Claim 12

A venetian blind installation as in claim 6 wherein the improvement further comprises: a third series of slats, located below the second series, which controls the passage of light through a rectangular area, the slats of the first series have one of their ends bunched together and have the other of their ends spaced apart and vertically aligned, the slats of the second series have one of their ends vertically aligned with the spaced-apart ends of the slats of the first series, the slats of the second series have the other of their ends in stepped formation with the longest slat at the bottom, and the slats of the third series have one of their ends vertically aligned with the spaced-apart ends of the slats of the first series.

Claim 13

A venetian blind installatiOn as in claim 6 wherein the improvement further comprises: the blind is installed at a window that has an inclined soffit, the blind includes a head which is mounted at an inclination corresponding to the inclination of the soffit, a plurality of ladders of different length hang vertically from the head, and each of the two series of slats is supported by these ladders.

Claim 14

A venetian blind installation as in claim 7 wherein the improvement further comprises: a third series of slats, located below the second series, which controls the passage of light through a rectangular area, the blind is installed at a window that has an inclined soffit, the blind includes a head which is mounted at an inclination corresponding to the inclination of the soffit, at least three ladders of different length hang vertically from the head, the first and second series of slats are each supported by at least two of the ladders neither of which is the shortest ladder, and the third series of slats is supported by the shortest ladder and also by at least one of the ladders that supports the first and second series of slats.

Claim 15

A venetian blind installation as in claim 11 wherein the improvement further comprises: the blind includes means to raise and lower slats of the third series of slats.

Claim 16
