Golf club

Abstract

A golf club permits a swing that does less harm to the body of a golfer and, in particular, to his vertebral column. The club has a shaft length that, in an embodiment of the invention, is longer than a standard shaft length by more than 2 inches, and a lie angle that more acute than a standard lie angle.

What is claimed is:  
     
         1 . A golf club in the iron category, having a head with design parameters, including a lie angle, which are standardized as a function of the category number, and a shaft with a shaft length which has a standard shaft length assigned to it as a function of the category number, wherein the shaft length is longer than the standard shaft length by more than 2 inches (5.08 cm), and wherein the lie angle is more acute than the standard lie angle.  
     
     
         2 . The golf club as claimed in  claim 1 , wherein the lie angle is more acute than the standard lie angle by 2° to 10°.  
     
     
         3 . The golf club as claimed in either of the preceding claims, wherein the lie angle is more acute than the standard lie angle by 5° to 8°.  
     
     
         4 . The golf club as claimed in one of the preceding claims, wherein the shaft length is longer than the standard shaft length by 3″ to 8″.  
     
     
         5 . The golf club as claimed in one of the preceding claims, wherein the shaft length is longer than the standard shaft length by 5″ to 6″.  
     
     
         6 . The golf club as claimed in one of the preceding claims, wherein the inversion angle is less than 180°.  
     
     
         7 . The golf club as claimed in one of the preceding claims, wherein the bottom edge of the club head is convexly curved about an axis inclined in the shot direction.
