1. A cellular pleated shade member having a plurality of interconnected 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;
said upper cell wall and lower cell wall of said strip interconnected adjacent their respective free edges; and
said upper cell wall and said lower cell wall each having at least one attachment zone on each side of a longitudinal center line of each said cell wall for connecting said cell to an adjacent cell.

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.

10. A cellular shade for covering a window, said shade comprising:
-
a plurality of longitudinally extending, substantially parallel interconnected fabric cells, wherein substantially all cells within said plurality of cells have for each cell; a front side and a rear side; a crease forming a tip on said front side; an upper cell wall extending from said crease and having a rear edge, said upper cell wall having a longitudinal center line equidistant along said upper cell wall from said crease and from said rear edge of said upper cell wall; a lower cell wall extending from said crease and having a rear edge, said lower cell wall and said upper cell wall being substantially equal in length; and a fin on said rear side, wherein said fin is formed by joining a portion of said upper cell wall adjacent said rear edge of said upper cell wall with a portion of said lower cell wall adjacent said rear edge of said lower cell wall; and material located on at least one of said upper cell wall and said lower cell wall for attaching each cell of said plurality of cells to an adjacent cell of said plurality of cells. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A cellular shade for covering a window, said shade comprising:
-
a plurality of longitudinally extending interconnected fabric cells, wherein each cell within said plurality of cells has; a front side and a rear side; a crease forming a tip on said front side; an upper cell wall extending from said tip and having a rear edge, said upper cell wall having an upper surface and an interior surface and having a longitudinal center line equidistant along said upper cell wall from said tip and from said rear edge of said upper cell wall; a lower cell wall extending from said tip and having a rear edge, said lower cell wall having a lower surface and an interior surface, said lower cell wall and said upper cell wall being substantially equal in length; and a fin on said rear side, wherein said fin is formed by joining a first portion of said interior surface of said upper cell wall adjacent said rear edge of said upper cell wall with a first portion of said interior surface of said lower cell wall adjacent said rear edge of said lower cell wall; an adhesive on substantially all cells of said plurality of cells, said adhesive for connecting each cell of said substantially all cells to an adjacent cell of said plurality of cells; an upper rail assembly, said upper rail assembly attached to an uppermost cell of said plurality of cells; a lower rail assembly, said lower rail assembly attached to a lowermost cell of said plurality of cells; and a pullcord, said pullcord for raising and lowering one of said upper and lower rail assembly in relation to the other of said upper and lower rail assembly. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A cellular shade for covering a window, said shade comprising:
-
a plurality of longitudinally extending interconnected fabric cells, wherein substantially all cells within said plurality of cells have for each cell; a front side and a rear side; a crease forming a tip on said front side; an upper cell wall extending from said tip and having a rear edge, said upper cell wall having an upper surface and an interior surface and having a longitudinal center line equidistant along said upper cell wall from said tip and from said rear edge of said upper cell wall; a lower cell wall extending from said tip and having a rear edge, said lower cell wall having a lower surface and an interior surface; and a fin on said rear side, wherein said fin is formed by joining a first portion of said interior surface of said upper cell wall adjacent said rear edge of said upper cell wall with a first portion of said interior surface of said lower cell wall adjacent said rear edge of said lower cell wall; an adhesive on substantially all cells of said plurality of cells, said adhesive for connecting each cell of said substantially all cells to an adjacent cell of said plurality of cells, wherein said adhesive includes a first glue bead on said upper surface of said upper cell wall and a second glue bead on said upper surface of said upper cell wall, said first and said second glue beads being on opposite sides of said longitudinal center line of said upper cell wall, said first and said second glue beads extending longitudinally along said upper surface of said upper cell wall; an upper rail assembly, said upper rail assembly attached to an uppermost cell of said plurality of cells; a lower rail assembly, said lower rail assembly attached to a lowermost cell of said plurality of cells; and a pullcord, said pullcord for raising and lowering said one of said upper and lower rail assembly in relation to the other of said upper and lower rail assembly; wherein when said cellular shade is extended, a second portion of said interior surface of said upper cell wall and a second portion of said interior surface of said lower cell wall define a six-sided polygon, said six-sided polygon having an upper rear side, an upper middle side, an upper front side, a lower front side, a lower middle side, and a lower rear side; the length of said upper middle side and said lower middle side are of approximately equal lengths, the length of said upper middle side being less than the length of either of said upper rear side and said upper front side, and the length of said lower middle side being less than the length of either of said lower rear side and said lower front side; and said fin, said upper middle side and said lower middle side are in substantially parallel arrangement.
