Description

  The present invention relates to a golf practice apparatus.

  In golf putting, it is indispensable to improve the putting technique to know how strong the ball should be hit with respect to the target distance to the hole or flag, that is, to develop a sense of distance.

The conventional practice device for cultivating the sense of distance of putting cultivates the sense of distance by a method such as calculating the distance that the ball actually rolls from the initial velocity of the ball and displaying it on a monitor screen etc. (Patent Literature) 1-4).
JP 7-116294 (published on May 9, 1995) JP 7-328172 (released on December 19, 1995) JP 2005-111195 (April 28, 2005) ACT 6-81567 (Released on November 22, 1994)

  Generally, a person performing putting aims at a target hole or flag, so that the target becomes harder to determine as the target becomes farther, and it becomes difficult to grasp the sense of distance.

  In addition, even a person who has practiced using the practice device of Patent Document 1 above, puts the target hole or flag at the target round during the actual round. And that person remembers the power of how many meters he displayed when he strikes at the time of practice, and uses it as a reference for grasping the sense of distance.

  Here, there are two problems in the practice using the practice device of Patent Document 1.

  One is that even a person who has practiced with the above-described practice device puts the target hole or flag at the target, so the difficulty that the target is harder to be determined as the target becomes farther is not solved.

  The other is that with the above practice method of adjusting the strength of putting according to the distance displayed on the monitor screen, it is difficult to learn a technique for performing stable putting.

  The putting motion is a pendulum motion. That is, the period of the pendulum movement is determined by the body shape of the person performing the putting and the length of the putter, and the putting is stabilized by performing the putting at a period suitable for each person.

  That is, in the practice device of the above-mentioned patent document 1, since the putting cycle suitable for each person cannot be worn, the putting is not stable.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to be able to practice in accordance with the putting cycle suitable for each person and to aim at a point closer to the original target. An object of the present invention is to provide a putting practice device that can more easily grasp a sense of distance to an original target by setting a target for the purpose.

  In order to solve the above-described problem, the putting practice device of the present invention is an intermediate reach position corresponding to a target distance to which the trainee tries to reach the ball, and after the trainee hits the ball, A pass sensor for detecting the passage of the ball at an intermediate position where the ball should pass when a time equal to k times the putting cycle (k is a natural number) has passed, and a trainee who has passed the ball detected by the pass sensor And a second notification means for notifying the practitioner of the putting cycle of the practitioner by engraving a predetermined pattern of rhythm.

  The first notifying means notifies the practitioner of the passage of the ball using light or sound, and the second notifying means notifies the practitioner of the putting cycle using light or sound.

  Here, the putting cycle is a cycle when shaking a putter determined by the body shape of the person performing the putting, the length of the putter to be used, and the like.

  Practice this putting cycle so that it is always constant regardless of the target distance. When the target distance is long, the swing width of the putter is increased. In this case, since the period is constant and the swing width is widened, the head speed of the putter is increased, and as a result, the distance to the point where the ball reaches is increased. Conversely, when the target distance is close, the swing width is narrowed. In this case, since the period is constant and the swing width is narrowed, the head speed of the putter is slowed, and as a result, the distance to the point where the ball reaches is shortened. Based on the above principle, the distance can be adjusted while putting in a constant cycle.

  In addition, as described above, the putting cycle is determined by the body shape of the person performing the putting, the putter to be used, and the like, so there are individual differences. Therefore, the putting cycle suitable for each person may be determined by finding a cycle that feels easy to swing by shaking the putter with various swing widths.

  In addition, the natural number k can be any number such as 1, 2, 3,..., But as the value of k increases, the distance from the practitioner to the passing sensor increases, making it difficult to aim. The value of k is preferably 1.

  According to the above configuration, the practitioner can recognize his / her putting cycle by the second notification means, and performs putting in accordance with the putting cycle.

  Here, the passing sensor is installed at an intermediate reaching position where the ball should pass when a time equal to k times (k is a natural number) has passed.

  That is, if the practitioner can perform the putting so as to pass through the passage sensor when a time equal to k times (k is a natural number) of his / her putting cycle has elapsed, The target distance will be reached.

  Therefore, the practitioner hits the ball in accordance with the rhythm notified by the second notification means, and after the ball is hit, the k-th rhythm is notified, and at the same time, the goal is for the ball to pass the passage sensor. Practice. The moment when the ball passes the passage sensor is notified to the practitioner by the first notification means.

  In this case, the position at which the practitioner aims is not the target distance but the passage sensor.

