Description

滑轨总成Slide rail assembly

技术领域technical field

本发明涉及一种滑轨总成,特别是指一种一第一轨与一第二轨可相对彼此在一延伸位置具有阻挡机制,且通过一操作件可解除所述阻挡机制的滑轨总成。The present invention relates to a slide rail assembly, in particular to a slide rail assembly in which a first rail and a second rail can have a blocking mechanism in an extended position relative to each other, and the blocking mechanism can be released by an operating member to make.

背景技术Background technique

如美国专利公告号US 10,041,535 B2揭露一种滑轨总成,其包含一第一轨、一第二轨、一第三轨、一锁定件及一操作件。该第二轨可相对该第一轨从一第一位置活动至一第二位置;该第三轨可相对该第二轨活动;该锁定件安装在该第二轨,用以在该第二轨处于该第二位置时,该锁定件能够锁定该第一轨的一部位,使该第二轨无法相对该第一轨从该第二位置往该第一位置活动;使用者可施加一力量至该操作件,使该操作件相对该第二轨从一第一预定位置位移至一第二预定位置,用以解除该锁定件对该第一轨的该部位的锁定。该操作件被使用者施加该力量从该第一预定位置位移至该第二预定位置时,虽可用以解除该锁定件对该第一轨的该部位的锁定,但是该第三轨自该第二轨的卸下动作需仰赖该第二轨推入该第一轨的位移来相互配合,这种操作方式显然不利单人操作,甚至需搭配台车使用,才能将配置有第三轨的机箱(chassis)在狭隘空间的环境下自该第二轨上卸下。For example, US Patent Publication No. US 10,041,535 B2 discloses a slide rail assembly, which includes a first rail, a second rail, a third rail, a locking member and an operating member. The second rail is movable relative to the first rail from a first position to a second position; the third rail is movable relative to the second rail; When the rail is in the second position, the locking member can lock a part of the first rail, so that the second rail cannot move relative to the first rail from the second position to the first position; the user can apply a force To the operating member, the operating member is displaced relative to the second rail from a first predetermined position to a second predetermined position, so as to release the locking member from the portion of the first rail. When the operating member is displaced from the first predetermined position to the second predetermined position by the force exerted by the user, although the operating member can be used to release the locking of the portion of the first rail by the locking member, the third rail is removed from the first rail. The unloading action of the second rail needs to rely on the displacement of the second rail pushed into the first rail to cooperate with each other. This operation method is obviously unfavorable for single-person operation, and even needs to be used with a trolley to remove the chassis equipped with the third rail. (chassis) unloading from the second rail in a confined space environment.

如美国专利公告号US 9,681,749 B2揭露一种亦可应用在狭隘空间的滑轨总成,该案揭示操作件通过一复归弹性件可从一预定位置回到一初始位置,这也意味着,一旦使用者停止施加该力量至该操作件,该操作件就会响应该复归弹性件的弹力而被强制地从该预定位置带回该初始位置。然而,若机箱单侧安装有二组滑轨时,则该机箱两侧会有四只滑轨,因此,更不利于单人的双手操作,显见这种通过复归弹性件的弹力将操作件从该预定位置强制带回该初始位置的机制并未能满足市场上特定的需求。For example, US Patent Publication No. US 9,681,749 B2 discloses a slide rail assembly that can also be used in narrow spaces. The case discloses that the operating member can be returned from a predetermined position to an initial position through a return elastic member, which also means that once When the user stops applying the force to the operating member, the operating member is forcibly brought back to the initial position from the predetermined position in response to the elastic force of the return elastic member. However, if two sets of slide rails are installed on one side of the chassis, there will be four slide rails on both sides of the chassis, so it is even more unfavorable for a single person to operate with both hands. The mechanism for forcing the predetermined position back to the initial position does not meet the specific needs of the market.

如图11所示,当该第二轨24相对该第一轨22从上述第一延伸位置E1往该收合方向D2位移的过程中,该操作件60的该弹性构件90的解掣特征98(的第二导引特征100b)与该第一轨22的第一释放特征34(的第一导引段44a)产生接触作用,可带动该弹性构件90的弹性段94,用以将该卡掣特征88从该第二轨24的该预定墙112的第二墙部112b解掣。As shown in FIG. 11 , when the second rail 24 is displaced relative to the first rail 22 from the first extending position E1 to the retracting direction D2 , the unlocking feature 98 of the elastic member 90 of the operating member 60 (The second guide feature 100b of the) comes into contact with the first release feature 34 of the first rail 22 (the first guide section 44a of the first rail 22), and can drive the elastic section 94 of the elastic member 90 to drive the card The detent feature 88 is disengaged from the second wall portion 112b of the predetermined wall 112 of the second rail 24 .

