[0016] As Figure 1 illustrated in FIG. 1, an embodiment of the present application includes a slide rail assembly 20 having a first rail 22, a second rail 24, and an operating device 26. The second rail 24 is longitudinally displaceable relative to the first rail 22. Herein, 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). Figure 2 Preferably, the slide rail assembly 20 further includes a third rail 28 movably mounted between the first rail 22 and the second rail 24, wherein the second rail 24 is movably mounted to a channel 29 (as shown in FIG. 2) of the third rail 28.

[0017] Figure 2 Preferably, the first rail 22 is provided with a support frame 30, and the first rail 22 is mountable to a rack 32, such as at least a first post 34a and a second post 34b of the rack 34, via the support frame 30. In addition, the support frame 30 is connected (e.g., fixedly connected) to the first rail 22 and can be considered as a part of the first rail 22. Since this part is within the technical scope that those skilled in the art can understand, for the sake of simplicity, it will not be described here.

[0018] The slide rail assembly 20 (of the operating device 26) includes a fitting 36. In the first embodiment, the fitting 36 is mounted to the second rail 24. For example, the fitting 36 is detachably mounted to the second rail 24 via at least one connecting member 38. Alternatively, in other alternative embodiments, the fitting 36 and the second rail 24 have matching connecting features to be detachably mounted to each other in a snap-fit, plug-in, and / or buckle manner. When the fitting 36 is mounted and fixed to the second rail 24, the fitting 36 can be considered as a part of the second rail 24.

[0019] As illustrated in FIG. 3, the fitting 36 has a predetermined feature 39 for the connecting member 38 to connect, preferably a hole, such as a threaded hole, but the implementation is not limited thereto. Further, the slide rail assembly 20 (of the operating device 26) further includes a latch member 40 and an operating member 42, and preferably further includes a resilient member 44.

[0020] Figure 3 The resilient member 44 is used to provide an elastic force F to the latch member 40. The operating member 42 is used to operate the latch member 40. Figure 4 Preferably, one of the latch member 40 and the operating member 42 is movably mounted to the fitting 36, and herein, both the latch member 40 and the operating member 42 are movably mounted to the fitting 36.

[0021]

[0022] ​​​

[0023] Preferably, the accessory 36 comprises a first predetermined portion 48 and a second predetermined portion 50 connected to the first predetermined portion 48, wherein the second predetermined portion 50 is substantially perpendicularly connected to the first predetermined portion 48, but the implementation is not limited thereto. The catch 40 is pivotally connected to the first predetermined portion 48 via a first shaft 52, and the operation member 42 is pivotally connected to the second predetermined portion 50 via a second shaft 54.

[0024] Preferably, the catch 40 can be kept in a catch state K1 in response to the elastic force F of the elastic member 44, and when the catch 40 is in the catch state K1, the operation member 42 is in a first state S1.

[0025] Preferably, the catch 40 in the catch state K1 can be used to support the operation member 42 to keep it in the first state S1.

[0026] Preferably, one of the catch 40 and the operation member 42 comprises at least one guide feature, such as a slope or an arc, wherein the catch 40 and the operation member 42 have a first guide feature 58a and a second guide feature 58b corresponding to each other, but the implementation is not limited thereto. Through the mutual support of the first guide feature 58a and the second guide feature 58b, the catch 40 in the catch state K1 can be used to keep the operation member 42 in the first state S1.

[0027] Preferably, the operation member 42 comprises an operation portion 60 and a driving portion 62, and the second shaft 54 is located between the operation portion 60 and the driving portion 62. The driving portion 62 is arranged with the second guide feature 58b. In addition, when the operation member 42 is in the first state S1, the operation portion 60 of the operation member 42 and the second predetermined portion 50 of the accessory 36 are mutually away from each other and have a predetermined distance M, such as a predetermined longitudinal distance (as shown in Figure 3

[0028] Preferably, the elastic member 44 comprises a first elastic portion 64 and a second elastic portion 66, the first elastic portion 64 is supported on a corresponding portion of the accessory 36 (of the first predetermined portion 48), and the second elastic portion 66 contacts the catch 40.

[0029] As shown in Figure 5 Since the accessory 36 is fixedly installed to the second rail 24, the accessory 36 can be regarded as a part of the second rail 24, and the operation member 42 is movably installed on the second rail 24, for example, the accessory 36 movably installed on the second rail 24. Further, the second rail 24 has a first end portion 24a and a second end portion 24b opposite to each other, for example, a front end portion and a rear end portion. ​

[0030] Preferably, the second rail 24 has a first side L1 and a second side L2 that are positioned opposite each other; the first side L1 of the second rail 24 is adjacent to the first rail 22, and the operating member 42 is located between the first end 24a and the second end 24b of the second rail 24 and adjacent to the second side L2 of the second rail 24.

[0031] Preferably, the operating member 42 is disposed near the first end 24a of the second rail 24, and the operating member 42 does not extend beyond the first end 24a of the second rail 24.

[0032] Preferably, the second shaft 54 ​​is configured in a direction substantially the same as a height direction (e.g., the Z-axis direction) of the second rail 24, and the first shaft 52 is configured in a direction substantially the same as the height direction of the second rail 24.

[0033] The first track 22 is provided with a blocking feature 68, which is provided in the support frame 30 of the first track 22 as an example; or, in other alternative embodiments, the blocking feature 68 can be directly arranged in the first track 22, so the implementation is not limited.

