These foot rests 2 and 2 are, for example, sandals or slippers with heels as shown in the figure, or two belts with hook-and-loop fasteners or buckles to secure the instep side so that the soles of the left and right feet can be closely fixed. It may be possible to tighten.

2 to 3 show a drive mechanism of a footrest plate provided in the container casing 1, and 3 is a rod which penetrates the top plate 1a constituting the container casing 1 and has left and right feet. The upper ends of the rods 3 are fixed to the heels of the mounting plates 2 and 2,
A spherical portion 4 having a bulged outer periphery is formed above the middle portion of the spherical portion 4. The spherical portion 4 is supported by a spherical bearing 5 provided on the top plate 1a of the housing 1 and hangs down inside the housing 1. Below the rod 3, it is swingable in all directions with the spherical portion 4 as a fulcrum. Since the present invention intends to rotate both feet around the heel, the distance between the spherical portion 4 and the heel portion of the footrest plate 2, that is, the length above the spherical portion 4 of the rod 3 is The shorter, the better (for example, 1-2 cm).

Reference numeral 6 designates a slide box which is floated in the housing 1.
A bottom plate 6a of the slide box 6 is inserted into and supported by two guide rods 7, 7 which are fixed to the bottom of the housing 1 in the front-rear direction so as to be movable in the front-rear direction. Reference numeral 8 denotes a knob for moving the slide box forward and backward provided with a screw shaft 9. The knob 8 rotates at the same position on the front surface of the bottom of the container casing 1, and the screw shaft 9 extends in the front-rear direction at the center of the front surface of the bottom plate 6a of the slide box 6. When the knob 8 is screwed in, the slide box 6 can be slid back and forth by a predetermined distance by being guided by the guide rod 7 by rotating the knob 8 with a finger.

Reference numeral 10 designates a front downward U-shaped support plate which can slide up and down in the slide box 6, and the downward side plates 10a on both the left and right sides of the support plate 10 are slidably contacted with the left and right inner walls of the slide box 6 to slide the slide box 6. A guide groove 11 is formed at the center of the left and right inner wall surfaces of the box 6 in the up-down direction, into which a projecting portion 10b projecting in the up-down direction is fitted at the center of the outer surface of the support plate side plate 10a.

Reference numeral 12 is a knob for raising and lowering a support plate provided on the container casing 1 provided with a screw shaft 13 which penetrates through a long groove 14 opened in the front-rear direction in the central portion of the top plate 1a of the container casing 1. The lower side of the shaft 13 is further inserted through the central portion of the strip plate 15 which is fixed in the front and rear direction to the central portion of the upper surface of the opening of the slide box 6, and the side surface downward protruding and fixed in the front and rear direction to the central portion of the support plate 10. The support plate 10 is suspended by being screwed into the U-shaped band plate-shaped engagement plate 16, and the support plate 10 can be raised and lowered through the engagement plate 16 by turning the knob 12, and as described above. When the screw shaft 13 of the knob 12 is fitted into the long groove 14 on the upper surface of the container case 1, the slide box 6 has its forward / backward moving distance restricted to the length of the long groove 14.

Reference numeral 17 designates two rotating disks of the same shape, which are arranged horizontally on the support plate 10 and are rotatable in the horizontal direction. The fixed supporting shafts 18, 18 of both disks 17, 17 are mounted on the upper casing. At a distance corresponding to the left and right spherical bearings 5 and 5 on the plate 10a, and at the backward movement end where the slide box 10 is restricted by the long groove 14, the slide box 10 is located slightly ahead of the spherical bearings 5 and 5 directly below. The foot rests 2 and 2 do not stand upright vertically from the beginning of rotation, but rather are in a state of sleeping.

Reference numeral 19 denotes a drive gear that simultaneously meshes with the outer peripheral surfaces of the left and right rotating discs 17, 17, and the gear 19 is driven by a reduction motor 20 mounted and fixed upward on the lower surface of the central portion of the support plate 10 to drive both discs. The 17, 17 are rotated in the same direction as each other.

The rotation speed of the motor 20 can be arbitrarily changed, and it is preferable that the motor 20 can rotate not only in the same direction but also in the opposite directions at a predetermined time (or a predetermined number of rotations). It is preferable to use a forward / reverse rotation motor that automatically reverses by a switch operation so that it rotates in the opposite direction every time the rotating disk 17 rotates about 3 to 5 times, and another same drive gear 19 is used. May be engaged with each other, and one of the disks 17, 17 may be engaged with each other and rotated in opposite directions.

Reference numeral 21 is a circular hole opened in the eccentric position of both the left and right rotating discs 17, 17, and the eccentric circular hole 21 is slightly larger than the outer diameter of the rod 3, and the lower part of the rod 3 is loosely inserted. As the disk 17 is horizontally rotated below the rods 3, a miso-slipping motion is performed around the rod spherical portion 4 which is pressed by the inner edge of the eccentric circular hole 21 and is supported by the upper spherical bearing 5, and the spherical portion 4 In the upper part, a downward conical locus motion is performed.

In the figure, numeral 22 is a power switch of the motor 20, and numeral 23 is a speed control knob for changing the rotation speed of the motor 20.

However, first, when using this health device, in addition to sitting on a chair, carrying out with the hips thrown on the floor (tatami mat), or lying upside down In some cases, the rotation direction of the footrest plate 2, that is, the angle of inclination of the footrest plate 2 with respect to the upper surface of the device casing 1 at the start of use also varies. For example, when sitting, it is necessary to make the angle of inclination of the footrest plate 2 loose and small, and when lying down, it is necessary to bring it closer to the standing direction, and when the hips are put on the floor, it is necessary to adjust to an intermediate angle. There is.

