Abstract

L'invention concerne un dispositif ascenseur conçu de sorte qu'une paire de mains courantes latérales comporte des éléments main courante fixes et des éléments main courante mobiles, les éléments main courante mobiles étant disposés aux extrémités supérieures des éléments main courante fixes et pouvant être déplacés entre une position relevée selon laquelle les éléments main courante mobiles sont relevés à partir des extrémités supérieures des éléments main courante fixes, et une position repliée selon laquelle les éléments main courante mobiles sont repliés par rapport aux extrémités supérieures des éléments main courante fixes. En position repliée, les éléments main courante mobiles sont situés au niveau de la partie intermédiaire d'une ouverture d'accès plafond dans la direction de la hauteur tout en se faisant face dans la direction de la largeur de l'ouverture d'accès plafond. L'un des éléments main courante mobiles est équipé d'un corps à détecter, et l'autre est équipé d'un commutateur de détection. Lorsque chacun des éléments main courante mobiles est en position repliée, le commutateur de détection peut détecter le corps à détecter.
