GOLF CLUB HEAD

WIPO Patent Application WO/2012/124963

A2

The present invention relates to a golf club head. The golf club includes an iron, a wood, a wedge, a utility iron, a hybrid iron, a fairway wood and a hybrid. The golf club head includes: a head body (B) consisting of a face (F), a sole (S), and a back (BK) forming a back surface; a hosel (H) and a neck (N) for connecting the head body (B) to a shaft; and section modulus adjusting means for decreasing the cross-sectional surfaces of the hosel (H) and of the neck (N). The golf club head according to the present invention is configured such that the section modulus decreases during the process of transferring the impact applied to the head body (B) to the hosel (H), so as to microscopically improve the function of the golf club head as an elastic body, thus enabling the golf club head to absorb impacts as if a microscopic spring were interconnected between the head body (B) and the hosel (H), and thus absorbing and dispersing the impact being transferred to the hand of a golfer with the result that golfer's elbow is prevented, and damage to the shoulder joint, damage to the wrist joint, and damage to muscles may be reduced. Since the total weight of the neck (N) or of the hosel (H) decreases, the weight of the head body (B) should be increased so as to meet the prescribed total weight, and accordingly the increased weight of the head body (B) increases driving distance.
