Abstract

A stringing system for a racket consisting of two elements, a prewoven net of individual strings and a two piece fixing device, acting as a string clamp in the string hole of a racket frame under the string's own tension. A first member of the fixing device is tubular in shape and is designed to extend through the interior of the racket frame hole. Its upper portion extends outward from the frame hole and has a slot which separates it into two half shells. A second member of the fixing device is placed over the frame hole and is located entirely exteriorly of the hole. The exterior surface of the second member is adapted to the profile of the racket frame. During stringing of the racket, the first member is placed inside the second member and into the frame hole. The string is passed through the hole in the first member, such that when the first member slides into the second member, its two half shells are pressed together around the string to hold the string in place when under tension.

Description

L'invention se rapporte à une raquette munie d'un dispositif de fixation de cordes, par exemple une raquette de tennis, comprenant une pièce d'appui posée contre l'extérieur du cadre et une pièce sertissant la corde en coulissant à l'intérieur du trou conique de la pièce d'appui.The invention relates to a racket provided with a device for fixing strings, for example a tennis racket, comprising a support piece placed against the outside of the frame and a piece crimping the rope by sliding inside of the conical hole of the support piece.

Les dispositifs de fixation connus jusqu'à présent, fonctionnant de manière à sertir la corde pour la fixer en place, nécessitent la fabrication d'un cadre de raquette spécialement conçu ou transformé pour recevoir ce genre de fixation.The fixing devices known up to now, operating so as to crimp the rope to fix it in place, require the manufacture of a racket frame specially designed or transformed to receive this kind of fixation.

Les plus fréquentes transformations sont l'agrandissement des ouvertures, pour pouvoir poser les fixations à l'intérieur de celles-ci. Chez Buteleux, dans le brevet CH-A-356702, les douilles conqiques pénètrent à l'intérieur du trou du cadre, et le serrage des cordes s'effectue à l'intérieur des douilles coniques. Pour pouvoir placer ces douilles coniques à l'intérieur des ouvertures du cadre de la raquette (page 2, ligne 10) il est nécessaire de transformer les ouvertures du cadre, en les agrandissant et de donner une forme conique aux douilles (fig. 2).The most frequent transformations are the enlargement of the openings, in order to be able to place the fasteners inside them. At Buteleux, in patent CH-A-356702, the conical sockets penetrate inside the hole of the frame, and the strings are tightened inside the conical sockets. To be able to place these conical sockets inside the openings of the racket frame (page 2, line 10) it is necessary to transform the openings of the frame, by enlarging them and to give a conical shape to the sockets (fig. 2) .

Le système employé par Vaughn et Parker, - voir la demande de brevet GB-A-2058902, selon fig. 5, 7a, 8b le serrage de la corde s'effectue dans des ouvertures conçues spécialement à cet effet, à l'intérieur de la raquette.The system used by Vaughn and Parker, - see patent application GB-A-2058902, according to fig. 5, 7a, 8b the tightening of the rope takes place in openings specially designed for this purpose, inside the racket.

L'inconvénient de tous ces systèmes est que les pièces en forme de cheville conique et les douilles de serrage se placent à l'intérieur des ouvertures, agrandies pour pouvoir loger l'ensemble du système dans la cadre. De ce fait, leur emploi se limite à une raquette spécifiquement fabriquée ou transformée à cet effet.The disadvantage of all these systems is that the conical pin-shaped parts and the clamping sleeves are placed inside the openings, enlarged to be able to accommodate the entire system in the frame. Therefore, their use is limited to a racket specifically manufactured or transformed for this purpose.

La présente invention a pour but de remédier à ces inconvénients. L'invention est caractérisée en ce que la pièce d'apui, voie Fig. 3 no. 10, pénètre pas à l'intérieur du passage des cordes mais est posée en appui à l'extérieur, sur le cadre.The present invention aims to remedy these drawbacks. The invention is characterized in that the support piece, track Fig. 3 no. 10, does not penetrate inside the passage of the cords but is placed in abutment on the outside, on the frame.

