Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing analysis apparatus for a golf club, which records and reproduces the movement of the golf club and the posture of the player when the golf club is swung.

[0002]

2. Description of the Related Art Golf is said to be a swing form sport for golf clubs. It is said that the results are good if the form is correct. However, the result cannot be known until the golf ball is hit with the correct form, for example, so-called slice or hook ball, at least in the driver or long iron and after flying 120 yards or more. However, the practice of golf is usually practiced in an extremely narrow place, and the player cannot judge whether the ball has been hit in the right direction, in other words, whether the ball has the right form.

Therefore, it is possible to record the player's form on a video. However, the conventional golf swing analysis device with a video camera interlocked with it cannot be rewound or played on the spot, and when it is desired to play it, it is necessary to go to a place with a recording device and operate it. For this reason, it was impossible to practice and check the golf swing each time to correct it repeatedly.

[0004]

Therefore, it is most effective to practice golf while checking the swing each time the practice is performed and correcting the swing so that it is correct. On the other hand, each time, it is required that the image be easily viewed by the player himself.

That is, the present invention detects the start of the address by a sensor arranged near the set part of the golf ball without using mechanical means, operates the video camera to record the signal, and after the end of the swing hit It is rewound automatically and can be immediately reproduced on the display.

[0006]

The structure of the present invention is characterized in that a mat (1) installed in front of a player and a set position of a golf ball provided substantially in the center of the mat (1). (2), a large number of sensor groups (3) provided in the left-right and front-rear directions of the set position (2), and a sensor group (1) installed on the side or rear of the mat (1) facing the mat (1) direction. To a plurality of video cameras (4) and a recording device body (5) linked with the video cameras (4), and after the golf swing of the player is completed, the video camera (4) and the recording device are connected to each other. It is provided with a mechanism for stopping the operation, rewinding the tape automatically imaged by the recording apparatus main body (5), and reproducing it on the disc play.

Thus, the player hits the golf ball placed at the set position (2) on the mat (1) with an appropriate golf club. In this case, a large number of sensor groups provided behind the player. By (3), it is detected whether or not the club head is directed in the hitting direction at the correct incident angle, in other words, whether the player's golf club swings up to the inside or outside, and at the same time, the video camera ( 4) is driven to record the form, and at the same time, the form is recorded in synchronization with the sensing signal from the sensor group (3) behind the player.

Next, it is determined whether or not the ball is hit at a contact position between the golf head and the ball caused by the player's swing, that is, at a correct position that does not cause so-called top or double when hitting the ball, and the ball after hit is correct. The emitting direction, that is, whether or not the ball is a so-called slice ball or hook ball is detected by the sensor groups (3) provided in the respective directions similarly to the above, and recorded at the same time as video recording.

After the player's swing is completed, the player can reproduce the tape by swinging the tape, and whether or not the swing form of the club at that time is from the correct incident direction to the correct exit direction, and whether the swing form of the ball and the club head is correct. It is determined whether or not the contact position is correct, and the result is displayed at the same time.

By providing a plurality of video cameras (4) on the side of the mat (1) and behind the mat (1), two screens of the form can be recorded from the front and side of the player. It is also a feature that it can be displayed on the same display at the time of playback, in which case the player can capture his own form not only from the front but also from the side at the same time and see the information for form correction at the same time. Can be done.

Further, by adding a light beam for narrowing the light receiving angle to the above-mentioned sensor group (3), so-called noise given to the sensor group (3) is removed, and information on only the golf club operation is sent to the sensor group (3). It is also a feature that it is given, and the set position (2) of the golf ball is changed according to the selection of a golf club such as a so-called wood club, long iron, middle iron, short iron, etc. One of the features is that the player knows whether or not the correct position is addressed with respect to the ball set position (2).

Further, in the present invention, it is important to inform the timing of the address of the player constituted by each sensor group (3) to the recorder main body (5) so that all the mechanisms start to operate. As a result, there is no waste of tape feeding, and the analyzer can be effectively used repeatedly, so that waste of time is reduced.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. (1) is a mat on a rectangular flat plate made of a material such as synthetic rubber, and is placed on the ground so that the front of the player is in the longitudinal direction as seen in FIG.

As shown in FIG. 3, (2) is a ball set position provided on the rear side of the longitudinal center axis (A) on the mat (1). In FIG. 2, since the player has a driver, It is near the toe of the player.

(3) is a group of a plurality of sensors, which is behind the set position (2) of the ball, that is, when the player swings the golf club, the axis (A) of the head's incident direction.
A plurality of sensor groups (3) provided at a predetermined interval from the set position (2) and provided in the direction perpendicular to the axis (A).
a), one sensor (3b) immediately after the ball set position (2) in the direction of incidence of the club head, and immediately before the exit direction after the club head has passed the ball set position (2). And a plurality of sensors (3c) (3d) arranged in a direction perpendicular to the axis (A), and this sensor (3
c) (3d) is a plurality of sensors (3f) (3g) arranged at parallel positions at relatively long intervals.

