Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is housed in the backrest of a chair or a bed, and performs massaging by driving the massaging means, and also allows the movement and width of the massaging means to be changed by the operation position changing means. It's about machines.

Since many of the users of this type of pine surger are elderly, there is a need for one that is particularly easy to operate. Based on this point, it has been proposed that when changing the operating position of the kneading means, for example, if you press the shoulder switch, the kneading means will automatically move to the shoulder position. If the number of selection points for operating positions is increased, the number of switches will inevitably increase. Even more so if a switch is provided for fine adjustment of the operating position.

Ru. On the other hand, it is preferable to be able to operate these switches while resting on the chair or bed.
Connection with the main body] - It is desirable to provide each switch on the operating device that is connected with the cord.1 However, as the number of switches increases as mentioned above, the connecting cord that connects the operating device and the main body becomes larger, making it difficult to operate. was making things worse.

The present invention has been made in view of the above points, and its purpose is to prevent the connection cord from increasing in size even when the number of switches increases due to multifunctionalization and simplification of operation. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is to provide a pine surge machine that can be easily operated at hand. This pine surgery machine is built into the backrest of a chair, and then into a bed, and is used to perform pine surgery on the waist, back, shoulders, and neck of a human body. As shown, it is incorporated into the backrest of a chair that allows the backrest to recline. This chair is equipped with a seat (8a) and an armrest (83) on the lower frame made of pipes.
The frame of the backrest ((6)
), the arm rest is attached to the frame (gas suspension 2/ji (c) between the bottom edge of the frame and the lower frame girth), and the armrest can be attached to the gas suspension by operating the lever (87) provided on the side of the frame. The backrest can be reclined by expanding and contracting, and a pair of rails (8) each having a steel cross section and opposite openings are fixed to the frames (steel) on both sides of the backrest. ) is provided with a headrest (bleached), and support bands (91) are provided in the vertical direction on both sides of the back of the cover sheet (89), which is provided on the front of the backrest (threshold) up to the headrest (goods). In addition, a cushion part 00 is formed on the front surface from the local part of the headrest (881) to both sides of the backrest.Here, the cushion part (91) in the backrest (H) has a width that increases from approximately the center in the vertical direction to the bottom. It is shaped so that the lower back of the human body fits into it, and it not only serves as a cushion, but also supports the back of the human body from both sides.

A rack (9) is provided at each opening edge of the pair of rails (8).
are fixed along the longitudinal direction, and both rails f8+ +
Hinion (23+, which engages rack (9) between 8+,
There is a mechanism part equipped with a pine surge mechanism, and a roller that rolls inside each rail (8). It is self-propelled, and has a main shaft (1) with a pair of kneading wheels +4+14+ attached to the center, and a support frame (40) approximately parallel to the main shaft +11, with a drying box (lO) at one end. As shown in Figs. 8 and 4, a cylindrical body (1) is freely rotatably attached to both ends of the main shaft (1), and a rail is attached to this cylindrical side. (8) A total of four rollers, including rollers (22) that roll inside the rollers (2 rollers are also freely rotatable and rollers (22) are freely rotatable at both ends of the support frame), allow the mechanical section to move along the rails. +8+ +8j.The main shaft (1) is a centrally protruding shaft, and a movable shaft [2) is coaxially inserted into the interior thereof, and the movable shaft 12) has the cylindrical body (21) at both ends. are each attached by two-line connections. Each cylinder side is provided with the hinion (3) that engages with the rack (9). Therefore, when the moving shaft (21) is rotated, the machine m section slides onto the rail (8) and the backrest (the back part of the backrest 84) Perform up and down movement.

A pair of kneading wheels (4) attached to the main shaft +11 are composed of an eccentric inner ring (41) and an outer ring (hook) that is freely rotatably attached to the outer circumference of the eccentric inner ring (1) via a pole. A groove (44) is formed in the inner circumferential surface of the eccentric inner ring in the ring direction, and a groove (44) provided in the axial direction on the outer circumferential surface of the main shaft fl1 is slidably engaged. By combining
The eccentric inner ring (a) 1) rotates together with the main shaft fi+, and the kneading ring (4) is slidable in the axial direction of the main shaft +11.

When the main shaft (1) is rotated, at least the eccentric inner ring (41) of the massaging ring (4) rotates, and each eccentric inner ring (41) in the pair of massaging wheels 14) is rotated by the same amount in the same direction. They are mounted eccentrically by 1, and inclined in opposite directions with respect to the main shaft (1). Therefore, the rotation of the main shaft (1) causes the main shaft (
Not only does the amount of protrusion from 1) change periodically, but also the distance between the two kneading wheels i4+14) on the side of the cover sheet changes periodically. The rotation of the massage wheel 141f4) by the main shaft (1) massages the back of the human body leaning against the backrest through the cover sea)+89)'e. By the way, there are two types of pine surge depending on the rotation direction of the massaging wheel 14). That is, when the portions of both kneading wheels +41+41 that protrude by a large amount from the main shaft (1) move while pressing the back of the human body from above to below via the cover sheet (89) (kneading). There are two types of sideburns: 1) and 2) cases in which the sideburns move from downwards to upwards (sideburns).

