GOLF CLUB WITH IMPROVED WEIGHTING
A plurality of two or more golf clubs with improved weighting characteristics is disclosed. More specifically, the present invention discloses a specific relationship between the mass M club of the golf club and the length L club to help improve the performance of the golf club.
1 . 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; and
a shaft, juxtaposed between said club head and said grip, connecting said club head to said grip;
wherein a mass M club of said golf club decreases with an increase in a length L club of said golf club in accordance with the relationship, M club ≧−20.691 L club +1201.5.
2 . The golf club of claim 1 , wherein said shaft is stepped.
3 . The golf club of claim 1 , wherein a mass M shaft of said shaft decreases with an increase in a length L shaft of said shaft in accordance with the relationship, M shaft ≧−6 L shaft +347.
4 . The golf club of claim 3 , wherein said length of said golf club L club is between 32 inches and 48 inches.
5 . A plurality of golf clubs comprising:
a first golf club having a length L club of greater than about 38 inches having a first mass,
a second golf club having a length L club of between about 36 inches to about 38 inches having a second mass, and
a third golf club having a length L club of less than about 36 inches having a third mass,
wherein said first mass is less than said second mass and said second mass is less than said third mass; and
wherein said first, second, and third golf club all have individual shafts that have a mass that satisfies the equation M shaft ≧−6 L shaft +347.
6 . The plurality of golf clubs of claim 5 , wherein said first mass is less than about 415 grams.
7 . The plurality of golf clubs of claim 6 , wherein said second mass is between about 415 grams and about 446 grams.
8 . The plurality of golf clubs of claim 7 , wherein said third mass is greater than about 446 grams.
9 . The plurality of golf clubs of claim 5 , wherein said first mass, said second mass, and said third mass are all a function of said length of said first, second, or third golf club in accordance with the relationship, M club ≧−20.691 L club +1201.5.
10 . The plurality of golf clubs of claim 9 , said shaft is stepped.
11 . The plurality of golf clubs of claim 9 , wherein said first golf club further comprises a first shaft, said first shaft has 15 sections; wherein each section has a decrease in outer diameter.