Therefore, the knob 8 on the front surface of the container casing 1 is rotationally adjusted according to these usage conditions to move the slide box 6 forward or backward in the container casing 1. When the slide box 6 is moved forward, the left and right rotating discs 17, 17 on the support plate 10 are also moved forward at the same time. Therefore, the rod 3 inserted downward in the disc 17 is supported by the spherical bearing 5 of the container top plate 1a. The angle in the vertical direction becomes smaller with the center of the rod spherical portion 4
The two footrests 2 and 2 go to sleep at the same time ((a) in FIG. 4).
(See (b)). When the slide box 6 is moved backward, the footrest plate 2 stands up, contrary to the above. Therefore,
By adjusting the knob 8, the most preferable front-back position of the slide box 6 is first selected.

In the embodiment, the front / rear position of the slide box 6 is finely adjusted by operating the knob 8. However, for example, the slide box 6 may be tension coiled so that the front / rear position can be set in three steps. The front end of the operating rod, whose base end is fixed to the bottom plate 6a of the slide box 6, is urged in the backward direction by a spring so that the front end of the operating rod is inserted into and protrudes from the front of the casing 1, and the middle portion of the operating rod is engaged with three front and rear positions. Forming a step,
It is also possible to employ a mechanism in which the operating rod is pulled forward to be engaged with an engaging portion formed on the front plate of the container casing 1 and the appropriate step portion to lock the operating rod.

Now, after the front and rear positions of the slide box 6 in the device casing 1 are determined as described above, the turning radius of the footrest plate 2, that is, the amount of rotation is set next. In this case, the lifting knob 12 on the upper surface of the device casing 1 is rotationally adjusted to vertically move the horizontal support plate 10 in the slide box 6, and the support plate 1 is moved.
The vertical insertion position of the rod 3 with respect to the eccentric circular hole 21 of the horizontal rotary disk 17 axially supported on 0 is selected.

As shown in FIGS. 2-3 and 4A, when the support plate 10 is at the lower end and the lower end of the rod 3 is engaged with the rotating disk 17, that is, the rotation of the rod 3. If the distance from the center spherical portion 4 to the rotary drive source that draws a circular locus is long, the radius of the circular locus drawn by the upper end of the rod 3 is small, and the radius of rotation of the upper end of the rod 3 increases as the drive source approaches ( See (a) of FIG. 4 and (a) of FIG. 5).

Therefore, when the sole is placed on the footrest plate 2 and the ankle is rotated, the greater the ankle is turned, the stronger the stimulus and the more intense the exercise and the blood flow effect is improved. In this case, the knob 12 is operated. The support plate 10 is pulled up (see FIGS. 5A to 5B), and in the case of a bedridden person or a person who wants to perform a light ankle rotation, the support plate 10 is lowered (FIG. 4A). )-(B)).

Further, the faster the rotation speed of the footrest plate 2 is, the stronger and more vigorous the motion is. Therefore, the rotation speed control knob 23 is used for adjustment.

In the embodiment diagram, both the left and right rotating discs 1
The drive gear 19 that meshes with the motors 7 and 17 is directly attached to the rotary shaft of the motor 20, but if the drive gear 19 is connected via a clutch plate, the rod 3 engages when the foot is placed on the footrest plate 2. The position of the eccentric circular hole 21 of the rotating disk 17 to be fitted can be easily brought to the foremost side by grasping the footrest plate 2 and the footrest becomes easy.

FIG. 6 shows another embodiment of the present invention. In the above-described embodiment, since the lower parts of the left and right rods 3 are simply inserted into the eccentric circular holes 21 of the rotary disk 17, there is some play, and when the disk 17 rotates, noise may be generated. Therefore, the solution to this is shown in FIG.
Mechanism. That is, in this case, the rod 3 is constituted by the inner and outer double tubes 3a and 3b which are slidable with each other, and a small spherical body 24 is formed at the lower end of the rod inner tube 3a, and the spherical body 24 is formed in each rotating disk. The rod inner tube 3a is supported by a spherical bearing 25 provided at an eccentric position 17 so that the rod inner tube 3a can swing freely around the lower end spherical bearing 25. A compression coil spring (not shown) may be inserted inside the rod outer tube 3b so as to urge the inner tube 3a to always press downward.

According to the configuration of FIG. 6, the rod inner tube 3b moves smoothly together with the disk 17 even if the disk 17 rotates, so that the footrest plate 2 installed on the head of the rod outer tube 3a also rotates. It is smooth, and when the disc 17 is moved up and down to change the turning radius of the footrest plate 2, the rods 3a and 3b of the inner and outer double pipes only expand and contract, so that the disc 17 moves up and down smoothly. Can be done.

FIG. 7 shows still another embodiment of the present invention. Instead of forcibly turning the footrest plate 2 by driving the motor as described above, the user turns the ankle by himself. It is a health device mainly for exercising and strengthening the ankle, and the rod 3 part below the intermediate spherical part 4 of the rod 3 supported by the spherical bearing 5 of the device casing top plate 1a is short. One end of a tension coil spring 26 is attached to the lower end of the rod 3 and the other end of the spring 26 is provided with a support plate 27 whose vertical position can be adjusted or the rotary disk 17 described above.
Is fixed to the head end surface of the fixed support shaft 18 of the
Alternatively, depending on the vertical position of the rotating disk 17, the spring 2
The strength can be adjusted by changing the tensile force of 6.
