Description
本發明大體而言係針對傾斜座椅及用於固定傾斜位置之鎖定設備，且更特定言之係針對一般用於輕便座椅及相關傢具上的懸臂支架型傾斜機構之鎖定設備。The present invention is generally directed to tilting seats and locking devices for securing tilted positions, and more particularly to locking devices commonly used in cantilever-bracket-type tilting mechanisms on lightweight seats and related furniture.
一般需要座椅能夠由人隨意使之向後傾斜。可藉由使用包括彈簧、機械軸及汽缸之各種類型的機構來達成傾斜特徵；然而，龐大及複雜程度較低之傾斜機構為懸臂支架。懸臂支架由大體而言剛性之材料製成，該材料在向其施加負載時撓曲。懸臂支架於一末端附著至座椅之上部部分且在另一末端附著至座椅之下部部分，且具有足夠剛性以在座椅為空或人豎直地坐於座椅中時將座椅之上部部分保持於豎直位置。然而，當人向後靠在座椅之上部部分上時，懸臂支架撓曲，藉此允許座椅之上部部分相對於座椅之下部部分傾斜。懸臂支架可用於任何類型之座椅中，但最常用於輕便的戶外餐椅。It is generally desirable that the seat can be tilted backwards by a person. Tilting features can be achieved by using various types of mechanisms including springs, mechanical shafts, and cylinders; however, the bulky and less complex tilting mechanism is a cantilevered bracket. The cantilever bracket is made of a generally rigid material that flexes when a load is applied thereto. The cantilever bracket is attached to the upper portion of the seat at one end and to the lower portion of the seat at the other end, and has sufficient rigidity to seat the seat when the seat is empty or when the person sits vertically in the seat The upper portion is held in an upright position. However, when the person leans back against the upper portion of the seat, the cantilever bracket flexes, thereby allowing the upper portion of the seat to be inclined relative to the lower portion of the seat. The cantilever bracket can be used in any type of seat, but is most commonly used for light outdoor dining chairs.
雖然需要座椅能夠傾斜，但有時需要禁用傾斜機構。舉例而言，當人正於桌邊進餐時，傾斜之座椅可為不正式、使人分心及/或因其他原因而不合需要的。因此，在座椅上具有傾斜鎖定裝置以使得可由人隨意啟動及關閉傾斜特徵為有利的。因此揭示了用於鎖定懸臂支架傾斜機構之傾斜機構，防止具有懸臂支架型傾斜機構之座椅向後傾斜之可靠設備。Although the seat is required to be tilted, it is sometimes necessary to disable the tilt mechanism. For example, when a person is eating at a table, the tilted seat can be unform, distracting, and/or undesirable for other reasons. Therefore, it is advantageous to have a tilt locking device on the seat so that the tilting feature can be arbitrarily activated and deactivated by a person. Therefore, a tilting mechanism for locking the tilting mechanism of the cantilever bracket is disclosed, and a reliable device for tilting the seat having the cantilever bracket type tilting mechanism is prevented.
在一態樣中，本揭示案包括一種設備，其包含具有一遠端及一近端之懸臂支架、耦接至遠端之框架部分、耦接至近端之基座部分，及耦接至框架部分、基座部分或懸臂支架的鎖定設備，其中該鎖定設備具有一鎖定位置及一未鎖定位置，且其中當鎖定設備處於鎖定位置時，鎖定設備防止框架部分相對於基座部分傾斜。在鎖定位置，鎖定設備可支撐懸臂支架之遠端，限制懸臂支架之向下撓曲。在一實施例中，鎖定設備包括一塊體，且鎖定設備在其鎖定位置中接觸懸臂支架與基座部分。In one aspect, the present disclosure includes an apparatus including a cantilever bracket having a distal end and a proximal end, a frame portion coupled to the distal end, a base portion coupled to the proximal end, and coupled to A locking portion of the frame portion, the base portion or the cantilever bracket, wherein the locking device has a locked position and an unlocked position, and wherein the locking device prevents the frame portion from tilting relative to the base portion when the locking device is in the locked position. In the locked position, the locking device can support the distal end of the cantilever bracket, limiting the downward deflection of the cantilever bracket. In an embodiment, the locking device includes a body and the locking device contacts the cantilever bracket and the base portion in its locked position.
