Description

La présente invention concerne un embout pour manche de raquette de tennis et autres similaires, et raquette équipée de cet embout, et qui est destiné à être appliqué contre l'extrémité libre de ce manche ou à en constituer éventuellement l'organe de fermeture si ce manche est tubulaire.The present invention relates to a tip for the handle of a tennis racket and the like, and racket equipped with this tip, and which is intended to be applied against the free end of this handle or possibly to constitute the closing member if this handle is tubular.

Il est connu que la prise de raquette, c'est-à-dire la position angulaire du manche dans la main d'un joueur de tennis ou autre, est déterminée par la nature du coup que ce joueur s'apprête à exécuter, tel que coup droit, plat, coupé, ou lifté, revers plat, coupe ou lifté, service et smash.It is known that the racket grip, that is to say the angular position of the handle in the hand of a tennis player or the like, is determined by the nature of the stroke that this player is preparing to execute, such as that forehand, flat, cut, or lifted, flat back, cut or lifted, service and smash.

Au cours de son apprentissage et malgré la forme octogonale, régulière ou non, de la section transversale des manches de raquettes, il est difficile, notamment pour un joueur débutant, de repérer et par conséquent d'adopter la bonne prise avant chacun de ses coups.During his training and despite the octagonal shape, regular or not, of the cross section of the racket sleeves, it is difficult, especially for a beginner player, to identify and therefore to adopt the right grip before each of his shots .

Il est connu, notamment par le document US-A 1 917 236, de recouvrir le manche de la raquette de signes permettant au joueur de repérer les bonnes prises de raquette correspondant aux différents coups à exécuter. Malheureusement, en raison de leur emplacement, ces signes sont soit rapidement effacés par l'usage, soit totalement supprimés au changement de gripp, c'est-à-dire au changement du ruban qui habille généralement les manches de raquettes.It is known, in particular from document US-A 1 917 236, to cover the handle of the racket with signs allowing the player to identify the correct racket grips corresponding to the different strokes to be executed. Unfortunately, due to their location, these signs are either quickly erased by use, or completely deleted when the flu changes, that is to say when the ribbon which generally covers the racket sleeves is changed.

La présente invention vise à remédier à cet inconvénient, en fournissant des moyens permettant un repérage facile de la bonne prise de raquette.The present invention aims to remedy this drawback, by providing means allowing easy identification of the correct grip of the racket.

A cet effet, l'embout qu'elle concerne est constitué au moins par un élément plat, dont le périmètre octogonal correspond sensiblement à celui de la section transversale de l'extrémité libre d'un manche de raquette et qui comporte au moins deux secteurs triangulaires différenciés adjacents, dont un sommet coïncide avec l'axe longitudinal du manche considéré et dont le côté opposé à ce sommet est constitué par l'un des côtés adjacents de son périmètre octogonal, cet élément étant destiné à être fixé à l'extrémité libre du manche, dans une position angulaire déterminée, la différenciation des secteurs triangulaires permettant un positionnement angulaire correct du manche, par rapport à un point précis de la main du joueur.To this end, the endpiece which it relates to is constituted at least by a flat element, the octagonal perimeter of which corresponds substantially to that of the cross section of the free end of a racket handle and which comprises at least two sectors adjacent differentiated triangulars, one apex of which coincides with the longitudinal axis of the handle in question and the side opposite to this apex consists of one of the adjacent sides of its octagonal perimeter, this element being intended to be fixed to the free end of the handle, in a determined angular position, the differentiation of the triangular sectors allowing correct angular positioning of the handle, relative to a precise point in the player's hand.

II suffit ensuite d'indiquer au joueur la position que doit occuper, pour chaque coup envisagé, l'un de ces secteurs par rapport à un point précis de sa main qui tient la raquette, pour qu'il adopte rapidement et sans difficulté, la bonne prise de raquette.It then suffices to indicate to the player the position which one of these sectors must occupy, for each stroke envisaged, with respect to a precise point of his hand which holds the racket, so that he adopts quickly and without difficulty, the good racket grip.

