  • the present invention relates to a golf club that further improves flight distance, improves flight distance, and improves ball hitting direction stability by eliminating fogging phenomena and changing the design of the accompanying face surface and the like.
  • Conventional head clubs are not limited to metal heads, but as shown by the dotted line in Fig. 1, the head shape gradually expands from the shaft side to the toe side, and the center of gravity of the head is headed. It is assumed that it is located on the top side from the center of the projection plane, and that the head speed at impact is improved.

  • the region and the shaft side region have a shape that is unevenly distributed from the almost symmetrical shape to the shaft region side as the capacity distribution. Therefore, the center of gravity of the head is G. Not only moves from the shaft side to the shaft side G, but also increases the shaft side volume distribution, A weight distribution that is excellent in suppressing the toe side fogging phenomenon and the shaft side shrinkage phenomenon at the time of impact will be completed.

Abstract

Club de golf destiné à améliorer la distance de vol d'une balle grâce à l'élimination du phénomène de tirage sur le manche se produisant en réaction au phénomène de pointe affaissée susceptible de se produire particulièrement avec un joueur entraîné aimant avoir une grande vitesse de la tête et voulant améliorer ladite vitesse de la tête, ledit club de golf étant également destiné à améliorer la stabilité directionnelle d'une balle frappée, grâce à l'élimination du phénomène de pointe affaissée et grâce au changement de la conception dudit club de golf notamment au niveau de sa face. Le club de golf proposé se caractérise en ce que le centre de gravité de sa tête est déplacé de l'extrémité de la pointe vers l'extrémité du manche, la forme de la tête étant modifiée de façon que son volume décroisse d'une certaine valeur à l'extrémité de la pointe, sur son côté arrière, et que ledit volume augmente à l'extrémité du manche, sur le côté arrière, d'une valeur égale à celle du décroissement du volume de la tête, ce qui réduit le rayon de rotation de la tête autour d'une ligne verticale, ladite ligne servant d'axe de rotation lorsque le club de golf est suspendu par l'extrémité supérieure de son manche. En outre, dans un club métal-bois une tête est pourvue d'une face qui comprend une face sphérique formée de façon que la courbe dans le sens de la largeur transversale devienne pratiquement égale à celle de la courbe dans le sens de la largeur verticale. En outre, dans un club en fer, la forme du dos de la partie faciale est obtenue par le fait que l'axe central a de la garniture se trouvant au-dessus est mis dans une position dans laquelle il traverse, dans le sens transversal, et l'augmentation de l'épaisseur du dos du coup est obtenue par déplacement d'une partie du poids à l'extrémité de la pointe.
