TennisschlägerTennis racket

Die Erfindung bezieht sich auf einen aus mehreren Schichten Holz und Vulkanfiber aufgebauten Tennisschläger.The invention relates to one of several layers Tennis racket made of wood and vulcanized fiber.

Um gut spielb^ar zu sein, müssen Tennisschläger gewisse Eigen-'■ schäften hinsichtlich Festigkeit und Elastizität aufweisen; auch ihr Gewicht muß innerhalb bestimmter Grenzen liegen und soll zum Beispiel für Herren-Schläger If Unzen nicht überschreiten. "■""■"- \ In order to be playable, tennis rackets must have certain properties in terms of strength and elasticity; their weight must also be within certain limits and should not, for example, exceed if ounces for men's rackets. "■""■" - \

Der Erfindung liegt die Aufgab-e zugrunde, einen Tennisschläger der genannten Art zu schaffen, der insbesondere für hohe Beanspruchungen ausgelegt ist.The invention is based on the object of creating a tennis racket of the type mentioned, which is particularly suitable for high Is designed to withstand stresses.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine oder mehrere Schichten aus glasfaserverstärktem KunststoffThis object is achieved in that a or several layers of glass fiber reinforced plastic

bestehen. Vorzugsweise besteht jede der beiden Außenschichten aus einem zusammenhängenden Belag aus glasfaserverstärktem Kunststoff j der die Oberflächen des Schaftes und des Kopfes vollständig bedeckt. Der Belag besitzt dabei vorteilhaft eine Dicke von 1,1 nun, exist. Preferably there is each of the two outer layers from a coherent covering made of glass fiber reinforced Plastic j which the surfaces of the shaft and the Head completely covered. The covering advantageously has a thickness of 1.1 now,

Es hat sich gezeigt, daß der erfindungsgemäße Tennisschläger verwindungsstabiler und verzugsfester ist als vergleichbare Schläger. Außerdem ist sein Schwingungsbereich kleiner, d.h. er ist haltbarer, denn das Material wird weniger beansprucht und die Ermüdungserscheinungen sind daher wesentlich geringer.It has been shown that the tennis racket according to the invention is more torsion-resistant and warp-proof than comparable Bat. In addition, its range of oscillation is smaller, i.e. it is more durable because the material is less stressed and the symptoms of fatigue are therefore much less.

In der Praxis hat sich überraschenderweise ergeben, daß der erfindungsgemäße Tennisschläger härter zurückfedert, was eine größere Ballbeschleunigung zur Folge hat oder - anders betrachtet - nur einen geringeren Kräfteeinsatz beim Spielen erfordert. Er weist überdies eine bessere Schlagdämpfung auf als Metallschläger und läßt sich auch (da er ja ein Holzschläger ist ) leichter besaiten als diese. In practice it has surprisingly been found that the tennis racket according to the invention springs back harder, which results in a greater acceleration of the ball, or otherwise considered - only requires less effort when playing. It also has better shock absorption as a metal racket and is also easier to string than this (since it is a wooden racket).
