Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a pine surgery machine, and particularly a driving means for pressing treatment elements arranged in a pair separated from each other in the direction of the human body, a moving means for moving them along the direction of the back muscles, and The present invention relates to a pine surger equipped with interval variable means for changing the interval between treatment elements in order to change the contact position. [Background Art] In general, "pressure points" on the back of the human body are distributed over almost the entire back surface. For this reason, it is preferable for a pine surgery machine to make the position of the treatment element variable so that all of these "pots" can be treated with pine surgery. There are things that have been done. This makes it possible to perform pine surgery over almost the entire back surface of the human body by making the spacing between the treatment elements set as a pair variable and making the treatment elements movable in a direction that intersects with the spacing between the treatment elements. In addition, this pine surgery machine is very easy to use because when you specify the shoulder or lower back position using the operating device, the treatment element automatically moves to that position and performs the pine surgery operation. By the way, from a treatment perspective, performing pine surgery in the direction along the blood flow, from the inside of the shoulder to the outside, or from the shoulder to the waist will improve blood circulation and be effective. It is known that pine surge can be obtained. However, in the conventional pine surgery machine mentioned above, although it is easy to use because the treatment element automatically moves to the designated area such as the shoulder or waist, the starting position of the treatment remains the same as the position at the end of the previous pine surgery. , and its position is not fixed, so when performing pine surge in the direction along the blood flow,
First, prior to treatment, move the treatment element to the shoulder position and narrow the gap between the paired treatment elements, then start treatment and move the designated area from the inside of the shoulder to the outside, or from the shoulder to the waist. It is difficult to say that it is easy to use because it takes time and effort to operate in order to obtain such an effective pine surge. Therefore, the current situation is that the user moves the treatment element randomly to each part according to his/her preference, and it is not always possible to obtain an effective pine surge from a treatment perspective. [Object of the Invention] The present invention has been made in view of the above points, and its purpose is to provide a pine surgery machine that can provide effective pine surgery without having to worry about moving the treatment child. There is something to do. [Disclosure of the Invention] Accordingly, the present invention provides treatment elements arranged in parallel as a pair spaced apart from each other, a drive means for pressing the treatment elements in the direction of the human body, and an interval variable means for changing the interval between the treatment elements. A treatment device comprising: a moving means for moving the treatment elements in a direction that intersects the direction in which the treatment elements are arranged, and in a vertical direction of a human body as a treatment object; a driving means, a distance variable means, and a control means for controlling the operation of the moving means; Upon input of the start signal, the control means:
The distance variable means and the moving means are controlled so that the drive operation position of the treatment element by the drive means is set to an upper side in the direction of movement of the treatment element by the movement means and to a side where the interval between the treatment elements is small, according to a preset procedure. The feature is that the treatment element is moved sequentially downward in the direction of movement of the treatment element and to the side where the interval between the treatment elements is larger, with the treatment element moving from the inside to the outside of the shoulder or from the shoulder The pine surge is performed while sequentially moving in the direction of the blood flow, from the lower back to the lower back. In addition, the movement in the direction along the flow of blood here is sufficient as long as the overall flow is the same, movement in the opposite direction may be in the middle, and it is not intended to restrict even minute movements. do not have. What kind of treatment element is used is arbitrary. Next, the present invention will be explained in detail based on illustrated embodiments. First, to explain from a structural point of view, the illustrated example has a pine surge mechanism built into the backrest of a chair. The lower end of the frame 1 is pivotally supported by the under frame 2, and a gas spring is installed between the frame 1 and the under frame 2, so that the backrest can recline. It is said to be free. A pair of guide rails 12 each having a U-shaped cross section and facing opening surfaces are fixed to both sides of the frame 1 of the backrest. Further, a headrest 13 is attached to the upper end of the frame 1,
A cover sheet 14 is attached to the front surface of the frame 1, and vertically long support belts 99 are arranged on both sides of the back surface of the cover sheet 14. Now, the pine surge mechanism has a control box 26 on one side.
and the control box 26 and the connecting plate 28 on the other side.
It also includes a pair of wheels 3, which are eccentrically attached to the main shaft 4 in the same direction and inclined in opposite directions, as treatment elements. Each wheel body 3 is composed of an eccentric inner ring 20 fixed to the main shaft 4 and an outer ring 21 freely rotatable around the outer circumference of the eccentric inner ring 20 via balls 22.
The inner circumference and outer circumference of the outer ring 21 have a large number of ribs 23.
connected by. As is clear from FIG. 4, the main shaft 4 is a hollow pipe through which the drive shaft 5 is inserted, and a cylindrical body 62 is fitted at both ends so as to freely rotate. The drive shaft 5 has cylinders 62 connected to both ends thereof, and the cylinders 62 have rollers 19 running on the guide rails 12 and pinions 18 that mesh with racks 11 attached to each guide rail 12. is provided. Rollers 19 are also provided in both control box 26 and gearbox 27. The motor M, which is the drive source, is connected to the stator 17 on the side of the gearbox 27.
The main shaft 4 and the drive shaft 5 are selectively driven via a speed reduction device in the gearbox 27. When the main shaft 4 is rotationally driven, the eccentrically inclined wheel body 3 also rotates at the same time, and due to the eccentricity of the wheel body 3, the amount of protrusion of the wheel body 3 toward the cover sheet 14 is changed periodically. Further, since the wheels 3 are inclined in opposite directions, the distance between the pair of wheels 3 at the contact portion with the cover sheet 14 is changed periodically. The combination of these two movements results in a fir tree surge to the human body.
Incidentally, depending on the direction of rotation of the wheel body 3, different massage treatments are performed. In other words, the portion of the wheel body 3 that protrudes from the main shaft 4 by a large amount is the cover sheet 1.
