Description

Golf swing straightener

The present invention relates to a golf swing correction tool that is used during golf club swing practice and corrects the swing trajectory thereof.

Generally, golfers practice for the purpose of stably hitting the ball with an ideal trajectory.

In order to hit the ball with an ideal trajectory, the golf club's swing trajectory for hitting this ball must be the correct swing according to the club used and the type of shot (eg, approach shot, bunker shot, or lob shot). It needs to be along the plane.

By the way, especially for beginners and intermediate players, it is extremely difficult to confirm the deviation between their swing trajectory and the ideal swing plane.

Conventionally, for example, a technique as disclosed in Patent Document 1 has been proposed to deal with such problems.

In this technique, a guide plate made of a flat plate inclined according to the lie angle of a golf club to be used is installed in front of the player's foot position so that the club shaft moves in parallel along the guide plate. The present invention relates to a correction tool that allows an ideal swing plane to be obtained by performing a swing.

JP 2007-61478 A

Incidentally, in the above-described conventional technology, the following problems to be improved still remain.

That is, the length of the guide plate in the swing direction is set to be substantially equal to the player's stance width, and when the swing path of the player deviates from an ideal swing plane, the club shaft during the swing is There is a risk of collision or contact with the guide plate.

The swing corrector is used to confirm that the swing trajectory is on the ideal swing plane, but rather to correct the swing trajectory that is offset from the ideal swing plane. Often used.

Therefore, this type of corrector must be premised on the collision or contact between the aforementioned guide plate and the club shaft. Such collision or contact may damage the golf club or the guide plate. Moreover, since it may cause an impact force to the player, it is necessary to take measures against it.

The present invention has been made in view of such a conventional problem, and in a swing corrector configured to guide movement of a club shaft by a surface during a swing of a golf club, It is an object of the present invention to provide a swing corrector that can mitigate the impact and suppress these damages even when the swing corrector collides with or comes into contact with the swing corrector so that the player can practice with peace of mind.

In order to solve the above-described problems, a golf swing correction tool of the present invention is a swing correction tool that is used when practicing a golf club swing and corrects the swing trajectory of the golf club. A main body formed of a flexible material installed on the main body, and an upper portion of the main body is provided with guidelines for an ideal swing direction and a guide for the player's foot position. A swing guide surface that is parallel to the guideline and inclined according to the lie angle of the golf club is provided at a portion opposite to the side where the golf ball is located.

The golf swing correcting tool of the present invention is used by being installed in front of the player's feet. The golf club is gripped so that both feet follow the guidelines provided on the upper portion of the main body. The leg position, that is, the stance is determined so that the club shaft is parallel to the swing guide surface of the main body, and the address is determined.

While the player maintains a determined address, the player swings using the guidelines provided at the top of the main body as a guideline. If the swing trajectory is on an ideal swing plane, The club shaft moves along the swing guide surface of the main body, and the golf club is shaken out without resistance.

Here, even when the player gets up during the swing, the axis of the swing is shifted upward, and the swing plane is shifted in the vertical direction, the contact between the club shaft and the main body does not occur, and the corfu club has no resistance. May be shaken out.

In such a swing, the player may misunderstand that he has made an ideal swing. In order to prevent this, it is preferable that the golf ball be placed in the impact zone of the golf ball at the determined address. And whether or not the golf ball is an ideal swing is recognized depending on whether or not the golf ball has been launched.

On the other hand, when the swing takes back, the trajectory is inward from the ideal swing plane, and when down swing, the trajectory comes from the inner side of the ideal swing plane, that is, the guideline. The golf club head or shaft collides with or comes into contact with the main body.
This allows the player to recognize that the swing is out of the ideal swing plane.

In addition, the golf club head or shaft collides with the main body during a downswing even when the downswing is a trajectory that enters the impact zone from the outside of an ideal swing plane, that is, a trajectory that intersects the guideline. Alternatively, the player can be informed that the player is making a swing that deviates from the ideal swing.

As described above, when the golf club hits or comes into contact with the main body by performing a swing off the ideal swing plane, the main body is made of a flexible material. Thus, the impact force at the time of the collision or contact is alleviated to prevent the main body and the golf club from being damaged, and the impact force applied to the player can also be alleviated.