Par exemple, si le point précis de la main à considérer est l'éminence hypothénar, l'embout est fixé à l'extrémité libre du manche, de manière que les secteurs triangulaires différenciés soient disposés en conséquence par rapport au plan médian du cadre de la raquette, c'est-à-dire de son tamis, de telle sorte que chacun d'eux correspond à la zone du manche qui doit être recouverte par l'éminence hypothénar de la main du joueur, pour l'exécution d'un coup déterminé.For example, if the precise point of the hand to be considered is the hypothenar eminence, the endpiece is fixed to the free end of the handle, so that the differentiated triangular sectors are arranged accordingly with respect to the median plane of the frame. the racket, that is to say its sieve, so that each of them corresponds to the area of the handle which must be covered by the eminence hypothénar of the hand of the player, for the execution of a determined move.

On conçoit aisément que cet embout facilite considérablement l'apprentissage des jeux ayant recours à l'utilisation d'une raquette.It is easily understood that this tip considerably facilitates the learning of games using the use of a racket.

L'élément plat peut être constitué simplement par un film auto-collant, ou par une plaquette rigide fixée, de n'importe quelle manière appropriée, à l'extrémité libre du manche, ou encore constituant l'organe de fermeture du manche lorsque ce dernier est tubulaire.The flat element can be constituted simply by a self-adhesive film, or by a rigid plate fixed, in any suitable manner, to the free end of the handle, or even constituting the closing member of the handle when this the latter is tubular.

Suivant une forme d'exécution simple de l'invention, chacun des secteurs triangulaires de l'embout possède une couleur propre qui le différencie des autres.According to a simple embodiment of the invention, each of the triangular sectors of the nozzle has its own color which differentiates it from the others.

Dans le cas où l'embout du manche de raquette est constitué par un cabochon emboîtable sûr l'extrémité libre du manche, c'est-à-dire dans le cas où l'élément plat de l'embout est bordé par une virole cylindrique apte à épouser, en le serrant, le périmètre de l'extrémité libre du manche, chaque secteur triangulaire porté par l'élément plat de l'embout est prolongé, sur la face externe de sa virole, par un secteur cylindrique dont la caractéristique distinctive, couleur ou autre, est la même.In the case where the end of the racket handle is constituted by a nestable cap on the free end of the handle, that is to say in the case where the flat element of the end is bordered by a cylindrical ferrule able to fit, by tightening, the perimeter of the free end of the handle, each triangular sector carried by the flat element of the endpiece is extended, on the external face of its ferrule, by a cylindrical sector whose distinctive characteristic , color or whatever, is the same.

Suivant une autre caractéristique de l'invention, pour permettre au joueur de faire pivoter son manche de raquette de 180° sans perdre l'avantage des repères sectoriels, il est prévu deux jeux de secteurs triangulaires et cylindriques sur l'embout, le second jeu étant disposé symétriquement au premier, par rapport à l'axe du manche.According to another characteristic of the invention, to allow the player to rotate his racket handle by 180 ° without losing the advantage of sectoral marks, two sets of triangular and cylindrical sectors are provided on the end piece, the second set being arranged symmetrically to the first, relative to the axis of the handle.

De toute façon, l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non-limitatif, une forme d'exécution de cet embout et son mode d'utilisation:

  • Figure 1 est une vue en perspective de l'extrémité libre d'un manche de raquette de tennis équipé de cet embout;
  • Figures 2, 3 et 4 sont des vues par derrière de cette raquette de tennis, tenue par un joueur de tennis droitier, illustrant trois prises de raquettes différentes correspondant, respectivement, à un coup droit, à un service, à un revers normal ou à un smash, et à un revers lifté ;
  • Figure 5 est une vue en perspective de l'extrémité libre d'un manche de raquette équipé d'un embout résultant d'une variante d'exécution de l'invention ;
  • Figure 6 est une vue similaire à figure à figure 2 illustrant un mode d'utilisation de la raquette, suplé- mentaire de ceux illustrés par les figures 2 à 4 ;
  • Figure 7 est une vue similaire à figure 1 montrant une autre variante d'exécution de l'embout de l'invention.
In any case, the invention will be clearly understood, with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of non-limiting example, an embodiment of this endpiece and its mode of 'use:
  • Figure 1 is a perspective view of the free end of a tennis racket handle fitted with this tip;
  • Figures 2, 3 and 4 are views from behind of this tennis racket, held by a right-handed tennis player, illustrating three different racket grips corresponding, respectively, to a forehand, a serve, a normal backhand or a smash, and a lifted back
  • Figure 5 is a perspective view of the free end of a racket handle equipped with a tip resulting from an alternative embodiment of the invention;
  • Figure 6 is a view similar to Figure to Figure 2 illustrating a mode of use of the racket, additional to those illustrated in Figures 2 to 4;
  • Figure 7 is a view similar to Figure 1 showing another alternative embodiment of the tip of the invention.

