Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a golf practice tool suitable for practicing golf swings.

[Conventional technology]

Conventionally, this type of golf practice equipment has been commercially available in various forms, from so-called open-air driving ranges to those for practicing in the garden at home, and even those for practicing indoors. . In addition, these practice tools are generally designed for practicing by hitting an actual golf ball, a pseudo ball fixed to a rotating tee, a pseudo ball with a grapple connected to a pin, etc. with a club.

[Problem to be solved by the invention]

However, conventional golf practice equipment as mentioned above
None of these methods are designed to help students learn or feel the correct swing form based on thorough golf swing theory, and are only used for repeated practice of shots and swings. Therefore, regardless of when an excellent coach or the like accompanies and instructs, when amateurs practice alone, they repeat unreasonable or incorrect forms on their own and acquire them as bad habits, resulting in a decrease in distance. Not only does it not develop, but due to the peculiarities of the form, the balls hit become sliced balls or hook balls, and the trajectory is not stable, etc., making it difficult to improve, or even if you make a little progress, you can't improve quickly. There were problems such as it stopping.

This invention was made in view of the above-mentioned circumstances, and its purpose is to apply a certain theory regarding the swing mechanism that the present inventor has derived and established based on observation and analytical research of the swing forms of first-rate professional golfers, etc. To provide a golf practice tool suitable for swing practice based on the theory of "pendulum separation motion" and effective for improving golf skills regardless of age or sex.

[Means to solve the problem]

In order to achieve the above object, the golf practice tool of the present invention has a base plate that is installed on the floor and is used as a foothold by a golf practitioner, and a base plate that is placed on the front side of the practitioner who takes a swing posture and is connected to the base plate. A grip carriage assembly comprising a swing trajectory guide member provided at a fixed position and a grip member, and guided along the trajectory of the swing trajectory guide member when a practitioner grips the grip member and performs a swing movement. , this grip carriage assembly is provided so that the practitioner's swing is hand-first B! A braking means is provided to brake the slide member if it is not in the position, and a braking means is provided near the measuring part of the knee in the practitioner's swing form, so that the movement reaches the top position at the moment the practitioner's knee makes contact during the take-back movement. A top position indicating member that allows the practitioner to sense this by contact with the top position indicating member, and a top position indicating member that is provided near the measuring part of the knee in the practitioner's swing form, and is provided to indicate that the movement has reached the impact position at the moment the knee makes contact during the forward swing movement. and an impact position support member that allows the practitioner to feel the impact position by contact with the impact position support member.

[Effect]

The golf practice tool of the present invention having the above-mentioned structure is a swing that implements the theory of "pendulum separation motion" regarding the swing mechanism, which the present inventor derived based on observation and analytical research of the swing forms of first-rate professional golfers, etc. The idea is to improve your golf skills by using it for practice, and I will first briefly explain this theory.

Incidentally, professional golfers and top amateurs unconsciously perform this "pendulum release motion" when swinging.

In the following explanation, many golf players are right-handed, so the explanation will be made with right-handed players in mind, but if you are left-handed, you can read "right" and "left" in the following explanations interchangeably. .

A series of movements in a golf swing, from address movement to take-back movement, top, down (forward) swing movement, impact, and follow-through, can usually be compared to a pendulum movement.

Of course, it is not possible to obtain a sufficient head speed on the side sole simply by rotating the head by its own weight, so force is applied to increase the speed of the head through movements of the hands, shoulders, hips, etc. At that time, for example, emphasis is placed on ``hitting with the right hand'' from the top toward impact, but this requires unnecessary force and is not effective, as illustrated and explained below.

Prepare a piece of string and tie a weight, such as a 5-yen coin, to one end of it. Hold the other end of the string with your left hand and let the weight hang, then grab the weight with your right hand and move it to the right until the string becomes taut.
As shown in Figure 5(a), throw the weight as hard as you can to the left (swing direction) with your right hand so as to increase the speed of the pendulum. This corresponds to the action of hitting with the right hand during the downswing; the more force is applied, the more the string becomes slack, and as can be seen from the fact that it does not result in a pendulum motion, it is clear that the power of the right hand is being wasted. It is. On the other hand, as shown in Figures 5(C) and (C), if you grab the weight with your right hand and tension the string, then pull the string with your left hand, and the weight will come to the front of your left shoulder (i.e., the impact zone). At the same time, the base of the left hand used for this pulling motion is the left shoulder, which is the base, and the weight is pulled upwards and backwards so that the string does not become slack (the weight will be accelerated until it reaches the impact zone, and from there the left shoulder will be pulled up). The string shifts to a lateral motion due to the string being pulled taut and rotates, further increasing its speed (
5th picture wheel).

