Abstract
A venetian type window covering has substantially flat front and back layers made of transparent or translucent materials and preferably different sheer fabrics. The space between these layers is spanned by bridges at regular intervals slightly smaller than the space. The bridges are made of strips of material or bands of single or double strands that support slats that can be easily inserted or removed by the consumer. The slats may be flexible or ridged and are restrained from moving laterally by slots in their front and back edges that cords pass through. The cords have tension on them at all times and thereby retain the slats. The slats may also be retained by folding over the ends of the slats around the bridges.
Claims40
A material structure comprising:
- at least one front section of material;
- at least one rear section of material;
- a plurality of discrete lengths of strands having a selected length wherein said strand lengths are adhered at one end to said at least one front section of material and adhered at an opposite end to said at least one rear section of material;
- and
- a plurality of slats each slat positioned on at least one discrete length of strand.
A material structure comprising:
- at least one front section of material having at least one transverse edge;
- at least one rear section of material having at least one transverse edge, wherein said at least one transverse edge of the second section of material faces a respective one of said at least one transverse edge of said front section of material;
- a plurality of discrete lengths of strands having a selected length for connecting said at least one edge of said at least one front section of material to a respective one of said at least one edge of said at least one rear section of material;
- and
- a plurality of slats, each slat positioned on at least one discrete length of strand.
A window covering structure comprising:
- an elongated sheet of first pleated material having a selected length and having a plurality of transverse pleats, the pleats being alternately directed in opposite directions to one another so as to have a series of inward pleats disposed on one side of the first sheet of material and having a series of outward pleats disposed on an opposite side thereof;
- an elongated sheet of second pleated material having a selected length and having a plurality of transverse pleats, the pleats being alternately directed in opposite directions to one another so as to have a series of inward pleats disposed on one side of the second sheet of material facing the inward pleats of the first sheet of material and having a series of outward pleats disposed on an opposite side of the second sheet of material;
- a plurality of elongated slats, each slat having opposite face surfaces, a first end and a second end, each slat being positioned between the sheet of first material and the sheet of second material;
- a plurality of first and second connecting portions to which the first sheet and the second sheet are respectively attached, each first connecting portion being connected to the first end of each slat, and each second connecting portion being connected to the second end of each slat;
- a plurality of first and second hinges, each pair of first and second hinges pivotably connecting each slat to the first and second connecting portions, respectively, each first hinge being disposed between each first connecting portion and each slat, and each second hinge being disposed between each second connecting portion and each slat;
- and
- a plurality of second slats, each of the second slats placed on one of the plurality of elongated slats, wherein when the sheet of first material and the sheet of second material are positioned relative to one another such that when the structure is in an open position, the plurality of elongated slats are spaced apart and the face surfaces of each elongated slat are substantially parallel to one another and substantially perpendicular to the length of the first material and the second material, and when the structure is moved to a closed position, the elongated slats move so as to have the face surfaces of each elongated slat being generally aligned with one another on a common plane that is substantially parallel to the length of the first material and the connecting portions are substantially perpendicular to the plane of the slats and wherein the structure retains a cellular configuration in both the open and closed positions.
