Description

Technical Field

[0001] The present invention relates to a slide rail assembly, and more particularly to a slide rail assembly having an auxiliary member configured to desynchronize movement between two slide rails.

Background Art

[0002] U.S. Patent No. 7,357,468 discloses a slide assembly comprising an outer rail, an intermediate rail, and an inner rail. The intermediate rail is movably mounted between the outer rail and the inner rail. The outer rail, intermediate rail, and inner rail are longitudinally movable relative to each other. A connecting member, a positioning member, and an elastic member are disposed on the intermediate rail. The connecting member and the positioning member are pivotally connected to the intermediate rail. A first projection wall, including a block portion and an inclined portion, is disposed on the inner rail. A second projection wall, including a retaining portion and an inclined portion, is disposed on the outer rail. The connecting member includes a constrained end and an open end. The positioning member includes an open end and a fixed end. The elastic member is configured to provide an elastic force for holding the open end of the connecting member and the fixed end of the positioning member. The constrained end of the connecting member corresponds to the block portion of the first projection wall of the inner rail, and the open end of the connecting member corresponds to the inclined portion of the second projection wall. The fixed end of the positioning member corresponds to the retaining portion of the second protruding wall of the outer rail, and the released end of the positioning member corresponds to the inclined portion of the first protruding wall. When the slide assembly is fully retracted, the constrained end of the connecting member abuts against the block portion of the first protruding wall, and the released end of the positioning member is lifted by the first protruding wall. When the inner rail is pulled out, the intermediate rail is pulled out simultaneously by the block portion of the first protruding wall and the constrained end of the connecting member. After the inner rail has moved to a predetermined position, the released end of the connecting member is lifted by the inclined portion of the second protruding wall, disengaging the constrained end of the connecting member from the block portion of the first protruding wall, thereby disengaging the connecting member from the inner rail (de-synchancing the movement between the intermediate rail and the inner rail). When the inner rail is pulled out further, the first protruding wall separates from the released end of the positioning member, thereby pressing the fixed end of the positioning member against the second elastic leg of the elastic member and fastening it to the retaining portion of the second protruding wall. As the inner rail continues to be pulled out, the fixed end of the positioning member comes into contact with the holding portion of the second protruding wall, thereby positioning the intermediate rail relative to the outer rail and allowing the inner rail to be pulled out further to its fully extended position.

[0003] The aforementioned slide assembly can de-synchronously move between the intermediate rail and the inner rail by lifting the open end of the connecting member of the intermediate rail with the inclined portion of the second protruding wall, thereby detaching the constrained end of the connecting member from the block portion of the first protruding wall. However, if an unexpected gap exists between the intermediate rail and the inner rail due to mounting tolerances, the slide assembly may not be able to de-synchronously move between the intermediate rail and the inner rail. Therefore, it is important to develop various slide rail products to meet the demands of different markets. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] U.S. Patent No. 7,357,468 [Overview of the project]

[0005] The present invention provides a slide rail assembly having an auxiliary member configured to asynchronously move between two slide rails.

[0006] According to one embodiment of the present invention, a slide rail assembly comprises a first rail, a second rail, a synchronous member, an engaging member, an auxiliary member, and a third rail. A predetermined mechanism and a block mechanism are arranged on the first rail. The second rail is longitudinally movable relative to the first rail. The synchronous member, the engaging member, and the auxiliary member are movably mounted on the second rail. The third rail is longitudinally movable relative to the second rail and has an operating mechanism. As the third rail moves along the opening direction, the third rail is configured to drive the second rail to move synchronously by the operating mechanism contacting the synchronous member in a first state. As the third and second rails move synchronously along the opening direction, the block mechanism is configured to contact the auxiliary member, moving the auxiliary member from a first auxiliary position to a second auxiliary position relative to the second rail, and to drive the synchronous member to switch from a first state to a second state, thereby preventing the operating mechanism of the third rail from contacting the synchronous member, and making the movement between the third rail and the second rail asynchronous. When the second rail is in the extended position relative to the first rail, the engaging member is configured to engage with a predetermined mechanism to prevent the second rail from moving from the extended position along the retracted direction.

