Abstract
A drapery system that operates by rotating a rod having one, or a pair of left hand twist helical grooves, and one or a pair of right hand twist helical grooves, where the left hand twist and right hand twist helical grooves cross one another in equal spaced alignment across the length of the rotating rod. A plurality of idler rings and at least one driver ring are positioned around the drapery rod. The idler rings have a smooth interior surface whereas the driver rings include at least one tooth that engages a helical groove of the rotating rod. As the rotating rod is rotated, the driver ring is driven across the length of the rotating rod, thereby opening and closing the system. The system also includes a mounting bracket allows for extending the drapery past the inward edge of the inward most ring.
