Electronic putting practice device {AN ELECTRONIC PUTTING TRAINING APPARATUS}

The present invention relates to a putting practice apparatus, and in particular, by attaching a sensor and a light emitting element to enable the tempo control of the putt during putting practice, and can significantly improve the putting ability of the golfer by maintaining the putter during the impact at a square state It relates to an electronic putting practice device.

In recent years, as the economy develops and people's income levels improve, the golf population has increased significantly. The increase in the golf population is increasing with the establishment of the golf course, and has been reborn as a popular sport gradually, stigmatizing the past aristocratic sports. Moreover, golf is becoming more and more popular due to the success of Korean professional golfers in the United States.

Golf has the advantage of not being intense compared to the amount of exercise, there is an advantage that everyone can enjoy casually, while the disadvantage is that it is very difficult to climb to a certain level. Therefore, it is common practice for beginners who are new to golf to learn basic skills through lessons at indoor golf ranges near their homes instead of going to the field for a period of time.

In general, indoor practice areas practice various swings that are the basis of golf. For example, wood, irons, and putters are the most basic golf clubs for golfing, and the practice ranges are practiced using these basic golf clubs. However, the wood and iron of the golf clubs as described above, because the length of the shot (shoot) is long, while a relatively large exercise field is required for accurate swing practice, the putter used to put the ball in the hole is a relatively small distance ( Because it is usually used in a few meters, it can be practiced in a relatively small driving range or even at home.

Therefore, as a means for the rapid acquisition of golf technology (particularly, putting technology), a putting exerciser capable of putting practice in a narrow space such as a home has been developed and spread. The putting exerciser is composed of a mat serving as a green of a golf course and a hole cup in which a ball is placed at an end of the mat. In other words, this putting exerciser is a part of the green of the golf course as an exerciser, and its purpose was to develop a simple putting sense. Therefore, it is impossible to acquire high-level techniques such as correcting wrong putting habits of a user or acquiring accurate impact.

The present invention has been made in view of the above, by attaching a sensor and a light emitting device to enable the tempo control of the putt during putting practice and can significantly improve the putting ability of the golfer by maintaining the putter during the impact square. An object of the present invention is to provide an electronic putting practice apparatus.

Another object of the present invention is to provide a portable electronic putting practice device that can be put to practice in putting the green in practice, simply portable.

In order to achieve the above object, the electronic putting practice apparatus according to the present invention is provided with a hole cup that is hole-in the golf ball at one end of the mat and the ball proceeds when putting, and is installed in the backswing area of the putter and flashing sequentially according to the set speed A plurality of light emitting devices to inform the golfer of the swing tempo of the putter, a plurality of sensors installed in the backswing area of the putter to sense the position of the putter when putting, and the light emitting device by applying a signal to the light emitting device to set the speed And a control device for detecting a square state of the putter on the basis of a signal input from the sensor.

The control device includes a speed setting unit for setting a blinking speed of the light emitting element indicating a swing tempo of the putter, a signal applying unit for applying a speed signal set by the speed setting unit to the light emitting element and blinking the light emitting element; A speed measuring unit measuring a swing speed of the putter based on a signal applied from an optical sensor, a speed comparing unit comparing the speed set by the speed setting unit with the measured speed and comparing whether the putting is performed at a set speed; A square recognition unit determining whether the impact of the putter and the golf ball is 90 degrees based on a signal input from the sensor, and between the sensor and the putter at each sensor position based on signals input from each of the plurality of sensors.

Hereinafter, with reference to the accompanying drawings will be described in detail the electronic putting practice apparatus according to the present invention.

1 is a view showing the electronic putting practice apparatus according to the present invention. As shown in the figure, the electronic putting practice apparatus 1 of the present invention comprises a base (not shown) on which an artificial mat 3 is formed and a side wall 2 formed at a predetermined height around the base. The mat (3) is to obtain the same effect as in the green (green) of the actual golf course is the portion where the golf ball 10 rolls when putting. At one end of the mat (3) is formed a hole cup (5) into which a golf ball enters when putting, and on the opposite end, a putting start line for placing the ball when putting is indicated. Typically the putting start line is not formed at the end of the putting mat (3). In other words, the putting start line is formed inward at a distance from the opposite end of the hole cup 5, which is for take back of the putter when putting.

As shown in the figure, in the present invention, a plurality of light emitting elements 7 are arranged on the upper surface of both side walls 2 of the rear end direction of the putting start line (that is, the backswing area of the putter extending in the opposite direction of the hole cup 5). It is. The light emitting device 7 may be any device that emits light as a signal is applied, but an LED (Light Emitted Device) that is inexpensive and simple to mount is preferable. The light emitting device 7 sequentially flashes from left to right or right to left at predetermined time intervals. The sequential blinking of the light emitting element 7 has a constant tempo, which corresponds to the swing tempo of the putter. In other words, when the golfer uses the putting practice apparatus, the blinking speed of the light emitting device 7 indicates a swing tempo of the desired putter, and the user has a flashing speed of the light emitting device 7 (strictly speaking from left to right or By swinging along the flashing speed from right to left, the desired swing tempo can be learned.

