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, hand 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.

L'ensemble serrure à mortaiser multipoint comprend une têtière étendue affleurant le bord d'une porte et à laquelle est raccordée une serrure à mortaiser, et une paire de mécanismes de verrouillage à pêne à crochet fixés à la têtière, au-dessus et au-dessous de la serrure à mortaiser. Un actionneur allongé, qui est de préférence une tige plate montée coulissante à l'arrière de la têtière, agit de façon à étendre et rétracter les pênes à crochet de manière synchrone avec un pêne dormant de la serrure à mortaiser. L'actionneur est raccordé entre un bras du pêne dormant de la serrure à mortaiser qui commande le pêne dormant et les mécanismes de verrouillage à pêne à crochet. Le bras d'un pêne dormant est commandé de manière traditionnelle par une clé ou un loquet à poussier, et sa forme permet d'actionner d'une main l'ensemble serrure à mortaiser multipoint.
