4 is in contact with the upper surface of each plunger 26, 26.

Reference numeral 27 represents a return spring disposed within the hollow shaft portions 25, 25.

The rotation of the pulley shaft 16 driven by the motor M rotates both the clutch plates 20 and 21 via the spur gear 17.
Since the worm shafts 8 and 19 are loosely fitted, the worm shafts 18 and 19 are not rotated.

Now, solenoid SL1. When SL2 is energized, the plungers 26 and 26 move upward to push up the movable clutch plates 22 and 23 that are slidable on the worm shafts 18 and 19, and the clutch plates 20 and 22, and the clutch plate 21 and the movable clutch. The plates 23 are connected to each other.

The rotation of the pulley shaft 16 is caused by the spur gear 17 to each clutch plate 2.

A pair of tilted eccentric kneading wheels 37, 37 are attached to the drive shaft 34.

This kneading ring 37 consists of an inner ring 38 and an outer ring 39.
An inner ring 38 is fixed to the drive shaft 34 in an eccentric and inclined state with a key 40 and a set screw 41. On the outer periphery of the inner ring 38, several steel balls 42 and a retainer 43 prevent the outer ring 39 from playing with respect to the inner ring 38. It is rotatably mounted.

A dust cover 44 is welded to the retainer 43.

The outer ring 39 is a combination of a rigid body and an elastic body, and is formed, for example, by simultaneous molding of polyacetal and rubber.

Both kneading wheels 37, 37 are attached so that their eccentric directions are the same and their inclination directions are opposite to each other.

Of the pair of massaging wheels 37.37, the massaging wheel 37 on the gear box 45 side has a magnet 46 attached to the side surface of its inner ring 38, and the reed switch LS is fixed to the corresponding gear box 45 as shown in FIG. And this reed switch LS
Connect as shown in Figure 8.

In FIG. 8, SW1 to SW4 are switches attached to the operation part 47 arranged on the side of the armrest 6 of the reclining chair 2, SW1 is a power switch, SW2 is a switch for raising and lowering the kneading wheel 37, and SW3 is a switch for raising and lowering the massaging wheel 37. The kneading switch, S'vV4, is a rolling switch.

MS is a limit switch, which is attached to the side of the mechanism section A, and has stoppers 49 and 49 on the upper and lower outer surfaces of the guide rail 8, respectively.
50 is provided so that when the mechanism part A reaches the upper end of the guide rail 8, the stopper 49 activates the limit switch MS, and when the mechanism part A reaches the lower end of the guide rail 8, the stopper 50 activates the limit switch MS. I have to.

Now turn on the power switch SW-, and turn on the switch SW3.
When turned on to the D side, diode I)12 and resistor RIO
The transistor Tr1 is turned on through the gate, energizing the first solenoid SL1, and at the same time a signal is input to the 5th pin of the AND gate 1C through the resistor RB. Since an output is output from pin 10 of OR gate IC1, transistor Tr3 is turned on through resistor R8, relay R3'1 is energized, its contact a is closed, triac TR1 is turned on, motor M rotates clockwise, and the kneading operation is performed. Let's do it.

Next, when the switch SW3 is turned on to the E side, the transistor T r 1 is turned on through the diode D13 and the resistor RIO, and the first solenoid SL1 is energized.
An output is output from pin 1, turns on transistor Tr4, energizes relay RY2, energizes triac TR2, turns on triac TR2, and rotates motor M to the left to perform the kneading operation.

Next, when the switch SW2 is turned on to the B side, the transistor Tr1 is turned on through the diode DI□% resistor R1o, and at the same time the first solenoid SL1 is energized and the MS
The transistor Tr2 is turned on through the contact S1 of the second
Solenoid SL2 is also energized, and outputs are output from resistor RB → pin 6 of OR gate 1C1 → AND gate, pin 10 of C3 → pin 11 of OR gate cl.
Transistor Tr4 is turned on, relay Ry2 is operated, triac TR2 is turned on, motor M rotates to the left, and mechanism part A rises.

When the upper limit is reached, contact S1 of limit switch MS
is turned off, and only the second solenoid SL2 is turned off.
Mechanism part A stops rising.

Furthermore, at the same time that switch SW2 is turned on to B, switch SW2 is turned on.
If the D side of 3 is turned on, the AND gate IC3
Since no output is output to the 4th pin, priority is given to the operation of turning on the switch SW2, that is, the rising operation.

Next, when the switch SW2 is turned on to the C side, the solenoid SL1. At the same time as SL2 is turned on, the 2nd pin of C is turned on, and the 11th pin of C3 is turned on, and the 11th pin of C3 is turned on. Part A is lowered, and at the lower limit, contact S2 of limit switch MS is turned off, only second solenoid SL2 is turned off, and the lowering is stopped.

