BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice tool which adjusts the length of a string connected to a ball and eliminates twisting of the string even when the ball is hit.

[0002]

2. Description of the Related Art Conventionally, in a golf practice tool with a cord, a ball and a mat are fixedly attached to both ends of a connecting cord. And the length of the string was about 1 to 2 meters. Further, the connection between the ball and the string is provided by providing a projection that connects the string to the outer shell of the ball.

[0003]

This has the following disadvantages. I. With a string of about 1 to 2 meters whose length could not be adjusted, the flight trajectory of the hit ball could not be confirmed and the practice effect could not be grasped. B. It took time to eliminate the twisting of the string. C. With a string whose length cannot be adjusted, it took time to collect the hit ball. The present invention has been made to solve the above drawbacks.

[0004]

An artificial turf (2) is fitted into a concave portion on the upper surface of a mat (1), and one end of a cloth-coated rubber cord (3) having a length of about 10 meters is attached to the mat (1). And the other end is attached to the polyurethane sponge ball (5). This polyurethane sponge ball (5) is provided with a large through hole at the center portion for passing a string. A through-hole string (10) having a length of sag is passed through the hole and connected in a ring shape. A ring-connecting string (11) is further connected to the through-hole string (10), and about 3 meters from there. With the return joint (4),
A cloth-coated rubber cord (3) is provided through this. The mat (1) has a rubber tee insertion hole (7) on the ball striking direction side, the rubber tee (6) is fitted when used, and two string winding grooves (8) are cut on both outer side surfaces of the string stopper notch (9). Are provided on the outer side in the hitting ball direction.
The present invention is a golf training device having the above configuration.

[0005]

