Description

Digital Stimp-meter}

The present invention relates to a digital steam meter, and more particularly, to a rod-shaped digital steam meter used for calculating a green speed representing a grass condition of a green with a hole cup as a final target point at a golf course.

Generally, a stimp-meter is a device used to measure the speed of a green of a golf course having a hole cup. It measures the speed of the green, which changes according to the height of the green grass and the cutting direction. So that the player can perform stable putting.

As shown in FIG. 1, a golf ball (B) is placed in a catching groove of a green (G) stamper meter to measure a speed and a shaft (103) When the rear end is slowly lifted, the golf ball B rolling down along the rolling groove 105 at about 30 degrees moves along the green G and stops at an arbitrary position.

Next, the user measures the distance from the tip of the shaft 103 to the golf ball using a measuring instrument such as measuring the distance. For example, three times in the same direction, three times in the opposite direction, And the final green speed is confirmed by the average value.

However, in the conventional steam meter 101 described above, the user must directly measure the moving distance manually by using the measuring instrument every time the golf ball B is rolled. Thus, the green speed measuring operation is very cumbersome, There is a problem that it takes a long time.

The golf ball B rolling down to the green G due to the inclination of the green G which lies to the left and right in the traveling direction of the golf ball B moves to the right side of the shaft 103 in accordance with the green G to be measured, There is a problem that the measurement of the green speed is performed incorrectly, for example, the reference point of the length measurement is changed.

The present invention has been proposed in order to solve the problems of the conventional steam meter as described above. In order to measure the green speed, a steam meter So that it is possible to accurately measure the color speed in real time by itself to confirm the green speed.

In addition, by measuring the distance that the golf ball rolled down to the green rolls toward the front side of the shaft, the distance of the golf ball in the width direction of the shaft is calculated while measuring the green speed, thereby determining the left and right inclination of the green. Another goal is to increase the accuracy of the measurement.

Another object of the present invention is to allow the user to check the measured distance of the golf ball in real time as well as the measured distance of the golf ball in real time.

In addition, there is another purpose of grasping the gradient of the target green.

In order to achieve this object, the present invention provides an apparatus comprising: a longitudinally extending shaft; Wherein the golf ball is formed on the upper surface of the shaft in a longitudinal direction so that when the shaft front side is raised on the green and the rear side of the shaft is lifted, the golf ball placed on the shaft is guided downward along the shaft, Rolling grooves rolling over said green; And a metering module installed on the shaft and measuring a moving distance of the golf ball from the emitting end to the green as it lifts the rear side of the shaft.

Preferably, the measuring module includes distance measuring means attached to a front end of the shaft for measuring a moving distance of the golf ball.

Preferably, the measurement module extends in the width direction of the shaft, and the distance measurement means includes at least two or more distance measurement means on each side in the width direction.

Preferably, the distance measuring unit is a distance measuring unit using any one of a laser, an infrared ray, and an ultrasonic wave.

In addition, the measurement module preferably includes a display for displaying a moving distance of the golf ball measured by the distance measuring unit.

In addition, the measurement module preferably includes a level meter for visually displaying the degree of inclination of the shaft.

According to the steam meter of the present invention, the measurement module installed at one end of the shaft, preferably at the tip portion, more specifically, the distance measurement means such as a distance measuring instrument provided on the measuring module, Since the moving distance of the golf ball can be measured and displayed in real time, the accuracy of the moving distance measurement value can be further improved as compared with the manual measuring operation, and the measurement operation itself can be performed very conveniently and quickly .

In addition, since the distance that the golf ball moves in the direction perpendicular to the measurement direction of the green speed, that is, the width direction of the shaft can be measured, and the right and left inclination can be confirmed through the level system, the golf ball can not go straight, The accuracy of the green speed measurement can be improved, for example, the distance can be confirmed.

Hereinafter, a digital steam meter according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The digital steam meter of the present invention comprises a shaft 3, a rolling groove 5, and a measuring module 7 as shown in FIG. 2 through FIG.

Here, the shaft 3 constitutes the body of the steam prime mover 1 and is made of a rectangular metal member elongated in the longitudinal direction as shown in Figs. 2 to 4. However, considering that the steam meter 1 is portable, it is preferable that the shaft 3 is made of a lightweight material.

The shaft 3 is arranged so that the bottom surface of the front end is parallel to the green surface when the shaft 3 is tilted by the measurement angle q at the green (G) speed measurement position as shown in Fig. 7 by the measurement angle q It has a slanted bevel. 2, the shaft 3 is provided at the center of the rolling groove 5 so as to hold the golf ball B at a rear-end adjacent position for a predetermined time before it is inclined to the measurement angle q, Is formed.

The rolling groove 5 is guiding means for guiding the golf ball B along the shaft 3 when the speed of the green G is measured. As shown in Figs. 2 to 4, The golf ball B placed on the engagement groove 19 on the rear side when the front side of the shaft 3 is placed on the green G and the rear side of the shaft 3 is lifted up to the measuring posture in green (G) The golf ball B rolled down through the discharge end 11 formed at the front end of the shaft 3 is formed in the longitudinal direction on the upper surface of the shaft 3 so as to be guided downward along the shaft 3 by its own weight, To the green (G).

It is also preferable that the rolling groove 5 has an inverted triangular cross-sectional shape as shown in Fig. 4 so as not to rock in the width direction of the shaft 3, right and left while the golf ball B rolls down . However, as shown in FIG. 3, it is preferable that the rolling groove 5 be shallower as the depth of the groove becomes smaller toward the front, so as to reduce frictional resistance applied to the golf ball B.

As shown in Figs. 2 to 4, And at least one distance measurement means 13 is provided to measure the distance between the shaft 3 and the shaft 3 when the shaft 3 is lifted up behind the shaft 3, The moving distance of the golf ball B that has been rolled over the golf ball G is measured instantaneously in real time. In this case, various types of digital devices may be used as the distance measuring means 13, for example, a laser distance measuring device, or a distance measuring device equipped with an infrared sensor or an ultrasonic sensor may be used.

In particular, the measurement module 7 preferably extends in the width direction of the shaft 3, as shown in Figs. This is because a plurality of distance measuring means 13 are arranged in the width direction of the shaft 3 so that not only the lengthwise movement distance but also the widthwise movement distance of the golf ball B can be measured. That is, each of the laser range finders has a measuring range of more than a certain width from left to right as used in, for example, a speed gun, and a plurality of the laser range finders are arranged adjacent to each other within the measuring range, 5, the distance L in the longitudinal direction at the center of the discharge end 11 can be measured to confirm the distance the golf ball B has moved forward, 11) It is also possible to check the distance that the golf ball B is sideways by measuring the distance W in the widthwise direction from the center. To this end, as shown in FIGS. 2 to 5, the measuring module 7 is provided with at least two or more distance measuring means 13 on one side in each side in the width direction.

On the other hand, the measuring module 7 may further include a leveling instrument 15 for measuring the degree of inclination of the shaft 3 placed on the green G, as shown in Figs. At this time, the leveling instrument 15 may be of a type in which the inclination degree is measured visually as well as the degree of the inclination degree is measured electronically.
