Abstract
A cellular pleated shade material is provided for cellular pleated shades. Each pleat thereof is formed from a single strip of shade material which is folded longitudinally in half, and the edges thereof are glued together to form a fin. The side of one cell is affixed to the side of the next adjacent cell adjacent the centerline of the sides. The ratio of cell height to cell width may be varied, without affecting the overall aesthetic presentation of the shade, by varying the size of the fin.
Claims34
A cellular pleated shade member having a plurality of cells, at least one of the cells comprising:
- a strip of shade material folded lengthwise to form an upper cell wall and a lower cell wall extending from a fold, each upper and lower cell wall having a free edge and a folded edge merging with the adjacent wall of the strip at said fold;
- said upper cell wall and lower cell wall of said strip connected adjacent their respective free edges and forming a fin at said connection;
- wherein said upper cell wall is attached to a lower cell wall of a first adjacent cell at an upper interconnection zone, said upper interconnection zone being located on said upper cell wall between said fin and said fold;
- and
- wherein said lower cell wall is attached to an upper cell wall of a second adjacent cell at a lower interconnection zone, said lower interconnection zone being located on said lower cell wall between said fin and said fold.
