Abstract:
A golf club measuring apparatus comprising:a base having a flat top reference surface; a club-holding assembly pivotally mounted to the base above the flat top reference surface of the base for pivoting movement about a pivot axis; club-gripping means for releasably holding a club shaft, including a pair of grooved frames which are provided with v-shaped grooves, faced with each other, and are arranged at least at two positions on the club-holding assembly, and having a reference line passing through the centers of the v-shaped grooves and obliquely intersecting with the reference surface of the base; a Y-direction slide plate provided on the base and being slidable in a direction (Y direction) which is parallel to the line of intersection between a virtual vertical plane including the reference line and the reference plane; an X-direction slide plate detachably arranged on the Y-direction slide plate and being movable in a direction (X direction) which is orthogonal to the sliding direction of the Y-direction slide plate; a first pole standing upright on the X-direction slide plate; a club face regulator provided on the first pole, being vertically movable, and having a reference line parallel to the Y-direction; a second pole standing upright on the X-direction slide plate; a first protractor provided on the second pole for measuring a loft angle of the club whose face orientation is regulated by the club face regulator; a second protractor provided with a scale on an circular surface around the pivot axis and used for measuring an angle of inclination of the reference line with respect to the reference surface; and a scale for measuring a distance between the X-direction slide plate and the virtual vertical plane on the plane which is parallel to the X direction of the Y-direction slide plate.