  In other words, the practitioner who uses the above putting practice device develops a sense of distance that makes the ball reach the target distance by aiming and putting the passing sensor located closer to the practitioner than the target distance. Can do. Since the aiming position is closer, it becomes easier to grasp the sense of distance to the target distance than when putting the target distance and aiming. The practitioner who uses the above putting practice device can practice according to his / her putting cycle, so that he / she can wear the putting cycle that suits him / her, which leads to stable putting. .

  Further, when the practitioner performs putting during the actual round, he or she imagines that there is a passing sensor on the putting line, and puts the aim at the passing sensor on the image and performs the putting. In other words, the sense of distance cultivated through repeated practice can be utilized as it is even during the actual round.

  In the putting device, the second informing means is portable to a practitioner, and a signal relating to the passage of the ball transmitted from the first informing means and a rhythm of a constant pattern engraved by the second informing means. It is preferable to inform the practitioner as information.

  By making the second notification means portable, it is possible to reduce the size. Also, the audio information emitted by the first and second notification means is not leaked to the surroundings by listening with the earphone or the like. Therefore, when the putting practice device of the present invention is used in a golf practice field or the like, it does not interfere with the practice of neighboring trainers by the notification sound emitted by the first and second notification means, and is used at home. In some cases, you can practice quietly.

Further, the putting practice device comprises a sensor passage time measuring means for measuring a sensor passage time required from when the trainee hits the ball until the ball passes the passage sensor,
And third informing means for informing the practitioner of a difference between the sensor passing time measured by the sensor passing time measuring means and a time equal to k times (k is a natural number) of the practitioner's putting period. It is preferable.

  According to the above configuration, the practitioner does not need to hit the ball simultaneously with the rhythm sound, and can practice by hitting the ball at his / her favorite timing. In this case, since the difference between the sensor passage time and the time equal to k times (k is a natural number) of the practitioner's putting period is notified by the third notification means, the practitioner is able to adjust the strength of the putting performed by himself / herself. Can be properly grasped and adjusted. Therefore, the practitioner can perform effective practice.

Further, the putting practice device of the present invention includes a passage sensor that detects the passage of the ball hit by the trainee, first notification means that informs the trainee of the passage of the ball detected by the passage sensor,
It is characterized by comprising fourth informing means for informing the practitioner of the ideal passing time that the ball should pass through the passage sensor, corresponding to the target distance that the practitioner is trying to reach the ball.

  According to the above configuration, the practitioner can know the ideal passage time by the fourth knowledge means, and can know the actual passage time by the first notification means. If the ball can be hit so that the ideal passing time and the time actually passing through the passing sensor coincide with each other, the ball can reach the target distance.

  Therefore, the practitioner can practice practicing distance sensation by aiming at a passing sensor installed at an arbitrary position on the putting line.

  As described above, the putting practice device of the present invention is an intermediate reach position corresponding to the target distance that the trainee is to reach the ball, and after the trainee hits the ball, the trainer's putting cycle When a time equal to k times (k is a natural number) has elapsed, a passing sensor that detects the passing of the ball at an intermediate position where the ball should pass, and the trainer is notified of the passing of the ball detected by the passing sensor. It is characterized by comprising first informing means and second informing means for informing the practitioner of the putting cycle of the practitioner by engraving a fixed pattern rhythm.

  According to the above configuration, the practitioner can perform the putting according to the putting cycle that suits him / herself, and while aiming at the passing sensor located closer to the practitioner than the target distance, Can develop a sense of distance.

  That is, the practice device has an effect that the user can acquire a putting cycle suitable for himself and can easily develop a sense of distance.

  Further, as described above, the putting practice device of the present invention includes a passage sensor that detects the passage of the ball hit by the trainee, and a first notification unit that notifies the trainee of the passage of the ball detected by the passage sensor. And a fourth informing means for informing the trainee of the ideal passing time that the ball should pass through the passage sensor, corresponding to the target distance to which the trainee tries to reach the ball. .

  According to the above configuration, the practitioner can know the ideal passage time by the fourth notification means, and can know the actual passage time by the first notification means. If the ball can be hit so that the ideal passing time and the actual passing time match, the ball can reach the target distance.

  Therefore, the practitioner who uses the putting practice device of the present invention performs the putting by aiming at the passage sensor that is closer to the practitioner than the target distance, and therefore, when performing the putting by aiming at the target distance. Compared to this, it is possible to more easily grasp the sense of distance to the target distance. The position where the passage sensor is installed may be an arbitrary position on the putting line.

