Definitions
- the invention relates to a racket for ball games, with a grip part and an associated striking part with a striking part, the striking part being rotatable relative to the grip part about the longitudinal axis of the grip part and between the grip part and the striking part limiting such a rotation, elastic deformable damping device is arranged, which has a rubber spring element. It can be a tennis, badminton or similar racket.
- the racket according to the invention does not differ in any way from another racket if the damping device is completely accommodated within the handle part.
- Claims 7 and 8 describe embodiments in order to implement the setting option with simple mechanical means.
- Claim 10 describes an embodiment in which each tendon interacts with two bodies, so that there is a uniform distribution of the load on the body of the spring element when using two tendons.
- the tennis racket shown in FIG. 1 has a handle part 10 and an associated impact part 16, consisting of a frame 12 and a covering serving as the striking surface 14.
- a joint 18 indicates that the grip part 10 is decoupled from the striking part 16 by the two parts being rotatable relative to one another to a limited extent in accordance with the arrows 20 and 22, as is indicated by the dashed line 24 surrounding the frame 12.
- the handle part 10 consists essentially of the handle 26.
- FIG. 3 shows a cross section of the handle 26 shown in FIG. 2.
- the core piece 32 has the shape of a prism.
- the tube section 34 corresponds on the outside in profile to a flat octagon and on the inside has two essentially rectangular, niche-like cavities 40 for receiving 4 rubber-elastic bodies 36.
- the cross section of the elastic rubber bodies 36 corresponds essentially to an isosceles triangle.
- the core piece 32 is hollow in the exemplary embodiment, but it can also be made from a full profile, depending on the material used.
- the arrows 42 and the dashed lines 32a of the core piece 32 indicate the possibility of deflecting the core piece 32 relative to the pipe piece 34.
- the shock wave transmitted to the handle or to the hand or arm is reduced by the energy loss per vibration.
- the energy loss is ideally between 15 and 20%.
- the tennis player has the possibility of adjusting the preload of the spring element 30 ′′ on the adjusting screw 70 according to his needs.
- the rubber-elastic body 36 is more or less biased.
- the two movable prismatic projections 56 serving as tensioning members each have two tensioning surfaces 80, which are at least approximately at a right angle stand to each other and each of which faces a rubber-elastic body 36.

- Raquette selon la revendication 6, caractérisée en ce que le mécanisme de réglage présente un tirant d'ancrage (66) coulissant dans le sens longitudinal dans la pièce centrale (32''), qui se met en prise sur les organes de tension (56) pour la transmission d'un mouvement longitudinal en mouvements transversaux de sens opposé au moyen de surfaces obliques (62).
- Raquette selon la revendication 7, caractérisée en ce que les surfaces obliques sont formées par des fentes obliques (62) de sens opposé disposées dans des pièces de guidage (58) reliées aux organes de tension (56), dans lesquelles le tirant d'ancrage (66) se met en prise au moyen d'un boulon coulissant (64).
- Raquette selon l'une des revendications 7 ou 8, caractérisée en ce que le tirant d'ancrage (66) peut être actionné par un dispositif d'actionnement (70) disposé dans le manche (26) du côté de la face frontale (78).
- Raquette selon l'une ou l'ensemble des revendications 6 à 9, caractérisée en ce que chacun des deux organes de tension (56) présente deux surfaces de tension (80) disposées de préférence au moins approximativement à angle droit l'une par rapport à l'autre, dont chacune fait face à un corps (36).
