〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 15.

The pine surge machine of this embodiment has a pine surge mechanism built into the backrest of a chair.

The chair has a pair of underframes 2 as legs.
It is constituted by a backrest frame 1 and a seat frame 3, and the seat frame 3 is disposed between both underframes 2, and the frame 1 is connected to the seat frame. The frame 1 and the under frame 2 are both 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 a fixing hook 32 is formed using a part of the support line 31. A seat cushion 33 placed on the seat frame 3 is supported by the support line 31 and attached by a fixing hook 32. Each underframe 2 is composed of an upper horizontal piece 22 provided with an armrest 23, a grounding horizontal piece 21, and a front vertical piece 24 and a rear vertical piece 25 that connect these two pieces. The seat frame 3 is fixed to a front vertical piece 24 and a rear vertical piece 25 with screws. And frame 1 is seat frame 3
The hinge plates 71 on both sides of the lower end are pivoted to the rear end and can be reclined freely. Therefore, the grounding horizontal piece 21 of the under frame 2 extends greatly rearward, and the rear end of the grounding horizontal piece 21 The chair is equipped with wheels 29 to facilitate movement of the chair.
is installed.

The frame 1 has a box shape with an open front and a bottom, and a vertically long reinforcing convex rib 12 is formed at the center of the back surface, and a recess 14 is formed at the lower end of the back surface. . Further, metal plates 9 are attached to both sides of the front opening edge, respectively. This plate 9 has a raised hook 91 on the side edge and a window 92 on the front side, and is formed integrally with the frame 1 on both sides of the front side of the frame 1, as shown in FIG. A running path for rollers 49 for guiding the pine surge mechanism is formed between the running road surface 13 and the plate 9. 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. The back cushions 20 are engaged with the cut-and-raise hooks 91 and the windows 92 of the plate 9, respectively, so that the back cushions 20 are connected to both side edges of the frame 1. A connecting tab 82 extending from the center of the lower end of the front cover 8 connects the bar 7 installed between the pair of hinge plates 71.
6 and is connected to the lower end of the center belt 83 via a connecting spring 84.
The center belt 83 is fastened to the hook hole 18 at the upper end of the frame 1 with a hook 85 and is located at the center back of the front cover 8 . Further, a headrest 10 is fixed to the upper end of the frame 1 by screws to a boss 17. 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. It is something.

The massaging mechanism is housed within the frame 1, and has a control box 65 on one side and a gear box connected to the control box 65 by a connecting plate 67 on the other side, as shown in FIGS. 3 and 4. 66, and a pair of wheels 4 attached to the main axis as rotating treatment members so as to be inclined in the same direction and in opposite directions. Each wheel body 4 has an eccentric inner ring 41 fixed to the main shaft 5.
and an outer ring 43 freely rotatably disposed around the outer periphery of the outer ring. As is clear from FIG. 4, the main shaft 5 is a hollow pipe into which the drive shaft 6 is inserted, and a first cylindrical body 61 is disposed at one end and a second cylindrical body 62 is disposed at the other end. They are fitted so that they can freely rotate. The first cylindrical body 6 is attached to one end of the drive shaft 6.
1 is connected to the other end, and a second cylinder 62 is connected to the other end, and the first cylinder 61 and the second cylinder 6 are connected to each other.
2 each have a roller 49 running on the running path.
and a rack 1 integrally formed with the frame 1.
A pinion 48 that meshes with 1 is provided.
Rollers 49 are also provided in both the control box 65 and gear box 66. A motor 47 serving as a driving means is attached to a side surface 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 body 4 also rotates at the same time, and the eccentricity of the wheel body 4 causes the amount of protrusion of the wheel body 4 toward the front cover 8 to be periodically changed. Furthermore, since the wheels 4 are inclined in opposite directions, the pair of wheels 4
The distance at the contact portion between the front cover 8 and 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 have to be inclined. In this case, the change in protrusion amount results in pine surge similar to acupressure. By the rotation of the pinion 48 that engages with the rack 11 of the frame 1 and the travel guide provided by the rollers 49, the entire pine surge mechanism is self-propelled in the vertical direction of the backrest. This self-propelling causes the wheel body 4, which is a rotating treatment member, to move, and by reciprocating within a certain range, the wheel body 4 covers the back of the human body through the front cover 8. It is meant to rub the pine.