Le serrage s'effectue par la pièce 9 à l'extérieur des trous. L'avantage obtenu grâce à cette invention, consiste essentiellement en ce que le dispositif de fixation peut être monté sur tous les cadres sans effectuer de transformations, en agrandissant les ouvertures.The tightening is carried out by the part 9 outside the holes. The advantage obtained thanks to this invention consists essentially in that the fixing device can be mounted on all the frames without carrying out transformations, by enlarging the openings.

L'invention est exposée ci-après plus en détails à l'aide des Figures 1, 2 et 3 représentant seulement un mode d'exécution. Pour fixer une corde en place, le dispositif de fixation est placé sur l'extérieur du cadre et la corde individuelle enfilée dans le trou du dispositif de fixation. La corde est tendue à la tension désirée et fixée, à son extrémité, par le dispositif de fixation.The invention is set out below in more detail using Figures 1, 2 and 3 showing only one embodiment. To fix a rope in place, the fixing device is placed on the outside of the frame and the individual rope threaded into the hole of the fixing device. The rope is stretched to the desired tension and fixed at its end by the fixing device.

Le dispositif comporte la première pièce (9), dont la partie supérieure (11) est formée de deux demi-coques tronconiques séparées par la fente (15) qui entour la corde (7) au moment du serrage. La pièce (9) coulisse dans la deuxième pièce (10) dont le profil extérieur est adapté à la forme du cadre (4). Le trou (13) est conique. Lors du cordage, la pièce (9) est placée dans la pièce (10). La corde est glissée de l'intérieur vers l'extérieur du cadre, puis tendue tout en maintenant le dispositif de fixation en contact avec le cadre. Dès que la pièce (9) est poussée en position de serrage, la tension est relachée. La pièce (9) fonctionne comme une machoire. Les deux demi-coques sont forcées contre la corde par l'effet de la pièce (9) coincée contre la pièce (10). Un petit tube en matière élastique (14) peut être placé au bas de la pièce (9), entre celle-ci et le trou du cadre. Ce tube permet de maintenir le système de fixation en place, en face du trou, ce qui peut être avantageux lorsqu'une raquette est équipée de ce système en fabrique et doit être expédiée sans que le système de fixation ne se perde.The device comprises the first part (9), the upper part (11) of which is formed by two frustoconical half-shells separated by the slot (15) which surrounds the rope (7) when tightening. The part (9) slides in the second part (10) whose external profile is adapted to the shape of the frame (4). The hole (13) is conical. When stringing, the part (9) is placed in the part (10). The rope is slid from the inside to the outside of the frame, then stretched while keeping the fixing device in contact with the frame. As soon as the part (9) is pushed into the clamping position, the tension is released. The part (9) functions like a jaw. The two half-shells are forced against the rope by the effect of the part (9) wedged against the part (10). A small tube of elastic material (14) can be placed at the bottom of the part (9), between the latter and the hole in the frame. This tube keeps the fixing system in place, opposite the hole, which can be advantageous when a racket is equipped with this system in the factory and must be shipped without the fixing system being lost.

Claims (3)

1. A racquet equipped with a string clamping device on the frame, this device consisting of two reusable parts:
- the first part (9) in tubular form with a diameter smaller than the holes in the racquet frame, equipped (4) with a lower part having an internal diameter larger than that of the string (7), and an upper section having a slit (15) with a width of at least 30% of the diameter of the string (7), this slit separates the upper part of the tube into two half sections with a conical surface which widens at the top and the internal surface of which is equipped with a screwing device (12), the internal diameter being smaller than that of the string when the two sections close in together.
- a second part (10), having an internal conical (13). The full diameter of this hole is situated on the outside of the frame in such a way that the two parts fit one into another during the stringing, one string crossing the first part, the upper section facing the frame exterior and sliding into the second and equipped with a conical hole which clamps the two half- sections of the first part around the string, thus fixing it into position. The clamping device is characterized by the fact that the second part (10) is adapted to remain stable on the frame of the racquet, since it is located entirely on the external parts of the holes, and the external shape of this part is adapted to the external profile of the frame.
