Golf club for preventing hook and slice

Golf club for preventing hook and slice description/claims

Applicant claims foreign priority under Paris Convention and 35 U.S.C. §119 to the Korean Patent Application No. 20-2007-0000499, filed Jan. 11, 2007 with the Korean Intellectual Property Office.

1. Field of the Invention

The present invention relates to a golf club for preventing a hook and a slice, and more particularly, to a golf club for preventing a hook and a slice, which has a sole plate of a bottom area and a sole progression of a side width of the club head are smaller than those of a club head of a prior art by cutting a part of the rear side of the club head, thereby reducing a weight of the club head and reducing a friction force between the ground and the club head so that a golf ball can unthread a rough or sands, and allowing a golfer to easily swing the golf club, and which a swing bar is mounted at the cut part of the club head to move a weight center of the club head backwardly so that a driver distance is increased and a resistance to the air is minimized by keeping a balance of the club head during a swing motion, thereby minimizing a bending and a twisting of a shaft.

2. Background Art

In general, golf clubs are classified into drivers used for longer shots and irons used to propel a golf ball to approach a hole. As shown in FIG. 1, such a golf club 1 includes a club head 2, a shaft 3 extended from the club head 2, and a grip formed on an end of the shaft 3 to allow a golfer to grasping the golf club 1.

The golf club 1 has a structure that the club head 2 with a heavy weight is connected to an end of the shaft 3, wherein a weight center of the club head 2 and a sweet spot of a club head face (F) are deviated from an extension line of the shaft 3. When the golfer hits the golf ball using the golf club 1, strength of inertia is varied according to a weight of the club head 2, and it causes backward bending and twisting of the shaft 3 of the golf club 1. When the backward bending and twisting of the shaft 3 are caused by the weight of the club head 2, the club head face (F) of the club head 2 is not at a right angle to the golf ball but opened toward the outside or the inside.

That is, when the golf ball is located on the club head face (F) at the right angle, the golfer can hit the golf ball to a wanted location, and so, a driver distance is also increased. However, to accurately hit the golf ball to the wanted location and distance, after the golfer grasps the golf club 1, the golfer swings the golf club 1 in such a manner as to remove the bending and twisting of the shaft 3 of the golf club 1 by converting an acceleration motion into a uniform motion of the club head 2 on a swing plane at a time point that the club head 2 hits the golf ball on the swing plane of the golf club 1.

Next, to hit the golf ball to the wanted location and distance, the golfer locates the club head face (F) of the club head 2 to be a right angle to a wanted direction. However, it is difficult, even for skilled professional golfers, to exactly know the time that the club head 2 of the golf club 1 hits the golf ball, and so, it is more difficult for amateur golfers. Therefore, many golfers are in anguish about a hook and a slice, which are caused by the bending and twisting of the shaft 3 according to the weight of the club head 2.

In addition, as shown in FIG. 1, since the golf club 1 according to the prior art has a wide sole plate 5, which is a bottom area SL1 of the club head 2, and a wide sole progression 6, which is a side width S1 of the sole plate 5, when the golfer swings the golf club 1, a friction force is increased due to a friction area to the ground and the sole plate 5 and the sole progression 6 are formed largely, so that the weight of the club head 2 is increased and the bending and twisting of the shaft 3 are frequently generated when the amateur golfer swings the golf club 1, whereby a unstable swing motion is made. Therefore, it is obvious that the hook and the slice are frequently generated due to the bottom area SL1 of the sole plate 5 and the weight of the club head 2 when the amateur golfer who uses the golf club of the prior art 1 swings the golf club 1.

For your understanding, the hook and the slice will be described in brief. First, the hook describes a ball flight in which the golf ball curves from the right to the left due to a counterclockwise rotation thereof, and frequently occurs in case where the club head hits the golf ball while moving from the inside to the outside when an impact is generated due to the golfer's swing motion.

