Abstract
Abstract Illuminated advertising device with high-intensity flickering light effect, comprising in a casing three replaceable lighttransmitting sheets of which the outermost carries the advertisement, the next following sheet is an ornamental sheet carrying regular projections, and the third or innermost sheet provides the flickering effect on account of a planar movement imparted thereto and having irregular projections on its side facing those of the ornamental sheet. The flicker sheet is specially made from approx. 3 millimeter thick acrylic resin. Mirrors may be provided so as to add reflected light to the direct light of incandescent lamps. A color foil may optionally be inserted between two adjoining sheets, such as the advertising and the ornamental sheets of the device. A small motor with an eccentric arrangement actuates the flicker sheet.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
An advertising device with high-intensity flickering light effect, comprising, in combination, a casing, illuminating means in said casing for emitting a steady light, at least three replaceable, at least partly light-transmitting sheets mounted in said casing, the outermost sheet being adapted to carry an advertisement and the like, the next inwardly following, intermediate sheet being an ornamental sheet provided with substantially regular protuberances on at least one face, and the innermost sheet being movable and provided with substantially irregular protuberances on at least one face, said protuberances on the innermost and the intermediate sheets facing each other, and those of the former acting as minute concentrating lenses, and means for reciprocating said innermost sheet, thereby producing the flickering effect in the light passing through said intermediate and said outermost sheets.
Claim 2
Dependent Claim
130 words
An advertising device with high-intensity flickering light effect, comprising, in combination, a casing, illuminating means in said casing for emitting a steady light, at least three replaceable, at least partly light-transmitting sheets mounted in said casing, the outermost sheet being adapted to carry an advertisement and the like, the next inwardly following, intermediate sheet being an ornamental sheet provided with substantially regular protuberances on at least one face, and the innermost sheet being movable and provided with substantially irregular protuberances on at least one face, said protuberances on the innermost and the intermediate sheets facing each other, and those of the former acting as minute concentrating lenses, and means for reciprocating said innermost sheet, thereby producing the flickering effect in the light passing through said intermediate and said outermost sheets.
Claim 3
Dependent Claim
24 words
The advertising device as defined in claim 1, wherein said innermost sheet is made of an acrylic thermoplastic material of approximately 3 millimeters thickness.
Claim 4
Dependent Claim
27 words
The advertising device as defined in claim 1, wherein said innermost sheet has at least on its front surface random honeycomb-shaped protuberances of different heights and peripheries.
Claim 5
Dependent Claim
84 words
The advertising device as defined in claim 3, further comprising an additional replaceable, at least partly light-transmitting sheet interposed between two adjoining ones of said light-transmitting sheets, and means associated with said casing for removably and adjustably supporting at least one of said outermost, said intermediate and said additional light-transmitting sheets, said supporting means including at least one groove for said at least one of the light-transmitting sheets, and at least one access opening for selectively inserting and removing said at least one sheet.
Claim 6
Dependent Claim
96 words
The advertising device as defined in claim 1, further comprising means in the direct path of the light rays to break up and concentrate the light emitted by said illuminating means and passing through said light-transmitting sheets, using both direct and reflected rays, to produce continuous changes in the propagation direction of said rays, and wherein said innermost sheet allows about 95 percent light to pass, with the angles of incidence of the light falling on said innermost sheet being different from the angles in which said rays leave the front surface of said innermost sheet.
Claim 7
Dependent Claim
35 words
The advertising device as defined in claim 1, wherein said reciprocating means includes a mechanism for imparting a repetitive planar movement to said innermost sheet such that any point thereon follows a substantially circular path.
Claim 8
Dependent Claim
40 words
The advertising device as defined in claim 6, wherein said mechanism inclUdes drive means, eccentric means operated thereby, and operatively associated with said innermost sheet to move the same in a plane substantially parallel with that of said intermediate sheet.
Claim 9
Dependent Claim
37 words
The advertising device as defined in claim 6, wherein the diameter of said circular path is of the order of 11 milliemeters while the rate of repetition is of the order of approximately 40 movements per minute.
Claim 10
Dependent Claim
30 words
The advertising device as defined in claim 1, further comrising an additional replaceable, at least partly light-transmitting sheet interposed between two adjoining ones of said at least three light-transmitting sheets.
Claim 11
Dependent Claim
23 words
The advertising device as defined in claim 9, wherein said additional sheet is made of an acetate material of approximately 0.1 millimeter thickness.
Claim 12
Dependent Claim
33 words
The advertising device as defined in claim 9, further comprising means associated with said casing for removably and adjustably supporting at least one of said outermost, said intermediate and said additional light-transmitting sheets.
