DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf putter head having a momentum of inertia focusing / weight balance adjusting member disposed behind and behind a sweet spot of a head face of a golf putter.

[0002]

2. Description of the Related Art Heretofore, there have been many proposals for the shape of a golf putter head. FIG. 10 shows an example of such an L-stick type having the same shape as a general iron club.
There is a type in which a strip-shaped sole is attached to the back of the L-stick type face.

[0003]

According to the present invention, the trajectory of the swing of the putter head can be clearly seen, the trajectory can be confirmed in the practice swing before the actual performance, and the inertia of the whole including the head and the inertia concentrated on the striking surface can be improved. The purpose of the present invention is to provide a good swing balance and good hit ball balance and to adjust the weight balance of the head to a balance suitable for the user's feeling.

[0004]

SUMMARY OF THE INVENTION A momentum of inertia is concentrated on a sweet spot of a head face of a golf putter, and a momentum inertia focusing / weight balance adjusting member for adjusting the balance of the golf putter head and the overall weight is provided behind the putter head face. A golf putter head is provided rearward.

[0005] The inertia moment focusing and weight balance adjusting member may be configured to be detachable by a mounting means such as a bolt.

[0006] The moment of inertia focusing / weight balance adjusting member may be configured such that the weight of a front portion, an intermediate portion or a rear portion thereof is adjustable.

The inertia moment focusing / weight balance adjusting member includes a fine adjustment balancer having a trapezoidal groove on the bottom surface.
It is also possible to adopt a configuration in which it is fitted and mounted on an engagement ridge provided on the upper surface of the front, intermediate or rear portion of the inertia moment focusing / balance adjusting member.

A concave receiving seat is formed at a front portion, a middle portion or a rear portion of the moment of inertia focusing / weight balance adjusting member;
The whole or a part of the bottom of the fine adjustment balancer adapted to the recessed seat may be fitted, and the fine adjustment balancer may be integrally or interchangeably attached by a pressure-sensitive adhesive or other fixing means such as an adhesive or a screw. Things.

The inertial moment focusing / weight balance adjusting member may be provided with a frictional resistance reducing member on the bottom surface.

[0010]

Since the golf putter head of the present invention is constructed as described above, the swing trajectory of the required long inertia moment focusing / weight balance adjusting member can be clearly seen in the left and right directions.
The swing direction can be sufficiently confirmed on this track, and an accurate swing can be performed. Further, the golf putter head has a good balance, and the momentum can be focused on the hitting surface, the kinetic energy can be transmitted to the ball without swinging the hitting surface, and the ball can be hit in the target direction.
