DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part of this application and which illustrate specific embodiments in which the invention may be practiced. In this regard, directional terms such as "up", "down", "left", "right", "front", "back" and the like are used with reference to the orientation of the figures being described. The components of the invention can be oriented in many different directions. As such, the directional terms are used for purposes of explanation and not limitation. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Unless otherwise specified, the term "connected" is intended to mean either an indirect or direct mechanical connection. Thus, when a first device is connected to a second device, the connection may be via a direct mechanical connection or via an indirect mechanical connection via other devices and connections.

[0011] As shown in FIGS. 1 to 3, the slide rail mechanism includes a first support member 22, a slide rail assembly 24, and at least one rotating member. A length M1 along the longitudinal direction of the slide rail assembly 24 is different from a length M2 along the longitudinal direction of the first support member 22. For example, as shown in FIG. 1, the length M1 along the longitudinal direction of the slide rail assembly 24 may be smaller than the length M2 of the first support member 22. Furthermore, the slide rail assembly 24 includes a first rail 26. The length along the longitudinal direction of the first rail 26 is smaller than the length M2 along the longitudinal direction of the first support member 22. In addition, the slide rail mechanism further includes a second support member 34 connected to the first support member 22, and the length along the longitudinal direction of the first rail 26 is smaller than the length along the longitudinal direction of the second support member 34. The first rail 26 and the first support member 22 are displaceable relative to each other. In this embodiment, by way of example, the longitudinal direction may be defined by the length or displacement direction of the slide rail, e.g., first rail 26, parallel to the X-axis. The lateral direction may be defined by the lateral or width direction of the slide rail, e.g., first rail 26, parallel to the Y-axis. The vertical direction may be defined by the height direction of the slide rail, e.g., first rail 26, parallel to the Z-axis. The second support member 34 may be a support frame configured to enable the first support member 22 and slide rail assembly 24 to be mounted to a rack.

[0012] In this embodiment, by way of example, the at least one rotating member may include a first rotating member 25a, e.g., a front rotating member, and a second rotating member 25b, e.g., a rear rotating member. The first rotating member 25a and the second rotating member 25b are configured to facilitate displacement of the first rail 26 and the first support member 22 relative to each other. However, the present invention is not limited to this embodiment. For example, in another embodiment, the slide rail mechanism may include only one rotating member.

[0013] The first rotating member 25a and the second rotating member 25b are preferably disposed on one of the first rail 26 and the first support member 22, and are in rotatable contact with the other of the first rail 26 and the first support member 22. In this embodiment, as an example, the first rotating member 25a and the second rotating member 25b can be disposed on the first rail 26, spaced apart from each other by a distance along the longitudinal direction. In addition, the first rotating member 25a is pivotally connected to the first mounting member 29a by the first shaft 27a, and the second rotating member 25b is pivotally connected to the second mounting member 29b by the second shaft 27b. In this embodiment, as an example, the first mounting member 29a and the second mounting member 29b can be fixedly connected to the first rail 26, and therefore can be considered as a part of the first rail 26. Of course, in other embodiments, the first mounting member and the second mounting member can be detachably connected to the first rail.

[0014] The slide rail mechanism preferably further includes a slide rail device 32. The slide rail device 32 includes a first support member 22 and a second support member 34. In this embodiment, as an example, the first support member 22 and the second support member 34 can be fixedly connected to each other, and therefore can be considered as an integral structure. However, the present invention is not limited to this embodiment. The first rotating member 25a and the second rotating member 25b are displaceable together with the first rail 26. Furthermore, the first rail 26 is displaceable along the longitudinal direction relative to the first support member 22 by the first rotating member 25a and the second rotating member 25b. The configuration of the first rotating member 25a and the second rotating member 25b can reduce the frictional force resisting the displacement of the first rail 26 relative to the first support member 22, and ensure the smooth displacement of the first rail 26 relative to the first support member 22.

[0015] The first rotating member 25a and the second rotating member 25b are preferably members having an arc-shaped profile, such as rollers or balls, for example, although the present invention is not limited to such a configuration.

[0016] The slide rail assembly 24 further includes a second rail 28 and a third rail 30. In this embodiment, by way of example, the first rail 26, the second rail 28 and the third rail 30 may be an outer rail, a middle rail and an inner rail, and the second rail 28 may be movably mounted between the first rail 26 and the third rail 30.

