Abstract

The present invention relates to a selectively conductive toy building element, comprising: a body adapted for releasable engagement to at least one other toy building element body or to a corresponding baseplate, the body including at least one conductive portion having at least one contact area adapted to generate pressure on a conductive portion or contact area of an adjacent toy building element body, in such a way that ensures electrical conduction between said toy building elements in a desired location and direction.

Claims

1. A selectively conductive toy-building element, comprising:

a body adapted for releasable engagement to at least one other toy-building element body or to a corresponding baseplate, wherein the body has an upper portion, a lower portion and a plurality of sides extending between the upper and lower portions, each side having an inner surface and an outer surface, the outer surface of at least one of the sides including at least one conductive portion comprising an elastic arm that is attached at one end to the outer surface of said body and extends away from the outer surface, the elastic arm including at least a partial contact area having a conductive coating, wherein the elastic arm is adapted to generate pressure on an outer surface of an adjacent toy-building element by allowing displacement toward or away from the body, thereby avoiding an air gap between said elements and ensuring electrical conduction between said toy-building elements in a desired contact location and selected direction whenever the at least partial contact area with the conductive coating of the elastic arm of said toy-building element contacts a conductive portion or contact area on the surface of said adjacent toy-building element.

2. The toy-building element according to claim 1, wherein the conductive portion comprises a coating of one or more layers of metals selected from copper, nickel and chrome.

3. The toy-building element according to claim 1, wherein the contact area extends outwardly from the outer surface of the body of the toy-building element.

4. The toy-building element according to claim 1, wherein the upper portion has a top attachment surface and the lower portion has a bottom attachment surface, each of which surfaces are configured for releasable engagement with complementary attachment surfaces of other toy-building elements.

5. The toy-building element according to claim 4, wherein at least one of the top attachment surface and the bottom attachment surface of the upper portion and the bottom portion, respectively, include a conductive coating for use as a contact area.

6. The toy-building element according to claim 4, wherein the top attachment surface has a portion that extends outwardly, resulting in a building element having an angular structure, such that said extended portion forms a 90 degree angle with a side portion of the body, thereby allowing said extended portion to be used as a contact area.

7. The toy-building element according to claim 1, wherein the elastic arm is defined by a contact area of the toy-building element that is flexible or elastic in order to assure physical contact when pressed sideways with another toy-building element.

8. The toy-building element according to claim 7, wherein the elastic arm is embedded so that at least one contact area of the toy-building element comprises one or more embedded elastic or flexible arms that extend away from the body of the element.

9. The toy-building element according to claim 8, wherein the flexible arm is connected to the body only from one end in order to increase its flexibility.

10. The toy-building element according to claim 1, wherein the contact area has a rounded shape, thereby assuring smooth connectability to an adjacent toy-building element.

11. The toy-building element according to claim 1, further comprising a plastic component having a plastic compartment and at least one electrical component housed inside the plastic compartment which is coupled to the body of the element, wherein said at least one electrical component includes at least one electrical contact electrically connected to a corresponding contact area at said body, either directly or via a wiring arrangement.

12. The toy-building element according to claim 11, wherein the electrical component includes or is coupled to at least one current limiting and/or current monitoring component.

13. A method of manufacturing a selectively conductive toy-building element, comprising:

creating a connectable brick comprised of a non-conductive material and which includes a top portion, a bottom portion and a plurality of sides extending between the top and bottom portions, each side having an inner surface and an outer surface, the outer side surface of at least one of the sides comprising at least one elastic arm that is attached to said outer side surface at one end, extends outwardly from said outer side surface and is adapted to generate pressure on a side portion of an adjacent building element that includes a conductive portion or contact area; and

coating at least one section of said brick with a conductive layer, wherein said section includes said at least one elastic arm, thereby converting said at least one elastic arm into a conductive contact area.

14. The method according to claim 13, further comprising repeating the coating with an additional metallic conductive layer.

15. The method according to claim 13, wherein the coating is applied using lithography techniques.

16. The method according to claim 15, wherein the lithography techniques involve etching the metallic layers from certain areas on the brick.

17. The method according to claim 13, wherein the coating is applied by attaching fully conductive and non-conductive parts to form a single brick.

18. A kit comprising:

a plurality of selectively conductive toy-building elements, each of said toy-building element comprising a body adapted for releasable engagement to at least one other toy-building element body or to a corresponding baseplate, the body having a top portion, a bottom portion and a plurality of sides extending between the top and bottom portions, each side having an inner surface and an outer surface, the outer surface of at least one of the sides including at least one conductive portion comprising an elastic arm that is attached at one end to the outer surface of said body and extends away from the outer surface, the elastic arm including at least a partial contact area having a conductive coating and which is adapted to generate pressure on a conductive portion or contact area of an adjacent toy-building element body by allowing displacement toward or away from the body to ensure electrical conduction between said toy-building elements in a desired location and direction;

a plurality of non-conductive toy-building elements; and

base plates and accessories of toy-building systems.
