Abstract: An improved multipoint lock assembly is provided for securing a swinging door in a tightly closed condition. The multipoint lock assembly includes a main actuator cartridge for retracting a plurality of latch pins mounted at vertically spaced positions along a free side edge of the swinging door, in response to rotational movement of indoor and outdoor lever handles. A trigger assembly retains the latch pins in a retracted position in response to lever handle rotation to open the door, and includes a trigger pin for engaging the adjacent door jamb upon door closure to release the latch pins for spring-loaded movement to an advanced position. The advanced latch pins engage ramped strike plates on the door jamb to draw in and tightly retain the closed door against the door jamb. When the latch pins are advanced, a security deadbolt on the main actuator cartridge can be thrown to positively lock the door.

The operator handle is accessible for manual movement to displace a locking cam of the cam unit into releasable locking engagement with a keeper mounted on the sash.

Abstract: An improved lock assembly is provided for high security locking of sliding door particularly such as sliding glass patio doors used in residential dwellings and the like. The improved lock assembly comprises a lock mechanism incorporated into the vertical stile at one side of a sliding door, wherein the lock mechanism is adapted for respective keyed and keyless operation from opposite sides of the door for displacing dual latch members toward and away from each other between locked and unlocked positions. In the locked position, the dual latch members engage a latch keeper on the adjacent door jamb for positively locking the door against unauthorized entry. The lock mechanism is conveniently integrated into a compact cartridge for facilitated mounting into a hollow extruded metal stile. In addition, the lock mechanism may include internal tumblers designed to resist keyless unlocking from the outdoor side of the door.
