Description

[Detailed description of the invention] Unexploded r#4 is related to a chair-type pine surge machine, and sometimes 1vA
Our goal is to provide Pine Surgage tAK, which allows for careful treatment depending on individual differences.

Conventional equipment tilts in the opposite direction and performs pine surge by vertical movement and rotation of the massager.

As a method for setting the width of both wheels to an appropriate width according to the 1+m difference between people during back stretching, a method has been proposed in which the rotational position of the kneading wheels is detected by a reed switch and controlled If&1IIJ. However, according to this method, the detection part
4I is complicated and expensive, and malfunctions due to the external S magnetic field of the detection switch (such as when used in combination with m-air therapy 4) often cause an open circuit in the fA plane.

In order to eliminate the above-mentioned drawbacks, the present invention makes it possible to arbitrarily set the width of the milling wheel by simply controlling the 11-movement automatic transmission switch, and the number of parts is small. The purpose is to provide a chair-type pine surge machine that is less likely to cause local damage due to foreign causes.

In order to achieve the above objective t'', the operation speed of the treatment section needs to be extremely low (several IQ rpm), but the drive motor is very fast (WX 1,000 rpm), and there is a large width between the two. Focusing on the general pine surge mechanism that is connected via a slow-reduction mechanism, the motor drive time is reduced in units of several seconds, and as a result, the rotation angle of the massage wheel can be controlled within a small range. This is how it was done.

When the switch 57 becomes conductive, the transistor Q is activated, and the relay 60 is activated, causing the motor 2 to
I will start it at 6', but please do about 1. When the time set by C8 has elapsed, the pace potential of the transistor Q1 becomes high, the transistor Q becomes 0FFL, the relay 60 is turned off, and the 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 and rests his or her back on the backrest s3, and then operates the switch on the operating section 54.

First, turn on the power switch 59t, and then set the selection switch to either back stretching or kneading if the row is 59t, and set it to back stretching if the row is 55t. Then, as the motor 26 rotates, the solenoid 44 is energized, and the operating rod 43 is pulled toward the right in FIG. s3 against the spring 45.

The operating rod 43 pushes the idler 40t to the left in the figure via the fulcrum 43', and the transmission [1i39] engages the engagement ring 38 of the worm 36, and the motor 26. The rotating paper force of the pulley shaft 3o transmitted via the belt 28 is transmitted to the worm 36, and the worm wheel 52 rotates for 1 ms.
The rotating screw 51 integrated with the rotary screw 51 rotates and the massaging section 18 including the above-mentioned drive mechanism bends the back by the thrust generated by the screw shaft 50 and the rotating screw 51 and massages the spine of the practitioner. The ring 17 provides a compressive force and produces a back-stretching effect. Attach KJ to the upper and lower ends of the improved lower IIbIb guide rail! This is done by detecting the position using a switch (not shown) and switching the direction of rotation of the motor 26.

On the other hand, general medical care is a part! When you want tsusage, turn on the selection switch 55t-massage. Then, the rotation of the motor 26 is tt, but the spring 45 causes the lever 43, which releases the solenoid 44, to rotate at the 31st position! ! l) Attracted to the left. Therefore, the working rod 43#i fulcrum 43'
Push the playback 4Qt to the right in the diagram through the
[39 and the worm 36 are disengaged, and the transmission surface 39' now engages the meshing surface 37 of the gear 34 to transmit the rotational force of the pulley shaft 30 to the gear 34. This rotational force is then transmitted to the rotating shaft 8 via the reduction tooth east 47. Selection switch 56 for kneading and pushing on this and 11 operation section
If it is on the 1-kneading side, the rotating shaft 8 will rotate clockwise in figure sg5. Therefore, at this time ball 10
The eccentricity is 1M at the beginning! 9 in the clockwise direction, the ball 10 is immediately clamped by the inclined portion 13 of the clutch body 14 and the circular shaft 9, and as a result, the clutch body 14 rotates integrally with the rotation @8. For this reason, the kneading wheel 17 as a whole rotates at an incline, and the kneading effect tm is exerted by the increase or decrease in the kneading wheel relative to the treatment area due to the inclination, and by the increase or decrease in the treatment depth by 1 core 2xeK of the pot center 9.

If the selection switch 561 is set to ``push'', the motor 26 will rotate in the opposite direction as described above, and the ball 10 will idle as it approaches the rising edge sI 111 of the clutch body 14. do.

Therefore, the clutch body 14r1 does not rotate, and the width of the clutch and massage wheel 17 remains the same, and the displacement 311 due to the l center 1119
Only 2x acts to increase or decrease the treatment depth, resulting in a so-called pushing effect.

However, if the massager adjusts the massage width t (i.e., increases or decreases the width by rotating the massage wheel) during the pushing action, he or she turns on the stile massage width setting switch 57t. Then, relay 60 will operate and motor 2! The direction of rotation is reversed, and the kneading wheel weight 7 rotates in the direction of the hour hand in the figure, and the mass of the kneading wheel starts to increase and decrease compared to #IC, which is the same system as during the Sakai period kneading action. However, in this case, since the operating time of the relay 60 is extremely short i, the kneading wheel rotates by rt (1/a minute) and then stops.

After that, the motor 26 rotates in the normal direction again, so that the width of the kneading hand 17 is at that position 11, that is, the width increases or decreases. Although it is necessary for the table that the axis 60 is straight, 1.
On the other hand, as for the treatment effect, it is good that the massage corridor 18 provides conductivity that is suitable for the skeleton of the medical treatment. Upper F
I encourage you.

The massaging dllllg and the above-mentioned structure are connected by a connecting arm 24 which is rotatable by a connecting bearing 53 and a bearing 23 between the pulley shaft 3o and the rotary ring 8 of the massaging wheel 17, and therefore the guide rail 20°20' If it is formed into a curve along the skeleton, even if the massaging section 1B moves in a curve as the mechanism section moves up and down in a straight line, the distance between the pulley shaft 30 and the rotating shaft 8 will not change due to the rotation of the connecting arm 240. It is designed to be able to operate normally.

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

In other words, the width of the kneading wheel can be set by simply controlling the rotation time of the motor using a flash switch, which eliminates the need for parts to detect the position of the kneading wheels 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 t of the switch, and since no reed switch is used, it can be used in combination with all-in-one treatment, resulting in comprehensive treatment.
The effect is remarkable.
