Abstract

Dispositif de porte d'ascenseur comprenant une porte qui ouvre et ferme une passerelle, un rail positionné au-dessus de la passerelle, et un seuil qui est positionné sous la passerelle, une rainure de guidage étant formée par le seuil. La porte comporte un guide supérieur, un butoir supérieur, un guide inférieur et un butoir inférieur. Le guide supérieur comporte une partie de rainure, l'extrémité supérieure du rail étant introduite dans la partie de rainure. Le butoir supérieur fait face à la surface inférieure du rail. Le guide inférieur est introduit dans la rainure de guidage dans le seuil. La butée inférieure fait face à la surface supérieure du seuil et s'étend vers la surface supérieure du seuil et dans une direction vers le côté inverse de la porte. Lorsque la porte est pressée depuis le côté avers et s'incurve vers le côté inverse et que le butoir inférieur est pressé contre la surface supérieure du seuil, la porte est pressée vers le haut et le butoir supérieur est pressé contre la surface inférieure du rail en raison d'une force antagoniste produite au niveau du point de contact entre le butoir inférieur et la surface supérieure du seuil, et la porte est tendue entre la surface supérieure du seuil et la surface inférieure du rail, réduisant au minimum la courbure de la porte.
