Description

百葉簾 Venetian blinds

本創作是有關於一種百葉簾，特別是一種透過薄型帶狀物的捲放來展開或收合的無拉繩式百葉簾。 This creation relates to a kind of blind, especially a cordless blind that can be unfolded or folded by rolling up a thin strip.

一般的無拉繩式百葉簾包含一上梁、一下梁、多個葉片、至少一對梯繩及至少一對升降拉繩。其中，各梯繩由前後排列設置的一對經線以及設在該二經線之間的多個緯線所組成並呈梯格狀，該等葉片分別承靠在該等緯線上而設置在各梯格中。當各梯繩的該對經線其中一者向上移動且另一者向下移動，該等緯線帶動該等葉片傾斜，使該等葉片可以在一水平狀態及一閉合狀態之間切換。該二升降拉繩分別鄰近該對梯繩的位置設置。各升降拉繩的上端固接在上梁中一升降控制機構的一捲線軸，下端則在穿過該等葉片的穿孔之後連接下梁，藉此將下梁懸吊在該上梁的下方。同時，各升降拉繩隨著該百葉簾被收合或展開而被該捲線軸捲收或釋放。 A typical cordless blind includes an upper beam, a lower beam, a plurality of blades, at least one pair of ladder ropes and at least one pair of lifting ropes. Wherein, each ladder rope is composed of a pair of warp threads arranged front and back and a plurality of weft threads arranged between the two warp threads and is in the shape of a ladder. The blades are respectively supported on the weft threads and are arranged on each side. In the ladder grid. When one of the pair of warp lines of each ladder rope moves upward and the other moves downward, the weft lines drive the blades to tilt, so that the blades can switch between a horizontal state and a closed state. The two lifting ropes are respectively arranged adjacent to the position of the pair of ladder ropes. The upper end of each lifting rope is fixed to a spool of a lifting control mechanism in the upper beam, and the lower end is connected to the lower beam after passing through the perforations of the blades, thereby suspending the lower beam below the upper beam. At the same time, each lifting rope is retracted or released by the reel as the blind is folded or unfolded.

然而，當該等葉片處於該閉合狀態時，各葉片並無法翻轉至完全的垂直狀態，因為該二升降拉繩會被夾在每對相鄰的葉片之間，形成線徑大小的間隔，造成一定的漏光量，使百葉簾未能完全遮蔽光線。除此之外，當各升降拉繩被捲收而纏繞在該捲線軸上時，無法確保每一繞圈會 依序整齊排列在上一繞圈旁邊，造成該二升降拉繩被捲線軸捲收的部分並不等長，進而使該二升降拉繩在上梁及下梁之間的長度不一致，導致下梁無法保持水平狀態而左右歪斜，造成視覺上不美觀。 However, when the blades are in the closed state, each blade cannot be flipped to a completely vertical state because the two lifting ropes will be sandwiched between each pair of adjacent blades, forming a distance of a wire diameter, resulting in A certain amount of light leakage prevents the venetian blinds from completely blocking the light. In addition, when each lifting rope is taken up and wound on the spool, there is no guarantee that each turn will They are arranged neatly next to the previous circle in sequence, causing the parts of the two lifting ropes to be rolled up by the reels to be unequal lengths. This further causes the lengths of the two lifting ropes to be inconsistent between the upper beam and the lower beam, causing the lower beam to be lowered. The beam cannot maintain a horizontal state and is skewed from side to side, resulting in a visually unsightly appearance.

更甚者，該二升降拉繩在長期懸吊下梁及操作的過程中，會因重力或手拉力拉扯的影響而逐漸地延展變形。若該二升降拉繩的變形值不同會造成下梁歪斜。在該無拉繩式百葉簾共具有三條升降拉繩的狀況下，位在中間的升降拉繩會因受力最大而延展伸長的程度較位在旁邊兩側的升降拉繩更為嚴重，致使下梁被該三升降拉繩懸吊時會呈拱形，無法以水平狀態被收合而貼平在該等葉片下方，影響該無拉繩式百葉簾的整體外觀。 What's more, the two lifting ropes will gradually expand and deform due to the influence of gravity or hand pulling during long-term suspension and operation of the lower beam. If the deformation values of the two lifting ropes are different, the lower beam will be skewed. When the cordless blinds have a total of three lift cords, the lift cord in the middle will stretch to a greater extent due to the greatest force than the lift cords on the sides, resulting in When the lower beam is suspended by the three lifting cords, it will be arched and cannot be folded in a horizontal state and will lie flat under the blades, affecting the overall appearance of the cordless blind.

有鑑於上述習知的問題，本創作的其中一目的在於提供一種透過薄型帶狀物的捲放來展開或收合的百葉簾，閉合後葉片之間的縫隙較小、遮光效果較佳，且在收合過程中可確保下梁維持水平狀態而不致歪斜。 In view of the above-mentioned conventional problems, one of the purposes of this invention is to provide a venetian blind that can be unfolded or folded by rolling a thin strip. After closing, the gap between the blades is smaller, the light-shielding effect is better, and During the folding process, it can be ensured that the lower beam remains level and does not tilt.

根據本創作的目的，提供一種百葉簾，包含有一上梁、一下梁、至少二梯繩、複數個葉片、至少二升降拉帶以及一升降控制機構。各葉片具有一第一穿孔及一第二穿孔。升降控制機構包含有一驅動輪、一渦卷彈簧及至少一捲帶輪，該渦卷彈簧的一端連接該驅動輪以隨該驅動輪的轉動方向不同而捲繞在或釋出自該驅動輪，該至少一捲帶輪連接該驅動輪並與該驅動輪平行設置。其中，當該驅動輪及該捲帶輪其中一者轉動會驅使另一者同步轉動。各捲帶輪具有至少一個環形槽道，且在該升降控制機 構中配置成該環形槽道的數量至少為二或二以上以足夠供該等升降拉帶分別對應設置。各環形槽道的寬度對應各該升降拉帶的寬邊。各升降拉帶分別捲繞在或釋出自各環形槽道，且各升降拉帶的每一繞圈大致對齊並且疊在另一繞圈上方。 According to the purpose of this invention, a blind is provided, which includes an upper beam, a lower beam, at least two ladder ropes, a plurality of blades, at least two lifting straps and a lifting control mechanism. Each blade has a first through hole and a second through hole. The lifting control mechanism includes a driving wheel, a scroll spring and at least one winding pulley. One end of the scroll spring is connected to the driving wheel to be wound around or released from the driving wheel according to the rotation direction of the driving wheel. At least one pulley is connected to the driving wheel and is arranged parallel to the driving wheel. Wherein, when one of the driving wheel and the take-up wheel rotates, the other will be driven to rotate synchronously. Each pulley has at least one annular channel, and in the lifting control machine The number of the annular channels configured in the structure is at least two or more, which is enough for the lifting straps to be arranged correspondingly. The width of each annular channel corresponds to the wide side of each lift strap. Each lift strap is wound around or released from each annular channel, and each turn of each lift strap is generally aligned and stacked on top of another turn.

