Description

Face for golf driver {FACE FOR GOLF DROVER}

The present invention relates to a face for a golf driver, and more specifically, increases the accuracy and repulsion that can hit the ball at the sweet spot to increase the flying distance, as well as improve the directionality to prevent hooks or slices, so that a stable score can be achieved. It relates to the provision of a face for a driver that can provide excellent feel.

In golf, a tee shot is performed using a driver at the tee box, and then the second and third shots or approaches are performed using woods, irons, utility clubs and wedge clubs to seat the ball on the green, and then use the putter to play the green. In the form of finishing one hole by putting it into a hole formed in

A club used for the first time in a tee box to perform such a golf sport is a driver, and the configuration of the driver 100 will be described with reference to FIG. 1 as follows.

A typical driver 100 includes a head 101 that substantially strikes a ball, a shaft 103 to which the head 101 and the tip end 102 are coupled, and a butt end 104 of the shaft 103. It consists of a grip 105 that allows the player to swing by holding the club by hand.

The head 101 has a flat sole 106 on its bottom surface and a head body 108 connected with a round crown 107 on its upper surface, and a real ball is placed in front of the head body 108. It is configured by connecting the striking face (110).

The face 110 forms a roll 111 in a round shape from the top to the bottom and a bulge 112 in a round shape to the left and right, and the roll 111 and the bud 112 The central position of the sweet spot point 113 becomes the sweet spot point 113 , and a certain part around the sweet spot point 113 is called the sweet spot area 115 .

The driver as described above is a situation in which various types have been developed and used in the prior art. A typical example is as follows through the patent literature.

Patent Document 1, the body; and a striking member disposed on the front surface of the body and hitting a golf ball;

The striking member is made of a synthetic resin material that is more flexible than the body,

It is characterized in that it is configured to engage with each other by forming a concave-convex portion on the front portion of the body of the head and the rear portion of the striking member.

Patent Document 2 discloses a driver head formed by forging,

a face provided in the front and having a face surface for striking a golf ball;

a hosel coupled to a shaft provided with a handle gripped by the player on the upper side;

a crown and a sole extending rearward from the face to form upper and lower portions;

a heel and a toe respectively disposed between the crown and the sole of the rear side of the face;

The face and the hosel are integrally formed by forging so that the heated raw material is placed between the forging upper mold and the forged lower mold of the press to lighten it, and the extra weight is distributed to the rear part of the head to achieve a lower center of gravity of the head. Molded, the rear of the face is characterized in that the lower end of the hosel is formed convexly downward toward the rear of the face, and there is no part in which the edge of the face surface extends rearwardly near the hosel.

None.

When hitting the ball with the driver as above, hitting the ball with the sweet spot maximizes the reaction force and can send a long distance, keep the direction right, and reduce shock and vibration to prevent damage to the club and prolong the life of the user. It is possible to reduce the physical burden on the players and to improve the feel.

However, when hitting the actual ball, it is difficult to accurately hit the sweet spot, and moreover, hitting the exact sweet spot point is 1/40,000.

For this reason, the technical part of golf exercise accounts for 20% and the mental part occupies 80%, so it is called that the swing and striking power are influenced by the psychological state or mindset of golfers.

As mentioned above, it is not possible to align the regular hitting, so the ball hits the upper and lower sides of the face, including the heel and toe parts of the face. As this leads to distance loss, it also affects the second and third shots, making it impossible to get a good score.

Especially in the case of senior and female golfers, since they do not have power and speed, it is even more difficult to hit the sweet spot on a regular basis.

When the ball is hit by the buzz that forms a round in the left and right directions of the face and the roll that forms a round in the up and down direction, the gear effect ensures that the ball is always compensated in the target direction. If this does not occur, this gear effect cannot be obtained, so the above-mentioned seniors, female golfers, or golfers without power cannot guarantee straight hit and straightness.

Due to this, various problems are occurring, such as giving inconvenience to many golfers, such as making it difficult to perform address and swing movements normally due to the mental breakdown of users and the induction of the yips phenomenon, which is reluctant to use a driver.

Accordingly, the present invention was invented to solve the above problems, and it is coupled to a head 101 that strikes a ball, a shaft 103 coupled to the head 101, and a shaft 103 so that a player can use the club consists of a grip (105) that is gripped by hand to allow swinging;

The head 101 includes a head body 108 connected by a sole 106 formed on the bottom surface and a crown 107 formed on the upper surface, and a face connected to hit the ball in front of the head body 108 . (110) and the face 110 form a roll (Roll, 111) formed in a round shape from the upper side to the lower side and a bulge (112) of a round shape to the left and right, and the roll 111 and a sweet spot point 113 that is the central position of the budge 112, and a sweet spot area 115 that is a portion around the sweet spot point 113;

flattening the sweet spot area 115 of the face 110 to increase straightness and flying distance;

Verges 112 and rolls 111 are formed in the heel part 116 and toe part 117, the upper part 118 and the lower part 119 of the face 110 other than the flattened sweet spot region 115. so that compensation due to the gear effect can be made when the ball is hit other than the sweet spot area 115;

By flattening the sweet spot area in the center of the driver's head face, the probability of hitting the ball with the sweet span area is increased, straightness is improved, and the distance is increased to prevent mental breakdown of golfers and to eliminate the psychological reluctance to use the driver. possible goals can be achieved.