如图12与图13所示,该第二轨24可相对该第一轨22继续往该收合方向D2位移。其中,一旦该卡掣特征88不再卡掣于该第二轨24的该预定墙112的第二墙部112b,通过该复归弹性件64释放该复归弹力F’至该操作件60,使该操作件60能从上述第二操作位置P2回到该第一操作位置P1,以致该卡掣特征88回到相邻于该第二轨24的该预定墙112的第一墙部112a的位置(如图13所示,此部分亦可配合参阅图5),且该挡件58与该定位件62分别响应该第一弹性特征70与该第二弹性特征72释放弹力而从上述第二状态S2回到该第一状态S1。As shown in FIG. 12 and FIG. 13 , the second rail 24 can continue to displace relative to the first rail 22 in the retracting direction D2 . Wherein, once the latching feature 88 is no longer latched on the second wall portion 112b of the predetermined wall 112 of the second rail 24, the return elastic force F' is released to the operating member 60 through the return elastic member 64, so that the The operating member 60 can return to the first operating position P1 from the second operating position P2, so that the latching feature 88 returns to the position of the first wall portion 112a of the predetermined wall 112 adjacent to the second rail 24 ( As shown in FIG. 13 , this part can also be referred to in FIG. 5 ), and the blocking member 58 and the positioning member 62 respectively respond to the release of the elastic force of the first elastic feature 70 and the second elastic feature 72 from the above-mentioned second state S2 Return to the first state S1.

如图14与图15所示,当该第二轨24相对该第一轨22进一步往该收合方向D2位移至一第二延伸位置E2的过程中,该定位件62通过该定位部63沿着该第一辅助部46的第一导引结构50(斜面或弧面)的导引而枢转一角度,以致该第二弹性特征72处于累积弹力的状态(如图14所示),直到该第二轨24处于该第二延伸位置E2时(配合图16所示),该定位件62响应该第二弹性特征72释放弹力处于该第一状态S1,令该定位件62的定位部63能卡掣于该第一轨22的定位特征36,例如使该定位件62的定位部63被阻挡在该第一辅助部46与该第二辅助部48之间,用以防止该第二轨24相对该第一轨22从该第二延伸位置E2往该收合方向D2或该开启方向D1位移。As shown in FIG. 14 and FIG. 15 , when the second rail 24 is further displaced relative to the first rail 22 in the retracting direction D2 to a second extending position E2 , the positioning member 62 passes through the positioning portion 63 along the The second elastic feature 72 is in a state of accumulating elastic force (as shown in FIG. 14 ) until the second elastic feature 72 is in a state of accumulating elastic force (as shown in FIG. 14 ). When the second rail 24 is in the second extending position E2 (as shown in FIG. 16 ), the positioning member 62 is in the first state S1 in response to the release of the elastic force of the second elastic feature 72 , so that the positioning portion 63 of the positioning member 62 is in the first state S1 . The positioning feature 36 of the first rail 22 can be caught, for example, the positioning portion 63 of the positioning member 62 is blocked between the first auxiliary portion 46 and the second auxiliary portion 48 to prevent the second rail 24 is displaced relative to the first rail 22 from the second extending position E2 to the retracting direction D2 or the opening direction D1.

如图16与图17所示,当该第二轨24相对该第一轨22处于该第二延伸位置E2时,该滑轨总成20具有一第二长度J2小于上述第一长度J1,以致该第三轨26的前端部26a与该物体122之间具有一第二距离X2更大于上述第一距离X1,因此,有利于该第三轨26往该开启方向D1自该第二轨24的第二通道卸下(如图17所示)。As shown in FIGS. 16 and 17 , when the second rail 24 is in the second extended position E2 relative to the first rail 22 , the slide rail assembly 20 has a second length J2 smaller than the first length J1 , so that A second distance X2 between the front end portion 26a of the third rail 26 and the object 122 is greater than the above-mentioned first distance X1. Therefore, it is beneficial for the third rail 26 to move from the second rail 24 in the opening direction D1. The second channel is removed (as shown in Figure 17).

