Abstract

Golf clubs are made with head and shaft as an integral item made of the same materials except the core of a large head on a club such as a driver may comprise an insert of different material, opt. denser than that used for the shaft and the surface of the head. Avoids the assembly and inherent weakness of a fastening between a club head and a separate shaft. Pref. the shaft and at least the external form of the head are produced by injection moulding using a plastic moulding material (unspecified) opt. contg. a filler of divided metal for increased mass and/or fibres for increased stiffness.

Description

La présente invention concerne la fabrication des clubs de golf et, de façon plus précise , les problèmes dûs au raccordement du manche et de la tête. The present invention relates to the manufacture of golf clubs and, more specifically, the problems due to the connection of the handle and the head.

La technique actuelle de fabrication des clubs de golf consiste en l'assemblage de deux sous-ensembles: la tête et le manche. Les matériaux utilisés pour chacun de ces sousensembles sont variés: on trouve des têtes en acier, en bois, en plastique ou en métal léger et des manches en acier, en bois ou en matériau synthétique. Mais de nombreux problèmes de fabrication et d'utilisation sont liés au fait qu'il faut assembler de façon solidaire la tête et le manche du club: en effet, pour le fabricant, il est nécessaire de prévoir un moyen de fixation du manche sur la tête, moyen qui est en général le collage du manche dans une douille prévue à cet effet et, pour l'utilisateur, il peut y avoir des nuisances pour son jeu, nuisances dues à un collage imparfait qui ne ferait pas co#ncider exactement l'axe du manche et l'axe de la douille. The current technique for manufacturing golf clubs consists of the assembly of two sub-assemblies: the head and the handle. The materials used for each of these sub-assemblies are varied: there are heads made of steel, wood, plastic or light metal and handles made of steel, wood or synthetic material. However, many manufacturing and use problems are linked to the fact that the head and the handle of the club must be joined together: in fact, for the manufacturer, it is necessary to provide a means of fixing the handle to the head, means which is in general the sticking of the handle in a socket provided for this purpose and, for the user, there can be nuisances for his game, nuisances due to an imperfect bonding which would not make coincide exactly l 'axis of the handle and the axis of the sleeve.

Le but de la présente invention consiste en un moyen de suppression de ces problèmes d'assemblage. The object of the present invention consists of a means of eliminating these assembly problems.

La présente invention consiste à fabriquer d'un seul tenant l'ensemble tête+manche du club. Pour cela on pourra, par exemple, employer un matériau synthétique moulable qui, tout en constituant le manche, vient envelopper - partiellement ou totalement - un noyau qui constitue une partie du volume de la tête du club. Le résultat est une jonction uniforme et continue du manche et de la tête du club. La présente invention a donc pour objet le produit nouveau que constitue un club de golf sans discontinuité entre le manche et la tête. The present invention consists in manufacturing in one piece the head + handle assembly of the club. For this we can, for example, use a moldable synthetic material which, while constituting the handle, comes to wrap - partially or totally - a core which constitutes part of the volume of the head of the club. The result is a uniform and continuous junction of the club's neck and head. The present invention therefore relates to the new product that constitutes a golf club without discontinuity between the handle and the head.

Les avantages de cette invention sont multiples: - la présente invention permet de choisir â volonté avant moulage, façonnage ou autre mode de fabrication, la forme, la masse et la matière du noyau, que celui-ci soit creux ou non. The advantages of this invention are manifold: the present invention makes it possible to choose at will before molding, shaping or other manufacturing method, the shape, the mass and the material of the core, whether the latter is hollow or not.

- la présente invention permet de positionner à volonté le centre de gravité de la tête du club. - The present invention allows to position at will the center of gravity of the head of the club.

- la présente invention permet de réaliser de façon continue la jonction manche-t#te des clubs de golf, ce qui présente un avantage pour le joueur de golf qui bénéficie de qualités nouvelles du club, notamment d'un apport de caractéristiques élastiques de la jonction uniforme du manche et de la tête. - The present invention makes it possible to continuously carry out the neck-t # te junction of golf clubs, which has an advantage for the golf player who benefits from new qualities of the club, in particular by providing elastic characteristics of the uniform junction of the handle and the head.

Cette liste, non limitative, montre l'intérsst de l'invention pour le jeu de golf.This non-exhaustive list shows the value of the invention for the game of golf.

