[0024] like Figure 1 and Figure 2 As shown, a rail assembly 20 of the first embodiment of the present invention includes a first rail 22 (e.g., an outer rail) and a lock 24. Preferably, the rail assembly 20 further includes a bracket 26, a second rail 28 (e.g., a middle rail) and a third rail 30 (e.g., an inner rail). The first rail 22, the second rail 28 and the third rail 30 can be longitudinally displaced relative to each other. Here, the X-axis direction is the longitudinal direction (or the length direction of the rail), the Y-axis direction is the transverse direction (or the lateral direction of the rail), and the Z-axis direction is the vertical direction (or the height direction of the rail).

[0025] The first rail 22 includes a side wall 32. Preferably, the first rail 22 further includes a first wall 34a and a second wall 34b. The side wall 32 of the first rail 22 is connected between the first wall 34a and the second wall 34b of the first rail 22. The first wall 34a, the second wall 34b and the side wall 32 of the first rail 22 together define a channel 36. Preferably, the side wall 32 of the first rail 22 has an outer side L1 and an inner side L2. The second rail 28 is movably mounted in the channel 36 of the first rail 22, and the second rail 28 is located at the inner side L2 of the side wall 32 of the first rail 22. In addition, the third rail 30 is movably mounted in a channel 38 of the second rail 28.

[0026] The bracket 26 is attached to the first rail 22. Here, the bracket 26 is fixed to the first rail 22 so that the bracket 26 and the first rail 22 can be regarded as one body. Alternatively, in an alternative implementation, the bracket 26 can be integrated into the first rail 22. Therefore, the implementation is not limited.

[0027] The lock 24 is arranged on the first rail 22. Further, the lock 24 is movably mounted to the bracket 26.

[0028] Preferably, the slide rail assembly 20 further includes at least one first slide-assisting device 40 movably installed between the first rail 22 and the second rail 28 to assist the relative displacement between the first rail 22 and the second rail 28. Preferably, the at least one first slide-assisting device 40 is taken as an example of two first slide-assisting devices 40 respectively located on the first wall 34a and the second wall 34b in the channel 36 of the first rail 22, but the implementation is not limited thereto. Each first slide-assisting device 40, for example, includes a plurality of balls 41. Figure 1 and Figure 2 Only one first sliding aid device 40 is shown.

[0029] Preferably, the slide rail assembly 20 further includes a second slide-assisting device 42 movably mounted between the second rail 28 and the third rail 30 to assist the relative displacement between the second rail 28 and the third rail 30. The second slide-assisting device 42 includes a ball retainer 44 and a plurality of balls 46 mounted on the ball retainer 44.

[0030] like Figure 3 and Figure 4 As shown, the bracket 26 includes a first side portion 48a, a second side portion 48b, and a side portion 50 connected between the first side portion 48a and the second side portion 48b. The side portion 50 of the bracket 26 is fixed to the outer side L1 (such as the side wall 32 of the first rail 22) of the first rail 22. Figure 3 As shown), the first side portion 48a and the second side portion 48b of the bracket 26 respectively embrace the first wall 34a and the second wall 34b of the first rail 22, thereby helping to improve the structural strength or support strength of the first rail 22.

[0031] Furthermore, the first rail 22 is provided with at least one mounting feature 52, wherein the side portion 50 (eg, Figure 3). The mounting feature 52 is, for example, a latch. Preferably, the mounting feature 52 has a first predetermined section 54 and a second predetermined section 56. The first predetermined section 54 extends transversely (laterally) from the side portion 50 of the bracket 26; the second predetermined section 56 is bent relative to the first predetermined section 54. For example, the second predetermined section 56 is substantially perpendicular to the first predetermined section 54, and the second predetermined section 56 is substantially parallel to the length direction of the first rail 22 (and the bracket 26) (as shown in FIG. Figure 3 ), but is not limited in implementation.

[0032] The lock member 24 includes at least one lock portion 58 and an operating portion 60. The lock portion 58 can remain located at the outer side L1 (eg, Figure 3 As shown), further, the lock member 24 can be in a locked state K1 in response to the elastic force F of the elastic portion 62, so that the lock portion 58 of the lock member 24 remains located at the outer side L1 of the side wall 32 of the first rail 22.