This point will be touched upon again when explaining the operation.

Next, a mechanism for changing the width (pitch) between both kneading wheels 1+iIn will be explained. It spans the upper part of the flat box (1o) and the holding plate fixed to Tanabata M, and the main shaft (1o)
) is installed parallel to the feed shaft (3). This feed shaft (3), which is rotationally driven, has a right-handed threaded portion l on one side from the center in the axial direction.
311, the other is the left-hand threaded part ct2, and the double-threaded part 01)
One end of the connecting arm (Harane) is screwed into each of the six arms.

The other end of both connecting arms is connected to the eccentric inner ring t41) of each kneading wheel (4), and the eccentric inner ring (41) is slidable in the axial direction of the main shaft fl as described above. If the feed shaft (3) is rotated in one direction, the distance between the connecting arms and the pitch between the two massage wheels (4) will be widened, and if the feed shaft (3) is rotated in the opposite direction, the distance will be narrowed. However, in this embodiment, when the feed shaft (3) rotates, the main shaft +
1) is always rotating, so the connection arm (g) and the eccentric inner ring ←l) of the 1st massaging ring (4) are connected through a thrust bearing so that they can freely rotate. That is, as shown in FIG. 4, an extension tube (41a) is provided on the inner surface of the eccentric inner ring, and an inner flange at the end of the connecting arm is attached to the outer periphery of the inner flange.
A thrust bearing is formed by arranging a ball cage η held by a retainer (4) between the opposing faces of the inner flange and the inner flange, and the eccentric inner ring (4υ and the connecting arm It is designed to be able to freely rotate.Here, both connecting arms (B3
) is placed between the pair of kneading wheels 141141, and the lace plate (
A thrust spring 49), which is a compression coil spring, is provided between the retaining ring Q50) which is fixed to the end of the extension cylinder part (41a) of the eccentric inner ring ←1) and the thrust spring 149), and this thrust spring 149) is used to massage the thrust bearing. Press and urge the ring +4)&'j,
Connecting arm (33) for narrowing the width between the massage wheels (4)
) movement is caused by massaging wheel (4) via 1 thrust spring ■)
The reason for this is as follows. In other words, when the feed shaft (3) is fully rotated to narrow the pitch between the two kneading wheels +4]+41, or when the kneading wheel (4) is driven at full rotation with the bottom of the shaft being narrow,
In areas where a large pinching force is applied, such as the nape of the neck, both kneading wheels + 4) 14) move in the axial direction, where the pitch becomes wider, against the thrust spring 9), improving safety and improving flexibility. In addition, at the same time, the backlash of the thrust bearing is suppressed by the thrust spring 9).

As is clear from the above, this pine! There are eight rotationally driven axes in the r-gear machine: the main shaft (1), the moving shaft (2), and the feed shaft (3), but all of these are driven by a single shaft M that can be rotated forward or backward. be done. The main shaft fi+ and the moving shaft (2) can be driven alternatively, and the feed shaft (3) can be driven to the -ta M only when the main shaft +11 is connected to the t-ta M. It is configured so that it can be connected. To explain this power switching mechanism and the deceleration mechanism in the flat box (io), the power switching mechanism consists of the planetary device (5) and the
Two electromagnetic players SL+, SLg, and electromagnetic clutch SL! The output from the planetary device 15) is alternatively transmitted to a pair of worm shafts (rivers 12).

A worm wheel (13) connected to the splice is engaged with the outer periphery of one ohm shaft (the cylindrical section 1), and a worm wheel 04) supported by the shaft 0 is engaged with the other worm shaft 02). do. The rotation of the ohm wheel (13) is caused by the movement axis 12), and the rotation of the other ohm wheel 04) is caused by the rotation of the ellipsoid A, which is also supported by the shaft (I[i), and which is fixed to the main axis f1+. It is transmitted to the main shaft +11 by the driven elliptical shell A θη meshing with the oval shell A 4 .

In the illustrated example, the planetary bag @ (6) is configured with a ball bearing to reduce the size and operation noise. That is, the sun gear is made up of an inner race 1), a planet a is made up of a ball 1521, an internal gear metal remover is made up of a retainer, and the planetary ceria is made up of a retainer. An inner race φυ is fixed to the outer periphery of the collar ((E)) attached to the free-rotating self-pressure.This collar is provided on the output shaft of the t-ta M and is connected to the It is integrally provided to the pulley value connected to it.The retainer diagram also has an ohmic axis (o)il.

