Swing angle guidance laser irradiation type golf putter {GOLF PUTTER THAT IRRADIATE LASER TO GUIDE SWING ANGLE}

The present invention relates to a swing angle guide laser irradiation type golf putter. In particular, when a laser is irradiated to a hole cup, the distance from the head of the golf putter to the hole cup is measured, and the back swing angle according to the distance is calculated to back the golf putter backward. It relates to a swing angle guide laser irradiation type golf putter capable of increasing the putting success rate by irradiating a laser corresponding to the swing angle.

A golf putter is a club that a golfer uses to hit the ball toward the hole cup on the green, and it is the club most often used by golfers during a game. Since the putter is such an important golf equipment, various products are available to improve the functionality. In terms of the shape of the head, it can be divided into a 'blade type' of a traditional classic style and a 'mallet type' of a large head that is in vogue recently. The blade type is advantageous for golfers with a stable stroke and excellent directionality, and a mallet putter with a large head has a large moment of inertia, so it provides accuracy of putting and stability of stroke. To enhance the performance of the face (ball surface), precision milling or inserting other materials such as polymer into the putter face were also developed. The purpose of the insert putter is to improve the feel at impact and strengthen the rotational force of the ball. In the case of face milling, there is a face digging in the form of a groove from a delicate CNC method. Both methods were developed to improve the rotational force and straightness of the ball. The developed products can also be classified according to the shaft. It can be divided into 'center type' and 'heel type' according to the position where the shaft is inserted, and it is divided into 'straight type', 'offset', 'band type' and 'shape type' according to the shape. Depending on the length of the shaft, there is also a belly putter, which is being used by famous pros recently.

The shaft 20 is a part constituting the overall body, and the receiving part 23 for accommodating the upper laser irradiation part 40 is mounted on one upper side.

The grip 10 is disposed on the shaft 20 and serves as a handle that is easy for a golfer to grip by hand.

The head unit 30 is disposed under the shaft 20 to directly hit the ball, and the lower laser irradiation unit 50 forming the putting line PL is mounted thereon.

The key operation unit 100 is disposed on one side of the grip 10 and serves to set the distance calculation mode, the laser irradiation mode, and the calibration mode by the user's key operation.

The distance calculation mode is a mode in which the distance from the head unit 30 to the hole cup H is calculated by the distance measuring unit 200 .

The laser irradiation mode irradiates a laser through the lower laser irradiation unit 50 to form a putting line PL from the head unit 30 to the hole cup (H), as well as a back swing angle through the upper laser irradiation unit 40 . It is a mode for irradiating guide lasers (eg, L1, L2, L3, L4) corresponding to (eg, θ1, θ2, θ3, θ4).

The calibration mode is a mode that allows calibration while giving an error to the back swing angle calculated by the swing angle calculator 300 .

The upper laser irradiation unit 40 is mounted on the shaft 20 through the receiving unit 23 to guide lasers (eg, L1, L2, L3, L4) according to the back swing angle (eg, θ1, θ2, θ3, θ4). plays a role in investigating Because golfers swing back according to the guide laser, it is possible to improve the putting success rate along with the effect of correcting posture according to distance.

The lower laser irradiation unit 50 is mounted on one side of the head unit 30 and serves to form a putting line PL reaching the hole cup H by irradiating the laser with the hop cup H.

In addition, the lower laser irradiation unit 50 serves to receive the reflected laser when the golfer lifts the head unit 30 and irradiates the laser to point the hole cup (H).

The accommodating part 23 is mounted on one side of the shaft 20 and serves to accommodate the upper laser irradiation part 40 . Since the position of the upper laser irradiator 40 is variable in order to irradiate the guide laser according to the back swing angle, the accommodating part 23 must be able to accommodate the upper laser irradiator 40 whose position is variable.

The distance measuring unit 200 is when the golfer holds the grip 10 and lifts the head 30 and irradiates the laser through the lower laser irradiation unit 50 and points the hole cup (H), the laser is reflected and returned to the lower laser irradiation unit Measure the time (t) received by (50), calculate the distance (d) from the head part 30 to the hole cup (H) using the following [Equation 1], and calculate the swing angle of the calculation result It serves to provide to the unit 300 .

[Equation 1]

d=t/2×c

[here, d represents the distance from the head to the hole cup, t represents the time until the laser is irradiated from the laser irradiator toward the hole cup and received, and c represents the speed of light]

The swing angle calculation unit 300 recognizes the distance from the head unit 30 to the hole cup (H) calculated by the distance measurement unit 200, and the distance from the built-in head unit 30 to the hole cup (H). It serves to calculate the back swing angle using the versus back swing angle table, and provide the result to the beam driver 400 . As the distance from the head part 30 to the hole cup H increases, the back swing angle increases. This is the principle of increasing the back swing angle to increase the putting power as the distance increases.

FIG. 2 is a view showing a guide laser and a putting line irradiated according to a back swing angle from the upper laser irradiation unit of FIG. 1 .

For example, if the back swing angle calculated by the swing angle calculator 300 is θ1, θ2, θ3, and θ4 with respect to the reference line LO, the guide laser irradiated from the upper laser irradiator 40 is L1, L2, L3. , becomes L4.

When the calibration mode is selected by the key operation unit 100 and the error is adjusted, the calibration unit 500 performs calibration while giving an error to the back swing angle calculated by the swing angle calculation unit 300. It serves to adjust the back swing angle according to the golfer's putting power.

That is, when a golfer with good putting power performs a back swing along the guide laser corresponding to the back swing angle calculated by the swing angle calculation unit 300, the golf ball can fly farther than a golfer with a standard putting power. Therefore, the back swing angle can be reduced through the calibration unit 500 . Conversely, a golfer having a putting force that is less than the standard putting force may adjust the back swing angle to increase the back swing angle through the calibration unit 500 .

The beam driving unit 400 is operated when the shaft 20 is placed vertically by a colper. In more detail, the beam driving unit 400 drives the lower laser irradiator 50 to irradiate the laser to the hole cup H to form the putting line PL, and, at the same time, by the swing angle calculation unit 300 It serves to irradiate the guide laser corresponding to the back swing angle by driving the upper laser irradiator 40 based on the calculated back swing angle.

At this time, the golfer determines the putting direction by referring to the putting line (PL), and by making a backswing as much as the guide laser corresponding to the backswing angle to putt, the posture correction effect according to the distance can be obtained, and the putting success rate can be increased can

According to the swing angle guide laser irradiation type golf putter according to the embodiment of the present invention configured as described above, when the golfer irradiates a laser from the lower laser irradiation unit and points the hole cup, the distance from the head to the hole cup is measured by measuring the reflected and received time. Calculate the back swing angle using the distance from the head to the hole cup versus the back swing angle table using the calculated distance from the head to the hole cup, and drive the lower laser irradiation unit to irradiate the laser to the hole cup and putt In addition to forming a line, by driving the upper laser irradiation unit based on the calculated back swing angle to irradiate the guide laser corresponding to the back swing angle, it is possible to correct the golfer's swing form and increase the putting success rate. It has an excellent effect.