And the said main body can be formed in a hollow shape with a flexible material.
With such a configuration, the impact force at the time of the collision or contact of the golf club described above can be absorbed by the deformation of the flexible material and the contraction of the internal gas, and the impact force absorbing effect can be enhanced. it can.

Also, after the main body is deformed, its shape is quickly returned to its original shape by the pressure of the internal gas.

In the golf swing correction tool of the present invention, the main body is provided with a vent for air intake / exhaust of gas into the main body, and the vent is provided with an opening / closing member for opening / closing the vent. It can be.

With such a configuration, during use, the main body is filled with gas from the vent to form a swing corrector, and after use, the gas in the main body is exhausted from the vent. However, the volume of the main body can be reduced by utilizing its flexibility, and handling and carrying after use can be facilitated.

In addition, the main body is formed in a mat shape, and a linear bent portion is provided in the surface, and two swing guide surfaces are formed by bending in a mountain fold at the bent portion. It can also be.

By adopting such a configuration, the internal volume of the main body is reduced, the amount of air supply required during expansion to be used is reduced, and the amount of exhaust during volume reduction to be stored is reduced. , It is possible to shorten the time until the above states.

It is also possible to provide a connecting member between the lower end portions of the two swing guide surfaces so as to connect the lower end portions to each other and fix the sandwich angle between the two swing guide surfaces.

By adopting such a configuration, it is possible to prevent the angle of the swing guide surface from changing by preventing the bending angle of the main body bent into a mountain shape from being enlarged.

By adjusting the interval between the lower end portions of the swing guide surfaces, the connecting member is configured to be able to adjust the sandwiching angle, that is, the above-described fold angle, so that the swing guide surface and the grounding surface can be adjusted. Can be matched with the lie angle of the golf club to be used, and an appropriate swing guide surface can be formed.

Furthermore, a pair of swing guide pieces that protrude in the vertical direction from the swing guide surface and whose protruding end portions are parallel to the swing guide surface may be provided on the swing guide surface at an interval in the guide line direction. it can.

With such a configuration, an ideal swing plane is formed by the both swing guide pieces, and when the actual swing plane is displaced, a collision or contact between the golf club and the main body is detected. Let the guide piece do it.

Since the swing guide piece is formed to be narrow, when the above-described collision or contact occurs, the swing guide piece is easily bent, so that the impact force is greatly reduced.

According to the golf swing correction tool of the present invention, the ideal swing plane is imaged by the swing guide surface formed on the main body, and the actual swing path deviates from the ideal swing plane and collides with the swing correction tool. Or the impact force at the time of contact can be relieved and damage to a golf club or a swing corrector can be prevented.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
In FIG. 1, the code | symbol 1 shows the golf swing correction tool concerning this embodiment.

The swing correction tool 1 includes a main body 2 formed in a hollow shape by a flexible material installed in front of the player (P), and an upper part of the main body 2 includes an ideal swing direction and A guideline G serving as a guide for the foot position of the player P is provided, and a portion of the main body 2 opposite to the side where the player P is located is parallel to the guideline G and the golf club (C). A swing guide surface S inclined according to the lie angle is provided.

As the flexible material, for example, a soft plastic such as polyvinyl chloride resin, polyethylene resin, polypropylene resin, polyester resin, nylon resin, or silicone resin is used.

In the present embodiment, the main body 2 is formed in a mat shape, and is bent in a mountain fold shape at a bent portion 2a provided at an intermediate portion thereof to form a pair of inclined surfaces, and The lower end portions of these inclined surfaces are connected by a connecting member 3 made of a hook-and-loop fastener, so that the included angle between the inclined surfaces is fixed.

The one inclined surface of the main body bent in a substantially triangular shape is the swing guide surface S, and the upper edge of the swing guide surface S is the guide line G.

The connecting member 3 includes a connecting piece 3a that constitutes the surface fastener described above, and a locking piece 3b that is attached to both inclined surfaces of the main body 2 and that engages and disengages each end of the connecting piece 3a. In the present embodiment, a pair of the connecting pieces 3a is provided.

