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. An additional layer may be provided opposite the front face or the back face.

Claims

1. A honeycomb comprised of a front face, a back face and a plurality of slats attached therebetween wherein:

the front face is comprised of a plurality of parallel threads spaced apart a sufficient amount so as to allow light to pass through the front face, the front face having not more than one cross thread intersecting the plurality of parallel threads for every ten parallel threads;

the back face is comprised of a plurality of parallel threads spaced apart a sufficient amount so as to allow light to pass through the front face; and

the slats are comprised of a material that is opaque or nearly opaque.

2. The honeycomb of claim 1 also comprising cross threads in the back face.

3. The honeycomb of claim 2 wherein the cross threads and the spaced apart parallel threads form a knit material or a woven material.

4. The honeycomb of claim 1 wherein the material of the slats are selected from the group consisting of wood, metal, plastic, textile and composite materials.

5. The honeycomb of claim 1 wherein the slats are comprised of a flexible material.

6. The honeycomb of claim 1 wherein the slats are comprised of a rigid material.

7. The honeycomb of claim 1 also comprising at least one stiffener attached to at least one of the slats, the at least one stiffener being a longitudinal stiffener or a transverse stiffener.

8. The honeycomb of claim 1 also comprising at least one of a headrail, a bottomrail and a roller attached to the front face and the back face to form one of a horizontal shade, a vertical shade, and a roller shade.

9. The honeycomb of claim 1 also comprising at least one lift cord routed through the honeycomb.

10. The honeycomb of claim 9 wherein the at least one lift cord is positioned within a space between two adjacent parallel threads in one of the front face and the back face.

11. The honeycomb of claim 9 also comprising a loop attached to each slat for each of the at least one lift cord and that lift cord passes through each such loop.

12. The honeycomb of claim 1 also comprising at least one cross thread woven through the parallel spaced threads in the front face, the number of cross threads being not more than one tenth as many as the plurality of parallel threads in the front face.

13. The honeycomb of claim 12 wherein the at least one cross thread forms a decorative pattern.

14. The honeycomb of claim 1 wherein the slats have been attached to at least one of the front face and the back face at spaced apart locations on each slat.

15. The honeycomb of claim 1 also comprising at least one cross thread woven through the parallel spaced threads of the back face, the number of cross threads being not more than one tenth as many as the plurality of parallel threads in the back face.

16. The honeycomb of claim 1 wherein the plurality of parallel threads in the front face are spaced apart a distance from 0.08 inches to 0.25 inches.

17. The honeycomb of claim 1 wherein the plurality of parallel threads in the back face are spaced apart a distance from 0.08 inches to 0.25 inches.

18. The honeycomb of claim 1 also comprising a mandrel to which the front face and the back face are attached.

19. The honeycomb of claim 1 also comprising:

a. a headrail attached to the honeycomb at one end;

b. a bottomrail attached to the honeycomb at an opposite end; and

c. at least one lift cord extending from the bottomrail into the headrail.

20. The honeycomb of claim 19 wherein the bottomrail is comprised for a first rail attached to the front face and a second rail attached to the back face.

21. The honeycomb of claim 19 also comprising at layer of material extending from the headrail and positioned opposite one of the front face and the rear face.

22. The honeycomb of claim 20 wherein the layer of material is connected to the at least one lift cord.

23. The honeycomb of claim 20 also comprising at least one additional lift cord attached to the layer of material and extending from the headrail.

24. The honeycomb material of claim 20 also comprising a second bottomrail attached to the layer of material.