如图18至图20所示,该第三轨26包含一第一墙29a、一第二墙29b与一纵向墙31连接在该第三轨26的第一墙29a与第二墙29b之间。进一步而言,若欲使该第二轨24相对该第一轨22从该第二延伸位置E2往该收合方向D2位移至一收合位置R(例如完全收合位置),可将该第三轨26从上述开启位置K往该收合方向D2位移,直到该第三轨26(例如后端部26b)接触该挡件58的一辅助段124(该辅助段124连接该挡件58的致动部104,如图18所示),使该挡件58不再处于该第一状态S1,且该挡件58能够连动该定位件62也不再处于该第一状态S1,使该定位件62的定位部63从该定位特征36解掣(如图19所示),用以允许该第二轨24相对该第一轨22从该第二延伸位置E2往该收合方向D2位移,直到该滑轨总成20处于一完全收合状态(如图20所示),此时,该第二轨24相对该第一轨22处于该收合位置R,且该第三轨26也相对该第二轨24处于一预定收合位置。值得一提的是,如图19与图20所示,通过该第三轨26的第二墙29b与第一墙29a分别支撑该挡件58与该定位件62,用以将该挡件58与该定位件62保持在非该第一状态S1(亦即,该挡件58与该定位件62不是处于该第一状态S1),且该第一弹性特征70与该第二弹性特征72处于累积弹力的状态,值得一提的是,由于该第三轨26的第一墙29a阻挡在该定位件62的活动路径(枢转路径),该定位件62可保持在非该第一状态S1。As shown in FIGS. 18 to 20 , the third rail 26 includes a first wall 29 a , a second wall 29 b and a longitudinal wall 31 connected between the first wall 29 a and the second wall 29 b of the third rail 26 . Further, if the second rail 24 is to be displaced relative to the first rail 22 from the second extending position E2 to the retracting direction D2 to a retracting position R (for example, a fully retracting position), the first rail 24 can be The three rails 26 are displaced from the above-mentioned opening position K to the retracting direction D2 until the third rail 26 (eg, the rear end 26 b ) contacts an auxiliary section 124 of the blocking member 58 (the auxiliary section 124 is connected to the blocking member 58 ). Actuating portion 104, as shown in FIG. 18), so that the blocking member 58 is no longer in the first state S1, and the blocking member 58 can be linked to the positioning member 62 and is no longer in the first state S1, so that the blocking member 58 is no longer in the first state S1. The positioning portion 63 of the positioning member 62 is released from the positioning feature 36 (as shown in FIG. 19 ) to allow the second rail 24 to move relative to the first rail 22 from the second extending position E2 to the retracting direction D2 , until the slide rail assembly 20 is in a fully retracted state (as shown in FIG. 20 ). At this time, the second rail 24 is in the retracted position R relative to the first rail 22 , and the third rail 26 is also in the retracted position R. The second rail 24 is in a predetermined retracted position. It is worth mentioning that, as shown in FIGS. 19 and 20 , the blocking member 58 and the positioning member 62 are respectively supported by the second wall 29b and the first wall 29a of the third rail 26 for the blocking member 58 and the positioning member 62 remain in the non-first state S1 (that is, the blocking member 58 and the positioning member 62 are not in the first state S1 ), and the first elastic feature 70 and the second elastic feature 72 are in In the state of accumulating elastic force, it is worth mentioning that since the first wall 29a of the third rail 26 blocks the moving path (pivoting path) of the positioning member 62, the positioning member 62 can remain in the non-first state S1 .

如图20至图23所示,该第三轨26包含一同步特征126(例如孔壁,但实施上不局限)设置在该第三轨26的第二墙29b。进一步而言,当该第三轨26相对该第二轨24从收合位置(如图20所示)往该开启方向D1位移至一预定行程时,该第三轨26的同步特征126对应至该挡件58的辅助段124,使该挡件58响应该第一弹性特征70释放弹力能通过该辅助段124卡掣于该第三轨26的同步特征126,用以让该第二轨24能与该第三轨26同步地往该开启方向D1位移(如图21所示),于同步地往该开启方向D1位移至一预定行程时,该挡件58的挡部55会沿着该第一轨22的弹性座33的导引部27,且到达该弹性座33的纵向部25,使该挡件58偏转一角度,以致该挡件58的辅助段124自该第三轨26的同步特征126解掣,用以解除该第二轨24与该第三轨26的同步位移关系((如图22所示),直到该第三轨26相对该第二轨24往该开启方向D1位移,使该第三轨26的第二墙29b与第一墙29a分别不再支撑该挡件58与该定位件62,且该第二轨24相对该第一轨22位移至该第一延伸位置E1时,该挡件58处于该第一状态S1,且该挡件58的挡部55被该第一轨22的阻挡特征32阻挡,用以防止该第二轨24从该第一延伸位置E1往该收合方向D2位移(如图23所示,此部分亦可配合参阅图9)。As shown in FIGS. 20-23 , the third rail 26 includes a synchronizing feature 126 (eg, a hole wall, but the implementation is not limited) disposed on the second wall 29 b of the third rail 26 . Further, when the third rail 26 is displaced relative to the second rail 24 from the retracted position (as shown in FIG. 20 ) to the opening direction D1 to a predetermined stroke, the synchronization feature 126 of the third rail 26 corresponds to The auxiliary section 124 of the blocking member 58 enables the blocking member 58 to be latched on the synchronizing feature 126 of the third rail 26 through the auxiliary section 124 in response to the release of the elastic force of the first elastic feature 70 , so as to allow the second rail 24 It can move to the opening direction D1 synchronously with the third rail 26 (as shown in FIG. 21 ). When the third rail 26 moves to the opening direction D1 to a predetermined stroke synchronously, the blocking portion 55 of the blocking member 58 will move along the opening direction D1. The guide portion 27 of the elastic seat 33 of the first rail 22 and reaching the longitudinal portion 25 of the elastic seat 33 deflects the stopper 58 by an angle, so that the auxiliary section 124 of the stopper 58 moves away from the third rail 26 . The synchronizing feature 126 is released to release the synchronous displacement relationship between the second rail 24 and the third rail 26 (as shown in FIG. 22 ), until the third rail 26 moves toward the opening direction D1 relative to the second rail 24 The displacement causes the second wall 29b and the first wall 29a of the third rail 26 to no longer support the blocking member 58 and the positioning member 62, respectively, and the second rail 24 is displaced relative to the first rail 22 to the first extension At the position E1, the blocking member 58 is in the first state S1, and the blocking portion 55 of the blocking member 58 is blocked by the blocking feature 32 of the first rail 22 to prevent the second rail 24 from the first extended position E1 is displaced toward the retracting direction D2 (as shown in FIG. 23 , this part can also be referred to in FIG. 9 ).

