In addition, in order to increase the structural strength of the third rail, both the top and the bottom of the third rail of this patent are folded joint surfaces (a structure in which two folds are overlapped), and in order to correspond to the folded joint surface of the third rail, the transverse width of the concave structure of the second rail must exceed the transverse width of the channel of the first rail, so the folded joint surface of the third rail cannot correspond to the transverse width of the channel of the first rail, in this case, the overall transverse width of the slide rail assembly is often increased, which is not favorable for a server with a wider installation width of the slide rail assembly.

Detailed Description
As shown in fig. 1 and 2, the slide rail assembly 20 of the first embodiment of the present invention includes a first rail 22, a first bracket 24, and a second rail 26, and preferably further includes a third rail 28 and a second bracket 29.
The first rail 22 includes a first wall 30a, a second wall 30b and a longitudinal wall 32 connected between the first wall 30a and the second wall 30b of the first rail 22. The first wall 30a, the second wall 30b and the longitudinal wall 32 of the first rail 22 together define a first channel 33 for movably mounting the second rail 26. The first rail 22 has a first end E1 and a second end E2 away from the first end E1 of the first rail 22. The first end E1 and the second end E2 are, for example, a front end and a rear end of the first rail 22, respectively, but are not limited thereto.
The first bracket 24 is disposed on the first rail 22. Preferably, the first bracket 24 is located adjacent the first end E1 of the first rail 22.
The second rail 26 is longitudinally displaceable relative to the first rail 22. The second rail 26 includes a first wall 34a, a second wall 34b and a longitudinal wall 36 connected between the first wall 34a and the second wall 34b of the second rail 26. The first wall 34a, the second wall 34b and the longitudinal wall 36 of the second rail 26 together define a second channel 37 for movably mounting the third rail 28.
The third rail 28 is longitudinally displaceable relative to the second rail 26. The third rail 28 includes a first wall 38a, a second wall 38b and a longitudinal wall 40 connected between the first wall 38a and the second wall 38b of the third rail 28.
The second bracket 29 is disposed adjacent to the second end E2 of the first rail 22.
One of the first rail 22 and the first bracket 24 is provided with a first supporting portion 42 and a second supporting portion 44. Herein, the first supporting portion 42 and the second supporting portion 44 are disposed on the first bracket 24, and the first supporting portion 42 and the second supporting portion 44 are integrated on the first bracket 24, but the implementation is not limited thereto.
Preferably, the first bracket 24 includes a side wall 46 and at least one first mounting member 48 adjacent the side wall 46. In another aspect, the second bracket 29 includes a side plate 50 and at least one second mount 52 adjacent the side plate 50.
As shown in fig. 3 and 4, the at least one first mounting member 48 of the first bracket 24 is configured to provide mounting of the first rail 22 to a first post 54a of a rack (or cabinet), and the at least one second mounting member 52 of the second bracket 29 is configured to provide mounting of the first rail 22 to a second post 54b of the rack. Preferably, a fastener 55 is movably mounted on the first bracket 24, and the fastener 55 is used for fastening the first pillar 54 a.
Further, when the second rail 26 is at a retracted position P1 relative to the first rail 22, the first supporting portion 42 and the first wall 34a of the second rail 26 cannot support each other, and the second supporting portion 44 and the second wall 34b of the second rail 26 cannot support each other.
As shown in fig. 5, 6 and 7, when the second rail 26 is longitudinally displaced from the retracted position P1 to an extended position P2 in an opening direction relative to the first rail 22, the first supporting portion 42 and the first wall 34a of the second rail 26 are provided for supporting each other, preferably, the second supporting portion 44 and the second wall 34b of the second rail 26 are provided for supporting each other, and the side wall 46 of the first bracket 24 and the longitudinal wall 36 of the second rail 26 are provided for supporting each other.
