Abstract
Abstract A window covering system is disclosed herein which provides an attractive drape-like appearance and further provides the brightness control of louvers. The system uses conventional vertical blind hardware employed with vertically disposed louvers which is capable of actuating such louvers to provide both a varying angular orientation of the louvers relative to the traverse rod and a means for retracting the louvers from in front of the window. Drape material is hung from the vertically disposed louvers. The drape material is attached to the louvers in such a way that a normal drape-like effect is obtained regardless of the angular orientation of the louvers. This drapelike effect may also be achieved without pinch pleating the drapery material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A decorative window covering system comprising: a vertical blind mechanism, vertically disposed louvers pivotally mounted to said vertical blind mechanism and dependent therefrom, said vertical blind mechanism providing selective angular orientation of said louvers with respect to said vertical blind mechanism, and flexible covering material attached to each of said louvers, said flexible covering material being constrained to move with said louvers when said louvers are moved laterally on said vertical blind mechanism, said flexible covering material freely depending from near the upper ends of said vertically disposed louvers to create a drape-like covering, said flexible covering material including a free length thereof between louvers to create a drapery-like effect.
Claim 2
Dependent Claim
110 words
A decorative window covering system comprising: a vertical blind mechanism, vertically disposed louvers pivotally mounted to said vertical blind mechanism and dependent therefrom, said vertical blind mechanism providing selective angular orientation of said louvers with respect to said vertical blind mechanism, and flexible covering material attached to each of said louvers, said flexible covering material being constrained to move with said louvers when said louvers are moved laterally on said vertical blind mechanism, said flexible covering material freely depending from near the upper ends of said vertically disposed louvers to create a drape-like covering, said flexible covering material including a free length thereof between louvers to create a drapery-like effect.
Claim 3
Dependent Claim
110 words
A decorative window covering system comprising: a vertical blind mechanism, vertically disposed louvers pivotally mounted to said vertical blind mechanism and dependent therefrom, said vertiCal blind mechanism providing a selective angular orientation of said louvers with respect to said vertical blind mechanism, and flexible covering material attached to each of said louvers, said flexible covering material being constrained to move with said louvers when said louvers are moved laterally on said vertical blind mechanism, said flexible covering material hanging from near the upper ends of said vertically disposed louvers to create a drape-like covering, said flexible covering material including a free length thereof between louvers to create a drapery-like effect.
Claim 4
Dependent Claim
110 words
A decorative window covering system comprising: a vertical blind mechanism, vertically disposed louvers pivotally mounted to said vertical blind mechanism and dependent therefrom, said vertiCal blind mechanism providing a selective angular orientation of said louvers with respect to said vertical blind mechanism, and flexible covering material attached to each of said louvers, said flexible covering material being constrained to move with said louvers when said louvers are moved laterally on said vertical blind mechanism, said flexible covering material hanging from near the upper ends of said vertically disposed louvers to create a drape-like covering, said flexible covering material including a free length thereof between louvers to create a drapery-like effect.
Claim 5
Dependent Claim
25 words
The decorative window covering system of claim 2, wherein said flexible covering material is attached across at least one width of each of said louvers.
Claim 6
Dependent Claim
28 words
The decorative window covering system of claim 2, wherein said flexible covering material is caused to overlap itself to provide a drapery-like appearance having varying degrees of translucency.
Claim 7
Dependent Claim
