Control system for vertical covering for architectural openings
Abstract:
A covering for an architectural opening includes a fabric adapted to be extended across the opening or retracted adjacent one side of the opening. The fabric has one fixed edge along one side of the opening and an opposite movable edge. The movable edge is guided by a flexible metal tape disposed in a generally Z-shaped configuration that extends slidably along the movable edge of the fabric and in opposite perpendicular directions at opposite ends of the movable edge for variable lengths.
