Abstract

A window blinding system includes a top traverse supporter adapted for affixing to a top beam of a ceiling, a first shading arrangement, and a second shading arrangement. The first shading arrangement includes a first base member, a plurality of first slats, a first blind supporting system for spacedly and suspendedly supporting the first slats horizontally between the top traverse supporter and the first base member, and a first operating system for selectively lifting up and dropping down the first base member towards and from the top traverse supporter. The second shading arrangement includes a plurality of second slats and a second blind supporting system for spacedly and suspendedly supporting the second slats horizontally between the first slats. Therefore, by selectively adjusting positions of the first and second slats, the first and second shading arrangements are capable of providing multiple shading effects.
