Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 121 words
A reflecting device for the display of information which includes a substantially flat layer of highly reflecting material placed over a backing member and over which is laid a single flexible sheet of transparent or translucent synthetic plastics material having the information printed thereon, the flat layer, the backing member, and the sheet all being held together by a frame carrying a pane of substantially rigid transparent material having parallel, flat front and rear surfaces, said frame being constructed in such a manner that it can readily be opened for removal and replacement of the sheet, whereby a person's mirror image is viewable in the flat layer through the pane and sheet while simultaneously viewing the information printed on the sheet.
Claim 2
Dependent Claim 121 words
A reflecting device for the display of information which includes a substantially flat layer of highly reflecting material placed over a backing member and over which is laid a single flexible sheet of transparent or translucent synthetic plastics material having the information printed thereon, the flat layer, the backing member, and the sheet all being held together by a frame carrying a pane of substantially rigid transparent material having parallel, flat front and rear surfaces, said frame being constructed in such a manner that it can readily be opened for removal and replacement of the sheet, whereby a person's mirror image is viewable in the flat layer through the pane and sheet while simultaneously viewing the information printed on the sheet.
Claim 3
Dependent Claim 34 words
A reflecting device according to claim 1 in which the flat layer is formed by a film of highly-reflective synthetic plastics material, and the sheet is transparent and is smoothly laid over the film.
Claim 4
Dependent Claim 26 words
A device according to claim 2 in which the sheet is placed over the highly reflecting material and is secured around its edges by the frame.
Claim 5
Dependent Claim 17 words

Claim 6
Dependent Claim 14 words
A device according to claim 1, in which the sheet is of cellulose acetate.
Claim 7
Dependent Claim 20 words
A device according to claim 1 in which the sheet is printed on its surface which contacts the reflective material.
Claim 8
Dependent Claim 13 words
A device according to claim 1 in which the pane comprises plain glass.
Claim 9
Dependent Claim 38 words
A device according to claim 1 in which the frame is hinged to the backing member so that it can be opened to allow insertion of the sheet and closed to hold the sheet against the backing member.
Claim 10
Dependent Claim 21 words
A device according to claim 1 in which the visible portion of the sheet and the flat layer are both rectangular.
Claim 11
Dependent Claim 26 words

Claim 12
Dependent Claim 13 words
A device according to claim 8 in which the backing member is resilient.
Claim 13
Dependent Claim 136 words
A reflecting device for the display of information comprising a substantially flat layer of highly reflecting material placed over a rectangular backing member and over which is laid a single sheet of plastic material through which a person's mirror image is viewable in said flat layer, said sheet bearing an advertising legend thereon, the sheet, the flat layer, and the backing member being held together in that order by a frame carrying a pane of flat substantially rigid transparent material which frame is supported by means whereby it can be opened and closed to respectively move the pane away from or toward the flat layer for removal and replacement of the sheet, whereby a person's mirror image is viewable in the flat layer through the sheet and pane while simultaneously viewing the legend on the sheet.
Claim 14
Dependent Claim 136 words
A reflecting device for the display of information comprising a substantially flat layer of highly reflecting material placed over a rectangular backing member and over which is laid a single sheet of plastic material through which a person's mirror image is viewable in said flat layer, said sheet bearing an advertising legend thereon, the sheet, the flat layer, and the backing member being held together in that order by a frame carrying a pane of flat substantially rigid transparent material which frame is supported by means whereby it can be opened and closed to respectively move the pane away from or toward the flat layer for removal and replacement of the sheet, whereby a person's mirror image is viewable in the flat layer through the sheet and pane while simultaneously viewing the legend on the sheet.
Claim 15
Dependent Claim 13 words
A device according to claim 12 in which said sheet comprises cellulose acetate.