This pendulum separation movement is, in principle, the same in a golf swing using an actual club; during the downswing, the pendulum movement is faster and smoother by pulling with the left hand rather than hitting with the right hand, and by pulling the left shoulder up. The shaft (corresponding to a string) becomes like a whip, and the head (
(equivalent to a weight) is accelerated. In other words, in the pendulum release motion, the initial velocity is applied from the top to the head (weight) by the pulling action during the downswing, and the speed continues to increase until it reaches the impact zone, and even after impact, the lateral movement of the shaft due to the pulling allows the head to move smoothly and effortlessly. can be accelerated. For example, when driving a nail with a hammer, rather than applying force to the handle and hitting the nail with the head of the hammer, you pull the handle downward and use the weight of the head of the hammer to control the falling speed. This is supported by the fact that accelerating by pulling allows you to drive the nail straighter, deeper, and more easily. This is because humans need much less power to pull something than to hit it.

However, in the actual swing using a club,
It is not possible to obtain enough head speed to hit the ball far by simply pulling the end of the string with your left hand, as shown in Figure 5, by simply pulling the end of the string with your left hand. This is compared to the weights in the experiment above.

This is because the do is several steps heavier and the shaft is much more rigid than the string. Furthermore, it goes without saying that pendulum motion and lateral motion are not mutually independent motions, but must be smoothly integrated into a series of motions. Therefore, when swinging with a club using a pendulum separation motion,
After the impact, during the take-pack movement from address to the top, so that the pendulum movement from the top and the lateral movement from the impact zone can be smoothly performed, and sufficient head speed can be obtained to swing the ball powerfully. Create a twist for lateral movement.This twist accelerates the lifting motion of the left shoulder in the string and weight experiment described above.

To explain this diagrammatically, first, from the address position A shown in FIG. 6(a), relax the left arm 62 holding the club 61 and the right arm attached to it, and rotate it approximately 45° to 60° to the right using the left shoulder 6θ as the base point. let At this time, only move your arms; do not move your shoulders, hips, or lower body. This angle is effective in ensuring a consistent hand-first or left-hand pull action in the forward swing from the top, and also provides a comfortable and smooth transition into lateral movement in the follow-through following the impact zone. ,
Make the shaft flex (works).

Next, following this take-back for the whip movement (arrow ■ in Figure 6 (c)), move the left shoulder 60 as shown by arrow ■ without changing the relationship between the shoulder and hand obtained in the take-back in step (■). Rotate to the right until it stops naturally.At this time, keep the left side of your body, such as the left abdomen 63, soft and allow it to follow the movement of your left shoulder 60.With this take-back and bending motion, you can find the position where it stops naturally without twisting forcibly. It is the top, and from this position the 6th
As shown in Figure 0, rotate the left shoulder 60 counterclockwise and while applying pressure from the right belly 64, pull the club B1 down to the impact zone of the sixth wheel.

In this impact zone, the left shoulder 60 in Figure 6 (c)
A torsion angle is formed between the fly ball line F parallel to both shoulders and the line W connecting both knees due to the right rotation of the ball and the subsequent rotation of the hips during the downswing at φ (Fig. 6). If the left shoulder 6o catches the ball and continues to apply pressure from the right abdomen 64 without applying the pull or hand first action created by the angle created by the take-back for lateral movement in Figure 6(a) above, the left shoulder 6o will move to the above torsion angle. Because of this, the ball is pushed upward and backward at once, and the club returns upward and backward without making a 61 movement. This is a follow-through movement due to lateral movement (No. 6
Arrow ■ in figure (f)).

In this pendulum separation movement swing, it is best to stop the top at a position where the take-back movement naturally receives resistance depending on the stiffness of each person's body (there is no need to take a large swing, so the face remains in the address state) It is easier to impact the ball accurately, and since it uses the twist between the hips and shoulders mainly for the pulling motion, it is easier for people with stiff bodies or weaker strength than swings that use unnecessary force such as hitting with the right hand. He can accurately hit the ball long distances.

