Abstract
Abstract A sign which includes a sign cabinet having a rigid frame on which a flexible vinyl sign face is stretched. The sign face has hems on its top and bottom edges. Rigid rods are inserted in the hems, and tension springs are extended through notches in the hems and hooked to the rods. The other ends of the springs are hooked on lips projecting from extrusions which extend along the top and bottom of the face frame. The springs hold the sign face taut on the sign cabinet frame. A special hinged end section is pivoted on the frame to permit the sign face to be placed under the proper lateral tension as a result of the lever action resulting from swinging the hinged section inwardly and then bolting it in place on the sign cabinet frame.

Claim 3
Dependent Claim
21 words
Apparatus as set forth in claim 1, wherein said hinge axis is spaced from the plane defined by said facing sheet.
Claim 4
Dependent Claim
75 words
Apparatus as set forth in claim 2, wherein said top and bottom members are located partially on said hinged frame section and partially on the remainder of said frame and including an angled joint between the part of each said top and bottom member on said hinged frame section and said part of each said top and bottom member on said remainder of said frame when the hinged frame section is in said first position.
Claim 5
Dependent Claim
211 words
Display apparatus comprising: a sign cabinet having a side which includes a frame presenting opposite first and second end portions; a flexible sign facing sheet having opposite first and second ends and a length to extend in a taut condition between said first and second end portions of said frame; means for attaching said first end of said facing sheet with said first end portion of said frame; a hinged frame section having a substantially vertical end member thereon; means for mounting said hinged frame section on said second end portion of said frame for pivotal movement about a substantially vertical hinge axis between a first position wherein said frame section serves as part of said frame and a second position wherein said frame section is pivotally displaced from said first position thereof; means for connecting said second end of said facing sheet to said end member while said frame section is in said second position and while said facing sheet is in a slack condition such that said facing sheet is drawn to a taut condition when said frame section is subsequently moved to said first position; and means for securing said hinged frame section in said first position thereof to secure said sign facing sheet in a taut condition.
Claim 6
Dependent Claim
211 words
Display apparatus comprising: a sign cabinet having a side which includes a frame presenting opposite first and second end portions; a flexible sign facing sheet having opposite first and second ends and a length to extend in a taut condition between said first and second end portions of said frame; means for attaching said first end of said facing sheet with said first end portion of said frame; a hinged frame section having a substantially vertical end member thereon; means for mounting said hinged frame section on said second end portion of said frame for pivotal movement about a substantially vertical hinge axis between a first position wherein said frame section serves as part of said frame and a second position wherein said frame section is pivotally displaced from said first position thereof; means for connecting said second end of said facing sheet to said end member while said frame section is in said second position and while said facing sheet is in a slack condition such that said facing sheet is drawn to a taut condition when said frame section is subsequently moved to said first position; and means for securing said hinged frame section in said first position thereof to secure said sign facing sheet in a taut condition.
Claim 7
Dependent Claim

Claim 11
Independent Claim
216 words
A method of installing a flexible sign facing sheet on a sign cabinet having a side which includes a frame presenting top and bottom members, opposite first and second end portions and a hinged frame section on the second end portion mounted to pivot thereon about a substantially vertical hinge axis, said method comprising the steps of: attaching one end of the facing sheet with the first end of the frame; the facing sheet between the top and bottom members of the frame; applying tension to the facing sheet in a manner to maintain the facing sheet tautly stretched between the top and bottom members of the frame; locating the hinged frame section in a pivotal position in which the facing sheet can be attached to the hinged frame section with the facing sheet providing lateral slack therein; attaching the facing sheet to the hinged frame section with the facing sheet having lateral slack therein; pivoting the hinged frame section about said hinge axis to a position wherein the hinged frame section serves as part of said frame and the facing sheet is drawn to a laterally taut condition; and securing said hinged frame section in the position wherein it serves as part of said frame to secure the facing sheet in a laterally taut condition.
Claim 12
Independent Claim
