Gravitational force perception cylindrical configuration (making from now on timing bar,) internal golf crab.

摘要

PROBLEM TO BE SOLVED: To improve stability by down-swinging a club with a fixed timing.;SOLUTION: By caring about the gravity by falling of a timing bars incorporated in the club at the time of changing from back swing, a timing of down swinging is obtained, thereby golf swing is stabilized. By analyzing data with a timing bar with a sensor, swing is improved and a proper club is selected.;COPYRIGHT: (C)2003,JPO