In the golf practice tool of the present invention, the practitioner sets a swing stance on the base plate, holds the grip member of the grip carriage assembly, and practices the swing by the pendulum separation movement as described above with the guidance of the trajectory guide member. If the practitioner's swing is not a hand-first swing based on the pull of the left hand, the movement of the grip carriage assembly will be braked by its braking member, allowing the practitioner to smoothly move the slide member along the trajectory guide member. You can practice while correcting your swing.

Further, the top position indicating member is located at the knee part of the left leg of the practitioner, for example, when the practitioner performs a take-back motion as shown in FIG. 6(C).
When the ball 5 slowly moves inward, it comes into contact with the inside of the ball at the top position of the swing, allowing the practitioner to sense that the movement has reached the top position. Therefore, by repeatedly practicing the take-back motion, the practitioner can repeatedly check at which top position the left knee contacts the top position indicating member, and thereby determine the optimal top position and downswing transition. The user can sense the timing, and can always swing based on the optimal top position and timing even in the actual swing.

The impact position indicating member is used when, for example, the knee part 66 of the right leg of the practitioner moves inward as the right abdomen 64 is pressed during the downswing movement (FIG. 6(C)) following the top position. By making contact with the inside of the impact zone as shown in Figure 6, the practitioner can sense that the movement has reached the impact zone. As a result, the moment the practitioner senses that the swing has reached the impact zone during a downswing movement from his or her optimal top position established as described above, the practitioner pulls his left shoulder backwards and upwards and performs a follow-through movement using lateral movement. By repeatedly practicing the transition, you will be able to get a feel for the timing and form of the follow-through movement, and you will be able to stably reproduce the timing and form that you have learned in this way in your actual swing.

In addition, the take-back movement of the swing due to the above-mentioned pendulum separation movement (■, ■ in Fig. 6 (c)), the downswing movement (■ in Fig. 6 (c)), and the follow-through movement (Fig. 6 ( ■) in f) is not an independent operation, but needs to be performed smoothly as a series of operations. In particular, it is desirable for the top player to not be in a stationary state, but to use the reaction from the takeback to apply a pull with his left hand and transition to the downswing, but the golf practice tool of this invention allows for such linked movements. It can also be used effectively to master timing.

〔Example〕

Hereinafter, the first embodiment of the golf practice tool of the present invention will be described.
This will be explained with reference to FIGS. 4 to 4.

Reference numeral 1 in the figure is a base plate on which the golf practitioner T (Fig. 3) stands on as a foothold for swinging, and a support mount 2 is fixed to the front center of this base plate 1. . The pillar mount 2 has two pillars parallel to each other, that is, a top pole 3.
and the lower end of the impact pole 4 is attached. Top pole 3 and impact pole 4 are at the rear (practice T
(side). This angle of inclination may be adjustable. Near the upper ends of the top pole 3 and the impact pole 4, a common fixture 9 having a tightening screw 8 is used to attach a top position knee pad 6 as a top position indicating member and an impact position knee pad 7 as an impact position indicating member, respectively. is installed in a height-adjustable manner.

The lower ends of these poles 3 and 4 each have a knee pad 6.
7 are connected with spring joints 10 and 11 to provide cushioning properties.

On the other hand, on the front side of the column mounting base 2, two guide member columns 5 = -52 are arranged parallel to each other and the two poles 3 and 4 are arranged parallel to each other.
The gap between the two is slanted forward and fixed at the lower end. The inclination angles of these supports 51, 5□ can also be made adjustable. Reference numeral 15 indicates two pillars 58,
This is a reinforcing rib stretched between the middle parts of 5□. Fixtures 12.13 are installed near the upper ends of these columns 50, 5□.
The track guide member 14 is mounted so that its height can be adjusted.

The trajectory guide member 14 has an arc shape that substantially approximates the trajectory of movement near the grip during a swing, and is fixed to the pillars 51 and 52 so that both ends thereof face diagonally rearward and upward.

As shown in FIGS. 4 (Q and (C)), the track guide member 14 is formed with a guide groove 16 that is open on the inner edge side over its entire length. As shown by reference numeral 17, the cross section is narrower than the center part over a predetermined width.The width of the guide groove 16 does not need to be the same over the entire length; The width may be gradually increased from the center toward both ends.

The grip carriage assembly 18 guided by the track guide member 14 includes a slide member 19 that is slidable along the guide groove 16, and a pin 2 attached to the slide member 1g.
Lever member 21 and lever member 2 pivotally connected by 0
1 (inside the track guide member 14).

