Embodiment Construction

[0019]The term “roman shade” as used herein refers to a window treatment consisting of a flat panel made of a woven or non-woven fabric, or other material such as woven wood, plastic, etc., which is selectively lifted by a user (either by manual or motorized means) in a manner that causes horizontal sections of the panel to generate successive folds or pleats.

[0020]A typical prior art roman shade 200 is shown somewhat diagrammatically in FIG. 1 and it consists of a panel 212 made of a fabric or other decorative material that is relatively supple, as describe above. At the bottom of the panel 212, there is provided a hembar 213 or other elongated member extending along the width of the panel 212 to maintain the panel 212 in a stretched and relatively planar configuration when opened, and to also assist in the operation of the shade. A headrail (not shown) is provided on the top for supporting the panel 212 after mounting.

[0021]As is conventional with such window coverings, the panel ...

Abstract

A roman shade includes a panel, a plurality of clips attached to the panel, the clips forming elongated, narrow guides on the back side of the panel and a plurality of tapes. The panel is mounted on a headrail that also includes a rotating tube. Each tape is attached to the bottom of the panel at one end and to the tube at the other end and passes through the narrow guides to cause the panel to form successive folds or pleats as the bottom of the panel is raised by the tapes by the rotation of the tube.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application Ser. No. 61 / 302,898 filed Feb. 9, 2010 entitled Shade Lift System and incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]A. Field of Invention[0003]This invention pertains to a window covering generally referred to as a roman shade in which instead of relatively thin cords, tapes are used for lifting portions of a panel.[0004]B. Description of the Prior Art[0005]Typically, roman shades include a panel, a header from which the panel is supported and control cords. The cords have one end tied to a rod disposed at the bottom of the panel (generally known as the hembar), and pass through loops attached at regularly spaced intervals on the back side of the panels. The panels and cords cooperate so that as the cords are pulled, they lift the hembar and cause portions of the panel to overlap creating a series of folds or pleats oriented toward the front of the pa...