Comme le montre la figure 1, l'embout 2 selon l'invention est constitué par un élément plat sous forme de film, feuille ou plaquette, dont le périmètre est adapté à celui de la section transversale de l'extrémité libre du manche 3 d'une raquette. Ce périmètre est donc octogonal.As shown in FIG. 1, the end piece 2 according to the invention consists of a flat element in the form of a film, sheet or plate, the perimeter of which is adapted to that of the cross section of the free end of the handle 3 d 'a racket. This perimeter is therefore octagonal.

Cet embout 2 est destiné à être fixé, par n'importe quel moyen approprié, contre l'extrémité libre du manche 3 de la raquette, ou il peut aussi bien constituer l'organe de fermeture de ce manche lorsque celui-ci est tubulaire, ce qui se rencontre fréquem- ment.This tip 2 is intended to be fixed, by any suitable means, against the free end of the handle 3 of the racket, or it can as well be consti kill the closing member of this handle when it is tubular, which is frequently encountered.

Cet embout 2 présente trois secteurs triangulaires différenciés 4, 5 et 6. Chaque secteur triangulaire possède un sommet 7 coïncidant avec l'axe longitudinal 3a du manche 3, tandis que le côté opposé à ce sommet 7 de chacun des secteurs triangulaires 4, 5 et 6 est constitué par l'un de trois côtés adjacents 4a, 5a et 6a du périmètre octagonal de l'embout 2.This nozzle 2 has three differentiated triangular sectors 4, 5 and 6. Each triangular sector has a vertex 7 coinciding with the longitudinal axis 3a of the handle 3, while the side opposite this vertex 7 of each of the triangular sectors 4, 5 and 6 is constituted by one of three adjacent sides 4a, 5a and 6a of the octagonal perimeter of the end piece 2.

Chaque secteur triangulaire 4, 5, 6 est destiné à désigner la zone du manche 3 qui doit être recouverte par l'éminence hypothénar de la main 8 du joueur. Sur les figures 2 à 4, cette éminence hypothénar est repérée par la flèche 9.Each triangular sector 4, 5, 6 is intended to designate the area of the handle 3 which must be covered by the eminence hypothénar of the hand 8 of the player. In Figures 2 to 4, this eminence hypothénar is identified by arrow 9.

La différenciation entre les différents secteurs triangulaires 4, 5 et 6 peut être réalisée de n'importe quelle manière appropriée et notamment par des colorations différentes. Il sera donc facile au joueur débutant de saisir le manche 3 de sa raquette avec la bonne position angulaire, c'est-à-dire d'adopter une bonne prise de raquette ; il suffira pour cela qu'il sache quelle zone, correspondant à l'un des trois secteurs triangulaires 4, 5 et 6, doit être couverte par son éminence hypothénar 9 pour chacun des coups qu'il et susceptible de réaliser.The differentiation between the different triangular sectors 4, 5 and 6 can be carried out in any suitable manner and in particular by different coloring. It will therefore be easy for the beginner player to grasp the handle 3 of his racket with the correct angular position, that is to say to adopt a good grip on the racket; it will suffice for this that he knows which zone, corresponding to one of the three triangular sectors 4, 5 and 6, must be covered by his eminence hypothénar 9 for each of the strokes which he and likely to carry out.

