  • Patent number: 9881137
    Abstract: Provided is a fitting apparatus that accurately and objectively determines an optimal swingability index, which is a swingability index of a golf club suited to a golfer. The fitting apparatus is provided with an acquisition unit, a calculation unit, and a determination unit. The acquisition unit acquires a measurement value obtained by measuring a swing action of a test club by the golfer with a measurement device. The calculation unit calculates a swing index indicating a feature amount of the swing action, based on the measurement value. The determination unit determines the optimal swingability index, according to a magnitude of the swing index.

  • Patent number: 9630066
    Abstract: A fitting method, of a shaft of a golf club, for selecting a shaft having a torque matching a golfer based on a swing of the golfer. The method includes the steps of obtaining measurement values from a sensor attached to a grip of the golf club and capable of measuring angular velocities about three axes when a golf ball is hit by the golf club; obtaining a predetermined index value for the angular velocities quantified from the measurement values; and selecting a shaft matching the golfer from among multiple shafts whose torques have been measured in advance, based on a relationship established through test-hitting performed in advance between the index value and a torque of a shaft.

  • Publication number: 20160354654
    Abstract: Provided is a golf club head that includes a face portion for hitting a ball. The face portion has a thick portion that includes a face center, and a peripheral portion that is thinner than the thick portion and surrounds the thick portion. The thick portion extends along a central axis line, and has a recessed portion on at least one side of the central axis line so that a central region of the thick portion along the central axis line is recessed more toward the central axis line than parts of the thick portion on two sides of the central region along the central axis line. Note that the central axis line extends in a top-sole direction or in a direction inclined from a toe side toward a heel side along a direction from a sole side toward a top side.

  • Patent number: 9297729
    Abstract: An evaluation method for hit feeling of a sport implement according to the present invention includes an acceleration measurement step for measuring acceleration of a sport hitting tool 4 and a data analysis step for analyzing data obtained in the measurement. In the data analysis step, an amount of change in acceleration in a first cycle of vibration after hitting is calculated. The evaluation method evaluates hit feeling to be felt by a person, using the amount of change in the acceleration. Preferably, in the data analysis step, an amount of change in acceleration in the first cycle of predetermined time is calculated. The predetermined time is within 1.5 msec from the time of hitting. Preferably, the sport hitting tool 4 has the hitting section detachably attached to a shaft section.
