Sensor unit, sensor set, sports equipment, and mounting method of sensor unit

Abstract

A sensor unit is mounted on a golf club which is one of sports equipments, and detects an inertial amount generated by a swing. In the sensor unit, a Z-axis serving as a detection axis of the inertial amount generated along a direction orthogonal to a surface located on the golf club side when the sensor unit is mounted on the golf club is set to extend along a direction S of the swing.

What is claimed is: 
     
         1 . A sensor unit which is mounted on a sports equipment so as to detect an inertial amount generated by a swing,
 wherein a detection axis of the inertial amount generated along a direction orthogonal to a surface located on the sports equipment side when the sensor unit is mounted on the sports equipment is set to extend along a direction of the swing.   
     
     
         2 . The sensor unit according to  claim 1 ,
 wherein the sensor unit has multiple detection axes, and   wherein one of the detection axes is set to extend along the direction of the swing, and the other one of the detection axes is set to extend along an extending direction of a shaft of the sports equipment.   
     
     
         3 . A sensor unit which is mounted on a sports equipment so as to detect an inertial amount generated by a swing,
 wherein a surface located on the sports equipment side when the sensor unit is mounted on the sports equipment is set to be a surface orthogonal to a direction of the swing.   
     
     
         4 . A sensor unit which is mounted on a sports equipment so as to detect an inertial amount generated by a swing,
 wherein a detection axis of the inertial amount generated along a direction orthogonal to a surface located on the sports equipment side when the sensor unit is mounted on the sports equipment is set to extend along a direction orthogonal to a hitting surface of the sports equipment.   
     
     
         5 . The sensor unit according to  claim 4 ,
 wherein the sensor unit has multiple detection axes, and   wherein one of the detection axes is set to extend along the direction orthogonal to the hitting surface of the sports equipment, and the other one of the detection axes is set to extend along an extending direction of a shaft of the sports equipment.   
     
     
         6 . A sensor set comprising:
 the sensor unit according to  claim 1 ; and   a holding tool for mounting the sensor unit on the sports equipment.   
     
     
         7 . A sensor set comprising:
 the sensor unit according to  claim 2 ; and   a holding tool for mounting the sensor unit on the sports equipment.   
     
     
         8 . A sensor set comprising:
 the sensor unit according to  claim 3 ; and   a holding tool for mounting the sensor unit on the sports equipment.   
     
     
         9 . A sensor set comprising:
 the sensor unit according to  claim 4 ; and   a holding tool for mounting the sensor unit on the sports equipment.   
     
     
         10 . A sensor set comprising:
 the sensor unit according to  claim 5 ; and   a holding tool for mounting the sensor unit on the sports equipment.   
     
     
         11 . The sensor unit according to  claim 4  which has a portion to be fitted to a holding tool, and which is mounted on the sports equipment by the portion and the holding tool being fitted to each other. 
     
     
         12 . A sports equipment on which the sensor unit according to  claim 1  is mounted. 
     
     
         13 . A sports equipment on which the sensor unit according to  claim 3  is mounted. 
     
     
         14 . A sports equipment on which the sensor unit according to  claim 4  is mounted.
