Description

La présente invention concerne une raquette de tennis de table.The present invention relates to a table tennis racket.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

La plupart des raquettes de tennis de table comportent une palette et un manche dont l'âme est, avec la palette, issue d'une seule plaque en bois découpée selon un contour qui est celui de la palette et du manche. La palette est garnie sur chacune de ses faces d'un revêtement de jeu tandis que le manche est équipé d'une garniture, sensiblement cylindrique, pour former une poignée de préhension de la raquette. Cette poignée vient fusionner avec la palette par une partie qui s'affine en pointe le long de son axe. Elle porte généralement un revêtement favorisant la prise de la raquette.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.

La zone de liaison existant entre la palette et le manche est une zone de concentration de contraintes. En effet, l'impulsion donnée par le joueur lors de chaque coup de jeu se traduit par une accélération importante de la raquette.The 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.

Du fait de l'inertie de la palette dont le centre de gravité est éloigné du manche, l'accélération imprimée se traduit par une déformation de la raquette plus ou moins grande selon que la palette est en matériau plus ou moins souple. Par ailleurs, au moment de l'impact, et selon l'endroit du contact balle/raquette, une contrainte complexe en flexion et torsion est engendrée dans la raquette. La précision du coup s'en ressent. Pour diminuer cet effet déformant, on peut penser raidir la palette en agissant sur la nature et les dimensions du matériau, conduisant à une augmentation du coût ou à une augmentation de la masse de la raquette, ce qui nuit à sa maniabilité et augmente également son inertie.Due to the inertia of the pallet whose center of gravity is remote from the handle, 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.

De plus, la contrainte complexe en torsion autour de l'axe du manche et en flexion perpendiculairement à cet axe, engendrée par cette déformation est importante au niveau de l'emplanture du manche dans la palette. Cette contrainte peut conduire à la rupture de la raquette, si le bois de la palette est de qualité médiocre et, répétée de nombreuses fois, soumet la palette à une fatigue qui peut conduire à sa dégradation.In addition, the complex torsional stress around the axis of the handle and bending perpendicularly to this axis, generated by this deformation is important at the of the root of the handle in the pallet. This constraint can lead to the break of the racket, if the wood of the pallet is of poor quality and, repeated many times, submits the pallet to a fatigue which can lead to its degradation.

Par ailleurs, entre le revêtement et l'âme en bois du manche, le volume de la poignée est donné par des formes en bois ou en matière plastique, rapportée de chaque côté de l'âme. Le décor en surface du manche de la raquette disparaît après un usage prolongé de la raquette et donc une usure intense de la surface du manche.Furthermore, between the coating and the wooden core of the handle, 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.

Il existe de nombreuses raquettes dans lesquelles la garniture rapportée sur le manche déborde sur la base de la palette sans pour autant constituer un renforcement de la liaison manche/palette. On citera à cet effet le document GB 766 106 .There are many rackets in which the lining reported on the handle protrudes on the base of the pallet without constituting a strengthening of the connection sleeve / pallet. For this purpose, the document GB 766 106 .

Il existe donc un besoin d'une structure de manche qui, réponde à un premier objectif, à savoir améliorer la résistance de la raquette au niveau de l'emplanture du manche dans la palette et qui, d'un point de vue esthétique, conserve au manche une qualité durable au cours de l'usage de la raquette.There is therefore a need for a handle structure which meets a first objective, namely to improve the resistance of the racket at the root of the handle in the pallet and which, from an aesthetic point of view, retains at the handle a lasting quality during the use of the racket.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'objet de la présente invention est de satisfaire ce besoin par une structure particulière de manche de raquette.The object of the present invention is to satisfy this need by a particular racquet handle structure.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

A cet effet, l'invention a donc pour objet une raquette de tennis de table comportant une palette et un manche, s'étendant sensiblement radialement depuis le bord de la palette, ce manche ayant une âme centrale issue en une seule pièce de la palette et, de chaque côté de cette âme, une structure rapportée sur l'âme pour donner un volume et une forme extérieure au manche, correspondant à une ergonomie déterminée, la structure rapportée présentant une partie terminale du côté de la palette en forme de trompe évasée, venant recouvrir la zone de la palette immédiatement à proximité de l'emplanture du manche et fixée à cette palette dans laquelle la structure rapportée comporte un noyau central, limité par une face de base pour son collage sur l'âme qui forme une bride de maintien et de centrage pour au moins un capotage en matière plastique enjoliveur du manche qui s'étend partiellement par une partie en forme de trompe évasée et amincie au-dessus de la palette de jeu.For this purpose, 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.

Cette structure permet de lier fermement le manche et la palette par une zone de répartition des contraintes apte à mieux les encaisser et donc augmenter la raideur de la raquette et la nervosité de la réponse en cours de jeu.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.

Le capotage en matière plastique qui s'étend partiellement au-dessus de la palette de jeu au niveau de l'emplanture du manche possède des organes d'encliquetage avec l'autre capotage au travers de la palette. Le noyau central peut être en bois de sorte que sa liaison avec le bois de l'âme est aisément réalisée par collage et ce, de manière résistante. Au plan esthétique, ce noyau comporte une portion de surface extérieure en continuité avec la surface extérieure du capotage.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.

Certains modèles de raquettes, conformes à l'invention, comportent deux coques de capotage en matière plastique qui s'emboîtent l'une dans l'autre et sont maintenues assemblées par le noyau. La matière de l'une des coques sera de préférence de nature à améliorer le toucher et la préhension de la raquette par l'utilisateur (en élastomère par exemple).Some models of snowshoes, according to the invention, 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).