The present invention configures the face sweet spot area of the head constituting the driver in a flat structure so that when hitting the ball, the flying distance can be increased while ensuring straightness (direction) when hitting the sweet spot area without accurately hitting the sweet spot point. have an effect

The sweet spot area of the face is flattened to ensure the straightness and flying distance, and it is configured to have a budge and roll on the outside of the sweet spot area. It has various effects, such as reducing the burden on golfers from using the driver by allowing the compensation action to occur as it is.

A typical driver 100 includes a head 101 that hits a ball substantially, a shaft 103 to which the head 101 and the tip end 102 are coupled, and a butt end 104 of the shaft 103 . It consists of a grip 105 that allows the player to swing by holding the club by hand.

The head 101 has a flat sole 106 on its bottom surface and a head body 108 connected with a round crown 107 on its upper surface, and a real ball is placed in front of the head body 108. It is configured by connecting the striking face (110).

The face 110 forms a roll 111 in a round shape from the top to the bottom and a bulge 112 in a round shape to the left and right, and the roll 111 and the bud 112 The central position of the sweet spot point 113 becomes the sweet spot point 113 , and a certain part around the sweet spot point 113 is called the sweet spot area 115 .

In the present invention, the sweet spot region 115 of the face 110 is flat, and the heel part 116, the toe part 117, and the upper part of the face 110 other than the flattened sweet spot region 115. The bristle 112 and the roll 111 are formed in the 118 and the lower part 119 to compensate for the gear effect when the ball hits other than the sweet spot area 115 .

The size of the sweet spot area 115 to be flattened is suitable for a diameter of about 30 - 40 mm. If it is smaller than this, there is no effect due to flattening, and if it is larger than this, correction of the ball cannot be made through the gear effect. can't

On the surface of the face 110 except for the flattened sweet spot area 115, the correction to direct the ball in the target direction through the gear effect is made more smoothly and frictional contact with the ball is increased. It is also possible to further form a groove 120 for the.

The groove 120 can be implemented in various ways, such as an arc shape, a straight line (horizontal or vertical) shape, an oblique shape, a V shape, etc. It is also possible to form the groove 120 in the flattened sweet spot area 115 It would be natural.

The thickness T of the sweet spot region 115 may be formed thinner than the thickness T1 of the face 110 in order to increase the repulsive force, and the central portion of the sweet spot region 115 is smaller than the thickness T2 of the edge position. The thickness T3 may be finely made thin.

The sweet spot area 115 and the boundary point 125 of the face 110 may maintain the angular connection state as it is, but when the ball hits the boundary point 125, it is possible to minimize heading in an unintended direction. It is better to connect it with a smooth round to make it possible.

The operation and effect of the face for a golf driver to which the technology of the present invention is applied as described above will be described as follows.

The use of the driver 100 is, as is well known, the backswing after the golfer holds the grip and takes an address from the tee box. Backswing top, legging, impact and follow-through are made at a glance to create a swing that hits the ball.

In this process, as illustrated in FIG. 7 , when the ball is hit with the sweet spot region 115 of the face 110, the ball can be applied and sent away without any resistance, in the present invention, the sweet spot region 115. Because of the flat configuration, when the ball is hit in the sweet spot area 115 from the sweet spot point 113 as a starting point, the ball can be sent correctly due to the flat characteristic.

In addition, by differentiating the thickness of the flattened sweet span region 115 from the thickness of the face 110 at a position other than the sweet spot region 115 to increase the reaction force, it is possible to increase the flying distance when hitting the ball.

Due to this, the obsession for golfers to accurately hit the ball at the sweet spot point 113 disappears, so it is possible to operate the driver more smoothly, and because the golfer swings in a psychologically stable state, the ball is placed in the sweet spot area 115. It will be easier to fit.

And even if the ball does not hit the sweet spot area 115 in the swing process and does not hit the other face 110, it is compensated by the roll 111, the wedge 112, and the groove 120 originally formed on the face 110. This has a gear effect in which the ball is directed in the target direction.

In this way, if you swing with a driver, the probability of hitting a regular hit increases and the distance can be improved.

In the present invention, application to a driver is exemplarily described, but it will be natural that it can be applied to a fairway wood or a utility club similar to a driver.

As described above, the present invention flattens the sweet spot area in the center of the driver's head face to increase the probability of hitting the ball with the sweet span area while improving straightness while increasing the flying distance to prevent mental breakdown of golfers and psychologically reluctant to use the driver. It has advantages such as being able to exclude the Ips phenomenon.
