Interlocking building brick for toy sets - has metallic cover sections to give electrically conducting path

摘要

Building bricks which are made from a flexible plastic material, consist of a main component with cylindrical depressions on one side and cylindrical protrusions on the other side. Several blocks can be pushed together to form a structure. Some of the blocks in a set can be provided with electrically conducting surfaces and conductors which connect these surfaces. This makes it possible to incorporate an electrical path in a structure which can be used for miniature lighting, or for diving toy vehicles. Conducting and non-conducting parts are differently coloured.
