ABSTRACT:
A door lock structure for securement in a longitudinal cavity disposed in a door vertical free edge portion or folding door edge post, or the like. The door lock structure comprises an elongated locking rod supportingly guided in the longitudinal cavity. Each rod has a locking free end extendible above an open end of the bore above a horizontal edge of the door. The rod is normally biased in a retracted position in the cavity, with the rod locking free end disposed inwardly of the horizontal door edge. An external rod displacement element is secured to the rod for displacing the rod and the locking free end outwardly of the horizontal door edge to a locking position. A bolt engaging mechanism is disposed inwardly of the door edge adjacent the rod for engaging the rod when placed in its locking position. A key-operated cam is provided on an inside surface of the door vertical free edge portion for disengaging the rod engaging mechanism from engagement with the rod.
