Definitions

  • the present invention relates to a racket frame, a racket provided with such a frame, as well as a set of several of these frames.
  • the invention relates more particularly to a racket provided a sieve, such as a tennis racket, badminton racket or squash.
  • the two tubes interiors are arranged side by side, so that their adjacent walls form a transverse rib, intended reinforce the frame, while the presence of the outer tube reduces stresses that may occur at this rib.
  • the invention proposes to produce a racket frame constituting an alternative to the prior art presented above.
  • a racket frame including tennis, squash or badminton, including a tubular body, characterized in that said tubular body has at least one intermediate portion in the vicinity of which are provided with reinforcing means, these means reinforcement defining, with this intermediate portion, a spacer volume extending over the entire periphery outside of said intermediate portion.
  • the invention also relates to a racket, including tennis, squash or badminton, including a frame with a sieve and a rope stretched around of this sieve, characterized in that this frame is as defined above.
  • the invention finally relates to a set of frames, comprising several types of frames as defined above.
  • the racket illustrated in Figure 1 which is designated as a whole by the reference 2, includes a handle 4, surrounded by a covering strip 6, also called “grip”.
  • This handle is extended by a sieve 8, of oval shape, with the interior of which a rope is stretched 10.
  • the area of junction between the handle and the sieve, also called core 12 comprises two divergent branches 14, connected by a bridge 16 at their end opposite to the handle 4.
  • the handle 4, the screen 8 and the heart 12, which form the racket frame, have a rigid tubular body 18 illustrated in particular in Figure 2, which is for example made made of aluminum or more advantageously of composite material.
  • This tubular body could for example be made from carbon fibers which can also be mixed with other types of fibers, such as glass fibers, all these fibers being linked in a matrix which can be a thermosetting or thermoplastic resin.
  • a matrix in epoxy resin may for example be advantageously used.
  • This tubular body 18 has a main portion 20 of substantially constant section, as well as a portion intermediate 22, forming a constriction.
  • the latter which is coaxial with the main portion 20, has a dimension transverse lower than this and is connected to it by via two peripheral shoulders 24.
  • this portion intermediate 22 is present on one of the branches 14 of the heart 12. Alternatively, it can equip another frame region. It is also possible to envisage several similar intermediate portions.
  • a reinforcing element 26 tubular in shape, covers the intermediate portion 22. A this effect, this element 26 extends between the regions of the main portion 20 adjacent to the shoulders 24.
  • This element 26 is made for example of metal, material plastic or, preferably, a composite material. He is by elsewhere coaxial with the main portion 20, as well as with the intermediate portion 22. It is fixed on the regions above of the main portion 20, rigidly.
  • the internal wall of the reinforcing element 26 thus forms, with the external wall opposite the intermediate portion 22, an intermediate volume 28, of annular shape, extending over the whole of the periphery of this intermediate portion 22.
  • This intermediate volume 28 has a longitudinal dimension, or length l , comprised, for example, between 2 and 10 cm, as well as a transverse dimension, or thickness e , comprised, for example, between 0.5 and 5 mm. It is filled by means of a gas, which can in particular be air.
  • FIG. 4 illustrates a first alternative embodiment of the invention, in which the mechanical elements analogous to those of FIGS. 1 and 2 are assigned the same reference numbers, increased by 50.
  • the tubular element 26 is replaced by several rods 76, which extend around the periphery of the intermediate portion 72.
  • FIG. 5 illustrates a second alternative embodiment of the invention, in which the mechanical elements analogous to those of FIGS. 1 and 2 are assigned the same reference numbers, increased by 100.
  • the tubular element 26 is replaced by several bands 126, forming arcs of a circle, which extend to the outer periphery of the intermediate portion 122.
  • FIGS. 1 and 2 illustrates an additional variant of the invention, in which similar mechanical elements to those of FIGS. 1 and 2 are assigned the same numbers of reference, increased by 150.
  • the reinforcing element 176 is rigidly fixed, only at one end, on the main portion 170. On the other hand, it is linked to this last, at its other end, with the interposition of a deformable ring 180.
  • This ring allows a degree of freedom, along the axis main A, between main portion 170 and the element of reinforcement 176.
  • This ring can for example be glued at once to this portion 170 and to this element 176, so it's subject to some shearing, during their mutual displacement along axis A.
  • this ring may not be glued but simply to be interposed between position 170 and the reinforcing element 176, so that it is able to rub along these, during their mutual displacement.
  • the intermediate volume 178 is filled with a foam 182, which is for example of the EVA (ethylene-vinyl-acetate) type.
  • foam 182 can be replaced by any other material which does not significantly influence the mechanical behavior of the whole racket. he can these include, among other things, gel.
  • This intermediate volume is neutral with regard to behavior racket mechanics, insofar as it does not constitute not a structural element of the latter. It indeed forms a bifurcation between the intermediate portion of the body main and reinforcing means, and contributes to them mechanically separate. This volume does not contradict the operation of the racket, especially with regard to relates to deflection and shear.
  • this intermediate portion may have a substantially transverse dimension analogous to that of this main portion.
  • this intermediate portion is then surrounded by a larger diameter reinforcement area, which can be produced as a tubular element or as elements discrete, as in Figures 3 to 5.
  • reinforcing means extending to the periphery of an intermediate portion of the tubular body, belonging to the racket frame, is advantageous. Indeed, these reinforcing means make it possible to increase the rigidity of the racket according to the invention.
  • deformable means modulates the rigidity given to this racket. Of so it is possible to create a range of snowshoes having various rigidities, depending in particular on the user needs.
