Description

[Detailed description of the invention] This invention uses the pressing force of a ring mounted eccentrically on the main shaft to perform acupressure pine surgery on a fixed position on the body, and by moving the ring, both sides of the spine are brought into contact with the ring. This relates to a pine surge device that performs so-called rolling pine surgery, which performs pine surgery along the spine.The purpose of this device is to automatically stop when the wheel moves along the spine and reaches the upper or lower end to perform acupressure pine surgery. We offer pine surge equipment to do this.

The present invention will be described in detail below based on illustrated embodiments.

Fig. 1 shows the external appearance of one embodiment, and Fig. 2 shows the state in use. A side frame 43 and a cover sheet 6 are disposed on the upper surface, and as shown in FIG.
The upper part is a cushion part 42
The pair of legs 41 are bolted together, and the cover sheet 6 and side frame 43 are attached.

Each frame 4 has a rail 7 with openings facing each other.
7 is fixed to the rail 7, and a hook protrusion 46 is provided on the upper surface of the rail 7.

On the other hand, core ropes 7 are attached to both ends of the cloth cover sheet 6,
In addition, the core rope 7 is attached to both sides, and hook holes 48 are provided, and the cover sheet 6 can be attached through the slit 49.
The core rods 47 at both ends are passed through the horizontal branches 44 provided with the rails, and the hooking protrusions 46 of the rail 7 are passed through the hooking holes 48, and the cores n47 on both sides are engaged with the hooking protrusions 46.

The side frame 43 is made by covering the outer surface of a core material 50 with foamed urethane resin 51 and cloth 52, and is fixed to the frame 4 with screws.

On a pair of rails 7.7 to which racks 8 are fixed in the longitudinal direction, a mechanism section including wheels 2, 2 for performing pine surge is installed.

This mechanism unit has a motor M and is self-propelled along a rail 7, and has a motor block 9 at one end of the main shaft 1 on which the wheels 2, 2 are attached at the center, and a gear box 10 at the other end. It is arranged and arranged.

Cylindrical bodies 16 and 16 are attached to both ends of the main shaft 1 so as to freely rotate, and guide rollers 17 are attached to each of the cylindrical bodies 16.
runs on rail 7.

Furthermore, as shown in FIGS. 6 and 7, the gearbox 10 and motor block 9 are equipped with guide rollers 17 that run within the rail 7 via a shaft 53, and these four guide rollers 17 control the mechanism. It is constructed between the rails 7 and 7.

As shown in FIG. 5, the main shaft 1 is hollow and has a drive shaft 3 mounted therein, and the above-mentioned cylindrical body 16 is fixed to both ends of the drive shaft 3.

Each cylindrical body 16 is formed with a pinion 15 that meshes with a rack 8 attached to the rail 7, so that when the drive shaft 3 is rotationally driven, the mechanism section runs along the rail 7.

In this embodiment, the motor M in the motor block 9, which can freely rotate forward and backward, and the main shaft 1 and the drive shaft 3 are connected by a gear group and a planetary part in the gear box 10.
An output switching mechanism together with a brake device formed by solenoids SLI and SL2, which will be described later.

It constitutes A.

A pair of worm shafts 11 arranged within the gearbox 10.
Among the worm shafts 13, one worm shaft 11 meshes with a worm wheel 12 fixed to one cylindrical body 16, and the other worm shaft 13 meshes with a worm wheel 14 fixed to a shaft 18, as shown in FIG. Fit.

An elliptical gear 19 is also fixed to the shaft 18, and this elliptical gear 19 meshes with an elliptical gear 20 fixed to the main shaft 1.

These worm shafts 11 and 13 are connected via a planetary part.

In the embodiment shown in FIG. 6, this planetary part is constituted by a ball bearing; the sun gear is an inner race 25, the planet gear is a ball 26, the internal gear is an outer race 27, and the planet carrier is a retainer 28. form and attach the inner race 25 to the worm shaft 1.
It is fixed to the outer periphery of a collar 29 which is freely rotatably attached to the collar 1.

This collar 29 is provided with a pulley 30 connected to the output shaft of the motor M by a belt 31.

