[0005] Patent documents 1 and 2 disclose furniture that can prevent two drawers from being opened simultaneously, and a drawer open position control device that can prevent a drawer from being fully opened when a first drawer is opened. However, it is important to develop various products to meet different market needs. [Means for solving the problem]

[0006] The present invention provides a slide rail mechanism that can be applied to a rack.

[0007] According to an embodiment of the present invention, a slide rail mechanism is applicable to a rack. The slide rail mechanism includes a first holding object, a first slide rail assembly, a second slide rail assembly, and a locking member. The first slide rail assembly includes a first rail and a second rail that is longitudinally movable relative to the first rail. The first rail is configured to be attached to the rack, and the second rail is configured to hold the first held object. The second slide rail assembly is disposed on the first held object. The second slide rail assembly includes a third rail and a fourth rail that is longitudinally movable relative to the third rail. The third rail is configured to be attached to the first held object, and the fourth rail is configured to hold the second held object. The locking member is movably attached to the first held object. The first rail includes an auxiliary portion, and the locking member includes a predetermined portion and a locking portion. When the second rail is in the retracted position relative to the first rail, the auxiliary portion is configured to support the predetermined portion to position the locking member at a first predetermined position so that the locking portion of the locking member is not configured to prevent the fourth rail from moving along the opening direction, allowing the second holding object to move along the opening direction relative to the first holding object. During the process of moving the second rail to the extended position in the opening direction relative to the first rail, the locking member is moved from the first predetermined position to a second predetermined position so that the locking portion of the locking member prevents the fourth rail from moving along the opening direction, limiting the movement distance of the second holding object in the opening direction relative to the first holding object.

[0008] According to another embodiment of the present invention, a slide rail mechanism is applicable to a rack. The slide rail mechanism includes a first holding object, a first slide rail assembly, a second slide rail assembly, and a locking member. The first slide rail assembly includes a first rail and a second rail that is longitudinally movable relative to the first rail. The first rail is configured to be attached to the rack, and the second rail is configured to hold the first holding object. The second slide rail assembly is disposed on the first holding object. The second slide rail assembly includes a third rail and a fourth rail that is longitudinally movable relative to the third rail. The third rail is configured to be attached to the first holding object. The locking member is movably attached to the first holding object. The first rail includes an auxiliary portion, and the locking member includes a predetermined portion and a locking portion. During the process of moving the second slide rail to the extended position along the opening direction relative to the first slide rail, the auxiliary portion does not support the predetermined portion so that the locking member is moved from the first predetermined position to the second predetermined position and the locking portion of the locking member is configured to prevent the fourth slide rail from moving along the opening direction.

[0009] These and other objects of the present invention will no doubt become obvious to those skilled in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings. [Brief explanation of the drawings]

[Figure 13] FIG. 13 is an enlarged view of area A in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0011] As shown in FIG. 1 , according to an embodiment of the present invention, a slide rail mechanism is applicable to a rack 22. The slide rail mechanism includes a first slide rail assembly 24, a second slide rail assembly 26, and a first holding object 28. The first slide rail assembly 24 is configured to support the first holding object 28. For example, the first holding object 28 may be an outer casing. The second slide rail assembly 26 is disposed on the first holding object 28. For example, the second slide rail assembly 26 is disposed inside the first holding object 28 (outer casing), and the second slide rail assembly 26 is configured to support a second holding object 30. Preferably, the first holding object 28 is formed with a predetermined space 32 for accommodating the second holding object 30.

[0012] 2 and 3, the second slide rail assembly 26 and the second holding object 30 are omitted from the drawings. Additionally, the slide rail mechanism further includes a locking member 34 movably attached to the first holding object 28.

[0013] The first slide rail assembly 24 includes a first rail 36 and a second rail 38 that is longitudinally movable relative to the first rail 36. The slide rail assembly 24 preferably further includes a first intermediate rail 40 that is movably mounted between the first rail 36 and the second rail 38. In this embodiment, the X-axis is the longitudinal direction (or the length or movement direction of the slide rail), the Y-axis is the lateral direction (or the lateral direction of the slide rail), and the Z-axis is the vertical direction (or the height direction of the slide rail). The first rail 36 is configured to be mounted to the rack 22, and the second rail 38 is configured to hold the first held object 28. Additionally, the locking member 34 may be a link rod, and the movement direction of the locking member 34 is the height direction of the first held object 28 (e.g., the Z-axis direction).

