Abstract
A spring clutch mechanism for the operation of roller shades and other rollable items. This clutch mechanism is designed to release for raising the shade 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 accomplished by overriding the clutch, causing it to slip. The clutch can be adapted easily to accommodate know shade weights. The inventive design provides superior operating characteristics and, because the clutch can be built with as few as two parts, much lower cost.