如图24与图25所示,当该第二轨24相对该第一轨22处于该第二延伸位置E2时,除了可通过上述该第三轨26解除该第二轨24与该第一轨22的卡掣关系之外(例如图18与图19),在此实施型态中,使用者亦可直接通过操作件60来解除该第二轨24与该第一轨22的卡掣关系。进一步而言,当该第二轨24相对该第一轨22处于该第二延伸位置E2时,用户可施加该力量F至该操作件60从该第一操作位置P1活动至该第二操作位置P2,且通过驱动部80能带动该挡件58从该第一状态S1转换成该第二状态S2,使该挡件58带动该定位件62从该第一状态S1转换成该第二状态S2,使该定位件62的定位部63从该第一轨22的定位特征36解掣,用以允许该第二轨24相对该第一轨22从该第二延伸位置E2往该收合方向D2(或该开启方向D1)位移。其中,当该操作件60处于该第二操作位置P2时,该操作件60通过该卡掣特征88卡掣于该第二轨24的上述预定部,用以将该操作件60保持在该第二操作位置P2(此部分亦可配合参阅图7)。As shown in FIGS. 24 and 25 , when the second rail 24 is at the second extended position E2 relative to the first rail 22 , the third rail 26 can be used to release the second rail 24 from the first rail. In addition to the latching relationship of the second rail 22 (eg, FIG. 18 and FIG. 19 ), in this embodiment, the user can also directly release the latching relationship between the second rail 24 and the first rail 22 through the operating member 60 . Further, when the second rail 24 is in the second extending position E2 relative to the first rail 22, the user can apply the force F to the operating member 60 to move from the first operating position P1 to the second operating position P2, and the driving part 80 can drive the blocking member 58 to convert from the first state S1 to the second state S2, so that the blocking member 58 drives the positioning member 62 to convert from the first state S1 to the second state S2 , the positioning portion 63 of the positioning member 62 is released from the positioning feature 36 of the first rail 22 to allow the second rail 24 to move from the second extending position E2 to the retracting direction D2 relative to the first rail 22 (or the opening direction D1) displacement. Wherein, when the operating member 60 is in the second operating position P2, the operating member 60 is locked on the predetermined portion of the second rail 24 through the locking feature 88, so as to keep the operating member 60 in the first position Two operating positions P2 (this part can also be seen in Figure 7).

当该第二轨24从该第二延伸位置E2往该收合方向D2位移至收合位置R的过程中,通过该第一轨22的第二释放特征38可带动该弹性构件90,用以将该卡掣特征88从该第二轨24的该预定部解掣,使该操作件60通过复归弹性件64的复归弹力F’能从该第二操作位置P2回到该第一操作位置P1(由在此部分的技术原理与图11实质上相同,在此不另赘述)。When the second rail 24 is displaced from the second extending position E2 to the retracting direction D2 to the retracting position R, the elastic member 90 can be driven by the second releasing feature 38 of the first rail 22 to drive the elastic member 90 . The locking feature 88 is released from the predetermined portion of the second rail 24 , so that the operating member 60 can return to the first operating position P1 from the second operating position P2 by the restoring elastic force F′ of the restoring elastic member 64 (Because the technical principle of this part is substantially the same as that of FIG. 11 , it will not be repeated here).

本发明第一实施例的滑轨总成20包含的特点:可通过卡掣特征88卡掣于该第二轨24的该预定部而将该操作件60保持在该第二操作位置P2,一旦该卡掣特征88不再卡掣于该第二轨24的该预定部,通过该复归弹性件64提供复归弹力可让该操作件60从该第二操作位置P2回到该第一操作位置P1。The sliding rail assembly 20 according to the first embodiment of the present invention includes the feature that the operating member 60 can be held in the second operating position P2 by the latching feature 88 being latched on the predetermined portion of the second rail 24.