The outer race brass is fixed to the cover (
59). A thrust spring (61 or retainer) that suppresses the outer race state in the thrust direction and applies a thrust preload force between the thrust spring, the ball state, and the inner race βυ
A pulley link is integrally formed on the upper part of the cover which covers the worm shaft.
Connected by Shu. Now, with braking applied to the worm shaft (11), the collar (Rin and inner race iI) is adjusted by ℃-ta M.
When the ball is rotated, the retainer prevents the ball from rotating, and the ball only rotates on its own axis, causing the outer race to rotate fully. Then, the worm shaft (1'4) rotates through the pulley, belt (incorporated), and the center shaft.On the other hand, if braking is applied to the worm shaft H, the outer race link is connected through the belt t61. Since the ball r1 is locked, the ball r1 rotates on its axis and revolves, thereby rotating the worm shaft (+1) via the retainer.

Braking is applied to the ohm shaft (12 (11)) opposite to the worm shaft (11) (12) from which you want to extract the output, but this damping is applied to the end of each worm shaft (11) (l). This is done using the electromagnetic pulleys SL+ and SLt.At the upper end of the worm shaft (11), the electromagnetic player SL+ is connected to the worm shaft (11). Both electromagnetic plates +
SLt and SLi have the same configuration, and both have a coil (e
4. York (@, Cocoa 67), Shuu Cormorant during play,
The return spring is composed of a spring, and the excitation force obtained by energizing the coil attracts the player shoe against the spring, and the spring line is connected to the worm shaft (II) and H, respectively. Player shoes (6) that are slidable in the axial direction
The worm shaft 01) (12) is brought into contact with the barrel core 17).
) The remaining feed shaft (3) is driven through the worm shaft (12) and the electromagnetic clutch S. A worm shaft is coaxially provided directly above the worm shaft 02), and a worm wheel provided at one end of the feed shaft (3) meshes with the worm shaft. These worm shafts and ohm wheels are housed in a yoke support (9!) on a yoke support (9!).
It is attached to the top surface of s. The electromagnetic clutch SLm is
It consists of 4 coils, 4 yokes, 4 cocoas, a clutch shoe, a return spring (b), etc. The clutch shoe (7) is connected to the upper end of the ohm shaft 0'4 to generate rotational force. The coil (71 If energized, the clutch shoe (73
) moves upward against the return spring e741 and comes into contact with A4, and the rotation of the worm shaft 02) is stopped.
It is transmitted to the worm shaft through the core U'Nc, and the feed shaft (3)
It rotates.

By the way, as will be described later, this pine surge machine automatically adjusts the upper and lower positions of both kneading wheels (4) overflowing to the grooves (8) and the both kneading wheels 14 in response to input from the operating device (6). ) and the rotational position of the massaging wheel (4). The means for detecting each movement for this purpose will be described. First, the vertical position of both massage wheels (4) relative to the rail (8) is as shown in Figures 5, 7, and 8.
Rotation of the disk - and two photoelectric switches PS+,
Detected by Psi. Both discs rotate together with the rotation of the moving shaft (2), and rotate no more than one revolution within the range of movement of the moving shaft (2) sliding on the rail (8). The reduction ratio from the moving shaft (2) is determined as shown in FIG. dog clutch (company)
The speed A (c) connected through the f is used as a reduction gear train, and the first disc c29+ is meshed with the f a (c). The reason why the dog clutch f281 is interposed is for convenience when assembling, and when the mechanism part is set at the top of the backrest, the dog clutch (c) can be removed and the dog clutch (c) can be removed. 1
Both discs 4- are rotated so that the uppermost end detection signal is output by the disc holder, the second disc 4, and the switches PS+ and Psi, and the dog clutch holder is engaged by the biasing force of the spring (271). ◇In the wooden example, the upper and lower positions of the mechanical parts to be detected are determined by the upper end YI% corresponding to the neck and shoulder positions.
The lower end y3 corresponding to the waist position and the point yx corresponding to the back position are 8 points, and 71 points and 72 points are placed on the first disk).
A circular arc hole (
29a), and the second disc is provided with an arcuate hole (80a) having a center angle approximately equal to the value obtained by subtracting the rotation angle of the second disc corresponding to the movement between the upper and lower ends of the mechanism section from 860°. It is provided so that one end overlaps the circular arc hole (Ha). Switch PS+ has arc hole (g9a) t, switch PS* u has arc hole (8
0a) In order to detect f, (14) the light emitting element and the light receiving element of both the photoelectric type switches ps and psi are arranged to straddle the ends of the first disc and the second disc, respectively. The light emitting element receives the light emitted by the light receiving element through the circular arc hole (2
9a) (80a), the mechanical section is at the 71st point when both switches PS+ and PSg are on, and when only the switch PSx is on, the mechanical section is at the 71st and 72nd points. During this period, when the switch PS+ is turned from on to off, or from off to on, the mechanism section is set to 7.
If both switches PS+ and PS* are off, it is detected that there is a mechanical part between point 72 and Yl#, and when only switch PSz is on, it is detected that there is a mechanism at point 72.

