Definitions

  • This invention relates to rings of tetrahedral bodies, each body having two opposed edges hinged to edges of respective tetrahedral bodies adjacent in the ring.
  • one aspect of the invention provides a body comprising two part-tetrahedral bodies separate or separable from other part-tetrahedral bodies with which respective tetrahedral bodies can be assembled, said two part-tetrahedral bodies being joined hingedly between edges corresponding to edges or part edges of the respective tetrahedral bodies.
  • joins need to be made only between parts which do not move relative to one another, the hinge being already provided.
  • the body including the hinge may be conveniently moulded in one piece from a suitable plastics material.
  • the two part-tetrahedral bodies are identical. More preferably, a tetrahedral body may be assembled from a plurality of identical ones of said part-tetrahedral bodies. For example, if a tetrahedral body can be constructed from two of the part-tetrahedral bodies, the whole ring can be constructed from a set of identical bodies.
  • a tetrahedral body may be assembled from four of said part-tetrahedral bodies. As will be explained this enables rings of rings to be constructed using a set of identical bodies.
  • the body may be at least partly skeletal.
  • the body provides surfaces corresponding to those of the respective part-tetrahedra.
  • Each part-tetrahedral body may be provided with means for joining to another part or to other parts of the same respective tetrahedral body.
  • the means for joining may comprise permanent magnets.
  • the invention also extends to a ring of rings of tetrahedral bodies, each body having two opposed edges hinged to edges of respective tetrahedral bodies adjacent in the ring of bodies, edges hinged to one another within the ring of bodies being also hinged to corresponding edges in rings of bodies adjacent in the ring of rings.
  • Edges hinged to one another within rings of bodies may also hinged to corresponding edges in other rings of bodies to form a plurality of rings of rings.
  • each ring of bodies preferably contains 6 tetrahedral bodies.
  • each ring of rings preferably contains 3 or 4 rings.
  • a tetrahedron 2 is shown in Figure 1a. It is desired to construct a ring of tetrahedra in which two opposite edges, e.g. 2 and 4, are hinged to corresponding edges of other tetrahedra adjacent in the ring.
  • the basic building block of this embodiment consists of a body 9 comprising two such parts 8 joined at their portion of the edges 4 and 6 by a hinge 10.
  • the part tetrahedra 8 are moulded from suitable plastics material, with an integral thin web 12 joining them to provide the hinge 10.
  • the body is skeletal, e.g. each of the edges illustrated in the drawings representing a frame member.
  • two of the bodies are joined at their faces 12 as shown in Figure 2a, two half-tetrahedra are formed hinged at their faces 6 and 4 if two such assemblies, suitably oriented, are joined at their faces 14, a tetrahedron is formed in the centre, leaving two half-tetrahedra at the ends.
  • Addition of further such assemblies to a minimum total of 6, enables the ends to be joined to form a ring of tetrahedra. This has the interesting property that it can be turned through its own centre, as is known.
  • the basic building block could be the hinged half-tetrahedra illustrated in Figure 2a and formed in one piece instead of the two pieces illustrated.
  • the half- or quarter-tetrahedra may be joined by any suitable means. They may, for example, be permanently cemented together. If it is desired to be able to dissemble the construction, for example, as a toy or puzzle, the surfaces to be joined may by provided with complementary male and female members. In the present embodiment, however, the faces to be joined have permanent magnets either in or behind them.
  • FIG 6 there are illustrated 8 rings each of 6 tetrahedra 2.
  • the rings 16 are hingedly connected in rings of four, so forming three rings of four, as illustrated.
  • tetrahedra need to be hingedly connected to three other tetrahedra. This is not possible with the arrangement shown in Figure 2a.
  • the tertrhedra may be constructed and hinged in any suitable way and may be partly or wholly skeletal. Most preferably, in order to provide hinge connections between four tetrahedra, part tetrahedra are arranged as illustrated in Figures 2b to 5. Referring to Figures 2b and 3, the tetrahedron is constructed, as previously from part-tetrahedra 8a to 8d. The free part-tetrahedra 8e and 8f are not connected together, however, nor are the part-tetrahedra 8g and 8h.
  • another body 9d is then assembled on the structure with its part-tetrahedra 8k and 8l fixed to the part-tetrahedra 8j and 8f respectively.
  • Two more part-tetrahedra are similarly assembled on each of the free half-tetrahedra in Figure 5.
  • the arrangement gives a hinge connection between four tetrahedra.
  • the arrangement shown in Figure 6 provides three interconnected rings each of four rings of six tetrahedra.
  • the arrangement has the property of being flexible, that being allowed by the hinges.
  • the hinges allow the arrangement to be flexed. Flexing the arrangement causes it to self assemble into a geodesic dome or complete sphere as illustrated in Figure 7. If such a dome or sphere is used in the construction industry, the tetrahedra will most likely be skeletal.
  • a dome would require constraining, e.g. by ties, in order to prevent it flattening out.
