Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a pine surgery machine, particularly a pine surgery machine that is equipped with a rotating treatment member that is eccentrically attached to a rotationally driven main shaft and a moving mechanism that makes the position of the rotational treatment member variable. This is about a pine surge machine.

[Background Art] In the above-mentioned pine surge machine, the pine surge mechanism is built into the backrest or bed of the chair, and the change in the amount of protrusion in one direction due to the rotation of the eccentric rotating treatment member changes the pressure applied to the human body. This system performs pine surgery using pressure changes. Conventionally, in devices where the rotating treatment member can be moved in the longitudinal direction of the backrest or bed to change the treatment area, rotational treatment is performed immediately upon receiving an input command to move. Since the rotation of the member was stopped and the rotation was started, the rotating treatment member sometimes moved while the amount of protrusion toward the human body was small. By the way, when the amount of protrusion is small, the pressure exerted by the rotating treatment member on the human body is also small, and therefore the user cannot clearly perceive the contact area of the rotating treatment member. For this reason, even though the user moves the rotating treatment member in order to change the area receiving the pine surge, the user may not be able to accurately move the rotating treatment member to the desired position. It was hot.

[Objective of the Invention] The present invention has been made in view of the above points, and its purpose is to enable the user to clearly sense the position of the rotating therapeutic member when moving the rotating therapeutic member, and to To provide a pine surgery machine capable of accurately positioning a rotating treatment member at a desired position.

[Disclosure of the Invention] The present invention provides a rotating treatment member eccentrically attached to a rotationally driven main shaft, a moving mechanism that makes the position of the rotating treatment member variable, and a rotation treatment member that protrudes in one direction. a detection means for detecting a change in the amount; an operating section for instructing selection of both rotation of the rotating treatment member and movement of the rotating treatment member by the moving mechanism; The pine surgery machine is equipped with a control circuit that controls movement by a movement mechanism and the operation, and the operation part includes a movement instruction part that outputs a movement instruction signal of the rotating treatment member only while the operation continues. , the control circuit increases the protrusion amount of the rotating treatment member by rotating the rotating treatment member under the monitoring of the detection means in response to the input of the movement instruction signal from the operation unit;
It is characterized in that it outputs an output to the moving mechanism only while a movement instruction signal is being input, and when the rotating treatment member is moved to a desired arbitrary position by giving a movement instruction input at the operation section. , the rotating treatment member is moved in a state where the amount of protrusion is large.

Next, the present invention will be explained in detail based on an illustrated embodiment in which a pine surge mechanism is incorporated into the backrest of a chair.
This chair has a pair of underframes 2 as legs
It is constructed of a backrest frame 1 and a seat frame 3, with the seat frame 3 disposed between both underframes 2, and the frame 1 connected to the seat frame 3. Both the frame 1 and the underframe 2 here are made of synthetic resin, and the seat frame 3 is made of a metal frame 30.
A support line 31 is installed on the support line 31 and
The fixing hook 32 is formed using a part of the. A seat cushion 33 placed on the seat frame 3 is supported by support lines 31 and attached by fixing hooks 32. Each under frame 2 is composed of an upper horizontal piece 22 provided with an armrest 23, a ground horizontal piece 21, and a front vertical piece 24 and a rear vertical piece 25 that connect these two pieces. It is fixed to the piece 24 and the rear vertical piece 25 with screws. The frame 1 of the backrest is pivoted to the rear end of the seat frame 3 by hinge plates 71 on both sides of the lower end, so that it can be reclined freely.
1 extends rearward, and wheels 29 are attached to the rear end of the horizontal grounding piece 21 to facilitate movement of the chair.

