FIG. 21. Furthermore, a spring 150 is attached to the connecting member 170. Thereby, by urging the connecting member 170 in the direction of the arrow g with the fixed shaft 160 as the center, the shaft core 31 and the knurling roller 240 are urged in the direction of the arrow g.

另外，在第四實施方式中也與第三實施方式同樣地，第一側壁孔119A相當於限制槽，且超過第一夾持部件(滾花輥240)的初始狀態下的夾持位置而延伸。另外，在圖25(b)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。另外，圖25(b)中的雙箭頭表示夾持體的移動軌跡。 In addition, in the fourth embodiment, similarly to the third embodiment, the first side wall hole 119A corresponds to the restriction groove, and extends beyond the clamping position of the first clamping member (knurled roller 240) in the initial state. . In addition, in FIG. 25(b), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn. In addition, the double arrow in FIG. 25(b) indicates the movement trajectory of the holder.

當從圖25(a)所示的自由移動狀態對繩CD朝向箭頭D6方向施加張力時，利用與繩CD之間產生的摩擦力，軸芯31和滾花輥240也朝向箭頭D6方向移動。此時，透過連結部件170以固定軸160為中心進行順時針轉動，軸芯31和滾花輥240朝向箭頭g方向移動。藉此，向圖25(b)所示的夾持狀態轉變。此時，滾花輥240的移動軌跡是沿著第一側壁孔119A的軌跡。另外，如圖25(b)所示，移動軌跡超過規定的夾持位置而延伸。 When tension is applied to the rope CD in the direction of the arrow D6 from the freely moving state shown in FIG. 25(a), the shaft core 31 and the knurling roller 240 also move in the direction of the arrow D6 by the friction generated with the rope CD. At this time, the connecting member 170 rotates clockwise with the fixed shaft 160 as the center, and the shaft core 31 and the knurled roller 240 move in the arrow g direction. Thereby, it transitions to the clamped state shown in FIG. 25(b). At this time, the movement trajectory of the knurling roller 240 is along the trajectory of the first side wall hole 119A. In addition, as shown in FIG. 25(b), the movement trajectory extends beyond the predetermined clamping position.

另外，當對繩CD朝向與箭頭D6相反的方向施加張力時，從圖25(b)所示的夾持狀態向圖25(a)所示的自由移動狀態轉變。 In addition, when tension is applied to the cord CD in the direction opposite to the arrow D6, it transitions from the gripping state shown in FIG. 25(b) to the free movement state shown in FIG. 25(a).

亦即，使用了第四實施方式之部件的裝置係構成為：滾花輥240以如下方式移動，亦即，滾花輥240位於第二位置時作用於滾花輥240和繩CD之間的摩擦力小於滾花輥240位於第一位置時作用於滾花輥240和繩CD之間的摩擦力。 That is, the device using the components of the fourth embodiment is configured such that the knurling roller 240 moves in such a way that when the knurling roller 240 is in the second position, it acts between the knurling roller 240 and the cord CD The frictional force is smaller than the frictional force acting between the knurled roller 240 and the cord CD when the knurled roller 240 is in the first position.

另外，與第三實施方式同樣地，在將軸芯31的旋轉輸出至伴隨著繩CD的移動而產生阻力的阻力賦予部RA之情形下，使用了第四實施方式的部件之裝置構成為：當滾花輥240位於第一位置時將由繩CD的移動引起之滾花輥240的旋轉輸出至阻力賦予部RA，當滾花輥240位於第二位置時不將由繩CD的移動引起之滾花輥240的旋轉輸出至阻力賦予部RA。 In addition, similarly to the third embodiment, in the case of outputting the rotation of the shaft core 31 to the resistance imparting portion RA that generates resistance along with the movement of the cord CD, a device using the components of the fourth embodiment is configured as follows: When the knurling roller 240 is at the first position, the rotation of the knurling roller 240 caused by the movement of the cord CD is output to the resistance imparting part RA, and when the knurling roller 240 is at the second position, the knurling caused by the movement of the cord CD is not knurled The rotation of the roller 240 is output to the resistance imparting part RA.

<第四實施方式之變形例> <Modifications of the fourth embodiment>

接著，利用圖26對第四實施方式之變形例進行說明。如圖26所示，由第一夾持部件(滾花輥240)和第二夾持部件(夾持平面132s)構成一對夾持部件。殼體10B將滾花輥240包含於內部。即，殼體10B將一對夾持部件的至少一方包含於內部。在此，圖中的虛線CB是顯示殼體10B的底面的線。進而，殼體10B具備第一側壁孔119A。 Next, a modification example of the fourth embodiment will be described with reference to FIG. 26. As shown in FIG. 26, the first clamping member (knurled roller 240) and the second clamping member (clamping plane 132s) constitute a pair of clamping members. The housing 10B contains the knurled roller 240 inside. That is, the housing 10B includes at least one of the pair of clamping members inside. Here, the broken line CB in the figure is a line showing the bottom surface of the housing 10B. Furthermore, the housing 10B has a first side wall hole 119A.

夾持平面132s在自由移動狀態下允許繩CD的移動，在夾持狀態下與滾花輥240一同夾持繩CD。另外，夾持平面132s是在滾花輥240的移動的前後被固定之平面。 The clamping plane 132s allows the movement of the rope CD in the freely moving state, and clamps the rope CD together with the knurled roller 240 in the clamping state. In addition, the nip plane 132s is a plane that is fixed before and after the movement of the knurling roller 240.

在第四實施方式之變形例中也與第四實施方式同樣地，第一側壁孔119A相當於限制槽，且超過第一夾持部件(滾花輥240)的初始狀態下的夾持位置而延伸。另外，圖26(b)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。另外，圖26(b)中的雙箭頭表示滾花輥240(軸芯31)的移動軌跡。 In the modification of the fourth embodiment, similarly to the fourth embodiment, the first side wall hole 119A corresponds to the restriction groove and exceeds the clamping position of the first clamping member (knurled roller 240) in the initial state. extend. In addition, in FIG. 26(b), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn. In addition, the double arrow in FIG. 26(b) indicates the movement locus of the knurling roller 240 (shaft core 31).

當從圖26(a)所示的自由移動狀態對繩CD朝向箭頭D7方向施加張力時，利用與繩CD之間產生的摩擦力，軸芯31和滾花輥240也朝箭頭D7方向移動。此時，連結部件170以固定軸160為中心進行順時針轉動，藉此軸芯31和滾花輥240向箭頭g方向移動。藉此，向圖26(b)所示的夾持狀態轉變。此時，滾花輥240的移動軌跡為沿著第一側壁孔119A的軌跡。另外，如圖26(b)所示，移動軌跡超過規定的夾持位置而延伸。 When tension is applied to the rope CD in the direction of the arrow D7 from the freely moving state shown in FIG. 26(a), the shaft core 31 and the knurled roller 240 also move in the direction of the arrow D7 by the frictional force generated with the rope CD. At this time, the connecting member 170 rotates clockwise around the fixed shaft 160, whereby the shaft core 31 and the knurled roller 240 move in the arrow g direction. Thereby, it transitions to the clamped state shown in FIG. 26(b). At this time, the movement trajectory of the knurling roller 240 is a trajectory along the first side wall hole 119A. In addition, as shown in FIG. 26(b), the movement trajectory extends beyond the predetermined clamping position.

