Abstract:
A modular construction unit comprising an assembly of a multiplicity of interlocking blocks, at least one of said blocks comprising, on at least one male end, a male element adapted to be introduced partially and held in place in a concave female element provided in another one of said blocks, whereinsaid male element comprises at one end thereof, a first part having in section an essentially circular form of a selected diameter Z and a locking part having in section an essentially square form of larger section to create at longitudinal ends of the first part protruding planes S1 and S2, the length of sides of the square form being essentially equal to the diameter Z of the first part and said female element having an opening having in section an essentially square form and creating a protruding plane P1, the length of sides of the square form being essentially equal to the diameter Z of the first part, as well as at least one cavity having a section larger than the section of the opening and creating a protruding plane P2, to enable rotation R of the protruding planes S1 and S2, respectively, on the protruding planes P1 and P2, or vice versa.
