  • Patent number: 5127459
    Abstract: The present invention provides a readily adjustable rod for a tear-away window shade. The shade is constructed of a long sheet of a rollable material provided with a multiplicity of longitudinally disposed parallel tear lines spaced apart from each other in the widthwise direction to define a multiplicity of strips. The window shade rod includes a multiplicity of disconnectable segments. Strips of the sheet can be individually torn away at the tear lines from the ends of the sheet so as to decrease the width of the shade in decrements corresponding to the width of the strips. Segments can be removed from the rod so that the rod width can be decreased to correspond to the width of the sheet.

  • Patent number: 4539238
    Abstract: A window shade comprises a multiplicity of elongate fabric strips connected to one another along their longitudinal edges by means of severable connecting threads. Mounting and weighting rods inserted in respective pockets at the upper and lower end of the multistrip fabric web are adjustable in length to match the width of the window shade upon a reduction thereof owing to a tearing of one or more fabric strips from the body of the window shade web. The window shade web is advantageously provided with a foam backing which contributes in part to the mechanical stability of the shade.
