Abstract

A racquet for playing a ball game constituted by one piece moulded in rigid plastics material, comprises a frame across which extends a grid formed by rigid bars intersecting one another in two directions, and a handle of constant thickness. The width of the handle decreases progressively from the frame to an intermediate zone of smallest width, then increases to the end of the handle, so as to define two opposite side walls in arcuate form, of outwardly facing concavity. A sleeve made of rubber having the same shape as the handle is fitted and held firmly on said handle. The rubber sleeve is maintained in place on the plastics handle, without adhesion, by means of hollow parts provided on the handle and/or on the sleeve and in which engage parts in relief provided on the sleeve and/or on the handle.

Description

La présente invention concerne une raquette pour la pratique d'un jeu de balle.The present invention relates to a racket for playing a ball game.

On connaît déjà divers types de raquettes dont les formes sont adaptées aux jeux et sports dans lesquels elles sont utilisées. Par exemple, les raquettes de tennis comportent un cadre ovale assez allongé prolongé par un manche relativement long pour permettre au joueur, en allongeant le bras, d'atteindre une balle le plus loin possible. Dans le cas du tennis de table, les raquettes utilisées, relativement légères, sont constituées d'une plaque de contreplaqué découpée et recouverte de caoutchouc mousse cette plaque étant prolongée par un manche relativement court.Various types of rackets are already known, the shapes of which are adapted to the games and sports in which they are used. For example, tennis rackets have a fairly elongated oval frame extended by a relatively long handle to allow the player, by extending the arm, to reach a ball as far as possible. In the case of table tennis, the rackets used, which are relatively light, consist of a cut plywood plate covered with foam rubber, this plate being extended by a relatively short handle.

Maigre la grande variété de raquettes connues à ce jour la conception d'une raquette spéciale est devenue nécessaire pour les nouveaux jeux de balle actuellement en voie de développement car toutes les raquettes existantes ne s'adaptent pas à ces nouveaux jeux et empêchent d'atteindre les performances désirées. En effet dans ce nouveau sport qui utilise une balle reliée par un lien non élastique à un poteau reposant ou fixé sur le sol, le joueurindividuel doit donner le plus grand nombre de coups possible sur la balle, dans un tempstrès court et déterminé. De ce fait, la balle étant frappée avec force et revenant avec force, il est nécessaire que le bras de levier de la raquette soit court et que la prise de la main soit asez rapprochée du centre de la raquette où la balle frappe sinon la poignée tourne dans la main et on ne peut pas jouer avec rapidité. Par ailleurs, avec un tel type de jeu, comme il s'agit de développer une force importante dans un temps minimal, il est nécessaire que la prise de la main sur le manche de la raquette soit aussi forte que possible. Par conséquent, toutes les raquettes connues jusqu'à ce jour ne conviennent pas et la présente invention a pour but de fournir une raquette particulièrement adaptée à ce jeu.Despite the great variety of rackets known to date, the design of a special racket has become necessary for the new ball games currently under development because all existing rackets do not adapt to these new games and prevent reaching desired performance. Indeed in this new sport which uses a ball connected by a non-elastic link to a post resting or fixed on the ground, the individual player must give the greatest number of shots possible on the ball, in a short and determined time. Therefore, the ball being struck with force and returning with force, it is necessary that the lever arm of the racket is short and that the grip of the hand is close enough to the center of the racket where the ball hits otherwise the handle spin in the hand and you can't play fast. Furthermore, with such a type of game, since it is a question of developing a significant force in a minimum time, it is necessary that the grip of the hand on the handle of the racket is as strong as possible. Consequently, all the rackets known to date are not suitable and the present invention aims to provide a racket particularly suitable for this game.

