Description

DISPOSITIF ANTI-VIBRATOIRE POUR RAQUETTE DE JEU A BALLE
La présente invention concerne un dispositif anti-vibratoire pour raquette de tennis ou de jeu à balle composé d'un élément en matière thermoplastique pourvue d'un apendice s'étroitisant, se fixant sur les cordes du tamis. Ce dispositif sert à absorber les vibrations générée par le tamis suite à un impact de balle.
ANTI-VIBRATORY DEVICE FOR BALL GAME RACKET
The present invention relates to an anti-vibration device for a tennis racket or a ball game consisting of a thermoplastic element provided with a narrowing appendage, which is fixed to the strings of the sieve. This device is used to absorb the vibrations generated by the sieve following a bullet impact.

II est bien connu qu' un élément en élastomère ou en thermoplastique placé sur les cordes d'un tamis attenu les vibrations de ce dernier. Les dispositifs existant à ce jour offrent des imperfections. Ainsi, le brevets 1 398833 du 5/4/65 n'offre pas de maintien suffisant sur le tamis. Le brevet 2630 019 du 14/4/88 comporte bien un appendice de maintien, mais celle-ci, de forme linéique constante, doit être de forte section pour être rigide et assurer un maintien correct, ce qui entraine une augmentation de poids inutile propre à freiner le rendement du tamis. It is well known that an elastomer or thermoplastic element placed on the strings of a sieve attenuates the vibrations of the latter. The devices existing to date offer imperfections. Thus, patent 1 398833 of 5/4/65 does not offer sufficient support on the sieve. Patent 2630 019 of 04/14/88 does indeed have a support appendage, but this one, of constant linear form, must be of large section to be rigid and ensure correct support, which leads to an unnecessary unnecessary weight gain. to slow down the performance of the sieve.

La présente invention permet de remédier à ces inconvénients. The present invention overcomes these drawbacks.

Dans une matérialisation préférentielle, le dispositif est constitué d'un élément principal en thermoplastique possédant un appendice s'agrippant au cordage du tamis. Cet appendice est caractérisé par une variation de sa section, plus importante au lieu de son départ à l'élement principal, et décroissante sur au moins une partie de sa longueur. Cette appendice à section variée, plus rigide à masse égale qu'une section continue, permet d'assurer un parfait maintien du dispositif dans la raquette tout en offrant un poids réduit. In a preferred embodiment, the device consists of a main thermoplastic element having an appendage gripping the cord of the screen. This appendage is characterized by a variation in its section, which is greater instead of its departure from the main element, and decreasing over at least part of its length. This appendage with varied section, more rigid with equal mass than a continuous section, makes it possible to ensure a perfect maintenance of the device in the racket while offering a reduced weight.

Les vibrations sont captées directement par la matière absorbante du dispositif.The vibrations are captured directly by the absorbent material of the device.

Dans une variante, le dispositif comporte une gorge sur au moins un de ses cotés latéraux, afin de le fixer entre les cordes du tamis. Le dispositif peut alors se positionner parallélement et dans le plan du tamis mais en biais par rapport à l'axe longitudinal de symétrie de la raquette, les appendices de dimension réduits venant s'agriper de chaque côtés d'une corde longitudinale. In a variant, the device has a groove on at least one of its lateral sides, in order to fix it between the strings of the sieve. The device can then be positioned parallel and in the plane of the sieve but at an angle with respect to the longitudinal axis of symmetry of the racket, the appendages of reduced size coming to grip each side of a longitudinal rope.

Le dispositif est réalisé en élastomère ou thermoplastique par moulage de type compression ou injection. II peut être fabriqué par découpe directe sur des planches de matiére souples, rigide, ou semi-rigides. The device is made of elastomer or thermoplastic by compression or injection type molding. It can be manufactured by direct cutting on flexible, rigid, or semi-rigid material boards.

