Cellular shade assembly and method for constructing same

摘要

An expandable and contractable shade assembly includes a plurality of closed cell structures aligned vertically one above another with juncture lines defined between adjacent structures. Each closed cell structure includes a front face and a separate back face. The front face and the back face are offset from one another in relation to a vertical axis. In one embodiment, for instance, the front face of a higher cell is connected to both the front face and back face of a lower cell, while the back face of the higher cell is only connected to the back face of the lower cell. In an alternative embodiment, the front face of a higher cell is only connected to the front face of a lower cell, while the back face of the higher cell is connected to both the front face and the back face of the lower cell. The above configuration can increase strength and dimensional stability of the interconnected cells.

1. A cellular shade comprising:
a plurality of sequential and interconnected closed cell structures extending in a longitudinal direction, the cell structures having a collapsed position when the shade is retracted and having an open position when the shade is extended, the plurality of closed cell structures including a higher cell structure and an adjacent lower cell structure, wherein the higher and lower cell structures each include a front face and a separate back face, each front face including a first segment separated from a second segment by a first fold line, and each back face including a corresponding first segment separated from a corresponding second segment by a second fold line, wherein the first segments of the front faces each have a. length less than the length of the second segments of the front faces and wherein the first segments of the back faces each have a length greater than the length of the second segments of the back faces, and wherein the front face of the higher cell structure is attached to the front face of the lower cell structure and the back face of the higher cell structure is attached to the back face of the lower cell structure; wherein the second segment of the front face of the higher cell structure overlaps with both the front face and the back face of the lower cell structure, and wherein the second segment of the back face of the higher cell structure overlaps with only the back face of the lower cell structure; and a lift system configured for vertically drawing said cell structures from an expanded configuration into a contracted configuration.
