Abstract

La présente invention vise à procurer un dispositif d'entrée/sortie de puits pour un ascenseur, lequel dispositif d'entrée/sortie de puits est installé en permanence sur la surface arrière d'un rail de guidage afin de permettre à un travailleur d'entrer et de sortir en sécurité et de façon pratique dans un puits. A cet effet, l'invention porte sur un dispositif d'entrée/sortie de puits pour un ascenseur, lequel dispositif d'entrée/sortie de puits (8) est installé à l'intérieur de la cage d'ascenseur (1) et est utilisé par un travailleur pour entrer et sortir dans le puits (7) dans la cage d'ascenseur à partir d'un accostage (2) et vers ce dernier, et a des plaques de marche (9) montées de façon écartée les unes des autres dans la direction verticale. Dans un plan de projection vertical à l'intérieur de la cage d'ascenseur, l'accostage et le rail de guidage (4a) pour guider un corps mobile verticalement sont respectivement disposés à l'intérieur de régions prédéterminées. Dans un plan de projection horizontal à l'intérieur de la cage d'ascenseur, les plaques de marche sont fixées à la surface arrière du rail de guidage ou au voisinage de cette dernière, de telle manière que les plaques de marche croisent la direction verticale du rail de guidage. La distance à partir d'une extrémité du rail de guidage, l'extrémité étant l'endroit où le rail de guidage et chacune des plaques de marche se croisent, jusqu'à une extrémité d'une partie de la plaque de marche, la partie s'étendant dans la direction s'éloignant à partir du rail de guidage, l'extrémité étant disposée sur le côté opposé au rail de guidage, est établie de façon à être supérieure ou égale à une largeur de pied.
