Description

[Detailed description of the invention]

[Technical Field 1] This relates to a pine surge machine that performs pine surge. [Background Art] There is a pine massage machine whose treatment elements are a pair of ring-shaped objects attached at a distance to a rotationally driven main shaft. The above-mentioned treatment element, which is attached eccentrically and inclined with respect to the main shaft, performs a massage operation by rotation of the main shaft. However, with a massager shaped like this, the amount of protrusion of the massager from the main axis is determined only by the outer diameter and eccentricity of the massager, and as the outer diameter is increased, the curvature of the outer surface of the massager becomes smaller. This causes the problem that the contact area with the body becomes large, so it is impossible to obtain the so-called point pine surge that suppresses the "bubba", and even if the amount of eccentricity is increased, this is limited by the outer diameter. The same is true for receiving. Therefore, when trying to perform pine surgery on the sides of the neck or shoulders using a treatment element whose outer diameter is set to a point pine surge, the main axis hits the rear part of the neck. On the other hand, Japanese Utility Model Publication No. 55-30488 discloses an arm that is connected to an eccentric inclined plate attached to a main shaft and moves as the main shaft rotates, and a treatment element 4 is attached to the tip of this arm. has been done. Since there is no separate limit on the length of the arm, the configuration is such that both point pine surge and pine surge on the sides of the neck and shoulders can be satisfied. However, this pine surger also has the following problems because it is difficult to adjust the amount of protrusion of the treatment element from the main shaft. In other words, if the amount of protrusion from the main axis of the treatment element is the same when performing pine surgery on the side of the neck or shoulders and when performing pine surgery on the back or lower back, it is difficult to perform appropriate pine surgery on each part. If this is not possible and the amount of protrusion of the treatment element is determined according to the eyebrows, the pine surge on the back of the neck, back, lower back, etc. will become too strong, which is dangerous. Then, the pine surge on the eyebrows becomes too weak. [Object of the Invention] The present invention has been made in view of the above points, and its purpose is to apply appropriate pine surgery to each part of the human body using a treatment device capable of performing point pine surgery. To provide a pine surger which can perform the same treatment and eliminates the danger associated with making the amount of protrusion of a treatment element variable.

[Disclosure of the invention]

Therefore, the present invention provides a pair of treatment elements, a moving means for moving both treatment elements, a width changing means for changing the interval between both treatment elements, and a protrusion ta adjustment means for varying the amount of protrusion of both treatment elements. and a control means for controlling the protrusion amount of the treatment element by operating the protrusion amount adjusting means in conjunction with the movement of the treatment element by the moving means and the width changing operation by the width changing means. By using the moving means, the width changing means, and the protrusion amount adjusting means, it is possible to set the treatment element to the area to be treated in a state where it can be easily accessed, and it is possible to move and adjust the treatment element. When adjusting the width, the amount of protrusion is adjusted in conjunction with the adjustment, thereby preventing movement and width adjustment of the treatment element when the amount of protrusion of the treatment element is increased. The present invention will be described in detail below based on an illustrated embodiment. This pine surge machine is built into the backrest of a chair or into a bed, but in the illustrated example, as shown in Figures 1 and 2, it is built into the backrest of a chair that can be reclined freely. ing.

1.21 is attached by spline connection to both ends of a drive shaft 2 coaxially disposed inside the hollow main shaft 1, and each cylinder 21 is provided with a pinion 23 that meshes with the rack 9. If you rotate the drive shaft 2, it will be 8!
The structure moves up and down along the rail 8 on the back of the backrest 84. As shown in FIGS. 4 and 6, the pair of treatment elements 4, 4 each include an eccentric inner ring 41, an outer ring 43 rotatably attached to the outer periphery of the eccentric inner ring 41 via balls 42, and an outer ring. 4
The eccentric inner ring 41 is attached to the main shaft 1 via an actuating device consisting of an arm 44 fixed to the main shaft 1. It is equipped with an engaging axial groove 41b on its inner circumferential surface and rotates together with the main shaft 1. As is clear from FIG. They are mounted eccentrically by the same amount and inclined in opposite directions with respect to the main shaft 1. The treatment element 4 is attached to a bent end portion of an arm 44 that protrudes tangentially from the outer periphery of the outer ring 43 toward the cover sheet side. It is formed as a roller that is freely rotatably attached to the arm 44 via a bearing 45a. In the figure, 44a is a mounting nut. Also, on the outer circumferential surface of the sleeve portion 41a of the eccentric inner ring 41, a connecting arm 33, a rotating plate 47, and a support roller 4 are provided.