[0007] According to another embodiment of the present invention, the slide rail assembly comprises a first rail, a second rail, a synchronous member, an auxiliary member, and a third rail. A block mechanism is disposed on the first rail. The second rail is longitudinally movable relative to the first rail. The synchronous member is movably mounted on the second rail. The auxiliary member is movable relative to the second rail between a first auxiliary position and a second auxiliary position. The third rail is longitudinally movable relative to the second rail and has an action mechanism disposed on it. As the third rail moves along the opening direction, the third rail is configured to drive the second rail to move synchronously by the action mechanism contacting the synchronous member. As the third and second rails move synchronously along the opening direction, the block mechanism is configured to contact the auxiliary member and move the auxiliary member linearly relative to the second rail from the first auxiliary position to the second auxiliary position, thereby driving the synchronous member to move, so that the action mechanism of the third rail does not contact the synchronous member, and the movement between the third rail and the second rail is asynchronous.

[0013] The third rail 26 includes a first wall 46a, a second wall 46b, and a longitudinal wall 48 connected between the first wall 46a and the second wall 46b of the third rail 26. An operating mechanism 45 is positioned on the longitudinal wall 48 of the third rail 26. The operating mechanism 45 may be a hole or groove defined by a plurality of inner walls of the third rail 26, but the present invention is not limited thereto.

[0014] Preferably, a first slide support device 47 is positioned between the first rail 22 and the second rail 24. The first slide support device 47 includes a plurality of balls configured to improve the smoothness of the movement of the second rail 24 relative to the first rail 22. A second slide support device 49 is positioned between the second rail 24 and the third rail 26. The second slide support device 49 includes a plurality of balls configured to improve the smoothness of the movement of the third rail 26 relative to the second rail 24.

[0015] As shown in FIGS. 3 to 5, the slide rail assembly 20 further includes a synchronization member 50, an engagement member 52, and an auxiliary member 54 disposed on the second rail 24. Preferably, the slide rail assembly 20 further includes an elastic structure 56.

[0016] The second rail 24 has a first end 24a and a second end 24b such as a front end and a rear end. Further, the second rail 24 has a first side L1 and a second side L2 on opposite sides of each other such as an outer side and an inner side. The first side L1 is adjacent to (or faces) the first rail 22, and the second side L2 is adjacent to (or faces) the third rail 26.

[0017] Preferably, at least one through hole is formed in the longitudinal wall 42 of the second rail 24. In the present embodiment, a first through hole H1 and a second through hole H2 that communicate the first side L1 and the second side L2 of the second rail 24 are formed in the longitudinal wall 42 of the second rail 24.

[0018] Preferably, the synchronization member 50, the engagement member 52, and the auxiliary member 54 are movably attached to the second rail 24. The synchronization member 50 and the engagement member 52 are located at different height positions along the height direction (Z-axis direction) of the second rail 24. The synchronization member 50 and the latch member 52 are pivotally connected to the second rail 24 via a shaft member 58, and the synchronization member 50 and the latch member 52 are respectively received in the first through hole H1 and the second through hole H2. The perforated H2. The arrangement direction of the shaft member 58 is substantially the same as the height direction (Z-axis direction) of the second rail 24.

[0019] Preferably, the synchronization member 50, the engagement member 52, and the auxiliary member 54 are adjacent to the second end 24b of the second rail 24.

[0020] The synchronous member 50 comprises a first portion 50a, a second portion 50b, and an intermediate portion 50c located between the first portion 50a and the second portion 50b. On the other hand, the engaging member 52 comprises a first section 52a, a second section 52b, and an intermediate section 52c located between the first section 52a and the second section 52b. Preferably, the shaft member 58 penetrates the intermediate portion 50c of the synchronous member 50 and the intermediate section 52c of the engaging member 52, thereby pivotably connecting the synchronous member 50 and the engaging member 52 to the longitudinal wall 42 of the second rail 24.

[0021] The elastic structure 56 is configured to provide elastic force to at least one of the synchronous member 50 and the engaging member 52. In this embodiment, the elastic structure 56 is an elastic piece comprising a first elastic arm 56a and a second elastic arm 56b configured to provide elastic force to the synchronous member 50 and the engaging member 52, respectively, but the present invention is not limited thereto. Preferably, the first elastic arm 56a and the second elastic arm 56b abut against the second portion 50b of the synchronous member 50 and the second section 52b of the engaging member 52, respectively.

