Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1A and 1B, a putter measuring instrument 100 according to an embodiment of the present invention and a golf putting exerciser having the same include a putting meter 100 Detects a passing time of the golf ball 10 and provides various information for improving the putting ability of the user.

Since the putter measuring instrument 100 is not fixed on the ground but is small in size, it is portable and can be used not only in the putting course 200 but also in an artificial turf, a golf driving range, an actual golf course, and the like.

Further, when the putting measuring instrument 100 is used on the putting course 200, an improved putting training effect can be seen.

2 to 5, the putter measuring apparatus 100 according to the embodiment of the present invention includes a housing 110 installed in a path along which a putt golf ball 10 moves, A plurality of distance sensors 120 which are provided to be spaced apart from each other and detect the golf ball 10 and the golf club 20 which move within the respective detection ranges and a golf ball 10 An arithmetic unit 150 for calculating a predicted travel distance of the golf ball 10 based on the detected time difference and a golf club 20 staying in the detection range of any one of the distance sensor 120 provided below the housing 110 And a moving unit 170 that moves the housing 110 in the direction of the distance sensor 120 that detects the golf club 20.

In addition, the upper portion of the housing 110 further includes a putting display 160 for displaying information calculated by the calculating unit 150.

A sensor guard 112 is coupled to an upper portion of the housing 110. The sensor guard 112 is elongated in a lateral direction in which the distance sensor 120 is installed and has an end bent downward.

The distance sensor 120 is for detecting a golf ball 10 struck by the golf club 20 and a golf club 20 staying in the detection range for driving the moving unit 170, It is preferable to detect them in a non-contact manner so as not to disturb the movement.

The golf ball 10 sequentially passes through the detection range of the distance sensors 120 installed on the side of the housing 110 while the golf ball 10 moves adjacent to the housing 110. The calculation unit 150 calculates the distance The estimated travel distance of the golf ball 10 can be calculated by the time that has passed through the detection range of each of the distance sensors 120. [

The distance sensor 120 may be a proximity sensor, an optical sensor, an ultrasonic sensor, or the like, which is a non-contact type sensor.

4, the distance sensor 120 may include an optical sensor including a light emitting unit 120a for outputting an optical signal and a light receiving unit 120b for receiving the optical signal. In this case, The light emitting portion 120a and the light receiving portion 120b of the optical sensor may be installed to face each other while being separated from the side surface of the housing 110 and the end of the sensor guard 112. [

Since the optical sensor includes a laser sensor, an infrared sensor, and the like depending on the type of light used, the distance sensor 120 may select any one of the optical sensors, or may use the optical sensor according to circumstances.

Thus, when the golf ball 10 passes between the housing 110 and the end of the sensor guard 112, the distance sensor 120 can detect the golf ball 10.

In order to calculate the expected travel distance of the golf ball 10, a distance and time of at least two sections are required. 2 and 3, the distance sensor 120 includes at least three primary sensors 121 for detecting the moving golf ball 10 at first, A secondary sensor 123 for detecting the golf ball 10 and a tertiary sensor 125 for detecting the golf ball 10 following the secondary sensor 123. [

When the golf ball 10 is detected by the primary sensor 121, the arithmetic unit 150 starts the time measurement and calculates the delay time until the golf ball 10 is detected by the secondary sensor 123, 125 to store the delay time until the golf ball 10 is detected and calculate the estimated travel distance.

For this purpose, it is preferable that the respective distance sensors 120 are arranged in order in the direction in which the golf ball 10 passes through the side surface of the housing 110.

When the passage of the golf ball 10 is detected by the distance sensor 120, the calculation unit 150 starts to calculate the estimated travel distance of the golf ball 10.

Modeling for calculating the predicted running distance s1 of the golf ball 10 will be described as follows.

[Equation 1]

X1 is a distance between the primary sensor 121 and the secondary sensor 123 and x2 is a distance between the secondary sensor 123 and the tertiary sensor 125. [ T1 is the difference in time between the detection of the golf ball 10 by the primary sensor 121 and the detection of the golf ball 10 by the secondary sensor 123 and t2 is the time difference between the detection of the golf ball 10 by the secondary sensor 123 and the tertiary sensor 125, (10) is detected.

Since the distance sensor 120 is fixed to the housing 110, x1 and x2 are stored in the arithmetic unit 150 as constants.

The calculation unit 150 calculates the distance between the distance sensors 120 and the time that the golf ball 10 has passed through the first sensor 121 and the second sensor 123 and the third sensor 125, The estimated travel distance of the golf ball 10 can be derived.

