Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a chair-type pine surgery machine, and in particular, an object of the present invention is to provide a pine surgery machine that can perform appropriate treatment according to individual differences.

[Background of the invention]

Conventionally, in equipment that performs pine surge by vertical movement and rotation of kneading wheels tilted in the opposite direction,
In particular, as a method for setting the width of both wheels to an appropriate width according to individual differences in back straightening, a method has been proposed in which the rotational position of the kneading wheel is detected by a reed switch or the like and the position is controlled. However, according to this method, the detection section is complicated and expensive, and reliability problems may arise such as malfunctions due to external magnetic fields of the detection switch (when used in combination with a magnetic therapy device, etc.).

[Purpose of the invention]

In order to eliminate the above-mentioned drawbacks, the present invention is designed so that the width of the grinding wheel can be arbitrarily set simply by controlling the electric motor with a switch that can be energized for a short time, such as a flash switch, and the width of the grinding wheel can be set arbitrarily. The purpose of the present invention is to provide a chair-type pine surge machine which is small in number and is naturally less likely to suffer from adverse effects due to external factors.

[Effect]

In order to achieve the above purpose, the operating speed of the treatment section must be extremely low (several tens of rpm).
rpm), and by focusing on the general pine surge mechanism that connects the two through a wide speed reduction mechanism, by controlling the drive time of the motor in units of seconds, the result is a reduction in the massaging wheel. This allows the rotation angle to be controlled within a small range.

3' to a plunger 46 which is driven and controlled by a solenoid 44 and a spring 45.

On the other hand, the gear 34 that can be loosely fitted onto the pulley shaft 30 is connected via a reduction gear 47 to a rotating shaft gear 49 that is integrally attached to the rotating shaft 8 of the kneading wheel 17.

Reference numeral 54 denotes the operation section of this pine surge machine, which is connected to the main body 1 by a cord 61, and the operation switches include a back straightening and massaging selection switch 55;
A selection switch 56 for kneading and pushing, a kneading width setting switch 57, a kneading position control switch 58, and a power switch 59 are installed. This kneading width setting switch 57 is connected to a flash circuit 62, and when the switch 57 becomes conductive, the transistor Q ₁ is activated, and the relay ₆₀ is activated to start the motor 26 _clockwise . After the time set by Q ₁
The base potential of becomes higher and the transistor _Q1 becomes
OFF, the relay 60 is turned OFF, and the clockwise rotation of the motor 26 is stopped.

Next, the operation of this pine surge machine will be explained.
The practitioner sits on the seat 2, rests his or her back against the backrest 3, and then operates the switches on the operating section 54. First, after turning on the power switch 59, the selection switch 55 for, for example, back stretching or kneading is set to, for example, back stretching. Then motor 26
rotates and the solenoid 44 is energized,
The operating rod 43 is pulled toward the right in FIG. 3 against the spring 45, and the operating rod 43 presses the idler 40 toward the left in the drawing via the fulcrum 43', and the transmission surface 39
engages with the engagement surface 38 of the worm 36 and transmits the rotational force of the pulley shaft 30 transmitted via the motor 26 and the belt 28 to the worm 36. As the worm wheel 52 rotates and the rotating screw 51 integrated with the worm wheel 52 rotates, the massaging section 18 including the drive mechanism is moved along the backrest section 3 by the thrust generated by the screw shaft 50 and the rotating screw 51. The kneading ring 17 moves along the spine of the practitioner and produces a back stretching effect while applying compressive force. The vertical movement is detected by limit switches (not shown) attached to the upper and lower ends of the massaging guide rail 20.
This is done by switching the rotation direction of the motor 26.

On the other hand, when the practitioner desires partial pine surgery, the selection switch 55 is turned on. Then, although the motor 26 continues to rotate, the solenoid 44 is released and the operating rod 43 is pulled toward the left in FIG. 3 by the spring 45. Therefore, the action rod 43 presses the swinger 40 to the right in the figure via the fulcrum 43', disengages the transmission surface 39 from the worm 36, and then disengages the transmission surface 39'.
engages with the meshing surface 37 of the gear 34 and transmits the rotational force of the pulley shaft 30 to the gear 34. This rotational force is then transmitted through the reduction gear 47 to the rotating shaft 8. At this time, if the selection switch 56 for kneading and pushing on the operating section is on the "kneading" side, the rotating shaft 8 will rotate clockwise in FIG. 5. Therefore, at this time, the ball 10 first rolls clockwise on the eccentric shaft 9, but soon the ball 10 is clamped by the inclined portion 13 of the clutch body 14 and the eccentric shaft 9, and as a result, the clutch body 14 is rotated. It rotates together with the rotating shaft 8. For this reason, the kneading wheel 17 as a whole rotates at an inclination, and a kneading action is performed by increasing or decreasing the width of the kneading wheel relative to the treatment area due to the inclination, and by increasing or decreasing the treatment depth due to the eccentricity 2×e of the eccentric wheel 9. .

