Abstract
Abstract This invention is directed to a window shade whose width can be decreased, without cutting instruments, to conform to the size of the window opening into which the shade is to be mounted. The window shade includes a roller and a shade secured to the roller having at one or both edges a plurality of spaced strip lines, preferably invisible, extending from end-to-end parallel to the shade edges. The strip lines permit hand-stripping of discrete widths of the shade while the shade is rolled on the roller. The roller includes substantially coincident with the strip lines of the shade a plurality of longitudinally spaced, circumferentially extending strip lines permitting removal of a corresponding discrete length of the roller. In accordance with the invention disclosed, the shade includes a plurality of integral tabs at the hem end of the shade whose edges generally coincide with the strip lines to facilitate the stripping of discrete widths of the shade.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
246 words
A window shade comprising, in combination, a roller having a telescoping member receivable in one end, a shade secured along one end of said roller and extending between the ends of said roller, and having an opposite free end, said shade having a hem opposite said end secured to said roller formed of overlapping shade portions joined along a hem line spaced from the free end of said shade, and having at least one edge thereof a plurality of spaced hand-strip lines extending from end-to-end substantially parallel to said edge such that discrete widths of said shade may be hand-stripped along said lines from said free end of said shade to provide a smooth, straight edge after stripping, said roller including at least at its end receiving the telescoping member a plurality of longitudinally spaced, circumferentially extending strip lines substantially coincident with said lines of said shade adapted to permit removal of discrete lengths of said roller corresponding to said discrete widths of said shade hand-stripped therefrom, and a plurality of tabs associated with said hem, each said tab extending between said hem line and said free end of said shade, the edges of said tabs being substantially coincident with said hand-strip lines, said tabs being adapted to be grasped and pulled to separate said overlapping shade portions and initiate stripping along said lines from said free end of said shade toward said end secured to said roller while said shade is rolled on said roller.
Claim 2
Dependent Claim
246 words
A window shade comprising, in combination, a roller having a telescoping member receivable in one end, a shade secured along one end of said roller and extending between the ends of said roller, and having an opposite free end, said shade having a hem opposite said end secured to said roller formed of overlapping shade portions joined along a hem line spaced from the free end of said shade, and having at least one edge thereof a plurality of spaced hand-strip lines extending from end-to-end substantially parallel to said edge such that discrete widths of said shade may be hand-stripped along said lines from said free end of said shade to provide a smooth, straight edge after stripping, said roller including at least at its end receiving the telescoping member a plurality of longitudinally spaced, circumferentially extending strip lines substantially coincident with said lines of said shade adapted to permit removal of discrete lengths of said roller corresponding to said discrete widths of said shade hand-stripped therefrom, and a plurality of tabs associated with said hem, each said tab extending between said hem line and said free end of said shade, the edges of said tabs being substantially coincident with said hand-strip lines, said tabs being adapted to be grasped and pulled to separate said overlapping shade portions and initiate stripping along said lines from said free end of said shade toward said end secured to said roller while said shade is rolled on said roller.