The worm shaft 11 is connected to the planetary part by connecting the retainer 28 that restricts the movement of the balls 26 to the worm shaft 11, and the worm shaft 13 is connected to the worm shaft 13 by a pulley 34 fixed to the worm shaft 13 and a belt 33. This is done by fixing the pulley 32 connected to the outer race 27.

Now, if the collar 29 and the inner race 25 are rotated by the motor M with braking applied to the worm shaft 11, the ball 2 is rotated by the retainer 28 fixed to the worm shaft 11.
6 is prevented from orbiting and rotates on its axis.

This rotation is transmitted to the outer race 27 and passes through the outer race 27, pulley 32, belt 33, and pulley 34 to the worm shaft 1.
On the other hand, if the inner race 25 is rotated with the worm shaft 13 being braked, the outer race 27 is locked through the belt 33, so the ball 26 is rotated.
rotates and revolves to rotate the worm shaft 11 via the retainer 28.

Of course, as shown in FIGS. 13 and 14, the planetary parts include a sun gear 25a, a planetary gear 26a, and an internal gear 27a.
Although a general planetary gear mechanism including a planet carrier 28a and a planetary carrier 28a may be used, the use of a bearing is superior in that it is quieter, has a simpler structure, and can be made at a lower cost.

However, when using bearings, power transmission is limited to the inner race 25.
Since friction is conducted between the ball 26 and the ball 26, and between the ball 26 and the outer race 27, it is necessary to apply a preload between them.

Normally, this is done by press-fitting the shaft into the inner race 25 and the outer race 27 into the housing, but this does not make it easy to control the dimensions, so in this embodiment, the outer race 27 is pressed into the housing. The fixed pulley 32 is biased in the thrust direction by a coiled preload spring 35, thereby applying a thrust preload force between the inner race 25 and the outer race 27.

Therefore, a predetermined preload can be easily applied by adjusting the spring force of the preload spring 35 without requiring high dimensional accuracy or press-fitting accuracy of the inner race 25 or outer race 27.

In addition, in the figure, 36 is a spring bearing, and 37 is a bearing for the spring bearing.

Instead of both, a thrust bearing 38 may be used to apply the spring pressure of the preload spring 35 to the inner race 25 via the thrust bearing 38, as shown in FIGS. 11 and 12.

Of course, other types of bearings may be used.

Furthermore, the bearing used as the planetary part does not have to be the deep groove ball bearing mentioned in the embodiment, but may be a tapered roller bearing using tapered rollers 26b as shown in FIG. 12, or an angular bearing.
A similar configuration can be made using a type ball bearing.

In particular, tapered roller bearings have the advantage of achieving a wedge effect and requiring less preload force.

Note that FIGS. 11 and 12 are examples of a planetary mechanism using bearings, and the human output does not correspond to the power transmission mechanism in the pine surger of this embodiment.

If the worm shaft 11 is controlled as described above, the worm shaft 1
3, and if the worm shaft 13 is braked, the worm shaft 1
This braking is performed by a brake device provided at one end of each worm shaft 11, 13.

Each brake device has a solenoid SL as shown in Figure 10.
I, SL2, and includes a yaw 54 attached to the gearbox 10, a core 55 that is integrated with the yoke 54 and faces the end face of the worm shaft 11° 13, an excitation coil 56, and the yoke 54. and the core 55 on the worm shaft 11. When a current is applied to the coil 56 and the coil 56 is energized, the core 55 and the worm shaft 11. Yoke 54 is connected to spring 57
is driven by suction against the

If the worm shaft 11.13 was rotating, the core 55
The rotation is stopped when the movable block 58 is joined to the movable block 58.

As is clear from FIG. 5, the wheel body 2 attached to the main shaft 1 includes an eccentric shaft portion 21 fixed to the main shaft 1, and an eccentric shaft portion 2.
A steel ball 24 and a retainer 23 are arranged between the outer ring 22 and the eccentric shaft part 21.

The pair of wheels 2, 2 attached to the main shaft 1 at a predetermined interval rotate together with the main shaft 1 in a plane perpendicular to the axial direction of the main shaft 1, but both wheels 2, 2 rotate in the same direction. Therefore, as the main shaft 1 rotates, the amount of protrusion of the wheel body 2 toward the cover sheet 6 side changes.