在另一態樣中，本揭示案包括一種傢具，其包含：一基座部分；一框架部分，其耦接至該基座部分以使得該框架部分相對於基座部分傾斜；及一具有一鎖定位置及一未鎖定位置之鎖定設備，其中當鎖定設備處於鎖定位置時，鎖定設備卡在框架部分與基座部分之間，藉此防止框架部分相對於基座部分傾斜，且其中當鎖定設備處於未鎖定位置時，框架部分相對於基座部分傾斜。In another aspect, the present disclosure includes a piece of furniture comprising: a base portion; a frame portion coupled to the base portion such that the frame portion is inclined relative to the base portion; and having a a locking device in a locked position and an unlocked position, wherein when the locking device is in the locked position, the locking device is caught between the frame portion and the base portion, thereby preventing the frame portion from tilting relative to the base portion, and wherein when the locking device is When in the unlocked position, the frame portion is inclined relative to the base portion.
在第三態樣中，本揭示案包括一種座椅，其包含：一基座；一傾斜體，其耦接至該基座以使得該傾斜體相對於基座旋轉；一具有一耦接至傾斜體之近端及一遠端之懸臂支架；一耦接至該遠端之框架，該框架支撐一座位；及一具有一鎖定位置及一未鎖定位置且耦接至傾斜體、懸臂支架或框架的鎖定設備。In a third aspect, the present disclosure includes a seat comprising: a base; an inclined body coupled to the base to rotate the tilting body relative to the base; one having a coupling to a proximal end of the inclined body and a distal cantilever bracket; a frame coupled to the distal end, the frame supports a seat; and a locking position and an unlocked position coupled to the inclined body, the cantilever bracket or The locking device of the frame.
如圖1至圖6中可見，併入有輕便控制傾斜鎖定裝置之座椅100一般包含四個組件：框架部分110、基座部分120、一或多個懸臂支架130，及鎖定設備140。在圖1中，框架部分110包含座位112及框架114。座位112一般(但未必)經加以襯墊來緩衝且支撐坐於座椅100中之人。框架114提供對座位112之結構支撐且將座位112連接至一或多個懸臂支架130。一或多個懸臂支架130允許框架部分110相對於基座部分120向後傾斜。As seen in Figures 1-6, a seat 100 incorporating a lightweight controlled tilt lock generally comprises four components: a frame portion 110, a base portion 120, one or more cantilever brackets 130, and a locking device 140. In FIG. 1, frame portion 110 includes a seat 112 and a frame 114. Seat 112 is generally (but not necessarily) cushioned to support and support a person seated in seat 100. The frame 114 provides structural support for the seat 112 and connects the seat 112 to one or more cantilever brackets 130. One or more cantilever brackets 130 allow the frame portion 110 to be tilted rearward relative to the base portion 120.
在圖1中，基座部分120包含基座122及傾斜體124。基座122將座椅100支撐於地面上且一般在其底部寬於座椅100之最寬部分。該組態有助於防止座椅100被坐在座椅100中之人的動作翻倒，藉此改良座椅100之穩定性。在圖1中，傾斜體124包含機械軸125、傾斜體本體126及頭部127。機械軸125一般為自傾斜體本體126向下延伸之圓柱桿且在圖1及圖2中以虛線展示。在圖1中，機械軸125安裝至基座122頂部之孔中且可在基座122內旋轉以使得傾斜體124、懸臂支架130及框架部分110可相對於基座122旋轉360度。在圖1中，傾斜體本體126在水平及豎直方向上均延伸遠離機械軸125。因此，在圖1中，傾斜體本體126升高且延伸遠離(向前)基座122而提供傾斜或斜面支撐。傾斜體本體126之水平及豎直態樣允許將框架114定位於傾斜體本體126上方，其中具有空間來將塊體148安裝於框架114與傾斜體本體126之間，該塊體148為在下文中更為詳細描述之特徵。圖1中之頭部127將傾斜體124連接至至少一懸臂支架130。倘若座椅100配備有複數個懸臂支架130，則頭部127可在水平面中向外(向側面)延伸遠離傾斜體本體126以在複數個懸臂支架130之間形成足夠間隔(提供空間用於鎖定設備l40)，如圖3所示。傾斜體124之兩個實例為於1999年2月11日申請之頒予Sulzer的題為"Casual Chair Control"之美國專利第D422,814號及於2004年7月1日申請之頒予Sulzer的題為"Casual Tilter"之美國專利第D520,780號，該等專利均如同以其全文複製一般而以引用方式併入。