These priors are incorporated herein by reference.
其中，如上述所提之美國專利公告號US 6,712,435中是揭露一種自閉合滑軌，並從該US 6,712,435案的圖2A、圖2B、圖3、及圖16可知，自閉合滑軌主要是於一外軌(16)的一端部位置安裝有一自動回歸機構(46)，該自動回歸機構(46)大致包含一殼體(48)、位於該殼體(48)內的一彈簧(86)、 一插銷(78)穿設在該彈簧(86)、及一槽(90)。該槽(90)包含一縱向部(92)、及一橫向部(100)橫向於該縱向部(92)所組成。其中，該槽(90)內設有一連動導引件(108)，該連動導引件(108)可於該橫向部(100)與該縱向部(92)之間位移；而一內軌(12)的端部具有一第一槽部(110)與一第二槽部(114)。該內軌(12)的端部的第一槽部(110)是對應該自動回歸機構(46)之殼體(48)的該連動導引件(108)。據此，可於該內軌(12)往一收合位置之方向位移時，該連動導引件(108)被該內軌(12)的第一槽部(110)與第二槽部(114)之導引而能藉助該彈簧(86)沿著該插銷(78)提供一彈力，以自動收合該內軌(12)而能達到滑軌之自閉合的目的。 A self-closing slide rail is disclosed in the above-mentioned U.S. Patent No. 6,712,435, and the self-closing slide rail is mainly known from Figs. 2A, 2B, 3, and 16 of the US 6,712,435 case. An automatic return mechanism (46) is mounted at one end of an outer rail (16). The automatic return mechanism (46) generally includes a housing (48), a spring (86) located in the housing (48), A latch (78) is threaded through the spring (86) and a slot (90).

圖9A與圖9B分別顯示該第二軌12相對該第一軌10處於一收合位置的狀態，以及於該收合位置的狀態下，該活動件36的第二凸部58與該減速機構16的緩衝件64的接觸部90相扺。 9A and 9B respectively show a state in which the second rail 12 is in a retracted position with respect to the first rail 10, and in a state of the retracted position, the second convex portion 58 of the movable member 36 and the speed reduction mechanism The contact portion 90 of the buffer member 64 of 16 is opposite.
詳細地說，當該第二軌12位於該收合位置，且該活動件36的至少一部分(例如，致動部60)與該擋部24卡掣時，該彈性件34提供往一第一方向D1的彈力扺於該活動件36的第一凸部56，使該活動件36的第二凸部58藉助該彈性件34的第一方向D1的彈力而扺於該接觸部90，令該接觸部90扺於該擋牆48。於此狀態之下，該減速機構16的減速彈簧66是提供往一第二方向D2的彈力作用於該緩衝件64，其中，該第二方向D2的彈力與該第一方向D1的彈力是不同的方向，例如是相反的方向。應注意的是，該彈性件34的第一方向D1的彈力是大於該減速彈簧66的第二方向D2的彈力，以確保該第二軌12相對該第一軌10收合時能保持處於該收合位置。 In detail, when the second rail 12 is in the folded position, and at least a portion of the movable member 36 (for example, the actuating portion 60) is engaged with the blocking portion 24, the elastic member 34 is provided to a first position. The elastic force of the direction D1 is applied to the first convex portion 56 of the movable member 36, so that the second convex portion 58 of the movable member 36 is biased to the contact portion 90 by the elastic force of the first direction D1 of the elastic member 34. The contact portion 90 is attached to the retaining wall 48. In this state, the deceleration spring 66 of the speed reduction mechanism 16 is configured to provide an elastic force to the buffer member 64 in a second direction D2, wherein the elastic force of the second direction D2 is different from the elastic force of the first direction D1. The direction, for example, is the opposite direction. It should be noted that the elastic force of the first direction D1 of the elastic member 34 is greater than the elastic force of the second direction D2 of the deceleration spring 66 to ensure that the second rail 12 can remain in the same position when the first rail 10 is folded. Folding position.
圖10A與圖10B顯示該第二軌12相對該第一軌10從該收合位置往該第二方向D2而朝一延伸位置活動位移的動作狀態。 10A and 10B show an operation state in which the second rail 12 is displaced relative to the first rail 10 from the folding position to the second direction D2 toward an extended position.