The state changes from the state of the minimum protrusion amount shown by the solid line in FIG. 5 to the state of the maximum protrusion amount shown by the imaginary line in the figure.

A permanent magnet 40 is attached to the side surface of the eccentric shaft portion 21 of the wheel body 2 on the side of the gearbox 10, so that a pair of reed switches LSI and LS2 arranged on the side surface of the gearbox 10 are sensitive to the permanent magnet 40.

Here, one reed switch LS1 is sensitive to the permanent magnet 40 when the amount of protrusion of the wheel body 2 toward the cover sheet 6 side is small, and the other reed switch LS2 (not shown in FIG. 5) is connected to the wheel body 2. It is designed to respond when the amount of protrusion toward the cover sheet 6 side is large.

Furthermore, in this embodiment, a limit switch MS is used as a detection means for detecting when the drive shaft has moved and reached both ends, and this limit switch MS is connected to the gear box 1.
It is attached to 0.

This has two normally closed contacts Sl and S2, and when the actuator 39 is tilted to one side, one normally closed contact S1
When the two normally closed contacts S2 open and are pushed to the other side, the other normally closed contact S2 opens, and when the mechanism section runs along the rail 7,
When the mechanism reaches the end of the rail 7, the actuator 3
9 is driven by protrusions (not shown) attached to both ends of the rail 7'.

Side rollers 5 are provided on the upper surface of the gear box 10 and the upper surface of the motor block 9 by shafts 59 disposed parallel to the main shaft 1, respectively.

The side rollers 5, which are freely rotatable, have a total of 4 rollers, two on the motor block 9 and two on the gear box 10.
These are located on both sides of the pair of wheels 2, 2, and are arranged at a slightly lower height than the wheels 2 when the amount of protrusion toward the cover sheet 6 is small.

To perform pine surgery using the pine surgery device configured as described above, as shown in FIG. 2, the upper body is laid down on the cover sheet 6, and the head and buttocks are placed on the cushion portions 42 and 42 at both ends.

If only the drive shaft 3 is rotated without rotating the main shaft 1, the mechanical part runs along the frame 4 and the rail 7 below the cover sheet 6 due to the engagement between the pinions 15 at both ends of the drive shaft 3 and the rack 8. do.

At this time, the outer ring 22 of the ring body 2 presses both sides of the spine along the spine via the cover sheet 6 while rotating freely, and a rolling pine surge is performed.

If only the main shaft 1 is rotated without rotating the drive shaft 3, the wheel body 2 rotates at a fixed location.

Since the wheel body 2 is eccentric with respect to the main shaft 1, the amount of protrusion toward the cover sheet 6 changes as it rotates.

That is, the states shown in FIGS. 8 and 9 occur alternately.

Therefore, acupressure action can be obtained using the wheel body 2.

Further, as is clear from FIGS. 8 and 9, even during the above-described rolling pine surge, if the rotational position of the wheel body 2 changes, the pressing force applied to the back by the wheel body 2 changes, so the strength can be adjusted.

At this point, the side roller 5 adjusts this strength.
This makes it possible to perform acupressure treatment more effectively, and as shown in FIG. When the amount of protrusion is small, the side rollers 5 come into contact with the body as shown in FIG.

Since this side roller 5 moves together with the wheel body 2, when performing rolling pine surge, the wheel body 2
In addition, by moving the side rollers 5 in contact with the body, a wider range of areas can be treated, and the treatment can be performed with a soft feel.

Also, when performing acupressure pine surgery, if only the circular body 2 is used, the body will always be supported by the two circular bodies 2, 2, and the body will always be in a state of tension, which will hinder the treatment.
When the amount of protrusion becomes small, the body is also supported by the side rollers 5, so the tension is relieved while the body is supported by the side rollers 5 as well.

In other words, a state of tension and a state of relaxed tension are repeated, resulting in more effective treatment.

As is clear from the above explanation, this pine surge device is
By switching the power transmission of the motor M between the main shaft 1 and the drive shaft 3Z, rolling pine surgery to stretch the back and acupressure pine surgery at a fixed position are performed.