當該百葉簾被展開，該二升降拉帶從該捲帶輪釋出，因而帶動該捲帶輪朝一第一方向轉動，進而帶動該驅動輪正向轉動，使該渦卷彈簧捲繞至該驅動輪上並蓄積一彈力。當該百葉簾被收合，該渦卷彈簧釋放該彈力，從該驅動輪釋出。該渦卷彈簧帶動該驅動輪反向轉動，進而帶動該捲帶輪朝與一第二方向轉動，捲收該二升降拉帶。其中，該第二方向與該第一方向為相反方向。 When the blinds are unfolded, the two lifting straps are released from the take-up wheel, thereby driving the take-up wheel to rotate in a first direction, and then driving the driving wheel to rotate forward, so that the scroll spring is wound to the on the driving wheel and accumulates an elastic force. When the blind is folded, the scroll spring releases the elastic force and is released from the driving wheel. The scroll spring drives the driving wheel to rotate in the opposite direction, and then drives the take-up wheel to rotate in a second direction to retract the two lifting straps. Wherein, the second direction and the first direction are opposite directions.

在本創作之一實施例中，該百葉簾更包含至少二轉向裝置設在該上梁，各轉向裝置包含一第一弧形元件、一底座及一第二弧形元件，其中，該第一弧形元件具有至少一弧面，該第二弧形元件包含至少一弧形件設於該底座。該二升降拉帶從該升降控制機構延伸出後，分別繞過該二轉向裝置的第一弧形元件的弧面，並各自沿一傳輸方向延伸至並繞過所對應的轉向裝置的該第二弧形元件，再由該上梁穿出。此後，該二升降拉帶分別朝該等葉片的該等第一穿孔及該等第二穿孔延伸。 In one embodiment of the invention, the blind further includes at least two steering devices located on the upper beam. Each steering device includes a first arc-shaped element, a base and a second arc-shaped element, wherein the first The arc-shaped element has at least one arc surface, and the second arc-shaped element includes at least one arc-shaped piece disposed on the base. After the two lifting straps extend from the lifting control mechanism, they respectively bypass the arc surfaces of the first arc-shaped elements of the two steering devices, and each extend along a transmission direction to and bypass the corresponding third steering device. The two arc-shaped components pass through the upper beam. Thereafter, the two lifting straps respectively extend toward the first through holes and the second through holes of the blades.

較佳者，第一弧形元件為一對滾筒，各滾筒具有一弧面。各升降拉繩從該升降控制機構延伸出後，依序繞過該二滾筒的該二弧面。 Preferably, the first arc-shaped element is a pair of rollers, each roller having an arc surface. After each lifting rope extends from the lifting control mechanism, it goes around the two arc surfaces of the two rollers in sequence.

較佳者，各弧形件為一定位滾輪，其軸向兩端分別具有一凸垣，其軸向中央具有一凹陷部位在該二凸垣之間，使各升降拉帶在繞過該 定位滾輪時會被該二凸垣限制在該凹陷部。 Preferably, each arc-shaped member is a positioning roller, with a convex wall at both axial ends, and a recessed portion in the axial center between the two convex walls, so that each lifting strap can bypass the two convex walls. When positioning the roller, it will be restricted by the two convex walls in the recessed portion.

較佳者，該第二弧形元件的弧形件選擇性地安裝在該底座上的一第一位置或一第二位置。其中，該第一弧形元件沿該傳輸方向至該第一位置的距離，小於該第一弧形元件沿該傳輸方向至該第二位置的距離。當該弧形件安裝在該第二位置，該第二弧形元件進一步包含一輔助件。各升降拉帶在繞過該第一弧形元件的弧面之後，依序繞過該弧形件及該輔助件，再由該上梁穿出。 Preferably, the arc-shaped part of the second arc-shaped element is selectively installed at a first position or a second position on the base. Wherein, the distance from the first arc-shaped element along the transmission direction to the first position is smaller than the distance from the first arc-shaped element along the transmission direction to the second position. When the arc-shaped component is installed in the second position, the second arc-shaped component further includes an auxiliary component. After each lifting strap goes around the arc surface of the first arc-shaped element, it goes around the arc-shaped component and the auxiliary component in sequence, and then passes out of the upper beam.

在本創作之一實施例中，該上梁更包含一透光調整機構，以控制各梯繩的該二經線上下錯位，進而帶動該等葉片在一水平位置和一閉合位置之間翻轉。該上梁的一側邊定義一側向基準面。該二梯繩其中一者的該二經線從該上梁底面穿出的位置，與該側向基準面間隔一第一距離；該二梯繩中另一者的該二經線從該上梁底面穿出的位置，與該側向基準面間隔一第二距離；該二升降拉帶其中一者從該上梁底面穿出的位置，與該側向基準面間隔一第三距離；該二升降拉帶中另一者從該上梁底面穿出的位置，與該側向基準面間隔一第四距離。其中，上述的該第一距離、該第二距離、該第三距離及該第四距離實質上皆不相同。 In one embodiment of the invention, the upper beam further includes a light transmission adjustment mechanism to control the up and down misalignment of the two warp lines of each ladder rope, thereby driving the blades to flip between a horizontal position and a closed position. One side of the upper beam defines a lateral datum. The position where the two warp threads of one of the two ladder ropes passes through the bottom surface of the upper beam is separated from the lateral reference plane by a first distance; the two warp threads of the other of the two ladder ropes pass from the upper beam. The position where the bottom surface of the beam penetrates is separated from the lateral datum plane by a second distance; the position where one of the two lifting straps penetrates from the bottom surface of the upper beam is separated by a third distance from the lateral datum plane; The position where the other of the two lifting straps passes through the bottom surface of the upper beam is spaced a fourth distance from the lateral reference plane. Wherein, the above-mentioned first distance, the second distance, the third distance and the fourth distance are substantially different.

在本創作之一實施例中，本創作的百葉簾在使用上至少具有以下優點： In one embodiment of this invention, the venetian blinds of this invention have at least the following advantages in use:

(1)本創作的百葉簾在閉合狀態下，每二個相鄰葉片之間夾著薄型的升降拉帶所形成的間隔，其寬度小於有著較大線徑的一般繩索會形成的間隔的寬度。因此，本創作的百葉簾閉合後遮光效果較佳。 (1) When the venetian blinds of this invention are in the closed state, the space formed by the thin lifting straps sandwiched between each two adjacent blades is smaller than the width of the space formed by ordinary ropes with larger wire diameters. . Therefore, the blinds of this invention have a better light-blocking effect after being closed.