In addition, two optical sensors 9a and 9b are provided on the inner surface of the side wall 2 (the surface facing the putting mat) at regular intervals. The optical sensors 9a and 9b may be any optical sensors as long as they are provided with light emitting means and light receiving means. The photosensors 9a and 9b detect the position of the putter 12. In general, the accuracy of the putter is determined by the impact angle (ie, the impact angle) of the ball and the putter 12 and the trajectory of the putter 12. In order for the ball heated by the putter to accurately go in the direction desired by the golfer, when the golf ball 10 and the putter 12 collide with each other, the advancing direction of the golf ball and the impact surface of the putter 12 are exactly 90 degrees. Kinetic energy must be completely transmitted to the golf ball (10). This phenomenon is referred to as 'square', and the square depends on the angle of the golf ball 10 and the putter 12 and the swing trajectory of the putter 12. The two optical sensors 9a and 9b not only detect the angle of the impact surface of the putter 12 for impact construction but also detect the position of the putter so that the swing trajectory of the putter 12 can be detected. .

Although not shown in the drawing, a sensor for recognizing the hole-in of the golf ball 10 is mounted inside the hole cup 5.

In addition, although not shown in the drawing, the electronic putting practice apparatus of the present invention is connected to the light emitting device 7 and the light sensors 9a and 9b, and flashes the light emitting device 7 according to a set speed and the light sensor ( The control apparatus which detects the position of a putter by the signal input from 9a, 9b is provided. The control device may be installed inside the base of the putting practice apparatus in which the mat 3 is formed, or may be installed on the side wall. In addition, it may be manufactured separately from the base or side wall and connected through a connection means (for example, a connection jack) formed on the base or side wall.

Figure 2 shows the actual putting practice method using the electronic putting practice apparatus of the present invention. In the drawings, the light emitting device 7 and the light sensors 9a and 9b are displayed on one plane for convenience of description.

As shown in the figure, in the electronic putting practice apparatus 1 of the present invention, the light emitting device 7 installed along the backswing area of the putter 12, that is, the takeback area, is sequentially flashed so that the light is turned from one direction to the other. Proceeds at a constant speed in the direction. The traveling speed of the light represents the putting swing speed of the golfer who practice putting, and the blinking speed of the light emitting device 7 may be arbitrarily set by the golfer. Therefore, the golfer can arbitrarily set the swing tempo which he considers the most desirable.

The flashing of the light emitting element 7 proceeds not only in the putting direction but also in the opposite direction, that is, in the takeback direction of the putter. This is because the exact price of the golf ball during putting is not only influenced by the swing tempo in the putting direction, but also greatly depends on the tempo of the takeback. Therefore, the flashing speed of the light emitting element 7 can be set in both directions.

The optical sensors 9a and 9b detect the position of the putter 12 when putting. Although two photosensors 9a and 9b are provided in the figure, more photosensors may be provided. However, in order to measure the impact angles of the golf ball 10 and the putter 12 at the moment of impact, one of the optical sensors must be installed at the impact position of the golf ball 10 and the putter 12. As shown in the figure, the light emitted from the photosensors 9a, 9b is reflected at the side of the putter 12 and inputs back to the photosensors 9a, 9b. The photosensors 9a and 9b detect the position of the putter 12 by calculating the distance from the photosensors 9a and 9b to the putter 12 based on the time when the light is emitted and input again.

The optical sensor 9a provided at the impact position of the golf ball 10 and the putter 12 detects the impact angle of the golf ball 10 and the putter 12. In order for the golf ball 10 to proceed precisely toward the hole cup 5 at the moment of impact of the golf ball 10 and the putter 12, the collision angle between the golf ball 10 and the putter 12 is exactly 90 degrees, and thus the desired golf ball. The direction of travel and the direction of putting should be the same. If the impact angle between the golf ball 10 and the putter 12 does not reach 90 degrees, the impact surface of the putter 12 (commonly referred to as the face of the putter) is opened or closed. In this case, the golf ball 10 is to proceed in a different direction than the hole cup (5). Therefore, in order to know whether the impact is made correctly, it is necessary to detect whether the golf ball 10 and the putter 12 are at an angle of 90 degrees.

In the present invention, the photosensors 9a and 9b detect the angle between the face of the putter and the putting direction. In particular, the photosensor 9a detects the angle of the impact moment. 3 shows an angle detection method of the face and the putting direction. At this time, only the angle detection method of the impact moment which is particularly important at the time of putting is shown, but the angle detection by the other optical sensor 9b is also performed by the same method.