There are two types of massaging massage: one in which the back of the human body is pressed from the upper part to the lower part through 4 (kneading), and the other in which it is moved from the lower part to the upper part (brush raising). This is done depending on the direction of rotation. If the drive shaft 5 is rotated instead of the main shaft 4, the entire pine surge mechanism is self-propelled in the vertical direction of the backrest due to the rotation of the pinion 18 that engages with the rack 11 of the frame 1 and the travel guide provided by the pinion 19. This self-propelling causes movement of the wheel body 3, which is a treatment element, and by reciprocating within a certain range, the freely rotating outer ring 21 of the wheel body 3 covers the back of the human body with the cover sheet 14. It is meant to be rubbed through the pine serge. Furthermore, in this pine serge machine, the axial position of the wheel body 3 is
In other words, it is equipped with a mechanism that moves the pair of wheels 3 in the left-right direction to vary the width between the two wheels 3. This includes a feed screw 6 parallel to the main shaft 4 and the drive shaft 5,
It is composed of a pair of connecting arms 25 that connect this feed screw 6 and the inner ring 20 of each ring body 3.The feed screw 6, which is rotationally driven, has one right-hand threaded portion and the other left-hand threaded portion from the axial center. The connecting arm 25 has one end screwed into each threaded portion. The other end of both connecting arms 25 is connected to the inner ring 20 of each wheel body 3, and each inner ring 20 of both wheel bodies 3
0 is connected to the main shaft 4 by, for example, a spline so that it can slide freely in the axial direction, so the feed screw 6
The pair of wheels 3 move closer to each other or move away from each other as a result of the rotation. In this embodiment, when the feed screw 6 rotates, the main shaft 4 is also constantly rotating as will be described later, so a thrust bearing 98 is arranged at the connection between the connecting arm 25 and the inner ring 20. The connection is such that it can freely rotate. Further, regarding the movement of the two wheel bodies 3 in the direction in which the two wheel bodies 3 approach each other, the movement of the connecting arm 25 is transmitted to the wheel body 3 via the spring 97, so that, for example, the neck will not be pinched by strong force. Next, the speed reduction device inside the gearbox 27 will be explained. The main speed reduction device is a planetary mechanism 8 that performs differential speed reduction, and this planetary mechanism 8 includes an output shaft 51 to which the rotor 16 of the motor M is attached, a planetary roller 52 whose large diameter portion rolls on the outer surface of the output shaft 51, a first outer ring 53 in which the large diameter portion of the planetary roller 52 is inscribed;
The second outer ring 5 in which the small diameter portion of the planetary roller 52 is inscribed
4 and a retainer 55 as a planetary carrier that supports the planetary rollers 52. The first outer ring 53 and the second outer ring 54 are meshed with a gear 57 and a gear 58 supported by a shaft 56, respectively, and a gear 59 that rotates together with the gear 57 is engaged with the cylindrical body 62 as a torque limiter. An elliptical gear 63, which rotates together with the gear 58, is engaged with an elliptical gear 64 fixed to the main shaft 4. Here, the main shaft 4 is connected via a pair of elliptical gears 63 and 64 so that when the amount of protrusion of the wheel body 3 toward the cover sheet 14 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 this lever, if the first outer ring 53 of the planetary mechanism 8 is locked from rotating, differential rotation will occur in the second outer ring 54 due to the difference in diameter between the large diameter part and the small diameter part of the planetary roller 52. This rotation is transmitted to the main shaft 4, and conversely, if the rotation of the second outer ring 54 is prevented, differential rotation occurs in the first outer ring 53 and is transmitted to the drive shaft 5. The power transmission system to the feed screw 6 is configured such that the feed screw 6 is connected to the power transmission system to the main shaft 4 by an electromagnetic clutch 10. That is, the gear 58 provided between the planetary mechanism 8 and the main shaft 4
A connecting gear 61 for deceleration is engaged with the connecting gear 61, and an electromagnetic clutch 10 is further connected to this connecting gear 61. The electromagnetic clutch 10 housed in the gear box 27 has an outer input hub 82 and an inner input hub 81 whose outer circumferential surfaces are shaped like gears and mesh with the connecting gear 61, and an outer output hub 84 and an inner output hub as output members. 83, and an electromagnet 87 consisting of a coil 88, a yoke 89, and a cylindrical iron core 90.
An inner output hub 83 is fixed to a feed shaft 80 which is rotatably supported by a bearing at 7 and connected to the feed screw 6 at one end. input hub 8
An electromagnet 1 and an electromagnet 87 are respectively held on the feed shaft 80 so as to be freely rotatable. The inner input hub 81 and the outer input hub 82 are press-fitted and fixed to each other so as to form a double cylindrical shape, and a space for arranging a coil spring 86 is formed between them. Further, the outer output hub 84 and the inner output hub 83 are integrally formed by a protrusion at one end of the outer output hub 84 engaging a notch provided in a flange formed at one end of the inner output hub 83 on the electromagnet 87 side. are rotationally connected to each other. A space for arranging a coil spring 86 is also provided between the inner circumferential surface of the outer output hub 84 and the outer circumferential surface of the inner output hub 83, and a ring-shaped coil spring 86 located on the front surface of the flange is provided between the two. space is provided.
This space is a space for disposing a ring-shaped clutch 85 made of a magnetic material, and the electromagnet 87
The electromagnetic force causes the clutch 85 to come into contact with the clutch surface on the front surface of the flange.
The inner output hub 83 is made of a magnetic material at least at one end with a flange to form a magnetic circuit, and the outer output hub 84 is made of a non-magnetic material. The coil spring 86 has one end locked to the inner input hub 81 and the other end locked to the clutch shoe 85, and the coil spring 86 is configured to fit into the arrangement space between the outer input hub 82 and the inner input hub 81 and the outer output hub. 84 and the arrangement space between the inner output hub 83 and the inner output hub 83 . In the electromagnetic clutch 10 configured in this way, when the electromagnet 87 is not excited, the clutch shoe 85 is not in contact with the clutch surface.
