Golf club with improved weight distribution
View Patent ↗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.
1. A method of adjusting a golf club comprising:
adjusting a center of gravity of a weight adjustment member by locking a heavy weighted portion of said weight adjustment member at a preferred location on a connection rod of said weight adjustment member;
installing said weight adjustment member into a grip end of said golf club;
wherein said golf club comprises a shaft and a grip located at said grip end of said shaft and wherein said weight adjustment member comprises a flange, a locking bolt, and a rubber stopper;
wherein installing said weight adjustment member comprises inserting said weight adjustment member inside said shaft until a portion of said grip resides in an annular channel formed in said flange, and tightening said locking bolt, expanding said rubber stopper against said shaft, securing said weight adjustment member to said golf club;
adjusting a face angle of said golf club via an adjustable hosel mechanism;
wherein said weight adjustment member has a mass (Mass wam ) based on the relationship

,
having a Factor of Adjustment (F) between about 10 to about 30;
wherein said shaft has a shaft mass of between about 60 grams to about 100 grams; and
wherein said grip has a mass of about 45 grams to about 55 grams.
2. The method of adjusting a golf club of claim 1 , wherein said heavy weighted portion comprises a majority of said weight adjustment member.
3. The method of adjusting a golf club of claim 2 , wherein said weight adjustment member comprises a mass between about 15 to 100 grams.
4. The method of adjusting a golf club of claim 3 , wherein said weight adjustment member comprises a mass between about 25 to 75 grams.
5. The method of adjusting a golf club of claim 4 , wherein said weight adjustment member comprises a mass between about 35 to 50 grams.
6. The method of adjusting a golf club of claim 2 , wherein adjusting a center of gravity of said weight adjustment member comprises adjusting the location of said heavy weighted portion along said weight adjustment member, wherein said heavy weighted portion is adjusted relative to a grip fulcrum located 4 inches away from a butt end of said golf club according to the relationship

wherein said distance (d 2 ) is the distance from the center of gravity of said heavy weighted portion from said grip fulcrum, wherein Mass hwp is the mass of said heavy weighted portion, and wherein R is a ratio of swingweights.
7. The method of adjusting a golf club of claim 6 , wherein said ratio of swingweights (R) is approximately 0.3.
8. The method of adjusting a golf club of claim 6 , wherein said distance (d 2 ) comprises a distance between 0 and 3.5 inches.
9. The method of adjusting a golf club of claim 8 , wherein said distance (d 2 ) comprises a distance between 0 and 3.0 inches.
10. The method of adjusting a golf club of claim 9 , wherein said distance (d 2 ) comprises a distance between 0 and 2.5 inches.
