Abstract

To increase the holding capacity (grip capacity) of the striking hand on the racket grip when striking the ball, the stabiliser is mounted in the lower region of the racket grip at the required distance from the end of the racket grip for the respective player. Due to the grip channel (1) which runs obliquely over several grip surfaces and has concave and convex surfaces, tensile and compression force of the index finger and thumb, which are stressed particularly when striking the ball, can be converted optimally by placing said finger and thumb in the grip channel (1), thus increasing the holding capacity of the striking hand. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung, die es dem Spieler erleichtert, beim Schlagen des Balles z.B. beim Tennis, das Halten des Schlägers zu verbessern.The present invention relates to a device which makes it easier for the player to improve the holding of the racket when hitting the ball, for example in tennis.

Der Stand der Technik in der Praxis sieht so aus, daß es für den beim Schlagen des Balles besonders beanspruchten Zeigefinger bzw. Daumen keine Vorrichtung gibt.The prior art in practice is such that there is no device for the index finger or thumb that is particularly stressed when hitting the ball.

Die im Patentbereich vorhandenen Vorrichtungen konnten sich offen­sichtlich wegen konstruktiven Mängeln (z.B. Griffstabilisatoren für die einzelnen Finger) nicht durchsetzen. Aufgabe der Erfindung war es daher eine Vorrichtung (Stabilisator) zu schaffen, der diese Nach­teile behebt und ihre Verwendung den Erfordernissen der Spielpraxis Rechnung trägt.The devices available in the patent area were obviously unable to assert themselves due to design defects (eg grip stabilizers for the individual fingers). The object of the invention was therefore to provide a device (stabilizer) which overcomes these disadvantages and their use takes account of the requirements of gaming practice.

Die vorliegende Erfindung löst diese Aufgabe dadurch, daß der Stabi­lisator einen bogenförmigen schräg über mehrere Griffflächen laufen­den Griffkanal mit konkaven und konvexen Flächen aufweist, dadurch eine bessere, größere Halte- und Gegendruckfläche schafft, die durch Zeigefinger und Daumen je nach Spielerfordernis (Vor-, Rückhand oder Aufschlag) beansprucht werden kann. Der Spieler braucht lediglich Zei­gefinger oder Daumen in den Griffkanal zu legen oder während des Spie­les durch Drehen der Schlaghand hineinzuführen.The present invention solves this problem in that the stabilizer has an arcuate grip channel running obliquely over several grip surfaces with concave and convex surfaces, thereby creating a better, larger holding and counter-pressure surface, which can be used by index finger and thumb depending on the game requirements (forehand, backhand or surcharge) can be claimed. The player only needs to put his index finger or thumb in the grip channel or insert it by turning the striking hand during the game.

Es ist beabsichtigt den Stabilisator auch nur für die einzelnen Griffe (Vorhand, Rückhand, Aufschlag) herzustellen.It is also intended to manufacture the stabilizer only for the individual grips (forehand, backhand, serve).

Damit der Stabilisator je nach den persönlichen Bedürfnissen des Spie­lers am Schlägergriff ohne Rücksicht auf die unterschiedliche Breite der Schlägergriffflächen angebracht werden kann, ist weiter beabsich­tigt, den Stabilisator mit minim breiten, bodentiefen Einschnitten in Längsrichtung herzustellen, um dadurch eine erhebliche Flexibilität seiner Bodenfläche in Querrichtung zu erreichen.So that the stabilizer can be attached to the racket handle according to the personal needs of the player regardless of the different widths of the racket grip areas, the intention is further to produce the stabilizer with minimally wide, floor-deep incisions in the longitudinal direction, in order thereby to give the floor area in the transverse direction considerable flexibility to reach.
