Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing training device suitable for swinging a hit ball in a straight line when a golf game or practice is performed.

[0002]

2. Description of the Related Art As a device for practicing a golf ball to fly straight, a semiconductor laser is attached to a short practice pseudo club and the light is emitted from the club, as disclosed in JP-A-6-343729. A device for practicing has been proposed. This device can calculate the data obtained from the optical sensor to know the flight distance, the launch direction, the rotation of the ball, and the like, and can visually display the calculation result on the monitor screen.

Further, since a short practice pseudo club is used, it is possible to practice even in a narrow place, and the practice pseudo club provides a feeling of use that is close to the real thing by adjusting the weight. Since it uses a visible light semiconductor laser, it is safe for the eyes.

[0004]

Although it has various advantages as described above, the structure of the optical sensor portion and the pseudo club to be embedded in the rubber mat becomes complicated, and a monitor device is required. Therefore, the device is complicated and expensive. Becomes Therefore, it is difficult to easily obtain and practice. In addition, it is difficult to confirm the feeling when swinging because it is necessary to check it on the monitor screen one by one.

On the other hand, an instrument for directly performing a swing exercise by hitting a golf ball and a swing practice device for hitting a simulated golf ball have also been proposed. Although suitable for straightening foam, these instruments are not sufficient for practice in swinging the ball straight.

The technical problem of the present invention is to pay attention to such a problem, and a swing trainer for golf and a practice method for practicing the golf ball so that the player can easily and accurately perform a straight hit with a very inexpensive device. Is to realize.

[0007]

The technical problem of the present invention is solved by the following means. According to claim 1, two or three flexible columns are erected on a straight line on the left and right sides of the substrate, and a club head is drawn when the club is swung while standing in front of one of the columns. It is a swing practice device for golf characterized in that the height of each pillar is changed so that the top ends of the above-mentioned two or three pillars are located at ideal locus positions.

As described above, two or three flexible columns are erected on the right and left straight lines on the substrate, and the club head is swung by standing in front of one of the columns. Since the height of each pillar is changed so that the top ends of the above-mentioned two or three pillars are located at the position of the ideal trajectory drawn by
When an ideal or normal swing motion is performed, it can be easily discriminated that the club head hits the top ends of the two or three pillars and the hit ball would fly straight. Therefore, by practicing so that the club heads hit the top ends of the two or three pillars, the hitting ball can be improved so as to fly straight. Moreover, this swing trainer has a simple structure and can be manufactured at low cost.

According to a second aspect of the present invention, each of the pillars is integrally fixed on the support board in a state of standing vertically, and the pillars are inserted into the substrate from the bottom to the top. The swing trainer for golf according to claim 1, wherein the through hole is formed. This through hole may be a plurality of circular through holes, or may be an elongated through hole, that is, a slit.

As described above, the pillars are integrally fixed on the support board in a state of standing vertically, and the pillars are inserted into the board from the bottom to the top. Since the circular or elongated through hole is formed, each column can be erected by selecting any desired position of the through hole, or the standing position can be freely changed. Further, since the substrate is covered on the support plate at the lower end of each pillar and the support plate of the pillar is pressed by the weight of the substrate, each pillar can be stably stood.

According to a third aspect of the present invention, there is provided a substrate for standing two or three flexible columns in a straight line on the left and right, and the two or three columns are inserted into the substrate. The swing practice device for golf is characterized in that through holes for supporting are formed in a straight line on the left and right. The through hole may be a plurality of circular through holes, or may be an elongated through hole, that is, a slit.

In this way, there is a substrate for standing two or three flexible columns in a straight line on the left and right, and the two or three columns are inserted and supported on this substrate. Since two or three columns are prepared in advance, the through holes are formed in a straight line on the left and right, so that two or three columns can be inserted into the circular or elongated through holes of the substrate to stand up. You can practice your swing by itself.