The speed reduction device within the gearbox 66 will be explained. The main speed reduction device is a planetary differential speed reduction gear 50, and this speed reduction gear 50 consists of an output shaft 51 of a motor 47, a planet roller 52 that rolls on a large diameter portion on the outer periphery of the output shaft 51, and a planetary differential speed reduction gear 50. It is composed of a first outer ring 53 in which the diameter portion 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. First outer ring 53 and second outer ring 54
are a gear 57 and a gear 5 supported by a shaft 56, respectively.
It is engaged with 8. A gear 59 that rotates together with the gear 57 is engaged with an upper and lower gear 60 that forms a torque limiter section with the cylindrical body 62, and this upper and lower gear 60 is engaged with a pressing spring 86.
A clutch plate 70 is interposed between the upper and lower gears 60 and the gear 69. The gear 69 is fixed to the drive shaft 6, and is connected to the upper and lower gears 60 and the clutch plate 70.
and constitute the torque limiter section. A disc-shaped gear 63 that rotates together with the gear 58 is meshed with a disc-shaped gear 64 fixed to the main shaft 5. However, in the lever, if the first outer ring 53 of the reducer 50 is locked from rotating, differential rotation occurs 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. The rotation of the lever is transmitted to the main shaft 5. Conversely, if the rotation of the second outer ring 54 is prevented, the first
Differential rotation occurs in the 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 to the main shaft 5 and the drive shaft 6 is a solenoid.
SOL and a braking device 7 controlled by this solenoid SOL. The braking device 7 housed in the gearbox 66 includes a fixed hub 35 and a pair of movable hubs 36 disposed on the left and right sides of the fixed hub 35.
, a pair of left and right outer circumferential collars 37 and an inner circumferential collar 38 disposed on the outer circumference and inner circumference of each movable hub 36 and fixed hub 35, respectively, and 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, and one movable hub 3 is connected to the solenoid SOL.
6 meshes with a gear 58 and is connected to the main shaft 5, and the other movable hub 36 meshes with a gear 57 and is connected to the drive shaft 6 via a shaft 95 and a gear 96. 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 engaged with the fixed hub 35 and each other end engaged with each of the outer circumferential collars 37, and the inner circumferential side Two coil springs 39 having different winding directions are fixed at one end to the fixed hub 35 and at the other end to each inner collar 38 . Note that the coil spring 39 on the outer circumferential side and the coil spring 39 on the inner circumferential side that are in close contact with the outer and inner circumferential surfaces of the movable hub 36 and the fixed hub 35 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, it is connected to the main shaft 5.
As shown in FIG. 5, the coil springs 39 are in close contact with the inner and outer peripheral surfaces of one movable hub 36 and fixed hub 35, respectively, to prevent rotation of one movable hub 36, It is also connected to the drive shaft 6. The other movable hub 36 and the fixed hub 3
5, as shown in FIG.
is further wound in the winding direction by the inner circumferential collar 38 and has a smaller diameter, and the other movable hub 36
And because it is away from the peripheral surface of the fixed hub 35,
The two movable hubs 36 are disconnected from each other, and therefore the other movable hub 36 connected to the drive shaft 6 is free. 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 reducer 50.
And when the solenoid SOL is activated,
As both outer circumferential collars 37 rotate, the inner circumferential collar 38 also rotates via the pinion 40, and the coil springs 39 of each movable hub 36 and fixed hub 35 are rotated.
In order to reverse the connection described above, the rotation of the other 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.