[0014] The first rail 36 includes a first auxiliary portion 42. Preferably, the first rail 36 further includes a second auxiliary portion 44 (as shown in FIG. 3).

[0015] Preferably, the first slide rail assembly 24 further includes a bracket 46. The first rail 36 is attached to the rack 22 via the bracket 46. The bracket 46 is connected (e.g., fixedly connected) to the first rail 36 and can be considered a part of the first rail 36.

[0016] The first auxiliary portion 42 and the second auxiliary portion 44 are preferably disposed on a bracket 46 on the first rail 36. The bracket 46 has a first end 46a and a second end 46b that are opposite each other, such as a front end and a rear end. The first auxiliary portion 42 and the second auxiliary portion 44 are disposed adjacent to the first end 46a of the bracket 46, although the invention is not limited thereto.

[0017] The first auxiliary portion 42 and the second auxiliary portion 44 are protrusions, and the first auxiliary portion 42 and the second auxiliary portion 44 are preferably spaced apart from each other by a longitudinal distance along the longitudinal direction.

[0018] The first auxiliary portion 42 and the second auxiliary portion 44 preferably have a first guide segment G1 and a second guide segment G2 corresponding to each other. Each of the first guide segment G1 and the second guide segment G2 has an inclined surface or an arcuate surface, but the present invention is not limited thereto.

[0019] The first holding object 28 preferably has multiple walls. In this embodiment, the first holding object 28 has a predetermined wall 48 (or side wall). The predetermined wall 48 has a first side L1 and a second side L2 that are opposite each other, such as an outer side and an inner side, but the present invention is not limited thereto.

[0020] Preferably, the first side L1 of the predetermined wall 48 is connected to the second rail 38, and the predetermined space 32 is formed adjacent the second side L2.

[0021] The locking member 34 preferably includes a predetermined portion 50 and a locking portion 52 .

[0022] The locking member 34 is preferably movably attached to the second side L2 of the predetermined wall 48 of the first holding object 28. The extension section 50a of the predetermined portion 50 of the locking member 34 is configured to extend through the predetermined wall 48 to the first side L1 (as shown in FIG. 2).

[0023] Preferably, the predetermined wall 48 is formed with a limiting structure 54, such as an oval hole (as shown in FIG. 2), although the invention is not limited thereto. The extension section 50a of the predetermined portion 50 is inserted into the limiting structure 54 of the predetermined wall 48 so that the locking member 34 can move relative to the first holding object 28 within a limited range.

[0024] 4, the second slide rail assembly 26 includes a third rail 56 and a fourth rail 58 that is longitudinally movable relative to the third rail 56. The third rail 56 is configured to be attached to the second side L2 of the predetermined wall 48 of the first held object 28, and the fourth rail 58 is configured to hold the second held object 30.

[0025] The third rail 56 preferably has a first side L1' and a second side L2' that are opposite each other, such as an outer side and an inner side, but the present invention is not limited thereto. The first side L1' of the third rail 56 is connected to the second side L2 of the first holding object 28, and the second side L2' of the third rail 56 is adjacent to the fourth rail 58. The third rail 56 has an auxiliary space 60 (such as a through-hole) that communicates between the first side L1' and the second side L2' of the third rail 56. The auxiliary space 60 is configured to allow the locking portion 52 of the locking member 34 to pass through the third rail 56 from the first side L1' to the second side L2' of the third rail 56.

[0026] The second slide rail assembly 26 further includes a second intermediate rail 62 movably mounted between the third rail 56 and the fourth rail 58, the second intermediate rail 62 having a blocking portion 64 configured to interact with the locking portion 52 of the locking member 34. In this embodiment, the blocking portion 64 is a protrusion, although the invention is not limited thereto.

