Abstract

PURPOSE: To enable the body weight shifting exercise in a nearer state to the actual skiing movement by giving rotation either to the right or to the left against a body shaft through a main shaft by the body weight shifting user, and making a slide shaft rotatable not only radially but also before and behind. CONSTITUTION: When the user rotates a main shaft 4 to the left by shifting his body weight, foot seats 9 are rotated, against torsional force of a pushing coil spring 11, by the rotation of the user's feet. However, the foot seats 9 are stabilized by reactive force which is generated, in the direction always toward the specified state, by the torsional force of the pushing coil spring 11. Simultaneously with their rotation, the right foot seat 9 is slid, against the force of the pushing coil spring 11, by the force of the user so that both right and left feet can be positioned with a slip before and behind in a nearly actual skiing movement. When the user returns the main shaft 4 to the middle, he is pushed forward, without giving force to the right foot seat 9, by righting force of the pushing coil spring 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski training device for practicing weight transfer by reproducing the movement of a skier while sliding.

[0002]

2. Description of the Related Art Conventionally, there is a ski training device for practicing weight shift such as Proskifit S830 (manufactured by TUNTURI), which is a ski training device as shown in FIGS. 8 and 9, for example. In FIG. 8, a main shaft 21 is provided on a main body shaft 23 fixed to a main body 22 so as to be rotatable in the left and right horizontal directions,
A spindle base 24 is fixed to the tip of the spindle 21. As shown in FIG. 9, a footrest 26 is provided on the main spindle base 24 so as to be rotatable in the radial direction via a slide shaft 25 for following the inclination of the foot. A pulling coil spring 27 is connected between the main shaft 21 and the main body 22, and a handle 28 is provided on the main body shaft 23.

In such a ski practice apparatus, the user first holds the handle 28 with both hands and stands on the footrest 26 with both feet. Then, against the pulling coil spring 27, the weight of the footrest 26 is moved horizontally by the user's own weight movement to practice weight movement. At this time, the footrest 26 follows the movement of the foot and rotates in the radial direction. Further, techniques relating to skiing practice, etc. are proposed in Japanese Examined Patent Publication No. 59-174175 and Japanese Utility Model Publication No. 63-181806, and techniques relating to various sports practices are disclosed in JP-A-5-216392.
It is proposed in Japanese Laid-Open Patent Publication No. 10-15772.

[0004]

However, in the above-mentioned conventional ski training device, the footrest can be rotated in the radial direction, but the foot cannot be slid back and forth. Therefore, it was not possible to practice weight transfer effectively, which is very different from actual skiing. In addition, since the footrest rotates freely, when the user gets on and off the footrest, the footrest must be turned upward (hereinafter referred to as a regulated state), and the footrest is unstable. Therefore, there was a case where I was accidentally injured.
Furthermore, even during the practice of weight transfer, the footrests were unstable, so effective training could not be performed.

The present invention has been made in view of the above problems. By sliding the footrest, the user can practice weight transfer in a state closer to the actual ski operation, and the footrest is always kept when not in use. The purpose of the present invention is to provide a ski practice device that is in a regulated state and has a stable footrest.

[0006]

In order to achieve the above object, a ski training apparatus of the present invention comprises a body installed on the floor,
A main body shaft fixed to the main body and provided with a handle, a main shaft horizontally rotatably provided on the main body shaft, a tension coil spring provided between the main shaft and the main body, and the main shaft. A main shaft base, a pair of slide shafts that are inserted into the main shaft base so as to be rotatable and slidable in the radial direction longer than the main shaft base, a flange provided at an end of the main shaft side of the slide shaft, and a slide shaft. And a footrest provided at the end of the body opposite to the main shaft.

Preferably, a coil spring is provided between the main shaft base and the flange of the slide shaft, between the footrest and the main shaft base, between the footrest and the main shaft base, and between the main shaft base and the flange. It has a different structure.

Further, the coil spring is fixed to the main shaft base and the flange or to the footrest and the main shaft base, if necessary.

[0009]

According to the ski practice device of the present invention having the above-mentioned structure, the main shaft is rotated to the right or left in the horizontal direction with respect to the main body shaft by the movement of the weight of the user, and the slide shaft is rotated in the radial direction. By sliding back and forth, the footrest is rotated and moved back and forth, and the user's foot is rotated by the inclination of the body and the left and right feet are slid back and forth to perform an operation close to an actual skiing operation. Also, the flange prevents the slide shaft from coming off the main shaft base, and the tension coil spring always pulls the main shaft in the axial direction of the main body so that the main shaft is located at the center of the main body.

A coil spring between the main spindle base and the flange pulls the footrest toward the main spindle base side (in the case of a push coil spring) or pushes out the footrest from the opposite main spindle base side (in the case of a tension coil spring), a footrest. The coil spring between the and the spindle base pushes the footrest to the opposite main spindle base side (in the case of a push coil spring) or pulls the footrest to the main spindle base side (in the case of a tension coil spring), and between the footrest and the spindle base. A coil spring between the spindle base and the flange positions the footrest at approximately the center of the spindle base side and the anti-spindle base side (for both push and tension coil springs),
When not in use, the two feet are always aligned and in a fixed position.

Further, a coil spring fixed to the spindle base and the flange or to the footrest and the spindle base biases the footrest in the radial direction so that the footrest is always in a prescribed state when not in use. By adding an additional force to the to prevent it from freely rotating, it is possible to stabilize it during use and when getting on and off.
