[0019] like Figures 1 to 3 As shown in FIG. 1 , a rail assembly 20 according to an embodiment of the present invention comprises a first rail 22, a second rail 24, an elastic member 26 and a latch member 28. The second rail 24 can be longitudinally displaced relative to the first rail 22. Figure 1 In the figure, the X-axis is the longitudinal direction (or the length direction of the slide rail), the Y-axis is the transverse 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).

[0020] The first rail 22 is provided with a latch feature 30. The first rail 22 has a front end f1 and a rear end r1. Preferably, the first rail 22 includes a first wall 32a, a second wall 32b and an intermediate wall 34 connected between the first wall 32a and the second wall 32b of the first rail 22, and the first wall 32a, the second wall 32b and the intermediate wall 34 jointly define a channel 36 for providing the second rail 24 with a movable installation. For example, the channel 36 can be used to accommodate the second rail 24 (this part can be referred to in conjunction with Fig. 9 ).

[0021] Preferably, the latch feature 30 is located within the channel 36 of the first rail 22 .

[0022] The second rail 24 has a front end f2 and a rear end r2. Preferably, the second rail 24 includes a first wall 38a, a second wall 38b and a middle wall 40 connected between the first wall 38a and the second wall 38b of the second rail 24, and the elastic member 26 is arranged on the middle wall 40 of the second rail 24. The second rail 24 can be used to carry a load (such as a case or a drawer).

[0023] Preferably, the elastic member 26 is a V-shaped spring sheet, and the elastic member 26 includes a first elastic arm 42 that abuts against a predetermined mounting portion 43 of the middle wall 40 of the second rail 24, and a second elastic arm 44 for supporting the latching member 28. Here, the middle wall 40 of the second rail 24 has an opening 45 (such as Figure 2As shown), the elastic member 26 is used to be installed in the opening 45, which can reduce the space occupied by the elastic member 26 on both sides of the second rail 24, wherein the predetermined installation portion 43 is arranged in the opening 45 to support the elastic member 26 (the first elastic arm 42).

[0024] Preferably, the latch feature 30 includes a first straight wall 46 , a second straight wall 48 , and a middle portion 50 connected between the first straight wall 46 and the second straight wall 48 .

[0025] The latching member 28 is movably mounted on the second rail 24 and adjacent to the front end f2 of the second rail 24. The latching member 28 is maintained in a latching state S1 in response to the elastic force generated by the elastic member 26.

[0026] Preferably, the latching member 28 is movably mounted on the middle wall 40 of the second rail 24 . Here, the latching member 28 is pivotally connected to the middle wall 40 of the second rail 24 via a shaft 51 as an example, but the implementation is not limited thereto.

[0027] Preferably, the latching member 28 includes a latching portion 52 and a guide portion 54 adjacent to the latching portion 52. Here, the latching member 28 further includes an operating portion 56 and a connecting portion 58 bent relative to the operating portion 56. For example, the connecting portion 58 is substantially vertically connected to the operating portion 56 in the height direction, but the implementation is not limited thereto. The shaft member 51 is located between the latching portion 52 and the operating portion 56.

[0028] When the second rail 24 is in a retracted position R relative to the first rail 22, the latch member 28 (the latch portion 52) forms a latching relationship with the latch feature 30 (the second straight wall 48) of the first rail 22, so that the second rail 24 is locked in the retracted position R relative to the first rail 22 to prevent the second rail 24 from being opened from the retracted position R.

[0029] Preferably, the front end f1 of the first rail 22 is connected to a bent portion 60 in a transverse (lateral) vertical direction; the front end f2 of the second rail 24 is arranged with a bent section, and the bent section can be used as a handle 62, for example, the front end f2 of the second rail 24 is connected to the handle 62 in a transverse (lateral) vertical direction. The bending direction of the bent portion 60 relative to the first rail 22 and the bending direction of the handle 62 relative to the second rail 24 are in the same direction and are substantially parallel to each other. When the second rail 24 is locked in the folded position R relative to the first rail 22, a predetermined space K is defined between the handle 62 of the second rail 24 and the bent portion 60 of the first rail 22.