A cet effet, cette raquette pour la pratique d'un jeu de balle, constituée d'une seule pièce moulée en manière plastique rigide comprenant un cadre en travers duquel s'étend une grille formée de barrettes rigides se recoupant suivant deux directions, et un manche d'épaisseur constante, est caractérisé en ce que la largeur du manche va progressivement en décroissant à partir du cadre jusqu'à une zone intermédiaire de plus petite largeur puis en croissant jusqu'à l'extrémité du manche, de manière à définir deux parois latérales opposées en forme d'arc à concavité tournée vers l'extérieur, et en ce qu'une poignée en caoutchouc de même forme que le manche est emboîtée et maintenue fermement sur le manche.To this end, this racket for the practice of a ball game, consisting of a single piece molded in rigid plastic manner comprising a frame across which extends a grid formed of rigid bars overlapping in two directions, and a handle of constant thickness, is characterized in that the width of the handle goes gradually decreasing from the frame to an intermediate zone of smaller width then increasing to the end of the handle , so as to define two opposite lateral walls in the shape of an arc with a concavity facing outwards, and in that a rubber handle of the same shape as the handle is fitted and held firmly on the handle.

La raquette suivant l'invention offre l'avantage qu'elle permet d'obtenir une très bonne prise dans la main et que cette raquette est empêchée de tourner même dans le cas de frappes intenses répétées. Par ailleurs, la forme incurvée particulière du manche et de la poignée qui le recouvre empêche que la main ne recule et ne glisse hors de la poignée.The racket according to the invention has the advantage that it makes it possible to obtain a very good grip in the hand and that this racket is prevented from turning even in the case of repeated intense strikes. Furthermore, the particular curved shape of the handle and of the handle which covers it prevents the hand from moving back and slipping out of the handle.

Suivant une caractéristique complémentaire de l'invention la poignée en caoutchouc est maintenue en place sur le manche en matière plastique, sans collage, au moyen de parties en creux prévues sur le manche et/ou sur la poignée et dans lesquelles s'engagent des parties en relief prévues sur la poignée et/ou sur le manche. Ce montage sans collage de la poignée sur le manche évite les inconvénients que l'on rencontre avec les raquettes de tennis, à savoir la possibilité de voir apparaitre des déplacements ou des déchirures de la garniture rapportée sur le manche de la raquette.According to an additional characteristic of the invention, the rubber handle is held in place on the plastic handle, without gluing, by means of hollow parts provided on the handle and / or on the handle and in which parts engage. in relief provided on the handle and / or on the handle. This assembly without gluing of the handle on the handle avoids the drawbacks encountered with tennis rackets, namely the possibility of appearing displacements or tears of the lining attached to the handle of the racket.

On décrira ci-après,à titre d'exemple non limitatif, une forme d'exécution de la présente invention,en référence au dessin annexé sur lequel :

  • La figure 1 est une vue en élévation d'une raquette suivant l'invention.
  • La figure 2 est une vue de profil de la raquette de la figure 1.
  • La figure 3 est une vue en coupe transversale faite suivant la ligne III-III de la figure 1.
  • La figure 4 est une vue en élévation, à plus grande échelle, du manche en matière plastique dépourvu de la poignée en caoutchouc.
  • La figure 5 est une vue en coupe longitudinale de la poignée en caoutchouc séparée du manche en matière plastique.
An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the appended drawing in which:
  • Figure 1 is an elevational view of a racket according to the invention.
  • FIG. 2 is a profile view of the racket of FIG. 1.
  • Figure 3 is a cross-sectional view taken along line III-III of Figure 1.
  • Figure 4 is an elevational view, on a larger scale, of the plastic handle without the rubber handle.
  • Figure 5 is a longitudinal sectional view of the rubber handle separated from the plastic handle.