Therefore, a clutch is required for switching, but as mentioned above, in this embodiment, a planetary mechanism and an electromagnetic brake device that applies braking to each of the two outputs that can be taken out from this planetary mechanism are used. A clutch is composed of solenoids SLI and SL2.

By the way, when switching and extracting two outputs from a single power source via a clutch, when switching from one output to the other, braking must be applied from the load side to the previously connected output. Problems arise with this pine surge device.

In other words, unless you apply braking to the main shaft 1 before performing rolling pine surge, you will not be able to adjust the strength or weakness using the eccentricity of the wheel 2, and when switching from rolling pine surge to shiatsu pine surge, the drive Unless the rotation of the shaft is stopped by applying braking, the wheel body 2 cannot be stopped at the desired position.

In addition, with normal clutches, there is a moment when the clutch is disconnected from the power, and at that moment the operation tends to become unstable due to force from the load side.

On the other hand, in the case of the clutch using the planetary mechanism and electromagnetic brake shown in this embodiment, switching is done by applying braking to the previously connected output and connecting the other output to power. The only moving parts are a pair of solenoids SLI and SL2, which are electromagnetic brakes, and there is no need to engage or disengage the clutch, which allows for a simple structure and the ability to switch the connected output. A planetary mechanism that sometimes functions as a clutch has no mechanically disconnected parts, and its operation is stable even if force is applied from the load side during switching.

The operation will be explained in more detail below based on the circuit diagram.

FIG. 15a shows a schematic circuit configuration, and the same figure shows the operating section, showing main switches SW, l and two operating switches SW2. SW, 3 connects the motor M and the solenoid S L, which is an electromagnetic brake, via the control circuit section 60.
1. SL2.

The main switch S W t is used to turn on/off the commercial power supply E.
Perform off.

Switch SW2. Both SW3 are 3-position switching type and can be switched independently, and as shown in the figure, the middle point of switch SW2 is "off", one is "up", and the other is "down". ”,
The switch SW3 has one end set to "shiatsu", the middle point set to "weak", and the other end set to "strong".

Here, "shiatsu" refers to acupressure pine surge, "weak" and "strong"
will perform a rolling pine surge.

And when switch SW3 is in the "Shiatsu" position,
If switch SW2 is "off", shiatsu is "up"
If set to "down", the mechanism moves to change the position of acupressure without applying acupressure.

In addition, "going up" means that the mechanism moves toward the head.
"Down" indicates moving toward the waist.

If the switch SW2 is "off" while the switch SW3 is "weak" to "strong", rolling pine surge is performed and the mechanism section is automatically reversed at the end of the rail 7.

Also, when switch SW2 is set to "up" or "down", rolling pine surge is performed only in one direction determined by "up" or "down", stops at the end of rail 7, and automatically performs shiatsu massage. Switch to Pine Surge.

As is clear from the explanation so far, the switch SW3 is used to select between acupressure and rolling pine surge, and the switch SW2 moves the ring body 2 to a predetermined position during acupressure, and during rolling pine surge. oh·
The terminal functions as a selection switch for automatic reversal or switching to acupressure pine surge.

In other words, the switch SW2 is provided with multiple functions to reduce the number of switches and improve operability.

FIG. 16 shows an example of a specific circuit, in which the motor M rotates clockwise or counterclockwise by conducting one of the pair of switching elements TI and T2.

Both switching elements TI and T2 are connected to contacts ry1. of a pair of relays Ry+ and Ry2. It becomes conductive when ry2 is turned on.

These relays Ry1. Ry2 and a pair of solenoids SLI and SL2, which are electromagnetic brakes, are each connected to a transistor Q3. Q2. Q3. Q4, and each transistor Ql-Q4 operates on the output of control circuit C.

That is, the above-mentioned switching elements TI, T2 and relays Ry1. Ry2 and relay Ry1. Transistor Q1 that drives Ry2. Q2 and solenoid SLt, transistor Q3 that drives SL2. Motor drive circuit B with Q4
is at the bottom of the tank.

Next, the control circuit C will be explained.