[0017] The second support member 34 preferably includes a release portion 36 and a block portion 37 disposed adjacent to the release portion 36. In this embodiment, by way of example, the release portion 36 may be formed by drilling and the block portion 37 may be a wall. However, the present invention is not limited to this embodiment.

[0018] The first support member 22 is preferably provided with a blocking portion 38. In this embodiment, as an example, the first support member 22 can include a bracket 40 located adjacent an end, such as a front end, of the first support member 22, and the blocking portion 38 can be disposed on the bracket 40.

[0019] The first support member 22 preferably further includes a support passage configured to at least partially receive a plurality of movable rails, for example, the first movable rail 42 and the second movable rail 44. The first movable rail 42 is located between the first support member 22 and the second movable rail 44. The length along the longitudinal direction of the third rail 30 of the slide rail assembly 24 is smaller than the length along the longitudinal direction of the second movable rail 44 of the slide rail device 32. Note that the third rail 30 of the slide rail assembly 24 is configured to support a first object (not shown), and the second movable rail 44 of the slide rail device 32 is configured to support a second object (not shown). After the second object is removed from the second movable rail 44 or after both the second movable rail 44 and the second object are removed from the first movable rail 42, the first rail 26 of the slide rail assembly 24 can be displaced along the longitudinal direction relative to the first support member 22 and / or the second support member 34 of the slide rail device 32 by the first rotating member 25a and the second rotating member 25b. During the longitudinal displacement of the first rail 26 or the slide rail assembly 24 relative to the first support member 22 or the slide rail device 32, the configuration of the first rotating member 25a and the second rotating member 25b can reduce the frictional force resisting the longitudinal displacement of the first rail 26 or the slide rail assembly 24 relative to the first support member 22 or the slide rail device 32. Therefore, the present invention can obtain a protective effect.

[0020] The slide rail assembly 24 preferably further includes a first backing member 46 and a second backing member 48. The first backing member 46 is disposed on the first rail 26. The second backing member 48 is disposed on the second rail 28.

[0021] Preferably, one of the first auxiliary member 46 and the second auxiliary member 48 is movable. The other of the first auxiliary member 46 and the second auxiliary member 48 is immovable. In this embodiment, by way of example, the first auxiliary member 46 can be pivotally connected to the first rail 26 by a shaft 50 such that the first auxiliary member 46 can pivot relative to the first rail 26. The second auxiliary member 48 can be fixedly connected to the second rail 28.

[0022] The slide rail assembly 24 preferably further includes an auxiliary rail 52 disposed on the first rail 26. The first rail 26 is movably attached to one of the first support member 22 and the second support member 34 by the auxiliary rail 52. Furthermore, the auxiliary rail 52 includes a first auxiliary wall 54a, a second auxiliary wall 54b, and an intermediate wall 56 connected between the first auxiliary wall 54a and the second auxiliary wall 54b. The intermediate wall 56 is connected to the first side L1 of the first rail 26. As shown in FIG. 3, in this embodiment, as an example, the intermediate wall 56 is fixedly connected to the first side L1 of the first rail 26, and the first side L1 of the first rail 26 may be the back side of the first rail 26 located adjacent to the first support member 22 or the second support member 34. The first auxiliary wall 54a and the second auxiliary wall 54b are configured to hold the first support member 22 or the second support member 34. In this embodiment, as an example, the first auxiliary wall 54a and the second auxiliary wall 54b can hold the first wall 57a and the second wall 57b of the first support member 22, respectively, and the first wall 57a and the second wall 57b of the first support member 22 can be the upper wall and the lower wall of the first support member 22, respectively. However, the present invention is not limited to this embodiment. In addition, as shown in FIG. 3, the second rail 28 is at least partially movably mounted within a first passage of the first rail 26 formed on a second side L2 of the first rail 26 opposite to the first side L1 of the first rail 26. Furthermore, the third rail 30 is at least partially movably mounted within a second passage of the second rail 28.

