ABSTRACT:
A modular construction block comprising a configuration built up from five indentical rectangular sub-blocks dimensioned in the ratio of 1:2:4 and assembled into an "H"-shaped symmetric block about either of two vertical perpendicular planes through the center of the block.
The assemblage provides an "H"-shaped block wherein all external dimensions, slots and recesses are integer multiples of the minimum sub-block dimension. The blocks can be assembled together in a very wide variety of combinations to create utilitarian or decorative structures. The blocks may be sized for toy construction sets or for full sized building projects. The blocks may be formed of wood, plastic, metal, concrete or ceramic depending upon size and use.
