DETAILED DESCRIPTION OF THE INVENTION The present invention performs acupressure pine surgery at a predetermined position on the body by rotating a wheel mounted eccentrically around the main shaft V, and also performs acupressure massage on both sides of the spine that is brought into contact with the wheel by moving the wheel. This relates to a pine surge device that performs so-called rolling pine surge, which performs pine surge along the spine, and its purpose is to reduce the number of switches and improve operability by providing multiple functions to the switch. is to provide.

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 of use. A frame 43 and a cover sheet 6 are arranged 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.

Rails 7 and 7 with openings facing each other are rotatably attached to each frame 4, 4, and a hooking protrusion 46 is attached to the upper surface of the rail 1.
It is installed protrudingly.

On the other hand, 8 rods 47 are attached to both ends of the cloth cover sheet 6, and 8 rods 47 are attached to both sides, and hook holes 48 are attached.
The cover sheet 6 is installed by passing the 8 rods 47 at both ends into the horizontal bar 44 in which the slit 49 is provided.
Then, the hooking protrusion 46 of the rail 7 is passed through the hooking hole 48, and the eight rods 47 on both sides are engaged with the hooking protrusion 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 configured.

Cylindrical bodies 16, 16 are freely rotatably attached to both ends of the main shaft 1, respectively, and guide rollers 17 attached to each of the cylindrical bodies 16 run within the rails 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.

The motor M in the motor block 9, which can freely rotate forward and backward, is connected to the main shaft 1 and the drive shaft 3 by a gear group and a planetary part in a gear box 10.

A pair of worm shafts 11 arranged in 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 boot 930 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 retainer 28 fixed to the worm shaft 11 should cause the balls 2
6 is prevented from orbiting and rotates on its axis.

This rotation is transmitted to the outer race 21 and passes through the outer race 27, pulley 32, belt 33, and pulley 34 to the worm shaft 1.
Rotate 3.

On the other hand, with the worm shaft 13 being braked, the inner race 2
5, the outer race 2 is inserted through the belt 33.
Since the ball 7 is locked, the ball 26 rotates and revolves, and rotates the worm shaft 11 via the retainer 28.

Of course, as shown in FIGS. 13 and 14, the planetary parts include a sun gear 25a1, a planetary gear 26a1, 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 simultaneously press-fitting 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 shown in the embodiment, but can be similarly configured with a tapered roller bearing using tapered rollers 26b as shown in FIG. 12, or an annular ball bearing. .

Particularly in the case of tapered roller bearings, a wedge effect can be obtained and a small preload force is required.

Note that FIGS. 11 and 12 are examples of planetary mechanisms using bearings, and the input and output do not correspond to the power transmission mechanism in the pine surge device of this embodiment.

If the worm shaft 11 is braked 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.
1. It is formed of SL2, and includes a yoke 54 attached to the gearbox 10, a core 55 that is integrated with the yoke 54 and faces the end surfaces of the worm shafts 11 and 13, an excitation coil 56, and a yoke 54 and core 55. The worm shaft 1
1 and 13, and a spring 57 that biases in the axial direction.
When a current is applied to the coil 56 to excite it, the worm shaft 11
The core 55 is attached to a movable block 58 fixed to one end of the ゜13.
The core 55 and the yoke 54 are attracted and driven against the spring 57 so that they are in contact with each other.

If the worm shaft 11°13 is 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.
1, and an outer ring 22 freely rotatable around the outer periphery of the shaft 1, and a steel ball 24 and a retainer 23 are arranged between the outer ring 22 and the eccentric shaft portion 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 gearbox 10 side, and a pair of reed switches LS1. This is to make LS2 sensitive.

Here, one reed switch SL1 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 designed to respond when the amount of protrusion of the wheel body 2 towards the cover sheet 6 side is large.

Additionally, a limit switch MS is attached to the gearbox 10.