[0023] 3, the slide rail assembly 24 preferably further includes an action member 58 movably mounted on the second rail 28. A corresponding portion 60 is disposed on the third rail 30 and configured to cooperate with the action member 58. The third rail 30 can drive the second rail 28 to be displaced synchronously together with the third rail 30 by abutment between the corresponding portion 60 and the action member 58.

[0024] The application member 58 is preferably pivotally connected to the second rail 28 by a connecting member 62 .

[0025] A retaining member 64 is preferably disposed on the first rail 26. In this embodiment, by way of example, the retaining member 64 may be an elastic element, such as an elastic plate. However, the invention is not limited to this embodiment. The retaining member 64 includes a release structure 66 and a block structure 68 adjacent to the release structure 66. In this embodiment, by way of example, the release structure 66 may be an inclined or arcuate surface, and the block structure 68 may be a wall, such as a vertical wall. However, the invention is not limited to this embodiment. Of course, in other embodiments, the release structure and / or the block structure may be integrally connected to the first rail.

[0026] As shown in Figures 4 and 5, the slide rail assembly 24 is in a retracted state relative to the first support member 22 or the slide rail device 32. As shown in Figure 5, the second auxiliary member 48 can abut against the first auxiliary member 46 to drive the first rail 26 to displace together with the second rail 28 while the second rail 28 displaces along the first predetermined direction D1 away from the first predetermined position P1. In addition, while the third rail 30 displaces along the first predetermined direction D1, the second rail 28 is driven by the third rail 30 to displace synchronously together with the third rail 30 due to the abutment of the corresponding portion 60 and the working member 58. Therefore, when the third rail 30 is operated to displace along the first predetermined direction D1, the second rail 28 can be displaced synchronously together with the third rail 30, and the first rail 26 can be displaced synchronously together with the second rail 28. That is, the third rail 30, the second rail 28 and the first rail 26 can be displaced together synchronously along the first predetermined direction D1. While the first rail 26 is displaced along the first predetermined direction D1, the first rail 26 engages with the first wall 57a of the first support member 22 via the first rotating member 25a and the second rotating member 25b, and the configuration of the first rotating member 25a and the second rotating member 25b can reduce the frictional force resisting the displacement of the first rail 26 relative to the first support member 22 along the first predetermined direction D1 by rotating relative to the first wall 57a, e.g., the upper wall, of the first support member 22. In addition, the first wall 57a, e.g., the upper wall, of the first support member 22 can support the first rotating member 25a and the second rotating member 25b to increase the supporting strength of the first rail 26 or the slide rail assembly 24. It is preferable that the first auxiliary wall 54a and the second auxiliary wall 54b of the auxiliary rail 52 hold the first wall 57a and the second wall 57b, respectively, thereby promoting stability and reliability of displacement of the first rail 26 relative to the first support member 22 along the first predetermined direction D1.

[0027] As shown in Fig. 5, the slide rail assembly 24 preferably further includes an elastic member 70. The first auxiliary member 46 is held in the first state S1 to abut against the second auxiliary member 48 in response to an elastic force provided by the elastic member 70 and / or the support of the second support member 34. As shown in Figs. 4 and 5, in this embodiment, as an example, the second auxiliary member 48 may include at least one abutment portion 72, such as a hook portion or a hook-like structure, configured to abut against a corresponding portion 69 of the first auxiliary member 46 to drive the first rail 26 to displace synchronously together with the second rail 28 while the second rail 28 is displaced along the first predetermined direction D1 away from the first predetermined position P1.

[0028] The elastic member 70 is preferably disposed on the first side L1 of the first rail 26 and is hidden between the first rail 26 and the first support member 22 or between the first rail 26 and the slide rail device 32. In this embodiment, as an example, the elastic member 70 may be an elastic plate. However, the present invention is not limited to this embodiment. As shown in FIG. 5, the elastic member 70 has at least one elastic portion 71 for providing an elastic force to at least one extension portion 73 of the first auxiliary member 46, and the second support member 34 supports the first auxiliary member 46 so that the first auxiliary member 46 is held in the first state S1.

[0029] As shown in FIG. 6, the release portion 36 of the second support member 34 is configured to terminate the synchronization of the displacement of the second rail 28 and the first rail 26 when the second rail 28 and the first rail 26 are synchronously displaced to a second predetermined position P2 along the first predetermined direction D1.

