ABSTRACT:
A window covering including first and second sheer fabrics interconnected by a plurality of transversely extending vanes is disclosed. The sheer fabrics are connected to circumferentially spaced apart fixing elements on a wind up roll which is mounted with its longitudinal axis extending generally horizontally to one side of a frame of a skylight. Associated with the wind up roll at each end are cord reels and a control pulley at one end of a respective cord reel. Rotation of the wind up roll is effected by operation of a cord wrapped around the control pulley. Wrapped around the cord reels are tension cords which pass around fixed pulleys and are connected to opposite ends of an end rail having in its interior a tension spring to the end of which are attached the ends of the tension cords. Two parallel tracks extending generally perpendicular to the wind up roll is provided for guiding the end rail.