La raquette suivant l'invention qui est réprésentée dans son ensemble suivant les figures 1 et 2, est constituée d'une seule pièce moulée en matière plastique rigide et comprenant un cadre ovale 1 presque aussi large que haut, c'est-à-dire de forme voisine de celle d'un cercle, une grille 2 s'étendant en travers du cadre 1 et constituée de barrettes de matière plastique rigide se recoupant et s'étendant, parallèlement les unes aux autres suivant deux directions,de préférence perpendiculaires, et un manche 3. Ce manche 3 a une épaisseur constante mais sa largeur varie dans le sens longitudinal. Plus particulièrement, la largeur du manche 3 va en décroissant progressivement à partir d' l'extrémité 3a du manche 3 par laquelle celui-ci se raccorde au cadre 1, pour atteindre un minimum dans une zone intermédiaire 3b à partir de laquelle cette largeur augmente progressivement jusqu'à la paroi extrême 3c du manche qui est de préférence arquée et convexe. La largeur de l'extrémité 3a adjacente au cadre 1 est supérieure à celle de l'extrémité 3c opposée. Le manche 3 est ainsi délimité par deux parois latérales opposées 3d, 3e qui présentent chacune une concavité tournée vers l'extérieur. De préférence, chacune de ces parois 3d et 3e est ondulée, comme on peut mieux le voir sur la figure 4.The racket according to the invention which is shown as a whole according to Figures 1 and 2, consists of a single piece molded in rigid plastic and comprising an oval frame 1 almost as wide as it is high, that is to say similar in shape to that of a circle, a grid 2 extending across the frame 1 and made up of strips of rigid plastic material intersecting and extending, parallel to each other in two directions, preferably perpendicular, and a handle 3. This handle 3 has a constant thickness but its width varies in the longitudinal direction. More particularly, the width of the handle 3 decreases progressively from the end 3a of the handle 3 by which the latter is connected to the frame 1, to reach a minimum in an intermediate zone 3b from which this width increases gradually to the end wall 3c of the handle which is preferably arched and convex. The width of the end 3a adjacent to the frame 1 is greater than that of the opposite end 3c. The handle 3 is thus delimited by two opposite lateral walls 3d, 3e which each have a concavity facing outwards. Preferably, each of these 3d and 3e walls is wavy, as can best be seen in FIG. 4.

Le manche 3 peut présenter avantageusement une section droite en forme de I et qui est constituée d'une âme centrale 3f se raccordant aux deux parois latérales opposées 3d, 3e , lesquelles sont perpendiculaires à l'âme 3f. L'âme 3f est solidaire, dans sa partie médiane, d'une nervure de renforcement longitudinale 3g , perpendiculaire à l'âme 3f et qui s'étend, symétriquement des deux côtés de l'âme 3f, du cadre 1 à la paroi arquée 3c constituant l'extrémité du manche 3.The handle 3 may advantageously have a cross section in the form of an I and which consists of a central core 3f connecting to the two opposite lateral walls 3d, 3e, which are perpendicular to the core 3f. The core 3f is integral, in its middle part, with a longitudinal reinforcing rib 3g, perpendicular to the core 3f and which extends, symmetrically on both sides of the core 3f, from the frame 1 to the arched wall 3c constituting the end of the handle 3.

Le manche 3 peut également comporter d'autres nervures de renforcement auxiliaires perpendiculaires à l'âme 3f et disposées, de chaque côté de cette âme, entre la nervure longitudinale médiane 3g et les parois latérales 3d, 3e. Dans la forme d'exécution non limitative représentée sur le dessin, le manche 3 comporte, de chaque côté de l'âme 3f, deux nervures auxiliaires 3h partant du cadre 1 et s'étendant, suivant une allure arquée,en direction de la zone intermédiaire 3b du manche, entre la nervure médiane 3g et les parois latérales 3d, 3e. De la même façon, deux autres nervures de renforcement 3i s'étendent à partir de la paroi extrême 3c sur une certaine longueur en direction de la zone intermédiaire 3b du manche.The handle 3 may also include other auxiliary reinforcing ribs perpendicular to the core 3f and arranged, on each side of this core, between the longitudinal longitudinal rib 3g and the lateral walls 3d, 3e. In the nonlimiting embodiment shown in the drawing, the handle 3 comprises, on each side of the core 3f, two auxiliary ribs 3h starting from the frame 1 and extending, in an arcuate shape, in the direction of the zone intermediate 3b of the handle, between the middle rib 3g and the side walls 3d, 3e. Similarly, two other reinforcing ribs 3i extend from the end wall 3c over a certain length in the direction of the intermediate zone 3b of the handle.

Le manche 3 présente ainsi, dans son ensemble, une forme symétrique par rapport à deux plans perpendiculaires à savoir le plan de l'âme 3f et le plan de la nervure centrale 3g.The handle 3 thus has, as a whole, a symmetrical shape with respect to two perpendicular planes, namely the plane of the core 3f and the plane of the central rib 3g.