詳細而言，當該活動件36的致動部60卡掣在該擋部24，且該第二軌12受一外力F1(例如，被一操作者施力操作)克服該第一方向D1的彈力而往該第二方向D2的延伸位置而相對該第一軌10位移時，該活動件36的第一凸部56會扺推該彈性件34，該彈性件34回應該第一凸部56的推扺而蓄積往該第一方向D1的彈力，該第二凸部58則沿著該縱向部44活動位移，該減速彈簧66回應該第二凸部58的位移而釋放該第二方向D2的彈力的一部 分，使該緩衝件64朝向該第二方向D2位移，令該緩衝件64的接觸部90扺靠在該活動件36的第二凸部58。 In detail, when the actuating portion 60 of the movable member 36 is caught in the blocking portion 24, and the second rail 12 is subjected to an external force F1 (for example, operated by an operator), the first direction D1 is overcome. When the elastic force is displaced toward the extended position of the second direction D2 relative to the first rail 10, the first convex portion 56 of the movable member 36 pushes the elastic member 34, and the elastic member 34 corresponds to the first convex portion 56. The second elastic portion 58 is movably displaced along the longitudinal portion 44, and the deceleration spring 66 returns to the displacement of the second convex portion 58 to release the second direction D2. a part of the elasticity The buffer member 64 is displaced toward the second direction D2 such that the contact portion 90 of the cushioning member 64 abuts against the second convex portion 58 of the movable member 36.
如圖11A與圖11B所示，當該第二軌12繼續受該外力F1往該第二方向D2朝該延伸位置縱向位移時，該活動件36的第二凸部58會沿著該縱向部44活動位移並偏轉一角度卡掣在該卡掣部46之位置(一預定位置)。此時，該活動件36的致動部60自該擋部24脫離。 As shown in FIG. 11A and FIG. 11B, when the second rail 12 continues to be longitudinally displaced by the external force F1 toward the extended position in the second direction D2, the second convex portion 58 of the movable member 36 is along the longitudinal portion. The movable displacement and deflection of the angle is at the position of the click portion 46 (a predetermined position). At this time, the actuating portion 60 of the movable member 36 is detached from the blocking portion 24.
詳細而言，當該活動件36卡掣在該卡掣部46之位置時，該彈性件34又更加蓄積儲存往該第一方向D1的彈力至該活動件36的第一凸部56，使該活動件36的第二凸部58能保持卡抵於該卡掣部46的卡掣狀態。另一方面，該緩衝件64回應該減速彈簧66所繼續釋放的第二方向D2的彈力而位移，直到該緩衝件64的輔助部92於該縱向通道78活動位移並扺於該支撐部72而停止。 In detail, when the movable member 36 is locked at the position of the latching portion 46, the elastic member 34 further accumulates the elastic force stored in the first direction D1 to the first convex portion 56 of the movable member 36, so that The second convex portion 58 of the movable member 36 can maintain the stuck state of the card portion 46. On the other hand, the cushioning member 64 is displaced by the elastic force of the second direction D2 that the decelerating spring 66 continues to release until the auxiliary portion 92 of the cushioning member 64 is movably displaced in the longitudinal passage 78 and is engaged with the supporting portion 72. stop.
圖12A與圖12B顯示該第二軌12相對該第一軌10從該延伸位置往該收合位置之方向活動位移的動作狀態。 12A and 12B show an operational state of the second rail 12 relative to the first rail 10 from the extended position to the retracted position.
當該第二軌12受一外力F2(例如，被一操作者施力操作)相對該第一軌10從該延伸位置往該收合位置的方向收合的過程中，該第二軌12的導引部22是對應該活動件36的至少一部分(例如，致動部60)，此時該活動件36的第二凸部58位於該卡掣部50之位置。 When the second rail 12 is engaged by an external force F2 (for example, by an operator), the second rail 12 is folded in a direction from the extended position to the folding position. The guiding portion 22 is corresponding to at least a portion of the movable member 36 (for example, the actuating portion 60), and at this time, the second convex portion 58 of the movable member 36 is located at the position of the latching portion 50.