In FIG. 1, the base portion 120 includes a base 122 and an inclined body 124. The base 122 supports the seat 100 on the ground and is generally wider at its bottom than the widest portion of the seat 100. This configuration helps to prevent the seat 100 from being tipped over by the person sitting in the seat 100, thereby improving the stability of the seat 100. In FIG. 1, the inclined body 124 includes a mechanical shaft 125, an inclined body 126, and a head 127. The mechanical shaft 125 is generally a cylindrical rod that extends downwardly from the inclined body 126 and is shown in phantom in Figures 1 and 2. In FIG. 1, mechanical shaft 125 is mounted into a bore in the top of base 122 and is rotatable within base 122 such that tilt body 124, cantilever bracket 130, and frame portion 110 can be rotated 360 degrees relative to base 122. In FIG. 1, the inclined body 126 extends away from the mechanical shaft 125 in both the horizontal and vertical directions. Thus, in Figure 1, the slant body 126 is raised and extends away from the (forward) pedestal 122 to provide a sloped or beveled support. The horizontal and vertical aspects of the inclined body 126 allow the frame 114 to be positioned over the inclined body 126 with space to mount the block 148 between the frame 114 and the inclined body 126, which is hereinafter A more detailed description of the features. The head 127 of FIG. 1 connects the inclined body 124 to at least one cantilever bracket 130. If the seat 100 is equipped with a plurality of cantilever brackets 130, the head 127 can extend outwardly (toward the side) away from the inclined body 126 in a horizontal plane to provide sufficient spacing between the plurality of cantilever brackets 130 (providing space for locking) Device l40), as shown in FIG. Two examples of the slanting body 124 are U.S. Patent No. D422,814, entitled "Casual Chair Control", issued to Sulzer on February 11, 1999, and to Sulzer, filed on July 1, 2004. U.S. Patent No. D 520,780, the entire disclosure of which is incorporated herein by reference in its entirety in its entirety in its entirety in its entirety in its entirety in its entirety in its entirety.
一或多個懸臂支架130為允許框架部分110相對於基座部分120傾斜之組件。一般熟習此項技術者應瞭解框架部分110可以相對於水平線之任何角度而傾斜。在特定實施例中，傾斜角度為5度、10度、15度、20度、25度、30度、35度、40度、45度、50度、55度、60度或任何其他角度。雖然可在座椅100中使用任何數目之懸臂支架130，但在圖1、圖3及圖5中座椅100經組態有兩個懸臂支架130。在圖1中，懸臂支架130於其近端132栓接、焊接或以其它方式連接至傾斜體124且於其遠端134栓接、焊接或以其它方式連接至框架114。此等連接為大體而言剛性之連接，從而(例如)遠端134與框架114如同一體般豎直移動。在圖1中，懸臂支架130為大體矩形之平坦材料片，其可操作以在重量下撓曲從而允許框架部分110相對於基座部分120傾斜。藉由將框架114附著至懸臂支架130之遠端134(遠離懸臂支架130至傾斜體124之頭部127的附著)，座椅經設計以在向框架部分110施加足夠重量時(諸如藉由就座者向後靠在座椅中)向後傾斜(向後，朝向斜倚位置)。參看圖1之懸臂支架130，近端一般指面對座椅之正面方向之末端132，且遠端一般指面對座椅之背面方向的末端134(但一般熟習此項技術者應瞭解此等術語之特定取向可為任意的且該等術語可用以描述組件之任兩個相反末端)。雖然多種材料適於製作懸臂支架，但對於圖1之較佳材料為金屬，尤其為鋁、鐵或鋼。一般熟習此項技術者能夠基於多種因素而選擇對於達成所要傾斜量為必要的材料之特定等級及材料厚度，該等因素包括(但不限於)坐於座椅100中之人的重量、框架部分110之重量、所要傾斜量、懸臂支架130之長度，及座椅之設計。又，雖然座椅100之正面在本文中一般稱作近端且座椅100之背面一般稱作遠端，但一般熟習此項技術者應瞭解該等術語近及遠的特定取向為任意的且可用以描述座椅100之組件之任兩個相反末端。One or more cantilever brackets 130 are components that allow the frame portion 110 to be tilted relative to the base portion 120. Those of ordinary skill in the art will appreciate that the frame portion 110 can be tilted at any angle relative to the horizontal. In a particular embodiment, the angle of inclination is 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, or any other angle. While any number of cantilever brackets 130 can be used in the seat 100, the seat 100 is configured with two cantilever brackets 130 in FIGS. 1, 3, and 5. In FIG. 1, the cantilever bracket 130 is bolted, welded or otherwise coupled to the ramp 124 at its proximal end 132 and bolted, welded or otherwise attached to the frame 114 at its distal end 134. These connections are generally rigid connections such that, for example, the distal end 134 moves vertically with the frame 114 as one. In FIG. 1, cantilever bracket 130 is a generally rectangular