Window covering having roll-up shade segments

摘要

A window covering (1) has a plurality of shade elements, each having a first longitudinal edge (21) and a second longitudinal edge (22). The shade elements (20) are positioned sequentially below a headrail (6), and each shade element is made of a window covering material that can be rolled about the first longitudinal edge (21). A first rail (11) extends from the headrail (6) past the first longitudinal edge (21) of each shade element (20) and is connected to lowermost shade element or the bottom rail. A second rail (12) extends from the headrail (6) and is attached to lowermost shade element or the bottom rail and to the second longitudinal edge (22) of each shade element. Rungs (10) extend between the first rail (11) and the second rail (12) such that there is one rung (10) below and corresponding to each shade element (20). The first longitudinal edge (21) of each shade element rests upon a corresponding rung (10) when the window covering is in a closed position. A control mechanism (17) is connected to the first rail (11) and is capable of moving the first rail relative to the second rail (12). Such relative movement causes each of the plurality of shade elements to roll or unroll about the first longitudinal edge (21) of the shade element.