The frame 1 has a bottomed box shape with an open front, and has a vertically long reinforcing concave rib 12 formed in the center of the back, a recess 14 in the lower end of the back, and a bottomed box with an open front. Metal plates 9 are attached to both sides of the opening edge, respectively. This plate 9 has a raised hook 91 on its outer edge and a window 92 on its front surface.As shown in FIG. A travel path for the rollers 49 for travel guide of the pine surge mechanism is formed between the road surface 13 and the road surface 13. The front cover 8 attached to the front opening of the frame 1 has back cushions 20 attached to both sides and a pleat in the center, and the upper end is locked into the hook hole 18 at the upper end of the frame 1 with a hook spring 81. The back cushions 20 are engaged with the cut-and-raise hooks 91 and the windows 92 of the plate 9, so that both side edges are connected to both side edges of the frame 1. A connecting tab 82 extending from the center of the front cover 8 is folded back along the circumferential surface of a bar 76 installed between a pair of hinge plates 71 and connected to the lower end of a center belt 83 via a connecting spring 84. are connected. center belt 8
3 is a hook fitting 8 attached to the hook hole 18 at the upper end of the frame 1.
5 and is located at the rear of the center of the front cover 8. In addition, a headrest 1 is attached to the upper end of the frame 1.
0 is fixed to the boss 17 with a screw.
The reclining lever 75 is used to operate a gas spring (not shown) disposed between the recess 14 of the frame 1 and the rear lower end of the seat frame 3, and is operated when reclining the backrest. .

Now, the pine surge mechanism is housed in the frame 1, and the control box 65 is located on one side.
and the control box 65 and connection plate 67 on the other side.
A pair of wheels 4 are provided as rotating treatment members, which are eccentrically attached to the main shaft 5 in the same direction and inclined in opposite directions. Each ring body 4 is composed of an eccentric inner ring 41 fixed to the main shaft 5 and an outer ring 43 freely rotatable around the outer periphery of the eccentric inner ring 41. As is clear from FIG. 4, the main shaft 5 is a hollow pipe through which the drive shaft 6 is inserted, and cylinders 62 are fitted at both ends so as to freely rotate. The drive shaft 6 has cylindrical bodies 62 connected to both ends thereof, and the cylindrical bodies 62
is provided with rollers 49 that run on the running path and a pinion 48 that meshes with the rack 11 that is integrally formed with the frame 1. Rollers 49 are also provided in both control box 65 and gear box 66. A motor 47, which is the power source, is attached to the side of the gearbox 66, and selectively drives the main shaft 5 and the drive shaft 6 via a reduction gear within the gearbox 66. When the main shaft 5 is rotationally driven, the eccentrically inclined wheel 4 also rotates at the same time, and due to the eccentricity of the wheel 4, the amount of protrusion of the wheel 4 toward the front cover 8 side is changed periodically. Further, since the wheels 4 are inclined in opposite directions, the distance between the pair of wheels 4 at the contact portion with the front cover 8 is changed periodically. The combination of these two movements results in a fir tree surge to the human body. Note that the wheel body 4 does not need to be inclined. In this case, the change in protrusion amount becomes a pine surge similar to acupressure. If the drive shaft 6 is rotated in place of the main shaft 5, the entire pine surge mechanism is self-propelled in the vertical direction of the backrest due to the rotation of the pinion 48 that engages with the rack 11 of the frame 1 and the travel guide provided by 49. This self-propelling movement causes the wheel body 4, which is a rotating treatment member, to move, and by reciprocating within a certain range, the wheel body 4 rubs the back of the human body through the front cover 8, causing pine surgery. It is something to do.

Next, the speed reduction device within the gearbox 66 will be explained. The main speed reducer is a planetary differential speed reducer 50, and this speed reducer 50 is connected to the output shaft 5 of the motor 47.
1. Planetary roller 5 whose large diameter portion rolls on its outer surface
2. Consists of a first outer ring 53 in which the large diameter portion of the planetary roller 52 is inscribed, a second outer ring 54 in which the small diameter portion of the planetary roller 52 is inscribed, and a retainer 55 as a planetary carrier that supports the planetary roller 52. The first outer ring 53 and the second outer ring 54 are engaged with a gear 57 and a gear 58, respectively, supported by a shaft 56. Gear 59 rotates together with gear 57
is engaged with a gear 60 forming a torque limiter with the cylindrical body 62, and the gear 5
An elliptical gear 63 that rotates together with the main shaft 5 is meshed with an elliptical gear 64 fixed to the main shaft 5. Here, the main shaft 5 is connected via a pair of elliptical gears 63 and 64 so that when the amount of protrusion of the wheel body 4 toward the front cover 8 increases, the torque increases and the angular speed of rotation is slow. This is to increase the amount of time it takes to bend and press the human body. However, in the lever, the first
If the outer ring 53 is locked so that it does not rotate, differential rotation occurs in the second outer ring 54 due to the difference in diameter between the large diameter portion and the small diameter portion of the planetary roller 52, and this rotation is transmitted to the main shaft 5. , conversely, the second outer ring 5
4 is prevented from rotating, differential rotation occurs in the first outer ring 53 and is transmitted to the drive shaft 6.

