Abstract

The tennis racket is for beginner's use and for training. It has a circular frame (1) which is extended by a short interchangeable handle (2). The handle is joined to the frame by a partly threaded rod (4) that goes through a hole through the handle and is held in place by a nut (6). The top of the rod is encased in the heart (3) of the racket. The rod has a rib (7) near the top and this corresponds to a groove (8) inside the handle to ensure that they are positioned correctly.

Description

La présente invention concerne le sport tennistique et plus particulièrement les raquettes employées pour sa pratique. The present invention relates to tennis sport and more particularly to the rackets used for its practice.

En raison d'un engouement certain pour ce sport et du développement important du nombre de ses pratiquants, on a vu et on voit apparaitre sans cesse des équipements de plus en plus per fectionnés et même souvent exagérément sophistiqués, dont la seule caractéristique notable est d'être d'un prix d'achat élevé. Due to a certain craze for this sport and the significant development of the number of its practitioners, we have seen and we see constantly appearing equipment more and more perfected and even often exaggeratedly sophisticated, the only notable characteristic of which is 'be of a high purchase price.

Ainsi, pour ce qui intéresse les raquettes, l'évolution a -été fortement marquée, à compter des années 60, par l'utilisation des fibres de verre, du carbone, du métal et par la création recente de la raquette à double branche.Thus, for what concerns snowshoes, the evolution has been strongly marked, from the 60s, by the use of glass fibers, carbon, metal and by the recent creation of the double-branched racket.

Cependant que les efforts des fabricants portaient essentiellement sur la recherche de nouveaux matériaux, le plus souvent empruntés à la construction automobile ou aéronautique, peu de solutions etaient proposées au joueur debutant qui se voyait contraint d'utiliser des équipements qui ne correspondaient pas toujours à son niveau technique. While the efforts of the manufacturers focused mainly on the search for new materials, most often borrowed from automobile or aeronautical construction, few solutions were proposed to the beginner player who saw himself forced to use equipment which did not always correspond to his technical level.

Dès lors, des matériels plus adaptés notamment à la morphologie des femmes et des enfants, sont apparus mais ceux-ci ne sont en réalité que des modèles réduits des raquettes du type classique ou des réalisations en matériaux legers de ces dernièrets. Consequently, materials more suited in particular to the morphology of women and children, appeared but these are in reality only reduced models of snowshoes of the classic type or realizations in light materials of these latter.

Peu de solutions ont été imaginées touchant à la géométrie elle-même de la raquette dont les formes n'ont en fait guère evo- lue depuis ses origines. Few solutions have been imagined relating to the geometry of the racket, the shapes of which have in fact hardly changed since its origins.

C'est un des buts de la présente invention que de combler cette lacune et de proposer une raquette conçue essentiellement pour l'initiation au tennis en tenant notamment compte du fait qu'un tel matériel doit pouvoir être adapté en permanence aux progrès réalisés par le pratiquant, ceci afin de lui permettre, au terme de son apprentissage, d'employer les équipements conventionnels avec toutes les possibilités techniques offertes par ceux-ci. It is one of the aims of the present invention to fill this gap and to propose a racket designed essentially for initiation to tennis, taking into account in particular the fact that such equipment must be able to be constantly adapted to the progress made by the player. practicing, this in order to allow him, at the end of his apprenticeship, to use conventional equipment with all the technical possibilities offered by it.

A cette fin, l'invention a pour objet une raquette, remarquable en ce qu'elle est formée d'un cadre rond prolongé d'un manche court de préférence interchangeable. To this end, the invention relates to a racket, remarkable in that it is formed of a round frame extended by a short handle, preferably interchangeable.

Le cadre se distingue ainsi de celui des raquettes du type classique, qui adopte en général la forme d'un ovale allongé. The frame is thus distinguished from that of snowshoes of the classic type, which generally takes the form of an elongated oval.

Cette forme ronde offre, en ce qui concerne la structure proprement dite de la raquette, un certain nombre d'avantages dont le plus évident est une amélioration sensible du coefficient de réponse du cordage qui est formé d'éléments verticaux et horizontaux d'égale longueur, soumis à une tension uniforme. This round shape offers, with regard to the actual structure of the racket, a number of advantages, the most obvious of which is a significant improvement in the response coefficient of the string which is formed of vertical and horizontal elements of equal length. , subjected to a uniform tension.

Il est à noter que la forme ronde du cadre cordé procure ainsi au joueur un meilleur contrôle de sa raquette tout en lui apportant un gain appréciable de puissance. It should be noted that the round shape of the corded frame thus gives the player better control of his racket while providing it with an appreciable gain in power.

Cette plus grande maniabilité est également permise par les dimensions du manche qui est sensiblement plus court que celui des raquettes habituellement utilisées. On se réfere à cet effet à la maniabilité offerte par le manche d'une raquette de tennis de table. This greater maneuverability is also allowed by the dimensions of the handle which is significantly shorter than that of the rackets usually used. We refer to this effect to the maneuverability offered by the handle of a table tennis racket.

Cependant, si un matériel d'une telle conception fournit un confort certain à son utilisateur, le but éducatif pour lequel il a éte essentiellement imaginé n'est pas pour autant négligé. However, if a material of such a design provides a certain comfort to its user, the educational purpose for which it was essentially imagined is not neglected.

