ABSTRACT:
An interlock mechanism is provided for furniture units and the like of the type having two or more drawers, and functions to permit only one of the drawers to be opened at any given time, so as to avoid tipping, etc. The interlock includes a plurality of blocks slidably mounted in a vertical guide, with an actuator provided for each drawer. Each actuator comprises an arm having an upper portion pivotally mounted to the guide, and a lower portion with a notch shaped to selectively engage a pin on the associated drawer, such that closing and opening the drawer rotates the arm between corresponding unlocked and locked positions. Each actuator also includes a wedge pivotally connected with the lower portion of the arm, and slidably supported on the guide to reciprocate inbetween adjacent blocks when the associated drawer is opened, so as to lock closed all remaining drawers. Preferably, the vertical guide is formed in a unique, upright stiffener channel in the case, so as to maximize the lateral space available for the drawers.