The member for selectively blocking the rotation of the first outer ring 53 and the second outer ring 54 and switching the power of the motor 47 between the main shaft 5 and the drive shaft 6 is a solenoid.
This is a brake device 7 controlled by SOL and this solenoid SOL. This braking device 7 housed in a gearbox 66 includes a fixed hub 35, a pair of movable hubs 36 arranged on the left and right sides of the fixed hub 35, and an outer circumference and an inner circumference extending between each movable hub 36 and the fixed hub 35. a pair of left and right outer circumferential collars 37 and an inner circumferential collar 38 arranged respectively on the fixed hub 3;
5 and each movable hub 36, and a pinion 40 supported by the fixed hub 35 and connecting the outer collar 37 and the inner collar 38. Both outer peripheral collars 37 are connected to the solenoid SOL, one movable hub 36 is connected to the main shaft 5 by meshing with the gear 58, and the other movable hub 36 is connected to the main shaft 5 through the shaft 95 and gear 96. The drive shaft 6 is connected to the drive shaft 6 by meshing with the gear 57. Further, among the four coil springs 39, two coil springs located on the outer circumferential side and having different winding directions each have one end fixed to the fixed hub 35 and each other end fixed to each outer circumferential collar 37, and are located on the inner circumferential side. Two coil springs 39 with different winding directions each have one end attached to the fixed hub 35 and each end attached to each inner peripheral collar 3.
It is locked at 8. Note that the coil spring 39 on the outer circumferential side and the coil spring 39 on the inner circumferential side, which are in close contact with the outer circumferential surface and the inner circumferential surface of the movable hub 36 and the fixed hub 35, respectively, have different winding directions.

In this braking device configured as described above, when the solenoid SOL is in the returned state by the return spring 97, the inner and outer peripheral surfaces of the movable hub 36 and the fixed hub 35 to which the main shaft 5 is connected are As shown in FIG. 5, coil springs 39 are in close contact with each other to prevent the movable hub 36 from rotating.
and fixed hub 35, as shown in FIG. Since it is further wound around and has a smaller diameter and is separated from the circumferential surfaces of the movable hub 36 and the fixed hub 35, they are in a state where they are disconnected from each other and are therefore connected to the drive shaft 6. The movable hub 36 is in a free state. That is, at this time, the rotation of the motor 47 is transmitted to the drive shaft 6 after being decelerated by differential reduction by the speed reducer 50. When the solenoid SOL is activated, both outer collars 37 rotate, and the inner collar 38 also rotates via the pinion 40, causing each movable hub 36 and fixed hub 35 to rotate.
In order to reverse the connection by the coil spring 39 with the above case, the rotation of the movable hub 36 connected to the drive shaft 6 is locked, and the differential deceleration output of the motor 47 is transmitted to the main shaft 5. state.

This pine surge machine configured as above is
In order to control the operation, it is provided with a vertical position detection means for detecting the position of the wheel body 4 in the moving direction and providing feedback, and a detection means for detecting the amount of protrusion of the wheel body 4 toward the front cover 8 side. . First, let us explain the vertical position detection means.As is clear from FIG. 3, this is arranged inside the control box 65, and as shown in FIG. A gear 98 that meshes with the cylindrical body 62 and forms a clutch, this gear 9
8, a disk 72 that meshes with the gear 99 and rotates within one rotation within the vertical movement area of the wheel body, two arc-shaped holes 73, 74 formed in this disk 72, It is composed of a pair of sensors S ₁ and S ₂ with a light emitting part and a light receiving part facing each other, one sensor S ₁ is turned on through the hole 73 on the outer circumferential side of the disk 72, and the other sensor S ₂ is turned on through a hole 74 on the inner peripheral side. As is clear from FIG. 8, the positions of both holes 73 and 74 are shifted in the circumferential direction, and each sensor
The relationship between the on/off status of S ₁ and S ₂ and the movement range of the wheel body 4 is as shown in FIG. The upper and lower limits of the movement range and the approximate middle thereof are detected, and at the same time, it is also possible to detect in which region the wheel body 4 is located.

