Description

  The present invention relates to a golf club swing practice system, and particularly has the following objects. When practicing golf club swings, you must satisfy both the requirements of measuring the speed of the swing and being able to concentrate on the swing. When concentrated on the swing, the standing position often moves while the swing is repeated, and at least the swing of the shoulder width inevitably occurs. Therefore, it is an object of the present invention to be able to measure stably even when such a deviation of the standing position occurs.

It can also be used at golf driving ranges. That is, the front installation is impossible and the side installation is not impossible, but difficulty may occur depending on the facilities of the driving range. In addition to knowing the speed of the measurement result as an absolute value, you can know the relative evaluation of how much the swing was, for example, based on your best shot swing.

  In addition to grasping with numbers, you can grasp the state of your swing without the need to read numbers such as color display. You can grasp the relative speed and guide the timing of swinging the golf club to practice the feeling of full swing or half swing, and the relative degree or color of the degree of swing. That can be confirmed.

  Even when performing various measurements as described above, if you are concerned about whether the microwave to be irradiated in the measurement has arrived or is in the measurement range, you cannot settle down and practice. Therefore, it is desirable to be able to easily check whether the current setting is in the correct state.

  Patent Document 1 is a swing training device for a ball tool. This apparatus is provided with a laser beam reflecting portion on a ball impact surface of a golf club, and when the laser beam is emitted from the front and the swing is performed, The head speed of the golf club can be calculated by processing the laser beam reflected and returned without actually hitting the ball. It can be measured with a golf club that you always use. However, when actually hitting the ball, the speed cannot be measured unless a transparent special ball is used. In order to prevent the golf ball from hitting the device, it has been proposed that only the laser is delivered by an optical fiber. However, how to apply the laser beam emitted from the optical fiber to the golf club The conditions that cannot be used unless they are naturally solved are not described, such as whether to set the trajectory or the directivity. On the other hand, a system that measures the speed by embedding a sensor under the artificial turf and the golf club head crosses over the sensor is currently used, but the tee position is related to the sensor position. -It is a large-scale measuring device that is used only for hitting the golf ball and difficult for the user to carry to the driving range.

  Japanese Laid-Open Patent Publication No. 54-104942

  The above-described conventional swing practice device (system) is a method that depends on the specularity of the golf club hitting side, so of course, a device that outputs laser light is installed on the side where the ball jumps out. The device described in Patent Document 1 is highly likely to be hit by a ball, and the user is also highly likely to be in danger by rebounding in an unpredictable direction. Moreover, when there is no installation space ahead like a driving range, installation itself is difficult. On the other hand, although not illustrated, there is also a device that measures the golf club head speed by installing a practice device on the side of the golf club track during swing practice, but the user's standing position is changed by one step. The orbit of a golf club is quickly shifted to about a dozen centimeters. This misalignment can cause an accident where the golf club hits the practice device. Furthermore, the type in which the practice device is placed on the side and the head speed is measured measures the difference in passing time of the head of the golf club measured between two points. There was a problem that the measurement was practically impossible. As described above, the fact that there is a person who cannot use the product due to the characteristics of the product has a problem that the user must be alerted when purchasing the product.

  The measurement using the reflection of the laser beam as shown in Patent Document 1 measures the head speed in a very limited range as long as the patent specification is read. In addition, as for the type that measures at a lateral position with respect to the track of the golf club, as described above, when the track is shifted by several centimeters or tens of centimeters in the lateral direction, not only the measurement can be performed, but the golf club Various problems arise when the device is hit. Thus, by providing a speed measuring device, there is a face that obstructs the practice of golf swing, or if it is distracted by the practice of swing, it is not preferable as a practice device for improving . Therefore, it is required that the machine can be used without worrying about the position where the machine is installed.

  In the past, there was a strong tendency to use the head speed numerically to determine the user's ability, but it is not always enough to look at the absolute speed of the head speed. When using it to remember with your body, remember the head speed obtained during your best swing, multiply it by the required speed, and practice to approach that number. . The practice method that relies on the numerical value is not suitable for practice, and it is unlikely that a good result will be obtained.

