Abstract
Abstract A support frame for solid screen or flexible sheet panel material comprising an originally elongated strip which includes a hem edge having a substantially hemispherical button tip configuration defined by a fold substantially located along the longitudinal axis of the strip. A plurality of pairs of slots having a T-shaped configuration are formed in the strip such that the strip may be turned at these points and thereby define corners of a polygon engaging the material about its periphery and providing support therefor. Hooks, serving as material connecting means; hinges, used to pivotally attach the frame; and clips used for closure means are all integrally formed in the strip and protrude from predetermined sides of the surface thereof in order to secure the material to the frame or mount the frame itself respectively.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
170 words
A frame designed to support flexible material by engagement with a substantial portion of the periphery thereof, said frame comprising: a strip folded substantially along its longitudinal axis to define a hem edge, two side walls each located on opposite sides of said hem edge, corner forming means formed in said strip in predtermined spaced relation to one another such that portions of said strip on either side of said corner forming means are folded in angular relation to one another, material connecting means integrally formed in each of said side walls whereby said side walls are positioned in substantially parallel relation to one another and on both sides of said material; hinge means integrally formed in said side walls in spaced relation to one another, and extending from the surface of said respective side walls outwardly on the exterior of said folded strip, said material connecting means positioned on said side walls to lockingly engage the material and said frame comprising a polygon configuration when said corners are formed.
Claim 2
Dependent Claim
170 words
A frame designed to support flexible material by engagement with a substantial portion of the periphery thereof, said frame comprising: a strip folded substantially along its longitudinal axis to define a hem edge, two side walls each located on opposite sides of said hem edge, corner forming means formed in said strip in predtermined spaced relation to one another such that portions of said strip on either side of said corner forming means are folded in angular relation to one another, material connecting means integrally formed in each of said side walls whereby said side walls are positioned in substantially parallel relation to one another and on both sides of said material; hinge means integrally formed in said side walls in spaced relation to one another, and extending from the surface of said respective side walls outwardly on the exterior of said folded strip, said material connecting means positioned on said side walls to lockingly engage the material and said frame comprising a polygon configuration when said corners are formed.
Claim 3
Dependent Claim
73 words
A frame as in claim 15 wherein said corner forming means comprising a pair of T-slots, each slot having a substantially T-shaped configuration and disposed such that the base of each is arranged in substantially parallel relation on opposite sides of said hem edge, flanges arranged adjacent to each of said slots so as to be positioned in overlapping relation when portions of said strip are folded in angular relation to one another.
Claim 4
Dependent Claim
35 words
A frame as in claim 3 including at least one locking aperture formed in each of said flanges, said apertures in adjacent flanges positioned in overlapping relation when said flanges are positioned in overlapping relation.
Claim 5
Dependent Claim
31 words
A frame as in claim 2 wherein each of said slots has one extremity spaced from said hem edge and the other estremity extending to said oppositely disposed free side edge.
Claim 6
Dependent Claim
25 words
A frame as in claim 1 wherein said hinge means are positioned in spaced, non-engaging relation to both said hem edge and said side edge.
Claim 7
Dependent Claim
59 words
A frame as in claim 1 wherein said frame further comprises bracket means integrally formed in said side walls in spaced relation to one another, and extending from the surface of said respective side wall outwardly on the exterior of said folded strip, whereby closure means may be attached thereto so as to maintain said frame in locked position.
Claim 8
Dependent Claim
42 words
A frame as in claim 1 wherein said hem edge comprises a substantially hemispherical configuration extending along its length, said hem edge dimensioned to define a button head at each corner determined by the folded angularly oriented strip portion defining said corners.
Claim 9
Dependent Claim
37 words
A frame as in claim 1 wherein said parallel arranged side walls each further comprise a longitudinal crease extending substantially parallel to said hem edge, such that each of said side walls include a substantially L-shape configuration.
Claim 10
Dependent Claim
45 words
A frame as in claim 15 in combination with a material holding means , said holding means comprising a plurality of longitudinally extending arms arranged in co-planar, angular relation to one another, whereby the length of each arm may be extended independently of The others.
Claim 11
Dependent Claim
33 words
A frame and holding assembly combination as in claim 17 wherein each of said arms comprises a plurality of portions telescopically arranged relative to one another, whereby extension of said arms are permitted.
Claim 12
Dependent Claim
17 words
A frame and holding assembly combination as in claim 17 wherein said material holding means is magnetized.
Claim 13
Dependent Claim
75 words
A frame as in claim 1 wherein said material connecting means comprises a plurality of hook members disposed on opposite sides of said hem edge and in spaced relation to each other in both side walls, said hooks extending from the surface of each of said side walls inwardly toward the interior of said folded strip, whereby positioning of said side walls in substantially parallel position locates said hooks in locking engagement with said material.
Claim 14
Dependent Claim
24 words
A frame as in claim 12 wherein said hooks are positioned in spaced, non-engaging relation to both said hem edge and said side edge.
