AI Technical Summary

Benefits of technology

The present invention is a wood club head that can be adapted to different hosel lengths. By considering the hosel length, face progression, and barycenter depth, the club head can create a strong trajectory and long traveling distance when hit by a golfer with high head speed. The club head can draw a sweep trajectory or a down blow trajectory depending on the hosel length, which affects the ball's rise and spin. By adjusting the loft angle, the club head can achieve a strong trajectory and long traveling distance with a ball that does not rise too high or too low.

Problems solved by technology

The larger the FP value, the more easily the ball tends to rise high, but the worse ball grippability becomes.
Such a ball tends to yield to the wind and lose its traveling distance.

Embodiment Construction

[0015]A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[0016]FIGS. 1 and 2 are a side view and front view, respectively, of a wood club head having a loft angle of 13° or less. A head main body 1 is provided with a hosel 2. A shaft (not shown) is fixed into the hosel 2. The distance from a face 3 of the head main body 1 to the barycenter is defined as a barycenter depth ZG. A length HL of the hosel 2 represents the length of the cylindrical portion. The distance from a shaft axis S to a leading edge 4 is defined as a face progression (FP).

[0017]As the head main body 1, the embodiment used one which was made by casting stainless steel and had a volume falling within a range of 150 cm3 to 250 cm3 and a head weight falling within a range of 200 g to 250 g. When the vertical distance from a sole 5 of the head main body 1 to a barycenter position CG was defined as a barycenter height, the barycenter height was designed to 18 mm...

Abstract

A wood club head having a loft angle of not less than 13° is provided. The hosel length is not less than 20 mm. The face progression is set to fall within a range of 12 mm to 16 mm (both exclusive). The barycenter depth is set to fall within a range of 20 mm to 25 mm (both exclusive).

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a wood club head having a loft angle of 13° or more, or a head of so-called fairway wood.[0003]2. Description of the Related Art[0004]In a conventional fairway wood, the amount of spin, the ball grippability, and the like are designed by variously changing the values of a barycenter depth (ZG) representing the distance from the face to the barycenter, a face progression (FP) representing the distance from the shaft axis to the leading edge of the face, and a hosel length representing the length of the cylindrical portion of the hosel. When the value ZG is large, the face tends to be directed more upward upon impact, and the ball can spin and rise higher more easily. The larger the FP value, the more easily the ball tends to rise high, but the worse ball grippability becomes. A loft angle is the measurement value of an angle formed by the shaft and face when the face is set in a square st...