Sa mise en place s'exécute par déformation de sa matière si celle-ci est souple et en l'insérant entre des cordes du tamis. Si la matière du dispositif est rigide, les cordes sont déplacées par la main de l'humain qui insère le dispositif alors muni de cavités sur tout ou partie de ses côtés. Une fois mis en place, les cordes reprennent leurs positions originelles et se retrouvent contre le dispositif. Its implementation is carried out by deformation of its material if it is flexible and by inserting it between strings of the sieve. If the material of the device is rigid, the strings are moved by the hand of the human who inserts the device then provided with cavities on all or part of its sides. Once in place, the strings return to their original positions and are found against the device.

A titre d'exemple, non limitatif, voici maintenant une description de l'invention se référant au dessin annexé dans lequel:
En référence à la figure 1 le dispositif anti-vibratoire pour raquette de tennis ou jeu à balle vu de face est fabriqué d'une matière plastique ou élastomère. II est composé d'un élément principal 1 de forme sensiblement parallélépipède à bords fortements arrondis qui se coince contre les cordes du tamis de la raquette. Cet élément 1 amortissant les vibrations du tamis de la raquette, est pourvu d'un appendice 2 de forme trapézoïdale assurant son maintien dans le tamis, caractérisé en ce que cet apendice 2 à sa section S1 plus importante au lieu de son départ de l'élément principal 1, laquelle décroît sur au moins une partie de sa longueur pour aboutir à la section S2 plus étroite.
By way of non-limiting example, here now is a description of the invention with reference to the attached drawing in which:
Referring to Figure 1 the anti-vibration device for tennis racket or ball game seen from the front is made of a plastic or elastomer. It is composed of a main element 1 of substantially parallelepiped shape with strongly rounded edges which is wedged against the strings of the sieve of the racket. This element 1 damping the vibrations of the sieve of the racket, is provided with an appendage 2 of trapezoidal shape ensuring its maintenance in the sieve, characterized in that this appendage 2 to its section S1 more important instead of its departure from the main element 1, which decreases over at least part of its length to reach the narrower section S2.

Si l'on se rapporte à la figure 2 montrant le dispositif vu de profil, on voit que l'appendice 2, décoissant en section suivant la direction D, constitue un prolongement de l'élement principal 1. If one refers to FIG. 2 showing the device seen in profile, it can be seen that the appendix 2, decreasing in section in the direction D, constitutes an extension of the main element 1.

Si l'on se rapporte à la figure 3 qui présente une variante de l'invention vue de profil, on voit que le dispositif comporte une gorge 3 sur au moins un des ses cotés latéraux, afin de l'insérer dans le tamis autour de la corde Cl . La partie inférieure est çonstituée de deux appendices de maintien 2 et 2bis de section décroissante dans la direction D de ses extrémités. Ces appendices 2 et 2bis se superposent formant la gorge 3 bis, ou prennent place les cordes C2 et C3 de chaque côtés. If one refers to FIG. 3 which presents a variant of the invention seen in profile, it can be seen that the device has a groove 3 on at least one of its lateral sides, in order to insert it into the sieve around the rope Cl. The lower part is made up of two retaining appendages 2 and 2bis of decreasing section in the direction D of its ends. These appendages 2 and 2bis are superimposed forming the groove 3a, or take place the cords C2 and C3 on each side.

II va de soit que les matérialisations de l'invention sont donnés à titre d'exemple, et que les variations de formes des éléments constitutifs, notament la longuer des appendices, ne sortiront pas du cadre de l'invention. It goes without saying that the embodiments of the invention are given by way of example, and that the variations in shape of the constituent elements, in particular the length of the appendages, will not depart from the scope of the invention.

La présente invention est particulièrement déstinée à absorber les vibrations d'une raquette de tennis ou jeu à balle avec l'avantage de s'agripper efficacement au tamis tout en offrant une masse réduite.  The present invention is particularly intended to absorb the vibrations of a tennis racket or ball game with the advantage of effectively gripping the sieve while providing a reduced mass.