[0030] When the first rail 26 is located at the second predetermined position P2, the release portion 36 of the second support member 34 is configured to provide a movement space for the first auxiliary member 46, release the elastic member 70, and drive the first auxiliary member 46 to move from the first state S1 to the second state S2, for example, pivot along a predetermined pivot direction R, so that the corresponding portion 69 of the first auxiliary member 46 can move to deviate from at least one abutment portion 72 of the second auxiliary member 48 in a longitudinal direction, for example along the X-axis, to terminate the displacement synchronization between the second rail 28 and the first rail 26.

[0031] When the first auxiliary member 46 is in the second state S2, the block portion 37 of the second support member 34 can block the first auxiliary member 46 to prevent the first rail 26 from displacing from the second predetermined position P2 along a second predetermined direction opposite to the first predetermined direction D1, for example, the retracting direction D2. Furthermore, the block portion 38 of the first support member 22 can block one of the first rail 26 and the auxiliary rail 52 to prevent the first rail 26 from displacing away from the second predetermined position P2 along the first predetermined direction D1. In this embodiment, as an example, the block portion 38 provided on the bracket 40 of the first support member 22 can block the first mounting member 29a of the first rail 26. However, the present invention is not limited to this embodiment.

[0032] In Figs. 7 to 13, for the sake of simplicity, the first rotating member 25a, the second rotating member 25b, the first mounting member 29a, and the second mounting member 29b are not illustrated. As shown in Figs. 7 and 8, the slide rail assembly 24 further includes at least one first sliding assist device 74 and a second sliding assist device 76. The at least one first sliding assist device 74 is movably attached between the second rail 28 and the first rail 26 to facilitate smooth displacement of the second rail 28 relative to the first rail 26. The second sliding assist device 76 is movably attached between the second rail 28 and the third rail 30 to facilitate smooth displacement of the third rail 30 relative to the second rail 28. In this embodiment, as an example, the first sliding assist device 74 can include a plurality of first sliding assist members 78, and the second sliding assist device 76 can include a plurality of second sliding assist members 80. The first slide assist member 78 or the second slide assist member 80 may be a ball, a roller, or the like.

[0033] Specifically, when the third rail 30 does not displace relative to the second rail 28 along the first predetermined direction D1 during the displacement of the second rail 28 from the first predetermined position P1 to the second predetermined position P2, the corresponding portion 60 of the third rail and the acting member 58 of the second rail 28 are spaced apart by a predetermined distance along the longitudinal direction. While the third rail 30 displaces along the first predetermined direction D1, it is preferable that the third rail 30 drives the second rail 28 to displace along the first predetermined direction D1 by the frictional force between the third rail 30 and the second rail 28 as shown in FIG. 7 before the corresponding portion 60 abuts against the acting member 58. Thereafter, the third rail 30 drives the second rail 28 to displace synchronously together with the third rail 30 by the abutment between the corresponding portion 60 and the acting member 58 as shown in FIG. 8 after the abutment between the corresponding portion 60 and the acting member 58.

[0034] The third rail 30 preferably includes a first wall 82a and a second wall 82b, and the corresponding portion 60 is disposed on the first wall 82a of the third rail 30. For example, the corresponding portion 60 can be a hole wall of the hole H. The first wall 82a of the third rail 30 can support the working member 58 to hold the working member 58 in an initial state K1 as shown in FIG. 7. During the displacement of the third rail 30 along the first predetermined direction D1, the hole H formed in the third rail 30 moves to a position corresponding to the synchronous portion 84 of the working member 58 in response to the elastic force provided by the elastic body 86 to move, for example pivot, the working member 58 from the initial state K1 to a predetermined position K2 shown in FIG. 8, so that the corresponding portion 60 of the third rail 30 abuts against the synchronous portion 84 of the working member 58, and the third rail 30 can drive the second rail 28 to be displaced synchronously with the third rail 30 as shown in FIG. 8.

[0035] 8, the second rail 28 preferably includes a through hole 88 through which an acting portion 90 of the acting member 58 extends toward the first rail 26. The acting portion 90 of the acting member 58 can cooperate with a retaining member 64 of the first rail 26, such as the release structure 66 and the blocking structure 68 of the retaining member 64.