As shown in the drawing, the optical sensor 9a is positioned adjacent to the light emitting part 9a 'emitting light and the light emitting part 9a' and receives the light reflected from the putter 12. 9a ''). At this time, an unshown partition wall is positioned between the light emitting portion 9a 'and the light emitting portion 9a' 'so that the light emitted from the light emitting portion 9a' reaches the light receiving portion 9a '' to detect the light. Prevent deterioration of accuracy. As shown in the figure, the optical sensor 9a applied to the present invention is preferably an optical sensor 9a which functions to spread light emitted from the light emitting portion 9a 'at a predetermined angle.

Although not shown in the drawing, when the impact angle of the putter 12 is exactly 90 degrees, the side surface of the putter 12 will be 90 degrees to the direction incident from the light emitting portion 9a '. Therefore, the light reflected from the side of the putter 12 will be incident to the light receiving portion 9a '' at the same time.

On the other hand, as shown in FIG. 3A, when the impact angle of the putter 12 does not form 90 degrees, the side surface of the putter 12 does not form 90 degrees with incident light (90 degrees or more or less). Therefore, there is a distance difference from the left side and the right side of the putter 9a to the optical sensor 9a. Therefore, incident light reaching the left and right sides of the side of the putter 12 has a time difference. In addition, as shown in FIG. 3B, even when the light is reflected on the side of the putter 12, the light reaching the light receiving portion 9a ″ of the optical sensor will have a time difference as described above. In other words, there is a time difference between the light emitted from the light emitting portion 9a 'and reflected on the left and right sides of the side of the putter 12 and reaching the light receiving portion 9a' 'again, which is the left side of the side of the putter 12. This means that the distances from the right side to the optical sensor 9a do not coincide with each other, which means that the face surface of the putter 12 does not form 90 degrees with the putting direction.

In the control device of the present invention, as described above, it is determined whether the impact angle between the golf ball 10 and the putter 12 is 90 degrees by the time difference detected by the optical sensor 9a.

In addition, the optical sensors 9a and 9b may detect the swing speed of the putter 12. That is, since the light reflected from the side of the putter 12 is sequentially input to the two optical sensors 9a and 9b, the swing is caused by the difference in the sensing time of the putter 12 and the distance between the optical sensors 9a and 9b. The speed can be detected.

4 is a view showing a control device of the electronic putting practice device, the control device may be integrally formed on the base or sidewall of the putting practice device, may be formed separately and connected by a connecting means.

As shown in the figure, in the control apparatus, the flashing speed of the light emitting element 7 is set by the speed setting unit 22, and a signal for the speed set by the signal applying unit 20 is set to the light emitting element 7. The light emitting element 7 is blinked at a desired speed by being applied to. At this time, the flashing speed of the light emitting device 7 may be set by the golfer. In addition, the flashing speed of the light emitting element 7 may be set to a speed stored in the storage 44. Since the storage unit 44 stores a desired swing tempo, for example, a famous golf player's swing tempo, the golfer can practice putting by setting a desired swing tempo.

In addition, the storage unit 44 stores the swing tempo most suitable for the golfer using the putting practice apparatus. The swing tempo is obtained by synthesizing the case in which the golf ball is holed in the hole cup 5 by a sensor mounted inside the hole cup 5. The swing tempo is obtained by the golfer putting practice at the set swing tempo. It is a swing tempo with excellent putting performance. Therefore, the golfer can obtain the swing tempo that is most suitable for him by repetitive putting practice, and the desired result can be obtained by intensively practicing this swing tempo.

The signals sensed by the light sensors 9a and 9b are input by the speed measuring unit 24 to calculate the swing speed of the putter 24. The calculated swing speed is compared with the speed set by the speed setting section 22 by the speed comparing section 26, so that the two speeds do not match (that is, the flashing speed of the light emitting element does not match the actual swing speed). If it is determined that the swing tempo of the actual golfer is different from the swing tempo to be acquired, the warning unit 30 informs the swing abnormality of the putter 12 and simultaneously displays it on the display 32.

The signals sensed by the optical sensors 9a and 9b are input to the sensing recognition unit 36 through the input unit 34 to detect the position of the backswing (takeback) and the putter 12 during swing. In addition, the square recognition unit 38 determines whether the impact angle between the putter 12 and the golf ball 10 is 90 degrees based on the distance information of the putter 12 detected by the detection recognition unit 36 and the result is 90 degrees. If the putter 12 is recognized as being square and is not 90 degrees, it recognizes that the putter 12 is not squared and informs it through the warning unit 30.

On the other hand, with respect to the detected putter 12, what is important is not the absolute position of the putter 12, but the relative position at the place where the respective optical sensors 9a and 9b are installed. This relative position is detected by measuring the time at which the light emitted by the photosensors 9a, 9b is reflected by the putter 12 and is incident. The distance calculation unit 40 calculates the distance between the light sensors 9a and 9b and the putter 12 at the place where the light sensors 9a and 9b are installed on the basis of the time emitted and incident as described above.

