Description

La présente invention se rapporte à une poignée de raquette comportant, entre autres, un noyau destiné à être entouré par une couche de matière synthétique, elle-même générale­ment achevée par l'enroulement d'une lanière en cuir ou analogue.The present invention relates to a racket handle comprising, inter alia, a core intended to be surrounded by a layer of synthetic material, itself generally completed by winding a leather strap or the like.

Le but de l'invention est de réaliser une poignée de raquette dont la prise en main (grip) est considérablement améliorée tandis que les propriétés de frappe de la raquette peuvent être modifiées en fonction des besoins du joueur.The object of the invention is to provide a racket handle whose grip is considerably improved while the striking properties of the racket can be modified according to the needs of the player.

Un objet particulier de l'invention est pré­cisément une structure particulière permettant une interchangeabilité aisée et rapide d'éléments de poids.A particular object of the invention is precisely a particular structure allowing easy and rapid interchangeability of weight elements.

Pour réaliser ces objectifs, conformément à l'invention, la poignée de la raquette selon l'invention se termine par une pièce qui se présente sous la forme d'un embout qui se glisse sur l'extrémité du noyau de la poignée et comporte une partie qui, en position d'utilisation, s'étend au-delà de l'extrémité de la poignée, une partie qui entoure l'extrémité de la poignée et une partie centrale cylindrique creuse qui se glisse dans une cavité de section corres­pondante menagée dans l'axe du noyau de la poignée et qui est destinée à recevoir un élément de poids interchangeable tandis que la partie de l'embout qui entoure le noyau est destinée à être noyée dans la matière synthétique précitée.To achieve these objectives, according to the invention, the handle of the racket according to the invention ends in a part which is in the form of a tip which slides on the end of the core of the handle and comprises a part which, in the position of use, extends beyond the end of the handle, a part which surrounds the end of the handle and a hollow cylindrical central part which slides into a cavity of corresponding section made in the axis of the core of the handle and which is intended to receive an element of interchangeable weight while the part of the end piece which surrounds the core is intended to be embedded in the aforementioned synthetic material.

Toujours selon l'invention, l'embout précité présente une saillie périphérique située entre la partie qui, en position d'utilisation, s'étend au delà de la poignée précitée et la partie qui entoure l'extrémité précitée de la poignée, qui détermine la distance sur laquelle la partie de l'embout précité est noyé dans la matière synthétique.Still according to the invention, the aforementioned tip has a peripheral projection located between the part which, in the use position, extends beyond the aforementioned handle and the part which surrounds the aforementioned end of the handle, which determines the distance over which the part of the aforementioned tip is embedded in the plastic.

Dans une forme de réalisation avantageuse, la partie centrale cylindrique creuse précitée et l'élément de poids interchangeable coopèrent entre eux à la manière d'un assemblage à baïonnette, l'élément de poids interchangeable, de forme cylindrique, étant à cet effet pourvu de deux tétons et la partie centrale cylindrique creuse présentant deux creusures longitudinales dans les­quelles peuvent glisser les tétons précités.In an advantageous embodiment, the aforementioned hollow cylindrical central part and the interchangeable weight element cooperate with one another in the manner of a bayonet connection, the interchangeable weight element, of cylindrical shape, being for this purpose provided with two studs and the hollow cylindrical central part having two longitudinal recesses in which the aforementioned studs can slide.

D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'une poignée de raquette selon l'invention. Cette description n'est donnée qu'à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent au dessin ci-annexé.

  • La figure 1 est une vue explosée et en élévation montrant les éléments constitutifs de l'extrémité de la poignée selon l'invention.
  • La figure 2 est une vue en élévation et en coupe montrant les éléments précités, assemblés.
Other details and advantages of the invention will emerge from the description which will be given below of a racket handle according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached drawing.
  • Figure 1 is an exploded view in elevation showing the components of the end of the handle according to the invention.
  • Figure 2 is an elevational view in section showing the aforementioned elements, assembled.

