[Background technology]

Generally, in golf games, individual practice is indispensable in order to improve a golfer's score. It is necessary for each club to practice consistent swings for each club. Golfers who can swing in a good form for each club will be able to score well in the competition. Constant practice for a consistent swing is important for all clubs, but it is clear that it is most important for putters. In Pattin in a golf game, a ball travels over a green toward an object and enters a hole or a cup. Needless to say, it is extremely important for each person to practice putting so that they can adapt to the conditions and hazards encountered on various golf courses.

A variety of golf practice devices for enabling such putting practice have been disclosed. For example, Korean Utility Model Bulletin No. 92-7402 describes a golf practice device that includes a basket for storing golf balls and allows not only putting practice but also approach shots. However, in such a golf practice device, there is a problem that the slope of the slope is uniformly limited and the slope and curved surface most suitable for the actual green cannot be formed. In other words, although there are various forms of ups and downs on the actual green, following ups and downs, hills and curved surfaces, it is difficult to practice golf while creating such an environment with the prior art golf training device. Become.

Recently, a golf practice device capable of adjusting the slope inclination is being developed,
Such a golf practice device is constructed by screw assembly, and the process of adjusting the inclination of the slope is complicated, and it cannot be used for a long time due to corrosion and wear, and it is made of metal. It was inconvenient.

Furthermore, in the golf practice device according to the prior art, after checking by putting the golf ball into the hole cup after putting by the golfer, the head is raised and visually confirmed. There was a problem that the golfer's putting posture was lost due to head-up.

Therefore, in recent years, devices and the like have been developed for preventing the posture of a golfer from collapsing due to head-up. For example, in Korean Patent Publication No. 95-86,
A putting training machine is described. Such a putting practice machine is provided with a switching unit, a lamp and a speaker. When the golf ball does not enter the hole cup, the lamp is turned on and the speaker outputs the sound. However, since such a putting practice machine has a structure including a hole cup, a golf ball drop path, a recovery path, and the like, there is a problem that the volume is increased and the weight is further increased.
In addition, when trying to practice putting by moving the place, there is the trouble of reassembling the entire training machine and then reassembling it.

As another example, Korean Utility Model Publication No. 97-60781 describes a putting practice machine that outputs a sound when a golf ball passes a guide hole when a golfer puts. Although such a putting training machine has a small volume and weight, unlike the actual green in which the hole cup is provided on the ground, in the state where the guide hole is arranged so as to project from the ground, A speed sensor is installed in the guide hole that functions as a hole cup, and when the golfer actually practices putting to detect whether the golf ball is passing, the visual guide provided by the guide hole of the putting practice machine. There is a problem that the physical effect is completely different from that of an actual hole cup, and thus, the putting practice machine cannot exert a great influence on the improvement of putting feeling.

Further, in the putting practice machine or the like according to the prior art, although a voice message emitted from the putting practice machine can be heard within a certain distance during putting practice, if the golfer deviates from the certain distance, the golfer gives a voice message. There was a problem that I could not listen properly and the putting practice machine could not fulfill its original function.

[Industrial availability]

According to the above-described technical configuration of the present invention, by selectively injecting air into the outer airbag or the inner airbag, the golf training apparatus can be inclined forward and backward, and / or leftward or rightward. Since it is possible to form a slope inclined to, it is possible to form a slope most suitable for the actual green slope condition. further,
By selectively injecting air into one or more specific airbags of the two or more internal airbags, it becomes possible to form a curved surface on the golf practice device. As a result, not only putting practice but also chipping practice can be performed by using the golf practice device according to the present invention having the external airbag and the internal airbag.

Further, in the present invention, the golf ball sensing unit or the switching unit is provided inside the hole cup member, and when the golf ball passes the upper portion of the hole cup member, the golf ball sensing signal is output to thereby output the speaker. More sound is output to inform the golfer that the golf ball has been hit correctly, so there is no need to check the direction of the ball after putting or chipping one by one. This prevents the golfer from heading up, so the golfer's golf ball can be prevented. The striking posture can be effectively calibrated.

Since the hole cup member can be fixed to an arbitrary position on the golf practice device and used while appropriately adjusting the angle of the slope using the external airbag and / or the internal airbag, various slope conditions, etc. It becomes possible to practice golf.

Furthermore, since the golf practice device according to the present invention can be made compact and lightweight,
Easy to carry and set up, golfers can practice putting anywhere anytime. Furthermore, in the golf practice device according to the present invention,
The effect of putting practice can be maximized by arranging the hole cup target part on the same plane as the actual hole cup, and it becomes possible to improve the feeling of putting practically.

Further, signals can be exchanged remotely with a hole cup member having a golf ball sensing unit for sensing a golf ball and a control body having a speaker for outputting a voice message being separated from each other. With such a configuration, the distance between the hole cup member and the control body and the distance between the hole cup member and the striking position can be set freely, which doubles the practice effect. The control body, which has a speaker for outputting a voice message in connection therewith, can be attached to the golfer's belt or placed in various positions on the green.

Further, when putting the golf ball while the control body is in the hitting position, when the golf ball passes through the hole cup member, the speed measuring unit of the control body displays the speed and distance of the golf ball on the display. The golfer can grasp the position of the golf ball without losing his posture, and can practice putting in a stable posture.