如圖13A與圖13B所示，當該第二軌12繼續受該外力F2而相對該第一軌10從該延伸位置往該收合位置的方向收合的過程中(例如，末段行程)，該活動件36的致動部60被該第二軌12的導引部22導引，使該致動部60被卡掣在該擋部24，以致該活動件36的第二凸部58不再與該卡掣部46相 互卡掣，該活動件36的第一凸部56受到該彈性件34所釋放往該第一方向D1的彈力，據此，該活動件36能夠回應該彈性件34的彈力，而自動地活動位移往該收合位置靠攏，使該活動件36藉助該致動部60能夠將該第二軌12帶往該收合位置之方向自動收合(如圖9B之狀態)。 As shown in FIG. 13A and FIG. 13B, when the second rail 12 continues to be engaged by the external force F2 with respect to the first rail 10 from the extended position to the folding position (for example, the last stroke) The actuating portion 60 of the movable member 36 is guided by the guiding portion 22 of the second rail 12 such that the actuating portion 60 is caught in the blocking portion 24 such that the second convex portion 58 of the movable member 36 No longer associated with the cassette 46 In the mutual engagement, the first convex portion 56 of the movable member 36 is elastically released by the elastic member 34 in the first direction D1, whereby the movable member 36 can automatically respond to the elastic force of the elastic member 34 and automatically move. The displacement is brought closer to the folding position, so that the movable member 36 can be automatically folded by the second rail 12 in the direction of the folding position by the actuating portion 60 (as shown in FIG. 9B).
於此過程中，該活動件36的第二凸部58亦推扺該緩衝件64的至少一部分(例如，該緩衝件64的接觸部90)，使該緩衝件64隨著該活動件36往該第一方向D1活動位移。其中，該彈性件34所提供之往該第一方向D1的彈力必須克服該減速彈簧66所提供且施加在該緩衝件64之往該第二方向D2的彈力(亦即，該減速彈簧66所提供的彈力相對於該彈性件34來說是為一阻力，而可用以消減該彈性件34的彈力)，才能夠使該活動件36的第二凸部58從卡掣部46之位置離開後，使該活動件36沿著該縱向部44往該第一方向D1活動位移的移動速度被減緩，從而令該活動件36自動且緩慢地將該第二軌12帶回該收合位置。 During the process, the second protrusion 58 of the movable member 36 also pushes at least a portion of the buffer member 64 (for example, the contact portion 90 of the buffer member 64), so that the buffer member 64 follows the movable member 36. The first direction D1 is displaced. The elastic force provided by the elastic member 34 in the first direction D1 must overcome the elastic force provided by the deceleration spring 66 and applied to the buffer member 64 in the second direction D2 (that is, the deceleration spring 66 The elastic force provided is a resistance with respect to the elastic member 34, and can be used to reduce the elastic force of the elastic member 34, so that the second convex portion 58 of the movable member 36 can be separated from the position of the latch portion 46. The moving speed of the movable member 36 to be displaced along the longitudinal portion 44 toward the first direction D1 is slowed, thereby causing the movable member 36 to automatically and slowly bring the second rail 12 back to the folded position.
此外，於此過程中，藉助該阻尼室76內的摩擦面80或該摩擦部84的摩擦面94，使該摩擦部84相對該阻尼室76往該第一方向D1活動位移時能夠提供另一阻力，令該活動件36的第二凸部58從該卡掣部46之位置活動位移至該縱向部44的速度能夠被減緩，以致該活動件36自動且緩慢地將該第二軌12帶回該收合位置。 In addition, in this process, by the friction surface 80 in the damper chamber 76 or the friction surface 94 of the friction portion 84, the friction portion 84 can be provided with another displacement when the damper portion 84 is displaced relative to the damper chamber 76 in the first direction D1. The resistance, the speed at which the second convex portion 58 of the movable member 36 is movably displaced from the position of the latch portion 46 to the longitudinal portion 44 can be slowed down, so that the movable member 36 automatically and slowly brings the second rail 12 Go back to the collapse position.
