ABSTRACT:
An interior door latch assembly whereby a door is held in a closed position by a spring-loaded latch keeper pivoted within its own keeper housing which is located in the door frame, the keeper being biased outwardly for latching engagement with the lip of a mating carriage housing disposed within the door along the free leading end thereof. The door is opened by slidably moving a spring-biased carriage lever which extends outwardly from both sides of the door, the lever having a pivoted arm operably coupled thereto. The pivot arm forces the spring-biased keeper beyond the lip of the carriage housing, thereby disengaging the keeper therefrom and allowing the door to open. The improved assembly is installed by cutting a V notch in the frame end of the door to receive the carriage housing, and boring a corresponding shallow cavity into the door frame wherein the keeper housing is received therein. A large drilled hole in the door is not required.
