Description

Golf putting practice device {A DEVICE FOR TRAINING OF GOLF PUTTING}

The present invention relates to a golf putting practice apparatus, and more particularly, by providing the exerciser with the speed and movement information of the putter head during the back swing and down swing of the practice during golf putting practice, correcting the swing posture of the exerciser, It relates to a golf putting practice device that can improve the putting accuracy and stability.

Golf is a sports game in which golf balls such as woods, irons, and putters are used to move a golf ball from the tee box to the vicinity of the hole and finally push the golf ball into a hole cup.

At this time, none of all kinds of golf clubs and various shots are important, but the play and putting around the green are very important for amateur golfers and professional golfers who have intermediate or advanced skills to reduce the number of hits. Get mad.

In general, when putting in golf, it is the most difficult process among golfing games, because it is necessary to hit the ball with sensitivity after grasping the condition of the grass, the slope, the curvature, etc. accurately. In particular, putting is most easily influenced by the psychological state of the player as well as external factors such as the ever-changing state of the green (Yips phenomenon), so not only amateur athletes but also famous pro athletes have considerable difficulty in putting. There are many cases.

In addition, even considering the number of putters used per game, assuming a putt of two holes per hole on an 18-hole par 72 golf course, a total of 36 putts per round will result, which is half of the overall number of strokes. That's a lot of weight. Therefore, in reality, the number of hits using the putter is considerably higher than the total number of hits made using golf clubs other than the putter on the teeing ground, fairway, and bunker. Decrease plays a very important role in determining the performance of the golf game of the day.

On the other hand, it is important for golf to maintain consistency in most of the plays, and maintaining a consistent stroke strength and rhythm even in putting is an absolute weight in improving golf skills and reducing the number of hits.

For example, the most common and persistent problem for golfers when putting is a short putt where the ball does not reach the hole cup by putting less than the required force. Putting the ball past the hole cup will give the ball a chance to hole in (never up, never in), so a short putt where the ball does not reach the hole cup will inevitably lead to an increase in the number of hits.

The biggest reason for golfers to make short putts may be the lack of skill and psychological timidity. However, since the center of gravity of the existing putters is located at the back of the hitting surface, the follow-throw after the hit is small enough to provide sufficient impact. This is also because the ball cannot be delivered to the ball.

In addition, the putting is completed through a very sophisticated movement, and if the golf ball, the center line of the golf ball and the hole cup are not exactly positioned on the line, or the putter does not hit the golf ball at a right angle, the correct putting cannot be expected.

After all, while putting can expect the highest degree of perfection in stable and precise movements acquired by practice, putting correction devices that can master these sophisticated movements are generally not used.

In this situation, various assistive devices for putting practice have been released, but only a certain distance is provided with a hole cup and the bottom is formed of a material having characteristics similar to the green of the golf course to practice hitting the actual golf ball into the hole cup. Most of them were made, and no device was developed to practice putting strokes or to maintain strokes regardless of whether a golf ball was used.

Referring to these drawings, the golf putting practice apparatus 100 according to the present invention is a golf mat 110 on which a golf ball is seated, and a putting guide part 120 formed around the golf ball seating part 111 of the golf mat 110. ), A head moving speed measuring unit 130 installed on one side of the putting guide unit 120 to measure the moving speed of the putter head (H) during the backswing and downswing of the golf putter, the head moving speed measuring unit 130 ) Is installed on one side of the head moving distance measuring unit 140 and the head moving speed measuring unit 130 and the head moving distance measuring unit 140 to measure the moving distance of the putter head (H) from the putter head It may be configured to include a control unit 150 for receiving the moving speed of the (H) and the moving distance of the putter head (H) to the display unit 160.

That is, the golf putting practice apparatus 100 according to the present invention forms a putting guide part 120 around the golf ball seating part 111 of the golf mat 110, and the exerciser puts the center of the putting guide part 120 when practicing putting. By putting the golf ball on the golf ball seating portion 111 of the putting guide portion 110 to perform the putting practice based on the position, it is possible to conveniently improve the skill of putting, the putting guide portion 120 The head moving speed measuring unit 130 and the head moving distance measuring unit 140 are respectively installed at one side of the head moving speed measuring unit 130 and the head moving distance measuring unit 140 from the putter head (H). Install the control unit 150 to receive the moving speed and the moving distance of the putter head (H) to provide the exerciser and moving distance information of the putter head during the back swing and downswing to the exerciser through the display unit 160 By doing this, the practitioner And to identify and analyze, and to be able to swing and correct your posture and stance stroke, improves putting accuracy and reliability.