Now switch SW2 is in the off position and switch SW3
is in the finger pressure position, and when the mechanism is not located at the end of the rail 7, that is, when both normally closed contacts Sl and S2 of the limit switch MS are in the ON state, the inverters II and I2 and the OR gate 01 .

These two outputs and the output of switch SW3 are connected to AND gate A
1. Human-powered by Noah Gate NR3 and Or Gate 03.

At this time, both of the input power of the NOR gate NR3 are at the L level, and the output of the NOR gate NR3 is at the H level, so the transistor Q1 is turned on and the motor M is rotated clockwise via the relay Ry1 and the switching element T1.

Also, the H output of the OR gate 03 is the L output of the switch SW3.
Along with the output, it is manually input to AND gate A2.

On the other hand, Nantes Gate N1. The L output of another Nant gate N3 connected to N2 and the H output of inverter 4 are input to AND gate A3, and the L output of this AND gate A3 is connected to OR gate 04 and NOR gate together with the L output of AND gate A2. Each of them is manually operated in parallel with NR4.

Therefore, the NOR gate NR4 outputs an H level output, and when the transistor Q3 is turned on, the solenoid SL is excited.

This solenoid S Ll operates as an electromagnetic brake for the worm shaft 11 , and for this purpose, the output of the motor M rotates the main shaft 1 via the planetary mechanism and the worm shaft 13 .

Therefore, the wheel body 2 rotates in a fixed position and performs acupressure operation.

Due to the presence of OR gate 04, transistor Q4 does not turn on when transistor Q3 is on.

In this acupressure operation, even if the mechanism is located at the end of the rail 7 and either normally closed contact Sl or S2 is open, the LL large input of flip-flop F will only change from LH human power to HL human power; The output either remains as it is or is reversed to LH and is manually input to AND gate A1 to OR gate 03, so the L output of AND gate A1 to H output of OR gate remain unchanged.Shiatsu operation by clockwise rotation of the remoter changes. do not have.

When this switch SW3 is in the "shiatsu" position, if the switch SW2 is set to "up", the motor M will rotate clockwise without changing the H level output of the Nantes gate NR3 and the L level output of the inverter L. However, as the output of AND gate A3 becomes H level, the output of NOR gate NR4 becomes L level, transistor Q3 is turned off, and OR gate 04 becomes H level, transistor Q4 is turned on, and solenoid S
L returns, solenoid SL2 is energized, and braking is applied to the worm shaft 13.

Therefore, the clockwise rotation output of the motor M is transmitted to the drive shaft 3 through the worm shaft 11, and the mechanism moves toward the shoulder due to the engagement between the pinion 15 and the rack 8.

If the switch SW2 is returned to "off" when the wheel body 2 has moved to the desired position, the rotation of the wheel body 2 will begin at that position and acupressure action will be performed.

When switch SW2 is set to "down", NOR gate NR3 output becomes L and inverter ■3 output becomes H, transistor Q2, relay Ry2, and switching element T2
The motor M starts to rotate counterclockwise, and the Noah gate NR
4 output becomes L and OR gate 04 becomes H level, transistor Q4 is turned on, and the counterclockwise rotation output of motor M is transmitted to drive shaft 3 to move the mechanism toward the waist.

If switch SW2 is returned to "off", motor M will rotate clockwise.
Solenoid SL1 is energized and starts the acupressure operation again.

For rolling pine surge, set switch SW3 to "weak" or "
This is done by setting it to "Strong".

If switch SW2 is in the "off" position, automatic reversing operation can be obtained, but when switch SW3 is set to "weak" at the beginning of this operation, reed switch LS t is also set to "strong". If reed switch L S 2 is off when set to
starts rotating in either direction depending on the state of flip-flop F, and OR gate 04 and NOAH gate NR4
Since both of their powers are L level, Noah Gate NR
4 becomes H level, the solenoid S Lt is excited, the main shaft 1 is connected to the motor M, and the wheel body 2 is rotated.

The permanent magnet 4 attached to the wheel body 2 during this rotation at most one rotation.
0 is the reed switch L S 1. Since L S 2 is turned on, the human power of one of OR gate 04 and NOR gate NR4 becomes H level, so the output of NOR gate NR4 becomes L level, and at the same time, the output of OR gate 04 becomes H level, and solenoid SL2 is excited.

