Description

A golf club head for driver and fair way}

The present invention relates to a club head of a golf club mainly used for drivers and fairways, and more particularly, by processing the face member to easily adjust the angle of the shaft neck according to the physical condition of the player, the stability of the address (address) The present invention relates to a golf club head for drivers and fairways, which can increase the distance and improve the accuracy of the direction.

In general, unlike other sports, golf is a sport that responds very sensitively depending on the driving shot posture, swing form, the length of the pole, and the grip state of the grip.

Golf clubs for hitting golf balls are drivers for sending golf balls over long distances, irons for fairing to greens, and hitting golf balls with relatively little force on the green. It is divided into putters for insertion into holes.

In golf, the choice of golf clubs is as important as the address and swing form of golf clubs for players to improve their playing performance. In particular, where the center of gravity of the head affects the weight of the club head, which accounts for a large portion of the golf club's weight, and the driving characteristics of the ball, and whether the golf club is suitable for the physical condition of the player, Has become an important key to improving In order to maximize the distance of the golf ball, the center of gravity of the ball and the head and the contact point on the outer surface of the ball in contact with the face of the club head when hitting should be in a straight line. Since the ball hitting point should be 45 ° below the ball's center of gravity. This is because the flying direction and flying distance of the golf ball are greatly influenced by the moving direction of the head and the hitting point position of the ball at the moment of hitting the ball. Therefore, when the golf club does not match the physical condition of the player itself, it becomes a slice shot or a hook shot, so that the golf ball cannot fly in the desired direction.

The distance of the golf ball is also related to the thickness of the face surface of the club head. In other words, the thicker the club head, the greater the sponge (spongy) effect, the shorter the distance of the golf ball naturally, the greater the reverse. However, when the thickness of the face surface becomes thin, cracks or breakages may occur due to fatigue phenomenon due to intensive strike or brittleness due to injection molding of the club head, and thus may have a predetermined strength to withstand the impact load and The thickness having hardness is selected.

In particular, the flight direction of the golf ball is greatly affected by the direction of movement of the head at the moment of hitting the ball, the position of the hitting point of the ball, and the shape of the club head also affects the flying distance and the directionality.

Conventional golf club head 100, as shown in Figure 1, consists of a curved surface having a predetermined radius of the roll (R ₁ ) and the radius (bulge R ₂ ), a plurality of grooves ( Face member (101) is formed to hit the golf ball 101a is formed; Crown member 102 having a curved surface curved by a predetermined radius, one end of which is coupled to the upper surface of the face member 101 and serves as a weight to effectively transmit impact energy due to the hit to the golf ball. Wow; A cylindrical shaft neck 103 installed at one end of the crown member 102 in a state of forming a face angle with the face member 101, and connected to the shaft; It is composed of a sole member 104 in contact with the ground and connected to the face member 101 side from the lower portion of the crown member 102 to guide an accurate impact. In addition, the space formed by the combination of the crown member 102 and the soul member 104 is filled with a filler such as a polyurethane foam to prevent the hitting portion is deformed by the external pressure generated when hitting the golf ball.

Herein, a plurality of grooves formed on the outer surface of the face member 101 allow a bite or spin to be generated when the ball is controlled, and also a hitting surface and a batting ball. It is to improve the flying distance and the direction by reducing the contact area with.

In addition, the club head 100 has a variety of angles to have a flying distance and direction, which is the angle of inclination of the face surface with respect to the vertical plane as shown in the right side view of the club head of Figure 2a The angle θ ₁ , and as shown in the plan view of the club head of FIG. 2B, the angle between the face surface and the shaft neck is called the face angle θ ₂ , and the front view of FIG. 2C. The angle of the sole surface and the shaft of the club head as shown in Fig. ₂ is called a lie angle (θ ₃ ), and in the face member, the face face is rounded as shown in the right side view shown in Fig. 2A. (The face face is convexly rounded when viewed from the side) is called roll R ₁ , and the face face is rounded as shown in FIG. 2B (The face face is convex when viewed in plan view.) Rounded shape) as a bulb (R ₂ ) I say.

The club head configured as described above has various problems, which are listed as follows.

First, since the face surface of the front member 101 is subjected to a lot of impact, not only has a thicker structure than the other surface in order to give strength enough to withstand the impact caused by the impact load, but also to the face surface Since there is no device for absorbing the impact to be applied separately, it is usually a structure that distributes the impact load over the whole of the head surface, which has a problem of shortening the flying distance. That is, the thickness of the face member 101 formed thicker than the other surface to give the strength of the face surface generates a sponge effect (hit load absorbing effect) to reduce the repulsive force to shorten the flying distance. In addition, the dispersion of the impact load transmitted to the other member through the face member of the club head acts as a cause for dispersing the intrinsic weight of the club head, which results in the depth of repulsive force is not concentrated in the center, but dispersed in various directions. Causing. Loss of power due to hitting as much as the rounded portion of the top and bottom of the club head. That is, when the a-a straight line and b-b straight line shown in FIG. 3A, the c-c straight line and the d-d straight line shown in FIG. 3B, and the e-e straight line shown in FIG. The rounded part becomes a loss part of power, and the flying distance is shortened by the power loss part.

Second, as shown in Figure 3a, the ratio of the length (l) of the side of the face of the face member 101 and the head width (d) from the face member 101 to the rear end is about 1: 0.8. The repulsion depth of the impact force according to the impact load has a problem that acts as a limiting factor for the distance.

Third, the bulk and the roll of the face surface cause a slice flight or a hook flight, there is a problem to decrease the orientation. This means that at the moment of hitting, the face face of the head does not form a right angle to the direction of movement of the head, but is open outwardly or close inwardly, so that the center of gravity of the ball and the point of impact of the ball This is because there is no coincidence and a spin in the left and right directions occurs in the ball.

Fourth, since the shaft neck is attached to the club member's crown member at a fixed angle, the sole of the head does not come into close contact with the ground depending on the physical condition. It was very difficult to have a problem causing slices or hooks.

Therefore, the present invention has been proposed to solve the above problems, by improving the directionality by flattening the face member of the club head to form a uniform repulsive force for each hitting portion, the crown member and the sole connected to the face member It is an object of the present invention to provide a golf club head for a driver and a fairway capable of removing the loss of power due to the dispersion of the impact load of the ball by making the upper and lower surfaces of the member parallel to each other.

In addition, the present invention is formed on both sides of the face surface in an angular shape having a predetermined angle of inclination, according to the physical condition so that the shaft neck is attached to a predetermined position of the inclined portion so that the contact surface is in close contact with the ground at the addressing point Another goal is to provide clubheads for drivers and fairways that can lead to sweet spots.

In addition, the present invention is provided with a hollow pipe that can extend the depth of repulsive force on the rear of the face surface to improve the distance by focusing the inherent load of the club head on the sweet spot of the face, the weight on the hollow pipe rear side Another object of the present invention is to provide a driver and fairway golf club that can improve direction by providing a device capable of adjusting the center.

In addition, the present invention to increase the depth of the repulsive force by forming the same ratio of the length of the face surface and the head width, and also to form a streamlined shape of the head to reduce the air resistance during the shot operation of the player and Another object is to provide a fairway golf club head.
