Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a golf club, and more particularly, to a golf club with a golf posture correcting device that can hit the golf club accurately when swinging / putting.
[0002]
[Prior art]
Golf is a sport that uses golf clubs to place golf balls in distant hole cups, and it was only a small group of sports, but it has become popular as income levels and living standards improve. This has led to a surge in golfers.
[0003]
Among conventional techniques, in order to correct the golf swing posture, the moment of impact is determined while visually confirming the trajectories of the two lamps that are lit by the inertia force generated during the swing. Yes (see, for example, Patent Document 1).
[0004]
[Patent Document 1]
Korean Utility Model Registration No. 290703 [0005]
[Problems to be solved by the invention]
However, the above-described golf swing posture correcting device has been designed in view of the fact that the wrist rotates with the rotation of the body during the swing. In addition, since the two lamps are lit continuously, there is a problem that it is difficult to visually confirm both loci when these lamps are close to each other.
[0006]
To hit the golf ball accurately using various golf clubs, the golf swing or putting posture should be accurate and hit the golf club head exactly at the desired position, so the golfer must swing correctly. Or you will endeavor to learn the putting posture and the feeling of striking.
[0007]
In particular, the swing motion consists of two body rotations and one arm swing, but the wrist also rotates due to the arm swing, and the club head also rotates as shown in FIG. The rotation angle of the club head is 180 degrees or more at maximum.
[0008]
If the golf ball does not touch the desired position of the club face at the time of impact, the golf ball cannot be thrown in the target direction. When the club face and the golf ball are perpendicular to each other at the time of impact, the golf ball flies in a straight direction, and when the club face and the golf ball become an acute angle or an obtuse angle, it becomes a slice or a hook.
[0009]
On the other hand, in the case of a skilled golfer, the state of the club face touched by the golf ball at the time of impact is visually observed, and the problem of the own swing posture is recognized by looking at the state of the golf ball flying after impact. This is not perfect. Furthermore, since beginners often do not have their line of sight toward the club face or golf ball at the time of impact, it is not possible to easily recognize the exact hit point and the problem of their swing posture at that time. Such a phenomenon occurs in the same / similar manner during golf putting.
[0010]
Therefore, an object of the present invention is to provide a golf club with a golf posture correcting device that allows a golfer to check a hitting point with his / her eyes and easily practice / correct his / her swing posture.
[0011]

FIG.
[0014]
Referring to FIG. 2, a golf club 20 according to an example of the present invention includes a club head 29 having a club face 21 and a shaft 22 connected to a hosel. It is installed. The golf posture correcting device 40 includes two or more LEDs 28 that cross-light at a constant cycle, a circuit (FIG. 3) that cross-lights two or more LEDs 28 at a constant cycle, and a battery that supplies power to the cross-lighting circuit. Composed. On the other hand, a circuit as shown in FIG. 3 for cross-lighting two or more lamps can be integrated on a printed circuit board.
[0015]
Such a golf posture correcting device 40 includes a battery case 23 and a rod 27 that protect electrical components (LED, circuit (or printed circuit board) and battery) from external impacts, and the rod 27 as a battery case. 23 or a connecting member 26 connected to the shaft 22. The printed circuit board can be located in the connecting member 26 or in the connecting member 26 with the rod 27. 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 spaced apart from each other by a predetermined interval are provided. , 28d. Then, switches 30a, 30b and 30c for selecting any one of the red LEDs are mounted.
[0016]
The rod 27 is installed on a surface perpendicular to the club face 21 of the shaft 22 and the club head 29. In particular, the rod 27 in which a plurality of LEDs 28 that are cross-lit are installed is not perpendicular to the upper edge 29a of the club head 29, and is about β angle (hereinafter referred to as “beta angle”) toward the shaft 22 (about 5 to 10). Degree), this is an angle jig prepared and mounted. The reason why this beta angle is necessary will be described later with reference to FIGS. In addition, switches 30a, 30b, and 30c for selecting any one of the plurality of LEDs are installed near the LED of the rod 27.
[0017]
The battery case 23 is installed on the shaft 22, but is detachably fixed to the shaft 22 through fastening screws 25 a and 25 b inserted into the holes of the fastening plate 24. The battery can be exchanged through an opening / closing part (not shown) on one surface of the battery case 23, and a through-hole (not shown) is formed on one side of the battery case 23, and the connecting member 26 is passed through this through-hole. Power is supplied to the printed circuit board. The battery case 23 is provided with a power switch (not shown) for determining supply / cutoff of the battery and a switch (not shown) for adjusting the lighting cycle of each LED. However, the present invention is not necessarily limited thereto, and may be positioned on the connecting member 26, the rod 27, or the shaft 22.
[0018]
First, the cross lighting circuit will be described with reference to FIG. The cross lighting circuit includes an integrated circuit module U1 that controls cross lighting, a power switch that is connected to the control integrated module U1 to determine supply / cutoff of the battery BT1, and a switch module that adjusts the lighting cycle of each LED. The LED selection switch module SW2 is connected to the SW1 and the control integrated module U1 to select one of the plurality of LEDs. In the control integrated module U1, an oscillation circuit can be used. In this embodiment, an IC chip LM555 is used as the oscillation circuit.
