As shown in fig. 4 and 5, the slide rail assembly 24 includes a first rail 36, a second rail 38, and a third rail 40.

The first rail 36 includes a first region 42 and a second region 44, and preferably the first region 42 and the second region 44 are located at different positions on the same side of the first rail 36. For example, the first rail 36 has a first side 45a and a second side 45b opposite to the first side 45a, and the first region 42 and the second region 44 are located on the first side 45 a. Wherein the first region 42 and the second region 44 have a first channel 46 (or first longitudinal channel) and a second channel 48 (or second longitudinal channel), respectively.

Specifically, the first rail 36 includes a longitudinal wall 50, a first upper wall 52a, a first lower wall 52b, a second upper wall 54a, and a second lower wall 54b. The first upper wall 52a and the first lower wall 52b connect the longitudinal wall 50, and the longitudinal wall 50, the first upper wall 52a and the first lower wall 52b together define the first channel 46. Preferably, the first upper wall 52a and the first lower wall 52b of the first rail 36 respectively comprise a first wall section W1 and a second wall section W2 connected to the first wall section W1 substantially vertically; on the other hand, the second upper wall 54a and the second lower wall 54b connect the longitudinal wall 50, and the longitudinal wall 50, the second upper wall 54a and the second lower wall 54b together define the second channel 48. Preferably, the second upper wall 54a and the second lower wall 54b of the first rail 36 respectively include a third wall section W3 and a fourth wall section W4 connected to the third wall section W3 substantially perpendicularly. Preferably, the first rail 36 includes a first feature 56, and preferably, a second feature 58.

Here, the first feature 56 and the second feature 58 are both exemplified by a protrusion, but are not limited in implementation.

The second rail 38 is movably mounted in the first region 42 and is displaceable relative to the first rail 36. For example, the second rail 38 can be displaced relative to the first rail 36 through the first channel 46. Preferably, the second rail 38 includes an upper rail section 55a, a lower rail section 55b, and an intermediate section 55c connected between the upper rail section 55a and the lower rail section 55 b. Preferably, a first bending section 55d is provided between the upper rail section 55a and the middle section 55c, and a second bending section 55e is provided between the lower rail section 55b and the middle section 55 c. Wherein the upper rail section 55a and the lower rail section 55b are positioned within the first channel 46 of the first rail 36 to abut between the first upper wall 52a and the first lower wall 52b of the first rail 36, thus facilitating the supporting strength of the second rail 38 and the first rail 36 with respect to each other.

The third rail 40 is located in the second region 44 and is displaceable relative to the first rail 36. For example, the third rail 40 can be displaced relative to the first rail 36 through the second channel 48. Preferably, the third rail 40 includes an upper rail section 57a, a lower rail section 57b, and an intermediate section 57c connected between the upper rail section 57a and the lower rail section 57 b.

Wherein the upper rail section 57a and the lower rail section 57b are positioned in the second channel 48 of the first rail 36 to be abutted between the second upper wall 54a and the second lower wall 54b of the first rail 36, thus contributing to the supporting strength of the third rail 40 and the first rail 36 with respect to each other.

The first bracket 28 is positioned adjacent a front portion 60 of the first rail 36. The first bracket 28 may be an additional fitting mounted to the front 60 of the longitudinal wall 50 adjacent the first rail 36; alternatively, as in the present embodiment, the first bracket 28 may be integrally formed at the front 60 of the longitudinal wall 50 adjacent the first rail 36, and thus, the first bracket 28 and the first rail 36 may be considered to be the same component. Further, the first bracket 28 has at least one mounting feature 62. Wherein the at least one mounting feature 62 of the first bracket 28 is exemplified herein by a plurality of attachment holes.

As shown in fig. 4 and 6, the second bracket 30 is movably mounted adjacent a rear portion 64 of the first rail 36. In other words, the second bracket 30 and the first bracket 28 can be used as a rear bracket and a front bracket of the first rail 36, respectively. Specifically, the second bracket 30 includes an extension wall 66 and an end wall 68 substantially perpendicularly connecting the extension wall 66. Preferably, the second bracket 30 further comprises a first wall 70a and a second wall 70b, and the extension wall 66 is connected between the first wall 70a and the second wall 70 b. Wherein the first wall 70a, the second wall 70b and the extension wall 66 together define a space 72 for providing the first rail 36 to movably mount such that the second bracket 30 and the first rail 36 (or the first bracket 28) can move relative to each other.

Preferably, the second bracket 30 is displaceable within a limited range relative to the first rail 36 via a stop structure 74. For example, the limiting structure 74 includes a slot 76 and at least one connecting member 78 (e.g., two connecting members 78). Here, the second bracket 30 has the long hole 76 as an example, and the at least one connecting member 78 has a head 80a and a body 80b connected to the head 80a. The head 80a has a size greater than the body 80 b. The head 80a is located at one side of the second bracket 30, and the body 80b is disposed through a portion of the elongated hole 76 for connecting the second bracket 30 to the first rail 36 such that the second bracket 30 and the first rail 36 can be displaced within a limited range relative to each other. The second bracket 30 has at least one mounting feature 82 located on the end wall 68, wherein the at least one mounting feature 82 of the second bracket 30 is exemplified herein by a plurality of attachment holes. Preferably, a wall repair member 83 is disposed on the extension wall 66 of the second bracket 30, and the wall repair member 83 helps to strengthen the structural strength of the second bracket 30. The wall repairing member 83 may be connected to the second bracket 30 by riveting, welding or screwing.

