SWING ANALYZER AND GOLF CLUB SHAFT SELECTING SYSTEM
First Claim
1. A swing analyzer capable of outputting information usable for analyzing a swing of a user swinging a golf club including a shaft extending in a longitudinal direction and a head portion provided at one end of said shaft, comprising:
- a toe down strain gauge provided on the shaft of said golf club and capable of measuring strain in toe down direction of said shaft;
a built-in processing unit calculating an expected bending point value corresponding to a position of bending point of said shaft; and
a built-in display unit capable of displaying an output value from said built-in processing unit;
whereinsaid built-in processing unit calculates said expected bending point value based on a measured value of said toe down strain gauge at a first time point during a swing of the user and on a measured value of said toe down strain gauge at a second time point preceding said first time point;
said built-in processing unit stores in advance conversion data for converting said expected bending point value to recommended kick point output value;
said recommended kick point output value is an output value representing the expected bending point value of said shaft; and
said built-in processing unit outputs said recommended kick point output value corresponding to said calculated expected bending point value to said built-in display unit.

Abstract
A measuring device includes a strain gauge, a processing unit calculating an expected bending point value corresponding to a bending point position, and a display unit capable of displaying an output value from the processing unit. The processing unit calculates the expected bending point value based on a measured value of strain gauge at a first time point during a swing of the user and a measured value of strain gauge at a second time point closer to an impact time point than the first time point. The processing unit stores in advance conversion data for converting the expected bending point value to recommended kick point output value indicating kick point, and the processing unit outputs the recommended kick point output value corresponding to the calculated expected bending point value to the display unit.

5. A swing analyzer capable of outputting information usable for analyzing a swing of a user swinging a golf club including a shaft extending in a longitudinal direction and a head portion provided at one end of said shaft, comprising:
-
first and second acceleration sensors provided on said shaft spaced apart from each other in said longitudinal direction; a built-in processing unit capable of calculating a radius of rotation of said shaft based on outputs from said first and second acceleration sensors, and a built-in display unit displaying a result of calculation by said built-in processing unit;
whereinsaid built-in processing unit stores conversion data for converting the radius of rotation of said shaft to a cock angle of the user; said built-in processing unit calculates cock angle of the user from calculated speed of said head portion; and said built-in display unit displays said calculated cock angle.
