Description

  The present invention relates to an auxiliary tool for practicing golf swing, and more particularly to a golf swing practicing tool that allows a golf swing practitioner to perform repeated swing exercises in an ideal form.

Conventionally, many golf swing practice tools and swing foam correction tools are known.
For example, in Japanese Patent Application Laid-Open No. 54-6178 (Patent Document 1), the trunk of a practitioner performing a swing and one arm (for example, the right arm) are forcibly brought close to each other with a belt or the like and the swing is kept in that state. Correction tools have been proposed. According to this swing foam corrector, one side can be forcibly kept closed, but the corrector does not act on the other arm, and the so-called triangle between both shoulders and both arms is used. It is difficult to maintain.

  Japanese Utility Model Laid-Open No. 4-70066 (Patent Document 2) proposes a tool for correcting the movement of both arms, and according to the invention, both arms are always brought close to the torso of the practitioner by a belt or the like. The practitioner can forcibly keep the sides closed and practice swing. However, when both sides are forcibly maintained in this way, for example, during backswing, the right arm (in the case of a right-handed person) is kept closed and the distance between both arms is constant. Although it is desirable in that it is kept at an interval, since the left arm is also maintained in a closed state, the left arm cannot be swung naturally, resulting in a cramped and unnatural swing.

In JP-A-8-336628 (Patent Document 3), as a golf practice tool that allows a swing practice by always tightening the right side, a pad part having a predetermined thickness and facing the side, A golf practice tool comprising a side pad that is extended from both ends of the pad portion and includes a fastening band for detachably fastening to the upper portion of the arm or the shoulder is disclosed. This golf practice tool seems to be able to learn the swing form with the right arm on the right side by putting the right arm on the pad when swinging, but there is no restriction on the forearm of both arms Therefore, it is not suitable for practice to maintain a triangle consisting of both shoulders and arms.
Patent Document 3 also discloses a golf practice tool that combines a wrist supporter made of an elastic band that restrains both wrists. However, although such a wrist supporter can prevent the wrist from opening, it cannot prevent the wrist from being turned (turned) at the time of impact, and cannot perform a square impact practice in golf swing.

  Utility Model Registration No. 3051619 (Patent Document 4) is provided with a belt-shaped expansion / contraction section that expands and contracts on the bangles for the purpose of handcuffing the bangles mounted on both arms. An adhesive part that can be easily peeled and peeled off is provided in the upper center part, so that the inner adhesive part surfaces of both bracelets can be connected together during gripping operation, and some expansion and contraction movements such as after waggle and impact Is a bracelet that can prevent injury by relaxing the expansion and contraction, extending the expansion / contraction part for adjusting the expansion / contraction range for unbalanced or unreasonable movement during exercise and peeling the adhesive surfaces together Is disclosed. As with the golf practice tool described above, such a bracelet still has a problem that it cannot suppress wrist turn in the impact zone.

Japanese Patent Laid-Open No. 54-6178 Japanese Utility Model Publication No. 4-70066 JP-A-8-336628 Utility Model Registration No. 3051619

  The above-described conventional swing training tool is generally intended to correct the preferred swing by restricting the opening of both elbows by fixing both arms or both wrists with a belt or the like. When the swing was removed, it was easy to return to the swing with the original elbows open, and the swing correction effect was poor.

  In addition, with the evolution of golf clubs in recent years, ideal golf swings have also changed. In other words, the old driver consisted of a persimmon head and a heavy steel shaft, and the swing at that time emphasized the movement of turning the hand (arm) back with a square grip to increase the head speed. In contrast, recent clubs, especially drivers, have become large-capacity titanium heads and lightweight carbon shafts, and have evolved into clubs with high moments of inertia. If you turn your hand too much like the old swing in the latest club, the direction of the ball will deteriorate due to the high moment of inertia, so the recent swing has a strong grip and the hand rotates in the impact zone. Swing with an emphasis on body rotation is the mainstream so that the club face can have a square impact.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a practice aid that has a high swing practice effect by reducing the gap between when a swing practice tool is worn and when it is not worn as much as possible.
In addition, the present invention suppresses hand rotation in the impact zone, and can easily perform repetitive practice of on-plane swing (swing with the club head on the correct swing plane), which is the current ideal golf swing. It is an object of the present invention to provide a practice aid.