piece of flat material that is operable to flex under weight to allow frame portion 110 to be tilted relative to base portion 120. By attaching the frame 114 to the distal end 134 of the cantilever bracket 130 (away from the attachment of the cantilever bracket 130 to the head 127 of the inclined body 124), the seat is designed to apply sufficient weight to the frame portion 110 (such as by The seater leans back in the seat) leaning backwards (backward, towards the reclined position). Referring to the cantilever bracket 130 of Figure 1, the proximal end generally refers to the end 132 facing the front of the seat, and the distal end generally refers to the end 134 facing the rear of the seat (although those skilled in the art should be aware of this The specific orientation of the terms can be any and the terms can be used to describe any two opposite ends of the component. While a variety of materials are suitable for making cantilevered supports, the preferred material for Figure 1 is metal, especially aluminum, iron or steel. Those skilled in the art will be able to select a particular grade and material thickness of the material necessary to achieve the desired amount of tilt based on a variety of factors including, but not limited to, the weight of the person sitting in the seat 100, the frame portion. The weight of 110, the amount of tilt required, the length of the cantilever bracket 130, and the design of the seat. Also, while the front side of the seat 100 is generally referred to herein as the proximal end and the back side of the seat 100 is generally referred to as the distal end, those of ordinary skill in the art will appreciate that the specific orientations of the terms are near and far arbitrary. It can be used to describe any two opposite ends of the components of the seat 100.
圖1之鎖定設備140包含一或多個托架150、一本體142、一臂144、一把手146及一塊體148。圖1之托架150夾緊傾斜體124或以其它方式緊固至傾斜體124上，且滑動地嚙合至鎖定設備之本體142以使得本體142可相對於傾斜體124向前(在近端方向上)及向後(在遠端方向上)滑動。圖1之托架150一般將本體142緊固於適當位置，同時視情況亦提供對於本體142之移動的足夠摩擦阻力來防止鎖定設備140無意中滑出其鎖定位置。圖1之塊體148連接至本體142之遠端且一般在鎖定設備140經定位於鎖定位置時防止框架部分110相對於基座部分120傾斜(因為塊體148支撐懸臂支架130之遠端134，限制懸臂支架向下之撓曲)。在圖1中，塊體148為支撐段，其近似為傾斜體本體126與未撓曲懸臂支架130之間的間隙之高度。因此，當圖1之鎖定設備140處於其鎖定位置(塊體148處於近端位置，楔入於懸臂支架130與傾斜體本體126之間)時，塊體148一般近似與框架114及機械軸125成一直線且充分地支撐懸臂支架130之遠端134，從而限制會允許框架部分110相對於座椅之基座部分120之向後傾斜的向下撓曲。在圖1中，臂144連接至本體142之近端且自座位112下延伸出。較佳地，臂144自座位112之正面延伸出，但一般熟習此項技術者應瞭解座椅100可經組態以使得臂144延伸出座位112之諸側中之一者或座位112之背面。不考慮圖1之臂144之位置，其視情況可安裝有把手146以促進鎖定設備140在鎖定位置與未鎖定位置之間的簡單使用者致動。雖然圖1及圖2未展示，但塊體148亦可在其頂部及/或底部表面上經組態有至少一襯墊149。襯墊149通常由比用於傾斜體124及/或框架114中之材料柔軟的材料製成，且因此防止塊體148擦傷或弄凹傾斜體124及/或框架114。視情況，襯墊亦可由具有較高摩擦係數之材料製成以幫助將塊體緊固於其鎖定位置。在一特定實施例中，襯墊149為諸如聚丙烯、聚酯或聚胺酯之聚合材料。The locking device 140 of FIG. 1 includes one or more brackets 150, a body 142, an arm 144, a handle 146, and a body 148. The bracket 150 of Figure 1 grips or is otherwise fastened to the inclined body 124 and slidably engages the body 142 of the locking device such that the body 142 can be forward relative to the inclined body 124 (in the proximal direction) Slide up and back (in the far direction). The bracket 150 of Figure 1 generally secures the body 142 in place while also providing sufficient frictional resistance to movement of the body 142 to prevent the locking device 140 from inadvertently sliding out of its locked position. The block 148 of FIG. 1 is coupled to the distal end of the body 142 and generally prevents the frame portion 110 from tilting