The calculated distance is input to the track calculation unit 42. The trajectory calculation unit 42 calculates a swing trajectory of the putter 12 based on the input distance. When the distances measured by the optical sensors 9a and 9b are the same, the swing trajectory of the putter 12 is in a direction parallel to the putting direction toward the hole cup 5, and in other cases, the track has an angle with the putting direction. do. However, in order to make an accurate putting toward the hole cup 5, it is preferable that the swing direction of the putting direction and the putter 12 always coincide. Therefore, the track calculation unit 42 displays the swing trajectory of the putter 12 through the display 32 and at the same time the swing trajectory of the putter 12 does not coincide with the putting direction through the warning unit 30. Inform it. In addition, the putting trajectory of the golfer during the practice of mapping is stored in the storage unit 44 so that the golfer can determine how much his putting ability is improved.

In the drawings, reference numeral 46 denotes a power supply unit, and may be configured as a power supply unit through which an electric power is supplied through an external power supply unit, or may be configured as a battery built in a putting practice apparatus.

As described above, in the electronic putting practice apparatus of the present invention, it is possible to efficiently practice the swing tempo and accurate impact of putting by providing the light emitting element and the optical sensor. Since the putting practice device occupies only a small space in a room such as a house, it is possible to practice regardless of time and place.

In addition, the present invention can also be produced in a portable manner. In the case of the portable electronic putting practice device, the putting practice can be performed directly on the turf of the golf course rather than the putting practice on the artificially made mat, so that the putting practice can be performed more efficiently. In addition, the portable electronic putting practice apparatus may be used in a conventional putting practice apparatus.

5 is a portable electronic putting practice apparatus according to the present invention. As shown in the figure, the portable putting practice device 50 is composed of only a part of the electronic putting practice device shown in FIG. That is, in the electronic putting practice apparatus shown in FIG. 1, the light emitting device 7 and the light sensors 9a and 9b are provided with only side walls. Although the portable putting practice device 50 has a very simple configuration, the effect is very large. The putting on the artificial mat is very different from the green of the golf course, so it is difficult to achieve the desired result by putting only on the artificial mat. Therefore, it is necessary to practice in the practice green of the golf course as in practice, by using the portable electronic putting practice device 50 can obtain a great effect. In addition, since the portable electronic putting practice device 50 can be applied to a conventional putting practice device (usable by simply placing it on a conventional putting practice device), more efficient putting practice can be performed at a lower cost. do.

The portable electronic putting practice device 50 basically operates in the same manner as the putting practice device shown in FIG. 1. In the case of putting practice using the portable electronic putting practice apparatus 50, the portable electronic putting practice apparatus 50 is actually placed on the green and the golf ball is extended from the optical sensor 9a installed at the impact position. Just put it in and putt.

Although the portable electronic putting practice apparatus 50 is formed in the shape of a rod in the figure, the portable electronic putting practice apparatus 50 of the present invention is not limited to the shape thereof. For example, any material and shape may be produced by including only the basic concept of the present invention, such as forming the putting practice apparatus with a collapsible material to improve portability.

In addition, although not shown in the figure, the portable electronic putting practice device 50 includes a control device as shown in FIG. However, in view of improving portability, the control apparatus is manufactured separately from the electronic putting practice apparatus, and in practice, the objective of the present invention is merely achieved by electrically connecting the putting practice apparatus 50 and the control apparatus. You will be able to achieve wonderfully.

In the above description and drawings, the number and location of the light emitting devices and the optical sensors are limited. However, the scope of the present invention is not determined by the number and position of the light emitting device and the optical sensor as described above. If the plurality of light emitting elements and optical sensors are more than one, it is possible to install any number, and if the golfer can check the swing tempo and the position of the putter, it may be installed at any position. Such various applications to the present invention can be invented by anyone who works in the technical field to which the present invention pertains using the basic concept of the present invention, and it is obvious that such an application falls within the scope of the present invention.

As described above, in the present invention, since the light emitting device for notifying the swing tempo is installed in the putting practice apparatus, the golfer can accurately practice according to the swing tempo. The swing tempo can be set to the swing tempo of the famous professional golfer as well as the swing tempo that is most suitable for the golfer, as well as any tempo, more efficient putting practice can be performed. By measuring the speed of the golfer's direct swing and comparing it with the set tempo, the golfer is alerted to the golfer so that the golfer can always practice putting on with alertness.

In addition, since the optical sensor can know the square state of the putter during the putting practice, it reminds the golfer of the correct putting sense.

In the case of using the portable electronic putting practice device, the putting practice can be carried out directly on the green to enable the same putting practice as before. Allow them to raise their grades.
