6 is a block diagram of a golf aiming device according to an embodiment of the present invention.

Hereinafter, a golf aiming device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components or parts are denoted by the same reference numerals as much as possible.

When a golfer hits a golf ball, after determining the desired target direction (this is called 'aiming'), take an address so that both feet are at a right angle to the target direction, and direct the club head in the target direction to hit in the desired direction.

In particular, in the case of a novice golfer, there are cases in which a golf tee indicating the direction is used when a ball is placed on a golf tee in the starting area of each hole and the first shot, the tee shot, is used. Also, if you place two iron clubs as a cross in order to accurately capture the target direction before taking a fairway shot, and hit with reference to this, it will also violate Article 8, Paragraph 2 of the Golf Rules.

Therefore, the golf aiming device according to the present invention uses two light sources 110 and 120 as shown in FIG. 1 in the form of a ball marker to irradiate a laser beam in an address direction with a difference of a predetermined angle (90 degrees) from the target direction to irradiate a tee shot. , It induces the golfer to hit the golf ball accurately in the desired direction during fairway shots and putting shots.

Here, when aiming and addressing with reference to the laser beams irradiated from the two light sources 110 and 120 before tee shot, fairway shot, and putting shot are completed, the golf aiming device 10 according to the present invention must be removed and hit the ball You must not receive two penalty strokes under the golf rules (Article 8, Paragraph 2).

2 is a perspective view of a golf aiming device according to the present invention, and the golf aiming device 10 has a round ball marker shape generally used at the time of putting, and the upper surface 100 is a first for irradiating a laser beam in a target direction. The first light source 110 and the second light source 120 for irradiating the laser beam in the address direction are arranged to have a difference of 90 degrees. A printed circuit board (PCB) circuit implementing the block diagram shown in FIG. 6 is embedded in the upper surface 100 .

The lower surface 300 is made of a lightweight metal material so that it can be attached to a general marker holder (not shown) having a magnetic material in the form of a clip on a golf cap.

The bellows 200 that is coupled between the upper surface 100 and the lower surface 300 and is elastically deformed of rubber or silicone material is implemented with a minimum thickness and the golf aiming device 10 used as a ball marker is based on the hole cup. In order to place the golf ball at a position as close as possible to the rear of the golf ball, as shown in FIG. 3 , a bellows shaped like an hourglass or a janggu shape is provided, but the shape is not limited thereto.

In Figure 3 (a), the bellows 200 is a first bellows 210 of an inverted trapezoidal cylindrical shape coupled to the upper surface 100, one surface is coupled to the first bellows 210 and the other surface is the lower surface The second bellows 220 and the second bellows 220 of the trapezoidal cylindrical shape coupled to the 300 are made of a magnetic material 221 disposed inside the upper end. As a modification, the lower surface 300 may be configured to be detachably attached as shown in (b) of FIG. 3 in order to use only as a general ball marker when putting. For example, a protrusion 222 is formed in the center of the lower surface 300 , and a groove corresponding to the position of the protrusion 222 is formed at the lower end of the second bellows 220 . When using the golf aiming device 10 , the lower surface 300 is locked and fixed to the second bellows 220, and when used only as a ball marker, the lower surface 300 is separated from the second bellows 220, and the lower surface 300 is turned over and the protrusion 222 is drawn on the grass of the green. Fix and mark

Here, the golf aiming device 10 of the present invention can be used regardless of whether the golfer is left-handed or right-handed, and can be more usefully used in foggy cloudy days or night golf games. For example, if a left-handed golfer is irradiated with a laser beam from the first light source 110 in a target direction, in the case of a right-handed golfer, the laser beam may be irradiated from the second light source 120 to a target direction, but for convenience of explanation, the first It will be described that a laser beam for a target direction is irradiated from the light source 110 and a laser beam for an address direction is irradiated from the second light source 120 .

Meanwhile, as shown in (a) of FIG. 4 , in order to arrive at the green 40 and putt, it is important to first measure the distance from the golf ball 20 to the hole cup 30 and check the direction. The golf aiming device 10 used as a ball marker may be placed at a position as close as possible to the rear of the golf ball 20 based on the hole cup 30 , and the golf ball 20 may be lifted and repositioned in the target direction to putt.

Here, since the golf aiming device 10 needs to be irradiated with a laser beam at a position higher than the diameter of the golf ball 20, it is implemented in the form of a ball marker whose height can be adjusted. If the laser beam irradiated in the target direction is lower than the golf ball, the golf ball is blocked and the laser beam is not displayed on the floor in front of the golf ball, so it cannot be compared with the putting line drawn in the golfer's head. Therefore, when the bellows 200 is reduced to use the golf aiming device 10 according to the present invention as a portable or simple ball marker ( FIG. 2 ), for example, it has a thickness of 15 mm or less, and expands the bellows 200 . The lower surface (Fig. 3) is 45mm or more, which is higher than the golf ball diameter (the official diameter is 42.67mm or more).

