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).

Abstract

The polyhedron consists of connected pentagons or hexagons. The surface is divided into two or four congruent elements.

Description

Bälle werden meist in Form eines halbregulären Polyeders angefertigt (sogenannter Europafussball).
Dieser Körper besteht aus 12 regelmäßigen Fünfecken und 20 regelmäßigen Sechsecken - alle mit der gleichen Seitenlänge. Fussbälle werden also aus 32 Einzelteilen zusammengefügt.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.

Gegenstand dieses Patentes ist die Möglichkeit, eben diesen Polyeder in einen oder mehrere Teilflächen aufzuteilen, so dass für die Herstellung des Polyeders weniger Einzelbestandteile benötigt werden.
Insbesondere ist hier die Möglichkeit gemeint, den besagten Polyeder in 4 oder 2 deckungsgleiche Teile zu zerlegen.
Fig. 1 zeigt eine Möglichkeit, eines von vier deckungsgleichen Elementen zur Herstellung so eines Polyeders herzustellen. Fig.2 zeigt eines von 2 deckungsgleichen Elementen.
Die Punkte 10 (20) müssen dabei jeweils mit den Punkten 11 (21) verbunden werden.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.
In particular, 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).

Claims (2)

Halbregulärer Polyeder (sog. Europafussball) dadurch gekennzeichnet, dass er aus Einzelelementen, die jeweils aus mehreren zusammenhängenden Fünf- bzw. Sechsecken bestehen, zusammengesetzt ist. Hierdurch wird die Zahl der herzustellenden Verbindungen reduziert.Semi-regular polyhedron (so-called European football) characterized in that it from individual elements, each consisting of several connected five or Hexagons are composed. This reduces the number of connections to be made. Halbregulärer Polyeder nach Anspruch 1, dadurch gekennzeichnet, dass die Oberfläche aufgeteilt ist in 2 oder 4 (Fig.1) deckungsgleiche Elemente.Semi-regular polyhedron according to claim 1, characterized in that the The surface is divided into 2 or 4 (Fig.1) congruent elements.