[0027] 5 and 6, a plurality of second slide rail assemblies 26 are attached to the first holding object 28. The second slide rail assemblies 26 have substantially the same structural configuration. The fourth rail 58 of each second slide rail assembly 26 is configured to hold a respective second holding object 30. In addition, the locking portion 52 of the locking member 34 penetrates the auxiliary space 60 of the third rail 56 so as to be adjacent to the fourth rail 58 (and the second intermediate rail 62).

[0028] When the second rail 38 is positioned in the retracted position R relative to the first rail 36, the first auxiliary portion 42 is configured to support the predetermined portion 50 (extension section 50a of the predetermined portion 50) so that the locking member 34 is positioned in the first predetermined position K1.

[0029] When the locking member 34 is located in the first predetermined position K1, the locking portion 52 of the locking member 34 is preferably not aligned with the blocking portion 64 of the second intermediate rail 62 along the longitudinal direction. For example, the vertical position of the locking portion 52 of the locking member 34 along the vertical direction does not correspond to the vertical position of the blocking portion 64 of the second intermediate rail 62 along the vertical direction (the lateral position of the locking portion 52 of the locking member 34 along the lateral direction corresponds to the lateral position of the blocking portion 64 of the second intermediate rail 62 along the lateral direction).

[0030] When the second rail 38 is in the retracted position R relative to the first rail 36 and the fourth rail 58 and second intermediate rail 62 are retracted relative to the third rail 56, the locking portion 52 of the locking member 34 and the blocking portion 64 of the second intermediate rail 62 are spaced apart from each other along the longitudinal direction by a predetermined longitudinal distance M (as shown in FIG. 5).

[0031] 5, 7, 8, and 9, during the process of moving the second rail 38 from the retracted position R to the extended position E along the opening direction D1 relative to the first rail 36 (as shown in FIG. 9), the first auxiliary portion 42 no longer supports the predetermined portion 50 to allow the locking member 34 to move from the first predetermined position K1 (as shown in FIG. 5) to the second predetermined position K2 (as shown in FIGS. 7 and 8) along the predetermined height direction H. Thus, the locking portion 52 of the locking member 34 is configured to prevent the fourth rail 58 from moving along the opening direction D1 to limit the distance that the second holding object 30 moves along the opening direction D1 relative to the first holding object 28.

[0032] In this embodiment, the locking portion 52 of the locking member 34 is configured to block the movement path of the block portion 64 of the second intermediate rail 62 along the opening direction D1 to prevent the fourth rail 58 from moving along the opening direction D1. Specifically, when the locking member 34 is located at the second predetermined position K2, the locking portion 52 of the locking member 34 is aligned with the block portion 64 of the second intermediate rail 62 along the longitudinal direction. As a result, the second intermediate rail 62 is configured to indirectly prevent the fourth rail 58 from moving along the opening direction D1 (e.g., a synchronization mechanism is provided between the second intermediate rail 62 and the fourth rail 58) to limit the movement distance of the second holding object 30 relative to the first holding object 28 along the opening direction D1. Furthermore, in an alternative embodiment, the second slide rail assembly 26 includes only the third rail 56 and the fourth rail 58 (i.e., the second slide rail assembly 26 does not include the second intermediate rail 62), and the fourth rail 58 is configured to hold the second held object 30 and has a blocking portion. When the locking member 34 is located at the second predetermined position K2, the locking portion 52 of the locking member 34 is aligned with the blocking portion of the fourth rail 58 along the longitudinal direction (the vertical position of the locking portion 52 of the locking member 34 along the vertical direction corresponds to the vertical position of the blocking portion of the fourth rail 58 along the vertical direction, and the lateral position of the locking portion 52 of the locking member 34 along the lateral direction corresponds to the lateral position of the blocking portion of the fourth rail 58 along the lateral direction), and the locking member 34 is configured to directly block the movement path of the fourth rail 58 along the opening direction D1 to limit the movement distance of the second held object 30 along the opening direction D1 relative to the first held object 28.

[0033] During the process of moving the second rail 38 from the retracted position R to the extended position E along the opening direction D1 relative to the first rail 36 (as shown in FIG. 9), the second guide section G2 of the second auxiliary part 44 is configured to contact and guide the predetermined part 50 (the extension section 50a of the predetermined part 50) of the locking member 34 to move the locking member 34 from the first predetermined position K1 (as shown in FIG. 5) to the second predetermined position K2 (as shown in FIGS. 7 and 8). Meanwhile, the locking member 34 can also descend to the second predetermined position K2 due to gravity.

