The rail 22 includes an upper wall 36a, a lower wall 36b and a longitudinal wall 38 connected between the upper wall 36a and the lower wall 36 b. Preferably, the longitudinal wall 38 of the rail member 22 is arranged with a relief space 37 adjacent to an end of the rail member 22, and the relief space 37 is, for example, but not limited to, a hole or a groove. On the other hand, the reinforcement 30 is connected (e.g., fixed) to the longitudinal wall 38 of the rail member 22 to be regarded as a part of the rail member 22, and the reinforcement 30 is away from the release space 37. The reinforcement member 30 has a plurality of walls defining a reinforcement channel 40. The second bracket 34 is mounted to one of the reinforcement 30 and the rail 22.

The support 24 includes an upper support portion 48a, a lower support portion 48b and a longitudinal portion 50 connected between the upper support portion 48a and the lower support portion 48 b. Preferably, the auxiliary member 32 is connected to the support member 24. Herein, the auxiliary element 32 is fixed to the supporting element 24, and the auxiliary element 32 can be regarded as a part of the supporting element 24. In other embodiments, the auxiliary element 32 may be integral to the support element 24.

The first bracket 26 and the support member 24 are longitudinally displaceable relative to each other. Here, the first bracket 26 is movably mounted to the auxiliary element 32, but the embodiment is not limited thereto. Alternatively, the fastener 28 is movable relative to the first bracket 26.

As shown in fig. 3 and 4, the auxiliary element 32 is fixed to the supporting element 24 through at least one fixing portion 60. In addition, the auxiliary element 32 is arranged with a stop feature 62 (e.g., a bounded longitudinal hole or slot, but not limited in implementation), and the first bracket 26 is arranged with a connecting member 64 extending through a portion of the stop feature 62 to allow the first bracket 26 and the auxiliary element 32 to move relative to each other.

On the other hand, the auxiliary element 32 is arranged with a first driving portion 72 and a second driving portion 74. The first driving portion 72 and the second driving portion 74 can be integrated into a fitting 71, and the fitting 71 is, for example, fixed to the auxiliary 32 and can be regarded as a part of the auxiliary 32; alternatively, in other embodiments, the first driving portion 72 and the second driving portion 74 can be directly integrated with the auxiliary element 32, and therefore, the implementation is not limited.

The corresponding feature 93 includes an inclined surface or an arcuate surface, and the corresponding feature 93 is configured to cooperate with the support feature 85 of the first bracket 26.

As shown in FIG. 8, the longitudinal wall 38 of the rail member 22 has a first side L1 opposite the first side L1 from a second side L2. The reinforcing member 30 is connected to the first side L1 of the rail member 22, and preferably, the slide rail mechanism 20 further includes a first movable rail 94 and a second movable rail 96 arranged to the second side L2 of the rail member 22. The rail member 22, the first movable rail 94 and the second movable rail 96 are telescopically connected to each other to form a so-called three-section slide rail.

Preferably, the reinforcing member 30 includes an upper side wall 98a, a lower side wall 98b and an extension wall 100 connected between the upper side wall 98a and the lower side wall 98b, and the reinforcing member 30 is connected to the first side L1 of the rail member 22 through the extension wall 100. The upper and

lower walls

98a, 98b of the reinforcement member 30 and the extension wall 100 together define the reinforcement channel 40.

The lower support portion 48b of the support member 24 covers a portion of the lower wall 36b of the rail member 22. Preferably, the lower support portion 48b of the support member 24 has a first section K1 and a second section K2; the first section K1 is used to support the lower wall 36b of the rail 22, the second section K2 is bent relative to the first section K1, and the second section K2 extends to a side adjacent to the lower wall 36b of the rail 22.

The upper support portion 48a of the support member 24 covers a portion of the upper wall 36a of the rail member 22. Preferably, the upper supporting portion 48a of the supporting member 24 has a third section K3 and a fourth section K4; the third section K3 is used to support the upper wall 36a of the rail 22, the fourth section K4 is bent relative to the third section K3, and the fourth section K4 extends to a side adjacent to the upper wall 36a of the rail 22.

Preferably, the longitudinal portion 50 and the lower support portion 48B of the supporting member 24 are connected to each other through at least one first bending portion B1, and the longitudinal portion 50 and the upper support portion 48a of the supporting member 24 are connected to each other through at least one second bending portion B2.