另外，當對繩CD朝向與箭頭D7相反的方向施加張力時，從圖26(b)所示的夾持狀態向圖26(a)所示的自由移動狀態轉變。 In addition, when tension is applied to the cord CD in the direction opposite to the arrow D7, it transitions from the gripping state shown in FIG. 26(b) to the free movement state shown in FIG. 26(a).

亦即，使用了第四實施方式之變形例的部件之裝置係構成為：滾花輥240以如下方式移動，亦即，滾花輥240位於第二位置時作用於滾花輥240和繩CD之間的摩擦力小於滾花輥240位於第一位置時作用於滾花輥240和繩CD之間的摩擦力。 That is, the device system using the components of the modification of the fourth embodiment is configured such that the knurling roller 240 moves in such a way that when the knurling roller 240 is in the second position, it acts on the knurling roller 240 and the cord CD The frictional force therebetween is smaller than the frictional force acting between the knurled roller 240 and the cord CD when the knurled roller 240 is in the first position.

在此，夾持平面132s可以為上樑HB的底面132或與上樑HB不同的部件的底面。 Here, the clamping plane 132s may be the bottom surface 132 of the upper beam HB or the bottom surface of a component different from the upper beam HB.

接著，利用圖27，對於即使在第一夾持部件(滾花輥240)因磨損而直徑變小之情形下也能夠適當地夾持繩CD該一情況進一步詳細地說明。在此，圖27相當於圖26(b)所示的夾持狀態。 Next, using FIG. 27, the case where the cord CD can be clamped appropriately even when the diameter of the first clamping member (knurled roller 240) becomes smaller due to wear will be described in further detail. Here, FIG. 27 corresponds to the clamped state shown in FIG. 26(b).

如圖中的虛線所示，磨損前的滾花輥240在規定的夾持位置夾持繩CD。而且，磨損後的滾花輥240與磨損前相比直徑變小。因此，在磨損後的夾持位置，滾花輥240和繩CD之間出現距離，無法適當地夾持繩CD。但是，透過移動軌跡(相當於限制槽的第一側壁孔119A)超過滾花輥240的初始狀態(磨損前)的夾持位置而延伸，磨損後的滾花輥240變成滾花輥240移動至超過磨損前的夾持位置之位置並在該夾持位置夾持繩CD該一狀態。 As shown by the broken line in the figure, the knurled roller 240 before being worn clamps the cord CD at a predetermined clamping position. Furthermore, the diameter of the knurled roller 240 after wear becomes smaller than that before wear. Therefore, there is a distance between the knurled roller 240 and the rope CD at the worn clamping position, and the rope CD cannot be clamped properly. However, when the movement track (corresponding to the first side wall hole 119A of the restriction groove) extends beyond the nip position of the knurled roller 240 in the initial state (before abrasion), the worn knurled roller 240 becomes the knurled roller 240 and moves to Exceed the position of the clamping position before wear and clamp the rope CD at the clamping position.

5.第五實施方式 5. Fifth Embodiment

接著，利用圖28~圖34對第五實施方式之制動裝置5000進行說明。本實施方式之制動裝置5000如圖28等所示，形成為運動轉換部DT和阻力賦予部RA並列配置該一構成。以下，對本實施方式之概要進行說明。 Next, the brake device 5000 of the fifth embodiment will be described with reference to FIGS. 28 to 34. As shown in FIG. 28 and the like, the brake device 5000 of the present embodiment is configured such that the motion conversion portion DT and the resistance imparting portion RA are arranged side by side. Hereinafter, the outline of this embodiment will be described.

如圖28~圖30所示，運動轉換部DT由抓輥(catch roller)32A和抓輥32B構成，其中，抓輥32A由內筒42A和外筒240A構成，抓輥32B為所謂的固定滑輪、且由以能夠旋轉之方式安裝在軸芯31上的滾花輥240構成。另外，抓輥32A、32B均設置在殼體440A上。利用抓輥32A、32B的轉動轉矩夾持繩CD。另外，繩CD經由繩插通孔14A***通於運動轉換部DT。對於抓輥32A，之後更詳細地進行說明。 As shown in FIGS. 28-30, the motion conversion part DT is composed of a catch roller 32A and a catch roller 32B. The catch roller 32A is composed of an inner cylinder 42A and an outer cylinder 240A, and the catch roller 32B is a so-called fixed pulley. , And is composed of a knurled roller 240 mounted on the shaft core 31 in a rotatable manner. In addition, the grab rollers 32A and 32B are both provided on the housing 440A. The rope CD is clamped by the rotation torque of the grab rollers 32A and 32B. In addition, the rope CD is inserted into the motion conversion part DT via the rope insertion hole 14A. The grip roller 32A will be described in more detail later.

阻力賦予部RA是所謂的離心式調速器，且是如下的部件：亦即，平衡塊340A以圖29所示的阻尼軸為中心進行公轉，當由於離心力平衡塊340A向外徑側移動時，平衡塊340A與殼體10Aa接觸發生摩擦從而產生制動力該一部件。使平衡塊340A旋轉的旋轉傳遞機構(未圖示)與抓輥32B的軸芯31連接，當抓輥32B旋轉時，該旋轉所涉及的動力經由旋轉傳遞機構被傳遞至阻力賦予部 RA，藉此平衡塊340A以阻尼軸為中心進行公轉。平衡塊340A的個數沒有限制，例如可以為兩個、四個、八個、十六個。 The resistance imparting part RA is a so-called centrifugal governor, and is a member: that is, the balance weight 340A revolves around the damper shaft shown in FIG. 29, and when the balance weight 340A moves to the outer diameter side due to centrifugal force , The balance weight 340A is in contact with the housing 10Aa, and friction occurs to generate a braking force for the component. A rotation transmission mechanism (not shown) that rotates the counterweight 340A is connected to the shaft core 31 of the grab roller 32B. When the grab roller 32B rotates, the power involved in the rotation is transmitted to the resistance imparting section via the rotation transmission mechanism RA, whereby the balance weight 340A revolves around the damper shaft. The number of balance weights 340A is not limited, for example, it can be two, four, eight, or sixteen.

