<p><P>PROBLEM TO BE SOLVED: To provide a golf club set with constant centrifugal force. <P>SOLUTION: The relation between the length r<SB>n</SB>of a shaft and the weight m<SB>n</SB>of a head of a golf club is preferably prepared to be always r<SB>1</SB>m<SB>1</SB>=r<SB>2</SB>m<SB>2</SB>=r<SB>3</SB>m<SB>3</SB>= to =r<SB>n</SB>m<SB>n</SB>=constant. The head is preferably formed as small as possible in streamline shape either wood or metal to avoid wind resistance to the utmost, and each number is unified in the same shape so as to minimize the size difference. Only the loft may be changed. Further, the shaft is preferably not made of a reinforced aluminum pipe but made of a lucid rod if possible. If it is necessary to increase strength, it is preferable to use an angular rod such as a hexagonal rod. If it is troubled because of whistling sound or the like, a cylinder of suitable material can be put over it, and also a grip part may be integrally formed. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
