Abstract
A balloon-type shade utilizes bands of low-friction material, attached to a flap on the shade, for guiding the drawstrings at their points of directional change from vertical to horizontal. This permits the shade to be prestrung, independently of any rigid mounting rod, and thereby enables shipment in a flat, folded condition.
Claims12
A prestrung balloon shade, comprising:
- a main panel of supple material;
- a strip of supple material extending across the top of said panel on one side thereof;
- means for attaching said strip to said main panel along at least one laterally extending line, and defining a rod-receiving sleeve portion thereabove and a marginal portion of said strip therebelow;
- a plurality of relatively rigid loops affixed, by relatively non-protruding means, on and depending from said marginal portion of said strip at laterally spaced locations, each of said loops being fabricated from a low friction material, and defining laterally extending channels therethrough, said channels being aligned generally on an axis parallel to the plane of said panel and lying closely adjacent thereto;
- a multiplicity of guide elements arranged in rows and columns on said one side of said main panel, each of said columns being aligned under an associated one of said loops;
- and
- a corresponding plurality of drawstrings, each attached to said panel adjacent the lower edge thereof and being threaded through said guide elements of one of said columns, and through said associated loop to extend therefrom only in the direction of one side edge of said panel, said drawstrings all being threaded through at least the one of said loops positioned most closely adjacent said one side edge, the suppleness of said material of said main panel and said attached strip allowing intentional gathering thereacross to permit variation in the expanse of said shade when mounted upon a rod received through said sleeve portion thereof.
4 more elements
A balloon shade assembly including:
- (a) a balloon shade comprised of a main panel of supple material, a strip of supple material extending across the top of said main panel on one side thereof, means for attaching said strip to said main panel along at least one laterally extending line, and defining a rod-receiving sleeve portion thereabove and a free marginal portion of said strip therebelow, a plurality of relatively rigid loops affixed, by relatively non-protruding means, on and depending from said marginal portion of said strip at laterally spaced locations, each of said loops being fabricated from a low friction material and defining a laterally extending channel therethrough, said channels being aligned generally on an axis parallel to the plane of said panel and lying closely adjacent thereto, a multiplicity of guide elements arranged in rows and columns on said one side of said main panel, each of said columns being aligned under an associated one of said loops, and a corresponding plurality of drawstrings, each attached to said panel adjacent the lower edge thereof and being threaded through said guide elements of one of said columns, and through said associated loop to extend therefrom only in the direction of one side edge of said panel, said drawstrings all being threaded through at least the one of said loops most closely adjacent said one edge;
- and
- (b) a mounting rod received within said sleeve portion of said shade, said shade and rod being devoid of other means attaching them to one another, and the suppleness of said material of said main panel and said attached strip allowing intentional gathering thereacross, said shade thereby being of readily adjustable width on said rod.
