ABSTRACT:
A drawer slide structure includes a pair of slide mechanisms supporting the drawer in a cabinet, each mechanism including a pair of vertically spaced telescoping inner and outer relatively slidable channels, the inner channels being rigidly interconnected, the lower outer channel being mounted to the cabinet and the upper channel supporting the drawer. An angle member is secured to the drawer side wall and rests on the upper outer channel and is coupled thereto by a resilient latch element mounted on the upper outer channel front end and releasably engaging a front opening in the angle member horizontal web. Intercoupling is effected merely by lowering the drawer onto the channel member and uncoupling is effected merely by pressing the latch element and raising the drawer front end. A resilient loop depends from the latch element and frictionally engages the lower outer channel in the slide contracted position to prevent inadvertent withdrawal of the drawer. Balls are retained between each pair of channels by a nylon ball retainer including resiliently memory expanding ball holding wings disposed between the channel race defining flanges.