(2)由於本創作的百葉簾的各升降拉帶整齊地疊繞在捲帶輪的各環形槽道上，本創作的百葉簾在捲收該二升降拉帶的過程中可確保該二升降拉帶在上梁及下梁之間的長度一致，進而使下梁維持水平狀態而不致歪斜。 (2) Since the lifting straps of the blinds of the present invention are neatly wound on each annular channel of the winding wheel, the blinds of the present invention can ensure that the two lifting straps are rolled up during the process of rolling up the two lifting straps. The length of the belt between the upper beam and the lower beam is the same, thereby keeping the lower beam in a horizontal state without being skewed.

(3)本創作的百葉簾的轉向裝置中的第二弧形元件的弧形件，在組裝階段可選擇性安裝在底座上的不同位置並在安裝在一第二位置時搭配輔助件使用，藉此提供可調整阻力，使該轉向裝置可同時適用在不同規格的百葉簾產品。 (3) The arc-shaped part of the second arc-shaped element in the turning device of the blinds of the present invention can be selectively installed at different positions on the base during the assembly stage and used with auxiliary parts when installed in a second position. This provides adjustable resistance, so that the steering device can be applied to venetian blind products of different specifications at the same time.

(4)本創作的百葉簾的該等升降拉帶及該等經線通過上梁的位置相互錯開，可避免升降拉帶接觸、割損經線。 (4) The position of the lifting straps and the warp threads passing through the upper beam of the blinds of this invention are staggered from each other, which can prevent the lifting straps from contacting and cutting the warp threads.

(5)本創作的百葉簾的該等升降拉帶長期受力也不易延展變形，可避免長期使用後拉繩變形而導致下梁歪斜的問題。 (5) The lifting straps of the blinds of this invention are not easy to stretch and deform under long-term stress, which can avoid the problem of the lower beam being skewed due to deformation of the straps after long-term use.

該等葉片4分別承靠在該等梯繩3的該等支撐件33上而排列設置在該上梁1及該下梁2之間。各葉片4上開設一第一穿孔41以及一第二穿孔42，其沿該葉片4一縱向長邊的延伸方向分布在該葉片4上靠近二端處。如圖1A所示，該二升降拉帶5分別為一薄型帶狀物，具有一寬邊BS及一窄 邊NS，其材質可選用金屬(例如：鋁)、塑膠(例如：PET)或塑鋼。該二升降拉帶5的下端分別穿過該等葉片4的該等第一穿孔41以及該等第二穿孔42並固定地連接該下梁2。值得注意的是，相較於編織繩，該二升降拉帶5的形狀和材質能使其更能承受該百葉簾100的構件的施力而不易延展變形。換言之，即使該百葉簾100長期維持展開狀態以該二升降拉帶5懸掛該下梁2使用，或長期承受人力向下拉動下梁2，該二升降拉帶5的縱向長度也不易發生變化，因而確保了該下梁2能夠維持水平狀態不致歪斜。 The blades 4 respectively bear on the supports 33 of the ladder ropes 3 and are arranged between the upper beam 1 and the lower beam 2 . Each blade 4 is provided with a first through hole 41 and a second through hole 42, which are distributed near the two ends of the blade 4 along the extension direction of one longitudinal side of the blade 4. As shown in Figure 1A, the two lifting straps 5 are respectively thin strips with a wide side BS and a narrow side. Side NS can be made of metal (for example: aluminum), plastic (for example: PET) or plastic steel. The lower ends of the two lifting straps 5 respectively pass through the first through holes 41 and the second through holes 42 of the blades 4 and are fixedly connected to the lower beam 2 . It is worth noting that compared with braided ropes, the shape and material of the two lifting straps 5 can better withstand the force exerted by the components of the venetian blind 100 and not be easily stretched and deformed. In other words, even if the venetian blind 100 is maintained in the unfolded state for a long time and used with the two lifting straps 5 suspended from the lower beam 2, or is subjected to manual force to pull the lower beam 2 downward for a long time, the longitudinal length of the two lifting straps 5 is not easy to change. This ensures that the lower beam 2 can maintain a horizontal state without being skewed.

在本實施例中，該第一穿孔41以及該第二穿孔42分別為沿各葉片4的一橫向短邊的延伸方向所開設之一長型孔。如圖1A所示，該長型孔具有一短邊SS及一長邊LS，該短邊SS的長度稍大於各升降拉帶5的寬邊BS的長度，以容納各升降拉帶5穿過其中。其中，當各升降拉帶5穿過各長型孔，各升降拉帶5的寬邊BS大致平行於各葉片4的一縱向長邊的延伸方向，且各升降拉帶5的寬邊BS的兩側距離該長型孔內緣各約0.5公厘。 In this embodiment, the first through hole 41 and the second through hole 42 are respectively elongated holes opened along the extending direction of a transverse short side of each blade 4 . As shown in Figure 1A, the elongated hole has a short side SS and a long side LS. The length of the short side SS is slightly larger than the length of the wide side BS of each lifting strap 5 to accommodate the passage of each lifting strap 5. in. Among them, when each lifting strap 5 passes through each elongated hole, the wide side BS of each lifting strap 5 is substantially parallel to the extending direction of a longitudinal long side of each blade 4, and the wide side BS of each lifting strap 5 is The distance between both sides of the elongated hole is about 0.5 mm from the inner edge of the elongated hole.

該升降控制機構6用以控制該等升降拉帶5的捲收及釋放，可設置在上梁1或下梁2。該二轉向裝置7用來改變該二升降拉帶5的延伸方向，且隨同該升降控制機構6一起設置在上梁1或下梁2。 The lifting control mechanism 6 is used to control the retraction and release of the lifting straps 5 and can be installed on the upper beam 1 or the lower beam 2 . The two steering devices 7 are used to change the extension direction of the two lifting straps 5 and are arranged on the upper beam 1 or the lower beam 2 together with the lifting control mechanism 6 .

