Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention generally relates to a grip,
The present invention relates to a golf club having a shaft and a head, and more particularly, to a golf club head having an improved hitting plate and a weight for stabilizing its swing.

2. Description of the Related Art Various golf clubs, such as wood, irons and putters, are used depending on a target distance for sending a ball. When playing a golf game, one of the most important things that will definitely help in winning the game is to hit the first shot and send the ball as close as possible to the intended target. Therefore, many attempts have been made to provide golf club heads having improved flight distance between shots and balls by providing various materials and structures to the heads. For example, using metal for a wood club, or indenting the rear surface of a head. However, such conventional attempts have
Primarily directed solely at improving the ball's flight distance or increasing the head's striking surface, it has made little contribution to training young golfers. That is, conventional golf clubs rely solely on the golfer's sensation to control slices or hooks, and it is very difficult for an inexperienced golfer to control the sensation of a ball or a shot. The Korean patent No. assigned to the present applicant. 99-0215992
Discloses a golf club head having a front hitting surface and a rear surface formed integrally with a club head body in order to improve the flight distance and hit feeling of the ball. The head is engraved on the back to form multiple concentric steps,
This absorbs the impact of the ball hitting the ball,
Therefore, the restoring force is characterized in that the flight distance of the ball can be increased. That is, when hitting the ball, the club head is elastically bent backwards with the help of concentric steps engraved on the rear surface, thus absorbing the vibrations and shocks imparted to the head and then restoring its force Thereby, the flight distance of the ball can be improved.
Accordingly, the golfer's feel at impact is also improved. However, with this structure, there is a center of gravity near the heel, which results in an immature golfer having an open swing, as with a conventional golf club, and therefore, is unlikely to hit correctly In some cases, it becomes impossible and unexpected slices occur. In addition, it is not easy to properly engrave the rear surface of the club head to form concentric steps. Furthermore, since the center of gravity is behind the head, an inexperienced golfer has little control over its position, especially when performing a long shot. Therefore, inexperienced golfers require a great deal of training to control a golf club.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved golf club head having means for improving both the ball's flight distance and feel at impact. It is another object of the present invention to provide an improved golf club head having a means by which an unskilled golfer can easily feel a shot. Yet another object of the present invention is to shift the center of gravity of the club head body from the heel to the toe to improve the moment of inertia of the head, thus significantly increasing the distance traveled by the ball, and to provide an unskilled golfer. SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved golf club head having a means for correctly shooting without falling into an open swing.

According to one aspect of the present invention, a golf club head is a club head body having a hosel for receiving a golf club shaft, a heel and a toe, wherein the club head body comprises an attachment. A club head body that is hollow toward the rear to form the opening, a weight protrusion projecting from a part of the attachment opening near the toe to optimize the center of gravity of the club head body, and an attachment. A separate hitting plate tightly fitted in the opening, a shock absorbing plate consisting of a plurality of concentric steps engraved on the back of the hitting plate, and a hitting ball that grasps the weight projection when the hitting plate is fitted in the attachment opening A connection opening formed in the plate, whereby the hitting plate elastically absorbs the impact of a golf ball collision,
In addition, the center of gravity is shifted from the heel to the toe by the weight projecting portion.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail, by way of example, with reference to the accompanying drawings, in which: 1 and 2
Referring to (B), the golf club head includes a hosel 13 for receiving a golf club shaft 200, and a club head body 10 having a heel and a toe. The club head body 10 has an attachment opening 11.
Is formed hollow toward the rear.
In order to optimize the center of gravity of the club head body 10, a weight protruding portion 12 protrudes from a part of the attachment opening 11 near the toe. A separate hitting plate is tightly fitted in the attachment opening 11. The shock absorbing plate 30 includes a plurality of concentric steps 31 engraved on the rear surface of the hitting plate 20. A connection opening 21 is formed in the hitting plate 20, and when the hitting plate is fitted into the attachment opening 11,
The weight projection 12 is grasped. As shown in FIGS. 3 and 4B, the shock absorbing portion 30 ′ may include a plurality of concentric elliptical grooves 32 formed on the rear surface of the hitting plate 20. Reference number 100 represents a golf ball. As shown in the drawing, since the ball hitting plate 20 is formed separately from the club head main body 10, it is easy to engrave the rear surface and correctly form the concentric step 31. The diameter of the step 31 of the concentric circle gradually increases upward, and therefore, the shock absorbing portion 30 colliding with the golf ball 100 firstly
The elastic force that is resiliently bent inward into the attachment opening 11 and then restores increases the thrust of the golf ball 100 applied by the golfer's swing, thus significantly increasing the ball's flight distance. The weight projecting portion 12 protruding near the toe and being tightly fitted in the connection opening 21 of the hitting plate 20 shifts the center of gravity of the club head body 10 near the toe and increases the moment of inertia of the head, and therefore, The flying speed of the ball is effectively increased by increasing the swing speed of the head.
In addition, this structure helps to effectively prevent both open swing side spinning which results in the club head body 10 pivoting forward and backward relative to the slice and golfer's body. In contrast, the structure of the conventional golf club head body 10 has a center of gravity near the heel, so that an inexperienced golfer performs an open swing, and therefore, an inexperienced golfer generally performs accurate shots. Cannot be performed, and unexpected slices may occur. further,
Since the center of gravity is behind the head, an inexperienced golfer can hardly control the position, especially when performing a long shot. Therefore, an inexperienced golfer requires great training to control a golf club. Referring to another embodiment of FIGS. 3 and 4 (B), the shock absorbing portion 30 'is replaced by a plurality of concentric ellipses formed on the rear surface of the hitting plate 20' instead of the concentric steps of the previous embodiment. It consists of a groove 32. Similarly, the shock absorbing portion 30 ′
It is elastically bent backwards to absorb the impact of the impact of the golf ball 100, thus reducing the impact applied to the golfer's body, and then its restoring elasticity,
Increase the flight distance of the ball. This also absorbs the vibration caused by the impact of the golf ball 100 and stabilizes the intended flight distance of the ball. In addition, this is
The stress applied to the hitting plate 20 'is effectively dispersed, so that even an unskilled golfer can easily feel a hitting ball through the damped vibration transmitted from the head to the grip. Further, the simple structure of the shock absorbing portion 30 'shown in the previous embodiment can be easily obtained by simple engraving as compared with the shock absorbing portion 30 of the previous embodiment. It goes without saying that the shape of the groove 32 can take various shapes other than an elliptical shape such as a circular shape.

As described above, the shock absorbing parts 30, 3
With an advanced configuration combining 0 'and the weight protruding portion 12, even an inexperienced golfer can stably perform a long shot and easily obtain the feel of a shot. Although the present invention has been described in conjunction with the specific embodiments illustrated in the accompanying drawings, those skilled in the art may make various changes and modifications to the invention without departing from the spirit of the invention. The gain is easy to understand.
