Description

[Detailed description of the invention] This invention relates to a pine serge chair.
The purpose is to provide a pine-surge chair in which the kneading force can be easily adjusted.

Examples will be described below using figures. 1st
Figures 1 to 6 show an embodiment of the present invention, in which 1 is a backrest part, and two backrest parts 1 are arranged at appropriate intervals so that both sides of the back of the patient are in contact with each other. has been done. Reference numeral 2 denotes a disk-shaped massaging wheel disposed between the backrest portion 1. The two massaging wheels 2 are spline-connected to the output shaft 4 of the gearbox 3 in an inclined eccentric manner, and the outer peripheral ring of the massaging wheel 2 is slidable in the circumferential direction. Since this kneading wheel 2 is rotatably driven by a motor 5 via a gear box 3, the kneading wheel 2 periodically projects forward and reciprocates in the left and right direction (arrow A). The kneading motion is starting to be performed. A pinion 6 is attached to both ends of the output shaft 4, and the pinion 6 is attached to a rack 9 of a guide rail 8 fixed in parallel with the frame 7.
By meshing the kneading wheels 2, the kneading mechanism section 10 equipped with the gearbox 3 and the motor 5 can be moved up and down while rotating the kneading wheels 2. Reference numeral 11 denotes an air bag made of flexible synthetic resin. It is interposed in between. Each of the back support plates 12 and 13 has a sliding piece 15.
(a) Sliding guide portions 15 consisting of guide claws 15b are provided at appropriate intervals to prevent the back support plate 12 from shifting in the surface direction.
Reference numeral 16 denotes an air amount adjusting section consisting of an air pump 17 and a solenoid valve 18, and the air amount within the air bag 11 is adjusted by driving the air pump 17 and the solenoid valve 18 by operating a switch. Reference numeral 19 designates a kneading wheel cover that covers the front surface of the kneading wheel 2, 20 a handle for adjusting the angle of the backrest 40 with respect to the seat portion 21, 22 a hose, 23 a base frame, 40 a backrest, and 41 a headrest. .

Now, if the solenoid 24 of the solenoid valve 18 is energized by a switch operation so that the output shaft 25 is driven rightward, the valve body 26 will move rightward and the air supply port 27 and the air supply port 28 will communicate with each other. Compressed air is sent from the air pump 17 to the air supply port 27 and the air supply port 28.
It is fed into the air bag 11 through the air bag 11. 26a in the figure
is an O-ring. Therefore, the air bag 11 expands (as the amount of air increases, the cross section becomes closer to a circle), and the backrest portion 1 moves forward with respect to the frame 7. By the way, kneading wheel 2 is frame 7.
, the relative position in the front and back direction changes so that the distance between the backrest 1 and the massaging ring 2 increases, and the patient can lean against the backrest 1. When performing pine surgery treatment, the pressure force of the kneading wheel 2 against the treated person becomes weaker, and the kneading force becomes weaker. On the other hand, when the solenoid 24 of the electromagnetic valve 18 is de-energized by a switch operation, the valve body 26 is moved to the left by the return spring 29, and the air supply port 28 and the exhaust port 30 are communicated with each other, causing an air bag. The air inside 11 is exhausted. Air bag 11
Since it has flexibility, it becomes flat when air is exhausted, and the backrest portion 1 moves in a direction approaching the frame 7, that is, backward. Therefore, the pressing force of the kneading ring 2 against the patient becomes stronger, and the kneading force becomes stronger. As described above, by appropriately adjusting the amount of air in the air bag 11 and moving the backrest part 1 in the front-back direction, and changing the relative position of the backrest part 1 and the massaging ring 2 in the front-back direction, massaging is performed on the patient. This makes the force adjustable.

Figures 7 to 10 show other embodiments,
The kneading wheel cover 31 that covers the front surface of the kneading wheel 2 is made of two vinyl chloride sheets welded together using high-frequency welding or the like to form a bag shape. Bag body 3
The right bag body 31
The hot air flowing in from the inlet 33 provided at the lower end of a flows through the path of inlet 33 → right bag 31a → communication hole 32 → left bag 31b → outlet 34. The air flowing out from the kneading wheel cover 31 is reheated by a hot air circulation device 35 consisting of a circulation fan 35a and a heater 35b, and then flows back in from the inlet 33.
It is circulating inside. In this case, the massaging wheel cover 31 heated by hot air comes into contact with the back of the patient, and the massaging force of the massaging wheel 2 is applied to the patient's back, so that the pine surge treatment and the thermal treatment are performed at the same time. Effective pine surge treatment can be performed. 37 in the diagram is armrest 38
This is a changeover switch located in the In addition, the 10th
As shown in the figure, a changeover switch 37 may be used to switch between heat treatment and pine surge treatment.
In the figure, AC is an alternating current power supply, and 39 is a circulation fan drive motor.

The present invention is constructed as described above, and an air bag is interposed between the backrest part that corresponds to both sides of the patient's back and the frame that supports the backrest part. By adjusting the amount of air in the backrest, the backrest can be moved in the front and back direction, and the relative position of the backrest in the front and back direction can be changed as appropriate. Therefore, there is an advantage that the kneading force for the person to be treated leaning against the backrest and undergoing pine surge treatment can be adjusted according to preference.

Claims (1)

[Scope of utility model registration request] Between two backrests arranged at appropriate intervals so as to touch both sides of the back of the patient, a massage ring is arranged that can slide freely along a frame that supports the backrests from the back. In the Matusage chair, a flexible air bag is interposed between the backrest part and the frame, and an air volume adjustment part is provided to appropriately adjust the amount of air in the air bag. This Matusage chair has a backrest that can be moved forward and backward by adjusting the amount of air.