請參閱圖4至圖6，在本實施例中，升降控制機構6設置在上梁1之中，且包含有一基座61、一驅動輪62、一儲簧輪63、一渦卷彈簧64、一捲帶輪65以及複數個導引滾輪66。較佳者，升降控制機構6更包含一蓋板6a(顯示在圖1)設在基座61上方。該基座61具有三個軸柱611、612及613，其分別沿平行該第一軸向A1之一方向延伸(如圖9所示)，且該儲簧輪63、 該驅動輪62的輪體以及該捲帶輪65的輪體分別套設於其上。該渦卷彈簧64的二端分別連接儲簧輪63及驅動輪62的輪體，且會依該驅動輪62轉動方向不同而捲收至或釋出自該驅動輪62的輪體。又，該驅動輪62的輪體下方的齒盤嚙接該捲帶輪65的輪體下方的齒盤，使該驅動輪62與該捲帶輪65相互連接且沿一平行方向設置，且當該驅動輪62及該捲帶輪65其中一者轉動會驅使另一者同步轉動。其中，該捲帶輪65具有二個環形槽道651、652以供該二升降拉帶5的上端分別固定並捲繞於其上。該等導引滾輪66鄰近該捲帶輪65設置於該基座61上，係用以改變該二升降拉帶5的延伸方向。 Please refer to Figures 4 to 6. In this embodiment, the lifting control mechanism 6 is provided in the upper beam 1 and includes a base 61, a driving wheel 62, a spring storage wheel 63, a scroll spring 64, A pulley 65 and a plurality of guide rollers 66. Preferably, the lifting control mechanism 6 further includes a cover 6a (shown in FIG. 1 ) located above the base 61 . The base 61 has three shaft columns 611, 612 and 613, which respectively extend in a direction parallel to the first axis A1 (as shown in Figure 9), and the spring storage wheel 63, The wheel body of the driving wheel 62 and the wheel body of the take-up pulley 65 are respectively sleeved thereon. The two ends of the scroll spring 64 are connected to the spring storage wheel 63 and the wheel body of the driving wheel 62 respectively, and will be retracted or released from the wheel body of the driving wheel 62 according to the rotation direction of the driving wheel 62 . In addition, the toothed disc under the wheel body of the driving wheel 62 engages the toothed disc under the wheel body of the take-up pulley 65, so that the driving wheel 62 and the take-up pulley 65 are connected to each other and arranged in a parallel direction, and when The rotation of one of the driving wheel 62 and the take-up wheel 65 will drive the other to rotate synchronously. The take-up pulley 65 has two annular grooves 651 and 652 for the upper ends of the two lifting straps 5 to be respectively fixed and wound on. The guide rollers 66 are disposed on the base 61 adjacent to the take-up wheel 65 and are used to change the extending direction of the two lifting straps 5 .

請參閱圖7，該捲帶輪65的該二環形槽道651、652其中每一者沿該第一軸向A1的寬度W1，僅稍大於各升降拉帶5的寬邊BS的長度W2。更具體而言，各環形槽道651或652的寬度W1大於各升降拉帶5的寬邊BS的長度W2，並同時小於2倍的各升降拉帶5的寬邊BS的長度W2，以避免各升降拉帶5的每一繞圈在疊繞在另一繞圈上方時沿該第一軸向A1滑動位移。較佳者，該寬度W1為約1.5倍的各升降拉帶5的寬邊BS的長度W2。因此，當各升降拉帶5捲繞在所對應的環形槽道651或652上時，其每一繞圈得以大致對齊並且疊置在另一繞圈上方。有別於習知升降拉繩只能以不規律的方式纏繞在捲線軸上，此種整齊的疊繞方式可確保該二升降拉帶5被該捲帶輪65捲收的長度一致，進而確保下梁2在上升的過程中維持水平狀態。 Referring to FIG. 7 , the width W1 of each of the two annular grooves 651 and 652 of the take-up pulley 65 along the first axis A1 is only slightly larger than the length W2 of the wide side BS of each lifting strap 5 . More specifically, the width W1 of each annular channel 651 or 652 is greater than the length W2 of the wide side BS of each lifting strap 5, and at the same time is less than 2 times the length W2 of the wide side BS of each lifting strap 5, so as to avoid Each turn of each lifting strap 5 slides and displaces along the first axis A1 when being stacked on top of another turn. Preferably, the width W1 is about 1.5 times the length W2 of the wide side BS of each lifting strap 5 . Therefore, when each lift strap 5 is wound around the corresponding annular channel 651 or 652, each turn thereof is substantially aligned and stacked above the other turn. Different from the conventional lifting ropes that can only be wound on the reel in an irregular manner, this neat overlapping method can ensure that the lengths of the two lifting ropes 5 rolled up by the winding pulley 65 are consistent, thereby ensuring The lower beam 2 maintains a horizontal state during the rising process.

請參閱圖8，該導引滾輪66具有三個盤狀物沿該第一軸向A1間隔設置，該等盤狀物中相鄰二者之間形成一第一槽道661以及一第二槽道662。 Please refer to FIG. 8 . The guide roller 66 has three disks spaced apart along the first axis A1 . A first channel 661 and a second groove are formed between two adjacent disks. Road 662.

請回頭參閱圖6，該二升降拉帶5從該捲帶輪65延伸出之後，其中一升降拉帶5對應地繞過該等導引滾輪66的第一槽道661而改變延伸方向，另一升降拉帶5則對應地繞過該等導引滾輪66的第二槽道662而改變延伸方向。此後，該二升降拉帶5分別經過該二轉向裝置7，並再次被改變延伸方向而沿該第一軸向A1延伸至下梁2。 Please refer back to FIG. 6 . After the two lifting straps 5 extend from the take-up pulley 65 , one of the lifting straps 5 correspondingly bypasses the first grooves 661 of the guide rollers 66 to change its extension direction. A lifting belt 5 accordingly bypasses the second grooves 662 of the guide rollers 66 and changes its extension direction. Thereafter, the two lifting straps 5 pass through the two steering devices 7 respectively, and are changed in their extension direction again to extend to the lower beam 2 along the first axial direction A1.

請參閱圖4至圖6，當使用者欲將已收合的該百葉簾100(顯示於圖5)展開而下拉下梁2，該等葉片4逐漸被展開，且該二升降拉帶5隨著下梁2的移動分別從該捲帶輪65的該二環形槽道651、652上釋出。此時，該捲帶輪65被該等升降拉帶5帶動而朝一第一方向(例如：圖6中所示之順時針方向)轉動，進而帶動該驅動輪62正向(例如：圖6中所示之逆時針方向)轉動，使該渦卷彈簧64捲繞至該驅動輪62上並蓄積一彈力。 Referring to Figures 4 to 6, when the user wants to unfold the folded venetian blind 100 (shown in Figure 5) and pulls down the lower beam 2, the blades 4 are gradually unfolded, and the two lifting straps 5 follow. The movement of the lower beam 2 is released from the two annular grooves 651 and 652 of the pulley 65 respectively. At this time, the take-up pulley 65 is driven by the lifting straps 5 to rotate in a first direction (for example, the clockwise direction as shown in FIG. 6 ), and then drives the driving wheel 62 in the forward direction (for example, as shown in FIG. 6 (as shown in the counterclockwise direction), the scroll spring 64 is wound around the driving wheel 62 and accumulates an elastic force.

