Abstract
Description
Peu de sports sans doute, pour être pratiqués, entraînent l'utilisation d'autant de matériels divers que le Colf. Les " Clubs " en particulier, qui sont les outils essentiels de ce jeu, doivent avoir des qualités métrologiques et mécaniques toutes particulières et variant d'un Club à l'autre, puisque chaque Club est adapté à une traJectoire spécifique et voulue par le joueur, tant en Seltz < , 'en 'ou Lt, e t 'n rotation de la btiile. Undoubtedly few sports, to be practiced, involve the use of as many diverse materials as the Colf. The "Clubs" in particular, which are the essential tools of this game, must have very specific metrological and mechanical qualities and vary from one Club to another, since each Club is adapted to a specific trajectory and desired by the player , both in Seltz <, 'in' or Lt, and 'n rotation of the building.
Ainsi, la tête d'un Club joue un rôle essentiel dans cette trajectoire, et c'est ce qui explique que pour jouer, il faut une " série " comprenant un ensemble de douze à quinze Clubs (9 fers + 3 bois à 9 fers + 6 bois) appartenant tous à la fois à l'une des cinq classes d'élasticité du manche définies suivant l'échelle de " Kenneth Smith " et désignées respectivement par L (Ladies), A (Flexible), R (Médium),
S (Stiff, c'est à dire raide), E (Extra stiff, c'est à dire Extra raide). La face de chaque " Tête " des 12 Clubs est orientée par rapport à l'axe du manche du Club selon un angle qui donnera à la balle lors de l'impact, son angle de site.Cet angle est baptisé " angle de loft " par les Anglophones, et plus il est ouvert, moins la trajectoire de la balle sera tendue. I1 convient de remarquer que si l'angle de site est donné par l'angle de la tête du Club, la route suivie par la balle est celle que doit choisir le joueur. Mais on sait que le point d'impact de la tête du
Club sur la balle n'est pas situé dans l'axe du manche. I1 en résulte un couple de torsion s'exerçant sur le manche. I1 est clair alors que si ce manche est fabriqué de matériaux contrariant mal ce couple, la trajectoire de la balle sera perturbée, ce qui est un inconvénient redhibitoire dans ce sport de très grande précision.Thus, the head of a Club plays an essential role in this trajectory, and this explains why to play, you need a "series" comprising a set of twelve to fifteen Clubs (9 irons + 3 woods with 9 irons + 6 woods) all belonging to one of the five elasticity classes of the handle defined according to the "Kenneth Smith" scale and designated respectively by L (Ladies), A (Flexible), R (Medium),
S (Stiff, ie stiff), E (Extra stiff, ie Extra stiff). The face of each "Head" of the 12 Clubs is oriented relative to the axis of the Club handle at an angle which will give the ball, upon impact, its elevation angle. This angle is called "loft angle" by English speakers, and the more it is open, the less the trajectory of the ball will be tense. It should be noted that if the elevation angle is given by the angle of the head of the Club, the course followed by the ball is that which the player must choose. But we know that the point of impact of the head of the
Club on the ball is not located in the axis of the handle. I1 results in a torque exerted on the handle. I1 is clear then that if this handle is made of materials opposing badly this couple, the trajectory of the ball will be disturbed, which is a prohibitive disadvantage in this sport of very high precision.
On sait aussi qu'un manche de Club souple et léger (Ladies @ " L ", par exemple, fa- briqué en matériaux composites (fibres de carbone associées à des résines epoxy par exemple) dont les caractéristiques de légèreté sont très avantageuses, donne souvent des trajectoires " slicées " comme disent les spécialistes anglophones, c'est à dire que la route suivie par la balle sera déviée de quelques degrés dûs à la déformation circulaire du manche lors de l'exercice du couple de torsion. We also know that a flexible and light Club handle (Ladies &Commat; "L", for example, made of composite materials (carbon fibers associated with epoxy resins for example) whose lightness characteristics are very advantageous, Often gives "sliced" trajectories as say the English-speaking specialists, that is to say that the route followed by the ball will be deviated by a few degrees due to the circular deformation of the handle during the exercise of the torque.