The detection means for detecting the amount of protrusion of the wheel body 4 detects the amount of protrusion by detecting the rotation angle of the main shaft 5 to which the eccentric wheel body 4 is attached. 11, a rotary plate 77 attached to the main shaft 5, a permanent magnet 78 fixed to the rotary plate 77, and a pair of reed switches and Hall elements arranged on the outer surface of the control box 65. Magnetically sensitive sensors S ₃ , S ₄
It is made up of. The sensor S ₃ is turned on by the permanent magnet 78 on the rotary plate 77 that rotates together with the wheel 4 when the amount of protrusion of the wheel 4 toward the front cover 8 is at its maximum, and the sensor S ₄ is turned on when the amount of projection of the wheel 4 toward the front cover 8 is at its minimum. It is turned on by a permanent magnet 78 when the The detection of the minimum amount of protrusion is carried out in order to ensure that the wheel body 4 has the minimum amount of protrusion when entering the "storage" state, which will be described later, and to prevent the wheel body 4 from colliding with the human body when sitting on the chair. It is something to do.

Now, in this pine surge machine, as mentioned above, there are two types of pine surge, one is the fir pine surge due to the rotation of the eccentrically inclined wheel 4, and the other is the rubbing pine surge due to the movement of the wheel 4.
It is possible to perform pine surge of seeds, and in pine surge, different pine surges (sideburns and sideburns) can be obtained depending on the direction of rotation of the wheel 4, but which of these pine surges can be performed? Operation part A for instructing
The code 8 is sent to the control circuit B in the control box 65.
0, and as shown in Fig. 12, there are three
Switch SW ₀ is a position changeover type, switch SW ₁ is for specifying pine pine surge, switch SW ₂ is for specifying sideburns, switch SW ₃ is for specifying sideburns, and manual reversal during pine surge. During the fir pine surge, a switch SW 4 moves the wheel ₄ upward only during the operation period to change the fir pine surge position, and a switch SW ₅ moves it downward. A control circuit B consisting of a microcomputer arranged in a control box ₆₅ controls the motor 47 and the solenoid SOL based on the input from each switch of the operation section A. It is. Note that the switches _SW1 to _SW5 are turned on only when pressing.

As shown in FIG. 13, the control circuit B includes a signal discrimination circuit C that discriminates which switch in the operating section A has been operated, a timer circuit D that counts the frequency of the commercial power supply and times out after a predetermined time, and a signal discrimination circuit C. Signal forming circuit E that sends the basic waveform for discrimination, counts the commercial power supply frequency and
7 and the solenoid SOL, a count circuit F that manages the activation timing of the motor 47 and the solenoid SOL, an operation instruction circuit G that instructs how to move the motor 47 and the solenoid SOL in response to signals from each circuit, and The motor drive circuit I and the solenoid drive circuit J include a light emitting element drive circuit H that drives the light emitting element of the _photocoupler in the solenoid drive circuit _J. , to which power supply circuit _V2 is connected. A specific circuit diagram is shown in FIG. V ₁ in the diagram
is the power supply circuit.

