A combination lock/deadbolt is connected to a push-to-open panic-bar device to operate in response to push-bar operation, thereby withdrawing both the push-bar latchbolt and the deadbolt permitting instantaneous and unrestricted egress from a secured area. To maintain the security of the area from unauthorized entry from outside the secured area, a connection between the push-to-open device and the combination lock/deadbolt assembly is implemented with a lost motion connection. The lost motion device, preferably is a flexible cable transmitting force only in tension, assures that any operation of the combination lock/deadbolt will not effect the security provided by the push-to-open device. Further, the push-to-open device may be provided both with a conventional key cylinder lock and a knob, ever, or thumb lever release on the door exterior. Opening action initiated from outside the door through the knob lever or thumb lever release is mechanically segregated from the cable connection to the combination lock/deadbolt, preventing operation of the push-to-open device from the outside causing operation of the combination lock/deadbolt assembly.

A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a mechanical linkage assembly is driven by the engagement element to unlock a lock-bolt. The mechanical linkage assembly includes a low inertia pivoting cam which interacts with a lock lever of the locking mechanism to move it to an unlocking state. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.

A self-powered electric lock includes a lock bolt and a first engagement element having disengaged and engageable positions. An electric actuator includes an output operative to move the first engagement element to its engageable position. A manually operated rotatable member is operatively coupled to the first engagement element when the first engagement element is in its engageable position. A lock bolt drive mechanism is coupled to the lock bolt and to the first engagement element when the first engagement element is in its engageable position. The movable output moves the first engagement element to its engageable position upon input of correct electronic data. An electricity generator is coupled to the manually operated rotatable member. The electricity powers the electric actuator and an electronic data input device. The manually operated rotatable member is also used to actuate the lock bolt drive mechanism and retract the lock bolt.

A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a manually operated element moves the engagement element to unlock a lock-bolt. In one embodiment, the engagement element is connected to the rotor of a low power, low-friction electric motor having magnetic detents corresponding to the disengaged and engageable positions. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.

Interlocks are described that prevent the bolt of a bolt lock from being displaced to the unlocked position by the use of impact and inertial of the lock parts, heat and the displacement of the cover plate of the lock housing.