Further, since the coil spring 86 is in a state where it is not in contact with either the inner peripheral surface of the outer output hub 84 or the outer peripheral surface of the inner output hub 83, the connection gear 61 that meshes with the outer input hub 82 is connected to the input hub 8
Even if rotational power is transmitted to 2 and 81, the coil spring 86 and clutch shoe 8
The output hubs 84 and 83 do not rotate, but are in a disconnected state, and therefore the feed screw 6 does not rotate. However, when the electromagnet 87 is excited to bring the clutch shoe 85 into suction contact with the clutch surface, resistance will be generated in the rotation of the clutch shoe 85 to which the coil spring 86 is connected. The diameter becomes smaller or larger depending on the direction of rotation. When the diameter becomes smaller, the coil spring 86 is moved to the inner output hub 8.
When the diameter becomes large, the rotational power is transmitted to the outer output hub 84 by being wrapped around the outer circumferential surface of the outer output hub 84. These output hubs 8
The rotation of 4 and 83 is taken out from the feed shaft 80 and rotates the feed screw 6. Now, the rotation of the first outer ring 53 and the second outer ring 54 in the planetary mechanism 8 is selectively prevented, and the motor M
The members for switching the power between the main shaft 4 and the drive shaft 5 are a single solenoid SOL and a braking mechanism 7 controlled by this solenoid SOL.
This braking mechanism 7 housed in the gear box 27 includes a fixed hub plate 30 into which the figures shown in FIGS. 7 to 9 are inserted, a pair of fixed hubs 31 fixed to both sides of the fixed hub plate 30 in the axial direction, 35
and a pair of movable hubs 32, 36 supported by the shaft 29 and arranged in the axial direction of each fixed hub 31, 35, arranged on an outer periphery and an inner periphery spanning each movable hub 32, 36 and fixed hub 31, 35, respectively. A total of four collars are arranged so as to be in contact with the inner and outer peripheral surfaces of the left and right pairs of outer collars 33, 37 and inner collars 34, 38, and the fixed hubs 31, 35 and the movable hubs 32, 36. Coil springs 41, 42, 4
3, 44, and fixed hubs 31, 35, are supported by a connecting shaft 39 to connect the internal gear portion 46 and gear portion 47 of the outer collar 33 and the inner collar 34, and the outer collar 37 and the inner collar 38. Both outer peripheral collars 33 and 37 are connected to a solenoid SOL disposed perpendicularly to the shaft 29, and one movable hub 32 meshes with the gear 58 to rotate the main shaft 4. The other movable hub 36 is connected to the drive shaft 5 by meshing with the gear 57 via the shaft 29 passing through each member and the gear 65. Further, among the four coil springs, two coil springs 42 and 44 located on the outer circumferential side and having different winding directions have an inner diameter smaller than the outer diameter of the fixed hubs 31 and 35 and the movable hubs 32 and 36. Two coil springs with different winding directions located on the inner circumferential side, each having one end engaged with the engagement hole 48 of the fixed hub plate 30 and each other end engaged with the engagement part 49 of each outer peripheral collar 33, 37. 41 and 43 are fixed hubs 3
1, 35 and the movable hubs 32, 36, one end of each is inserted into the engagement hole 48 of the fixed hub plate 30, and the other end is inserted into each of the inner peripheral collars 32, 38.
It is locked in the engaging part 49 of. The coil springs 41 and 42 are wound in the same direction, and the coil springs 43 and 44 are wound in the same direction. In this braking mechanism 7 configured as described above, when the solenoid SOL is in the returned state by the return spring 45, the inner peripheral surfaces of the movable hub 36 and the fixed hub 35 connected to the drive shaft 5 and A coil spring 4 is attached to the outer peripheral surface as shown in Fig. 9b.
The movable hub 32 and the fixed hub 31, which are connected to the main shaft 4, are shown in FIG. As shown in a, the diameter of the outer coil spring 42 is increased by the force of the return spring 45 via the outer collar 33, and the inner coil spring 41 is moved in the opposite direction to the outer collar 33 by the return spring 45. The state in which the inner circumferential collar 34, which rotates with force, is further wound in the winding direction and the diameter becomes smaller and is separated from the circumferential surfaces of the movable hub 32 and the fixed hub 31, so that the mutual connection is released. Therefore, the movable hub 32 connected to the main shaft 4 is in a free state. That is, at this time, the rotation of the motor M is transmitted to the main shaft 4 and then to the feed screw 6 after being decelerated by differential deceleration by the planetary mechanism 8. When the solenoid SOL is activated, the outer collars 33, 37 rotate in the direction indicated by the arrows in FIG. and fixed hub 31,3
Coil springs 41, 42, 43, 44 with 5
In order to reverse the connection described above, the rotation of the movable hub 32 connected to the main shaft 4 is locked, and the differential deceleration output of the motor M is transmitted to the drive shaft 5. In this braking mechanism 7, both movable hubs 32 and 36 are connected to the planetary mechanism 8 or to the main shaft 4 and drive shaft 5 at one end in the axial direction, thereby consolidating the arrangement of the braking force transmission system. . Also, as is clear from FIG. 9b, in this case, the movable hubs 32, 3 are in a free state.
Coil spring 4 when blocking rotation of 6
1, 42, 43, 44 are these and each color 3
The engagement with 3, 34, 37, and 38 is designed to have some play, and the rotation lock is not released until more than half of the stroke of the solenoid SOL has elapsed. In the middle of the process, a situation occurs in which the rotation of both movable hubs 32, 36 is locked. This is to prevent the wheel body 3 from rotating or moving up and down due to input from the load side during switching. In addition, when the power is turned off, the state is the same as when the solenoid SOL mentioned above is not energized.