This pine surge machine configured as above is
In order to control the operation, there is a vertical position detection means for detecting the position of the wheel body 4 in the moving direction and providing feedback, and a means for detecting the protrusion of the wheel body 4 toward the front cover 8 side, that is, the rotational position of the wheel body 4. and a detection means for detecting.

First, the vertical position detection means will be explained. As shown in FIGS. 7 and 8, a disk 72 engages with the upper and lower gears 60 via a gear 98 and rotates within one rotation within the vertical movement area of the wheel body 4;
Two arcuate holes 73, 74 formed in 2
and a pair of sensors S ₁ and S ₂ with a light emitting part and a light receiving part facing each other with a disk 72 in between, one sensor S ₁ is turned on through a hole 73 on the outer circumferential side of the disk 72, and the other sensor The sensor S ₂ is turned on through a hole 74 on the inner circumferential side. Here, both holes 7
As is clear from Fig. 8, the positions of 3 and 74 are shifted in the circumferential direction, and the relationship between the on/off status of each sensor S ₁ and S ₂ and the movement range of the wheel 4 is shown in Fig. 9. It's becoming like that. The upper limit, the lower limit, and the middle of the moving range are detected, and at the same time, it is possible to detect in which region the wheel body 4 is located. If a falling impact is applied to the pine surge machine, the disc 72 and pinion 48
In this case, when the wheel body 4 is moved upward or downward, it moves beyond the upper and lower limits in the conventional pine surge machine.
The pinion 48 sometimes hit stoppers (not shown) formed at the upper and lower ends of the rack 11 and became locked. In this embodiment, even if the pinion 48 hits the stopper and stops, since the clutch plate 70 is interposed between the upper and lower gears 60 and 69, the clutch plate 70 will slip, and the upper and lower gears 60 will Continue rotating. The vertical gear 60 continues to rotate until the sensor S ₁ is turned on, and the pinion 48 is stopped during that time. Therefore, the discrepancy in the relative position between the disk 72 and the pinion 48 is corrected, and the wheel body 4 can be moved up and down accurately. The position can now be detected.

The detection means for detecting the rotational position of the wheel body 4 includes a third
4, 10, and 11, a rotating plate 77 attached to the main shaft 5, 15 arc-shaped holes 78 formed in this rotating plate 77,
A rotating plate 77 is arranged on the outer surface of the control box 65.
The sensor S ₃ has a light-emitting part and a light-receiving part facing each other with
It is composed of S ₄ , S ₅ , and S ₆ . Each of the sensors S ₃ to _{S 6} receives a signal of 1 when the optical signal from the light emitting section is input to the light receiving section through the hole 78, that is, when it is turned on, and when the optical signal is blocked by the rotary plate 77, it is input to the light receiving section. If not, a 0 signal is generated, and the rotational position of the wheel body 4 is detected by a combination of 1 and 0 signals generated by the respective sensors S ₃ to _{S 6} . For example, as shown in FIGS. 10 and 15 a and b, the ring body 4
When the rotating position is the maximum amount of protrusion of the wheel 4 toward the front cover 8, the signals generated by the sensors _S3 to _S6 are 1, 1, 0, and 1, respectively, as shown in FIGS. As shown in FIGS. 15a and 15b, when the rotational position is such that the amount of protrusion of the wheel body 4 toward the front cover 8 side is the minimum,
The signals generated by each sensor S ₃ to _{S 6} are 1,
It is 1,0,0.

Here, as shown in FIG. 15b, 1 of the ring body 4
The rotational position of the rotation is divided into 16 equal parts corresponding to the combinations of the 1 and 0 signals, and as shown in FIG. 15c, the rotational speed of the motor 47 is preset corresponding to each rotational position. . A plurality of correspondences between the rotational speed and the rotational position _of the wheel body 4 are set and stored in a pattern setting circuit M, which will be described later. By extracting the correspondence, multiple types of kneading patterns can be obtained.