In addition, the connecting member 3 prevents the spread between the end portions of the both inclined surfaces, thereby preventing the spread of these included angles, and between the lower end portions of the both inclined surfaces. The angle between the inclined surface and the installation surface is adjusted by adjusting the interval.

Thus, the angle between the swing guide surface S and the installation surface is matched with the lie angle of the golf club C to be used.

In the present embodiment, the other inclined surface of the main body 2 protrudes in the vertical direction from the other inclined surface, and a pair of swing guides whose protruding end portions are parallel to the other inclined surface. The pieces 4 are provided at intervals in the guideline G direction.

And in this embodiment, since the projecting end part of each said swing guide piece 4 is made parallel to the said inclined surface, the virtual plane formed including these projecting end parts is also said inclined surface. The virtual plane is parallel to the swing guide surface S that is the same as the swing guide surface S formed by the one inclined surface.

Further, in the present embodiment, as shown in FIG. 3, the inclined surface of the main body 2, the surface parallel to the inclined surface, and the protruding end of the swing guide piece 4 are formed thick. A certain degree of rigidity is given, and the other surface is formed thin, and a certain degree of elasticity is given.

Therefore, when the inside of the main body 2 is filled with gas and the shape is adjusted, the inclined surface, a surface parallel to the inclined surface, and the protruding end portion of the swing guide piece 4 are made flat. Further, a corner is formed at the upper edge of the inclined surface, and this corner is used as the guide line G.

Further, as shown in FIG. 2 and FIG. 3, a vent 2c for intake and exhaust of gas into and out of the inner surface of the main body 2 is formed, and the vent 2c has a vent. An opening / closing member 5 is provided to open and close the vent 2c.

The opening 2c is opened by the opening / closing member 5, and the body 2 is filled with gas to adjust the outer shape of the swing correction tool 1 according to the present embodiment, and the opening 2c is closed to form the shape. In addition, by opening the vent 2c and discharging the gas in the main body 2, the main body 2 is reduced in volume by utilizing the flexibility of the thin portion of the main body 2 and folded. enable.

As shown in FIGS. 4 and 5, the golf swing correcting tool 1 according to the present embodiment configured as described above is installed and used in front of the foot of the player P. By adjustment, the angle between the swing guide surface S and the installation surface is adjusted to the lie angle of the club used for swing practice.

Thus, when the angle of one swing guide surface S is adjusted, the other swing guide surface S (the swing outer surface S formed by the swing guide piece 4) is also adjusted in accordance with the above-described lie angle.

And as shown in FIG. 5, the said swing correction tool 1 is installed so that the guideline G may become parallel to the direction (target line T) which launches a golf ball.

As shown in FIG. 5, the player P has its legs along a guideline G provided on the upper portion of the main body, and the club shaft D of the gripped golf club C is parallel to the swing guide surface of the main body. The foot position, that is, the stance is determined so that the address is determined.

When the address of the player P is determined, a virtual plane (hereinafter referred to as a guide plane) L that imagines the direction of swinging the golf club C is formed as shown in FIG.

Thus, when the installation of the swing corrector 1 and the setup of the player P are completed, the horizontal directions of the target line T, the guideline G, and the guide plane L are parallel to each other as shown in FIG. Made.

Further, when the player P is a beginner, the swing correction tool 1 is installed so that the side on which the swing guide piece 4 is provided is opposed to the club shaft D. In addition, an address is taken, and if it is an advanced player, the swing guide surface S without the other swing guide piece 4 is installed so as to face the club shaft D.

The player P swings using the guideline G provided on the upper portion of the main body 2 as a guide. The actual swing plane R is an ideal swing plane (a plane parallel to the guide plane L). ), The club shaft D moves along the swing guide surface S of the main body 2 (the protruding end of the swing guide piece 4), and the golf club C is swung out without resistance.

Here, even when the player P rises during the swing, the axis of the actual swing plane R shifts in the vertical direction, and the swing plane R shifts in the direction approaching the horizontal plane, the club shaft D and the main body 2 No contact occurs, and the Corfu club C may be swung out without resistance.

