ABSTRACT:
A storage cabinet with a plurality of drawers has an interlocking mechanism which prevents more than one drawer being opened at any time. A vertical U-shaped support rail is located in the back of the cabinet, and vertical locking bars are disposed therein. Each locking bar pivots between two angular positions, and at least one shuttle mounted in the support rail confines the locking bars to a restricted range of pivoting, and requires that their pivoting be simultaneous. A spring bias on the shuttle forces the locking bars into one of two spring-biased pivot positions. In a first position, all the drawers are closed, and are free to be opened. The opening of a drawer causes a camplate attached to the drawer to shift the locking bars from the first pivot position to the second pivot position. In the second position, the unopened drawers are locked due to the obstruction of the camplates of the unopened drawers by one of the locking bars. Upon the opened drawer being closed, the camplate of the open drawer engages the locking bars and moves them back to the first pivot position, thereby removing the obstruction. Side supports of the camplates reinforce the stress on the support rail caused by deflection of one of the locking bars when a drawer is pulled on while in the locked position. A single cabinet locking mechanism and a gang-locking mechanism are also provided to allow manual cabinet locking.
