Abstract

The invention relates to a racket frame making it possible to have greater comfort, greater control and greater power at the moment of striking the ball. The frame is a composite frame formed from rigid materials 1 and from elastic materials 2. The very composition of these elements according to Figure 1 gives the stringing the property of relaxing at the moment of impact and of regaining its tension at the moment of the rebound. The invention is intended particularly for tennis, squash or other types of rackets.

Description

La présente invention concerne un cadre de raquette comportant des moyens élastiques permettant sa déformation sous l'impact de la balle
Les cadres de raquette sont traditionnellement rigides . Cette rigidité transmet certaines vibrations au bras du joueur ainsi que l'impact du choc ce qui est quelquefois inconfortable ; cela peut être aussi une source de douleur au coude ( maladie connue sous le nom de " Tennis-elbow " )
Une réalisation selon l'invention consiste à introduire des moyens élastiques dans un cadre rigide
Ces moyens élastiques permettent : - d'assouplir les coups ; - d'amortir les vibrations et les chocs ; - de renvoyer la balle plus fort ; - d'exercer un meilleur contrôle sur la balle ;
Selon une forme de réalisation préférentielle, le cadre est composé de deux matériaux:Un matériaux élastique (1) de type caoutchouc ou autre matériaux élastique, associé à un matériaux dur et rigide de type alluminium ( en profilé ) ou tout autre matériaux rigide.
The present invention relates to a racket frame comprising elastic means allowing its deformation under the impact of the ball.
Racket frames are traditionally rigid. This rigidity transmits certain vibrations to the player's arm as well as the impact of the shock which is sometimes uncomfortable; it can also be a source of elbow pain (a condition known as "tennis-elbow")
An embodiment according to the invention consists in introducing elastic means into a rigid frame
These elastic means make it possible: - to soften the blows; - dampen vibrations and shocks; - return the ball louder; - to exercise better control over the ball;
According to a preferred embodiment, the frame is composed of two materials: An elastic material (1) of rubber type or other elastic material, associated with a hard and rigid material of aluminum type (in profile) or any other rigid material.

Le matériaux élastique (1) peut être soit " pris en sandwich " entre deux matériaux rigides (2) ( fig 1 ) , soit fixé sur un matériaux rigide (2) ( fig 2 ). The elastic material (1) can be either "sandwiched" between two rigid materials (2) (fig 1), or fixed on a rigid material (2) (fig 2).

Concernant la réalisation selon la fig 1, on peut aussi fixer entre les deux côtés rigides des éléments élastiques séparés et uniformément répartis de type boudins ou petites bobines ou ressort à la place de l'élément élastique continu et perçé pour le passage des cordes. (6)
Sur chaque élément élastique séparé repose une corde.
Concerning the embodiment according to FIG. 1, it is also possible to fix, between the two rigid sides, separate and uniformly distributed elastic elements of the strand or small coil or spring type in place of the continuous elastic element pierced for the passage of the strings. (6)
On each separate elastic element rests a rope.

Selon une variante du système de l'invention, ( FIG 3 ) la partie ciconférente d'un cadre rigide (1) est coupée en un ou plusieurs endroits où l'on insere un élément élstique (2) de type caoutchouc, ressort ou autre . La
FIG 4 montre le détail d'une de ces insertion ; le moyen élastique n'est pas déformé; la raquette ne frappe pas de balle . La FIG 5 représente le meme dispositif mais au moment de l'impact . Le moyen élastique est comprimé
Bien sur la balle va rebondir et le dispositif reprendra la position initiale de la FIG 4 . Une tige rigide (3) est visible sur les figures 4 et 5 . Elle sert à assurer que la déformation du cadre ne puisse se produire que dans le plan du cadre ( ni torsion, ni vrillage ) . La tête (5) de la tige assure une fixité à l'une des extrémités .L'autre extrémité de la tige est une partie mâle qui pénetre dans le vide (4) du cadre au moment du coup
Selon une variante du système de l'invention décrit jusqu'à lors, la FIG 6 représente une corde (6) du cordage reposant directement sur un moyen élastique (2) . Cette disposition sur le cadre doit être réalisé pour toutes les cordes ou pour une majorité de cordes . Au moment de la frappe, FIG 7 la corde tire sur le moyen élastique ce qui a pour effet de l'écraser
Selon une autre variante FIG 8, la corde (6) repose sur un élement rigide (7) qui lui repose sur les moyens élastiques (2) à l'intérieur du cadre (1) . Pour cette variante il faut utiliser un cadre de type profilé métalique creux .La FiG 9 représente le meme dispositif mais au moment de l'impact avec la balle
Les figures 10,11, 12 et 13 représentent un shéma explicatif des changements de déformation du moyen élastique au cours du cycle - figl0; le moyen élastique n'est sousmis a aucune force ( c'est dans la réalité lorsque le cadre de raquette n'est pas cordé ) - fig il; Le cadre est cordé; la tension du cordage déforme déja le moyen élastique - fig 12; quand la force d'une balle (8) vient s'ajouter à la tension initiale du cordage, le moyen élastique subit alors une déformation beaucoup plus importante - fig 13; la balle rebondit et est de plus propulsée par le moyen élastique qui tend à reprendre sa position; quand la balle quitte le cordage, le moyen élastique a completement repris sa position initiale de la fig (10).
According to a variant of the system of the invention, (FIG 3) the coniferous part of a rigid frame (1) is cut in one or more places where an elastic element (2) of rubber, spring or other type is inserted. . The
FIG 4 shows the detail of one of these insertions; the elastic means is not deformed; the racket does not strike a ball. FIG 5 shows the same device but at the time of impact. The elastic means is compressed
Of course the ball will rebound and the device will return to the initial position of FIG 4. A rigid rod (3) is visible in Figures 4 and 5. It is used to ensure that the deformation of the frame can only occur in the plane of the frame (no twisting or twisting). The head (5) of the rod provides fixity at one end. The other end of the rod is a male part which penetrates into the void (4) of the frame at the time of the blow.
According to a variant of the system of the invention described until then, FIG 6 shows a rope (6) of the rope resting directly on an elastic means (2). This arrangement on the frame must be made for all the strings or for a majority of strings. At the time of striking, FIG 7 the rope pulls on the elastic means which has the effect of crushing it
According to another variant FIG 8, the rope (6) rests on a rigid element (7) which rests on the elastic means (2) inside the frame (1). For this variant it is necessary to use a frame of hollow metal profile type. The FiG 9 represents the same device but at the time of impact with the bullet
Figures 10,11, 12 and 13 show an explanatory diagram of the changes in deformation of the elastic means during the cycle - figl0; the elastic means is not subjected to any force (it is in reality when the racket frame is not strung) - fig il; The frame is strung; the tension of the rope already deforms the elastic means - fig 12; when the force of a ball (8) is added to the initial tension of the rope, the elastic means then undergoes a much greater deformation - fig 13; the ball bounces and is further propelled by the elastic means which tends to return to its position; when the ball leaves the rope, the elastic means has completely returned to its initial position in fig (10).

Le cadre selon l'invention est particulierement destiné au jeu du Tennis,
Squash et autre jeux utilisant des raquettes
The frame according to the invention is particularly intended for the game of Tennis,
Squash and other games using rackets
