Description

Detailed Description of the Invention: (1) "Concept of the present invention," (2) "Problems and drawbacks of conventional methods," (3) "Characteristics and contents," and (4) "Effects and disadvantages of the present invention." The overall process leading up to ``impact'' is explained item-by-item as follows.

(1) Concept of the present invention: The present invention employs an independent suspension club face system supported by a power spring mechanism, which is completely different from the conventional concept, for the club head. This is an innovative golf golf course that aims to increase the ball flight distance of so-called fairway woods from (1 wood) to creek (5 wood) by about 10% to 30%.
This concerns the development and commercialization of clubs.

By adjusting the strength of the springs that make up the power spring mechanism, this club allows you to adjust the instantaneous force of the club face and increase or decrease flight distance. It is also possible to adjust the flight direction.

Furthermore, this concept can also be applied to putters by changing the response to environmental conditions.

At the end of this section, a brief overview of "golf" will be described below as a reference for the present invention.

There are various theories about the etymology of golf and its origin, but the place where modern golf was developed was Scotland, England, where the first Royal Golf Club was opened in 1834, and half a century later, A golf club was formed in the United States in 1887.

In Japan, a British resident of Kobe built a small four-hole course on Mt. Rokko in 1901.
With the establishment of the Tokyo Golf Club in 1914 (Taisho 3) by Japanese, the golf world in Japan rapidly developed, and the first Japan Open Championship was held in 1927 (Showa 2), and the
In 931), the first Japan Professional Championship was held, etc.
It reached its first heyday in the so-called ``pre-war'' early Showa period.

After a hiatus during the war, Japan restarted as a peaceful nation after the war, and along with economic recovery, golf became widely popular as a national sport, and thousands of large and small golf courses were opened across the country. Currently, Japan is approaching the top level of technology in the world.

In this process of development of domestic and international golf, with the passage of time, it sometimes depends on the improvement of tools such as clubs and balls.
Additionally, in some cases, the emergence of revolutionary new balls with longer flight distances has changed the concept of courses up until then, leading to the modernization of courses, and these two factors have combined to promote the development of golf. It can be said that

Especially recently, with the development of various materials, it is often seen that these materials are being used for purposes other than their original purpose, such as the appearance of black shafts in place of conventional steel shafts,
A very recent example is the rise of metal heads as an alternative to traditional wood heads.

However, the present invention represents the emergence of a golf club that is even more innovative than these, and depending on how things progress in the future, it has the potential to completely change the course concept of golfers around the world.

By acquiring domestic and foreign industrial property rights based on the present invention, we aim to contribute to the development of industries related to our country, and also to the acquisition of foreign currency, which is expected to deteriorate the environment in the future.

(2) Problems or disadvantages of the conventional method: The following are the problems or disadvantages of the conventional method that are relatively noticeable depending on the embodiment of the present invention. It is as follows.

Conventionally, the only energy available to fly the ball was the kinetic energy given to the ball from the club head through impact, and the internal stress that tries to restore the deformation strain that the ball itself receives at the moment of impact. It was not possible to utilize the trampoline effect caused by the repulsive force of the strong spring built into the club head itself.

In other words, if we consider the moment of impact, the force applied to the ball at that moment is stronger than expected, and the speed of the head is 40 m/s.
The ball is hit at ~50m, but at that moment the ball collapses and deforms to the limit due to the inertia effect due to its own weight, and during that time it contacts the club face for 1/2,500 seconds to 1/2,000 seconds, and then The synergistic effect of the internal energy of recovery and the energy of movement from the head creates a repulsive force that instantly and forcefully launches the ball.

On the other hand, the harder the ball, the greater the repulsion force and the longer the flight distance, but this is more noticeable for hard hitters whose head speed is over 45 m/s, and the effect is weakened when the head speed is less than 40 m/s, so the ball will travel farther. It was more effective to stabilize the direction with a soft ball that released slowly.

Also, it makes sense that only the driver and putter are sold separately among golf clubs; each has a strong individuality, and if the club doesn't match the personality of the player who uses it, This is because the functions cannot be fully demonstrated.

Originally, the purpose of a driver was to increase flight distance, and a putter was used to get into holes, and the purposes were different in that they were responsible for the start and finish of each hole, respectively, but other woods and irons They have something in common in that they have special characteristics compared to the above, and it is thought that there are probably hundreds of types currently on the market.

