Description

Golf club connection {The golf club connection}

The present invention relates to a connector for a golf club, and more particularly, to ensure that the head face of the club head is placed directly under the hand holding the grip even when the shaft becomes a hand first naturally inclined in the target direction in the address state. By disassembling the club head and the shaft and reassembling it with the connecting means that the lower end of the shaft is inclined toward the back of the club head, the hand and the head face are visible at the time of addressing so that it can be easily aligned in the target direction. The short iron is hook prevented, the middle iron, long iron, wood and the driver is a golf club connector that can be fitted (fitting) the existing golf club by conveniently adjusting the direction of the connecting means back and forth to prevent the slice will be.

Typically the golfer controls the swing of the golf club, but at the moment the clubhead acts as if the mass moves freely at a certain speed. Most of this moving mass's energy is transferred to the golf ball for a short time so that the ball compressed by the club face will bounce back to return to its original spherical shape. Maximum energy transfer and desired flight and trajectory of the golf ball are obtained when the golf club head shots the golf ball at the club's "sweet spot" point.

It is very difficult for an experienced and experienced golfer to hit a golf ball in a sweet spot of a golf club continuously, or the golf club will be distorted if it is not able to hit the sweet spot. When the club face twists, the amount of energy delivered to the golf ball is less than the maximum, resulting in a shorter flight distance, which can cause the golf ball to deviate from its ideal flight path.

The club head of the iron golf club is provided with a head face having different loft angles to float golf balls for each iron club, a tow of a large area is provided at the front end of the head face, and an area of the head face gradually becomes at the rear end. The narrowed heel is provided, and the end of the heel is provided with a hosel to which the shaft is connected. The hosel has a lie angle so that the shaft tilts toward the golfer in the addressed state.

The clubhead of most iron golf clubs has a hosel in front of the headface. In Korean Patent No. 142406, Domestic Patent No. 893315, Domestic Publication No. 2003-0074731 and Domestic Publication No. 2009-0012052, the hosel is positioned ahead of the head face. When the hosel is in front of the headface, the grip is in front of the clubhead in address state, so the handpiece is naturally maintained. If you are a hand first, you can hit the golf ball down the swing during the swing, which is advantageous in terms of backspin or flying distance.

However, novice golfers, weak female golfers and senior golfers have difficulty swinging the golf club down. When swinging a golf club in the hand first condition, care should be taken to the wrist caulking. After swinging with the wrist bent, the golf club should be leveled with the ground to release the caulking and swing the club head with only the centrifugal force to hit the golf ball. These down-blowing swings are never easily completed. If the wrist is released early due to the lack of caulking during the swinging process, the clubhead will reach the ground first, resulting in loss of distance and the inability to send the golf ball in the desired direction. Problems such as this occur.

All putter golf clubs also have the bottom of the shaft in front of the headface or coincide for hand first. Since the putter has a small swing width, there should be no shaking of the headface in the release section. However, since the head face is placed behind the golf ball in the address state, the head face was misaligned due to the slight movement of the wrist in the process of checking the head face alignment by turning the head backward.

The present invention was developed in view of the conventional problems, and an object of the present invention is that the head face of the club head does not move away from the hand holding the grip when the shaft is in the first state in which the shaft is naturally inclined in the target direction. By disassembling the club head and the shaft so that it lies directly underneath and reassembling it with the connecting means that the bottom of the shaft is inclined toward the back of the club head, the hand and the head face are visible at the time of addressing so that it can be easily aligned in the target direction. In addition, the present invention provides a golf club connector that can be conveniently fitted to the existing golf club.

Another object of the present invention is that even if the caulking of the wrist is released early at impact in the iron golf club head head of the club head is not in the back of the hand, because the probability of hitting the golf ball on the same vertical line as the hand increases the back distance is prevented After the impact, the release section in the target direction is extended after the impact to provide a connection for the golf club to reduce the miss shot, such as unintentional slice or hook.

Still another object of the present invention is to reassemble the connecting means so that the lower end of the shaft is coupled to the rear side of the club head so that the wedge and the short iron swings suddenly, the hook is prevented, and also the middle iron, the long iron, and the wood And in the case of the driver to provide a golf club connector for preventing the slide and improved orientation by reassembling by the connecting means so that the lower end of the shaft is coupled from the front side of the club head so that the slow down swing.

