[0012]

The face of a conventional golf club putter head has a low center of gravity, and many golf club putters have a sole surface that sufficiently distributes weight in two directions, a toe side and a heel side. .

As for the center of gravity of the face of the golf club putter head, the center of gravity of the face is mostly low, but some golf club putters simply have a structure of high center of gravity.

In such a golf club putter, since the sitting of the sole when addressing is emphasized, the center of gravity of the front is likely to occur.

Therefore, a golf club putter having a three-dimensional structure design that can correct the sitting of the sole, the front center of gravity, and the habit of the individual golfer to correct the rotation of the ball, unlike the present invention, cannot be found.

In the case of a three-dimensional center-of-gravity moving putter club such as the product of the present invention, the rear center of gravity of the sole, the level sole, and the bounce sole are poorly seated at the time of addressing, and are treated as defective products. Is.

In any case, the front center-of-gravity structure with the same scoop sole as in the prior art causes too much backspin and unstable slippage, and it is difficult to adjust the distance.

A conventional putter club design theory is a two-dimensional structural design in which the face has a low center of gravity and the front center of gravity of the sole, and this theory has continued for almost 100 years.

As a result, it is a fact that many players are in a state of giving up, saying that no matter how many books they buy, they are the same. However, the main changes are the evolution of materials and the emphasis on face design.

At any rate, by proposing a golf club putter capable of easily obtaining a sense of distance, not only golf play becomes easy but also fun. In short, the challenge is a golf club putter that can easily hit the hole.

Therefore, if the structure is such that the square before impact, the square at impact, and the down blow after impact are likely to be formed, the three-dimensional structure design of the center of gravity that makes it easy to wrap the golf ball with the top spin is made, and slip is improved. It is easy to get a feeling.

However, when addressing golf club putters, it is generally said that the combination of the low center of gravity of the face and the scoop sole is the best putter club that is comfortable to sit for professional golfers and amateur golfers.

As a result, the directionality is improved due to the backspin and the toe and heel effect in the stroke of the golf club putter, but there is an important problem that the distance is insufficient before the pin.

Further, in the case of backswing with a golf club putter, many advanced players and intermediate players have a tendency to run the heel portion first, so it is necessary to correct it.

At present, theoretical data on the sole design and the linkage between the position of the center of gravity and the moment of inertia in a high center of gravity face is an undeveloped field.

[0026]

SUMMARY OF THE INVENTION According to the present invention, the golf club putter head has a high center of gravity and is concentrated from the heel side to the center to concentrate the mass, and the weight of the sole weight of the golf putter head is focused on the center of gravity ratio and the sole shape. By adjusting the moment of inertia of the deep center of gravity, a smooth backswing and rotation of the ball are given to give a front rotation that easily causes topspin, and to prevent the movement of the face at impact.

In particular, the scoop sole, the flat sole, which is the sole design of the golf club putter head,
The synergistic effect of each shape of the bounce sole and its center of gravity ratio and the high center of gravity that concentrates the mass from the heel side to the center of the face is useful for adjusting the stroke and top spin depending on the player's level.

Anyway, a golf club putter head having a low center of gravity of the face and a front center of gravity of the sole surface is prone to backspin and requires a considerable amount of practice in order to practice a sense of distance, so some kind of ingenuity is required.

As a method of quickly obtaining a sense of distance, first,
By moving the center of gravity in the top line direction of the top part of the golf club putter head excluding the sole part and concentrating the mass from the heel side to the center to make it a high center of gravity, for golfers who have a tendency to start swinging from the heel part On the other hand, it helps a smooth swing.

Further, regarding the center of gravity of the sole, even if it is the center of gravity of the front of the conventional scoop sole, by attaching a weight to the rear part of the sole to some extent to make it a moment of inertia of the rear center of gravity or to make a bounce sole. Good.

As a result, the golf club putter shaft and the golf club putter head are likely to be parallel to each other on the backswing, and the square effect before the impact starts, the square at the time of impact, and the down blow where the hand after impact is likely to go forward. Not only can you wrap the ball with the effect of smooth flow acceleration, but you can also accelerate the front rotation.

This theory is an epoch-making golf club putter head in which the basic design structure of a golf club putter club from 100 years ago to the present time is fundamentally changed as a center of gravity movement theory.

