ABSTRACT:
A lock for an interlock mechanism that prevents the opening of more than one filing cabinet drawer at a time. The interlock mechanism comprises a fixed-length channel having at least one movable block and at least two wedges. When a drawer is opened, one of the wedges is moved, thereby filling the channel and preventing the opening of another drawer. The lock selectively prevents the wedges from moving into the channel when all of the drawers are closed, thereby locking all of the drawers in the filing cabinet in a closed position.
