Description

Detailed Description of the Invention The present invention allows a person to sit on a rotating disk in an upright position, and forces the person on the disk by applying periodic forward and reverse rotational motion (swinging motion) to the disk. The purpose is to give an excellent effect to the body by giving moderate twisting motion to the body, especially to the lower back and back.

Conventional health and beauty equipment that gives torsional motion to the human body on a disk does not use an external power source such as a motor, but uses the leg strength of the person on the disk.
There are some systems that spontaneously give a rocking motion to a rotating disk. However, with this method, the whole body moves with the movement of the legs, and the lumbar region and back vertebrae do not produce very effective twisting movements, and the rotation angle of the rotating disc is adjusted by one's own effort, so the rotation angle is adjusted appropriately. However, it had the disadvantage that it could not be continued for a long time due to fatigue.

The present invention eliminates the drawbacks seen in the above-mentioned conventional examples, and one embodiment will be described in detail below with reference to the accompanying drawings. In FIG. 1, 1 is a fixed base, 2 is an axial gap type motor (hereinafter simply referred to as a motor) equipped with stators 4 on both sides of a rotor 3, and the rotor 3 has a rotor shaft 5. It is fixed in an appropriate manner.

The tip of the rotor shaft 5 is connected to an input gear 7 of a speed reduction mechanism 6 composed of a plurality of gear trains.
The output gear 9 is decelerated and torqued up and transmitted to the output gear 9. Further, a swing shaft 10 is fixed to the output gear 9 by an appropriate method, and a rotating disk 11 is attached to the other end of the swing shaft 10. Reference numeral 12 denotes a thrust load receiving bearing provided on the upper surface of the fixed base 1, which contacts the lower surface of the rotating disk 11 and supports the rotating disk 1.
1 is slidably supported. Reference numeral 13 denotes a gear box containing the gear train 6, and is fixed to the fixed base 1. 14 is a gear shaft that rotatably supports the intermediate gear 8.

Reference numeral 15 indicates a plurality of mounting legs for fixing the motor 2 to the fixed base 1, and reference numeral 16 indicates a torsion bar for fixing the upper body of a person standing on the rotating disk 11 with his/her hands.

17 is an opening/closing means provided concentrically on the bottom surface of the rotating disk 11, and includes two different magnets 17a and 17 provided at an angle corresponding to the rotation angle A° of the rotating disk 11.
Consists of 7b. Reference numeral 18 denotes a switching element such as a self-holding reed switch, which is opened and closed by the opening and closing means.

Based on the above configuration, the next operation is shown in Figures 2 and 3.
This will be explained using figures.

In FIG. 3, 19 is a capacitor for starting and operating the motor 2, and 20 is a motor reversal switch, which is a bidirectional three-terminal control rectifier element 21, 21' for reversing the motor 2 to forward or reverse rotation. Roll call the gate. Reference numeral 22 indicates a relay for switching the contacts of the switch 20.

Now, in the state shown in Figure 2, main switch 2
3, the switching element 18 is in the OFF state, so the relay 22 does not operate, the switch 20 remains on the NC side, and the gate of the element 21 is called and becomes conductive, and the motor is turned on. 2 rotates to the right, for example, and the rotary disk 11 also rotates in the direction of arrow a in FIG.

Next, the magnet 17 fixed to the rotating disk 11
When a reaches the vicinity of the switching element 18, the contact closes. When the contacts of switching element 18 are closed, relay 22 is activated and switch 20 is activated.
Switches to the NO side, the element 21' becomes conductive, and the motor 2 is reversed and the rotating disk 11
It also switches to the arrow b side in FIG.

At this time, since the switching element 18 is of a self-holding type, it maintains this state until the other magnet 17b approaches. Next, when the magnet 17b of a different polarity approaches, the switching element 18 is turned off again, and the motor 2 and rotating disk 11 are again reversed as described above.

On the other hand, in FIGS. 4 and 5, two pairs of opening/closing means (17a and 17) are shown on different concentric circles of the rotating disk 11.
b, 17c and 17d) with angles A° and B°, respectively, and two switching elements 18, 18' facing the two pairs of opening/closing means. ing. FIG. 5 is a circuit diagram of the configuration shown in FIG. 4, in which the switching element 18 or 18'
The rotating disk 11 is connected to operate either one of the two, and as described above, the rotating disk 11 performs a reciprocating rocking motion with a rotation angle of A° or B°.

In addition, in this system, even if only one switching element 18 is used and the element 18 is moved to the position shown in FIG. Exactly the same effect can be expected even if the positional relationship of the pair of opening/closing means 17 is mechanically adjusted.

As is clear from the above examples, the health and beauty equipment of the present invention has the following excellent effects.

1 When a person stands upright on a rotating disc, the rocking motion of the rotating disc is transmitted to the legs and lower body of the passenger, giving appropriate twisting motion to the lower back and back vertebrae, which has excellent health effects. can be raised.

2. Since the forward and reverse rotation angles of the rotary disk are controlled by the opening/closing means and switching elements corresponding to the rotation angles, reliable operation can be achieved.

3. By appropriately changing the positions and numbers of the opening/closing means and the switching elements, it is possible to vary the rotation angle of the rotary disk, and the degree of twisting of the body can be varied.
