ABSTRACT:
A vandal-resistant torque sensitive release mechanism is disclosed for coupling and decoupling an actuating handle to a lock mechanism. The torque sensitive release mechanism is disclosed is in the form of a slip-clutch, with the rotational movement of the slip clutch being limited when excessive force is applied to prevent the actuating handle from moving to a position where it would interfere with the subsequent desired opening of the door.
