Abstract

A honeycomb structure particularly useful for window coverings is made by simultaneously knitting or weaving a front sheet, a rear sheet and a plurality of webs therebetween. A warp knitting process is used to make the front sheet and rear sheet. At least one warp thread from one sheet is threaded through the opposite sheet to form the webs. Preferably, a wood, metal, textile or plastic slat is placed on each web.

Claims

1. A method of making a honeycomb comprising the steps of:

a) providing a first mesh;

b) providing a second mesh spaced apart from and substantially parallel to the first mesh;

c) directing at least one first warp thread through the first mesh; and

d) directing the at least one first warp thread between the first mesh and the second mesh at selected intervals to create a plurality of webs between the first mesh and the second mesh, thereby forming a honeycomb.

2. The method of claim 1 also comprising the steps of:

a) directing at least one second warp thread through the second mesh; and

b) directing the at least one second warp thread between the second mesh and the first mesh at selected intervals to form at least a portion of a plurality of webs between the first mesh and the second mesh.

3. The method of claim 1 also comprising the step of placing a slat on each of the webs.

4. The method of claim 3 wherein the slats are opaque.

5. The method of claim 3 wherein the slats are one of wood, metal, plastic, textile, or composite material.

6. The method of claim 1 wherein:

a) the first mesh is comprised of a set of substantially parallel first base threads and a set of substantially parallel first top threads;

b) the second mesh is comprised of a set of substantially parallel second base threads and a set of substantially parallel second top threads; and

c) a plane passing through any selected first top thread will intersect a plane passing through an opposite second top thread at a selected angle greater than 0° and

less than 90°

.

7. The method of claim 6 wherein the selected angle is 45°

.

8. The method of claim 1 also comprising the step of attaching the honeycomb to at least one of a headrail, a bottomrail, or a roller.

9. The method of claim 8 also comprising the step of routing lift cords through the honeycomb.

10. The method of claim 8 also comprising the step of routing lift cords adjacent the honeycomb and extending from the bottomrail into the headrail.

11. The method of claim 8 wherein one of a horizontal shade, a vertical shade or a roller shade are formed.

12. A honeycomb comprised of a front sheet, a back sheet and a plurality of webs therebetween wherein

the front sheet is comprised of a first mesh having at least one first warp thread woven therethrough;

the back sheet is comprised of a second mesh having at least one second warp thread woven therethrough; and

the webs are comprised of at least one of the first warp thread or the second warp thread.

13. The honeycomb of claim 12 also comprising a slat on each of the webs.

14. The honeycomb of claim 13 wherein the slats are opaque and both the front sheet and the back sheet are translucent.

15. The honeycomb of claim 13 wherein the slats are one of wood, metal, plastic, textile, or composite material.

16. The honeycomb of claim 12 also comprising at least one of a headrail, a bottomrail or a roller attached to the front sheet and the back sheet to form one of a horizontal shade, a vertical shade, a roller shade.

17. The honeycomb of claim 12 also comprising at least one lift cord routed through the honeycomb.

18. The honeycomb of claim 12 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 routed adjacent the honeycomb and extending from the bottomrail into the headrail.

19. The honeycomb of claim 12 wherein:

a) the first mesh is comprised of a set of substantially parallel first base threads and a set of substantially parallel first top threads;

b) the second mesh is comprised of a set of substantially parallel second base threads and a set of substantially parallel second top threads; and

c) a plane passing through any selected first top thread will intersect a plane passing through an opposite second top thread at a selected angle greater than 0° and

less than 90°

.

20. The method of claim 19 wherein the selected angle is 45°