Les dispositifs selon l'invention, permettent de contrôler le couple de torsion du manche fabriqué à partir de fibres de synthèse associées à des résines en enroulant autour du manche une hélice de fibres de synthèse (carbone, verre ou polyamides aromatiques) associées à des résines venant adhérer au manche de telle façon que le sens de l'enroulement hélicoïdal (sens trigonométrique ou inverse pour les joueurs gauchers) vienne contrarier le couple créé lors de l'impact.The devices according to the invention make it possible to control the torque of the handle made from synthetic fibers associated with resins by winding around the handle a helix of synthetic fibers (carbon, glass or aromatic polyamides) associated with resins coming to adhere to the handle in such a way that the direction of the helical winding (trigonometric or reverse direction for left-handed players) comes to thwart the torque created during the impact.
Pour bien faire comprendre l'invention, on en décrira ci-après des exemples d'exécution sans caractère limitatif, en référence au dessin annexé dans lequel la figure 1 est une coupe de la tête (2) et du manche (1) du Club au niveau du centre de la balle de golf (3). On observe que lors de l'impact la force " f " engendre par le bras de levier " d " un couple de torsion T qui modifiera la route de la balle de degrés.To better understand the invention, there will be described below examples of execution without limitation, with reference to the accompanying drawing in which Figure 1 is a section of the head (2) and the handle (1) of the Club at the center of the golf ball (3). It is observed that during the impact the force "f" generates by the lever arm "a torque T which will modify the course of the ball by degrees.
La figure 3 est une vue en perspective de la tête (2) du Club fixée sur le manche (1). On observe sur les figures 1 et 2 qu'il s'agit d'un Club de golf destiné à un joueur droitier. Ainsi le couple engendré par la force " su " s'exerce dans le sens trigonométrique. A l'inverse, s'il s'agissait d'un Club à l'usage d'un gaucher, le couple de torsION s'exercerait dans le sens inverse.Figure 3 is a perspective view of the head (2) of the Club attached to the handle (1). It can be seen in Figures 1 and 2 that it is a Golf Club intended for a right-handed player. Thus the couple generated by the force "su" is exerted in the trigonometric direction. Conversely, if it were a club for the use of a left-handed person, the torque would be exerted in the opposite direction.
La figure 3 est une vue du Club dans laquelle, autour du manche (1), a été enroulée une hélice (4) de fibres de synthèse associées à des résines.Figure 3 is a view of the Club in which, around the handle (1), has been wound a helix (4) of synthetic fibers associated with resins.
Le sens de l'enroulement (4) est inverse au sens du couple T afin de contrarier celui-ci.The direction of the winding (4) is opposite to the direction of the torque T in order to counteract it.
Le pas (p) et l'angle de l'enroulement sont variables selon le profil et la nature des matériaux constituant le manche. En effet, le manche peut être cylindrique ou conique et plus ou moins souple, de telle façon que la résistance qu'il oppose au couple est plus ou moins importante. Par ailleurs, plus on s'éloigne de la tête en montant vers le sommet du Club, moins il est nécessaire de contrarier le couple qui lest naturellement par les matériaux qui constituent le manche. Ainsi au niveau de la poignée du manche, il peut n'être plus nécessaire de réaliser cet enroulement hélicoïdal. The pitch (p) and the angle of the winding are variable depending on the profile and the nature of the materials constituting the handle. Indeed, the handle can be cylindrical or conical and more or less flexible, so that the resistance it opposes to the torque is more or less important. In addition, the farther you go from your head while going up towards the top of the Club, the less it is necessary to counteract the couple which naturally ballasts with the materials which constitute the handle. Thus at the handle of the handle, it may no longer be necessary to carry out this helical winding.
Selon une autre variante, on peut réaliser deux enroulements dans des sens oppose qui viendront donc se croiser en se superposant, permettant ainsi de réaliser ur manche de Club indifféremment destiné à un gaucher ou à un droitier. According to another variant, it is possible to make two windings in opposite directions which will therefore intersect and overlap, thus making it possible to produce a Club handle either for a left-handed or a right-handed person.
