Claims
- 1. A radially expansible shade comprising:
- a multi-cellular or pleated fabric, a first margin of said fabric comprising a length of cell or pleat which is radially and movably spacable from a second similar margin of said fabric by pivotation about a nominal radial center; and
- a strip-like flexible hinge having a continuous bottom surface and a top surface that is adhesively secured to an entire lateral edge of said fabric that is proximate said nominal radial center whereby when said shade is in a compressed state, said hinge is substantially straight and when said shade is in a fully open fan-shaped condition in which said first and second margins are approximately 180 degrees apart and said fabric is symetrically deployed about said hinge, said hinge assumes a "U" shape.
- 2. The shade of claim 1 wherein said hinge further comprises a plurality of digit members that extend upwardly from the top surface of said hinge and are each attached to said fabric.
- 3. The shade of claim 2 wherein one of said plurality of digit members is located at a first end of said hinge and another of said digit members is located at a second end of said hinge.
- 4. The shade of claim 3 wherein the digit member located at the first end of said hinge attaches to said fabric proximate its first margin and the digit member located at the second end of said hinge attaches to said fabric proximate its second margin.
- 5. A method for hinging a radially expansible fan shade comprised of multiple pleats or cells arrayed to dispose a lateral edge of pleat or cell ends arcuately between two external pleat or cell margins, said hinging comprising the steps of: collapsing the shade so as to bundle the pleats or cells tightly along said lateral edge; and
- securing the bundled edge to a flat top surface of a unitary, essentially planar hinge comprised of a flexible strip of suitable material having a continuous bottom surface that allows the hinge to be bent into a "U" shape, said securing being accomplished so that the spacing between said pleat or cell ends is uniform over said strip and wherein the location of the pleat or cell ends defines their points of attachment on the top surface of the hinge.
- 6. The method of claim 5 wherein said securing step comprises adhesively fixing said lateral edge to said top surface of said hinge.