In other words, since the movable hub 36 connected to the drive shaft 5 is in a locked state, the massaging mechanism does not descend under its own weight. However, if an excessive load is applied, such as when the pine surge machine is dropped, the clutch 9 will slip and allow the pine surge mechanism to descend, thereby absorbing this load. In other words, as shown in FIG. 10, the clutch 9 as a torque limiter includes the gear 60 which is detachably and slidably attached to the cylinder 62 and the gear which is fixed to the end of the cylinder 62. a meshing plate 91 that is adjacent to the gear 60 and has a meshing portion 90 that meshes with the gear 60 on one side;
1 and a spring 92 made of two discs that bias the gear 60 in the direction of engagement with the gear 60. Normally, the gear 60, which receives the rotation of the motor M which is the drive source via the planetary mechanism 8, and the meshing plate 91 are engaged with each other, so that the motor M
The decelerated rotation is transmitted to the drive shaft 5 to move the pine surge mechanism up and down. In addition, when the main shaft 4 is not in operation or when the main shaft 4 is rotating, the braking mechanism 7
Since braking is applied to the rotation of the pine surge mechanism, the pine surge mechanism does not descend under its own weight. However, if an excessive vertical impact such as a falling impact is applied, the gear 60 and the meshing plate 91 disengage against the spring 92 despite the braking by the braking mechanism 7, causing the cylindrical body 62 to disengage.
and the drive shaft 5 rotates. In other words, the pine surge mechanism is lowered. This lowering absorbs the impact and prevents excessive impact from being applied by the pine surge mechanism, and therefore there is no need for the strength of each member in the pine surge mechanism to be extremely high. Even if the gear 60 and the engagement plate 91 come out of engagement due to impact, the shape of the teeth of the engagement part 90 and the spring 9
It returns automatically by the spring pressure in step 2. The clutch 9 here is provided with a release means for manual disconnection to enable manual vertical movement when vertical movement becomes impossible due to some kind of failure.
This is a release plate 93 in contact with the other surface of the spring 92, and is provided with an engagement protrusion 95 that engages with an engagement recess 96 provided in a guide plate 94. When this release plate 93 is pulled out, the clutch 9 is released. It is something that That is, release plate 9
3, the spring 92 retreats and the gear 60 is disengaged from the engagement plate 91 in order to eliminate the force pressing the gear 60. In this state, the cylinder body 62 and the drive shaft 5 are rotated. ,
In other words, the pine surge mechanism is raised and lowered manually. When the release plate 93 is inserted and stopped on the guide plate 94, the gear 60 is pressed against the engagement plate 91 by the pressure of the spring 92, and returns to its original state. A system diagram of the above power transmission system is shown in FIG.
In the figure, double lines indicate a fixed connection, dashed lines indicate a sliding fit, and arrow lines indicate a system in operation. Also, figure a shows the case of vertical movement, figure b shows the time of fir pine surge, figure c shows the case of fir pine surge.
2 shows the case of width feed in which the wheel body 3 is moved in the axial direction. Furthermore, the relationship between the operations of the motor M, the solenoid SOL that operates the braking mechanism 7, and the electromagnetic clutch 10 and the operating state of the wheel 3 is shown in the table below.

[Table] Next, the position detection means for detecting the position of both wheels 3 will be explained. The position detection means includes a vertical position detection section J for detecting the position of the wheel body 3 in the moving direction, in the example shown, the vertical position, and a vertical position detection section J for detecting the width position of the wheel body 3 during width feeding. It is composed of three detection parts: a width position detection part H and a protrusion amount detection part T for detecting the amount of protrusion towards the cover sheet 14 due to eccentricity of the wheel body 3. First, it detects the vertical position. Starting from part J, this is disposed inside the control box 26, and as shown in FIGS. Push spring 75
A gear 69 constituting a meshing clutch energized by the gear 69, a gear 70 meshing with the gear 69, a disk 71 meshing with the gear 70 and rotating within one rotation within the vertical movement area of the wheel body 3, and a disk. 7
2. Two types of arc-shaped slits 73 with different diameters formed in the disk 71, sensors S ₁ and S ₂ whose light emitting parts and light receiving parts face each other across the disk 71, and the disk 7
2, the slit 7 has three different diameters.
4, and sensors S ₃ , S ₄ , and S ₅ whose light-emitting parts and light-receiving parts face each other with a disk 72 in between, and the sensor S ₁ is connected to a slit 73 on the outer circumferential side of the disk 71.
Sensor _S2 is turned on through the hole 73 on the inner circumference side of the disk 71, sensor _S3 is turned on through the outermost slit 74 of the disk 72, sensor _{S4 is turned on through the middle slit 74, and sensor S2} is turned on through the hole 73 on the inner circumference side of the disk 71. ₅ is turned on through the innermost slit 74. These slits 73 and 74 and each sensor S ₁ to _{S 5}
As shown in Figure 15, the vertical movement area is
A total of 31 points from Y ₀ to Y ₃₀ are detected. Incidentally, even if the clutch 9 is manually released and the pine surge mechanism is moved up and down, both discs 71,
72 is connected to the rotating drive shaft 5 and cylinder body 62 and rotates together with them even during manual up and down movement, so the absolute position of each detection point does not change. As shown in FIG. 14, the width position detection section H detects the position of one of the wheels 3 in the direction of the main shaft 4, and includes a detection plate 78 whose one end is fixed to the connecting arm 25, and this detection plate. It consists of three rows of slits 79 formed in 78, and sensors S ₆ , S ₇ , and S ₈ whose light emitting part and light receiving part face each other with a detection plate 78 in between, as shown in FIG. A total of 7 points from X ₀ to _{X 6} are detected. Furthermore, the first
In FIG. 5, the white line indicates the on range, and the black line indicates the off range. In addition, the shaded area indicates the movement area of the wheel body 3 in the vertical and width directions, and as is clear from the figure, the width of the lower half of the movement area is smaller due to the shoulder This is because if the maximum value of the movement range in the width direction of the orbicularis 3 is set according to the width direction and this is executed in the entire upper and lower area, there is a risk that the human kidneys will be compressed by the orbicularis 3. In order to avoid such dangers, a moving area as shown in the figure is set in a control circuit C, which will be described later. The protrusion amount detection unit T that detects the protrusion amount of the ring body 3 is
The amount of protrusion is detected by detecting the rotation angle of the main shaft 4 to which the eccentric wheel 3 is attached, and as shown in FIG. It consists of a permanent magnet 76 fixed to a plate 77, and a pair of magnetically sensitive sensors S _H and S _L such as reed switches or Hall elements arranged on the outer surface of the control box 26. And the sensor S _H is the cover sheet 14 of the wheel body 3.