[0033] Preferably, the locking member 24 is pivotally connected to the bracket 26 via a shaft member 64 . Here, the locking member 24 is pivotally connected to at least one lug 65 of the bracket 26 via the shaft member 64 as an example.

[0034] Preferably, the elastic portion 62 includes a first elastic section 66 and a second elastic section 68 and an intermediate portion 70 connected between the first elastic section 66 and the second elastic section 68, and the intermediate portion 70 is, for example, mounted to the shaft 64; the first elastic section 66 contacts one of the bracket 26 and the first rail 22, and here, the first elastic section 66 is connected to a predetermined portion 72 of the bracket 26 as an example; the second elastic section 68 contacts the lock 24.

[0035] Preferably, the first rail 22 has a first end 22 a and a second end 22 b that are opposite to each other, such as a front end and a rear end; the locking element 24 is located adjacent to the first end 22 a of the first rail 22 .

[0036] Preferably, the first rail 22 includes a predetermined hole 74 connecting the outer side L1 and the inner side L2 of the side wall 32 , and the position of the predetermined hole 74 at least corresponds to the position of the operating portion 60 of the lock 24 to facilitate the user's finger to operate the operating portion 60 of the lock 24 .

[0037] like Figure 4 and Figure 5As shown in FIG. 1 , if the lock member 24 is to be operated to leave the locked state K1, the user may apply an operating force J to the lock member 24. For example, the user's finger may pass through a predetermined space 75 of the predetermined hole 74 on the inner side L2 of the first rail 22 to the outer side L1 of the first rail 22, and apply the operating force J to the operating portion 60 of the lock member 24 in the direction opposite to the elastic force F, so as to overcome the elastic force F and move the lock member 24 from the locked state K1 (as shown in FIG. 1 ). Figure 4 As shown) moves to an unlocked state K2 (as shown Figure 5 As shown), the locking portion 58 of the locking member 24 is moved toward the inner side L2 of the side wall 32 of the first rail 22.

[0038] like Figure 6 and Figure 7 As shown, the slide rail kit 20 can be applied to a rack 76, and the rack 76 includes at least one column, such as at least one first column 78 and a second column 80, but the number is not limited in practice. Among them, the first column 78 of the rack 76 includes a plurality of mounting structures 82, and these mounting structures 82 are arranged with a spacing from each other along the height direction of the rack 76. Here, these mounting structures 82 are all mounting holes as an example, but the implementation is not limited; the rack 76 also includes a retaining wall 83, and here, the second column 80 includes the retaining wall 83 as an example, but the implementation is not limited. In addition, the locking portion 58 of the locking member 24 includes a guide section 84, and the guide section 84 is, for example, an inclined surface or an arc surface.

[0039] Furthermore, the rail assembly 20 can be mounted to the rack 76 (eg, Figure 7 As shown), during this installation process, the mounting feature 52 on the bracket 26 of the first rail 22 can be laterally (laterally) penetrated into the mounting structure 82 (mounting hole). At this time, the first rail 22 is at a predetermined position P1 (such as Figure 6 As shown), and the guide section 84 of the locking portion 58 corresponds to or contacts the side of the retaining wall 83 of the frame 76, so that the elastic portion 62 is in a state of accumulating the elastic force F (as shown Figure 6 shown).

[0040] When the first rail 22 moves from the predetermined position P1 to a first predetermined direction D1 (such as Figure 6 As shown) moves to an installation position P2 (as shown Figure 7 ), the mounting feature 52 of the first rail 22 can mount the first rail 22 to the mounting structure 82 of the rack 76. Specifically, the mounting feature 52 of the first rail 22 is used to mount to the mounting structure 82 and is blocked by a hole wall W of the mounting structure 82 to prevent the first rail 22 from moving relative to the rack 76 in the first predetermined direction D1. In addition, when the first rail 22 is in the mounting position P2 relative to the rack 76 (as shown in FIG. Figure 7 ), the guide section 84 of the locking portion 58 no longer corresponds to (no longer contacts) the side of the retaining wall 83 of the frame 76, so that the locking member 24 responds to the elastic portion 62 releasing the elastic force F and is in the locked state K1 (as shown in FIG. Figure 7 ), further, the locking portion 58 can be located at the outer side L1 of the side wall 32 of the first rail 22 in response to the elastic force F of the elastic portion 62 to form the locking state K1 with the frame 76, so that the locking portion 58 of the locking member 24 can be blocked by the blocking wall 83 of the second column 80 of the frame 76. In other words, through the blocking relationship between the locking portion 58 of the locking member 24 and the blocking wall 83 of the frame 76, the first rail 22 can be prevented from moving in a second predetermined direction D2 relative to the frame 76, so that the mounting feature 52 of the first rail 22 cannot be released from the mounting structure 82 (as shown in FIG. Figure 7 Wherein, the first predetermined direction D1 and the second predetermined direction D2 are opposite directions.

