  • the reason why the shaft 1 is equipped with two bulgings 5, 7 is to make it suitable also for a two hand grip that is practised by many players, preferably in connection with backhanders.
  • the distance between the two bulgings 5, 7, in the longitudinal direction of the racket shaft 1 may of course vary depending on the size of the hands of the player that is gripping the racket shaft 1.

  • the grip portion 13 is equipped with a layer 8, preferably of rigid plastic, and the cross section of this layer 8 is adapted to the cross section of the core 12, i.e. the layer 8 defines an internal hole of the grip portion 13.
  • the rest of the grip portion 13, i.e. the portion having the bulgings 5, 7 and the intermediate portion 9, is preferably made out of silicone rubber or foamed rubber. This is of course only an example and the user may of course choose material in the grip portion in order to achieve an optimum of individual adaption.
  • a knob 11 is attached, said knob 11 having a spherical shape in the portion that faces away from the adjacent second bulging 7.
  • a knob 11 is attached, said knob 11 generally having a maximum across dimension T that is essentially larger than the diameter D of the end of the shaft 1 that the knob 11 adjoins to.

  • This core 12 is rigidly connected to the racket head 3 in such a way that existing forces may be transferred between the racket head 3 and the core 12.
  • the racket shaft 1 also comprises a grip portion 13 that in its turn is equipped with the two bulgings 5 and 7 and the intermediate portion 9.
  • the core 12 has an external out-of-round cross sectional shape and the grip portion 13 has an internal through going hole 8 having the corresponding out-of-round cross sectional shape. The reason therefore is to avoid that the grip portion 13 rotates relative to the core 12.
  • the cross sectional shape is octagonal.
  • the racket shaft 1 also comprises the knob 11 that is equipped with an externally threaded portion 14 and a detachable cap 15 that is located on a diametrically opposite side of the knob 11 relative to the threaded portion 14.
  • the cap 15 is connected to the rest of the knob 11 by means of a thread coupling, the rest of the knob 11 being hollow, see figure 4.
  • Fig 4 it is shown how the components according to figure 3 are assembled in order to create a racket shaft 1 according to the present invention.
  • the grip portion 13 is pushed on the core 12 and the knob 11 is mounted on the free end of the core 12.
  • the detachable mounting of the knob 11 is effected by having the externally threaded portion 14 to cooperate with an internally threaded hole 16 in the core 12.
  • a suitable tightening of the knob 11 effects a proper anchoring of the knob 11 on the free end of the core 12.
  • the hollow knob 11 is filled with lead pellets 17 that gives the possibility to affect the weight distribution of the racket according to the present invention.
  • different sizes of the grip portion 13 it is basically the question of different maximum diameters of the bulgings 5, 7 and also the mutual distance between the bulgings 5, 7.
  • knobs 11 different sizes normally means different across dimensions T.

  • different materials of the grip portion 13 soft silicone-like rubber, more rigid foamed rubber or a combination of different plastics may be mentioned in an exemplifying and non-restricting purpose. It is also possible that the material used for the grip portion 13 is inherently vibration damping or that vibration damping inlays are locally attached between the core 12 and the grip portion 13.
  • the grip portion 13 may also have different surface patterns, e.g. grooving, projecting pimples, recessed holes, wave-like embossing. Taken together, proper choice of material and proper surface pattern gives a compact contact with the hand as well as proper absorption of existing sweat. The material and the surface pattern bring about an airiness that enables cooling of the hand and a natural dryout of excessive sweating of the hand.
  • surface patterns e.g. grooving, projecting pimples, recessed holes, wave-like embossing.
  • both the grip portion 13 and the knob 11 are detachably attached to the core 12.

  • the knob 11 attached to the free end of the core 12, brings about that the hand is given a distinct support at the free end of the shaft portion 1. This brings about a natural prevention against dropping the racket, i.e. it is in principle not possible for the racket to slide out of the hand. Besides the knob 11 increases the contact surface between the shaft portion 1 and the hand of the player.
  • the knob 11 also brings about other functional benefits when using the racket according to the present invention.
  • the player In tennis it is a distinct benefit for the player to have a large reach in his/her motions and to have a high point of impact relative to the court of the opponent. This is especially important in connection with the serve.
  • the knob 11 somewhat increases the length of the racket shaft 1, compared to a conventional racket shaft, since the grip fully or partly may be located to the knob 11. This is of especial importance in connection with the serve and when returning balls close to the sidelines.
  • the internal through going hole of the grip portion 13 and the core 12 have cross sections corresponding to each other.
  • the grip portion 13 is designed from such a flexible material that the internal through going hole of the grip portion 13 adapts to the external shape of the core 12 when the grip portion 13 is mounted on the core 12, this preferably being done by pushing the grip portion 13 on the core 12. Also in this case it is avoided that the grip portion 13 rotates relative to the core 12.
