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

摘要翻译： 窗罩具有多个遮光元件，每个遮光元件具有第一纵向边缘和第二纵向边缘。 遮光元件顺序地位于头轨下方，并且每个遮光元件由围绕第一纵向边缘滚动的窗户覆盖材料制成。 第一轨道从头轨延伸穿过每个遮光元件的第一纵向边缘并且连接到最下面的遮光元件或底部导轨。 第二轨道从头轨延伸并且附接到最下面的阴影元件或底部轨道并连接到每个阴影元件的第二纵向边缘。 梯级在第一轨道和第二轨道之间延伸，使得在每个阴影元件下方具有一个梯级并对应于该梯级。 当遮盖物处于关闭位置时，每个遮光元件的第一纵向边缘搁置在相应的梯级上。 控制机构连接到第一轨道并且能够相对于第二轨道移动第一轨道。 这种相对运动导致多个遮光元件中的每一个围绕遮光元件的第一纵向边缘滚动或展开。
