[0012]

Many golf club putters have been described in which the face of a conventional golf club putter head has a low center of gravity and the sole surface has a sufficient weight distribution in two directions of the toe & heel side.

Regarding the center of gravity of the face of the golf club putter head, most of the center of gravity of the face is low, but there is also a golf club putter simply having a structure of high center of gravity of the face.

Since such a putter head attaches importance to the sitting of the sole when addressed, it is likely to be the center of gravity in the front.

[0015] Therefore, it is unsatisfactory to find a putter club having a three-dimensional center of gravity shift that can correct the golfer's individual habit to correct ball rotation.

However, in the case of a three-dimensional center-of-gravity moving putter club such as the present invention, the rear center of gravity of the sole, the level sole, and the bounce sole have poor seating at the time of addressing, so they are treated as defective products. Is the current situation.

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

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

As a result, there are many types of players who give up, saying that no matter how many books they buy, they are the same. However, it is the current situation that the changes are mainly due to changes in materials, face design, and delicate workman's sharpeners.

Anyway, the golf club putter makes it possible to gently acquire an important sense of distance, which not only makes golf play easier but also makes it more enjoyable. in short,
The challenge is to put 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 a backswing with a putter, many advanced players and intermediate players have a tendency to run the heel part first, so it is necessary to correct it.

At any rate, the theoretical data on the sole design and the interlocking with the sole rear center of gravity in the high center of gravity face is an undeveloped field at present.

[0026]

SUMMARY OF THE INVENTION According to the present invention, a golf club putter head face surface has a high center of gravity so that the weight is concentrated from the heel side to the vicinity of the center so that the weight of the golf putter head sole weight is adjusted by adjusting the center of gravity ratio and the sole shape. ,
The sole heel heel center of gravity structure has been developed mainly to give a smooth backswing and ball rotation to give front rotation that tends to cause topspin, and to prevent face shake 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, 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 helps adjust 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 of the upper part of the face excluding the sole part of the golf club putter head in the top line direction, and from the heel side to the center to concentrate the mass and create a high center of gravity, there is a tendency to start the swing from the heel part. Helps golfers to swing smoothly.

Further, regarding the center of gravity of the sole, even if it is the center of gravity of the conventional scoop sole, a weight is attached to the rear part of the sole to make the center of gravity of the rear part or bounce sole.

As a result, the golf club shaft and the golf club putter head are likely to be parallel to each other on the backswing, and the ball can be smoothly squared at the time of impact, the down blow that makes it easy for the hand after the impact to move forward, and the effect of smooth flow acceleration. Not only can you wrap it up, 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 from 100 years ago to the present 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 sole putter with a large bounce angle so that the center of gravity of the sole will be behind the face side and the side opposite to that of an advanced player. Not only will it be the same as hitting a putter with a little floating, but the angle of incidence will be more likely to be down blown.

The high center of gravity in which a weight is placed on the upper face and the rear center of gravity structure on the rear side of the sole improve the theory obtained by Seiichiro Teramoto, a US patent, for a golf club set for a putter. US Patent No. US 6.315.678. B1.

When performing a backswing with a golf club putter, for an advanced player who starts the swing from the heel first, the heel portion of the rear part of the sole is set particularly heavy so that it is lightly attached to the center, or the heel portion is set to be lighter at the beginning. It is also possible to hang it from the side to the center and put the weight on average.

As a concrete explanation, a player who starts a swing from the heel can set the vicinity of the heel to be heavier, and in the case of the backswing, the brake can be applied to the heel portion to prevent the heel portion from opening, so that the backswing can be performed easily. it can.

Furthermore, the synergistic effect of the vertical and horizontal center-of-gravity ratio 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 so that it extends from the rear heel side to the vicinity of the center, the moment of inertia can be increased and the sweet area can be expanded.

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 if 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 of the sole of the putter head, the mistake phenomenon of a sense of distance that tends to occur during long putters and tensions, which is often experienced by general amateur golfers Can be tempered.

Also, regarding the weight adjustment of the upper face,
Changing from the center to the toe side so that it gradually becomes lighter, and even in the state of the bounce sole or flat sole mentioned above, it becomes a preferable state and it is a state where pre-rotation of the ball that is top spin is easy to come out Can be easily created.

Next, regarding the adjustment 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 ratio of the center of gravity of the front surface, which is the front part of the sole, which is the direction in which the ball hits the ball, to 51%, and the center of gravity of the rear surface, which is the rear part of the sole on the opposite side, to 51%, the reaction effect and impact moment of inertia are improved.

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

As an example, when the front surface of the sole of a 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 of the front and back of the golf club putter head face from the high center of gravity heel side to the vicinity of the center. For the adjustment of the heavy mass portion, a material having a high specific gravity such as tungsten is used. 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, a material such as aluminum or magnesium having a low specific gravity is embedded from the center of the high center of gravity of the face toward the toe direction. Just emphasize it.

By doing so, the upper and rear center of gravity of the putter face can be finely and freely set, and the optimum center of gravity position can be set.

[0048]

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.

The neck near the mounting portion of the shaft is important for adjusting the position of the center of gravity. However, the neck itself has a golfer's preference, and the neck 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 behind the extension line of the shaft. Therefore, the gooseneck may be used if desired. The moment of inertia and center of gravity of the putter head are important themes, 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 golf club putter heads in Figs. 6, 7, 8 and 9, the center of gravity of the sole part of the golf putter head is more forward when the face surface is in front of the extension line of the mounting neck portion of the shaft. It is preferable because it tends to become the rear part and the ball is accelerated and stretches easily.

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

Particularly, for the skeleton of the face surface and the basic portion having a large area, and the skeleton of the sole surface and the basic portion having a large area, a material having a low specific gravity or a thin material is used so that the face high center of gravity and the sole rear center of gravity can be adjusted. Such a structure is desirable if possible because it can be emphasized and the moment of inertia and the reaction effect are likely to occur.

Further, it is desirable that the back weight weight (β) at the rear portion of the sole be 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.

Also, the bounce angle needs to be made larger for beginners. 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, there are many players who imagine the past experience and sitting state, and in some cases it becomes slightly hard 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.

Further, regarding the specifications of the front and back of the upper part of the golf club putter face, it is desirable to set the balance weights at the high center of gravity on the heel side and near the center to usually increase from 10 g to 50 g for conventional products.

In this case, not only the weight of the balance member extending from the heel side to the vicinity of the center is simply increased, but also the weight is gradually reduced by extending from the heel to the toe side to use a material having a high specific gravity. From the side to the vicinity of the toe, a part of the material with a low specific gravity is used, such as magnesium or aluminum, brass, or ceramics and other various specific gravity materials may be inserted or used as a hybrid.

Further, by using a material such as 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 toe below to the heel,
The high center of gravity can be emphasized.

Here, the bent practice green distance 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 the conventional golf club putter and the product of the present invention were compared, it was found that the bending from the front side of the pin was reduced by 40% or more. 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 comparison of 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.
