Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a head up corrector used when a golf player makes a shot to correct the head up at the moment of impact.

[Summary of the idea]

The head up corrector according to the present invention is arranged near the hitting point of a golf ball, detects the impact of the golf ball, and lights up a lamp after a predetermined time delay from the detection time.
At the time of shooting, the player is able to recognize the presence or absence of a head up by identifying whether the lamp is lit, and the player can correct the head up by himself/herself.

[Background of the idea]

When making a shot in golf, a player needs to keep his eyes on the golf ball for a short period of time from the moment it makes an impact. If you turn your head in the direction the ball will fly from the moment of impact (head up), the axis of your swing will shift, resulting in a poor hit rate with the club head or the inability to fly the ball in a predetermined direction. Therefore, players who have this habit need to correct it, but there is a problem in that it is difficult for the player himself to recognize the shot because it ends in an instant.

[Purpose of invention]

It is an object of the present invention to provide a head up corrector that can correct such head up caused by players and practice to make a correct swing.

[Structure and effect of the idea]

The present invention is a head up corrector for correcting head up during shots in golf, and includes a microphone that collects the impact sound at the time of impact.
a delay circuit that delays a detection signal from a microphone for a predetermined period of time; a monostable multivibrator that operates for a certain period of time when an output is given from the delay circuit; and an indicator lamp that is driven by the output of the monostable multivibrator. It is characterized by comprising the following.

According to the present invention having such characteristics, after a minute period of time determined by the post-impact delay circuit has elapsed, the lamp of the head up straightener placed near the dot is activated for a predetermined period of time determined by the monostable multivibrator. I'm trying to turn it on. If the player can see the light from the lamp, he or she can recognize that there was no head up and that the correct shot was made. Also, if you cannot see the light from this lamp, a head drop will occur after the shot, indicating that you were not paying enough attention to the ball. Therefore, by practicing shots to be able to recognize the light from this lamp, it will be possible to correct the player's head drop. Also, since the impact sound is detected using a microphone, it is possible to detect not only the teeing ground but also the second shot,
It can also be used at the shot position for the third shot.
It becomes possible to correct head sagging.

[Explanation of Examples]

FIG. 1 is a block diagram showing an embodiment of a head up corrector according to the present invention. The head up straightener 1 according to the present invention is placed on the ground in the immediate vicinity of the ball to be shot. The head up straightener has two microphones that detect the sound at the moment of impact.
The output of the microphone 2 is given to an amplifier 3 as shown in FIG. The amplifier 3 amplifies the output of the microphone 2 to a predetermined level, and the output is given to the delay circuit 5 via the rectifier circuit 4. The delay circuit 5 delays the shot signal given by the rectifier circuit 4 for a predetermined period of time, and supplies its output to the monostable multivibrator 6. The monostable multivibrator 6 is triggered based on the output of the delay circuit 5 and generates an output for a predetermined period of time. The output of this monostable multivibrator 6 is given to a lamp 7.

Figure 2 shows a head lift straightener 1 according to this embodiment.
FIG. 2 is a perspective view showing a state in which the head up corrector 1 is used, and shows a state in which a player is shooting a ball with the head up corrector 1 placed near the ball hitting position. In this figure, a golf ball 9 is fixed on a tip 8. Here, it is preferable that the microphone 2 of the head up corrector 1 be installed on the ball side in order to obtain an impact sound signal at the time of impact, and the lamp 7 should be installed at the top of the corrector so that it can be confirmed by the player. be. Now, when the player shoots the golf ball 9, an impact sound is transmitted from the microphone 2 at the moment of impact as shown in FIG. 3a. This impact sound signal is amplified to a predetermined level by an amplifier 3, rectified by a rectifier circuit 4, and provided to a delay circuit 5. Then, as shown in FIGS. 3c and 3d, the signal is delayed for a predetermined time by the delay circuit 5, and based on the falling signal, the monostable multivibrator 6 is triggered and the lamp 7 is turned on. This lighting time can be arbitrarily changed by setting the operating time of the monostable multivibrator 6.

With such a configuration, the lamp 7 is turned on after a short period of time has passed after the impact. Therefore, if the player can see the light from the lamp 7, he or she can recognize that the shot has been completed without raising the head. However, if the player cannot see the light from the lamp 7 after the impact, it means that the ball's head has gone up and he did not check the position of the ball immediately after the impact, and he will be able to recognize his own head up.