To this end, the present invention is a golf club connector for separating the shaft from the club head of the golf club and then reassembling them with the connecting means, the connecting means is a portion fitted to the hosel of the club head and the lower end of the shaft The fitting portions are provided apart from each other so that the lower end of the shaft lies on the rear side of the club head, and the shaft fitting portion of the connecting means has a first angle inclined toward the head face of the club head. The grip of the upper part of the shaft is characterized by being in the same vertical line with the headface.

Golf club connector of one embodiment of the present invention is to disassemble the club head and shaft in the driver, wood, utility, iron and putter golf club, reassembled by the connecting means of one embodiment of the present invention. In most golf clubs, the bottom of the shaft is adhesively fixed to the hosel portion of the club head by epoxy adhesive. Therefore, heating the hosel portion melts the epoxy adhesive and weakens the adhesive force, so that the shaft can be easily disassembled from the club head.

In the connecting means of the embodiment of the present invention, the fitting portions fitted to the lower portion of the shaft and the hosel portion of the club head are staggered from each other, and the fitting portions are connected through the connecting portion. The shaft, the connecting means and the club head are joined using epoxy adhesive so that the fitting portion into which the bottom of the shaft is fitted lies on the rear side of the club head. At this time, the shaft fitting part has an inclination angle so that the upper part of the shaft is inclined toward the head face. When the grip is held, the head face is placed under the hand, and the lower end of the shaft is on the rear side of the club head. It becomes the first state.

Downswing is important for iron golf clubs. Downswing while keeping the wrist caulking in the backswing state, when the shaft is level with the ground, the caulking of the wrist is naturally released and the downswing is achieved only by the weight of the club head.The hand holding the grip is the center of the body Being tucked in the navel, you should complete the golf club swing. When the correct swing is made, the club head presses the golf ball to compress it. At this time, the compressed ball is bounced back by the resilience force to be restored to its original state.

This down swing is possible when the shaft is tilted in the target direction in the hand first state. In the present invention, since the shaft is naturally inclined in the target direction in the address state, downblowing is possible. Also, even if the shaft is tilted in the target direction, the gripped hands and the head face are located on the same vertical line under the golfer's eyes, so there is no need to pull the wrist in front of the head face for hand first when addressing. This is prevented and the alignment of the headface in the target direction is accurate.

In addition, there is a psychological stability because the hand and the head face that hold the grip in the address state appear straight under the eyes of the golfer, and the optical illusion is reduced compared to the conventional golf club where the head face is located behind the grip. do. Especially in the case of a putter golf club, the swing width is small. In the conventional putter golf club where the head face is placed behind the grip, the head face is turned due to the slight movement of the wrist in the process of checking the head face alignment by turning the head backward. Although there is a risk of quality, in one embodiment of the present invention, since the hand and the head face are placed under the eyes, there is no need to move the head so that the alignment of the target direction is correct in the addressed state.

Also, when a beginner or senior golfer downswings to an iron golf club, the wrist's caulking is released early, so even if the club head is directed to the ground, the hand and head face that hold the grip at impact are likely to be in the same vertical line. This prevents and can directly hit the golf ball, so the distance loss caused by the back ground does not occur can help to lower the golf score.

Also, when assembling the connecting means to the golf club, the connecting portion can be assembled at the closing angle inclined toward the golfer or parallel to the target centerline of the head face or at the opening angle inclined to the opposite side of the golfer. The pushing golfer becomes a sliced pitch by opening the head face, but when the connecting means is configured at the closing angle, the sliced pitch is prevented because the head face does not open during the pushing. On the contrary, the golfer who pulls becomes a hook-like pitch by closing the head face, but when the connecting means is configured at the opening angle, the hook-shaped pitch is prevented because the head face is not closed during pulling.

In addition, the connecting means has a connection part that is bent horizontally without connecting the heel and the shaft of the club head in a straight line, so that the impact transmitted to the club during the hitting of the golf ball is canceled once at the connection part to alleviate the pain of the wrist during the miss shot. In particular, since the head face is placed under the hand, since the target direction release of the club head can be increased by 3 to 5 cm after impact, the direction of the golf ball is improved.

