As described above, the putting information display device 1 is coupled to the shaft 11 of the putter 10 as shown in FIG. 3 so that the user displays information necessary for putting in actual putting or putting practice on the display unit 60.

  Hereinafter, embodiments of the information display mode will be described in detail.

In actual putting or practice putting, the user first turns on the putting information display apparatus 1.

At this time, the display unit 60 is set to the putting mode (PUT) as the initial information display mode, the user is the angle to display the angle of the putter head 12 in the putting mode (PUT) information display mode with the mode selection switch 31 You can change the mode (ANGLE), the slope mode (SLOPE) to display the green gradient, or the distance mode (DIST) to display the distance between the ball and the hole.

When the information display mode is the putting mode (PUT), when the user makes a down swing at the back address point, the angular velocity sensor 21 measures the angular velocity from the back address point to the down swing position.

That is, the angular velocity sensor 21 measures the angular velocity of rotation per unit time during the rotational movement of the putter 10 by the swing from the back address point to the down address point and outputs a change in voltage as analog data.

The digital data conversion element converts analog data output from the angular velocity sensor 21 into digital data and updates the digital data to the controller 50. The controller 50 outputs the output voltage of the angular velocity sensor 21 based on the updated digital data. The distance value corresponding to is calculated as the distance value from a table stored in advance, and the putting distance is displayed on the display unit 60.

Here, the output value of the angular velocity sensor 21 when there is no movement of the putter 10 is usually 1.35 V (based on 5 V of operating voltage). And when the rotational motion of the putter 10 is 1 ° per second, the output change of 0.67mV typically occurs. Therefore, the output voltage of the angular velocity sensor 21 becomes a conventional reference voltage of 1.35 V + 0.67 mV.

Based on this, for example, the table setting storage of the distance value corresponding to the output voltage of the angular velocity sensor 21, when putting, the angle from the back address to the down address is 40 ° and the time taken to rotate this 40 ° is 0.5 second. If it is, the time taken to rotate 40 ° is twice as fast, so that the output voltage of the angular velocity sensor 21 is 0.67 mV × 40 × 2.

According to the above formula, when the ball outputs 53.6mV from the angular velocity sensor 21 when putting, the ball flies by 10M. If the output voltage of the angular velocity sensor 21 is 5.36mV, the corresponding value is 10M. When the output voltage of the angular velocity sensor 21 is 0.5 mV, 1 M as the distance value and 10 Cm as the corresponding distance value are stored in advance in the controller 50 as a table.

Accordingly, the angular velocity sensor 21 measures the angular velocity of the putter 10 at the time of putting and displays the distance value of the table corresponding to the output voltage value numerically on the display unit 60. Therefore, the user can grasp the putting distance displayed on the display unit 60 by how much distance the ball is moved according to his swing ability, so that the user can learn and maintain the best putting sensation suitable for himself.

In addition, the putting distance displayed on the display unit 60 may be different from the distance that the actual ball flies depending on the putting ability of the user. In this case, the user may correct the up and down switches 32 and 33 of the input unit 30.

For example, the putting distance displayed on the display unit 60 after the user's putt is 10M, but when the actual ball flies, the putting distance is shorter than the putting distance displayed on the display unit 60, by pressing down switches 32 and 33 to actually putt the putt. The putting distance equal to the distance may be corrected to be displayed on the display unit 60. In this case, when the down switches 32 and 33 are pressed once, the range to be corrected may be corrected by 10%.

At this time, when the correction range is 20%, "-" and "20" are displayed on the display unit 60.

On the contrary, when the actual flying distance, that is, the actual putting distance is longer than the putting distance displayed on the display unit 60, the up switch 32 may be pressed to correct the actual putting distance.

At this time, when the correction range is 20%, "+" and "20" are displayed on the display unit 60.

In addition, the putting distance displayed on the display unit 60 may be displayed differently from the actual putting distance according to the actual green environment according to the weather as well as the putting ability of the user.

That is, since the degree of rolling of the ball on the actual green may change, such as when the green is wet immediately after the rain or when the green is very dry due to a dry weather, the putting distance displayed on the display unit 60 when the user is put as described above. It can be corrected by the method.

