Abstract

L’invention a pour objet un dispositif de synchronisation pour porte de cabine d’ascenseur dans lequel la porte de la cabine et une porte palière sont alignées et s’ouvrent et se ferment dans une plage d’alignements définie où la porte de la cabine est alignée avec la porte palière sur un palier tandis que l’ouverture de la porte de la cabine est interrompue lorsqu’elle se produit dans une plage hors de la plage d’alignements définie où la porte de la cabine et la porte palière ne sont pas alignées entre des paliers. Un mécanisme de levier (7) stoppant l’ouverture de la porte de la cabine est monté dans la porte de la cabine, un élément d’engagement (11) en prise avec le mécanisme de levier (7) est placé dans la cabine (1) et une came limitant la rotation du mécanisme de levier (7) est montée dans la porte palière. L’ouverture de la porte de la cabine est interrompue mécaniquement dans la plage où la porte de la cabine n’est pas alignée avec la porte palière. Comme la came limitant la rotation du mécanisme de levier (7) pour interrompre l’ouverture de la porte de la cabine est installée dans la porte palière, son montage peut être facilité et le degré de liberté de son point de montage peut être accru en optant pour un mécanisme de levier (7) interrompant l’ouverture de la porte de la cabine en deux de type arbre (8, 9).