Not only beginners and intermediate players but also golfers who are not good at putting can use a putter with a large bounce angle so that the center of gravity of the sole becomes the rear part on the side opposite to the face side and putter swing for advanced players. Not only does it become the same as hitting the putter with the same putter slightly floated, but the ball runs well and the incident angle tends to be a down blow.

The high center of gravity with a weight placed on the upper face and the rear center of gravity structure on the rear side of the sole were acquired by Seiichiro Teramoto for a US patent for the golf club set. US Patent No.US 6.3
15.678. B1.

The basic design of the golf club putter of the present invention is an improvement of the structure of the driver head of the golf club for the putter of the golf club.

When making a backswing with a golf club putter, for a player who starts a swing from the heel first, the heel side may be set particularly heavy so that it is lightly attached to the toe part.

As a concrete explanation, a player who starts a swing from the heel can set a heavy weight in the vicinity of the heel to brake the heel portion and prevent the heel portion from being overly covered in the case of a backswing, and the face is straight. It is easy to become.

Further, the synergistic effect of the vertical and horizontal center of gravity ratios of the sole and the increase of the moment of inertia allows the golf club putter head to be adjusted according to the golfer's individual habit, so that not only the backswing becomes smooth, but also the top swing. The spin is easier and the ball runs better.

Next, by slightly bouncing the sole of the golf club putter head, the moment of inertia in the rear direction can be strengthened, which not only positively affects the expansion of the sweet area but also improves the directionality.

As a method of adjusting the center of gravity from the leading edge (front part of the sole) of the golf club putter head to the backsole, moving the center of gravity in the direction of the backsole (rear part of the sole) of the putter head causes a slight duplication phenomenon. Even when the ball comes out, the face surface against which the ball hits is likely to face upward, and it is easy to hit the rear part of the sole, and the double phenomenon on the green can be softened.

As described above, by adjusting both the sole design of the golf club putter head and the center of gravity and moment of inertia of the sole of the putter head, it is possible to obtain a sense of distance that tends to occur during long putters and tensions, which are often experienced by general amateur golfers. The error phenomenon can be softened.

It is also preferable to adjust the weight of the upper part of the face, but to change the weight from the center to the toe side so that the weight is gradually reduced, and in the state of the bounce sole or flat sole described above. Then, it is possible to easily create a state in which the front spin of the ball, which is the top spin, is likely to occur.

Next, regarding the adjusting weight in the ratio of the center of gravity of the sole in the cross section of the golf club putter head, basically, when the sole portion is excluded except the face portion,
By setting the front center of gravity, which is the front part of the sole, which is the direction in which the ball hits, to be 49%, the rear center of gravity, which is the rear part of the sole on the opposite side, has a ratio of 51%, which increases the moment of inertia for impact and increases the sweet area. It contributes to increase the directionality.

In this golf club putter head center of gravity ratio 36 type design, it is preferable to use at least three types of materials having different specific gravities, but even in the adjustment of a single material, one model is produced. It is possible.

As an example, when the front surface of the sole of the golf club putter head is lightened, a resin-based material, titanium-based material, aluminum, or a material having a low specific gravity such as magnesium is used alone or in a hybrid structure. When the rear surface is made heavy, a single material or a hybrid structure is preferably used as the adjusting weight material, which is a heavy material such as brass, tungsten, steel, or a heavy ceramic such as a heavy ceramic.

Further, the adjustment is made by concentrating the mass from the high center of gravity heel side of the front and back of the golf club putter head face to the center, but for the adjustment of the heavy part, a material having a high specific gravity such as tungsten is used. It may be embedded as a solid weight.

Further, as a method of emphasizing a portion where the mass is concentrated from the heel side of the high center of gravity of the face to the vicinity of the center, materials such as aluminum and magnesium having a low specific gravity are embedded from the vicinity of the center of the high center of gravity of the face toward the toe direction. You can emphasize it with.

By doing so, the weight distribution of the upper part of the putter face and the moment of inertia can be finely and freely set, and a smooth swing is possible.

[0049]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. The center of gravity weight adjustment and the sole shape of the golf club putter head used in the present invention may be integrally molded as a golf club design at the time of manufacturing, or may be attached to a completed club later.

Further, it is important to adjust the position of the center of gravity of the neck near the mounting portion of the shaft. The neck itself has a golfer's preference, and it may be straight or bent.

However, as the neck of the putter club head, there are many gooseneck shapes in which the face surface is on the rear side of the extension line of the shaft, so the gooseneck may be used as desired. The adjustment of the moment of inertia and center of gravity of the putter head is an important theme, and the shape of the neck can be adjusted to your liking.

