Abstract

The ball for use in sports, and esp. a golf ball, is a hollow body of gelatine or a mixt. of gelatine with another biopolymer such as starch.

Description

Die Erfindung betrifft einen Spielball, insbesondere einen Golfball, wobei aber auch eine Verwendung für andere Ballspiele mit vorzugsweise kleinen Balldurchmessern, wie z.B. Tennis, Tischtennis oder Ping Pong in Frage kommt. Derartige Spielbälle müssen teilweise bezüglich Material und Verarbeitung hohe Anforderungen erfüllen und sind daher entsprechend kostspielig. Für Uebungszwecke würde in vielen Fällen eine einfachere und daher auch preiswertere Ausführung genügen. So muss beispielsweise für die Uebung der Treffsicherheit beim Golf der Golfball nicht zwingend das genau vorgeschriebene Gewicht aufweisen. Wenn Golfübungen nicht im freien Gelände durchgeführt werden, können die regelkonformen Bälle gar eine Gefahr für die Umgebung darstellen. Spielbälle, welche zu Uebungszwecken eingesetzt werden, unterliegen ausserdem einer raschen Abnutzung oder Beschädigung und müssen entsorgt werden. Bei herkömmlichen Spielbällen aus Kautschuk, Kunststoff, Filz und dergleichen ergibt sich daher abgesehen von den hohen Kosten auch noch ein ökologisches Problem.The invention relates to a game ball, in particular a golf ball, but also a use for other ball games with preferably small ball diameters, such as e.g. Tennis, table tennis or ping pong come into question. Such balls must meet high requirements in terms of material and workmanship and are therefore correspondingly expensive. For practice purposes, a simpler and therefore also cheaper version would suffice in many cases. For example, the golf ball does not necessarily have to have the precisely prescribed weight for the practice of accuracy in golf. If golf exercises are not carried out in open terrain, the compliant balls can even pose a danger to the environment. Play balls that are used for practice purposes are also subject to rapid wear or damage and must be disposed of. With conventional balls made of rubber, plastic, felt and the like, there is also an ecological problem in addition to the high costs.

Es ist daher eine Aufgabe der Erfindung, einen Spielball zu schaffen, der auf einfache und kostengünstige Weise hergestellt werden kann und der ausserdem nach Gebrauch einfach und problemlos entsorgt werden kann. Der Spielball soll insbesondere auch als Uebungsball eingesetzt werden können, wobei gegenüber regelkonformen Bällen bewusst andere Eigenschaften, wie z.B. geringeres Gewicht, andere Elastizität, u.s.w. angestrebt werden.It is therefore an object of the invention to provide a game ball which can be produced in a simple and inexpensive manner and which, moreover, can be disposed of easily and without problems after use. The game ball should in particular also be able to be used as an exercise ball, whereas other properties, such as e.g. lower weight, different elasticity, etc. be aimed for.

Diese Aufgabe wird mit einem Spielball gelöst, der die Merkmale im Anspruch 1 aufweist. Hohlkörper aus Gelatine oder aus einer Mischung aus Gelatine und einem anderen Biopolymer, wie z.B. Stärke, lassen sich äusserst preiswert herstellen. Dabei kann auf Verarbeitungsverfahren zurückgegriffen werden, die bereits in den Bereichen Pharma, Kosmetik oder Lebensmittel bekannt sind. So werden beispielsweise bereits flüssige Seifen oder auch Aromastoffe in Gelatinehüllen verkapselt, wobei auch die Kugelform bekannt ist. Bezüglich Einzelheiten der Kapselherstellung wird verwiesen auf Lachman/Lieberman/Kanig, "The Theory and Practice of Industrial Pharmacy", 3rd Edition, Philadelphia 1986, insbesondere auf das Kapitel "Capsules". Die Herstellung der Hohlkörper kann mit allen bekannten Verfahren wie z.B. mittels Formwalzen mit Füllkeil, Spritzgiessen u.s.w. erfolgen.This object is achieved with a game ball which has the features in claim 1. Hollow bodies made of gelatin or a mixture of gelatin and another biopolymer, such as starch, can be produced very inexpensively. Processing methods can be used that are already known in the fields of pharmaceuticals, cosmetics or food. For example, liquid soaps or flavorings are already encapsulated in gelatin shells, and the spherical shape is also known. With regard to details of the capsule production, reference is made to Lachman / Lieberman / Kanig, "The Theory and Practice of Industrial Pharmacy", 3rd Edition, Philadelphia 1986, in particular to the chapter "Capsules". The hollow bodies can be produced using all known methods, for example by means of shaping rolls with a filling wedge, injection molding, etc.