相對地，當使用者欲收合該百葉簾100而上抬下梁2，該等葉片4逐漸被收合，且該渦卷彈簧64因為該下梁2的移動破壞百葉簾100整體平衡而釋放先前所蓄積的彈力，從該驅動輪62釋出並捲繞回該儲簧輪63上。該驅動輪62被渦卷彈簧64帶動而反向轉動，進而帶動該捲帶輪65朝與該第一方向相反之一第二方向轉動，並使該二升降拉帶5分別捲繞在該二環形槽道651、652上。 Correspondingly, when the user wants to close the venetian blind 100 and lifts the lower beam 2, the blades 4 are gradually closed, and the scroll spring 64 is released because the movement of the lower beam 2 destroys the overall balance of the venetian blind 100. The previously accumulated elastic force is released from the driving wheel 62 and wound back to the spring storage wheel 63 . The driving wheel 62 is driven by the scroll spring 64 to rotate in the opposite direction, thereby driving the winding wheel 65 to rotate in a second direction opposite to the first direction, and the two lifting straps 5 are wound around the two lifting straps 5 respectively. On the annular channels 651 and 652.

請參閱圖9及圖10。升降控制機構6更包含一阻力機構67，其可連動地連接該捲帶輪65，以在該捲帶輪65朝該第一方向轉動時對該捲帶輪65提供阻力。在本實施例中，該阻力機構67包含一摩擦件671、一第一限位件672及一第二限位件673，該摩擦件671為彈性材質所製成的一封閉環體 並套設在軸柱612上，該第一限位件672設在該摩擦件671外圍且具有多個懸臂6721朝外徑向凸伸，該第二限位件673為該驅動輪62下方齒盤的內齒圈，其對應該第一限位件672的外圍設置且具有複數個棘齒對應該等懸臂6721設置。 Please refer to Figure 9 and Figure 10. The lifting control mechanism 6 further includes a resistance mechanism 67 that is operatively connected to the take-up pulley 65 to provide resistance to the take-up pulley 65 when the take-up pulley 65 rotates in the first direction. In this embodiment, the resistance mechanism 67 includes a friction member 671, a first limiting member 672 and a second limiting member 673. The friction member 671 is a closed ring made of elastic material. And sleeved on the shaft column 612, the first limiting member 672 is provided on the periphery of the friction member 671 and has a plurality of cantilevers 6721 protruding radially outward, and the second limiting member 673 is the lower tooth of the driving wheel 62. The inner ring gear of the disk is arranged corresponding to the periphery of the first limiting member 672 and has a plurality of ratchet teeth arranged corresponding to the cantilevers 6721 .

當使用者展開百葉簾100而使捲帶輪65朝第一方向(例如：圖10中所示逆時針方向)轉動並帶動該驅動輪62正向(例如：圖10中所示順時針方向)轉動時，第二限位件673會相對第一限位件672轉動，直到第一限位件672的懸臂6721卡抵於第二限位件673的棘齒為止。此後，第二限位件673會帶動第一限位件672同步轉動，使第一限位件672相對摩擦件671產生摩擦力、或第一限位件672帶動摩擦件671相對軸柱612轉動而產生摩擦力。藉此，該阻力機構67對驅動輪62的轉動提供摩擦力，並因為捲帶輪65連接驅動輪62，該阻力機構67亦間接對該捲帶輪65的轉動提供摩擦力。在本創作其他實施例中，阻力機構亦可設置在該捲帶輪65及該軸柱613上並直接對該捲帶輪65的轉動提供摩擦力。 When the user unfolds the blind 100, the take-up wheel 65 rotates in the first direction (for example, the counterclockwise direction as shown in Figure 10) and drives the driving wheel 62 in the forward direction (for example, the clockwise direction as shown in Figure 10) When rotating, the second limiting member 673 will rotate relative to the first limiting member 672 until the cantilever 6721 of the first limiting member 672 engages the ratchet of the second limiting member 673 . Thereafter, the second limiter 673 will drive the first limiter 672 to rotate synchronously, so that the first limiter 672 generates friction force relative to the friction member 671, or the first limiter 672 drives the friction member 671 to rotate relative to the shaft column 612. And produce friction. Thereby, the resistance mechanism 67 provides friction force for the rotation of the driving wheel 62 , and because the take-up pulley 65 is connected to the driving wheel 62 , the resistance mechanism 67 also indirectly provides friction force for the rotation of the take-up pulley 65 . In other embodiments of the present invention, the resistance mechanism can also be disposed on the take-up pulley 65 and the shaft column 613 and directly provide friction for the rotation of the take-up pulley 65 .

更甚者，該阻力機構67提供的是單向的阻力。換言之，該阻力機構67僅在該捲帶輪65朝該第一方向轉動時，對該捲帶輪65的轉動提供阻力。當該捲帶輪65朝該第二方向轉動時，該阻力機構67並不會對該捲帶輪65的轉動提供阻力。具體而言，當使用者收合百葉簾100而使該捲帶輪65朝與第一方向相反之第二方向轉動並帶動該驅動輪62反向轉動時，第二限位件673會相對第一限位件672轉動。此時，該第一限位件672的懸臂6721自該等棘齒之間脫離而依序從該等棘齒的齒頂滑過，使第一限位件672不會隨 著第二限位件673同步轉動，且第一限位件672與摩擦件671之間、摩擦件671與軸柱612之間均無相對運動。換言之，此時該第一限位件672和摩擦件671均不會對該第二限位件673的轉動產生摩擦力。 What's more, the resistance mechanism 67 provides one-way resistance. In other words, the resistance mechanism 67 only provides resistance to the rotation of the take-up pulley 65 when the take-up pulley 65 rotates in the first direction. When the take-up pulley 65 rotates in the second direction, the resistance mechanism 67 does not provide resistance to the rotation of the take-up pulley 65 . Specifically, when the user closes the venetian blind 100 and causes the take-up pulley 65 to rotate in the second direction opposite to the first direction and drive the driving wheel 62 to rotate in the opposite direction, the second limiting member 673 will move relative to the first direction. A limiting member 672 rotates. At this time, the cantilever 6721 of the first limiting member 672 detaches from between the ratchet teeth and sequentially slides through the tooth tops of the ratchet teeth, so that the first limiting member 672 does not follow the ratchet teeth. The second limiting member 673 rotates synchronously, and there is no relative movement between the first limiting member 672 and the friction member 671, or between the friction member 671 and the shaft column 612. In other words, at this time, neither the first limiting member 672 nor the friction member 671 will generate frictional force on the rotation of the second limiting member 673 .