[0034] 9, 10, and 11, when the second rail 38 is in the extended position E relative to the first rail 36 (as shown in FIG. 9) and the locking member 34 is in the second predetermined position K2, the locking portion 52 of the locking member 34 and the blocking portion 64 of the second intermediate rail 62 are aligned along the longitudinal direction and block each other (as shown in FIGS. 10 and 11), thereby indirectly preventing the fourth rail 58 from moving along the opening direction D1 and limiting the movement distance of the second holding object 30 along the opening direction D1 relative to the first holding object 28. In this embodiment, the second holding object 30 can be moved along the opening direction D1 from a predetermined retracted position R' (as shown in FIG. 9) relative to the first holding object 28, and can be extended a predetermined extension distance Q relative to the first holding object 28 (as shown in FIG. 10). Or, in other embodiments, the second holding object 30 is configured to be prevented from moving along the opening direction D1 from a predetermined retracted position R' relative to the first holding object 28. That is, the second holding object 30 cannot be fully opened relative to the first holding object 28.

[0035] Furthermore, during the process of moving the second rail 38 relative to the first rail 36 along the retraction direction D2 from the extended position E' (shown in Figures 9 and 10) to the retracted position R (shown in Figures 5 and 6), the first guide section G1 of the first auxiliary portion 42 is configured to contact and guide the predetermined portion 50 (the extended section 50a of the predetermined portion 50) of the locking member 34 in order to move the locking member 34 from the second predetermined position K2 (shown in Figures 9 and 10) to the first predetermined position K1 (shown in Figures 5 and 6).

[0036] 12 and 13, when the second rail 38 is in the retracted position R relative to the first rail 36, the first auxiliary portion 42 is configured to support the predetermined portion 50 so that the locking member 34 is positioned in the first predetermined position K1 so that the locking portion 52 of the locking member 34 is not longitudinally aligned with the locking portion 64 of the second intermediate rail 62. Thus, the locking portion 52 of the locking member 34 is not configured to prevent the fourth rail 58 from moving along the opening direction D1 so that the second holding object 30 can move along the opening direction D1 from the predetermined retracted position R' (shown in FIG. 9) relative to the first holding object 28 to a predetermined extended position E' (shown in FIG. 12), such as the fully extended position E' (shown in FIG. 12).

[0037] Therefore, the slide rail mechanism according to the embodiment of the present invention has the following technical features.

[0038] 1) The slide rail mechanism is applicable to the rack, and the locking member 34 is movably attached to the first holding object 28.

[0039] 2) When the second rail 38 is in the extended position E relative to the first rail 36 and the locking member 34 is in the second predetermined position K2, the locking portion 52 of the locking member 34 is configured to prevent the fourth rail 58 from moving along the opening direction D1, thereby limiting the movement distance of the second holding object 30 along the opening direction D1 relative to the first holding object 28. For example, the second holding object 30 is configured to be prevented from moving from a predetermined retracted position R' (shown in FIG. 9 ) along the opening direction D1 relative to the first holding object 28. Alternatively, the second holding object 30 is movable from a predetermined retracted position R' along the opening direction D1 relative to the first holding object 28, but can be extended a predetermined extension distance Q without being fully opened relative to the first holding object 28 (as shown in FIG. 10 ). For example, the second holding object 30 cannot be moved relative to the first holding object 28 along the opening direction D1 from a predetermined retracted position R' to a fully extended position E' (shown in Figure 12).

[0040] 3) When the second rail 38 is in the retracted position R relative to the first rail 36 and the locking member 34 is in the first predetermined position K1, the locking portion 52 of the locking member 34 is not configured to block movement of the fourth rail 58 along the opening direction D1 so as to allow the second holding object 30 to be moved along the opening direction D1 relative to the first holding object 28 from the predetermined retracted position R' to the fully extended position E' (shown in FIG. 12).

[0041] Those skilled in the art will readily recognize that numerous modifications and variations can be made to the apparatus and method while retaining the teachings of the present invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