[Embodiment 1]
As shown in FIG. 1, the putting practice device according to an embodiment of the present invention includes a crossover-type member 2 and a rhythm generating device (second notification means) 3.

  The overpass member 2 includes a passage sensor (passage sensor) 5, a passage signal transmission unit 6, and a light emitter (first notification means) 7.

  The rhythm generation device 3 includes a rhythm cycle input unit 8 and an earphone 9, and includes a not-shown passing signal reception unit and a rhythm sound generation unit.

  The crossover-type member 2 is installed at a position where the ball 1 should pass when a time equal to the practitioner's putting period has elapsed since the practitioner hit the ball 1, that is, an intermediate reach position.

  In the present embodiment, the intermediate reaching position is a position where the ball 1 should pass when a time equal to the practitioner's putting period has elapsed (when k = 1 in claim 1). The position where the ball 1 should pass when the time of an arbitrary integer multiple such as twice or three times the practitioner's putting period has elapsed can be set as the intermediate reaching position.

  The intermediate reaching position is determined by the practitioner's putting cycle, the target distance, and the coefficient of friction between the ball 1 and the surface on which the ball 1 rolls.

  Therefore, the practitioner puts the passing point of the ball 1 after the time equal to the practitioner's putting period when putting on the green to be practiced and putting suitable for the target distance. It is determined.

  For example, when the putting cycle is 1.0 second, the target distance is 20 m, and the intermediate reach position is 5.8 m in a certain green, the practitioner installs the crossover type member 2 5.8 m ahead. Practice. Below, the case where practice is performed on these conditions is demonstrated.

  The overpass type member 2 is configured such that when the ball 1 passes thereunder, the passage sensor 5 detects the passage of the ball 1. When the passage of the ball 1 is detected, the light emitter 7 is turned on, and at the same time, the passage signal transmitter 6 transmits a signal related to the passage of the ball 1 to the rhythm generator 3.

  When the practitioner inputs a putting cycle to the rhythm cycle input unit 8, the rhythm generator 3 sends an instruction to a rhythm sound generation unit (not shown) according to the input cycle to generate a rhythm sound of a certain pattern. is there. The passage signal receiver (not shown) of the rhythm generator 3 receives a signal related to the passage of the ball 1 transmitted by the passage signal transmitter 6. When the passing signal receiving unit receives a signal related to the passing of the ball 1, the passing signal receiving unit sends an instruction to the rhythm sound generating unit to generate a ball passing sound indicating the passing of the ball 1. The rhythm sound and the ball passing sound generated by the rhythm sound generation unit are notified to the practitioner via the earphone 9.

  The constant pattern rhythm sound may be any sound that allows the practitioner to recognize his / her putting cycle. The rhythm sound pattern may be, for example, a time interval that is equal to the practitioner's putting cycle, or a constant value such as 1/2, 1/3, or 1/4 times the practitioner's putting cycle. A time interval may be used. In addition, the rhythm sound pattern is a pattern that combines the rhythms of the predetermined time intervals to constitute one cycle of the practitioner's putting, and the combined pattern is repeated to notify the practitioner's putting cycle. There may be. Specifically, if the practitioner's putting cycle is 1.0 second, a quarter cycle, that is, a quarter-second interval rhythm is twice, and a 1/2 cycle, that is, a 1/2 second interval rhythm. Rhythm that is combined once.

  In the present embodiment, a case will be described in which a rhythm sound having a time interval equal to a practitioner's putting cycle is generated.

  With the above configuration, the practitioner using the putting practice device of the present embodiment hits the ball 1 in the direction of arrow A in FIG. After a time equal to the period has elapsed, that is, after the ball 1 is hit, practice is performed so that the ball 1 passes under the overpass member 2 at the same time as the first rhythm sound is generated.

  The practitioner can know the timing of his putting and the timing at which the ball 1 should pass under the overpass member 2 by the rhythm sound heard from the earphone 9, and the ball 1 actually moves over the overpass member 2. The moment of passing can be recognized by the light emitted from the light emitter 7 or the ball passing sound notified by the rhythm sound generator 3.

  Therefore, the practitioner can acquire a putting cycle suitable for him / her by performing putting in accordance with his / her putting cycle. Further, it is possible to develop a sense of distance to the target distance by aiming at the overpass member 2 that is closer to the practitioner than the target distance and is therefore easier to aim than the target distance.

