Abstract

Building block system, magnetically held together, comprising a base plate (1) and at least one building block (2). The base plate (1) comprises a magnetizable metal core (3) and at least one building block (2) comprises at least one magnetizable metallic joining element (4) placed inside the building block. The metal core (3) of the building block system is preferably electrically magnetizable and the parts of the system have smooth surfaces.

Claims

1. A building block system comprising:

a base plate comprising;

a magnetizable metal core;

a plurality of joining elements comprised of metallic material attached to said core and disposed from one another by a modular measure, said joining elements having a surface which lies farthest from said core,

non-magnetic isolating material attached to and covering said core, said isolating material having a surface distal said core, such that said surface of said joining elements of said base plate is flush with said surface of said isolating material such that said surface of said isolating material and said surface of said joining elements of said base plate create a smooth surface throughout;

a means for electrically magnetizing said core and said joining elements of said base plate; and

a plurality of building blocks, each block having a first surface and at least one joining element that extends to said first surface of said building block.

2. A building block system according to claim 1 wherein said joining elements of said base plate comprise pegs that protrude from the surface of said metal core, said pegs having space therebetween, and wherein said isolating material fills said space between said pegs of said base plate.

3. A building block system as in claim 2 wherein each said peg of said base plate has a circular cross-section.

4. A building block system according to claim 1 wherein each said joining element of each said building block is configured as a peg.

5. A building block system according to claim 4 wherein each said peg of each said building block has a circular cross-section.

6. A building block system according to claim 1 wherein each said building block further comprises a second surface opposing said first surface and each said joining element of said building block comprises a pair of end surfaces, said joining element extending through said building block such that each said end surface of said joining element is flush with a corresponding one of said first and second surfaces of said building block such that said first and second surfaces of said building block are smooth throughout.

7. A building block system according to claim 1 wherein said building block contains a plurality of said joining elements, said distance between said joining elements being a modular measure.

8. A building block system according to claim 1 wherein said electrically magnetizing means comprises a coil wound around said core of said base plate, said coil being connected to a power supply via a switch.

9. A building block system according to claim 8 wherein said switch is a reversing switch.
