A cell in cell covering for architectural openings including inner and outer concentric cells

摘要

A dual cell fabric (98), also referred to as a cell-in-cell fabric, comprising a plurality of concentric dual cells (96) that are connected to an adjacent cell along a top and bottom side. Each dual cell of the fabric is made of a flexible material such as a fabric material that is transversely collapsible but retains its configuration along its length when suspended between the head rail (92) and the bottom rail (94). The dual cells consist of an outer cell (100) having pleated front and edges (100a) and (100b) respectively and a smaller concentric cell (102) having corresponding front and rear pleated edges (102a) and (102b), respectively, spaced inwardly from the front and rear edge of the outer cell. Both the inner and outer cells are symmetric about a horizontal plane intersecting a central longitudinal axis of the cells as well as about a similar vertical plane.
