Abstract
Description
L'invention concerne une raquette de jeux de balles à monture ou carcasse pliante et séparable.The invention relates to a racket for ball games with a folding and separable frame or carcass.
Toutes les raquettes d'un seul tenant présentent un certain nombre d'inconvénients. En effet, elles ont un encombrement non négligeable pour les personnes appelées à se déplacer avec leurs raquettes. Il estdifficile de ranger une raquette dans un sac, bien souvent le manche en dépasse. Les housses prévues pour leur rangement n'enveloppent bien souvent que le tamis, laissant dépasser le manche.All snowshoes in one piece have a number of drawbacks. In fact, they have a considerable size for people called to move with their snowshoes. It is difficult to put a racket in a bag, often the handle sticks out. The covers provided for their storage very often only wrap the sieve, leaving the handle sticking out.
D'autre part, il existe un grand nombre de tailles et de formes de tamis, ce qui oblige, pour les essayer, d'acquérir plusieurs raquettes. De plus, le revêtement qui entoure le manche doit être changé plusieurs fois au cours d'une même partie pour avoir une grande efficacité. De même, le cordage du tamis peut nécessiter un changement en cours de partie, soit parce qu'il s'est détérioré, soit parce que le jeu du partenaire nécessite une tactique différente, le cordage pour jeux d'attaques sera plus tendu que le cordage pour jeux défensifs. En outre, les vibrations émises par le choc de la balle sur le tamis sont répercutées directement au manche puis au bras du joueur.On the other hand, there are a large number of sizes and shapes of sieves, which requires, to try them, to acquire several rackets. In addition, the coating that surrounds the handle must be changed several times during the same game to be very effective. Likewise, the line of the sieve may require a change during the game, either because it has deteriorated, or because the partner's game requires a different tactic, the line for attack games will be tighter than the line for defensive games. In addition, the vibrations emitted by the impact of the ball on the sieve are reflected directly on the handle and then on the player's arm.
On connaît des raquettes de jeux de balles dont le manche peut être rabattu sur le tamis, comme illustré par exemple dans le brevet FR-A-1 423 709, ou encore dans le brevet US-A-1 673 614.Ball rackets are known, the handle of which can be folded down over the sieve, as illustrated for example in patent FR-A-1,423,709, or even in patent US-A-1,673,614.
Il s'agit cependant de solutions très rudimentaires qui n'ont connu aucun développement pratique, essentiellement parce que le problème du blocage de l'articulation entre le manche et le tamis n'y a pas trouvé de solution efficace.However, these are very rudimentary solutions which have not seen any practical development, essentially because the problem of blocking the joint between the handle and the sieve has not found an effective solution.
La présente invention vise à remédier à ces inconvénients et à apporter divers avantages, en proposant une raquette de jeux de balles, formée d'un manche et d'un tamis ou similaire, montés l'un par rapport à l'autre avec articulation autour d'un axe, caractérisée en ce que le tamis comporte un cadre pourvu de deux bras se prolongeant de part et d'autre du mache et venant jusqu'au contact de celui-ci, des têtons d'arrêt disposés sur le manche coopérant avec des entailles prévues sur les bras du cadre, un dispositif de fixation étant prévu entre l'extrémité du manche et le cadre du tamis, l'articulation étant réalisée par une épingle d'articulation à déport d'axe, cette épingle ayant la forme d'un oméga et présentant des tronçons d'articulation d'axes différents coopérant avec le manche et avec les bras du cadre respectivement et en ce qu'il est prévu des dispositifs amortisseurs de vibration interposés entre le manche et le cadre, ainsi qu'entre le manche et les bras du cadre.The present invention aims to remedy these drawbacks and to provide various advantages, by proposing a racket for ball games, formed of a handle and a sieve or the like, mounted relative to each other with articulation around an axis, characterized in that the sieve comprises a frame provided with two arms extending on either side of the bit and coming into contact with the latter, stop pins arranged on the handle cooperating with notches provided on the arms of the frame, a fixing device being provided between the end of the handle and the frame of the screen, the articulation being produced by an articulation pin with offset axis, this pin having the form d '' an omega and having articulation sections of different axes cooperating with the handle and with the arms of the frame respectively and in that there are provided vibration damping devices interposed between the handle and the frame, as well as between the handle and arms of the frame.
