  • F 2 parallel to the longitudinal axis C of the handle.
  • gripping a handle portion with a constant cross-section only a force component which is formed perpendicular to the longitudinal axis of the handle, but no force component, which is parallel to the longitudinal axis of the handle formed.
  • the inventive design of a handle causes the emergence of a force component F 2 , which extends substantially parallel to the longitudinal axis C of the handle. This force component is directed against the gripping surface formed inclined by the widening cross section of the handle and thus enables a secure holding of the handle, since it counteracts slipping out of the grip by the hand of the player.
  • the inventive design of the handle allows both the formation of a frictional connection and the formation of a positive connection between the hand of the player and the handle, whereby a particularly safe, solid and power-saving grip (gripping) of the racket or the handle is possible.
  • a comfortable and safe ambidextrous guiding a racket means a handle according to the invention by a safe and comfortable gripping by the first hand or play hand substantially in the area B of the handle, as described above, the second hand can grip the handle in the section A with a substantially constant cross-section without, for example Disadvantages due to a too small handle diameter, as would occur, for example, in a continuous conical handle occur.
  • the handle according to the present invention offers the advantage that not only an individually optimal gripping of the grip by the player, but also an optimal individual embracing is made possible, as it is often required in the course of a ball game.
  • section B with an expanding cross-section ensures an optimized force and shock introduction into the human body.
  • FIG. 8 The particularly advantageous combination of the grip band according to the invention with the handle according to the invention is shown in FIG. Again, the contours in the plan view of a handle according to the invention with a grip band according to the invention in their extension towards each other and are thus optimally adapted to the contour or anatomy of the human hand and in particular the alignment of the fingers of the human hand.
  • the angle ⁇ i takes between the longitudinal axis of the handle and the longitudinal axis of the grip tape of each winding in the plan view, starting from the handle end (in Fig. Left) towards the head portion (in Fig.
  • the advantages of the handle according to the invention and the grip band according to the invention are effective thus synergistically together.
