Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a golf practice device set comprising a golf practice device attached to a golf club head and a golf mat provided with a light emitting element or a permanent magnet. .

(Prior Art) Various types of practice equipment have been provided for the purpose of learning golf skills.

However, most of these methods are aimed at correcting and stabilizing the swing form through repeated practice, or are generally done by swinging so that the speed of the club head reaches its maximum at the moment of impact or after impact. There was no numerical display or signal display to confirm whether the fish were in the water or not. Therefore, there is no guideline for determining whether or not the player has increased the flight distance of the ball and learned an accurate swing, making it impossible to confirm the results of practice.

(Means for Solving the Problem) When swinging a golf club, the present invention provides a method for increasing the flight distance of a hit ball and achieving accuracy toward the target when the speed of the club head changes at the moment of impact or at the moment of impact. Focusing on the fact that it is desirable to reach the maximum later, we incorporated WIi% into the club head and displayed the relationship between the maximum head speed and the timing at impact during practice swing practice without hitting the pole. This is the purpose.

In other words, it is attached to the golf head and detects and displays the maximum centrifugal force or swing speed when swinging the golf head, and also detects the light emitted upward from the golf mat and the magnetism generated by the permanent magnet installed on the golf mat surface. By detecting the timing of the impact, it is possible to practice a rational swing by checking the timing difference between the two and displaying the timing of the impact. An acceleration sensor is made by attaching a weight to the center of a concentric piezoelectric material bonded to a plate, and the voltage generated from this acceleration #i sensor is detected, and the time from the start of the swing to the moment when the maximum speed is generated is measured. an arithmetic/liquid crystal drive device that outputs a drive signal for a liquid crystal display for a certain period of time to display images; a light sensor or a magnetic sensor that detects light or magnetism from the golf mat surface; and an optical sensor or magnetic sensor that detects light or magnetism from the golf mat surface. A calculation/liquid crystal drive device that outputs a drive signal for a liquid crystal display for a certain period of time to display the time from the acceleration sensor in correspondence with the maximum speed generation point, and a liquid crystal display that displays two liquid crystal drive signals and a power supply. A golf ball consisting of a battery for use in golf, a case for storing these, etc., and characterized in that the vibration surface of the acceleration sensor is arranged approximately at right angles to the uranium shaft or approximately parallel to the ball hitting surface of the club head. ! This is a learning tool, and will be specifically described in detail below by showing examples.

(Example) FIG. 1 is a sectional view showing the configuration of a practice device to be attached to a golf club head.

A weight 4 is glued to the center of a concentric piezoelectric material 3 bonded to a disc-shaped metal diaphragm 2 to form an acceleration sensor B. A circuit board with a liquid crystal display C and an arithmetic/liquid crystal drive element F soldered thereon is installed on the inner upper part of the case 1.

In the practice device, it is inserted into the inner lower part of the through hole 11 provided in the crank head 8 so as to be approximately perpendicular to the club shaft,
Back cover 5 and club head sole plate for practice device] 0
and fixed so that they are located on the same plane. A transparent windshield 8 is provided on the upper surface of the club head, through which numerical values or signals displayed on a liquid crystal display can be visually recognized.

On the other hand, a light emitting element or a permanent magnet Gf is provided on the upper surface of the golf mat F, and the ball position display line N is set in such a state that the light emitting element or permanent magnet G corresponds to the window 9 of the back cover 5 of the practice device.
will be established.

The functions and effects of the golf practice equipment set consisting of the golf club and golf mant described above are as follows.

(Effects of the Invention) When the golf club equipped with the practice device K is swung during self-shooting practice, the acceleration sensor B of the practice device generates a voltage in response to the acceleration in the centrifugal force direction that is proportional to the acceleration in the swing direction of the club head A. do. The generated voltage gradually increases from the start of the swing, and after reaching the maximum acceleration, when the acceleration reaches zero, the generated voltage also becomes zero, and at this point the maximum swing speed is reached.

Although not shown, the same output waveform as above can be obtained even if the acceleration sensor Bt in the practice device is installed so as to be approximately parallel to the ball hitting surface of the club head, and the generated voltage is obtained directly from the acceleration in the swing direction. can be obtained.

