[0016] like Figure 1 and Figure 2 As shown, a slide rail assembly 20 of an embodiment of the present invention includes a first rail 22, a second rail 24 and an operating device 26. The second rail 24 and the first rail 22 can be longitudinally displaced relative to each other. Here, 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).

[0017] Preferably, the third rail 28 is movably mounted between the first rail 22 and the second rail 24, wherein the second rail 24 is movably mounted to a channel 29 (such as Figure 2 shown).

[0018] Preferably, the first rail 22 is provided with a support frame 30, through which the first rail 22 can be mounted to a rack 34, for example, mounted to at least a first column 34a and a second column 34b of the rack 34; in addition, the support frame 30 is connected (for example, fixed) to the first rail 22 and can be regarded as a part of the first rail 22. Since this part is a technical scope that can be understood by a person of ordinary knowledge in the field, it will not be further described here for the sake of simplicity.

[0019] The slide rail assembly 20 (operating device 26) includes an accessory 36. In this first embodiment, the accessory 36 is used to be installed on the second rail 24. For example, the accessory 36 is detachably installed on the second rail 24 through at least one connecting member 38. Alternatively, in other alternative embodiments, the accessory 36 and the second rail 24 have mutually matching connection features and are detachably installed with each other in a manner such as snap-on, plug-in and / or buckle. When the accessory 36 is installed and fixed to the second rail 24, the accessory 36 can be regarded as a part of the second rail 24.

[0020] like Figure 3 and Figure 4 As shown, the accessory 36 has a predetermined feature 39 for connecting the above-mentioned connecting member 38. Preferably, the predetermined feature 39 is a hole, such as a screw hole, but the implementation is not limited. Further, the slide rail assembly 20 (operating device 26) also includes a latch member 40 and an operating member 42, and preferably, also includes an elastic member 44.

[0021] The elastic 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 .

[0022] Preferably, one of the latching member 40 and the operating member 42 is movably mounted on the accessory 36 . Here, the example in which both the latching member 40 and the operating member 42 are movably mounted on the accessory 36 is taken.

[0023] Preferably, the accessory 36 includes a first predetermined portion 48 and a second predetermined portion 50 connected to the first predetermined portion 48. Here, the second predetermined portion 50 is substantially vertically connected to the first predetermined portion 48 as an example, but the implementation is not limited thereto. The latch member 40 is pivotally connected to the first predetermined portion 48 via a first shaft member 52, and the operating member 42 is pivotally connected to the second predetermined portion 50 via a second shaft member 54.

[0024] Preferably, the latching member 40 can remain in a latching state K1 in response to the elastic force F of the elastic member 44 , and when the latching member 40 is in the latching state K1 , the operating member 42 is in a first state S1 .

[0025] Preferably, the latching member 40 in the latching state K1 can be used to support the operating member 42 to remain in the first state S1.

[0026] Preferably, one of the latching member 40 and the operating member 42 includes at least one guiding feature, such as an inclined surface or an arc surface. Here, the latching member 40 and the operating member 42 are provided with a first guiding feature 58a and a second guiding feature 58b corresponding to each other, but the implementation is not limited thereto. Through the mutual support of the first guiding feature 58a and the second guiding feature 58b, the latching member 40 in the latching state K1 can be used to keep the operating member 42 in the first state S1.

[0027] Preferably, the operating member 42 includes an operating portion 60 and a driving portion 62, and the second shaft member 54 is located between the operating portion 60 and the driving portion 62. The driving portion 62 is provided with the second guide feature 58b. In addition, when the operating member 42 is in the first state S1, the operating portion 60 of the operating member 42 and the second predetermined portion 50 of the accessory 36 are separated from each other by a predetermined distance M, for example, a predetermined longitudinal distance (e.g., Figure 3 shown).

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

[0029] like Figure 5 As shown, since the accessory 36 is fixedly mounted to the second rail 24, the accessory 36 can be regarded as a part of the second rail 24, and the operating member 42 is movably mounted on the second rail 24, for example, the accessory 36 is movably mounted on the second rail 24. Further, the second rail 24 has a first end 24a and a second end 24b that are opposite to each other, for example, a front end and a rear end.

[0030] Preferably, the second rail 24 has a first side L1 and a second side L2 opposite to 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 24 a of the second rail 24 , and the operating member 42 does not exceed the first end 24 a of the second rail 24 .

[0032] Preferably, the configuration direction of the second shaft member 54 is substantially the same as a height direction (eg, Z-axis direction) of the second rail 24 , and the configuration direction of the first shaft member 52 is substantially the same as the height direction of the second rail 24 .