The width between the kneading wheels (4) can be detected by attaching one end of the detection plate 1B71 parallel to the feed shaft (3) to one of the connecting arms (to) as shown in Fig. 9 and Fig. 1θ.・Six (

11 (88a) (38b)
\Switch PS4 is designed to detect the long hole (88b). Regarding this width, the minimum width XI corresponds to the position of the neck muscles and columnar erector muscles, and the intermediate width X corresponds to the inner position of the shoulder blade! 8 points of the maximum width XI corresponding to the widest part of the debris are detected, and when the switch PSs is turned off at one end of the elongated hole (88a) when the switch Ps4 is turned on, 11 points are detected, and both switches PSI and PS4 are detected. If both are on, x is the time between points xl and Xs, when switch PSs is on and switch PS4 is from on to off or from off to on.
s point, if only switch Psi is on, 11 points and Xs

is off, it is detected that both kneading wheels 14114) are present at each of the x3 points. FIG. 12 shows the relationship between the on/off states of the switches PSs to PS4 and the vertical position and pitch of the massaging wheel (4).

Then, for the reason described later, the disk-shaped subbox (10) is used to detect the amount of protrusion toward the cover sheet (■) that varies depending on the rotational position of the kneading wheel (4) for reasons described later. Attach a magnet to the side surface and
As shown in FIG. 8, a pair of reed switches LSI, LS*k, which are turned on in response to a magnet Q@, are mounted at positions sandwiched between the main shaft 1111 on the side surface of the early box (10). Here, when the reed switch LS1 is turned on facing the magnet wire of the disc α~ rotating together with the massaging wheel (4), the massaging wheel (4) is turned on so that the amount of protrusion into the cover sheets (m pieces) is maximum. , when the reed switch LS2 is turned on, the amount of protrusion is made to be the minimum.In addition, in place of the switch PSI-PS4, which is a non-contact type switch, and the reed switches LSI and LS2, a 3' site switch is used. Of course, a contact type switch such as the one described above may also be used.

The selection operation of the operation in the pine surge machine configured as described above is performed by the operation device (831) which is removably attached to the armrest (831).

Light emitting elements L arranged corresponding to the sides of the W opening, respectively.
At the same time, s l-L m a corresponds to each corresponding position of the schematic diagram of the human body provided on the surface of the operating device (6). In other words, the light emitting element L3 is placed at the neck position in the schematic diagram, and the switch SWm for specifying the "neck" is placed on this side.
The push buttons of the switches S"Na and SWi are triangular or inverted triangular so that the retracting direction can also be determined from the shape of the push button. For SWy, “wide<”
Arrows corresponding to "narrow" are displayed to make it easier to distinguish.

If the controller (6) with a large number of switches were to be detachable from all chairs, if each switch was connected to the main body control section with an independent signal line, the number of signal lines would be extremely large and the connection cord would be required. Therefore, as shown in Fig. 14 and Fig. 1b, an operating device (6) is used as shown in Fig. 14 and Fig. 1b.
A control circuit CPU1, such as an L-chip microcomputer, is installed inside the main body control section and inside the main body control section, respectively. Data signals are sent and received using pulse codes between the two, and only two power lines to the controller (6) and eight signal lines for sending and receiving data signals are used. In other words, the controller (6) can be held at hand by connecting the main body control section and the power supply circuit to the controller (6) using a 4-core curl-type connection cord (7), and the connection cord m is thin. In addition, in addition to the fact that a curl type is often used, the operability of the operating device (6) is improved. Psi,

In accordance with the data transmission instruction signal created and transmitted by the PU2 in its signal forming circuit C3, the control circuit C of the operating device (6)
In the PU, the operated SW! .about.SWt, a separate pal code data signal consisting of, for example, 4-hit pulses is created in the signal forming circuit ΔB1, and this is repeated several times with a pause period in between, and then transmitted to the control circuit CPU2 of the main body control section. Then, in the control circuit CPU5, in order to have noise elimination ability when receiving this data signal, the signal discrimination circuit f

Sends an output signal to the circuit HXI, and repeats a reception confirmation data signal to the control circuit CPU+ and, if necessary, a lighting instruction signal for the light emitting element L2 indicating preparation, until the kneading wheel (4) reaches the designated state. and send.

Then, the control circuit CPUI links this lighting instruction signal multiple times in the signal discrimination circuit B2, and if they match, the light emitting elements Lx and Lso=
A lighting instruction signal of L s a is output to the light emitting element drive circuit A. However, the switches SW4 to SWt transmit pulse code data signals during their ON period, and cause the control unit 1Mr CPU to execute operations only during the reception period.

