Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf swing practice tool. More specifically, the practice tool allows a trainee to visually check the reflection of light from a reflecting surface provided on the practice tool. Regarding the improvement and correction of swing.

[0002]

2. Description of the Related Art Conventionally, when practicing a golf swing, the swing is practiced by swinging a ball using an actual golf club or hitting an actual ball. The purpose of practicing golf swing is to acquire the correct swing. To check the correctness of this swing, hold the golf club actually used, swing in front of a large mirror, see the swing reflected in the mirror, check the correctness of your swing, Or, under the present circumstances, the swing is corrected while having others see the swing and point out the problems of the swing. Alternatively, the swing is recorded by a video camera, and then the swing is checked by reproducing the recording.

[0003]

However, in the conventional practice of golf swing, it is judged whether or not the swing is properly performed, even if the player simply makes a swing or does a ball hitting practice in the practice field. It's very difficult to do. Even if you practice practicing in front of a mirror, you cannot correct the position of your head or face when you hit the ball, because your line of sight was toward the mirror. Therefore, in order to practice correct swing and correct the swing, the teacher had to correct the swing while checking the swing. Therefore, it is an object of the present invention to provide a golf swing practice tool that can learn the correct golf swing by one person and can correct the swing alone.

Especially for beginners of golf, such as trainers who have yet to complete golf swing, the aim is to acquire the correct golf swing. The task is to provide a golf swing that is naturally correct by repeating swing practice with practice equipment. It should be noted that the golf swing has a correct relationship such as the distance between the golfer's head (eyes) and the club head, the angle of the club head face, and the inclination of the shaft with respect to the rotation axis of the swing at the moment of address and impact. Only then can the correct swing be performed. By using the training tool according to the present invention to perform swing, it is possible to help correct these relationships and to learn the correct swing.

[0005]

In order to solve the above problems, a first aspect of the present invention is a golf club, or
The golf swing practitioner is provided with a mounting portion that can be detachably or fixedly mounted on a swing practice rod and a reflecting member attached to the mounting portion. The reflecting member has at least one reflecting surface. The light reflected from the reflecting surface of the reflecting member can enter the practitioner's eyes when performing the swing exercise. A second aspect of the present invention is the same as the first aspect of the present invention, in which the reflecting member is attached to the attaching portion so that the angle of the reflecting surface can be freely changed. According to these inventions, the practitioner, in the posture of the correct address, performs natural swing or actual ball striking practice with light rays such as natural light or light from lighting equipment entering the eyes of the reflection surface of the reflection member. Then practice the swing so that you can visually check the light reflected from the reflective surface from the moment of impact to the moment after that. The state where the reflected light can be confirmed is the case where the correct swing is performed, and the case where the reflected light cannot be visually confirmed is the case where the correct swing is not performed.

According to a third aspect of the present invention, a reflecting member is attached to the tip portion of a swing practice rod, a plurality of reflecting surfaces are provided on the upper surface of the reflecting member, and the inclination angles of the plurality of reflecting surfaces are respectively set. They are different from each other. As a result, the practitioner makes a posture at the correct address, and in this state, the stick is appropriately rotated about the stick, and the reflected light from the reflecting surface of the reflecting member attached to the tip of the stick is reflected in his or her eyes. Select one of the reflective surfaces so that it comes in,
Set its position. In this state, practicing practicing swing is performed, and practicing practicing is repeated so that the reflected light from the reflecting surface is incident on one's eye. When the practitioner can visually confirm the reflected light, it means that the correct swing is being performed, and the case where the reflected light cannot be confirmed is the case where the correct swing is not performed.
In this practice tool as well as the practice tool of the first invention, the light reflected from the reflecting surface of the reflecting member becomes an afterimage only from the moment of impact of the swing to the moment after that, and is practiced in a band shape. It remains in the eye of the person.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The accompanying drawings all illustrate embodiments of the present invention. FIG. 1 is an overall perspective view of a training tool 1 according to the present invention attached to a club 20 of an iron. The practice tool 1 is used by being attached to the shaft 22 slightly above the base of the head 21 of the club 20. The practice tool 1 is the shaft 22 of the club 20.
A reflection surface 4 is formed on the surface of the reflection member 3. Reflective member 3
Is attached to the mounting portion 2 and is formed so that the direction of the reflecting surface 4 can be freely changed.

