Patent ID: 8381558

Claim:
An institutional door lock mechanism comprising: a hollow, elongated and columnar door strike jamb configured to attach to and extend along an exterior vertical surface of a door frame on the side thereof opposite one or more hinges of a door that is coupled with the door frame, the jamb including a catch-extension/retraction mechanism therein, the catch-extension/retraction mechanism including an alternately extendable and retractable catch; a fronting plate configured for mounting to a planar exterior surface of the door adjacent the door strike jamb, the fronting plate having a rear surface and an opposing front surface, wherein the rear surface is configured as a planar expanse suitable to provide a close, contiguous planar-parallel contact with the correspondingly planar exterior surface of the door when the fronting plate is mounted thereto during use; a wire pull handle securely attached to the front surface of the fronting plate and extending outwardly therefrom; a columnar striker plate mechanism likewise securely attached to the fronting plate along an edge thereof and extending outwardly from the front surface thereof, the striker plate mechanism including an aperture formed into an opposite side of the striker plate mechanism relative to the wire pull handle, the aperture further being configured and presented to receive therein the alternately extendable and retractable catch when the catch is extended from the strike jamb during use; wherein the fronting plate, the handle, and the columnar striker plate mechanism are configured as a conjoined structure for unitary attachment to the planar surface of the door; and a remotely controllable switch mechanism operatively coupled with the catch-extension/retraction mechanism for operating the same to secure the door in a closed position relative to the frame.