In addition, when the shaft fitting part of the connecting means is placed on the back side of the head face when the shaft and the club head are reassembled as the connecting means, a drastic downflow swing is possible, thereby preventing the hook from the wedge and the short iron. If the shaft fitting is placed on the front face of the head face, a smooth down swing can be performed, which prevents the slice from being in middle iron, long iron, wood and driver. Therefore, in the case of the beginner golfer has an advantage of improving the directional distance more substantially when the hook or slice is generated.

1 to 5, the connecting means for the connector 20 of the embodiment of the present invention is the hosel fitting portion 21 to be fitted to the hosel portion 14 of the club head, the shaft fitting portion to which the lower end of the shaft 30 is fitted ( 23) and the fitting portion 21, 23 is composed of a connecting portion 22 connecting the lower end of the shaft fitting portion 23 and the upper end of the hosel fitting portion 21 to be provided apart from each other. The connecting portion 22 and the hosel fitting portion 21 are constituted by a round bar, and the shaft fitting portion 23 is configured in the form of a hollow pipe so that the lower end of the shaft 30 is directly fitted. The connecting means is preferably made of a good zinc material so that the shock absorbing impact of the club head is absorbed, the spacing between the outer peripheral surface of the hosel fitting portion 21 and the outer peripheral surface of the shaft fitting portion 23 is 0.3 It is produced in the length range of mm-15 mm. In the case of a driver or wood having a long shaft length, the gap is narrowed, and the short iron and the middle iron increase the gap to favor the hand first.

The club head of the iron golf club is provided with a head face 10 in the front, the front end is provided with the highest tow 11 in the head face 10, the rear end is the lowest heel (in the head face 10) ( 12) is provided. On the back, devices for lowering the center of gravity of the club head are provided in various forms for each manufacturer. The lower part of the club head is provided with a sool 13 that digs into the ball when striking the golf ball, the upper part of the heel 12, the hosel fitting 14 of the hosel fitting portion 21 of the connecting means 20 is fitted Is provided. The hosel 14 is inclined toward the golfer such that the shaft 30 has a lie angle L.

The shaft fitting portion 23 of the connecting means 20 is inclined toward the hosel fitting portion 21 so that the grip 31 of the upper end of the shaft 30 is in the same vertical line with the head face 10. Has (H) The connecting portion 22 is basically formed in parallel with the center line CL toward the target direction of the head face 10 so that the head face 10 hits a golf ball to make a straight pitch flying straight toward the target direction. . On the other hand, the head face 10 is advantageous to a golfer who generates a sliced pitch that is pushed when the connection portion 22 maintains the closing angle C inclined toward the golfer in the direction of the target direction. When the connecting portion 22 forms the closing angle C, the head face 10 is opened at the moment of pushing the golf ball, and there is a high probability of the fitting, but the head face 10 is closed by the closing angle C of the connecting part 22. The sliced pitch is prevented because it opens in the target direction without opening.

In addition, when the head face 10 is directed in the target direction and the connecting portion 22 is inclined to the outside of the golfer by the opening angle O, it is advantageous for the golfer to generate hooking pitches. When the connecting portion 22 forms the opening angle O, the head face 10 is closed at the moment of pulling the golf ball, and the probability of fitting is high, but the head face 10 is not closed by the opening angle O in the target direction. As a result, hook property is prevented.

Golf club of one embodiment of the present invention configured as described above is compared with a conventional golf club as shown in FIG. (a) is a conventional club, where the hosel is placed in front of the headface, so when the shaft is tilted for hand first, the grip is positioned "h" away from the headface. Therefore, it is difficult to align the head face in the target direction because the club head is placed behind the hand in the address state. In addition, since the head face is placed behind the hand, the alignment in the target direction is suspected, and thus the unnecessary movement of the hand is performed in the address state, so the probability of miss shot is increased.

(b) is a golf club of an embodiment of the present invention, the shaft fitting portion 23 has a hand first angle (H) inclined in the target direction, when the grip is held in the address state, the shaft is naturally inclined in the target direction It becomes a state. The grip 31 is then placed on the same vertical line as the head face 10. Therefore, since the head face is seen directly under the hand in the address state, the head face is not easily misaligned because it is easy to align the target direction of the head face and does not need unnecessary hand movement.

In addition, even if the wrist is loosened during the downswing swing, the club head is placed directly under the hand at the moment of impact, increasing the probability of hitting the golf ball directly without hitting the ground, thereby reducing the distance loss. And the connection portion 22 has an opening angle (O) or a closing angle (C), so that the hooked or sliced pitch of golfers to pull or push is prevented. And even if the wrist is released early in the downswing swing, the clubhead is more likely to hit the golf ball in the same vertical line as the hand, preventing distance loss due to the back ground.

