Description

Bälle werden meist in Form eines halbregulären Polyeders angefertigt (sogenannter Europafußball).Balls are usually made in the form of a semi-regular polyhedron (so-called European football).

Dieser Körper besteht aus 12 regelmäßigen Fünfecken und 20 regelmäßigen Sechsecken - alle mit der gleichen Seitenlänge. Fußbälle werden also aus 32 Einzelteilen zusammengefügt.This body consists of 12 regular pentagons and 20 regular ones Hexagons - all with the same side length. So soccer balls are made up of 32 Individual parts put together.

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.The subject of this patent is the possibility to insert this polyhedron into one or divide several sub-areas, so that less for the production of the polyhedron Individual components are required.

Insbesondere ist hier die Möglichkeit gemeint, den besagten Polyeder in 4 oder 2 deckungsgleiche Teile zu zerlegen.In particular, the possibility of the said polyhedron in 4 or 2 is meant here disassemble identical parts.

Fig. 1 zeigt eine Möglichkeit, eines von vier deckungsgleichen Elementen zur Herstellung so eines Polyeders herzustellen. Fig. 2 zeigt eines von 2 deckungsgleichen Elementen. Fig. 1 shows a possibility of producing one of the four congruent elements for producing such a polyhedron. Fig. 2 shows one of two congruent elements.

Die Punkte 10 (20) müssen dabei jeweils mit den Punkten 11 (21) verbunden werden.Points 10 ( 20 ) must be connected to points 11 ( 21 ).

Claims (2)

1. 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.1. Semi-regular polyhedron (so-called. European football) characterized in that it is composed of individual elements, each consisting of several connected pentagons or hexagons. This reduces the number of connections to be made. 2. Halbregulärer Polyeder nach Anspruch 1, dadurch gekennzeichnet, daß die Oberfläche aufgeteilt ist in 2 oder 4 (Fig. 1) deckungsgleiche Elemente.2. Semi-regular polyhedron according to claim 1, characterized in that the surface is divided into 2 or 4 ( Fig. 1) congruent elements.
