Abstract

L'invention concerne un dispositif de porte palière qui est destiné à un ascenseur et qui permet d'améliorer l'efficacité de travail pour limiter le mouvement de la porte palière dans la direction de fermeture de porte. Ce dispositif de porte palière pour un ascenseur comprend une porte palière, un élément de réception de verrou disposé dans une paroi d'une cage d'ascenseur, ainsi qu'un verrou disposé dans la porte palière et accroché sur l'élément de réception de verrou, limitant ainsi le mouvement de la porte palière dans la direction de fermeture de porte. Lorsque la porte palière se déplace avec une porte de cabine, la porte palière se déplace entre une position fermée de porte, où la porte palière est fermée, et une position ouverte de porte, où la porte palière est ouverte. Lorsque la porte palière se déplace séparément de la porte de cabine, la porte palière se déplace entre la position fermée de porte et une position de verrouillage ouverte de porte, où la porte palière s'est déplacée de la position ouverte de porte par une distance définie précédemment dans la direction d'ouverture de porte. Lorsque la porte palière est dans la position de verrouillage ouverte de porte, le verrou est accroché sur l'élément de réception de verrou.
