Frame 110 may be made of a metallic material or synthetic resin material, and has a structure that can be fixed to the artificial grass bottom of the golf driving range or the natural grass bottom of the golf course.

Frame 110 serves to fix the horizontal axis 120, and to secure the entire exercise device to the floor or other equipment (for example, golf driving range facilities, such as automatic golf ball supply).

The horizontal shaft 120 is installed to be coupled to the frame 110 to move up and down. Looking at the connection between the horizontal axis 120 and the frame 110 in detail, both sides of the frame 110 is provided with side plates 112 formed in parallel to each other, the side plate 112 is the lifting guide 114 in the vertical direction Are each formed. Both ends of the horizontal shaft 120 are coupled to the elevating guide 114 to provide a structure in which the horizontal shaft 120 is lifted with respect to the frame 110 and fixed at a predetermined position. The elevating guide 114 may be formed in a slit groove shape as shown in the drawing.

Both ends of the horizontal shaft 120 is disposed in the elevating guide 114, and is connected to the fixing means 122. The fixing means 122 is screwed to the horizontal shaft 120 through the elevating guide 114, by adjusting the height of the horizontal shaft 120 by releasing the fixing means 122, tighten the fixing means 122 The horizontal axis 120 can be fixed by zooming.

Since the sensor main body 130 is fixed to the horizontal axis 120, the height of the sensor main body 120 may be adjusted by adjusting the height of the horizontal axis 120. In addition, the sensor body 130 is installed to be movable in the horizontal direction along the horizontal axis (120). Therefore, by adjusting the height of the horizontal axis 120, and by adjusting the position of the sensor body 130 on the horizontal axis 120, it is possible to adjust the height and the horizontal position of the sensor body 130.

Like the frame 110, the horizontal shaft 120 may be made of metal or synthetic resin, and may include a ruler on the surface of the horizontal shaft 120 or the surface of the frame 110. When the ruler is provided on the surface of the horizontal axis 120 and the frame 110, the position of the sensor body 130 can be adjusted more accurately. In addition, when provided with a ruler, the user remembers the height and the horizontal position that was placed when he practiced and always brings the comfortable effect of positioning the sensor body 130 in a constant position.

The sensor body 130 detects whether the head of the golf club has passed a predetermined position and plays a role of informing the exerciser.

The sensor body 130 has a non-contact sensor unit 135 for detecting whether the golf club head passes, a pointer unit 137 for irradiating light to the detection area of the non-contact sensor unit 135, and the non-contact sensor unit ( In step 135, the golf club head includes a signal generation unit 133 for generating a designated notification signal.

The signal generator 133 includes a speaker 132 for generating a sound (voice or sound) signal and a notification lamp 134 for generating a lighting signal using light. In the illustrated embodiment, the signal generator 133 includes both the notification lamp 134 and the speaker 132, but may include only one of the notification lamp 134 and the speaker 132.

The non-contact sensor unit 135 detects whether the object passes through the sensing area by irradiating invisible light, sound waves, and the like to the sensing area, and an ultrasonic sensor, an infrared sensor, and a laser sensor may be used.

Detecting whether the golf club head passes through the non-contact sensor as described above, does not interfere with the impact of the exerciser at all, and also has the advantage that the sensor body 130 is not moved by the impact delivered when the hit. In other words, it is difficult to identify which point is detected.

The present invention is characterized in that it comprises a pointer unit 137 for irradiating light to the detection area of the non-contact sensor in order to eliminate the inconvenience when using the non-contact sensor.

The pointer unit 137 is disposed adjacent to the non-contact sensor unit 135 and is installed to be irradiated in the same direction as the light or sound wave emitted by the non-contact sensor unit 135 for detection. Therefore, the exerciser can easily check which area is detected by the non-contact sensor unit 135 by checking the point indicated by the pointer unit 137. As the pointer portion 137, it is preferable to use a laser pointer having excellent straightness and good visibility outdoors.

When the head of the golf club passes through the detection area of the non-contact sensor unit 135, the speaker 132 and the notification lamp 134 of the signal generator 133 is operated to inform the exerciser that the swing is made correctly. .

In the speaker 132 generating a voice or sound signal, an electronic sound such as 'ding dong' may be reproduced, or a recorded voice such as "okay" may be reproduced.

