Abstract: A bracket assembly includes a first bracket having a plurality of spaced apart anchor members extending outward therefrom for insertion into a plurality of corresponding apertures in a vertical member of a wall panel, and a second bracket having a plurality of spaced apart anchor members extending outward therefrom for insertion into a plurality of corresponding apertures in the vertical member. The anchor members are adapted to cooperate with the vertical member to restrain the corresponding bracket from horizontal movement. Locking means are adapted to move one of said brackets relative to the other such that the anchor members cooperate with the vertical member to secure the bracket assembly thereto.

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.
