Definitions

  • the present invention relates to a table tennis racket.
  • Most table tennis rackets have a palette and a handle whose soul is, with the palette, from a single wooden plate cut into an outline that is that of the palette and the handle.
  • the pallet is lined on each of its faces with a game liner while the handle is equipped with a substantially cylindrical lining to form a gripping handle of the racket.
  • This handle merges with the palette by a portion that sharpens in point along its axis. It usually wears a coating promoting the snowshoeing.
  • connection zone between the pallet and the handle is a stress concentration zone. Indeed, the impulse given by the player at each game kick results in a significant acceleration of the racket.
  • the printed acceleration results in a deformation of the racket more or less depending on whether the pallet is more or less flexible material. Moreover, at the moment of impact, and depending on the location of the ball / racket contact, a complex bending and twisting stress is generated in the racket. The precision of the blow is felt. To reduce this deforming effect, we can think of stiffening the palette by acting on the nature and dimensions of the material, leading to an increase in cost or an increase in the mass of the racket, which affects its maneuverability and also increases its inertia.
  • the volume of the handle is given by shapes of wood or plastic, reported on each side of the soul.
  • the surface decoration of the handle of the racket disappears after prolonged use of the racket and therefore an intense wear of the surface of the handle.
  • the object of the present invention is to satisfy this need by a particular racquet handle structure.
  • the invention therefore relates to a table tennis racket comprising a paddle and a handle, extending substantially radially from the edge of the paddle, the handle having a central core in one piece of the pallet and, on each side of this soul, a structure attached to the core to give a volume and a shape outside the handle, corresponding to a determined ergonomics, the reported structure having a part end of the pallet-shaped flaring pallet, coming to cover the area of the pallet immediately near the root of the handle and fixed to the pallet in which the reported structure comprises a central core, limited by a base face for its bonding on the core which forms a holding and centering flange for at least one plastic cap of the sleeve which extends partially by a portion in the shape of a flared and thinened trump above the game board.
  • This structure makes it possible to bind firmly the handle and the pallet by a zone of distribution of the stresses able to better cash them and thus to increase the stiffness of the racket and the nervousness of the answer during game.
  • the plastic cowling partially extending above the game paddle at the root of the handle has latching members with the other cowling through the paddle.
  • the central core may be of wood so that its connection with the wood of the core is easily achieved by gluing and, in a resistant manner. From an aesthetic point of view, this core comprises an outer surface portion in continuity with the outer surface of the cowling.
  • Some models of snowshoes comprise two plastic shrouds that fit into one another and are held together by the core.
  • the material of one of the hulls will preferably be such as to improve the feel and grip of the racket by the user (elastomer for example).
  • a racket according to the invention comprises a first central piece 1, generally made of wood defining a pallet 1a, represented very partially in the figure 1 and the soul 1b of a handle 2.
  • the handle 2 comprises an assembly of elements constituting its volume. These elements are, in the case of these figures, three in number, namely a first shell (or cowl) of plastic material 3, a second shell (or cowl) of plastic material 4 and a wooden core 5.
  • the first shell 3 is, seen from the front, in the general shape of a belt resting on the edge of the soul of the handle by a net (see the marks 3a and 3b on the Figures 2 and 4 ) and on the root of the handle in the pallet 1a by a kind of flared horn 3c.
  • each shell 3 is thinned away from the handle and has means 10 and 11, male and female, mutual snapping through the pallet 1a, provided for this purpose with through holes 12.
  • C is this part of shell which constitutes the reinforcement of the racket making it possible to better cash the flexural stresses undergone by the racket.
  • the handle structure may comprise, on each side of the soul of the handle, only one element made of wood or plastic, solid or hollow, which ends in a flared and flattened horn. Fixing these two elements can be carried out on the soul of the handle by any appropriate means: snap in several places through the two parts, gluing, .... Fixing the cores 5 can also be carried out by gluing or transfixing latching through the core of the handle.
  • the shell 4 is therefore also in the form of a belt whose outer contour coincides with the inner contour of the shell 3 at which, in certain places 4a and 4b for example, the shell 4 bears directly on the core 1b of the handle 2
  • This outer contour of the shell 4 partially overhangs the inner edge of the shell 3 and makes it a means of blocking it on the web of the handle.
  • the inner contour of the shell 4 defines the opening through which the core 5 is apparent on the surface of the handle.
  • the material of this second shell may be similar to that of the first shell. It will advantageously be different as for example an elastomer, vis-à-vis a thermoplastic, which improves the quality of the grip.
  • This core 5 has a flat bottom face 5a which is glued to the core of the handle.
  • the contour 5b of this core is of such a profile that it overhangs the inner edge of the second shell 4 and is the means of locking the two shells on the soul of the racket when it is glued on the soul of the handle.
  • the three main components of the handle are perfectly centered and immobilized relative to the core of the latter, when the core 5 is bonded by its face 5a on the core 1b.
  • the core 5 may comprise at its center an insert of surface 6 which can have a decorative function or a sensory function relating to the quality of the touch.
  • the handle shown in cross section comprises only a plastic shell 13 per side of the core and a wooden core 14 bonded by its face 14a on the core 1b of the handle 2. Its design is a little less complex than that of the handle according to the preceding figures.
  • the shell 13 has at the pallet the same mutual latching means as those 10, 11 described above.
  • the core of the racquet handle according to the invention will preferably be of wood but other materials such as synthetic materials may be suitable if, in particular, they are compatible with a connection resistant to the core of the handle by gluing.