L'invention propose également une raquette de jeux de balles, formée d'un manche et d'un tamis ou similaire, montés l'un par rapport à l'autre avec articulation autour d'un axe, caractérisée en ce que le manche se termine en fourche par deux bras rejoignant le tamis en deux points écartés l'un de l'autre et le tamis comporte un prolongement longitudinal rejoignant le mache à la jonction des deux bras, des dispositifs de fixation étant prévus aux extrémités des bras ainsi qu'à l'extrémité du prolongement, l'articulation étant réalisée par une épingle d'articulation à déport d'axe, cette épingle ayant la forme d'un oméga et présentant des tronçons d'articulation d'axes différents coopérant avec les bras du manche et avec le prolongement du tamis respectivement et en ce qu'il est prévu des dispositifs amortisseurs de vibration interposés entre le manche et le prolongement du tamis, ainsi qu'entre les bras du manche et le tamis.The invention also provides a ball racket, formed of a handle and a sieve or the like, mounted relative to each other with articulation around an axis, characterized in that the handle is ends in a fork with two arms joining the sieve at two points spaced from each other and the sieve has a longitudinal extension joining the cheek at the junction of the two arms, fixing devices being provided at the ends of the arms as well as at the end of the extension, the articulation being produced by an articulation pin with offset axis, this pin having the shape of an omega and having articulation sections of different axes cooperating with the arms of the handle and with the extension of the sieve respectively and in that there are provided vibration damping devices interposed between the handle and the extension of the sieve, as well as between the arms of the handle and the sieve.
Grâce à l'invention, le manche se plie sur le tamis ou vice-versa, ce qui permet un rangement aisé dans une housse prévue à cet effet, ayant la forme d'un tamis et suffisamment large pour contenir éventuellement plusieurs tamis et plusieurs manches.Thanks to the invention, the handle folds over the sieve or vice-versa, which allows easy storage in a cover provided for this purpose, having the shape of a sieve and wide enough to possibly contain several sieves and several sleeves. .
Il devient également possible de séparer tamis et manche en prévoyant une articulation.démontable. Ceci donne la possibilité de pouvoir adapter n'importe quelle taille de tamis à n'importe quelle taille de manche et vice-versa. Il devient aussi possible à un enfant de jouer avec le tamis d'un adulte en y adaptant son manche, et à un même joueur d'avoir plusieurs tamis de différentes tailles ou différentes formes, ou encore avec des tensions de cordage différentes, ainsi que plusieurs manches avec des revêtements différents prêts à être employés à tout moment. La réalisation de poignées anatomiques, c'est-à-dire modelées suivant la main du joueur lui-même, pourra être effectuée indépendamment du tamis. Le tamis et la manche deviennent donc deux parties distinctes reliées entre elles par leur articulation, séparées par des joints amortisseurs les vibrations ne sont plus conduites au bras du joueur, réduisant les problèmes d'articulations du coude du joueur.It also becomes possible to separate the sieve and handle by providing a removable hinge. This gives the possibility of being able to adapt any size of sieve to any size of handle and vice versa. It also becomes possible for a child to play with the sieve of an adult by adapting its handle to it, and for the same player to have several sieves of different sizes or different shapes, or even with different rope tensions, as well as several handles with different coatings ready to be used at any time. The realization of anatomical handles, that is to say, shaped according to the hand of the player himself, can be carried out independently of the sieve. The sieve and the sleeve therefore become two separate parts connected to each other by their articulation, separated by damping seals the vibrations are no longer conducted to the player's arm, reducing the problems of articulations of the player's elbow.
Du point de vue des fabricants de raquettes, on observera que le manche et le tamis étant deux éléments distincts, on pourra organiser leur fabrication suivant des technologies différentes, chaque élément ayant une taille et un poids nettement inférieurs à ceux d'une raquette monobloc, ce qui permet de simplifier l'outillage de production. Les défauts de fabrication n'entraîneront pas la mise au rebut d'une raquette entière mais seulement de celui des deux éléments, manche ou tamis, qui est concerné. Enfin, le conditionnement de transport, de livraison et de présentation pourra être simplifié, et donner lieu à de nouvelles formes originales.From the point of view of the racket manufacturers, it will be observed that the handle and the sieve being two distinct elements, it will be possible to organize their manufacture according to different technologies, each element having a size and a weight clearly lower than those of a one-piece racket, which simplifies the production tools. Manufacturing defects will not result in the scrapping of an entire racket but only that of the two elements, handle or sieve, which is concerned. Finally, the packaging of transport, delivery and presentation can be simplified, and give rise to new original forms.
Divers détails et avantages de l'invention apparaîtront clairement à la lecture de la description qui va suivre en se référant aux dessins annexés, dans lesquels:
- - Les figures 1 et 2 illustrent une raquette articulée conforme à l'invention
- - La figure 3 illustre une variante de raquette analogue à celle de la figure 1.
- - Figures 1 and 2 illustrate an articulated racket according to the invention
- - Figure 3 illustrates a variant racket similar to that of Figure 1.
