Abstract
An interlock assembly for use with two or more vertically arranged drawers mounted on telescopic slides in a housing such as a cabinet so as to prevent the extension of a drawer once another drawer is opened. The interlocking system interfaces with the stationary members of vertically arranged slides attached to the cabinet. A pair of opposing upper and lower actuator followers are slidably and transversely fitted near the front of the stationary members so that movement of one actuator follower toward the other, displaces the other. A rod connects the upper actuator follower of one slide with the lower actuator follower of a slide directly above it. An actuator is connected to the front ends of the telescopic members of the slides. As a telescopic member is extended, the actuator of that slide makes contact and displaces the upper actuator follower of the slide which results in the upper displacement of the lower actuator followers of the slides directly above the extended slide. The extended slide also prevents the upward displacement of the upper actuator followers of all the slides directly below it. Consequently, all actuator followers block the path of their respective telescopic members precluding their extension.
