Patent

CA 2478078

The invention concerns an elevator installation comprising an elevator car (12), which has an elevator car door (13) and is placed inside an elevator shaft (10) in a manner that enables it to be vertically displaced. The elevator installation also comprises shaft doors (11), each having at least one door leaf and provided with an automatically latching shaft door latch (18) for latching the door leaf when the door leaf is located in its closed position. The shaft door latch (18) can be unlatched by the elevator car (12). The elevator installation has a non-contacting sensor means (15, 19) that makes it possible to detect, from the elevator car (12), whether the shaft door latch (18) and the door leaf of the shaft doors (11) are located in their correct latching position, whereby this sensor means (15, 19) can be connected to the elevator control (16) directly or via a separate safety monitoring system.

L'invention concerne un système d'ascenseur comportant une cabine d'ascenseur (12) présentant une porte de cabine et logée de façon à coulisser verticalement dans une cage d'ascenseur (10). Ledit système d'ascenseur comporte des portes de cage (11) présentant respectivement au moins un battant de porte et pourvues d'un verrou de porte de cage (18) destiné à verrouiller automatiquement les battants de porte lorsque ceux-ci se trouvent en position fermée. Ledit verrou (18) peut être déverrouillé par la cabine d'ascenseur (12). Le système d'ascenseur selon l'invention comporte un capteur sans contact (15, 19) permettant de reconnaître, à partir de la cabine d'ascenseur, si le verrou (18) et les battants de la porte de cage (11) se trouvent dans leur position de verrouillage adéquate, ledit capteur (15, 19) pouvant être relié directement à la commande d'ascenseur (16) ou par l'intermédiaire d'un système de contrôle de sécurité séparé.