图30与图31为本发明第三实施例的滑轨总成300。此第三实施例的滑轨总成300与上述第一实施例的滑轨总成20的差异实质上在于:省略了上述的复归弹性件64、弹性构件90以及第二轨24的预定墙112。30 and 31 are slide rail assemblies 300 according to the third embodiment of the present invention. The difference between the slide rail assembly 300 of the third embodiment and the slide rail assembly 20 of the first embodiment is that the above-mentioned return elastic member 64 , the elastic member 90 and the predetermined wall 112 of the second rail 24 are omitted. .

具体而言,此第三实施例的第一轨302具有一第一辅助特征304,操作件305设置一第二辅助特征306用以与第一辅助特征304搭配使用,在此,以该第一辅助特征304与该第二辅助特征306皆为凸出物,但实施上不局限。此外,该操作件305具有卡掣特征308,且第二轨310设置有至少一预定部,例如一第一预定部312与一第二预定部314,用以分别与该卡掣特征308相互卡掣,使该操作件305相对该第二轨310处于第一操作位置P1(如图30所示)或第二操作位置P2(如图31所示)时能够保持在该第一操作位置P1或该第二操作位置P2。在此实施例中,该卡掣特征308为一连接件(螺钉或销)穿过第二轨310的一长孔315的至少一部分,且该第一预定部312与第二预定部314位于该长孔315内;较佳地,该卡掣特征308、该第一预定部312及/或第二预定部314包含导引面(例如斜面或弧面),使该操作件305可易于离开该第一操作位置P1或该第二操作位置P2。Specifically, the first rail 302 of the third embodiment has a first auxiliary feature 304, and the operating member 305 is provided with a second auxiliary feature 306 for use with the first auxiliary feature 304. Here, the first auxiliary feature 304 is used. Both the auxiliary feature 304 and the second auxiliary feature 306 are protrusions, but the implementation is not limited. In addition, the operating member 305 has a latching feature 308, and the second rail 310 is provided with at least one predetermined portion, such as a first predetermined portion 312 and a second predetermined portion 314, for engaging with the latching feature 308 respectively. When the operating member 305 is in the first operating position P1 (as shown in FIG. 30 ) or the second operating position P2 (as shown in FIG. 31 ) relative to the second rail 310 , the operating member 305 can be maintained in the first operating position P1 or The second operating position P2. In this embodiment, the latching feature 308 is at least a part of an elongated hole 315 of a connecting member (screw or pin) passing through the second rail 310 , and the first predetermined portion 312 and the second predetermined portion 314 are located in the Preferably, the latching feature 308, the first predetermined portion 312 and/or the second predetermined portion 314 include a guide surface (such as an inclined surface or an arc surface), so that the operating member 305 can easily leave the The first operating position P1 or the second operating position P2.

进一步而言,该滑轨总成300可处于该完全延伸状态。其中,该第二轨310相对该第一轨302处于该第一延伸位置E1,且第三轨316相对该第二轨310处于该开启位置K。当该第二轨310处于该第一延伸位置E1时,该滑轨总成300具有第一长度。其中,当该第二轨310相对该第一轨302处于该第一延伸位置E1时,阻挡特征318能阻挡处于该第一状态S1的挡件320的挡部322,用以防止该第二轨310从该第一延伸位置E1往收合方向D2位移(如图30所示)。另一方面,定位件324通过定位部326接触在该第一轨302的弹性座328的导引部330。Further, the slide rail assembly 300 may be in the fully extended state. Wherein, the second rail 310 is in the first extending position E1 relative to the first rail 302 , and the third rail 316 is in the open position K relative to the second rail 310 . When the second rail 310 is in the first extended position E1, the slide rail assembly 300 has a first length. Wherein, when the second rail 310 is in the first extended position E1 relative to the first rail 302, the blocking feature 318 can block the blocking portion 322 of the blocking member 320 in the first state S1, so as to prevent the second rail 310 is displaced from the first extending position E1 to the retracting direction D2 (as shown in FIG. 30 ). On the other hand, the positioning member 324 contacts the guiding portion 330 of the elastic seat 328 of the first rail 302 through the positioning portion 326 .

