CA 2559592

The invention relates to a curtain device mounted on a shaft (2) about which said curtain (1) can be wound to an open position and unwound into a closed position, a drive wheel (7) fixed coaxially to said shaft (2) and cooperating with said curtain (1) such as to displace the latter between said two positions. The device comprises an oblong flexible control body (11), cooperating with the drive wheel (7), said body (11) being embodied to permit the displacement of the curtain (1) between the open position and the closed position thereof, independently of the slack formed in the curtain (1) and to be able to be displaced along at least one of the lateral edges (4) of the curtain (1) and act upon the region (8) of the latter as opposed to that arranged on the shaft (2).

Dispositif à rideau monté sur un arbre (2) autour duquel ce rideau (1) peut être enroulé vers une position d'ouverture et dont il peut se dérouler vers une position de fermeture, une roue d'entraînement (7) étant fixée coaxialement sur cet arbre (2) et coopérant avec le rideau (1) d'une manière telle à pouvoir déplacer ce dernier entre ces deux positions. Ce dispositif comprend un organe de commande oblong flexible (11) qui coopère avec la roue d'entraînement (7), cet organe (11) étant agencé de manière à permettre, d'une part, de déplacer le rideau (1) entre sa position d'ouverture et sa position de fermeture 15 indépendamment du mou qui se serait formé dans le rideau (1) et, d'autre part, à pouvoir se déplacer le long d'au moins un des bords latéraux (4) du rideau (1) et agir sur la zone (8) de ce dernier opposé à celui monté sur l'arbre (2).