On the other hand, when the information display mode is the angle mode (ANGLE) for displaying the angle of the putter head 12, "ANGLE" is displayed on the display unit 60, the angular velocity sensor 21 is the putter head when the user puts the actual or practice When (12) is opened or closed and is out of the putting line, the changed angle of the putter head 12 is measured and output as analog data.

The digital data conversion element 40 converts analog data into digital data and updates the converted data to the controller 50, and the controller 50 displays the updated digital data on the display unit 60.

At this time, when the putter head 12 is opened at 0.4 degrees, "+" and "0.4" are displayed on the display unit 60. On the contrary, when the putter head 12 is closed by 0.4 °, "-" and "0.4" are displayed on the display unit 60.

Therefore, the user can learn the putting sensation of maintaining the correct putting line so that the hitting surface of the putter head 12 can strike the ball accurately during the swing from the back address point to the down address point.

On the other hand, the actual putting on the green should be putt according to the degree of inclination of the green and the distance between the ball and the hole cup bar, it is most preferable to measure the putting of the green slope and the distance between the ball and the hole cup.

To this end, the user may operate the slope mode SLOPE to measure the inclination of the information display mode of the putting information display apparatus 1 according to the exemplary embodiment, or the distance mode DIST to measure the distance between the ball and the hole cup. Press the mode selection switch 31 to change.

When the user selects the slope mode SLOPE, “SLOPE” is displayed on the display unit 60, and the user lays down the striking surface of the putter head 12 toward the green to measure the inclination of the green. The putter 10 is completely laid down as shown in FIG. 5 so that the handle of the 10 also touches the green.

In this state, the first tilt sensor 22a measures the inclination angle of the putter head 12 and outputs the inclination value. The digital data conversion element 40 converts analog data, which is a slope value of the putter head 12 output from the first tilt sensor 22a, into digital data and updates the digital data with the controller 50.

The controller 50 displays the distance value of the table corresponding to the inclination value of the putter head 12 on the display unit 60 based on the updated digital data.

At this time, when the inclination of the green is high and the inclination is 1.5 °, "+" and "1.5" are displayed on the display unit 60. In contrast, when the inclination of the green is high and the inclination is 1.5 DEG, "-" and "1.5" are displayed on the display unit 60.

On the other hand, when the user selects the distance (DIST) mode, "DIST" is displayed on the display unit 60, and the user matches the position of the ball with the position of the putter. The line of sight is fixed in parallel with 101, and the plurality of scales 101 are aligned with the hole cups H while the putter 10 is inclined toward the hole cups H.

As shown in FIG. 6, when the plurality of scales 101 matches the hole cups H, the second inclination sensor 22 measures and outputs an inclination value of the shaft 11 of the putter 10. The digital data conversion element 40 converts the inclination value output from the second inclination sensor 22 into digital data and updates the inclination value to the controller 50.

Based on the updated digital data, the controller 50 displays the distance value of the table stored in advance corresponding to the inclination value of the shaft 11 of the putter 10 on the display unit 60 as a number.

Therefore, the user can check the inclination of the green and the distance between the ball and the hole cup to adjust the swing degree when putting according to the inclination of the green and the distance between the ball and the hole cup, and increase the success rate when putting.

Here, the distance value between the ball and the hole cup previously stored in the table in the controller 50 is measured and stored in advance by a method of matching the plurality of scales 101 with the hole cup H as described above.

That is, the distance between the ball and the hole cup is maintained at 0.5M, the putter 10 is positioned in the same position as the ball, and the plurality of scales 101 are coincident with the hole cup. At this time, the reference value is set by setting the inclination value of the shaft 11 of the putter 10 obtained by the inclination sensor 22 to 0.5M.

In this manner, each of the inclination values measured up to 20M at 0.5M intervals is converted into a distance value and stored in the controller 50 as a table.

In addition, when a large amount of battery of the power supply unit 70 is consumed while the putting information display apparatus 1 is used, the display unit 60 may notify the user of the battery replacement time by blinking the battery icon.

As described above, the putting information display apparatus 1 according to the exemplary embodiment of the present invention may be easily attached to and detached from the various putters 10 held by the user by the detachable fixing unit 81. 10) The best putt in various green conditions while checking the information required for putting, such as actual putting, practice putting or preparing putt, putter head angle, green slope, distance to ball and hole cup, etc. You can keep your senses or correct your swing position.
