[Industrial applications]

 The present invention relates to a golf swing check device used for checking or correcting a golf swing.

[0002]

[Prior art]

 The basics of golf swing are to make a rotational movement around an appropriate swing axis, and in order to fly the ball in a desired direction, especially in a straight line direction, it is said that a rotational movement around the swing axis is a condition. ing. Therefore, improving golf is first about creating an image of rotational motion centered on the swing axis.

[0003]

[Problems to be solved by the device]

 By the way, it is said that it is not easy to imagine the swing axis, and even advanced users are said to have difficulty. It is said that it takes a long time to acquire the image of the swing axis, such as repeating the shadow swing and hitting a large number of balls. Conventionally, a mirror or a video tape recorder was used as the acquisition method. Therefore, methods such as visually confirming the swing have been taken. Even with this method, there is a visual gap and a time gap between the actual swing and its confirmation, so it is difficult to accurately grasp the swing axis, and it is difficult for the trainer without a trainer to grasp it. Had the drawback of being selfish and prone to habits.

In addition, when the swing shaft swings, unnecessary force is applied to the waist and shoulders, causing a feeling of fatigue and further inconvenience such as adversely affecting the body cannot be ignored.

Therefore, the present invention makes it possible to easily check whether or not proper swinging is being performed, and to easily obtain proper swinging around the swing axis in a short time in a simple golf course. It is intended to provide a swing check device.

[0006]

[Means for Solving the Problems]

 The golf swing check device of the present invention comprises a light source (light emitting diode 8) which emits a spot light (6), a light transmitting portion (4) which incorporates the light source and transmits the spot light from the light source. An outer case (2) provided and an angle adjusting means (a seating section 30 and a hinge mechanism 31) which is provided in the outer case and guides the spot light from the light transmitting section to the line of sight of the trainee (38). It is characterized by having.

In the golf swing check device of the present invention, a reflecting mirror (18) is installed inside the outer case to reflect the spot light from the light source and guide the spot light to the light transmitting part. Is characterized by.

[0008]

[Action]

 The golf swing check device of the present invention utilizes the interlocking relationship between the line of sight and the body movement, and when swinging the golf ball with the line of sight fixed, swing shaft swing can be suppressed, which is an ideal golf swing. It is based on the knowledge and the rule of thumb that it can be done.

That is, the spot light emitted from the light source enters the line of sight of the practitioner through the light transmitting portion formed on the outer case. The practitioner should stand in a position corresponding to the ball to be hit so that the spotlight can be caught in the line of sight in an ideal posture. Then, while confirming the spot light within the line of sight, the club rotates. In this case, the practitioner keeps both the ball and the spot light in sight, and swings the club swing naturally from the backswing. Such a swing with a fixed line of sight moves away from the rotational movement that the practitioner is aware of, and approaches an ideal rotational movement based on golf theory. Then, when such practice is performed, the center of rotation can be recognized from the rotational movement, which leads to the acquisition of the swing axis. After recognizing the swing axis, check the movement of the spot light centering on the swing axis, and you can do the swing without force in the absence of such movement, and you can easily and ideally make a golf swing in a short time. You will be able to get it.

Particularly, unlike the practice using a conventional mirror or a video tape recorder, the practitioner only has to fix the line of sight to the spotlight and swing. Moreover, fixation of the line of sight has the advantage that it promotes mental concentration and allows proper training.

In such a golf swing check, the beginner can sense the swing axis in a short time without needing a coach, and an advanced player can visually check the swing axis swing state. It can be easily confirmed and the swing can be corrected.

Further, in the golf swing check device according to the second aspect of the invention, since the reflecting mirror is installed, the optical path length can be lengthened in the outer case, and the spot light can be effectively guided into the trainee's line of sight. it can.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

1A, 1B and 2 show an embodiment of the golf swing check device of the present invention. This golf swing check device uses an outer case 2 formed of a metal plate, a synthetic resin plate, or the like in the shape of a rectangular tube, and one side surface of the outer case 2 has a translucent light for guiding light to the outside. The part 4 is formed.

Inside the outer case 2, a light emitting diode 8 is installed as a light source that emits the spot light 6, and the light emitting diode 8 is mounted on a printed circuit board 10 firmly fixed to the flat surface portion of the outer case 2. is set up. Since the position and the direction of the light emitting diode 8 affect the accuracy of the irradiation direction of the spot light 6, the light emitting diode 8 is firmly fixed in the desired direction and position. A lighting circuit 12 for the light emitting diode 8 is mounted on the printed circuit board 10, and a power source 14 including a battery or the like is installed adjacent to the printed circuit board 10. A switch 16 such as a push button switch for operating the lighting circuit 12 is installed on the ceiling of the outer case 2, and a touch button portion 17 is formed on the outer surface of the outer case 2. .

