Abstract: Improved apparatus for bottom up shades to minimize gaps between the shade material and the lintel or between the shade material and the side of the window. In one apparatus a support rod is attached to a pull cord which is attached to the headrail which causes a rotation of the head rail and results in moving the top of the shade to the lintel. In another apparatus a centering cord moves the shade to the side and a side support rod symmetrically hangs the shade, thus, eliminating the gap on the side. A further improvement of a valance on the bottom acts to hide the mechanism and to act as a cradle for the shade material and headrail when the shade is in the down position.

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.
