The former prevents the right arm from moving to the rear and right side of the body at address during the backswing in the golf swing, and prevents the left shoulder from dropping below the plane perpendicular to the axis of rotation of the upper body near the spine, thereby improving the form. It is designed to maintain accuracy, and a column with a rotating shaft is attached to the supporting material, and a member for positioning the rotating shaft and the column is attached, and an L-shaped member and a deformed L-shaped member are attached to the column. . The latter is a training device for preventing hip sway during the golf swing.

[Problem to be solved]

In all of the above-mentioned conventional examples, the rotating shaft rotates smoothly during the turning movement of the human body, in other words, the rotating shaft is configured to rotate with the same force at any part during the turning movement. ing. Therefore, although it is useful for forming the correct golf swing form, it does not allow one to learn where to put effort. Furthermore, it was not intended to train muscle strength, but merely to correct form.

Therefore, this invention provides a turning training machine for golf swings, etc., which allows the human body to acquire the correct form when performing turning movements such as a golf swing, and also allows the user to find a place to apply force, and which is also useful for muscle strength training. The purpose is to provide

In order to achieve the above-mentioned object, the present invention provides a connector member for transmitting the rotational movement of the human body to the rotational shaft, and a part of the circular arc of the rotational shaft that rotates in accordance with the rotational movement of the human body has a connector member that transmits the rotational movement of the human body. It also requires a lot of force to rotate.

[Effect]

In this invention, by changing the settings of the part that requires more force to rotate the rotation axis, golf
It is possible to set a rotation movement that suits the purpose of tennis, table tennis, etc., and it is also useful for obtaining the correct form, where to apply force, and for muscle training.

〔Example〕

Preferred embodiments of the present invention will be described below with reference to the drawings.

In the embodiment shown in FIG. 1, a connector member 2 is provided to the rotating shaft 1 for transmitting the rotational motion of the human body. The rotating shaft 1 is rotatably supported by bearings 3 and 4.
4 is attached to the attachment member 5. The mounting member 5 is mounted on a frame 6 having a concave shape. The frame 6 is attached to a bracket 8 provided on the base body 7 so that its inclination angle can be adjusted.

A rotating body 9 is attached to the lower end of the rotating shaft 1. The central axis X of the rotating body 9 and the central axis Y of the rotating shaft 1 are eccentric as shown in FIG. A plate 1 is fixed to the lower end of the rotating shaft 1, and a plate 11 fixed to the rotational center shaft 10 of the rotating body 9 is fixed to this plate 1', and a plate 11 fixed to the rotational center shaft 10 of the rotating body 9 is fixed to the plate 1'. One-way clutch 12
so that the rotation center shaft body 10 and the rotor body 9 are connected only during the turning movement in the direction of hitting the ball, and the connection between the rotation center shaft body 10 and the rotation body 9 is broken during the rotation movement in the opposite direction. It has become. Further, a belt 13 is wound around the outer circumference of the rotating body 9.

As shown in FIG. 1, the connector member 2 attached to the rotating shaft 1 has the upper end of a cylinder 14 attached to the rotating shaft 1 adjustable in height fixed to the lower surface of a plate 15. A plurality of attachment holes are formed in the longitudinal direction of 15, a ball 16 is attached at a desired location, and a pipe 17 is provided to be attached to the ball 16 in a height-adjustable manner.
A U-shaped member 18 is attached to this pipe 17. By adjusting the height of the pipe 17, adjusting the attachment position of the ball 16 to the attachment plate 15, or adjusting the cylindrical body 14 up and down, it is possible to match the shape of a human body that performs a turning movement. In this embodiment, both ends of the U-shaped member 18 are held between the arms of the person who is about to swing, and when performing a golf swing, for example, the U-shaped member 18 is inserted between the two ends of the U-shaped member 18. ;t! -J
L/16. Installation vjlI 5. The movement of the human body is transmitted to the cylindrical body 14, and the rotating shaft 1 rotates.

In the present invention, as an example of requiring more force to rotate a portion of the arc of the rotating shaft 1 that rotates with the turning movement of the human body than other portions, in the illustrated embodiment, As shown in FIGS. 3 and 4, a belt 13 is wound around the outer circumference of the rotating body 9, both ends of the belt 13 are supported by clamps 19, and rollers 20
The winding is such that it can change state.

In the state shown in FIG. 3, the belt 13 is slightly away from the outer periphery of the rotating body 9, and when a human body makes a golf swing, the axes of the rotating body 9 and the rotating shaft 1 are eccentric just before impact. Due to this, the belt 13 winds tightly around the rotating body 9.

Therefore, more force is required to rotate a portion of the arcuate trajectory of the rotary shaft 1 than other portions of the arcuate trajectory. Therefore, since turning motion in this range requires more force, muscle strength training can be performed, and the golf swing can naturally master the power reserve before impact. The roller 20 in FIG. 3 is adjustable and can be moved to the left to require more force.

FIG. 5 shows the locus of a golf swing, and the part of the arcuate locus of the rotary shaft 1 indicated by the symbol 1 requires more force to rotate the rotary shaft 1 than other parts. ing.

Also, this part A only acts on the trajectory from the top of the swing to the down, impact, and follow, and during the backswing, the one-way clutch 12
Due to this action, no force is required to rotate the rotating shaft 1.

As for the connector member 2 for transmitting the rotational motion of the human body to the rotating shaft 1, the configuration shown in FIG. 1 is an example, and it is also possible to adopt another configuration.

Furthermore, although this illustrated embodiment assumes a golf swing, it is of course possible to apply this practice device to the action of hitting a ball in tennis, table tennis, or the like. Furthermore, a means for configuring the part A shown in FIG. 5 to require a large amount of force to rotate the rotating shaft 1 is also possible by eccentrically connecting the rotating shaft 1 and the rotating body 9 and connecting the one-way clutch 12. In addition to the configuration in which the belt 13 is used, an electronically controlled brake mechanism is provided on the rotating shaft 1, and the brake is applied only to the part A when the rotating shaft rotates in the direction of the half-hour hand in FIG. A similar purpose can also be achieved by

〔effect〕

As explained above, according to the present invention, a connector member for transmitting the rotational movement of the human body is provided to the rotational shaft, and one part of the arc of the rotational axis that rotates with the rotational movement of the human body is connected to the other part. Since it requires a lot of force to rotate, it is not only useful for simply correcting the form, but also allows you to learn where to apply force, and is also useful for strength training.
