Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair-type pine-surgery machine, and particularly to a chair-type pine-surgery machine with an MS configuration that can perform optimal pine-surgery motion along the back of the human body.

Generally, it is necessary for a pine surgery machine to have the function of performing all 3wJ operations such as stretching, kneading, and pushing, and in order to achieve this, especially in a chair-type pine surgery machine that performs pine surgery on the back of the human body, conventionally, the treatment section has been made movable. A movable drive source pine surge@barrel has been proposed in which the drive source is attached to the treatment section. One form of this is to move the treatment area by rotating a screw shaft, but with this method, the locus of movement of the treatment area is a straight line, so treatment cannot follow the curves of the human body, and the pine surgery effect is poor. The problem of uniformity arises. In order to solve this problem, a method has been proposed in which the treatment section is moved together with a drive motor on a curved guide rail formed on the backrest. According to this method, the unevenness of the pine surge effect can be solved. But 1
Since the posture of the drive motor changes along the curved edge, the direction of gravity applied to the motor rotor changes, causing problems such as vibrations and lubricant leakage. As a result, a rank is provided in the guide rail portion, and a pinion that meshes with the rack is used for safety, but compared to a moving means using a screw shaft, there is a problem that a complicated transmission thread is required.

The features of the present invention include a massaging section which is attached to two massaging machines by tilting them in opposite directions to the rotating shafts that serve as their driving sources, and a backrest section. A guide part is fitted into a guide rail provided in a curved shape along the curve of the backrest part on the side and guides the movement of the massaging part rotation axis, and a guide part is fixed in a straight line in the vertical direction at the rear position of the backrest part. The foot engages with the screw shaft installed on the screw shaft and is moved up and down along the screw shaft by applying a rolling force from the outside, while the massaging section rotation shaft is guided by the guide section and moves up and down. A rotating screw to be moved, and an upper part that moves up and down along the screw axis due to the vertical movement of this rotating screw,

It is freely rotatably fitted onto the pulley shaft 3o via the silk (Fig. 3). The pulley f#ll 30 has both ends attached to the pulley 111 receiver 3 provided on the side wall 31.31' of the motor base 25.
2. Suspended by 32' motor pace 25
A pulley 27 that is integrated with the drive shaft 26' of the motor 26 mounted above, this pulley 27! The rotation of the motor 26 is transmitted to the pulley shaft 30 by integrally attaching the driven pulley 29 to the pulley shaft 30 via the belt 28 . The pulley shaft 30 is provided with a gear 34 which is rotated by a gear bearing 33, and a worm 36 which is freely rotated by a worm (first bearing 35). The meshing surfaces are 37 and 38, and these meshing surfaces [
The key 4 is placed so that the idler 40 having transmission surfaces 39 and 39' that engage with the pulley shafts 37 and 38, respectively, can slide freely in the axial direction with respect to the pulley shaft 30 and transmits only rotational force.
1 has a loose iron layer. The slider 40 is controlled to slide in the @ direction by an operating rod 43 that engages with a recess 342 formed on its outer surface.

The operating rod 43 is connected via its fulcrum 43' to a nozzer 46 which is driven and controlled by a solenoid 44 and a spring 45. Further, a screw shaft 50 (FIG. 2 to FIG. 4) having a shape of 100 mm is fixedly attached to the leg portion 5 of the pine surge machine body 1 in the vertical direction, and the length of the screw shaft 50 is the same as that of the pine serge machine. It has a length sufficient to cover the entire upper and lower area of the backrest 3 of the machine body 1, and its upper end is fixed to the upper end of the pipe frame 19, 19' via a pipe frame 19'', and the screw shaft 5o A thread cut on the outer circumference of the worm wheel 52 engages with a rotating screw 51, and a worm wheel 52, which is integrally connected to the rotating screw 51, engages with the worm 36 on which the pulley shaft 3 (HC is playing). Also, the pulley shaft 3o
The gear 34, which is loosely located, is connected to the rotating shaft 8 of the kneading wheel 17.
It is coupled via a reduction gear 47 to a rotating shaft gear 49 that is integrally attached to the rotary shaft gear 49 . As described above, the drive of the present invention! 1
Department will be formed.

Next, the operating section will be explained with reference to FIG. Operation unit 54
is connected to the pine surge machine body 1 using the cord 61,
The operation switches include a selection switch 55 for back stretching and massaging, a selection switch 56 for massaging and pushing, a massaging width setting switch 57, and a massaging position control switch 58.1! [The source switch 59 is provided. The kneading @ setting switch 57 is connected to a flash circuit 62 shown in FIG. 8, and when the kneading width setting switch 57 becomes conductive, the transistor Q is activated, and the relay 60 is activated to start the motor 26. When the time set in advance by the resistor R1 capacitor CK has elapsed, the pace potential of the transistor Q becomes low, the transistor Q is turned off, the relay 60 is turned off, and the rotation of the motor 26 is stopped.

