Abstract
Abstract A drapery supporting linkage, adapted to be suspended from a stationary supporting rod and adapted to receive and hold the draperies in snap-on fashion, including a plurality of links pivotally interconnected adjacent their ends, in zigzag fashion, so that the links form the pleats in the draperies as they open and close, there being provided a pair of projecting ears on one end of each link supporting a male post therebetween, and an arcuate female hinge part or segment is formed integral with the body portion of the other end of each link. The male post end of one link is positioned next to the female hinge part of the adjacent link with the female hinge part receiving the male post to form a hinge connection between the adjacent links, there also being provided a pair of projecting ears adjacent the female hinge part or segment, but separately therefrom, to engage the projecting ears supporting the male post to limit the pivotal movement of the links with respect to one another. In one form of linkage, the projecting ears on the female segment have contact surfaces oriented in a way to contact the ears on the male post end of the adjacent link to guide the links into position for assembly and disassembly with reduced breakage of parts of the linkage. The linkage may have only one drapery supporting groove thereby reducing the size of the link and the amount of material used to make the link.
