A retractable cover for architectural openings having collapsible vanes includes a support structure in the form of a sheet of material, monofilaments, tapes, ribbons, cords, or the like, supporting an upper edge of a plurality of vertically spaced, horizontally extending vanes with the lower edges of the vanes in most embodiments of the invention being connected to operating elements adapted to raise the lower edges of each vane toward the upper edges to define openings or gaps between the vanes through which vision and light can pass in an open condition of the covering. Variations of the covering do not require movement of a lower edge of a vane relative to an upper edge but simply movement of some vanes relative to other vanes. The vanes can be made of materials having different flexibilities and where more rigid materials are used, creased fold lines can be established for desired operability.

1. A panel for use in a covering for an architectural opening comprising: a sheet structure having a length;a plurality of flexible elements disposed in a parallel relationship in a common plane extending along said length of said support sheet,a plurality of attachment strips positioned between said sheet structure and said plurality of flexible elements, anda plurality of strips of fabric, said strips of fabric being secured to said attachment strips along lines of attachment at a bottom portion of said plurality of strips of fabric with said flexible elements disposed therebetween such that said attachment strips connect said plurality of strips of fabric to said flexible elements and not to said sheet structure. 2. The panel of claim 1 wherein less than all of said flexible elements are secured to said attachment strips and strips of fabric along said lines of attachment. 3. The panel of claim 2 wherein the flexible elements that are not secured to said attachment strips and strips of fabric along said lines of attachment are slidable relative to said attachment strips and strips of fabric across said lines of attachment. 4. A covering for an architectural opening movable between extended and retracted positions comprising in combination: a panel of vertically extendable, flexible material having an upper edge and a lower edge;a headrail including a roller about which the panel of material can be wrapped, said upper edge of the panel being secured to the periphery of said roller;said panel including a support structure and a plurality of horizontally extending strips of material supported thereon, said strips each having an upper edge secured to said support structure and a movable lower edge and a plurality of operative elements secured to said lower edge of the strips of material and to said roller to selectively move said lower edge of said strips toward the upper edge; and a bottom rail including a curvilinear surface and further including an attachment element operatively secured to said operative elements and extending around said curvilinear surface whereby said attachment element is positioned around said curvilinear surface and said curvilinear surface moves between a first position and a second position with respect to the support structure as said lower edges of said strips are moved toward the upper edges of said strips. 5. The panel of claim 1 wherein said elements are monofilaments. 6. The panel of claim 1 wherein said elements are strips of material. 7. The panel of claim 1 wherein said elements are cords of natural fibers.
