  • Modular construction block
    Patent number: 4928469
    Abstract: A modular block for making constructions, is essentially characterized by the fact that it comprises a body (1) having three groups of cylindrical hollows opening out respectively into three contiguous faces (2, 3, 4) of the cube, each group comprising at least two cylindrical hollows each of whose generator line is perpendicular to the face into which they open out, the two hollows including at least two lines in common and the section of each of them in a plane parallel to the face forming a partially closed curved surface suitable for preventing a cylinder of complementary shape to the corresponding hollow from radial displacement when such a cylinder is slid into said hollow. The invention is particularly applicable to building full scale models.