More specifically, the mounting portion 2 is formed of a synthetic resin clip, and is mounted on the shaft 22 so as to sandwich the shaft 22. A connecting member 10 having a substantially U-shaped cross section is screwed to an extension of one of the grip portions 6 of the clip with a screw 11, and a plate-like reflecting member 3 having an L-shaped root is attached to the connecting member 10. It is screwed by the screw 12. As a result, the practice tool 1 is detachably attached to the shaft 22 of the club 20, the reflecting member 3 and the connecting member 10 can be rotated about the axis of the screw 11, and the axis of the screw 12 is centered. Since only the reflection member 3 can be rotated, the direction of the reflection surface 4 of the reflection member 3 can be freely changed. The clip as the mounting portion 2 can be made of various materials such as metal other than synthetic resin.

FIG. 2 shows a training tool according to the present invention, in which (A) is a plan view and (B) is a left side view. The mounting portion 2 is composed of a clip, and has a holding portion 13, 13 at a tip end portion thereof, and a grip portion 6 extending from each holding portion 13 downward in the drawing is provided. The sandwiching portions 13, 13 are constantly urged by the leaf spring 16 with a strong force in the direction in which the tips of the sandwiching portions 13 contact each other. Therefore, the tips of the holding portions 13 can be opened only by applying a force that brings the holding portions 6 closer to each other.

An extension portion 14 that extends further downward from one of the knob portions 6 is provided, and a connecting member 10 having a U-shaped cross section is combined so as to sandwich the extension portion 14 and screwed by a screw 11. On the other hand, the reflecting member 3 is formed of a plate-shaped member, and the surface shown in FIG. 2 (A) is the reflecting surface 4. A bent portion 15 bent substantially at a right angle is formed on the base side of the reflection member 3, that is, the end side joined to the connecting member 10, and the bent portion 15 is screwed by the screw 12.

With the above structure, the connecting member 10 can be rotated about the axis of the screw 11 by first loosening the screw 11, so that the reflecting member 3 is also screwed with the rotating of the connecting member 10. The reflecting surface 4 can also rotate by rotating about the axis of 11. Also, the screw 12
By loosening, the reflecting member 3 can be rotated about the axis of the screw 12, and at the same time, the reflecting surface 4 can also be rotated about the axis of the screw 12.
Thereby, the direction of the reflecting surface 4 of the reflecting member 3 can be freely changed. The shape of the reflecting surface 4 can be freely designed, but in this embodiment, the tip portion is wide and the root portion is narrow, and the right side edge in FIG. are doing. The right side edge is formed in a substantially straight line so that the right side edge can be arranged substantially parallel to the line of the sole of the club head when the practice tool 1 is attached to the shaft of the golf club. This is because.

A method of using the practice tool 1 will be described below with reference to FIG. First, the both grip portions 6 of the mounting portion 2 of the practice tool 1 are pressed with fingers to open both the gripping portions 13, and the shaft 22 of the club 20 is clamped by the both gripping portions 13, so that the practice tool 1 is attached to the shaft 22. Install. The mounting position is slightly above the head 21. Next, the grip portion of the club 20 is grasped to take a correct stance and take a correct address posture. In this case, a swing practice of actually hitting a ball may be performed, or a practice of only swinging may be performed.