The upper surface of the printed circuit board 10 is set to the optical path of the spot light 6, and the spot light 6 passing through the upper surface of the printed circuit board 10 reaches the reflecting mirror 18. The reflecting mirror 18 is installed on the back side of the exterior case 2 and is fixed at an angle necessary to guide the spot light 6 to the light transmitting portion 4 of the exterior case 2. By disposing such a reflecting mirror 18, the optical path length of the spot light 6 can be set to about twice the length of the outer case 2, and the length of the outer case 2 can be shortened accordingly. We are contributing to the miniaturization of the outer case 2. If the outer case 2 is set large and the optical path is sufficiently long, the reflecting mirror 18 is not necessary.

A transparent plate 20 that selectively transmits the spot light 6 is installed on the transparent portion 4 side. The translucent plate 20 is installed so that it can be replaced by removing it in a groove 24 formed in the outer case 2. A seating portion 30 is attached to the bottom surface of the outer case 2 as an angle setting means for guiding the spot light 6 that has passed through the transparent plate 20 in a desired height direction via a hinge mechanism 31. . The hinge mechanism 31 is provided with some kind of stop mechanism for bending the support shaft 33 in order to fix the seating portion 30 at a desired angle θ.

As shown in FIG. 3, the light-transmitting plate 20 is provided with a light-shielding portion 30 together with a circular light-transmitting portion 28 that represents the movement allowable range of the spot light 6. The translucent plate 20 is formed of a transparent material plate such as an acrylic plate or a glass plate, and the light shielding portion 30 is formed by, for example, applying a light shielding coating on it. That is, the shape of the translucent portion 28 of the translucent plate 20 has a function as a sight, and is set to intervene between the light source and the vision of the practitioner to catch the movement of the spot light 6 on the line of sight. Of.

Next, FIG. 4 shows an embodiment of the lighting circuit 12. In this lighting circuit 12, after the switch 16 is closed, the light emitting diode 8 is lit only for a fixed time T. That is, to the power supply 14, the resistor 32 is connected to the anode side and the light emitting diode 8 is connected to the cathode side of the power supply 14 via the timer circuit 34. The setting input is applied to the control input side of the timer circuit 34 from the intermediate connection point of the series circuit of the resistor 36 and the switch 16 connected to the power supply 14.

Next, FIG. 5 shows a specific circuit configuration example of the lighting circuit 12, and the timer circuit 34 in the lighting circuit 12 is composed of an IC. A 2-input NAND circuit 341 is installed on the input side of the timer circuit 34. A voltage input is applied to one input side of the NAND circuit 341 from the connection point of the resistor 36 and the switch 16, and the other side. The output of the NAND circuit 342 on the output side is fed back to the input side of. The output side of the NAND circuit 341 is connected to one input side of a 2-input NAND circuit 342 via a capacitor 343 and a resistor 344 which form a series circuit. Further, a resistor 346 is connected between the connection point of the capacitor 343 and the resistor 344 and the ground point together with a diode 345 having the ground point side as an anode. The other input side of the NAND circuit 342 is connected to the positive side of the power supply 14 and is pulled up, and the output side of this NAND circuit 342 is connected to the cathode of the light emitting diode 8 via inverters 347 and 348. There is.

According to such a lighting circuit 12, when the switch 16 is operated to be turned on for a short time, the output of the NAND circuit 341 is inverted and the capacitor 343 is instantaneously discharged and charged. To start. The NAND circuit 341 has an L level output, and as a result, the output of the inverter 348 also has an L level output, and a drive current flows through the light emitting diode 8 to light it. The lighting of the light emitting diode 8 depends on the discharge time of the capacitor 343, and after a certain time T, for example, about 5 minutes, the drive current is released and the turn-off time is regulated, so that the power supply 14 is consumed. This can be prevented, and the life of the battery can be extended when a battery is used for the power supply 14.

