摘要:
A covering for an architectural feature having generally horizontal vane elements extending between generally inner and outer vertical support members that can adjust and control the amount and quality of light transmitted through the covering is described. In one embodiment, the covering has elongate tapes as vertical support members that have a width substantially less than the length of the vane elements, and adjacent inner and adjacent outer elongate tapes are separated by a distance. In one embodiment, the vane elements are multi-layered, cellular vanes. The elongated multilayered vanes may include elongate stiffeners that may be associated with, coupled to, and or inserted within pockets formed in, the multilayered vanes. Also disclosed is a method of operation and manufacture.
摘要:
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.
