Each of the outer arcuate guide portions 4d of the club head is represented, and the corresponding inner arcuate guide portions 2c, 3c, 4c and outer arcuate guide portions 2d, 3d, 4d are connected by a number of straight lines at approximately equal intervals to form a club shaft. The hollow part 10 is formed by cutting out the center of the surface 1 from the outside of the inner arcuate guide parts 2c, 3c, and 4c.

[Example] An example of the present invention will be described with reference to the accompanying drawings.

As shown in Figures 5, 9, and 10, a surface 1 is provided that gradually slopes backward as it goes from the outside to the center and is horizontal to the club shaft and arms, and from the center of the surface 1 to the upper part. The main body 1a, which is tilted forward at an appropriate angle and provided with a cavity 10 in the center, is placed in a recess 17 on the front side of the base 11 with a backward tilt, and is held by a support member 20 so as to be able to adjust the tilt angle. Note that the main body 1a is preferably divided into upper and lower parts from the center, and the upper part of the main body 1a from the center is provided so as to be adjustable in angle.

A surface 18 representing the locus of the club face is provided on the entire or part of the periphery of the main body 1a, and this surface 18 is fitted into the recess 17.

The club face position 15 at address is shown in the center of the recess 17, and a recess 16 with a mat 19 is provided in front of it, and a shoulder rest 12 is provided on one side of the recess 16 in a height adjustable manner. It is erected.

This shoulder rest 12 determines the position of the shoulder at the top of the backswing.

A pair of leg rests 13 are provided on the base 11 at the rear of the main body 1a.

The surfaces 1, 18 of the main body 1a are provided with the tracks shown in FIG. 6, which are represented by the drawings in FIGS. 1-4.

The applicant has proposed that when the center of gravity of the body during the downswing is located on a vertical line of the center position 7 of the main body 1a, the center of gravity of the body during the backswing shifts to the left side of the center position 7 when viewed from the front, and the body during the focus-through moves. Focusing on the fact that a swing in which the center of gravity moves to the right side of the center position 7 is important as a swing performed with the whole body including the hips with the head as the axis, based on this, The center position 7 is set slightly above and to the left of the address grip position when viewed from the ground. A vertical line 3 for downswing passing through this center position 7, a vertical line 2 for backswing located to the left of this vertical line by a predetermined distance, and a vertical line for follow-through located to the right of said vertical line 3 by a predetermined distance. 4 will be provided.

Next, the length of the club shaft is constant during the swing, and the trajectory of the grip and the trajectory of the club head are larger during backswing and follow-through than during downswing, and are higher during follow-through than during backswing. Focusing on this, a lower point 3b is provided below the center position 7 on the downswing vertical line 3, and an upper point 3a is provided near and above the center position 7.
A lower point 2b is provided near and below the center position 7 on the vertical line 2 for backswing, and an upper point 2a is provided at the same interval as the upper and lower points 3a, 3b, and the center position 7 on the vertical line 4 for follow-through is provided. The lower point 4b is provided at the same height as the upper and lower points 3a, 3.
Upper points 4a are provided at the same interval as b.

Next, centering on the upper point 2a of the left vertical line 2, an inner arcuate guide portion 2c is shown with a diameter connecting the upper point 2a to the grip position 5b at the address, indicating the grip locus during backswing, and its lower point 2b Centering on , an outer arcuate guide portion 2d showing the locus of the club head with a diameter connecting the lower point 2b to the club head position 5c at address is shown from the address to the top.

Centered on the upper point 3a of the central vertical line 3, it represents an inner arc-shaped guide portion 3c with a diameter connecting the upper point 3a to the grip position 5b at address, which indicates the grip trajectory during the downswing, and also connects the lower point 3b to the club head at address. The outer arcuate guide portion 3d, which shows the locus of the club head, is represented by the diameter connecting the positions 5c from the address to the top.

Centering on the upper point 4a of the right vertical line 4, the diameter connecting the upper point 4a to the grip position 5b of the address represents the inner arc-shaped guide portion 4c during follow-through, and the diameter connecting the upper point 4a to the grip position 5b of the address represents the inner arc-shaped guide portion 4c at the time of follow-through. The outer arcuate guide portion 4d, which shows the locus of the club head with a diameter connecting the club head position 5c at address, is shown from the address to the top.

Each of the inner arcuate guide portions 2c, 3c, 4c and the outer arcuate guide portions 2d, 3d, 4d are connected by a large number of linear guide portions 5 that represent the locus of the club shaft at approximately equal intervals. It shows a trajectory 6 of the club face that opens and closes at a constant angle at the tip.