The slide member 19 has its inner edge and outer edge formed in the guide groove 1.
Although it is formed to have almost the same curvature as the guide groove 16, the overall width is slightly smaller than that of the guide groove 16. A through hole 24 is formed which is tapered inwardly and outwardly from approximately the center. The lever member 21 is pivotally attached to the slide member 19 by a pin 20 while being inserted into the through hole 24, and the lever member 21 is pivotally attached to the slide member 19 by a pin 20.
Month 8 is Lever 2! Starting guidance is performed by fitting the slide member 19 into the guide groove 16 from one end so that the part slightly inside the pin 20 (on the practitioner T side) is located in the aperture opening 17 of the guide groove 16. It is attached to member 14.

The length from the pin 20 of the lever member 21 to the free end (outer end) E (that is, the turning radius of the lever member 21) is slightly longer than the distance from the pin 20 to the outer circumferential wall of the guide groove 16. When T holds the grip member 22 and swings in the direction of the arrow in FIG. 4, the swing is not a pull-based swing, that is, a no-hold-first swing, but is a swing in which the grip is pushed with the right hand. As shown by the dashed line in FIG. 4, the free end E of the lever member 21 comes into contact with the outer circumferential wall of the guide groove 1B, so that the swing is braked. That is, the lever member 21 also has the function of a braking member that brakes the slide member 19 when the swing is not in the hands-first state. Further, as shown in FIG. 7, the slide member 19 is tapered from the center where the lever member 21 is attached to both ends, and is long as a whole. If both sides are wider than the corresponding center part, the grip carriage assembly 18 can be moved smoothly, and the slide member 19 is difficult to separate from both ends of the guide groove 16.

In addition, in the illustrated embodiment, in order to strengthen the lower body of the practitioner T, four spring-equipped belts (tensile elastic means') 25t each have their lower ends secured to the four corners of the base plate 1.
, 25□, 253, and 254 are provided, and by locking the upper ends of these belts to the waist belt B of the practitioner T, a downward load can be applied to the lower body of the practitioner T. There is.

To explain an example of how the golf practice equipment of this embodiment is used, the practitioner T first uses the knee pad 6 for indicating the top position,
Impact position indicating knee pad 7 and trajectory guide member 14
Adjust and set the position of the four spring belts 2 as appropriate.
51, 25□, and 253-254 on the waist hold B, and take a stance for swinging on the base plate 1. Then, the user holds the grip member 22 and performs a take-back operation from the address using the pendulum separation movement described in FIGS. 6(a) and 6(c). At this time, the moment the inside of the left knee 85 comes into contact with the top position indicating knee pad, Doro, the user is made to realize that position as his own top position.

Also, the forward swing from the top position (Figure 6 (
In steps 6) to (f)), practice so that the slide member 19 of the grip carriage assembly 1B can slide smoothly along the guide groove 16 of the track guide member 14, focusing on pulling with the left hand. , the moment when the inside of the right knee 66 comes into contact with the impact position indicating pad 7 is to be understood as the impact position or impact zone (Fig. 6 (f)) where the whip motion is followed through by lifting the left shoulder. . Of course, take-up at the top.

The transition from the swing to the downswing and the transition to the follow-through movement in the impact zone should be practiced so that the entire swing is performed smoothly as a rhythmic series of movements.

Although the grip carriage assembly of the above embodiment uses a slide member that slides within the guide groove, an embodiment in which a ball bearing, a roller bearing, etc. is appropriately incorporated into the slide member or the guide groove is also possible. In addition, the pad for indicating the top position and the pad for indicating the impact position are equipped with a sounding body such as a small speaker or a sounding device that detects the contact with the knee.
A sensor such as a touch sensor or a pressure-sensitive element may be provided to activate a drive circuit of an indicator such as a photodiode, and a sound or light signal may be generated at the top position and the impact position.

〔Effect of the invention〕

As described above in detail, the golf practice tool of the present invention includes a swing trajectory guide member, a grip carriage assembly guided by the swing trajectory guide member, a braking means for braking the swing when the swing trajectory guide member is not in the swing hand first state, and a top. With the provision of a position indicating member and an impact position indicating member, it is possible to sense and master the correct form based on the principle of pendulum separation movement at an appropriate timing with a sense of rhythm, ensuring golf skills regardless of age or gender. This can greatly contribute to increasing the interest of amateur golfers and others in playing golf.