In the attitude of this address, the reflecting member 3
The angle of the reflecting surface 4 is appropriately changed and adjusted so that the light L reflected from the reflecting surface 4 can enter the eyes. In particular,
Shaft 22 at the correct address
And the angle of the face of the head 21 are not changed, and the angle of the reflecting surface 4 is appropriately changed to adjust the reflected light to enter the eyes. In this way, when the posture of the correct address is taken, the reflected light from the reflector 4 enters the eyes. The reflected light may be natural light or indoor fluorescent lamps. At this time, the left side edge 18 of the reflecting surface 4 is adjusted to be substantially parallel to the sole 19 of the head 21, and the face of the sole 19 is visible. This makes it convenient to practice the swing by actually hitting the ball.

After adjusting the reflecting surface 4 in this manner, the practitioner swings the club 20 up from the address posture to shift to the back swing, swings back to the top state, and starts swinging. Start swing, enter down swing, and at impact (ball hitting point),
The light reflected from the reflecting surface 4 of the practice tool 1 according to the present invention must be sure to enter the eyes. In this case, the confirmation position of the reflected light is the moment of impact, and the incident state of the reflected light is the correct impact state. Further, the afterimage can visually confirm the trajectory of the golf head after impact. The afterimage of the reflected light after hitting the ball is about 20
For a length of about 30 to 30 centimeters,
It's as if you're pulling a belt.

In this way, when the light enters the eye at the moment of impact and the afterimage remains like a band and becomes a straight line toward the target point, the correct swing is obtained,
The state of outside and inside out can also be confirmed by the afterimage. As described above, in the case of correct swing, the ball is hit in the addressed state, the angle of the face of the head 21 is also in the address state, and the practitioner's line of sight is also in the direction in which the reflected light is incident. It is confirmed that they are not up.

On the other hand, a practitioner whose reflected light from the reflecting surface 4 does not enter the eyes, that is, a practitioner who cannot visually confirm the reflected light, has the following defects as the swing. . If the grip has a defect at the time of impact, that is, if there is a wristwork cock, hinge, rotation, or the like, the head 21 does not face the correct direction. Even if there are inconveniences such as hand turning, swinging delay, club face opening, head position, head trajectory, head up, etc. at the time of downhill, and inconvenience of turning back the top, practice reflected light Does not enter the eyes of the person. Furthermore, flexion and extension of the right arm and elbow, which should not change,
The reflected light does not enter even when there is a movement of the weight, that is, a so-called left leg wall or the like.

At first, the practice starts from the half swing, and when the reflected light enters the eyes on the front side from the moment of impact, the head 21 is faster than the wrist, or the club face is opened. If the reflected light enters the eye after the moment of impact, it is possible that the head is delayed or the grip is fogged. In the case of full swing, practice the swing while visually confirming that the afterimage of the reflected light is as long as possible by 20 to 30 cm from the moment of impact.

FIG. 3 shows another embodiment of the practice tool according to the present invention, in which (A) is a plan view and (B) is an enlarged left side view. In this practice tool 30, the mounting portion 2 does not consist of the clip according to the above-described embodiment, but by rotating the screw 31, the spacing between the sandwiching portions 13, 13 can be freely widened and narrowed. , 13 pinch the club shaft,
0 can be attached and fixed to the club shaft. The inclination angle of the reflection surface 4 of the reflection member 3 can be changed by loosening or tightening the screw 32.

That is, a coil spring 33 is built in on the base side (lower side in the figure) of the mounting portion 2, and the coil spring 33 always biases the bent portion 15 of the reflecting member 3 downward in the figure. Is in a state. A narrow folded-back portion 35 is provided at the upper end of the bent portion 15 of the reflection member 3, and the folded-back portion 35 is provided at the base of the mounting portion 2 in the left-right direction in FIG. 3 (A). It fits in the elongated groove 36. Therefore, by loosening the screw 32, the tip of the reflecting surface 4 can be moved in the direction of arrow P in FIG. 3B by the action of the coil spring 33 with the folded-back portion 35 serving as a fulcrum.

