COLLAPSIBLE CELLULAR SHADE ASSEMBLY AND METHOD FOR CONSTRUCTING SAME

摘要

An expandable and contractable cellular shade assembly (10) includes a plurality of closed D-shaped cell structures (12) aligned vertically one above another with juncture lines (16) defined between adjacent structures. Each closed cell structure (12) includes a front face (22) and a separate back face (26) that are attached to one another at top and bottom tabs (17). The front face (22) of one cell structure (12) is attached but non-continuous to the front face (22) of an adjacent cell structure (12). Accordingly the horizontal width of the shade assembly (10) is not limited by the width of the materials forming the individual cell structures (12). Upon collapse, the back face (26) folds toward the front (14) of the shade such that the back face (26) and the front face (22) are nested within one another, leading to a narrow depth profile for the collapsed shade.