[0041] Preferably, when the first rail 22 is at the installation position P2 relative to the frame 76 (eg Figure 7 ), the first predetermined section 54 of the mounting feature 52 is blocked by the hole wall W of the mounting structure 82 in the first predetermined direction D1; and the first predetermined section 54 of the mounting feature 52 is blocked by an upper hole wall 77 and a lower hole wall 79 of the mounting structure 82 in the height direction to prevent the first rail 22 from moving relative to the frame 76 in the height direction; in addition, the second predetermined section 56 of the mounting feature 52 can hold a predetermined side surface 86 of the hole wall W (the predetermined side surface 86 can be used in conjunction with Figure 6 ).

[0042] like Figure 7 and Figure 8 As shown, when the first rail 22 is to be removed from the frame 76, the user can apply the operating force J to the operating portion 60 of the lock 24 to change the lock 24 from the locked state K1 (as shown in FIG. Figure 7 As shown) moves to the unlocked state K2 (as shown Figure 8 In other words, the locking state K1 can be released through the operating portion 60 to release the blocking relationship between the locking portion 58 of the locking member 24 and the blocking wall 83 of the frame 76 (as shown in FIG. Figure 8 As shown in the figure, the locking portion 58 of the locking member 24 no longer forms the locking state K1 with the retaining wall 83 of the rack 76, thereby allowing the first rail 22 to move from the installation position P2 to the second predetermined direction D2 relative to the rack 76, and the installation feature 52 can be released from the installation structure 82 of the rack 76 and leave, so that the first rail 22 can be removed from the rack 76.

[0043] Preferably, when the first rail 22 is to be removed from the frame 76, the user may first remove the third rail 30 from the channel 38 of the second rail 28 (eg, Figure 8 wherein, when the third rail 30 is removed from the channel 38 of the second rail 28 and the second rail 28 is in a retracted position R relative to the first rail 22 (such as Figure 8 ), the second rail 28 does not cover the operating portion 60 of the lock 24, so as to facilitate the user to operate the lock 24 from the inner side L2 of the side wall 32 of the first rail 22. For example, the user's finger can pass through the predetermined space 75 of the predetermined hole 74 on the inner side L2 of the first rail 22 to the outer side L1 of the first rail 22, and apply the operating force J to the operating portion 60 of the lock 24, so that the lock 24 is changed from the locked state K1 (as shown in FIG. Figure 7 As shown) moves to the unlocked state K2 (as shown Figure 8 As shown), the blocking relationship between the locking portion 58 of the locking member 24 and the blocking wall 83 of the frame 76 is released.

[0044] like Fig. 9 and Fig.10 The slide rail kit 200 of the second embodiment of the present invention is shown. The difference between the slide rail kit 200 and the first embodiment mainly lies in the configuration relationship between the lock 204 and the first rail 202 of the second embodiment. The first rail 202, the second rail 208 and the third rail 210 of the slide rail kit 200 are substantially the same as those of the first embodiment.

[0045] Furthermore, the first rail 202 includes a first wall 212a, a second wall 212b and a side wall 214 connected between the first wall 212a and the second wall 212b, and the first wall 212a, the second wall 212b and the side wall 214 of the first rail 202 jointly define a channel 216; the second rail 208 is movably installed in the channel 216 of the first rail 202, and the second rail 208 is located on the inner side L2' of the side wall 214 of the first rail 202.

