ABSTRACT:
A door lock for use with an elongated rod used as an auxiliary holding device in addition to the conventional door lock. The auxiliary door holding rod is actuatable from outside the door by means of a conventional key actuated lock so as to permit the auxiliary safety rod to be moved between locked and unlocked positions from outside the door as well as from inside the door. A lost motion device is incorporated in the connection between the door lock and the rod holder to prevent interference between the lock structure and the internal manual actuation of the rod holder.
