Description

[Detailed Description of the Invention] The present invention relates to an improvement of a chair-type pine surge machine. With the forward and reverse rotation of the threaded rod inside the backrest,
An elevating frame is provided that moves up and down along the guide rail, the base of the swinging arm of the pine surge roller is pivotally supported on the frame, and when the elevating frame rises to near the folding position of the upper end of the backrest,
The frame is configured to rotate the neck roller provided at the upper end of the backrest in a clockwise direction to apply a pine surge to the neck, or the pine surge roller that has been raised to a position close to the folding position. A pine surgery machine is already well known, in which an arm is rotated counterclockwise and a shoulder is pressed by a pressing body attached to the tip of the arm. However, the former type does not have pine surge applied to the shoulders, so it gives a feeling of weakness to people with severe stiff shoulders. Moreover, in the latter method, only the acupressure is applied to the shoulders after the pine surgery roller finishes the pine surgery on the back, so there is a problem that the pine surgery is monotonous and changes slowly, making it difficult to feel satisfied after use.

Therefore, in the present invention, in order to solve the above problem, when the pine surge roller rises close to the shoulder flaps, the shoulder acupressure roller is lowered by the elevating frame, and at the same time the neck roller rubs the nape of the neck. This pine surge machine provides an excellent pine surge effect by simultaneously applying three types of pine surges: pine surge on the back using the pine surge roller, pine surge from the nape of the neck to the back of the head using the neck roller, and shiatsu-like pine surge on the shoulders. The drawings showing the embodiments of the present invention will be described below.

A guide rail 3 with a curved surface that follows the back of a person and a threaded rod 5 that is rotated in forward and reverse directions by a motor 4 are installed in the backrest portion 2 of the main body 1 of the pine surge machine. An elevating frame 6 is screwed to the elevating frame 6, and the bases of swinging arms 7, 7 are swingably supported on the upper end of the elevating frame 6 on the backrest side. Pine surge rollers 8, 8 and guide rollers 9, 9 are rotatably supported by a shaft 10 between the lower ends of the rollers. 11 connects the guide rollers 9, 9 to the guide rail 3
The spring 12 biasing in the direction is an acupressure arm having an acupressure roller 13 at its tip, and this acupressure arm has the acupressure roller 13 diagonally upward and is slightly in the center in the longitudinal direction of the arm. The rear portion is rotatably supported by a pin 14 on the outside of the side plate portion of the guide rail 3. Reference numeral 15 denotes a swinging lever in the shape of an inverted L. A neck rubbing roller 17 is attached to the lower end of the vertical rod portion 16 of this lever 15, and its bent portion is held by a pin 18 to the side of the guide rail 3. It is rotatably supported inside the face plate portion, and is attached so as to cross the acupressure arm when viewed from the side. One end of the horizontal rod portion 19 of the swinging lever 15 is connected to the other end of the lever 21, which is rotatably supported by a shaft 20 in front of the pin 14 of the acupressure arm 12, and the guide rail 3. They are connected by a shaft 23 passing through a long hole 22 drilled in the side plate portion. 24 is the shaft 20
The acupressure arm 12 is biased by this spring 24 so that the pine surge roller 13 side faces obliquely upward. 25 is the upper limit switch, 26
2 is a lower limit switch, and these switches 25 and 26 are designed to control the forward and reverse rotation of the motor 4 by switching by the lifting frame.

Since the present invention has such a configuration, the protruding pieces 6a protruding from both sides of the upper part of the elevating frame 6, which is raised by the normal rotation of the motor 4, will move when the pine surge rollers 8, 8 reach near the position of the shoulder flaps. It comes into contact with the tail of the acupressure arm 12 and pushes it up. Then, the arm 12 rotates counterclockwise about the pin 14, and the acupressure roller 13 rotates downward as indicated by arrow a in FIG. 4. The counterclockwise rotation of the acupressure arm 12 about the pin 14 also lowers the lever 21, whose one end is connected to the acupressure arm 12 by the shaft 20, while rotating about the pin 14. A swinging lever connected to the other end of the lever 21 by a shaft 23 through an elongated hole 22 is pulled. Therefore, the swing lever 15 is connected to the pin 18.
The scruff rubbing roller 17, which is attached to the end of the vertical rod, rotates clockwise as shown by arrow b in FIG.
The patient rotates to the position shown in Figure 5 while rubbing the nape of the neck and the back of the head.

In this way, at the same time as the neck rubbing roller reaches near the back of the head, the acupressure roller 13 presses the shoulder, applying acupressure-like massage to the shoulder. At this time, the pine surge roller 8 has reached the upper part of the scapula while performing a pine surge, and the lifting frame switches the upper limit switch 25, so the motor 4 rotates in the opposite direction and the lifting frame 6 begins to descend. With this lowering of the elevating frame, the acupressure arm and the swing lever rotate in the opposite direction to the above-mentioned directions about the pins 14 and 18, respectively, return to their original positions, and are tensioned by the spring 11.

In this way, the present invention uses a pine surge roller to move up from the lower waist area, and when it reaches near the shoulder blades, a rubbing pine surge from the neck to the back of the head starts at the same time, and when it reaches a position near the upper limit, In addition to the above-mentioned two types of pine surgery, acupressure-like pine surgery is applied to the shoulder area, so pine surgery with three different types of stimulation is applied at the same time, which is sufficient even for people with severe shoulder stiffness. This provides a practical pine surge machine that will give you a sense of satisfaction.
