In addition, when the golfer sets the target distance of the golf ball through the operation unit 2 in advance, the actual distance of the golf ball put by the golfer compared to the target distance input by the golfer.

The display unit 7 is installed on one side of the main body 1 so that the golfer can grasp his putting state during the putting practice. 5 is a state diagram showing an example of a screen displayed on the display unit 7 of the putting correction and practice apparatus according to the present invention. As shown in the figure, the display unit 7 displays the putting swing trajectory, the putting swing speed, the putting swing tempo, the putting style, the golf ball traveling direction, and the golf ball traveling distance information calculated by the central processing unit 6. Mark it. In addition, the speaker 8 informs the golfer of whether the correct putting or the wrong putting is made with respect to the golfer's putting result.

The following describes how to calculate the swing trajectory of the putter of the central processing unit 6, the angle of the putter at the time of putting, the swing swing tempo, the swing speed at the putt, the direction of the golf ball after the putting, and the traveling distance of the golf ball. .

The swing path of the putter is that the putter starting from the putter detection sensors A-A '(4a, 4a') passes through the putter detection sensors B-B '(4b, 4b') and putter detection sensors C-C '(4c, 4c'). When passing through), putter detection sensor B (4b) and putter detection sensor B '(4b') by calculating the time difference that the putter is detected, to grasp the intermediate trajectory during the backswing of the putter, and putter detection sensor C (4c) And it is possible to determine the final trajectory during the backswing of the putter by calculating the time difference that the putter is detected by the putter detection sensor C '(4c'). In addition, the swing trajectory during the downswing of the putter can also be grasped by the above-described method.

If the putter is detected by the putter detection sensor B (4b) among the putter detection sensors during the back swing of the putter and the putter is not detected by the putter detection sensor B '(4b'), the backswing is biased to the outside of the golfer's body. If the putter is detected only on the putter sensor B '(4b'), the backswing is biased toward the golfer's body. Likewise, in the case of the putter detecting sensor C 4c and the putter detecting sensor C '4c', if the putter is detected by only one sensor, it may be determined that the normal back swing is not made. The same applies to downswing. Therefore, when the square which forms a parallel swing from the posture of the golf ball and the golfer in the backswing and the downswing is not made, the trajectory of the backswing and the downswing can be determined. In addition, the swing trajectory of the putter after impacting the golf ball can be grasped by the method described above by the putter detection sensors D-D '(4d, 4d'). Therefore, the central processing unit 6 transmits the swing track information to the display unit 7 so that the golfer can grasp his swing track.

The speed of the swing is determined by the interval between the putter detection sensors and the detection time of the putter detection sensors. That is, putter detection sensor A-A '(4a, 4a'), putter detection sensor B-B '(4b, 4b'), putter detection sensor C-C '(4c, 4c'), putter detection sensor D-D The distance information between '(4d, 4d') is stored in advance and obtained from the time information detected by the putter detecting sensors 4a, 4a ', 4b, 4b', 4c, 4c; 4d and 4d '. Become. In the case of the backswing, the time when the putter passes the putter detection sensor B-B '(4b, 4b') from the point where the putter leaves the putter detection sensors A-A '(4a, 4a'). The time difference between the putter sensor A-A '(4a, 4a') and the putter sensor B-B '(4b, 4b'). You can calculate the speed.

(Formula 1)

Here, if the putter does not pass the putter detection sensor B-B '(4b, 4b') in the same time, the average of the time passing the putter detection sensor B (4b) and the putter detection sensor B '(4b') by calculating the putter The backswing speed of the putter can be obtained by calculating the difference in the time deviating from the putter detection sensor A-A '(4a, 4a'). In addition, if the putter is detected only by the putter detection sensor B 4b, the backswing speed of the putter may be calculated based on the time when the putter detection sensor B 4b passes.

Similarly, the time at which the putter passes the putter detection sensors C-C '(4c, 4c') is obtained and the putter is putter detection sensors B-B '(4b, 4b') and the putter detection sensors C-C '(4c). The back swing speed of the putter between, 4c ') can be obtained. In this way, the backswing speed of the putter for each section can be obtained, and the total backswing speed can be obtained by the average value of the backswing speed for each section.

On the other hand, the down swing speed of the putter can be calculated by calculating in the reverse direction of the back swing speed described above. That is, the putter detection sensor B-B '(4b, 4b') and the putter detection sensor A-A '(4a, 4a') based on the time when the putter passes the putter detection sensors C-C '(4c, 4c'). The downswing speed for each section of the putter can be calculated by calculating the time point passing by. The total downswing speed can be obtained by calculating the average value of the swing speed for each section. In addition, after the putter impacts the golf ball, the follow swing speed is measured by using the difference between the detection time of the putter sensor A-A '(4a, 4a') and the putter sensor D-D '(4d, 4d') during the down swing. You can get it.