relative to the base portion 120 when the locking device 140 is positioned in the locked position (because the block 148 supports the distal end 134 of the cantilever bracket 130, Limit the downward deflection of the cantilever bracket). In FIG. 1, block 148 is a support segment that approximates the height of the gap between the inclined body 126 and the unflexed cantilever bracket 130. Thus, when the locking device 140 of FIG. 1 is in its locked position (the block 148 is in the proximal position, wedged between the cantilever bracket 130 and the inclined body 126), the block 148 generally approximates the frame 114 and the mechanical shaft 125. The distal end 134 of the cantilever bracket 130 is aligned and sufficiently supported to limit downward deflection of the frame portion 110 relative to the rearwardly inclined base portion 120 of the seat. In FIG. 1, arm 144 is coupled to the proximal end of body 142 and extends downwardly from seat 112. Preferably, the arm 144 extends from the front of the seat 112, but it will be understood by those skilled in the art that the seat 100 can be configured such that the arm 144 extends out of one of the sides of the seat 112 or the back of the seat 112. . Regardless of the position of the arm 144 of Figure 1, a handle 146 can be mounted as appropriate to facilitate simple user actuation of the locking device 140 between the locked position and the unlocked position. Although not shown in FIGS. 1 and 2, the block 148 may also be configured with at least one liner 149 on its top and/or bottom surface. The liner 149 is typically made of a material that is softer than the material used in the inclined body 124 and/or the frame 114, and thus prevents the block 148 from scratching or denminating the inclined body 124 and/or the frame 114. Optionally, the liner can also be made of a material having a higher coefficient of friction to help secure the block in its locked position. In a particular embodiment, the liner 149 is a polymeric material such as polypropylene, polyester or polyurethane.
圖1、圖3、圖4、圖7及圖8展示處於未鎖定位置之鎖定設備140之各種視圖。在未鎖定位置，把手146經定位為相對接近於傾斜體124且可隱藏於座位112下。另外，當處於未鎖定位置時將塊體148定位為遠離框架114及傾斜體124之附近區域，以使得塊體148不阻礙框架部分110之傾斜運動。換言之，在未鎖定位置，塊體148不接觸懸臂支架130或傾斜體本體124中之至少一者以使得懸臂支架130之運動範圍(向下撓曲)不受塊體148限制。因此，當鎖定設備140處於未鎖定位置時，坐在座椅100中之人可向後靠在座位112之背部上或以其它方式向座位112之背部施加向後或向下之壓力來使框架部分110相對於基座部分120傾斜而無鎖定設備140來阻礙傾斜。1, 3, 4, 7, and 8 show various views of the locking device 140 in an unlocked position. In the unlocked position, the handle 146 is positioned relatively close to the inclined body 124 and can be hidden under the seat 112. Additionally, the block 148 is positioned away from the frame 114 and the vicinity of the inclined body 124 when in the unlocked position such that the block 148 does not obstruct the tilting movement of the frame portion 110. In other words, in the unlocked position, the block 148 does not contact at least one of the cantilever bracket 130 or the tilt body 120 such that the range of motion (downward deflection) of the cantilever bracket 130 is not limited by the block 148. Thus, when the locking device 140 is in the unlocked position, a person seated in the seat 100 can lean back against the back of the seat 112 or otherwise apply a rearward or downward pressure to the back of the seat 112 to cause the frame portion 110 to be depressed. Tilting relative to the base portion 120 without the locking device 140 to obstruct the tilt.
