Definitions

  • the present invention relates to a racket for a game of balls, and more particularly to a padel racket or a beach tennis racket.
  • Padel or beach tennis racquets are generally designed like tennis racquets.
  • a hollow frame of composite material is formed, with a head for delimiting, in a peripheral manner, the striking zone of the racket.
  • a piece of foam possibly with holes for the passage of air, is placed in the head of the racket, and several layers wrap the piece of foam and the frame of the head, in order to maintain all.
  • the hitting surface of the racquet is not equal to the area of the racquet head, due to the different mechanical behavior experienced by the user when he hits a ball near the frame.
  • the document FR 2 908 051 describes a padel racket comprising a head and a handle.
  • the racket head comprises a frame with two striking surfaces and defining an internal chamber, and layers of foamed material, laminated inside the internal chamber and having specific densities making it possible to limit vibrations.
  • a racket is not easily achievable, in particular the frame with its internal chamber, and the subsequent lamination of the foamed layers inside said internal chamber.
  • the connection with the handle of the racket, and more particularly the heart is not detailed, although this is an important area in terms of mechanical stresses.
  • the periphery of the racket in the form of a bead, also results in a reduced hitting zone compared to the surface area of the racket head.
  • the document FR 2 908 051 describes a shock absorbing racquet having a head and a shaft.
  • the head has a frame and a set of shock absorbing layers.
  • the frame has an internal chamber. All A shock absorbing layer is mounted in the internal chamber and has several first shock absorbing layers and at least a second shock absorbing layer which is made of foamed material and laminated in the internal chamber in the frame. Two of the first shock absorbing layers abut against the respective striking surface plates. The density of the first shock absorbing layers is greater than the density of the second shock absorbing layer (s).
  • the first and second shock absorbing layers absorb shock from the impact of the paddleball ball when a paddleball player hits the paddleball ball with the hitting surface plate.
  • the present invention aims to solve the various technical problems mentioned above.
  • the present invention aims to provide a racket, in particular a padel or beach tennis racket, which can be manufactured simply and which has improved comfort compared to current rackets, in particular in terms of vibrations and the size of the hitting zone.
  • a racket for a ball game in particular padel or beach tennis, comprising the features of claim 1.
  • the racket for ball game comprises a head and a handle, in which the head is formed by a deformable core material covered by at least one rigid coating layer.
  • the handle is also formed by a deformable core material covered by at least one rigid coating layer.
  • deformable material is understood to mean a material exhibiting an elastic deformation at the end of which it returns to its initial shape, without residual deformation.
  • the racket according to the invention therefore does not have a hollow peripheral frame, unlike current rackets. Indeed, thanks to the rigid coating layer covering the entire racket, it is possible to obtain mechanical resistance properties comparable to those of current rackets, without requiring a tubular frame. It is thus possible to manufacture a racket more quickly and at a lower cost, while retaining the mechanical properties of current rackets. You also get a lighter racquet.
  • a racket is obtained with homogeneous mechanical properties, and better absorption of vibrations. .
  • the manufacture of the racket is thereby simplified since the head and the handle can be manufactured simultaneously.
  • the deformable core material of the head is identical to that of the handle, possibly with different thicknesses.
  • the homogeneity of the core materials makes it possible to increase the absorption of vibrations and to obtain a homogeneous behavior of the racket.
  • the material of the coating layer of the head is identical to that of the handle.
  • the homogeneity of the materials makes it possible to obtain a homogeneous behavior of the racket.
  • the deformable core material of the head and the deformable core material of the handle form an integral material. The deformable core material can thus be manufactured in a single step, to the shape of the final racket, which simplifies manufacture and lowers costs.
