Definitions

  • the object of the invention is therefore to propose a wheel for driving a flexible handrail of an escalator or a moving walkway, with which the disadvantages of the prior art are avoided.
  • the main advantages of the new wheel are the prevention of the slip-stick effect between the wheel and the handrail and the prevention of bead formation in the contact area between the wheel and the handrail.
  • the beading is essentially dependent on the respective material stiffness together with the material thickness, as depending on the contact area between the tire casing and handrail both in the direction of movement and transverse to form beads that have vibrations and thus noise and wear result.
  • the outer layer usually has a structure on its outer peripheral surface.
  • a structure with circumferentially extending grooves allows the outflow of water that can pass through the handrail in the contact area of handrail and outer layer.
  • Other structures can serve to improve the above-mentioned frictional connection.
  • Fig. 2 shows a wheel according to the invention, which has an inner layer 20, a middle layer 30 and an outer layer 40.
  • an outer layer 40 Adjacent to an outer peripheral surface 32 of the middle easily deformable layer 30, an outer layer 40 is provided.
  • the outer layer 40 is bonded to the middle layer 30 such that rotation of the middle layer 30 causes synchronous rotation of the outer layer 40.
  • the connection of the middle layer 30 with the outer layer 40 is such that the mentioned movement coupling comes about through a frictional connection or gluing or fusion.

Claims (10)

  1. Poulie (10) pour entraîner une main courante flexible (11) d'un escalier roulant ou d'un trottoir roulant, qui est apte à tourner sur un axe de rotation (A) et qui présente une couche à bonne déformabilité élastique (30),
    étant précisé que la couche à bonne déformabilité élastique (30) est formée par un corps de forme stable, en soi, en l'absence de contrainte,
    qu'il est prévu, près d'une surface circonférentielle intérieure (31) de la couche à bonne déformabilité élastique (30), une couche intérieure (20) qui est plus rigide que ladite couche à bonne déformabilité élastique (30),
    qu'il est prévu, près d'une surface circonférentielle extérieure (32) de la couche à bonne déformabilité élastique (30), une couche extérieure (40) qui est destinée à s'appliquer contre la main courante (11) en adhérant à celle-ci, et
    que les couches voisines (20, 30 et 30, 40) sont accouplées entre elles en étant fixes en rotation,
    caractérisée en ce que le corps qui forme la couche centrale (30) présente des creux (34).
  2. Poulie (10) selon la revendication 1, caractérisée en ce que la couche intérieure (20) est formée sur un corps de jante de la poulie (10) ou fait partie d'un corps de jante.
  3. Poulie (10) selon l'une des revendications précédentes, caractérisée en ce que le corps qui forme la couche centrale (30)
    - a globalement la forme d'un cylindre creux et
    - présente des creux (34) qui s'étendent de préférence dans le sens circonférentiel.
  4. Poulie (10) selon la revendication 3, caractérisée en ce que les creux (34) sont constitués par des ouvertures ou des évidements qui communiquent avec l'extérieur de la couche centrale (30).
  5. Poulie (10) selon la revendication 3, caractérisée en ce que les creux (34)
    - sont inclus à l'intérieur de la couche centrale (30)
    - et contiennent un matériau compressible, de préférence fluide.
  6. Poulie (10) selon l'une des revendications précédentes, caractérisée en ce que la couche extérieure (40) présente un renforcement (50) qui est formé de préférence par des éléments rigides oblongs en forme de fils ou de tresses.
  7. Poulie (10) selon la revendication 6, caractérisée en ce que le renforcement (50) est contenu dans la couche extérieure (40).
  8. Poulie (10) selon la revendication 6, caractérisée en ce que le renforcement (50) est contenu dans une couche partielle (41) de la couche extérieure (40).
  9. Poulie (10) selon l'une des revendications précédentes, caractérisée en ce que la couche extérieure (40) présente, sur une surface extérieure destinée à être appliquée contre la main courante (11), des nervures (42) qui s'étendent de préférence dans le sens circonférentiel.
  10. Poulie (10) selon la revendication 9, caractérisée en ce que la surface destinée à être appliquée contre la main courante (11) est une surface circonférentielle extérieure de la couche extérieure (40) et/ou de la couche partielle (41).
