Abstract

L'invention porte sur un dispositif de porte dans lequel une première porte de cabine ouvre et ferme une embrasure de porte de cabine. Une première porte palière ouvre et ferme une porte palière en se déplaçant conjointement avec la première porte de cabine tout en faisant face à la première porte de cabine. Un capteur détecte un objet qui a pénétré dans une première région de détection. Un élément de guidage est disposé entre la première porte de cabine et la première porte palière. En outre, l'élément de guidage est disposé dans une plage dans le sens de la hauteur de la première porte de cabine et de la première porte palière. De plus, l'élément de guidage guide un objet allongé s'étendant à travers la porte de cabine et la porte palière jusqu'à la première région de détection en se déplaçant, conjointement avec la première porte de cabine et la première porte palière, dans la direction de fermeture de l'encadrement de porte de cabine et de l'encadrement de porte palière.
