Abstract: An electronic lock employs an electronic latch for operating the lock bolt. The lock utilizes a flexible member linked between a portion of the lock bolt and a solenoid device. Upon retraction of a solenoid driver, the flexible member pulls the deadlocking lever for latch retraction. When the flexible member is released by the driver, the bolt can extend for a subsequent opening.
Abstract: An electronic lock mechanism includes a solenoid driven actuator and a cam actuator ring. The cam ring interfaces with both the latch of a door lock and the door lock key cylinder. With this interfacing, the door latch can be independently operated by one of the key cylinder, the cam actuator ring or a door lock push bar or paddle. With this independent operation, the ability to open a door can be maintained during power or lock mechanism failures for purpose of egress from the area secured by the door lock.
