Abstract

Est divulgué un système de verrouillage (100) pour une porte de cabine d'ascenseur d'un ascenseur à vide pneumatique (200). Le système de verrouillage comprend un commutateur de contact (102), un verrou de porte (104) et un câble métallique (106). Le commutateur de contact est positionné à l'intérieur d'un montant de rail de guidage (213) et est en contact avec un cadre de porte (112) lorsque la porte est fermée, et le commutateur de contact est éloigné du cadre de porte lorsque la porte est au niveau du palier. Le verrou de porte est en prise avec le cadre de porte et conçu pour être en contact avec le commutateur de contact. Le câble métallique est conçu pour recevoir un signal de commande provenant d'un dispositif de commande (108) pour activer la cabine d'ascenseur (220) dans une direction vers le haut pour libérer le verrou de porte pendant l'atterrissage de cabine d'ascenseur et l'état ouvert de porte et libérer le verrou de porte partiellement par l'activation dans une direction vers le haut.
