DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a drawer system 10 which includes a drawer housing 12, a drawer 14, and a pair of slide rail assemblies 16. The slide rail assemblies 16 are mounted between the drawer housing 12 and the drawer 14 so that the drawer 14 can be easily pulled out from or pushed back into the drawer housing 12 by means of the slide rail assemblies 16. In one preferred embodiment, the drawer system 10 further includes a pair of garbage containers 18 mounted in the drawer 14 and may therefore serve as a piece of furniture for storing garbage.
FIG. 2 shows the slide rail assembly 16 in an embodiment of the present invention. The slide rail assembly 16 includes a bracket 20, a fixing base 22, a supporting base 24, and a rail member 26. The bracket 20 is mounted at a first position on the drawer housing 12. The fixing base 22 is mounted at a second position on the drawer housing 12. The supporting base 24 is mounted at a third position on the drawer housing 12 and is configured for supporting the rail member 26. The supporting base 24 is also connected to the fixing base 22. The rail member 26 is mounted between the bracket 20 and the supporting base 24. Preferably, the first position is adjacent to an opening of the drawer housing 12, the second position is on a back panel of the drawer housing 12, and the third position lies between the first position and the second position.
Referring to FIG. 3 and FIG. 4, the rail member 26 includes an upper wall 28 a, a lower wall 28 b, and a sidewall 30 extending and connected between the upper wall 28 a and the lower wall 28 b. The upper wall 28 a, the lower wall 28 b, and the sidewall 30 jointly define a channel 32. The sidewall 30 has a hanging member 34 and an engaging protuberance 36 located close to the hanging member 34. The hanging member 34 is located outside the channel 32. The engaging protuberance 36 has an engaging surface 38 adjacent to the upper wall 28 a. More specifically, the hanging member 34 has a connecting portion 341 and a fastening portion 342 connected to the connecting portion 341. The connecting portion 341 substantially extends from the sidewall 30 of the rail member 26. The fastening portion 342 is spaced apart from the inner side of the sidewall 30 of the rail member 26 by a predetermined first distance d1.
The bracket 20 includes a first arm 40, a second arm 42, and a body 44 extending and connected between the first arm 40 and the second arm 42. The first arm 40 has a bent section 46 and a supporting section 48 extending from and connected to the bent section 46. The supporting section 48 corresponds in position to the upper wall 28 a of the rail member 26 and is configured for supporting the upper wall 28 a of the rail member 26. The supporting section 48 has a hole 50. The second arm 42 corresponds in position to the first arm 40. The second arm 42 has a bent section 52, a first supporting section 54 a, a second supporting section 54 b extending substantially perpendicularly from the first supporting section 54 a, and a third supporting section 54 c. The first supporting section 54 a has a hole 56. The second supporting section 54 b corresponds in position to the lower wall 28 b of the rail member 26 and is configured for supporting the lower wall 28 b of the rail member 26. The third supporting section 54 c extends substantially perpendicularly from the second arm 42. The third supporting section 54 c is located close to the second supporting section 54 b and also serves to support the lower wall 28 b of the rail member 26. The body 44 has a positioning hole 58, a first wall 60 a defined by an upper hole wall of the positioning hole 58, a second wall 60 b defined by a lower hole wall of the positioning hole 58, a third wall 60 c defined by a lateral hole wall of the positioning hole 58, and a fourth wall 60 d opposing the third wall 60 c. The body 44 has a thickness t.
To assemble, the hanging member 34 of the rail member 26 is passed through the positioning hole 58 of the bracket 20 and hangs on the second wall 60 b of the bracket 20. As a result, the supporting section 48 of the first arm 40 of the bracket 20 is pressed against the upper wall 28 a of the rail member 26, the second supporting section 54 b of the second arm 42 of the bracket 20 is pressed against the lower wall 28 b of the rail member 26, and the body 44 of the bracket 20 is pressed against the sidewall 30 of the rail member 26, with the engaging surface 38 of the engaging protuberance 36 of the rail member 26 contacting against the first wall 60 a of the bracket 20. Thus, the bracket 20 is securely mounted to the rail member 26 in such a way that the hanging member 34 of the rail member 26 abuts against at least one of the third wall 60 c and the fourth wall 60 d. Referring also to FIG. 5 and FIG. 6, the hanging member 34 is elastically pushed away from the sidewall 30 of the rail member 26 due to the thickness t of the bracket 20. More specifically, the distance between the fastening portion 342 of the hanging member 34 and the inner side of the sidewall 30 of the rail member 26 is increased from the first distance d1 to a second distance d2. The bracket 20 is held in place by the elastic restoring force of the fastening portion 342 of the hanging member 34, and the sidewall 30 of the rail member 26 is thus further pressed against the body 44 of the bracket 20. Consequently, the bracket 20 is mounted even more securely on the rail member 26.
In addition, the supporting base 24 has a fixing plate 62 and a supporting plate 64 extending substantially perpendicularly from the fixing plate 62. The fixing plate 62 has at least one lateral hole 66. Preferably, the fixing plate 62 has a plurality of lateral holes 66, and the rail member 26 has a hook 68. At least a portion of the hook 68 is configured to extend through one of the lateral holes 66 of the fixing plate 62 and press against the fixing plate 62.
Referring to FIG. 7, the fixing base 22 has at least one protruding member 70, and the supporting base 24 has a hole 72 at one end. At least one hole wall of the hole 72 is configured to engage with the protruding member 70.
While the present invention has been disclosed via the foregoing preferred embodiments, the embodiments are not intended to restrict the scope of the present invention. The scope of the present invention is defined by the appended claims.
