Abstract:
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.
Abstract:
Methods and apparatus to control an architectural opening covering assembly are disclosed herein. An example method disclosed herein includes determining a position of a covering of an architectural opening covering assembly. The example method further includes determining a speed at which the covering is to move via a motor based on the position and a period of time. The example method also includes operating a motor to move the covering at the speed.
