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 transposes 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 ends 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.
