Abstract
A window covering is described wherein at least one translucent or transparent sheet is suspended vertically and has a plurality of parallel vanes projecting rearwardly therefrom. The vanes are formed from fabric material which has either been rigidified with a rigidifying compound or rigidified by the formation of a pocket into which a rigid slat is inserted. Variations are provided for varying the flexibility of a hinge defined along a juncture line between the vanes and the fabric sheet.
Claims23
A window covering comprising in combination, a flexible sheet of fabric material having a front face and a rear face, a plurality of parallel elongated fabric vanes having a longitudinal axis and forming variably directed flexible extensions from said rear face of said sheet, said fabric vanes having a stiffening compound impregnated into the fabric whereby said vanes retain a predetermined form, and control means for operably supporting said vanes and said sheet such that said sheet is suspended substantially vertically and for pivoting said vanes about said longitudinal axes so as to shift said window covering between an open condition wherein said vanes extend substantially perpendicularly to said sheet and a closed position wherein said vanes extend substantially parallel to said sheet.
A window covering comprising in combination, a flexible sheet of fabric material having a front face and a rear face, a plurality of parallel elongated fabric vanes having longitudinal axes, said vanes comprising loops of material formed from said sheet of material off the rear face of said sheet and substantially rigid slats confined in said loops of material, said loops of material having two spaced confronting layers which are secured together along a hinge line adjacent to said rear face of said sheet at the juncture of said vanes with said sheet, and a control system for operably supporting said vanes and sheet such that said sheet is suspended substantially vertically and for pivoting said vanes about said longitudinal axes so as to shift said window covering between an open condition wherein said vanes extend substantially perpendicularly to said sheet and a closed position wherein said vanes extend substantially parallel to said sheet.
A window covering comprising in combination first and second continuous flexible sheets of fabric material extending substantially parallel to each other with each having a front face and a rear face, the front face of said second sheet confronting the rear face of said first sheet, a plurality of parallel elongated vanes, said vanes comprising loops of material integrally formed from one or the other of said sheets of material and extending from the front face of said second sheet or the rear face of said first sheet toward the other of said sheets, and substantially rigid slats confined in said loops of material, said loops of material having two spaced confronting layers which are secured together along a hinge line adjacent to the sheet from which it is integrally formed and an edge opposite said hinge line flexibly connected to the sheet from which the vane is not integrally formed.
A window covering comprising in combination first and second flexible sheets of fabric material extending substantially parallel to each other with each sheet having a front face and a rear face, the front face of said second sheet confronting the rear face of said first sheet, a plurality of parallel elongated vanes, said vanes comprising independent elongated loops of fabric material and substantially rigid slats disposed within said loops, each vane having opposite side edges respectively flexibly connected to the front face of said second sheet and the rear face of said first sheet.