The rotation output of the motor M is switched to the drive shaft 3.

In this way, when the switch SW3 is set to "weak", the reed switch LSI reduces the amount of protrusion of the wheel body 2 and rolling pine surge is performed, and when the switch SW3 is set to "strong", the reed switch LS2 causes the wheel body to perform a rolling pine surge. Rolling pine surge is performed in a state where the amount of protrusion 2 is large.

Then, when the motor M is rotating clockwise and the mechanical part is moving toward the shoulder, when this movement reaches the end of the rail 7, the normally closed contact S1 opens.

For this reason, the output of flip-flop F, whose output was HL until then, is inverted to LH, the NOR gate N'R3 output becomes L, the inverter ■3 output becomes H, and solenoid S
The motor M rotates from clockwise to counterclockwise with L2 being energized.

The mechanism automatically reverses itself and begins to move down towards the waist.

This movement closes the normally-closed contact S1 and changes the human power of both flip-flops F to L level, but due to the nature of this flip-flop F, the output does not change.

Conversely, if the normally closed contact S2 is opened, the motor M changes from left rotation to right rotation and continues the rolling pine surge.

If switch SW3 is set to "weak" or "strong" and switch SW2 is set to "up", the terminal will automatically switch from rolling pine surge to acupressure pine surge, but if switch SW2 is set to Similar to the "off" state, at the beginning of this operation the switch S
If reed switch LS1 is off when W3 is set to "weak," and reed switch LS2 is off when W3 is set to "strong," motor M will move in either direction depending on the state of flip-flop F. The rotation starts, and since both the human power of OR gate 04 and NOAR GAME) NR4 are at L level, the output of NOAH gate NR4 becomes H level, solenoid S L ] is energized, main shaft 1 is connected to motor M, and wheel body 2 Rotate.

The permanent magnet 4 attached to the wheel body 2 during this rotation at most one rotation.
0 turns on reed switches L S + and L S 2, so one input of OR gate 04 and NOR gate NR4 becomes H level, so the output of NOR gate NR4 becomes L level and at the same time the output of OR gate 04 becomes H level.
level, and solenoid SL2 is energized.

The rotation output of the motor M is switched to the drive shaft 3.

Thus, when the drive shaft 3 moves towards the shoulder and reaches the terminal, the normally closed contact S1 opens.

For this reason, the output of flip-flop F, whose output was HL, becomes LL, but the output of NOR gate NR3 becomes H.
Output, L output of inverter ■3 remains unchanged, motor M
remains rotated to the right.

However, the outputs of AND gates A2 and A3 are inverted to L level, so that solenoid SL2 is de-energized and solenoid SL is energized.

That is, the terminal automatically switches from rolling pine surge to acupressure pine surge.

Also, when the drive shaft moves toward the waist and the mechanical section reaches the terminal, it automatically shifts to acupressure pine surge in the same way.

Furthermore, as mentioned above, the same output of flip-flop F is LL
In this case, the force of both people on flip-flop F is H
H, but in this case, if both forces of the flip-flop F are set to LL at the same time, the operation of the flip-flop F becomes uncertain; however, in this embodiment, the contact S1 or S2
If switch SW2 is operated even though the switch S
After operating W2, the drive shaft is shifted and then contact S1 or S2 is turned on. In other words, contact SIT 82 and switch SW2 are not input at the same time due to mechanical operation. Both forces do not become LL at the same time, and therefore, the operation of the flip-flop F does not become uncertain.

As described above, in this invention, acupressure pine surgery is performed by rotating a pair of eccentrically attached wheels, and at the same time, when the wheels move along the spine and reach the upper or lower end, the Since the rolling pine surge is switched to the shiatsu pine surge, the pine surge device does not perform any operation even when the power is on, and the effect is that it always displays that the pine surge device is operating. Moreover, when moving toward the shoulder and stopping at the upper limit to perform acupressure pine surgery, the upper limit corresponds to the neck area, which is the affected area where pine surgery is often needed. It has a good effect.
