Abstract
A drapery system having a drive element extending the length that is connected to a structure by a pair of brackets. The drive element has a cylindrical shape with an exterior surface. The exterior surface of the drive element has a guide structure, which in one arrangement is a plurality of helical grooves. A plurality of rings are positioned around the drive element that are used to connect shade material to the drive element. The rings include a partial driver ring, a full driver ring and idler rings. In a center closing arrangement, partial driver rings are positioned as the inward most rings followed by full driver ring which is followed by a plurality of idler rings. The partial driver ring and the idler rings have a stabilizer that fits around the exterior surface of the drive element thereby providing smoother and quieter travel along the drive element.
