Description
Die vorliegende Erfindung betrifft einen Schläger für Ballspiele, insbesondere einen Tennisschläger, Squashschläger, Racquetballschläger oder einen Badmintonschläger, mit einem Rahmen, der einen Kopfbereich zur Aufnahme einer Bespannung und einen Handgriff bzw. Griffabschnitt aufweist. Derartige Schläger können ferner einen zwischen dem Kopfbereich und dem Griffabschnitt angeordneten Herzbereich bzw. eine Gabel aufweisen.The present invention relates to a racket for ball games, in particular a tennis racket, squash rackets, racquetball rackets or badminton rackets, comprising a frame having a head portion for receiving a string and a handle portion. Such clubs may further comprise a heart region or a fork arranged between the head region and the grip section.
Beim Schlagen eines Balles erfolgt zunächst eine Auslenkung des Schlägers durch den Ball. Nach der Auslenkung des Schlägers durch den Ball entfernt sich der Ball vom gebogenen bzw. ausgelenkten Schläger. Der Schläger geht nach der Trennung vom Ball in seine freie gedämpfte Schwingung (Eigenfrequenz) über.When hitting a ball initially takes a deflection of the racket by the ball. After the deflection of the racket by the ball, the ball moves away from the bent or deflected racket. The club goes after the separation from the ball in its free damped oscillation (natural frequency) on.
Beim Schlagen eines Balles wird im Allgemeinen die auf die Bespannung wirkende Kraft über die Bespannung in den Rahmen des Kopfbereichs und von dort über den sich anschließenden Herzbereich in den Griffabschnitt geleitet, wo sie vom Spieler aufgenommen wird. Derartige Kräfte oder Stöße bzw. Schwingungen sind, zumindest in der Langzeitwirkung, dafür mitverantwortlich, dass beim Spieler gesundheitliche Probleme wie beispielsweise der sogenannte Tennisarm auftreten können.When hitting a ball, the force acting on the covering tension is generally passed through the fabric in the frame of the head area and from there over the adjoining heart area in the grip portion where it is absorbed by the player. Such forces or shocks or vibrations are, at least in the long-term effect, partly responsible for the fact that players can experience health problems such as the so-called tennis elbow.
Ferner führt eine andauernde Kompensation des Aufprallschocks und der beim Spiel auftretenden Kräfte zu einer schnellen Ermüdung des Spielers. Auch wird die Kontrolle über den Schläger und damit das Spielverhalten durch zu starke auf den Spieler wirkende Kräfte beeinflußt.Furthermore, a continuous compensation of the impact shock and the forces occurring during the game to a rapid fatigue of the player. Also, the control of the racket and thus the game behavior is influenced by excessive forces acting on the player.
Die

Aus der
Die aus dem Stand der Technik bekannten Schläger erreichen jedoch keine optimale Dämpfung, so dass der beim Ballkontakt entstehende sogenannte Schlagschock bzw. der Aufprallschock bei außermittig getroffenem Ball nur unzureichend abgefangen oder gemildert wird. Der Spieler ist somit beim Spiel hohen Kräften bzw. Impulskräften ausgesetzt, was einerseits die Belastung des Spielers erhöht und andererseits gesundheitliche Folgen, wie z.B. das Entstehen des sogenannten Tennisarms zulässt. Weiterhin hat die Dämpfung des Schlägers bzw. die Frequenz des Gesamtsystems Schläger/Spannung einen wesentlichen Einfluss auf das Führungsverhalten des Schlägers sowie auf das subjektive Spielempfinden des Spielers. Weitere Nachteile des Standes der Technik sind darin zu sehen, dass durch Einschnürungen des Querschnittbereichs des Rahmens potenzielle Schwachstellen geschaffen werden, die bei hohen auftretenden Kräften eine Beschädigung des Schlägers zulassen können. Mit den aus dem Stand der Technik bekannten Schlägern ist weiterhin die Möglichkeit der optimalen, einfachen bzw. schnellen und kostengünstigen Fertigung nicht erfüllt.However, the known from the prior art rackets achieve no optimal damping, so that the resulting when ball contact so-called Shock shock or collision shock in off-center hit ball is insufficiently intercepted or mitigated. The player is thus exposed to high forces or momentum forces during play, which on the one hand increases the load on the player and on the other hand health consequences, such as the emergence of the so-called tennis elbow allows. Furthermore, the attenuation of the racket or the frequency of the overall system racket / tension has a significant impact on the leadership behavior of the racket and the subjective game sense of the player. Further disadvantages of the prior art can be seen in the fact that potential weaknesses are created by constrictions of the cross-sectional area of the frame, which can allow damage to the racket at high forces occurring.
