The present invention relates generally to window coverings and, more particularly, to so-called “Roman shades”, and still more particularly to Roman shades having lining panels.
Roman shades have long been used for both decorative and functional coverings on windows and other architectural openings. Roman shades made of many different materials have been used, including lightweight fabrics, heavier fabrics, horizontally slatted material of wood or faux-wood, woven fibrous materials and other natural and synthetic materials. When fabric materials are used, either a single ply heavy fabric or a lighter weight fabric with or without linings can be used to provide a high degree of privacy and light blocking. When the slatted or woven materials are used, gaps between the slats or woven materials can permit entrance of undesirable light streams, which may provide an undesirable appearance. Accordingly, it has been known to provide a fabric lining panel on the window side of wood, faux wood and other Roman shades having shade panels that are open or widely porous.
In a known construction, the lining panel is attached to the headrail and along the edges with a pattern of hand stitches. The shade requires vertical columns of cord rings attached to the back of the shade to guide the cords that are used to lift the shade. In a known construction, the rings are attached to the wood or faux wood panel and extended through slits in the lining panel. Alternatively, the cord rings are attached directly through the lining panel fabric. In either construction, the cord rings hold the lining panel in place but are exposed on the back of the shade, and the lift cords are extended along the outer surface of the lining material on the back of the shade. Disadvantages from this construction include having cords and rings that are visible on the back of the shade, particularly if the cords are not of the same color as the lining panel. Visible cords are undesirable. Exposed cords can present operational difficulties and safety concerns. Any slits or breach in the lining panel fabric can allow light leakage, and the slits can tend to fray from movement of the cords when the blind is operated. Further, when slitting the lining panel to accommodate the cord rings, or when attaching cord rings through the lining panel, it is difficult to get the slits and/or rings aligned properly, and it is easy to create puckers in the lining panel fabric that present an aesthetically undesirable appearance. Generally, the time required to assemble a blind of this type is longer than desirable, adding to manufacturing costs.
Attaching the lining over the cords, with the cord sandwiched between the lining and the primary shade material can provide a clean look on the street side of the shade. It is known to provide the lining with pleats to define spaced tabs on the inside of the lining panel fabric. The lift corridor then passes through the cord rings on the shade and through holes in the tabs on the inside of the lining. Alternatively, the lining panel can be provided as a functionally separate shade, requiring a dedicated lift system that operates independently of the main shade. Each of these constructions for concealing the lift cords is complex, adding to the difficulty and expense of manufacture and assembly.
A simpler construction, that can be assembled more easily, is desirable and advantageous.
A lined Roman shade construction that is easy to assemble, aesthetically pleasing and a functional improvement over known constructions for Roman shades with linings, while also overcoming disadvantages of exposed lift cords is provided.
In a form thereof, a Roman shade is provided with a headrail, shade material depending from the headrail and a lining panel substantially coextensive with the shade material. Cord rings are connected to the shade material and positioned between the shade material and the lining panel. The cord rings are arranged in vertical columns and horizontal rows. Lift cords depend from the headrail and extending through the cord rings in vertical columns. Discrete attachment points of the lining panel to the shade material substantially are aligned horizontally with horizontal rows of the cord rings.
In another a form thereof, a method for assembling a Roman shade is provided with steps of securing cord rings to shade material in vertical columns and horizontal rows; threading lift cords through individual cord rings in the vertical columns of cord rings; placing a lining panel over the cord rings and lift cords and against the shade material; and attaching the lining panel to the shade material at discrete connections aligned with horizontal rows of cord rings.
In a further aspect of a form thereof, a Roman shade is provided with shade material, a lining panel and cord rings connected to the lining panel. The cord rings are arranged in a plurality of horizontal rows. Discrete connections of the lining panel to the shade material are aligned with the horizontal rows of the cord rings.
Attachment of the lining panel to the shade material in at least some forms thereof provides an aesthetically appealing, smoothly and consistently operating shade with concealed and protected lift cords and cord rings.
Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings in which like numerals are used to designate like features.
Before the embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use herein of “including”, “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof, as well as additional items and equivalents thereof.
Referring now more particularly to the drawings,
Lift cords 18, 20 pass through columns of vertically spaced cord rings 22 so that cords 18, 20 can slide through the rings 22 as shade material 14 is bunched when lifting Roman shade 10, or loosened and extended when lowering Roman shade 10. Lift cords 18, 20 and cord rings 22 are disposed between shade material 14 and a lining panel 24. Accordingly, to facilitate a better understanding of the construction of Roman shade 10, in
For functional and/or aesthetic purposes, including to providing increased privacy and light blocking, lining panel 24 is provided as a liner or backing to shade material 14. It is desirable and aesthetically preferable that lining panel 24 bunches substantially consistently with the bunching of shade material 14 when lift cords 18, 20 are raised, and that lining panel 24 remains substantially aligned with shade material 14 when lift cords 18, 20 are extended to lower shade material 14. Lining panel 24 is attached to headrail 12 and against shade material 14 with concealed fasteners such as staples or nails 26 (
Lining panel 24 is draped down the back of Roman shade 10, covering lift cords 18, 20 and cord rings 22 to both conceal and protect lift cords 18, 20 and cord rings 22. Lining panel 24 is fastened or attached to shade material 14 at discrete, spaced locations along the extent thereof. In the exemplary embodiment, lining panel 24 is stitched to shade material 14 in vertical columns of stitches 30, 32 (
For wide shades, additional vertical columns of discrete attachments such as stitches 34 can be provided between the vertical columns of cord rings 22, with the individual stitches 34 being aligned horizontally with the cord rings 22 of a horizontal row and the individual stitches 30, 32 in outboard columns of stitches 30, 32. The pattern of horizontally aligned stitches 30, 32, 34 aligned with pairs of cord rings 22 controls how the lining panel piles or bunches as the shade is raised. Stitches 34 can be provided in some or in all of the horizontal rows of cord rings 22.
A horizontal row of stitches 36 also can be provided to attach the bottom edge of lining panel 24 to the bottom edge of shade of material 14.
Stitches 30, 32, 34 secure lining panel 24 to shade material 14. Since individual stitches 30, 32, 34 also are aligned horizontally with horizontal rows of cord rings 22, lining panel 24 folds and bunches in the same pattern as and in close relationship to shade material 14, as shade material 14 bunches when lift cords 18, 20 are raised.
The stitches 30, 32, 34 described herein can be applied by hand or by automated machinery. Alternatively, other fastening techniques can be used to create discrete, spaced connections between shade material 14 and lining panel 24, with the discrete, spaced connections aligned as for the stitches 30, 32, 34 described above. For example, garment tag fasteners, staples, glue, heat-fusible tape or other attachment methods can be used to establish the connections between shade material 14 and lining panel 24.
While shown and described herein for a Roman shade having slats of wood or other natural or synthetic materials, the construction and method described herein can be used for fabric Roman shades having fabric shade panels and fabric lining panels