Ainsi il a été éprouvé que l'emploi d'un manche court contraignait à des efforts plus importants que lors de l'utilisation d'une raquette de géométrie classique, le travail musculaire ainsi demandé ne pouvant que s'avérer bénéfique pour le débutant et egalement pour le joueur confirmé désirant entretenir ou developper ses moyens physiques. Cependant, le manque de poids en tete procuré par un bras de levier plus court permet de soulager l'effort fourni par le poignet, de maitriser définitivement la prise et de la maintenir plus longtemps. Thus, it has been proven that the use of a short handle requires greater effort than when using a racket of conventional geometry, the muscular work thus requested can only prove to be beneficial for the beginner and also for the confirmed player wishing to maintain or develop his physical means. However, the lack of head weight provided by a shorter lever arm makes it possible to relieve the effort provided by the wrist, to master the grip permanently and to maintain it longer.

D'autre part, l'amovibilité de ce manche permet d'associer au cadre, des manches de sections plus ou moins importantes afin de les ajuster exactement aux dimensions de la main et, surtout, elle permet de modifier à volonté la longueur totale de la raquette afin d'adapter celle-ci à la progression du joueur lors de son apprentissage. En ce sens, on peut considérer que la raquette de l'invention constitue un instrument efficace des méthodes d'initiation évolutives.  On the other hand, the removability of this handle makes it possible to associate with the frame, sleeves of more or less large sections in order to adjust them exactly to the dimensions of the hand and, above all, it allows to modify at will the total length of the racket in order to adapt it to the player's progress during his learning. In this sense, we can consider that the racket of the invention constitutes an effective instrument of evolutionary initiation methods.

Afin d'illustrer et de compléter le présent exposé, on décrit ci-dessous un exemple de réalisation d'une raquette conçue selon les enseignements de l'invention. Cette description faisant référence aux dessins annexés sur lesquels
- la figure 1 est une vue en perspective de cette raquette
- et la figure 2, une vue en élévation de la même raquette dont le cadre et le manche ont été préalablement séparés.
In order to illustrate and complete the present description, an example of embodiment of a racket designed according to the teachings of the invention is described below. This description referring to the attached drawings on which
- Figure 1 is a perspective view of this racket
- And Figure 2, an elevational view of the same racket whose frame and the handle have been previously separated.

Ainsi qu'on peut le voir à la figure 1, la raquette est formée de manière classique, d'un cadre 1 garni d'un réseau de cordes synthétiques ou de boyaux, prolongé par un manche 2 relié au cadre par une partie plane 3 appelée communément "coeur". As can be seen in Figure 1, the racket is conventionally formed of a frame 1 furnished with a network of synthetic strings or hoses, extended by a handle 2 connected to the frame by a flat part 3 commonly called "heart".

En se reportant maintenant à la figure 2, on constate que le cadre 1 est parfaitement rond et que le manche 2, dans la réalisation illustrée, est d'une longueur inférieure environ d'un tiers à celle des manches des raquettes couramment employées. Referring now to Figure 2, we see that the frame 1 is perfectly round and that the handle 2, in the illustrated embodiment, is of a length approximately one third less than that of the handles of snowshoes commonly used.

La liaison entre le cadre et le manche est effectuée au moyen d'une tige 4 filetée à son extrémité et dont la tête- est noyée dans le coeur 3, le manche étant perce d'un conduit longitudinal 5 destine à s'engager autour de la tige 4. Un écrou 6 vient se visser en s'engageant partiellement à l'intérieur du manche 2 sur la partie filetee de la tige 4 pour rendre solidaire l'ensemble cadre 1-manche 2. The connection between the frame and the handle is carried out by means of a rod 4 threaded at its end and the head of which is embedded in the core 3, the handle being pierced with a longitudinal duct 5 intended to engage around the rod 4. A nut 6 is screwed by partially engaging inside the handle 2 on the threaded part of the rod 4 to make the frame 1-handle 2 assembly.

Des moyens de guidage connus, tels une cannelure 7 preformée sur la tige 4 et une rainure 8 correspondante dessinee à l'inte- rieur du manche 2, permettent d'eviter, lors de la liaison cidessus décrite, une mauvaise position du manche 2 par rapport aux parties planes du coeur 3. Known guide means, such as a groove 7 preformed on the rod 4 and a corresponding groove 8 drawn inside the handle 2, make it possible to avoid, during the connection described above, a bad position of the handle 2 by relation to the flat parts of the heart 3.

On observera en dernier lieu, qu'outre les avantages précedemment enoncés, l'amovibilité du manche offre un intérêt pratique non négligeable dans la mesure ou elle permet de réduire l'encombrement de la raquette pour son transport. Finally, it will be observed that, in addition to the advantages previously stated, the removability of the handle offers a practical advantage which is not insignificant insofar as it makes it possible to reduce the size of the racket for its transport.

L'invention venant d'être exposée et son intérêt démontré, le demandeur s'en réserve l'exclusivité sans limitation autre que celle résultant des termes des revendications ci-après anne xées.  The invention having just been exposed and its interest demonstrated, the applicant reserves the exclusivity without limitation other than that resulting from the terms of the claims appended hereafter.