Spielbälle auf der Basis von Gelatine als Grundstoff sind ungiftig und biologisch abbaubar. Auch verlorene Bälle verunreinigen die Umwelt nicht, da sie mit der Zeit abgebaut werden. Durch Zugabe eines anderen Biopolymers bis zu 20 Gewichtsprozenten kann die Eigenschaft des Spielballs, insbesondere seine Härte beeinflusst werden. Sehr gute Resultate lassen sich dabei durch eine Zugabe von Stärke erzielen. Eine wesentliche Rolle spielt auch die gewählte Wandstärke des Spielballs. Kapseln und andere Hohlkörper aus Gelatine haben die Eigenschaft, dass sie nach der Verarbeitung aushärten und dabei schrumpfen. Das Mass der Schrumpfung hängt dabei vom verarbeiteten Materialvolumen ab. Ein Spielball mit grösserer Wandstärke wird daher auch mehr schrumpfen, als bei einer geringeren Wandstärke. Dieses Materialverhalten kann ausgenutzt werden, um die Elastizität des Spielballs zu beeinflussen. Da der Hohlkörper praktisch gasdicht ist, führt eine starke Schrumpfung zu einer Komprimierung des Innenvolumens und damit zu einer grosseren Härte.Playballs based on gelatin as a raw material are non-toxic and biodegradable. Even lost balls do not pollute the environment, as they are broken down over time. The property of the game ball, in particular its hardness, can be influenced by adding another biopolymer of up to 20 percent by weight. Very good results can be achieved by adding starch. The selected wall thickness of the game ball also plays an important role. Capsules and other hollow bodies made of gelatin have the property that they harden and shrink after processing. The degree of shrinkage depends on the volume of material processed. A game ball with a larger wall thickness will therefore shrink more than with a smaller wall thickness. This material behavior can be used to influence the elasticity of the game ball. Since the hollow body is practically gas-tight, a strong shrinkage leads to a compression of the inner volume and thus to a greater hardness.

Die Oberfläche des Spielballs kann strukturiert sein, um ein bestimmtes Abrollverhalten zu erzielen. Die Oberfläche kann aber auch mit einer hydrophobierenden Schicht überzogen sein, um eine erhöhte Resistenz gegen Feuchtigkeit zu erreichen.The surface of the game ball can be structured in order to achieve a certain rolling behavior. However, the surface can also be covered with a hydrophobic layer in order to achieve increased resistance to moisture.

Der Hohlkörper kann mit Luft gefüllt sein, wie dies bei bekannten Spielbällen der Fall ist. Die bekannten Verarbeitungsverfahren für Gelatine-Hohlkörper erlauben aber auch ein Füllen des Hohlkörpers mit einer Flüssigkeit oder gar mit einem Feststoff. So wäre es beispielsweise denkbar, für einen Uebungsball aus Gelatine mit einer entsprechenden Befüllung exakt das gleiche Gewicht zu erreichen, wie bei einem regelkonformen Ball aus Kautschuk. Auch die Stabilität kann mit einer entsprechenden Füllung erhöht werden, wobei die Füllung vorzugsweise ebenfalls aus einem biologisch abbaubaren Stoff besteht.The hollow body can be filled with air, as is the case with known game balls is the case. The known processing methods for gelatin hollow bodies also allow the hollow body to be filled with a liquid or even with a solid. For example, it would be conceivable to achieve exactly the same weight for an exercise ball made of gelatin with an appropriate filling as for a rubber ball that complies with the rules. The stability can also be increased with a suitable filling, the filling preferably also consisting of a biodegradable substance.

Um den erfindungsgemässen Spielball auch in ästhetischer Hinsicht optimal zu gestalten, könnte der Hohlkörper schliesslich auch mit einem Farbstoff durchgefärbt sein. Dabei kommen insbesondere Lebensmittelfarbstoffe in Frage, welche ungiftig sind.In order to optimally design the game ball according to the invention also from an aesthetic point of view, the hollow body could finally be colored through with a dye. Food dyes that are non-toxic are particularly suitable.

Die einzige Darstellung zeigt einen teilweise aufgebrochenen Golfball bestehend aus dem Hohlkörper 1 mit einer Wandstärke W. Die Oberfläche weist eine Strukturierung 2 in der Form von flachen Vertiefungen auf.The only illustration shows a partially broken golf ball consisting of the hollow body 1 with a wall thickness W. The surface has a structure 2 in the form of shallow depressions.
