The present invention relates to a golf club (Golf Club), in particular, by telling the golfer through the melody whether or not the golf ball on the impact surface of the head during the swing of the golf club (Impact), to maintain the golfer's accurate swing posture Of course, it relates to a golf club to attach a soft member to the hitting surface of the head to minimize the repulsive force when hitting the golf ball and to adjust the direction and distance of the hitting to learn the sense of hitting.

In general, a golf club is composed of a head (Head), shaft (Shaft), and grip, and is divided into wood (wood), iron (iron), putter (Putter) according to the shape and purpose of use, these Each is divided into several types according to the location, distance and angle to hit each.

Figure 1 schematically shows a conventional putter structure of such a golf club.

As shown in FIG. 1, the putter 50 has a rubber grip 51, which is a grip part of a golfer, a shaft 52 forming a body at a lower end of the grip 51, and the shaft 52. A) 'b' shaped head having a hitting surface (53a) hitting the golf ball at the bottom.

The putter is a golf club mainly used to accurately roll the golf ball on the green and put it into the hole cup, unlike wood and iron used for the purpose of striking the golf ball on the field to blow away. Sophistication and skill are required to read correctly and adjust the putting strength.

Therefore, it is important for the golfer to learn the correct grip position and the correct swing posture from the beginning of the golf course, since the golf ball can be attacked only by maintaining the correct swing posture during the putting.

However, in the case of a beginner golfer, the head up occurs frequently before the impact is over in the golf swing, and there is a problem that the swing posture cannot be maintained accurately. This may cause a bad directionality of the hitting and swinging in extreme cases, but in the past, novice golfers did not have a device for preventing such head-ups themselves.

Moreover, since the conventional putter head is made of a metal material, there is a drawback of not only absorbing power to the golf ball at the time of putting, but also a very high repulsive force. Accordingly, unless the swing force and swing angle are properly adjusted during the putting, it is very difficult to accurately adjust the direction and distance to the hole cup. In particular, this problem, the larger the beginner golfer, the lower the accuracy of the putt and putter cause.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention, by informing the golfer through the melody whether the golf ball on the impact surface of the head during the swing of the golf club accurately, In addition to maintaining the golfer's accurate swing posture, a soft member is attached to the hitting surface of the head to minimize the repulsive force when hitting the golf ball and to adjust the direction and distance of the putter so that the golfer can learn the sense of putting. In providing a club.

In order to achieve the above object, the present invention is a grip of the golfer on the top of the grip, the shaft is connected to the grip to form a body, the head having a hitting surface coupled to the bottom of the shaft hitting the golf ball, and In a golf club comprising a groove formed in the center of the hitting surface of the head and a flexible cover detachably inserted into the groove and absorbing the golf ball, a groove is formed in the center portion of the groove, An IC (Integrated) includes a contact switch that contacts or shorts a contact according to the hit, a speaker that outputs a melody according to the contact state of the contact switch, and a battery for supplying power so that a melody occurs when the golf ball is hit. Circuit) characterized in that the substrate is arranged.

The golf club putter 10 according to the present invention, as shown in Figure 2, the grip portion 11 of the golfer, the shaft 12 connected to the lower end of the grip 11, and the shaft 12 It is coupled to the bottom of the) is composed of a head 13 having a hitting surface of the golf ball.

Since the head of the putter according to the prior art is made of a metal material, the repulsive force on the golf ball is relatively large, and it is difficult to adjust the direction and distance of the hitting.

In order to solve this problem, the present invention, as specifically shown in Figures 3 and 4, 'b' having a hitting surface coupled to the bottom of the shaft 12 of the putter 10 hitting the golf ball on one surface In the magnetic head (13), a rectangular groove (14) is formed in the center of the hitting surface, and a separate soft cover (Cover, 15) is detachably inserted into the groove (14). Doing.

In particular, the flexible cover 15 is formed by injection molding with rubber or synthetic resin to have absorption and cushioning properties in contact with the golf ball and to minimize repulsive force against the golf ball.

