Abstract

A curtain rail consists of a number of interconnected lengths of extruded aluminium support rail of inverted channel section with inwardly projecting ribs at the mouth of the channel section. In the installed curtain rail, the ribs are embraced by one-piece or continuous plastics glide tracks engaged by necked nylon runners. The cross-sectional configurations of the ribs and the tracks are mutually complementary so that the tracks can be press-fitted manually and are self-retaining. The preferred track is a P.V.C. extrusion of C-shaped section. The arrangement provides, conveniently and economically, the advantage of easy handling and transporting associated with multi-piece support rail, coupled with the advantage of quiet click-free operation.
