Abstract
The present invention is directed to a shading system in which the shade cord and the winding coil spring are coaxially arranged along a winding shaft or hub for the shade cord. Additionally, the pair of end supports supporting the shade or shade roller or tube are provided with a series of horizontally-extending slots so that the shading device can be arranged to hang in directions other than just straight down from the mounting shade tube.
