Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is used to learn accurate shots when practicing golf.

(Prior Art) Most of the conventional golf practice equipment is for correcting the swing or is for practicing even in a narrow space such as indoors.

(Problem that the invention aims to solve) However, most of these tools are aimed at beginners, and those who have already reached a certain level can try to avoid making mistakes while actually hitting the ball at a golf driving range. There are few tools to overcome such problems.
The only way to overcome these problems was to simply hit the ball a lot.

In view of the above points, it is an object of the present invention to provide a training tool that can be used by people who are able to swing at a considerable level to overcome the shortcomings.

(Means for solving the problem) In order to achieve the above purpose, a circle with a diameter of about 13 mm and a bendable material such as paper, cloth or plastic film with adhesive strength on one side and the circle It was formed into a shape in which a circle having a diameter of around 5 mm continues outwardly, and a hole with a diameter of around 5 mm was bored concentrically with the circle with a diameter of around 13 mm.

(Function) With the above configuration, a circle with a diameter of around 5 mm outside the circle with a diameter of around 13 mm will fit into a circular hole with a diameter of around 5 mm drilled inside the circle with a diameter of around 13 mm. By bending it toward the side with adhesive force, both circles with diameters of around 13 mm and around 5 mm are folded in continuous parts, and the sides with adhesive force come into contact with each other and fix it. Therefore, on the non-adhesive side, the adhesive part of a circle with a diameter of around 5 mm outside the circle with a diameter of around 13 mm is exposed to the surface through a circular hole with a diameter of around 5 mm.

Here, the diameter 5 exposed on the non-adhesive side
A part with adhesive force of about 13 mm in diameter is attached to the center of the surface of the ball on the side that will be hit by the golf club, and when the ball is hit in this state, the part with adhesive force in a circle with a diameter of about 13 mm sticks to the club face. At the same time, the adhesive part of the circle with a diameter of about 5 mm that was attached to the ball separates from the ball.

This allows you to know which part of the club face you are hitting the ball with, which is useful for practicing hitting the ball at the sweet spot.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

As shown in Figure 1, this invention forms a circular part 1 with a diameter of around 13 mm and a circular part 2 with a diameter of around 5 mm into a continuous state with a continuous part 4, and inside the circular part 1 with a diameter of around 13 mm, A circular hole 3 about 5 mm in diameter is drilled.

Here, if the length a of the continuous part 4 is made almost the same as the length b from the periphery of the circular part 1 to the hole 3, then the continuous part 4
By bending at the bending part c at the base of the circular part 1, the circular part 2 inevitably fits into the hole 3.

Surface 6 that has adhesive strength when bent at bending part c
If it is bent to the side, the continuous portion 4 and a part of the circular portion 1 will adhere to each other due to the adhesive force of both parts, and the above-mentioned bending will be fixed. In this state, the adhesive portion of the circular portion 2 is exposed from the hole 3 to the non-adhesive surface 7 of the circular portion 1.

As a result, as shown in FIGS. 3 and 4, the adhesive portion of the circular portion 2 exposed from the hole 3 on the non-adhesive surface 7 side is used as the ball on the side to be hit by the club face 9. 5, and when this ball 5 is hit with a golf club 8, the adhesive part of the circular part 1 sticks to the club face 9 at the moment the club face 9 meets the ball 5, After that, at the moment when the ball 5 flies, the area of the adhesive part of the circular part 1 becomes larger than that of the circular part 2.
Since the area of the circular part 2 attached to the ball 5 is larger than the area of the adhesive part of the circular part 2 attached to the ball 5, the adhesive part of the circular part 2 attached to the club face 9 loses the adhesive force of the circular part 1 attached to the club face 9, and the adhesive force of the circular part 2 is larger than that of the adhesive part of the ball 5. He will have to leave.

Therefore, it can be seen that the center of the circular part 1 attached to the club face 9 is the point where the club face 9 and the ball 5 meet.
The state of the golf club swing can be self-analyzed.

When the club is separated from the face 9 after confirming the point of contact, the present invention allows the continuous portion 4 to be bent and inserted through the hole 3 in the circular portion 1 with adhesive force, as shown in FIG. This is because while the adhesive portion of the circular portion 2 is exposed on the non-adhesive surface 7 side, the non-adhesive surface 7 of the continuous portion 4 will appear on the adhesive surface 6 side of the circular portion 1. , this part is not attached to the club face 9 and can be easily removed from this part.

In addition, if the adhesive force of the circular part 1 of the adhesive surface 6 is made stronger than that of the circular part 2 (if the adhesive force of the circular part 2 is made weaker than that of the circular part 1), the club face 9 can be more secure.

In addition, as an example, the shape of the continuous portion 4 is approximately trapezoidal as shown in the drawing, but the shape is not critical as long as the circular portions 1 and 2 can be made continuous, and the entire shape is as shown in FIG. A similar effect can be obtained when the adhesive is molded into a shape or a similar shape, and the areas or adhesive strengths of the adhesive parts on both sides are made different.

(Effects) As described above, the present invention allows you to clearly know which part of the club face is hitting the ball by checking the position of the adhesive on the club face after the shot. This is effective for overcoming misshots such as gear action that occur when the club face is hit off the sweet spot.
