Description

Golf club equipped with device for correcting golf pose}

The present invention relates to a golf club, and more particularly, to a golf club equipped with a golf posture corrector to make accurate hits during a swing / putting operation.

Golf is a game in which golf balls are used to put golf balls into distant hole cups, but they are only a small number of sports. However, golf is becoming more popular as income levels and living standards improve.

However, in order to hit the golf ball accurately using various golf clubs, the golf swing or putting posture must be correct, and the golf club must learn the correct swing or putting posture and the sense of hitting because it must hit the desired position of the golf club head accurately. I try hard to

In particular, the swing motion consists of two rotations of the body and one swing of the arm. The wrist also rotates according to the swing of the arm, as shown in FIG. The club head rotates at a maximum of 180 degrees.

At impact, the golf ball must reach the desired location on the clubface, allowing the golf ball to fly in the desired direction. When the club face and the golf ball are at right angles at impact, the golf ball will fly in a straight direction. If the club face and golf ball are at an acute or obtuse angle, they will be sliced or hooked.

On the other hand, in the case of an experienced golfer to check the state of the club face that the golf ball touches at impact, and see the shape of the golf ball flying after impact to recognize the problem of his swing posture, but this is also not perfect, moreover beginners At impact, his eyes often don't face the clubface or golf ball, so he doesn't easily recognize the exact RBI and his swing posture at that time.

This phenomenon occurs equally / similarly even when putting golf.

Therefore, it is an object of the present invention to provide a golf club equipped with a golf posture correction device that allows the golfer to easily check / hit his swing position by visually confirming the hitting point.

It consists of a battery. On the other hand, a circuit such as that shown in FIG. 3 for cross lighting two or more lamps may be integrated in a printed circuit board.

In addition, the golf posture correcting device 40 includes a battery case 23, a rod 27, and a rod 27 for protecting electrical components (LEDs, circuits (or printed circuit boards), and batteries) from external shocks. It includes a connecting member 26 for connecting to the battery case 23 or the shaft 22. The printed circuit board may be located in the connecting member 26 or in the rod 27 and the connecting member 26. The rod 27 is provided with two or more LEDs 28 integrated on a printed circuit board. In this embodiment, one green LED 28a and three red LEDs 28b, 28c, 28d). In addition, switches 30a, 30b, and 30c for selecting any one of the red LEDs are mounted.

The rod 27 is provided on a surface perpendicular to the club face 21 of the shaft 22 and the club head 29. In particular, the rod 27 having a plurality of cross-illuminated LEDs 28 is not perpendicular to the upper edge 29a of the head 29 but has a β angle (hereinafter referred to as a beta angle) toward the shaft 22. It is tilted (about 5 to 10 degrees), which prepares and mounts the angle jig. The reason why this beta angle is necessary will be described later with reference to FIGS. 4 and 5. Next to the LED of the rod 27, switches 30a, 30b, and 30c for selecting any one of the plurality of LEDs are installed.

The battery case 23 is to be replaced by the battery through the opening and closing portion (not shown) on one side, the through-hole is formed on one side of the battery case 23 is connected through this through-hole (not shown) Power is supplied to the printed circuit board in the member 26. In addition, the battery case 23 is provided with a power switch (not shown) for determining the supply / cutoff of the battery and a switch (not shown) for adjusting the lighting cycle of each LED, the position of these switches is not necessarily limited thereto. It may be provided on the connecting member 26, the rod 27 or the shaft 22 without.

First, the cross lighting circuit will be described with reference to FIG. 3. The cross lighting circuit is a switch for controlling the lighting cycle of each LED and a power switch connected to the integrated circuit module U1 and the control integrated module U1 for controlling cross lighting to determine supply / disable of the battery BT1. It is connected to the switch module (SW1) and the control integrated module (U1) made comprises a LED selection switch module (SW2) for selecting any one of the plurality of LEDs. An oscillation circuit can be used as the control integrated module U1, and in this embodiment, the IC chip LM555 is used as the oscillation circuit.

When using the IC chip LM555, the green LED 28a connected to its terminals 3 and 4 is always on, and when the switch 30a is connected in the LED selection switch module SW2, the first red LED 28b is connected. ) Lights up. When the switch 30b is selected, the second red LED 28c is turned on. When the switch 30c is selected, the second red LED 28d is turned on. When the green LED and the red LED at a long distance are selected, the crossing width of the traces they draw is large, and when the red LED at a close distance is selected, the crossing width of the trace is small. It may be appropriately selected according to the convenience of.

