Definitions

  • the U-shaped profiled hollow profile located in the club head area converges to form a double-T profile in the grip area.
  • a double-T profile can only be mastered with appropriate side shifters, which leads to an increased production outlay and thus to higher costs of this tennis racket.
  • a particularly favorable distribution of the reinforcing ribs results from the subject of claim 2 in that the reinforcing ribs are star-shaped from the
  • OMPI of the club head it being possible to design the counter profile in a different color than the U profile.
  • the counter profile By inserting the counter profile in the interior of the U profile, the string knots are optimally protected.
  • a soft transition at the edges is achieved by the tapered profile legs lying on the end faces of the U-legs, whereby the edges of the hollow profile are themselves protected against damage.
  • the bending resistance moment of the hollow profile in the head region of the racket is reduced compared to the bending resistance moment in the other regions.
  • the tip of the racket head thus has a U-profile of smaller width and lower leg height than comparatively the rest of the U-profile in the other areas of the racket head.
  • FIG. 10 a second variant for forming the reinforcement ribs in a view similar to that in FIG. 2,
  • the support sleeves 7 also form the bores 5 for the string bushings. - Are then appropriate
  • Figure 4 shows that the counter profile can also be formed from a band 20 on which the guide sleeves 7 are integrally formed with the holes 5 made therein.

Abstract

Le cadre pour raquette de tennis se compose d'un profilé creux en U (1, 1a), fabriqué selon un procédé de moulage par injection, ouvert vers l'extérieur dans le plan du cadre, qui est formé d'un pont de liaison (4) et de branches latérales (31, 32) et qui est recouvert de façon emboitée rigide d'un contre-profilé (30); entre les deux profilés (1, 1a; 30), des nervures de renfort (15, 49, 50, 51) et les trous (8) pour les manchons de support (10) recevant les cordes sont liés à l'un des deux profilés (1, 1a; 30) de manière à ne former qu'une seule pièce, les nervures de renfort (15, 49) étant rattachées aux manchons de support (10). Afin d'obtenir une raquette avec une excellente rigidité au gauchissement et très facile à jouer, des nervures de renfort (15, 49, 50, 51) sont rattachées aux manchons de support (10) et sont reliées aussi bien au pont de liaison (4) du profilé creux en U (1, 1a) qu'aux branches latérales (31, 32) dudit profilé creux (1, 1a).
