Abstract

L'invention concerne un dispositif de commande pour un ascenseur qui permet de réduire le temps requis pour une cage pour se déplacer vers une position d'évacuation. Le dispositif de commande pour l'ascenseur comprend un moyen de détection de position de cage permettant de détecter la position de la cage de l'ascenseur, un moyen de détection de sinistre permettant de détecter un sinistre subi par l'ascenseur, et un moyen de commande de fonctionnement permettant d'amener la cage dans un état d'arrêt d'urgence et d'amener ensuite la cage à se déplacer vers la position d'évacuation lorsque le sinistre est détecté. Le moyen de commande de fonctionnement amène la cage à passer à côté d'un poids et à se déplacer vers la position d'évacuation au moment du sinistre, la position d'arrêt d'urgence de la cage de l'ascenseur étant située sur un côté parmi le côté supérieur et le côté inférieur depuis une position intermédiaire au niveau de laquelle la cage et le poids passent l'un à côté de l'autre lorsque la cage et le poids sont levés et abaissés, et la position d'évacuation près de la position d'arrêt d'urgence de la cage étant située sur l'autre côté parmi le côté supérieur et le côté inférieur depuis la position intermédiaire.