當坐在圖1之座椅100中之人希望防止座椅100傾斜時，該人藉由在向前方向上致動鎖定設備140而將鎖定設備140自未鎖定位置改變至鎖定位置。更特定言之，該人向前拉動把手146(在近端方向上)，此同樣使得臂144向前移動。臂144之向前運動使得鎖定設備之本體142向前穿過托架150滑動且將塊體148拉至框架114與傾斜體124之間的一位置。換言之，圖1之塊體148接觸懸臂支架130及傾斜體本體124兩者以使得懸臂支架130之運動範圍受到限制(阻礙遠端134向下撓曲之能力)。一般而言，在此致動過程期間，坐在座椅100中之人不應向後靠在座位112之背部上或以其它方式向座位112之背部施加向後或向下壓力。在一些情況中，對於鎖定設備140而言，甚至坐在座椅100中之人向前靠或以其它方式對座位112之背部施加向前或向上壓力為必要的，以充分致動處於未鎖定位置之鎖定設備140。When a person sitting in the seat 100 of FIG. 1 wishes to prevent the seat 100 from tilting, the person changes the locking device 140 from the unlocked position to the locked position by actuating the locking device 140 in the forward direction. More specifically, the person pulls the handle 146 forward (in the proximal direction), which also causes the arm 144 to move forward. The forward movement of the arm 144 causes the body 142 of the locking device to slide forward through the bracket 150 and pull the block 148 to a position between the frame 114 and the inclined body 124. In other words, the block 148 of FIG. 1 contacts both the cantilever bracket 130 and the tilt body 120 to limit the range of motion of the cantilever bracket 130 (the ability to obstruct the distal end 134 from flexing downward). In general, during this actuation process, a person sitting in the seat 100 should not lean back against the back of the seat 112 or otherwise apply rearward or downward pressure to the back of the seat 112. In some cases, it may be necessary for the locking device 140 to even forward or upwardly apply a forward or upward pressure to the back of the seat 112 by a person sitting in the seat 100 to fully actuate in an unlocked state. Position locking device 140.
圖2、圖5、圖6、圖9及圖10展示處於鎖定位置之鎖定設備140之各種視圖。在鎖定位置，把手146經定位為相對遠離傾斜體124且一般自座椅100下方伸出(如在圖6中所見)。另外，將圖2之塊體148定位於框架114與傾斜體124之間以使得塊體148藉由相對於基座部分豎直地固定懸臂支架之遠端134以使得遠端134無法向下撓曲而限制懸臂支架130之撓曲。因此在鎖定設備140之鎖定位置，其限制框架部分110相對於基座部分120(向後)傾斜，即使在坐於座椅100中之人可能向後靠在座位112之背部上或以其它方式向座位112之背部施加向後或向下壓力時亦是如此。2, 5, 6, 9, and 10 show various views of the locking device 140 in a locked position. In the locked position, the handle 146 is positioned relatively far away from the inclined body 124 and generally extends below the seat 100 (as seen in Figure 6). In addition, the block 148 of FIG. 2 is positioned between the frame 114 and the inclined body 124 such that the block 148 can securely lower the distal end 134 of the cantilevered bracket by vertically fixing the distal end 134 of the cantilevered bracket relative to the base portion. The curvature of the cantilever bracket 130 is limited. Thus in the locked position of the locking device 140, it limits the frame portion 110 from tilting relative to the base portion 120 (backward) even though the person sitting in the seat 100 may lean back against the back of the seat 112 or otherwise seat the seat The same applies to the back or downward pressure applied to the back of 112.