本創作之百葉簾的梯繩以及升降拉帶的數量不以上述舉例為限，可配置二個以上的梯繩及/或升降拉帶以配合幅寬更大的百葉簾。惟，至少須配置二個梯帶及二個升降拉帶以確保該等葉片均勻受力，而為了對應該等升降拉帶的數量，本創作之百葉簾之升降控制機構被配置為包含二或二以上個環形槽道，以使該等升降拉帶有足夠的環形槽道對應設置。 The number of ladder ropes and lifting straps of the blinds of this invention is not limited to the above examples. More than two ladder ropes and/or lifting straps can be configured to match the larger width of the blinds. However, at least two ladder straps and two lifting straps must be configured to ensure that the blades are evenly stressed.

舉例而言，在前述實施例中，升降控制機構6包含一個捲帶輪65，且該捲帶輪65具有二個環形槽道651、652以供該二升降拉帶5分別對應設置。然而，在升降拉帶數量為二的前提之下，升降控制機構亦可配置為包含二個分別具有一個環形槽道的捲帶輪，如此亦能提供共二個環形槽道供該二升降拉帶分別對應設置。另外，若升降拉帶的數量大於二，亦可透過增加捲帶輪的數量或在單一捲帶輪上開設更多個環形槽道，藉此擴充升降控制機構所擁有的環形槽道的總數，使其足夠供該等升降拉繩對應設置。以下將配合多個實施例詳細說明。 For example, in the aforementioned embodiment, the lifting control mechanism 6 includes a take-up pulley 65, and the take-up pulley 65 has two annular grooves 651 and 652 for the two lifting straps 5 to be respectively disposed correspondingly. However, on the premise that the number of lifting straps is two, the lifting control mechanism can also be configured to include two take-up pulleys each having an annular channel. This can also provide a total of two annular channels for the two lifting straps. The bands correspond to the settings respectively. In addition, if the number of lifting straps is greater than two, the total number of annular channels of the lifting control mechanism can be expanded by increasing the number of take-up pulleys or opening more annular grooves on a single take-up pulley. Make it sufficient for the corresponding setting of the lifting ropes. The following will be described in detail with reference to multiple embodiments.

As shown in the figure, the lifting control mechanism 68 includes two take-up pulleys 685 and 686 in addition to the base 681, the driving wheel 682, the spring storage wheel 683, and the scroll spring 684. The two pulleys 685 and 686 are connected to each other in an interlocking manner by the gear plates below the wheel bodies meshing with each other. The take-up pulley 685 is connected to the driving wheel 682 and can drive the driving wheel 682 or be driven by the driving wheel 682 . The reel pulley The wheel body of the pulley 685 is provided with an annular channel 6851, and the pulley 686 is also provided with an annular channel 6861. The two lifting straps 5 are respectively wound on the two annular grooves 6851 and 6861 of the two winding pulleys 685 and 686 in opposite directions. When the two pulleys 685 and 686 rotate synchronously in opposite directions, the two lifting straps 5 are retracted by the two pulleys 685 and 686 at the same time, or are released by the two pulleys 685 and 686 at the same time.

請回頭參閱圖4，百葉簾100的上梁1更包含一透光調整機構11，該透光調整機構11包含一轉軸111、數量對應該等梯繩3的二個透光調整輪體112、一傳動裝置113及一操作桿114。該二透光調整輪體112固定地套設在該轉軸111上，又，該二梯繩3的上端分別對應設置在該二透光調整輪體112。更具體而言，各梯繩3的經線31、32的上端固定在所對應的透光調整輪體112上。當使用者轉動操作桿114，該傳動裝置113驅使該轉軸111轉動， 進而帶動該二透光調整輪體112旋轉，使各梯繩3的該二經線31、32其中一者朝上移動、另一者則朝下移動。隨著該二經線31、32的上下錯位，各梯繩3的該等支撐件33帶動該等葉片4在一水平位置(顯示於圖1)和一閉合位置(顯示於圖2)之間翻轉。 Please refer back to Figure 4. The upper beam 1 of the Venetian blind 100 further includes a light transmission adjustment mechanism 11. The light transmission adjustment mechanism 11 includes a rotating shaft 111, two light transmission adjustment wheel bodies 112 corresponding to the number of ladder ropes 3. A transmission device 113 and an operating lever 114. The two light-transmitting adjusting wheel bodies 112 are fixedly sleeved on the rotating shaft 111 , and the upper ends of the two ladder ropes 3 are respectively disposed corresponding to the two light-transmitting adjusting wheel bodies 112 . More specifically, the upper ends of the warps 31 and 32 of each ladder rope 3 are fixed on the corresponding light-transmitting adjusting wheel body 112 . When the user rotates the operating lever 114, the transmission device 113 drives the rotating shaft 111 to rotate. Then, the two light-transmitting adjustment wheels 112 are driven to rotate, causing one of the two warps 31 and 32 of each ladder rope 3 to move upward and the other to move downward. As the two warps 31 and 32 are displaced up and down, the supports 33 of each ladder rope 3 drive the blades 4 between a horizontal position (shown in Figure 1) and a closed position (shown in Figure 2) Flip.

值得注意的是，在本實施例中的各升降拉帶5為薄型帶狀物且其窄邊NS窄於該經線31或32的線徑，較佳地小於習知技術中用來懸吊下梁2的繩索的線徑，因此當該等葉片4被翻轉至該閉合位置，搭配各葉片4的第一穿孔41及第二穿孔42的長型開孔範圍，使得各葉片4的擺置角度較不易受到升降拉帶5的干涉，而能更為貼近該第一軸向A1，且該等葉片4中每相鄰二者之間能形成較小的間隙，藉以達成較佳的密合度而提升遮光效果。此外，各升降拉帶5穿在第一穿孔41及第二穿孔42中時，其寬邊BS大致平行於各葉片4的縱向長邊且該寬邊BS的兩側分別距離該第一穿孔41及穿孔42內緣約0.5公厘。因為各葉片4的第一穿孔41及第二穿孔42的短邊SS之寬度僅略寬於升降拉帶5的寬邊BS之寬度，又呈現規整的長方形而有別於習知的長橢圓形開孔，在各葉片4的擺置角度最貼近該第一軸向A1時，長型孔與升降拉帶5所產生的間隙十分細小，也有助於提升遮光效果。 It is worth noting that in this embodiment, each lifting strap 5 is a thin strip and its narrow side NS is narrower than the diameter of the warp 31 or 32, which is preferably smaller than that used for hanging in the conventional technology. The wire diameter of the rope of the lower beam 2, so when the blades 4 are flipped to the closed position, is matched with the elongated opening range of the first through hole 41 and the second through hole 42 of each blade 4, so that the placement of each blade 4 The angle is less susceptible to interference by the lifting strap 5 and can be closer to the first axial direction A1, and a smaller gap can be formed between each adjacent pair of blades 4 to achieve better closeness. And improve the shading effect. In addition, when each lifting strap 5 is inserted into the first through hole 41 and the second through hole 42, its wide side BS is substantially parallel to the longitudinal long side of each blade 4, and both sides of the wide side BS are respectively distanced from the first through hole 41. And the inner edge of the perforation 42 is about 0.5 mm. Because the width of the short side SS of the first through hole 41 and the second through hole 42 of each blade 4 is only slightly wider than the width of the wide side BS of the lifting strap 5, it also presents a regular rectangle, which is different from the conventional oblong shape. When the opening angle of each blade 4 is closest to the first axial direction A1, the gap between the elongated hole and the lifting strap 5 is very small, which also helps to improve the shading effect.