抓輥32A係構成為：內筒42A和外筒240A相互能夠相對地旋轉且在該相對旋轉時具有滑動阻力。如圖31所示，以內筒42A的外周被外筒240A包住之方式構成。對於該情況，之後進行詳細說明。內筒42A的側面上設置有旋轉軸31B和導向軸31C，殼體440A上設置有旋轉軸31B的軸承和引導導向軸31C的移動的導向槽31Ca。亦即，抓輥32A構成為能夠以旋轉軸31B為中心進行轉動。導向槽31Ca以其一側使抓輥32A和繩CD接近、另一側使抓輥32A和繩CD遠離之方式設置。換言之，導向槽31Ca以從一側朝向另一側而抓輥32A從繩CD遠離之方式形成。在此，在第五實施方式中，導向槽31Ca相當於限制槽，且超過夾持體(抓輥32A和抓輥32B)的初始狀態下的夾持位置而延伸。另外，圖30(a)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。 The grab roller 32A is configured such that the inner tube 42A and the outer tube 240A can rotate relative to each other and have sliding resistance during the relative rotation. As shown in FIG. 31, it is comprised so that the outer periphery of 42 A of inner cylinders may be enclosed by 240 A of outer cylinders. This situation will be described in detail later. A rotating shaft 31B and a guide shaft 31C are provided on the side surface of the inner cylinder 42A, and a bearing for the rotating shaft 31B and a guide groove 31Ca for guiding the movement of the guide shaft 31C are provided on the housing 440A. That is, the grip roller 32A is configured to be able to rotate around the rotation shaft 31B. The guide groove 31Ca is provided so that the grab roller 32A and the rope CD are approached on one side, and the grab roller 32A and the rope CD are moved away from the other side. In other words, the guide groove 31Ca is formed so that the grip roller 32A is away from the cord CD from one side to the other side. Here, in the fifth embodiment, the guide groove 31Ca corresponds to the restriction groove, and extends beyond the nip position of the nip body (the grab roller 32A and the grab roller 32B) in the initial state. In addition, in FIG. 30(a), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn.

依據導向槽31Ca的上述結構，當繩CD朝向圖30中以圖中箭頭表示的制動方向移動時，抓輥32A以旋轉軸31B為中心進行轉動，伴隨於此導向軸31C沿導向槽31Ca移動。在此，在導向槽31Ca中，由夾持導向斜面31a、釋放導向斜面31b、夾持側限制面31c以及釋放側限制面31d形成內周面。而且，在圖30(a)所示的導向槽31Ca的一側上導向軸31C所處的位置(第一位置)處，抓輥32A的轉動被限制。在該狀態下，繩CD被抓輥32A、32B夾持，當繩CD進一步朝向制動方向移動時，抓輥32A的外筒240A相對於內筒42A進行旋轉，抓輥32B以軸芯31為中心進行轉動。亦即，利用與抓輥32B連接的阻力賦予部RA賦予阻力，從而對繩CD的移動進行制動。 According to the above structure of the guide groove 31Ca, when the cord CD moves in the braking direction indicated by the arrow in FIG. 30, the grab roller 32A rotates around the rotating shaft 31B, and the guide shaft 31C moves along the guide groove 31Ca. Here, in the guide groove 31Ca, an inner peripheral surface is formed by the clamping guide slope 31a, the release guide slope 31b, the clamping side restriction surface 31c, and the release side restriction surface 31d. Furthermore, at the position (first position) where the guide shaft 31C is located on the side of the guide groove 31Ca shown in FIG. 30(a), the rotation of the grip roller 32A is restricted. In this state, the rope CD is clamped by the grab rollers 32A and 32B. When the rope CD moves further in the braking direction, the outer cylinder 240A of the grab roller 32A rotates relative to the inner cylinder 42A, and the grab roller 32B is centered on the shaft core 31 Perform rotation. That is, the resistance is provided by the resistance imparting part RA connected to the grip roller 32B, and the movement of the cord CD is braked.

另外，依據導向槽31Ca的上述結構，當繩CD朝向圖30中以圖中箭頭表示的釋放方向移動時，抓輥32A以旋轉軸31B為中心進行轉動，伴隨於此導向軸31C沿導向槽31Ca移動。此時，抓輥32A的移動(轉動)軌跡是沿著導向槽 31Ca的軌跡。另外，如圖30(b)所示，移動軌跡超過規定的夾持位置而延伸。另外，後述的第五實施方式之變形例一~三也相同，因此省略了圖示和說明。 In addition, according to the above-mentioned structure of the guide groove 31Ca, when the cord CD moves in the release direction indicated by the arrow in FIG. 30, the grab roller 32A rotates around the rotating shaft 31B, and the guide shaft 31C follows the guide groove 31Ca. mobile. At this time, the movement (rotation) trajectory of the grab roller 32A is along the guide groove The trajectory of 31Ca. In addition, as shown in FIG. 30(b), the movement trajectory extends beyond the predetermined clamping position. In addition, modification examples 1 to 3 of the fifth embodiment described later are also the same, and therefore illustrations and descriptions are omitted.

而且，在圖30(b)所示之導向槽31Ca的另一側上導向軸31C所處的位置(第二位置)處，抓輥32A的轉動被限制。在該狀態下，繩CD未被抓輥32A、32B夾持或僅被以相對較弱的力夾持，即使繩CD進一步向釋放方向移動，使抓輥32B轉動的轉矩也不足，從而抓輥32B不轉動。因此，未被賦予由阻力賦予部RA施加的阻力。 Furthermore, at the position (second position) where the guide shaft 31C is located on the other side of the guide groove 31Ca shown in FIG. 30(b), the rotation of the grip roller 32A is restricted. In this state, the rope CD is not clamped by the grasping rollers 32A, 32B or is only clamped with a relatively weak force. Even if the rope CD moves further in the release direction, the torque for rotating the grasping roller 32B is insufficient, thereby grasping The roller 32B does not rotate. Therefore, the resistance applied by the resistance imparting portion RA is not provided.

概括言之，在從圖30(a)的狀態向圖30(b)的狀態變化的過程中，雖然由阻力賦予部RA對繩CD賦予了阻力，但在圖30(b)的狀態下阻力賦予部RA不發揮作用。而且，在圖30(b)的狀態下外筒240A與滾花輥240之間的距離比圖30(a)的狀態下的大，因此對繩CD的夾持力變弱。藉此，由於成為對繩CD施加的制動力被解除的狀態，因此實現了繩CD的自由移動。進而，在從圖30(b)的狀態向圖30(a)的狀態變化的過程中，由阻力賦予部RA對繩CD賦予阻力，在圖30(a)的狀態下繩CD被夾持的同時阻力賦予部RA發揮作用。 In summary, in the process of changing from the state of FIG. 30(a) to the state of FIG. 30(b), although resistance is imparted to the rope CD by the resistance imparting portion RA, the resistance is in the state of FIG. 30(b) The endowment department RA does not play a role. Furthermore, in the state of FIG. 30(b), the distance between the outer cylinder 240A and the knurling roller 240 is larger than that in the state of FIG. 30(a), so the clamping force of the cord CD becomes weak. Thereby, since the braking force applied to the cord CD is released, the free movement of the cord CD is realized. Furthermore, in the process of changing from the state of FIG. 30(b) to the state of FIG. 30(a), the resistance imparting portion RA imparts resistance to the rope CD. In the state of FIG. 30(a), the rope CD is clamped. At the same time, the resistance imparting part RA functions.

