Abstract: The object of the present invention is to provide window coverings for nonrectangular windows and openings. The present invention utilizes a sliding headrail which allows a shade to be fitted exactly to a myriad of nonrectangular window shapes and to be opened or closed without placing undue stress upon the shade material or causing unsightly bunching of the shade material. A single headrail may also be used in appropriate circumstances. The sliding headrail keeps shade material neat and flat within the window frame, and if pleated or honeycombed, maintains the pleats in their natural horizontal arrangement. The window shade is not limited to the use of any particular shade materials, and can use virtually any window covering material depending on the appropriateness of the application. Shade material is attached to the sliding headrail segments at various points via shade leveling rods and support rods.