[0036] When the third rail 30 drives the second rail 28 to synchronously displace together with the third rail 30 from the position shown in FIG. 8 to the release position shown in FIG. 9, the release structure 66 of the first rail 26 is configured to terminate the displacement synchronization between the third rail 30 and the second rail 28. In this embodiment, as an example, the action portion 90 of the action member 58 of the second rail 28 is guided by the release structure 66 of the first rail 26 to drive the action member 58 to move away from the predetermined state K2, for example, to pivot by a predetermined angle, so that the corresponding portion 60 of the third rail 30 does not abut against the synchronization portion 84 of the action member 58 in order to terminate the synchronous displacement between the third rail 30 and the second rail 28. After the synchronous displacement between the third rail 30 and the second rail 28 is completed, the third rail 30 and the second rail 28 can be individually displaced along the first predetermined direction D1 relative to the first rail 26. In addition, when the acting member 58 is in the state shown in FIG. 9, the elastic body 86 is elastically deformed.

[0037] As shown in Fig. 10, when the second rail 28 is further displaced to the third predetermined position P3 along the first predetermined direction D1, the block structure 68 of the first rail 26 is configured to block the second rail 28 to prevent the second rail 28 from displacing away from the third predetermined position P3 along the second predetermined direction D2. In this embodiment, as an example, when the second rail 28 is located at the third predetermined position P3, the elastic object 86 is released to drive the action member 58 to move to the position shown in Fig. 10 so that the action portion 90 of the action member 58 can be blocked by the block structure 68 of the first rail 26 to prevent the second rail 28 from displacing away from the third predetermined position P3 along the second predetermined direction D2.

[0038] It is preferable that a first restraining portion 92 is further disposed on the first rail 26, and a second restraining portion 94 is further disposed on the second rail 28. When the second rail 28 is located at the third predetermined position P3, the front end and the rear end of the first sliding assist device 74 abut against the first restraining portion 92 and the second restraining portion 94, respectively, to prevent the second rail 28 from displacing away from the third predetermined position P3 along the first predetermined direction D1.

[0039] 11 , when the second rail 28 is located at the third predetermined position P3, the third rail 30 can be further displaced along the first predetermined direction D1 to a fourth predetermined position P4 to position the slide rail assembly 24 in an extended state, e.g., fully extended state, relative to the first support member 22 or the slide rail device 32. When the third rail 30 is located at the fourth predetermined position P4, the second sliding assist device 76 is located adjacent to an end, e.g., a front end, of the second rail 28.

[0040] As shown in Figures 12 and 13, the third rail 30 is configured to terminate the blocking relationship between the blocking structure 68 and the second rail 28 while the third rail 30 is displaced away from the fourth predetermined position P4 along the second predetermined direction D2. Further, as shown in Figures 12 and 13, a part of the third rail 30, for example, the rear end r, is configured to abut against the synchronization portion 84 of the working member 58 to drive the working member 58, so as to prevent the working portion 90 of the working member 58 of the first rail 26 from being blocked by the blocking structure 68 of the first rail 26. When the working portion 90 of the working member 58 is not blocked by the blocking structure 68 of the first rail 26, the second rail 28 can be displaced away from the third predetermined position P3 along the second predetermined direction D2.

[0041] As shown in Figures 14 and 15, one of the second rail 28 and the first auxiliary member 46 includes a first guide portion 96. The other of the second rail 28 and the first auxiliary member 46 preferably includes a second guide portion 98 for cooperating with the first guide portion 96. As shown in Figure 3, in this embodiment, as an example, the second rail 28 includes the first guide portion 96 disposed on the second auxiliary member 48, the first auxiliary member 46 includes the second guide portion 98, and the first guide portion 96 and the second guide portion 98 may be inclined surfaces or arc surfaces. However, the present invention is not limited to this embodiment.