When each lifting strap 5 bypasses the positioning roller 731, it will be restricted by the two convex walls 7311 in the recessed portion 7312.

請同時參閱圖4、圖15及圖16。升降拉帶5從該升降控制機構6延伸至圖4中右方的轉向裝置7後，繞過第一弧形元件71的薄殼件711的外側的弧面，並沿一傳輸方向TD延伸至並繞過第二弧形元件73的定位滾輪731。此後，升降拉帶5經由底座72之出帶孔721穿出，朝該等葉片4的第二穿孔42延伸。在本實施例中，該透光調整機構11的該二透光調整輪體112分別對應設置在該二轉向裝置7的底座72之中，且各梯繩3的經線31、32的上端由該透光調整輪體112延伸出之後，分別經由該底座72底面上的該二出線孔722、723穿出。 Please also refer to Figure 4, Figure 15 and Figure 16.

在本實施例中，為了避免升降拉帶5接觸並割損梯繩3的經線31、32，該等升降拉帶5及該等梯繩3從該上梁1中穿出的位置被設計為在該方向E上互相錯開。更具體而言，各轉向裝置7的底座72的底面上所開設的出帶孔721，其位置錯開出線孔722、723，且該出帶孔721及出線孔722、723分別限制升降拉帶5及梯繩3的經線31、32穿出上梁1的位置。 In this embodiment, in order to prevent the lifting straps 5 from contacting and cutting the warps 31 and 32 of the ladder ropes 3, the positions where the lifting straps 5 and the ladder ropes 3 pass through the upper beam 1 are designed. are staggered from each other in this direction E. More specifically, the belt outlet hole 721 opened on the bottom surface of the base 72 of each steering device 7 is staggered from the cable outlet holes 722 and 723, and the belt outlet hole 721 and the cable outlet holes 722 and 723 respectively limit the lifting and pulling. The warp threads 31 and 32 of the belt 5 and the ladder rope 3 pass through the position of the upper beam 1.

請參閱圖1及圖19。該上梁1的一側邊定義一側向基準面LP。圖1中右方的梯繩3，其經線31、32從上梁1底面穿出的位置(以圓點標示)，與該側向基準面LP間隔一第一距離D1；圖1中左方的梯繩3，其經線31、32從該上梁1底面穿出的位置(以圓點標示)，與該側向基準面LP間隔一第二距離D2；圖1中右方的升降拉帶5從該上梁1底面穿出的位置(以圓點標示)，與該側向基準面LP間隔一第三距離D3；圖1中左方的升降拉帶5從該上梁1底面穿出的位置(以圓點標示)，與該側向基準面LP間隔一第四距離D4。其中，該第一距離D1、該第二距離D2、該第三距離D3及該第四距離D4皆不相同，藉此實現將各升降拉帶5及各梯繩3從該上梁1中穿出的位置配置為在該方向E上互相錯開。 Please refer to Figure 1 and Figure 19. One side of the upper beam 1 defines a lateral reference plane LP. The position where the longitudes 31 and 32 of the ladder rope 3 on the right side in Figure 1 pass out from the bottom surface of the upper beam 1 (marked by dots) are separated from the lateral reference plane LP by a first distance D1; the left side in Figure 1 The position where the longitudes 31 and 32 of the square ladder rope 3 pass through the bottom surface of the upper beam 1 (marked by dots) are separated from the lateral reference plane LP by a second distance D2; the lifting on the right side in Figure 1 The position where the strap 5 passes through the bottom surface of the upper beam 1 (marked by a dot) is separated from the lateral reference plane LP by a third distance D3; the lifting strap 5 on the left side in Figure 1 extends from the bottom surface of the upper beam 1 The penetration position (marked by a dot) is separated from the lateral reference plane LP by a fourth distance D4.

請回頭參閱圖12及圖13，在本創作第二實施例中，該透光調整機構110更包含四個固定座1121，且數量對應該等梯繩30的該四透光調整輪體1120分別對應設置在該四固定座1121之中。各梯繩30的經線310、320的上端由該透光調整輪體1120延伸出之後，分別經由開設在該固定座1121底面上的二個出線孔(圖未示)穿出，且該二出線孔在該上梁10延伸的方向E’上錯開該四轉向裝置70的底座710上開設的出帶孔716。藉此配置，亦 可避免升降拉帶50接觸並割損梯繩30的經線310、320。 Please refer back to Figures 12 and 13.

此外，當使用者將本創作的百葉簾展開到一半並停止施力，升降控制機構中的渦卷彈簧所提供的彈力，以及下梁和堆疊於其上的葉片的重量所產生的下拉力，上述二者的差值會產生一向上或向下的淨力。此時需要百葉簾機構對升降拉帶提供一定的靜摩擦阻力來對抗此淨力，方能使下梁停止在任何所需要的位置。然而，基於幅寬、材質或造型不同等因素，不同規格的百葉簾產品，其下梁和葉片的重量並不相同，所需提供的靜摩擦阻力值也不同。在此情況下，需要一種可對升降拉帶提供可調整阻力的轉向裝置，作為模組化零件同時適用在不同規格的百葉簾產品。 In addition, when the user unfolds the blinds of this invention to half and stops applying force, the elastic force provided by the scroll spring in the lifting control mechanism, as well as the downward pulling force generated by the weight of the lower beam and the blades stacked on it, The difference between the two creates a net upward or downward force. At this time, the blind mechanism needs to provide a certain static friction resistance to the lifting strap to resist this net force, so that the lower beam can stop at any required position. However, due to factors such as width, material or shape, venetian blind products of different specifications have different weights of the lower beams and blades, and the required static friction resistance values are also different. In this case, there is a need for a steering device that can provide adjustable resistance to the lifting strap, and can be used as a modular part for venetian blind products of different specifications.