當坐在座椅100中之人希望使座椅100傾斜時，該人藉由在圖1中之向後方向上致動鎖定設備140而將鎖定設備140自鎖定位置改變至未鎖定位置。更特定言之，該人向後推動把手146，此同樣使臂144向後移動。臂144之向後運動使得本體142向後穿過托架150滑動且將塊體148推出遠離框架114與傾斜體124之間。一般而言，在此致動過程期間，坐在座椅100中之人不應向後靠在座位112之背部上或以其它方式向座位112之背部施加向後或向下壓力。在一些情況中，對於鎖定設備140而言，甚至坐在座椅100中之人向前靠或以其它方式對座位112之背部施加向前或向上壓力為必要的，以開始朝向未鎖定位置致動鎖定設備140。When a person sitting in the seat 100 wishes to tilt the seat 100, the person changes the locking device 140 from the locked position to the unlocked position by actuating the locking device 140 in the rearward direction in FIG. More specifically, the person pushes the handle 146 rearward, which also causes the arm 144 to move rearward. The rearward movement of the arms 144 causes the body 142 to slide back through the bracket 150 and push the block 148 away from between the frame 114 and the inclined body 124. In general, during this actuation process, a person sitting in the seat 100 should not lean back against the back of the seat 112 or otherwise apply rearward or downward pressure to the back of the seat 112. In some cases, it is necessary for the locking device 140 to even forward or otherwise apply a forward or upward pressure to the back of the seat 112 by a person sitting in the seat 100 to begin toward the unlocked position. The device 140 is locked.
圖11至圖15更為詳細地展示鎖定設備140。圖11及圖12說明鎖定設備140之塊體148、本體142、臂144及把手146。塊體148位於本體142之後側且可含有一孔(未圖示)以允許將襯墊149(示於圖3至圖6中)***至塊體148中。在將鎖定設備140安裝於基座部分120上時，本體142可相對於水平線傾斜以使得其大體上平行於傾斜體124之表面。該組態藉由最小化鎖定設備140之外觀而改良座椅100之美學外觀。另外，臂144可大體上水平，以使得當該人在鎖定位置與未鎖定位置之間致動臂144時，該臂144不接觸座位112。把手146附著至臂144之末端且可向上傾斜以改良鎖定設備140之人體工學及/或可操作性。必要時，可將裝飾性標識或用於致動鎖定設備140之指示壓印或以其他方式置放於把手146之正面上。視情況，把手可加以襯墊以改良人體工學。11 to 15 show the locking device 140 in more detail. 11 and 12 illustrate the block 148, body 142, arms 144, and handle 146 of the locking device 140. The block 148 is located on the rear side of the body 142 and may include a hole (not shown) to allow insertion of the liner 149 (shown in Figures 3-6) into the block 148. When the locking device 140 is mounted on the base portion 120, the body 142 can be inclined relative to the horizontal such that it is substantially parallel to the surface of the inclined body 124. This configuration improves the aesthetic appearance of the seat 100 by minimizing the appearance of the locking device 140. Additionally, the arm 144 can be generally horizontal such that the arm 144 does not contact the seat 112 when the person actuates the arm 144 between the locked position and the unlocked position. The handle 146 is attached to the end of the arm 144 and can be tilted upward to improve the ergonomics and/or operability of the locking device 140. If desired, the decorative logo or the indication for actuating the locking device 140 can be stamped or otherwise placed on the front side of the handle 146. The handle can be padded for improved ergonomics, as appropriate.