At this time, when the C side of switch SW2 is on and the E side of switch SW3 is on, the
Since no output is output to pin 3 of C3, the operation of turning on the switch SW2, that is, the lowering operation takes priority.

When performing rolling operation, when switch SW4 is turned on to the A side, transistor T r
1 turns on, the first solenoid SL1 operates, and at the same time turns on the transistor Tr2 through the contact S2 of the limit switch MS.
An output is output from pin 11 of pin or AND gate C2, turning on either triac TR2 or TR1 and rotating motor M to the left or right.

That is, the user begins to move up or down while massaging the object.

At this time, when the reed switch LS is turned on by corresponding to the magnet 46 while the kneading wheel 37 rotates once, the transistor Tr5 is turned on, the transistor Tr1 is turned off, and the first solenoid SL is turned off, causing rolling. You will be performing an action.

In this way, the rolling operation is started, but when the direction is upward, when the mechanical part A reaches the upper limit, the contact S1 of the limit switch MS turns off and the potential of the terminal T2 becomes zero, so that the flip-flop FF The output of triac TR2 is momentarily reversed and TR1 is turned off.
is turned on and mechanism section A begins to descend.

That is, it rolls downward.

When the mechanical part A reaches the lower limit, the contact S2 of the limit switch MS turns off and the potential of the terminal T1 becomes zero, so the flip-flop FF is inverted and the triac TR
2 turns on and rolls upward.

In this way, it automatically reverses itself at the upper and lower limits and continues rolling.

Also, if switch SW2 or switch SW3 is turned on at the same time as switch SW4, no output is output to pin 10 of ANDC3 and pin 11 of ANDC3, so the operation of switch SW4, that is, the rolling operation, is disabled. Make it a top priority.

The priority order and the operation of each part are tabulated as follows.

Capacitor C6, resistor RB, R21 are OR gate ■C
The transistor Tr3 is delayed switched in response to the output of the 10th pin of 1, and the capacitor C7, resistor R9,
R2□ is for delayed switching of the transistor Tr4 with respect to the output of the 11th pin of the OR gate Ic1, and is connected to the capacitor C1l and the resistor R11? The delay circuit constituted by R23 delays switching of the transistor Tr5 with respect to turning on of the reed switch LS when the switch SW4 is on.

Transistor Tr3. Tr4 delay is triac TR
1, TR2 is protected, and the delay of the transistor Tr5 reduces the variation in the spacing between the kneading wheels 37 and 37 during rolling.

A control block circuit diagram is shown in FIG.

The limit switch MS is operated by operating lever 5 as shown in Fig. 9.
1, and when the operating spring 52 contacts the stoppers 49 and 50, the operating lever 51
moves in the X or Y direction to open and close the contacts.

That is, as the mechanism part A rises, the operating lever 51 falls down in the X direction, and the switch spring 53 driven by the operating lever 51 separates from the terminal fitting 54, as shown in FIG.
When switch SW2 in the figure is in the rising position, the rising is stopped, and SW2 is in the rising position.
When 4 is on, it reverses from rising to falling.

At this time, the switch spring 53' is connected to the terminal fittings 54' and 55.
'Connected between the two and turned on.

On the other hand, when the switch SW2 is lowered, the operating lever 51 falls in the Y direction, and the switch spring 53'
moves away from the terminal fitting 55' and stops descending, and the switch S
When W4 is on, the operation is reversed to rise.

At this time, the switch spring 53 is in contact with the terminal fitting 54.

Moreover, if no external force is applied to the operating lever 51, it is of a return type, returning to the center position as shown in FIG.

Next, the motor M and the bearing 56 of the pulley shaft 16 are connected to the first
As shown in Fig. 1, the belt 14 is electrically connected to a terminal 57 and a conductor 58, and the pulley shaft 16 is supported by bearings 56 and 56' in a housing 59 made of an electrical insulator such as plastic. It can bypass static electricity, prevent discharge due to static electricity, and prevent adverse effects on electronic circuits.

Incidentally, FIG. 11 is a sectional view taken along the line X--X of FIG. 11a.

Also, the first solenoid SL1 and the second solenoid are
As shown in Fig. 2, by winding the winding 62 around a pair of frames 61 fixed by rivets 60 and attaching the plunger 26, the number of parts can be reduced and the cost can be reduced, and installation is easy. , the heat dissipation area is large, the temperature rise is low, and it can be made smaller.

Note that 63 is a thermos switch and other protective devices.

In addition, the reed switch LS, which turns on the contacts by the magnet 46 attached to the kneading wheel 37 at the initial stage of operation of the switch SW4, is connected to the kneading wheel 37 when the switch SW4 is turned on.
This is to stop the rotation of the kneading wheel 37 at a predetermined position regardless of the rotational position of the kneading wheel 7, and to position the kneading wheel 37 at a position suitable for rolling.
