Abstract

La présente invention empêche une poignée d'actionnement utilisée pour le déverrouillage de tomber dans une cage d'ascenseur lors du déverrouillage et de l'ouverture manuelle d'une porte palière. Un mécanisme de libération manuelle est disposé sur le côté de la porte palière faisant face à une porte de cabine, et déverrouille un mécanisme de verrouillage côté palier. La porte palière présente un trou de raccordement de poignée dans lequel la poignée d'actionnement est insérée depuis le côté palier afin de raccorder le mécanisme de libération manuelle et la poignée d'actionnement. En outre, lorsque le palier est manuellement ouvert avec la poignée d'actionnement insérée dans le trou de raccordement de poignée et que la poignée d'actionnement interfère avec une entrée de porte qui est prévue dans le palier d'un bâtiment, l'ouverture de la porte palière est d'une taille telle qu'une personne ne peut pas passer.
