Title: Method for measuring deflection characteristic of golf club shaft
Inventor: MATSUMOTO AKIO
IPC: A63B102/32
Filed: 1992-09-28
Abstract: PURPOSE:To intuitively recognize the microdistribution in the easily bendable part in a longitudinal direction by fixing a grip side, applying load to a free end to deflect a club shaft, measuring the displacement quantity from the neutral position of a neutral axis to determine the approximate curve of a deflection curve and determining a curvature curve from the approximate deflection curve. CONSTITUTION:The grip G of the club shaft 11 is fixed and the load W is acted on the free end side to deflect the club shaft 11. The displacement from the neutral axis x of the club shaft 11 in the load state is measured in the longitudinal direction and the approximate curve of the deflection curve of the club shaft 11 in the load state is determined from the actually measured result. The curvature curve indicating the change in the longitudinal direction of the club shaft 11 is then determined from the approximate deflection curve. As a result, the deflection characteristic of the club shaft and particularly where the microscopically observed easily bendable part exists is intuitively measured.
