Definitions

  • 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,
  • the present invention is addressed primarily to the problem posed by a window shade having a transversely symmetrical design wherein the removal of one edgewise area only of the shade material would in most instances destroy the symmetry of design. More specifically, the invention is directed to a shade construction that may be reduced in size quickly and easily by removing equal widths of shade material from both edgewise areas of the shade, thereby preserving symmetry of design, with provision being made to telescope both sections of the roller back into the shade.
  • shade construction of this invention is best suited for operations wherein shade material is cut and removed from both ends of a roller, as will be seen, it has equal utility wherein it is desired to remove shade material from one end of the roller only, and at either end with equal facility.
  • FIG. 1 is an exploded view illustrating the components of a preferred shade construction incorporating the principals of the present invention
  • FIG. 2 is a longitudinal cross-sectional view of an assembled shade
  • FIG. 3 is a view similar to FIG. 2 showing shade material removed from one end of the shade
  • FIG. 4 is a view similar to FIG. 2 showing shade material removed from the opposite end of the shade.
  • FIG. Si is a view similar to FIG. 2 showing a modified form of the invention.
  • window shade includes the entire assembly of shade roller, the components associated with it, and the sheet of window shade material that is attached to the roller.
  • the window shade of this invention has many of the advantages from a commercial point of view that are set forth in U.S. Pat. No. 3,203,468, the disclosure of which is incorporated herein by reference.
  • FIG. 1 The components of the preferred embodiment of the present invention are illustrated in FIG. 1.
  • a shade roller that is made in two telescoping sections.
  • the tubular first roller section 11 preferably is made of sheet metal and it includes the usual spring motor, not shown.
  • the second roller section 12 may comprise a wooden dowel that fits snugly into the open end of the tubular first roller section 11.
  • Two elongated dimples 13-13 are formed in the wall of the tubular first roller section 11, these dimples are friction elements, biting into the wood dowel comprising second roller section 12.
  • the second roller section 12 may have the spring motor mounted within it.
  • a first tube 14 of readily cuttable material such as paper or plastic is provided that is adapted to slide over the second roller section and it is of a length to abut the one end of the first roller section 11 and extend to the adjacent end cap 15 for the roller.
  • This end of the roller also carries a conventional gudgeon pin 16 whereas the opposite end of the roller has the usual flat spear 17 by which the assembly may be mounted in conventional window shade brackets.
  • the elements described to this point are identical to their counterparts in U.S. Pat. No. 3,203,468.
  • first tube 14 With first tube 14 in place on the second roller section 12, the subassembly thus formed is of the same diameter throughout its length, excepting the end caps of the roller.
  • three rubber bands 18 are provided. There rubber bands are engaged around the first roller section 11 in spaced relation along its length. The rubber bands are of a diameter such that they tend to grip the outer surface of the first roller section when in place upon it.
  • second tube 19 of readily cuttable material such as paper, light cardboard, plastic or the like. One end of second tube 19 is serrated longitudinally as shown at 20 for reasons to be explained later.
  • first tube 14 is slipped over the exposed end of second roller section 12, the rubber bands 18 placed on first roller section 11, and second tube 19 slid into place such that it surrounds and is coextensive with first roller section 11 and first tube 14.
  • the rubber bands 18 are interposed between the inner surface of second tube 19 and the outer surface of first roller section 11.
  • the second tube is slipped into place starting over end cap 15.
  • the rubber bands provide a means of permitting relative longitudinal shifting movement between second tube 11 and the subassembly which it encloses while, for all practical purposes, preventing any relative rotational movement between second tube 19 and said subassembly.
  • FIG. 1 A typical shade is shown fragmentarily only in FIG. 1 designated generally by the numeral 21. As shown, this shade has a transversely symmetrical design in the form of a sealloped lower edge 22. The lower edge 22, as shown, may have decorative fringe 23 on it.
  • the usual slat pocket, shown here at 24, is formed to extend across the shade a slight distance above the scalloped lower edge. The usual wooden slat (not shown) is carried within pocket 24.
  • the upper end of shade 21 has a line of adhesive 25 on it by means of which the shade may be attached to second tube 19. Thus, the only attachment of the shade to the roller assembly is on second tube 19.
  • an end cap 26 at the motor end of the window shade is employed that is slightly larger in diameter that first roller section 11, and in order to remove the free end of second tube 19 and the roll of shade material wound on it, a pointed instrument may be used to split the serrations 20 at this end of second tube 19 so that the freed end of the tube may be slipped from the end of the roller over end cap 26.
  • the first cutting operation leaves a projecting end of the first roller section 11 as shown by the dot-dash lines 27 in FIG. 3. Also shown in this figure is the rolled up, waste cut end 28 of shade material wound around the cut end 29 of second tube 19. The split in the cut end of second tube 19 permitted by serrations 20 is shown at 30.
  • the next cutting operation is at the opposite or right end of the window shade as shown in FIG. 3, the out being made along the line 31.
  • the cut is made down through the shade material and through first tube 14.
  • the rolled up waste shown at 32 may be slipped off the end of the roller over cap which, in this instance, is equal in diameter to the second roller section 12 so that serrations of the type shown at are not necessary in this end of second tube 19.
  • serrations 20 may be duplicated at this end of second tube 19 and in the first tube 14, if desired.
  • This invention permits the removal of equal amounts of shade material from opposite ends of the window shade in order to preserve the overall symmetry of the design in the scalloped lower edge of the shade itself.
  • the symmetry of other designs may be preserved in the same way. It will be apparent, however, that the shortening operation may be made by cutting material from one end, i.e. either end, only of the window shade, when preserving design symmetry is not required.
  • first tube 14 it is not necessary to utilize first tube 14 in the finished assembly and this type of shade construction is shown in FIG. 5.
  • a cutting operation may proceed as described above wherein it is desired to preserve design symmetry. if one end only is to be cut, and it makes no difference which end, shortening of the roller itself is a result of telescoping the second roller section 12 into the first roller section 11; whereas the relative shifting movement, to bring the two end caps into their proper positions with respect to the rolled up shade, is a result of the rolling movement permitted by the rubber bands 18.
  • means other than the rubber bands 18 may be employed so long as the means has the characteristic of permitting relative longitudinal shifting movement between first roller section 11 and second tube 19 while preventing relative rotational movement between these two parts.
  • first roller section being tubular
  • 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;
  • 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 andsaid 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.
  • said friction means comprises at least one rubber band seated on and extending circumferentially around said first roller section.
  • first roller section being tubular
  • 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;
  • 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;
  • the roller 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.
  • said friction means comprises at least one rubber band seated on and extending circumferentially around said first roller section.
