Abstract
A golf club with improved weight distribution is disclosed herein. More specifically, the present invention discloses a golf club with a lightweight shaft allowing the golfer to achieve higher swing speed, while shifting the weight savings of the shaft to a grip portion of the club; counterbalancing some of the undesirable performance characteristics associated with a lightweight shaft.
Claims20
A golf club comprising:
- a club head located at a distal end of said golf club;
- a grip located at a proximal end of said golf club;
- a shaft juxtaposed between said club head and said grip, connecting said club head to said grip;
- and
- a weight adjustment member attached to a proximal end of said grip,
- a flange at a proximal end of said weight adjustment member, said flange comprising an annular channel, a portion of said grip residing within said annular channel;
- wherein said club head has a club head mass of between about 170 grams to about 225 grams and said grip has a grip mass of between about 25 grams to 60 grams with said grip having a grip density (Densitygrip) of between about 2.0 grams/inch and about 5.0 grams/inch;
- wherein said shaft has a shaft mass of less than about 40% of said club head mass yielding a shaft density (Densityshaft) of between about 1.0 grams/inch and about 2.0 grams/inch, and
- wherein said weight adjustment member has a mass (Masswam) determined based on the relationship
