INTERLOCKING BUILDING BLOCKS AND SYSTEM USING THE SAME Abstract of the Disclosure A family of interlocking polyurethane foam building blocks configured similarly to conventional concrete building blocks. Tongues and grooves are formed on the end faces of a universal block in such a manner that the end faces of two identical blocks will engage with one another when the blocks are longitudinally aligned and the end faces are in abutment. The tonguesand grooves are configured so that the building blocks may be rotated about any axis of the block and still interlock with an identical block. The upper and lower surfaces of the universal block are formed with projections and recesses configured to engage with the projections and recesses on an abutting surface ofan identical block that is longitudinally offset by one-half the length of the block. The projections and recesses are configured and arranged to allow the universal block to be rotated about any axis of the block and still interlock with an identical block. A corner block, half block, three-quarter block, pilaster block, and bond beam block constitute the rest of the family of building blocks.These blocks are configured to interlock with the universal block and allow construction of a walled structure using conventional concrete block building techniques.
