Definitions

  • the present invention relates to a door device for an elevator.
  • automatic doors are smaller in size than elevator door devices, and the size of the door is limited in the direction perpendicular to the plane along the door surface.

It is generally done.
  • the door for the Elebe night has a large physique for the reason mentioned above, Furthermore, since the elevator door device is generally provided on a car, there are parts of the landing-side door device in a direction substantially orthogonal to a plane along the surface of the door. Strict dimensional restrictions are applied in the direction almost perpendicular to the plane along the door surface so that they do not come into contact with these parts during overnight driving. ). On the other hand, in the case of the elevator, the equipment is often placed at a higher position than the car ceiling, so the restrictions on the vertical dimensions are less strict than the automatic door, and it is 300 mm higher than the entrance height. In many cases, they have been loosened.

Therefore, the rotation of the door belt 1 is converted into the rotation of the door belt 4 between the driving pulley 2 and the driven pulley 3 on the horizontal plane.
  • the car side doors 12 and 13 connected by the ports 20 and 21 open and close.
  • door motor 1 was manufactured so as to be long and small in the axial direction of the rotation axis, and the rotation axis was arranged almost vertically.

If the diameter of the drive pulley 2 attached to the shaft is designed to be within the width of the rail frame 5, the diameter of the drive pulley 2 will be limited, and the drive pulley 2 will rotate with a small radius of curvature. The life of the door belt 4, which varies greatly, is reduced, and the weight of the car doors 12, 13 that can be driven is limited. Also, when a speed reducer is installed in the door device for the elevator, the reduction ratio cannot be increased if the speed reduction pulley is set within the width of the rail frame 5, and the speed reduction ratio cannot be increased.

Abstract

L'invention concerne un dispositif de porte pour ascenseur susceptible d'accroître la durée de vie de la courroie de porte et de protéger contre un accroissement de la masse des portes de cabines, sans pour autant augmenter la largeur d'un cadre de rail. Un moteur (1) de porte comporte un arbre rotatif disposé généralement de manière orthogonale à un plan suivant les surfaces des portes de cabines (12) et (13). La longueur de l'arbre rotatif est inférieure à une distance (W) séparant la partie extrémité côté plate-forme d'un seuil (19) et la partie extrémité côté cabine du cadre de rail (5). Enfin, le diamètre d'une poulie d'entraînement (2), installée autour de l'arbre rotatif du moteur (1) de porte, est indépendant de la distance (W).