The notification lamp 136, which generates a light signal by light, may be turned off while being turned off, and when it is detected that the golf club head passes through the non-contact sensor unit 135, it may be turned on for a few seconds and then turned off. In the turned on state, the red light is maintained, but when the golf club head is detected, the light is changed to the green color as if the golf club head is detected.

The sensor body 130 has a built-in power source such as a battery, a secondary battery, it is preferable that the device used in the indoor practice room is formed to be connected to a separate adapter.

In the illustrated embodiment, although the sensor body 130 is provided with one, the sensor body 130 may be provided with two sensor bodies 130 to detect swing trajectories both before and after the golf ball.

3 to 5 is a conceptual diagram showing a state of use of the non-contact golf swing training apparatus according to the present invention.

As shown, after the exerciser adjusts and positions the position of the sensor main body 130 so that the sensing area of the non-contact sensor unit 135 is positioned on the swing trajectory to be practiced based on the golf ball B, When the swing practice is performed while hitting the golf ball B, the golf club head H passes through the detection area of the non-contact sensor unit 135 when the correct swing is made. Signals or alerts are generated so that the practitioner knows immediately whether the correct swing was made without disturbing the ball's concentration and posture.

Referring to FIG. 5, the non-contact sensor unit 135 detects the passage of a region indicated by a dotted line by generating light or ultrasonic waves that are not easily visible as indicated by a dotted line, and the pointer unit 137 is a non-contact sensor unit. Parallel to the 135, the visible light is fired. Since the non-contact sensor unit 135 and the pointer unit 137 are disposed adjacent to each other, the light emitted from the pointer unit 137 substantially matches the detection area of the non-contact sensor unit 135.

Referring to FIG. 4, it can be seen that light rays emitted from the pointer unit 137 form an acute angle θ with the ground. The ray of light emitted from the pointer unit 137 is parallel to the sensing area of the non-contact sensor unit 135, and the non-contact sensor unit 135 also forms an acute angle θ same as that of the ground. At this time. It is preferable that the angle formed by the sensing area of the non-contact sensor unit 135 with the ground is in the range of 5 to 45 degrees. If the angle formed with the ground is too small, it may be detected until the passage of the exerciser's foot or another object. If the angle is greater than 45 degrees, the sensor body 130 is too close to the trajectory of the golf club head. There is a risk of hitting the swing practice device with the club head (H).

According to the present invention, the sensor body 130 may be disposed at a desired position, and thus may be utilized for posture correction in various manners.

First, as shown in FIG. 3, a case of using the take away posture correction will be described.

Normally, the head of the golf club should be pulled back about 10cm lower, so that the head does not turn back inside, so that the club is not pulled inside the body during the back swing or the golf club head does not open or close. .

In the case of performing the take away exercise, the non-contact golf swing exercise device according to the present invention, the non-contact sensor unit 135 detects the area, the exerciser places the desired length behind the golf ball B, where the laser pointer is located. In the swing direction after setting the part that is in direct line with the direction of the target to be lowered in the swing direction, when the golf club head (H) passes the detection area, the notification lamp and the speaker is activated to take the track of the golf club at take away You will immediately know whether the correctness is correct.

Next, look at the case of trying to correct the impact (impact) and release (release) position.

Golf swings are generally divided into upper blow, side blow and down blow depending on the impact angle. The trajectory through which the head of the golf club passes varies according to each swing. Using the golf swing practice apparatus according to the present invention, the detection area of the non-contact sensor unit 135 is set up to about 10 cm in front of the ball for each swing. If you practice the swing, the speaker and notification lamp will be activated whenever the golf club head passes through the detection area, so you can see immediately whether the correct swing was made.

In particular, in the case of down blow, it is common to determine whether the swing is good by looking at the divert of the grass after impact on the field. Using the golf swing exercise device according to the present invention, the sensor body is placed close to the ground and the laser If you set the place where the pointer points to the track where the golf club passes about 10cm, and then practice swinging, the club head passes through the detection area of the non-contact sensor in real time when it hits the grass and releases normally after impact. The loudspeaker and the alarm lamp will be activated so that you can immediately see if the correct swing has been made.
