Figure 7 is a partial perspective assembled view of the slide rail of Figure 1 during the folding process.

Referring to FIGS. 1 and 3 , a slide rail includes an outer rail 10 , a middle rail 30 , an inner rail 50 , and a latching member 40 mounted on the outer rail 10 . The outer rail 10 is fixed to the column 100 of a cabinet. The middle rail 30 is slidably mounted on the inner side of the outer rail 10, and the inner rail 50 is slidably mounted on the inner side of the middle rail 30.

Referring to FIG. 2 , the outer rail 10 includes a snap opening 11 , two outer rail retaining slots 13 and a limiting opening 15 . The two outer rails allow the positioning slots 13 to be disposed in parallel on both sides of the snap opening 11. The limit opening 15 is substantially rectangular.

The clip 40 includes a body 41. The body 41 includes a first elastic end 411 and a second elastic end 412. A first fastening portion 42 and two protrusions 43 are protruded from the first free end 411 . In one embodiment, the first fastening portion 42 is a convex hull, and the two protruding pieces 43 are curved. The two tabs 43 are parallel to each other and are located on both sides of the first latching portion 42. The second free end of the body 41 is provided with a first limiting portion 45. When the latching member 40 is in the free state, the two free ends are inclined toward the outer rail 10. In one embodiment, the body 41 is a linearly extending sheet.

The middle rail 30 includes a web 31 and a fixing plate 33 on both sides of the web 31. The web 31 is recessed inwardly from the fixing plate 33 to form a recess 35. The web 31 is provided with a second fastening portion 311 facing the outer rail 10 . The second fastening portion 311 is a convex hull that can be engaged with the first fastening portion 42 . The web 31 defines a bayonet 315, and a second limiting portion 316 is disposed on one side of the bayonet 315. Two parallel middle rail retaining slots 313 are defined in the fixing plate 33.

Referring to FIG. 4 to FIG. 6 , during assembly, the middle portion of the body of the latching member 40 is riveted and fixed to the outer side of the outer rail 10 , so that the first latching portion 42 extends from the latching opening 11 of the outer rail 10 . The two tabs 43 extend from the outer rails of the outer rail 10, and the first limiting portion 45 projects from the limiting opening 15 of the outer rail 10. The middle rail 30 is slidably mounted on the outer rail 10. The inner rail 50 is slidably mounted on the middle rail 30. The middle rail 30 and the inner rail 50 are folded inside the outer rail 10. At this time, the middle rail 30 presses the tab 43 of the latching member 40 and the first limiting portion 45 outward. The two free ends of the body 40 of the latching member 40 are elastically deformed away from the middle rail 30.

Referring to FIG. 7 , when the middle rail 30 and the inner rail 50 are unfolded, the inner rail 50 slides out relative to the middle rail 30 , and the middle rail 30 slides and unfolds relative to the outer rail 10 , and the bayonet 315 of the middle rail 30 . When the first limiting portion 45 of the latching member 40 is moved, the second elastic end 412 of the body 41 elastically recovers, and the first limiting portion 45 extends into the bayonet 315 and the second limiting portion. 316, at this time, the second limiting portion 316 blocks the middle rail 30 from moving in the unfolding direction; at the same time, the tab 43 just moves from the middle rail retaining slot 313 and the retaining slot 313 from the middle rail When the middle portion is extended, the first hook portion 42 is moved to the side of the second hook portion 313 to prevent the middle rail 30 from moving in the folding direction. Therefore, the middle rail 30 is restrained on the outer rail 10 and is prevented from sliding relative to the outer rail 10 in both the folding and unfolding directions.

When the inner rail 50 and the middle rail 30 are folded, the inner rail 50 slides in the folding direction with respect to the middle rail 30. When the inner rail 50 abuts the tab 43 of the latching member 40, the latching member The corresponding end of the body 41 is elastically deformed away from the inner rail 50 and drives the first latching portion 42 to move away from the middle rail 30. The first fastening portion 42 is separated from the second fastening portion 311. The middle rail 30 moves relative to the outer rail 10 in the folding direction. The web 31 of the middle rail 30 abuts against the first limiting portion 45 to disengage the first limiting portion 45 from the bayonet 315. The middle rail 30 and the inner rail 50 are folded relative to the outer rail 10.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
