Abstract

PURPOSE:To enable a user to be in an appropriate position using a golf training device in which the direction of the user's face and the positions of the user's eyes are reflected in a circular disk, by confirming whether or not a virtual line between the position of a golf ball and a target point coincides with a reference line using a laser beam. CONSTITUTION:To use this golf training device, first, a user has an operating body 23 and stands in an addressing position in front of the golf training device. When a target point M is determined, a power supply switch 25 is operated and while reflecting the user's face in a mirror plate 4 of a supporting member 2 through a circular disk 1, a motor switch 24 is operated. Thus, a motor 21 of a driving mechanism 20 is driven to turn the circular disk 1 and a displaying part 10. When the user judges that a virtual line Q between a golf ball in a center 10a and the target point M overlaps a linear member 12 along a reference line P, the motor 21 is stopped. Subsequently, a laser switch 34 is operated to radiate a laser beam. As a result, when the virtual line Q coincides with the reference line P, the laser beam reaches the target point M so that it is confirmed that the user's judgment is correct.

As shown in FIG. 4, the magnet 13 is fitted in the concave portion 7 of the mounting portion 6 and magnetically attached to the shaft body 5. Then, the ring portion 11 and the linear portion 12 are positioned on the disk 1. When the display portion 10 is placed on the disc 1, the linear portion 12 allows the reference line P passing through the center of the disc 1 to be recognized.

Reference numeral 20 denotes a drive mechanism for rotating the disk 1 at the time of starting and stopping and positioning the disk 1 at the time of stopping, which is driven by radio control. The drive mechanism 20 includes a motor 21 installed on the substrate 3 of the support 2 and capable of rotating in the forward and reverse directions,
A rubber roller 22 is provided on the rotation shaft of the motor 21 to contact the disk 1 to transmit the rotation of the motor 21 to the disk 1 to rotate the disk 1. When the disc 1 rotates, the disc 1 is separated from the end plate 4 and is made of a light material such as resin, so that the disc 1 rotates smoothly, and the power of the drive mechanism 20 is correspondingly increased. Since the number can be reduced, the device can be downsized.

Reference numeral 23 is an operating body which is operated by remote control to start and stop the drive mechanism 20. This operating body 23
Is due to so-called radio control operation in which a signal is transmitted wirelessly. The stop position for stopping the motor 21 and the motor 2

The laser light transmitter 30 includes a light transmitter main body 31 that has a built-in power source and sends or stops laser light based on a wireless on / off signal. Reference numeral 32 denotes a stand that holds the light transmitter main body 31 and can be placed on the disc 1. A friction mat 33 is attached to an installation surface of the disc 1. The laser transmitter 30 is placed on the linear portion 12 of the display unit 10 so that the optical axis passes through the reference line P. 34 is the laser transmitter 3
It is a wireless laser switch that turns on and off 0.
The operation body 23 is provided. The laser switch 34 turns on the laser transmitter 30 when the push button is pressed, and turns off when the push button is released.

Therefore, when the golf training apparatus according to this embodiment is used, it is carried out as follows. First, for example, as shown in FIGS. 1 and 5, the golf practice device is installed, for example, indoors. Further, the display unit 10 is placed on the disc 1. In this case, the magnet 1 provided at the center
3 fits into the recess 7 of the mounting portion 6 and is magnetically attached to the shaft body 5, so that the ring portion 11 and the linear portion 12 of the display portion 10 are formed into the disk 1.
Above, it becomes difficult to move and is positioned accurately. Also,
The laser transmitter 30 is placed on the linear portion 12 of the display unit 10 so that the optical axis passes through the reference line P. In FIG. 1, disk 1
It is placed so that the laser beam is emitted from the outer edge of the. In this case, since the friction mat 33 is provided on the installation surface of the stand 32 of the laser transmitter 30, it becomes difficult to move and the positioning is accurately performed. Moreover, some targets M are set. As the target M, for example, a standing board about the size of a business card is used, or the wall surface of a room is used.