Preferably, the first wall 30a and the second wall 30b of the first rail 22 each include a first wall segment X1 and a second wall segment X2 bent with respect to the first wall segment X1. Each second wall segment X2 of the first rail 22 has a transverse width T (shown in fig. 7) with the longitudinal wall 32 of the first rail 22. On the other hand, the first wall 38a and the second wall 38b of the third rail 28 each include a first wall section K1 bent laterally with respect to the longitudinal wall 40 of the third rail 28, and a second wall section K2 connected substantially perpendicularly with respect to the first wall section K1 of the third rail 28, wherein each second wall section K2 of the third rail 28 extends into the second channel 37 of the second rail 26, and each second wall section K2 of the third rail 28 is correspondingly located within the range of the transverse width T of the first rail 22, and further, the longitudinal wall 40 of the third rail 28 is located in a plane H that extends only slightly beyond a slight distance with respect to each second wall section X2 of the first rail 22. Therefore, it can be seen that the longitudinal wall 40 of the third rail 28 and each of the second wall segments X2 of the first rail 22 are substantially located on the same plane H, and according to these structural features, the overall width of the slide rail assembly can be reduced to achieve a narrower width.
Preferably, the first wall 34a and the second wall 34B of the second rail 26 each include a first extending section M1 bent laterally relative to the longitudinal wall 36 of the second rail 26, a first bent section B1 connected bent relative to the first extending section M1, a second extending section M2 bent laterally relative to the first bent section B1, and a second bent section B2 connected bent relative to the second extending section M2. The first extending section M1, the first bending section B1, the second extending section M2 and the second bending section B2 are in a continuous bending structure, so that the structural strength of the second rail 26 can be enhanced, which is helpful for improving the overall structural strength of the sliding rail assembly. In addition, the second bending section B2 of the second rail 26 and the first wall section K1 of the third rail 28 can provide mutual support to strengthen the support strength between the second rail 26 and the third rail 28.
Preferably, the end of the second wall section K2 of the third rail 28 is adjacent the second extension M2 of the second rail.
Preferably, the longitudinal wall 36 of the second rail 26 includes a first longitudinal section L1, a second longitudinal section L2 and a middle section L3, and the first longitudinal section L1 and the second longitudinal section L2 are respectively bent from two ends of the middle section L3, so that the connection between two ends of the middle section L3 and the first longitudinal section L1 and the second longitudinal section L2 has a structural reinforcement effect.
Preferably, the first support portion 42 includes a first support section 42a for providing support to the first wall 34a of the second rail 26. For example, the first supporting section 42a is used to provide a supporting effect to the first wall 34a of the second rail 26 in a transverse direction (in other words, the first supporting section 42a provides a supporting effect to a side of the first wall 34a of the second rail 26), and cooperates with the side wall 46 of the first bracket 24 to make the first wall 34a of the second rail 26 located between the first supporting section 42a and the side wall 46 of the first bracket 24, so as to prevent the transverse movement of the second rail 26 (for example, the movement of the second rail 26 from the left or right in fig. 7 can be prevented, but the implementation is not limited); preferably, the first supporting portion 42 further comprises another first supporting section 42b for providing a supporting effect to the first wall 34a of the second rail 26 in the vertical direction (e.g. preventing the second rail 26 from moving from the top of fig. 7). Wherein, the transverse direction and the vertical direction are two directions substantially perpendicular to each other.
Similarly, the second support portion 44 includes a second support section 44a for providing support to the second wall 34b of the second rail 26. For example, the second supporting section 44a is used to provide a supporting effect to the second wall 34b of the second rail 26 in a transverse direction (in other words, the second supporting section 44a provides a supporting effect to a side of the second wall 34b of the second rail 26), and cooperates with the side wall 46 of the first bracket 24 to make the second wall 34b of the second rail 26 located between the second supporting section 44a and the side wall 46 of the first bracket 24, so as to prevent the transverse movement of the second rail 26 (for example, the movement of the second rail 26 from the left or the right in fig. 7 can be prevented, but is not limited in implementation); preferably, the second support portion 44 further comprises another second support section 44b for providing a support effect to the second wall 34b of the second rail 26 in the vertical direction (e.g. preventing the second rail 26 from moving from the lower side of fig. 7).