[0042] The second rail 28 is configured to terminate the blocking relationship between the block portion 37 and the first rail 26 while the second rail 28 is displaced away from the third predetermined position P3 along the second predetermined direction D2. In this embodiment, as an example, the first guide portion 96 of the second rail 28 can abut the second guide portion 98 of the first auxiliary member 46 to drive the first auxiliary member 46 from the second state S2 shown in FIG. 14 to the first state S1 shown in FIG. 15 so that the block portion 37 of the second support member 34 does not block the first auxiliary member 46 of the first rail 26 and the auxiliary rail 52 can be displaced away from the second predetermined position P2 along the second predetermined direction D2. Thus, the third rail 30, the second rail 28 and the first rail 26 can be displaced along the second predetermined direction D2 until the slide rail assembly 24 returns to the retracted state shown in FIG. 4. While the first rail 26 or slide rail assembly 24 is displaced along the second predetermined direction D2 relative to the first support member 22 or slide rail device 32, the configuration of the first rotating member 25a and the second rotating member 25b can reduce the frictional force resisting when the first rail 26 or slide rail assembly 24 is displaced along the second predetermined direction D2 relative to the first support member 22 or slide rail device 32 by rotating the first rotating member 25a and the second rotating member 25b against the first wall 57a, e.g., the upper wall, of the first support member 22. In addition, the first wall 57a, e.g., the upper wall, of the first support member 22 can support the first rotating member 25a and the second rotating member 25b to increase the support strength of the first rail 26 or slide rail assembly 24.

[0043] It should be noted that the slide rail assembly 24 can be adapted to a rack, and the third rail 30 can be configured to support a first object, such as an electronic device or a drawer. The slide rail assembly 24 can ensure that the second rail 28 and the first rail 26 are displaced synchronously, and prevent the third rail 30 and the second rail 28 from being pulled out along the first predetermined direction D1 without the displacement of the first rail 26. Thus, the slide rail assembly 24 can solve the technical problem that when the third rail and the second rail are pulled out without the displacement of the first rail, it takes a lot of effort to pull out the first rail due to excessive friction between the first rail and the support frame and / or between the first rail and the support rail, e.g., due to the weight of the held object. In addition, the configuration of the first rotating member 25a and the second rotating member 25b can reduce the frictional force resisting displacement of the first rail 26 or the slide rail assembly 24 relative to the first support member 22 or the slide rail device 32 along the first predetermined direction D1 and the second predetermined direction D2 due to the rotational movement of the first rotating member 25a and the second rotating member 25b relative to the first wall 57a, e.g., the upper wall, of the first support member 22.

[0044] As shown in Fig. 16, the first support member 22 and each of the first rotating member 25a and the second rotating member 25b have two cooperating portions configured to cooperate with each other. Furthermore, one of the first support member 22 and each of the first rotating member 25a and the second rotating member 25b includes a first cooperating portion 100, and the other of the first support member 22 and the first rotating member 25a and the second rotating member 25b includes a second cooperating portion 102 configured to cooperate with the first cooperating portion 100. In this embodiment, as an example, each of the first rotating member 25a and the second rotating member 25b can include the first cooperating portion 100, and the first support member 22 can include the second cooperating portion 102.

[0045] Specifically, the first cooperating portion 100 may be a groove structure, and the second cooperating portion 102 may be a protruding end extending along the longitudinal direction configured to abut against the groove structure to enhance stability and reliability of the longitudinal rotational movement of the first rotating member 25a and the second rotating member 25b relative to the first wall 57a of the first support member 22.

[0046] As described above, the slide rail assembly 24 has the following features.

[0047] 1. The configuration of at least one rotating member, e.g., first rotating member 25a and / or second rotating member 25b, disposed on first rail 26 of slide rail assembly 24 can reduce frictional forces resisting displacement of first rail 26 or slide rail assembly 24 relative to first support member 22 along first predetermined direction D1 and second predetermined direction D2.

[0048] 2. The second rail 28 is synchronously displaceable along the first predetermined direction D1 together with the first rail 26 and / or the third rail 30 is synchronously displaceable along the first predetermined direction D1 together with the second rail 28.

[0049] 3. At least one rotating member, e.g., the first rotating member 25a and / or the second rotating member 25b, the first support member 22 each includes a first cooperating portion 100 and a second cooperating portion 102 configured to cooperate with the first cooperating portion 100 to enhance stability and reliability of the rotational movement along the longitudinal direction of the first rotating member 25a and the second rotating member 25b relative to the first support member 22.

[0050] Those skilled in the art will readily appreciate that numerous modifications and variations of the apparatus and method may be made while retaining the teachings of this invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