Next, the operations performed in response to inputs to the operating device (6) will be explained. When the power switch SW+ is turned on, the light emitting element Ll
only lights up. At this time, if the switch SW is in the "stop" position, it will not operate at all, and even if it is in the "storage" position and the massage wheel (4) is in the storage position, it will not operate at all. However, if the switch SW3 is in the "lIJ work" position, the electromagnetic plater SLt applies braking to the worm shaft (■), and the rotor M, which rotates clockwise, rotates only the main shaft fl), and the massaging wheel 14) The worm shaft θ is in the position when the fc power switch SWs is turned on, and the kneading wheel (4) is in the retracted position when it is driven through the main shaft (1) to perform the heaving operation. ) is at the upper end, has the maximum width, and has the smallest amount of protrusion, and when the power switch SW+ is turned on, the kneading wheel (4) is not in this storage position and the switch SWi is in the "storage" position. If in position,
After using this pine surge machine, switch SWi 1k
0, which performs all the same operations as when switching from "operation" to "storage", that is, in the control circuit CPU5, the operation device (6)
Sends a lighting instruction signal to the control circuit CPU5 of the light emitting element L2 to indicate that the light emitting element L2 is in preparation, and makes the light emitting element Ll blink. Move the massage wheel (4) up to the uppermost point y1, and when it reaches 11 points, the temperature will change to ℃-
While rotating the motor counterclockwise, operate the electromagnetic slider SLs and the electromagnetic clutch SLv so that the width of the kneading wheel (4) becomes the maximum width Xs.1 After that, the electromagnetic clutch SLs
Separate the chisel and rotate the kneading wheel (4) at the xs + Yt position. During this one rotation, when the magnet (I special) and the reed switch I, Ss are turned on, the massaging wheel (4
) when the amount of protrusion becomes the minimum, the full load and the light emitting element L
Turn off v. Light emitting element Li.

When ~Lea is lit, these are also turned off.

If the kneading wheel (4) is in this storage position, a person who sits vigorously on the chair will not be able to slam his or her body against the kneading wheel (4).

Now, to perform kneading pine surge at an arbitrary position, switch SW* k r is operated. As a result, the massaging wheel (4) starts rotating at that position and performs the massaging operation as described above, but in order to change this position, the switches SW4 to SW7'FC are selected and operated.

During the period when the switch SW<' is turned on, the t-tater M turns to the left and only the electromagnetic player SL operates, and the rotation of the moving shaft +21 moves the kneading wheel (4) upward. If the switch SWs is turned on, move the kneading wheel 14) downward,
When the switch SVh is turned on, the electromagnetic plate t'' is rotated counterclockwise to t-tM' only during the turning-on period.
Both kneading wheels are operated by activating SL+ and electromagnetic clutch SLs]
4) Make the pitch wider. Also switch SW7
If so, turn the heptad M clockwise to narrow the width of the kneading wheel (4). These switches SW4~SW
During the input period of t, the light emitting element L! It blinks to show that it is moving. And these switches SW
4 ~ If you release the money from SWγ, the massage wheel (
The sideburning operation according to 4) is restarted.

However, in the above-mentioned movement operation, the operation by turning on the switch SWs and the switch SW@ differs depending on the initial position of the kneading wheel (4). That is, in this embodiment, an operation prohibited area S2 is provided as a diagram in the control circuit CPU5 within the range in which the kneading wheel (4) can move, and the kneading wheel (4) is controlled by the switches S Ws and S Wa. This is because there is a risk that the movement of step 4) will enter this movement prohibited area Sz. No movement area S! This is the area indicated by diagonal lines in FIGS. 12 and 18, and is the area surrounded by the % yl yx point and the Xs Ws point.