[0046] Preferably, the slide rail assembly 200 further includes at least one first slide-assisting device 218 movably installed between the first rail 202 and the second rail 208 to assist the relative displacement between the first rail 202 and the second rail 208. Preferably, the at least one first slide-assisting device 218 is exemplified by two first slide-assisting devices 218 respectively located on the first wall 212a and the second wall 212b in the channel 216 of the first rail 202, but the implementation is not limited thereto. Each first slide-assisting device 218, for example, includes a plurality of balls 220. Fig.10 Only one first sliding aid device 218 is shown.

[0047] The third rail 210 is movably mounted on a channel 222 of the second rail 208, and a second sliding aid 224 is movably mounted between the second rail 208 and the third rail 210 to facilitate relative displacement between the second rail 208 and the third rail 210. The second sliding aid 224 includes a ball retainer 226 and a plurality of balls 228 mounted on the ball retainer 226.

[0048] like Fig.10 , Fig.11 and Fig.12 As shown, the first rail 202 is provided with at least one mounting feature 223 (eg Fig.11 and Fig.12 As shown in FIG. 1 , here, the installation feature 223 is arranged on an outer side L1' of the side wall 214 of the first rail 202, and the installation feature 223 is a latch, but the implementation is not limited thereto. Preferably, the first rail 202 is provided with an auxiliary member 225 attached (for example, fixedly connected) to the outer side L1' of the side wall 214 of the first rail 202, so that the auxiliary member 225 and the first rail 202 can be regarded as one body (for example, Fig.12 Alternatively, in an alternative embodiment, the auxiliary member 225 can be integrated into the first rail 202 , and thus, the embodiment is not limited. The mounting feature 223 is disposed on the auxiliary member 225 .

[0049] Preferably, the mounting feature 223 has a first predetermined section 227 and a second predetermined section 229, wherein the first predetermined section 227 extends transversely (laterally) from the side of the auxiliary member 225; the second predetermined section 229 is bent relative to the first predetermined section 227, for example, the second predetermined section 229 is substantially perpendicularly connected to the first predetermined section 227, and the second predetermined section 229 is substantially parallel to the length direction of the first rail 202 (and the auxiliary member 225) (e.g. Fig.12 ), but is not limited in implementation.

[0050] The lock 204 includes a lock portion 230, an operating portion 232, and an elastic portion 234. The elastic portion 234 is connected (eg, fixedly connected) to the inner side L2' (eg, inner side L2') of the side wall 214 of the first rail 202 via a connecting member 236. Fig.10 and Fig.11 ), the elastic portion 234 has a predetermined longitudinal length. Preferably, the locking portion 230 is located on the elastic portion 234, and the operating portion 232 is operably connected to the locking portion 230. In this embodiment, the locking portion 230, the elastic portion 234 and the operating portion 232 are integrated into the locking element 204, so that the locking element 204 becomes a single component. The locking portion 230 can remain located at the outer side L1' (as shown in FIG. 1 ) of the side wall 214 of the first rail 202 in response to the elastic force of the elastic portion 234. Fig.12Specifically, the lock element 204 can be in a locked state K1' in response to the elastic force of the elastic portion 234, so that the lock portion 230 of the lock element 204 remains located at the outer side L1' of the side wall 214 of the first rail 202.

[0051] Preferably, the first rail 202 includes an auxiliary hole 238 connecting the outer side L1' and the inner side L2' of the side wall 214 of the first rail 202, and the locking portion 230 of the locking member 204 partially extends from the inner side L2' of the side wall 214 of the first rail 202 to the outer side L1' of the side wall 214 of the first rail 202 through the auxiliary hole 238, wherein the auxiliary member 225 has a corresponding hole 240 corresponding to the auxiliary hole 238, and the corresponding hole 240 allows the locking portion 230 of the locking member 204 to pass through the outer side L1' of the side wall 214 of the first rail 202 (such as Fig.12 shown).

[0052] Preferably, the first rail 202 includes a predetermined hole 242 connecting the outer side L1′ and the inner side L2′ of the side wall 214 of the first rail 202 . The position of the predetermined hole 242 at least corresponds to the position of the operating portion 232 of the lock 204 , so as to facilitate the user's finger to operate the operating portion 232 of the lock 204 .

