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. When the deadbolt is thrown, a panic release mechanism permits retraction of the deadbolt and latch pins in response to rotation of the indoor lever handle, but not in response to rotation of the outdoor lever handle.

Cette invention concerne un dispositif de verrouillage multipoint servant à fermer solidement une porte battante. Le dispositif comprend un mécanisme de commande principal sous forme de cartouche servant à escamoter une série de goupilles de verrouillage espacées verticalement le long du chant libre de la porte, sous l'impulsion du mouvement de rotation des poignées extérieure et intérieure de ladite porte. Un mécanisme à détente maintient les goupilles en position escamotée lorsque les poignées sont tournées en position d'ouverture. Celui-ci comporte un déclencheur qui, au contact du montant de porte, libère les goupilles qui s'avancent, poussées par un ressort, en position de verrouillage. Les goupilles ainsi libérées passent sur une rampe des gâches correspondantes pour tirer et maintenir la porte en position de fermeture étanche contre le montant. Une fois les goupilles sorties, un pêne dormant prévu dans la cartouche susmentionnée peut être actionné pour bloquer la porte en position verrouillée. Lorsque le pêne dormant est actionné, un mécanisme antipanique permet son escamotage et celui des goupilles de verrouillage à la rotation de la poignée intérieure mais non à la rotation de la poignée extérieure.