[0019]
If the IC chip LM555 is used, the green LED 28a connected to the terminal 3 and the terminal 4 is always lit. In the LED selection switch module SW2, the first red LED 28b is turned on when the switch 30a is connected, the second red LED 28c is turned on when the switch 30b is selected, and the second red LED is turned on when the switch 30c is selected. The LED 28d is turned on. If a green LED and a red LED at a long distance are selected, the crossing width of the locus will be large, and if a red LED at a short distance is selected, the crossing width of the locus will be small. It can be appropriately selected according to the convenience of the user.
[0020]
If the terminal 2 of the control integrated module U1 is connected to the capacitor C3 by the switch module SW1, the cross lighting cycle between the green LED 28a and the selected one red LED becomes long, otherwise the cross lighting cycle becomes short.
[0021]
In addition, with reference to FIG. 4, operation | movement of the golf club with the golf posture correction apparatus by this invention is demonstrated. In the reference numbers, 21 is a club face, 27 is a rod on which an LED is installed, 31 is a shaft shaft, 32 is a red LED that is lit, and 33 is a green LED that is lit. The solid line is a projection view of the green LED locus following the swing operation on the ground, the wavy line is the projection view of the red LED locus according to the swing operation on the ground, and the alternate long and short dash line is a projection view of the shaft locus on the ground. .
[0022]
When the golf club with the golf posture correcting device according to the present invention is used to perform a swing motion, the club head rotates as shown in the drawing by the swing of the arm and the swing of the wrist joint.
[0023]
In the section A before impact, the shaft locus and the club face 21 form an obtuse angle, and the light emission position of the green LED is higher than the light emission position of the red LED. These loci coincide at the impact moment (point 0), and at this time, the loci of the club face 21 and the shaft form a right angle. That is, the hit point matches the lighting position of the green LED and the lighting position of the red LED. After impact, the shaft trajectory and the club face 21 form an acute angle, and the light emission position of the green LED is lower than the light emission position of the red LED. Therefore, the user can accurately hit the ball by fixing the line of sight to the light emission traces of the green LED and the red LED while performing the golf swing operation and hitting at a point where these match. If it is found that there is a problem in the swing posture of the user and the impact is made in the section A or the section B, the swing posture can be corrected according to each situation.
[0024]
If the green LED and the red LED continue to emit light instead of being cross-lit, it is difficult to identify which color LED is in what position when these trajectories are adjacent to each other. Therefore, the golf posture correcting device according to the present invention is always cross-lit.
[0025]
When the swing speed of the user is fast, the effect of cross-lighting is reduced if the cross-lighting cycle of the LED is long, so the cross-lighting cycle of the LED is shortened. When the swing speed is not relatively fast like a beginner, the LED cross-lighting cycle may be lengthened. Here, the length of the crossing lighting cycle is not an absolute reference, and is determined depending on whether the LED can be seen by cross lighting or in a continuous light emission state. Then, the user can recognize the approximate and relative speed of the swing by observing the length of each LED locus and the number of lighting within the length.
[0026]
As described above, the rod 27 on which the green LED and the plurality of red LEDs are installed is not perpendicular to the upper edge 29a of the club head 29 and is inclined by about a beta angle (about 5 to 10 degrees) toward the shaft 22. Was installed. If the beta-angleless rod 27 is installed perpendicularly to the upper edge 29a of the club head 29, what problems will occur will be described with reference to FIG. In FIG. 5, the same reference numerals as in FIG. 4 are used for the same components as in FIG. However, the rod 27 shown in FIG. 5 forms a right angle with the upper edge of the club face 21.
[0027]
In FIG. 5, the point where the locus of the green LED and the locus of the red LED intersect is a point 0 ′ located before the intersection 0 of FIG. If the user does not hit at these intersections 0 according to the trajectory of both LEDs, it cannot be recognized with an accurate hit. However, when impact is made at point 0, the club face 21 and the shaft locus indicating the traveling direction of the golf ball form an obtuse angle that is not perpendicular. That is, the golf ball turns to the right and becomes a slice hit which is not an accurate hit. If the user wants to turn the golf ball to the left and hits the golf ball in the section C ′, the golf ball flies to the front unlike the user's intention in some cases (when impacted at point 0). Can go in. That is, as shown in FIG. 5, it is difficult to correct the swing posture correctly in a golf club with a swing correction device in which the rod 27 is perpendicular to the upper edge of the club face 21.
[0028]
Thus, if the golf posture correction device is installed without maintaining the beta angle, the reason why the swing posture correction is not accurate is that the swing includes the rotation of the wrist joint from a certain point in addition to the swing of the arm. is there. On the other hand, the time at which the wrist joint rotates, the degree of rotation of the wrist joint, and the like vary from person to person. In addition, the inventor of the present invention obtains the rotation angle of the wrist joint by experiments on the degree of rotation of the wrist joint during the actual swing operation, and the value is in the range of 5 to 10 degrees as described above.