The golf swing practice assisting tool of the present invention includes an interval holding body closely interposing between both wrists or both forearms in a triangle formed by both shoulders and grips during golf swing, and the holding body provided with the holding body. And a band that can be attached to one wrist or forearm.
The golf swing practice assisting tool of the present invention includes an interval holding body closely interposing between both wrists or both forearms in a triangle formed by both shoulders and grips during golf swing, and the holding body provided with the holding body. And a rope for hanging from the neck.

It is preferable that the spacing member is formed with a recess along the curved surface of both wrists or both forearms at the contact portion between both wrists or both forearms.
It is preferable that the spacing member is made of any one of foamed polystyrene, foamed urethane, synthetic resin, synthetic rubber, or a combination thereof.

The golf swing practice assisting device of the present invention strives for swing practice so that the practitioner does not widen the distance between his arms when swinging using this assisting device. There are few sensory differences between the two and you can definitely learn the ideal swing form.
Further, the golf swing practice aid of the present invention has the effect of suppressing hand rotation in the impact zone. That is, when the golf swing is rotated so that the hand is turned back, the distance between both wrists or both forearms becomes narrower. However, according to the golf swing practice aid of the present invention, the distance at the time of addressing Is kept during swinging, and the rotational movement to return the hand is inevitably suppressed.
The assisting tool for practicing golf swing according to the present invention is lightweight and compact, excellent in portability, can be practiced easily and frequently without any restrictions on practice place and practice time.

Next, the golf swing practice aid of the present invention will be described with reference to FIGS.
FIG. 1 is a front perspective view of a golf swing practice assisting tool 1 (hereinafter sometimes simply referred to as assisting tool 1). The assisting tool 1 is a triangle formed by both shoulders and grips during golf swing. An interval holding body 10 closely interposing between both wrists or both forearms, and a band 20 provided in the interval holding body 10 so that the interval holding body 10 can be attached to one wrist or forearm. .

  As for the size and shape of the spacing member 10, there are no special restrictions as long as it can fit within the triangle formed by both shoulders and grips during golf swing and can be in close contact between both wrists or both forearms. Absent. In the embodiment shown in FIG. 1, a flat plate block having a length, width, and thickness of about 10 cm × 15 cm × 5 cm is used. Recesses 12L and 12R having substantially semicircular shapes are formed at both left and right ends of the spacing member 10, and both wrists or both forearms are fitted into the recesses 12L and 12R. The interval holding body 10 is sandwiched between the wrists and the forearms of the practitioner, so that the interval between the wrists and the forearms is restricted during the swing. In addition, wrist swing in the impact zone is suppressed during swing practice.

  Therefore, it is necessary that the spacing body 10 has a hardness and elasticity that do not deform against the pressing force by both wrists or both forearms during addressing and during swinging. The weight of the spacing member 10 is not particularly limited as long as it does not interfere with the swing practice, but is preferably as light as possible.

  Considering suitable conditions such as the above size, shape, etc., the spacing member 10 should be formed of any material such as polystyrene foam, urethane foam, synthetic resin, synthetic rubber, or a combination thereof. Is preferred.

In the auxiliary tool 1 of the present invention, there is no special reason for distinguishing between the case where the spacing member 10 is closely attached to both wrists and the case where the spacing member 10 is closely attached to both forearms.
Further, there is no special reason for distinguishing between the case where the spacing body 10 is attached to the right wrist or right forearm portion and the case where it is attached to the left wrist or left forearm portion, and it may be selected according to the preference of the practitioner. However, from the experience and sensitivity of the inventors, it is preferable to attach to the left arm (in the case of a right-handed person) for approach practice.
Note that the case in which the spacing body 10 is attached to both forearms or both wrists by the band 20 or other means is not preferable because it restricts both forearms or both wrists, and is excluded from the present invention. .

The band 20 is a stretchable elastic band, and is directly fixed to the interval holding body 10 so as to cover any one of the recesses 12L and 12R. By attaching a hook-and-loop fastener to the back surface of one end of the band 20 and engaging with the hook-and-loop fastener 14 on the side of the distance holding body 10 which is paired with the hook and loop, the auxiliary tool 1 can be easily attached to and removed from the forearm or wrist. It is preferable to do so.
The right or left wrist or forearm portion is fitted into any of the recesses 12L and 12R, and the wrist or forearm portion is tightened by the band 20, so that the assisting tool 1 is attached to one wrist or forearm portion of the practitioner. Will be attached.

  The substantially semicircular recesses 12L and 12R are formed by curved surfaces that fit both wrists or both forearms, and the degree of incision (depth) of the recesses 12L and 12R is determined by the hardness of the spacing holder 10. It is determined in consideration of elasticity.

