Description

[Detailed Description of the Invention] This invention relates to a golf swing correction device.

When learning the basics of golf, it is well known that there are detailed basic movements even when looking at a single swing movement. For example, in a top swing state, the hips must be rotated at 45 degrees, the upper body must be rotated at 90 degrees, and the club must be pointing at the target at that time.

However, the most difficult and unstable thing for beginners to grasp when it comes to these basic movements is
This is the position of the hands during this top swing, and the position and direction of the club head at that time. In this case, even if the player's posture is corrected by reflecting it in a mirror, the player must stare at the ball while swinging, making it difficult to observe the player's posture, such as top swing.

In view of the current situation, this invention aims to provide a swing correction device that can self-diagnose whether or not the swing motion is being performed normally during the swing.

That is, this invention is a golf swing correction device in which a detection device is disposed along the swing trajectory to detect the passage of a moving object, which irradiates a light beam that can be distinguished from external light and detects the golf club of the irradiated light. a detection device equipped with a light projector and a detector that detect reflected light from This invention relates to a golf swing correction device, characterized in that the detection device is constituted by a vertically movable pedestal that supports the adjuster with the detection device attached thereto.

This idea focuses on the fact that when the swing motion is performed normally, the trajectory of the golf club is almost constant, and by moving the stand up and down to a specific position on this almost constant trajectory. The position of the golf club is set, a light beam that can be distinguished from external light is emitted, and the reflected light of the emitted light by the golf club is detected.
In this case, either the irradiation light is made directional, or the detection field of the detector is narrowed down, and it is detected only when the golf club passes a specific position on the above-mentioned almost constant trajectory. The light projection direction and the detection direction are adjusted so that the detection signal is notified to the player by sound or light.

This makes it possible to judge while swinging whether or not the swing motion is being performed normally.

The projector used in this invention is designed to emit light that can be distinguished from external light, such as infrared light, laser light, strobe light, etc., so that it can be used outdoors. The detector is also adapted to detect only the irradiated light beam accordingly. Further, as an adjuster for adjusting the pointing direction of the projector and the detector, an adjuster that can be operated remotely and is used, for example, in an electric remote control mirror of an automobile can be used. In this case, if the projector and the detector are formed integrally and their pointing directions are adjusted simultaneously using one adjuster, the adjustment operation becomes extremely easy. Furthermore, as the operating end of the regulator, a foot switch that can be operated at the player's feet is used.

It is convenient for the direction in which the player's foot operates the adjuster to intuitively match the pointing direction of the projector, which is actually changed and controlled by it, in terms of front, rear, left and right.

Hereinafter, a specific configuration of this invention will be explained based on an illustrated embodiment.

Fig. 1 is an external perspective view showing the main parts of an embodiment of the device according to this invention, Fig. 2 is a side view of the main parts, Fig. 3 is a front view thereof, and Fig. 4 shows how the regulator can be connected remotely. FIG. 5 is a plan view of a foot switch to be operated, FIG. 5 is an explanatory diagram of use when an embodiment of the device according to this invention is arranged in a predetermined positional relationship, and FIG. 6 is a diagram showing the position of an exemplary golf club at the top swing position. FIG. 3 is an explanatory diagram of the arrangement of this embodiment device that detects the direction and position of the club shaft in this state.

In these figures, a detection device C is attached to the tip of a vertically movable gantry A via an adjuster B, and a projector 1 and a detector 2 are attached to the detection device C so that their front surfaces are the same. It is installed so that it is oriented in the direction.

The detection device C is attached to the front surface of the adjuster B via a ball joint 4 at the center of a bracket 3 fixed to the bottom surface of the detector. 2, a projector 1 having four light emitters is provided on the circumferential side of the detector 2, respectively. By simply adjusting the pointing direction of this detection device C, the pointing directions of the projector 1 and the detector 2 can be adjusted simultaneously.