Dans le mode de réalisation illustré à la figure 1, le cadre 18 du tamis 14 de raquette est prolongé par deux bras 86, 88 qui se terminent contre le manche 12. Les extrémités des bras 86, 88 sont entaillées et viennent coopérer avec des têtons 90, 92 d'arrêt en saillie sur les deux flancs du manche. Le manche 12 s'étend jusqu'au contact de l'embase 94 du cadre, sur lequel il est fixé par un moyen amovible, par exemple un dispositif à came ou à excentrique 96 fixé à l'extrémité du manche et coopérant avec une tige à tête 98 sertie dans le cadre.In the embodiment illustrated in Figure 1, the
Une épingle d'articulation 100 est montée entre les bras du cadre et le manche et assure un déport d'articulation pour permettre un rabattement du manche «à plat» contre le tamis.A
Comme illustré sur la vue de détail accolée à la figure, l'épingle d'articulation 100 a sensiblement la forme d'un oméga, et présente un tronçon d'articulation central 1 OOc traversant le manche et définissant un premier axe d'articulation XX, et deux tronçons d'articulation externes 100e traversant les bras du cadre et définissant un second axe d'articulation YY.As illustrated in the detail view attached to the figure, the
Ainsi, lorsque le manche 12 est désolidarisé du cadre, par libération du dispositif à came 96, on peut basculer le manche de dégager les tétons 90, 92 des entailles d'extrémité des bras 86, 88 en un premier temps, puis on poursuit le basculement du manche jusqu'à le rabattre contre le tamis 14.Thus, when the
Les figures 2a à 2d illustrent schématiquement les phases successives de basculement et de rabattement du manche.

Pour faciliter la compréhension, l'épingle 100 y a été figurée en traits pleins, bien que normalement cachée par les éléments de la raquette.To facilitate understanding, the
Dans la variante illustrée à la figure 3, on a inversé la disposition de la figure 1, c'est-à-dire que le manche se termine en fourche par deux bras 102 et 104 qui rejoignent le cadre du tamis en deux points espacés 106 et 108 et le cadre comporte un prolongement longitudinal 110 qui rejoient le manche à la jonction des deux bras 102 et 104.In the variant illustrated in Figure 3, we have reversed the arrangement of Figure 1, that is to say that the handle ends in fork by two
Cette disposition améliore la tenue en torsion du manche par rapport aux tamis.This arrangement improves the torsional behavior of the handle relative to the sieves.
Bien entendu, ici également l'articulation est réalisée au moyen d'une épingle 100 d'articulation à déport d'axe identique à celle qui vient d'être décrite en relation avec la figure 1. Des dispositifs de fixation amovibles, non représentés sont prévus aux extrémités des bras ainsi qu'à l'extrémité du prolongement.Of course, here also the articulation is produced by means of a
Ces types de montage apportent à l'utilisateur et au fabricant de nombreux avantages qui ont déjà été évoqués en introduction et ne seront donc pas répétés ici.These types of assembly provide the user and the manufacturer with numerous advantages which have already been mentioned in the introduction and will therefore not be repeated here.
Pour terminer cette description, on mentionnera que les éléments destinés à l'amortissement des vibrations, dans tous les modes de réalisation, peuvent être réalisés de manière interchangeable, la raquette étant fournie avec un jeu de plaquettes ou autres éléments amortisseurs de vibrations présentant des caractéristiques différentes et que l'utilisateur pourra choisir selon le résultat désiré. Dans certains cas, il pourra utiliser plusieurs éléments afin de combiner leurs caractéristiques.To complete this description, it will be mentioned that the elements intended for vibration damping, in all the embodiments, can be produced interchangeably, the racket being provided with a set of pads or other vibration damping elements having characteristics different and that the user can choose according to the desired result. In some cases, it may use several elements to combine their characteristics.
Entre le manche et le tamis, au niveau de l'articulation, est interposée une plaque 36 en matériau amortisseur de vibrations, destinée à empêcher la propagation des vibrations depuis le tamis vers le manche, ce qui évite des troubles physiologiques à l'utilisateur de la raquette.Between the handle and the sieve, at the articulation, is interposed a plate 36 of vibration-absorbing material, intended to prevent the propagation of vibrations from the sieve to the handle, which avoids physiological disturbances for the user. racket.
Tous les modes de réalisation décrits présentent l'avantage commun que les manches et les tamis y sont montés avec articulation l'un par rapport à l'autre, et qu'il est prévu un dispositif de blocage de l'articulation, situé à distance de l'axe d'articulation, ainsi qu'un dispositif amortisseur de vibrations interposé entre le manche et le tamis.All the embodiments described have the common advantage that the sleeves and the sieves are mounted therein with articulation relative to each other, and that a joint locking device is provided, located at a distance of the hinge pin, as well as a vibration damping device interposed between the handle and the screen.
Bien que cela n'ait pas été décrit, on comprendra que toutes les parties du manche et du tamis qui sont en contact en position de fonctionnement peuvent présenter des formes d'emboîtement complémentaires afin de compléter les moyens de serrage et/ou de blocage prévus spécifiquement dans chaque cas.Although this has not been described, it will be understood that all the parts of the handle and of the screen which are in contact in the operating position may have complementary forms of interlocking in order to complete the clamping and / or blocking means provided. specifically in each case.
De plus, on pourra sans sortir du cadre de l'invention, adjoindre à l'articulation des ressorts qui ramènent automatiquement le manche et le tamis dans le prolongement l'un de l'autre - ou au contraire en rabattement l'un contre l'autre - pour simplifier la manoeuvre.In addition, without departing from the scope of the invention, add to the joint springs which automatically bring the handle and the sieve in line with one another - or on the contrary by folding one against the 'other - to simplify the operation.