另外，內筒42A與外筒240A相對旋轉時的滑動阻力只要是在導向軸31C轉動至第一位置時不能相對旋轉的程度之阻力即可。鑒於此，抓輥32A的內筒42A和外筒240A可以如下構成。 In addition, the sliding resistance when the inner tube 42A and the outer tube 240A rotate relative to each other may be a resistance that cannot rotate relatively when the guide shaft 31C rotates to the first position. In view of this, the inner tube 42A and the outer tube 240A of the grip roller 32A may be configured as follows.

在一例中，透過如圖32(a)所示之向外筒240A內壓入內筒42A之壓入工序，而實現圖32(b)所示的抓輥32A。在另一例中，如圖33所示，在內筒42A的表面設置有彈性部42Aa，藉此能夠得到期望的阻力。在再一例中，如圖34所示，在內筒42A上設置有對外筒240A賦予壓力的彈簧部件42Ab，藉此能夠得到期望的阻力。進而，為了使阻力穩定，亦可用粘性強的潤滑油潤滑。 In one example, through the pressing process of pressing the inner cylinder 42A into the outer cylinder 240A as shown in FIG. 32(a), the gripping roller 32A shown in FIG. 32(b) is realized. In another example, as shown in FIG. 33, an elastic portion 42Aa is provided on the surface of the inner tube 42A, whereby a desired resistance can be obtained. In another example, as shown in FIG. 34, a spring member 42Ab that applies pressure to the outer tube 240A is provided on the inner tube 42A, whereby a desired resistance can be obtained. Furthermore, in order to stabilize the resistance, lubrication with strong lubricating oil can also be used.

<第五實施方式之變形例一> <Modification 1 of the Fifth Embodiment>

進而，如圖35所示，本變形例之制動裝置5100，除了使繩CD向釋放方向移動時之外，為了使導向軸31C位於第一位置，亦可在殼體10Aa上所設置的固定部441A與導向軸31C之間配置作為在旋轉軸31B上捲繞有線圈部的施力部件之扭簧31Cb，並利用扭簧31Cb對導向軸31C施力。在此，在本變形例中，導向槽31Ca相當於限制槽，且超過夾持部件(抓輥32A)的初始狀態下的夾持位置而延伸。另外，圖35(a)中以虛線的圓表示了規定的夾持位置。 Furthermore, as shown in FIG. 35, the brake device 5100 of the present modification example may be provided with a fixing portion provided on the housing 10Aa in order to position the guide shaft 31C in the first position in addition to when the cord CD is moved in the release direction. Between the 441A and the guide shaft 31C, a torsion spring 31Cb as an urging member in which a coil portion is wound around the rotating shaft 31B is arranged, and the guide shaft 31C is urged by the torsion spring 31Cb. Here, in this modified example, the guide groove 31Ca corresponds to a restriction groove, and extends beyond the nipping position in the initial state of the nipping member (grab roller 32A). In addition, in FIG. 35(a), the predetermined clamping position is indicated by a dotted circle.

如此，在本變形例中，也透過限制槽超過抓輥32A的初始狀態下的夾持位置而延伸，從而即使在抓輥32A的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, in this modification, the restriction groove extends beyond the gripping position of the grip roller 32A in the initial state, so that even if the diameter of the grip roller 32A becomes smaller due to wear, it can be gripped appropriately. Rope CD.

<第五實施方式之變形例二> <Modification 2 of the Fifth Embodiment>

接著，利用圖36和圖37對第五實施方式之變形例二的制動裝置5200進行說明。本變形例之制動裝置5200如圖36和圖37所示，形成為運動轉換部DT和阻力賦予部RA在左右方向(與紙面垂直的方向)並列配置之構成。以下，對本變形例之概要進行說明。 Next, the brake device 5200 of the second modification of the fifth embodiment will be described with reference to FIGS. 36 and 37. As shown in Figs. 36 and 37, the brake device 5200 of the present modification example has a configuration in which the motion conversion portion DT and the resistance imparting portion RA are arranged side by side in the left-right direction (direction perpendicular to the paper surface). Hereinafter, the outline of this modified example will be described.

如圖36所示，運動轉換部DT由抓輥32A和抓輥32B構成，其中，抓輥32A由內筒42A和外筒240A構成，抓輥32B由以能夠旋轉之方式安裝在軸芯31上的滾花輥240構成。內筒42A和外筒240A是與圖28和圖30相同的構成，以互相之間能夠相對旋轉之方式構成。另外，在內筒42A的側面上設置有旋轉軸31B和導向軸31C。本變形例中，抓輥32A也以旋轉軸31B為中心呈能夠轉動地構成。另外，導向槽31Ca在殼體440B的側面上設置於抓輥32B能夠向夾持繩CD的狀態和釋放(解除夾持)的狀態變化之位置。在此，在本變形例中，由抓輥32A和抓輥32B構成夾持體。另外，在本變形例中，導向槽31Ca相當於限制槽，且超過夾持體(抓輥32A和抓輥32B)的初始狀態下的夾持位置而延伸。另外，圖36(a)中以虛線的圓表示了規定的夾持位置。 As shown in FIG. 36, the movement conversion portion DT is composed of a gripping roller 32A and a gripping roller 32B. The gripping roller 32A is composed of an inner tube 42A and an outer tube 240A, and the gripping roller 32B is rotatably mounted on the shaft core 31.的knurled roller 240 constituted. The inner tube 42A and the outer tube 240A have the same configuration as in FIGS. 28 and 30, and are configured to be rotatable relative to each other. In addition, a rotating shaft 31B and a guide shaft 31C are provided on the side surface of the inner cylinder 42A. In this modified example, the gripping roller 32A is also configured to be rotatable with the rotating shaft 31B as the center. In addition, the guide groove 31Ca is provided on the side surface of the housing 440B at a position where the grasping roller 32B can change to the state of clamping the cord CD and the state of releasing (unclamping). Here, in this modified example, the gripper roller 32A and the gripper roller 32B constitute a nip body. In addition, in this modification, the guide groove 31Ca corresponds to a restriction groove, and extends beyond the nip position of the nip body (the grab roller 32A and the grab roller 32B) in the initial state. In addition, in FIG. 36(a), the predetermined clamping position is indicated by a dotted circle.

