ABSTRACT:
A door latch release mechanism has a housing adapted for mounting in a door jamb, a striker mounted on a shaft in the housing for pivotal movement between a door lock tongue engagement position and a door lock tongue release position, and a stop mounted in the housing. The stop has a portion capable of contacting the striker so as to latch the striker and prevent pivoting thereof from the door lock tongue engagement position. This portion of the stop is generally semi-circular in cross section. The stop is rotatable on its axis so that rotation of the stop to an effective extent releases the striker.