6th grade is arranged. The connecting arm 33 is an eccentric inner ring 41
A cylindrical boss 33a at one end is freely rotatably attached to the outer peripheral surface of the cylindrical shaft 141a, and the outer surface is provided with a pair of protrusions 33b and 33C. The rotating plate 47 is attached to the outer peripheral surface of the boss 33a of the connecting arm 33, and has three bins 47a, 47b, 47d and a hook hole 47c on the outer periphery.
It is freely rotatable relative to the connecting arm 33 only within the m-plate that moves between the pair of protrusions 33b and 33C. A support row 246 made of an elastic material such as rubber and used to prevent the body from sinking is attached to the outer periphery of the cylindrical portion of the rotating plate 47 via a bearing 45b. 48 in the figure is a rotating plate 47
The thrust bearing 41c is a retaining ring which is attached to the tip of the cylindrical shaft portion 41a of the eccentric inner ring 41 to prevent the above-mentioned members from being removed. The outer ring 43 and the rotating plate 47 are configured such that the bin 43a and the hook hole 47c are connected by a tension coil spring C81, and the bin 43a and the bin 47a are connected by a wire 49, so that rotation around the axis is controlled. The two are linked together. Further, the rotating plate 47 is urged to rotate in one direction with respect to the connecting arm 33 by a torsion coil spring C82 whose both ends are locked to the pin 47b of the rotating plate 47 and the slit 33d of the connecting arm 33. The other end of a wire 100, one end of which is connected to a wire drive section to be described next, is connected to a pin 47d that protrudes from the one-turn plate 47. As shown in FIGS. 5 and 7, the wire drive section includes a feed screw 106 installed between both ends of the plate 105,
A slider 108 is screwed onto the feed screw 106 and is prevented from rotating by side pieces 107 protruding from both side edges of the plate 105, and a geared motor M2 that rotates the feed screw 106 and can freely rotate in forward and reverse directions. , the wire 100 that is passed through the outer 101 and guided to one end of the plate 105 is connected to the slider 108.
It is stopped by. The wire 100 is pulled or loosened by moving the slider 108 by rotating the feed screw 106 using the Guinard motor M2. Next, an explanation will be given of the a structure for changing the width (pitch), which is the distance between the positions, of mounting the main shaft 1 of both the treatment elements 4, 4. A retaining plate 80 fixed to the lower part of the gearbox 10 and the motor M
A feed shaft 3 parallel to the main shaft 1 is installed over 0.
This rotationally driven feed shaft 3 has a right-hand thread 31 on one side and a left-hand thread 32 on the other side from the center in the axial direction.
2 respectively. The other end of each connection 7-m 33 is connected to each eccentric inner ring 41 as described above, and since the eccentric inner ring 41 is slidable in the axial direction of the main shaft 1, the feed shaft 3 can be moved in one direction. If it is rotated, the distance between the two connecting arms 33 and the width of the two treatment elements 4, 4 will be widened, and if it is rotated in the opposite direction, the width will be narrowed. The main shaft 1, drive shaft 2, and feed shaft 3 are all rotationally driven by a motor M, and the rotational direction of each shaft is controlled by changing the rotational direction of the motor M itself. However, these three axes are not individually connected to the motor M, and the main shaft 1 and the drive shaft 2 are driven alternatively.
It is configured such that it can be connected to the motor M only when it is connected to the motor M. To explain this power transmission switching mechanism and the reduction mechanism in the gearbox 10, the power transmission switching mechanism consists of the i-star device 5, the two electromagnetic brakes SL, and the vsL2.
, and an electromagnetic clutch SL, J! The output from the I star device 5 is selectively applied to the pair of worm shafts 11, 1 by the operation of one of the pair of electromagnetic brakes SL, SL2.