According to a fourth aspect of the present invention, when two or three flexible columns are erected on the right and left straight lines on the substrate and one of the columns is standing in front of the club, the club is swung. In the golf swing practice method, the head swings so that the head touches the top ends of the two or three pillars.

In this way, when two or three flexible columns are erected on the right and left straight lines on the substrate and one of the columns is standing in front of the club to swing the club, By practicing swing so that the ball touches the top ends of the two or three pillars, the swing motion can be corrected or corrected so that the hit ball flies straight.
Therefore, it becomes a correct practice of the swing motion, and the improvement becomes faster.

As described above, when the golf swing practice device of the present invention is used, swing practice can be performed simply by preparing a substrate having a simple structure and two or three flexible columns.
A cheap swing practice device can be realized. Also, instead of using a golf ball with a struck ball, it is practice to hit the top end of the flexible pillar with the club head. The flexible pillar does not move or fall, and it stands up. You can practice efficiently and easily without the need for any troublesome special operations, because you just tremble at.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment will be described of how the swing trainer and practice method for golf according to the present invention are actually embodied. FIG. 1 is a perspective view of a swing practice device according to the present invention, in which a line 2 of an arrow indicating the normal flight direction of a hit ball is displayed in the left-right direction on a substrate 1 such as a rubber mat. At the tip of the arrow line 2 pointing to the left, a flying ball 3 flying straight is assumed.

The through holes h1 and
Opened h2 to h6 and h7. That is, a through hole h1 is formed at a position corresponding to the ball position in the middle of the arrow line 2 in the left-right direction. The lowest pillar P1 is erected in this through hole h1. Further, a plurality of through holes h2 to h6 are formed on the flying ball side of the through hole h1. These through-holes h2 to h6 are opened in the direction of the straight flight ball in accordance with the case where the hit ball accurately flies straight. Then, any one of these through holes h2 to h6 is selected to erect the highest pillar h3.

One through hole h7 is opened in the backswing direction from the above-mentioned through hole h1 at the ball position, and a pillar P2 having an intermediate height is erected in this through hole h7. A reference line 4 in a direction orthogonal to the horizontal arrow line 2 is displayed in the front-rear direction so as to pass through the through hole h1 at the ball position.

FIG. 2 is a plan view of the swing trainer shown in FIG. 1, and FIG. 3 is a vertical sectional view taken along the arrow line 2 with the flexible columns P1, P2, P3 inserted and standing upright. The lowest pillar P1 is inserted and set in the through hole h1 at the ball position of the substrate 1. A through hole h2 in the flight direction from the through hole h1
The highest pillar P3 is inserted and set to ~ h6. Then, a pillar P2 having an intermediate height is inserted and set in the through hole h7 on the backswing side of the through hole h1 at the ball position.

As shown in FIG. 3, the method of inserting and setting the columns P1 to P3 is to insert the columns of the columns P1 to P3 into the through holes h1 to h3.
7 is inserted from the lower side of the substrate 1, the column portion is penetrated to the upper side of the substrate 1, and the substrate 1 is returned to its original flat state in a projecting state, and when laid, each of the columns P1 to P3. The part 5 of the supporting board is pressed against the substrate 1. In this way, the swing is practiced in a state where the weight of the substrate 1 holds down and fixes the portions of the support plate 5 of the columns P1 to P3.

FIG. 3 shows a state in which the pillars P1 to P3 are set up on the substrate 1 in this manner. However, the highest pillar P3 is inserted and set from the through hole h1 at the ball position to the fourth through hole h5.

In this state, the golf club is practiced by swinging, and the chain line 6 is an ideal trajectory drawn by the club head when the hit ball at the time of swinging flies straight. The height of each of the pillars P1 to P3 is ideally such that the top ends of the pillars P1 to P3 are located on the trajectory 6 drawn by the club head when swinging.

Therefore, in order to make the height such that the top ends of the pillars P1 to P3 are located on the trajectory 6 drawn by the club head, the lowest pillar P1 is inserted into the through hole h1 at the ball position. The tallest pillar P3 is inserted into the through-holes h2 to h6 in the standing and flying directions, and the pillar P2 having an intermediate height is inserted into the through-hole h7 on the backswing side.