The designs, materials, and structures of these devices are truly diverse, and each has its own characteristics and selling points, but in the end, they are all very similar, and there is no so-called ``decisive factor'' like the present invention. .

A summary of drivers from the above overview and the perspective of this section is as follows.

(1) Drivers naturally have long shafts and low lofts due to their original purpose, so it is well known that it is extremely difficult to make full use of them.

In general, the length of the shaft and the directional stability of the ball are at odds with each other, and the stiffness of the shaft is closely related to the swing speed.

In order to solve these problems, various improvements have been made both at home and abroad, both in terms of club shafts and heads, but the current situation is that none have achieved satisfactory results. .

(2) Regarding the club face, there is a face that corrects the fly ball when it misses the sweet spot and hits the ball.
There is a "slice" on the face as a countermeasure for curve (camber) and the direction of the ball depending on the player's arm strength.
There are three types: , ``hook'', and ``straight (square)''.In addition, in order to increase the flight distance, there are 3 types: 7-8 degrees to 11-8 degrees.
It has a loft of about 13 degrees.

However, with conventional golf clubs, whether it's the loft or the face angle, these are all unique and fixed to each club, so when playing in strong wind and rain, you may have to go up the tee, or conversely, set the tee high. Even if I tried to make a nice shot by trying various things with my arm and technique, such as changing the way I swing or changing the way I swing, I could only expect results to a certain extent.

However, it is impossible to achieve the same effect as adjusting the face angle or loft by simply adjusting the club head on the fairway or green just before the shot. .

(3) When considering the instantaneous energy applied to the ball at impact, considering only the club side, in principle it is given as the product of the mass of the head and the speed at impact, but in reality it is the product of the club shaft. There are also differences in the flight mode of the ball depending on the involvement of deflection, shot mode, and deformation strain energy on the ball side.

Also, in order to extend the flight distance, the ball must be hit at the bottom of the swing arc, at the lowest string, and the key is how to swing widely across the bottom of the arc. .

In other words, even if the same bullet is fired with the same amount of cartridge propellant, there is a difference in the flight distance and hit rate between a short gun such as a pistol and a long-barreled rifle. It seems to be a way of thinking or a theory.

From this perspective, so-called "metal woods" have recently become a hot topic in place of traditional wood clubs, with the catchphrase "flying well and not bending", and their selling point being the club head. Because the inside is hollow, the face has a trampoline effect, which allows for good contact between the face and the ball, and has a great effect of rebounding the ball, which in turn contributes to accuracy. It is said that

However, considering the structure of the trampoline head, the trampoline effect mentioned here does not apply to existing metal wood or traditional wood.
Although it is a driver, it is assumed that a special club with a hollow part on the back side of the face cannot be expected to produce any significant effects in reality.

(3) Features and outline of the present invention: The features and outline of the present invention are explained below with reference to the drawings (Attachment II).

[Note]: This application is related to "basic patent",
Industrial property rights in structural details, so-called "peripheral patents"
A separate application is currently being filed.

The concept of the present invention has already been covered in Section 2 “Claims” and Section 3/3.
As stated in section (1) "Concept of the present invention", a specific explanation thereof is as follows.

(1) The biggest feature is that the club face (2), which makes up the club head (1), which was originally thought to be integral in the conventional concept, is separated from the main body, and a spring with an appropriate spring constant is used. Since it is connected to the main body as an independent suspension mechanism via 3, the trampoline effect acts like a booster, dramatically increasing the flight distance of the ball.

The reason why metal woods, which have become a hot topic recently, fly is because the inside of the head is hollow, so the impact causes the face to dent inward, similar to a trampoline, and because of this, the face and ball It is said that the closeness of the ball is good and the effect of repelling the ball is great, which in turn leads to accuracy.

However, the trampoline effect created by hollowing out the inside of the head, which can be seen in conventional metal woods and some wood drivers, is theoretically, but in reality, compared to some norid heads. Therefore, it can be imagined that there is only a slight effect when viewed relatively.

In addition, in order to increase the flight distance of the ball, and to increase the repulsive force, the material of the face is made of compressed synthetic material made of wood fibers hardened with synthetic resin, and recently, carbon fiber, which is the material of the black shaft, is used as the material of the face. Composite heads made of graphite and FRP have been adopted, but these are both in name and in reality a ``static'' measure to increase flight distance.

On the other hand, in the case of the club head of the present invention, it literally has groundbreakingly strong "dynamic" power.
It is no exaggeration to say that it is a "up device".