[0053] Preferably, the locking portion 230 of the locking element 204 includes a guide section 243, such as an inclined surface or a curved surface (such as Fig.12 shown).

[0054] Preferably, the second rail 208 has an opening 244, and the ball retainer 226 has a through hole 246 corresponding to the opening 244 of the second rail 208 (eg, Fig.10 shown).

[0055] like Fig.13 As shown, the slide rail kit 200 can be applied to a rack 248, and the rack 248 includes a plurality of mounting structures 250. Here, it is taken as an example that these mounting structures 250 are all mounting holes, but the implementation is not limited. Each mounting structure 250 is defined by a plurality of hole walls, such as a first hole wall W1 and a second hole wall W2. The first hole wall W1 and the second hole wall W2 are, for example, a front hole wall and a rear hole wall, respectively.

[0056] Further, the rail kit 200 can be installed on the rack 248. During the installation process, the mounting feature 223 of the first rail 202 can be inserted into the mounting structure 250 (mounting hole) transversely (laterally); when the first rail 202 moves from a predetermined position to a second predetermined direction D2 to the mounting position P2' relative to the rack 248, the mounting feature 223 of the first rail 202 can install the first rail 202 to the mounting structure 250 of the rack 248. Specifically, the mounting feature 223 of the first rail 202 is used to be installed on the mounting structure 250 and is blocked by the first hole wall W1 of the mounting structure 250 to prevent the first rail 202 from moving relative to the rack 248 in the second predetermined direction D2. In addition, when the first rail 202 is at the installation position P2' relative to the rack 248, the guide section 243 of the locking portion 230 has passed the side of the second hole wall W2 of the rack 248, so that the locking member 204 is in the locking state K1' in response to the elastic force F' released by the elastic portion 234. Further, the locking portion 230 can be located at the outer side L1' of the side wall 214 of the first rail 202 and the rack 248 in response to the elastic force F' of the elastic portion 234. The locked state K1′ is formed so that the locking portion 230 of the locking member 204 can be blocked by the second hole wall W2 of the mounting structure 250 of the rack 248. In other words, through the blocking relationship between the locking portion 230 of the locking member 204 and the second hole wall W2 of the rack 248, the first rail 202 can be prevented from moving in the first predetermined direction D1 relative to the rack 248, so that the mounting feature 223 of the first rail 202 cannot be released from the mounting structure 250. The first predetermined direction D1 and the second predetermined direction D2 are opposite directions.

[0057] Preferably, when the first rail 202 is in the installation position P2' relative to the rack 248, the first predetermined section 227 of the mounting feature 223 is blocked by the first hole wall W1 of the mounting structure 250 toward the second predetermined direction D2; and, the first predetermined section 227 of the mounting feature 223 is blocked in the height direction by an upper hole wall 252 and a lower hole wall 254 of the mounting structure 250 to prevent the first rail 202 from moving in the height direction relative to the rack 248; in addition, the second predetermined section 229 of the mounting feature 223 can embrace a predetermined side surface 256 of the first hole wall W1.

[0058] like Fig.14 and Fig.15 As shown, when the first rail 202 is to be removed from the frame 248, the user can apply an operating force J' to the operating portion 232 of the lock 204 (eg, Fig.14), so that the lock 204 moves from the locked state K1' to the unlocked state K2'. In other words, the operating portion 232 can be used to release the locked state K1' to release the blocking relationship between the lock portion 230 of the lock 204 and the second hole wall W2 of the frame 248 (as shown in FIG. Fig.15 As shown), the locking portion 230 of the locking member 204 no longer forms the locking state K1' with the second hole wall W2 of the rack 248, thereby allowing the first rail 202 to move from the installation position P2' to the first predetermined direction D1 relative to the rack 248, and the installation feature 223 can be released from the installation structure 250 of the rack 248 and leave, so that the first rail 202 can be removed from the rack 248.