2. A worm wheel 13 splined to the outer periphery of the cylindrical body 21 meshes with the worm shaft 11, and a worm wheel 14 supported by a shaft 15 meshes with the other ohm shaft 12. The rotation of the worm wheel 13 is transmitted to the drive shaft 2 to cause vertical movement of the mechanism, and the rotation of the worm wheel 14 is transmitted to the elliptical gear 16, which is also supported by the pongee 15, and the elliptical gear 1, which is fixed to the main shaft 1.
6 and a driven elliptical gear 17 that meshes with the main shaft 1 . The planetary device 5 is composed of ball bearings, and includes an inner race 51 as a sun gear and a ball 52 as a planetary gear.
, an outer race 53 as an internal gear, and a retainer 54 as a planet carrier. This collar 56 is integrally provided with a pulley 57 that is connected to a pulley 79 provided on the output shaft of the motor M with a belt 63.
4 is fixed to the worm shaft 11, and the outer race 53 is fixed to the bearing 6.
It is fixed to a cover 59 supported by 1. A pulley 58 is integrally formed at the lower part of a cover 59 that covers a thrust spring 60 that presses the outer race 53 in the thrust direction to apply a preload force to open the outer race 53, the ball 52, and the inner race 51 and the retainer 54. It is connected to a pulley 62 provided on the upper part of the ohmic shaft 12 by a belt 64. Now, if the collar 56 and the inner race 51 are rotated by the motor M with braking applied to the ohmic shaft 11, the ball 52 will only rotate on its own axis because the retainer 54 will prevent the ball 52 from rotating. , rotate the outer race 53. Then, the ohmic shaft 12, that is, the main shaft 1, is rotated via the boot IJ58, the belt 64, and the boot IJ62. Conversely, if braking is applied to the ohm shaft 12, the belt 64
The outer race 53 is locked through the ball 52
rotates on its own axis and revolves, thereby rotating the ohmic shaft 11 and the drive shaft 2 via the retainer 54. The six electromagnetic brakes SL, SL2 operated by electromagnetic plates IfsL, SL2 arranged at each end have the same configuration, and both include a coil 65, a yoke 66, a core 67, a brake shoe 68, and a return spring. 69, which attracts the brake shoe 68 against the return spring 69 by the excitation force obtained by energizing the coil 65, and is slidable in the axial direction by spline connection to the ohmic shafts 11 and 12, respectively. The brake shoes 68 are brought into contact with the core 67 to brake the worm shafts 11 and 12. The feed shaft 3 is driven through the worm shaft 12, the electromagnetic clutch SL5, the worm shaft 34, and the worm wheel 35 provided at one end of the feed shaft 3 and meshing with the worm shaft 34. The electromagnetic clutch S is Phil 70. York 7
1. It is composed of a core 72, a clutch shoe 73, a return spring 74, etc., and the clutch shoe 73 is connected to the lower end of the worm shaft 12 by a spline so that rotational force can be transmitted. Wh n
I↓1 Yamaseimu ^ Bearing 75 on the outer periphery of the lower part of Mushiku 42
The core 72 disposed through the worm transport 34
When the coil 70 is energized, the clutch shear 73 descends against the return spring 74 and contacts the core 72, thereby controlling the rotation of the ohmic shaft 12. This is transmitted through the ohm shaft 34 to rotate the feed pongee 3. 94 is a gearbox in which a two-way sleeve 34 and a two-way wheel 35 are housed, and an electromagnetic clutch S L is installed on the lower surface of the gear box 10.
, and a yoke support stand 93. In this pine surge machine configured as described above, when the main shaft 1 is rotated now, the rotation is regulated by the connection with the rotating plate 47, etc., and the outer ring 43 and the arm 44 protruding from the outer ring 43 are rotated. The attached treatment element 4 performs a three-dimensional movement similar to wobbling due to the eccentricity and inclination of the eccentric inner ring 41. In other words, the amount of protrusion of both the treatment elements 4, 4 towards the cut-sheet side changes periodically, and the interval between the two treatment elements 4 also changes periodically.
The back of the human body leaning against the backrest 84 is massaged by the movement of the massager 4. There are two types of pine surge depending on the direction of rotation of the main wheel 1. There are two cases: the treatment element 4 presses the back of the human body from above to below through the cover sheet, and the other case it moves from below to upward; the former will be considered here for convenience. The latter are called sideburns. When the drive shaft 2 is rotated, the mechanism section moves up and down along the rail 8 within the backrest as described above, so the treatment element 4 is moved to the backrest 84 through the cover sheet.