With the columns P1 to P3 set up in this way, standing in front of the through hole h1 at the ball position, the column P1
Assuming the golf ball is located at the apex of the, swing the club and practice. When viewed in the plan view of FIG. 2, when the head of the swinging club hits the top ends of the three pillars in the order of P2 → P1 → P3, the club head is on the arrow line 2 indicating the normal flight direction. Since the ball has moved, as a result, the hit ball flies straight in the same direction as the arrow line 2, which means an ideal swing.

Whether or not the club head hits the top ends of the pillars P1 to P3 can be known from the sound of the hit and the feel received from the club head. Alternatively, since the pillar hit by the club head is vibrating, each pillar P1 to
It can be easily identified by visually observing P3.

When only one or two of the three pillars P1 to P3 are hit, it means that the club head does not move on the arrow line 2 and the hit ball does not fly straight. . Therefore, the club head with three pillars P
By practicing so as to hit the tops of all 1 to P3, the hit ball will fly straight.

A plurality of through holes h2 to h6 are formed on the flying ball side of the through hole h1 at the ball position. This is because the through hole at any position is selected according to the preference of the practitioner and is the highest. This is because the pillar P3 can be set at any position. Although only one through hole h7 is formed in the backswing direction with respect to the through hole h1 at the ball position in the drawing, a plurality of through holes are formed in the backswing direction as well.
You may make it selectable and usable.

Although it has been explained that when all three pillars P1 to P3 are hit, the swing is ideal and the hit ball flies in a straight line. It can be regarded as a motion. That is, when hitting the pillar P1 on the through hole h1 at the ball position and the pillar P2 in the backswing direction, or when hitting the pillar P1 on the through hole h1 at the ball position and the pillar P3 in the flight direction. It can also be determined that the swing is ideal.

That is, even if the club head does not pass over all of the through holes h7, h1, h2 to h6 on the arrow line 2, the through hole h1 at the ball position and one through hole before and after the through hole h1. Even if it passes over, it often flies almost straight. When viewed in a plan view, the trajectory of the club head accurately describes an arc centering on the swinger, and it is extremely difficult to hit the three pillars P2, P1, and P3.

However, the two pillars P2 and P1 or 2
It is relatively easy to apply only to the pillars P1 and P3 of the book.
Therefore, in practicing a beginner, it is possible to determine that the swing motion is normal when only the pillar P1 on the through hole h1 at the ball position and the pillar P2 in the backswing direction are hit. Alternatively, it is possible to determine that the swing motion is normal when only the pillar P1 on the through hole h1 at the ball position and the pillar P3 in the flight direction hit. Then, as you improve, practice by hitting the three pillars P2, P1, P3.

In the above embodiment, the distance between the through hole h1 at the ball position and the through holes h2 to h6 at the flight direction or the through hole h1 at the ball position and one or a plurality of through holes h7 in the backswing direction. The interval between and can be set arbitrarily. In the embodiment, the dimension from the through hole h1 at the ball position to the right end of the substrate 1 is 30 cm, and the through hole h at the ball position is
1 to the through hole h7 in the backswing direction is 1
It is 5 cm.

1 from the through hole h1 at the ball position in the flight direction
20 cm to the second through hole h2, each through hole h2
・ The distance between h3, h4, h5, and h6 is 7 cm. The dimension from the through hole h1 at the ball position to the left end of the substrate 1 is 60c
m. The front-back dimension of the substrate 1 is 50 cm.
The board thickness of the substrate 1 is preferably about 6 to 10 mm.

It is suitable for the substrate 1 to be somewhat elastic such as a rubber mat, but it is sufficient if it is plate-like and the material is not particularly limited. The size of the substrate 1 may be such that it can stand and swing on the substrate 1, or it can stand and swing outside the substrate 1.