[0030] like Figures 3 to 6 As shown, when a force F1 is applied to the latch member 28 to overcome the elastic force generated by the elastic member 26 (as shown in FIG. Figure 4 and Figure 5 As shown), the latching member 28 can be in the latching state S1 (as shown Figure 3 As shown) moves to a release state S2 (as shown Figure 4 and Figure 5 ), to allow the second rail 24 to move relative to the first rail 22 from the folded position R to an opening direction D1 (as shown in FIG. Figure 6 Further, when the operating portion 56 of the latching member 28 is exerted with the force F1, the latching member 28 can be changed from the latching state S1 (as shown in FIG. Figure 3 ) moves to the unlocked state S2 (as shown Figure 4 and Figure 5 As shown), another force F2 can be applied to the opening direction D1 through the handle 62 of the second rail 24, so that the second rail 24 can be easily operated to move from the folded position R to the opening direction D1 relative to the first rail 22 (as shown in FIG. Figure 6 shown).

[0031] For example, when the user applies the force F1 to the operating portion 56 of the latch 28 through a first finger h1 of the hand H (eg Figure 4 and Figure 5 As shown), the latching member 28 can be in the latching state S1 (as shown Figure 3 ) moves to the unlocked state S2 (as shown Figure 4 and Figure 5 ), the latching member 28 (the latching portion 52) is released from the latching feature 30 (the second straight wall 48) of the first rail 22, and the user can extend a second finger h2 of the hand H into the predetermined space K and apply another force F2 in the opening direction D1 to the handle 62 of the second rail 24 (as shown in FIG. Figure 4 and Figure 5 ), so that the second rail 24 can move from the folded position R to the opening direction D1 to an extended position E (as shown) relative to the first rail 22. Figure 6 shown).

[0032] It is worth mentioning that the handle 62 can be directly or indirectly connected to the second rail 24; or, the handle 62 can be an additional object connected or detachably installed on the second rail 24, and the implementation is not limited. In addition, although this embodiment arranges the bending section at the front end f2 of the second rail 24 as the handle 62, however, in an alternative embodiment, the second rail 24 can be arranged with an auxiliary space or auxiliary hole, and the auxiliary space or auxiliary hole and its inner wall can be used as the handle 62. For example, the auxiliary space or auxiliary hole can provide a user's finger to extend into, and the inner wall of the auxiliary space or auxiliary hole is used to facilitate the user's finger to apply the other force F2 to the second rail 24. Therefore, the implementation type of the handle 62 of the second rail 24 is not limited to the bending section disclosed in this embodiment.

[0033] In addition, when the force F1 is applied to the latching member 28 to move the latching member 28 from the latching state S1 to the unlocking state S2, the elastic member 26 accumulates an elastic force (such as Figure 4 When the second rail 24 is in the extended position E and the user stops applying the force F1 to the latch member 28 (operating portion 56), the latch member 28 responds to the elastic member 26 releasing the elastic force and recovers from the unlocked state S2 to the locked state S1 (as shown); Figure 6 shown).

[0034] like Figure 7 , Figure 8 and Figure 3 As shown, when the second rail 24 moves relative to the first rail 22 from the extended position E to the retracted position R in a retracted direction D2, the guide portion 54 of the latch member 28 abuts against the first straight wall 46 of the latch feature 30 (as shown in FIG. Figure 7 As shown), and deflects at an angle to pass over the first straight wall 46 and abut against the middle portion 50. At this time, the elastic member 26 generates a predetermined elastic force J (as shown) in response to the deflection displacement of the latch member 28. Figure 8 ), until the latch member 28 passes over the middle portion 50 of the latch feature 30, releasing the predetermined elastic force (such as Figure 3 As shown in FIG. 1 , the latch portion 52 of the latch member 28 can abut against the second straight wall 48 of the latch feature 30 , so that the second rail 24 is locked in the folded position R relative to the first rail 22 .

