Abstract

La présente invention concerne un dispositif de fixation de cabine pour un ascenseur, où un élément mobile peut être déplacé par rapport à une cabine entre une position de mise en prise dans laquelle l'élément mobile peut se mettre en prise verticalement avec un élément fixe et une position de libération dans laquelle la mise en prise avec l'élément fixe est libérée. Un outil de libération est monté sur un premier élément parmi l'élément fixe et de l'élément mobile de façon à pouvoir être déplacé. Tandis que l'élément mobile est en prise verticale avec l'élément fixe, le déplacement de l'élément mobile vers la position de libération est bloqué par l'interférence entre l'outil de libération et l'autre élément qui est différent du premier élément. En déplaçant l'outil de libération par rapport au premier élément, l'outil de libération est libéré de la position interférant avec l'autre élément.
