Definitions

  • ABSTRACT A construction set comprises a plurality of skeletal tetrahedrons and interconnecting means therefor '50 that they can be assembled in a plurality of groups of different configuration and rotated relative to each other.
  • the legs of the tetrahedrons have flange configurations for receiving correspondingly flanged resilient connectors.
  • the present invention relates to a construction set comprising a plurality of identical pieces and means for interconnecting them in any of a plurality of combinations, as well as to individual pieces of the set.
  • the construction set of the present invention is useful not only for amusement purposes, but also for educational purposes.
  • FIG. 1 is a perspective view of a skeletal tetrahedron according to the invention
  • FIG. 2 is a nested stack of tetrahedrons adapted to rest on a flat surface
  • FIG. 3 shows a tripod receiving a skeletal tetrahedron point down
  • FIG. 4 is an enlarged fragmentary cross-sectional view on line A-B of FIG. 1 showing the cooperation between the tetrahedrons and the connector means;
  • FIG. 5 is a perspective view of a modified form of coupling element
  • FIG. 6 is a perspective view of still another form of coupling element
  • FIG. 7 is a view in perspective showing five tetrahedrons according to the present invention in assembled relationship.
  • FIG. 8 is a view similar to FIG. 7 but showing five more tetrahedrons added to the assembly.
  • FIG. 1 there is shown a skeletal tetrahedron according to the present invention, comprising six legs 9, three of which define each of the four flat triangular faces of the tetrahedron.
  • FIG. 2 shows a plurality of tetrahedrons in nested relationship; while FIG. 3 shows one of the tetrahedrons supported point down on a hollow triangular tripod.
  • Each leg 9 has on its inner edge a part-cylindrical recess 10 for the reception of at least half of a cylindrical flange ll ofa connector 12 (FIG. 4), and a concavely circular chamfer 13 along its opposite inner edge for the reception of a flange 14 on connector l2.-
  • the rib 11 and flange 14 thus bridge the flat inner edge 9' of the adjacent legs 9, as seen in FIG. 4.
  • Connector 12 is of resilient material and is bisymmetric on opposite sides of the plane on which two interconnected tetrahedrons meet, the tetrahedrons thus being rotatable relative to each other about the axis of connector 12.
  • FIG. 5 shows an alternative form of resilient connector 15 in the form of a triangular sleeve insertable in the triangular openings delimited by the edges 9' of the legs 9, each outer face of the triangular sleeve having ribs 11' corresponding to the ribs 11 of connector 12 and flanges 14 corresponding to the flanges 14 of the connector 12 and performing the same functions as in the case of connector 12.
  • the connector 15 is useful when the tetrahedrons are to be maintained in registry with each other and does not permit rotation of the tetrahedrons relative to each other.
  • FIG. 6 shows still another form of connector, which bridges an intermediate tetrahedron.
  • FIGS. 2, 7 and 8 Several of the configurations which the tetrahedrons may have in assembly, for amusement or educational purposes, are shown in full and phantom lines in FIGS. 2, 7 and 8.
  • a tetrahedron comprising six legs, each leg being interconnected at each end to two other legs, said legs being spaced apart intermediate their length, each side of the tetrahedron having a triangular opening therethrough bounded by three said legs, each leg having a part-circular recess midway of its length on an inner edge of each leg, and a connector member having one end engaged in one of said triangular openings and having a circular flange adjacent said one end and disposed in said part-circular recesses adjacent said one triangular opening.
