Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter head used for golf.

[0002]

2. Description of the Related Art Conventionally, golf putters have been devised in various ways for hitting a ball on a sweet spot at the time of putting for the final cup-in of a golf game. While improvements have been made regarding the shaft, many improvements have been made regarding the putter head provided at the tip. For example, JP-A-10-137374, JP-A-2001-25518,
A balancer is provided on the putter head as in JP-A-2001-137400.

[0003]

The conventional techniques described above include the case of providing a weight member having a large specific gravity by partially changing the material of the golf club head, as in Japanese Patent Laid-Open No. 2002-65913. Kaihei 10-137374, Japanese Patent Laid-Open No. 2001-137400, such as screwing a weight member to an arbitrary position, has problems in easiness of manufacture, appearance, etc. It is difficult to distribute the depth of center of gravity and the load balance between the toe and heel.

Therefore, the inventor of the present invention is easy to manufacture, has a good appearance, and has a feature that the position of the center of gravity and the depth of the center of gravity are sufficient, and that the load balance between the toe part and the heel part can be distributed. I examined the head.

[0005]

As a result of studying the above-mentioned problems, as a result of a reserve portion provided at the rear of the face portion, a weight support wall provided upright from the reserve portion, and a weight portion above the weight support wall. The putter head is characterized in that the weight portion is provided above and behind the face portion so as to deepen the depth of the center of gravity, and the sweet spot is enlarged in the center portion of the face. The weight portion, which is higher than the face portion, may be changed in material, shape, specific gravity, and the like as necessary in terms of hitting performance and appearance.

Further, a hole is formed in the weight supporting wall which is provided upright from the reserve portion, and the wall surface formed on both sides of the hole applies a weight load to the toe portion and the heel portion.

The holes formed in the weight support wall can change the load applied to the toe portion and the heel portion depending on the size and the position where the holes are provided, to distribute the balance between the left and right face portions.

1 is a front view of a putter head according to the present invention, FIG. 2 is a right side view, FIG. 3 is a plan view, and FIG. 4 is a rear view. This putter head is provided on the shaft 1 and has a face portion 2 on the front surface as in the conventional case. The back portion of the face portion 2 is characteristic, and a retaining portion 3 is provided in the lower rear portion of the face portion 2. A weight supporting wall 4 is provided upright from the retaining portion 3, and a weight portion 5 is provided above the weight supporting wall 4. Therefore, the weight portion 5 exists behind the upper portion of the face portion 2, and the load is transmitted to the face portion 2 via the weight support wall 4 (with the weight concentrated on the upper rear portion of the putter face) and the retaining portion 3. The depth of the center of gravity is deepened and the sweet spot P is enlarged in the center of the face 2.

A weight support wall 4 standing upright from the retaining portion 3.
A hole 6 is provided in the hole. Depending on the shape and position of the hole 6 provided in the weight support wall 4, the load applied to the toe portion 7 and the heel portion 8 can be changed by the wall surfaces formed on both sides of the hole, and the right and left sides of the face portion 2 can be changed. You can distribute the balance to.

FIG. 5 shows how the putter head is used. By concentrating the weights on the upper back of the face portion 2, the golf ball 9 hits the sweet spot P at a high position in the center of the face portion 2 during putting,
By giving more energy to the hitting point of the ball than for the upper part for a long time, the ball makes a forward rotation motion. As a result, putting with good linearity and good rolling can be performed.

FIG. 6 is a left side view of a putter head according to another embodiment of the present invention, and FIG. 7 is a plan view. This putter head also has the weight portion 5 concentrated in the upper rear portion of the face portion 2. However, the weight support wall 4 and the retaining portion 3 are formed to be narrower than those in the above-described embodiment. Also in this example, when the golf ball is putted, the sweet spot P at a high position in the center of the face portion 2 hits, and more energy is given to the hitting point of the ball for a longer time than at the upper portion, so that the ball is rotated forward.

[0012]

Since the putter head of the present invention has a wide sweet spot, it is easy for the ball to hit the sweet spot during putting for the final cup-in of a golf game. By giving a lot of energy for a long time after hitting the ball, a forward rotation motion occurs in the ball. As a result, putting with good linearity and good rolling can be performed.

The position of the center of gravity and the depth of the center of gravity are sufficient, and the load balance between the toe part and the heel part can be distributed, which is convenient and improves the probability of cup-in.