使用者可通过施加力量F至该操作件305,使该操作件305从第一操作位置P1(如图30所示)活动至第二操作位置P2(如图31所示),且通过操作件305的驱动部332能带动该挡件320从第一状态S1转换(例如枢转)成该第二状态S2且将该挡件320保持在该第二状态S2,使该阻挡特征318不能阻挡处于该第二状态S2的该挡件320的挡部322,用以允许该第二轨310相对该第一轨302能从该第一延伸位置E1往该收合方向D2位移(如图31所示)。另一方面,该挡件320连动该定位件324(例如连动该定位件324枢转),使该定位件324也处于该第二状态S2。当该挡件320与该定位件324处于该第二状态S2时,第一弹性特征334与第二弹性特征336分别处于累积弹力的状态(如图31所示)。The user can move the operating member 305 from the first operating position P1 (shown in FIG. 30 ) to the second operating position P2 (shown in FIG. 31 ) by applying a force F to the operating member 305 , and the operating member 305 can be moved by the operating member The driving portion 332 of the 305 can drive the blocking member 320 to convert (eg pivot) from the first state S1 to the second state S2 and keep the blocking member 320 in the second state S2, so that the blocking feature 318 cannot block the blocking member 318 in the second state S2. The blocking portion 322 of the blocking member 320 in the second state S2 is used to allow the second rail 310 to be displaced relative to the first rail 302 from the first extending position E1 to the retracting direction D2 (as shown in FIG. 31 ) ). On the other hand, the blocking member 320 is linked with the positioning member 324 (eg, linked with the positioning member 324 to pivot), so that the positioning member 324 is also in the second state S2. When the blocking member 320 and the positioning member 324 are in the second state S2, the first elastic feature 334 and the second elastic feature 336 are respectively in a state of accumulating elastic force (as shown in FIG. 31 ).

如图31与图32所示,当该第二轨310相对该第一轨302从第一延伸位置E1往该收合方向D2位移的过程中,处于该第二状态S2的该挡件320的挡部322,以及处于该第二状态S2的定位件324通过定位部326未能对应该第一轨302的定位特征338,因此,该挡件320与该定位件324可以直接往该收合方向D2越过该第一轨302的定位特征338(如图32所示),且当该第二轨310相对该第一轨302往该收合方向D2位移至一预定行程时,该操作件305的第二辅助特征306会接触第一轨302的第一辅助特征304(如图32所示)。As shown in FIG. 31 and FIG. 32 , when the second rail 310 is displaced relative to the first rail 302 from the first extending position E1 to the retracting direction D2, the stopper 320 in the second state S2 The blocking portion 322 and the positioning member 324 in the second state S2 cannot correspond to the positioning feature 338 of the first rail 302 through the positioning portion 326 . Therefore, the blocking member 320 and the positioning member 324 can directly move toward the retracting direction. D2 passes over the positioning feature 338 of the first rail 302 (as shown in FIG. 32 ), and when the second rail 310 is displaced to a predetermined stroke relative to the first rail 302 in the retracting direction D2 The second assist feature 306 contacts the first assist feature 304 of the first rail 302 (shown in FIG. 32 ).

如图32与图33所示,当该第二轨310相对该第一轨302进一步往该收合方向D2位移时,通过该第一辅助特征304挡止该第二辅助特征306时会产生作用力至该操作件305,使该操作件305从该第二操作位置P2(如图32所示)往开启方向D1回到该第一操作位置P1(如图33所示),令该挡件320与该定位件324分别通过该第一弹性特征334与该第二弹性特征336释放弹力而从该第二状态S2(如图32所示)回到该第一状态S1(如图33所示)。此外,该第二轨310可相对该第一轨302继续往该收合方向D2位移至收合位置R(例如完全收合位置,如图33所示)。其中,当该挡件320与该定位件324处于该第一状态S1时,该挡件320的挡部322与该定位件324的定位部326能对应该第一轨302的定位特征338。As shown in FIGS. 32 and 33 , when the second rail 310 is further displaced relative to the first rail 302 in the retracting direction D2 , the second auxiliary feature 306 is blocked by the first auxiliary feature 304 . Force is applied to the operating member 305 to make the operating member 305 return to the first operating position P1 (shown in Figure 33 ) from the second operating position P2 (as shown in FIG. 32 ) to the opening direction D1 (as shown in FIG. 33 ), so that the blocking member 320 and the positioning member 324 respectively release the elastic force through the first elastic feature 334 and the second elastic feature 336 to return from the second state S2 (as shown in FIG. 32 ) to the first state S1 (as shown in FIG. 33 ) ). In addition, the second rail 310 can continue to move in the retracting direction D2 relative to the first rail 302 to a retracted position R (eg, a fully retracted position, as shown in FIG. 33 ). When the blocking member 320 and the positioning member 324 are in the first state S1 , the blocking portion 322 of the blocking member 320 and the positioning portion 326 of the positioning member 324 can correspond to the positioning feature 338 of the first rail 302 .

如图34与图35所示,当该第二轨310相对该第一轨302从上述收合位置R往开启方向D1位移至一预定行程时,处于该第一状态S1的挡件320的挡部322会接触该第一轨302的定位特征338的后部338b。较佳地,该第一轨302的定位特征338的后部338b与该挡件320的挡部322的其中之一具有导引特征(例如斜面或弧面),有助于该挡件320的挡部322往该开启方向D1越过该定位特征338的后部338b。As shown in FIG. 34 and FIG. 35 , when the second rail 310 is displaced relative to the first rail 302 from the above-mentioned closed position R to the opening direction D1 to a predetermined stroke, the blocking member 320 in the first state S1 is blocked The portion 322 will contact the rear portion 338b of the locating feature 338 of the first rail 302 . Preferably, one of the rear portion 338b of the positioning feature 338 of the first rail 302 and the blocking portion 322 of the blocking member 320 has guiding The blocking portion 322 passes over the rear portion 338b of the positioning feature 338 in the opening direction D1.