而且，在本變形例中，外筒240A的側面上設置有小齒輪50B。小齒輪50B具有相對於紙面位於垂直方向上的旋轉軸。而且，以與設置在阻力賦予部RA的傳遞齒輪261B內側的齒嚙合之方式形成。另外，在與傳遞齒輪261B外側的齒嚙合的位置上設置有增速齒輪280B。增速齒輪280B以能夠旋轉之方式安裝在支撐軸263B上。而且，如圖36(b)所示，在與增速齒輪280B同一軸上設置有與增速齒輪280B一體旋轉之平衡塊支架320B。而且，利用平衡塊支架320B保持平衡塊340B。在此，在本實施方式中，利用平衡塊支架320B保持四個平衡塊340B。 Furthermore, in this modification, a pinion gear 50B is provided on the side surface of the outer cylinder 240A. The pinion gear 50B has a rotation axis in a vertical direction with respect to the paper surface. Furthermore, it is formed so as to mesh with the teeth provided inside the transmission gear 261B of the resistance imparting portion RA. In addition, a speed increasing gear 280B is provided at a position that meshes with the teeth on the outer side of the transmission gear 261B. The speed increasing gear 280B is rotatably mounted on the support shaft 263B. Furthermore, as shown in FIG. 36(b), a counterweight bracket 320B that rotates integrally with the speed-increasing gear 280B is provided on the same axis as the speed-increasing gear 280B. Also, the balance weight 340B is held by the balance weight support 320B. Here, in this embodiment, the four balance weights 340B are held by the balance weight bracket 320B.

由於平衡塊支架320B以與增速齒輪280B一體旋轉之方式設置，因此，伴隨著增速齒輪280B的自轉，平衡塊支架320B也進行自轉。藉此，被平衡塊支架320B保持的平衡塊340B進行公轉。 Since the weight support 320B is provided so as to rotate integrally with the speed-increasing gear 280B, the weight support 320B also rotates along with the rotation of the speed-increasing gear 280B. Thereby, the weight 340B held by the weight holder 320B revolves.

如圖37所示，在本變形例中，三根繩CD呈水平地被夾持。該等繩CD插通於構成運動轉換部DT的繩插通孔14A中。另外，小齒輪50B從運動轉換部DT的殼體440B向外部突出，與阻力賦予部RA的傳遞齒輪261B嚙合，其中，阻力賦予部RA與運動轉換部DT相鄰配置。 As shown in FIG. 37, in this modification, the three cords CD are clamped horizontally. The cords CD are inserted into the cord insertion holes 14A constituting the motion conversion portion DT. In addition, the pinion gear 50B protrudes to the outside from the housing 440B of the motion conversion part DT, and meshes with the transmission gear 261B of the resistance imparting part RA, which is arranged adjacent to the motion conversion part DT.

因此，當對繩CD朝向制動方向施加張力時，利用外筒240A與繩CD之間產生的摩擦力，抓輥32A以旋轉軸31B為中心朝順時針方向轉動。此時，伴隨著抓輥32A的轉動，設置在外筒240A上的小齒輪50B也進行自轉，同時進行順時針轉動。於是，與小齒輪50B嚙合的傳遞齒輪261B開始朝向逆時針方向進行自轉。藉此，與傳遞齒輪261B嚙合的增速齒輪280B開始朝向順時針方向進行自轉。此時，由於增速齒輪280B的直徑比傳遞齒輪261B的直徑小，因此，由繩CD的移動引起之小齒輪50B的旋轉被增速並被傳遞至增速齒輪280B。此時，內筒42A和外筒240A利用兩者的滑動阻力而進行一體旋轉。 Therefore, when tension is applied to the rope CD in the braking direction, the friction force generated between the outer cylinder 240A and the rope CD causes the grab roller 32A to rotate in the clockwise direction with the rotating shaft 31B as the center. At this time, along with the rotation of the grab roller 32A, the pinion gear 50B provided on the outer cylinder 240A also rotates clockwise. Then, the transmission gear 261B meshed with the pinion gear 50B starts to rotate in the counterclockwise direction. Thereby, the speed increasing gear 280B meshed with the transmission gear 261B starts to rotate in the clockwise direction. At this time, since the diameter of the speed increasing gear 280B is smaller than the diameter of the transmission gear 261B, the rotation of the pinion gear 50B caused by the movement of the cord CD is increased and transmitted to the speed increasing gear 280B. At this time, the inner tube 42A and the outer tube 240A rotate integrally by the sliding resistance of both.

接著，透過增速齒輪280B的自轉，平衡塊340B開始朝向順時針方向進行公轉。接著，透過平衡塊340B與阻力賦予部RA的殼體10Aa的內壁抵接， 能夠使針對繩CD的移動的制動力發揮作用。而且，在圖36(a)的狀態時，透過導向軸31C與導向槽31Ca抵接，內筒42A的轉動被阻止。接著，當進一步對繩CD朝向制動方向施加張力時，外筒240A相對於內筒42A開始進行相對旋轉。藉此，在夾持繩CD的同時能夠使來自阻力賦予部RA的制動力發揮作用。 Then, through the rotation of the speed increasing gear 280B, the weight 340B starts to revolve in the clockwise direction. Then, the counterweight 340B abuts against the inner wall of the housing 10Aa of the resistance imparting portion RA, The braking force for the movement of the cord CD can be exerted. Furthermore, in the state of FIG. 36(a), the guide shaft 31C abuts against the guide groove 31Ca, and the rotation of the inner cylinder 42A is prevented. Then, when further tension is applied to the rope CD in the braking direction, the outer tube 240A starts to rotate relative to the inner tube 42A. Thereby, the braking force from the resistance imparting portion RA can be exerted while clamping the cord CD.

另一方面，當對繩CD朝向釋放方向施加張力時，抓輥32A以旋轉軸31B為中心向逆時針方向轉動。此時，小齒輪50B、傳遞齒輪261B以及增速齒輪280B進行與對繩CD的制動施加張力時的旋轉相反的旋轉。而且，在圖36(b)的狀態時，透過導向軸31C與導向槽31Ca抵接，內筒42A的轉動被阻止。接著，外筒240A相對於內筒42A繼續進行相對旋轉。該狀態下，與圖36(a)相比，外筒240A與滾花輥240之間的距離變大，不能充分地夾持繩CD。而且，由於不能充分地夾持繩CD，因此外筒240A的旋轉也被抑制。藉此，由繩CD的移動引起的旋轉變得無法被傳遞至阻力賦予部RA。 On the other hand, when tension is applied to the cord CD in the release direction, the grasping roller 32A rotates counterclockwise with the rotating shaft 31B as the center. At this time, the pinion gear 50B, the transmission gear 261B, and the speed-increasing gear 280B rotate opposite to the rotation when tension is applied to the brake of the rope CD. In the state of FIG. 36(b), the guide shaft 31C abuts against the guide groove 31Ca, and the rotation of the inner cylinder 42A is prevented. Then, the outer cylinder 240A continues to rotate relative to the inner cylinder 42A. In this state, the distance between the outer cylinder 240A and the knurled roller 240 becomes larger than that in FIG. 36(a), and the cord CD cannot be clamped sufficiently. Furthermore, since the cord CD cannot be clamped sufficiently, the rotation of the outer cylinder 240A is also suppressed. Thereby, the rotation caused by the movement of the cord CD cannot be transmitted to the resistance imparting part RA.