When the terminal 2 of the control integrated module U1 is connected to the capacitor C3 by the switch module SW1, the cross lighting period of the green LED 28a and the selected one red LED becomes long, otherwise the cross lighting is performed. The cycle becomes shorter.

Now with reference to Figure 4 looks at the operation of the golf club equipped with a golf posture correction device according to the present invention. Reference numeral 21 denotes a clubface, reference numeral 27 denotes a rod on which an LED is installed, reference numeral 31 denotes a shaft axis, reference numeral 32 denotes a red LED that lights up, and reference numeral 33 denotes a green LED that lights up. . And the solid line shows the projection on the ground of the trace of the green LED according to the swing motion, the broken line shows the projection on the ground of the trace of the red LED according to the swing movement, and the dashed-dotted line shows the projection on the ground of the trace of the shaft.

When a swinging motion is performed using a golf club equipped with a golf posture corrector according to the present invention, the club head rotates as shown in the drawing according to the swing of the arm and the swing of the cuff joint.

In the section A before the impact, an angle between the trajectory of the shaft and the club face 21 forms an obtuse angle, and the light emitting position of the green LED is above the light emitting position of the red LED. At the moment of impact (point O), their trajectories coincide with each other. At this time, the club face 21 and the trajectory of the shaft form a right angle. That is, the spotting point, the green LED lighting position and the red LED lighting position coincide. After the impact, the trajectory of the shaft and the angle formed with the club face 21 form an acute angle, and the light emitting position of the green LED is below the light emitting position of the red LED. Therefore, when the user fixes the gaze to the light emission traces of the green LED and the red LED during the golf swing operation and hits them at the coincidence point, the user can make an accurate hit. If there is a problem with the swing posture of the user and the impact is found in section A or the impact in section B, the swing posture may be corrected according to each situation.

If the green and red LEDs continue to emit light without cross lighting, when their trajectories are adjacent, it is not easy to identify which color of the LED is in which position, and particularly in bright places, it is considerably inferior. Therefore, the golf posture correcting apparatus according to the present invention was to be cross lit.

If the user's swing speed is fast, the cross-lighting cycle of the LED will be less, so the cross-lighting effect of the LED will be shorter. In this case, the cross-lighting cycle of the LED will be shorter. It may be relatively long. Here, the short and long periods of the cross lighting cycle are not determined by the absolute standard, but are determined by whether the LED appears to be cross lit or continuous light when viewed with the naked eye. In addition, the user may recognize the approximate and relative speed of the swing by observing the length of each LED trajectory and the number of lightings within the length.

As mentioned above, the rod 27, in which the green LED and the plurality of red LEDs are installed, has a β angle (about 5 to 10) toward the shaft 22 without being perpendicular to the upper edge 29a of the golf head 29. Degree) was installed inclined. If the rod 27 is installed perpendicular to the upper edge 29a of the golf head 29 without the beta angle, it will be described with reference to FIG. In FIG. 5, the same reference numerals as used in FIG. 4 are used for the same components as in FIG. 4. However, the rod 27 shown in FIG. 5 forms a right angle with the top edge of the club face 21.

In FIG. 5, the intersection point of the trace of the green LED and the trace of the red LED is a point O ′ positioned before the intersection point O of FIG. 4. The user must follow the trajectories of both LEDs and hit at their intersection point O to recognize that they are the correct hits. However, when the impact occurs at the point O, the shaft trajectory indicating the traveling direction of the club face 21 and the golf ball does not form a right angle but forms an obtuse angle. In other words, the golf ball will be bent to the right because the hook is hit instead of the exact hit. If the user hits the golf ball in the section C 'because the user wants to fly the golf ball to the left, in some cases (when impacted at point O), the golf ball may fly in front of the user's intention. That is, as shown in Figure 5 rod 27 is difficult to correct the swing posture correctly using a golf club equipped with a swing correction device to be perpendicular to the top edge of the club face 21.

When the golf posture correction device is mounted without maintaining the beta angle, the swing posture correction is not correct because the swing includes rotation of the wrist joint from a certain point in addition to the swing of the arm. On the other hand, the timing at which the wrist joint rotates, the degree of rotation of the wrist joint, and the like vary depending on the person. Therefore, the inventor of the present invention obtained the rotation angle of the wrist joint by experimenting the degree of wrist joint during the actual swing operation, this value is in the range of 5 to 10 degrees as described above.
