Benefits of technology

The golf club described in this patent makes it easy to determine if a ball hit the sweet spot based on the sound it makes when hit.

Problems solved by technology

Therefore, it is difficult to judge whether the ball was hit in the sweet spot, based on the hitting sound.
However, it is also difficult to amplify the hitting sound of the golf putter sufficiently even with the structure disclosed in Japanese Unexamined Patent Application, Publication No.
H9-70460, and thus it is still difficult to judge whether the ball hit the sweet spot, based on the hitting sound.

first embodiment

[0019]A golf club according to a first embodiment of the present invention illustrated in FIGS. 1 and 2 is a putter. The golf club includes a shaft 1 and a club head 2 provided at an end of the shaft 1.

Shaft

[0020]Publicly known shafts can be used for the shaft 1. A grip (not shown in the figure) held by a player (user) is attached to the end opposite to the club head 2 of the shaft 1.

[0021]Any shaft for a golf club can be used for the shaft 1. In other words, the material, diameter and length of the shaft 1 are not particularly limited.

Club Head

[0022]The club head 2 includes a head body 3 and a plate-like face member 4 provided along a hitting face of the head body 3. The face member 4 is fixed to the head body 3 at parts of the upper edge surface and parts of the lower edge surface, more specifically, only two locations of the upper edge surface and two locations of the lower edge surface.

[0023]The shape and size of the club head 2 are not particularly limited so long as it can be ...

second embodiment

[0052]A golf club according to another embodiment of the present invention illustrated in FIGS. 3 and 4 includes a shaft 1 and a club head 2a provided at an end of the shaft 1.

[0053]The shaft 1 of the golf club shown in FIG. 3 may be similar to the shaft 1 of the golf club shown in FIG. 1.

Club Head

[0054]The club head 2a includes a head body 3a and a plate-like face member 4a provided along a hitting face of the head body 3a. The face member 4a is fixed to the head body 3a only at two locations on an upper edge surface of the face member 4a. In other words, a lower edge surface of the face member 4a is not fixed to the head body 3a.

[0055]The configuration of the head body 3a and the face member 4a of the golf club shown in FIG. 3 may be similar to the configuration of the head body 3 and the face member 4 of the golf club shown in FIG. 1, except for the configuration relating to the fixation of the face member 4a to the head body 3a.

[0056]Two fixation projections 11 are provided at...

Abstract

A golf club includes a shaft, and a club head provided at an end of the shaft, wherein: the club head includes a head body and plate-like face member provided as a hitting face of the head body; and the face member is fixed to the head body only at a part of an upper or lower edge surface, or parts of both upper and lower edge surfaces of the face member. A fixing position of the face member may be located in the proximity of a node of a characteristic vibration in a case of freely supporting the face member. The Rockwell C-scale hardness of the face member is preferably no less than 40. The face member may be fixed to the head body by a set screw, at two locations of the upper edge surface, and two locations of the lower edge surface of the face member.

Description

TECHNICAL FIELD[0001]The present invention relates to a golf club.BACKGROUND ART[0002]When playing golf, it is important to hit a ball in the center of the hitting face of a club head (so-called “sweet spot”). As a basis for a player judging whether the player hit the ball in the sweet spot, hitting sounds are considered. Therefore, commercially available woods, in particular, drivers, etc., are designed while taking into account such hitting sounds.[0003]Among clubs, putters are accompanied by smaller hitting sounds since a ball is hit with a relatively little power. Therefore, it is difficult to judge whether the ball was hit in the sweet spot, based on the hitting sound. In order to address such a situation, Japanese Unexamined Patent Application, Publication No. H9-70460 discloses a golf putter which enables the hitting sound to be relatively amplified by adopting an inverted box-like head opened at the rear surface. However, it is also difficult to amplify the hitting sound of ...