Now, in this pine surge machine, two types of pine surge can be performed: pine surge by rotating the eccentrically inclined wheel 4 and rasping pine surge by moving the wheel 4, as described above. , different kneading pine surges (sideburns and kneading) can be obtained depending on the direction of rotation of the wheel body 4, but the operation section A for instructing which pine surge among these is to be performed is located in the control box 65. is connected to the control circuit B of the twelfth circuit via a cord 80.
As shown in the figure, there is a three-position switch SW ₀ for "storage", "operation" and "stop", a switch SW ₁ for specifying pine surge, a switch SW ₂ for specifying sideburns, A switch SW ₃ for specifying kneading lowering, and a switch SW 3 which functions as a manual reversal during the rubbing pine surge, and moves the wheel body 4 upward only during the operation period to change the massaging position during the rubbing pine surge. This includes a switch SW ₄ for moving the massager downward, a switch SW ₅ for moving the massager downward, a switch SW ₆ for switching and selecting a kneading pattern, and a light emitting element L ₁ . Based on the inputs from each switch of the operation section A, a control circuit B consisting of a microcomputer disposed in the control box 65 controls the motor 47.
and solenoid SOL. still,
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;
A signal forming circuit E that sends a fundamental frequency for discrimination to the signal discrimination circuit C, a counting circuit F that counts the commercial power supply frequency and manages the activation timing of the motor 47 and the solenoid SOL, and a motor 47 that receives signals from each circuit. and an operation instruction circuit G that instructs how to move the solenoid SOL, a light emitting element drive circuit H that drives the light emitting element of the photocoupler in the motor drive circuit I and the solenoid drive circuit J, the rotational position of the wheel body 4, and the rotation of the motor 47. A pattern setting circuit N is provided as a setting means for setting and storing a plurality of different correspondences with the speed and outputting one of the plurality of correspondences to the operation instruction circuit G. In addition, the operation part A,
Vertical position detection circuit K composed of sensors S ₁ and S ₂
, a rotational position detection circuit L composed of sensors S ₃ to _{S 6} , a D/A conversion circuit P that converts the digital signal of the control circuit B into an analog signal, and a voltage signal from the D/A conversion circuit P. A voltage-frequency conversion circuit Q, which converts the frequency into a voltage and frequency for rotating the motor 47, and a power supply circuit _V1 are connected. The rotational position of the wheel 4 is detected by the rotational position detection circuit L, and the operation instruction circuit G as a rotational speed control means detects the rotational position of the wheel 4 and the motor 47 set by the pattern setting circuit M. Based on the correspondence relationship with the rotational speed, the rotational speed corresponding to the detected rotational position is instructed to the motor drive circuit I.

The operation of this embodiment will be explained below.