Next, the operation of the actual example will be described. 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, turn on the power switch 59, and then turn the kneading selection switch 55 to set the kneading selection switch 55 to stretch the back suji.Then, the motor 2
6 rotates, the solenoid 44 is energized, and the operating rod 43 is pulled toward the right in FIG. 3 against the spring 45.
The action rod 45 presses the idler 40 to the left via the fulcrum 43', the transmission surface 39 engages with the meshing surface 39 of the worm 36, and the pulley shaft 30, which is rotationally driven by the motor 26 and the belt 28, is rotated. The rotational force is transmitted to the worm 36. As a result, the worm wheel 52 rotates, the rotary screw 51 integrated with the worm wheel 52 rotates, and the massaging portion 18 including the drive mechanism is moved to the backrest portion 3 by the thrust generated by the rotary screw 51 and the screw shaft 50. The massager 17 and 17' move along the spine of the practitioner, applying compressive force and producing a muscle stretching effect. The direction of the vertical movement of the massaging section 18 is changed by detecting the position using limit switches (not shown) K attached to the upper and lower ends Km of the guide rail 20, and by switching the direction of rotation of the motor 26.

On the other hand, when the practitioner desires partial pine surgery, the selection switch 55 is turned to "massage". Then motor 26
The rotation remains as it is, but the solenoid 44 is opened and the first action rod 43 is pulled toward the left in FIG. 3 by the spring 45. Therefore, the action rod 43 presses the idler 4o to the right via the fulcrum 43', and the transmission surface 39 and the worm 36
At the same time, the transmission surface 39' engages 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 transmitted to the rotating shaft 8 via the reduction gear 47. At this time, if the kneading/push selection switch 56 on the operating section is set to the 1" side, the rotating shaft 8 will rotate clockwise in FIG. However, the balls 10 are immediately clamped by the inclined portion 13 of the clutch body 14 and the eccentric wheel 9, and as a result, the clutch body 14 rotates integrally with the rotating shaft 8. Therefore, the massaging wheel 17 is rotated as a whole. This tilt rotation causes a kneading action to be performed by increasing or decreasing the massage width for the treatment area and by increasing or decreasing the treatment depth due to the eccentricity 2xe of the eccentric wheel 9.

In addition, if the selection switch 56 is set to "1 press", the motor 2
6 rotates in the opposite direction to the above, the rotating shaft 8 and the eccentric wheel 9 rotate counterclockwise in FIG. 5, and the ball 10 approaches the rising portion 11 of the clutch body 14 and idles. Therefore, the clutch body 14 does not rotate, and as a result, the massaging wheel 17 1@
is up to that t.

Only the displacement 12Xe caused by the eccentric wheel 9 acts as an increase or decrease in the treatment depth, producing a so-called pushing effect.

If the practitioner wishes to adjust the treatment (i.e., increase or decrease the number of massage wheels by rotating the massage wheel) during the above-mentioned pushing action,
Turn on the kneading Ia setting switch 57. Then, the relay 6o is activated and the rotation direction of the motor 26 is reversed, and the trap and kneading wheel 17 rotate clockwise and the kneading shaft wheel starts to increase and decrease as in the case of the kneading operation. However, in this case relay 6
Since the operation time of o is extremely short, the kneading wheel is 1/(several minutes).
Rotate and stop. Thereafter, the motor 26 rotates normally again, so that the width of the massaging wheels 17, 17' remains at that position, that is, the width increases or decreases, and the pushing operation begins again.

It should be noted that during the above-mentioned back straightening operation, it is advantageous in terms of manufacturing that the screw shaft 50Fi that causes vertical movement is linear, but on the other hand, as a treatment effect, the massaging part 18 moves along the skeleton of the user. It's good to do it. In carrying out the present invention,
Therefore, the mechanical part placed on the motor base 2b moves up and down along the screw shaft 50, but the kneading part 18 and the motor base 25 are connected between the pulley shaft 30 and the rotating shaft 8. They are connected by a connecting arm 24 which is rotatable by bearings 53 and 23, so that the guide rails 20, 20' are formed into curves that follow the skeleton of the practitioner, and the massaging portion 18 is connected to the motor base 25. II! Vertical movement IC year, even if it moves up and down in a curve, the connecting arm 24
The pc is set so that the pulley shaft 30 and the rotary shaft 8 can operate without changing the distance between them due to zero rotation.

As explained above, according to the present invention, the drive unit including the motor is configured to move up and down linearly along the screw shaft, so the attitude of the motor etc. with respect to the direction of gravity is always constant, unlike conventional There is no fear that the motor rotor will move due to changes in the direction of gravity, which was a problem with technology, and stable rotation and quiet operation can be achieved.Also, the oil retaining mechanism prevents lubricating oil from flowing out in the same direction. ), and furthermore,
Since the massaging section is configured to move along the curve of the human body, it is possible to perform a uniform massage operation on the human body.