[0022] The auxiliary member 54 is linearly movable relative to the second rail 24. In this embodiment, the auxiliary member 54 is linearly movable relative to the second rail 24 along the longitudinal direction (X-axis direction). Preferably, the auxiliary member 54 and the second rail 24 (longitudinal wall 42 of the second rail 24) are respectively provided with a first restricting mechanism 60 (at least one first restricting mechanism 60) and a second restricting mechanism 62 (at least one first restricting mechanism 60) configured to interact with each other. For example, the first restricting mechanism 60 can be an elongated hole in the longitudinal direction, and the second restricting mechanism 62 can be a protruding part (such as a pin or bolt) passing through the elongated hole in the longitudinal direction, but the present invention is not limited thereto.

[0023] Preferably, the slide rail assembly 20 further includes an elastic member 64 configured to provide elastic force to the auxiliary member 54. The elastic member 64 is connected between the second rail 24 and the auxiliary member 54. In this invention, the elastic member 64 is integrated with the auxiliary member 54, but the invention is not limited thereto. One end 64 of the elastic member 64 is connected to the longitudinal wall 42 of the second rail 24.

[0024] Preferably, the auxiliary member 54 has a first end 54a and a second end 54b that are opposite to each other. The first end 54a and the elastic member 64 are connected to each other. The auxiliary member 54 has an auxiliary portion 66 positioned adjacent to the first end 54a. The auxiliary portion 66 can be a protruding wall extending along the transverse direction. The auxiliary member 54 has a guide portion 68 positioned adjacent to the second end 54b. The guide portion 68 has an inclined surface or an arcuate surface, but the present invention is not limited thereto. The auxiliary portion 66 is configured to interact with the block mechanism 30 on the first rail 22, and the guide portion 68 is configured to interact with the second portion 50b of the synchronous member 50.

[0025] As shown in Figures 6 and 7, the slide rail assembly 20 is in the retracted position, with the second rail 24 and the third rail 26 in the retracted position R relative to the first rail 22. The engaging member 52 is separated from a predetermined part 38 (a predetermined mechanism 28 of the predetermined part 38) by a first longitudinal distance along the longitudinal direction (X-axis direction). The auxiliary member 54 is separated from the block mechanism 30 by a second longitudinal distance along the longitudinal direction. In Figures 6 and 7, the auxiliary member 54 is positioned at a first auxiliary position M1 relative to the second rail 24. In addition, the first elastic arm 56a is configured to abut against the second portion 50b of the synchronous member 50 and apply an elastic force, and the second elastic arm 56b is configured to abut against the second section 52b of the engaging member 52 and apply an elastic force. On the other hand, both the first portion 50a of the synchronous member 50 and the first section 52a of the engaging member 52 abut against the longitudinal wall 48 of the third rail 26. A hook 70 is positioned in the second section 52b of the engaging member 52.

[0026] As shown in Figure 8, during the process in which the third rail 26 moves from the storage position R along the opening direction D1, the third rail 26 is configured to move in sync with the first rail 22 along the opening direction D1 by driving the second rail 24 through the action mechanism 45 contacting the synchronization member 50 in the first state S1.

[0027] Specifically, as the third rail 26 moves along the opening direction D1, the operating mechanism 45 of the third rail 26 corresponds to the extension section 72 of the first portion 50a of the synchronization member 50. Meanwhile, the synchronization member 50 is configured to be held in a first state S1 according to the elastic force of the first elastic arm 56a. At the same time, the extension section 72 and the operating mechanism 45 of the third rail 26 are configured to be in contact with (or abut against) each other, thereby configuring the third rail 26 to drive the second rail 24 to move synchronously along the opening direction D1.

[0028] As shown in Figures 9 to 11, when the third rail 26 and the second rail 24 move synchronously to a predetermined position along the opening direction D1, the block mechanism 30 and the auxiliary portion 66 of the auxiliary member 54 are configured to come into contact with each other, thereby allowing the block mechanism 30 to apply a force F to move the auxiliary portion 66 of the auxiliary member 54. For example, the block mechanism 30 is configured to block the auxiliary portion 66 of the auxiliary member 54, thereby causing the auxiliary portion 54 to move longitudinally from a first auxiliary position M1 (shown in Figure 10) to a second auxiliary position M2 (shown in Figure 11) relative to the second rail 24 in response to the applied force F. Therefore, the guide portion 68 of the auxiliary member 54 is configured to contact the second portion 50b of the synchronization member 50, overcome the elastic force of the first elastic arm 56a, drive the synchronization member 50 to move (rotate), and switch from the first state S1 to the second state S2 (shown in Figure 11). As a result, the operating mechanism 45 of the third rail 26 no longer contacts the extension section 72 of the synchronization member 50, and the movement between the third rail 26 and the second rail 24 is made asynchronous.