如图36至图38所示,当该第二轨310相对该第一轨302继续往开启方向D1位移至第二延伸位置E2的过程中,该挡件320通过挡部322与该定位特征338的接触作用,使该挡件320不再处于该第一状态S1(如图36所示),此时,该第一弹性特征334累积一弹力,直到该第二轨310相对该第一轨302往开启方向D1位移至第二延伸位置E2时(如图37与图38所示),该挡件320响应该第一弹性特征334释放该弹力而再次地处于该第一状态S1(如图37与图38所示),此时,处于该第一状态S1的定位件324的定位部326,以及处于该第一状态S1的挡件320的挡部322分别对应该定位特征338的两个部位(例如后部338b与前部338a,如图37所示)可提供阻挡或卡掣效果,用以防止该第二轨310相对该第一轨302从该第二延伸位置E2往该开启方向D1或该收合方向D2位移(如图37与图38所示)。相同于上述第一实施例,当该第二轨310处于该第二延伸位置E2时,该滑轨总成300具有第二长度小于上述第一长度,如此有利于该第三轨316往该开启方向D1自该第二轨310的第二通道卸下。其中,当该第二轨310相对该第一轨302处于该第二延伸位置E2时,同样可通过该操作件305或该第三轨316带动该挡件320(与该定位件324),使该第二轨310可从该第二延伸位置E2离开(由于此部分已揭露于上述第二实施例,为了简明起见,在此不另赘述)。As shown in FIGS. 36 to 38 , when the second rail 310 continues to move relative to the first rail 302 in the opening direction D1 to the second extending position E2 , the blocking member 320 passes through the blocking portion 322 and the positioning feature 338 The contact action makes the blocking member 320 no longer in the first state S1 (as shown in FIG. 36 ). At this time, the first elastic feature 334 accumulates an elastic force until the second rail 310 is opposite to the first rail 302 When displaced in the opening direction D1 to the second extending position E2 (as shown in FIG. 37 and FIG. 38 ), the blocking member 320 is in the first state S1 again in response to the release of the elastic force of the first elastic feature 334 (as shown in FIG. 37 ). 38 ), at this time, the positioning portion 326 of the positioning member 324 in the first state S1 and the blocking portion 322 of the blocking member 320 in the first state S1 correspond to two parts of the positioning feature 338 respectively (For example, the rear portion 338b and the front portion 338a, as shown in FIG. 37) can provide a blocking or locking effect to prevent the second rail 310 from the second extending position E2 toward the opening direction D1 relative to the first rail 302 Or the retraction direction D2 is displaced (as shown in Figure 37 and Figure 38). Similar to the above-mentioned first embodiment, when the second rail 310 is in the second extending position E2, the sliding rail assembly 300 has a second length smaller than the above-mentioned first length, which facilitates the opening of the third rail 316 toward the The direction D1 is removed from the second channel of the second rail 310 . Wherein, when the second rail 310 is in the second extending position E2 relative to the first rail 302, the blocking member 320 (and the positioning member 324) can also be driven by the operating member 305 or the third rail 316, so that the The second rail 310 can be separated from the second extending position E2 (since this part has been disclosed in the above-mentioned second embodiment, for the sake of brevity, it will not be repeated here).