Here, the head moving speed measuring unit 130 may measure the moving speed of the putter head H by recognizing the putter head H as an object, for example, in a 3D image received from an image sensor. have. That is, the moving speed of the putter head H may be detected by using the pixel number data of the image photographing the position of the putter head H at a predetermined time interval.

In addition, the head moving speed measuring unit 130 may analyze the moving speed of the putter head H through frequency analysis as a method of measuring a speed of a target using a radar sensor.

For example, suppose that an object that is far from the radar is at a distance R. The frequency waveform over time is determined, and when a linearly frequency-modulated signal is transmitted, it is reflected by the object at the distance R and 2R / c. After a time delay is received on the radar. Where R is the distance to the target and c is the speed of light (3 × 10 ⁸ m / s). At this time, if the transmitted signal and the received signal are mixed with each other, the difference frequency can be obtained. The frequency is expressed by Equation 1 below.

[Equation 1]

The distance R may be determined by substituting Equation 2 below based on the difference frequency information calculated in Equation 1.

[Equation 2]

In addition, the radar sensor may be a continuous wave (CW) radar or an FM-CW radar. The radar sensor can use a fixed transmission frequency to measure the speed of a moving target. The radar sensor can measure the speed of a moving target based on the Doppler frequency shift.

The head moving distance measuring unit 140 analyzes the time and speed of the photographed image of the putter head H obtained from an image sensor or a small camera, for example, to determine the moving distance of the putter head H. It can be measured.

The shape or structure of the putting guide portion 120 is not particularly limited as long as it surrounds the golf ball seating portion 111 and allows a practitioner to grasp the putting position conveniently, for example, the golf mat 110. The golf ball seating portion (111) surrounding the periphery of the golf putter back swing direction may be made of a horseshoe shape.

Here, the size of the horseshoe-shaped putting guide portion 120 is not particularly limited as long as the size can be seated in the center of the golf ball, preferably putter head when practicing practice putting around the general putter head The size of the width direction of the golf mat 110 can be formed to be 10 to 20cm so as to be a reference position for positioning.

Meanwhile, the putting guide unit 120 detects the movement of the golf putter head H on both sides of the golf mat 110 in the width direction and transmits the movement to the control unit 150 and the display unit 160. Sensors 121 and 122 may be formed. Therefore, the exerciser during the putting practice can effectively correct the putting position and the putting posture by grasping the movement of the putter head through the display unit 160 or the like.

Here, the controller 150 analyzes the motion information of the golf putter head H received from the motion sensors 121 and 122 so that the golf putter head H is on the upper side of the putting guide unit 120. If it is determined that the only movement, the warning signal can be transmitted to the display unit 160 to display. Therefore, the practitioner can determine that the position of the putter head (H) is wrong when putting in a simple manner, and can correct the putting position.

If the moving speed of the putter head H is less than twice the moving speed of the downswing, the control unit 150 displays the size of the moving speed at the time of the backswing, the moving speed size at the downswing and the warning signal. It may be transmitted to the unit 160 for display.

In other words, the exercise speed (V1) of the putter head (H) during the backswing of the practice during putting practice is more than twice the movement speed (V2) of the putter head during the downswing, in order to control the accuracy of the putting and the movement distance of the golf ball. It can be an optimal speed ratio. Therefore, in order to enable the trainee to recognize and acquire such a speed ratio, the control unit 150 may perform the backswing when the moving speed of the putter head H is less than twice the moving speed of the downswing. The movement speed magnitude and the movement speed magnitude information and the warning signal may be transmitted to the display unit 160 during downswing.

In addition, the control unit 150 has a horizontal movement distance (D1) during the backswing of the putter head (H) and the horizontal movement distance (D1) when downswing based on the golf ball seating portion 111 than the range of 23 to 27cm When the size is large or small, the horizontal moving distance D1 at the backswing and the horizontal moving distance D1 at the downswing may be transmitted to the display unit for display.