As shown in fig. 8, a carrier 56 (e.g., an electronic device or a drawer) is mounted to the rack at two sides thereof by two rail assemblies 20. The structural configuration of each slide rail assembly 20 is disclosed in the above description of fig. 1 to 7, and for the sake of brevity, will not be described again here. Further, each of the rail assemblies 20 can be mounted to a corresponding first mast 54a via the bracket 24.
It should be noted that the width between the two first posts 54a of the rack and the width of the carrier 56 are substantially standardized, that is, the width of the two track assemblies 20 is narrower or thinner if the carrier width W1 of the carrier 56 is wider, or the width of each track assembly 20 is wider or thicker if the carrier width W1 of the carrier 56 is narrower, so that the carrier 56 can be correspondingly mounted between the two first posts 54a of the rack through the track assemblies 20.
Further, in the first embodiment of the present invention, since each second wall segment K2 of the third rail 28 of the slide rail assembly 20 is correspondingly located within the range of the transverse width T of the first rail 22, and/or the longitudinal wall 40 of the third rail 28 and each second wall segment X2 of the first rail 22 are substantially located on the same plane H (this portion can be referred to as fig. 7), the overall width W2 of the slide rail assembly 20 is reduced, which is favorable for the carrier 56 with the wider carrier width W1 to be mounted to the slide rail assembly 20.
Fig. 9 shows a slide rail assembly according to a second embodiment of the present invention. Further, different from the first embodiment in which the first supporting portion 42 and the second supporting portion 44 of the slide rail assembly are integrated in the first bracket 24, the difference between the second embodiment and the first embodiment is substantially: the first support portion 202 and the second support portion 204 are additional components mounted on the first bracket 200.
Fig. 10 shows a slide rail assembly according to a third embodiment of the invention. Further, different from the first embodiment in which the first supporting portion 42 and the second supporting portion 44 of the slide rail assembly are integrated in the first bracket 24, the difference between the third embodiment and the first embodiment is substantially: the first supporting portion 302 and the second supporting portion 304 are disposed on the first rail 300.
Further, the first support 302 and the second support 304 can be extension arms extending longitudinally from the first wall 30a and the second wall 30b of the first rail 22. According to this configuration, when the second rail 26 is in the extended position P2 relative to the first rail 300, the first supporting portion 302 and the first wall 34a of the second rail 26 provide mutual support, and the second supporting portion 304 and the second wall 34b of the second rail 26 provide mutual support.
From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:
1. when the second rail 26 is longitudinally displaced from the retracted position P1 to an extended position P2 relative to the first rail 22 in an opening direction, the first supporting portion 42 and the first wall 34a of the second rail 26 are provided for supporting each other, preferably, the second supporting portion 44 and the second wall 34b of the second rail 26 are provided for supporting each other, and the side wall 46 of the first bracket 24 and the longitudinal wall 36 of the second rail 26 are provided for supporting each other.
2. Each second wall section K2 of the third rail 28 is correspondingly located within the range of the transverse width T of the first rail 22, and in addition, the longitudinal wall 40 of the third rail 28 and each second wall section X2 of the first rail 22 are located substantially on the same plane H, so that the overall width of the slide rail assembly can be reduced according to these structural features.
3. The first extending section M1, the first bending section B1, the second extending section M2 and the second bending section B2 are in a continuous bending structure, so that the structural strength of the second rail 26 can be enhanced, which is helpful for improving the overall structural strength of the sliding rail assembly.
4. The second bending section B2 of the second rail 26 and the first wall section K1 of the third rail 28 can provide mutual support to each other so as to enhance the support strength between the second rail 26 and the third rail 28.
5. The first longitudinal section L1 and the second longitudinal section L2 are respectively bent from two ends of the middle section L3, so that the connection between two ends of the middle section L3 and the first longitudinal section L1 and the second longitudinal section L2 also has a structural reinforcement effect.
6. The first supporting portion 42 is used for at least providing the support of the first wall 34a of the second rail 26 in the transverse direction and/or providing the support of the first wall 34a of the second rail 26 in the vertical direction; preferably, the second supporting portion 44 is used for at least providing the second wall 34b of the second rail 26 with support in the transverse direction and/or providing the second wall 34b of the second rail 26 with support in the vertical direction.
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.
