Abstract
A cammed lever is configured to nest and lock with a cam follower at a recess formed on the cammed lever or the cam follower. Upon rotation of the lever, the cam follower and the cammed lever are disengaged at the recess to form a gap when the cammed lever is rotated upon outward movement of a drawer or drawer slide. The lock assembly includes the cammed lever and cam follower in a stacked array for use in a storage unit having multiple drawers. Preferably, only one drawer is permitted to open in the stacked array. The cammed lever, when unlocked, is permitted to rotate between the open and closed positions. When locked, the cam follower prevents rotation of the cammed lever to an open position. An optional sliding bracket is provided for added security when the drawers are locked.