[0035] like Fig. 9 As shown, the first wall 38a and the second wall 38b of the second rail 24 are supported by the first wall 32a and the second wall 32b of the first rail 22, respectively, and the middle wall 40 of the second rail 24 and the first wall 32a and the second wall 32b of the first rail 22 are substantially located in the same plane M, which is conducive to the thinning of the slide rail kit 20. Further, the middle wall 40 of the second rail 24 is bent relative to the first wall 38a and the second wall 38b of the second rail 24, and the middle wall 40 of the second rail 24 includes an inner surface 64 and an outer surface 66 that are located opposite to each other, and the outer surface 66 of the middle wall 40 of the second rail 24 and a first wall surface 68 of the first wall 32a and a second wall surface 70 of the second wall 32b of the first rail 22 are substantially located in the same plane M, thereby facilitating the thinning of the slide rail kit 20 in the lateral direction (or side direction).

[0036] Preferably, the latching member 28 is movably mounted on the inner surface 64 of the middle wall 40 of the second rail 24 (this part can be referred to in conjunction with Figure 2 ).

[0037] like Figure 1 , Fig.10 and Fig.11 As shown, the bent portion 60 of the first rail 22 has a first mounting hole 72 and a screw seat 74 corresponding to the mounting hole 72. Further, the rail assembly 20 can be mounted to a rack 76 (or column), and the rack 76 has a second mounting hole 78. The connecting portion 58 of the latch 28 has a predetermined hole 80 corresponding to the first mounting hole 72 and the second mounting hole 78.

[0038] Furthermore, when the second rail 24 is in the retracted position R relative to the first rail 22, the user can insert a locking accessory 82 (such as a screw) into the predetermined hole 80, the second mounting hole 78 and the first mounting hole 72, and lock the locking accessory 82 to the screw seat 74, thereby fixing the slide rail kit 20 to the rack 76. Such a configuration helps, for example, to ensure stable and reliable safety when the second rail 24 is loaded with a load to transport the rack 76.

[0039] It can be seen that the slide rail assembly 20 of the embodiment of the present invention has the following features:

[0040] 1. The second rail 24 has a locking function when it is in the retracted position R relative to the first rail 22 .

[0041] 2. The latch 28 can be applied with a force F1 to release the locking relationship between the latch 28 and the first rail 22, and the handle 62 of the second rail 24 can be applied with another force F2, so that the second rail 24 can move from the folded position R to the opening direction D1 relative to the first rail 22. The handle 62 can be used to facilitate the user to apply force to pull the second rail 24 relative to the first rail 22 in the opening direction D1, or to fold it in the folding direction D2.

[0042] 3. When the second rail 24 is in the retracted position R relative to the first rail 22, in addition to being able to lock the second rail 24 relative to the first rail 22 in the retracted position R by engaging the latch 28 with the latch feature 30 of the first rail 22, the locking accessory 82 can also be inserted into the connection portion 58 (the predetermined hole 80) and the bending portion 60 (the first mounting hole 72 and the screw seat 74) to further strengthen the second rail 24 relative to the first rail 22 in the retracted position R. Such a configuration, for example, helps to ensure safety when transporting the rail assembly 20. Alternatively, when the second rail 24 is in the retracted position R relative to the first rail 22, the user can use the locking accessory 82 to fix the rail assembly 20 to the rack 76 (such as Fig.10 or Fig.11 ), so that the second rail 24 is maintained at the folded position R relative to the first rail 22. Such a configuration, for example, helps to ensure stable and reliable safety when the second rail 24 is loaded with loads to transport the rack 76.

[0043] 4. The outer surface 66 of the middle wall 40 of the second rail 24 and the first wall surface 68 of the first wall 32 a and the second wall surface 70 of the second wall 32 b of the first rail 22 are substantially in the same plane M, thereby facilitating the thinning of the slide rail kit 20 .

[0044] 5. The middle wall 40 of the second rail 24 has an opening 45 (such as Figure 2 As shown in FIG. 4 , the elastic member 26 is used to be installed in the opening 45 , which can reduce the space occupied by the elastic member 26 on both sides of the second rail 24 .

[0045] Although the present invention has been described with reference to the current specific embodiments, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and various equivalent changes and modifications may be made without departing from the spirit of the present invention. Therefore, any changes and modifications to the above embodiments within the spirit of the present invention will fall within the scope of the claims of this application.
