ABSTRACT:
A quick release door lock is disclosed which includes a unitary body of thin, flat, hardened steel. The body terminates at one end in an integral tongue and at the other in an integral bent flange. A unitary, generally U-shaped slide is movable along the body between door engaging and door releasing positions in response to the movements of an operating rod. The operating rod is reciprocal and rotatable through the flange and is provided with an unthreaded adjusting section and a threaded securing section. The threaded section is designed with a double lead special thread to provide increased linear movement of the slide in response to rotation of the operating rod. The tongue is a removable fit within the door jamb recess and the slide is movable into engagement with the door to secure the door at the jamb between the body tongue and a pressure face of the slide.