Pour parfaire la tenue de la raquette dans la main, le manche 3 en matière plastique rigide est coiffé d'une poignée 4 en caoutchouc, qui présente la même forme que le manche 3. Autrement dit, cette poignée 4 qui est creuse, est constituée de deux parois planes supérieure 4a et inférieure 4b et de deux parois latérales 4c , 4d perpendiculaires aux précédentes. Les parois latérales 4c , 4d de la poignée 4 présentent la même forme arquée que les parois latérales 3d, 3e du manche. Les quatre parois précitées 4a, 4b, 4c, 4d sont attenantes à une paroi extrême 4e qui est arquée et qui présente le même rayon de courbure que celui de la paroi extrême 3c du manche 3 afin de pouvoir venir se plaquer contre cette dernière. A l'opposé de la paroi extrême 4e, les quatre parois de la poignée 4 délimitent une ouverture permettant d'enfiler cette poignée 4 sur le manche 3.To perfect the grip of the racket in the hand, the handle 3 of rigid plastic material is capped with a rubber handle 4, which has the same shape as the handle 3. In other words, this handle 4 which is hollow, is made up two planar upper 4a and lower 4b walls and two side walls 4c, 4d perpendicular to the previous ones. The side walls 4c, 4d of the handle 4 have the same arcuate shape as the side walls 3d, 3e of the handle. The aforementioned four walls 4a, 4b, 4c, 4d are adjacent to an end wall 4e which is arched and which has the same radius of curvature as that of the end wall 3c of the handle 3 in order to be able to come to be pressed against the latter. Opposite the extreme wall 4e, the four walls of the handle 4 delimit an opening making it possible to thread this handle 4 onto the handle 3.

Une fois la poignée 4 enfilée sur le manche 3, grâce à son élasticité, elle est maintenue fermement en place par suite de l'engagement de parties en saillies prévues sur le manche 3 (ou la poignée 4) dans des parties en creux prévues sur la poignée 4 (ou le manche 3).Once the handle 4 is threaded onto the handle 3, thanks to its elasticity, it is held firmly in place as a result of the engagement of projecting parts provided on the handle 3 (or the handle 4) in hollow parts provided on handle 4 (or handle 3).

On voit par exemple sur le dessin que les deux parois supérieure 4a et inférieure 4b de la poignée 4 présentent chacune, sur leur face interne, une rainure 4g s'étendant longitudinalement dans le plan médian de symétrie et dans laquelle vient s'engager l'extrémité de la nervure longitudinale centrale 3g du manche 3. Par ailleurs, dans la zone proche de l'extrémité ouverte de la poignée 4, chacune de ces parois supérieure 4a et inférieure 4b présente également des parties en creux 4h, disposées symétriquement de part et d'autre de la rainure longitudinale centrale 4g et dans lesquelles viennent s'engager, le long des bords de ces parties en creux 4h, les nervures de renforcement auxiliaires 3h du manche 3.We see for example in the drawing that the two upper 4a and lower 4b walls of the handle 4 each have, on their internal face, a groove 4g extending longitudinally in the median plane of symmetry and into which the end of the central longitudinal rib 3g of the handle 3 engages. Furthermore, in the region close to the open end of the handle 4, each of these upper 4a and lower 4b walls also has parts in hollows 4h, arranged symmetrically on either side of the central longitudinal groove 4g and into which engage, along the edges of these hollow parts 4h, the auxiliary reinforcement ribs 3h of the handle 3.

Les parois supérieure 4a et inférieure 4b de le poignée 4 présentent également, sur leurs faces internes, des bossages 4i voisins de l'extrémité ouverte et de la paroi extrême 4e, ces bossages 4i venant s'engager dans les espaces délimités entre les parois latérales arquées 3d, 3e et les nervures de renforcement auxiliaires 3h du manche 3. Ces bossages 4i contribuent , conjointement avec les rainures 4g, à maintenir fermement en place la poignée rapportée 4 en caoutchouc sur le manche 3 en matière plastique rigide.The upper 4a and lower 4b walls of the handle 4 also have, on their internal faces, bosses 4i close to the open end and to the end wall 4e, these bosses 4i coming to engage in the spaces delimited between the side walls arched 3d, 3e and the auxiliary reinforcement ribs 3h of the handle 3.