In this state, the manipulator 23 is held in the hand, and the player stands in the address posture with the golf training device installed in front.
Then, one target M is determined, the power switch 25 of the operating body 23 is turned on, the face of the practitioner is projected through the disc 1 on the end plate 4 of the support body 2, and the motor switch 24 of the operating body 23 is set. By operating it, the motor 21 of the drive mechanism 20 is rotated in the forward and reverse directions to rotate the disk 1 and the display unit 10 to form an imaginary line Q that seems to be a line connecting the center portion 10a, which is the position of the golf ball B, and the target M. The linear portions 12 along the reference line P of the display unit 10 are made to overlap with each other, and the motor 21 is stopped at the point where it is determined that they overlap. When the disc 1 is rotated, the disc 1 is separate from the end plate 4 and is made of a light material such as resin, so that the disc 1 is rotated smoothly.

Next, the laser switch 34 of the operating body 23
Is operated to irradiate a laser beam. In this case, if the virtual line Q and the reference line P coincide with each other, the irradiation light follows the reference line P, so that the laser beam hits the target M and a light spot appears at the target M. This shows that the practitioner's judgment was correct. On the other hand, as shown in FIG. 5, when the imaginary line Q and the reference line P do not coincide with each other, the irradiation light is along the reference line P, so that the laser beam hits a point other than the target M and the light is radiated to this point. A point appears. This shows that the practitioner's judgment was incorrect. In this case, the end plate 4
By observing the orientation of the face and the position of the eyes reflected in (1), it is possible to know the positional relationship with respect to the reference line P and correct the posture with respect to the target M.

Then, again, as in the above, the operating body 23
The motor switch 24 is operated to rotate the motor 21 of the drive mechanism 20 in the forward and reverse directions to rotate the disk 1 and the display unit 10, and to connect a line connecting the central portion 10a which is the position of the golf ball B and the target M. The linear portion 12 along the reference line P of the display unit 10 is made to overlap the supposed virtual line Q, and the motor 21 is stopped at the point where it is determined that the lines are formed. In this state, the laser switch 34 of the operating body 23 is operated to irradiate a laser beam, and it is checked whether or not the laser beam hits the target M to know whether or not the practitioner's judgment is correct.

In this manner, the orientation of the face and the position of the eyes reflected on the end plate 4 are observed, the positional relationship with respect to the reference line P is known, and the posture with respect to the target M is corrected. By irradiating the laser beam, it is checked whether the correction is correct. Therefore, the correction of the posture can be confirmed by irradiating the laser beam, so that the posture can be sufficiently corrected by the end plate 4. Further, not only one target M but also the other targets M are performed in the same manner as above. In this case, the other target M can be aimed only by rotating the disc 1, and various distances and directions can be set.
Wide range of use.

Further, the golf training apparatus according to this embodiment is
You can use it in different ways. For example, as described above, the display unit 10
Is placed on the disk 1 and the laser transmitter 30 is not placed. In this state, hold the putter in your hand and swing along the reference line P. In this case, the orientation of the practitioner's face and the position of the eyes can be displayed on the end plate 4, so that the posture in which the player is swinging can be known, and for example, a check such as swinging without moving the head can be performed. Therefore, the posture can be corrected sufficiently.

As another example of usage, for example,
As shown in FIG. 6, the disc 1 is exposed without placing the display unit 10 on the disc 1, and the golf ball B is hit with a putter on the placing unit 6 by the putter. in this case,
It is possible to hit the golf ball B by taking addresses for the golf ball B in various directions. That is,
Since the outer edges of the disk 1 and the end plate 4 are circumferential, the conditions are the same regardless of which direction the golf ball B rolls when passing the outer edge, as compared with the case where the end plate 4 is formed in a rectangular shape.
Therefore, it is possible to hit the golf ball B in various directions under the same conditions. Further, in this case, if the display unit 10 is removed from the disc 1, there is no hindrance when hitting the golf ball B, and the conditions for rolling in various directions can be made the same. Further, only the face can be projected on the disk 1, and the direction and the line of sight of the face can be seen well. Furthermore, since the mirror plate 4 is covered with the disk 1 when hitting with a putter, the mirror surface 4a is less likely to be scratched and the mirror surface 4a is protected.

