Abstract
Abstract A window shade having a transversely symmetrical design. By a ''''transversely symmetrical design'''' is meant a design that extends across the shade either in the form of a scalloped or otherwise configurated lower edge, or in the form of an overall print so that the two edgewise areas of the design are the same. The disclosure is concerned primarily with a window shade roller of the type set forth that is adapted to be shortened quickly and easily by first cutting and removing equal widths of shade material from both ends of the roller, in order to preserve the symmetry of design, and second, telescoping the roller to bring the respective ends of the roller into proper relationship with the newly cut edges of the shade.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
234 words
In a window shade and roller combination wherein the shade is of readily cuttable material and is characterized by having a transversely symmetrical design thereon, the improvement to permit shortening of the overall length of the combination while preserving the symmetry of the design which comprises; a first roller section, said first roller section being tubular; a second roller section, said second roller section having one end thereof telescopingly seated within said first section and a substantial portion thereof projecting axially from said first section; a tube of readily cuttable material coextensive with and surrounding both of said roller sections; adhesive means securing the upper end of said window shade to said tube; and friction means interposed between said tube and said first roller section, said friction means characterized in permitting longitudinal telescoping movement but resisting relative rotative movement between said tube and said first roller section, whereby the cutting of said shade and said tube in a plane normal to the longitudinal axis of said roller at one end of said combination frees and end part of said shade and said tube to permit removal thereof and the similar cutting of an equal end part of said shade and said tube at the opposite end of said combination permits removal thereof, whereupon the first roller section may be telescoped into said tube and said second section may be telescoped into said first section.
Claim 2
Dependent Claim
234 words
In a window shade and roller combination wherein the shade is of readily cuttable material and is characterized by having a transversely symmetrical design thereon, the improvement to permit shortening of the overall length of the combination while preserving the symmetry of the design which comprises; a first roller section, said first roller section being tubular; a second roller section, said second roller section having one end thereof telescopingly seated within said first section and a substantial portion thereof projecting axially from said first section; a tube of readily cuttable material coextensive with and surrounding both of said roller sections; adhesive means securing the upper end of said window shade to said tube; and friction means interposed between said tube and said first roller section, said friction means characterized in permitting longitudinal telescoping movement but resisting relative rotative movement between said tube and said first roller section, whereby the cutting of said shade and said tube in a plane normal to the longitudinal axis of said roller at one end of said combination frees and end part of said shade and said tube to permit removal thereof and the similar cutting of an equal end part of said shade and said tube at the opposite end of said combination permits removal thereof, whereupon the first roller section may be telescoped into said tube and said second section may be telescoped into said first section.
Claim 3
Dependent Claim
29 words
The combination as set forth in claim 1 in which said friction means comprises at least one rubber band seated on and extending circumferentially around said first roller section.
Claim 4
Dependent Claim
28 words
The combination as set forth in claim 1 in which said tube is serrated longitudinally in the outer endwise portion thereof at said one end of said combination.
Claim 5
Dependent Claim
289 words
In a window shade and roller combination wherein the shade is of easily cuttable material and characterized by having a transversely symmetrical design, the improvement to permit shortening of the overall length of the combination while preserving the symmetry of the design which comprises; a first roller section, said first roller section being tubular; a second roller section, said second section having one end thereof telescopingly seated within said first section and a substantial portion thereof projecting from said first section; a first tube of readily cuttable material having an outside diameter approximately equal to the outside diameter of said first section and an inside diameter of a size to permit free-sliding movement between the inside of said first tube and said first section; said first tube surrounding said projecting portion of said second section and having one end thereof abutting the end of said first section; a second tube of readily cuttable material coextensive with and surrounding said roller sections, including said first tube; adhesive means securing the upper end of said window shade to said second tube; friction means interposed between said second tube and said first roller section, said friction means characterized in permitting relative longitudinal telescoping movement but resisting relative rotative movement between said second tube and said first roller section; and whereby upon the cutting and removal of an end part of said shade and of said second tube at the one end of said roller the roller may be telescoped into said second tube and whereby the cutting of an equal end part of sAid shade and said second tube and said first tube at the opposite end of said roller, the second roller section may be telescoped into said first roller section.
Claim 6
Dependent Claim
289 words
In a window shade and roller combination wherein the shade is of easily cuttable material and characterized by having a transversely symmetrical design, the improvement to permit shortening of the overall length of the combination while preserving the symmetry of the design which comprises; a first roller section, said first roller section being tubular; a second roller section, said second section having one end thereof telescopingly seated within said first section and a substantial portion thereof projecting from said first section; a first tube of readily cuttable material having an outside diameter approximately equal to the outside diameter of said first section and an inside diameter of a size to permit free-sliding movement between the inside of said first tube and said first section; said first tube surrounding said projecting portion of said second section and having one end thereof abutting the end of said first section; a second tube of readily cuttable material coextensive with and surrounding said roller sections, including said first tube; adhesive means securing the upper end of said window shade to said second tube; friction means interposed between said second tube and said first roller section, said friction means characterized in permitting relative longitudinal telescoping movement but resisting relative rotative movement between said second tube and said first roller section; and whereby upon the cutting and removal of an end part of said shade and of said second tube at the one end of said roller the roller may be telescoped into said second tube and whereby the cutting of an equal end part of sAid shade and said second tube and said first tube at the opposite end of said roller, the second roller section may be telescoped into said first roller section.
Claim 7
Dependent Claim
29 words
The combination as set forth in claim 4 in which said friction means comprises at least one rubber band seated on and extending circumferentially around said first roller section.
Claim 8
Dependent Claim
29 words
The combination as set forth in claim 4 in which said second tube is serrated longitudinally in the outer endwise portion thereof at said one end of said roller.