Preferably, the longitudinal portion 50, the at least one first bent portion B1 and the at least one second bent portion B2 of the supporting member 24 together define a space 101, and the position of the reinforcing member 30 corresponds to the space 101.

Preferably, one of the at least one first bending part B1 and the at least one second bending part B2 of the supporting member 24 is used for supporting the first side L1 of the longitudinal wall 38 of the rail member 22.

As shown in fig. 9 and 10, the fastener 28 can be in one of a first state S1 (e.g., an unlocked state) and a second state S2 (e.g., a locked state) relative to the first bracket 26. When the fastening member 28 is in the first state S1 (as shown in fig. 9), the fastening portion 67 of the fastening member 28 is away from the at least one first mounting member 56 of the first bracket 26; when the fastening member 28 is in the second state S2 (shown in fig. 10), the fastening portion 67 of the fastening member 28 is adjacent to the at least one first mounting member 56 of the first bracket 26.

Preferably, one of the first contact portion 68 of the fastener 28 and the first driving portion 72 of the auxiliary element 32 includes a first guiding feature (e.g., a ramp and an arc). On the other hand, one of the second contact portion 70 of the fastener 28 and the second driving portion 74 of the auxiliary element 32 includes a second guiding feature (e.g., a slope and a curved surface).

When the supporting member 24 is displaced from a first position P1 (shown in fig. 9) to a second position P2 (shown in fig. 10) in a first direction D1 relative to the first bracket 26, the supporting member 24 contacts the first contact portion 68 of the fastening member 28 through the first driving portion 72 of the auxiliary member 32, so that the supporting member 24 drives the fastening member 28 to transition from the first state S1 (shown in fig. 9) to the second state S2 (shown in fig. 10).

Conversely, when the supporting element 24 is shifted from the second position P2 (shown in fig. 10) to the first position P1 along a second direction D2 opposite to the first direction D1 relative to the first bracket 26, the supporting element 24 contacts the second contact portion 70 of the fastener 28 through the second driving portion 74 of the auxiliary element 32, so that the supporting element 24 brings the fastener 28 to return from the second state S2 (shown in fig. 10) to the first state S1 (shown in fig. 9).

As shown in fig. 11, the supporting member 24 is in the first position P1 relative to the first bracket 26. Wherein the first structure 76 of the first lock 80 is a predetermined distance from the second structure 78 of the first bracket 26; preferably, the third resilient segment 90 and the second resilient segment 88 are close to each other, wherein the third structure 82 of the second resilient segment 88 has a predetermined distance from the fourth structure 84 of the first bracket 26. Preferably, the third structure 82 of the second resilient segment 88 has a guiding surface 102, and the guiding surface 102 is, for example, a slope or a cambered surface. Preferably, the release feature 92 of the third resilient segment 90 corresponds to the release space 37 of the rail member 22, and the corresponding feature 93 of the third resilient segment 90 is a predetermined distance from the support feature 85 of the first bracket 26.

As shown in fig. 11 and 12, the supporting member 24 can be displaced from the first position P1 (shown in fig. 11) to the first direction D1 to the second position P2 (shown in fig. 12) relative to the first bracket 26.

Wherein the supporting member 24 can be maintained at the second position P2 by the cooperation of the first structure 76 and the second structure 78. For example, the first structure 76 of the first lock 80 can be snapped into the second structure 78 of the first bracket 26, such that the support member 24 has a first locking mechanism when in the second position P2 relative to the first bracket 26.

Preferably, the support member 24 is maintained in the second position P2 by the cooperation of the third structure 82 and the fourth structure 84. For example, when the supporting member 24 is displaced from the first position P1 to the second position P2 in the first direction D1, the corresponding feature 93 of the third resilient segment 90 contacts the supporting feature 85 of the first bracket 26 to generate a force F (as shown in fig. 12), such that the third resilient segment 90 swings at an angle in response to the force F, and the release feature 92 of the third resilient segment 90 is no longer supported by the wall of the longitudinal wall 38 of the rail 22 corresponding to the release space 37 of the rail 22, and at this time, the third resilient segment 90 can accumulate a return resilient force, the third resilient segment 90 is no longer close to the second resilient segment 88, and the third structure 82 of the second resilient segment 88 can be locked to the fourth structure 84 of the first bracket 26, such that the supporting member 24 has a second locking mechanism when located at the second position P2 relative to the first bracket 26.