請參閱圖20至圖23，其顯示本創作的百葉簾的轉向裝置的另一實施態樣，如圖所示，該轉向裝置8包含一第一弧形元件81、一底座82以及一第二弧形元件83。在本實施例中，該第一弧形元件81為一對滾筒811、812，該二滾筒811、812中各一者可繞該第一軸向A1轉動且具有一弧面。底座82的底面上開設有一出帶孔821及二個出線孔822、823貫穿該底座82的底板。同時，底座82的一側面上具有一第一安裝部824、一第二安裝部825以及一第三安裝部826位在該第一安裝部824及該第二安裝部825之間。第二弧形元件83包含一個弧形件，且該弧形件為一定位滾輪831，其結構相同於圖18所示之定位滾輪731。 Please refer to Figures 20 to 23, which show another embodiment of the turning device of the venetian blind of the present invention. As shown in the figure, the turning device 8 includes a first arc-shaped element 81, a base 82 and a second Arc element 83. In this embodiment, the first arc-shaped element 81 is a pair of rollers 811 and 812. Each of the two rollers 811 and 812 can rotate around the first axis A1 and has an arc surface. The bottom surface of the base 82 is provided with a belt outlet hole 821 and two cable outlet holes 822 and 823 penetrating the bottom plate of the base 82 . At the same time, a first mounting part 824 , a second mounting part 825 and a third mounting part 826 are provided on one side of the base 82 between the first mounting part 824 and the second mounting part 825 . The second arc-shaped component 83 includes an arc-shaped member, and the arc-shaped member is a positioning roller 831, the structure of which is the same as the positioning roller 731 shown in FIG. 18 .

值得注意的是，該定位滾輪831可選擇性地安裝在該底座82上的一第一位置P1(顯示於圖24)或一第二位置P2，藉此對升降拉帶5提供不同的阻力。其中，第一位置P1比第二位置P2更靠近第一弧形元件81。當 定位滾輪831設在第一安裝部824即位於該第一位置P1，當定位滾輪831設在第二安裝部825即位於該第二位置P2。另外，當定位滾輪831安裝在該第二位置P2，該第二弧形元件83更包含一輔助件以搭配安裝在第二位置P2的定位滾輪831使用。該輔助件可為一輔助滾輪、一金屬軸，或者與該底座82一體成形之一圓弧狀結構。 It is worth noting that the positioning roller 831 can be selectively installed at a first position P1 (shown in FIG. 24 ) or a second position P2 on the base 82 , thereby providing different resistances to the lifting strap 5 . Among them, the first position P1 is closer to the first arc-shaped element 81 than the second position P2. when When the positioning roller 831 is disposed on the first mounting part 824, it is located at the first position P1. When the positioning roller 831 is disposed on the second mounting part 825, it is located at the second position P2. In addition, when the positioning roller 831 is installed at the second position P2, the second arc-shaped component 83 further includes an auxiliary component for use with the positioning roller 831 installed at the second position P2. The auxiliary component may be an auxiliary roller, a metal shaft, or an arc-shaped structure integrally formed with the base 82 .

圖20至圖23所示之轉向裝置8的配置方式為該定位滾輪831安裝在該第二位置P2，且該第二弧形元件83更包含一輔助件。在本實施例中，該輔助件為設置在該底座82的第三安裝部826的一輔助滾輪832。升降拉帶5在延伸至此種配置的轉向裝置8並依序繞過該第一弧形元件81的該二滾筒811、812後，沿一第二預定彎折路徑T2依序繞過該定位滾輪831及該輔助滾輪832，再由出帶孔821穿出。 The steering device 8 shown in FIGS. 20 to 23 is configured such that the positioning roller 831 is installed at the second position P2, and the second arc-shaped component 83 further includes an auxiliary component. In this embodiment, the auxiliary component is an auxiliary roller 832 provided on the third mounting portion 826 of the base 82 . After the lifting belt 5 extends to the steering device 8 configured in this way and sequentially bypasses the two rollers 811 and 812 of the first arc-shaped element 81 , it then sequentially bypasses the positioning roller along a second predetermined bending path T2 831 and the auxiliary roller 832, and then pass through the belt outlet hole 821.

請參閱圖24，其顯示圖21中的轉向裝置的另一種配置方式。如圖所示，該轉向裝置8’的定位滾輪831’安裝在該第一位置P1。升降拉帶5在延伸至此種配置的轉向裝置8’並依序繞過該第一弧形元件81的該二滾筒811、812後，沿一第一預定彎折路徑T1繞過該定位滾輪831’並直接由出帶孔821穿出。在此種配置中，升降拉帶5在該轉向裝置8’中繞過較少元件且彎折較少，因此所受阻力較小。換言之，此種配置下的該轉向裝置8’，會比圖21中所示的配置的該轉向裝置8提供升降拉帶5更小的阻力。 Please refer to Figure 24, which shows another configuration of the steering device in Figure 21. As shown in the figure, the positioning roller 831' of the steering device 8' is installed at the first position P1. After the lifting belt 5 extends to the steering device 8' configured in this way and sequentially bypasses the two rollers 811 and 812 of the first arc-shaped element 81, it then bypasses the positioning roller 831 along a first predetermined bending path T1. 'And directly pass through the belt outlet hole 821. In this configuration, the lifting strap 5 passes around fewer elements and bends less in the steering device 8', so it encounters less resistance. In other words, the steering device 8' in this configuration will provide less resistance to the lifting strap 5 than the steering device 8 in the configuration shown in Figure 21.

此外，圖21中的轉向裝置亦可選擇性地在第一安裝部824及第二安裝部825上各設置一定位滾輪，並在第三安裝部826設置一輔助滾輪，使升降拉帶依序繞過該二定位滾輪及該輔助滾輪再由出帶孔821穿出。 在此種配置中，升降拉帶5繞過較多元件且彎折較多，因此所受阻力較大。換言之，此種配置下的該轉向裝置，會比圖21中所示的配置的該轉向裝置8提供升降拉帶5更大的阻力。 In addition, the steering device in Figure 21 can also optionally provide a positioning roller on each of the first mounting part 824 and the second mounting part 825, and an auxiliary roller on the third mounting part 826, so that the lifting straps can be lifted in sequence. Bypass the two positioning rollers and the auxiliary roller, and then pass through the tape outlet hole 821. In this configuration, the lifting strap 5 bypasses many components and bends more, so it experiences greater resistance. In other words, the steering device in this configuration will provide greater resistance to the lifting strap 5 than the steering device 8 in the configuration shown in FIG. 21 .
