Example 2

When the golfer selects 'environment' by pressing the mode selection switch MODE in the initial screen display state, the controller 40 displays a screen for setting an environmental stride length (see FIG. 5) on the display unit 30. Allows golfers to set optimal stride values based on changes in the environment of the green (eg, weather such as snow, rain, dew, or temperature changes such as temperature, humidity, etc.).

For example, when the 'environment' mode is selected, the display unit 30 displays an initial screen for setting an environment stride, as shown in FIG. For example, when the putter is moved to the backswing address point such that 10.0m) is displayed, the acceleration sensor 21 outputs an acceleration detection signal, and accordingly, the controller 40 which detects a swing state of the putter is the ball and the hole cup. The putting speed and the backswing address point of the internal memory which are automatically set corresponding to the reference distance up to are displayed on the display unit 30 as shown in FIG. 5B.

For reference, (b) of FIG. 5 is an optimal condition for putting at a speed of 27.0 at a backswing address point of 18.2 for the reference distance of 10.0m, that is, a distance of 10.0m between a virtual ball and a hole cup according to environmental changes. Indicates that

When the golfer actually puts the putting information according to the environmental change as shown in FIG. 5 (b), the control unit 40 at the impact point of the putter face and the ball during the downswing, the acceleration sensor 21 The putting speed of the actual putter measured according to the acceleration change amount acquired from the acceleration sensing signal of is displayed on the display unit 30 as shown in (c) of FIG. 5 and corresponding to the currently displayed putting speed and backswing address point. The distance between the ball and the hole cup of the internal memory to be set is displayed.

For reference, the result of (c) of FIG. 5 indicates that the distance between the ball and the hole cup is 10.5 m under normal conditions, that is, conditions irrelevant to environmental changes, when putting at a speed of 28.0 at the backswing address point of 18.2.

As described above, the golfer presses the START switch of the operation switch unit 10 to measure the distance from the putting point to the point where the actual ball is placed in the state where the actual putting is completed, and the point where the ball is located at the putting point. After walking to the stop (STOP) switch, the control unit 40 calculates the environmental stride value by dividing the reference distance by the number of steps of the golfer obtained from the impact detection signal of the acceleration sensor 21, this environment The distance (environmental distance) between the ball and the hole cup calculated by multiplying the stride value by the measured number of steps is displayed on the display unit 30 as shown in FIG. 5 (d), and then the environment as shown in FIG. 5 (e). Displays the initial screen for measuring the distance according to the change.

After the initial screen for measuring the environmental distance as shown in (e) of FIG. 5 is displayed, the putting information display apparatus according to the present invention operates in the 'distance' mode (see FIGS. 8 and 9) described in detail below. The reference stride value set as in Example 1 is temporarily stored in the internal memory of the controller 40 until the 'environment' mode is released, and the newly set environmental stride value is set to the ball and the hole cup in the 'distance' mode. Used to measure the distance.

In addition, the release of the 'environment' mode can be released using the mode switch, etc., and when the 'environment' mode is released, the initial screen of the 'distance' mode described in detail below (see FIG. ) Is displayed on the display unit 30, and the reference stride value temporarily stored in the internal memory of the controller 40 is used to measure the distance between the ball and the hole cup in the 'distance' mode.

Example 3

When the golfer presses the mode selection switch MODE to select 'tilt' in the initial screen display state, the controller 40 displays a screen (see FIG. 6) indicating the inclination of the green on the display unit 30. When the golfer prepares for putting, putts practice, or putts, the slope of the green is used to adjust the strength of the putting speed to increase the putting success rate.

For example, when the 'tilt' mode is selected, the display unit 30 displays a screen for displaying the inclination of the green as shown in FIG. At this time, when the golfer is in close contact with the bottom surface of the putter head to the inclined green as shown in Figure 7 and pressing any one or another of the up / down switch (UP / DOWN) of the operation switch unit 10, The controller 40 calculates the inclination of the green corresponding to the inclination of the putter obtained from the inclination detection signal of the acceleration sensor 21 and displays it on the display unit 30 as shown in FIG. In this case, the downhill may be indicated by '-' or the like.

In addition, when the golfer presses any one or another of the above-mentioned up / down switches again or the predetermined time (eg, about 10 seconds) passes while the slope of the green is displayed as described above. The 'inclined' mode is released, and the initial screen (FIG. 8A) of the 'distance' mode described in detail below is displayed on the display unit 30.

On the other hand, the 'inclined' mode can be selected and released during the operation of the 'distance' mode described below, in this case, the controller 40 and the ball according to the actual distance measurement results as shown in (b) of FIG. When the putting speed and the backswing address point, which are set automatically in correspondence with the measuring distance and the measuring distance, are displayed on the display unit 30, the measuring distance is automatically adjusted according to the measured slope of the green. The putter speed and the backswing address point set are corrected and displayed on the display unit 30 so that the golfer can further increase the putting success rate when actually putting.

