    • 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.
    • 公开了一种包括由多个横向延伸叶片相互连接的第一和第二透明织物的窗口覆盖物。 整体织物在卷绕辊上连接到周向间隔开的固定元件,该卷绕辊的纵向轴线大致水平地延伸到天窗框架的一侧。 与每个端部的卷绕辊相关联的是帘线卷轴和在相应的帘线卷轴的一端的控制带轮。 卷绕辊的旋转通过缠绕在控制滑轮上的绳索的操作来实现。 围绕绳索卷绕的是张力绳,其通过固定的滑轮并且连接到端部轨道的相对端,在其内部具有拉伸弹簧,其端部附接到张力帘线的端部。 提供了大致垂直于卷取辊延伸的两个平行轨道,用于引导端轨。