  Conventionally, the numerical measurement results are not intuitively understood, but the rhythm of practice shots tends to be distorted by a series of operations for reading the numbers. In some cases, it is not possible to concentrate on practice. An object of the present invention is to provide a golf club swing practice system that solves many of the problems described above.

  The invention according to claim 1 determines a hitting area of a user who performs a swing of a golf club, determines a hitting direction from the hitting area, is opposite to the hitting direction and is outside the swing range of the golf club. A microwave transmission device is disposed, the microwave transmission device has directivity toward the hitting position, and the maximum speed of the golf club based on the difference in the frequency of the microwave generated when the microwave hits the golf club The memory means for storing the head speed measurement result after any swing as a reference speed, and the reference speed stored in the memory means for the measurement result of the head speed measured thereafter And a display means for displaying information obtained by the calculation means. It is characterized in the that the golf club swing training system to be.

  The invention according to claim 2 is characterized in that the directivity of the microwave transmitting device toward the hitting position is equal to or greater than the shoulder width of the user.

  According to a third aspect of the present invention, there is provided a display means for presetting a recognition color corresponding to the numerical value of the relative ratio and displaying a measurement result of the measured head speed as the recognition color.

  According to a fourth aspect of the present invention, there is provided a tempo generating device that notifies the timing of swinging the golf club at intervals of a plurality of notification signals.

  The invention described in claim 5 is characterized in that it has narrow directional light means that shows a range equivalent to the measurement range of the microwave transmission device by visible light.

  The effects of the invention defined in claim 1 are as follows. Being out of the swing range of the golf club has eliminated the concern of accidentally hitting the device with the golf club and causing a malfunction. Furthermore, even when an actual hit ball is measured by the method of measuring at the rear position, various obstacles caused by a high-speed flying ball hitting the apparatus are eliminated. This failure means that the device fails due to the impact of the ball, and the ball hits the device and flies in an unexpected direction. Also, make a full swing so that the head speed is the fastest. Data of the head speed at which this swing is measured is stored. It is possible to display as a ratio display (% display) how much the subsequent swing is swinging with respect to the stored speed. For example, you can practice half shots.

  The effect of the invention defined in claim 2 is as follows. In the first aspect of the present invention, the microwave is irradiated to the range of the shoulder width of the user with respect to the track of the golf club for the purpose of the microwave, and the irradiated microwave hits the golf club, and then has a Doppler effect. By monitoring the frequency of the microwave that bounces back and returns, even if the position of the golf swing is moved at least about the shoulder width, it does not exceed the measurement range, it is easy to install, and it is nervous relative to the place where it swings You can concentrate on playing so you don't have to.

  The effect of the invention defined in claim 3 is as follows. When the speed is almost the same as the reference speed, white is displayed when it exceeds 10%, red when it exceeds 20%, red when it exceeds 20%, blue when it is below 10%, blue when 20% Set the recognition color corresponding to the value of the relative ratio, such as blinking blue when it is less than, and blinking green at 50% half swing. As a result, you can concentrate on the swing and intuitively understand the head speed.

  The effect of the invention defined in claim 4 is as follows. A tempo generating device is provided which notifies the timing of swinging the golf club at intervals of a plurality of notification signals, and this tempo generating device is notified by sound, light, color or the like. For example, when the tempo is generated by sound, the sound generated by a buzzer or a speaker, for example, “beep”, “beep”, and “beep” can be reproduced. Corresponding to these three sounds, the user can perform “take back”, “top”, and “shot” together. It should be noted that the tempo generating device can be set to the color of the display means that can display the color, or the timing of light. Furthermore, it is possible to register the half tempo and the like, and finally the half shot timing can be remembered by the rhythm while finely adjusting the tempo.