When the amount of protrusion to the side is at its maximum, the permanent magnet 76 in the rotating plate 77 that rotates with the wheel body 3 is turned on, and when the amount of protrusion is at its minimum, the sensor S _L is turned on by the permanent magnet 76. It's summery.
The detection of the minimum amount of protrusion is carried out to ensure that the wheel body 3 is at the minimum amount of protrusion when entering the "storage" state, which will be described later, and to prevent the wheel body 3 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, two types of pine surge can be performed: a pine surge machine that uses the rotation of the eccentrically inclined wheel 3, and a rasp pine surge that uses the movement of the wheel 3. Massage and pine surge (sideburns and sideburns) that vary depending on the rotation direction of the wheel 3
The controller A for instructing which of these pine surges to perform is connected via a curl cord to a control circuit C composed of a microcomputer in the control box 26. As shown in Figure 17, there is a 3-position mode switch SW for switching between the three operating modes of ``storage,''``operation,'' and ``stop,'' and input of the sitting height of the human body. a sitting height setting switch SW <sub>3</sub> for changing the sitting height, a pattern changeover switch SW <sub>4</sub> for switching between the three movement program patterns of "whole body", "neck/shoulder", and "lower back" set in the control circuit C; Start switch SW <sub>5</sub> to start, within the entire vertical movement range (however, the upper end varies depending on the seat height supported by switch SW <sub>3</sub> )
Switch SW <sub>6</sub> to specify a back-stretching motion that performs a pine surge and automatically reverses the direction of movement at the upper and lower ends, and specifies partial rolling that performs an automatic reverse pine surge at any position within a specified amount of vertical range. Switch SW <sub>13</sub> ,
The switch SW <sub>7</sub> is used to specify sideburns, the switch SW <sub>8</sub> is used to set sideburns, and the wheel body 3 is moved upward only during the operation period to change the scraping pine surge and fir pine surge in partial rolling. The switch SW <sub>12</sub> and the switch SW <sub>11</sub> that move the wheels downward, the switch that moves the wheels 3 in the axial direction of the main shaft 4 only during the operation period to widen the distance between the pair of wheels 3.
It is equipped with a total of 12 switches including SW <sub>9</sub> and a narrowing switch SW <sub>10</sub> , and is also equipped with light emitting elements L <sub>2</sub> to <sub>L 7</sub> for displaying various operation modes. It should be noted that the switches <sub>SW5</sub> to <sub>SW13</sub> are all turned on only at the time of push. In order to reduce the number of connection lines between the controller A and the control circuit C, as shown in FIG.
The state of each switch SW <sub>2</sub> to <sub>SW 13</sub> is sent to the control circuit C through the signal forming circuit SC <sub>1</sub> and the transmitting circuit SC <sub>2</sub> in the auxiliary control circuit SC. The driving of L <sub>2</sub> to <sub>L 7</sub> is performed by a receiving circuit SC <sub>3</sub> receiving a recognition signal from a control circuit C, a signal discrimination circuit SC <sub>4</sub> , and a light emitting element driving circuit LD. The timer circuit SC <sub>5</sub> in this auxiliary control circuit SC prevents excessive pine surge in the event that the user falls asleep while receiving pine surge by limiting one pine surge to, for example, about 15 minutes. When time-up occurs, the signal forming circuit SC <sub>1</sub>
outputs the same signal as when mode switch SW <sub>2</sub> is set to "storage". RS is a reset circuit. Control circuit C is an auxiliary control circuit SC for the above-mentioned operating device A.
It controls the motor M, the solenoid SOL for the braking mechanism 7, and the electromagnetic clutch 10 based on the input from the receiving circuit <sub>C1</sub> , which receives signals from the auxiliary control circuit SC, as shown in FIG.

It is composed of a timing setting circuit <sub>C7</sub> that manages the operation timing of each load when sending the instruction to the motor drive circuit MD of <sub>C6</sub> and the electromagnetic member drive circuit ED, and includes the above-mentioned vertical position detection section J and width position detection section. H and a protrusion amount detection section T are connected. In the figure, V indicates a constant voltage circuit, SS indicates a surge absorption circuit, and RS indicates a reset circuit. A specific circuit diagram is shown in FIG. SW <sub>1</sub> is the power switch and L <sub>1</sub> is the power pilot lamp. However, in this pine surge machine, the controller A
If switch SW <sub>2</sub> is switched from "storage" or "stop" to "operation", the light emitting element L <sub>2</sub> of operation device A
lights up, and the control circuit C changes the width position of each load by driving the feed screw 6 so that the pair of wheels 3 come closest to each other, and then changes the width position to the maximum amount of protrusion detected by the sensor S <sub>H.</sub> The rear wheel body 3 rotates until it becomes, and this rear wheel body 3 corresponds to approximately the height of the human shoulder according to the sitting height level set by the sitting height setting switch SW <sub>3</sub> while maintaining the maximum protrusion amount.
