ABSTRACT:
A window covering has a headrail, a plurality of lift cords extending from the headrail and a plurality of shade elements positioned sequentially below the headrail. Each shade element has an upper edge and a lower edge which edges are substantially parallel to one another and oriented transverse to the lift cords. The shade elements are positioned so that when the shade elements are in a closed position the lower edge of one shade element abuts the upper edge of an adjacent shade element and when the shade elements are in an open position, the lower edge of the at least one shade element is spaced apart from the upper edge of an adjacent shade element. A first cord is attached to the upper edge of each shade element and a second cord is attached to the lower edge of each shade element. These cords extend to or into the headrail and allow the upper edge of one or more shade elements and the lower edge of an adjacent shade element to be moved away from one another to create a gap between adjacent shade elements through which light may pass. In one embodiment these cords are in a common plane. In another embodiment the first cord is spaced apart from the second cord at a distance less than the width of the shade segments. The window covering may be configured for top down, bottom up operation.
