ABSTRACT:
A live bolt lock mechanism for a safe door uses a rotatable idler 15 in a middle region of the door. A plurality of live bolts 20 spaced around the door each has a connecting rod 19 joined to the idler 15 at crank locations for operating the live bolts. A handle 25 is mounted between the idler and the opening edge of the door, and a combination lock 30 is mounted beside the idler. An actuator 27 rotated by the handle moves an actuator link 31 connected to the idler for rotating the idler when the handle turns. A lock link 50 mounted on the idler and extending toward the combination lock 30 has a projection disposed adjacent the combination lock to block the lock link and idler from movement unless a combination for the lock is fulfilled.
