Description

Golf club-vertical axis and shaft position on the other side

(A) The vertical axis (4) of the other side of the club head is close to the vertical when viewed from the front, which makes it difficult for proper alignment and aiming.

(B) The shaft (SHAFT) 6 is located close to the inner point (HEEL) 9 of the club head, and when the ball is hitting, the CLUB FACE 2 is more likely to face outward than the target line 13.

(A) Make the golf ball, the target line 13 and the vertical axis 4 visible to the eye in a straight line.

(B) The golf club ride surface (2) is easily perpendicular to the target line (13) at the time of hitting.

※ Term Definition

(1) CENTROID of the other side: (3)

CENTROID of the clubhead (1) and the other side (FACE, 2) as seen from the front view.

(2) Vertical axis of the other side: (4)

The shortest axis in the longitudinal direction through the center of the other side in the front view. On the other side of the curved line, a straight line formed by points in the same direction as the target line 13 facing the center 3 (without considering the height direction).

(1) When viewed from the front of the club head, the vertical axis (4) of the other side is inclined at least 15 degrees from the vertical line to face the eye of the batter.

(2) Install the shaft close to the center of the other side (3).

(1) There is also a golfer who aligns the golf ball on the longitudinal axis (4) of the golf club surface, and puts the golf club behind the ball for direct aiming (AIM). . By aligning the vertical axis 4 of the other side toward the eye, it is easy to directly align and aim the golf club while standing at the hitting position.

This is because the vertical axis (including the sweet spot), the golf ball, and the goal line all appear on the same line.

(2) As the distance RW between the center of gravity 14 of the club head and the central axis 12 of the shaft is reduced from the front view, the torque for turning the club head is reduced.

Wood club (WOOD) is located behind the central axis 12 of the shaft of the center of gravity (14). This has the effect of pulling the clubhead forward, which helps to hit the hitting surface at right angles to the target line 13 at the time of hitting.

Claims (2)

Wood Club (WOOD): The vertical axis 4 of the club other surface 2 seen from the front view makes the angle 7 between the vertical axis 4 and the vertical line 15 degrees or more to face the golfer's eye. WOOD AND IRON CLUB: The shaft shaft 6 is located near the center 3 of the other side of the club so that its vertical distance RF is smaller than the vertical distance RH to the inner point HEEL 9 of the club head.