  Then, the usage method of the auxiliary tool 1 of this invention is demonstrated, referring FIG. FIG. 2 (1) is a front view showing the address of the practitioner wearing the assisting device 1, and FIG. 2 (2) is a side view showing the backswing state as seen from the rear of the flying ball line.

  The practitioner first attaches the assisting tool 1 to the right or left wrist or forearm portion with the band 20. Whether the space holding body 10 is close to the grip or between the forearm is close to the grip or close to the elbow depends on the practitioner's preference, but creates a square grip on the swing plane It is important. To do this, grip both hands so that the line connecting the elbows is parallel to the shoulder, waist, and stance. The flat block-shaped spacing holder 10 can easily check the parallel state.

  The practitioner takes back the club and starts backswing while holding the inverted triangle formed by the arms and shoulders formed in the address state shown in FIG. At this time, the swing exercise is performed while paying attention not to leave the wrist or forearm on the side not fixed by the band 20 from the indented recess 12L (or 12R). On the other hand, as long as the auxiliary tool 1 is worn, it is possible to easily detect when the free wrist or forearm portion is away from the recessed portion 12L (or 12R) in close contact.

  Following the takeback and backswing, the practitioner can check the closeness during the swinging operation from the top swing, down swing, impact, follow-through to the finish. It is sufficient to pay particular attention to the impact zone while moving between the mouths.

  It should be noted that points to be noted for executing on-plane swing in each operation stage of golf swing are as follows. That is, in the takeback, the club head should be placed on the swing plane by cocking the wrist, and the distance between the inverted triangle at the time of addressing and the body and grip should be maintained. In the backswing, swing the club to the right shoulder side while twisting the trunk, which is the center of the body. As a result, due to the moment of inertia of the club, in the top swing, the club fits in a point substantially parallel to the ground. The ideal top swing has a left arm, shaft, and face on a single plate. In the initial stage of downswing, the weight of the arm and the club is used to let the club fall naturally and place the club on the swing plane. Next, the club head is accelerated along the trajectory of the impact zone without unraveling the wrist cocking as much as possible. By releasing the cocking of the wrist immediately before the impact and releasing the club head (also referred to as a release operation), in the follow-through, the maximum centrifugal force acts on the club head, and then the finish is reached.

  The distance holding body 10 has an effect of restricting the left and right wrists or forearms from contracting and approaching the distance holding body 10 in combination with the action of freeing one of the left and right wrists or forearms. Have. Therefore, while maintaining the inverted triangle at the time of the address, excessive hand rotation (roll) in the impact zone is also suppressed.

Next, another embodiment of the present invention will be described with reference to a perspective view of the golf swing practice aid 2 shown in FIG.
The assisting tool 2 includes a distance holding body 10 that is in close contact between both wrists or both forearms in a triangle formed by both shoulders and grips during golf swing, and the distance holding body 10 attached to the distance holding body 10 from the neck. It is comprised from the rope 22 for hanging. Here, the interval holder 10 is the same as the interval holder 10 of the auxiliary tool 1 described above.

The rope 22 is suspended from the neck to prevent the distance holder 10 from falling, and the distance between the trainer's neck and the grip is evenly spaced during the series of swings from address, bag swing and follow-through. This is effective for practice that does not break the triangle.
For this reason, it is preferable that the rope 22 has a length at which the distance between the neck and the grip is appropriate, and the length can be adjusted, or has a stretchability.

In order to practice using the auxiliary tool 2, first, the distance holder 10 is suspended from the neck, addressed in a state in which the rope 22 is stretched (stretched), and the auxiliary tool 1 is maintained while maintaining the tension. Perform a series of swings as described in How to use. When the auxiliary tool 2 is used, the advantage of using the auxiliary tool 1 is enjoyed, and the distance between the neck and the grip, which is the center point of the swing, can be kept constant by the action of the rope 22. it can. Therefore, particularly in takeback, it is effective for practice of maintaining the square face surface while putting the club head on the swing plane.

It is a front perspective view of the auxiliary tool for golf swing practice showing one embodiment of the present invention. It is the front view (FIG. 2 (1)) which shows the state of the address of the practitioner who equipped the auxiliary tool same as the above, and the side view (FIG. 2 (2)) seen from the back of the flying ball line which shows the state of backswing. It is a perspective view of the auxiliary tool for golf swing practice which shows other embodiment of this invention.
