Abstract
Abstract A display device consists of a plate-like sheet of rigid transparent material having a pair of spaced opposite parallel edges. The sheet is bent in the area of each of the edges along lines parallel to and spaced from the edges to form a pair of lips. Each of the lips extends at a predetermined angle with the sheet in the area of a corresponding one of the edges. Each angle opens toward the other. Adhesive is provided on corresponding surfaces of the lips.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A display device, comprising a plate-like sheet of substantially rigid transparent material having a pair of spaced opposite substantially parallel edges and bent in the area of each of said edges along lines substantially parallel to and spaced from said edges to form a pair of lips each extending at a predetermined angle with the sheet of material in the area of a corresponding one of said edges, each angle opening toward the other, each of the lips being bent on itself along a line parallel to and intermediate the edge and the line at the juncture of the corresponding one of the lips and the remainder of the sheet to form a pair of trough-like configurations opposite each other and opening toward each other; and adhesive means on corresponding surfaces of the lips.
Claim 2
Dependent Claim
134 words
A display device, comprising a plate-like sheet of substantially rigid transparent material having a pair of spaced opposite substantially parallel edges and bent in the area of each of said edges along lines substantially parallel to and spaced from said edges to form a pair of lips each extending at a predetermined angle with the sheet of material in the area of a corresponding one of said edges, each angle opening toward the other, each of the lips being bent on itself along a line parallel to and intermediate the edge and the line at the juncture of the corresponding one of the lips and the remainder of the sheet to form a pair of trough-like configurations opposite each other and opening toward each other; and adhesive means on corresponding surfaces of the lips.
Claim 3
Dependent Claim
29 words
A display device as claimed in claim 1, wherein the adhesive means is on the surface of the lip of each of the trough-like configurations farthest from the sheet.
Claim 4
Dependent Claim
33 words
A display device as claimed in claim 1, wherein the adhesive means is on the surface of each lip of each of the trough-like configurations farthest from each other and from the sheet.
Claim 5
Dependent Claim
40 words
A display device as claimed in claim 1, wherein the lips of each of the trough-like configurations are at an obtuse angle with each other, one of the lips of each of the trough-like configurations being parallel with the sheet.
Claim 6
Dependent Claim
160 words
A display device, comprising a plate-like sheet of substantially rigid transparent material having a pair of spaced opposite substantially parallel edges and bent in the area of each of said edges along lines substantially parallel to and spaced from said edges to form a pair of lips each extending at a predetermined angle with the sheet of material in the area of a corresponding one of said edges, each angle opening toward the other; adhesive means on corresponding surfaces of the lips; and a pad of material removably positioned against the sheet by the lips thereby maintaining a picture, and the like, in position between the pad and the sheet in a manner whereby the picture, and the like, is viewable through the surface of the sheet farthest from the lips when the device is affixed to a first surface via one of the lips and to a second surface meeting the first surface via the other of the lips.
Claim 7
Dependent Claim