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En se reportant aux quatre premières figures, on voit qu'une raquette selon l'invention comporte une première pièce centrale 1, généralement en bois définissant une palette 1a, représentée très partiellement à la figure 1 et l'âme 1b d'un manche 2.Referring to the first four figures, it is seen that 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.

De chaque côté de l'âme, le manche 2 comporte un assemblage d'éléments constituant son volume. Ces éléments sont, dans le cas de ces figures, au nombre de trois, à savoir une première coque (ou capotage) en matière plastique 3, une seconde coque (ou capotage) en matière plastique 4 et un noyau en bois 5.On each side of the soul, 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.

La première coque 3 est, vue de face, en forme générale d'une ceinture reposant sur le bord de l'âme du manche par un filet (voir les repères 3a et 3b sur les figures 2 et 4) et sur l'emplanture du manche dans la palette 1a par une sorte de trompe évasée 3c. Au niveau de cette trompe, chaque coque 3 est amincie en s'éloignant du manche et possède des moyens 10 et 11, mâle et femelle, d'encliquetage mutuel au travers de la palette 1a, pourvue à cet effet de trous traversants 12. C'est cette partie de coque qui constitue le renfort de la raquette permettant de mieux encaisser les contraintes de flexion subies par la raquette.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. At this horn, 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.

Dans une variante non représentée, la structure de manche peut ne comporter, de chaque côté de l'âme du manche, qu'un seul élément en bois ou en matière plastique, plein on évidé, qui se termine en trompe évasée et aplatie. La fixation de ces deux éléments peut être réalisée sur l'âme du manche par tout moyen approprié : encliquetage en plusieurs endroits traversant des deux parties, collage,... . La fixation des noyaux 5 peut également être réalisée par collage ou par encliquetage transfixiant au travers de l'âme du manche.In a variant not shown, 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.

La ceinture 3, évidée en son centre, reçoit une deuxième coque 4 en matière plastique qui recouvre le bord interne de l'évidement de la première coque. La coque 4 est donc aussi en forme de ceinture dont le contour extérieur coïncide avec le contour intérieur de la coque 3 au niveau duquel, en certains endroits 4a et 4b par exemple, la coque 4 prend appui directement sur l'âme 1b du manche 2. Ce contour extérieur de la coque 4 surplombe partiellement le bord intérieur de la coque 3 et en fait un moyen de son blocage sur l'âme du manche. Le contour intérieur de la coque 4 délimite l'ouverture par laquelle le noyau 5 est apparent à la surface du manche. Le matériau de cette deuxième coque peut être semblable à celui de la première coque. Il sera avantageusement différent comme par exemple un élastomère, vis-à-vis d'un thermoplastique, qui permet d'améliorer la qualité de la préhension.The belt 3, recessed in its center, receives a second shell 4 of plastic material which covers the inner edge of the recess of the first shell. 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.

Ce noyau 5 possède une face inférieure plane 5a qui est collée sur l'âme du manche. Le contour 5b de ce noyau est d'un profil tel qu'il vient en surplomb du bord intérieur de la deuxième coque 4 et constitue le moyen de blocage des deux coques sur l'âme de la raquette lorsqu'il est collé sur l'âme du manche.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.

On comprend qu'avec les moyens décrits, les trois composants principaux du manche sont parfaitement centrés et immobilisés par rapport à l'âme de ce dernier, lorsque le noyau 5 est collé par sa face 5a sur cette âme 1b.It is understood that with the means described, 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.

Le noyau 5 peut comporter en son centre un insert de surface 6 qui peut avoir une fonction décorative ou une fonction sensorielle relative à la qualité du toucher.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.

La nature des matières plastiques et du bois peut également être choisie en fonction de ces critères sensoriels. Les découpes des différentes coques et du noyau permettent aussi une liberté dans l'esthétique du manche. Par ailleurs, les coques peuvent être pleines de sorte que le manche est sans évidements internes. Il peut être intéressant de n'avoir conçu ces coques que comme des peaux de faible épaisseur comme cela est illustré par la partie 3c de la figure 2. Enfin, les dimensions et la précision d'exécution des différents éléments sont telles que leurs surfaces extérieures sont affleurantes et en parfaite continuité les unes avec les autres pour qu'au toucher, on ne sente pas ou peu les lignes de transition qui délimitent les éléments constitutifs du manche.The nature of plastics and wood can also be chosen based on these sensory criteria. The cuts of the different shells and the core also allow a freedom in the aesthetics of the handle. Moreover, the shells can be full so that the handle is without internal recesses. It may be interesting to have designed these hulls only as thin skins as illustrated by part 3c of the figure 2 . Finally, the dimensions and the precision of execution of the various elements are such that their outer surfaces are flush and in perfect continuity with each other so that at touch, we do not feel or little transition lines that delimit the elements constituent of the handle.

A la figure 5, le manche représenté en coupe transversale ne comporte qu'une coque en plastique 13 par côté de l'âme et un noyau en bois 14 collé par sa face 14a sur l'âme 1b du manche 2. Son dessin est donc un peu moins complexe que celui du manche selon les figures précédentes. La coque 13 possède, au niveau de la palette les mêmes moyens d'encliquetage mutuel que ceux 10, 11 décrits ci-dessus.To the figure 5 , 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.