The impact mechanism is that the moment the ball hits the face, the moment the ball's deformation strain reaches a certain limit,
Face: 2 is also compressed to the gap inside the head: 4,
At the same time, the energy (EPS: POWER SPRI)
The energy stored in the NG is stored in four springs interposed between the face 2 and the head body 1.

↑ Strictly speaking, the deformation and strain of the ball has reached its limit■
Around the same time, the inertial capacity (EH) of the club head 1 and the deflection energy (ESH) of the shaft are combined with the energy (ESP) of the spring 3 mentioned above, and the energy thrust from the club side (EC) is obtained. Furthermore, the deformation strain energy (EB) of the ball itself is added to this, resulting in a total explosive force (ET) due to a trampoline effect that is incomparably stronger and more reliable than conventional metal heads.
As ET=EC(ESH+EH+EPS)+EB]-, an extremely strong synergistic repulsive force is exerted on the ball.

(2) The second feature is that the strength of the spring 3 can be easily adjusted, thereby adjusting the flight distance of the ball and even adjusting the trajectory.

Originally, this spring depends on the player's strength, swing mode, shaft material, club type, etc.
Naturally, their strength (spring constant), dimensions, materials, etc. are different, but
Each club itself is essentially unchanging and unique.

In the present invention, this spring, which should originally be unique to each club, can be compressed or expanded by adjusting the cylinder screw 5 connected to it with the training edge 6 of the head. The idea is to be able to adjust the repulsive force to some extent.

In other words, another feature of the present invention is that even with the same club, the flight distance and flight path of the ball can be adjusted to suit the course and other environmental conditions at any given time. It is.

In this case, if you adjust the four springs A, B, C, and D uniformly, you can adjust the flight distance without changing the trajectory of the ball; Or A, D and B,
By adjusting each pair of C individually, the club,
It can produce the same effect as changing the head loft or face angle, and its major feature is that these adjustments can be made easily and easily even just before the shot.

In other words, by increasing the repulsive forces of A and B, or by weakening C and D, the springs on the A and B sides are made relatively stronger compared to the C and D sides. Therefore, the effect is the same as reducing the loft angle, and the ball that is impacted in this state will fly on a lower trajectory than before the adjustment, resulting in a longer flight distance.If the opposite adjustment is made, the ball will fly on a trajectory with a larger elevation angle. , the effect increases or decreases depending on the degree of adjustment.

Also, if you adjust the strength of the A and D sides to be relatively strong compared to the B and C sides of a face that was in a "straight (square)" state, it will effectively become a "hook face",
At impact, the ball will take a more leftward path than before the adjustment, and if the ball is reversed, it will result in a "slice face."

Furthermore, the location of the four springs depends on the type and purpose of the club, the player's preferences, the design philosophy, etc., and ultimately the absolute strength of each spring is determined. Depending on the situation, A, B, C,
A' shifted by 45 degrees from the position of D (X method)
, B', C', and D' (10 types).

In the case of these ten methods, adjusting one spring A' will have the same effect as adjusting two springs A and B, so consider cases where adjustments are made during the course, especially just before a shot. Although the ten methods are obviously easier and more convenient,
Which one you choose depends on a case by case basis; the effects are exactly the same no matter which one you choose, and both can be expected to produce excellent effects.

Incidentally, the adjustment mechanism using the cylinder screw 5 is very convenient and can be used in a variety of ways, but compared to one without such an adjustment mechanism, the mechanism is of course It gets a little complicated.

This is also a cost increase factor, so in some cases, the adjustment mechanism using screw 5 may be eliminated.
Of course, it is also possible to use springs specific to each club semi-permanently.

When replacing springs using this method, you can adjust each spring as needed in the same way that you disassemble the head and adjust the weight to balance a traditional wood club head. The purpose can be achieved by replacing 1 to 4 pieces as appropriate.

(3) Thirdly, it is a feature of the present invention that the entire surface of the club face can be called the sweet spot area.

When you hit the ball at or near the center of the face, even if you make the same shot, this club will have a much straighter, bullet-like liner than a conventional metal wood. However, even if the ball is off the center of the face, if it hits somewhere on the corner of the club face, the ball will fly as far as if it were hit in the sweet spot area. You can see.

That is, if the ball were to hit at point P within the range connecting points A, B, C, and D, the ball would hit points P, A, B, and It flies in the direction of the resultant vector of the spring strengths that are inversely proportional to the distances PA, PB, PC, and PD connecting points C and D.