En conséquence, pour adopter une bonne prise de raquette, il suffira au joueur de savoir :

  • - que pour exécuter un coup droit, il doit tenir le manche 3 de sa raquette de manière que son éminence hypothénar recouvre la zone de son manche correspondant au secteur triangulaire 4, comme illustré sur la figure 2,
  • - que pour exécuter un service, un revers normal ou un smash, son éminence hypothénar 9 doit recouvrir la zone du manche 3 correspondant au secteur triangulaire 5, comme illustré sur la figure 3,
  • - et qu'enfin, pour exécuter un revers lifté, il doit tenir le manche 3 de manière que son éminence hypothénar 9 recouvre la zone de son manche 3 correspondant au secteur triangulaire 6, comme illustré sur la figure 4.
Consequently, to adopt a good grip of racket, it will be enough for the player to know:
  • - that to execute a forehand, he must hold the handle 3 of his racket so that his eminence hypothénar covers the area of his handle corresponding to the triangular sector 4, as illustrated in FIG. 2,
  • - that to execute a service, a normal backhand or a smash, its eminence hypothénar 9 must cover the area of the handle 3 corresponding to the triangular sector 5, as illustrated in FIG. 3,
  • - And finally, to execute a lifted backhand, it must hold the handle 3 so that its eminence hypothénar 9 covers the area of its handle 3 corresponding to the triangular sector 6, as illustrated in FIG. 4.

Naturellement, l'embout 2 doit être fixé à l'extrémité libre du manche 3 de la raquette avec une position angulaire prédéterminée par le point de référence prescrit de la main du joueur. Dans l'exemple précité, où ce point de référence, est l'éminence hypothénar, l'embout 2 doit être positionné angulai- rement de manière que les trois secteurs triangulaires 4, 5 et 6 soient disposés symétriquement par rapport au plan médian 11 du cadre 12 de la raquette, qui est aussi le plan de son tamis. Ce positionnement correct est évidemment celui montré par les figures 2 à 4 du dessin.Naturally, the tip 2 must be fixed to the free end of the handle 3 of the racket with an angular position predetermined by the prescribed reference point of the player's hand. In the above example, where this reference point is the hypothenar eminence, the end piece 2 must be positioned angularly so that the three triangular sectors 4, 5 and 6 are arranged symmetrically with respect to the median plane 11 of the frame 12 of the racket, which is also the plane of its sieve. This correct positioning is obviously that shown in Figures 2 to 4 of the drawing.

Cet embout 2 peut être réalisé de différentes manières selon qu'il constitue un accessoire adaptable à une raquette, ou qu'il lui est associé dès la fabrication du manche. En effet, il peut se présenter tout simplement comme un film autocollant appliqué à l'extrémité libre du manche 3 d'une raquette, ou encore comme une plaquette rigide en matière plastique ou similaire, équipée de moyens permettant sa fixation à l'extrémité libre du manche 3 d'une raquette. Il peut aussi, comme indiqué précédemment, constituer l'organe de fermeture d'un manche 3 de raquette lorsque celui-ci est tubulaire.This tip 2 can be produced in different ways depending on whether it constitutes an accessory adaptable to a racket, or whether it is associated therewith from the manufacture of the handle. Indeed, it can be presented quite simply as a self-adhesive film applied to the free end of the handle 3 of a racket, or even as a rigid plate made of plastic or the like, equipped with means allowing its fixing to the free end. of handle 3 of a racket. It can also, as indicated above, constitute the closing member of a racket handle 3 when the latter is tubular.

