Abstract
Abstract A Roman-type shade and method of fabrication. The fabric of the shade is formed into a series of horizontally extending, vertically spaced parallel folds which carry flexible battens adapted to rigidly hold the folds when the shade is hung and which permit cleaning of the shade without removal of the battens. In one embodiment the battens are secured within the folds by a line of stitching which extends through both the fabric and battens and with rearwardly extending marginal portions of the battens formed with openings and eyelets adapted to receive pull-cords arranged in a manner to raise and lower the shade. In another embodiment a line of stitching in the folds forms pockets for receiving the battens and with openings formed in certain battens for seating grommets which both receive the pull-cords and anchor the battens within the pockets. In the method, batten locations are marked on the fabric with portions of the fabric along the length of each mark secured to one flat side of individual battens by adhesive means. In adjacent portion of the fabric is then folded over and secured in overlying relationship with the opposite side of the batten by adhesive means. Lines of stitching are then formed to extend through the fabric and into the battens. Openings are formed in the battens and adjacent fold portions with eyelets seated in the openings to receive the pull-cords.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
126 words
In a shade device, the combination comprising at least one layer of fabric, a plurality of horizontally extending, vertically spaced U-shaped folds formed in said fabric layer, the folds having facing planar sides, a plurality of horizontally disposed elongate flexible battens, each batten having an initial planar configuration and being formed of an elastomeric material providing substantial flexing under stress and further providing plastic memory affording resilient return to said initial planar configuration upon removal of said stress, each of said battens being carried between the sides of individuals ones of said folds and extending the substantial length thereof, means fixedly securing each of the battens within the fold associated therewith, and means to vertically raise and lower the shade progressively from the lowermost portion thereof.
Claim 2
Dependent Claim
126 words
In a shade device, the combination comprising at least one layer of fabric, a plurality of horizontally extending, vertically spaced U-shaped folds formed in said fabric layer, the folds having facing planar sides, a plurality of horizontally disposed elongate flexible battens, each batten having an initial planar configuration and being formed of an elastomeric material providing substantial flexing under stress and further providing plastic memory affording resilient return to said initial planar configuration upon removal of said stress, each of said battens being carried between the sides of individuals ones of said folds and extending the substantial length thereof, means fixedly securing each of the battens within the fold associated therewith, and means to vertically raise and lower the shade progressively from the lowermost portion thereof.
Claim 3
Dependent Claim
39 words
A shade as in claim 1 wherein the means securing the battens within the folds comprises adhesive means disposed between the outer surfaces of said battens and the confronting surfaces of the portions of the layer forming said folds.
Claim 4
Dependent Claim
41 words
A shade as in claim 1 wherein said means securing the battens within respective folds includes at least one line of stitching extending along the length of said folds, said stitching securing together opposing portions of the layer forming said folds.
Claim 5
Dependent Claim
22 words
A shade as in claim 3 wherein said stitching extends through the opposed layer portions and is secured into the adjacent batten.
Claim 6
Dependent Claim
97 words
A shade as in claim 4 in which at least certain ones of said battens are formed with marginal portions which extend rearwardly of said folds, and said means to raise and lower the shade includes pull-cord means and a plurality of openings formed in the marginal portions of said battens, said openings being arranged in two or more rows of vertically aligned openings with said pull-cord means extending vertically through said aligned openings, and together with means for restraining the lowermost portions of said pull-cord means for vertical movement with a lower portion of the shade.
Claim 7
Dependent Claim
40 words
A shade as in claim 3 in which said means securing the battens within the folds further includes adhesive means disposed between the outer surfaces of the battens and the confronting surfaces of portions of the layer forming said folds.
Claim 8
Dependent Claim
26 words
A shade as in claim 1 in which at least certain Ones of said battens are formed with marginal portions which extend rearwardly of the folds.
Claim 9
Dependent Claim
48 words
A shade as in claim 1 in which said battens are formed of a synthetic polymer material having a thickness in the range between substantially 15 and 30 mil providing rigidity for holding said folds in substantially horizontal planar configuration and parallel alignment when the shade is hung.
Claim 10
Dependent Claim
32 words
A shade as in claim 3 in which said stitching secures together opposed portions of said folds into horizontally extending pockets, and said battens are disposed within individual one of said pockets.
Claim 11
Dependent Claim
73 words
A shade as in claim 9 in which said means securing the battens within the folds includes a plurality of openings formed through at least certain ones of said pockets and the battens associated therewith and grommet means disposed in said openings for securing together the portions of the fold and batten surrounding respective openings, and the means to raise and lower the shade includes pull-cord means extending vertically through the grommet means.
Claim 12
Dependent Claim
37 words
A shade as in claim 9 in which the means securing the battens within the folds includes stitch means extending through the folds at opposed ends of said pockets for restraining respective battens therein from longitudinal displacement.
Claim 13
Dependent Claim
60 words
A shade as in claim 1 which includes means forming a horizontally elongate hem pocket at the lower margin of said layer, weight means disposed in said pocket, and means forming a flap at an end of said hem pocket including means to releasably open and close said flap for inserting and removing said weight into and from said pocket.
Claim 14
Dependent Claim
66 words
A shade as in claim 12 for quick release from and attachment to a support fixture, and including means forming opposed strips of interengageable, selectively releasable fastener means, one of said strips being secured to said fixture and the other of said strips being secured to the upper margin of said shade whereby said strips when pressed into confronting relationship attach the shade to the fixture.
