Dual fabric covering for architectural openings

摘要

A covering for an architectural opening with improved insulating properties in one embodiment includes face-to-face cellular insulative components defining a fabric with dual layers of cells with the fabric being retractably mounted in a headrail so as to either be rolled about a roller or gathered adjacent to the bottom of the headrail. A first component of the fabric includes a pair of spaced parallel sheets of material interconnected with horizontally-extending flexible vanes so as to define a plurality of horizontally-extending, vertically adjacent cells of generally rectangular cross-sectional configuration. A second component of the fabric is mounted on one sheet of the first component of the fabric so as to form a plurality of vertically adjacent drooping segments of fabric forming a roman-shade appearance. Single or multiple layers of the components can be used with or without the other type of component.

主权项

1. A covering for an architectural opening, comprising:
a headrail; a bottom rail operably associated with said headrail and extendable from and retractable to said headrail; and a fabric operably associated with said headrail and said bottom rail, said fabric including a first cellular component and a second cellular component,
said first cellular component including a pair of vertically-extending, parallel sheets interconnected at vertically-spaced locations by a plurality of horizontally-disposed vanes, each of said vanes including vertically-oriented end portions attached to said sheets, said first cellular component defining a plurality of cells between said sheets and adjacent vanes, andsaid second cellular component including a material attached to one of said sheets to form a plurality of droops of said material, each of said plurality of droops attached to said one of said sheets at a first location aligned with one of said vertically-oriented end portions of one of said vanes and at a second location aligned with one of said vertically-oriented end portions of another one of said vanes to define a plurality of vertically-adjacent cells horizontally disposed from said one of said sheets, wherein when the covering is in a retracted position, said sheets of said first cellular component overlap each other and substantially gather on a first side of said bottom rail, and said second cellular component substantially gathers on a second side of said bottom rail.