  The effect of the invention defined in claim 5 is as follows. By providing the narrow directivity light means that shows the range equivalent to the measurement range of the microwave transmission device with visible light, the place where the user is about to take a shot is within the measurement range. It can be confirmed visually. The visible light can express a plurality of colors, so that it can be used as display means for displaying the measurement result of the head speed as the recognition color. It is possible to substitute by blinking the narrow directional light means.

  It is the perspective view which provided the viewpoint on the upper part which shows the mode of the whole swing practice system of the golf club in this invention.   It is a side perspective view which provided the viewpoint to the side on the same conditions as FIG.   It is a block diagram of the electronic circuit which a swing training apparatus contains.   It is the perspective view, top view, and side view of a swing practice apparatus.

BEST MODE FOR CARRYING OUT THE INVENTION

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are conceptual diagrams of an embodiment according to the present invention. In the figure, (1) is a user, (2) is a golf club, (3) is a golf ball, (4) is a swing practice device that forms the core of this golf club's swing practice system, and (5) is a user. This indicates that both right-handed and left-handed are possible, and is located away from the golf club (2) track and on the opposite side of the golf ball (3). Yes.

  In this figure, the swing practice device (4) is separated so that the structure can be seen from the center, with the upper half on the left and the lower half on the right, so that the practice system can be conceptually understood. (4a) is a microwave transmitting / receiving unit, (4b) is a microwave transmitted from the microwave transmitting / receiving unit, (4c) is a liquid crystal display device, and (4d) is provided in parallel with the microwave transmitting / receiving unit. The narrow directional light means (4d) of the lamp device illuminates an area that is the same as or slightly narrower than the microwave (4b). The narrow directional light means (4d) is configured such that the right side (4dR) is red and the left side (4dL) is blue in the drawing, and the microwave (4b) is within the range illuminated by the visible light narrow directional light means. ) Is adjusted to match the range where the Note that the transmission directivity and intensity of the microwave (4b) are selected so that the microwave (4b) has a measurement region as wide as the shoulder width in the user (1).

  FIG. 1 is an overall view of a golf club swing practice system, in which the hitting direction is drawn as the upper position. The service area (6) is a preferred area for measuring the head speed when the golf club swings. In this service area (6), the swing practice device (4) is installed at a position separated by a certain distance or more backward with respect to the hitting direction, and the microwave (4b) emitted from the device has a certain strength. Shows the range. Also, considering the convenience of the user (1), by turning on the narrow directional light means (4d) as desired, the microwaves that cannot be confirmed with the eyes can be visualized to know the usage situation sensibly. It is possible. The light of this narrow directional light means (4d) is (4d) in the figure, and the same or slightly smaller area than the actual service area is visualized by the narrow directional light means (4d). Is preferred. The lighting timing of the narrow directional light means (4d) can be a circuit configuration for lighting as follows.

  First, it blinks for several seconds immediately after turning on the main power of the swing practice device (4).

  Second, it flashes for a few seconds when high-speed swing is not measured for a preset time in the microwave (4b) of the swing practice device (4).

  Third, it blinks at the timing when the measurement result after swinging. Preferably, when the measurement result exceeds the reference level, red is strongly emitted, and when the measurement result is below the reference level, blue is strongly emitted.

  Part 4: When generating a tempo by using a sound to take swing timing, a device is provided that can reproduce the sound generated by a buzzer or speaker, for example, “beep”, “beep” and “beep”. Corresponding to these three sounds, the user can perform “take bag”, “top”, and “shot” together, and the tempo generation can be performed by display means that can display the color. It can be the color or the timing of the light of this narrow directional light means.

  FIG. 2 shows a state of observing from the side, and the microwave (4b) has a certain limit even in the height direction, but the narrow directional light means (in the range which does not exceed or exceeds the range). It is illuminated by the light emitted from 4d), for example, it can be confirmed that the head of the golf club (3) is illuminated by this light source. The figure also shows that the swing practice device (4) is in a positional relationship where it can hardly be hit by the swing of the golf club (3).