If possible, FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG.
・ As shown in the sectional views of the putter club heads in Fig. 6, Fig. 7, Fig. 8, and Fig. 9, the center of gravity of the sole part of the golf putter head is rearward when the face surface is in front of the extension line of the mounting neck of the shaft. It is preferable that the ball tends to be accelerated and the ball is easily accelerated and easily stretched.

Usually, a beginner or an intermediate player often hits the lower part of the golf ball strongly, and as a result, a low back center of gravity results in a large backspin, which makes it difficult to adjust the sense of distance to the pin. In many cases, a high center of gravity face is desirable to avoid it.

Particularly, for the skeleton of the face surface and the basic structure having a large area and the skeleton of the sole surface and a basic portion having a large area, by using a material having a low specific gravity or a thin material, the high center of gravity of the face and the rear center of gravity of the sole are used. Can be emphasized,
Such a structure is desirable if possible because it is easy to obtain the moment of inertia and the hammer effect that the sweet area becomes wider.

Further, the back weight weight (β) at the rear part of the sole is preferably set in the range of 10 g to 50 g in the conventional product. However, when a part of the golf club putter head has a hollow structure, the maximum weight is 100 g.

Next, in order to easily obtain the top spin, the bounce sole is most suitable for the sole shape of the golf club putter head. Of course, if the weight (β) of the back weight is attached to the bounce sole, not only the moment of inertia of the rear part is further emphasized, but also a lot of double phenomenon on the green is softened.

Further, the bounce angle needs to be made larger for a beginner. It is desirable for beginners to be about 5 degrees, but for intermediate people it is desirable to be around 2 to 3 degrees because of the image of sitting at the address.

For intermediate and advanced players, it is well understood that the swing pattern for taking a lot of backspin, which is similar to that of a beginner, is reduced, and the top spin, which is the front rotation of the ball, is preferable.

With a bounce sole, many players imagine the past experience and sitting state, and in some cases, it becomes slightly difficult to hit. A flat sole is optimal for the sole shape of the putter head.

For the advanced player, many players practice top-spin pre-rotation batting, and many players are conservative in their image. Therefore, in the case of the bounce sole or flat sole of the putter head, the ball is placed at a high position. Since the hit becomes too high, the shape of the putter head sole is the scoop sole, and the rear center of gravity of the sole is optimal.

As for the scoop sole of the golf club putter head, even an advanced player should not be extremely large. Therefore, normally 2 to 3 degrees is optimal, and 5 degrees or more is not preferable.

Regarding the specifications of the front and the back of the upper part of the putter face, it is desirable to set the balance weight from the heel side to the center in the high center of gravity to an increase of 10 g to 50 g in the conventional product.

In this case, not only the weight of the balance material from the heel side to the center is simply increased, but also the weight is gradually reduced by extending from the heel to the toe side, and a material having a low specific gravity is used, or from the center to the toe. On the other hand, in some cases, various types of specific gravity materials such as magnesium, aluminum, brass, and ceramic, which have a low specific gravity, may be inserted or used as a hybrid.

Further, by using a magnesium or a resin having a low specific gravity from a portion using tungsten or the like on the upper face to a portion extending from the lower toe to the heel,
The high center of gravity can be emphasized.

Here, the distance of the bent practice green is 15
Assembled a golf club putter head of the present invention using a normal putter shaft and grip at an inclination of ± 0.5 degrees, and a total of 100 men and women from professional to handicap ages 30 to 75 years old As a result of human test, it was popular that 70% to 80% or more of golfers hit the ball well.

Further, when comparing the conventional golf club putter with the product of the present invention, it was found that the bending from the front side of the pin was reduced by about 30% to 40%. In addition, the sound when entering the hole cup feels more than conventional putters. As a result, the small amount of bending contributes not only to the accuracy of the direction but also to the accuracy of the distance, which is the main purpose of the development.

Table 1 shows the contents of comparison between the conventional golf club putter and the golf club putter of the present invention used in the human test.

[Table 1] Comparison table of specifications of the present invention product and conventional golf club putter

The reason why I was involved in the human test this time is that the current robot test is a robot, and only fixed data can be obtained. Golf is played by humans, not robots. Anyway, there is only a human test to collect the data of human's delicate touch such as pressure and habit on the green.
