Abstract

A lock mechanism is provided which may actuate both a deadbolt and flush bolts in response to a single lock movement. The mechanism includes a dual element bolt throw and flush bolt actuator, which locks in place in the extended position if the end of the bolt is pressed inwardly. The throw includes a transfer mechanism which translates the horizontal movement of the bolt to vertical movement at the flush bolts. The flush bolts also include a mechanism to limit retraction thereof if the extending end of the flush bolt is exposed to inward directed force. The entire lock mechanism may be actuated by a standard cylindrical lockset having actuating jaws extending therefrom. The lock mechanism case may include an aperture therein, through which the handle housing extends, which aligns the jaws in the handle housing with the rear end of the bolt.