This consists of two normally closed contacts S1. S2, when the actuator 39 is tilted to one side, one normally closed contact S1 opens, and when the actuator 39 is tilted to the other side, the other normally closed contact S2 is opened, and the mechanism section runs along the rail 7. when doing,
The mechanism is driven by a projection (not shown) attached to the end 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.

These 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.degree. 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 surge using the pine surge device constructed 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 parts 42, 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-mentioned rolling pine surge, if the rotational position of the wheel body 2 changes, the force exerted on the back by the wheel body 2 changes, so the strength can be adjusted.

Here, the side rollers 5 are used to adjust the strength and to make the acupressure treatment more effective.As shown in FIG. 8, when the amount of protrusion of the wheel body 2 is large, the side rollers My body floats away from Roller 5,
When the amount of protrusion of the wheel body 2 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, it is possible to treat a wider range of areas and to perform treatment with a soft feel. and always transform the body into two circular bodies 2,
Since the body is supported by the wheels 2, the body is always in a state of tension, which hinders integrity. However, when the amount of protrusion of the wheels 2 becomes small, the body is also supported by the side rollers 5, so the body is also supported by the side rollers 5. The tension will be relieved while you are there.

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 3, 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 a brake device that applies braking to each of the two outputs that can be taken out from this planetary mechanism are used. Configured solenoid S
L1. SL2 constitutes a clutch.

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

In other words, when performing a rolling pine surge, unless braking is applied to the main shaft 1, the strength cannot be adjusted using the eccentricity of the wheel 2, and when switching from rolling pine surge to acupressure pine surge, the drive shaft 3 must be braked. Unless the rotation is stopped by applying braking, the wheel body 2 cannot be stopped at the desired position.

In addition, with a normal clutch, there is a moment when the clutch separates from the power during switching, and at this moment the operation tends to become unstable due to force from the load side.

On the other hand, in the clutch using the planetary mechanism and electromagnetic brake shown in this embodiment, switching is done by applying braking to the previously connected output to connect the other output to power, so it is essentially The Naka@ part is a pair of solenoids SL1 which are the dragon bee brakes. It is only SL2 and does not require the operation of connecting or disengaging the clutch, so it can have a simple structure and is a part that is mechanically disconnected in a planetary mechanism that moves one time as a clutch when switching the connected output. This means that the 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 this figure shows the operation switch section, which includes a main switch SW1 and two operation switches SW2. SW3 connects the motor M and the solenoid SL, which is an electromagnetic brake, via the control circuit section 60.
1. SL2.

The main switch SW1 turns on and off the commercial power source E.

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 1 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.

When SW3 is in the "Shiatsu" position, if switch SW2 is set to "OFF", the shiatsu will be applied; if it is set to "UP" or "DOWN", the mechanism will be used to change the shiatsu position without performing shiatsu. moves.

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

If the switch SW3 is in the "weak" to "strong" position and the switch SW2 is "1 off", rolling pine surge is performed and the mechanism section is automatically reversed at the end of the rail 7.

Also, if switch SW2 is set to "up" or "down", the rolling pine surge is performed only in one direction determined by "up" or "down", and the rail 7
Stops at the terminal.

As is clear from the explanation up to this point, the switch SW3 is used to select between acupressure and rolling pine surge, and the switch SW2 moves the wheel 2 to a predetermined position during acupressure, and during rolling pine surge. functions as a selection switch for automatic or manual reversal.

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 is connected to a pair of switching elements T1. The clockwise or counterclockwise rotation is performed by conduction of either T2.

And both switching elements T1. T2 is a pair of relays R'
/,tR? '2 contact rY+ r It becomes conductive when rY2 is turned on.

These relays Ry1. Ry2 and a pair of solenoids SL, SL2, which are electromagnetic brakes, are each connected to a transistor Q1. Q2, Qs, Q4, and each transistor Q1-Q4 is operated by the output of the logic circuit section.

Now switch SW2 is in the off position and switch SW3
is in the acupressure position, and when the mechanism is not located at the end of the rail 7, that is, both normally closed contacts S1. When S2 are both in the on state, impark 11. The inputs of the flip-flop F formed by a pair of NOR gates NR+ and NR2 by I2 and OR gates 01 and 02 are both at L level, and both outputs are at H level and L level.

