ABSTRACT:
A door lock assembly is provided for secure multipoint locking of a door. The lock assembly comprises a main lock cartridge in combination with one or more remote secondary lock cartridges mounted at one side edge of a door, with the main lock cartridge having an actuator for manipulating a plurality of lock members. In one preferred form for use with a hinged or swinging door, the lock members comprise a plurality of latch bolts movable to a first extended position for normal door latching, or to a second and further extended position to function as multiple deadbolts. In an alternate preferred form for use with a sliding door, the lock members comprise headed latch pins for engaging keeper plates on the adjacent door jamb. In either embodiment, the door jamb may comprise the adjacent side edge of a second or semi-active door in a double door entry set, wherein the second door desirably includes a header-sill lock assembly which is maintained in a positively locked condition unless the adjacent door is opened.
