ABSTRACT:
A portable auxiliary locking device for securing an inwardly opening door of a room or building against unauthorized entry is disclosed. The locking device includes a threaded rod which terminates in an axially extending plate region having a hook-like flange formed at the distal end thereof. The threaded rod passes coaxially through a central opening within a tubular body member having an end face that is configured for abutment with the inner surface of the door. A locking barrel, rotatably interconnected with the second end of the body member, includes a quick-release latch that is spring-loaded into engagement with the threaded rod. In operation, the door is closed with the hook-like flange extending into the opening within the strike plate of the door frame and the threaded rod extending inwardly into the room that is to be secured. The quick-release latch is then depressed and the body member slid into abutment with the surface of the door. The locking barrel is then rotated to clamp the door in the closed position.
