Definitions

  • Balls are usually made in the form of a semi-regular polyhedron (so-called European football). This body consists of 12 regular pentagons and 20 regular hexagons - all with the same side length. So soccer balls are put together from 32 individual parts.
  • the subject of this patent is the possibility of dividing this polyhedron into one or more partial surfaces, so that fewer individual components are required for the production of the polyhedron.
  • the possibility of disassembling said polyhedron into 4 or 2 congruent parts is meant here. 1 shows one possibility of producing one of four congruent elements for producing such a polyhedron.
  • Fig. 2 shows one of two congruent elements. Points 10 (20) must be connected to points 11 (21).