In the above embodiment, the position of the laser transmitter 30 is not the above-mentioned position, but the irradiation light is arranged so as to pass through the central portion 10a of the display unit 10, as shown in FIG. Is also good. Further, in the above embodiment, the display unit 1
0 is not limited to the above, for example,
As shown in FIG. 8, an arrow-shaped protrusion 40 may be provided on the outer edge of the disk 1 so that the reference line P connecting the center and the arrow 40 can be recognized. Further, the display unit 10 is shown in FIG.
As shown in FIG. 5, the line 41 may be directly drawn on the disc 1 and may be appropriately changed. Further, in the above embodiment, the disc 1 is made of a transparent sheet, but the present invention is not necessarily limited to this, and the surface may be a plate having a mirror surface, and may be appropriately changed. In addition, it goes without saying that the remote control of the drive mechanism 20 is not limited to the above-described wireless and may be wired.

[0029]

As described above, according to the golf training apparatus of the present invention, it is determined whether the virtual line, which is considered to be the line connecting the golf ball position and the target, exactly matches the reference line. It can be confirmed by irradiating the laser light of the light transmitter.
Therefore, it is possible to improve the correction accuracy when the orientation of the face, the position of the eyes, and the like with respect to the reference line when hitting the golf ball is projected on the disc to correct the posture. Further, there is an effect that training for catching the goal can be performed.

Further, when the disk is formed of a transparent sheet and the support body is provided with a mirror plate having a mirror surface that reflects the face of the practitioner through the disk, the rotating part and the mirror surface can be separated. Therefore, the mirror surface of the mirror plate is less likely to be scratched, and the mirror surface can be protected. In addition, since the rotating portion and the mirror surface are separated, the disk can be made of a light material such as a resin so that the disk can be smoothly rotated, and the power of the drive mechanism can be reduced, so that the device can be downsized. .

Further, when the end plate is formed in a disk shape having the same central axis as the disk, since the outer edge of the end plate is circumferential,
Compared to the case where the end plate is formed in a rectangular shape or the like, when the golf ball is placed on the mounting portion and hits the golf ball and the golf ball passes the outer edge, the conditions are the same regardless of the direction in which the golf ball rolls. It is possible to hit the golf ball in various directions in the same manner.

Furthermore, the display portion is formed of a sheet that can be placed on a disc, and has a ring portion that has the same central axis as the disc and a linear portion that is installed on the ring portion and that follows the reference line. In the case where the golf ball is equipped with the display unit, if the display unit is removed from the disk, there is no hindrance when hitting the golf ball, and the conditions for rolling in various directions can be made the same. In addition, only the face can be projected on the disc, and the orientation of the face and the position of the eyes can be seen well.

Further, the center of the disk is rotatably supported by a shaft which is erected on a support and penetrates through the center of the disk, and the tip of the shaft is expanded into a circular shape to press the disk and to place it. When the portion is formed by the tip surface of the shaft body and the center of the tip surface is formed in a concave shape, the shaft body is fixed and the tip surface is formed in a concave shape. Is certain,
Positioning can be ensured.

Further, the drive mechanism is provided with a motor installed on the support and capable of rotating in the forward and reverse directions, and a roller provided on the rotating shaft of the motor and abutting against the disk to transmit the rotation of the motor to the disk. When configured, the drive can be performed with a relatively simple structure, and the device can be downsized.

When the laser transmitter is provided with the transmitter main body and the stand which holds the transmitter main body and can be mounted on the disk, the laser transmitter can be detached. In this way, you can move the putter without taking any troubles, and you can hit the golf ball with the putter and roll it in various directions.

Further, when a friction mat is provided on the installation surface of the stand of the laser transmitter for the disc, the laser transmitter can be made hard to move when the disc rotates, so that the irradiation light surely passes through the reference line. can do.