Touch and move the back of the person who is leaning in the direction along the back muscles to perform a sari pine surge to stretch the back muscles. When the sending pongee 3 is rotated, the pitch of the pair of treatment elements 4.degree. 4 is changed as described above. When the wire drive section is activated and the wire 100 is pulled, the protrusion 33b of the connecting arm 33. The rotating plate 47 rotates within the range in which the bottle 47b is restricted by 33c, but at this time, the rotating plate 47 has a tension coil bone C8.
The outer ring 43 connected by l also rotates. For this,
The treatment element 4 provided at the tip of the arm 44 moves from the position shown by the chain line to the position shown by the solid line in FIG. 5 in accordance with the amount of tension of the wire 100, increasing the amount of protrusion toward the cover sheet side. . The shoulder of the human body leaning against the backrest 84 is moved to a position where it can be pressed from above. Conversely, if you loosen the wire 100, the return spring C8
2, the rotating plate 47 returns, and the rotating plate 47
Since the outer ring 41 connected by the wire 49 returns to its original position, the amount of protrusion of the treatment element 4 toward the cover sheet side is reduced. The amount of protrusion is suitable for pushing the back and waist of the human body from behind. Note that the change in the amount of protrusion of the treatment element 4 due to the amount of eccentricity of the eccentric inner ring 41 is made in addition to the adjustment of the amount of protrusion of the treatment element 4 toward the cover sheet side by this wire drive section. Further, since the rotation of the rotating plate 47 in the direction of increasing the amount of protrusion of the treatment element 4 is transmitted to the outer ring 43 via the tension fill spring C8l, the amount of protrusion increases as shown by the solid line in FIG. Not only when the amount of protrusion shown by the chain line is made small, but also when the amount of protrusion shown by the chain line is made small, the position of the rotating plate 47 (by applying a force against the tension coil spring C81) The amount of protrusion can be reduced.In other words, the strength of the pine surge by the treatment element 4 is
The strength never exceeds the value set by the spring force of the tension coil spring C8. Next, each means for detecting the vertical position of the treatment element 4 along the rail 8, the pitch between both treatment elements 4.4, and the amount of protrusion of the treatment element 4 toward the cover sheet side will be explained. First, there is a means for detecting the vertical position of the treatment element 4 along the rail 8.
As shown in FIGS. 9 and 10, this includes a gear 24 attached to the worm wheel 13 and a gear 2 that meshes with the gear 24.
5. Discs 29 and 30 that are driven to rotate slightly in tandem with the rotation of the drive shaft 2 using the gear 28 connected to the gear 25 via the dog clutch 26 as a reduction gear train, and both discs 29.
It is composed of switches ps, , ps2 that optically detect arcuate holes 29a, 30a formed in 30. In this embodiment, the upper and lower positions to be detected are detected by both switches ps,
Depending on the on/off combination of ps2, there are three points: the upper end yl corresponding to the position of the neck and shoulders, the point y2 corresponding to the back position, and the lower end F3 corresponding to the waist position. As shown in FIGS. 11 and 12, the width detection means for opening the treatment element 4 includes a detection plate 37 provided on one connecting arm 33 parallel to the feed shaft 3, and a pair of detection plates 37 provided on this detection plate 37. 38a, 38b)
In this embodiment, the width position to be detected is set to the minimum width X corresponding to the position of the nape of the neck and the position of the erect column muscles by a combination of on/off of both switches Psi and PS. , the intermediate width x 2 corresponding to the inner position of the shoulder blade, and the maximum width x corresponding to the wide part of the shoulder. Then, the amount of protrusion of the treatment element 4 toward the cover sheet side is detected. This is because there are two factors that change the amount of protrusion.
Each of them is provided with a detection means. First, to deal with the change in the amount of protrusion due to the presence of the eccentric inner ring 41, a permanent magnet 19 attached to the side surface of the disc 18 fixed to the main shaft 1 on the gearbox 10 side and the main shaft 1 on the side surface of the gearbox 10 A pair of magnetically sensitive elements installed in sandwiched positions and turned on in response to the permanent magnet 19, here a reed switch L.