[0034] When the second rail 24 is in a predetermined position relative to the first rail 22, such as a retracted position R, the second rail 24 is blocked by the blocking feature 68 through the locking member 40 in the locked state K1, to prevent the second rail 24 from displacing from the retracted position R in a first direction D1 and / or in a second direction D2 opposite to the first direction D1. Here, the first direction D1 is an opening direction and the second direction D2 is a retracting direction, but the implementation is not limited.

[0035] like Figure 6 and Figure 7 As shown, the operating member 42 is used to drive the locking member 40, so that the locking member 40 moves relative to the first rail 22 (support frame 30), so that the locking member 40 is no longer blocked by the blocking feature 68, so that the second rail 24 can be displaced from the retracted position R to the first direction D1 (or the second direction D2).

[0036] For example, the user can apply a predetermined force greater than the elastic force F of the elastic member 44 to the operating part 60 of the operating member 42. The operating part 60 of the operating member 42 then moves closer to the second predetermined part 50 of the accessory 36, causing the operating member 42 to move from the first state S1 to a first rotational direction r1 to a second state S2. This allows the driving part 62 of the operating member 42 to drive the locking member 40 from the locking state K1 to a second rotational direction r2 to a released state K2, so that the locking member 40 is no longer blocked by the first stop 70 (or the second stop 72) of the blocking feature 68 (e.g., ...). Figure 6to allow the second rail 24 to be displaced from the retracted position R to the first direction D1 (or the second direction D2) (as shown in FIG. 1C). Figure 7 As shown in FIG. 1C, the second rail 24 has been displaced from the retracted position R to the first direction D1 by a distance relative to the first rail 22). Wherein the first rotation direction r1 and the second rotation direction r2 are opposite directions, but the implementation is not limited thereto. Wherein when the latch 40 is in the unlatched state K2, the elastic member 44 is in a state of accumulating the elastic force F.

[0037] Preferably, the user can hold the second predetermined portion 50 of the accessory 36 and the operation portion 60 of the operation member 42 by hand, and apply the predetermined force to the operation portion 60 of the operation member 42, so that the operation member 42 is moved from the first state S1 to the second state S2.

[0038] It is worth mentioning that when the user stops applying the predetermined force to the operation member 42, and the second rail 24 returns to the retracted position R from another predetermined position, such as an extended position, to the second direction D2 relative to the first rail 22, the latch 40 can return from the unlatched state K2 to the latched state K1 in response to the elastic member 44 releasing the elastic force F to latch to the blocking feature 68, so that the second rail 24 is again maintained in the retracted position R relative to the first rail 22.

[0039] As shown in FIG. 1C, Figure 8 A sliding rail assembly of a second embodiment of the present application is shown, wherein the second rail 200 is used to carry a carrier 202. The difference between this second embodiment and the first embodiment is that the accessory 204 is used to be mounted on the carrier 202.

[0040] For example, the accessory 204 further comprises an extension portion 205, and the accessory 204 can be detachably mounted to the carrier 202 by passing through the extension portion 205 through at least one connecting member 206. Alternatively, in other alternative embodiments, the accessory 204 and the carrier 202 have matching connection features to be detachably mounted to each other by means of clamping, plugging and / or buckling, etc. Wherein when the accessory 204 is fixedly mounted to the carrier 202, the accessory 204 can be considered as a part of the carrier 202, and the operation member 208 and the latch 210 are movably mounted on the carrier 202, for example, movably mounted on the accessory 204 on the carrier 202.

[0041] Wherein the relevant technical principles for how to release the second rail 200 from being blocked by the blocking feature 216 of the support frame 214 of the first rail 212 when the second rail 200 is in the retracted position R have been disclosed in the first embodiment, and for the sake of brevity, they will not be described again here.

[0042] Therefore, it can be seen that the sliding rail assembly 20 of the embodiments of the present application comprises the following features:

[0043] 1. The operation member 42 can drive the latch member 40 to allow the second rail 24 to be displaced relative to the first rail 22 from a predetermined position (e.g. the retracted position R) to the first direction D1, so that the latch member 40 is no longer blocked by the blocking feature 68.

[0044] 2. When the second rail 24 is displaced relative to the first rail 22 from another predetermined position (e.g. the extended position) to the second direction D2 back to the predetermined position (e.g. the retracted position R), the latch member 40 can be released from the unlatched state K2 to the latched state K1 to latch to the blocking feature 68 in response to the elastic member 44 releasing the elastic force F, so that the second rail 24 is kept in the predetermined position relative to the first rail 22.

[0045] 3. When the operation member 42 is in the first state S1, the operation portion 60 of the operation member 42 and the second predetermined portion 50 of the accessory 36 are distanced from each other and have the predetermined distance M (as shown) therebetween; the user can hold the second predetermined portion 50 of the accessory 36 and the operation portion 60 of the operation member 42 by hand, and apply a predetermined force to the operation portion 60 of the operation member 42, so that the operation portion 60 of the operation member 42 is accordingly moved towards the second predetermined portion 50 of the accessory 36, and the operation member 42 is moved from the first state S1 to the second state S2, thus the second predetermined portion 50 of the accessory 36 and the operation portion 60 of the operation member 42 can be easily held and operated by the user.
