Description

Digital Putter {DIGITAL PUTTER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf putter, and more particularly, to a digital putter capable of visually displaying a running direction of a putter head at the time of putting to help improve directionality of putting, in particular, straightness of putting.

Normally, it is puttering batting number 36 which occupies half of 72 regular total number of balls with 18 hole rounding standard of golf. While most golf players focus their time and effort on driver and iron exercises, puttings are simply learning how to hold grips and putting poses, and they rarely receive professional putting training.

In putting, in particular short putting within 2m, the straightness of the putter head is an important factor in determining the success of putting. Accordingly, various methods are practiced to advance the putter head straightly along the straight direction during putting. If the golfer is able to visually confirm the direction of the putter head in real time during his putting practice, the putting practice can greatly improve the straightness of the putter.

Conventionally, a plurality of inventions for improving the straightness of putting are disclosed.

Korean Patent Laid-Open No. 10-2005-0096658 discloses a golf putter using a laser beam. The putter includes a laser irradiator fixedly installed at a predetermined position of a putter neck for irradiating a laser beam having a straightness, And a display for calculating and displaying a distance to reach a target point by the light irradiated by the laser irradiated by the laser irradiator to display a putter for golf using a laser beam Korean Patent No. 10-1450189 discloses an image forming apparatus in which a base member having a light projecting body mounting portion in a striking direction of a head of a putter is installed on a main body portion of the putter on the upper side of a shaft of a putter, The light emitting unit is rotatably installed on the light emitting unit mounting portion of the base member, And an image formed on the bottom surface by light emitted from the laser light emission is moved in the putting direction in accordance with the rotation of the laser light emission or the like, and disclosed in Korean Patent Laid- The present invention relates to a light source device, comprising: a first light beam generator disposed at an upper end of a head face to generate a first light beam that advances in a direction of a target point; and a second light beam generator positioned in at least one of the shaft and the grip, Generating a second plurality of light beams projected toward the ground surface of the foot on which the golfer is located and generating a second light beam such that a virtual straight line connecting the ground projection points of the plurality of second light beams to each other is parallel to the first light beam And a second light beam generator, wherein the second light beam generator is provided.

These prior arts have an advantage of having a laser generator in a putter, showing a straight line to a target point using a laser beam, or accurately grasping a position or direction of a golfer to hit.

However, these prior arts have a disadvantage in that the puttering direction and the putting distance before putting are displayed, but the direction of the putter head measured in the actual putting process can not be measured. That is, the golfer can calibrate his putting by posteriorly confirming that he practically carried out the putting in the direction indicated by the laser beam, rather than by the putting direction indicated by the laser beam before putting practice, Prior arts have limitations in putting correction because they can not show the putting practitioner's straightness or direction of putter head movement in real time when putting.

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

≪ Example 1 >

As shown in FIG. 1, the digital putter according to the present invention displays the advancing direction of the putter head 1 on the upper surface of the putter head 1 during putting. To this end, the digital putter according to the invention comprises a face parallel LVDT (Linear Variable Differential Transformer) 23 arranged in the putter head 1 in a horizontal direction to the putter head 3.

The LVDTs 23 and 25 are displacement sensors capable of measuring a displacement to a fine range using a mutual inductance, and are electrically and mechanically separated from the coils 1S, 2Sa and 2Sb and the housing, The lateral displacement of the housing of the LVDT can be accurately measured using an electrical output proportional to the displacement of the housing (C). In the figure, for convenience of explanation, the magnetic core C, the primary coil 1S at the center of the outer side of the magnetic core C, and the primary coil 1S at both sides of the primary coil 1S are electrically separated from each other A pair of secondary coils 2Sa and 2Sb which are disposed and electrically connected to each other are electrically connected to each other. However, between the coils 1S, 2Sa and 2Sb and the magnetic core C, a lateral movement of the magnetic core C can be guided And the primary coil 1S and the secondary coils 2Sa and 2Sb are wound on the insulating cylinder. The mutual inductance between the primary coil 1S and one secondary coil 2Sa and the secondary coil 2Sb is changed according to the position of the magnetic core C when the sine wave is supplied to the primary coil of the intermediate portion, As a result, a difference occurs in the induced voltages generated in the secondary coils 2Sa and 2Sb on both sides, and as a result, the magnitude of the differential voltage generated across the secondary coils 2Sa and 2Sb changes. That is, when the magnetic core is located in the middle of the secondary coils 2Sa and 2Sb, an electromotive force having the same size and a phase difference of 180 ° is induced in both the secondary coils 2Sa and 2Sb, The mutual inductance between one of the secondary coils 2Sa and the primary coil 1S is the same as the mutual inductance between the other secondary coil 2Sa and the primary coil 1S. However, if the magnetic core moves, And the magnitude of the differential voltage is proportional to the displacement of the magnetic core C. In this case, the magnitude of the differential voltage is proportional to the displacement of the magnetic core C. In the present invention, the differential voltage is converted into a digital value by an A / D converter, and the value is used to calculate a putting direction by measuring a lateral movement displacement out of the straight direction control of the golfer during a putting operation.