再者，藉助該阻尼室76內的緩衝媒介物97(此部分可配合參閱圖8B)，使該摩擦部84相對該阻尼室76往該第一方向D1活動位移時的速度能夠更有效地被減緩，並降低該緩衝件64之摩擦部84的端部直接撞擊該阻尼室76的內壁所產生的聲音，而同時具有減速與靜音的效果。 Furthermore, by means of the buffer medium 97 in the damper chamber 76 (this portion can be referred to FIG. 8B), the speed at which the friction portion 84 is displaced relative to the damper chamber 76 in the first direction D1 can be more effectively The sound generated by the end portion of the friction portion 84 of the cushioning member 64 directly hits the inner wall of the damper chamber 76 is lowered, and at the same time, the effect of deceleration and mute is obtained.
由此可知，該減速機構所提供的減速力量(例如：減速彈簧66所提供之阻力，以及摩擦面80或摩擦面94所提供之另一阻力)是小於該自閉合機構之彈性件34所提供的彈力，以令該活動件36能夠自動且緩慢地將該第二軌12帶回該收合位置，使該第二軌12相對該第一軌10被推回至鄰近該末段行程收合時，具有減速的效果。 It can be seen that the deceleration force provided by the speed reduction mechanism (for example, the resistance provided by the deceleration spring 66 and the other resistance provided by the friction surface 80 or the friction surface 94) is smaller than that provided by the elastic member 34 of the self-closing mechanism. The elastic force is such that the movable member 36 can automatically and slowly bring the second rail 12 back to the folding position, so that the second rail 12 is pushed back relative to the first rail 10 to be adjacent to the end stroke. When it has a deceleration effect.
圖14顯示本發明之具有減速機構的自閉合滑軌總成的第二實施例。 Figure 14 shows a second embodiment of the self-closing slide rail assembly of the present invention having a speed reduction mechanism.
該第二實施例與第一實施例之差異大致上在於：該基座200包含一第一縱向段202、及一支撐部204自該第一縱向段202橫向地延伸(亦即，該基座200未包含第一實施例的第二縱向段70)。據此，藉助該減速彈簧206、該第一縱向段202之摩擦面208與緩衝件210的摩擦面(未繪示)、及阻尼室內212的緩衝媒介物，同樣可達到令該活動件214自動且緩慢地將第二軌往第一方向D1帶回收合位置。其中，為了簡明起見，關於減速彈簧206、摩擦面、及緩衝媒介物請參考第一實施例即可，於此不另贅述。 The difference between the second embodiment and the first embodiment is that the base 200 includes a first longitudinal section 202 and a support portion 204 extends laterally from the first longitudinal section 202 (ie, the base 200 does not include the second longitudinal section 70) of the first embodiment. Accordingly, the movable member 214 can be automatically realized by the friction spring 206, the friction surface 208 of the first longitudinal section 202 and the friction surface of the buffer member 210 (not shown), and the buffering medium of the damping chamber 212. And slowly returning the second rail to the first direction D1 with the recovery position. For the sake of brevity, please refer to the first embodiment for the deceleration spring 206, the friction surface, and the buffer medium, and no further details are provided herein.
圖15顯示本發明之具有減速機構的自閉合滑軌總成的第三實施例。 Figure 15 shows a third embodiment of the self-closing slide rail assembly of the present invention having a speed reduction mechanism.
該第三實施例與第一實施例之差異大致上在於：該第一軌300更包含一側牆302，該側牆302具有一連接段304，該減速彈簧306縱向地連接在該連接段304與該緩衝件308(例如，該緩衝件308的一前部309)之間。 The difference between the third embodiment and the first embodiment is that the first rail 300 further includes a side wall 302 having a connecting portion 304, and the deceleration spring 306 is longitudinally connected to the connecting portion 304. Between the bumper 308 (eg, a front portion 309 of the bumper 308).