La poignée de raquette 1 selon les figures comporte un noyau 2 sur l'extrémité duquel se glisse un embout 3 qui comporte une partie 4 qui entoure l'extrémité du noyau 2 et une partie 5 qui, en position d'utilisation, déborde de l'extrémité de la poignée. Ces deux parties 4 et 5 sont séparées par une saillie périphérique 6 qui détermine l'endroit jusqu'où l'embout 3 est noyé dans la matière synthétique 7 qui entoure également le noyau 2 de la poignée.The racket handle 1 according to the figures comprises a core 2 on the end of which slides a tip 3 which comprises a part 4 which surrounds the end of the core 2 and a part 5 which, in the position of use, projects beyond the end of the handle. These two parts 4 and 5 are separated by a peripheral projection 6 which determines the place up to which the end piece 3 is embedded in the synthetic material 7 which also surrounds the core 2 of the handle.

La partie 4 de l'embout 3 s'étend en oblique et vers l'extérieur en direction de la saillie périphérique 6. Cette saillie périphérique 6 se situe à hauteur d'une section de plus grande diamètre qui permet d'obtenir une poignée qui offre une prise en main ou "grip" particulièrement favorable.The part 4 of the end piece 3 extends obliquely and outwards in the direction of the peripheral projection 6. This peripheral projection 6 is located at the height of a section of larger diameter which makes it possible to obtain a handle which offers a particularly favorable grip or "grip".

L'embout, qui présente une série de fentes 8 s'étendant selon des plans qui coïncident avec l'axe géométrique de la poignée, est constitué d'une matière souple telle que du caoutchouc souple ou synthétique ou un élastomère. Au centre de l'embout 3 est prévue une cavité axiale 9 comportant une partie cylindrique centrale 10 qui présente intérieurement des creusures longitudinales 11 dia­ métralement opposées pour recevoir un élément de poids interchan­geable 12, lui-même muni de deux tétons 13 qui coopèrent avec les creusures longitudinales 11 prévues dans la partie cylindrique centrale 10 à la manière d'un assemblage à baïonnette. La partie cylindrique centrale 10 de l'embout 3 pénètre, à cet effet, dans une cavité de section correspondante 14 prévue dans l'axe de la poignée, à l'extré­mité de celle-ci.The tip, which has a series of slots 8 extending along planes which coincide with the geometric axis of the handle, is made of a flexible material such as flexible or synthetic rubber or an elastomer. In the center of the end piece 3 is provided an axial cavity 9 comprising a central cylindrical part 10 which internally has longitudinal recesses 11 dia metrically opposite to receive an interchangeable weight element 12, itself provided with two pins 13 which cooperate with the longitudinal recesses 11 provided in the central cylindrical part 10 in the manner of a bayonet connection. The central cylindrical part 10 of the nozzle 3 penetrates, for this purpose, into a cavity of corresponding section 14 provided in the axis of the handle, at the end of the latter.

Au fond de la cavité 14 est disposée une pièce en matière élastique 15 à effet de ressort, par exemple en caoutchouc, grâce à laquelle l'élément 12 est repoussé par ses tétons contre le bord libre de la partie cylindrique centrale 10.At the bottom of the cavity 14 is disposed a piece of elastic material 15 with a spring effect, for example rubber, by means of which the element 12 is pushed back by its pins against the free edge of the central cylindrical part 10.

Chaque élément de poids interchangeable possède un poids différent et il est donc possible de modifier les caractéristiques techniques de la raquette grâce à la simplicité du système de montage de ces éléments.Each interchangeable weight element has a different weight and it is therefore possible to modify the technical characteristics of the racket thanks to the simplicity of the assembly system for these elements.

La rotation de l'élément de poids inter­changeable est obtenue grâce à la présence d'une fente 16′ dans la partie extérieure de la tête 16 de l'élément.The rotation of the interchangeable weight element is obtained thanks to the presence of a slot 16 ′ in the external part of the head 16 of the element.

Il est entendu que l'invention n'est pas limitée à la forme d'exécution décrite et que bien des modifications pourraient y être apportées sans sortir du cadre de la présente demande de brevet.It is understood that the invention is not limited to the embodiment described and that many modifications could be made to it without departing from the scope of this patent application.