圖13至圖15說明鎖定設備140之托架150。此等圖式中之托架150使鎖定設備140之剩餘部分連接至傾斜體124且包含複數個夾具152、一下部導軌154及一上部導軌156。夾具152經組態以捲繞傾斜體124之諸側及下方，藉此將托架150緊固至傾斜體124。一般熟習此項技術者應瞭解托架150未必需要夾緊至傾斜體124。更正確地，托架150可藉由使用諸如螺桿、螺栓、焊接及/或黏著劑之任何合適附著手段而連接至框架部分110、基座部分120、懸臂支架130或三者之組合。下部導軌154經組態以與傾斜體124之上部表面一致且經定位於本體142之下以使得其充當本體142之下部支撐物。在一實施例中，本體142滑動跨越下部導軌154之上部表面之至少一部分。上部導軌156充當本體142之上部表面之導軌以使得本體142經定位於上部導軌156之至少一部分以下。在一實施例中，本體142藉由滑動跨越上部導軌156之下部表面之至少一部分而滑動穿過托架150。必要時，托架150可經組態有額外的下部導軌154或上部導軌156。因此，此等圖式之托架150可用來在豎直及水平方向上將鎖定設備140緊固於適當位置，同時使得本體142能夠自鎖定位置滑向未鎖定位置。13 through 15 illustrate the bracket 150 of the locking device 140. The bracket 150 in these figures connects the remainder of the locking device 140 to the ramp 124 and includes a plurality of clamps 152, a lower rail 154, and an upper rail 156. The clamp 152 is configured to wind the sides and underside of the inclined body 124, thereby fastening the bracket 150 to the inclined body 124. It will be appreciated by those skilled in the art that the bracket 150 does not necessarily need to be clamped to the angled body 124. More correctly, the bracket 150 can be coupled to the frame portion 110, the base portion 120, the cantilever bracket 130, or a combination of the three by any suitable attachment means such as a screw, bolt, weld, and/or adhesive. Lower rail 154 is configured to conform to the upper surface of ramp body 124 and is positioned below body 142 such that it acts as a lower support for body 142. In an embodiment, the body 142 slides across at least a portion of the upper surface of the lower rail 154. Upper rail 156 acts as a guide for the upper surface of body 142 such that body 142 is positioned below at least a portion of upper rail 156. In an embodiment, the body 142 slides through the bracket 150 by sliding across at least a portion of the lower surface of the upper rail 156. The bracket 150 can be configured with additional lower rails 154 or upper rails 156 as necessary. Thus, the brackets 150 of these figures can be used to secure the locking device 140 in place in the vertical and horizontal directions while enabling the body 142 to slide from the locked position to the unlocked position.
圖16至圖22說明輕便控制傾斜鎖定裝置之替代實施例。鎖定設備140之替代實施例類似於鎖定設備140之先前實施例，不同之處在於鎖定設備140之替代實施例含有複數個指狀物160作為托架150之替代。如在圖22中可見，將指狀物160定位於本體142之兩側以及本體142之頂部表面及底部表面上。必要時，鎖定設備140可經組態有與圖式中所示相比更多的指狀物160。在將鎖定設備140安裝於座椅100上時，指狀物160在懸臂支架130中之每一者以上及以下延伸且使鎖定設備140保持定位於懸臂支架130之間。指狀物160亦允許鎖定設備140沿懸臂支架130向前或向後滑動。鎖定設備140沿懸臂支架130之行進可在向前方向上由傾斜體124之頭部127限制且在向後方向上由框架114限制。較佳地，鎖定設備140之替代實施例經組態以使得鎖定設備140在指狀物160接觸頭部127時處於鎖定位置且在指狀物160接觸框架114時處於未鎖定位置。然而，一般熟習此項技術者應瞭解鎖定設備140之替代實施例可經組態以使得鎖定設備140在指狀物160接觸頭部127時處於未鎖定位置且在指狀物160接觸框架114時處於鎖定位置。16 through 22 illustrate an alternate embodiment of a lightweight control tilt lock. An alternate embodiment of the locking device 140 is similar to the previous embodiment of the locking device 140, except that an alternate embodiment of the locking device 140 includes a plurality of fingers 160 as an alternative to the bracket 150. As can be seen in Figure 22, the fingers 160 are positioned on both sides of the body 142 and on the top and bottom surfaces of the body 142. If desired, the locking device 140 can be configured with more fingers 160 than shown in the drawings. When the locking device 140 is mounted on the seat 100, the fingers 160 extend above and below each of the cantilever brackets 130 and maintain the locking device 140 positioned between the cantilever brackets 130. The fingers 160 also allow the locking device 140 to slide forward or backward along the cantilever bracket 130. The travel of the locking device 140 along the cantilever bracket 130 can be limited by the head 127 of the inclined body 124 in the forward direction and by the frame 114 in the rearward direction. Preferably, an alternate embodiment of the locking device 140 is configured such that the locking device 140 is in the locked position when the finger 160 contacts the head 127 and is in the unlocked position when the finger 160 contacts the frame 114. However, those skilled in the art will appreciate that alternative embodiments of the locking device 140 can be configured such that the locking device 140 is in an unlocked position when the fingers 160 contact the head 127 and when the fingers 160 contact the frame 114 In the locked position.