However, in this pine surge machine, the operation part A
When the switch SW ₀ is switched from "storage" or "stop" to "operation", the motor 47 starts to rotate clockwise, and the solenoid SOL is activated to connect the motor 47 and the main shaft 5 as described above, and to start the main shaft. In order to rotate 5, the sideburns pine surge is started, and the switch is turned off during this operation.
When SW ₃ is turned on, the direction of rotation of the motor 47 is reversed while the solenoid SOL remains in operation, so that the kneading massage for lowering the kneading is performed thereafter. However, as is clear from the timing chart shown in FIG. 15, the rotation direction of the motor 47 is reversed by the sensor _S3.
This is done after waiting for the switch to turn on, that is, when the amount of protrusion of the wheel 4 toward the front cover 8 is at its maximum. As mentioned above, a pair of elliptical gears 63 and 64 are interposed between the motor 47 and the main shaft 5, and when the amount of protrusion reaches the maximum, the reduction ratio becomes the largest, and from this state the motor 47 is started. This is because startup is becoming easier. Now, when the switch SW ₅ for moving the wheel body 4 downward is turned on during kneading and pine surge, the control circuit B
continues the rotation of the wheel body 4 until it receives a signal from the sensor S ₃ that the amount of protrusion of the wheel body 4 has reached the maximum;
After the sensor _S3 is turned on, the left rotation of the motor 47 is temporarily stopped, and then the solenoid SOL is turned off. After this, the motor 47 is rotated clockwise and the motor 4
7 rotation to the drive shaft 6 to start the downward movement of the pine surge mechanism. When switch SW ₅ is turned off, the clockwise rotation of the motor 47 is stopped as soon as the switch SW 5 is recognized as off, and after a short period of time, the solenoid SOL is turned on, and then the motor 47 is started to rotate counterclockwise, and switch SW ₅ is turned on. Resume the sideburn pine surge, which is the operation at the time it was done. When the switch SW ₄ is turned on instead of the switch SW ₅ , the only difference is the direction of rotation of the motor 47 during movement, and the other operations are the same. Also, when the lower or upper limit of the movement range is reached during movement, that is, when sensor S ₁ or sensor S ₂ is turned on, the motor 47 is immediately stopped to prevent overrun, and the switch SW is turned on. ₄ or switch
After turning off SW ₅ , restart the kneading pine surge at the lower limit or upper limit position. In any case, when the orbicularis 4 is moved to change the area that receives the massage, the orbicularis 4 is moved in the state of maximum protrusion, which is the state in which it is in the strongest contact with the human body, and the treatment is performed. The ring body 4 can be moved reliably and quickly to the desired part.

In addition, in the control device 7, there are a coil spring 39 on the inner circumferential side and a coil spring 39 on the outer circumferential side.
Although braking is performed in both directions of rotation,
During the movement described above, the wheel body 4 may rotate due to input from the load side and may no longer be in the state of maximum protrusion, but the movement continues, ignoring changes in the amount of protrusion during this movement. It's like this. In other words, the control circuit B controls the sensor S ₃ during the period when SW ₄ or SW ₅ is pressed, as shown in FIG.
When it is confirmed that _t1 is on for a certain period of time, it starts moving upward or downward, and even if sensor _S3 turns off during this movement as shown by the broken line in Fig. 16, the protrusion amount is set again. It continues to move without any problems. This is because once movement begins, if the movement is stopped midway to set the protrusion amount, the user will feel that a malfunction has occurred, and the movement will be against the user's will. We are trying to prevent this from happening. In addition, when changing the operation from massaging pine surge to movement, even if the rotation direction of the motor 47 during massaging pine surge and the rotation direction during movement are the same as described above, the motor 47 is temporarily stopped, and the solenoid SOL
After switching, the motor 47 is started again in the same direction, but this is because the power of the motor 47 is transferred to the main shaft 5.
A planetary differential type reducer 50 and a braking device 7 controlled by a single solenoid SOL are used to switch and transmit the signal to the drive shaft 6.The solenoid SOL is switched while the motor 47 is rotating. This is because mechanical noise is generated during this switching. The solenoid SOL is switched after a predetermined time t has elapsed since the motor 47 has stopped, and the motor 47 is also started after a predetermined time t has elapsed after the solenoid SOL has been switched. thing, motor 47
This is to prevent mechanical noise from occurring, taking into account the inertial rotation after the SOL stops and the delay in the mechanical operation of the solenoid SOL.

Now, when switch SW ₁ is turned on, this pine surge machine performs the previous massage pine surge, that is, continues the rotation of the wheel 4 for a while until the amount of protrusion reaches its maximum, and then stops the motor 47 and then turns on the solenoid SOL. The motor 47 is turned off, and after a predetermined time t, the motor 47 starts to rotate counterclockwise to move the wheel 4 upward. When the upper limit is reached, the rotation direction of the motor 47 is reversed and the movement starts downward. The minute pause time t of the motor 47 during this reversal is the time for waiting for the inertial rotation of the motor 47 to subside. When the movement reaches the lower limit, the direction of movement is reversed upward. By this movement of the wheel body 4, the wheel body 4 performs a massage in which the back muscles of the human body are continuously rubbed up and down. Switch SW ₄ and switch SW ₅ during the rasp pine surge function to reverse the movement direction at any position between the upper and lower limits of the movement range. In other words, switch while descending.
When SW ₄ is turned on, the direction of rotation of the motor 47 is reversed and the movement begins to rise.
If the switch SW ₅ is turned on during the ascent, the direction of rotation of the motor 47 is reversed at the moment the switch SW 5 is turned on, and the movement begins to descend.