Move to any of the upper or lower points from Y <sub>3</sub> to <sub>Y 9</sub> ,
Thereafter, at this upper and lower point, the wheel body 3 starts kneading pine surge for kneading, and at the same time, the light emitting element L <sub>6</sub> adjacent to the kneading switch SW <sub>8</sub> is turned on. The user determines whether the upper and lower points match his/her shoulders, and if they do not, operate the seat height setting switch SW <sub>3</sub> to reset the operating point of the kneading pine surge and move the wheel body 3. so that it aligns with your shoulder position. When the wheel body 3 moves to the above-mentioned upper and lower points, the reason why the wheel body 3 is first projected to the maximum extent is to allow the user to clearly recognize the position of the wheel body 3. . Furthermore, the upper limit of the vertical movement is automatically changed by the shoulder position adjustment here, that is, by the sitting height level set by the sitting height setting switch <sub>SW3</sub> . To explain the response of control circuit C to the sitting height level set with sitting height setting switch SW <sub>3</sub> ,
The sitting height level of the human body varies greatly from person to person. And if the sitting height level differs, not only the position of the shoulders but also the position of the waist to which the pine surge should be applied will differ. However, the position of the shoulders and the position of the waist or other positions of the human body have a substantially constant ratio relationship, and for example, if the positions of the shoulders are set and matched, the position of the waist can also be derived from the above ratio. Focusing on these points,
As shown in Fig. 19, if the sitting height setting switch SW <sub>3</sub> is set to , the upper limit of vertical movement will be set to Y <sub>6</sub> and the shoulder position will be set to Y <sub>9</sub> to correspond to the person with the lowest sitting height. If set to <sub>3</sub> , the upper limit of the vertical movement will be set to Y <sub>0</sub> and the shoulder position will be set to Y <sub>3</sub> to correspond to the person with the highest sitting height, and each other point will also be input from the sitting height setting switch SW <sub>3</sub> . It is automatically shifted accordingly. however,
The above points are automatically set only when executing the pine surge based on the movement program pattern, and when operating switch SW <sub>6</sub> , which manually performs the pine surge movement to stretch the back, the upper limit is set. When switches SW <sub>7</sub> , SW <sub>8</sub> and switch SW <sub>13</sub> are operated to execute the massage pine surge and the rasp pine surge of partial rolling, the upper limit becomes Y <sub>6</sub> regardless of the sitting height setting switch SW <sub>3</sub> . First, to explain the manual massage operation, if mode switch SW <sub>2</sub> is set to "operation" as described above, massage will start at the upper and lower points considered to be shoulder positions, depending on the set position of sitting height setting switch SW <sub>3</sub> . . If you want to move the kneading motion downward, for example at the waist, you can press switch SW <sub>11</sub> to specify "down". At this time, the wheel body 3 first reaches its maximum protrusion amount and then moves downward, and the vertical position is at the lower limit Y <sub>30</sub>
While holding down switch SW <sub>11</sub> until reaching
Continue descending. Then, by turning off the switch SW <sub>11</sub> , the kneading operation at that position is resumed. lower limit
If switch SW <sub>11</sub> is still pressed even after reaching Y <sub>30</sub> , the entire load is turned off and stopped at the lower limit Y <sub>30</sub> position, and after switch SW <sub>11</sub> returns, the kneading operation at the lower limit Y <sub>30</sub> position is resumed. . By the way, the kneading motion is an action that applies force to the human body from above to below, so it is effective for the shoulders, but sideburns are an action that applies force to the human body from below to above for areas other than the shoulders. Nomomi Pine Surge is more effective. Therefore, at this time, all you have to do is press switch SW <sub>7</sub> , which instructs you to raise your sideburns. Once the switch SW <sub>7</sub> is turned on, the direction of rotation of the motor M is reversed and the raising operation is started, and the light emitting element L <sub>5</sub> adjacent to the switch SW <sub>7</sub> is turned on. With this operating position, if you want to lower it downwards, you can press switch SW <sub>11</sub> , and if you want to raise it upwards, you can press switch SW <sub>12</sub> . In either case, while the switch SW <sub>11</sub> or switch SW <sub>12</sub> is pressed, the wheel body 3 moves downward or upward with the protrusion amount at its maximum, and when the switch SW <sub>11</sub> or switch SW <sub>12</sub> is released, the side-up operation starts. resume. Also, at this time, it will stop once it reaches the lower limit Y <sub>30</sub> , and as mentioned above, it will stop once at the maximum point Y <sub>0</sub> , regardless of the setting of seat height setting switch SW <sub>3</sub> , and then turn switch SW <sub>12</sub> off. Resume the sideburn movement. From the middle of this movement of raising or lowering your sideburns at any position, press the seat height setting switch.
When SW <sub>3</sub> is switched, the wheel body 3 is set as the seat height setting switch.
A state in which the shoulder position can be adjusted by moving to any of the up and down positions from Y <sub>3</sub> to <sub>Y 9</sub> , which are considered to be the new shoulder positions corresponding to the switching position set in SW <sub>3</sub> , and starting the lowering operation. shall be. FIG. 24 is a flowchart of the above operation. If you want to increase the distance between the pair of wheels 3, just press switch SW <sub>9</sub> . While the switch SW <sub>9</sub> is pressed, the electromagnetic clutch 10 is connected and the pair of wheels 3 move away from each other. And the limit of movement in this expanding direction x <sub>6</sub>
(However, as mentioned above, at a position below Y <sub>14</sub> , it is X <sub>4</sub> )
If the switch SW <sub>9</sub> is still pressed even after reaching the upper limit or the lower limit, the entire load is temporarily turned off and the raising operation is resumed after the switch SW <sub>9</sub> is turned off. When it is desired to narrow the distance between the pair of wheels 3, it is sufficient to press the switch SW <sub>10</sub> , and when the movement limit X <sub>0</sub> in the direction of narrowing is reached, the operation is the same as when each of the above limits is reached. In addition, when lowering the wheel 3 downward from a state where the wheel 3 is located above Y <sub>13</sub> and in the range of X <sub>4</sub> to X <sub>6</sub> , the wheel 3 will be lower than Y <sub>13</sub>
At this point, the distance between the wheels 3 is set to the X <sub>4</sub> position, and then the subsequent descent is continued. Next, I will explain the action of saramatsusaj, which stretches the back. When the switch SW <sub>6</sub> is turned on, the control circuit C first sets the distance between the pair of wheels 3 to <sub>the narrowest</sub> (position is set to the maximum, and then an automatic reversal vertical movement is performed between the upper limit and the lower limit, and the outer ring 21 of the ring body 3 starts a slapping motion in which it rolls along the back muscles of the back of the human body, and at the same time, the light emitting element L <sub>7</sub> is activated. Turn it on. however,
The lower limit of automatic reversal vertical movement is always Y <sub>30</sub> , but the upper limit is Y <sub>0</sub> depending on the switching position of seat height setting switch SW <sub>3</sub> .