[0029] As shown in Figures 12 and 13, when the auxiliary member 54 is positioned at the second auxiliary position M2 relative to the second rail 24, the blocking mechanism 30 and the auxiliary portion 66 of the auxiliary member 54 are configured to block each other, thereby blocking the second rail 24 to stop at the extended position E relative to the first rail 22. Thus, the second rail 24 is positioned at the extended position E relative to the first rail 22. Furthermore, the third rail 26 can move further along the opening direction D1 relative to the second rail 24 in the extended position E, thereby preventing the first section 52a of the engaging member 52 from contacting the longitudinal wall 48 of the third rail 26. As a result, the second section 52b of the engaging member 52 moves in accordance with the elastic force of the second elastic arm 56b, thereby engaging the hook 70 of the engaging member 52 with a predetermined mechanism 28, preventing the second rail 24 from moving from the extended position E relative to the first rail 22 along the storage direction D2. In this way, the slide rail assembly 20 is in the extended state.

[0030] Furthermore, the third rail 26 has a first end 26a and a second end 26b, such as a front end and a rear end. In the process of the third rail 26 being returned to a retracted position R along the retraction direction D2 from a predetermined extended position K, a portion of the third rail 26 (such as the second end 26b) is configured to abut against the first section 52a of the engaging member 52, driving the hook 70 of the engaging member 52 to disengage from a predetermined mechanism 28, thereby allowing the second rail 24 to move from the extended position E along the retraction direction D2 relative to the first rail 22.

[0031] In addition, as shown in Figures 10 and 14, a transverse gap exists between the second rail 24 and the first rail 22. For example, as shown in Figure 10, the second rail 24 (longitudinal wall 42 of the second rail 24) and the first rail 22 (longitudinal wall 34 of the first rail 22) are separated by an ideal first transverse distance T1. Due to mounting tolerances and several unforeseen factors, the first transverse distance T1 between the second rail 24 (longitudinal wall 42 of the second rail 24) and the first rail 22 (longitudinal wall 34 of the first rail 22) may increase to a second transverse distance T2, as shown in Figure 14. However, since both the auxiliary portion 66 of the auxiliary member 54 on the second rail 24 and the block mechanism 30 on the first rail 22 are protruding walls extending along the transverse direction, even if the second rail 24 (longitudinal wall 42 of the second rail 24) and the first rail 22 (longitudinal wall 34 of the first rail 22) are separated from each other by a second transverse distance T2 during the process in which the third rail 26 and the second rail 24 move synchronously along the opening direction D1 relative to the first rail 22, the reliability of the interaction between the block mechanism 30 on the first rail 22 and the auxiliary portion 66 of the auxiliary member 54 on the second rail 24 is not easily affected. The block mechanism 30 still provides an acting force F, which moves the auxiliary member 54 and further drives the synchronization member 50 to switch from the first state S1 to the second state S2, thereby ensuring that the synchronization mechanism between the third rail 26 and the second rail 24 is disabled. Such configurations are shown in Figure 11 and related descriptions, and for the sake of simplification, no further illustrations are provided.

[0032] Accordingly, the slide rail assembly 20 according to an embodiment of the present invention has the following technical features: In the process in which the third rail 26 (e.g., inner rail) and the second rail 24 (e.g., intermediate rail) move synchronously along the opening direction D1 relative to the first rail 22 (e.g., outer rail), the blocking mechanism 30 of the first rail 22 is configured to contact the auxiliary portion 66 of the auxiliary member 54, thereby moving the auxiliary member 54 on the second rail 24 and further driving the synchronous member 50 on the second rail 24 to switch from a first state S1 to a second state S2, thereby ensuring that the operating mechanism 45 of the third rail 26 does not contact the extension section 72 of the synchronous member 50, and that the synchronous mechanism between the third rail 26 and the second rail 24 is disabled. Those skilled in the art will readily observe that numerous modifications and changes to the apparatus and method can be made while retaining the teachings of the present invention. Accordingly, the above disclosure should be construed as being limited only by the boundaries of the appended claims.
