Definitions

  • the invention relates to the field of rackets used for the practice of sports requiring the striking of an object, in particular a ball. It therefore particularly targets tennis rackets, squash, badminton, etc.
  • rackets many are those whose frame and handle are made of composite materials with fiber and synthetic resin layering.
  • braids of fibers are arranged around a flexible mandrel, inflatable or heat-deformable, and this fibrous reinforcement is impregnated by injection of resin under pressure.
  • the fiber braids extend over the entire length of the frame and the only structural discontinuities are constituted by possible local reinforcements.
  • the invention overcomes these drawbacks. It relates to a tennis racket or other game, of the aforementioned general type, but the frame of which is constituted, for at least two of its zones (handle and main frame comprising the basket and the two branches), by elements which are follow from one zone to another, but are differentiated both by the nature of the mandrel which constitutes the central core or core of the racket, and by the nature of the fibers of the textile sheets enveloping this mandrel, the connection of the two areas of the frame being made by local overlap of the envelopes of the mandrels.
  • the mandrels of the two branches of the main frame stop in the area of the handle being offset axially with respect to each other, as are also advantageously the corresponding envelopes of the ends of these two branches. Possible pre-bonding end to end of the mandrel elements can facilitate mounting and strengthen the connection of the elements of the frame.
  • a racket frame according to the invention is produced with a lower material cost and an improved strength / weight ratio thanks to the judicious choice of the nature and orientation of the fibers as a function of the mechanical stresses specific to each region of the frame.
  • this racket frame is constituted by a basket 1, two branches 2, a bridge 3 and a handle 4.
  • the assembly 1,2 forms the main frame of the frame.
  • connection between the various areas of the framework is effective. It is, in fact, produced by local overlapping of the windings of fibers from one zone of the frame to the other; -it is so in 13 for the connection of the basket 1 with the branches 2, in 14 for the connection of the bridge 3 with the basket 1 and the branches 2, and at 15 for the connection of the handle 4 with the branches 2.
  • This connection by overlapping and by the subsequent impregnation of resin can, moreover, be completed by a bonding, butt end, mandrels from various parts of the frame.
  • connection between the handle 4 and the branches 2 is ensured by overlapping, over a few centimeters, of the braids 7 by the braids 11.
  • This connection by overlapping the textile plies 7 and 11 and by resin impregnation is advantageously completed by bonding. , end to end, chucks 8 and 12.
