Abstract:
1. A window blind system, comprising: a top traverse supporter; a first shading arrangement, which is downwardly extended from said top traverse supporter, comprising a base member, a plurality of slats, a first hanging system which is adapted for spacedly and suspendedly supporting said slats horizontally disposed between said top traverse supporter and said base member and for selectively rotating an angle of said slats, and a first operating system for selectively lifting up said base member towards said top traverse supporter and unlifting said base member to drop downwardly away from said top traverse supporter; wherein said first shading arrangement comprises a traverse arm rotatably mounted to said top traverse supporter, at least two elongated hanging nets vertically extended from two ends of said traverse arm for suspendedly supporting said slats and said base member, wherein each of said elongated hanging net comprises a first and second supporting cords extended from two ends of said traverse arm to said base member, and a plurality of traverse cords spacedly extended between said two supporting cords to form a plurality of vertically and consecutively arranged first hanging grids, wherein said slats are positioned between said two supporting cords and separated by said first hanging grids; wherein said first operating system comprises a lift lock rotatably mounted on said top traverse supporter and a lift cord having an end fastened to said base member, and another end upwardly extended to penetrate through said slats to reach said top traverse supporter, wherein said lift cord is exited from said top traverse supporter via said lift lock to control a folding process of said first shading arrangement; and a second shading arrangement, which is downwardly extended from said top traverse supporter, comprising a second hanging system which is adapted for spacedly and suspendedly supporting a predetermined set of said slats horizontally disposed between said top traverse supporter and said base member, and a second operating system for lifting up said second hanging system towards said top traverse supporter and unlifting said second hanging system to drop downwardly away from said top traverse supporter, so that by operating said second operation system, said predetermined set of said slats are capable of being lifted with respect to remaining said slats thus creating a varying shading status; wherein said shading arrangement comprises at least two elongated second hanging nets vertically extended from two ends of said traverse arm to said base member for supporting said predetermined set of said slats, wherein each of said second hanging nets comprises a pair of elongated strings, and a plurality of traverse strings spacedly extended between said pair of elongated strings to form a plurality of vertically and consecutively arranged second hanging grids for supporting said predetermined set of said slats.
