Abstract

Selon l'invention, un rail de guidage du dispositif d'ascenseur comprend un premier rail et un second rail qui se raccordent verticalement. Le premier rail et le second rail comportent respectivement une première partie de plaque de guidage et une seconde partie de plaque de guidage qui guident verticalement un élément de guidage et qui présentent un mécanisme d'arrêt d'urgence coulissant. Un évidement ou une saillie est formé dans/sur l'extrémité de la première partie de plaque de guidage sur la direction de la largeur, et l'autre élément parmi un évidement et une saillie est formé dans/sur l'extrémité de la seconde partie de plaque de guidage sur la direction de la largeur. L'évidement et la saillie peuvent venir en prise l'un avec l'autre, et une longueur de traitement verticale est supérieure à un espace vertical par lequel la première partie de plaque de guidage et la seconde partie de plaque de guidage peuvent être espacées. L'évidement et la saillie sont disposés dans une position dans laquelle l'élément de guidage et le mécanisme d'arrêt d'urgence peuvent entrer en contact l'un avec l'autre.
