ABSTRACT:
A storage cabinet is disclosed having a frame and a drawer movable with respect to the frame and a locking system. The locking system includes an input device having an output link movable along a path between a raised position and a lowered position and a lock blade (or coupling link) coupled to the output link of the input device, an output end and a fulcrum point. The locking system also has a lockbar coupled to the lock blade, a first locking element associated with the lockbar, and a second locking element associated with the drawer to be engaged by the first locking element. When the input device drives the output link to the raised position, the input end of the lock blade is raised and the lock blade pivots about the fulcrum point so that the output end of the lock blade is lowered and the lockbar disengages the first locking element from the second locking element. When the input device drives the output link to the lowered position, the input end of the lock blade is lowered and the lock blade pivots about the fulcrum point so that the output end of the lock blade is raised and the lockbar engages the first locking element with the second locking element. The locking system may include a pair of lockbars, each lockbar coupled to a coupling link. A pivot point for the fulcrum point of each coupling link is associated with the frame.