In the meantime, the slice describes a ball flight in which the golf ball curves severely to the right of the line of flight since it bends to the right, and occurs in case where the club head hits the golf ball from the outside to the inside when an impact is generated due to the golfer's swing motion. So, the hook and the slice are problems that many golfers must solve.

In other words, if the time point to stop acceleration for the impact is early when the golfer swings the golf club to hit the golf ball, the club head of the golf club is shut and the hook occurs. On the contrary, if the time point to stop acceleration is late or acceleration is not stopped, the club head is opened and the slice occurs, so that out-of-bound in which the golf ball flies highly and misses its target (hole) while bending to the right.

Therefore, to solve such problems of the hook and slice, many golfers make efforts to minimize the hook and the slice through a posture correction and various methods, and so, various posture-correcting devices and golf clubs have been disclosed. However, such posture-correcting devices are very expensive, but do not greatly prevent occurrence of the hook and slice. Moreover, various golf clubs have been disclosed, but still have the problem in that the hook and slice frequently occur since there is a restriction in lightening of the weight of the club head due to a problem related with the driver distance generated when the golfer hits the golf ball.

Of course, not only the amateur golfers but also the professional golfers suffer from the occurrence of the hook and slice. The professional golfers can solve the problems of the hook and slice somewhat only by selecting the golf club suitable to his or her own self needless to greatly concern about selecting the golf club. However, the amateur golfers may experience a severe difference in occurrence of the hook and slice according to the selection of the golf club. So, many golfers need a golf club which can greatly prevent occurrence of the hook and slice.

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a golf club for preventing a hook and a slice, which can allow a golfer to easily control the golf club while swinging the golf club since a sole progression having a side width extending backwardly from a club head face and a sole plate having a bottom area are formed small by cutting a part of the rear side of a club head, thereby preventing the hook and slice due to a light weight of the club head and minimization of a frictional area between the ground and the club head.

It is another object of the present invention to provide a golf club for preventing a hook and a slice, which can allow the golfer to easily swing the golf club by minimizing a frictional resistance to the air during the golfer's swing motion and allow a golf ball to easily unthread a rough or sands due to the small area of the sole plate since a swing bar is mounted at the cut part of the club head.

It is a further object of the present invention to provide a golf club for preventing a hook and a slice, which can minimize the bending and twisting of the shaft since the swing bar mounted at the rear side of the club head moves a weight center of the club head backwardly to keep a balance of the light-weighted club head, thereby preventing the hook and slice to the maximum.

To accomplish the above object, according to the present invention, there is provided a golf club for preventing a hook and a slice, which includes a club head face for hitting a golf ball, a sole plate having the bottom face contacting with the ground, a toe outwardly formed at a side of the club head face, and a heel formed curvedly at the other side of the club head face, golf club comprising: a cut part formed at a part of the rear side of the club head to reduce an area of the sole plate having the bottom area contacting with the ground; coupling holes respectively formed on the toe and the heel of the club head face of the club head, each coupling hole having a stepped jaw; a ring-shaped swing bar having female screws formed at both ends thereof, the swing bar being mounted at the cut part of the rear side of the club head to keep a balance and compensate for a weight of the club head, and being fittingly combined to the club head from the rear side of the club head toward the club head face in such a manner as to be caught by the stepped jaws of the coupling holes; and coupling bolts respectively fittingly combined to the coupling holes from the club head face toward the rear side of the club head to fix the swing bar to the club head, and screw-coupled to the female screws formed at both ends of the swing bar.

Moreover, it is preferable that the size of the club head having the cut part does not exceed a half of the size of the club head of prior arts.

In addition, it is also preferable that the swing bar has male screws formed on the outer peripheries of both ends thereof, the ends of the swing bar are respectively fittingly combined to the coupling holes formed on the toe and the heel of the club head, and cap bolts respectively having female screws are coupled to the male screws of the swing bar to fix the swing bar to the club head.