If the kneading wheel (4) performs kneading motion in this area, there is a risk of pinching the lower back or ribs. At the same time as eliminating this danger, it is possible to perform a wide range of pine surges in the waste area 1. In order to be able to store the kneading wheel (4), the lower part of both sides of the movable range of the kneading wheel (14) The operation prohibited area Ss'ii is separated from the operation area 5ti in a T-shape. In addition, X in Figure 12
The area between 1 and 1 is also a movement prohibited area S1 due to the slope of both massage wheels 14)+4) and the fact that the massage wheels (4) do not directly hit the spine. And movement prohibited area S! Due to the presence of , the movement area Sr is also divided into an area inside the X1 point where the kneading ring (4) moves freely up and down from the neck and shoulders to the waist, and an area outside the Xs point. downward movement is restricted,
'1 is substantially divided into two areas, one for storing the kneading wheels (4), and the other for storing the kneading wheels (4). The operating area S1 thus set is also a range that sufficiently covers the location of the "ribo" located on the back of the human body. In addition, as mentioned at the beginning, the reason why the shape of the backrest of the chair (cushion part 01 at the threshold) is made wider at the bottom is because of the movement prohibited area S.
! This is by arranging the seat so as to surround the operating area S+'j-, in response to Furthermore, in terms of design, it is designed to visually convey that a wide range of pine surges can be performed on the shoulder area. Now, like this, movement prohibited area 8
Since it is located below the upper part of both sides of the 3''t-operation area Ss, the kneading wheel (4) can be moved downward in the following two ways.When the kneading wheel (4) is moved downward by the switch SWs, When the initial position of the kneading wheel (4) is directly above this operation prohibited area S2, the switch S is turned on as shown in section A in FIG.
According to the input of Ws, first move the kneading wheel i4+'f: downward,
When the kneading wheel (4) has descended to point 13, an input from the vertical position detection circuit E causes the instruction circuit C1 to temporarily stop the downward movement of the kneading wheel (4) and move the kneading wheel (4) until it reaches point X2. 4) The width between the two is narrowed, and then the massaging wheel (4) is all lowered again.It passes along the route R1 in Fig. 12.The initial position of the massaging wheel (4) is between the points X1 If so, it will move straight down as shown in route R3.In this way, as shown in rule R1, when it is necessary to move forward and narrow the width, it will first move downward until it reaches point X2. The reason for this is that whether or not the downward movement passes through the ys point depends on the operation of the user who operates the switch SWa. Even though it only causes
This is because it will take the route Rsk as shown in Figure 2, and considering the function of the planetary device fil, that is, the inability to move up and down and change the pitch at the same time, 1. It is designed to move in the shortest distance. A certain 0 and a massage wheel (4)
If the initial position of is above 71 points, the kneading wheel 14) can be moved to widen the width to x3 by turning on the switch SWa, but if it is below 73 points, the kneading wheel 14) can be moved at the x2 point.
stop moving. In any case, if switches SW4 to SWy continue to be turned on even after the massager (4) reaches its travel limit, the entire load is stopped and the user is notified that the travel limit has been reached. , switch SW4~SW again? The sideburn operation is restarted as soon as the hand is released from the button.Next, we will explain the function of the switch SWi.
1. Massage ring 14i'? This is an operation in which the outer ring of the kneading wheel (4) is moved up and down without being rotated, and the outer ring of the kneading wheel (4) is dipped in the spine and rolled.If the switch SWz is set to "operation" and the switch 5Wso' (i7 is turned on), By transmitting and receiving data signals, the control circuit CPU2 first performs a preparatory operation, and also causes the light emitting element LIO of the operating device (6) to light up and the light emitting element L2 to blink.This preparatory operation means that the massaging wheel (4) When it is between point X1 and XI, there is a massage wheel (
4) When the width between the grinding wheels (4) is narrowed and moved to the X1 point, or when the grinding wheel (4) is moved to the X1 point, or from the initial
When there is a massaging wheel (4) between the point and XI, the massaging wheel (4)
) Reed switch L during this one rotation after full rotation
When S+ is turned on, the light emitting element Lsf is turned off and the kneading wheel] 4) is started to move upward. The upward movement is started while the protrusion amount of the kneading wheel (4) is maintained at the maximum.

When the 71st point is reached, the direction of rotation of the C-tar M is reversed and moved downward by the input from the vertical position detection circuit E. When it reaches the lower Qya point, it moves upward. It automatically flips over at the top and bottom ends and continues its entire operation. Also this switch 5WI
(If the switches SW4 to SW7 are turned on during the operation in step 1, the operations by these switches SW4 to SW7 are executed interrupting the above-mentioned back straightening operation. However, the light emitting elements I and 3o remain lit. In other words, if switch SW4 is pressed while the kneading wheel (4) is in the lower position, the kneading wheel (4) is turned off as shown in section 00 in FIG.
If the switch SWs is pressed during the upward movement, 0 manual reversal can be performed at which point the movement changes to the downward position. Also switch SWs, SW? If is pressed,
The operation is changed to widening or narrowing the width between the kneading wheels 14)' (only between the l-13 point and the X1 point) 1 After this, the protrusion amount is set and the original operation is resumed. 0
The light emitting element L22 blinks while both switches SWs and SWy are being pressed and while the protrusion amount is being set.

Furthermore, 'f1. Even if the massaging wheel (4) reaches the position ys, if the switches SW4 and SWs, which designate the movement beyond these limit points, are pressed, the Tanabata M
In addition, if the switches SWa and SWy are still pressed even after reaching the limit point of Xi and After setting the protrusion amount, the rotation reversal operation is resumed.