Therefore, the face parallel displacement measurement magnetic sensor 23 should be arranged in a direction in which the magnetic core C advances in a direction parallel to the putter head face 3. Then, while the putter head 1 reciprocates while swinging with the back swing, the down swing, the impact and the arm swing, the putter head 1 does not move in the direction perpendicular to the putter head face 3, An inertial force in the opposite direction is generated in the magnetic core C of the magnetic sensor 23 to be displaced in the direction opposite to the displacement of the putter head while the magnetic field is applied to both ends of the secondary coils 2Sa and 2Sb A differential voltage is generated.

The present invention is characterized in that the putter head is provided with a putter head traveling direction display means for converting the differential voltage outputted from the face parallel displacement measuring magnetic sensor 23 into a parallel direction displacement, And the direction of movement of the putter head 1 is displayed.

1, the putter head advancing direction display means receives a differential voltage outputted from the face parallel displacement measuring magnetic sensor 23, converts the sampled differential voltage into a digital value, and outputs it to the microcontroller 15 An analog-to-digital converter 27 for receiving the differential voltage output from the AD converter 27, converting the differential voltage to a lateral displacement with respect to the time axis of the putter head 1, The microcomputer 1 calculates the moving direction of the putter head 1 by applying the displacement to each of the time points and controls the LCD 7 and the LCD driver 13 to control the micro 7 An LCD driver 13 for driving the LCD 7 under the control of the microcontroller 15 and a controller 15 for driving the LCD driver 13 and the putter head 1 of the microcontroller 15, The putter head (1) And a LCD (7) indicating the traveling direction. The battery 35 is connected to the DC output voltage microcontroller 15 of the battery 35 and the DC-DC voltage of the LCD driver 13 is boosted to a voltage level of the LCD driver for driving the microcontroller 15 and the LCD driver 13. [ And further includes a converter 37. The microcontroller 15 may output a rectangular wave to the LVDT driver 21 for AC power input of the primary coil 1S of the face parallel displacement measurement magnetic sensor 23. [ At this time, the LDVT driver converts a square wave into a sine wave by a low-pass filter or the like, and supplies the sine wave to the primary coil 1S of the face parallel displacement measuring magnetic sensor 23. The battery 35 is configured as a secondary battery so that it can be charged by a general-purpose SMPS (power supply device).

A power supply for separately outputting a square wave to the LVDT driver 21 may be separately provided and controlled by the microcontroller 15 or a sinusoidal wave may be directly generated in the face parallel displacement measurement magnetic sensor 23 And may be controlled by the microcontroller 15.

As shown in FIG. 1, in order to distinguish the backswing, the downswing, and the foot swing of the puttting, the microcontroller 15 can display the direction of the putting, It is preferable to further provide a face vertical LVDT 25 arranged in the direction of the arrow. The face vertical LVDT 25 maintains only the direction of arrangement perpendicular to the face parallel displacement measurement magnetic sensor 23, and its internal structure, AC power supply to the primary coil 1S and operation principle are the same as the face parallel displacement measurement And is the same as the magnetic sensor 23. However, the microcontroller 15 determines whether the direction in which the putting is performed by the differential voltage of the vertical LVDT 25 is a backswing (backward movement of the putter from the original position) or a downswing (movement of the putter from the backward position) (Forward movement of the putter from the home position), and in combination with the differential voltage input from the face parallel displacement measurement magnetic sensor 23, the direction of each swing section as shown in Fig. 1 Can be displayed. In Fig. 1, reference numeral 9a denotes a backswing (and downswing) direction display portion, and 9b denotes a foot swing direction display portion. The center point of the backswing direction display portion 9a and the arms swing direction display portion 9b represents the position of the ball.