S, -LS2, and a pair of microswitches MS, , MS, which detect the position of the slider 108 in the wire drive unit in response to changes in the amount of protrusion caused by the wire drive unit. are doing. Instructions as to what kind of movement the treatment element 4 should perform are performed using the operating device 6, which is detachably attached to the armrest 83. This operating device 6, which is connected via a cord 7 to the main body control unit and power circuit installed inside the chair, has a three-position switchable mode of ``storage'' and ``operation'' and ``stop'', as shown in Figure 113. Mode switch SW2 and ``neck'', ``shoulder'', ``back'', and

and a light emitting element for displaying operation, L2.

and a control circuit CPU consisting of a signal forming circuit B that creates a pulse code signal according to the operation of each of the switches and sends it to the main body control section, and a signal discrimination circuit B2 that discriminates the sent pulse code signal. We are prepared. The main body control section includes a control circuit CPU of the operating device 6, a signal discrimination circuit C2 that discriminates signals sent from the operating device 6, a signal forming circuit C3 that sends signals to the operating device 6, a timer circuit C4, an operation instruction circuit C3, etc. A control circuit CPU, a motor drive circuit 11 that drives the motor M according to the output of the operation instruction circuit C3, a 7-arm protrusion drive circuit J that drives the motor M2 of the wire drive section, an electromagnetic brake SL, SL, and an electromagnetic brake. clutch SL. , a vertical position detection circuit E consisting of the switches PS, , Psi, a width position detection circuit F consisting of the switches ps, , ps, and a protrusion consisting of reed switches LS, , LSI. The amount detection circuit 01 is composed of a 7-arm protrusion amount detection circuit G' consisting of microswitches MS I-M S 2, and the like. A specific circuit is shown in FIG. Now, the operations performed in response to inputs to the operating device 6 will be explained. When you turn on the power switch SWl, first the rotating plate 4
An operation is performed in which the amount of protrusion of the treatment element 4 due to the rotation of 7 is minimized. This α will be explained in more detail later. Next, when the mode switch SW2 is changed from "storage" or "stop" to "operation", the treatment element 4 starts the sideburning operation at that position. To change this kneading position, it is sufficient to operate the switches SW, -SW. While the input from each switch SW, ~SW continues,
The treatment element 4 moves in the specified direction. However, if the movement limit in each direction is reached, the treatment element 4 stops moving at that time, and resumes the sideburn movement when the hands are removed from the switches SW4 to SW7. Further, the movement range of the treatment element 4 in the vertical direction and in the width direction is narrower than the structural movable range as described below. That is, as shown in FIG. 25, when the width position of the treatment element 4 is between x and x2, the width is from Y+ to y. Although it is possible to move vertically in the entire vertical range up to 2, when it is between 2 and *, it can only move up and down between yI and y2, and furthermore, the treatment can be performed between yl and 12. When there is child 4, the width of treatment child 4 is variable in the range from X to x, but when it is between y2 and y, the width can only be adjusted between X and x2. This is to prevent this from happening. Next, a case where the switch SW is operated will be explained. Now, the switch SW for "stretching your back." When operated, it is first checked whether the width of the treatment element 4 is between Xl and ×2, and if it is located between ×2 and X, the width is adjusted so that it is located at ×2. will be done. Next, after the rotation of the main shaft 1 is controlled so that the amount of protrusion toward the cover sheet side by the eccentric inner ring 41 is maximized, vertical movement by rotating the drive shaft 2 is started, and "back straightening" is performed. Sasurimatsusage is performed. At this time, if the treatment element 4 reaches the vertical direction yII>'+e y s, the direction of vertical movement is automatically reversed by controlling the rotational direction of the motor M. Also, this switch S
If the switches SW, -SW7 are operated while the back lengthening by W3° is being performed, the operations of these switches SW4 - SWt are executed, and manual reversal or width adjustment is performed. When the switch S W 31 specifying "neck" is pressed, the treatment element 4 moves to the position indicated by Xl+y+ and then starts the kneading operation. Switch S to specify “shoulder”
