ABSTRACT:
A window shade mounting assembly includes at least one tubular formation or channel extending substantially the width of a window shade proximate and parallel to an upper end or edge thereof for receiving a curtain rod and cooperating therewith to support the window shade in opposition to the force of gravity. The mounting assembly also includes a plurality of pulleys each having on one side and on a lower end a rotatably mounted roller and, on an end and a side of the pulley opposite the roller, a hook shaped mounting element which is insertable through apertures in the tube of the window shade and which can be snapped onto the curtain rod. The pulleys support cords or strings which are connected to a lower end of the window shade for alternately raising and lowering that lower end in response to manipulations by an operator.
