Abstract

A golf club head with high reaction is provided to reduce a shock transferred to golfer' hands through a grip, to improve a flying distance by adding the reduced power to directionality of a golf ball, and to correct bad slice and a high or a low trajectory. A golf club head with high reaction includes a face part formed in a minus sign shape by three pieces comprising a face and two pieces attached to the top and bottom of the face. The face part is formed in a plus sign shape by five pieces comprising the face and four pieces attached to four corners of the face, and in an X-shape by five pieces comprising the face, two pieces attached to the top and bottom, and two pieces attached to the left and right.

A golf club head, a metal driver, a metal wood, and an iron head. 1) Face the face,

2) "+" shape, 3) "x" shape to maximize the energy transmitted to the golf ball

To increase the distance.

When the golf ball strikes with a strong impact, the force is transmitted through the face and shaft to the hitter's hand via the grip, sometimes with an impact reaching the elbow, reaching up to 2 tons. Damage. This force is absorbed by the face and converted into repulsion, allowing the golfer to hear a refreshing sound when hitting and to deliver a soft feeling to the hand.

In Fig. 4, the low repulsive force of the spherical body is shown in Figs.

This is because the repulsion of the center of the face is fixed from above and below, so that the spherical body of FIG. 4 is splashed only by the action and reaction in physics and the elasticity of the spherical body itself.

In order to send the spherical away, the repulsive force of FIG.

In Figure 6, the left and right two repulsion axis (A, B of (Fig. 6)) the remaining pieces in the conventional manner

Argon-weld as in 2 parts (a, b). If the golf ball hits the center of the face

When the A and B parts are pulled and swinged, the moment of inertia increases

This energy is soon converted into flying distance.

(kgfms²) = ∑r² · dm dv

Between the spherical mass dm and the square of the distance r from the axis of the golf swing to the spherical body

Sum of the products r² · dm. dv is an additional index of repulsion (about 1.1)

In Fig. 6, the existing face that is springed like a spring at the amount of energy, such as the long ends (A and B) is welded entirely, as in Fig. 4, it is difficult to expect a repulsive force.

High repulsive forces and, depending on the design (positioned positions) on the top, bottom, left, and right sides, create different repulsive forces in different parts of the face, so that malignant slices or hooks correct high or low trajectories.

In Figure 7, argon welding four pieces of go, me, da, and la together with the face, complements this even if the head speed is not high when swinging due to an increase in the moment of inertia when the golf ball is hit in Aa, Ab, Ba and Bb. Many flying distances are generated.

To further increase the repulsive force, the face was separated into 3-5 pieces, which were modified to produce repulsive force just as if the arrow was lightly placed on the demonstration.

The face shape was also diversified to fit the pitch of 1) "-" form of Korean-Japanese), 2) "x" form, and 3) "+" form.

At E = mc ² , the head speed of the pro is typically c = 110 mile / hour

This can be achieved by a c = 120 mile / hour effect, which is about 10% higher.

Golf ball's direction and high flying distance can be guaranteed.

The advanced technology of golf club heads to date depends on how lightly made the sweet spot can be.

Therefore, they continue to search for light metals, and chemicals such as carbon were also incorporated into the golf club head as a substitute, which is constantly lighter (40 to 45 grams) on the shaft. .

In order to do this, the recently developed metal driver and fairway metal wood adopt the light metal and even the hollow hollow structure of the iron club head to make the volume of the golf club head. Is moderately large and proportionately allows for a large faceted face with a wider sweet spot.

Since the weight reduction and the large volume of the material are grafted in proportion to each other, products that have a thinned face surface by joining the crown portion of the carbon material to the main body have already become popular, which ultimately has been replaced with the purpose of increasing the repulsive force and widening the sweet part. .

However, due to the widening of the face, air resistance during downswing is considered, and excessively large golf club heads can be burdensome, providing a suitable volume (about 400 cc). The conclusion is that golf club heads are appropriate.

It is hard to expect high repulsion in the size of around 400cc in volume, so the producer makes thin face thickness, which does not produce the resilience as much as desired, and the noise of the batting is not clean, and the material is gradually weakened so that it will crack quickly. (crack)

The present invention is designed to have a repulsive force corresponding to the volume (400cc) of the appropriate size, and the object is to always smash in the direction that anyone wants.

Face golf club head with high repulsion

The present invention relates to a golf club, the force that hits the golf ball when hit by the golf club reaches a maximum of 2 ton. This force converts the golf ball into energy that travels forward, providing a relative distance. More efficient flying distance and want

It is very effective for sending golf ball in the direction.

When a golf ball and a golf club face collide, a strong shock wave is generated. The present invention mitigates a shock transmitted to a hand through a grip, and adds the relaxed energy to the golf ball's direction. The goal is to increase the efficiency of conversion into factors that increase the distance.

Energy is E = mc ^It is denoted by ² , the most important factor being "square of speed".

In addition to this element, it also adds a force that springs up like a spring to increase head speed. Repulsion is added.

In general, even the driver, the fairway wood, and even irons, the club head is hollow (empty center), which naturally increases the swing speed by lightening the head weight.

In Yosai, almost all of the materials of the face are titanium, because the metal itself is light and the repulsion is relatively larger than that of ordinary steel.

If the face is low density, the weight is small and the center of gravity of the golf club is moved backwards, so that the sweet spot area becomes wider, so it can be easily hit.

The golf club head improves the rebound modulus and has a wide sweet spot. By design, the malignant slice or hook is improved, allowing the golf ball to fly straight in the desired direction rather than the traditional golf club head, resulting in more than 10% longer distance. Will be.

A typical golf club head is manufactured by three welding combinations of a main body, a crown part and a face part. The head body and the crown part are obtained by casting or pressing, and the face part is press-molded, and sometimes heat-treated, and then obtained by welding to the main body. Instead of welding in one piece, the straight "-", "+" and "x" shapes

The purpose is to get a refreshing shot and flying distance by joining a face composed of several pieces to create a repulsive force.

A few piece face, in the form of a "+" and an "x", does not have any gaps in between, but just a crack (0.1 mm) Because of the following welding, no additional noise is generated.
