Abstract:
1. A rollup covering for architectural openings comprising in combination: an elongated head rail having opposed longitudinally extending grooves, a roller and a control system for effecting reversible rotation of said roller, a flexible material having an upper edge secured to said roller and a lower edge secured to a bottom rail, said material being wound about said roller in a retracted position of the covering and unwound from said roller in an extended position of the covering, and a skew adjustment device slidably mounted within said head rail that releasably adjusts its position along the longitudinal length of the head rail and compressibly engages said material when said material is at least partially wound about said roller with sufficient compressive force to maintain a horizontal orientation of said bottom rail, said device including a generally planar body with top and bottom edges slidably received in said grooves and compressible between said edges and a resilient arm operatively connected to said body and positioned to compress said flexible material at a predetermined location.