A golf swing check using this golf swing check device will be described. As shown in FIGS. 6A and 6B, the golf swing check device 44 according to the present invention is installed together with the ball 42 corresponding to the virtual swinging shaft 40 of the trainee 38. The angle of the golf swing check device 44 is set such that the angle of the seat 30 is adjusted so that the spot light 6 falls within the sight line of the trainee 38. The practitioner 38 addresses at that position and, as shown in FIG. 7, places the spot light 6 in the line of sight and swings up the club 46, that is, backswings, and keeps the spot light 6 away from the line of sight. Swing down club 46. Even when the club 46 is applied to the ball 42, the practitioner 38 rotates the club 46 without separating the line of sight from the spotlight 6. As a result, since the line of sight of the swing is fixed to the spotlight 6, the line of sight and the swing are in a linked state, and the swinging motion is performed with the swing axis 40 as the center of rotation. When this kind of practice is performed several times, the practitioner can be aware of the swing shaft 40, and can acquire rotational movement about the swing shaft 40 in a short time.

In addition, for a practitioner who has sensed the swing axis 40, when he or she swings while confirming the spot light 6 as well, the spot light 6 changes to (A) and (B) in FIG. As shown, it can be confirmed to move in the directions indicated by arrows a, b, c, and d. The moving direction of the spot light 6 and the moving direction of the swing shaft 40 are the same, and the moving amount thereof indicates the swing of the swing shaft 40. In FIG. 8, the shape of the translucent portion 28 shows the movement allowable range of the spot light 6, and it can be set arbitrarily, but the higher the advanced person, the smaller the movement range is. In the embodiment, the movement allowable range of the spot light 6 in the translucent portion 28 indicates that the movement of the line of sight is about 10 cm in an actual swing. Spot light 6 goes out. Therefore, if the swing practice is repeated so that the spotlight 6 can be surely seen even when the swing is in the middle of the swing, it means that the swing motion can be performed around the swing axis 40, and the proper swing can be easily performed by the repeated practice. You can get it.

Then, the correction of the swing axis 40 which the trainee 38 has acquired is a shortcut to improving golf such that the ballistic direction is a straight line, but accurate swing reduces fatigue. It is possible to prevent unnecessary stress from adversely affecting the body, which is beneficial for health.

Further, in the embodiment, the chuck of the swing of the swing shaft 40 in the lateral direction has been described. However, by displacing the installation position of the check device 44 in the lateral direction or changing the height, the front and rear of the practitioner can be changed. It can also be used to check the shake in the direction.

In the example, the circular light-transmitting portion 28 is set on the light-transmitting plate 20, but as shown in FIG. 9A, the small circle portion is projected in the left-right direction. The non-circular light-transmitting portion 28 may be used, and the shape of the light-transmitting portion 28 may reflect the habit of a professional golfer or the like. Then, preparing a plurality of translucent plates 20 having different sizes and areas of the translucent parts 28 and exchanging them appropriately is useful for practice according to the size and location of the club.

In addition, as shown in FIG. 9B, scale lines 48 having a lattice shape are formed at regular intervals on the translucent plate 20 without providing the light shielding part 30, and the scale lines 48 are formed. Therefore, the moving amount of the spot light 6 may be quantitatively grasped. Quantitatively confirming the amount of movement of the spot light 6 as described above is useful for correcting the swing of the swing shaft 40.

Further, as shown in FIGS. 10A and 10B, the light transmitting plate 20 includes a light shielding plate 52 having a light transmitting window 50 formed on the light transmitting plate 20, and the light transmitting portion 28. May be formed, and the shading plate 52 having an arbitrary transparent window 50 may be replaceable.

Further, as shown in FIGS. 11A and 11B, a scale line 54 is formed on the scale line 54, and a light shielding plate 52 having a light transmitting window 50 formed thereon is overlapped to overlap the light transmitting portion. 28 may be formed.

When practice is performed using this golf swing check device, rotational movement around the swing axis can be recognized with a little practice, and even a golf inexperienced person can acquire the golf swing in a short time, It was confirmed that it was possible to fly straight.

In the embodiment, the portable and small golf swing check device has been described. However, the golf swing can be similarly checked with a large fixed type golf swing check device. It is not limited to one.

Further, although the swing check using the ball has been described in the embodiment, the golf swing check device of the present invention can be used for practicing smoldering, and is sufficient for acquiring the swing centering on the swing axis. effective.

[0033]

[Effect of device]

 As described above, according to the present invention, since the line of sight is fixed to the spot light and the swing is performed, the rotational movement about the swing axis can be easily and quickly acquired by one person's practice, and the swing axis swings. Can be easily corrected.
