A schematic view of the first contact.

1 shows a slide rail assembly including a first rail 10, a second rail 12, a third rail 14, a fixed seat 16, a guide seat 18, a first contact member 20, and A second contact member 22.

The first rail 10 includes an upper wall 24a, a lower wall 24b, and a side wall 26 extending between the upper wall 24a and the lower wall 24b. The upper wall 24a, the lower wall 24b, and the side wall 26 A first channel 28 is defined in common. The side wall 26 has a front end 30a and a front end 30b.

The second rail 12 is slidably connected to the first rail 10, and the second rail 12 also includes an upper wall 32a, a lower wall 32b, and a side wall 34 extendingly connected to the upper wall 32a and the lower wall 32b. The upper wall 32a, the lower wall 32b, and the side wall 34 collectively define a second passage 36. The side wall 34 has an opening 38.

The third rail 14 is slidably coupled to the second rail 12.

The fixing seat 16 is fixedly mounted adjacent to the end 30b of the first rail 10, and The mount 16 is located within the first passage 28 of the first rail 10 and includes a pair of arms 40 defining a gripping space 42.

The guiding seat 18 is a side wall 26 disposed on the first rail 10, and the guiding seat 18 It is located within the first passage 28 of the first rail 10. As shown in FIG. 2, the guiding seat 18 has a pair of longitudinal guiding portions 44 and a blocking portion 46, wherein the pair of longitudinal guiding portions 44 define a guiding path 48 and a guiding inlet 50 and the guiding The paths 48 are open, and each longitudinal guide 44 has a surface 52 located within the guiding path 48 and the guiding inlet 50. In detail, a first width W1 is defined between the surfaces 52 of the pair of longitudinal guides 44 located within the guide path 48. A second width W2 is defined between the surfaces 52 of the pair of longitudinal guides 44 of the guide inlet 50.

As shown in FIG. 3, the first contact 20 is disposed on the side wall of the second rail 12. 34. The first contact member 20 includes a pair of first contact portions 54 and a pair of second contact portions 56 connecting the pair of first contact portions 54, wherein the pair of second contact portions 56 pass through the second rail portion 12 Opening 38. Referring again to FIG. 2, the pair of second contacts 56 corresponds to the guide inlet 50 of the guide seat 18. In a preferred embodiment, the pair of first contacts 54 form a V-shape, and the pair of second contacts 56 have opposing surfaces 58 defining a third width W3 between the pair of surfaces 58 W3 is greater than the first width W1 of the guiding path 48 of the guiding seat 18, but smaller than the second width W2 of the guiding inlet 50 of the guiding seat 18. Preferably, the second contact portion 56 has a slope 57 corresponding to the guide inlet 50 of the guide seat 18, so that the second contact portion 56 is easily guided by the guide seat 18.

The second contact 22 is disposed on the third rail 14, and the second contact 22 includes A pair of side portions 60 and a protruding portion 62, wherein the pair of side portions 60 are the pair of first contact portions 54 corresponding to the first contact member 20. The protruding portion 62 is a clamping space 42 corresponding to the fixing seat 16. Preferably, as shown in FIG. 4, a fourth width W4 is defined between the pair of side portions 60. As shown in FIG. 5, the pair of first contacts 54 of the first contact member 20 define a fifth width W5, and the fifth width W5 is substantially equivalent to the fourth width W4.

FIG. 6 shows the second embodiment of the slide rail assembly of the embodiment of the present invention in a collapsed state, the second The contact member 22 is located between the first contact member 20 and the fixing seat 16 , and the protruding portion 62 of the second contact member 22 is inserted into the clamping space 42 of the fixing seat 16 and is supported by the fixing seat 16 . The pair of arms 40 clamp the protruding portion 62 of the first contact member 22 so that the slide rail assembly can be held in the folded state to prevent the third rail 14 from slipping from the second rail 12 due to the tilting. Out of it.

7 and 8a show that when the third rail 14 is pulled out relative to the first rail 10, In detail, a portion of the third rail 14 is pulled over the front end 30a of the first rail 10, the second contact 22 is detached from the clamping space 42 of the fixing seat 16, and the second contact The member 22 is synchronously pushed against the first contact member 20 such that the second rail 12 is synchronously displaced as the third rail 14 is pulled out.

FIG. 8b shows that the first contact 20 is displaced by the second contact 22 To the guide seat 18, a portion of the second contact portion 56 of the first contact member 20 enters the guide inlet 50 of the guide seat 18. Referring to FIG. 2 and FIG. 3, the third width W3 between the pair of second contact portions 56 is greater than the first width W1 of the guiding path 48 of the guiding seat 18, but smaller than the guiding of the guiding seat 18. The second width W2 of the introduction port 50, therefore, as the first contact member 20 is continuously pushed and displaced by the second contact member 22 to a predetermined position, FIG. 9a further shows that the first contact member 20 will pass through the guide. The guiding inlet 50 of the seat 18 enters into the guiding path 48 of the guiding seat 18 and abuts the guiding seat 18 The pair of second contact portions 56 of the first contact member 20 are also guided by the guiding path 48 of the guiding seat 18 to be pressed and displaced toward each other, so that the first contact member 20 is pressed. The pair of first contact portions 54 are displaced in the opposite direction.

9a and 10 show the second contact 22 when the third rail 14 is continuously pulled out. Since the pair of side portions 60 no longer contact the pair of first contact portions 54 of the first contact member 20, the second rail 12 is no longer synchronously displaced with the third rail 14, and the second portion The rail 12 stays at the guiding seat 18 by means of the first contact 20, and the second rail 12 is stopped relative to the first rail 10 to a position. Therefore, the third rail 14 can still be pulled out relative to the second rail 12.

When the third rail 14 is folded from a deployed position relative to the first rail 10, the third The rail 14 is displaced relative to the second rail 12 until after the second contact 22 passes over the first contact 20, as shown in FIG. 11, when the second rail 12 is continuously pushed and folded relative to the first rail 10 The first contact member 20 is detached from the guiding seat 18, and when the third rail 14 and the second rail 12 are completely folded relative to the first rail 10, the state shown in FIG. 6 is restored.

While the present invention has been disclosed in the foregoing preferred embodiments, it is not intended to limit the scope of the invention, and the scope of the invention is defined by the scope of the appended claims.