When switch 5Wili is turned on, light emitting element 1. The light emitting element flashes as the ms lights up, and the kneading wheel i4)'t
Move it up to the yt point, and then determine the spacing between the kneading wheels (4) until it reaches the X1 point. And the massage wheel (4) is X1l)
”If the switches SW4 to SWt are turned on after the 0 switch 5Ws1, which turns off the light emitting element L2 and starts kneading when the point is reached, the switch SW4 to SWt is turned on, it will turn off the light emitting element L2 and start kneading. When the light emitting element L2 flashes, the sideburns are stopped and the width between the massaging wheels (4) is changed, and the switches SW4 to SW are turned on.
7 is released, the kneading by rotating the kneading wheel (4) is resumed at the position moved by these while the light emitting element Lslf remains lit. When the switch SW■ is turned on, the light emitting element Lit is turned on, and the light emitting element L2 is made to blink. Then, after adjusting the width, when the kneading wheel 14) reaches the point Xs y>, one light-emitting element is turned off and the kneading operation is started at this time. Furthermore, when the switch 5Wssf is turned on, the light emitting element Lss lights up, and the light emitting element L1 blinks, and after the following operation, kneading in the "back" position starts. When the position of the kneading wheel 14) is above the 'lx point, that is, when the switch PSs is on, the rotation of the kneading wheel 14) is first rotated in the same direction as the rotation direction up to that point, as shown by the section 0 in Fig. 16. When the reed switch LS is turned on during this one rotation, the kneading wheel (4) is moved downward with a reduced amount of protrusion. If you want to move the kneading wheel i4+1, which had been doing all the kneading movements on your shoulders and neck until then, to the lower tl+, switch S.
If it is a downward movement due to Ws, the downward movement will stop as soon as you release your hand from the switch SWi, but during the period of movement to the specified position using the switch 5Wss or the switch SW opening, the downward movement depends on the user's will. Although the downward movement is stopped when the switches SW4 to SWv are turned on as will be described later, the amount of protrusion of the massaging wheel (4) remains large and the downward movement is stopped when both switches 5Wsi to 5Wa-a are turned on. If the lower back i is performed, there is a risk that the kneading ring (4) will put strong pressure on the shoulders etc. from above. To eliminate this risk, first reduce the amount of protrusion and then move it downward. Now, when you reach the y point with this downward movement, the massage wheel (4
) is at a position wider than the x3 point, the pitch of the massage wheel (4) is narrowed so that it comes to the x2 point, and after that, the sideburns are started. However, if the pitch of the kneading wheel (4) is between the x1 point and x2 from the beginning, the kneading wheel (4) starts rolling up when it reaches the 12th point at its lower cut. Furthermore, the initial position is y! If it is below the point, there is x at this time, and there is a kneading wheel 14) between the point and the point, so keep moving up and down until you reach the 18th point. Then start raising sideburns immediately.

When the switch 5Wc4 is turned on, the light-emitting element L14 lights up, and the light-emitting element Lx blinks, and the massage wheel (4)
x1 point and x! 4) First move the kneading wheel so that it is located at point 13 between the points. At this time, the downward movement is performed using the massaging wheel (4) in the same way as when the switch 5Wss (j) was turned on.
This is done after reducing the amount of protrusion of
The process is continued until reaching 18 points via the routes R+ and Rz'i of the degree 0. Thereafter, the kneading wheel 14) is made to perform a massage operation. In addition, these switches SWs+ -5
Once W84 is turned on and the specified position is being kneaded or kneaded, switch SW4~
If SW7 is turned on, this specified operation will cause the light emitting element Lm+~
Ls+f is turned on and 7' is interrupted and executed, and when this specified operation is performed even after reaching the travel limit, or when two or more switches SW4 to SWy are turned on at the same time, the entire load is turned off and switch SW4 is turned off. ~After waiting for SW7 to turn off, the operation of raising or lowering the sideburns is resumed at the position after the movement.

As is clear from the above explanation, switches 5Wjt to S
Do not perform manual positioning by turning on either the W-ring or SW port (the kneading ring (4) will automatically move to one of the four locations on the neck, shoulders, back, and waist). It starts kneading motion, fully automatically sets the width, and starts straightening the spine, and if the automatically set location is out of alignment with the desired position for pine surge, manual movement is performed. Switch SW4~SW for
Since the specified operation No. 7 is interrupted and executed, and the kneading operation or back straightening operation is restarted at the moved position, the operation can be performed at the desired position. Moreover, although it was not mentioned in the above operation explanation, the switch S
While moving to the designated location due to the introduction of Ws o NSW Ws 4, the Rimari light emitting element L! While flashing, press switch SW.
When 4 to SW7 are operated I7, the output for moving to the above specified location is set to 10 cents in the operation instruction circuit C+, and the specified operation of the switch 5Wso=SW port is started at the position at that point. In addition, when there is a place where you need pine surge while moving to a designated place, you can immediately move to pine surge, so the operability is extremely good.

By the way, there are two types of kneading motions: raising sideburns and lowering the sideburns.1 Also, when the kneading motion is performed at a designated location by turning on the switches 5Wil to 5W14, the output from the control circuit CPU5 causes the shoulders to be kneaded and the sideburns to be rolled up at other designated locations. As already mentioned, this is because raising the sideburns is more effective for the neck, back, and lower back, while lowering the sideburns is more effective for the shoulders. By not providing a switch, the pine surge effect can be improved simply by specifying the kneading location, while avoiding the complications associated with an increase in the number of switches and switches.

