ABSTRACT:
The assembly includes a door with rotatable door handle connected thereto, and a primary locking mechanism on a door hinged for opening and closing in a frame disposed in an entry way. The door includes a handle hub lock mechanism, including an actuator connected to a biasing force reversal mechanism for causing locking of the handle in a given position. The biasing mechanism preferably includes an actuator extendible from the leading door edge towards and alternatively into a recess in the door jamb. A lost-motion mechanism interconnects the actuator and the force reversal mechanism. The actuator normally extends outwardly from the door edge a significantly greater distance than the distance between the strike plate and the door edge. An adjustible connector mechanism interconnects the actuator and the primary door latch which causes both to move in tandem, whereby closure of the door causes the strike plate to cam the latch which, in turn, moves the actuator and allows the recessed actuator to clear the strike plate as the door is closed.
