Abstract

La présente invention concerne un putter. Plus particulièrement, l'invention concerne un putter qui permet d'effectuer un putt en direction d'un trou sur un green en donnant l'impression de n'utiliser qu'un seul doigt. Le putter de l'invention permet d'effectuer un putt précis au moyen d'une unité réfléchissante située sur la tige du putter et permet au golfeur d'effectuer un putt sur une pente progressive/forte sur un green ainsi que sur une surface plate. Le putter de l'invention est équipé d'une tige et d'un manche. Une poignée est positionnée sur la partie supérieure de la tige et une tête de club est située sur la partie inférieure de la tige. Une face d'impact et une ligne centrale sont formées dans la tête du club. Le manche qui est raccordé à la tige comprend une partie destinée à être saisie par les mains du golfeur pour tenir le club, et un trou d'insertion de doigt sur la surface qui adhère fortement à la tige. Le putter selon l'invention permet au golfeur de faciliter la concentration physique et nerveuse nécessaires à la pratique d'un putt et d'effectuer un putt avec un doigt à l'aide d'une ligne de référence indiquant les angles du trou et de la balle sur une surface plate et une pente progressive/forte. Le putter de l'invention permet également de faire coïncider la première ligne de support d'une balle de golf avec une ligne horizontale et une ligne d'inclinaison sur l'unité réfléchissante et permet au golfeur d'effectuer un putt au moyen de l'aide apportée de façon à augmenter son taux de réussite lors de la pratique d'un putt y compris sur un green présentant une surface convexe.
