Title: Drawer or filing cabinet lock - all drawers bolted simultaneously at the rear
IPC: E05B/
Filed: 1974-03-26
Abstract: A lock for filing cabinet or other multi drawer cabinet acts through a single lockable bolt at the top and front on all drawers simultaneously. A drawer open at the time of locking can be closed later and the lock will engage. The lock comprises a cylindrical bolt (1), sliding in a casing (2) attached to the cabinet (3).
