ABSTRACT:
A door lock is provided for use with a building wall having a door opening formed by building framing members and in which a door is pivotally mounted and movable between a closed and an open position. The door lock has a locking bolt which is slidably mounted by a slide block to the building framing members on the inside of the wall. A key operated assembly accessible from the outside of the wall is operable to move the locking bolt between a locking position in which a portion of the bolt extends behind the door and thus into the path of the door swing, and a nonlocking position in which the bolt is retracted into the slide block and thus spaced downwardly from the path of the door swing. Since the slide block is mounted to the building framing member, typically a two by four wooden stud, the door lock utilizes the strength of the building itself rather than just the strength of the door or its jamb.
