That is, the urging force of the locking holding member 39 of the car-side locking mechanism 30 is set smaller than the urging force of the locking holding member 239 of the building-side locking mechanism 230.

Abstract

L'invention a pour objet de produire un dispositif d'ascenseur dans lequel un verrou de porte de cabine peut être libéré même lorsqu'un corps étranger est pris en sandwich uniquement entre des portes palières. Pour ce faire, selon l'invention, une came de levage fixe dans ce dispositif d'ascenseur est disposée de telle sorte qu'un espace entre une pièce de mise en prise côté logement de porte de cabine et une pièce de mise en prise côté butoir de porte de cabine ne s'ouvre pas avant que l'espace entre les portes palières, lorsque les portes sont fermées, devient égal à la valeur numérique (L3-L1-L2), dérivée par soustraction d'un espace (espace L1) entre un rouleau de mise en prise côté bâtiment et la pièce de mise en prise côté butoir de porte de cabine et une course (espace L2) pour libérer le verrou de porte de cabine, depuis un espace (espace L3) entre un élément de crochet côté verrouillage et un élément de crochet côté fixation lorsque toutes les portes sont fermées. La came de levage fixe présente la forme d'un C inversé.