and Y <sub>6</sub> . Fig. 25a shows a flowchart when the sitting height setting switch <sub>SW3</sub> is set, and Fig. 25b shows a flowchart when the sitting height setting switch <sub>SW3</sub> is set. When switch SW <sub>13</sub> is turned on to specify partial rolling, after setting the distance between the pair of wheels 3 to the narrowest (X <sub>0</sub> ) and setting the protrusion amount to the maximum (sensor S <sub>H</sub> on), switch SW <sub>13</sub> is turned on. The wheel body 3 starts automatic reversal vertical movement within a vertical range of 4 points upward and 4 points downward from the vertical point Yn of the wheel body 3 at the time of insertion, and the light emitting element <sub>L7</sub> is turned on. For example, wheel 3 is Y <sub>17</sub> when it is turned on.
When it is located between both points Y <sub>18</sub> , the automatic reversal range is 8 sections between Y <sub>14</sub> and Y <sub>21</sub> .
In addition, when this partial rolling is performed, the highest limit is always the <sub>Y0</sub> point regardless of the seat height setting switch SW <sub>3</sub> , and as is clear from the flowchart shown in Figure 26, when the rise exceeds the <sub>Y0</sub> point,
And when the descent exceeds <sub>Y30</sub> points, the vertical movement range is shifted downward or upward, respectively, so that a vertical movement range of 8 sections is secured even at this time. If you want to change this vertical movement range, you only need to turn on switch SW <sub>12</sub> or switch SW <sub>11.</sub> In this case, the center of the vertical movement range will be moved upward only in the section that has been raised or lowered by turning on switch SW <sub>11</sub> or switch SW <sub>12</sub> . Or return to the partial rolling sari pine surge action while shifting downward. For example, above 8
If the wheel body 3 is located near the upper limit of the vertical movement range of the section, and switch SW <sub>11</sub> is turned on to lower it by a small section, the vertical movement range will be determined around the new position. This is because, on the contrary, the range of vertical movement shifts upward. A pair of rings 3
If you want to change the interval, just insert switch SW <sub>9</sub> or switch SW <sub>10</sub> . However, in the case of the above-mentioned back-stretching sasuri-matsu-surge and this partial rolling sasuri-matsu-surge, in consideration of the movement area of the wheel body 3 mentioned above, it is necessary to prevent it from becoming wider than X <sub>5</sub> .
X <sub>4</sub> is the limit of movement in the direction of widening. If <sub>switch</sub> SW <sub>9</sub> or <sub>switch SW 10 is</sub> still on after reaching X <sub>4</sub> or Return to pine surge. When the mode switch SW <sub>2</sub> is set to "stop", the control circuit C stops the wheel 3 on the spot. When switch SW <sub>2</sub> is set to "storage", first raise wheel 3 to the maximum limit Y <sub>0</sub> , then increase the maximum interval (X <sub>6</sub> )
The rear wheel body 3 is moved to minimize the amount of protrusion of the rear wheel body 3 (sensor S <sub>L</sub> is on), and then the entire load is turned off. About 15 minutes have passed since mode switch SW <sub>2</sub> was set to "operation", and the auxiliary control circuit
Even when the SC timer circuit SC <sub>5</sub> times up,
Perform this storage operation. Now, the pine surge based on the operation program pattern will be explained below. The operation program pattern is based on the control circuit C, the operation position in the vertical direction and the width position (the vertical operation range), the operation content of either sideburn up, kneading down, or scraping pine surge, and the number of rotations or the number of up and down movements of the wheel body 3. It is stored in advance as a pattern table in which data consisting of a certain number of motions is written in the order of execution, and by switching the pattern changeover switch SW <sub>4</sub> , a pattern table corresponding to each pattern of "whole body", "neck/shoulder", and "waist" is created. is called and the start switch
When SW <sub>5</sub> is turned on, the data written in the pattern table is sequentially read into the control circuit C and executed. In particular, the upper and lower operating positions of this data are set by the seat height setting switch SW <sub>3</sub> . An action execution position is calculated according to the position, and the action is executed at the position based on this calculation. That is, if the mode switch SW <sub>2</sub> is set to "operation", the wheel body 3 starts the kneading operation at the up and down position considered to be the shoulder position according to the switching position of the seat height setting switch SW <sub>3</sub> , as described above. After the user confirms that the wheel 3 is aligned with his or her shoulder position, the user then turns the pattern changeover switch SW <sub>4</sub> .
All you have to do is set it to one of the three patterns mentioned above and press the start switch <sub>SW5</sub> . If it does not match, switch the sitting height setting switch SW <sub>3</sub> . By this switching, the control circuit C moves the wheel body 3 to one of the points Y <sub>3</sub> to Y <sub>9</sub> , which is set according to the switching position of the seat height setting switch SW <sub>3</sub> , as shown in FIG. After aligning the wheel body 3 with the shoulder position, perform the above operation. In this way, the pine surge based on the motion program pattern is started, and from then on, the motions registered in the motion program pattern selected by the pattern changeover switch SW <sub>4</sub> are sequentially performed. To explain the pine surge operation based on the operation program pattern, a flowchart in this case is shown in FIG. 23, and a movement locus of the wheel 3 is shown in FIG. 20. The numbers surrounded by circles in FIG. 20 indicate the operation order, and correspond to the numbers surrounded by circles in the flowchart of FIG. 23. In addition, the seat height setting switch SW <sub>3</sub> is shown in both figures.
