Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pine surge device with a shiatsu mechanism, which is a rolling pine surge machine in which a rotary roller can be raised and lowered continuously and can be raised and lowered at will, with a shiatsu mechanism. It is something.

(Prior art and its problems) Several types of pine surgery machines have been developed to perform pine surgery on the back of the human body. A rolling pine surge machine that rubs and massages the back of the human body by screwing together a massaging member equipped with a massaging ball and moving it up and down continuously; Equipped with a mechanism and a beating mechanism, the rotary roller is moved up and down continuously, and the kneading mechanism and the beating mechanism are operated to massage the back of the human body, perform pine surgery, pounding pine surgery, rubbing pine surgery, and combinations of these pine surgery. Rolling pine surge machines and the like are already well known, and are especially useful to general users because they are easy to use and effective.

Incidentally, in recent years, an acupressure pine surge device has been developed in which the acupressure protrusions are configured to move in and out of the body, thereby making it possible to perform acupressure pine surgery on the back of the human body.

FIG. 1 and FIG. 2 show an example of the acupressure pine surge device. , 2, the cylindrical outer protrusion 4
and an inner protrusion 5 that moves up and down from inside the outer protrusion 4, and a support part 6 of the outer protrusion 4 is mounted on a guide rod 8 so as to be able to move up and down in a regulated manner, and the inner protrusion 5 The support part 7 of the outer protrusion 4 is mounted so as to be vertically movable within the support part 6 of the outer protrusion 4, and a cam surface 11 for vertically moving the support part 6 of the outer protrusion 4 is provided below both of the support parts 6 and 7. , a cam body 10 having a cam surface 12 that moves the support part 7 of the inner protrusion 5 up and down is provided, and while the outer protrusion 4 is held at the most protruding position, the upper part of the outer protrusion 4 is The inner protrusion 5 is configured to protrude and retract from the end face, and the outer and inner protrusions form two
It is possible to press the aspect of the body shape by the effect of appearing and disappearing in stages.

However, in the conventional acupressure pine surge device described above, although a two-step acupressure effect can be obtained using the outer protrusions 4 and the inner protrusions 5, the acupressure operation of these acupressure protrusions 2 is activated by the motor 13. Cam body 10
The engagement between the cam body 10 and the acupressure protrusion 2 is achieved by the rotation of the acupressure protrusion 2.
The contact structure is such that the lower surface of the cam body 10 is only supported by the cam body 10.

Therefore, when this acupressure pine surge device is used, there is no problem in using it in the normal position as shown in the figure, since there is no structure to hold the cam body 10 and the acupressure protrusion 2. When used in the reverse position (upside down state), each cam roller 9 of the acupressure protrusion 2 does not come into contact with the cam body 10, and only the cam body 10 idles, causing the acupressure protrusion 2 to protrude and retract. There is a problem that the support part 6 does not work.
Even when the acupressure protrusion 2 and the guide rod 8 are firmly engaged, the acupressure protrusion 2 that has protruded at one end does not return to its original position, resulting in the same problem as above that it cannot be moved in and out.

Therefore, in this type of conventional acupressure pine surge device, the range of use and the angle of use thereof are limited, and problems such as noise with the cam body due to impact have also occurred.

However, in recent years, in order to solve the various problems mentioned above, a cover sheet has been installed inside the cover sheet, and by rolling and sliding, it moves back and forth in a direction perpendicular to the back near the roller that massages the back muscles. A structure (Utility Application No. 161555/1983) in which an acupressure member for applying acupressure is provided and the forward and backward speeds of this acupressure member are made different is used, and the massage of the back by the roller and the acupressure by the acupressure means are performed. Pine surgical tools have been devised that can be performed advantageously.

However, in the case of this pine surgical machine, the acupressure mechanism of the acupressure member is arranged as an acupressure member between rollers, and includes an acupressure rod whose rear end is pivoted to a rocking plate with a pin, and a tip of the acupressure rod. an acupressure roller that is axially pressed, a long hole formed at the tip of the acupressure stick, a pin that is loosely supported in the long hole, a support plate that supports the pin, and a support plate disposed behind the acupressure stick. a rocking plate having a long hole, a gear engaged with the long hole of the rocking plate and driven by a second motor, and a pin on the gear that can be driven by a driven gear meshing with the gear. Because of this structure, when the driven gear rotates once, the pin makes one reciprocation in the elongated hole, and the pin also makes one reciprocation in the elongated hole formed at the tip of the acupressure stick, and the rocking plate Since the part connecting the acupressure stick and the acupressure stick are always chasing the rocking miracle, the two types of long holes are easily damaged and deformed, and the connecting part that is chasing the rocking miracle is also in constant sliding contact between the two. Since the acupressure stick is connected in a fixed state, there is a drawback that the breakage rate is high.Furthermore, the part that connects the rocking plate and the acupressure stick constantly follows the rocking miracle, so the tip of the acupressure stick cannot make linear reciprocating motion. Since the device repeatedly moves back and forth while rocking, there is a problem in that the load on the connecting portion and the engaging portion is large, shortening the life of the product.

(Object of the Invention) In view of the above-mentioned various problems, the present invention has been developed by making it possible to forcibly move the acupressure prongs back and forth repeatedly in a straight line while holding them at all times, thereby achieving rolling pine surge and arbitrary positioning. The object of this invention is to provide a pine massage device with an acupressure mechanism that can perform rolling acupressure pine surges either singly or simultaneously.

(Structure of the Invention) That is, the pine surge device with acupressure mechanism of the present invention is a pine surge device that is installed in the back of a chair, and includes a vertical screw shaft that can rotate forward and backward in conjunction with a drive motor, and a vertical screw shaft on both sides thereof. An elevating mechanism consisting of a pair of vertical rails arranged in parallel, and an elevating body that is screwed onto the screw shaft and can freely move up and down along the vertical rail, and the elevating body of the mechanism is sandwiched between the central portions of the elevating mechanism. At the same time, a mechanism frame body in which a support traveling roller is disposed in a pinching manner at a portion relative to the vertical rail, a driving motor for acupressure attached to the mechanism frame, and a pair of protrusions that rotate in conjunction with the driving motor for acupressure are attached. A child guide plate, elliptical grooves carved in opposing faces of each of these protrusion guide plates, and guide pins loosely fitted in each of the elliptical grooves are each fixed in a protruding manner, Between each tip, there is a pair of opposing sliding plates on which a protrusion support plate with a plurality of acupressure protrusions protrudes, and a U-shaped cross section that slidably holds each of these sliding plates. an acupressure mechanism that can move up and down integrally with the elevating mechanism, and a rotary roller disposed on the elevating body near the acupressure mechanism so as to protrude toward the acupressure protrusion; It is characterized by consisting of the following.
