Abstract

L’encadrement de porte d'une cabine d'ascenseur est ouverte et fermée par une porte de cabine. A l'extrémité du côté de fermeture de porte de la porte de cabine, on a mis en œuvre un organe de manœuvre en mesure d'être déplacé entre une position en saillie selon laquelle l'organe de manœuvre est en saillie en provenance de l'extrémité inférieure de la porte de cabine et une position rétractée située au-dessus de la position en saillie. L'organe de manœuvre est déplacé jusqu’à la position en saillie quand l’entrée de porte est entièrement fermée par la porte de cabine et il est déplacé jusqu’à la position rétractée quand la porte de cabine est déplacée dans la direction de fermeture de porte. Un seuil de porte muni d'un trou de seuil est mis en œuvre au niveau de la partie inférieure de l’encadrement de porte. L'organe de manœuvre est inséré dans le trou de seuil de porte quand l'organe est déplacé jusqu’à la position en saille par le mouvement de la porte de cabine. De plus, l'organe de manœuvre est retiré du trou de seuil de porte quand l'organe est déplacé jusqu’à la position en saillie. Tout déplacement de l'organe de manœuvre jusqu’à la position en saillie est détecté par un commutateur de détection. Par ailleurs, le dispositif de commande de porte commande le mouvement de la porte de cabine en fonction des informations provenant du commutateur de détection.