如此，在本變形例中，也透過限制槽超過抓輥32A或抓輥32B的初始狀態下的夾持位置而延伸，從而即使在抓輥32A或抓輥32B的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, in this modification, the restricting groove extends beyond the gripping position of the grab roller 32A or the grab roller 32B in the initial state, even if the diameter of the grab roller 32A or the grab roller 32B becomes smaller due to wear. It is also possible to clamp the cord CD appropriately.

<第五實施方式之變形例三> <Modification 3 of the Fifth Embodiment>

接著，利用圖38~圖40對第五實施方式之變形例三的制動裝置5300進行說明。本變形例之制動裝置5300如圖36和圖37所示，形成為運動轉換部DT和阻力賦予部RA在左右方向(與紙面垂直的方向)上並列配置之構成。以下，對本變形例之概要進行說明。 Next, the brake device 5300 of the third modification of the fifth embodiment will be described with reference to FIGS. 38 to 40. As shown in FIGS. 36 and 37, the brake device 5300 of this modification is formed in a configuration in which the motion conversion portion DT and the resistance imparting portion RA are arranged side by side in the left-right direction (direction perpendicular to the paper surface). Hereinafter, the outline of this modified example will be described.

如圖38所示，運動轉換部DT由抓輥830和抓輥840構成，其中，抓輥830由內筒830A和外筒830B構成，抓輥840具備以能夠旋轉之方式安裝在軸芯41上的滾花輥43。與圖31同樣地，內筒830A和外筒830B構成為：內筒830A以能夠旋轉之方式安裝在旋轉軸831上，內筒830A和外筒830B互相之間能夠相對旋轉且 對於規定以下的轉矩利用滑動阻力進行一體旋轉。但是，與圖31不同的是，旋轉軸831設置在抓輥830的中心，且被殼體810A軸支撐。另外，在從旋轉軸831偏心的位置上，朝向軸向兩側突出有導向軸850。另外，在本變形例中，抓輥840如圖39所示，以能夠旋轉之方式保持在能夠沿上下方向平行移動的移動殼體820的支撐槽821(參照圖39)中。在此，在本實施方式中，由抓輥830和840構成一對夾持部件(夾持體)。 As shown in FIG. 38, the movement conversion portion DT is composed of a gripping roller 830 and a gripping roller 840. The gripping roller 830 is composed of an inner tube 830A and an outer tube 830B. The gripping roller 840 is rotatably mounted on the shaft core 41.的knurling roller 43. 31, the inner tube 830A and the outer tube 830B are configured such that the inner tube 830A is rotatably mounted on the rotating shaft 831, and the inner tube 830A and the outer tube 830B can rotate relative to each other and For torques below the specified limit, the sliding resistance is used to perform integral rotation. However, unlike FIG. 31, the rotating shaft 831 is provided at the center of the grip roller 830 and is axially supported by the housing 810A. In addition, at a position eccentric from the rotation shaft 831, a guide shaft 850 protrudes toward both sides in the axial direction. In addition, in this modification, as shown in FIG. 39, the gripping roller 840 is rotatably held in the support groove 821 (refer to FIG. 39) of the movable housing 820 that can move in parallel in the vertical direction. Here, in this embodiment, the grip rollers 830 and 840 constitute a pair of nipping members (clamping bodies).

另外，在本實施方式中，阻力賦予部RA也是具備離心式調速器並將旋轉軸831的旋轉傳遞至離心式調速器而使其制動之部件，與上述變形例二相同，抓輥830的外筒830B的旋轉經由小齒輪50B(參照圖37)被傳遞至阻力賦予部RA。關於阻力賦予部RA的構成，可以適當使用已述的實施方式中所載之構成。 In addition, in this embodiment, the resistance imparting section RA is also a member that includes a centrifugal governor and transmits the rotation of the rotating shaft 831 to the centrifugal governor to brake it. It is the same as the second modification described above, the grip roller 830 The rotation of the outer cylinder 830B is transmitted to the resistance imparting part RA via the pinion gear 50B (refer to FIG. 37). Regarding the structure of the resistance imparting portion RA, the structure described in the above-mentioned embodiment can be appropriately used.

移動殼體820具備形成在抓輥830、840兩端的一對平行板822，各平行板822上形成有支撐槽821(參照圖39)。另外，在平行板822上方的前後方向的中央處形成有朝向上方開口的導向槽823。進而，平行板822在導向槽823的前方的位置處具有能夠供導向軸850***的長孔824，長孔824以導向軸850能夠沿前後方向移動的朝向形成。在此，在本變形例中，導向槽823相當於限制槽，且超過夾持體(抓輥830、840)的初始狀態下的夾持位置而延伸。另外，圖38(b)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。 The moving housing 820 includes a pair of parallel plates 822 formed at both ends of the grab rollers 830 and 840, and a support groove 821 is formed in each parallel plate 822 (refer to FIG. 39). In addition, a guide groove 823 that opens upward is formed at the center in the front-rear direction above the parallel plate 822. Furthermore, the parallel plate 822 has a long hole 824 into which the guide shaft 850 can be inserted at a position in front of the guide groove 823, and the long hole 824 is formed in an orientation in which the guide shaft 850 can move in the front-rear direction. Here, in this modified example, the guide groove 823 corresponds to the restriction groove, and extends beyond the nipping position in the initial state of the nipping body (gripping rollers 830 and 840). In addition, in FIG. 38(b), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn.

在此，在本變形例中，在未對繩CD施加張力的狀態(正常狀態)下，如圖38(a)所示，繩CD構成為僅與位於上方的抓輥830接觸、與抓輥840不接觸。 Here, in this modified example, in a state where tension is not applied to the rope CD (normal state), as shown in FIG. 38(a), the rope CD is configured to contact only the upper grip roller 830 and contact the grip roller 840 does not touch.