If the hollow portion 10 is removed by notching from the outside of the inner circular guide portions 2c, 3c, and 4c in the trajectory shown in FIG. 1, the inner circular guide portions 2c, 3c, and 4c will not exist The trajectory is shown in FIG. 6, and this trajectory is represented on the surfaces 1 and 18 of the main body 1a as shown in FIGS. 9 and 10. In this case, the size of surface 1 may be set to be large or small depending on the length of the club shaft, but the relationship between each point 2a, 2b, 3a, 3b, 4a, 4b with respect to the center position 7 is determined by the length of the club shaft. , is almost constant regardless of height and arm length.

Also, a linear guide portion 5 indicating the club shaft and outer arcuate guide portions 2d and 3 indicating the trajectory of the club head.
The intersection points with d and 4d are equally spaced, but the intersections between the linear guide portion 5 and the inner arcuate guide portions 2c, 3c, and 4c are slightly denser in the center of the inner arcuate guide portions 2c, 3c, and 4c. It gradually becomes a little coarser.

Also, during backswing, the club face is open to an average of 90 degrees, and during focus through, the top is closed to an average of 180 degrees, and the club shaft is in a substantially horizontal state.

In Figures 1 to 4 and 6, the white dot indicates the center position 7, the vertical chain line indicates the center line 8, and the clubshaft at address is slightly inclined to the right of the center line 8 when viewed from the front. There are linear guide portions 5a showing the ball positions 9, respectively.

Also, the angle a of surface 1 in Fig. 5 is about 50 to 70 degrees, and the angle b
is preferably about 119 degrees, and angle c is preferably about 160.5 degrees. The angles a and b can be adjusted by letting the main body 1a lie back or raise it, and the angle c can be adjusted by letting the divided upper half of the main body lie down or raise it. Also, the position of c will shift downward as the golf club becomes shorter.

This angle c is related to the speed at which the face opens to 90 degrees during backswing, and is the first
If the face is fully opened 90 degrees during the early backswing as shown in Figure 1A, then c as shown in Figure 11B.
As the angle of
As shown in Figure B, the angle c becomes smaller, and as shown in Figure 13A
When the face is fully opened at the top, the angle c becomes the smallest.

Now, centrifugal force is not generated in an elliptical trajectory with one center point 7 in FIG. 1, but centrifugal force is generated in each of the back, down, and follow swings because of the circular trajectory.

However, due to body shape, the so-called square swing in the golf swing is different from the circular motion of a machine, so it is impossible to swing from one center in one circle or to roll up or down the club while twisting.

Each golf swing has two center points. The two points are the center of the inner circle that shows the trajectory of the grip of the club, and the center of the outer circle that shows the trajectory of the club head.The two points are the center of the inner circle that shows the trajectory of the club's grip, and the center of the outer circle that shows the trajectory of the club head. It can be done.

That is, the arcuate guide portions 2c, 2d, and 3 for back-down and follow-swing, respectively.
Perpendicular lines 2, 3, parallel to c, 3d, 4c, 4d,
4, the centers of the upper and lower two points 2a, 2b, 3a, 3b,
4a and 4b, and as the weight shifts during the swing, the vertical lines 2, 3, and 4 move horizontally from 2 to 3, and from 3 to 4, and from the center points 2a, 2b to 3.
a, 3b and 4a, 4b, the golf swing becomes an elliptical trajectory as a whole.

In this case, center points 2a, 2b and 3a, 3b, 4
It is preferable that the vertical spacing between a and 4b is approximately the same. Further, it is preferable that the center 7 of the entire ellipse and the central vertical line 3 substantially coincide with each other.

Further, the rotation angle of the club face is opened and closed at equal intervals, and after being fully opened, the club face remains fully open while moving.

Therefore, as shown in FIG. 9 and FIG.
Stand in the center of the back and hold the golf club 1
It is positioned on the surface of surface 1 of A and swings along the swing trajectory represented on surfaces 1 and 18.

In other words, since the display shows the outer arcuate guide portions 2d, 3d, and 4d indicating the trajectory of the club head, the linear guide portion 5 indicating the trajectory of the club shaft, and the trajectory of the angle of the club face surface, the golfer can swing along the inclined plane 1. By practicing this, each circular trajectory will move smoothly from the backswing to the downswing to the forward through as the weight shifts, resulting in a swing with an elliptical trajectory that can fully utilize centrifugal force.

Therefore, this type of swing is a natural swing in which the head does not move and the entire body is twisted around the head, making it easy to master the ideal swing. When practicing, it is effective to place mirrors on the left and right sides of the front of the main unit.

Note that three arcs representing the trajectory of the club head during back, down, and follow swings and a number of straight lines representing the trajectory of the club shaft may be formed from rods and connected to form the framework. .
