Abstract
Abstract An advertising device is provided which includes a base and a display piece. The base has a display piece supporting surface and a magnet concealed beneath the surface. The display piece, which is of a size and weight to permit easy handling and carries advertising indicia, has a lamp, an electric battery and a reed switch, all connected in series with one another, encapsulated within the piece. The outer surface of the piece is smooth and uninterrupted and at least the battery and reed switch are concealed from view. The reed switch is positioned wholly within the display piece and physically isolated from the base surface when the piece is resting on the surface, but exposed to a magnetic field of the magnet in at least one position of the piece on the base surface, to change the position of the reed switch contact reeds relative to one another, either to close the circuit through the lamp to light the lamp, or to open the circuit to extinguish the lamp. Preferably, transformer and rectifying means by which the battery can be recharged are also encapsulated within the piece.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
An advertising device comprising a base and a manipulable display piece, said base having a clearly delineated supporting surface and a magnet concealed beneath said surface, said magnet having a pole eccentrically positioned with respect to the center of said delineated supporting surface, and said display piece having a lamp, an electric battery and a reed switch all connected in series with one another and all totally encapsulated within a solid plastic matrix, the outer surface of which is uninterrupted, said reed switch having an envelope and contact reeds within said envelope and movable with respect to one another in response to the presence of a magnetic field at said magnet pole, said reed switch being positioned within said piece to be physically isolated from said base surface when said piece is resting on said surface but to be exposed to said magnetic field for changing the position of the reed switch contact reeds relative to one another in at least one position of the piece on said base, advertising indicia carried by said plastic matrix, and means comprising said advertising indicia for concealing from sight at least said electric battery and reed switch.
Claim 2
Dependent Claim
194 words
An advertising device comprising a base and a manipulable display piece, said base having a clearly delineated supporting surface and a magnet concealed beneath said surface, said magnet having a pole eccentrically positioned with respect to the center of said delineated supporting surface, and said display piece having a lamp, an electric battery and a reed switch all connected in series with one another and all totally encapsulated within a solid plastic matrix, the outer surface of which is uninterrupted, said reed switch having an envelope and contact reeds within said envelope and movable with respect to one another in response to the presence of a magnetic field at said magnet pole, said reed switch being positioned within said piece to be physically isolated from said base surface when said piece is resting on said surface but to be exposed to said magnetic field for changing the position of the reed switch contact reeds relative to one another in at least one position of the piece on said base, advertising indicia carried by said plastic matrix, and means comprising said advertising indicia for concealing from sight at least said electric battery and reed switch.
Claim 3
Dependent Claim
43 words
The device of claim 1 wherein the said battery is rechargable and a recharging circuit, including transformer and rectifier means is totally encapsulated within the said matrix and concealed from sight by the said means for concealing said electric battery and reed switch.
Claim 4
Dependent Claim
136 words
An advertising device comprising a base and a manipulable display piece, said base having a supporting surface and a magnet concealed beneath said surface, said display piece having a lamp, a reed switch and a rechargable battery all connected in series with one another and a recharging circuit including a transformer coil and rectifying means electrically connected to said battery, all of said lamp, switch, battery and recharging circuit being totally encapsulated within a solid plastic matrix the outer surface of which is uninterrupted, said reed switch being responsive to a magnetic field of said magnet at at least one position of said display piece on said supporting surface, advertising indicia carried by said plastic matrix, and means comprising said advertising indicia, for concealing from sight at least said electric battery, reed switch and recharging circuit.
Claim 5
Dependent Claim
136 words
An advertising device comprising a base and a manipulable display piece, said base having a supporting surface and a magnet concealed beneath said surface, said display piece having a lamp, a reed switch and a rechargable battery all connected in series with one another and a recharging circuit including a transformer coil and rectifying means electrically connected to said battery, all of said lamp, switch, battery and recharging circuit being totally encapsulated within a solid plastic matrix the outer surface of which is uninterrupted, said reed switch being responsive to a magnetic field of said magnet at at least one position of said display piece on said supporting surface, advertising indicia carried by said plastic matrix, and means comprising said advertising indicia, for concealing from sight at least said electric battery, reed switch and recharging circuit.
