Definitions

  • Ball striking device in particular a tennis or S. quash racket
  • the invention relates to a ball hitting device, in particular a tennis or squash racket, consisting of a shaft with a handle and a head attached to the shaft, the frame of which has a striking surface, in particular.
  • Stringing limited, the latter being formed by longitudinal and transverse strings made of plastic, casing or the like extending approximately parallel to the shaft longitudinal axis and transversely thereto.
  • vibration damping to protect the user, namely tennis or squash players, whereby in this regard more or less complex additional aids, such as the integration of separate shock absorbers in the head frame or shaft, helps. It is also known to dampen the vibrations resulting from the covering directly on the covering by means of vibration dampers attached to the covering. In all cases, however, there are additional design measures that require a corresponding effort and are also only partially effective.
  • the present invention is therefore based on the object to provide a ball striking device of the type mentioned, which due to its basic construction, i. H. without additional measures, is vibration-damped and is also characterized by a construction-related enlarged sweetspot, which is particularly advantageous for so-called slice and top spin shots.
  • the importance of the invention lies in the knowledge that a tennis racket can be compared with a tuning fork, namely in conventional tennis rackets with a symmetrically designed tuning fork, the prongs of which swing equally. These vibrations are transmitted in full over the shaft to the tennis or squash player's arm.
  • the tennis or squash racket designed according to the invention is comparable to a tuning fork, the tines of which vibrate differently, so that overall a damped oscillation occurs, with the result that additional
  • the construction according to the invention does not trigger any additional effort during manufacture, that is, in the
  • the construction according to the invention has the great advantage that the so-called sweet spot in the area of the longest main string is additionally lengthened and enlarged accordingly, so that the playing quality of the racket increases accordingly. This applies especially to so-called slice and topspin strokes. With these stroke variants, the ball strikes in the area of the longest main string, ie in the area of the maximum elasticity of the string, in order to then roll off the string and leave it in the area of a shorter main string, where increased pressure is exerted on the ball.
  • the lateral offset of the longest main string corresponds at least approximately to the distance between two adjacent main strings in the center of the stringing.
  • the lateral offset advantageously corresponds to two to three times the distance between two adjacent long sides in the center of the covering.
  • FIG. 1 shows a tennis racket designed according to the invention in plan view
  • Fig. 2 is the pressure exerted on a ball
  • the tennis racket 10 shown in plan view in FIG. 1 consists of a shaft 12 with a handle 11 and a head attached to the shaft 12, the frame 16 of which delimits a striking surface, namely covering 15, the latter being approximately parallel to the shaft longitudinal axis 19 and across longitudinal strings 22 and cross strings 23 extending therefrom
  • Plastic, intestine or the like is formed.
  • the transition between head frame 16 and shaft 12 is formed by a so-called open heart 13.
  • the head frame 16 is designed asymmetrically relative to the longitudinal axis 19 of the shaft. Specifically, it comprises two frame branches 27, 28 of different lengths such that the longest longitudinal string 20 is laterally offset from the shaft longitudinal axis 19.
  • the lateral offset of the longest longitudinal axis 20 corresponds in the exemplary embodiment shown to approximately 2.5 times the distance between two adjacent longitudinal strings 22 in the central region of the covering 15.
  • the two frame branches 27, 28 can additionally be of different hardness or elasticity. In principle, for vibration damping, it is also conceivable for the two frame branches 27, 28 to be of different hardness in the case of a conventional symmetrical design of the head frame 16. In this case, however, the enlargement or extension of the sweet spot mentioned above, which is identified in FIG. 1 by reference number 18 in comparison to the conventional sweet spot 17, is not obtained.
  • the head frame 16 is formed in one piece in a conventional manner and connected to the shaft 12.
  • the different length of the two frame branches 27, 28 is obtained in the exemplary embodiment shown in that the heart bar 14 is not designed to extend or extend transversely to the longitudinal axis of the shaft, but rather to extend obliquely thereto. The same effect could be achieved by using
  • one of the two frame branches to be indented or bulged out approximately halfway up the head frame 16 with a corresponding shortening or extension thereof.
  • the transverse dimension of the sweet spot is then changed in a similar manner, so that corresponding effects can be achieved when playing the racket.
  • the embodiment shown in FIG. 1 is characterized in that the basic shape of the tennis racket remains essentially unchanged in comparison to conventional tennis rackets.
  • the only change is the inclined position of the heart bridge 14 relative to the shaft axis 19 with a corresponding lateral displacement of the longest longitudinal string 20 relative to the geometric shaft longitudinal axis 19.
  • the sweet spot in the area of the longest longitudinal axis 20 is extended downward (area 18).
  • the ball 21 thus strikes the fabric in the area of maximum elasticity.
  • the tennis racket shown is therefore "out of tune" with regard to its natural vibrations, as a result of which high vibration damping is obtained.
  • the oscillation of the left head frame branch 28, which also includes the heart bridge 14, superimposes the oscillation of the right head frame branch 27 in FIG. 1 such that only a strongly damped overall oscillation remains on the shaft 12. arises, whereby with appropriate dimensioning of the two frame branches 28 on the one hand and 27 on the other hand the total vibration can be almost completely damped.
  • both head frame branches 27, 28 is thus achieved in the illustrated embodiment in that the left head frame branch 28 in FIG. 1 additionally includes the heart bridge 14.
  • the left frame branch 28 is extended, including the heart bridge 14, to the connection to the right frame branch 27.
  • the longitudinal axis of symmetry of the covering 15 is also displaced to the right relative to the geometrical longitudinal axis 19 of the shaft in FIG. 1. It lies approximately in the area of the longest main string 20.

Abstract

Un dispositif de frappe de balle, notamment une raquette de tennis ou de squash (10), possède un manche (12) avec une grippe (11), et un panier fixé sur le manche (12), dont le cadre (16) délimite une surface de frapppe, en particulier un tamis (15) formé de cordes longitudinales (22) et transversales (23) en plastique, boyau, ou similaire, qui s'étendent parallèlement ou transversalement à l'axe longitudinal (19) du manche. Afin de permettre un amortissement des vibrations ainsi qu'un agrandissement assymétrique du point d'efficacité maximum (18), le cadre (16) du panier comporte, par rapport à l'axe longitudinal (19) du manche, deux branches (27, 28) de longueur différente de telle manière que la corde longitudinale la plus longue (20) est latéralement décalée par rapport à l'axe longitudinal géométrique (19) du manche.
