Multipoint mortise lock

A multipoint mortise lock assembly for mounting in an edge of a door comprising:

• an elongated face piece for mounting to the edge of the door;
• a mortise case connected to the face piece;
• first and second hook bolt latch mechanisms mounted to the face piece at points above and below the mortise case, the latch mechanisms including corresponding first and second hook bolts mounted in the latch mechanisms for motion between a latched position and an unlatched position, the hook bolts extending outward from the face piece in the latched position;
• a deadbolt slidably mounted in the mortise case for motion between an extended position and a retracted position, the deadbolt extending outward from the face piece in the extended position;
• a deadbolt arm mounted in the mortise case for driving the deadbolt, the deadbolt arm and deadbolt being drivable by a lock arm on a cylinder lock to move the deadbolt between the extended position and the retracted position;
• a link connected to the deadbolt arm;
• an elongated actuator slidably mounted to face piece and operably connected to the first and second hook bolt latch mechanisms and the link, the elongated actuator moving the first and second hook bolts to the latched position when the deadbolt arm drives the deadbolt to the extended position.
