SWING ANALYZER
First Claim
Patent Images
1. A swing analyzer capable of outputting information that can be used for analyzing a swing of a user, comprising:
- first and second acceleration sensors provided on a swing member swung by a user and having a longitudinal direction, spaced apart by a distance in said longitudinal direction;
a calculating unit capable of calculating speed of a portion as an object of measurement of said swing member, positioned apart from said first and second acceleration sensors in said longitudinal direction; and
a display unit displaying a result of calculation;
whereinassuming that said swing member is in circular motion during a swing, said calculating unit calculates a virtual speed at said portion as the object of measurement based on the distance between said first and second acceleration sensors, distance between said first acceleration sensor and said portion as the object of measurement and outputs from said first and second acceleration sensors, calculates speed of said portion as the object of measurement utilizing said virtual speed, and displays the speed on said display unit.

Abstract
A calculating unit of a swing analyzer calculates, assuming that a golf club is in a uniform circular motion about a virtual center of rotation 0 during a swing, a virtual speed Vh at a central point R of a golf club head, based on a distance between first and second acceleration sensors, a distance between the first acceleration sensor and the central point R of a golf club head and outputs from the first and second acceleration sensors, and calculates the speed of central point R of a golf club head utilizing the virtual speed Vh.
