ABSTRACT:
A self-locking electronic lock system is illustrated in association with safe doors having a door locking bolt works manipulated between door open and door locked positions by a door mounted handle. The bolt works includes a link which moves the door bolts and in turn is locked by an electronic lock in accordance with the present disclosure. The elctronic lock has a spring bias bolt normally biased into a locking gate provided on the link and is operated to a withdrawn position by an associated digital input electronic signal generating means. A lost motion connection is provided between an electric motor of the lock and the lock bolt such that the motor withdraws the lock bolt on entry of a correct combination to the digital input means and the lock bolt is biased back into locking engagement with the link gate by operation of an operator closing the safe door and manipulating the door handle to throw the door bolts into engagement with the safe door jamb, the electronic lock bolt automatically locking up with the bolt works link to prevent reopening of the door until the combination is entered again due to the bias of the lock bolt toward the link gate.