The adjuster B is the same as the adjuster used in electric remote control mirrors of automobiles. That is, the regulator B has a first drive rod 5 and a second drive rod 6 that are driven back and forth.
A second driving rod 5 is connected to the bracket 3 on the side of the ball joint 4, and a second driving rod 6 is connected to the bracket 3 below the ball joint 4, and the second driving rod 6 is connected to the bracket 3 below the ball joint 4.
is made to swing vertically and horizontally around this ball joint 4.

The first drive rod 5 and the second drive rod 6 are configured to convert rotational motion into linear motion using a motor, rack, and pinion (not shown) housed in their rear housings.

The regulator B is operated by a foot switch 7 that remotely controls it. That is, when the right button 8 of the foot switch 7 in FIG. This time, it is driven in the opposite direction to rotate the detection device C to the left. When the upper button 10 is pressed, the second drive rod 6 moves forward to rotate the detection device C upward, and when the lower button 11 is pressed, it is driven in the opposite direction and rotates the detection device C downward. make it move. In this case, the foot switch 7 is configured such that it will not turn on if the operation buttons 8 to 11 are pressed at the same time.

The floodlight 1 uses an infrared light-emitting diode modulated at approximately 4KHz as a light emitter, and its irradiation field is approximately 1.5 m away from the irradiation surface of the golf club G when the floodlight 1 is at most 1.5 m away from the irradiation surface of the golf club G. The irradiation surface is focused so that it is a circle with a diameter of about 20 cm.

The detector 2 includes a condensing lens 12 attached to its front surface and an infrared phototransistor 13 attached to its focal position, and detects only the reflected light from the golf club G of the irradiated light. is output as an electrical signal. In this case, depending on the selection of a specific position on the swing path R of the club G shown in FIG. 5, the passing speed of the club at that specific position may be extremely fast, and therefore the amount of detected light may be extremely small. . In preparation for such a case, in this detector 2, the amplification factor of the detection signal is made variable. Furthermore, even if the golf club G slightly deviates from the model swing trajectory R, the detector 2 detects the golf club G within a range where the deviation is allowable, as shown in FIG. As shown, the club shaft G
Even if the grip G' deviates from its exemplary position within a range of 5 degrees in the front and back, up and down, centering on the grip G', this is detected.

Next, how to use this embodiment device will be explained based on FIGS. 5 and 6.

For example, when it is desired to correct the position of the golf club G at the top swing position, as shown in FIG.
Place it at a distance of 1.5m, and place the alarm D behind the ball 14. Further, the foot switch 7 is arranged at a desired position where the person operating it can easily operate it. For example, when the player himself operates this, it is placed, for example, in the middle position between both feet.

The alarm D converts the detection signal of the detector 2 into sound or light to notify the player, and when it outputs light as a detection sign, it is sent to the rear of the ball 14. The notification signal can be confirmed even when the player swings while staring at the ball 14.

Once positioned in this way, follow the golf instructor's instructions to create a typical top-swing position, drive adjuster B to detect golf shaft G at this time, and alarm D is activated. Adjust accordingly. When set in this way, as shown in FIG.
When the club shaft G comes to a position approximately equal to this exemplary top swing position, when the club shaft G reaches a position approximately equal to this exemplary top swing position, the annunciator D is activated to notify the user of this.

Incidentally, the power source for driving the device of this embodiment is installed, for example, inside the detection device C or at a suitable location on the pedestal A so that it can be used outdoors.

Although this invention is constructed as described above, it is clear that the construction is not limited to the illustrated embodiment.

As explained above, this invention supports the adjuster and the detection device on a vertically movable pedestal.
By adjusting this, it can be set at any position on the golf swing trajectory, so compared to conventional methods that detect and confirm the swing trajectory only at fixed points, it is possible to set it at any desired point along the golf swing trajectory. This allows you to check your swing, which allows you to correct your swing. Furthermore, since the golf club being swung can be detected even with light rays different from outside light, it can be used outdoors. Furthermore, since the detection signal is notified to the player by sound or light, the player can confirm the detection signal while staring at the ball. Furthermore, since the adjuster is remotely operated at the player's feet, the player can operate the adjuster by himself while taking a model pose.