Also, if the ball is hit at point P' outside the area connecting A, B, C, and D, the ball will hit P'A, P'B, P' in principle, as in the case of point P. It flies in the direction of the resultant vector that is inversely proportional to C and P'D, but in this case, the repulsive force of the springs B and C is 0, and rather the direction that restrains the movement of the face surface at points B and C. Therefore, the resultant vector that is involved in the flight direction of the ball acts as a relatively stronger corrective force in the front direction than in the case of point P.

Therefore, in contrast to the so-called static direction correction force of conventional metal woods, the club head of the present invention is characterized by a club face that can properly be said to be "dynamic", and the entire club face is It is like a sweet spot, and it can be called a ``magic golf club'' that guarantees a long distance toward the target no matter where you hit the ball on the square face.

Additionally, as per Section (3) in general, the material for the main body of this club/head can be selected from a wide range of materials, from conventional woods such as Persimmon to light alloy castings with low specific gravity. .

In other words, do you choose a traditional orthodox wood club, even if it requires a little more man-hours and is more expensive, or do you choose the latest metal head that benefits from recent advanced materials and processing technology? Although there are advantages and disadvantages, objectively the latter is better in terms of production costs, and when it is realized, it is believed that it will become a revolutionary golf club that will go down in the history of golf at home and abroad.

(4) Expenses or effects of the present invention: Based on the above explanation, it is already clear that the effects of using the present golf club are excellent in terms of flight distance and directionality. .

Furthermore, in that these can be adjusted freely, it can be said that it is the emergence of a ``revolutionary new weapon'' to replace the recently emerging metal wood, and depending on the situation,
Since its appearance in 1898, due to the dramatic increase in flying distance,
It was all the rage at the time and completely changed the course concept up until then.
It is conceivable that it will have an influence comparable to that of the ``Haskell Ball,'' which has a name in world golf history.

Here, we will discuss the direct effects brought about by the present invention, and
The main points regarding the secondary ripple effects are listed below.

(1) With the revolutionary increase in flight distance of the ball and the stabilization of direction, it is often possible to hit the ball in two even on long holes of nearly 500 yards, which not only improves the score but also improves overall performance. The course can be developed with plenty of time to spare.

(2) The same effect as adjusting flight distance, loft, and face angle can be obtained very easily, so it can be used under various environmental conditions when playing in strong winds or in the rain. Depending on the situation, you can use this club to make flexible shots in areas that cannot be covered with your arms or skills, allowing you to develop the course to your advantage.

(3) Regarding the flight direction of the ball, compared to the "static" direction correction method of conventional metal woods, the club head according to the present invention has a correct "dynamic" club face. No matter where you hit the ball on the face, you can expect it to fly accurately toward the target and fly a long distance.

(4) The recent development of electronic technology, including micro-computers, has been remarkable in all fields, and golf shot simulators have also been developed and commercialized. By selecting and installing an appropriate spring, it becomes possible to fly the desired flight path fairly accurately.

This allows players to advantageously develop hole strategy strategies that suit the course.

In other words, recent golf practice simulators can simulate and display the head speed, flight distance, face angle, hitting area, ball launch direction, etc. that are related to the flight distance for each shot. By applying this technology, it becomes possible to select springs with repulsive force suitable for various adjustment purposes with considerable precision.

In other words, the player can fly the ball fairly accurately along the flight path desired in advance.

To summarize the above specification of this application, until now, several "magic clubs" have appeared and disappeared in the world as words expressing the excellence of drivers and putters, but this club By realizing this, it becomes possible to fly the ball over long distances that were previously thought to be impossible, and more accurately than expected.

In other words, the player says that the flight distance of the ball he hit has increased to such an extent that he has no idea where it went, and while searching for the ball, he finds his ball further away than he expected, in the middle of the fairway. Situations like these are occurring in various places, and it seems that the time will soon come when the world's concept of golf courses will change.

Furthermore, with modern technology, there will be no problem in commercializing and commercializing this golf club, and decision-making means the first step to materialization, and once materialization takes place, it will be done correctly. As a "magic club," it is expected to meet the expectations of golfers around the world, both amateurs and professionals.

This will not only contribute to the spread of golf at home and abroad and the development of related industries in Japan, but also contribute to the country in terms of foreign exchange, which is expected to deteriorate in the future.