The separation distance between the primary sensor 121 and the secondary sensor 123 is arranged to be longer than the separation distance between the secondary sensor 123 and the tertiary sensor 125 in order to improve the accuracy of the estimated traveling distance.

The moment when the golf ball 10 is hit by the golf club 20, the golf ball 10 may bounce to the air for a while. When the golf ball 10 moves in the air, it receives less frictional force than the ground, It becomes possible to move for a faster time. However, when the golf ball 10 moving in the air touches the ground, the speed of the golf ball 10 decreases sharply and moves the same distance for a longer time than in the air.

If the primary sensor 121 detects the golf ball 10 moving in the air and the golf ball 10 touches the ground while approaching the secondary sensor 123, The arrival time of the golf ball 10 detected by the golf ball 123 is a mixture of the time when the golf ball 10 moved to less friction in the air and the time when the golf ball 10 moved to a larger friction on the ground.

When the estimated travel distance is calculated by the mixed time, the error of the estimated travel distance becomes large.

Accordingly, when the distance between the primary sensor 121 and the secondary sensor 123 is further distanced, the distance at which the golf ball 10 rolls on the ground becomes longer, and relatively moving in the air Since the distance decreases, it is possible to reduce the error of the estimated travel distance.

Further, as another method for improving the accuracy of the estimated mileage,

The computing unit 150 further includes a fourth sensor 127 for detecting the golf ball 10 following the sensor 125. The computing unit 150 computes the distance x2 between the second sensor 123 and the third sensor 125, The difference t2 between the times when the secondary sensor 123 and the tertiary sensor 125 detected the golf ball 10 and the distance t2 between the tertiary sensor 125 and the fourth sensor 127, and the difference t3 between the time when the third sensor 125 and the fourth sensor 127 detect the golf ball 10 are combined to calculate the auxiliary estimated travel distance s2.

The auxiliary assisted driving distance can be calculated by replacing x1 in the search formula 1 with x2, x2 with x3, t1 with t2, and t2 with t3.

The final estimated travel distance S, which is more similar to the actual travel distance, can be calculated as the average of the calculated auxiliary estimated travel distance s2 and the estimated travel distance s1.

Alternatively, the friction coefficient value of the course, which affects the movement of the golf ball 10, can be combined with the calculation of the expected mileage, as another way to improve the accuracy of the expected mileage.

In order to set the friction coefficient value, the housing 110 is provided with a roughness setting button 140 that allows the user to directly set the friction coefficient of the course.

The user can increase or decrease the friction coefficient value by operating the roughness setting button 140. Since the variable friction coefficient value that is changed each time the roughness setting button 140 is operated is displayed on the putting display 160, .

Here, the course refers to all the places where the putting exerciser or the putter measuring instrument 100, such as another putting exerciser or a field, is arranged to perform the putting practice by the user.

It is difficult for the user to accurately know the coefficient of friction of the course having the unevenness and the inclination. However, when comparing the actual driving distance of the golf ball 10 with the expected driving distance displayed on the putting display 160 while putting, The coefficient of friction can be set to a level that becomes similar to the distance.

For ease of operation, the roughness setting button 140 may be provided on the upper portion of the housing 110 as shown in the figure, and a remote controller that can be set wirelessly may be added according to the embodiment.

6, the putting display 160 is provided on the top of the housing 110 to visually provide information useful to the user.

The helpful information includes a variety of information calculated by the operation unit 150, that is, a predicted driving distance, so that the user can check the strength of each putting by numerical values, and the number of times of putting is also displayed, The number of times can be checked.

When the putting measuring instrument 100 is used on the putting course 200, the distance to the putting measuring instrument 100 and the hole cup 212 is output to the putting display 160, And can display the putting accuracy of the user together with whether or not the golf ball 10 is a golfer's goal.

Since the moving distance of the golf ball 10 putted by the user is predicted and output in the putting display 160, there is no fixed target such as the hole cup 212, and the putting force control is practiced even in a very narrow environment where the wall is adjacent to the front face can do.

When the putting display 160 is provided on the upper portion of the housing 110, the user can check the putting display 160 while viewing the golf ball 10 positioned on the ground for putting.

The moving part 170 automatically moves the housing 110 forward and backward.

The moving direction of the moving unit 170 is controlled by a plurality of the flying distance sensors 120. As shown in FIGS. 7A and 7B, in the detection range of the secondary sensor 123 of the flying distance sensor 120, 20), the moving part 170 is driven in the forward direction to advance the housing 110 (left side in the drawing). When the golf club 20 is positioned within the detection range of the primary sensor 121, 170 are driven in the backward direction so that the housing 110 is moved backward (right side in the figure).