If switch SW ₀ on operation unit A is switched from "storage" or "stop" to "operation", motor 4
7 starts clockwise rotation at the rotational speed according to the instruction of switch SW ₆ , and the solenoid SOL is activated to connect the motor 47 and the main shaft 5 as described above, and to rotate the main shaft 5, the sideburns are kneaded. This is what starts the pine surge. If switch SW ₃ is turned on during this operation, solenoid SOL
Since the rotational direction of the motor 47 is reversed while the motor 47 continues to operate, the kneading pine surge for kneading is performed thereafter. Also, at this time, the switch SW ₆ , which is an operation means for switching and selecting an arbitrary positional relationship between the rotational position of the wheel 4 from the pattern setting circuit M and the rotational speed of the motor 47, is used to select the pattern 1 to pattern 1. When switching between 5 and 5, the pine surge of the tamami pattern is performed according to the instruction. For example, Figure 15c
If you select the rotational speed pattern shown by the solid line in Figure 15d, you will perform the fir surge of the rotational speed pattern shown by the solid line in Figure 15d, and if you select the rotational speed pattern shown by the broken line in Figure 15c, then the rotational speed pattern shown by the broken line in Figure 15d will be applied. Compared to the kneading pattern shown by the broken line, that is, the solid line, the kneading pattern can be performed more gradually when applying force and more sharply when releasing the force. As is clear from the timing chart shown in FIG. 14, the rotation direction of the motor 47 is reversed by waiting for sensor _S3 to turn on, sensor _S4 to turn on, sensor _S5 to turn off, and sensor _S6 to turn on.
In other words, the process is performed in a state where the amount of protrusion of the wheel body 4 toward the front cover 8 side is maximized. Now, when the switch SW ₅ for moving the wheel body 4 downward is turned on during kneading pine surge, the control circuit B receives a signal from the sensors S ₃ to _{S 6} indicating that the amount of protrusion of the wheel body 4 has reached the maximum. The rotation of wheel 4 continues until sensor S ₃ is turned on, sensor S ₄ is turned on, sensor S ₅ is turned off, sensor
After turning on _S6 , first, the counterclockwise rotation of the motor 47 is temporarily stopped, and then the solenoid SOL is turned off. Thereafter, the motor 47 is rotated clockwise to transmit the rotation of the motor 47 to the drive shaft 6, and the pine surge mechanism starts to move downward. When the switch SW ₅ is turned off, the motor 47 is turned off as soon as it is recognized that the switch SW 5 is turned off.
The clockwise rotation of the solenoid is stopped, and after a short period of time the solenoid
SOL is turned on, and then the motor 47 starts rotating to the left, and the kneading pine surge, which is the operation at the time the switch SW ₅ was turned on, is resumed. 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, while moving in this way, the lower limit of the movement range,
Or when the upper limit is reached, that is, when sensor S ₁ is on and sensor S ₂ is on, the motor 47 is immediately stopped to prevent overrun,
Then, after switch SW ₄ or switch SW ₅ is turned off, massaging pine surge is restarted at the lower limit or upper limit position. In any case, when moving the ring body 4 in order to change the area that receives massage massage, the ring body 4 is in the state of being in the strongest contact with the human body, and the ring body 4 can be moved to the area where you want to receive treatment.
can be moved reliably and quickly.

Now, when switch SW ₁ is turned on, this pine surge machine continues the previous pine surge, that is, 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. is turned off, and after a predetermined time t, the motor 47 starts rotating 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 as follows:
This is the time to wait for the inertial rotation of the motor 47 to stop. 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.
If SW ₄ is turned on, at the moment it is turned on,
The direction of rotation of the motor 47 is reversed to move up, and if the switch SW 5 is turned on while the switch SW ₅ is being turned on, the direction of rotation of the motor 47 is reversed and the move is moved down.

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, even during the rasping pine surge, the protrusion amount of the wheel 4 is set only at the beginning of the rasping pine surge, and even if the protrusion amount is no longer at its maximum during the rasping pine surge, this will be ignored and the rasping pine surge will continue. It is preferable to do so. Furthermore, 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 changeable. In this case, switch SW ₄ to switch SW ₅
The range of the rubbing pine surge may be changed by specifying the movement of the wheel body 4, and the moving operation at this time may be the same as the moving operation for the above-mentioned fir pine surge.

When switch SW ₀ is set to "stop", control circuit B checks whether sensor S ₃ is on, sensor S ₄ is on, sensor S ₅ is off, sensor S ₆ is on, and the protrusion amount of wheel 4 is determined. is the maximum, the motor 47 is stopped and the solenoid SOL is activated after a predetermined time t.
or keep solenoid SOL on. If the amount of protrusion of the wheel body 4 is not the maximum, the above operation is performed after the amount of protrusion is maximized by rotating the wheel body 4. "Storage" the switch SW ₀
In the _{case of}
is on, sensor S ₅ is off, and sensor S ₆ is off, that is, until the amount of protrusion of the wheel 4 is minimized, the rotation of the wheel 4, which is a kneading and pine surge operation, is performed, and then Motor 47 is stopped. The solenoid SOL remains on after this,
It is turned off by turning off the power switch SW in the power supply circuit _V1 .