Pour mieux faire comprendre l'objet de la présente invention on va décrire, à titre d'exemple purement illustratif et non limitatif, un club de golf réalisé selon l'invention et représenté sur le dessin annexé. To better understand the object of the present invention, a golf club produced according to the invention and shown in the accompanying drawing will be described, by way of purely illustrative and non-limiting example.

Sur ce dessin: - la figure 1 représente une jonction manche-tête telle que celles effectuées dans l'état de la technique. In this drawing: - Figure 1 shows a neck-head junction such as those made in the prior art.

- la figure 2 représente une jonction manche-tête d'un club de golf selon l'invention.- Figure 2 shows a neck-head junction of a golf club according to the invention.

Sur la figure 1 qui représente la solution classique de raccordement de la tête et du manche, on voit que la tête 1 comporte une douille 2 dans laquelle vient s'emboîter le manche 3
La figure 2 représente un club de golf selon l'invention: il s'agit ici d'un bois. On voit que la tête 1 est constituée d' un noyau 2 enveloppé par le matériau constitutif du manche 3 . Pour une meilleure clarté du dessin, on a représenté une tête de club tronquée. On voit sur le dessin que le noyau 2 occupe la majeure partie du volume de la tête 1 . On voit également que le noyau 2 est enveloppé de façon régulière par le matériau qui constitue le manche 3 .On voit aussi que le noyau 2 comporte un appendice 2a dont la section diminue vers le manche 3 , ceci étant un moyen permettant une bonne cohésion du manche 3 et de la tête 1 et un moyen de répartition des efforts que peut subir la jonction du manche 3 et de la tête 1 pendant le déroulement d'un coup de golf. Le matériau employé pour réaliser le manche 3 peut être une matière plastique chargée métalliquement afin de l'alourdir ou armée de fibres afin de la raidir; cette matière pouvant être moulée aisément, on peut réaliser le manche 3, la tête 1 et leur raccordement en surmoulant le noyau 2 en utilisant un procédé de surmoulage par injection par exemple. Le matériau utilisé pour le noyau 2 peut être plus lourd que celui qui est utile~ sé pour le manche 3, ceci afin de pouvoir équilibrer le club; il peut être, selon une autre variante, identique à celui qui constitue le manche 3, ceci afin de réaliser une tête 1 homo géne. Selon une autre variante, il peut ne pas y avoir de noyau 2 ou bien il peut y avoir un noyau 2 partiellement enve loppé. On voit donc que la caractéristique principale des clubs de golf selon l'invention est le fait qu'ils ne comportent ni douille ni embout pour fixer le manche â la tête mais qu'il y a une jonction continue du manche 3 et de la tête 1, lesquels constituent ainsi wne seule pièce. In FIG. 1 which represents the conventional solution for connecting the head and the handle, it can be seen that the head 1 has a socket 2 into which the handle 3 fits.
FIG. 2 represents a golf club according to the invention: it is here a wood. It can be seen that the head 1 consists of a core 2 enveloped by the material constituting the handle 3. For better clarity of the drawing, a truncated club head has been shown. We see in the drawing that the core 2 occupies most of the volume of the head 1. We also see that the core 2 is regularly enveloped by the material which constitutes the handle 3. We also see that the core 2 has an appendage 2a whose section decreases towards the handle 3, this being a means allowing good cohesion of the sleeve 3 and head 1 and a means of distributing the forces which the junction of handle 3 and head 1 can undergo during the course of a golf stroke. The material used to make the handle 3 can be a plastics material metallically loaded in order to weigh it down or reinforced with fibers in order to stiffen it; this material can be molded easily, the handle 3, the head 1 and their connection can be produced by overmolding the core 2 using an injection overmolding process for example. The material used for the core 2 can be heavier than that which is useful ~ se for the handle 3, this in order to be able to balance the club; it can be, according to another variant, identical to that which constitutes the handle 3, this in order to produce a homo gene head 1. According to another variant, there may not be a core 2 or there may be a partially enveloped core 2. It can therefore be seen that the main characteristic of golf clubs according to the invention is the fact that they do not have a socket or end piece for fixing the handle to the head but that there is a continuous junction of the handle 3 and of the head 1, which thus constitute a single piece.