According to this structure, the hitting surface that the golf ball is in contact with the putt absorbs the putting force to minimize the repulsion force on the golf ball, the golfer can easily adjust the desired putting direction and putting distance. Accordingly, the accuracy of putting and swing can be improved, and the putting success rate can be greatly increased.

Further, between the groove 14 and the flexible cover 15, as shown in Figures 3 to 6, the contact switch 21 and the contact switch 21, so that the melody occurs when the golf ball is hit. The IC board 20 is provided with a speaker 22 for outputting the melody memorized in an IC (Integrated Circuit) element and a battery 23 for supplying power.

In the present invention, at least one of the flexible cover 15 or the recess 14 of the head 13, as shown in Figure 3 (b), so that the melody is largely generated to the outside. A plurality of through holes 15a and 15b may be formed. That is, as can be seen from FIG. 3 (b), a plurality of through holes 15a are formed in left and right portions of the flexible cover 15, or grooves 14 corresponding to the left and right sides of the flexible cover 15 are formed. It is possible to form a plurality of through holes 15b in the left and right portions of the). The plurality of through holes 15b penetrate from the groove 14 to the surface opposite to the striking surface of the head 13.

The IC substrate 20 may be provided in a groove 16 formed in the center portion of the groove 14 so that the IC substrate 20 is disposed without flow between the groove 14 and the flexible cover 15.

Here, the upper surface of the contact switch 21 of the IC substrate 20 is in contact with the inner surface of the flexible cover 15.

In order to achieve miniaturization and thinning, the IC substrate 20 preferably uses a piezoelectric speaker as the speaker 22 and an ultra-thin lithium battery as the battery 23.

The contact switch 21 is a switch for contacting or shorting the contact according to the strike to select the output of the melody from the IC element stored in the IC substrate. In addition, the speaker 22 converts an electrical signal into a voice signal and outputs a melody to the outside, and the battery 23 supplies power for storing and outputting the melody.

The output of the melody is determined by the golfer's swing position, that is, by the hitting portion of the hitting surface of the putter head 13.

According to this melody structure, when golfers put golf balls on the green, they can develop the habit of fixing the golf ball with the stare straightly without causing head-up before impact or after impact. It can help you learn.

That is, when the golfer puts the golf ball in a state where the golfer stares straight at the golf ball without heading up, the golf ball is accurately impacted at the center portion of the flexible cover 15 which is the hitting surface of the putter head 13. As shown in FIG. 5, the inner surface of the flexible cover 15 is momentarily pressed on the upper surface of the contact switch 21 of the IC substrate 20, which is in contact with the inner surface by an elastic force, and the contact switch 21. ) Will be turned on. At this time, the melody memorized from the IC element of the IC substrate 20 is output from the speaker to the outside through a through hole (15a) formed in the flexible cover for a predetermined time, the swing posture and the impact site is made correctly to the golfer You will be notified. Thereafter, the inner surface of the flexible cover 15 is released from the contact with the contact switch 21 while returning to an initial state by a restoring force, thereby terminating the output of the melody. As described above, when the golf ball is precisely impacted on the hitting surface of the putter head by the correct swing posture, the golf ball can be sent exactly to the desired position of the golfer, thereby improving the success rate of the putting.

On the other hand, when putting the golf ball, if the impact area of the golf ball on the hitting surface of the putter head 13 is not accurate, the inner surface of the flexible cover 15, which is the hitting surface, can press the contact switch inwards. Since no elastic force is generated, no melody occurs. Therefore, the golfer will know that his swing position and putting have not been made correctly.

As described above, according to the present invention, by attaching a soft member to the hitting surface portion of the head, by minimizing the repulsive force on the golf ball when hitting, the golfer can easily adjust the desired hitting direction and distance, You can improve the accuracy of your swing.

In addition, according to the present invention, by embedding a melody element inside the head so that the melody is generated when the hitting, to develop a habit of staring at the ball until there is a melody occurs after the hitting, it becomes distracted by the head up Since the swing posture can be corrected, it can help to improve the swing accuracy.

Although the present invention has been described with respect to the preferred embodiment, the present invention is not limited thereto, and various modifications and applications will be possible to those skilled in the art without departing from the gist of the present invention.
