Abstract
Abstract A Venetian blind is described having slats which have a selected color on one face and a lighter neutral, pastel or substantially white color on the reverse face, with string type ladders, one string of each ladder being colored to blend with the darker colored faces of the slats and the other string thereof being of the lighter color to blend with the lighter colored face of the slats. The cross rungs are also longitudinally colored in part in the same color as the darker colored string and the lift cord is of the same color as the darker colored string, so that when the blind is in the closed or partially closed position with the darker colored faces of the slats on one side of the blind, the strings of the ladders and lift cords blend with the colored surfaces of the slats on that side and are substantially unnoticeable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
287 words
A Venetian blind comprising an upper supporting housing having means for independently tilting and elevating a plurality of slats having concave and convex surfaces suspended therebeneath on ladders, each ladder being provided with two vertical braided strings, one disposed on the inside and the other on the outside of the slats and string-like cross-rungs connected to the respective strings for supporting the slats, the ladder terminating in a bottom bar; each slat being provided with slots for receiving a lift cord, a light colored surface on one face thereof and a contrasting darker colored surface on the other face thereof; the vertical strings of the ladders on one side of the blind being of a light color substantially blending with the light colored surfaces of the slats and the vertical strings of the ladder on the other side of the blind being of the contrasting darker color to blend with a similar color on the other surfaces of the slats; the cross-rungs connecting the respective strings of each ladder also being of the same contrasting darker color extending from the darker colored string up to from about one/half to three/quarters the length of each cross-rung; and a lift cord of the same darker contrasting color passing through the slots in the slats; whereby when the blind is in the closed and partially closed positions with the darker contrasting colored surfaces on one side of the slats with the lighter colored surfaces on the other side thereof the darker vertical strings of the ladders and the lift cord will be substantially unnoticeable and blend with the darker colored surfaces of the slats and the lighter strings of the ladder will blend with the lighter surfaces of the slats.

A Venetian blind comprising an upper supporting housing having means for independently tilting and elevating a plurality of slats having concave and convex surfaces suspended therebeneath on ladders, each ladder being provided with two vertical braided strings, one disposed on the inside and the other on the outside of the slats and string-like cross-rungs connected to the respective strings for supporting the slats, the ladder terminating in a bottom bar; each slat being provided with slots for receiving a lift cord, a light colored surface on one face thereof and a contrasting darker colored surface on the other face thereof; the vertical strings of the ladders on one side of the blind being of a light color substantially blending with the light colored surfaces of the slats and the vertical strings of the ladder on the other side of the blind being of the contrasting darker color to blend with a similar color on the other surfaces of the slats; the cross-rungs connecting the respective strings of each ladder also being of the same contrasting darker color extending from the darker colored string up to from about one/half to three/quarters the length of each cross-rung; and a lift cord of the same darker contrasting color passing through the slots in the slats; whereby when the blind is in the closed and partially closed positions with the darker contrasting colored surfaces on one side of the slats with the lighter colored surfaces on the other side thereof the darker vertical strings of the ladders and the lift cord will be substantially unnoticeable and blend with the darker colored surfaces of the slats and the lighter strings of the ladder will blend with the lighter surfaces of the slats.
