A spring clutch mechanism (5) for the operation of roller shades (1) and other rollable items. This clutch mech- anism (5) is designed to release for rais- ing the shade (1) so as to minimize effort. Whereas prior art clutch mechanisms for roller shades are intended not to slip, or to slip only to save themselves, in this case, lowering of the shade is accom- plished by overriding the clutch, caus- ing it to slip. The clutch (5) can be adapted easily to accommodate known shade (1) weights. The inventive de- sign provides superior operating charac- teristics and, because the clutch (5) can be built with as few as two parts, much lower cost.

L'invention concerne un mécanisme d'accouplement à ressort (5) permettant d'actionner des stores à enrouleur (1) et autres articles pouvant être enroulés. Ce mécanisme d'accouplement (5) est conçu pour se désengager afin de permettre le relèvement du store (1) avec un effort minimum. Alors que les mécanismes d'accouplement de stores à enrouleur de la technique antérieure ne sont pas conçus pour glisser, ou glissent uniquement pour éviter d'être endommagés, l'abaissement du store, dans le cas de l'invention, s'effectue par passage en roue libre de l'accouplement, ce qui provoque son glissement. L'accouplement (5) peut être facilement adapté pour supporter les poids de stores (1) connus. La conception de l'invention permet d'obtenir des caractéristiques de fonctionnement supérieures pour un coût nettement inférieur car l'accouplement (5) est seulement constitué de deux pièces.
