Abstract

La présente invention a pour objet de réaliser un dispositif d'ascenseur de telle manière que si un opérateur d'entretien effectue un travail sur une cabine, une porte est dressée sur le côté palier au sommet de la cabine de façon à empêcher l'entrée de l'opéateur dans un dispositif de porte palière ou un dispositif de porte de cabine lorsque la cabine monte, ce qui permet ainsi d'empêcher efficacement une partie ou la totalité du corps de l'opérateur d'être prise au piège entre un élément support et le dispositif de porte de cabine à proximité du plafond d'une gaine d'ascenseur. Le dispositif d'ascenseur selon l'invention est équipé : d'un premier élément support qui possède un côté fixé au sommet d'un premier rail de guidage et l'autre côté s'étendant vers le palier ; un deuxième élément support qui possède un côté fixé au sommet d'un deuxième rail de guidage et l'autre côté s'étendant vers le palier ; un troisième élément support qui possède un côté fixé au côté palier du premier élément support et l'autre côté fixé au côté palier du deuxième élément support ; et une porte d'ouverture et de fermeture qui se dresse dans la partie supérieure de la cabine davantage vers le côté opposé au côté palier que le troisième élément support, vue dans un plan de projection vertical, et qui permet à l'opérateur de passer à travers celle-ci lors d'un déplacement entre le palier et une zone de travail située dans la partie supérieure de la cabine.
