first embodiment

[0023]Referring to FIG. 1, the drawer slide rail assembly in the present invention include a first rail 10, a second rail 12 movably connected to the first rail 10, and a drawer adjusting mechanism 14. The first rail 10 is configured to be mounted to a cabinet (not shown), and the second rail 12 is configured to be mounted to a drawer (not shown). The drawer adjusting mechanism 14 is configured for adjusting the drawer and keeping it in a predetermined horizontal position relative to the first rail 10 so that the drawer can be pulled out of or pushed back into the cabinet smoothly.

[0024]As shown in FIG. 2, the second rail 12 has a generally C-shaped cross-section and includes a pair of sidewalls 16 and a main wall 18 extending between the sidewalls 16. The main wall 18 includes a first projection 20a, a second projection 20b, a mounting portion 22, a first connecting portion 24, and a second connecting portion 26. The mounting portion 22, the first connecting portion 24, and the sec...

second embodiment

[0030]FIG. 5 and FIG. 6 show the drawer adjusting mechanism 200 in the present invention, wherein the drawer adjusting mechanism 200 includes a pair of supporting members 202 connecting a movable member 204 to the second rail 12. In more detail, the movable member 204 has a pair of slots 206 each configured for movably connecting with one supporting member 202. Moreover, each slot 206 is so oriented as to be generally perpendicular to either sidewall 16 of the second rail 12. The drawer adjusting mechanism 200 further includes an adjusting member 208, and the adjusting member 208 includes a cam 210 and a shaft 212 eccentrically connected to the cam 210. At least a portion of the cam 210 presses against the movable member 204, and the shaft 212 passes through the movable member 204 and is connected to the second rail 12 so that, by means of the adjusting member 208, the movable member 204 can be adjusted relative to the supporting members 202 and thus be displaced upward or downward ...

third embodiment

[0031]FIG. 7 and FIG. 8 show the drawer adjusting mechanism 300 in the present invention, wherein the drawer adjusting mechanism 300 includes a pair of supporting members 302 connecting a movable member 304 to the second rail 12. More specifically, the movable member 304 has a slot 306 for movably connecting with the supporting members 302. The slot 306 is so oriented as to be generally perpendicular to either sidewall 16 of the second rail 12. The drawer adjusting mechanism 300 further includes an adjusting member 308, and the adjusting member 308 includes a cam 310 and a shaft 312 eccentrically connected to the cam 310. At least a portion of the cam 310 presses against the movable member 304, and the shaft 312 passes through the movable member 304 and is connected to the second rail 12 so that, by means of the adjusting member 308, the movable member 304 can be adjusted relative to the supporting members 302 and thus be displaced upward or downward relative to the second rail 12 c...

Abstract

A drawer slide rail assembly includes movably connected first and second rails, a movable member, a supporting member, and an adjusting member. The movable member has a mounting hole corresponding to a mounting portion of the second rail and is linearly movably mounted to the second rail via the supporting member. The adjusting member includes a cam with an eccentric shaft. The cam at least partially presses against the movable member. The shaft extends through the movable member and is connected to the second rail. The second rail can be mounted to a drawer via a connecter which also connects the movable member and the second rail. The drawer is adjustable in position relative to the second rail by the adjusting member.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a drawer slide rail assembly which includes a drawer adjusting mechanism to facilitate the adjustment of the relative position of a drawer mounted to the drawer slide rail assembly.BACKGROUND OF THE INVENTION[0002]Structures of drawer height adjusting devices are disclosed, for example, in U.S. Pat. No. 6,923,518 B2, granted to Kim; US Patent Application Publication No. 2008 / 0018213 A1 of Chen et al.; and U.S. Pat. No. 4,842,422, granted to Nelson.[0003]In the prior art disclosed in the patent granted to Kim and the patent application of Chen et al., a drawer is connected to one end of an adjusting element (adjustment member 57, adjusting lever 2) configured for and pivotally connected to a rail, and the vertical position of the drawer can be adjusted by rotating the adjusting element. However, as the drawer is adjusted along a curved path of rotation of the adjusting element, forward or backward displacement of the drawer...