利用如上的構成，從未對繩CD施加張力的狀態(正常狀態)使繩CD朝向後方(圖38的右方)移動時，抓輥830的外筒830B欲朝向圖38(a)中的逆時針方向(箭頭X方向)旋轉，但是由於一對夾持部件、亦即抓輥830、840未 夾持繩CD(也參照圖39(a)、圖40(a))，因此，繩CD的移動作為抓輥830(外筒830B)的旋轉未能充分傳遞，從而外筒830B的旋轉不會被傳遞至阻力賦予部RA並對繩CD賦予阻力。另外，此情況下，即使外筒830B旋轉，內筒830A所具備的導向軸850也與移動殼體820的長孔824抵接，由於移動殼體820在前後方向上被殼體810A限制，因此內筒830A變得無法向逆時針方向旋轉。 With the above configuration, when the rope CD is moved backward (right in FIG. 38) without applying tension to the rope CD (normal state), the outer tube 830B of the grab roller 830 is about to face the reverse direction in FIG. 38(a) It rotates in the clockwise direction (arrow X direction), but due to a pair of clamping parts, namely the grab rollers 830 and 840, the The grip cord CD (also refer to Figure 39(a) and Figure 40(a)), therefore, the movement of the cord CD is not sufficiently transmitted as the rotation of the grab roller 830 (outer cylinder 830B), so the rotation of the outer cylinder 830B will not It is transmitted to the resistance imparting part RA and imparts resistance to the rope CD. In addition, in this case, even if the outer cylinder 830B rotates, the guide shaft 850 provided in the inner cylinder 830A abuts against the long hole 824 of the movable housing 820, and the movable housing 820 is restricted by the housing 810A in the front-rear direction. The inner cylinder 830A becomes unable to rotate in the counterclockwise direction.

另一方面，當繩CD朝向前方(圖38的左方)移動時，如圖38(b)所示，抓輥830的外筒830B朝順時針方向(箭頭Y方向)旋轉。此時，由於外筒830B與內筒830A之間存在滑動阻力，因此外筒830B與內筒830A開始進行一體旋轉。於是，在內筒830A旋轉的同時，內筒830A所具備的導向軸850朝向順時針方向旋轉，並推壓移動殼體820的長孔824的上面，從而將移動殼體820推至上方(參照圖38(b)、圖39(b)、圖40(b))。其結果是，被保持在移動殼體820上的抓輥840朝向上方、亦即靠近繩CD的方向移動，並與抓輥830協同動作而夾持繩CD。 On the other hand, when the cord CD moves forward (leftward in FIG. 38), as shown in FIG. 38(b), the outer tube 830B of the grip roller 830 rotates in the clockwise direction (arrow Y direction). At this time, since there is sliding resistance between the outer cylinder 830B and the inner cylinder 830A, the outer cylinder 830B and the inner cylinder 830A start to rotate integrally. Then, while the inner cylinder 830A rotates, the guide shaft 850 provided in the inner cylinder 830A rotates in the clockwise direction and pushes the upper surface of the elongated hole 824 of the movable housing 820, thereby pushing the movable housing 820 upward (refer to Figure 38(b), Figure 39(b), Figure 40(b)). As a result, the gripping roller 840 held on the moving housing 820 moves upward, that is, close to the cord CD, and cooperates with the gripping roller 830 to clamp the cord CD.

當在此狀態下繩CD進一步朝向前方(圖38的左方)移動時，繩CD的移動作為外筒830B的旋轉而傳遞。但是，在抓輥840與繩CD抵接後，由於移動殼體820不能再朝更上方移動，因此內筒830A也變成無法再旋轉的狀態，因而相對於內筒830A只有外筒830B在旋轉。 When the cord CD moves further forward (leftward in FIG. 38) in this state, the movement of the cord CD is transmitted as the rotation of the outer cylinder 830B. However, after the gripping roller 840 abuts the cord CD, since the movable housing 820 cannot move further upward, the inner cylinder 830A also becomes unable to rotate, and therefore only the outer cylinder 830B rotates relative to the inner cylinder 830A.

以上的結果是，當在圖38(b)的抓輥830和抓輥840夾持著繩CD的狀態下使繩CD朝向前方(圖38的左方)移動時，繩CD的移動作為外筒830B的旋轉被充分傳遞，阻力賦予部RA對外筒830B的旋轉賦予制動力，從而繩CD被制動。 The result of the above is that when the rope CD is moved forward (the left side of Fig. 38) with the grip roller 830 and the grip roller 840 in Fig. 38(b) sandwiching the rope CD, the movement of the rope CD acts as an outer cylinder The rotation of 830B is sufficiently transmitted, the resistance imparting portion RA imparts a braking force to the rotation of the outer cylinder 830B, and the cord CD is braked.

如此，在本變形例中，也透過限制槽超過抓輥830或抓輥840的初始狀態下的夾持位置而延伸，從而即使在抓輥830或抓輥840的直徑因磨損而變小之情形下，也能夠適當地夾持繩CD。 In this way, in this modification, the restricting groove extends beyond the gripping position of the gripping roller 830 or the gripping roller 840 in the initial state, even if the diameter of the gripping roller 830 or the gripping roller 840 becomes smaller due to wear. It is also possible to clamp the cord CD appropriately.

6.第六實施方式 6. Sixth Embodiment

接下來，利用圖41~圖43對本發明第六實施方式之制動裝置6000進行說明。本實施方式之制動裝置6000與第二實施方式所載之制動裝置1000類似。但是，本實施方式之制動裝置6000主要的不同點在於：一對夾持部件的各軸芯的軸向兩端側被由一對連接板721、722構成之連杆機構720所保持這一點。另外，在以下的說明中，對於與第一實施方式為相同構成的部件賦予相同的符號，並且主要對構成不同的部分進行說明。 Next, the braking device 6000 according to the sixth embodiment of the present invention will be described with reference to FIGS. 41 to 43. The braking device 6000 in this embodiment is similar to the braking device 1000 in the second embodiment. However, the main difference of the brake device 6000 of this embodiment is that the axial ends of the shaft cores of the pair of clamping members are held by the link mechanism 720 composed of a pair of connecting plates 721 and 722. In addition, in the following description, the same reference numerals are given to members having the same configuration as those of the first embodiment, and parts with different configurations are mainly described.

在此，第六實施方式之制動裝置6000與第一實施方式~第五實施方式不同，是不具有限制槽之實施方式。另外，圖43(a)中以虛線的圓表示了規定的夾持位置，以下的說明是對夾持體磨損後的動作進行說明。 Here, the brake device 6000 of the sixth embodiment is different from the first embodiment to the fifth embodiment in that it is an embodiment that does not have a restricting groove. In addition, in FIG. 43(a), the predetermined clamping position is indicated by a dotted circle, and the following description is to describe the operation after the clamping body is worn.

如圖41所示，本實施方式之一對夾持部件由具備滾花輥240的張力傳遞輥30和具備輥部42的空轉輥40構成。在上下方向延伸的張力傳遞輥30的軸芯31，其軸向兩端側被一對連接板721的一端側軸支撐，在上下方向延伸的空轉輥40的軸芯41也同樣地，其軸向兩端側被一對連接板722的一端側軸支撐。另外，張力傳遞輥30的軸芯31與上述第二實施方式相同，在與張力傳遞輥30相反側的端部上安裝有小齒輪50。 As shown in FIG. 41, one pair of nip members in the present embodiment is composed of a tension transmission roller 30 provided with a knurled roller 240 and an idle roller 40 provided with a roller portion 42. The shaft core 31 of the tension transmission roller 30 extending in the vertical direction has its axial ends supported by one end of a pair of connecting plates 721. The shaft core 41 of the idler roller 40 extending in the vertical direction is similarly supported. It is axially supported by one end of a pair of connecting plates 722 toward both ends. In addition, the shaft core 31 of the tension transmission roller 30 is the same as the second embodiment described above, and a pinion gear 50 is attached to the end on the opposite side to the tension transmission roller 30.