The reflecting surface 4 can also be rotated about the axis of the screw 32. This is because the width of the folded-back portion 35 is narrowed and the elongated groove 36 into which the folded-back portion 35 is fitted is formed so that the tip of the folded-back portion 35 can be freely moved in the elongated groove 36. Is. In this way, the reflecting member 3 can appropriately change the inclination angle of the reflecting surface 4. In FIG. 3, the attached golf shaft 22 and the reflecting surface 4 have a substantially right-angled positional relationship. However, this positional relationship can be appropriately changed and implemented. It is also possible to form an obtuse angle of 90 degrees or more.

4 and 5 show still another embodiment of the training tool according to the present invention, FIG. 4 is an overall perspective view thereof, and FIG. 5 is a reflection attached to the tip portion thereof. It is an expansion perspective view of the part of a member. The practice tool 40 includes a rod 41 and a reflecting member 42 fixed to one end of the rod 41, and a grip 43 is provided at the other end of the rod 41. The rod 41 is formed to have a length shorter than that of a normal golf club, and the grip 43 formed at the end portion and the thickness of the rod 41 are formed in substantially the same manner as a normal golf club.

The reflecting member 42 has a cylindrical shape,
It is fixed to the end of the rod 41 opposite to the grip 43. The material of the reflecting member 42 may be rubber or metal. When the reflecting member 42 is made of metal, it is preferable to form a hollow central portion in consideration of its weight. On the upper surface of the reflecting member 42, four reflecting surfaces 45 are radially formed around the rod body 41. A non-reflective surface 46 (a portion shaded in FIG. 4) that does not reflect is formed between the reflecting surfaces 45.
The respective reflecting surfaces 45 differ in angle a with respect to the rod 41 by about 2 degrees. This makes it possible for the reflected light reflected from the reflecting surface 45 to appropriately enter the eyes of the practitioner in response to incident light entering from various angles. The angle a of each reflecting surface 45 with respect to the rod 41 is not only different by about 2 degrees as described above, but the different angle can be appropriately changed as necessary.

When practicing a golf swing using the practice tool 40, the following procedure is performed. First, the practitioner
Take the stance according to the golf club such as wood or iron, and take the correct address posture. In this case,
The reflecting member 42 at the tip of the practice tool 40 is in a state of floating in the hollow. At this time, the rod 41 is rotated and adjusted so that the reflected light L enters the eyes from one of the reflecting surfaces 45 provided on the upper surface of the reflecting member 42. That is, the reflected light may be natural light or light from an indoor lighting fixture,
The incident angle of the light is variously different, and the rod body is appropriately adapted to the angle of the incident light so that the incident light reflects on the reflecting surface 45 and enters the eyes of the practitioner in the addressing posture. While rotating 41, one reflecting surface 45 is selected and the reflecting surface 45 is positioned.

By rotating the rod 41 about the rod 41, the angle of each reflecting surface 45 with the rod 41 is different by about 2 degrees. Even if the incident light is oblique or lateral, and the incident angle with respect to the horizontal plane is different, by rotating the rod 41, the incident light in various directions and at various angles can be obtained. The reflected light can enter the practitioner's eyes. In some cases, the position of the stance is changed in consideration of the direction of the incident light, that is, the body direction is changed so that the reflected light from the reflecting surface enters the practitioner's eyes. In this state, the practitioner repeats the swing practice so that the light enters the eyes at the moment of impact. The incident of the reflected light continues for a short period of time from the moment of impact, and remains as a residual image in a belt-like manner to the practitioner. When the band-like afterimage is linear toward the target point, the swing is correct, and as described above, the inside-out and inside-out states can be confirmed by the afterimage. If the reflected light cannot be confirmed at the moment of impact, correct swing is not being performed.