如圖15、圖16所示，當該自閉合機構310的活動件312被卡掣在該卡掣部314之位置時，由於該減速彈簧306提供往第二方向D2的彈力至該緩衝件308，使該緩衝件308亦停留在一位置(如圖16)，於此狀態下，當第 二軌(未繪示)相對該第一軌300往第一方向D1朝一收合位置收合的過程中，該活動件312的致動部316能夠卡掣在該第二軌(例如，該擋部24，此部分可參考圖13A)，使該活動件312離開該卡掣部314的位置，據此該彈性件318能夠釋放往該第一方向D1的彈力，使該活動件312離開該卡掣部314之位置後，令該活動件312能夠回應該彈性件318所釋放的彈力而沿著該縱向部320往該第一方向D1活動位移，從而令該活動件312自動且緩慢地將第二軌帶回收合位置。 As shown in FIG. 15 and FIG. 16, when the movable member 312 of the self-closing mechanism 310 is clamped at the position of the latching portion 314, the spring force from the decelerating spring 306 to the second direction D2 to the buffer member 308 is provided. So that the buffer member 308 also stays in a position (as shown in FIG. 16), in this state, when the first During the process of folding the two rails (not shown) relative to the first rail 300 in the first direction D1 toward a folding position, the actuating portion 316 of the movable member 312 can be clamped on the second rail (for example, the block) The portion 24, which can be referred to FIG. 13A), causes the movable member 312 to leave the position of the latch portion 314, whereby the elastic member 318 can release the elastic force to the first direction D1, so that the movable member 312 leaves the card. After the position of the crotch portion 314, the movable member 312 can be moved to the first direction D1 along the longitudinal portion 320 in response to the elastic force released by the elastic member 318, so that the movable member 312 automatically and slowly The two rails are recycled.
於此過程中，由於該減速彈簧306提供往該第二方向D2之彈力至該緩衝件308，當該活動件312藉助彈性件318所提供且往該第一方向D1的彈力推扺該緩衝件308的接觸部322時，該減速彈簧306所提供的彈力相對於該彈性件318的彈力來說是為一阻力，而同樣可達到令該活動件312自動且緩慢地將該第二軌帶回該收合位置。 In this process, since the deceleration spring 306 provides the elastic force to the buffer member 308 in the second direction D2, when the movable member 312 is provided by the elastic member 318 and the elastic force in the first direction D1 is pushed, the buffer is pushed. When the contact portion 322 of the member 308 is used, the elastic force provided by the deceleration spring 306 is a resistance with respect to the elastic force of the elastic member 318, and the movable member 312 can also be automatically and slowly brought to the second rail. Go back to the collapse position.
此外，由於阻尼室內之摩擦面與摩擦部之摩擦面、以及填充於阻尼室內之緩衝媒介物的關係，使該第二軌相對該第一軌300被推回至該末段行程而收合時更具有減速的效果。由於此部分已揭露於第一實施例(如圖13B及圖8A與8B)，為了簡明起見，於此不另贅述。 In addition, due to the relationship between the friction surface of the damping chamber and the friction surface of the friction portion and the buffer medium filled in the damping chamber, the second rail is pushed back to the end stroke and folded when the first rail 300 is pushed back relative to the first rail 300. It has a slower effect. Since this part has been disclosed in the first embodiment (as shown in FIG. 13B and FIGS. 8A and 8B), for the sake of brevity, no further details are provided herein.
圖17顯示本發明之第四實施例。 Figure 17 shows a fourth embodiment of the present invention.
該第四實施例與第一實施例之差異大致上在於：該減速機構的基座402具有一摩擦部404，該摩擦部404具有一摩擦面406、及一凸肋408位置相對該摩擦面406，該緩衝件410活動地連接該摩擦部404，該緩衝件410至少包含一第一牆412a、一第二牆412b、及一底牆412c延伸連接在該第一牆412a與該第二牆412b之間，該第一牆412a、該第二牆412b、及該底牆412c 定義出一阻尼室414對應該摩擦部404。 The difference between the fourth embodiment and the first embodiment is that the base 402 of the speed reduction mechanism has a friction portion 404 having a friction surface 406 and a rib 408 positioned opposite the friction surface 406. The buffering member 410 is movably connected to the friction portion 404. The buffering member 410 includes at least a first wall 412a, a second wall 412b, and a bottom wall 412c extending from the first wall 412a and the second wall 412b. The first wall 412a, the second wall 412b, and the bottom wall 412c A damper chamber 414 is defined to correspond to the friction portion 404.