It should be noted that when the first structure 76 of the first lock 80 is released from the second structure 78 of the first bracket 26 and the third structure 82 of the second lock 86 is released from the fourth structure 84 of the first bracket 26, the support member 24 can be returned to the first position P1 (fig. 11) from the second position P2 (fig. 12) relative to the first bracket 26. For example, as shown in fig. 12, the rail 22 can be displaced in the first direction D1 relative to the supporting member 24 at the second position P2, such that the releasing feature 92 of the third resilient segment 90 corresponds to the releasing space 37 of the rail 22 again, the third resilient segment 90 releases the return resilient force to close the second resilient segment 88 again, and the third structure 82 of the second resilient segment 88 is released from the fourth structure 84 of the first bracket 26. On the other hand, through the guiding portion 77 of the first structure 76, the first structure 76 on the first elastic section 81 of the first locking element 80 can be released from the second structure 78 of the first bracket 26 when the supporting element 24 returns to the first position P1 from the second position P2 relative to the first bracket 26; alternatively, in other modes of operation, the latching relationship of the first structure 76 to the second structure 78, and the latching relationship of the third structure 82 to the fourth structure 84 may be manually operated to release the latching relationships.

As shown in fig. 13 and 14, the slide mechanism can be mounted to a first post 104a of a frame through at least a first mounting member 56 of the first bracket 26. The supporting member 24 can be displaced from the first position P1 (shown in fig. 13) to the first direction D1 to the second position P2 (shown in fig. 14) relative to the first bracket 26, and the supporting member 24 can bring the fastening member 28 from the first state S1 (shown in fig. 13) to the second state S2 (shown in fig. 14), so that the fastening portion 67 of the fastening member 28 can fasten the first pillar 104 a. Since the operation principle and the description of the supporting element 24 for driving the fastening element 28 to transition from the first state S1 to the second state S2 are disclosed above (fig. 9 and 10), for the sake of brevity, no further description is provided herein.

As shown in fig. 14, the first structure 76 is engaged with the second structure 78 (first locking mechanism) and the third structure 82 is engaged with the fourth structure 84 (second locking mechanism), so that the supporting member 24 is maintained at the second position P2 (this portion can also be matched with fig. 10 and 12) relative to the first bracket 26, thereby improving the reliability of the fastener 28 in the second state S2 (e.g., locked state). According to this configuration, the fastening portion 67 of the fastener 28 can be fastened to the first pillar 104a of the rack for safety when applied to the rack.

As shown in fig. 15, once the at least one first mounting member 56 of the first bracket 26 of the slide mechanism 20 is mounted to the first post 104a of the rack, and the fastener 28 in the second state S2 is fastened to the first post 104a, the slide mechanism 20 can be further mounted to a second post 104b of the rack through the at least one second mounting member 58 of the second bracket 34.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

1. the support member 24 covers a portion of the rail member 22 to reinforce the structural strength of the first bracket 26 and the rail member 22 to each other.

2. Since the support member 24 can be adjusted to be longitudinally displaced on the rail member 22, the first bracket 26 can be displaced through the support member 24 with a longer stroke.

3. The first bracket 26 is formed as a two-part bracket by the support member 24 to be displaceable on the rail member 22, thereby being more suitable for a rack of a specific depth than the conventional three-part bracket.

4. The first structure 76 and the second structure 78 are configured to cooperate (first locking mechanism) or the third structure 82 and the fourth structure 84 are configured to cooperate (second locking mechanism) to facilitate the reliability of the fastener 28 in the second state S2 (e.g., locked state) when the supporting member 24 is at the second position P2 relative to the first bracket 26.

5. When the support member 24 is at the first predetermined position X1, the first bracket 26 and the second bracket 34 define a first length therebetween (as shown in fig. 1); when the supporting member 24 is at the second predetermined position X2, the first bracket 26 and the second bracket 34 define a second length (as shown in fig. 2) between each other that is longer than the first length. Thus, the slide rail mechanism 20 can be adapted to different distances between the two columns of the rack.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
