Effects of the Embodiments of the Invention Since the hydraulically driven chair-type health machine of the present invention is constructed as described above, it can operate as follows.

Before starting operation, the plug 102 of the electric cord 101 is securely inserted into an outlet (not shown).

As shown in FIG. 1, the user M sits on a chair and touches the heel of both feet to the foot fastener 30.

Next, the ankle is inserted between the heel support seat 312 and the instep presser seat 323 from both sides, the heel and the vicinity of the heel are brought into pressure contact with the heel support seat 312, and the instep presser seat 323 is placed on the instep part.

Next, while leaning your weight on the back seat 212, press the "inverted" switch on a hand-type remote controller (not shown) with your finger. Then, the health machine is energized and the motorized hydraulic pump 50 is activated.

When the hydraulic pump (indicated by P) is activated by starting the electric motor (indicated by N) of the electric motor-equipped hydraulic pump 50, pressurized oil is sucked from the inside of the oil tank 80, as shown in FIG. It is sucked into the hydraulic pump P through the suction port 52 of the hydraulic pump P through a pipe (oil tube 81), and enters the electromagnetic switching valve 7o through the discharge pipe (oil tube 71) from the discharge port 51 of the hydraulic pump.

The passage of the electromagnetic switching valve 70 is already set (switched) by an electric signal when the electric motor is started, and the pressure oil passes through this passage, is guided to the oil tube 414a, and is sent to the head side of the cylinder body 411. .

Then, the piston 413 is pushed toward the tail by the pressure oil, and the piston rod 412
P from the position shown in the figure! Move in the direction of the arrow. When the piston rod 412 moves in the direction of the arrow P1, the crank lever 42, to which the tip of the piston rod 412 is pivoted, rotates in the direction of the arrow h about the rotating shaft 60.

When the crank lever 42 rotates in the direction of the arrow h, the rotating shaft 60 to which the crank lever 42 is locked is rotated by the bearing 62,
Crank lever 4 while being supported by 63 (see Fig. 9)
Start rotating in the same direction as 2.

When the rotating shaft 60 starts rotating in the direction of arrow P2 in FIG. 9, the cam 64 welded to the rotating shaft 60 rotates in the same direction (in the direction of arrow P2) as shown in FIG. 6 or 11.

The cam 64 is as shown in FIG. 6 or 11.
4, the flange 642 of the cam 64 comes into contact with the roller 241b, and the roller 241b is pushed down by the flange 642 of the cam 64 having a large concentric diameter.

Then, as shown in FIGS. 6 and 12, the roller link 241 and the main link 242 are integrated (
The operating link rotates about the pin shaft 241a as a fulcrum, and the main link 24
The front side of 2 rises.

Following the rotation of the operating link, the slave link 243 also rotates the pin shaft 2.
It rotates about 31a as a fulcrum, and the rear side of the slave link 243 rises.

Then, the leg rod 23 is pushed out by the aforementioned operating link-follower link 243 through the link attachment piece 231, rotates about the fixed shaft 223 of the seat rod 22 as a fulcrum, and its lower part rises. That is, the interlocking body starts operating.

At the same time as the rotating shaft 60 starts rotating and the interlocking body starts operating, the back seat 212 fixed to the connecting plate 211 welded to the rotating shaft 60 rotates around the rotating shaft 60, as shown in FIG. It spins around and falls backwards.

Pressure oil continues to be supplied, the interlocking body continues to operate, and the leg lever 23
When the front part of the seat 212 rises and eventually reaches a state where it is almost flush with the seat 225, the interlocking body stops operating, and the back seat 212 is also turned upside down, reaching a state slightly lower than the horizontal state of the seat 225.

On the other hand, when the rotation of the rotating shaft 60 starts, FIGS.
As shown in Figure 0, when the main clutch piece 65 attached to the rotating shaft 60 also rotates, and the rotation angle is 80 degrees, the interlocking body, the seat 225, and the back seat 212 are slightly different, but they are almost horizontal. Line up in the state and become the state of the flat table. (Hereinafter, this flat table will be referred to as a rotary table.) When the main clutch piece 65 rotates by 95 degrees, the main clutch teeth 651 of the main clutch piece 65 come into contact with the slave clutch teeth 661 of the slave clutch piece 66, and push the slave clutch teeth 661. Therefore, the slave clutch piece 66 also starts rotating together with the rotating shaft 60.

When the slave clutch piece 66 starts rotating, the slave clutch piece 6
6 outer peripheral edge (link 221 of seat lever 22 with the rear end welded)
(that is, the seat 225) rotates around the rotating shaft 60. At the same time, the leg rod 23 and the back seat 212 also rotate together with the seat 225 as a two-turn table.

On the other hand, as shown in FIG. 20, the piston 4 is
When 13 is pushed from the cranial side to the caudal side, the piston 4
13 and the tail end of the cylinder body 411 is pushed by the piston 413 and extruded from inside the cylinder body 411 through the oil hole 415. The extruded oil is sent to the electromagnetic switching valve 70 by the oil tube 415a, passes through a path different from the one described above, and is sent into the tank of the oil tank 80 by the oil tube 72.

Further, when the operation of the hydraulic drive device 40 is continued, the rotary table moves from the horizontal position to an inclined position with the head lower than the feet as shown in FIG. '' is released to cut off the power, the electric motor M of the motor-equipped hydraulic pump 50 is turned off, and the rotation of the rotary table is stopped. At this time, the crank lever 42 and the piston 413 are in the position indicated by the dotted line in FIG. 20.

Also, the contact state of both clutch teeth at this time is shown in Figure 10 (
As shown in B).