The angle of the putter at the time of putting is determined by the putter detecting sensors A-A '(4a, 4a'). When the putter is downswing and impacts the golf ball, the putter passes the putter sensor A-A '(4a, 4a'), and the putter surface of the putter is at an angle of 90 degrees with respect to the horizontal center line of the base plate 11. In this case, the putter passes through the putter detecting sensor A (4a) and the putter detecting sensor A '(4a') at the same time, so that the putter is simultaneously held by the putter detecting sensor A (4a) and the putter detecting sensor A '(4a'). If detected, it can be seen that the angle of the putter a surface during putting is 90 degrees with respect to the center line. If the putter is first detected by the putter detection sensor A (4a) and then the putter is detected by the putter detection sensor A '(4a') with a slight time difference, it can be seen that the surface of the putter is closed. . At this time, the method of calculating the angle of the putter is the down swing speed of the putter and the distance between the putter detection sensor A (4a) and the putter detection sensor A '(4a'), and the putter detection sensor A-A '(4a, 4a'). By the time difference is detected by the putter can be calculated according to the following formula (2).

(Official 2)

If the angle of the putter obtained in Equation 2 has a positive value, the putter becomes a closed angle with respect to the normal putting angle, and if the calculated putter has a negative value, the putter is a normal putting angle. To become an open angle.

The putting swing tempo is a correct putt, regardless of whether the golfer makes a big swing or a small swing. That is, in the case of a large swing, the swing speed is increased, and in the case of a small swing, the swing speed should be slow. Therefore, the time difference between when the putter is backswinged and downswinged to impact the golf ball should always have a constant value. Therefore, the putting time starting from the putter detection sensor A-A '(4a, 4a') and backswing and downswing back to the putter detection sensor A-A '(4a, 4a') becomes the putting tempo. It is obtained from the time difference between when the putter is backswinged by the sensor A-A '(4a, 4a') and when the putter is backswinged and downswinged and detected by the putter sensor A-A '(4a, 4a') again. Can be.

Putting styles can be divided into normal cases where the putter pushes the ball and abnormal cases when the putter hits the ball. In general, the putter is pushing the ball, the normal putting is done, if the putter hits the ball can be seen as an abnormal impact. This putting style can be understood from the swing speed of the putting. From the above-mentioned back swing speed, down swing speed, and follow swing speed, the speed is compared to determine whether the putter pushes or hits the golf ball at impact. If the backswing speed and the downswing speed are the same as the follow swing speed or within a certain error range, the normal impact is estimated by normal impact.If the backswing speed is the fastest or the downswing speed is faster than the follow swing speed, putter Is estimated to have hit the golf ball is an abnormal impact.

After putting, the direction of the golf ball can be calculated by estimating from the angle of the putter surface of the putter. Since the golf ball proceeds in a direction perpendicular to the putter surface, the golf ball can be estimated from the angle of the putter at the time of putting.

The golf ball travel distance after the putting can be calculated by the following formula from the friction coefficient according to the green state input by the golfer, the speed of the golf ball and the travel distance of the golf ball.

(Official 3)

Equation 3 above is a law of conservation of kinetic energy and uses the principle that the kinetic energy of a golf ball is converted into friction energy. Therefore, the formula for calculating the travel distance S of the golf ball from (Formula 3) is as follows.

(Official 4)

Here, the speed of the golf ball is a value calculated by the above-described method, the friction coefficient is selected from the friction coefficient value of the actual green input in advance and substituted into the formula. That is, when the golfer selects any one of three conditions of slow, normal, and fast of the green state input switch provided in the operation unit, the friction coefficient corresponding to the selected state can be obtained by the following formula.

(Formula 5)

The above-described green speed (formula 5) can be obtained from a method for obtaining a golf course green speed using a steam meter in the actual golf course design. The steam meter is a tool designed to roll a golf ball. The steam meter is inclined at an angle of about 20 degrees with respect to the golf course green. When the golf ball is rolled at a distance of 90 cm along the steam meter from the ground, the golf ball is tilted. Followed down. The golf ball that comes down from the steam meter rolls the green. At this time, the length of the golf ball is measured to determine the green speed. In fact, for the US Open Golf Tournament of the US Golf Association (USGA), the green speed is 3.2m for the fast green, 2.6m for the middle green, it is recommended to have a value of 2m in the slow green, in the present invention The value of speed was adopted as the standard of this US Open Golf Competition. Therefore, the advancing distance of the golf ball can be calculated using the above-described formula.