Each of the pillars P1 to P3 is capable of maintaining a standing state at all times so that the top end thereof is not damaged even if it is struck by the club head and does not fall down due to being struck. A material with high flexibility is good. Therefore, rubber or soft synthetic resin is suitable. In addition, each of the columns P1 to P3 is more flexible when it is formed into a hollow cylindrical shape.

The height of each pillar P1 to P3 is the lowest pillar P1.
Is 4 to 6 cm, the middle height pillar P2 is 6 to 7 cm, and the tallest pillar h3 is 10 to 15 cm. A structure in which a portion corresponding to the club head is attached to the upper end of a metal coil spring can also be used.

An example in which a plurality of through-holes h2 to h7 are opened in the substrate 1 so that the installation positions of the flexible columns P2 and P3 can be selected has been described, but the same direction as the arrow line 2 is shown on the arrow line 2. It is also possible to form a long slit at the end. If the slit width is set to the same size as the diameter of the through holes h2 to h7, the columns P2 and P3 can freely slide left and right in the slit, which is different from the case where a plurality of independent through holes h2 to h7 are opened. Thus, the positions of the pillars P2 and P3 can be continuously selected or moved.

Therefore, since it may be a slit or a plurality of independent through holes h2 to h7 may be formed, these can be collectively referred to as "circular or elongated through holes".

In practice of swinging, the player swings while standing on both sides of the reference line 4, but in the case of a right-handed person, standing backwards before the arrow line 2 and in the case of a left-handed person,
Behind the arrow 2 and stand in this direction.

When the result of the practice by the swing practice device of the present invention is improved, a tee is set up in the through hole h1 at the ball position, a real golf ball is placed on the tee, and the ball is actually hit. You can also practice.

[0040]

As described in claim 1, two or three flexible pillars are erected on the right and left straight lines on the substrate, and one of the pillars stands in front of the swinging club. At the position of the ideal trajectory drawn by the club head when
Since the height of each pillar is changed so that the tops of the pillars of the book are located, the club head hits the tops of the two or three pillars when an ideal or normal swing motion is performed,
It can be easily determined that the hit ball was supposed to fly straight. Therefore, by practicing so that the club heads hit the top ends of the two or three pillars, the hitting ball can be improved so as to fly straight. Moreover, since this swing trainer has a simple structure and shape, it can be manufactured at low cost.

According to a second aspect of the present invention, each of the pillars is integrally fixed on a support board while standing vertically, and the pillars are inserted into the substrate from the bottom to the top. Since each hole has a circular or elongated through hole,
The desired arbitrary position of the through hole can be selected to stand and the standing position can be freely changed. Further, since the substrate is covered on the support plate at the lower end of each pillar and the support plate of the pillar is pressed by the weight of the substrate, each pillar can be stably stood.

According to a third aspect of the present invention, it has a substrate for standing two or three flexible columns in a straight line on the left and right,
Since through holes for inserting and supporting the above-mentioned two or three columns are formed in a straight line on the left and right sides of this substrate, if two or three columns are prepared, the circular shape of the substrate can be obtained. Alternatively, it is possible to practice the swing simply by inserting two or three columns into the elongated through holes and standing up.

According to a fourth aspect, two or three flexible columns are erected on the right and left straight lines on the substrate, and one of them is
When swinging a club while standing in front of a pillar of a book, practice swinging so that the club head touches the tops of the above-mentioned two or three pillars, and correct the swinging motion so that the hit ball flies straight. You can do or modify it. Therefore, it becomes a correct practice of the swing motion, and the improvement becomes faster.

As described above, by using the swing practice device for golf of the present invention, it is possible to practice swing practice simply by preparing a substrate having a simple structure and two or three flexible columns.
Moreover, an inexpensive swing practice device can be realized. Also, instead of using a golf ball where the hit ball actually flies, it is practice to hit the top end of the flexible pillar with the club head,
Since the flexible pillar does not move or fall, it only vibrates in a standing state, so that it is possible to practice efficiently and easily without any troublesome special operation.
