Abstract: A slatted blind is configured such that the slats close create a light blocking blind. The slats may be supported by a tilt cord that comprises a low stretch strand or a low stretch cord may be attached to the tilt cord. The slats may be connected to the supporting tilt cord such that when the slat is rotated to a closed position the slat is suspended from the rung. The rung may have an effective diameter of less than approximately 14 mil. Recesses may be formed in the slat for receiving the rung when the slat is in a closed position. A bottom rail may have a thickness approximately equal to the thickness of the slats. A protrusion may be formed on the back of the slats such that the rung pushes on the protrusion to force the slat against an adjacent slat when the blind is closed.

Abstract: A light controllable window covering has a transparent front face and a transparent back face, either or both of which are formed from a series of spaced apart parallel threads, and a series of opaque slats attached between the two faces. The parallel threads which form the front face and back face are spaced apart an amount which allows light to readily pass while providing a soft fabric like appearance. The slats are preferably knitted or woven fabric treated to have a given light impeding property. The front and back longitudinal edges of each slat are respectively attached to the front face and the back face. The resulting structure when combined with a hardware system is a light control honeycomb window covering. Movement of the light impeding slats from a position perpendicular to the front face and back face to a position generally parallel to the front and back face controls the amount of light which is admitted through the window covering.