值得一提的是,请再参阅图31,一旦该挡件320被该操作件305驱动而处于该第二状态S2,使该阻挡特征318不能阻挡处于该第二状态S2的该挡件320的挡部322时,当该第二轨310相对该第一轨302从第一延伸位置E1往该收合方向D2位移的过程中,如果该操作件305因外界或非预期因素而从该第二操作位置P2回到该第一操作位置P1,此时,该操作件305的驱动部332便无法将该挡件320保持在该第二状态S2(例如该挡件320与该定位件324通过第一弹性特征334与第二弹性特征336的弹力回到该第一状态S1),使该挡件320的挡部322与该定位件324的定位部326对应该第一轨302的定位特征338,在此状态下,通过该第一轨302的定位特征338的前部338a与该定位件324的定位部326的其中之一具有导引特征(例如斜面或弧面),有助于该定位件324的定位部326往该收合方向D2越过该定位特征338的前部338a且该第二弹性特征336处于累积弹力的状态,直到该第二轨310继续往该收合方向D2位移至该第二延伸位置E2时(如图37与图38所示),该定位件324响应该第二弹性特征336释放该弹力而再次地处于该第一状态S1(如图37与图38所示),此时,处于该第一状态S1的定位件324的定位部326,以及处于该第一状态S1的挡件320的挡部322分别对应该定位特征338的两个部位(例如后部338b与前部338a,如图37所示)可提供阻挡或卡掣效果,用以防止该第二轨310相对该第一轨302从该第二延伸位置E2往该开启方向D1或该收合方向D2位移(如图37与图38所示)。It is worth mentioning that, referring to FIG. 31 again, once the blocking member 320 is driven by the operating member 305 to be in the second state S2, the blocking feature 318 cannot block the blocking member 320 in the second state S2 When the second rail 310 is displaced relative to the first rail 302 from the first extending position E1 to the retracting direction D2, if the operating member 305 is removed from the second rail 305 due to external or unexpected factors The operating position P2 returns to the first operating position P1, and at this time, the driving part 332 of the operating member 305 cannot keep the blocking member 320 in the second state S2 (for example, the blocking member 320 and the positioning member 324 pass through the first The elastic force of the first elastic feature 334 and the second elastic feature 336 returns to the first state S1), so that the blocking portion 322 of the blocking member 320 and the positioning portion 326 of the positioning member 324 correspond to the positioning feature 338 of the first rail 302, In this state, one of the front portion 338a of the locating feature 338 of the first rail 302 and the locating portion 326 of the locating member 324 has a guiding feature (eg, a sloped surface or a curved surface), which facilitates the locating member The positioning portion 326 of the 324 passes over the front portion 338a of the positioning feature 338 in the retracting direction D2 and the second elastic feature 336 is in a state of accumulating elastic force until the second rail 310 continues to move in the retracting direction D2 to the first position. In the second extended position E2 (as shown in FIGS. 37 and 38 ), the positioning member 324 is in the first state S1 again (as shown in FIGS. 37 and 38 ) in response to the second elastic feature 336 releasing the elastic force, At this time, the positioning portion 326 of the positioning member 324 in the first state S1 and the blocking portion 322 of the blocking member 320 in the first state S1 correspond to two parts of the positioning feature 338 (eg, the rear portion 338b and the front portion 338b respectively). portion 338a, as shown in FIG. 37) can provide a blocking or locking effect to prevent the second rail 310 from displacing relative to the first rail 302 from the second extending position E2 to the opening direction D1 or the retracting direction D2 (as shown in Figure 37 and Figure 38).

The slide rail assembly of claim 12 wherein the first rail is further provided with a stop feature; when the second rail moves from the extending position to the opening direction to another extending position relative to the first rail, the blocking feature can block the blocking piece in the first state so as to prevent the second rail from moving from the another extending position to the folding direction; when the second rail is at the other extending position, the sliding rail assembly has a first length; when the second rail is in the extended position, the slide rail assembly has a second length that is less than the first length.
14. The slide rail assembly of claim 13 wherein the operating member is operable to move from a first operating position to a second operating position to move the blocking member from the first state to the second state and to maintain the blocking member in the second state such that the blocking feature does not block the blocking member in the second state to allow the second rail to move from the extended position to the retracted position.
15. The slide rail assembly of claim 14 wherein the stopper drives the positioning element to the second state when the stopper is switched from the first state to the second state.
16. The slide rail assembly according to claim 15, wherein when the second rail is displaced from the other extending position to the retracting direction and the stopper and the positioning element are in the second state, the stopper and the positioning element can move past the positioning feature in the retracting direction until the second rail continues to move to a predetermined stroke in the retracting direction, a first auxiliary feature of the first rail and a second auxiliary feature of the operating element contact each other to generate an acting force on the operating element, so that the operating element returns from the second operating position to the first operating position, and the stopper and the positioning element return from the second operating position to the first operating position by elastic forces of a first elastic feature and a second elastic feature, respectively.
17. The slide rail assembly of claim 11 wherein the operating member is operatively mounted to the second rail.
18. The slide rail assembly of claim 17 wherein the operating member has a detent feature and the second rail has at least one predetermined portion for interengaging the detent feature to retain the operating member in at least the second operative position relative to the second rail.
19. The slide rail assembly according to claim 11, wherein when the second rail is located at the extended position relative to the first rail, the operating member is operable to move from a first operating position to a second operating position to drive the blocking member and the positioning member to change from the first state to the second state, such that the positioning member and the blocking member no longer correspond to two portions of the positioning feature of the first rail, so as to allow the second rail to move from the extended position to the opening direction or the retracting direction relative to the first rail.
20. The slide rail assembly of claim 11 further comprising a third rail, the second rail being movably mounted between the first rail and the third rail; when the second rail is located at the extending position relative to the first rail, the third rail can drive the blocking piece to be no longer in the first state in the process of moving from an opening position relative to the second rail to the folding direction, and the blocking piece can be linked with the positioning piece to be no longer in the first state, so that the positioning piece and the blocking piece are no longer corresponding to two parts of the positioning characteristic of the first rail, and the second rail is allowed to move from the extending position to the opening direction or the folding direction relative to the first rail.