On the other hand, when the golfer inputs the target distance in advance through the operation unit 2, the central processing unit 6 compares the actual distance and the target distance of the actual golf ball, if the actual travel distance is calculated outside the predetermined error range (8) To sound a beep.

Next, the operation of the first embodiment of the putting correction and practice apparatus according to the present invention by the above-described configuration will be described.

Figure 6 is a state diagram showing the operating state of the first embodiment of the putting correction and practice apparatus according to the present invention. First, the golfer initially sets the golf ball on the first golf ball sensor 3 on the putting mat (11). The putter is then placed on the putter detecting means A-A '(4a, 4a') to set the putting swing. When the putt begins, the putter is backswinged and downswinged again to impact the golf ball. After impact, the golf ball moves forward and at the same time, the putter is followed by a swing to complete one swing.

Putter detection sensor A-A '(4a, 4a'), putter detection sensor B-B '(4b, 4a'), putter detection sensor C-C '(4c, 4c) when the putter is backswinged in one swing. The movement of the putter is detected by '). Also, when the putter is downswinged and impacted after the swing, the putter detection sensor C-C '(4c, 4c'), the putter detection sensor B-B '(4b, 4b'), and the putter detection sensor A-A '( 4a, 4a ') and the putter sensor D-D' (4d, 4d ') to detect the movement of the putter. In addition, the golf ball is detected when the impact of the golf ball by the first golf ball sensor 3, the time the golf ball is moved for a predetermined distance by the second golf ball sensor (3).

Subsequently, the central processing unit 6 moves the putter's swing trajectory, swing speed, swing tempo, swing style, direction of golf ball, and progression of the golf ball based on the movement time of the putter and the time of the golf ball detected by each sensor. The distance is calculated and the value is transmitted to the display unit, and the display unit displays the received value. In addition, the speaker 8 indicates whether the golfer's swing is normal or abnormal. On the other hand, when the golfer inputs the golf ball in advance, the central processing unit 6 compares the actual travel distance with the input distance and sends a signal to the golfer through the speaker 8 as to whether or not the target distance is reached. To pass.

Therefore, golf can easily check the swing track, swing speed, swing tempo and swing style of the swing and the direction and distance of the golf ball and correct the swing by referring to the next swing. have.

The putting practice can be performed only with the putting correction and practice apparatus according to the first embodiment of the present invention described above. However, in some cases, a mat having a hole cup is attached to the putting correction and practice apparatus according to the present invention as in the actual green. You can practice putting your golf ball into the hole cup and correct your putting swing.

Next, a second embodiment of the putting correction and practice apparatus according to the present invention will be described. 7 is a perspective view showing a second embodiment of the putting correction and practice apparatus according to the present invention.

Two putter speed detection sensors 4e and 4f are provided in a line along the center line (X in FIG. 4) at the rear of the first golf ball detection sensor 3. The putter speed sensors 4e and 4f send the central processing unit the time when the putter is detected during the backswing or downswing of the putter. In the second embodiment, the putter detection sensors A to Putter detection sensors D '(4a to 4d') are used to grasp the trajectory of the putter and the like, and the speed of the putter is determined by the putter speed detection sensors 4e and 4f. In this case, the central processing unit 6 can calculate the putter speed calculation more quickly and accurately by the signals transmitted from the putter speed detecting sensors 4e and 4f. Here, the putter speed detection sensor has been described as two, but may be provided more than that, of course.

Next, a third embodiment of the putting correction and practice apparatus according to the present invention will be described. 8 is a perspective view showing a third embodiment of the putting correction and practice apparatus according to the present invention, Figure 9 is an exploded perspective view showing a golf ball recovery portion of FIG. As shown in the figure, the third embodiment of the putting correction and practice apparatus according to the present invention is a golf ball recovery unit 9 is installed at the end of the putting mat in the direction of the golf ball to recover the golf ball after putting It further includes.

The golf ball recovery unit 9 includes an inclined portion 91 inclined upward with respect to the putting mat 11, a curved portion 92 extending at an end portion of the inclined portion 91 in the golf ball traveling direction, and a curved portion 92. It is composed of an elastic member 93 installed on the surface.

The inclined portion 91 reduces the traveling speed of the impacted golf ball and allows the golf ball hit the curved portion 92 to be easily moved back to the initial setting direction. The curved portion 92 is installed at the end of the inclined portion 91 so that the golf ball no longer proceeds. The elastic member 93 strikes the curved portion 92 to move the golf ball changed in the initial setting direction to the initial setting direction more smoothly by elasticity.
