Covering assembly for architectural openings

A covering for use in a light control covering assembly for an architectural opening, said covering comprising:

• i) first and second generally parallel spaced apart, longitudinally extending, sheer fabrics, each having a top edge portion and a bottom edge portion;
• ii) a plurality of longitudinally spaced, generally parallel, vertically extending soft vanes, fixedly secured to said first and second sheer fabrics to extend therebetween;
• and
• iii) said fabrics and said vanes defining a series of panels composed of a vane and the associated portions of the fabrics, said covering being intended for covering an opening by extending said panels to a vertically planar orientation wherein the panels can be manipulated to tilt the vanes between a closed position parallel to said fabrics and an open position generally normal to said fabrics to obtain light control and wherein each sheer fabric has dimensional stability in substantially mutually perpendicular directions inclined to the vertical.

A light control shade assembly comprising in combination;

• a) a shade member having an upper edge portion and comprising:
• i) first and second generally parallel spaced apart, vertically extending translucent sheets, at least one of said sheets having dimensional stability in substantially mutually perpendicular directions inclined to the vertical;
• ii) a plurality of longitudinal, parallel spaced vertically extending soft vanes, fixedly secured with their opposite longitudinal edges to said first and second sheets to extend therebetween;
• b) carrier means connected to said shade member to suspend said shade member in an extended vertically planar condition in which said shade member is effective in shading a predetermined area and in which condition the vanes can be manipulated to alter their orientation between a closed position parallel to said first and second sheets and an open position generally perpendicular to said first and second sheets to obtain light control in the shaded area.

A light control covering assembly comprising in combination:

• a) a covering comprising:
• i) first and second generally parallel spaced apart, longitudinally extending, sheer fabrics, each having a top edge portion and a bottom edge portion, at least one of said sheer fabrics having dimensional stability in substantially mutually perpendicular directions inclined to the vertical;
• ii) a plurality of longitudinally spaced, generally parallel, vertically extending, soft vanes, fixedly secured to said first and second sheer fabrics to extend therebetween;
• and
• iii) said fabrics and said vanes defining a series of panels composed of a vane and the associated portions of the fabrics;
• b) a track;
• and
• c) carrier means riding in said track between a spread condition and a stacked condition and being connected to said top portions of said panels for extending said panels to a vertically planar orientation in which said covering covers an opening when the carrier means are in the spread condition, and in which spread condition the panels can be manipulated to tilt the vanes between a closed position substantially parallel to said fabrics and an open position generally normal to said fabrics to obtain light control, whereby said vanes do not generally twist when tilted.
