- the uppermost swivel table 30 makes a revolving motion without changing its direction. This is a swivel motion in which both the first and second turntable devices 11 and 12 do not change their direction, and the motion of the swivel 30 is a combination of the first and second turn motions. That's why. Then, the swivel base 30 can move at the maximum turning radius corresponding to the sum of the turning radii of the first and second turntable devices 11 and 12 at the maximum.
- the movement of the turntable 30 is a combined movement of the first and second turntable devices 11 and 12, and depending on how the force is applied, the turntable 30 can be moved in a complicated manner.

- the user who gets on the swivel base 30 makes the swivel base 30 perform a swiveling motion by using a recoil pressed with a hand on a wall or the like. According to this, it is possible to perform more intense exercise using the entire body than the exercise equipment 85 described above.
- a method may be used in which the assistant swings and turns the swivel table 30 on which the user has entered.
- an auxiliary rod 29a is attached to the fixed base 20 as shown in FIG. 26, and the user moves the auxiliary rod 29a to move the swivel base 30. It may be configured to perform a turning motion.
- a ball portion 29b is provided at the lower end of the auxiliary rod 29a.
- the ball portion 29b is rotatably fitted into a bearing 86 provided on the fixed base 20.
- the auxiliary rod 29a extends upward from the fixed base 20 through a through hole of the swivel base 30. The through hole is provided with some allowance for the auxiliary rod 29a.
- FIG. 27 shows an exercise device having a configuration in which the swivel device 10 and the auxiliary device 87 are combined.
- the auxiliary device 87 is for assisting a person to stand up, and is formed by bending or joining a pipe made of iron or the like into a predetermined shape, and providing a handrail 88 on an upper portion to form a frame.
- the user 28 entering the space provided in the center of the frame can put weight on the handrail 88. For this reason, it is possible to assist people who have a disability in walking function.
- casters 89 are provided below the auxiliary devices 87, respectively. It can be moved by tilting the auxiliary device 87.
- the driving means is manually operated.
- the crank member 60 By rotating the handle 46 in the horizontal plane, the crank member 60 is turned.
- Reference numeral 48 denotes a rotating shaft, which is connected between the handle 46 and the crank member 60 and transmits the rotational force of the handle 46 to the crank member 60. Thereby, a turning motion of the turning table 30 that does not rotate can be obtained.
- the driving means is manually operated.
- the crank member 60 is turned by rotating the handle 46a in a vertical plane.
- 47 is a gear mechanism combining a bevel gear. This converts the rotation in the vertical plane into the rotation of the rotating shaft 48a that stands up and transmits the drive. According to this, it is also possible to obtain a turning motion of the turning table 30 that does not rotate.
- the present embodiment is a plug-in type exercise apparatus.
- a turning table device 10 that generates a turning motion that does not rotate is provided, a fixed thin plate portion 57 extends from a fixed table 20 of the turning table device 10, and a turning thin plate portion 58 extends from the turning table 30.
- the fixed thin plate portion 57 and the turning thin plate portion 58 form an insertion portion 59.
- the fixed thin plate portion 57 and the turning thin plate portion 58 may have surfaces having little frictional resistance and have appropriate rigidity.
- the insertion portion 59 is inserted between the person and the bed 76, and the swivel device 10 is driven. As a result, the same effect as that of the bed described above can be obtained.
- the swivel device according to the present invention is not limited to exercise equipment such as exercise equipment, rehabilitation equipment, physical exercise exercise equipment, etc. for the purpose of maintaining and improving health, as well as a stirrer and a multi-axis rotational motion generator.
- the present invention can be applied to a device, a polishing device, a winding device, a vibration generating device, a force of a mushroom cultivation base, a drawing device, and a movement mechanism of other devices.
