Cellular shade having at least two cellular columns

摘要

An expandable and contractable shade assembly includes at least a first column of cell structures aligned vertically one above another and a second column of cell structures also aligned vertically one above the other. The second column of cell structures can be positioned offset and nested with the first cell structures such that each second cell structure may be positioned in between two adjacent of the first cell structures. One or more lift cords may be encased or contained within the first cell structures. The first cell structures not only have lift cords but also provide the product with added integrity.

主权项

1. A process for producing a cellular shade comprising:
forming a plurality of first cell structures from a first material that are disposed longitudinally along a width dimension and are aligned vertically one above another, each of the first cell structures including a first side and a second side extending between an upper first junction line and a lower first junction line, each of the first cell structures being coupled to adjacent first cell structures at the upper and lower first junction lines, and forming a plurality of second cell structures also disposed longitudinally along the width dimension, the second cell structures being formed offset from the first cell structures such that each second cell structure is positioned in between two adjacent first cell structures, the second cell structures including a first side and a second side extending between an upper second junction line and a lower second junction line, each of the second cell structures being coupled to adjacent second cell structures at the upper and lower second junction lines, the first side of the first cell structures forming the second side of the second cell structures, the first side of the second cell structures being made from a second material, the first cell structures including crease lines that allow the first cell structures to collapse into a closed position, wherein the second side of each second cell structure extending between the upper and lower second junction lines is formed entirely of the first material, wherein the second side of each second cell structure extending between the upper and lower second junction lines is formed entirely of the first material of two adjacent first cell structures.
