In general, golf is a game of putting a golf ball into the hole with the shortest number of batters, and a person with a low number of batters till entering the hole wins the game.

Golf is a drive club that hits a long distance and then uses an iron to move it closer to the hole cup. When the golf ball is nearest to the hole cup, the putter is used to hit the golf ball and put it in the hole cup.

In the case of a novice golfer who is new to golf, the golf ball will fly off the hole when putting the golf ball in the wrong direction.

In addition, the misalignment of the green slope, the grass grain, and the deflection of the green, and the deviation from the ideal perpendicular to the putting line of the club face will cause the golf ball to deviate from the planned putting line, From reaching the hole cup.

In the case of a putting, the putting line to the hole cup is predicted by carefully observing the green inclination, the grass grain direction, the degree of warping of the green in the vicinity of the hole cup, and the distance and direction from the golf ball to the hole cup. Golf putters equipped with direction indicators and distance measuring means which can help to determine the direction and the distance are already on the market, There is a demand for a golf practice apparatus which can further improve putting ability of a novice golfer through a golf training apparatus capable of recognizing a starting point.

Using the above properties, the golf practice apparatus according to the present invention can be operated in three modes as two practice modes and field training modes.

At this time, it is preferable that the switch operation is performed only in a state in which the LED (Light Emitting Diode) is not lit, and the operation operation is prohibited at the time when the LED is operated.

The first practice mode of the golf practice apparatus is the practice mode using only the laser in the room. In the case of the putter practice, the sensor operation is stopped and the laser is turned on / off in the room with minimum power consumption. can do.

Further, according to the golf practice device of the present invention, the laser irradiation time of the LED light emitting part of the main body and the laser module can be operated differently according to the pressing time of the switch.

At this time, it is preferable to operate the switch only in a state in which there is no LED light.

For example, in Practice Mode 1, in the case of putter practice, it is possible to use it as a practice mode that uses only laser in the room, and the sensor that detects the direction does not work.

In this case, the switch press time is shorter than 1 second. If the switch is sensed, the LED operates for 2 seconds at maximum. Then, when the switch is released, the laser operates for 5 seconds. . After 5 seconds, the laser is turned off and the operation of the laser is stopped for 5 seconds. At this time, the LED emission part flashes red. After the 5 second wait time, all LEDs are turned off and switch input is enabled.

In other cases, in Practice Mode 2, in the environment similar to the field mode in the evening when the sun is weak, you can practice using the laser and the sensor indoors during the putting practice, and you can set the direction and practice through the sensor.

In Practice Mode 2, you can practice using laser on / off and direction sensor in the room with minimum power consumption. In practice mode 2, it is necessary to set the direction after setting it on the shaft of the golf club before use.

In Practice Mode 2, press the switch for 2 seconds or more while determining the direction, the LED of the LED will change from green to amber for 1 second and the laser will operate. If you release the switch at this time, you will be in practice mode 2.

In Practice Mode 2, the laser operates at low power and the direction is instantaneously set when the switch is released within 2 seconds.

After that, the laser is turned off and the LED emission part flashes yellow for 5 seconds, and the laser operates as soon as the determined direction and the position of the sensor reach 90 degrees. At this time, the LED of the LED light emitting portion turns green and is displayed for 2 seconds.

If it does not find 90 degrees in time, the function will automatically stop for 5 seconds, the LED and the laser will both turn off and the LED will flash for 5 seconds in red.

In another case, the field is used in field with strong sunlight. It is similar to the case of practice mode 2, but the laser emission is maximized.

Also, the field mode needs to be manipulated while setting the direction after mounting it on the shaft before use.

In the field mode, when the user presses the switch for more than 3 seconds, the LED of the LED flashes from green to yellow for 1 second and the laser operates.

If the switch is continuously pressed for 3 seconds or longer, the LED of the LED flashes in red.

When operating the golf practice device in the field mode, set the direction of the switch and store the value of the moment the switch is released, the laser is turned off, and the LED flashes a red flash for 5 seconds.

Also, when the LED emission part is flickering, the laser operates and the LED emission part changes to green when the temperature reaches 90 degrees.

Thereafter, the LED light emitting portion and the laser are operated for 2 seconds and all are turned off.

The golf practice implement of the present invention may be capable of operating in other modes besides practice modes 1, 2 and field mode.

As another example, the switch operation is operated differently. If the user presses the switch of the golf practice device, the LED emitting portion is displayed in green from yellow to yellow to red in LED for 2 seconds each.

Accordingly, the user can determine the used function mode according to the light emitting state of the LED, and when the use mode is determined, the laser and the LED operate after 1 second.

In addition, as in the case of Practice Mode 2 or Field Mode, the sensor and laser act for 5 seconds and can automatically store the last position value.

In such a case, the laser state must be maintained without any special operation, and the operation can be performed in the same manner as the operation in the practice mode 1, 2 and the field mode.
