CA 2371426

A multipoint lock assembly includes a central latch (20) and at least one remote latch (24) vertically spaced therefrom. The retraction of all the latches is controlled by a central latch driving mechanism (18) in response to a manual operation either of an exterior thumb-operated latch lever (32) or of an interior doorknob (48). A deadbolt (30) is also located proximate the central latch (20). The deadbolt (30) is controlled either by an externally accessed cylinder lock (68) or by a manual rotation of an interior-mounted thumb-turn (70). While the deadbolt (30) is extended, the thumb-operated latch lever (32) and the doorknob (48) are inoperable. At least one of the latches includes a latch trigger (66). This is tripped when the door is closed, allowing the latch (24) of which it is a part to assume a superextended position. When in this position the latch (24) cannot be forced into its retracted position unless the thumb-operated latch lever (32) or the doorknob (48) has been operated.

L'invention concerne un ensemble verrou multipoint comprenant un loquet central (20) et au moins un loquet à distance (24), espacé du premier dans la direction verticale. La rentrée de tous les loquets est commandée par un mécanisme d'entraînement (18) du loquet central en réaction à l'actionnement manuel d'un levier de loquet (32) extérieur, actionné par le pouce, ou d'une poignée de porte (48) intérieure. Un pêne dormant (30), également situé près du loquet central (20), est commandé soit par une serrure à cylindre (68) à laquelle on accède par l'extérieur, soit par rotation manuelle d'une barrette tournante (70) montée à l'intérieur. Lorsque le pêne dormant (30) est étendu, le levier de loquet (32) et la poignée (48) de porte ne peuvent être actionnés. Au moins un des loquets comprend un pêne de fermeture (66) qui est enclenché lorsque la porte est fermée, ce qui permet au loquet (24), dont il fait partie, de prendre une position trop étendue. Lorsque le loquet (24) se trouve dans une telle position, on ne peut le forcer à rentrer, à moins que le levier de loquet (32) ou la poignée (48) de porte soient actionnés.