[0059] Preferably, when the first rail 202 is to be removed from the rack 248, the user may first remove the third rail 210 from the channel 222 of the second rail 208 (eg, Fig.14 wherein, when the third rail 210 is removed from the channel 222 of the second rail 208, and the second rail 208 is in a retracted position R' (eg, Fig.14 ), the opening 244 of the second rail 208 corresponds to the operating portion 232 of the lock 204. In other words, the second rail 208 does not cover the operating portion 232 of the lock 204, so as to facilitate the user to operate the lock 204 from the inner side L2' of the side wall 214 of the first rail 202 (as shown in FIG. Fig.14 Preferably, the through hole 246 of the ball retainer 226 of the second slide aid 224 corresponds to the opening 244 of the second rail 208, thereby exposing the operating portion 232 of the lock 204 and facilitating the user to operate the lock 204 from the inner side L2' of the side wall 214 of the first rail 202 (as shown in FIG. Fig.14 For example, the user's finger can be conveniently applied to the operating force J' from the predetermined hole 242 on the inner side L2' of the first rail 202 to the operating portion 232 of the lock 204, so that the lock 204 moves from the above-mentioned locked state K1' to the unlocked state K2' (as shown in FIG. Fig.14 and Fig.15 ), so as to release the blocking relationship between the locking portion 230 of the locking member 204 and the second hole wall W2 of the frame 248 (as shown in FIG. Fig.15 As shown), the first rail 202 can be allowed to move relative to the rack 248 from the installation position P2' to the first predetermined direction D1, and the installation feature 223 can be released and left from the installation structure 250 of the rack 248, so that the first rail 202 can be removed from the rack 248.

[0060] It can be seen from this that the slide rail kit (20; 200) provided in the embodiment of the present invention has the following features:

[0061] 1. Through a tool-free method, it is convenient for a user to quickly install the slide rail kit (20; 200) on the rack (76; 248) or remove it from the rack (76; 248).

[0062] 2. In the first embodiment, the lock 24 can move relative to the first rail 22 (bracket 26), for example, the lock 24 is pivotally connected to the bracket 26 on the first rail 22; it can be installed to the mounting structure 82 of the rack 76 through the mounting feature 52 on the first rail 22 (bracket 26), and the lock portion 58 of the lock 24 can respond to the elastic force F of the elastic portion 62 to be located on the outer side L1 of the side wall 32 of the first rail 22 and form the locking state K1 with the rack 76, so that the mounting feature 52 of the first rail 22 cannot be released from the mounting structure 82 of the rack 76.

[0063] 3. In the first embodiment, when the second rail 28 is in the retracted position R relative to the first rail 22, the second rail 28 will not cover the operating portion 60 of the lock 24, so as to facilitate the user to operate the lock 24 from the inner side L2 of the side wall 32 of the first rail 22. For example, the user applies the operating force J to the operating portion 60 of the lock 24 to move the lock 24 from the locked state K1 to the unlocked state K2. Therefore, the lock 24 and the frame 76 no longer form the locked state K1, so that the mounting feature 52 of the first rail 22 can be released from the mounting structure 82 of the frame 76. According to this configuration, the diversified needs of the market can be met.

[0064] 4. In the second embodiment, the locking portion 230, the elastic portion 234 and the operating portion 232 are integrated into the locking element 204, so that the locking element 204 becomes a single component, and the locking element 204 is connected (for example, fixedly connected) to the first rail 202 through the elastic portion 234; the mounting feature 223 on the first rail 202 can be used to be mounted to the mounting structure 250 of the rack 248, and the locking portion 230 of the locking element 204 responds to the elastic force F' of the elastic portion 234 to be located on the outer side L1' of the side wall 214 of the first rail 202 and form the locking state K1' with the rack 248, so that the mounting feature 223 of the first rail 202 cannot be released from the mounting structure 250 of the rack 248.

[0065] 5. In the second embodiment, when the second rail 208 is in the retracted position R' relative to the first rail 202, the opening 244 of the second rail 208 corresponds to the operating portion 232 of the lock 204. In other words, the second rail 208 will not cover the operating portion 232 of the lock 204, so that the user can operate the lock 204 from the inner side L2' of the side wall 214 of the first rail 202 to move the lock 204 from the locked state K1' to the unlocked state K2'. Therefore, the lock 204 and the frame 248 no longer form the locked state K1', so that the installation feature 223 of the first rail 202 can be released from the installation structure 250 of the frame 248. According to this configuration, the diversified needs of the market can be met.
