Golf club with improved weighting

Abstract

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.

What is claimed is: 
     
         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.
