ABSTRACT:
An upright storage cabinet has a lock assembly which operates a vertically movable lock bar to simultaneously lock all drawers of the cabinet. The lock assembly includes a rotatable cam body which has a resiliently deflectable cam that projects radially therefrom. The cam body is rotatable between a locked position wherein the cam rotates a drive element to vertically displace the lock bar into engagement with the drawers, and an unlocked position wherein the cam allows the drive shaft to return to an initial position which disengages the lock bar from the drawers. The cam generates a driving force on the drive shaft during rotation of the cam body and is also resiliently deflectable to accommodate dimensional variations which varies the radial position of the drive shaft relative to the drive element.
