Drawer slide assembly having an adjustment mechanism
A drawer slide assembly having an adjustment mechanism includes a slide, an adjusting lever, and a guide block. A first aperture, a pivoting part, and a second aperture are disposed on the slide. The adjusting lever includes a first end, a middle section pivoted to the slide, and a second end. The first end corresponds in position to the first aperture, and the second end corresponds in position to the second aperture. The guide block is pivoted to the second end of the adjusting lever. A protruding portion is disposed to the bottom of the guide block to slide in the second aperture by turning the guide block. The adjusting lever deflects and the first end slides in relation to the first aperture. A fastening member penetrates through the first end to connect to and fine tune for higher or lower of a drawer or similar object.
(a) Field of the Invention
The present invention relates to a drawer slide assembly having an adjustment mechanism, and more particularly, to one that allows fine-tuning of the longitudinal position of the slide in relation to a drawer or deck incorporated to the slide.
(b) Description of the Prior Art
The prior art of adjustment method for a drawer or similar object mounted to a retractable slide is taught in U.S. Pat. Nos. 4,291,929, 6,585,336 B2, and 6,923,518 B2, and Taiwanese Patent No. 1250002 (a patent same as that of U.S. Pat. No. 6,923,518 B2.) Among the cases cited, some require comparatively larger space for assembly (i.e., the combination of worm and worm gear) and others require greater operating force to be applied to wrench an adjustment member, which is much more laborious.
SUMMARY OF THE INVENTIONThe primary purpose of the present invention is to provide a drawer slide assembly having an adjustment mechanism that allows easy adjustment simply by using a hand tool to fine tune the longitudinal position of the slide in relation to a drawer or deck incorporated to the slide.
To achieve the purpose, the present invention includes a slide, an adjusting lever and a guide block. A first aperture, a pivoting part, and a second aperture are disposed on the slide. The adjusting lever comprises a first end, a middle section, and a second end. The middle section is pivoted to the pivoting part of the slide. The first end of the adjusting lever corresponds in position to the first aperture of the slide, and the second end of the adjusting lever corresponds in position to the second aperture of the slide. The guide block is pivoted to the second end of the adjusting lever. A protruding portion is disposed at the bottom of the guide block in relation to the second aperture of the slide. Accordingly, the protruding portion slides in the second aperture by turning the guide block and the adjusting lever defects with its middle section where pivoted to the pivoting part as the axis, while the first end of the adjusting lever slides in relation to the first aperture. Wherein, the protruding portion of the guide block is eccentrically disposed; a locking head is disposed on the top of the guide block; a pivoting hole is disposed in the middle section and the pivoting part of the slide is formed with a hollow tube to penetrate through the pivoting hole for installation; or alternatively a pivoting hole is disposed in the middle section and a through hole is disposed on the slide for a pivot to penetrate through the pivoting hole and to be riveted to the through hole.
The present invention allows easy and laborsaving operation, in compact construction to allow easier mounting onto the slide.
