Claims
- 1. A collapsible covering having a front surface and a rear surface and comprising a plurality of cells on each of the front and rear surfaces, each cell including a pleated side on one of the front and rear surfaces and an opposing support side, with the pleated side having a fold defined by the material, the pleated side remaining pleated and the support side being substantially flat and coplanar with the support sides of the other cells when the covering is extended; and the material of each cell resiliently applying a force to fold the support side away from the pleated side when the covering is collapsed.
- 2. The collapsible covering of claim 1 wherein each cell has a triangular shape.
- 3. The collapsible covering of claim 1 wherein the fold in each cell protrudes away from the support side of the cell.
- 4. The collapsible covering of claim 1 wherein the fold in each cell protrudes towards the support side of the cell.
- 5. The collapsible covering of claim 1 wherein the cells are configured into a front and rear column of outer cells.
- 6. The collapsible covering of claim 5 wherein the outer cells have an identical shape and the material is folded to form a column of inner cells.
- 7. The collapsible covering of claim 6 wherein the inner cells have a shape different from the shape of the outer cells.
- 8. The collapsible covering of claim 6 wherein each of the inner cells has a triangular shape.
- 9. The collapsible covering of claim 1 further including a plurality of material sheets, each sheet defining the outer cells and having two ends with each end folded back onto the material to form the outer cells in a symmetric relation, wherein the plurality of sheets are attached together to define an inner cell.
- 10. The collapsible covering of claim 9 wherein the ends attach to opposite sides of the material.
- 11. The collapsible covering of claim 9 wherein the inner cell has a rectangular shape.
- 12. The collapsible covering of claim 1 wherein the covering is attached to a headrail and a foot rail.
- 13. A collapsible window covering comprising a length of material folded to form a plurality of planar layers, each layer connected by an adhesive line to an adjacent layer to define two outer cells, each cell having a pleated side with a fold defined by the material and an opposing support side having a substantially straight length, the length of material forming the support side being less than the material forming the pleated side, and, when the collapsible window covering is extended by bending each layer, the support side of the cells extending in a planar relationship to each other and each of the layers apply a force to collapse the covering.
- 14. The collapsible window covering of claim 13 wherein each outer cell has a triangular shape.
- 15. The collapsible window covering of claim 13 wherein the fold of each cell protrudes from the cell.
- 16. The collapsible window covering of claim 13 wherein the fold of each cell protrudes into the cell.
- 17. The collapsible window covering of claim 13 wherein the outer cells have an identical shape to each other.
- 18. The collapsible window covering of claim 17 wherein the material is folded to form an inner cell.
- 19. The collapsible window covering of claim 18 wherein the inner cell has a shape which is different from the outer cells.
- 20. The collapsible window covering of claim 19 wherein the inner cell has a triangular shape.
- 21. The collapsible window covering of claim 13 further including a plurality of sheets of material, each defining the outer cells and having two ends with each end folded back onto the material to form the outer cells in a symmetric relation to each other, wherein the plurality of sheets are attached together to define an inner cell.
- 22. The collapsible window covering of claim 21 wherein the ends attach to opposite sides of the material.
- 23. The collapsible window covering of claim 21 wherein the inner cell has a rectangular shape.
- 24. The collapsible window covering of claim 13 wherein the covering is attached to a head rail.
- 25. The collapsible window covering of claim 24 wherein the covering is attached to a foot rail.
- 26. A window covering comprising:
- a) headrail;
- b) a plurality of generally vertically disposed cells of material attached to the headrail, the cells collectively defining a support wall and a front surface and a rear surface, the support wall being substantially planar and the front and rear surfaces having pleats when the window covering is extended;
- c) the support wall applying a force to urge the covering into a collapsed condition; and
- d) a foot rail having sufficient weight to extend the window covering.
- 27. The window covering of claim 26 wherein the pleats are uniformly disposed on the front and rear surfaces.