連接板721和連接板722經由***形成於板中央部的孔中的軸723以能夠相對旋轉之方式連接，形成連杆機構720。另外，在連接板721、722的另一端上設置有在上下方向延伸且將連接板721、722連結之連結銷724、725(參照圖42)。 The connecting plate 721 and the connecting plate 722 are connected in a relatively rotatable manner via a shaft 723 inserted into a hole formed in the center of the plate, forming a link mechanism 720. In addition, the other ends of the connecting plates 721 and 722 are provided with connecting pins 724 and 725 (refer to FIG. 42) that extend in the vertical direction and connect the connecting plates 721 and 722.

而且，連結銷724和連結銷725如圖43所示，利用作為軸723上捲繞有線圈部的施力部件之扭簧726而被向相互靠近的方向推壓。因此，連接板721和連接板722以下述方式被施力：亦即，以軸723作為中心朝向使各自所保持的張力傳遞輥30和空轉輥40相互靠近之方向旋轉該一方式，作為結果，繩CD被該等輥30、40夾持。另外，圖41中雖然未圖示，但是軸723被殼體10A軸支撐。 Furthermore, as shown in FIG. 43, the connecting pin 724 and the connecting pin 725 are pressed in the direction of approaching each other by a torsion spring 726 as an urging member in which the coil portion is wound on the shaft 723. Therefore, the connecting plate 721 and the connecting plate 722 are urged in such a manner that the tension transmission roller 30 and the idler roller 40 held by each are rotated with the shaft 723 as the center in a direction in which the tension transmission roller 30 and the idler roller 40 respectively held close to each other, and as a result, The rope CD is clamped by these rollers 30,40. In addition, although not shown in FIG. 41, the shaft 723 is axially supported by the housing 10A.

利用如上的構成，在如圖43(a)所示那樣未對繩CD施加張力的狀態(正常狀態)下，張力傳遞輥30和空轉輥40經由連杆機構720被扭簧726施力，藉此夾持繩CD。當在此狀態下繩CD向前方(圖43的左方)移動時，繩CD的移動傳遞至張力傳遞輥30，張力傳遞輥30的旋轉被依次傳遞至帶內齒的齒輪架260、行星齒輪280、帶恆星齒輪的平衡塊支架320，從而使平衡塊340(參照圖2)旋轉，並利用平衡塊340的旋轉阻力對繩CD施加制動力。亦即，在本實施方式中，伴隨著保持部件、亦即連杆機構720(連接板721和連接板722)的移動，夾持部件也夾持繩CD。此時，輥部42和滾花輥240的移動軌跡如圖43(a)中的雙箭頭所示。另外，如圖43(a)所示，移動軌跡超過規定的夾持位置而延伸。 With the above configuration, in a state (normal state) where no tension is applied to the cord CD as shown in Figure 43(a), the tension transmission roller 30 and the idler roller 40 are urged by the torsion spring 726 via the link mechanism 720, whereby This clamping rope CD. When the rope CD moves forward (the left side of FIG. 43) in this state, the movement of the rope CD is transmitted to the tension transmission roller 30, and the rotation of the tension transmission roller 30 is sequentially transmitted to the gear carrier 260 with internal teeth, the planetary gear 280. A balance weight support 320 with a sun gear, so that the balance weight 340 (refer to FIG. 2) is rotated, and the rotation resistance of the balance weight 340 is used to apply a braking force to the rope CD. That is, in the present embodiment, the clamping member also clamps the cord CD along with the movement of the holding member, that is, the link mechanism 720 (the connecting plate 721 and the connecting plate 722). At this time, the movement trajectory of the roller portion 42 and the knurled roller 240 is as shown by the double arrow in Fig. 43(a). In addition, as shown in FIG. 43(a), the movement trajectory extends beyond the predetermined clamping position.

另一方面，當繩CD向後方(圖43的右方)移動時，如圖43(b)所示，被連接板721保持的張力傳遞輥30和被連接板722保持的空轉輥40伴隨著繩CD的移動，對抗經由連杆機構720的扭簧726的作用力，以軸723為中心朝向張力傳遞輥30與空轉輥40之間的距離變大的方向旋轉。藉此，夾持體對繩CD的夾持變弱，經由張力傳遞輥30的阻力賦予部RA對繩CD施加的阻力減少。 On the other hand, when the cord CD moves backward (right in FIG. 43), as shown in FIG. 43(b), the tension transmission roller 30 held by the connecting plate 721 and the idle roller 40 held by the connecting plate 722 are accompanied by The movement of the cord CD opposes the urging force of the torsion spring 726 via the link mechanism 720 and rotates in a direction in which the distance between the tension transmission roller 30 and the idle roller 40 increases with the shaft 723 as the center. Thereby, the grip of the cord CD by the gripping body becomes weak, and the resistance applied to the cord CD via the resistance imparting portion RA of the tension transmission roller 30 is reduced.

另外，在上述實施方式中，連杆機構720構成為將一對連接板721、722配置在軸向兩端側，但是亦可構成為將一對連接板721、722僅配置在軸向一端側。 In addition, in the above-mentioned embodiment, the link mechanism 720 is configured such that the pair of connecting plates 721 and 722 are arranged on both ends in the axial direction. However, it may be configured such that the pair of connecting plates 721 and 722 are arranged only on one end of the axial direction. .

以上對各種實施方式進行了說明，但本發明並不限定於此，本發明之遮蔽裝置100A亦可是與上述實施方式之遮蔽裝置100A不同的構成。例如，本發明之日射遮蔽裝置亦可是捲繞有簾布的捲簾、或多個百葉片進行昇降的百葉窗。另外，如圖44所示，亦可使用螺絲111等將制動裝置1000固定在窗框110上。另外，亦可在把手109的內部設置制動裝置1000。進而，亦可在昇降繩102的通過路徑上的任意位置設置制動裝置1000。 Various embodiments have been described above, but the present invention is not limited to this, and the shielding device 100A of the present invention may have a different structure from the shielding device 100A of the above-mentioned embodiment. For example, the solar shading device of the present invention may also be a roller blind wound with a curtain, or a shutter in which a plurality of louvers are raised and lowered. In addition, as shown in FIG. 44, the brake device 1000 may be fixed to the window frame 110 using screws 111 or the like. In addition, the brake device 1000 may be provided inside the handle 109. Furthermore, the braking device 1000 may be provided at any position on the passage path of the lifting rope 102.
