发明名称 Expandable and contractable window covering
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. A lift system is configured for vertically drawing the closed cell structures from the fully expanded configuration into a fully contracted configuration, and includes a plurality of lift cords that are attached to back faces of the closed cell structures and lie along a vertical line of action rearward of the closed cell structures. In the fully contracted configuration of the shade assembly, the closed cell structures collapse into a flat profile and hang from the lift cords in a vertical and adjacently disposed orientation whereby upper edges of the collapsed closed cell structures are adjacent and oriented in an upward vertical direction, and bottom edges of the collapsed closed cell structures are adjacent and oriented in a downward vertical direction.