Note that if it is desired to tilt the rotary table and stop it at an arbitrary angle position, this can be done by manual operation of the remote controller.

The user M's body tends to slide backwards on the rotating table as the rotating table rotates and tilts, but this can be prevented by using the foot fasteners 30.

In other words, when rotating the rotary table, the ankle and calcaneus are
12 and the instep presser seat 323, the heel and the vicinity of the heel are pressed against the seat 312, and the instep presser seat 323 is placed on the instep part.

As the rotation of the rotary table progresses, the upper presser seat 323 moves to the pin shaft 324.
Rotate around the axis and press the instep part.

This calcaneus is clamped and pressed by both the seat 312 and the instep presser seat 323, so that the ankle is constrained and the rotating table is rotated.

Even if the tilt progresses, the user M's body does not move on the rotating table.

Note that the calcaneus seat 312 and the upper presser seat 323 are both made of flexible materials as described above, so the user M can rotate and tilt the rotary table and wait for the tilting time to pass. However, I don't feel any pain at all.

After a certain period of time (about 15 to 30 minutes is most effective) while the device remains tilted, the user λdong presses the "stand up" switch on the remote controller with his finger.

Then, the health machine is energized again, and the electric motor M of the electric motor-equipped hydraulic pump 50 is started. At the same time, relay 10
The passage of the electromagnetic switching valve 70 is switched by an electric signal via 0.

When the electric motor M is started and the hydraulic pump P starts operating, pressure oil is supplied from the inside of the oil tank 80 to the suction port 52 of the hydraulic pump P through the suction pipe (oil tube 81), as shown in FIG. 1 into the hydraulic pump P,
A discharge pipe (oil tube 7) is connected from the discharge port 51 of the hydraulic pump.
1) into the electromagnetic switching valve 70.

In the electromagnetic switching valve 70, the pressure oil passes through a passage already switched by an electric signal, is guided to an oil tube 415a, and is sent to the tail portion of the cylinder body 411.

When pressure oil is fed into the tail of the cylinder body 411, the piston 413 is pushed from the dotted line position in FIG. 20 toward the solid line position by the pressure oil, and the piston rod 412
moves in the direction of the Qs arrow.

When the piston rod 412 moves in the direction of the arrow, the crank lever 42 rotates about the rotating shaft 60 in the direction of the middle arrow.

When the crank lever 42 rotates in the direction of the arrow, the rotating shaft 60 starts rotating in the same direction as the crank lever 42 while being supported by bearings 62 and 63, and the cam 64 welded to the rotating shaft 60 rotates in the direction of the middle arrow. do. (See FIG. 6) Then, as shown in FIG. 12, due to the rotation of the cam 64, after a while, the boss portion 641 of the cam 64 and the curved portion between the valleys of the collar portion 642 gradually come into contact with each other. The roller 241b rises.

As the roller 241b rises, the roller link 241
The operating link, which is integrated with the main link 242, rotates about the pin shaft 241a as a fulcrum, and the front side of the main link 242 descends.

Following the rotation of the operating link, the slave link 243 also rotates the pin shaft 2.
It rotates about 31a as a fulcrum, and the rear side of the slave link 243 descends. Then, the leg rod 23 is pulled back by the operating link-follower link 243, the seat rod 23 rotates about the fixed shaft 223, and the lower part of the seat rod 23 is lowered. That is, the interlocking body starts operating in the opposite direction to that described above.

At the same time that the rotating shaft 60 starts rotating in the Q2 direction and the interlocking body starts operating, the connecting plate 211 welded to the rotating shaft 60
The seat back 212 fixed to the seat rotates around the rotation axis 60, rises from a rearwardly inclined position, and gradually moves to a horizontal position.

When the rotating shaft 60 starts rotating in the middle direction, first, only the main clutch piece 65 rotates together with the rotating shaft 60, and the rotation angle is 95.
The main clutch teeth 651 of the latch piece 65 rotate each time.
comes into contact with the slave clutch teeth 661 of the slave clutch piece 66, pushes the slave clutch teeth 661, and the slave clutch piece 66 also touches the rotation shaft 6.
0 and rotates in the Q2 direction.

At the same time, the leg rods 23 and the back seat 212 also rotate together with the seat 225 as a rotating base. On the other hand, as shown in Figure 20,
When the piston 413 is pushed from the caudal side to the cranial side by the pressure oil, the piston 413 (points in the direction indicated by the dotted line)
The oil existing between the cylinder body 411 and the head side of the cylinder body 411 is pushed by the piston 413 and extruded from the cylinder body 411 through the oil hole 414.

The extruded oil is sent to the electromagnetic switching valve 70 by the oil tube 414a, passes through a different path than the above-mentioned passage switched by an electric signal, and is sent into the tank of the oil tank 80 by the oil tube 72.

Furthermore, when the operation of the hydraulic drive device 40 is continued, the rotary table returns from the horizontal position to the state at the start of startup shown in FIG. 1 to form a chair.

At this time, as shown in FIG. 6, when the rotary table returns to the state at the start of startup and forms the chair, in order to maintain the same state, two parts of the interlocking body are welded to the rear part of the slave link 243. One side of the equilateral triangular urine seat 244 presses against the upper side of the main link 242 to prevent the interlocking body from swirling.

When the rotary table returns to the state at the start of startup, the user M releases the finger that pressed the "stand" switch on the controller to turn off the power, turns off the electric motor M of the motor-equipped hydraulic pump 50, and resumes hydraulic drive. Deactivate the device.

At the same time, the passage of the electromagnetic switching valve 70 is switched by an electric signal via the relay 100.

User M removes his ankles from the foot fasteners 30 and gets off the chair.
