Abstract

The present invention is an improved multi-cellular shade which is adapted to be mounted within a window and in particular a non-vertical window. The shade has a cut away portion on each of its end. This cut away portion is defined by a stepped section that terminates in an angled section as viewed from the rear side toward the front side of the shade. The stepped section is further defined by two substantially perpendicular walls, one wall being generally perpendicular to the faces of the shade and the second wall being generally parallel to the faces. The second or parallel wall terminates in the angled portion, and the angled portion is at a generally obtuse angle to the second wall. Preferably, the cutaway end of the shade is configured to be recieved with in a C-shaped channel. The channel has a lower leg for supporting the shade and an upper leg having a track for receipt of a drive mechanism to expand and retract the shade, and a flange which extends over a portion of the shade to prevent bowing of the shade. By such disclsoed apparatus, interferences that cause binding are avoided while structural strength of the cellular material is retained.
