Abstract

The device comprises (a) a pile of insulated plates separated by electrically conducting sheets, each conducting sheet being connected to a power source, and (b) a set of electric bulbs, each comprising a stem formed of two laterally protruding conducting parts insulated from each other and provided to be connected each to one of the conducting sheets through penetration of said stem in said pile.

Claims

1. Device for luminous animation, comprising at least one panel constituted by a pile of insulating plates of uniform width each separated by an electrical conducting sheet and equally spaced by said insulating plates, electrical junction means electrically connected to each electrical conducting sheet and leading respectively to at least one side of said panel to elEctrically interconnect the conducting sheets of a panel to the sheets of another panel and to outputs of an electrical supplying unit for each conducting sheet and rotatable lighting plugs each comprising a lighting member and a pin axially protruding with respect to said lighting member, said pin having two conductors and an electrically insulating wall at least partially surrounding one of them, and two electrically conducting elements each connected to a respective one of said conductors carried by said pin and laterally protruding therefrom on at least one side, said conducting elements being separated by a distance equal to the thickness of selected insulating plates, whereby said pin is inserted through said insulating plates and conducting sheets together with said two protruding conducting elements penetrating said conducting sheets for electrical contact therewith upon substantially 90* rotation of said pin.

2. Device as set forth in claim 1, wherein the protuberances comprise a conducting core and a conducting sleeve concentrically surrounding said core, said protruding conducting elements being substantially loganze-shaped, and respectively placed at a distance slightly greater than the distance separating an outer surface of the panel from the conducting sheets corresponding to said substantially lozange-shaped portions, whereby said conducting sheets are completely traversed by said substantially lozange-shaped portions which bear underneaath of said conducting sheets after a rotation of substantially 90* of said plug.

3. Device as set forth in claim 1, wherein the conducting sheets inserted between each pair of insulating plates have at least one stamping in a shape corresponding to cavities made into the insulating plates from at least one side thereof said stampings having also a shape appropriate to shape of a conducting socket encased in said stamping and into corresponding cavities of the adjacent isulating plates, conducting sticks and plugs being designed to be inserted into said sockets of two contiguous panels, whereby the conducting sheets of two panels which are at a same level are placed at the same electrical potential.

4. Device as set forth in claim 1, wherein the supplying unit comprises at least one supply source of electrical power, a conductor connecting at least one terminal of said supply source to that of the conducting sheets which is nearest of at least one large side of each panel, a control device connected to other terminal of the supply source, said a control device having distinct outputs respectively connected to each other conducting sheets of the panel.

5. Device as set forth in claim 1 wherein each plug comprises a conducting cylindrical core forming, at the lower portion thereof, a point shaped part of a substantially lozange shape, an insulating casing extending outside of the conducting core on at least a portion of the length of said core, a tubular sleeve surrounding said insulating casing and extending over only a portion of the length of said conducting core, said sleeve forming, at one end, a lozange-shaped portion and, at other end thereof, a widened portion;

an electric bulb constituting the lighting member and placed axially with respect to said conducting core, said bulb comprising a filament with a first conductor connected to said core and a second conductor of said filament being connected to said sleeve.

6. Device as set forth in claim 5, further comprising a light permeable cap covering said bulb and engaged on the periphery of said widened portion of said sleeve.

7. Device as set forth in claim 5, wherein electrical connection means are designed between said conducting core and said sleeve to prevent any relative motion of said conducting core relatively to said sleeve.

8. Device as set forth in one of claim 5, wherein the widened portion of said sleeve is insidely provided with an insulating block having at least one central bore and a lateral bore for passing wires Connected to the filament of said bulb, a pressure resilient washer pressing said wires against said insulating block and respectively against the inner wall of said widened portion and against a point shaped part extending the conducting core and placed inside the central bore of said block.

9. Device as set forth in claim 5, wherein said insulating casing surrounding the conducting core protrudes beyond the substantially lozange shaped portion of the sleeve placed concentrically to said conducting core, said insulating casing extending up to the substantially lozange shaped portion of said conducting core and having a diameter at the utmost equal to diameter of the sleeve.

10. Device as set forth in claim 5, wherein the insulating casing extending up to the spear-head shaped portion of the conducting core is designed with a diameter smaller than smallest size in width of said substantially lozange shaped portion, whereby said conducting casing has no friction against the material constituting the insulating plates and the conducting sheets of the panels when the plug has penetrated inside the same.

11. Device as set forth in claim 5, comprising a spring surrounding the sleeve placed concentrically to the conducting core and placed between top of each panel and widened portion formed by said sleeve to tend to lift said plug after engagement thereof into a panel by applying said substantially lozange shaped portion against the respective conducting sheets after penetration and rotation through 90* of said plugs.

12. Device as set forth in claim 5, wherein the conducting core and the conducting sleeve surrounding said core have each of them respectively two substantially lozange shaped portions, contiguous to each other and only separated by a narrow segment having a circular shape.
