Patent

CA 2178800

A multipoint lock assembly is provided for securing a sliding door in a tightly closed and locked condition. The multipoint lock assembly comprises a plurality of latch cartridges mounted at vertically spaced positions along a free side edge of a sliding door, wherein the latch cartridges each include a keyhole-shaped latch port and are movable together for engaging headed latch pins mounted on an adjacent door jamb. A main actuator cartridge is mounted on the door for moving the latch cartridges to an unlatched position to permit door movement to an open position in response to rotation of a door handle. A trigger assembly retains the latch cartridges in the unlatched position until the door is closed, at which time the trigger assembly releases the latch cartridges for spring-loaded movement to a latched position engaging the latch pins. A security deadbolt is also provided on the main actuator cartridge and can be thrown when the door is closed for positively locking the door.
