Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
219 words
A sign structure comprising: a plurality of elongated sign frame elements each joined at its ends to an adjacent sign frame element to define a sign frame having a closed center portion; a facing material having an edge corresponding to each edge of said sign frame and having a shape and size sufficient to cover one face of said sign frame; a facing material gripping means associated with each edge of said facing material for gripping said facing material; connection means for connecting each of said facing material gripping means to a corresponding sign frame element; and wherein each of said sign frame elements includes an elongated, generally flat base having a pair of generally parallel longitudinal edges and being disposed at right angles with respect to said facing material, a first flange portion integrally formed with one of the longitudinal edges of said base and extending inwardly toward said center portion of said sign structure at right angles to and inwardly of the innermost portion of said base and a second flange portion integrally formed with the other of the longitudinal edges of said base and extending outwardly from said center portion of said sign structure in a direction opposite said first flange portion and at right angles to and outwardly of the outermost portion of said base.
Claim 2
Dependent Claim
219 words
A sign structure comprising: a plurality of elongated sign frame elements each joined at its ends to an adjacent sign frame element to define a sign frame having a closed center portion; a facing material having an edge corresponding to each edge of said sign frame and having a shape and size sufficient to cover one face of said sign frame; a facing material gripping means associated with each edge of said facing material for gripping said facing material; connection means for connecting each of said facing material gripping means to a corresponding sign frame element; and wherein each of said sign frame elements includes an elongated, generally flat base having a pair of generally parallel longitudinal edges and being disposed at right angles with respect to said facing material, a first flange portion integrally formed with one of the longitudinal edges of said base and extending inwardly toward said center portion of said sign structure at right angles to and inwardly of the innermost portion of said base and a second flange portion integrally formed with the other of the longitudinal edges of said base and extending outwardly from said center portion of said sign structure in a direction opposite said first flange portion and at right angles to and outwardly of the outermost portion of said base.
Claim 3
Dependent Claim
27 words
The sign structure of claim 1 wherein each of said first and second flange portions includes first and second leg members adjacent and parallel to one another.
Claim 4
Dependent Claim
40 words
The sign structure of claim 2 wherein said first leg member of each of said first and second flange portions is integrally connected with said base and said second leg member is integrally connected with its corresponding first leg member.
Claim 5
Dependent Claim
23 words
The sign structure of claim 1 wherein said connection means includes facing material tensioning means on at least two adjacent sign frame elements.
Claim 6
Dependent Claim
27 words
The sign structure of claim 4 wherein said facing material tensioning means includes a plurality of ratchet members connected to the base of said sign frame elements.
Claim 7
Dependent Claim
77 words
The sign structure of claim 1 wherein said facing material gripping means associated with at least one edge of said facing material includes an elongated tubular element extending substantially the entire length of said one edge, an elongated slot extending longitudinally along said tubular member and a generally cylindrical tube of smaller diameter than the internal dimension of said tubular member, said tube adapted for insertion within said tubular member with said facing material looped around it.
Claim 8
Dependent Claim
55 words
The sign structure of claim 1 including an elongated shroud element associated with each of said sign frame elements, each of said shroud elements including a first longitudinal edge pivotally secured to said second leg of its associated sign frame element and a second longitudinal edge extending over an edge portion of said facing material.
Claim 9
Dependent Claim
118 words
The sign structure of claim 1 wherein said facing material gripping means associated with at least one edge of said facing material includes an elongated bar having an elongated cross-sectional configuration, said one edge of said facing material extending around said bar and secured to a portion of said facing material to form a loop, and an elongated retaining bracket having a first leg secured to one of said sign frame elements, a second leg integrally formed with and extending from said first leg at right angles and a third leg integrally formed with said second leg and extending in spaced relationship and parallel to said one sign frame member to form a pocket to receive said bar.
Claim 10
Dependent Claim
26 words
The sign structure of claim 7 including a plurality of shroud supporting posts mounted on and extending outwardly at spaced intervals along each of said bases.
Claim 11
Dependent Claim
18 words
The sign structure of claim 9 including means for connecting said shroud elements to said shroud supporting posts.
Claim 12