Further, (4) is a television camera, and two units are installed in front of and behind the mat (1) as seen from the player, and (5) is a recorder main body placed at an appropriate position visible to the player. The main body (5) is the TV camera (4)
The video signal and the optical signal from each sensor group (3) are received, the video output and the information from the sensor group (3) are converted into character information, and at the same time, the display (6) of the recorder main body (5). It can be displayed above. In this case, the two TV cameras (4) transmit video information of the front and side of the player to the recorder main body (5), respectively, and as a result, each of the two video cameras is displayed on the display (6) of the main body (5). The screen is supposed to be displayed.

There are various conceivable configurations of the recording apparatus main body (5), but FIG. 4 shows an example thereof. Various circuit configurations of the sensor group (3) are possible, but FIG. 5 shows one example. The description of the circuit configurations of the recording apparatus body (5) and the sensor group (3) will be given together with the operation shown in FIGS. 6 and 7.

Thus, the player who practices the practice places the golf ball on the ball set position (2) on the mat (1). At the same time, the sensor group (3) senses the start of the address by the player, and thereby the video camera (4) of FIG.
Send a signal to. As a result, the video camera (4) enters the image capturing state, and at the same time, the recorder main body (5) starts to operate. Here the player's club swing is a video camera (4)
Thus, the image is recorded from two different locations, and the recording apparatus main body (5) records the image with the screen divided into two.

On the other hand, at the same time, when the golf head of the player is hit down and the head comes to the rear of the golf ball set position (2), first of all, the rear sensor group (3
a) works to detect whether the club head came in, outside, or at the right angle of incidence,
This is captured as a signal and sent to the recorder main body (5) for information processing by the main body (5) for docking with the video information of the video camera (4) and recording as character information and the like.

Similarly, along with the progress of the swing of the golf club, the position (height) at which the club head hits the ball and the height of the club head are sensed by the sensor (3b) provided immediately after the position (2) at which the golf ball is set. The sensor (3c) (3d) immediately before the set position (2) and the set position (2)
And a sensor (3f) (3g) provided at regular intervals
Sense the ejection direction of the golf head after passing through the set position (2).

That is, if it is assumed that the club head is ejected from the sensor (3c) in the direction of the sensor (3f), the slice ball may be provided, or the sensor (3d).
Therefore, if it is assumed that the player is missing in the direction of the sensor (3g), it is possible to inform the player that the hook ball has come out and that the correct swing is not performed, if provisionally ordered.

In FIG. 3, a plurality of sensors (3) are provided along the axis (A) immediately before the ball setting position (2).
e) was arranged. This is because when the club head passes over the sensor (3e) [when the sensor (3e) senses that the club head has passed], the recording device body (5) processes the information that the ball has been hit with the correct form. This is because it can be displayed on the display (6).

When the swing of the club is finished, the recorder main body (5) is stopped. In this case, the player may perform the stop operation, but in many cases, the recording device (5) detects that the club head has passed the last sensor (3f) (3g) on the mat (1). It is preferable to automatically send it to the above). Then, the screen is automatically rewound by one swing, and two screens can be reproduced on one display. This gives the player 1
Images taken from two different positions after one golf swing can be viewed as video information on one display (6) and information by signals from each sensor group (3) as text information. You will be able to correct it in the next exercise because you will recognize your form and find out what is incorrect.

Further, the golf swing analyzing apparatus according to this embodiment records and reproduces one after another by a signal continuously generated while the tape filled in the recorder main body (5) has an unrecorded portion. You can check and correct the form, and after practice, you can take this tape home and take a closer look at it.

In this case, it is preferable to use together with a golf club analysis device for displaying the trajectory of the ball and the trajectory of the club. By doing so, it is possible to know the speed of the form and the ball, the distance traveled, the direction, etc. at the same time.

Further, it is preferable to attach an attached optical system such as a transparent glass rod-shaped relay lens to the optical sensor for detecting the address by the golf club and for detecting other signals. This is because the signal can be detected only from the shadow generated by the illumination light for signal generation installed at the upper part of the practice field, and it is possible to have a structure that is not affected by changes in ambient light. Is.

Generally, golf clubs include wood and iron. In the case of normal wood, the ball is teeed up. In this case, the set position (2) is set to be in front of the player's toe, whereas in the case of a long iron, it is slightly forward from the center position with respect to the player, in the case of a middle iron, it is in the center, and in the case of a short iron, it is behind. Position.

Therefore, in carrying out the present invention, the apparatus body (5) is provided with an operating mechanism for correcting the aiming position of each of the cameras (4), and the switch (S) of the mechanism is operated. Therefore, it is desirable to devise so that a correct image can be taken at any golf ball set position (2).

Thus, in this embodiment, since the image pickup is started by the signal generated by the address and the rewinding is automatically performed after the recording, it is possible to reproduce and watch the golf swing after the end of the swing without changing the stance. As a result, the swing form can be easily confirmed and corrected, and further, if there is an unrecorded portion on the tape of the recording device body (5), the golf swing analysis can be continued.
