Abstract

L'invention concerne un dispositif de porte pour un ascenseur disposé sur une section inférieure d'une porte battante unique. Un élément de prévention de déraillement de porte qui se place sous un cadre côté butée de porte contre lequel la porte vient en butée est disposé sur un sabot de porte ajusté dans une rainure de seuil d'un seuil. Une section de réception destinée à accueillir l'élément de prévention de déraillement de porte lorsque la porte a fermé un encadrement de porte est disposée au-dessous du cadre côté butée de porte. Du fait que l'élément de prévention de déraillement de porte vient dans la section de réception sous le cadre côté butée de porte lorsque la porte a fermé l'encadrement de porte, un déraillement de la porte là où le sabot de porte se sépare de la rainure de seuil est empêché, car même si une force externe est appliquée dans une direction perpendiculaire à la direction d'ouverture et de fermeture de la porte et que la porte fléchit, ce qui pourrait amener le sabot de porte à se déplacer vers le haut, l'élément de prévention de déraillement de porte vient en butée contre le cadre côté butée de porte, qui se trouve au-dessus de la section de réception, limitant ainsi le mouvement vers le haut du sabot de porte.