It is difficult to distinguish whether the distance sensor 120 as the non-contact sensor is the golf ball 10 or the golf ball 20 as soon as the golf ball 20 is detected. However, when the distance is detected by the distance sensor 120, And the golf club 20 can be distinguished from each other.

For example, in a situation where the distance sensor 120 detects the movement of the golf ball 10 to which the golf ball 10 has been put, the golf ball 10 is moved from the primary sensor 121 to the last distance sensor 120 However, when the user desires to drive the moving part 170, the golf club 20 will stay within the detection range of any one of the distance sensors 120.

Therefore, when the light of the optical sensor is blocked for a predetermined time in the detection range of any of the distance sensors 120, the calculation unit 150 estimates that the golf ball 20 is positioned at the corresponding position, It can be driven in a corresponding direction.

The moving unit 170 may include an electric motor (not shown) fixed inside the housing 110 to generate a driving force, and a wheel 171 mechanically coupled to the electric motor.

Since the putter measuring instrument 100 can be automatically moved on the course through the moving part 170, the user can practice putting at various distances from the hole cup 212, and whenever the putting position is changed, the putting meter 100 ) Is removed.

The sensor guard 112 is slidably coupled to the upper portion of the housing 110 so that the sensor guard 112 can be inserted into the housing 110.

Since the distance sensor 120 is provided opposite to the end of the housing 110 and the sensor guard 112 so that the distance of the sensor guard 112 protruding from the housing 110 can be detected It becomes an area that can be made. As the length of the sensor guard 112 protruding from the housing 110 is varied, the area in which the golf ball 10 can be detected can also be varied.

Therefore, if the protruded length of the sensor guard 112 is varied, it is possible to perform the putting practice by disposing the putting measuring instrument 100 on an established putting practice course having various widths, and it is necessary to carry or store the putting measuring instrument 100 The volume of the sensor guards 112 can be reduced by sliding the sensor guards 112 into the housing 110 as much as possible.

8 and 9, the golf putting exerciser according to the embodiment of the present invention is formed long in one direction to improve the effect of putting practice, and golf putting is performed at the upper part, and the putting meter 100 And a putting course 200 which is moved along the longitudinal direction through the moving part 170. [

The upper surface of the upper plate 210 may be attached with a green artificial grass or a nonwoven fabric to reproduce the environment of the golf course where the grass grows. In addition, it is preferable that the hole cup 212 in which the golf ball 10 is drawn is formed adjacent to one end of the upper plate 210 to practice putting.

In order to accurately determine the distance between the hole cup 212 and the housing 110, a scale 216 having a distance from the hole cup 212 is formed on the side surface of the upper plate 210. The housing 110 is connected to the upper plate 210 And a position detection sensor 130 provided to scan the scale 216 at a portion facing the side surface of the wafer W.

The putting measuring instrument 100 scans the scale 216 with the position detection sensor 130 while calculating the distance from the hole cup 212 while moving along the longitudinal direction of the upper plate 210 of the putting course 200, On the putting display (160). Since the distance between the hole cup 212 and the putting measuring instrument 100 and the estimated driving distance of the putting golf ball 10 are displayed together on the putting display 160, the user can easily access the golf ball 10 So that it is possible to more precisely control the force.

In order to improve the user's putting training effect and to add fun, a bone detection sensor (not shown) for automatically detecting the golf ball 10 passing through the hole cup 212 is provided below the upper plate 210 at the position where the hole cup 212 is formed 214 are fixed.

The operation unit 150 receiving the fact of the goal through the course communication unit 215 displays the goal success rate calculated by the number of times the goal has been completed to the total number of putts in the putting display 160 as shown in FIG. 6, And the like.

The communication module (not shown) corresponding to the putting measuring instrument 100 is configured to be connected to the operation unit 150 in order to communicate with the course communication unit 215 of the putting course 200.

The putting course 200 further includes a course display 240 that is provided to face the housing 110 and outputs a goal mark when the bone detecting sensor 214 detects passing of the golf ball 10 through the hole cup 212 So that the user can enjoy putting practice more enjoyably.

The goal display displayed on the course display 240 may be a message or an image for visually celebrating the goal of the golf ball 10 and a speaker may be added to the course display 240 to output music and sound effects .

9, the terrain type variable portion 230 is constituted by a plurality of left and right sides between the upper plate 210 and the lower plate 220 and is individually driven to support the upper plate 210 and the upper plate 210 To form inclination of various angles and directions up and down and left and right.

The topographic type variable section 230 includes a topographic type variable motor 232 fixed to the bottom plate 220 and a top type variable motor 232 mechanically coupled to the top plate 210 while being moved up and down by the topographic type variable motor 232, And an upper plate support portion 234 for lifting and lowering the upper plate.
