Abstract

PURPOSE: To generate a very high effect of training and strengthening an ankle and knee and also strengthening the muscular force of the feet and waist by installing a ball caster and a screw foot in the center of discs confronting each other up and down, attaching a slip stopper to the oversurface of the upper disc, and consolidating them in a single piece. CONSTITUTION: A ball caster 2 and a screw foot 3 are installed in the center of discs 1, 1' confronting each other up and down, and these are consolidated in a single piece, and a slip stopper 4 is attached to the oversurface of the disc 1. When ankle training is made with this tool, feet 5 are placed on the disc 1 in such a way that they are open to a certain extent, and the body weight is shifted to any side, which causes the disc 1 to incline in the condition that its point in the down position touches the lower disc 1'. If the body weight is further moved, the inclined surface shifts to that side, and continued performance of this motion generates a circular motion 6 of the inclined surface round a fulcrum through the action of the ball caster 2. Accordingly the ankles 5 make a circular motion automatically while the body weight is loaded unchangedly in compliance with the variation of the inclined surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary motion tool for an ankle in which a ball caster and a screw type foot are attached to discs which face each other vertically and which are integrated with each other, and an anti-slip is attached to an upper disc upper face. is there.

[0002]

2. Description of the Related Art Heretofore, there has been an exercise tool for placing the entire body and moving it greatly.

[0003]

However, this has the following drawbacks. (A) The lower part had a hemispherical shape, and I could not move my body unless I grasped it on the railing above. (B) Even though the whole body could be exercised, it was not possible to exercise the ankle or a specific part. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problem] Discs (1) facing each other vertically
A ball caster (2) and a screw type foot (3) are attached to the center of (1 ') to integrate them, and a slip stopper (4) is attached to the upper surface of the disc (1). The present invention is an ankle rotating exercise tool having the above-described configuration.

[0005]

[Function] When the ankle (5) is placed on the disc (1) with the ankle (5) slightly open, and the weight is moved in either direction, the disc (1) is inclined and the disc (1) is inclined. An inclined surface is formed such that one lower corner is attached to the disc (1 '). Then, when the weight is further moved, the inclined surface moves in the moving direction, and the continuous movement of the weight allows the circular movement (6) of the inclined surface around the fulcrum of the ball caster (2). For this reason, the ankle (5) on which the user rides corresponds to the change in the inclined surface, so that the ankle (5) automatically causes the rotational motion while keeping the weight.

[0006]

Embodiments of the present invention will be described below. (A) Attach the ball caster (2) and the screw type foot (3) to the center of the discs (1) and (1 ') facing up and down, and integrate them to prevent slipping on the top face of the disc (1). Attach (4). The present invention has the above-described structure, and when this is used, when the ankle (5) is mounted on the disc (1) with the ankle (5) slightly open and the weight is moved in either direction, the disc (1)
Is inclined, so that one lower corner of the disk (1) forms an inclined surface attached to the disk (1 '). Here, when the weight is further moved, the inclined surface moves in the moving direction, and the continuous movement of the inclined surface allows the circular movement (6) of the inclined surface around the fulcrum of the ball caster (2). For this reason, the ankle (5) on which the user rides corresponds to the change in the inclined surface, so that the ankle (5) automatically causes the rotational motion while keeping the weight.

[0007]

Since the ankle corresponds to the inclined surface, the movement of the weight automatically causes the rotational movement, and the knee also causes the flexion and extension movement. Moreover, since the inclination angle can be changed by the screw type foot (3), it can be applied to various ankles, and the slip stopper (4) prevents the slide from falling. By the above-mentioned usage, it is extremely effective in strengthening the training of the ankle and knee and strengthening the muscular strength of the lower back. Moreover, the present invention is easy to use, can be manufactured in large quantities with inexpensive materials and simple manufacturing processes, and can be made beautiful in appearance, so it is also fun to use as a play equipment.

Claims (1)

[Claims] 1. A ball caster (2) and a screw type foot (3) are attached to the center of the discs (1) (1 ') facing each other in the vertical direction, and a slip stopper (4) is attached to the upper face of the disc (1). Attached to this, this is an ankle rotating exercise tool.