Embodiments of the present invention will be described below. The first embodiment will be described with reference to FIGS. An artificial turf (2) is fitted into a concave portion on the upper surface of a mat (1) having a weight that does not move when hitting a ball. One end of the cloth-covered rubber cord (3) without tying is attached to the outside of the mat (1) in the hitting direction, and the other end is attached to the polyurethane sponge ball (5). After the ball is hit, the polyurethane sponge ball (5) rotates, so that the cloth-coated rubber string (3) connected thereto is twisted. To eliminate this, a return joint (4) is provided between the ball and the string. At this time, as shown in FIG. 4, the return joint (4) is connected in such a manner that one large projection at one end wraps the projection in a loose state with a gap. As a result, one rotation is not transmitted to the other.
To this end, the polyurethane sponge ball (5) was mounted in close proximity to the polyurethane sponge ball (5) so that the rotation of the polyurethane sponge ball (5) was not transmitted to the cloth-coated rubber cord (3). A rubber tee (6) is fitted in the mat (1), and a string stopper notch for fixing the two cloth winding grooves (8) and the cloth-coated rubber string (3) that can adjust the length of the cloth-coated rubber string (3). (9) is provided. When using the present invention, remove the cloth-covered rubber cord (3) from the cord stopper notch (9),
An appropriate length is loosened from the string winding groove (8), and the cloth-coated rubber string (3) is fixed to the string stopper notch (9) again. Polyurethane sponge balls (5) and artificial turf (2)
Put on. At that time, the cloth-covered rubber cord (3) with the return joint (4) is set along the hitting direction from the polyurethane sponge ball (5) by about 30 cm. If you can hit the ball and see the return ball stop near your feet, practice with that golf club. Next, repeat when using a different club. The same is true when teeing up and using a driver. In this case, the polyurethane sponge ball (5) is used as the ball, but in addition, a high hardness rubber sponge ball, a plastic ball,
The same effect can be obtained by using a rubber ball or the like. A second embodiment will be described with reference to FIGS. The features of the second embodiment are as follows. The polyurethane sponge ball (5) is provided with a large through hole in the center portion for passing a string, and the hole opening is chamfered. A string is passed through the hole (10) having a length enough to slacken and is connected in a ring shape. As a result, the rotation in the return direction of the hit ball is not transmitted to the string, and the ball body alone rotates alone. The sagging length prevents kinking of the string in this state. The method of use of the present invention is the same as that of the first embodiment. There is no return joint (4) and instead there is a through string (10). In the present embodiment, the polyurethane sponge ball (5)
The rotation of the ball is separated from the ball by a large hole in the center of the ball and the slack-length penetrating string (10) passed therethrough, the string floats, and the ball rotates through the hole (10). Does not reach. Therefore, only the ball rotates independently. A third embodiment will be described with reference to FIGS. The features of the third embodiment are as follows. The polyurethane sponge ball (5) is provided with a large through hole in the center portion for passing a string, and the hole opening is chamfered. A string is passed through the hole (10) having a length enough to slacken and is connected in a ring shape. Then, a ring connecting string (11) is further connected to the through-hole string (10), and a return joint (4) is attached at about 3 m from there, and a cloth-coated rubber string (3) is provided through this. Have been. As a result, the twisting of the string due to the independent rotation of the return ball, the shift of the rotation center, the lateral rotation, and the like is not completely close. The method of use of the present invention is the same as that of the first embodiment. The one where the return joint (4) was in the immediate vicinity of the polyurethane sponge ball (5) is attached at about 3 meters, and the ring connecting string (11) is connected to the through-hole string (10). . In the present embodiment, when the rotation of the hit ball is twisted due to the rotation in the return direction, the string passing through the hole by the large hole at the center of the ball and the through-hole string (10) having the slack length is changed to the hole. It floats inside and only the ball rotates independently, causing no twisting of the string. The ring connecting string (11) has a through hole (1) when the rotation of the rotating center is shifted at the time of a ground bounce such as the ground when the ball returns after hitting the ball.
In the case of 0), the torsion caused by the offset pulling force is alleviated by the ring connection adapted to the moving center. The return joint (4) blocks the twisting of the string due to the lateral rotation of the flying ball at the time of hitting. A fourth embodiment will be described with reference to FIG. This is provided with two string winding projections (13) as a string winding mechanism and a string spring stopper (14) as a string fastening mechanism. The protrusions include those having an enlarged tip, those having a central portion bent into a concave portion, those which are directed upward and those which are directed forward. It is also possible to attach a string stopper or cut a string stopper into the projection itself on the ball hitting direction side of the two projections.
Other structures are the same as those of the first, second and third embodiments. In the first, second, third and fourth embodiments, there is a combination of a string winding mechanism and a string fastening mechanism. When used, it is the same as in the first, second and third embodiments. A fifth embodiment will be described with reference to FIG. This is a mat (1) having a weight that does not move when hitting without providing a string stopper notch (9) as a string stopper mechanism or a string stopper spring (14), etc., and two string winding grooves (8) Only with this, it is possible to simultaneously perform the string winding mechanism and the string stopping mechanism. Other structures are the same as those of the first, second and third embodiments.

[0006]

According to the present invention, first,
As an effect common to the second and third embodiments, a cloth-coated rubber cord (3) having a length of about 10 meters and having elasticity is provided.
The golf ball (12) can be used to confirm the flight trajectory of the hit ball by using the golf clubs of various counts, thereby improving the golf practice effect.
By providing a string winding mechanism and a string stopping mechanism, the hit ball returning ball can be stopped near the foot, so that it is easy to set when re-hitting the ball. As a difference effect, in the first embodiment, the rotation of the hit ball is prevented from being transmitted to the cloth-coated rubber string by the return joint, so that the twist of the string does not occur immediately. In the second embodiment,
There is no return joint close to the ball, and the use of a string through the hole improves safety and does not cause kinking of the string immediately. In the third embodiment, the kinks of the string due to the continuous hitting are accumulated in the first and second embodiments, but the kinking of the string is completely prevented by providing a return joint between the through-hole string and the ring connecting string. It can be eliminated in a state close to. In these embodiments, the training effect is improved, the hitting ball is easily reset, and the string is not twisted. Therefore, it is easy to practice approach shots in narrow places and driver shots in wide places.The specific gravity of the ball is less than about 1 such as polyurethane sponge ball or high hardness rubber sponge ball. Impact is small and safe. If the ball is made of a heavy and hard ball such as a plastic ball or a rubber ball, the shot feeling becomes close to that of a practical golf ball. By making the string thick and long, it is possible to confirm the hit ball flight trajectory of about 20 meters.