These two outputs and the output of switch SW3 are
-A1. AND gate A2 through NOR gate NR3, inverter ■3 and OR gate 03. It is input into A3.

At this time, the inputs of AND gate A2 are both at H level, turning on transistor Q1 and rotating motor M clockwise via relay Ry1 and switching element T1.

In addition, NOR gate NR4 becomes H due to the H output of inpark ■4, the L output of OR gate 05, and the L output of AND gate A4.
It outputs a level output, and when transistor Q3 is turned on, solenoid SL is excited.

This solenoid SL1 operates as an electromagnetic brake for the worm shaft 11, and for this purpose, the motor M
The output rotates the main shaft 1 through 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 inverter 15, transistor Q4 does not turn on when transistor Q3 is on.

This acupressure operation is performed when the mechanism is located at the end of the rail 7 and the normally closed contact S1. Even if either S2 is open, the output of flip-flop F does not change, or even if the output of flip-flop F changes, the outputs of AND gate A1 and OR gate 03 do not change, so exactly the same operation is performed.

When this switch SW3 is in the "shiatsu" position, if switch SW2 is set to "up", the H level output of AND gate A2 and the L level output of AND gate A3 remain unchanged, and the motor M moves to the right. Although it continues to rotate, the output of NOR gate NR4 goes to L level due to OR gate 05 and AND gate A4, transistor Q3 is turned off, transistor q is turned on by inverter 5, solenoid SL1 is restored, and solenoid SL2 is energized. 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 turned 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 the switch SW2 is set to "down", the output of the ant gate A2 becomes L1 and the output of the ant gate A3 becomes H, the motor M starts to rotate counterclockwise by the transistor Q2, the relay Ry2, and the switching element T2, and the output of the ant gate A2 becomes H. When the output becomes L, the solenoid SL2 is turned on, and the counterclockwise rotation output of the motor M is transmitted to the drive shaft 3 to move the mechanism toward the waist.

If switch SW2 is returned to 1 off, motor M will rotate clockwise.
The solenoid SL 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 LS1 is also set to "strong". When reed switch LS2 is off, motor M starts rotating in either direction depending on the state of flip-flop F, and since both inputs to Noah gate NR4 are at L level, solenoid SL1 is energized. The main shaft 1 is connected to a motor M to rotate the wheel body 2.

The permanent magnet 4 attached to the wheel body 2 during this rotation at most one rotation.
0 is reed switch LS1. Since LS2 is turned on, one input of NOR gate NR4 becomes H level, so this output becomes L 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 1", the rolling pine surge is performed with the reed switch LS1 reducing the amount of protrusion of the wheel 2, and when the switch SW3 is set to 1", the reed switch LS2 is activated to reduce the protrusion of the wheel 2. 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, both outputs of flip-flop F, whose outputs were HL, are inverted to LH, and the AND gate A2 output becomes L1, and the AND gate A3 output becomes H, and solenoid S
The motor M rotates from clockwise to counterclockwise while keeping L2 magnetized.

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

This movement closes the normally closed contact S1 and changes one input of the flip-flop F, but 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 SW2 is set to "Up" when switch SW3 is set to "1 Weak" or "Strong", motor M will rotate clockwise and solenoid SL2 will be energized, causing a rolling pine surge from the waist to the shoulder. Do the following.

When the upper limit is reached and the normally closed contact S1 opens, both outputs of the flip-flop F become L and the output of the OR gate 03 becomes L, so the AND gate A2. Both A3 outputs become L, and motor M stops.

If set to "down", a rolling pine surge will be performed from the shoulders to the waist, and when the lower limit is reached, the motor M will stop.

If the switch SW2 is set to the "1 off" position, automatic reversal is performed, and manual reversal can be performed within an arbitrary range by setting the "up" and "1 down" positions.

FIG. 17 shows another specific circuit diagram.