In addition, in conjunction with this, after setting switch SW to "operation", switch SW4 to SW without operating switch SWs.
When the kneading operation is performed at a desired location by the operation of y, the light emitting element Ll is turned on rather than blinking in response to a command from the control circuit CPU5 to prompt the operation of the switch SWi. This is because when massaging the shoulders, even though lowering the sideburns is effective, in cases such as the above, only the sideburns are performed as described above, and it is not possible to do it automatically by operating the switch SWs'i. This is because it is preferable to use the switch SWm to perform massage at an arbitrary position, since the position of the massage wheel 14) can be adjusted when the massage is done. Further, a buzzer or the like may be used as a display prompting the operation of the switch SWs, but if the light emitting element L2 is also used for displaying the preparation status, the display will not be complicated and the cost will be low. In addition to turning on the light to distinguish the blinking during preparation, the blinking speed may be changed.

When the timer circuit C4 in the control circuit CPU x shown in FIG.
Or, if the switch SWs is "operating", the power switch SW
Approximately 15 minutes after turning on the +, switch SVh is turned on.
The same data signal as when "storage" is sent to the operation instruction circuit CI.
K output, and even after this time has passed, the switch SW! When the kneading wheel (4) is in the "operation" position, the massaging wheel (4) starts to be retracted. This is done in consideration of the situation where the user falls asleep while receiving pine surge while sitting in a chair, and is intended to eliminate the effects of excessive pine surge. However, if the user wants to receive the pine surge continuously, it can be reset by operating the switches SW1 to SW7. If you want to finish the pine surge, just switch SWs f from "storage" to "stop". When "storage" is selected, the massaging wheel (4) is moved to the storage position as described above, and then the entire load is turned off. "Stop" and next time the entire load will be turned off at that point. After operating one of the switches SW8,
If the switch 5Wsf needs to be changed, the switch SWz may be set to "storage" or "stop" once, and then switched to "operation" again. As is clear from these descriptions, the control circuit CPU5 recognizes each operation of the operation switch groups SWz to SWt as switch SW2, switch 5Ws (switch SWs o
-S Ws 4 is the same rank), and switches SW4 to SWt are placed in the same order, especially switch SW3 and switch S
Although the operation caused by the operation of W4 to SWt is executed with an interrupt, the contents of switch SWs are not the same as switches SW4 to SWy.
1 switch sw4 related to movement to a specified location during the preparation operation of switch SWs.
~Except for the pupil by SWy.

Next is the control circuit CPU! The full load due to the output from the t-ta MX electromagnetic plate +SLt, SL2, and the operation tie three of the electromagnetic clutch SLs will be explained. FIG. 16 shows the operating ties for these full loads, and V in the figure is the light emitting element L! The period in which t flashes is the period in which the kneading motion or back straightening motion is performed. As is clear from the figure, when the heptad M starts rotating, it is delayed by a time α from the time when the switch for this purpose is operated. In addition, the on operation of the electromagnetic players SL+, SLt and the electromagnetic clutch SLs is also delayed by the time β, and furthermore, when one of the electromagnetic players SLl, SL is turned from on to off and the other from off to on, both of them are In order to prevent overload from being turned on and overloading the 7-meter M, a short time γ is provided during which both are turned off, and γ, α, β
It is said that The electromagnetic plate 1", which starts rotating smoothly in either direction, prevents overload from being applied to the motor M, and turns on at the same time as the direction of rotation changes, is used when sL+ and SLz change. This is so that the inertial rotation of the heptad M in the direction of rotation is rapidly stopped by continuing the connection with the load for a while.Furthermore, as mentioned above, when the entire load is turned off, , especially by operating switches SW4 to SWt.
4) Even if the movement limit is reached, swi1'J''fsWa
~SW? When operation continues and the entire load is turned off,
Because the planetary device (6) is used, if the heptad M is left unloaded, its operation will become unstable and there is a risk that the mechanical movement limit will be overrun by the inertial rotation of the hepta M. , when this full load is turned off, the main shaft +11 e 'E is a load that does not pose a risk of overrun.
The electromagnetic plater SL+k for connecting to -5M is turned on for a short period of time δ or kept turned on to absorb the inertial rotation of the t-tater M by kneading operation. This time δ
It only takes a short time of less than 1 second, and the power consumption to completely prevent overrun is very small. The kneading means can be moved to specified positions such as the neck, waist, etc., and the kneading means can be easily moved to the desired area, and these switches are connected to the main body with a connecting cord. Not only is it easy to operate it by hand because it is a β on the device, but it also has a control port @'fc that sends and receives pulse code data signals to the main body and the controller, making it multi-functional and simplifying the operation. The figure shows a case where the number of switches increases due to the

In this case, the connection cord does not become large, and the operability of the operating device is good in this respect as well.
