A multipoint mortise lock assembly includes an extended face piece mounted flush along the edge of a door, a mortise lock connected to the face piece, and a pair of hook bolt latch mechanisms mounted to the face piece above and below the mortise lock. An elongated actuator, which is preferably a flat rod slidingly mounted to the back of the face piece, acts to extend and retract the hook bolts in synchronism with a deadbolt in the mortise lock. The actuator is connected between a deadbolt arm in the mortise lock, which drives the deadbolt, and the hook bolt latch mechanisms. The deadbolt arm is driven conventionally, such as by a key or a thumb latch, and the design allows one hand operation of the multipoint mortise lock assembly.

[ Thus, having described the invention, what is claimed is:] [1.]1. 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;at least one latch mechanism mounted to the face piece at a distance from the mortise case, the latch mechanism including a latching bolt mounted in the latch mechanism for motion between a latched position and an unlatched position, the latching bolt extending outward from the face piece in the latched position;a deadbolt movably 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;at least one elongated actuator connected between the at least one latch mechanism and the deadbolt arm, the elongated actuator moving the latching bolt to the latched position whenever the deadbolt arm drives the deadbolt to the extended position.