[Functional Description of Putting Practice Apparatus of Embodiment 1]
In the above putting practice device, it is possible to practice wearing a sense of distance of various distances such as 10 m, 15 m, and 20 m. Here, a case of practicing 20 m putting will be described. Further, the putting period suitable for the practitioner varies depending on the individual as described above, but here, it is assumed that the putting period suitable for the practitioner is 1.0 second.

  As described above, in this embodiment, when the target distance is 20 m and the putting cycle is 1.0 second, it is assumed that the practice is performed in the green where the intermediate arrival position is 5.8 m. Accordingly, the practitioner installs the overpass member 2 at a position 5.8 m from the practitioner on the putting line.

  Next, the practitioner inputs 1.0 second which is a putting cycle suitable for the practitioner to the rhythm cycle input unit 8. The rhythm sound generator generates a rhythm sound at intervals of 1.0 seconds in response to the input of 1.0 seconds to the rhythm cycle input unit 8. The rhythm sound is notified to the practitioner via the earphone 9.

  The practitioner hits the ball 1 in accordance with the rhythm sound that can be heard from the earphone 9. The position at which the practitioner aims at hitting the ball 1 is the overpass member 2. The practitioner hits the ball 1 so that the ball 1 passes under the crossover-type member 2 at the same time as the rhythm sound following the rhythm sound generated when the ball 1 is hit. When the ball 1 passes under the overpass member 2, the passage sensor 5 detects the passage of the ball 1.

  When the passage sensor 5 detects the passage of the ball 1, the light emitter 7 is turned on. The practitioner can recognize the moment when the ball 1 passes by the lighting of the light emitter 7.

  Further, when the passage sensor 5 detects the passage of the ball 1, it sends an instruction to the passage signal transmission unit 6 to cause the rhythm generator 3 to transmit a signal related to the passage of the ball 1. When the passage signal receiver of the rhythm generator 3 receives a signal related to the passage of the ball 1, the passage signal receiver sends an instruction to the rhythm sound generator to generate a ball passage sound. The practitioner can hear the ball passing sound via the earphone 9.

  That is, the practitioner can recognize the moment that the ball 1 has passed by the visual information obtained by the lighting of the light-emitting body 7, and the moment that the ball 1 has passed under the overpass member 2 also by the audio information that can be heard from the earphone 9. Can be recognized.

  Therefore, the practitioner strikes the ball 1 in time with the rhythm sound, and at the same time that the next rhythm sound is heard, the light emitter 7 is turned on, or the practice is performed to hear the ball passing sound from the earphone 9. become.

  Further, when it is desired to practice while changing the target distance, the intermediate arrival position may be changed, and the sense of distance of various distances can be cultivated by installing the overpass member 2 at a position corresponding to the target distance. For example, when the target distance is 15 m, the intermediate reach position is about 5.0 m, and when the target distance is 10 m, the intermediate reach position is about 4.0 m. These intermediate arrival positions are merely examples, and the intermediate arrival positions change depending on the state of green or the like where putting is performed.

  Therefore, the practitioner can learn the distance from the practitioner to the crossover type member 2 according to the target distance, and can acquire a sense of distance to the target distance by wearing his own putting cycle.

  In addition, when the above putting practice device is used, it is possible to perform repeated practice in which putting is performed continuously in accordance with the rhythm. The practitioner can acquire a sense of distance to the target distance while acquiring a putting cycle that suits him / her by performing repeated exercises.

  In the above putting practice device, the position where the trainee aims is not the target distance but the crossover type member 2. Therefore, the practitioner puts the target closer to the practitioner than the target distance, so it is easier to grasp the sense of distance to the target distance than when aiming at the target distance and putting. can do.

  Also, when the practitioner performs putting during the actual round, imagine that there is a crossover type member 2 at a position corresponding to the target distance on the putting line, and aim at the crossover type member 2 on the image Putting. In other words, imagine that there is a crossover type member 2 at the intermediate reach position on the putting line, hit the ball with your own putting cycle that you learned in the above practice, and image 1.0 seconds after hitting the ball Putting is performed with the goal of passing through the overpass member 2 above. In other words, the sense of distance cultivated through repeated practice can be utilized as it is during the actual round.

[Explanation of modification]
In the practice using the rhythm generator 3 as described above, it is necessary to hit the ball 1 in accordance with the rhythm. However, there may be a case where the practitioner finds it difficult to hit the ball 1 in time with the rhythm.

  In such a case, it is preferable to use the ball start sensor 12 and the time difference indicator (sensor passage time measuring means) 13 in addition to the above configuration.

