Description

[Detailed Description of the Invention] In golf, when hitting a ball with a putter,
Regardless of the shape of the putter head, hitting the ball at the sweet spot in the center of the putter head produces the most force. However, conventional putters have a sweet spot located off the centerline of the shaft.

On the other hand, there are many different ways to hold the putter as each person has their own way of holding the putter. However, if you face the ball directly, your preferred shape will naturally be determined. The way of holding the putter can be roughly divided into: (a) Those who hold the putter head forward.

(b) A person who holds the putter head in a relatively intermediate position.

(c) A person who holds the putter head as if it is hanging firmly in front of him.

It can be divided into three forms.

Therefore, since it is difficult for the ball to hit the sweet spot of the putter head, it is difficult to determine the direction of the ball and the direction in which the ball travels, and the speed of the ball is weakened, making it difficult to determine the force with which you hit the ball, resulting in a poor sense of distance. In addition to poor performance, it also had drawbacks such as unstable batted balls.

Therefore, in order to eliminate the above-mentioned defects, the present invention concentrates the center lines in three directions: the center line of the shaft, the lateral center line of the putter face, and the center line of the putter head in the ball hitting direction, and makes it a sweet spot. This invention relates to a center-concentration type putter for golf, which is characterized by being able to easily adjust the direction of the ball to be hit regardless of how one is holding the stance, to hit the ball with strong straightness, and to increase the hitting power.

The structure of one embodiment of the present invention shown in the drawings will be described. Reference numeral 1 indicates a shaft of a golf putter, and reference numeral 2 indicates a grip portion thereof.

a indicates the putter head, 3 indicates the putter head a
On the main body of the
The opposite side is called the rear. ) has an L-shaped cross section with a thin protruding edge 4, and its main body 3 has a concave arc shape when viewed from the front, with approximately one half of the vertical piece having a thick wall and almost the other half having a thin wall. The sweet spot p of the putter face 5 is biased to one side of the middle part, and the aiming guide 6 of an appropriate length is inserted through the sweet spot p in a direction perpendicular to the putter face 5. The tops of the vertical and horizontal pieces are provided to protrude rearward, and the portion of the protruding edge 4 forming the horizontal piece where the aiming guide 6 is located is formed to protrude rearward in a triangular shape whose width decreases toward the rear. The bottom surface of the body 3 is formed in a convex arc shape slightly downward when viewed from the side, and on one side of the vertical piece of the main body 3, the upper part is bent so as to protrude further forward than the putter face 5, and a A putter head a is constructed by integrally installing legs 8 which have a dogleg shape when viewed from above and have a cylindrical body 7 at the upper end.

Therefore, the lower end of the shaft 1 is connected to the putter head a.
The centerline A of the shaft 1, the centerline B of the putter face 5 in the lateral direction, and the centerline C of the putter head A in the ball hitting direction pass through the sweet spot p.

Next, its effect will be explained. When you hold the putter at address, the head a will naturally move from the state shown by the solid line in Figure 2 to the state shown by the chain line, and the main body 3 will be tilted upward on the other side and downward on the first side, and the center of gravity will be at the sweet spot. Move towards p.

Therefore, if you point the aiming guide 6 toward the hole and hit the ball in the direction of the hole at the sweet spot p, the aiming guide 6 will adjust even the slightest deviation in the direction of the ball, and the ball will move toward the hole. The ball is hit straight toward the ball, and moreover, with the head a, the ball is hit as hard as a hammer, and the probability of the ball rolling in the desired direction at a speed commensurate with the strength of the hit increases the probability of the ball hitting the hole.

The present invention provides a center-concentrated putter for golf configured as described above, in which the center lines of the shaft in three directions, the center line of the putter face in the lateral direction, and the center line of the putter head in the ball hitting direction are concentrated at one point. Since this is the sweet spot, if you hit the ball at that sweet spot, the ball will be hit hard, just like hitting it with a hammer, and the ball will go straight, so you don't have to use any force in your hands to hit it. , the ball travels straight toward the target at a speed commensurate with the required force of the strike.

Furthermore, if you stand this putter on the ground and spin it, it will spin like a top, and if you support and hold the balance point of the shaft with your fingers, the center line of the putter head in the direction of ball hitting will be vertical, and the putter face will be horizontal. Not only is the putter stable, but when you hold the putter up, the center of gravity naturally moves toward the sweet spot. Therefore, even though each person has a wide variety of ways to hold the putter, it is possible to adapt to all the ways of holding the putter to further increase the hitting power, and to easily match the direction of the ball to help the ball enter the hole. A good cut-in can be achieved.

In addition, since the upper part of the leg on which the shaft is attached to the putter head body is bent so as to protrude further forward than the putter face, the center line of the shaft can be accurately aligned with the putter face and the shaft can be installed.
Moreover, the center line of the shaft can be directed to the sweet spot.Furthermore, a triangular ridge is provided at the rear of the lower edge of the putter head body, and the bottom surface of the body with the ridge is convex downward when viewed from the side. Because it is arc-shaped, it is easy to stand the putter on the ground, and
When hitting a ball, the flange has the effect of applying a batting force, and the flange does not adversely affect the ball-striking action.

Moreover, it has an extremely simple structure and can be manufactured easily and inexpensively.