In addition, in order to irradiate the laser beam from a position higher than the golf ball to the floor surface in the target direction during putting, the first light source 110 causes the LED and the straight laser beam irradiated from the LED to be irradiated to the floor surface and the length of the irradiation As shown in FIG. 5(c), in order to maximize It contains a special lens in the form of a combined It is schematic that the laser beam irradiated through the special lens applied to the first light source 110 is maximally irradiated to the bottom surface in the target direction, such as a hole cup or flagpole, from a position higher than a golf ball as shown in FIG. 4(b). is indicated by Like the first light source 110, the second light source 120 also includes an LED and a special lens (FIG. 5(c)).

In Figure 4, if the target point on the putting line drawn in the head is the hole cup 30, when the golfer expands the bellows 200 of the golf aiming device, the straightness of the straightness that automatically passes through the special lens of the first light source 110 The laser beam 111 and the laser beam 112 toward the bottom surface in the target direction are irradiated in the direction of the hole cup 30 . In this case, when the green 40 is not flat and the slope is inclined, it is possible to intuitively check the inclination of the green in advance by recognizing that the laser beam 112 to the floor surface in the target direction does not reach the target point. Next, the golf aiming device 10 is positioned so that the laser beam is irradiated to the target point on the extension line or extension line of the putting line. And the golf ball 20 is positioned directly in front of the golf aiming device 10 so that the laser beam is parallel to the guideline marked on the ball or the manufacturer's identification mark (trade name, etc.) displayed in the horizontal direction on the surface of the ball .

The golfer has a laser beam of the first light source 110 that is irradiated to a target point in parallel with the guideline of the surface of the golf ball 20 or the manufacturer's identification mark, and the laser beam of the second light source 120 that is 90 degrees different from this. Place both feet with reference to and remove the golf aiming device 10 of the present invention without additional positional movement and then make a putting shot. When the bellows 200 of the removed golf aiming device 10 is reduced, the laser beam is automatically turned off, and the golf aiming device 10 is attached to a clip-type marker holder to conveniently carry and can be kept

As such, even a beginner golfer can easily put the ball in the direction of the hole cup of the putting line set in his head in advance, and has the advantage of reducing the number of strokes by reducing putting mistakes.

In addition, unlike in putting, in tee shots and fairway shots, it is not necessary to position the ball directly behind the ball, so as shown in FIG. It can be addressed by referring to the laser beam irradiated in the address direction perpendicular to the target direction, so that it is possible to hit the target in a more accurate target direction. At this time, by referring to the laser beam, which is visually shown long as the bottom surface in the target direction, considering the pitch change that may vary depending on the golfer's hitting characteristics (hook, slice, draw, fade shot) or the condition of the ground (uphill, downhill), You can intuitively check and adjust the target direction.

6 is a block diagram according to an embodiment of the present invention. In FIG. 6, when the bellows 200 is extended by pulling the upper surface 100 and the lower surface 200 to each other before making a tee shot, fairway shot, and putting shot, the separation sensor unit 130 is a second bellows ( Recognizing that the magnetic body 221 installed inside the upper end of 220 is separated from each other, a separation detection signal is output to the power supply control unit 140 . The power supply control unit 140 supplies power supplied from the power supply unit 150 to the first light source 110 and the second light source 120 in association with the separation detection signal. For example, the separation sensor unit 130 may be configured as a Hall sensor, and the power supply control unit 140 may be configured as a switching circuit. When power is supplied through the battery 153 and the power supply control unit 140 , the laser beam is irradiated from the first light source 110 to the front target direction, and from the second light source 120 in the address direction perpendicular to the target direction. A laser beam is irradiated.

At this time, each of the first and second light sources 110 and 120 includes an LED for irradiating a laser beam, and a special lens (FIG. , when the straight-through laser beam output from the LED passes through a special lens, the straight-forward laser beam is irradiated onto the floor surface in the forward direction.

The power supply unit 150 may be implemented as a general primary battery, but in the present invention, a rechargeable battery is used to be recharged by wireless charging by a widely used wireless charger. Even if used in a golf game on a rainy day, the present invention is waterproof and can reduce the hassle of replacing the battery. In addition, without arranging an external power on/off switch or button, the magnetic body 221 of the bellows 200 is spaced apart to operate the first and second power sources 110 and 120 according to the change in the height of the bellows 200 . It is possible to reduce the malfunction of the circuit by designing a dust-proof design that prevents dust from entering the PCB circuit from the outside.

In the charging mode, the wireless charging receiving module 151 receives power by magnetic induction from the transmitting module of the wireless charger (not shown in the drawing), converts it into battery charging power, and supplies it to the battery charging unit 152 . The battery charging unit 152 charges the rechargeable battery 153 according to battery charging power. The charging state display unit 154 may check the charging state of the battery 153 through the battery charging unit 152 to display whether the battery is being charged normally or is malfunctioning with an LED color, and may also display the remaining charge. For example, the LED turns blue during normal charging, turns red when an error occurs during charging, and is not displayed in standby mode. The remaining amount of charge can be displayed by the number of LEDs lit.

During a golf game, in the golf aiming device 10 according to the present invention, the power charged in the battery 153 is constantly supplied to the separation sensor unit 130 and the power supply control unit 140 , and the bellows unit 200 . When the magnetic material 221 is separated by extending to supply
