Description

Die Erfindung betrifft eine Münze mit einem, ein erstes Metall aufweisenden Zentralteil und einer diesen Zentralteil umgebenden Einfassung.The invention relates to a coin with a central part and a first metal a border surrounding this central part.

Münzen müssen ferromagnetische Werkstoffe enthalten, da z.B. in Verkaufsautomaten eingebaute Münzprüfer zur Überprüfung der Echtheit der Münze deren spezifisches magnetisches Moment messen. Dafür eignet sich Nickel besonders gut bzw. wurde bei Münzen der eingangs angeführten Bauart bislang in der Regel der Zentralteil in drei Schichten aus diesem Metall und Legierungen mit diesem Metall hergestellt. Es hat sich herausgestellt, dass bei Verwendung von solchen Nickel-Teile aufweisenden Münzen möglicherweise Nickelallergie und die mit einer solchen Allergie verbundenen Symptome auftreten.Coins must contain ferromagnetic materials, e.g. in vending machines built-in coin validator to check the authenticity of the specific coin measure magnetic moment. Nickel is particularly suitable for this or was used for Coins of the type mentioned above have so far generally been the central part in three Layers made of this metal and alloys made with this metal. It has found that when using such nickel-containing coins possibly nickel allergy and the symptoms associated with such an allergy occur.

Es ist Aufgabe der Erfindung, eine Münze der eingangs angeführten Art anzugeben, welche konstruktiv sehr einfach aufgebaut ist und bei welcher der aus Nickel oder sonstigem Benutzer und/oder Umwelt beeinträchtigendem ersten Metall bestehende Teil vollständig gegen die Umwelt abgeschlossen ist.It is an object of the invention to provide a coin of the type mentioned, which is structurally very simple and in which the nickel or other User and / or environmental impact of the first metal existing part completely against the environment is complete.

Erfindungsgemäß wird dies dadurch erreicht, dass der Zentralteil einen aus dem ersten Metall gebildeten Kern sowie zwei, diesen Kern zwischen einander einschließende Deckschichten aufweist.According to the invention, this is achieved in that the central part is made of the first metal formed core and two outer layers enclosing this core between each other having.

Damit wird zuverlässig verhindert, dass der aus dem ersten Metall bestehende Teil der Münze mit der Umwelt bzw. mit der Haut der Benutzer in Kontakt kommt. Nachteilige Folgen derartiger Berührungen, wie insbesondere Nickelallergie, werden vermieden. Trotzdem ist eine einwandfreie automatische Überprüfung der Münze mit den bisher verwendeten Münzprüfern möglich.This reliably prevents the part of the coin consisting of the first metal comes into contact with the environment or with the skin of the user. Adverse consequences such touches, in particular nickel allergy, are avoided. Still is a flawless automatic check of the coin with the previously used Coin validators possible.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, dass der Kern aus reinem Nickel besteht.According to a particularly preferred embodiment of the invention, that the core is made of pure nickel.

Dieses Metall eignet sich besonders gut für automatische Münzprüf-Verfahren, welche auf dem Prinzip der Vermessung von magnetischen Eigenschaften der Münze basieren.This metal is particularly suitable for automatic coin validation processes, which are based on based on the principle of measuring the magnetic properties of the coin.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, dass die Deckschichten aus reinem Titan bestehen. In a further embodiment of the invention it can be provided that the cover layers made of pure titanium.

Dieses Metall ist leicht, von silberweißer Farbe, korrosionsbeständig und weist eine optisch ansprechende Oberfläche auf. Darüber hinaus hat Titan bei Berührung keine negativen Auswirkungen auf den menschlichen Körper und ist somit ein optimaler Münz-Werkstoff.This metal is light, of silver-white color, corrosion-resistant and has an optical appealing surface. In addition, titanium has no negative effects when touched Effects on the human body and is therefore an optimal coin material.

Ein weiterer Vorteil des Titan besteht darin, dass der Messwert der elektrischen Leitfähigkeit von Titan, bei fast keinem anderen Metall auftritt. Dadurch ist der Werkstoff Titan eindeutig identifizierbar. Die Leitfähigkeit von Münzwerkstoffen ist einer der wesentlichsten Parameter bei der Identifizierung durch das automatische Münzprüf-Verfahren im Verkaufsautomaten. Weiters hat der Werkstoff Titan beim Prägen der Münze, dem sogenannten Flachfließ-Pressen, sehr gute Eigenschaften, welche, bei optimiertem Münzrelief, keinen sehr hohen Prägedruck verlangen und damit hohe Münzstempel-Standzeiten gewährleisten.Another advantage of Titan is that it measures the electrical conductivity of titanium, occurs with almost no other metal. This makes the material titanium unique identifiable. The conductivity of coin materials is one of the most important parameters with the identification by the automatic coin check procedure in the vending machine. Furthermore, the material titanium has been used for minting the coin, the so-called flat extrusion, very good properties which, with an optimized coin relief, are not very high Require embossing and thus guarantee a long coin life.