The various embodiments have been described above.
In the present invention, the form can be changed as follows. In the embodiment shown in FIGS. 1 to 3, the practice tool may be a golf swing practice tool attached to a rod-shaped rod body not provided with a club head, instead of an actual golf club. . Mounting part 2
The shape of is completely free, as long as the reflecting surface of the reflecting member does not vibrate or the angle of the reflecting surface does not change even if swinging, the reflecting member 3 can be firmly fixed to the golf shaft. Good. Further, the attachment portion 2 may not be detachably attached to the golf club or the like as in the above embodiment, but may be fixedly attachable to the shaft. For example, the mounting portion may be made of metal and welded directly to the shaft of a golf club or the like.

The connecting member 10 is not particularly required in the embodiment shown in FIG. 3, but in the embodiment shown in FIGS. 1 and 2, the connecting member 10 can have any shape. The present invention can be implemented without the U-shaped cross section as in the above embodiment, and may have the L-shaped cross section.
A fastening screw may be attached to the connecting member to connect the mounting portion 2 and the reflecting member 3 to each other, and the axial direction of the screw may be crossed. Screw 11, 12
Can also use various things, for example, thumbscrew,
Various fasteners such as bolts and nuts, screws and wing nuts can be used. The size and shape of the reflecting member 3 can be freely designed, and the reflecting member 3 can be implemented without forming one side edge of the reflecting surface 4 into a substantially linear shape. What is important is that the angle of the reflecting surface 4 of the reflecting member 3 is appropriately adjusted so that the light reflected from the reflecting surface 3 may enter the practitioner's eyes.
Need only be attached to the attachment portion 2.

In the embodiment shown in FIGS. 4 and 5, the length of the rod 41 can be freely designed, and the size and shape of the reflecting member 42 provided at the tip can be freely designed. It is possible. What is important is that the angles of inclination of the plurality of reflecting surfaces 45 provided on the upper surface of the reflecting member 42 are made different from each other so that light incident from various angles is taken into consideration, The most suitable one reflective surface 45
And adjust (rotate the rod 41 by an appropriate angle) to reflect the incident light incident on the reflecting surface 45,
All that is necessary is for the reflected light to enter the trainee's eyes.

In the above embodiment, the reflecting surface 45 is provided radially with the rod 41 as the center, but this need not necessarily be radial, and if it is the upper surface of the reflecting member 42, a plurality of reflecting surfaces 45 are provided. May be provided in any manner.
For example, a plurality of circular reflecting surfaces may be randomly formed on the upper surface of the reflecting member. In the above embodiment, the reflecting surface 45 has different angles a of the reflecting surface 45 with respect to the rod 41, but the angle of the reflecting surface 45 is not the angle with respect to the rod 41, but is generally In addition, the inclination angle of the reflecting surface 45, that is, the angle with respect to the horizontal plane may be different from each other. Further, the different angles can be set arbitrarily. The size, shape, and number of the reflecting surface 45 can be freely designed, but if the size is made too small, it becomes difficult to confirm the reflected light, so that the reflected light can be easily confirmed. It is preferable to set to. The non-reflective surface 46 can be implemented without any particular provision.

Further, the reflecting member 42 may be detachably mounted instead of being fixedly provided on the rod 41. For example, the outer shape is a substantially cylindrical shape, a large through hole that allows the club shaft to penetrate therethrough is provided in the center thereof, and a notch having a constant width is provided in the outer peripheral direction from the through hole, and both ends of the notch are The reflection member 42 can be embodied as a detachable type by extending outwardly so that the extending portions can be tightened with bolts and nuts. This extension and bolt
Although the nut and the through hole serve as a mounting portion to the club shaft, in this embodiment, the mounting portion and the reflecting member are integrated. A plurality of reflecting surfaces are provided on the upper surface of the reflecting member, and the inclination angles of the reflecting surfaces are different from each other, as in the above embodiment. By making it detachable in this way, this reflecting member can be attached not only to a rod-shaped swing practice stick as a golf swing practice tool by itself, but also to various actual golf clubs. It can also be used.