Example 4

When the golfer selects 'distance' by pressing the mode selection switch MODE in the initial screen display state, the controller 40 displays a screen for putting practice, distance measurement for putting preparation, and actual putting (FIGS. 8 and FIG. 9) is displayed on the display unit 30 so that the golfer can increase the putting success rate by using the putting information such as the distance between the ball and the hole cup displayed on the display unit 30, the putting speed, and the backswing address point.

For example, when the 'distance' mode is selected, the display unit 30 displays an initial screen for simple putting practice without distance measurement as shown in FIG. At this time, the controller 40 determines whether the golfer holding the putter is shaken from the shock detection signal of the acceleration sensor 21, and the degree of the shake is within the allowable range (for example, no shake for 1 second or more). Until the 'START' display of the initial screen blinks, and when it is determined that there is no camera shake, the 'START' display is released and the display unit 30 displays the screen as shown in FIG.

In this state, when the golfer starts the backswing, the control part 40 is the actual putter measured according to the acceleration change amount obtained from the acceleration detection signal of the acceleration sensor 21 until the golfer stops the putter at a specific backswing address point. The distance between the ball and the hole cup and the putting speed of the internal memory, which are automatically set in response to the change of the backswing address point and the backswing address point, is displayed on the display unit 30 as shown in FIG. In addition, until the golfer stops the putter at a specific backswing address point, the 'START' indication blinks and then stops the putter at a specific backswing address point, thereby releasing the blinking as shown in FIG.

Subsequently, when the golfer down swings for putting practice, the controller 40 measures the putting speed of the actual putter measured according to the acceleration change amount obtained from the acceleration detection signal of the acceleration sensor 21 at the impact point. As shown in e), the distance between the ball and the hole cup of the internal memory set in correspondence with the currently displayed putting speed is displayed, and then a predetermined time (for example, approximately 3 seconds) is displayed. After that, the initial screen for simple putting practice is displayed again as shown in FIG.

This simple putting practice without distance measurement is a practice for matching the actual putting speed of the golfer with the putting speed that is automatically set in response to a specific backswing address point, and the golfer can improve the putting sensation through this putting exercise.

After the simple putting practice without the distance measurement as described above, when the golfer presses the start (STATR) switch of the operation switch unit 10, the control unit 40 measures the actual distance as shown in FIG. The initial screen for displaying on the display unit 30.

Thereafter, the golfer carries the putter and walks from the current putting point to the actual hole cup, and then arrives at the hole cup and presses the STOP switch of the operation switch unit 10 to complete the actual distance measurement. 9 (b) displays a screen showing the distance between the ball and the hole cup according to the actual distance measurement result and the putting speed and the backswing address point which are automatically set in correspondence to the measurement distance on the display unit 30. .

The screen shown in (b) of FIG. 9 shows that the distance between the ball and the hole cup measured by the current golfer is 15.0 m, and the optimal condition for the successful putting is based on the putting speed of 33.0 at the backswing address point of 25.5. Since the distance between the ball and the hole cup is more than a predetermined reference distance (for example, 10.0m), the instruction to putt up the current putting speed at the current backswing address point is indicated by lighting 'PUT-PUSH'.

In this case, the controller 40 calculates and displays the distance between the actual ball and the hole cup in various ways as follows.

First, by using the UP / DOWN switch of the operation switch unit 10 to calculate by multiplying the number of steps of the golfer obtained from the count signal manually input by the golfer and a predetermined stride value of the golfer The distance between one ball and the hole cup is displayed on the display unit 30, and the reference putting speed and the reference back swing address point which are automatically set corresponding to the distance between the ball and the hole cup are displayed on the display unit 30. .

In this case, the reference stride value set in the first embodiment is basically used as the specific stride value, and when the 'environment' mode is selected, the environment stride value set in the second embodiment is used.

Secondly, the distance between the ball and the hole cup, which is calculated by multiplying the number of steps of the golfer obtained from the impact detection signal of the acceleration sensor 21 by a predetermined stride length of the golfer, is displayed on the display unit 30. The display unit 30 displays the reference putting speed and the reference back swing address point which are automatically set in correspondence with the distance between the ball and the hole cup.

In this case, the specific stride value is basically used as the reference stride value set in the first embodiment, and when the 'environment' mode is selected, the environmental stride value set in the second embodiment is used.

Third, the distance between the ball and the hole cup calculated by the trigonometric calculation using the slope of the putter obtained from the tilt detection signal of the acceleration sensor 21 and the preset length L1 of the putter is displayed. The display unit 30 displays the reference putting speed and the reference back swing address point which are automatically set in correspondence with the distance between the ball and the hole cup.

