2. Description of the Related Art As conventional techniques of this kind, there have been small seesaws for reciprocating ankles, reciprocating lateral plates, and the like.

[0003]

SUMMARY OF THE INVENTION The above-mentioned prior art is only for tilting the ankle in the lateral direction of the body, and the ankle is evenly distributed in all directions without rotating the body, so-called "miso shaving motion". Until now, there has never been a thing that can be exercised by inclining to move the legs and feet evenly in all directions.

In order to eliminate the above-mentioned problems, the present invention achieves strengthening of the lower back and activation of central nervous system by tilting the ankle in all directions without rotating the body. With the goal.

[0005]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is to provide a pedestal having a plurality of rotatably engaged between the side grooves of two large and small flat rings on the upper surface of a hollow pedestal containing a motor. A non-axial rotating centering member is laid flat, a rotating ring is laid flat on the centering member so as to be rotatable by the rotational force of the motor, and tilted along with the rotation on the inclined upper surface of the rotating ring. The oscillating plate is concentrically provided obliquely with a rotary centering member similar to the centering member interposed, and its center is fixed to the upper part of a rotation preventing member such as a universal joint or a spring erected on the pedestal. I was able to achieve it by doing what I did.

[0006]

The rotating ring can be rotated by the rotational force of the motor through the shaftless centering member installed on the upper surface of the hollow pedestal containing the motor. Then, by fixing the central portion of the rocking plate that tilts along the rotationally inclined upper surface of the rotary ring to the upper part of a rotation preventing member such as a universal joint or a thick spring that is erected on the pedestal, the rocking plate Without rotating, it can be tilted in all directions in a so-called "missor-sliding motion" type, and it does not fall off deliberately.

[0007]

EXAMPLES Examples will be described with reference to the drawings. First, the basic configuration of the present invention is as shown in FIGS.
On the upper surface 1a of the hollow pedestal 1 in which the motor M rotating at a rotation speed of about 600 RPM is installed, two large and small flat rings R are provided.
A non-axial rotation centering member RB composed of a large number of rotators B and the like which are rotatably engaged between the respective side grooves is laid flat. The rotary ring 2 is laid flat on the centering member RB so as to be rotatable by the rotational force of the internal gear G2 meshed with the output gear G1 of the motor M, and the inclined upper surface 2a of the rotary ring 2 is provided.
An oscillating plate 3 that tilts with its rotation is concentrically provided obliquely with a rotary centering member RB similar to the centering member interposed therebetween.

Further, the prismatic portion 4c of the well-known universal joint 4 having the XY pivots 4a and 4b as shown in FIG. 3 fixedly hung on the inner surface of the center portion O is fixed to the base plate 1 as shown in FIG. The foot swing exercising device according to the present invention, which is an example of a member for preventing the rotation of the oscillating plate 3, is constructed by deeply inserting the oscillating plate 3 into the square hole pipe 4d standing on the upper surface.

Next, as an example of the non-axial rotation centering member RB, two large and small flat rings R, R as shown in FIG. 2 are formed by die-casting a metal such as aluminum.
It is well-known that each of the rings is rotatably fitted and contacted with each other by a large number of trochanters B such as steel balls that are rotatably engaged with each other between the side grooves of the large ring through ball insertion holes on the outer periphery of the large ring. Use the one.

The ball insertion hole of each of the rotary centering members RB is closed with a male screw after the ball is inserted, and the upper and lower flat rings R, R are adjacent to the pedestal upper surface 1A, the rotating body 2 and the rotating body 2 respectively. The parts are firmly fixed to the upper surface 2a of the body and the rocking plate 3 by fixing means such as screwing or bonding.

Then, this shaftless rotary centering member RB
A well-known one used for a TV stand turntable or the like can be used as the centering member RB. The centering member RB is a large number (about 50 mm) sandwiched between the side grooves of the large and small metal rings R, R.
Since it is fitted through the trochanters B (~ 100 pieces), the rotation is smooth and sturdy, it does not inadvertently move up and down, and center deviation does not occur.

In each of the above figures, the reference numeral n is a set screw, 3a is a rubber sheet, and each member is mechanically strong and sturdy.
After these are assembled from the state of the exploded sectional view shown in FIG. 2 with the set screw n as shown in FIG. 1, the set screw n is paint-locked, and the gear ratio of each gear G1 and G2 is 1 : Set to about 10.

The configuration of the present invention is as described above, and its operation will be described below. On the horizontal upper surface 1a of the pedestal 1, the rotating ring 2 is rotated by the rotating force of the motor M, and the gear G1 of the output shaft thereof is provided.
The internal gear G of the lower plate 2b of the rotating ring 2 meshed with
By means of 2, it is possible to rotate at a low speed of about 1 rotation per second. This centering of the rotation can be achieved by adopting the well-known rotation centering means by the non-axial rotation centering member RB as described above.

When the rotating ring 2 is rotated at a low speed, the rocking plate 3 on the rotating ring 2 is in the upper right position as shown in FIG. 1 when viewed from the front through the shaftless rotary centering member RB arranged in parallel on the lower surface thereof. After going through the front descent state in Fig. 4 and going to the right descent in Fig. 5,
It is possible to sequentially and repeatedly tilt in all directions from the backward descending state shown in FIG. 6 to the upper rightward state in FIG.

During this operation, the oscillating plate 3 on the rotary ring 2 has the center O of the universal joint 4 as described above.
Since it is fixed to the upper part of the rotation ring, it can be prevented from rotating and can be tilted and swung without rotation following the tilting of the upper surface of the rotating ring 2 in all directions. Moreover, the swing plate 3 does not inadvertently move up and down. Therefore, as shown in FIG. 7A when the ankle a of the person to be trained on the rocking plate 3 is seen from the front, and also when seen from the side, FIG. It was possible to tilt in a non-rotational manner in the "sliding motion" type, and it was possible to promote training of the legs and waist and activation of the central nervous system.

As a member for preventing the rotation of the oscillating plate 3, other than the member of the universal joint 4 of the previous example, for example, FIG.
It is possible to use a tough elastic body such as a sturdy coil spring SP that bends and deforms due to an external force as shown in FIG. 6 or a semi-hard synthetic rubber thick column G as shown in FIG. it can. In addition, the internal gear of the rotating ring 2 G2
Can employ the internal gear G3 of the flat ring R fixed to the lower part of the rotary ring 2 on the small diameter side as shown in FIG.
In each of the above drawings, the same reference numerals as those used in the above-described embodiment indicate the same or equivalent portions.

[0017]

Since the present invention is configured as described above, it has the following effects. The oscillating plate 3 on the inclined upper surface 2a of the rotating ring 2 rotating on the pedestal 1 has its center O
Is fixed to the upper part of the rotation preventing member such as the universal joint 4, so that the inclined upper surface 2a of the rotating ring 2 does not rotate.
Can be smoothly tilted and swung in a non-rotational state in accordance with the tilting of the rocking plate, and the rocking center is not deviated inadvertently, and the rocking plate 3 is not inadvertently moved up and down. The trainee on the moving board 3 has the effect of being able to safely promote the strengthening of the ankle, the training of the legs and waist, and the activation of the central nervous system.