該緩衝件410的第一牆412a包含一摩擦面416位於該阻尼室414內，該摩擦面416對應該摩擦部404的摩擦面406(例如，摩擦面416、406為相互對應之鋸齒狀)；該緩衝件410的第二牆412b包含一凹溝418對應該摩擦部404的凸肋408。此外，該阻尼室410亦可被填充有緩衝媒介物(此部分的原理可參考圖8B即可，於此不另贅述)。 The first wall 412a of the buffer member 410 includes a friction surface 416 located in the damping chamber 414, and the friction surface 416 corresponds to the friction surface 406 of the friction portion 404 (for example, the friction surfaces 416, 406 are in a zigzag shape corresponding to each other); The second wall 412b of the buffer member 410 includes a rib 408 corresponding to the groove 418 corresponding to the friction portion 404. In addition, the damper chamber 410 can also be filled with a buffering medium (the principle of this part can be referred to FIG. 8B, which will not be further described herein).
該減速機構的基座402更包含一牆部420，該減速彈簧422縱向地連接在該牆部420與該緩衝件410(例如，該緩衝件410的一後部423)之間。 The base 402 of the speed reduction mechanism further includes a wall portion 420 that is longitudinally coupled between the wall portion 420 and the cushioning member 410 (eg, a rear portion 423 of the cushioning member 410).
如圖17、圖18所示，當該活動件424被卡掣在該卡掣部426的位置時，由於該減速彈簧422提供往第二方向D2的彈力至該緩衝件410，使該緩衝件410亦停留在一位置，於此狀態下，當第二軌(未繪示)相對該第一軌428往第一方向D1的一收合位置收合的過程中，該活動件424的致動部430卡掣在該第二軌(例如，該擋部24，此部分可參考圖13A)，使該活動件424能夠離開該卡掣部426的位置，據此該彈性件432提供往該第一方向D1的彈力，使該活動件424離開該卡掣部426之位置後，令該活動件424能夠回應該彈性件432所提供的彈力而沿著該縱向部434往該第一方向D1活動位移，從而令該活動件424自動且緩慢地將第二軌帶回收合位置。 As shown in FIG. 17 and FIG. 18, when the movable member 424 is clamped at the position of the latching portion 426, the buffer member is provided by the decelerating spring 422 to the spring member 410 in the second direction D2. The 410 also stays in a position. In this state, when the second rail (not shown) is folded relative to the first rail 428 in a first position D1, the movable member 424 is actuated. The portion 430 is clamped on the second rail (for example, the blocking portion 24, this portion can be referred to FIG. 13A), so that the movable member 424 can be separated from the position of the latch portion 426, whereby the elastic member 432 is provided to the first portion. The elastic force of the direction D1 causes the movable member 424 to leave the position of the latching portion 426, so that the movable member 424 can respond to the elastic force provided by the elastic member 432 and move along the longitudinal portion 434 to the first direction D1. Displacement, thereby causing the movable member 424 to automatically and slowly retract the second rail.
於此過程中，由於該減速彈簧422提供往該第二方向D2之彈力至該緩衝件410，當該活動件424藉助彈性件432所提供且往該第一方向D1的彈力推扺該緩衝件410的接觸部436時，該減速彈簧422所提供的彈力相對於該彈性件432的彈力來說是為一阻力，同樣可達到令該活動件424自動且 緩慢地將該第二軌帶回該收合位置。 In this process, since the deceleration spring 422 provides the elastic force to the buffer member 410 in the second direction D2, when the movable member 424 is provided by the elastic member 432 and the elastic force in the first direction D1 is pushed, the buffer is pushed. When the contact portion 436 of the member 410 is 436, the elastic force provided by the speed reducing spring 422 is a resistance with respect to the elastic force of the elastic member 432, and the movable member 424 can also be automatically and Slowly bring the second rail back to the collapsed position.
此外，藉助該阻尼室414內之摩擦面416與摩擦部404之摩擦面406，使該活動件424帶動該緩衝件410時，該緩衝件410相對該摩擦部404提供一阻力。以及，藉助填充於該阻尼室414內之緩衝媒介物，使該第二軌相對該第一軌428被推回至該末段行程而收合時更具有減速的效果。 In addition, the cushioning member 410 provides a resistance to the friction portion 404 when the movable member 424 drives the cushioning member 410 by the friction surface 416 of the damping chamber 414 and the friction surface 406 of the friction portion 404. And, by the buffer medium filled in the damper chamber 414, the second rail is pushed back to the last stroke relative to the first rail 428 to have a deceleration effect when folded.