If the selection switch 56 is set to "push", the motor 26 rotates in the reverse direction, the eccentric wheel 9 rotates counterclockwise in FIG. 5, and the ball 10 moves idly toward the rising portion 11 of the clutch body 14. . Therefore, the clutch body 14 does not rotate, and as a result, the width of the massage ring 17 remains the same, and only the displacement amount 2xe by the eccentric ring 9 acts as an increase or decrease in the treatment depth, resulting in a so-called pushing effect.

However, if the user wishes to adjust the treatment width (that is, increase or decrease the width by rotating the massage wheel) during the pushing action, the massage width setting switch 57 is turned on. Then, the relay 60 is activated to reverse the rotational direction of the motor 26, and the kneading wheel 17 rotates clockwise in the figure by the same system as during the kneading operation, and the kneading wheel width begins to increase or decrease. However, in this case, since the operating time of the relay 60 is extremely short, the kneading wheel rotates by (a few minutes), and the width of the kneading wheel 17 remains at that position, that is, the width increases or decreases, and the pushing operation is performed again. to go into.

Next, the rotational direction of the operating section 54 and the motor 26 and the driving relationship of the solenoid 44 will be explained with reference to the block diagram of FIG. The back straightening and kneading selection switch 55 switches between energizing and opening the solenoid 44. For example, when it is desired to perform back straightening, the solenoid is switched to the energized state. At this time, when the kneading position control switch 58 is switched, the rotation direction of the motor is changed, and the position of the kneading section can be moved. Further, when the switch 55 is switched to the solenoid open state, the kneading operation and the pushing operation can be performed by the changeover switch 56 by controlling the position and direction of the motor 26, as described above.

Next, when the width setting switch 57 is pressed, the above-mentioned flash circuit 62 causes the switches 56, 58 to
Regardless of the setting, the motor 26 rotates clockwise for a short period of time, and the massaging width can be set.

That is, at this time, if the switch 56 is in the pushing operation state (counterclockwise rotation), the motor 26 is reversed as described above and the width setting is performed for a short time, and if the switch 56 is in the kneading operation state (clockwise rotation). The massage width setting switch 57 is ignored. Also, when the selection switch 55 is set to straighten the back,
That is, when the massaging width setting switch 57 is pressed while the solenoid 44 is in the energized state, the solenoid 44 is opened for a short time and the motor 26 rotates clockwise, allowing the massaging width to be set.

It should be noted that during the back straightening operation, the screw shaft 50 that causes vertical movement must be straight in manufacturing. is good. Therefore, the mechanical part placed on the motor base 25 moves up and down linearly along the screw shaft 50, but the kneading part 18 and the mechanical part are connected to the pulley shaft 30.
A connecting bearing 53 is connected between the rotating wheels 8 of the rubbing wheel 17.
The guide rails 20 and 20' are connected by a connecting arm 24 which is rotatable by a bearing 23. Therefore, if the guide rails 20 and 20' are formed in a curved line along the frame, the movement will be made as the mechanism moves up and down in a straight line. Even if the massaging section 18 moves in a curve, it can operate without changing the distance between the pulley shaft 30 and the rotary shaft 8 due to the rotation of the connecting arm 24.

[Function and effect]

Since the present invention has the above-described configuration, the following effects can be obtained.

In other words, the width of the kneading wheel can be set simply by controlling the rotation time of the motor using a flash switch, which eliminates the need for kneading wheel position detection components and their control circuits, making it possible to provide inexpensive and highly reliable products. The rotation angle of the kneading wheel can be adjusted arbitrarily by simply changing the operating time of the flash switch, and since no reed switch is used, it can be used in combination with magnetic therapy, allowing for comprehensive treatment, and its effects are remarkable. be.