Cet embout peut aussi être constitué par un cabochon, comme illustré par la figure 5 où il est désigné par la référence 2a. Dans ce cas, l'élément plat 2 lui servant de fond est bordé par une virole périphérique cylindrique 2'a dont la section transversale polygonale correspond à clle du mandre 3 de la raquette. Cette virole 2'a est dimensionnée de manière à pouvoir être engagée sur l'extrémité libre du manche 3 de la raquette en le serrant radialment. Dans ce cas, chaque secteur triangulaire 4,5 et 6 est prolongé, sur la face externe de la virole 2'a, par un secteur cylindrique portant le même signe distinctif que lui-même, respectivement 4', 5' et 6'. Cela facilite le repérage par le joueur de la bonne prise de raquette puisque cette disposition rend les secteurs plus facilement visibles.This tip can also be constituted by a cap, as illustrated in FIG. 5 where it is designated by the reference 2a. In this case, the flat element 2 serving as its bottom is bordered by a cylindrical peripheral ferrule 2'a, the polygonal cross section of which corresponds to the key of the racket 3. This ferrule 2'a is dimensioned so as to be able to be engaged on the free end of the handle 3 of the racket by tightening it radially. In this case, each triangular sector 4,5 and 6 is extended, on the external face of the shell 2 ′ a, by a cylindrical sector bearing the same distinctive sign as itself, respectively 4 ′, 5 ′ and 6 ′. This makes it easier for the player to identify the correct racket grip since this arrangement makes the sectors more easily visible.

Pour faciliter encore le réparage de la bonne prise de raquette par le joueur, suivant encore une autre caractéristique de l'invention et dans le cas où le manche 3 de la raquette est équipé, à son extrémité opposée à son extrémité libre portant l'embout 2, d'une bague 14, il est prévu, sur la face externe de cette bague, des secteurs cylindriques 4",5",6" dont chacun est disposé dans le prolongement de l'un des secteurs cylindriques 4' à 6' de la virole 2'a de l'embout 2a.To further facilitate the repair of the correct racket grip by the player, according to yet another characteristic of the invention and in the case where the handle 3 of the racket is equipped, at its end opposite to its free end carrying the tip 2, a ring 14, there are provided, on the outer face of this ring, cylindrical sectors 4 ", 5", 6 "each of which is arranged in the extension of one of the cylindrical sectors 4 'to 6' of the ferrule 2'a of the end piece 2a.

La figure 6, qui est une vue similaire aux figures 2 à 4, montre cet embout de raquette, qu'il soit ou non équipé d'une virole 2'a, dans le cas où il porte un quatrième secteur triangulaire, et éventuellement un secteur cylindrique, différents des trois premiers et désignés par les références, respectivement, 13 et 13'. Ces secteurs 13,13' correspondent à une prise de raquette permettant d'augmenter l'effet du lift en coup droit, cette prise de raquette étant généralement appelée "prise western". Il faut cependant noter que cette prise nécessite une grande expérience dans la pratique du tennis et n'est donc réservée qu'à des bons joueurs.Figure 6, which is a view similar to Figures 2 to 4, shows this racket tip, whether or not equipped with a ferrule 2'a, in the case where it carries a fourth triangular sector, and possibly a cylindrical sector, different from the first three and designated by the references, respectively, 13 and 13 '. These sectors 13, 13 ′ correspond to a racket grip making it possible to increase the effect of the forehand lift, this racket grip being generally called "western grip". However, it should be noted that this grip requires a great deal of experience in the practice of tennis and is therefore only reserved for good players.

La figure 7 montre une variante d'exécution de l'embout de l'invention, que cet embout comporte ou non une virole cylindrique 2'a. Partant du principe que les trois ou quatre secteurs triangulaires 4 à 6 et 13 et éventuellement cylindriques 4' à 6' et 13' à 4" à 6" et 13", ne s'étendent pas sur plus de 180°, il est prévu deux jeux de secteurs triangulaires et éventuellement cylindriques disposés symétriquement par rapport à l'axe 3" du manche 3 de la raquette. Cette disposition permet au joueur de faire pivoter sa raquette de 180° sans perdre le bénétice de la présente des repères sectoriels triangulaires ou cylindriques facilitant sa prise de raquette.FIG. 7 shows an alternative embodiment of the end piece of the invention, whether or not this end piece includes a cylindrical ferrule 2'a. Assuming that the three or four triangular sectors 4 to 6 and 13 and possibly cylindrical 4 'to 6' and 13 'to 4 "to 6" and 13 ", do not extend over 180 ° , it is expected two sets of triangular and possibly cylindrical sectors arranged symmetrically with respect to the axis 3 "of the handle 3 of the racket. This arrangement allows the player to rotate his racket 180 ° without losing the benefit of the present triangular or cylindrical sectoral marks facilitating his grip racket.