When W32 is pressed, the treatment element 4 moves to the position indicated by X21F+, increases the amount of protrusion by rotating the rotary plate 47 as described later, and then starts kneading operation. Switch SW1 for specifying “back”. When is pressed, the treatment element 4 moves like an insect to the position indicated by Switch S to specify "waist"
When W 34 is pressed, the massager 4 moves to the position indicated by X21y3 and then starts kneading operation. In either case, the position can be adjusted by 3N by operating the switches SW, ~SW! ! and switch sw,,sw
Adjustment of the protrusion amount of the treatment element 4 by operating ,
In other words, it is possible to adjust the strength of the pine surge. When the mode switch SW2 is set to "stop", all operations are stopped at that point, except when the amount of protrusion of the treatment element 4 is large. When the amount of protrusion is large, after this is reduced,
All movements are stopped. When set to "Storage", the treatment child 4
Following the operation to reduce the amount of protrusion of the treatment element 4, the treatment element 4 is moved upward to the 11th position, the width of the treatment element 4 is changed to the maximum width After the amount is set to a minimum, all motion stops. The timer circuit C1 in the control circuit CPU2 performs the same operation as when the count switch SW2 is set to "storage" when the mode switch SW2 is set to "operation". Now, the treatment element 4 is projected by rotating the rotating plate 47 using the wire drive unit! (Arm protrusion amount)
As mentioned above, the switch SW in the operating device 6
This is performed by the operation a = S W *, and this point will be explained in detail. Both switches SW
When s = S W s is operated, the control circuit cpu2 that receives the corresponding signals outputs the output terminals TO, , T02, the motor M2 is caused to rotate in either direction, and the wire 100 is pulled or loosened to adjust the amount of protrusion of the treatment element 4. When the switch SW1 is turned on, the control circuit CPU starts setting the beam, and both output terminals TO, TO2 are brought to L''.
After the motor M2 is prevented from rotating by
1-9 no i horn, 4-Mq's 1 μ force i luxury book individual be If this is H'', move on to the next step to check the state of mode switch SW2,
If the output of , is L'', then the microswitch MS,
The motor M2 is rotated in one direction until the output becomes "H", that is, the amount of protrusion of the treatment element 4 is minimized. Incidentally, this operation may be performed once when the mode switch SW2 is set to "operation". Moreover, when the mode switch SWz is set to "storage", the eccentric inner ring 41 mentioned above
Similarly to minimizing the amount of protrusion caused by the rotary plate 47, the amount of protrusion of the treatment element 4 caused by the rotary plate 47 is also minimized. In any case, the amount of protrusion of the treatment element 4 is made small at the time of starting the pine surge. Then, when the switch SW8 is operated at the time when the mode switch SW2 is set to "operation", that is, at the time when the fir pine surge in any position or the stroke pine surge for straightening the back is being performed, the control is performed in response to the operation of the switch SW8. The circuit CPU2 sets the output terminal TO2 to "H"'
Then, transistors T1 and T4 are turned on to turn on motor M2.
is rotated to cause the wire 100 to be pulled. As a result, the amount of protrusion of the treatment element 4 is increased. Then, when the operation input to the switch SW s disappears or when the output of the microswitch MS2 becomes "H", the motor M2 is stopped and the operation that was being performed until the switch SW8 was turned on is restarted. When the switch SW is operated, the control circuit CPU,
sets the output terminal TO0 to H'', and the transistor T2-
By turning on 73, the motor M is rotated in the opposite direction from the tip, and the amount of protrusion of the treatment element 4 is reduced. Also, when the human power to operate the switch SW is lost or when the output of the microswitch M S + becomes H'', the motor M2 is stopped and the previous operation is resumed.The power switch SW and the switch An operation time chart when operating sw,, sws is shown in Fig. 16. Here, the amount of protrusion of the treatment element 4 can be adjusted steplessly by rotating the rotating plate 47 within the adjustment range. 1111g!i is possible, and changing the amount of protrusion adjusts the strength of the massage element 4's contact with the back of the human body leaning against the backrest 84. This allows you to arbitrarily select the strength of the pine surge according to your preference. Depending on the input from the operating device 6, it is possible to prevent the protrusion amount gq by rotating the rotating plate 47. 17 to 19 show examples of this case.Here, a switch S W :l 2 which specifies the sideburn pine surge for "waste" is used.
