  • These cords are wound up on the winding cylinder when the curtain is to be lifted and unwound from the winding cylinder when the curtain is to be lowered.
  • the cords are wound up on a winding cylinder which is displaced in axial direc ⁇ tion, whereby the windings are arranged uniformly in juxtaposition. If the winding cylin ⁇ der was not displaced in axial direction during the winding action, the windings would be arranged more or less randomly on top of each other, which may cause an uneven winding up.
  • Winding devices in which the winding cylinder is displaced in axial direction during the winding action, are known from the patent literature.

  • the slide may be fastened to a rail by means of releasable fastening means.
  • releasable fastening means As a result improved flexibility is obtained as the slide or slides may be displaced and secured in the desired position on the rail.
  • the slide includes a guide means for the cord, whereby a controlled winding of the cord is ensured.
  • the winding cylinder extends past one end of the stationary cylinder and includes an end cover being rotationally connected with the drive shaft.
  • the drive shaft has a polygonal cross section and the end cover has an axial hole with a corresponding polygonal cross section, whereby the driv ⁇ ing connection between the drive shaft and the winding cylinder is obtained in a par ⁇ ticularly simple manner.
  • the winding device includes at least two winding units.
  • the winding device includes at least two winding units with opposing threads such that the winding cylinders are moved in opposite axial directions during winding.
  • the end covers of the two wind ⁇ ing units face outwards towards the outer edge of the curtain or Venetian blind.
  • the cords may thus be positioned relatively close to the edge in both sides. This is particu- larly advantageous in so-called roman blinds, as it further ensures that the curtain is folded correctly when lifted.

  • the winding cylinder 1 has an outer diameter of about 20 mm. If the cord 9 has a diameter of about 1 mm, a uniform winding, in which the wind ⁇ ings are arranged side by side, of a cord of about 2.5 m will cover nearly 4 cm of the length of the winding cylinder 1. When the end covers 6 face the edge of the curtain, the outermost cords for a curtain of a height of 2.5 m may thus be arranged about 4 cm from the edges of the curtain.

Abstract

L'invention porte sur un dispositif de commande de rideaux et de persiennes et analogues permettant d'enrouler ou de dérouler un cordon pour les lever ou les baisser. Ledit dispositif comporte: un ou plusieurs unités d'enroulement (13) comprenant chacune: un cylindre enrouleur (1) à filetage intérieur autour duquel peut s'enrouler ou se dérouler le cordon (9) de manoeuvre; un cylindre fixe (2) à filetage extérieur (3) s'engageant dans le filetage interne (4) du cylindre enrouleur (1); un arbre d'entraînement à commande manuelle ou motorisée dont la rotation entraîne la rotation et le déplacement axial du cylindre enrouleur (1) ainsi que la montée ou la descente du store. Le cylindre fixe (2) comporte un alésage traversant (14) abritant l'arbre de commande (8).