Although the putting direction (putter head traveling direction) display may be displayed at a continuous real angle, it is preferable that the pitch angle of the putting head A fan-shaped indicator can be mounted in the front and rear direction to indicate the vehicle as ± auto-off values. That is, the moving direction of the putter head may be divided into a predetermined angle unit (for example, 5 ° or 15 °). The center lines of the putter head face 3 and the direction indicators 9a and 9b of the LCD are formed to be perpendicular to each other, and a fan-shaped indicator is formed on both sides thereof. At this time, if the actual angle is inconsistent with the unit angle, it is indicated by the indicator of the unit angle closest to the actual angle. Ensure that the largest line is displayed when calibrated to the centerline.

1, the putter head 1 is provided with a laser pointer 19 (not shown) capable of scanning laser light in a direction perpendicular to the putter head face 3 above the sweet spot points of the putter head face 3 And a laser driver 17 for driving the laser pointer 19 through the microcontroller 15. The golfer sets the first putter head direction to the target by the laser pointer 19 and performs the putting and confirms the actual proceeding direction of the putter head on the direction indicators 9a and 9b of the LCD 7 . That is, as shown in FIG. 4, the beam of the point laser 19 is projected in front of the putter face to confirm whether the golfer's posture is set to the correct position in the direction of the hole cup without moving the head. This can improve the direction and straightness of putting.

1, the putter head 1 further includes an impact sensor 31 capable of detecting a golf ball hit by the putter head 1, and a micro controller (not shown) 15 counts the number of putting times according to the input of the impact sensor 31 and accumulates and displays the number of putting on the putting number display unit of the LCD 7. The microcontroller 15 is preferably provided with a reset switch SW2 as well as a power switch SW1 so as to reset the putting number displayed by the golfer.

As shown in FIG. 1, the putter head 1 further includes a tilt sensor 33 for detecting when the putter head is inclined or inverted by more than a predetermined angle, The controller 15 preferably stops driving the LVDTs 23 and 25 and the laser pointer 19. As the tilt sensor 33, a MEMS type tilt sensor can be used. The ultrasonic distance measuring sensor may be attached to the tilt sensor so that the power switch SW1 is automatically turned off when the putter is separated from the ground by a predetermined distance or more.

Although not shown in the figure, the microcontroller 15 is further provided with a xyroscope module having a triaxial xylose scope sensor. The microcontroller 15 outputs a point at which the rate of change, which is output from the xyloscope module, It can be recognized as a point.

The LVDT 23 and 25, the LVDT driver 21, the microcontroller 15, the battery 35, the LCD 7, the LCD driver 13, and the laser pointer 19 and the laser driver 17 can be directly mounted on the putter head 1 as shown in Figs. 2 and 3, they are mounted inside the case 5 which can be detachably attached, 1 to be installed or separated. Fig. 4 shows a putter having a case with a built-in digital device according to the present invention attached to a putter head.

It is possible to attach the dental box to the structure of the general putter by attaching and detaching the dental box, and the power source can be charged with the charger by the mobile phone charger. The LCD box is mounted on the top of the digital box and the LCD line moves according to the head direction of the putter, And a laser beam is displayed on the front green of 30-50 Cm as long as you do not move your head by attaching a pointer laser to the front surface of the box, so that a stable stroke can be induced. At this time, the putter head 1 is designed in a comfortable stroke state in consideration of the rebound resilience and the weight due to the physical characteristics and taking into consideration the installation of the digital case 5.

As shown in FIG. 5, the 3-axis xyloscope module used at this time is a MEMS type 3-axis xyloscope. Since the three-axis xylophone sensor 28 outputs not only the rate of change of the rotational angles of the X and Y axes but also the rate of change of the rotational angle with respect to the Z axis, the use of the putter And can perform on / off control for the xyloscope module 26 and the laser pointer 19. [ When the output values of the xyroscope sensor 28 for all three axes are all 0, the standard point at which the putting starts can be used. Thus, using the xyloscope module 26 can reduce the components of the digital putter. The description of the other configurations of the second embodiment is the same as in the first embodiment.