On the other hand, when the swing takes back, the trajectory is inward from the ideal swing plane, and when down swing, the trajectory comes from the inner side of the ideal swing plane, that is, the guideline. The head or the club shaft D of the golf club C collides with or comes into contact with the main body 2.
As a result, the player P can be made aware that the player is performing a swing that deviates from the ideal swing plane.

In addition, even when the downswing is a trajectory that enters the impact zone from the outside of an ideal swing plane, that is, a trajectory that intersects the guideline G, the head of the golf club C or the club shaft D is By causing the main body 2 to collide with or come into contact with the main body 2, it is possible to make the player recognize that the swing is out of the ideal swing.

The actual swing plane R corrected by such a correction function becomes an ideal swing plane parallel to the guide plane L, and the trajectory such as the golf club C sleeping or entering from the inside before the impact is corrected. The golf club C stands and descends, down-swing is realized, and shank is suppressed.

And, as described above, when the golf club collides with or comes into contact with the main body by performing a swing off the ideal swing plane, the main body 2 is formed in a hollow shape by a flexible material. The main body 2 can be easily bent and the impact force can be reduced, so that the main body 2 and the golf club D can be prevented from being damaged, and the impact force applied to the player P can also be reduced.

Here, in the case of a beginner, the actual swing plane often deviates from the ideal swing plane, and the impact on contact with the main body 2 tends to increase due to the large deviation.

However, as described above, the swing guide piece 4 is caused to collide or come into contact with the main body 2 and the club shaft D by allowing a beginner to use the swing guide surface S on the side of the protruding swing guide piece 4. The impact described above can be reduced.

This is because the swing guide piece 4 is formed to be significantly narrower than the main body 2, and easily bends at the time of collision with or contact with the club shaft D to allow the passage of the club shaft D smoothly. by.

FIG. 6 shows a method of using the swing correction tool 1 of the present embodiment when acquiring an ideal swing plane at the time of an approach shot.

In this method of use, the swing corrector 1 is placed in such a way that the guideline G is open with respect to the target line T (in a direction obliquely opened to the left), and the player P moves the club shaft D to the swing guide piece 4. And the golf ball B is placed closer to the right foot.

Thus, an approach shot is performed by swinging along the protruding end of the swing guide piece 4.
By such a swing, the actual swing plane R becomes an ideal swing plane parallel to the guide plane G, and the so-called Zakkuri or the like that strikes in front of the ball by swinging from the inside of the ideal swing plane. , You can get a swing with less approach shank.

FIG. 7 shows a method of using the swing correction tool 1 of the present embodiment when acquiring an ideal swing plane during a lob shot or a bunker shot.

In this method of use, the swing corrector 1 is placed in such a way that the guideline G is open with respect to the target line T (in a direction obliquely opened to the left), and the player P moves the club shaft D to the swing guide piece 4. And the golf ball B is placed closer to the left foot.

Accordingly, in the bunker shot, the face of the golf club C is opened to the right from the target line T, swings along the protruding end of the swing guide piece 4, and the sand before the golf ball B In the case of a lob shot, a swing is performed so as to slide the sole of the golf club C.

Such a swing makes the actual swing plane R an ideal swing plane parallel to the guide plane G.

The golf swing correction tool 1 according to the present embodiment is configured such that, after use, the air opening 2c is opened by the opening / closing member 5 and the gas in the main body 2 is exhausted while the main body 2 is flexible. The volume can be reduced by using the property, and it can be folded as shown in FIG. 8 to facilitate handling and carrying after use.

Note that the shapes, dimensions, and the like of the constituent members shown in the above embodiment are merely examples, and various changes can be made based on design requirements and the like.

For example, as shown in FIG. 9, the main body 20 can also be formed in a triangular prism shape.
In this case, it is preferable that the side surface serving as the installation surface and the side surface portion serving as the swing guide surface S have a thickness as shown in FIG.
This is to make the swing guide surface S flat and to ensure stability during installation.

Further, as shown in FIGS. 11 and 12, the main body 30 may be formed in a quadrangular prism shape, one corner of which is cut out in the length direction, and the cut out portion may be used as the swing guide surface S. .
