Abstract

La présente invention concerne un manche conçu comme si le manche était relié au point idéal d'une tête, de telle sorte qu'il est possible de toujours frapper une balle au point idéal en éliminant la fluidité de la tête pendant le swing et l'impact, en améliorant ainsi la frappe de balle et en maintenant un rythme de swing, un tempo et une synchronisation stables. Le manche comprend : un corps de manche de forme tubulaire présentant un côté inférieur dont le diamètre est petit et inférieur au diamètre d'un côté supérieur de celui-ci ; une partie d'extrémité de pointe couplée à un col de liaison sur le côté talon de la tête d'un club de golf sur le côté inférieur du corps de manche ; et une partie d'extrémité d'embout à laquelle une poignée que l'utilisateur peut tenir est couplée au niveau du côté supérieur du corps de manche, le manche comprenant : une partie de changement de ligne d'axe placée au niveau d'un point d'inertie de rotation, qui est de 14 pouces (35,36 cm) de la partie d'extrémité d'embout du corps de manche à la partie d'extrémité de pointe ; et une ligne d'axe de liaison le long de laquelle le centre de l'axe du côté inférieur du manche par rapport à la partie de changement de ligne d'axe coïncide avec un col de liaison de la tête, et une ligne d'axe de swing le long de laquelle le centre d'axe de la poignée dans le côté supérieur de l'unité de conversion de ligne d'axe coïncide avec le point idéal (SP) de la tête.