The connector of one embodiment of the present invention is used to improve an existing golf club. Heating the hosel 14 portion of the golf club with heat causes the shaft 30 to decompose at the club head while the epoxy adhesive melts. After cleaning the inside of the hosel 14 and the lower end of the shaft 30, an epoxy adhesive is applied to the hosel fitting portion 21 of the connecting means 20 and the adhesive is inserted into the hosel 14. At this time, the connection part 22 adheres the hosel fitting portion 21 to the hosel 14 to be parallel to the target center line CL of the head face 10 or to form an opening angle O or a closing angle C. Fix it.

Thereafter, when the lower end of the shaft 30 is adhesively fixed to the shaft fitting portion 23 by an epoxy adhesive, the shaft 30 is coupled to the club head through the connecting means 20 in a state of having a hand first angle (H).

Figure 6 applies the connection means of the embodiment of the present invention to the driver, wood and utility golf club. In the case of drivers or wood golf clubs whose shafts are relatively longer than iron golf clubs, the club head is placed on the left side of the golfer, so the club head is placed ahead of the hand with the eyes facing in the target direction. Therefore, since the golf swing is made irrespective of the hand first, it is preferable to shorten the distance between the shaft fitting portion 23 and the hosel fitting portion 21 by making the length of the connecting portion 22 shorter than that of the iron golf club. In the case of a golfer suffering from a slice, as shown in FIG. 8, when the hosel fitting portion 21 is placed on the front of the head face 10 by reversing the direction of the connecting means, the head face 10 follows the swing process. As a late open slice is prevented.

Conventionally, when the driver is held in the address state, the shaft 30 is inclined toward the target direction. However, when the connecting means 20 according to the exemplary embodiment of the present invention is used, the shaft 30 is tilted less by the distance of the connecting part 22. As there is it, there is a sense of stability.

Figure 7 shows a state in which the connecting means of the embodiment of the present invention is applied to the putter golf club, (a) is in the form of a mallet (half-moon), (b) is in the form of a blade (straight). In the case of (a), the hosel is integrally formed inside the club head and does not protrude upward, and (b) the hosel 14 protrudes toward the front of the club head.

It is more effective to apply the connecting means 20 of one embodiment of the present invention to a putter. In the case of the putter, the swing for hitting the golf ball is very small and the swing strength is weak. Therefore, it is important to minimize unnecessary wrist movements when addressing. The connecting means 20 of the present invention is easy to align in the target direction because the head face 10 is visible directly under the hand when the golf club is held at the address. In particular, the putter in the form of (b) is assembled when the lower end of the shaft 30 is fitted into the shaft fitting portion 23 while the hosel 14 protrudes forward, and the hosel 14 together with the golf ball under the hand. Visible makes alignment of the target easier

8 is another embodiment of the present invention, the shaft fitting portion 23 of the connecting means 20 is to be placed on the front of the head face (10). 1 to 5 show that the shaft fitting portion 23 of the connecting means 20 lies on the back side of the head face 10, which is advantageous for wedges or short irons. In other words, the down-swing swing is made sharply, so the head face 10 hits the golf ball at a steep slope, so it takes a lot of backspin and can increase the trajectory so that the golf ball can be sent to a desired place in a short distance. In addition, even when the club head is pulled down, the head face 10 first hits the golf ball so that it does not close and the hook is prevented.

On the other hand, in the case of middle iron, long iron, wood, and a driver, there is a high probability of slice. In this case, as shown in FIG. 8, the shaft fitting portion 23 of the connecting means 20 is assembled to be placed on the front of the head face 10. This is advantageous. (a) shows the clubheads of middle and long irons, and (b) shows the wood and driver clubheads. Golf clubs with long shafts have their heads rotated first and followed by hands during the swing process. The slice is generated because the probability that the face 10 is opened is high. As shown in FIG. 8, when the head face 10 is assembled at the rear of the bottom of the shaft 30, a gentle down blow can be performed during downswing, and the head face 10 may be rotated even when the body is rotated first and the hand is followed. Opening later, the slice is prevented because the probability of hitting the golf ball in parallel with the target direction is increased.