Preferably, the second rail 38 and/or the third rail 40 has a smaller rail length than the first rail 36. This may be in response to the requirements of the second rail 38 and the third rail 40 to carry the first carrier 20 and the second carrier 22. For example, the second rail 38 and the third rail 40 can be adapted for shorter length carriers. Of course, the sliding track length of the second track 38 and/or the third track 40 may be substantially the same as the sliding track length of the first track 36, such that the second track 38 and the third track 40 may be suitable for long-length carriers, and thus, the sliding track length of the second track 38 and/or the third track 40 is not limited in implementation.

Preferably, the sliding rail assembly 24 further includes at least one elastic member, here, a first elastic member 84 and a second elastic member 86 are exemplified. The first elastic member 84 and the second elastic member 86 are disposed on the second rail 38 and the third rail 40, respectively. The first elastic member 84 includes a first connecting portion 88, a first elastic portion 90 connected to the first connecting portion 88 and tilted at an angle with respect to the first connecting portion 88, and a first blocking section 92 located on the first elastic portion 90; similarly, the second elastic member 86 includes a second connecting portion 94, a second elastic portion 96 connected to the second connecting portion 94 and tilted at an angle with respect to the second connecting portion 94, and a second stop 98 located at the second elastic portion 96. Wherein the first blocking section 92 and/or the second blocking section 98 may be a protruding structure; alternatively, in other embodiments, the first stop 92 and/or the second stop 98 may be a recessed feature or a hole.

As shown in fig. 6, when the second rail 38 and/or the third rail 40 are respectively displaced from a retracted position to an extended position E relative to the first rail 36, the second rail 38 and/or the third rail 40 can be snapped or blocked on the first feature 56 and/or the second feature 58 of the first rail 36 by the first elastic member 84 and/or the second elastic member 86, respectively, so as to provide the second rail 38 and/or the third rail 40 temporarily located at the extended position E relative to the first rail 36. As shown in fig. 7, in the extended position E, the second rail 38 can be snapped or blocked against the first feature 56 of the first rail 36 by the first stop 92 of the first resilient member 84. It should be noted that when a force is applied to the first resilient portion 90 and/or the second resilient portion 96 by a user, the first stop 92 and/or the second stop 98 may be moved away from the first feature 56 and/or the second feature 58, such that the second rail 38 and/or the third rail 40 may be operatively moved away from the extended position E relative to the first rail 36, such as being removed from the first rail 36.

As shown in fig. 4 and 8, the second rail 38 and/or the third rail 40 includes a plurality of mounting holes spaced apart from each other, such as a first mounting hole 102 and a second mounting hole 104. Here, taking the example that the mounting holes 102 and 104 each include a first hole 106a and a second hole 106b, the first hole 106a communicates with the second hole 106b, and the size of the first hole 106a is larger than the size of the second hole 106 b. Wherein the mounting holes 102, 104 of the second rail 38 may provide a plurality of mounting members 108 (standoff) mounting of the first carrier 20. Preferably, the slide rail assembly further comprises a first elastic stopper 110 and/or a second elastic stopper 112 for blocking the first hole portion 106a of one of the mounting holes of the adjacent second rail 38 and/or third rail 40, respectively. For example, the mounting member 108 of the first carrier 20 can push the first elastic blocking member 110 from the first hole portion 106a of the first mounting hole 102 of the second rail 38 to enter the second hole portion 106b, and then the first elastic blocking member 110 is restored, and the first elastic blocking member 110 is blocked at the first hole portion 106a of the adjacent second rail 38, so as to provide the first carrier 20 that cannot be arbitrarily displaced relative to the second rail 38. Similarly, the mounting holes 102, 104 of the third rail 40 can provide a plurality of mounting devices for the second carrier 22, and for brevity, reference should be made to the configuration relationship between the second rail 38 and the first carrier 20 (fig. 8), which is not repeated herein.

As shown in fig. 9, the first carrier 20 and the second carrier 22 may be mounted to the post of the frame 26 via the slide rail assembly 24, such as the at least one mounting feature 62 of the first bracket 28 for at least one first fastener 114 to mount the first bracket 28 to the first post 32 of the frame 26. Because the first rail 36 is directly formed with the first channel 46 and the second channel 48 on the same side, the second rail 38 and the third rail 40 can be mounted corresponding to the first channel 46 and the second channel 48 to shorten the distance between the second rail 38 and the third rail 40. According to this feature, when the first carrier 20 and the second carrier 22 are mounted on the second rail 38 and the third rail 40, respectively, the first carrier 20 and the second carrier 22 can be designed to be almost close to each other, so as to facilitate the spatial utilization.

From the above description, it can be seen that the enhancement effect and advantage of the present invention are:

1. the first rail can simultaneously provide two sliding rails (for example, the second rail and the third rail are installed), so that the manufacturing cost of the sliding rail assembly can be reduced.

2. The second rail and/or the third rail can be temporarily positioned in an extended position relative to the first rail to facilitate maintenance operations of the track assembly or the carrier.

3. The first rail and the second rail and the first rail and the third rail are provided with supporting structures which can be abutted against each other, so that the supporting strength between the first rail and the second rail is facilitated.

While the invention has been described with reference to the present specific embodiments, it will be appreciated by those skilled in the art that the above embodiments are for illustration only, and that various equivalent changes and modifications may be made without departing from the spirit of the invention, and therefore, all changes and modifications to the above embodiments are intended to be within the scope of the claims of the present application as long as they come within the true spirit of the invention.