[0033] The first rail 22 is arranged with a blocking feature 68. Here, it is taken as an example that the blocking feature 68 is arranged on the support frame 30 of the first rail 22; or, in other replaceable embodiments, the blocking feature 68 can be directly arranged on the first rail 22, so the implementation is not limited.

[0034] When the second rail 24 is at 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 latching member 40 in the latching state K1, so as to prevent the second rail 24 from moving from the retracted position R to a first direction D1 and / or 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 retracted direction, but the implementation is not limited thereto.

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

[0036] For example, the user may apply a predetermined force greater than the elastic force F of the elastic member 44 to the operating portion 60 of the operating member 42, and the operating portion 60 of the operating member 42 accordingly approaches the second predetermined portion 50 of the accessory 36, so that the operating member 42 moves from the first state S1 to a first rotation direction r1 to a second state S2, so that the driving portion 62 of the operating member 42 can drive the latching member 40 to move from the latching state K1 to a second rotation direction r2 to a released state K2, so that the latching member 40 is no longer blocked by a first stop portion 70 (or a second stop portion 72) of the blocking feature 68 (such as Figure 6), to allow the second rail 24 to move from the folded position R to the first direction D1 (or the second direction D2) (as shown in FIG. Figure 7 As shown, the second rail 24 has been displaced from the folded position R to the first direction D1 relative to the first rail 22. The first rotation direction r1 and the second rotation direction r2 are opposite to each other, but the implementation is not limited thereto. When the latch 40 is in the unlocked 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 operating portion 60 of the operating member 42 and apply the predetermined force to the operating portion 60 of the operating member 42 to move the operating member 42 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 operating member 42, and the second rail 24 returns to the folded position R relative to the first rail 22 from another predetermined position, such as an extended position, toward the second direction D2, the latch member 40 responds to the elastic member 44 releasing the elastic force F and is able to return from the unlocked state K2 to the engaged state K1 and latch to the blocking feature 68, so that the second rail 24 is maintained in the folded position R relative to the first rail 22 again.

[0039] like Figure 8 The slide rail assembly of the second embodiment of the present invention is shown, wherein the second rail 200 is used to carry a load 202 . The difference between the second embodiment and the first embodiment is essentially that the accessory 204 is used to be installed on the load 202 .

[0040] For example, the accessory 204 further includes an extension 205, and the accessory 204 can be detachably mounted to the carrier 202 through at least one connecting member 206 passing through the extension 205. Alternatively, in other alternative embodiments, the accessory 204 and the carrier 202 have mutually matching connection features and are detachably mounted to each other in a manner of snap connection, plug connection, and / or buckle connection. When the accessory 204 is fixedly mounted to the carrier 202, the accessory 204 can be regarded as a part of the carrier 202, and the operating member 208 and the latch member 210 are movably mounted on the carrier 202, for example, the accessory 204 is movably mounted on the carrier 202.

[0041] The relevant technical principle on how to release the second rail 200 from being blocked by the first rail 212 (the blocking feature 216 of the support frame 214 ) when the second rail 200 is in the folded position R has been disclosed in the first embodiment, and will not be further described here for the sake of simplicity.

[0042] It can be seen that the slide rail assembly 20 of the embodiment of the present invention includes the following features:

[0043] 1. The latching member 40 can be driven by the operating member 42 so that the latching member 40 is no longer blocked by the blocking feature 68 , so as to allow the second rail 24 to move relative to the first rail 22 from a predetermined position (eg, the folded position R) toward the first direction D1 .

[0044] 2. When the second rail 24 returns to the predetermined position (e.g., the folded position R) from another predetermined position (e.g., the extended position) in the second direction D2 relative to the first rail 22, the latch member 40 responds to the elastic member 44 releasing the elastic force F and can return from the unlocked state K2 to the locked state K1 and latch to the blocking feature 68, so that the second rail 24 remains in the predetermined position relative to the first rail 22.

[0045] 3. When the operating member 42 is in the first state S1, the operating portion 60 of the operating member 42 and the second predetermined portion 50 of the accessory 36 are separated from each other by the predetermined distance M (e.g. Figure 3 As shown); the user can hold the second predetermined portion 50 of the accessory 36 and the operating portion 60 of the operating member 42 by hand, and apply a predetermined force to the operating portion 60 of the operating member 42, so that the operating portion 60 of the operating member 42 approaches the second predetermined portion 50 of the accessory 36, so that the operating member 42 moves from the above-mentioned first state S1 to the second state S2. Therefore, the second predetermined portion 50 of the accessory 36 and the operating portion 60 of the operating member 42 can facilitate the user to hold and operate the operating member 42.

[0046] 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.