Es kann vorgesehen sein, dass der Zentralteil im Grundriss kreisförmig ausgebildet ist; weiters kann vorgesehen sein, dass die Einfassung im Grundriss kreisringförmig ausgebildet ist.It can be provided that the central part is circular in plan; it can also be provided that the border is circular in shape in the plan is.

Diese Formen sind besonders einfach herzustellen bzw. können sie sehr einfach zu einer vollständigen Münze miteinander verbunden werden.These shapes are particularly easy to manufacture or can be easily combined into one the whole coin.

Die Erfindung wird unter Bezugnahme auf die beigeschlossenen Zeichnungen, in welchen besonders bevorzugte Ausführungsbeispiele dargestellt sind, näher beschrieben. Dabei zeigt:

  • Fig. 1 eine erfindungsgemäße Münze im Querschnitt und
  • Fig.2 die Münze nach Fig. 1 im Grundriss.
  • The invention is described in more detail with reference to the accompanying drawings, in which particularly preferred exemplary embodiments are shown. It shows:
  • Fig. 1 shows a coin according to the invention in cross section and
  • 2 shows the coin according to FIG. 1 in plan.
  • Wie aus Fig.1 hervorgeht, hat eine erfindungsgemäße Münze einen Zentralteil 1, welcher von einer Einfassung 2 umgeben ist. Eine derartige Bauform weisen beispielsweise die 1-Euro-Münzen auf. Der Zentralteil 1 ist bei diesen als einstückiger, aus Nickel und NickelLegierung bestehender Flachzylinder ausgeführt.As can be seen from FIG. 1, a coin according to the invention has a central part 1, which of a surround 2 is surrounded. The 1 euro coins, for example, have such a design on. The central part 1 is in one piece, made of nickel and nickel alloy existing flat cylinder.

    Erfindungsgemäß ist dieser Zentralteil 1 schichtartig aufgebaut: Er weist einen aus reinem Nickel gebildeten Kern 10 sowie zwei Deckschichten 11 auf, welche diesen Kern 10 zwischen einander einschließen. Die Deckschichten 11 sind aus reinem Titan gebildet. Durch diesen Aufbau ist der Kern 10 allseitig, nämlich an seinen Stirnseiten von den Deckschichten 11 und an seinem Mantel von der Einfassung 2, umschlossen, womit Berührungen des Kerns 10 ausgeschlossen sind.According to the invention, this central part 1 is constructed in layers: it has one made of pure Nickel-formed core 10 and two cover layers 11 which cover this core 10 enclose between each other. The cover layers 11 are formed from pure titanium. By this structure is the core 10 on all sides, namely on its end faces from the cover layers 11 and on its jacket by the enclosure 2, which touches the core 10 are excluded.

    Die Erfindung dient in erster Linie dazu, Berührungen von in Münzen enthaltenem Nickel zu verhindern. Das dazu eingesetzte Prinzip, den Nickel-Kern 10 allseitig mit anderen Metallen zu überdecken, lässt sich aber auf andere Metalle übertragen, was bedeutet, dass der Kern 10 auch aus einem anderen, insbesondere einem Benutzer und/oder Umwelt beeinträchtigendem und deshalb vollständig einzuschließendem Material gebildet sein kann.The primary purpose of the invention is to touch nickel contained in coins prevent. The principle used for this, the nickel core 10 on all sides with other metals but can be transferred to other metals, which means that the core 10 also from another, in particular a user and / or environment impairing and therefore material to be fully enclosed can be formed.

    Die Einfassung 2 besteht in der Regel aus einem anderen Metall als der Zentralteil 1, womit die Münze zweifärbig ist.The border 2 is usually made of a different metal than the central part 1, with which the coin is two-colored.

    Der Zentralteil 1 ist beim in den Zeichnungen dargestellten Ausführungsbeispiel im Grundriss kreisförmig, die Einfassung 2 im Grundriss kreisringförmig. Von diesen geometrischen Gestalten kann aber abgewichen werden. So kann der Zentralteil 1 einen kreisförmigen Grundriss aufweisen. Die äussere Mantelfläche der Einfassung 2 kann von der Kreisform abweichen und einen mehreckigen Verlauf haben.The central part 1 is in the embodiment shown in the drawings in plan circular, the border 2 circular in plan. Of these geometrical But design can be different. So the central part 1 can be circular Show floor plan. The outer lateral surface of the border 2 can be of circular shape deviate and have a polygonal course.