This applies to the solenoid SL1 for the circuit shown in Figure 16.
゜The logic circuit for controlling Sb2 has been changed, and the basic operation is the same as that of the circuit shown in Fig. 16, but the output of OR gate 03 for controlling motor M is a NAND gate. -1-ND5 and Noah gate N that outputs the control output of solenoid SL1 via Noah game 1-NR4
R, and OR gate 0 that outputs the control output of solenoid SL2.
Added to the input with □.

Also, the normally closed contact S1 of the limit switch MS. Both outputs of S2 are connected to the Nant gate ND1. ND2. ND3. N.D.
4. It is added to the OR gate 07 and the NOAH gate NR through the inverter 6 and the AND gate A.

A time constant circuit consisting of a resistor R and a capacitor C is inserted between the AND gate A and the OR gate 07.

This is the solenoid SL1 that stops the motor M. Braking is applied to the motor M by simultaneously exciting SL2.

Therefore, switch SW3 is 1 shiatsu", switch SW2 is
When is "off", motor M rotates clockwise, Noah gate NR
When the output 3 is at the H level, the solenoid SL1 is excited and the wheel 2 rotates at a fixed position to perform acupressure pine surge.

If the switch SW2 is set to "up" at this time, the motor M rotates clockwise, the solenoid SL2 is energized instead of the solenoid SL1, and the wheel body 2 starts moving.

When the upper limit is reached and the normally closed contact S1 is opened, the output of the OR gate 03 becomes L level, the outputs of AND gates A2 and A3 both become L level, and the motor M stops.

On the other hand, Nantes Gate ND1. ND3 and AND gate A5 cause the output of NOR gate NR5 to become H level, and solenoid SL1 is energized.

Both inputs of OR gate 0□ become L level and solenoid SL2 becomes de-energized. At this time, even if the AND gate A5 output changes from H level to L level, OR gate 0 is turned off by the time constant circuit. One input of □ remains at H level until it drops to the threshold voltage, so both solenoids SL1
．． Both SL2 are in an excited state.

For this purpose, the motor M is mechanically locked to prevent rotation due to inertia of the motor M.

The same is true when switch SW3 is set to "1 finger pressure" and switch SW2 is set to "down".

If switch SW3 is set to "1 Weak" or "Strong" and switch SW2 is set to "Off" position, rolling pine surge will be performed automatically, but if switch SW2 is set to "Up" or "Down", manual Even when the upper limit or lower limit is reached during the rolling pine surge with inversion by the AND gate A2. A3 output becomes L level, AND gate A2 output becomes L level, and NOR gate N
Since the R4 output goes to L level, the NR5 output goes to H level and solenoid SL1 is energized, and solenoid SL2 often remains energized through OR gate 07 due to the time constant circuit, and then becomes de-energized. Become.

Both Renoid SL. The simultaneous excitation of Sb2 applies braking to the inertia of the motor M, causing the motor M to stop instantaneously.

In other words, switch SW2 goes up by 1 or goes down by 1.
When set to , the output of AND gate A5 is high.
level, and capacitor C is charged, and when the mechanism reaches the upper and lower limits, both solenoids SL
1. An instantaneous stop is achieved by braking the motor M by simultaneous excitation of SL2.

This eliminates the disadvantage of using a planetary mechanism as a clutch and switching with an electromagnetic brake, that is, even after the motor M is turned off, the inertia of the motor M causes the connected output side to operate. Yes, even if motor M and both solenoids SL1. S
Even if L2 is de-energized, the previous operation will be reliably maintained the next time it is restored.

Thus, the present invention includes a switch for selecting either acupressure pine surge or rolling pine surge, and a switch for moving the wheel to a predetermined position during acupressure pine surge, and for automatic or manual reversal during rolling pine surge. Since the operation switch part is composed of another switch that selects whether to reverse or not, the other switch that is operated in response to the switch has multiple functions, reducing the number of switches and improving operability. This has the effect that it is possible to achieve the desired results.
