Detailed Description of the Invention

[0015] Referring to FIG. 1, the drawer slide rail assembly in the first embodiment of 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.

[0016] 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 second connecting portion 26 are located between the first projection 20a and the second projection 20b. In this embodiment, the mounting portion 22, the first connecting portion 24, and the second connecting portion 26 are all provided in the form of a hole, but these three portions are by no means limited to this form. In a preferred embodiment, the second rail 12 has another mounting portion 23, such as a slot spaced from the mounting portion 22 by a predetermined distance. The mounting portion 22 is adjacent to an end of the main wall 18 of the second rail 12.

[0017] As shown in FIG. 3A, the drawer adjusting mechanism 14 is mounted on the main wall 18 of the second rail 12. The drawer adjusting mechanism 14 includes a movable member 28, a supporting member 30, and an adjusting member 32.

[0018] The movable member 28 is linearly movably mounted on the main wall 18 of the second rail 12 and is located between the first projection 20a and the second projection 20b of the second rail 12. The first projection 20a and the second projection 20b of the second rail 12 serve to guide and thereby enable the movable member 28 to displace linearly relative to the second rail 12. More specifically, the movable member 28 has a first part 34, a second part 36 extending from and at an angle to the first part 34, a mounting hole 38, a first hole 40, and a second hole 42. Preferably, a portion of the second part 36 is movably located in the mounting portion 22 of the second rail 12 and can therefore be displaced to a limited extent within the mounting portion 22. The mounting hole 38 is located in the second part 36 and corresponds to the mounting portion 22 of the second rail 12. The first hole 40 and the second hole 42 are located in the first part 34 and correspond to the first connecting portion 24 and the second connecting portion 26 of the second rail 12 respectively. The distance between the two lateral sides of the first hole 40 is defined as width w1, and the distance between the top side and the bottom side of the first hole 40 is defined as height h1. The second hole 42 has a hole wall 44.

[0019] At least a portion of the supporting member 30 extends through the first hole 40 of the movable member 28 and is connected to the first connecting portion 24 of the second rail 12. Thus, the supporting member 30 connects the movable member 28 to the second rail 12. More specifically, the at least a portion of the supporting member 30 has a width w2 and a height h2, as shown in FIG. 3B. The width w2 is generally equal to the width w1, but the height h2 is less than the height h1; consequently, a path is formed, allowing the movable member 28 to displace linearly along the path relative to the supporting member 30.

[0020] The adjusting member 32 includes a cam 46 and a shaft 48 eccentrically connected to the cam 46. At least a portion of the cam 46 presses against the hole wall 44 of the second hole 42 of the movable member 28. The shaft 48 passes through the second hole 42 of the movable member 28 and is connected to the second connecting portion 26 of the second rail 12. When the adjusting member 32 is rotated, the movable member 28 is pushed by the cam 46 and is hence displaced upward or downward relative to the supporting member 30. Preferably, the cam 46 has a tool portion 50, such as an engaging groove in which a corresponding tool (e.g., a screwdriver) can be inserted to facilitate rotation of the adjusting member 32.

[0021] In FIG. 4, the second rail 12 has been mounted to a side of a drawer 52. More specifically, the second rail 12 is mounted to the drawer 52 by a connector 54 a portion of which extends through the mounting hole 38 of the movable member 28 and the mounting portion 22 of the second rail 12. In addition, the mounting portion 23 (see FIG. 2) of the second rail 12 is connected to the drawer 52 by a fixing element (not shown). Therefore, should an inclination angle α be formed between the second rail 12 and the drawer 52 after assembly, the adjusting member 32 can be rotated with a tool to displace the movable member 28 linearly relative to the second rail 12, thereby eliminating the undesirable angle between the second rail 12 and the drawer 52, allowing the drawer 52 to by pulled out of or pushed back into a cabinet in a smooth manner. The foregoing design is particularly useful when a plurality of drawers 52 are vertically arranged in a cabinet, for the gap or angle between each two adjacent drawers 52 can be fine-tuned and corrected as needed.

[0022] FIG. 5 and FIG. 6 show the drawer adjusting mechanism 200 in the second embodiment of 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 relative to the second rail 12 conveniently.

[0023] FIG. 7 and FIG. 8 show the drawer adjusting mechanism 300 in the third embodiment of 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 conveniently.