The protrusion amount is set to the maximum only when the button is operated, and in other cases the protrusion amount is always set to the minimum. However, the operation of increasing the amount of protrusion of the treatment element 4 when the switch S W = 2 is operated is performed after the treatment element 4 has moved to a position corresponding to the shoulder. That is, to explain the case of the circuit shown in FIG. 19 as an example, when the switch SW 32 is operated, the treatment element 4 is first moved to the upper limit y1 as shown in FIG. That's what I'm trying to get started. That is, after detecting that the treatment element 4 has reached yl, the control circuit CPU2 sets the output terminal TO1 to "H" to operate the relay Ry, and connects its normally open contact to the normally closed switch for maximum protrusion detection. The motor M2 is operated through MS and rotated in one direction until the switch MS is turned off, that is, until the amount of protrusion of the treatment element 4 reaches the maximum. Fig. 23 shows another example of the above processing. This is because the treatment element 4 moves at the upper limit '/ly + insects by operating the switch SW, 2. Until then, the switch SW for fine adjustment of the position of the treatment element 4 is used. ~ When SW7 is repeated, these switches SW4 ~
In addition to performing an operation according to SWt, the kneading operation is started without increasing the amount of protrusion. The kneading motion in the kneading massage is a massager for the shoulders, fl:le:!
-j-L t no -, 4<l! W--4f
i&1? Since only -A, t- is performed, it is possible to cope with the case where it is desired to obtain kneading motion without increasing the amount of protrusion. Now, when massaging the shoulders with the amount of protrusion of the treatment element 4 increased, for example, when operating the switch SW that specifies the downward movement, the amount of protrusion of the treatment element 4 is maximized. The lowering motion of the mama is a motion that applies a large force to the shoulders from above, which is extremely dangerous.
Pine surge caused by this is extremely dangerous. For this reason, in this embodiment, a load detection member is provided to incorporate a safety mechanism that stops the motor M when the load increases, and also to move the treatment element 4 up and down when the amount of protrusion is large. limits the scope. The former uses a switch MS5 attached to a slider 108 in a wire drive unit as a load detection member, as shown in FIG.
When the tension applied to becomes large, the movable plate 121 to which the end of the wire 100 is locked compresses the spring 120 and drives the switch MS5. In order to increase the protrusion amount of the treatment element 4, the load is detected by the tension applied to the wire 100 that pulls the rotating plate 47, and the control circuit CPU2 detects this switch MS5. If it is turned on, the motor M is immediately stopped and the movement of the treatment element 4 is terminated.As is clear from the 70-chart shown in Figure tjIJ27, the latter is caused by the operation of the switch SW, 2. Switch SW5 for treatment element 4 with a large amount.
When the treatment element 4 is moved downward by the operation described above, when the position of the treatment element 4 reaches the 12th point, the lowering operation is interrupted and the movement of the treatment element 4 is limited to the range shown in FIG. 26. Of course, the limit of downward movement is this Y 2! , but it is also possible to provide a detection point other than y, to y, and use that point as the lower limit of movement when the amount of protrusion of the treatment element 4 is large. Among switches SW3, switches sw, , sw, , sw, , sW, 4 specify pine surge other than shoulders.
When is operated or when mode switch SW2 is set to "storage" or "stop", as shown in Fig. 24,
The control circuit CPU immediately sets the output terminal TOv to L'', performs an operation to minimize the amount of protrusion of the treatment element 4, and then performs the above-mentioned operations corresponding to each switch.Control circuit CPU , not only controls the amount of protrusion of the treatment element 4 in conjunction with the movement of the treatment element 4 and the width changing operation, but also limits the movement of the treatment element 4 according to the amount of protrusion of the treatment element 4. [Effects of the Invention] As described above, in the present invention, the treatment child can be placed on the shoulders, neck, back,
It can be moved to any part such as the lower back to perform pine surgery, and at the same time, it is equipped with a protruding tL14v means for the treatment element, so it can perform sufficient pine surgery on the shoulders, as well as the neck, back, and lower back. It is possible to perform appropriate pine surge, and since the protrusion amount adjustment is linked to the movement and width change of both treatment elements, by moving or adjusting the width of the treatment element with a large protrusion amount, It is possible to eliminate the dangers of neck pinching and extremely strong pine surge, and it is highly safe (and from the user's point of view, it can be used without considering the dangers related to the amount of protrusion). It is easy to use.