  • the coating layer of the head and the coating layer of the handle form a single coating layer, optionally formed by assembling, for example by crosslinking, several plies of different shapes.
  • the material of the coating layer can also be manufactured in one step, which simplifies the manufacture and lowers the costs.
  • the handle comprises a handle and a connecting portion arranged between the handle and the racket head, and the connecting portion is solid or has a central through opening to allow air to pass.
  • the connecting portion is solid or has a central through opening to allow air to pass. The presence of a through opening decreases the friction of the racket during its use, while a solid connecting portion allows simplified and faster manufacture.
  • the racket may also include a means for reversible fixing of the handle on the connecting portion or of the connecting portion on the head. Thanks to its simplified structure, it is possible to envisage multiple removable handles that can be attached to the rest of the racquet, depending on the size of the user's hand.
  • the deformable core material is chosen from: a foam, cork, an elastomer, latex.
  • the deformable core material is chosen for its elastic properties.
  • the material of the rigid coating layer is chosen from: a composite material, such as glass fibers impregnated in a polymeric matrix, a thermoplastic or thermosetting material, such as polycarbonate or polyethylene.
  • a composite material such as glass fibers impregnated in a polymeric matrix
  • a thermoplastic or thermosetting material such as polycarbonate or polyethylene.
  • Polycarbonate provides a particularly resistant and solid coating.
  • the polycarbonate can be applied in the form of a thermoformed sheet, optionally previously decorated. It is then possible to apply, on the core material, the coating with an integrated decoration, so that the manufacture of the racket no longer requires subsequent decoration and varnishing steps.
  • a method of manufacturing a racket for a ball game, in particular padel or beach tennis, comprising a head and a handle comprising the characteristics of claim 9.
  • a part of deformable core material having the shape of the racket is formed, for example by molding or by cutting and / or machining in a plate, and said part is covered with at least one rigid coating layer.
  • the process is thus particularly simplified and rapid, and easily allows adaptations to be made to obtain the desired mechanical properties for the racquet.
  • the figure 1 schematically illustrates a padel racket 1 according to the invention.
  • racket 1 comprises a racket head 2 forming a striking surface, and a handle 3.
  • the handle 3 is mounted in the extension of the racket head 2, and comprises: a handle 4 and two connecting branches 6, 8 defining a recessed space 10 allowing the passage of air.
  • the racket head 2 has two opposing and substantially parallel hitting surfaces 12, 14 , possibly with air passage holes 16, and an edge 18 peripherally connecting the two hitting surfaces 12, 14.
  • the handle 4 can be connected to the racket head 2 by a solid connection zone.
  • the racket head 2 is formed by a core, of deformable core material, surrounded by a coating layer, of rigid material.
  • the handle 3 is formed by a core, of deformable core material, surrounded by a coating layer, of rigid material.
  • the figure 2 shows, in longitudinal section, the racket 1 according to the figure 1 , according to plan II-II.

  • the core 20 of the racket head and the core 24 of the handle 3 are manufactured with the same material, in one piece.
  • core 20, 24 of racket 1 we will thus speak of core 20, 24 of racket 1, to designate both the core 20 of the head 2 and the core 24 of the handle 3.
  • the coating layer 22 of the racket head 2 and the coating layer 26 of the handle 3 are made from the same material, during the same manufacturing step. We will thus speak of coating layer 22, 26 of the racket 1, to designate both the coating layer 22 of the head 2 and the coating layer 26 of the handle 3.
  • the core 20, 24 of the racket is thus formed in a deformable material capable of absorbing shocks, for example a foamed material, such as poly (ethylene-vinyl acetate) (EVA), poly (chloride of vinyl) (PVC) or polyether urethane (PU), cork, rubber, or latex.

It is in particular possible to use a composite material comprising glass fibers pre-impregnated with a thermosetting resin, and free of carbon fiber.
  • the coating layer 22, 26 of the racquet is formed by applying strips of the composite material, disposed on the exposed surface of the core 20, 24 previously formed. The assembly is then placed in a mold, in particular hot, to carry out the crosslinking of the strips of composite material and thus to obtain the final racket before decoration.