In this case, as shown in FIG. 10, the control unit 40 is positioned at the distal end of the putter handle in parallel with the green when the collimator 50 is in line with the hole cup to form 90 ° of the acceleration sensor 21. The slope of the putter obtained from the tilt detection signal is calculated as the internal angle θ between the putter and the green, and using the internal angle θ between this putter and the green and the length L1 of the putter already known and set in advance, the actual ball is And the distance L to the hole cup.

L1 / cosθ

As shown in (b) of FIG. 9, a screen showing a distance between the ball and the hole cup according to the actual distance measurement result and a putting speed and a backswing address point that are automatically set in correspondence to the measurement distance are displayed on the display unit 30. When the golfer selects the 'inclined' mode, the controller 40 operates in the 'inclined' mode as described above to determine the inclination of the green corresponding to the inclination of the putter obtained from the inclination detection signal of the acceleration sensor 21. It calculates and displays it on the said display part 30 as shown in FIG. Subsequently, when the 'distance' mode is released, the controller 40 corresponds to the distance between the ball and the hole cup according to the actual distance measurement result as shown in FIG. 9 (b) and automatically according to the slope of the green calculated as described above. The putting speed and the backswing address point to be corrected are set and displayed on the display unit 30. Thus, the process of additionally measuring the inclination of the green after measuring the actual distance can be omitted.

Subsequently, when the golfer prepares the putting practice swing or the actual putting at the putting point, a screen for the putting practice swing or the actual putting is displayed on the display unit 30 as shown in FIG. At this time, the controller 40 determines whether the golfer holding the putter is shaken from the shock detection signal of the acceleration sensor 21, and the degree of the shake is within the allowable range (for example, no shake for 1 second or more). The display of 'START' on the screen blinks until it is determined that there is no shaking, and the display of the display such as (d) of FIG. 9 is displayed on the display unit 30.

In this state, when the golfer starts the backswing, the controller 40 stops the putter at the optimal backswing address point displayed corresponding to the distance between the ball and the hole cup currently measured by the golfer. The backswing address point of the actual putter measured according to the acceleration change amount acquired from the acceleration detection signal is displayed on the display unit 30 as shown in FIG. 9 (e), and the golfer selects the putter at the optimal backswing address point. The 'START' indication flashes until it stops, and if the putter is stopped at a specific backswing address point, the blinking is released as shown in FIG. 9 (f).

FIG. 9 (f) shows a state in which the putter is stopped at an optimal backswing address point 25.5 for a successful putt with respect to a distance of 15.0 m between the ball and the hole cup currently measured by the golfer.

Then, when the golfer downswing for putting practice swing or actual putting, the controller 40 measures the putting speed of the actual putter measured according to the acceleration change amount obtained from the acceleration detection signal of the acceleration sensor 21 at the impact point. As shown in (g) of FIG. 9, the distance between the ball and the hole cup of the internal memory set in correspondence with the currently displayed putting speed is displayed.

In this case, when the golfer has practiced putting practice swing, the controller 40 displays a screen for putting practice swing or actual putting as shown in FIG. 9C after a predetermined time (for example, approximately 3 seconds). If it is displayed again, and the actual putting is performed, the controller 40 determines the actual putting from the shock detection signal of the acceleration sensor 21, and then displays the putting trajectory screen as shown in FIG.

By repeating the putt practice swing in accordance with the distance between the golfer's current ball and hole cup, the golfer will actually putt the optimal putting speed that is automatically set for the putting success and the golfer's actual putting speed. By improving your senses, you can reduce your putting mistakes and increase your success rate.

Example 7

After the golfer presses the mode selection switch MODE and selects 'distance' to make the putt, the control unit 20 opens or closes the putter head and displays a putting track indicating the degree of deviation from the putting line ( 11) is displayed on the display unit 30 so that the golfer can easily correct his / her wrong swing posture after putting.

For example, when the golfer actually puts as described above, the controller 40 determines the actual putting from the shock detection signal of the acceleration sensor 21 and then obtains the angle from the angular velocity detection signal of the gyro sensor 22. According to the amount of change, a putting track indicating the degree of deviation from the putting line by opening or closing the putter head is displayed on the display unit 30 as shown in FIG.

In this case, a reference line connecting a backswing address point and a putting point is displayed as a putting line on the putting track screen, and the controller 40 controls the gyro sensor at an impact point during downswing for actual putting based on the putting line. According to the angle change amount obtained from the angular velocity detection signal of (22), the putter head is opened or closed, and the degree of deviation from the putting line is displayed as a putting track in the form of a graphic such as a curve or a number such as an angle.

For reference, FIG. 11A illustrates a case in which the putter head is opened, that is, the putter head is out of the putting line in the toe direction of the golfer, and FIG. 11B illustrates a case in which the putter head is closed, that is, the golfer. The putter head is out of the putting line in the heel direction.