  The time difference indicator 13 displays a putting period input unit 14 for inputting a practicing person's putting period, and a difference between the time when the ball 1 has passed through the passage sensor 5 and the time equal to the practicing person's putting period. And a time difference display unit (third notification means) 15.

  The ball start sensor 12 detects the moment when the ball 1 starts to move when the practitioner hits the ball 1. When the ball start sensor 12 detects the start of the ball 1, the ball start sensor 12 transmits a signal related to the start of the ball 1 to the time difference indicator 13.

  The time difference indicator 13 receives a signal related to the start of the ball 1 transmitted from the ball start sensor 12 and a signal related to the passage of the ball 1 transmitted from the crossover member 2, and after the trainee hits the ball 1, The time required for 1 to pass under the overpass member 2, that is, the sensor passing time is measured. The time difference indicator 13 calculates the difference between the practitioner's putting period and the sensor passage time, and displays the calculation result.

  That is, when the practitioner inputs his / her putting cycle in the putting cycle input unit 14 in advance, the time difference indicator 13 indicates that the sensor passing time is equal to the time equal to the practitioner's putting cycle. The difference is calculated and the calculation result is displayed on the time difference display unit 15.

  For example, when the sensor passage time is 0.5 seconds longer than the time equal to the putting cycle, “+0.5 seconds” is displayed on the time difference display unit 15. The practitioner can recognize that he / she has hit too hard by looking at this display.

  In addition, although the structure which displays the difference of sensor passage time and the time equal to a putting period was shown above, it can also be set as the structure which displays sensor passage time. Since the practitioner can grasp the strength of the putting based on the magnitude relationship between the sensor passing time and his / her putting cycle, the effect similar to the above can be obtained. For example, if the putting cycle is 1.0 second, it can be seen that if the sensor passage time is 1.0 second, the putting suitable for the target distance can be performed. On the other hand, when the sensor passing time is displayed as 1.2 seconds, it can be seen that the time for passing through the intermediate arrival position was slow, which means that the time was too weak.

  When the sensor passing time is configured to be displayed, the practitioner does not need to input the putting cycle to the time measuring device 13. Since the time difference indicator 13 does not need to calculate the difference between the sensor passage time and the time equal to the putting period, the time difference indicator 13 can be simplified.

  If the above function is used, the practitioner does not need to hit the ball 1 in time with the rhythm, and can hit the ball 1 at his / her favorite timing. The practitioner can know whether the difference between the sensor passage time displayed on the time difference display unit 15 and the time equal to the practitioner's putting cycle is positive or negative. Therefore, when the ball 1 is hit next time, the strength of putting can be adjusted.

  In addition, after getting used to the distance sensation in the above practice, it is possible to shift to the repetitive practice according to the rhythm sound described above and to fix the distance sensation worn.

[Embodiment 2]

  The condition input panel 4 receives an input of a target distance that the practitioner wants to practice and a distance from the practitioner to the crossover type member 2 and outputs an ideal passing time.

  The condition input unit 10 receives input of the target distance and the distance from the practitioner to the overpass member 2 and sends the input condition to the calculation unit. The calculation unit calculates an ideal passage time from the input conditions by the following method, and sends the calculated result to the ideal time display unit 11 to display the ideal passage time.

  Here, the ideal transit time refers to the time that the ball 1 hit by the practitioner should pass through the overpass member 2 corresponding to the target distance.

  If the target distance and the distance from the trainee to the crossover type member 2 are determined, the ideal passing time is determined. That is, when the practitioner inputs the target distance and the distance to the crossover type member 2 to the condition input unit 10, the ideal passing time is calculated.

  The ideal passing time is calculated by the calculation unit solving the equation of motion established based on the target distance and the distance between the practitioner and the overpass member 2. The ideal transit time can also be calculated as follows.

  That is, a storage unit is provided in the condition input panel 4, and the distance between the practitioner and the crossover type member 2, the target distance, and the ideal transit time are calculated in advance in association with each other. A table associated with values may be stored in the storage unit. FIG. 2 shows an example of the table. When the practitioner inputs the distance between the practitioner and the overpass member 2 and the target distance to the condition input unit 10, the calculation unit determines an ideal passing time using the table shown in FIG.

[Functional Description of Putting Practice Device of Embodiment 2]
First, the practitioner installs the crossover type member 2 at an arbitrary position on his / her putting line. Then, the target distance and the distance from the practitioner to the overpass member 2 are input to the condition input unit 10 of the condition input panel 4.