Incidentally, in response to a double key operation, the rotation of the motor 47 is immediately stopped, and when the double key is released, the operation that was being performed until then is resumed. In this case, the solenoid SOL remains on even when it is on when it becomes a double key. Also, during the rasping pine surge, the amount of protrusion of the ring body 4 is set only at the beginning of the rasping pine surge, and even if the amount of protrusion reaches its maximum during the rasping pine surge, this is ignored and the rasping pine surge is continued. It is preferable to leave it there. Further, the pine surge may be performed not between the upper and lower limits of the entire movement range of the pine surge mechanism, but within a preset range, and this range may be changed. In this case, the range of the rubbing pine surge can be changed by specifying the movement of the wheel 4 using switches SW ₄ and SW ₅ , and the movement operation at this time is the same as that for the above-mentioned fir pine surge. Just do it.

When switch SW ₀ is set to "stop", control circuit B checks whether sensor S3 is on or off, and when it is on, that is, when the protrusion amount is maximum, motor 4
7 is stopped, and after a predetermined time t, the solenoid SOL is turned on or the solenoid SOL is kept on. If the amount of protrusion is not the maximum, the above operation is performed after the amount of protrusion is maximized by rotating the wheel body 4. When switch SW ₀ is set to "storage", first the protrusion amount of wheel 4 is maximized and then the wheel 4 is lowered, and then when the lower limit of the movement range is reached, sensor S 4 is turned on until sensor S ₄ is turned on. The wheel body 4 is rotated until the amount of protrusion of the body 4 becomes the minimum, and then the motor 47 is stopped. The solenoid SOL remains on after this and is turned off when the power switch SW in the power circuit _V1 is turned off.

Next, the diodes D ₁ , D ₂ , and D ₃ shown in the circuit in the operating section A will be explained. As is clear from the above, there are six switches in this operation section A, and switch SW ₀ is connected to other switches.
This should be given priority over switches SW ₁ to SW ₅ .
Incidentally, it is preferable that the cord 80 that connects the operating section A and the control circuit B has as few core wires as possible. From this point of view, Switch SW ₁ ~ Switch
When switch SW _{0 is inserted into the scanning matrix switch that constitutes SW 5 to} reduce the number of core wires, the diode D ₁ , as shown in Fig. 14,
Without D ₂ and D ₃ , there is a risk that the priority order of switch SW ₀ will be lost. For example, if switch SW _{1 ,} switch SW ₂ , and switch SW ₃ are pressed while switch SW 0 is in the center position, which is the "operation" position, switch SW ₀ will move to the "stop" position, which is on the left side of the figure, due to the rotation. The same signal will be sent to control circuit B as when the switch was pressed, and if switch SW ₅ and switch _{SW 3} are pressed when it is "stop", the path of switch SW ₅ , switch SW ₃ , and switch SW ₀ will be sent to control circuit B. In this case, the same signal as in the case of "storage" enters the control circuit B, causing a malfunction. However, the output port of control circuit B, switch _SW2 , and switch
Diodes D ₁ , D ₂ , and D ₃ inserted between SW ₅ and switch SW ₃ prevent the above-mentioned wraparound, and the number of core wires in cord 80 is reduced without destroying the priority of switch SW ₀ . It is. Furthermore, as shown in Fig. 17, in control circuit B, the timing at which the gates of the input ports are opened is delayed by a time Td from the rising edge of the scan pulse for these switch groups, which is apparently similar to the CR delay. This makes malfunctions caused by noise less likely to occur.

[Effects of the Invention] As described above, in the present invention, the rotating treatment member can be moved to a desired arbitrary position by the movement instruction signal that is output only while the movement instruction section in the operation section is being operated. When moving the rotating treatment member, the rotating treatment member increases its protrusion amount before starting to move. Therefore, while the rotating treatment member is moving, the contact pressure of the rotating treatment member against the user is high. , the user can clearly sense the position of the rotating treatment member, and therefore can accurately move the rotating treatment member to the desired position.