shows the case where it is adjusted to the person with the highest sitting height. When the start switch SW <sub>5</sub> is turned on, the control circuit C first moves the wheels 3 in the axial direction so that the distance <sub>between</sub> the wheels 3 becomes Rotate the wheel 3 until <sub>the</sub> sensor S <sub>H</sub> turns on <sub>to</sub> maximize
Start doing masatsusurge to stretch your back. In other words, instead of suddenly giving the human body a strong stimulus like massaging pine surges, pine surges start with a weaker stimulus called rubbing pine surges. The number of vertical movements in the pine surge is counted by counting the signal that detects that the upper limit has been reached in the counting circuit <sub>C5</sub> of the control circuit C, and when it reaches a predetermined number of times, the next X <sub>0</sub> / Y <sub>0</sub> position, In other words, the movement moves to the kneading motion at the neck position, and when the number of rotations of the wheel body 3 detected by the sensor S <sub>H</sub> reaches the predetermined number <sub>of</sub> times,
The kneading operation at the Y <sub>1</sub> position is performed, and when this reaches a predetermined number of times, the kneading operation is performed at the X <sub>1</sub> and X <sub>3</sub> positions, and then the X <sub>5</sub> and X 3 positions.
Perform kneading at <sub>Y3</sub> position. After these series of kneading pine surge movements at the neck and shoulder positions, perform the rubbing pine surge once and repeat the X <sub>0</sub>・
Perform sideburns at Y <sub>0</sub> and X <sub>0</sub> /Y <sub>1</sub> positions,
After this, sideburn lifting is performed while moving the operating position sequentially downward from the shoulder position to the lower part along the back muscles. After the sideburn pine surge at the X <sub>1</sub> and Y <sub>30</sub> positions, the X <sub>3</sub> and
Pine surge of sideburns at certain positions Y <sub>23</sub> , Y <sub>26</sub> , Y <sub>29</sub> is performed. After the massaging massage that gives a strong stimulus to the human body is performed from the upper part to the lower part, and from the center of the body to the outer part, it is performed in each part such as the neck, shoulders, and lower back. In order to prepare the body, the massage at the X <sub>1</sub> position is repeated a predetermined number of times, and weak stimulation is applied to the entire body to complete the massage. Finally, the wheel body 3 is moved to the X <sub>6</sub> Y <sub>0</sub> position and the movement of the wheel body 3 is stopped with the amount of protrusion minimized, in the same way as when the mode switch SW <sub>2</sub> is set to "storage". As mentioned above, the above is when the sitting height setting switch SW <sub>3</sub> is set to suit the person with the highest sitting height, but when the sitting height setting switch SW <sub>3</sub> is set to, for example, as shown in Fig. 19. The vertical position in the above operation explanation is Y <sub>0</sub> to Y 3, Y 1 to Y <sub>3</sub> , and Y <sub>1</sub> to Y 3.
Y <sub>4</sub> , Y <sub>15</sub> to Y <sub>16</sub> , and so on are all executed with downward shifts. If the seat height setting switch <sub>SW3</sub> is switched after turning on the start switch <sub>SW5</sub> , the operation after this switching operation will be based on the newly set seat height level. When the pattern changeover switch <sub>SW4</sub> is set to "neck/shoulder" and the start switch <sub>SW5</sub> is turned on, the pine surge operation is performed in the order shown in FIG. 21. That is, it starts with pine surge, which gives a weak stimulation, called rubbing pine surge, and then moves to pine surge, which gives strong stimulation, called kneading pine surge. This kneading and pine surge is performed by sequentially shifting the operating position from the upper part to the lower part, and from the center of the body to the outer part. It should be noted that kneading is performed at the shoulder position, and kneading and pine surges at other parts are performed by kneading. And finally, after doing pine massage all over the body to prepare the body,
Move wheel 3 to storage position X <sub>6</sub> /Y <sub>0</sub> . When pattern changeover switch SW <sub>4</sub> is set to "waist" and start switch SW <sub>5</sub> is turned on, the 22nd
As shown in the figure, first perform the whole body sasurimatsusurge, then perform the sasurimatsusurge on the area below Y <sub>20</sub> , and then move up and down several times to perform <sub>the</sub>
Perform sideburn pine surge at one position to loosen the center of the body, and then perform sideburn pine surge while changing the operating position from the center to the outside and from upward to downward. After giving a strong stimulation to the lower back with the sideburn pine surge, the lower half is first rubbed, then the whole body is rubbed, and finally the wheel body 3 is moved to the storage position. Furthermore, Figs. 21 and 22 also show the case where the seat height setting switch SW <sub>3</sub> is set to , and when the seat height setting switch SW <sub>3</sub> is set to another position, the upper and lower points are as shown in Fig. 19. For example, press the seat height setting switch SW <sub>3</sub> at the indicated point.
is set to <sub>Y20</sub> , the point at Y20 is shifted to the point at <sub>Y22</sub> and the pine surge operation is performed. As is clear from the above explanation of the operation, in this pine serge machine, no matter what position the pattern changeover switch SW <sub>4</sub> is placed in, the pine surge, which is the main body of the pine surge operation performed based on instructions from the control circuit C, is always performed. It is based on movement from the top to the bottom and from the center to the outside, and by performing this movement, the ``pressure points'' in each part of the human body are sequentially massaged. It goes without saying that each position at which the wheel body 3 performs massage is set with reference to the "pressure points" of the human body. In addition, in this example, the ring body 3
The rasp pine surge obtained by moving with the rotational drive stopped is an additional functional function and is not essential to the present invention. [Effects of the Invention] As described above, in the present invention, when performing pine surgery on each "point" of the human body, blood from the heart of the human body is pumped from the top to the bottom and from the center to the outside. This technique is extremely effective because it involves pine surgging each ``acupoint'' one after the other in the order that follows the flow, and pine surges each ``acu'' evenly and in the order that increases the pine surge effect. It is possible to obtain a high pine surge, and it does not require any effort to move the treatment element.