  The inside of the swing training apparatus (4) performing the above operation will be described with reference to the block diagram of FIG. In the figure, (4e) is a microwave output circuit, (4f) is a microwave transmission / reception transducer, (4g) is a microwave reception circuit, (4h) is a microwave analysis circuit, (4i) is a content circuit, and (4j) ) Is a liquid crystal display device.

  First, the microwave output circuit (4e) includes a microwave transmission unit and a microwave amplification unit, where the microwave electric signal is amplified to a certain level, and is then transferred to the microwave transmission / reception transducer (4f). The microwave transmission / reception transducer (4f) emits the received microwave to free space and receives the reflected microwave. Thereafter, the received microwave electrical signal is analyzed by the microwave analysis circuit (4h). In the analysis, the difference between the frequency transmitted by the microwave output circuit (4e) and the received frequency is monitored, and the difference in frequency due to the Doppler effect is detected and analyzed.

  The analyzed result is received by the content circuit (4i). Thereafter, in the content circuit (4i), the frequency fluctuated by the Doppler effect is converted into speed as it is, digitized, transferred to the liquid crystal display device (4j), and speed display is performed. The content circuit (4i) can switch the content in conjunction with the button of the selector (9) shown in FIGS.

  The selector (9) has the following configuration.

  The first is a button for changing the top and bottom of the liquid crystal display device (4j). This is a button for switching the top and bottom of the display as desired by the user.

  The second is a reference speed setting button. This is because when the golf club swing is measured several times and the swing speed to be recorded is obtained, pressing this button causes the electronic storage medium of the circuit in the content circuit (4i) to Numerical data of the preferred swing speed is recorded. This button can be recorded again and again, for example, up to three can be recorded, and data at three speeds, for example, full swing, can be recorded. Next, the normal swing speed is recorded. Furthermore, it can be used for recording a speed considered to be a half swing.

  The third is a mode switching button. Four types of switching are prepared, and pattern A which is one of them can be set to a mode in which the maximum speed of the golf club (3) is displayed numerically after swinging the golf club (3). As an example of the measurement result, “38.8 m / sec” can be displayed numerically on the liquid crystal display device (4j). Next, pattern B is a mode for comparing and displaying the speed data stored by the second reference speed setting button, for example, stored as a full swing. In the comparison display, in addition to the numerical expression displayed as a percentage with respect to the reference speed, the following color display can be used to change almost the entire color of the liquid crystal display device (4j). By changing the overall color, you can know the measurement results just from a distance.

  The color is set as follows.

  Red: When the result measured by swinging immediately before is 180% or more calculated from the selected reference speed.

  Pink: When the result measured by swinging immediately before is 120% or more and less than 180% or more calculated from the selected reference speed.

  Colorless: When the result measured by swinging immediately before is 90% to less than 120% calculated from the selected reference speed.

  Light blue: When the result measured by swinging immediately before is 60% or more and less than 90% or more calculated from the selected reference speed.

  Blue: When the result measured by swinging immediately before is calculated from the selected reference speed and is less than 60%.

  The color display can be narrow directional light means (4d) in addition to the liquid crystal display device (4j). In order to perform multicolor expression as described above, the narrow directivity light means (4d) needs to have, for example, three primary colors. However, if only the expression of red and blue is used, the embodiment shown in FIG. 1 can be used.

  Furthermore, the pattern C applies a buzzer signal to the speaker (4k) when the swing timing is expressed by sound as described above. Furthermore, by applying a voltage to the liquid crystal display device (4j) and the narrow directional light means (4d), it is possible to reproduce “beep (blue)”, “beep (blue)”, and “beep (red)”. An apparatus is provided, and the user can perform “take bag”, “top”, and “shot” in accordance with these three triggers. In a public driving range, it is also possible to provide a manner mode in which sound is turned off and guidance is provided only with light.

  Finally, pattern D is the same as pattern C, but is a mode set for guiding the timing so that the swing is 50% with respect to pattern C for half swing.