Therefore, a certain threshold value S is set for the voltage generated by the acceleration sensor B, and the displayed bar graph is set at -° at constant time intervals T from the point in time when the generated voltage exceeds this threshold value S8 through the swing until the point in time when the generated voltage falls below the threshold value S8. By increasing the width, you can visually see when the maximum swing speed occurs.

On the other hand, from the point in time when the voltage generated by the acceleration sensor B exceeds the threshold value S, the golf club equipped with the practice device K passes over the light emitting element or the permanent magnet G provided on the top surface of the golf mat F, and the golf club attached to the practice device K passes over the light emitting element or the permanent magnet G provided on the top surface of the golf mat F. The time until the light or magnetic sensor E detects light or magnetism is counted at each fixed time interval T,
By displaying the bar graph in parallel with the maximum swing speed bar graph, the temporal relationship between the maximum swing speed point and the impact point can be visually recognized, thereby increasing the practice effect.

FIG. 3 is an example of a display on a liquid crystal display. The maximum head speed display bar graph M increases by a certain width C from left to right at fixed time intervals from the time when a certain degree of acceleration is applied to the acceleration sensor B from the start of the swing, and the acceleration decreases. incrementally increases up to the point in time. On the other hand, the impact display starts operating at the same time as the maximum head speed actual display bar graph M starts displaying, and is displayed at the same mark as the maximum head speed actual display bar graph M from the left to the right. moves, but does not display until there is an input from the optical or magnetic sensor E, and only the display position where the input from the optical or magnetic sensor E was received is displayed.

The optical or magnetic sensor E has a light-emitting element or a permanent magnet G set on the top surface of the golf mat F in a position that is activated only at the time of impact, so that the final display of the maximum head speed instantaneous bar graph M is displayed. By comparing the position and the display position at the time of impact, it is possible to determine whether the head speed is at its maximum or is appropriate for the time of impact, and then practice to obtain a desired swing.

FIG. 5 is an example of a circuit for a training device. The input voltage from the acceleration sensor B is amplified by an amplifier 1 and compared with a threshold value S by a comparator, and outputs a high level only while a voltage equal to or higher than the threshold value S is input. By inputting the number of pulses from the pulse generator during this high level time into the shift register 1.1 CD driver 1, the bar graph on the liquid crystal display C is lit for a length corresponding to the number of pulses.

On the other hand, the R-S flip-flop is set by the rising signal of the output from the comparator, and the optical sensor or magnetic sensor E
When the R-S flip-flop is reset with an amplified signal from . The number of pulses from the pulse generator during this high level time is transferred to shift register 2. By inserting it into the LCD driver 2, it is possible to light up the position M on the liquid crystal display C at the time of impact.

FIG. 6 shows another example of the circuit for the practice device. The output voltage from acceleration sensor B is converted into a digital quantity by the 7# A/D converter, inputted to the microcomputer, and the magnitude of the input is compared sequentially. The display C is operated one after another, and the human power from the optical or magnetic sensor E is also monitored almost simultaneously and sequentially by the microcomputer, and the display is maintained.

Move and display at the display position only when inputting via the LCD driver.

As mentioned above, the acceleration sensor B of the golf practice device attached to the club head generates a voltage proportional to the centrifugal force direction or the acceleration in the hitting direction toward the club, and the acceleration sensor B generates a voltage proportional to the acceleration in the direction of centrifugal force toward the club or in the direction of hitting the ball, and the acceleration sensor B generates a voltage proportional to the acceleration in the direction of centrifugal force toward the club or in the direction of hitting the ball. Since it is proportional, calculate the maximum head speed by multiplying it by an appropriate constant.el! It is most preferable because by using the golf practice equipment set of the present invention and practicing swinging, the relationship between the maximum head speed of the golf club swung and the timing at impact can be visually confirmed. You can practice without visually checking the condition, that is, the speed of the club head to be at its maximum during or after impact, and you can also visually check the maximum swing speed with a numerical display, so you can always check the results of your practice. Special feature that you can do! It is possible to provide a golf practice equipment set having i.
