Abstract

PROBLEM TO BE SOLVED: To provide a swing practice machine for enjoying ball hitting feeling using a pendulum, allowing adjustment of ball hitting sound position in accordance with his/her swing speed, thereby preventing the sound from being emitted too early or too late.SOLUTION: The swing practice machine for enjoying ball hitting feeling is configured so that a pendulum is held by a magnet catcher, the holding force is weakened by centrifugal force of the pendulum during down-swing, and the pendulum collides with an impact plate at the tip end part to generate sound. The position of a long nut attached to the pendulum is changed for adjusting the holding force range with the magnet catcher to generate ball hitting sound at a desired position. The swing practice can be carried out indoor by shortening the overall length, and the ball hitting sound can be changed in some levels by using cushion sheets. When the grip part is changed to a bat grip, the swing practice machine can be used for enjoying batting feeling of baseball.

Description

The present invention belongs to a swing training device that allows a ball hitting sound position to be adjusted in accordance with the swing speed of the user and enjoys a hitting ball feeling.

A conventional swing training device using a pendulum is a swing training device that is mounted on the tip of a golf club shaft and uses a spring-like elastic body. Because the position is different, you can not enjoy the feel of hitting the ball near the impact.

  Patent Publication 2000-288145

In the conventional swing training device described above, there is no training device that can adjust the hitting sound position according to your swing speed, and you cannot enjoy the feel of hitting the ball when the sound is played early or late.

The present invention is intended to solve such a problem, and aims to practice swinging while enjoying the feel of a hit ball.

In order to achieve the above object, the present invention connects a U-shaped shaft with an impact plate to the tip of a short shaft with a grip, and T for fixing a pendulum track to the U-shaped shaft. A pendulum consisting of a shape nut and a long nut that can be adjusted to the position of a bolt with a weight at the tip is attached to the pendulum rotating shaft, and a magnet catcher that catches the pendulum is provided near the pendulum rotating shaft. The holding force range of the magnet catcher can be adjusted by turning the nut, the holding force is cut off by the centrifugal force of the pendulum during downswing, and a sound hits the impact plate. With a swing exerciser that can be adjusted according to the swing speed of the car and can also practice indoors while enjoying the feel of a ball That.

Moreover, if a rubber ring is attached to both sides of the long nut, the long nut is prevented from loosening after the long nut is adjusted.

And when practicing indoors, if the cushion sheet shown in FIG. 5 is attached to the impact surface of the impact plate and practiced, the cushion sheet can change the hitting sound in several stages. This is a swing training device that allows you to practice with less noise and less trouble.

Further, the swing practice device is configured such that several balance plates can be attached to the outer surface of the impact plate so that the weight sense at hand can be adjusted.

Further, in the present invention, when the grip portion is a bat grip, a swing training device for enjoying a baseball batting feeling and a hitting sound is obtained.

As described above, the swing training device of the present invention enjoys a hitting sensation, the hitting sound position can be adjusted according to your swing speed, and since the total length of the training device is shortened, it can be practiced indoors, It will be a practice device that can be practiced anytime and anywhere as long as it is placed in.

And if you are worried about the hitting sound in indoor practice, you can change the hitting sound in several stages if you use it with a cushion sheet, so you can practice without inconvenience.

In addition, since several balance plates can be attached to the external surface of the impact plate, you can adjust the sense of moment at hand and practice swinging to suit you.

In addition, when the grip portion is a bat grip, it becomes a swing training device that allows you to enjoy the feel of baseball batting while enjoying the hitting sound, and is ideal for swing exercises indoors on rainy days.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In the figure, reference numeral 1 denotes a grip, which is attached to a short shaft 2, and a U-shaped shaft connecting long nut 21 is fixed or welded to the tip of the shaft.

The U-shaped shaft 4 is produced by bending a flat bar or plate, and the impact plate 3 is fixed or welded to the tip. A pendulum rotating shaft 8 is fixed or welded to an intermediate portion, and a magnet catcher 9 is fixed or welded in the vicinity thereof.

The short shaft 2 and the U-shaped shaft 4 are connected by screwing a U-shaped shaft connecting bolt 20 fixed or welded to the U-shaped shaft 4 into a U-shaped shaft connecting long nut 21.

In order to fix the pendulum track, the pendulum 7 has a T-shaped nut 5 as a shaft mounting portion, a long nut 6 for holding force adjustment is attached to the middle portion of the bolt attached to the shaft, and a weight is attached to the tip portion. Is attached.

The magnet catcher 9 is constructed by bending the plate 16, sandwiching the magnet 14, fixing it with the magnet fixing bolt 15, and fixing or welding the U-shaped shaft on the top and bottom at a position matching the pendulum track.

By attaching a nut loosening prevention rubber ring 10 to both sides of the long nut 6 for holding force adjustment, the nut can be prevented from loosening and can be adjusted to a desired position.

The impact plate 3 makes a loud sound when directly hit with the pendulum. Therefore, when the trouble is caused by the sound, the cushion sheet 11 having a different thickness is inserted into the cushion seat mounting pin 19 to reduce the sound. Can practice swinging. Therefore, the cushion sheet may be an adhesive cushion sheet for preventing the hitting surface from shifting.

Also, a balance plate mounting long nut 17 is fixed or welded to the inside of the impact plate so that several balance plates 12 can be attached to the outer surface of the impact plate, and the balance plate can be fixed to the balance plate mounting screw 18 there. By doing so, it becomes a swing training device that can adjust the sense of moment at hand.

Further, when the grip portion is the bat grip 13 shown in FIG. 3, a baseball batting feeling and a hitting sound can be enjoyed.
