[Industrial applications]

 This invention has a kneading and kneading member pivotally supported at an eccentric position of a pair of semi-circular rockers, and an erection base to which the semi-circular rockers are fixed. The present invention relates to a rolling massager having both functions of massaging massage in a complicated three-dimensional direction to a peripheral area such as a roller massage to the back, waist, leg flats and soles.

[0002]

[Prior art]

 Conventionally, various types of roll-rotating type small massagers of this type have been provided.

For example, a massage elliptic spherical massaging member and a cylindrical massaging member are evenly arranged on the outer periphery of a cylindrical body equipped with a drive mechanism without any step, and a pair of massaging bodies are provided at the center thereof. Eccentrically arranged so that a rolling massage and a rubbing massage can be arbitrarily performed so that a step impact does not occur when the roll rotates, a compact roll-rotating massage device (No. 4-10819). A large roller is rotatably attached to each of the revolving three-pronged arms at the tip of each arm, and at least one of them is an eccentric roller, so that it can be used for physical treatment as well as rocking treatment. No. (Actual No. Sho 63-182746) and a cylindrical body equipped with a drive mechanism inside, and an elliptical spherical massaging member for massage and a cylindrical massaging member are connected to the cylinder. A roll-rotating compact type that can be rolled and massaged so that a pair of kneading bodies are eccentrically arranged in the center part and there is no step impact during roll rotation, As a massager (actual Kaihei No. 2-109 628) using a large number of eccentric kneading wheels, both ends of the connecting rod that passes through the axial through hole of the eccentricity provided in the middle of the kneading rod have circular holes. Passing and fixing, unequal numbers on the left and right sides, and a kneading bar with a kneading wheel group located in the center of a relatively small diameter is exposed at the opening part of the front end of the outer surface of the box where the opening is provided The eccentric wheel type kneading machine (Shukaihei 4-71927) that can be used for each part of the human body, has a wide operating area, has the effect of kneading at the same time, and at the same time can stimulate the acupoints of the human body. No.), and outside the backrest surface A pair of slanted bar rollers installed inside is installed on the inclined shaft part of the eccentric shaft of the crankshaft.The sliding shaft is composed of bearing balls and rolling contact and sliding contact are used together. Since they are fitted together and the inclined shaft part is made of engineering plastic, and the inner peripheral surface of the rubbing roller is made of resin sleeve, the eccentric dimension and the tilt angle of the rubbing roller can be made sufficiently large, and the rod roller can be made smooth. There is disclosed a massage device (actually, Kaihei No. 4-12 4147) which can be rotated.

[Problems to be solved by the device]

 However, each of these massage devices has a complicated structure, the whole device becomes large and heavy, and it is extremely inconvenient because it cannot be grasped and used when carrying it, of course.

Further, in a compact roll-rotating type massage device, when the eccentric contact pressure rotating roller is brought into contact with the user's local area, the contact pressure rotating roller as a whole rotates in series, so that the affected part of the user is affected. The contact part is only at each vertex of the contact pressure rotating roller.For example, when this is used for the back and shoulders of the human body, the contact locus is vertical at several points at equal intervals in the width direction of the back and shoulders of the human body. Most of the non-contact portion is a broken line in the direction and cannot be massaged. For this reason, in order to evenly contact the affected part of the human body, the user has to move the body or use it, or to frequently move the body of the massage machine.

Further, the above-mentioned massage device can only perform a rolling massage of the body part by simply rotating the rotating roll, and cannot perform a kneading massage, but a kneading massage and a roller massage in one device. It was not equipped and could not fulfill these two massage functions.

Therefore, the present invention aims to provide a rolling massage device for the purpose of improving the above-mentioned drawbacks.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention rotatably supports an electric motor shaft equipped with a reduction mechanism at an eccentric position of a pair of semi-circular rockers, and the electric motor shaft pushes the affected part of the body. On the other hand, an eccentric kneading and kneading member having a plurality of inclined arc outer peripheral surfaces capable of pressing in complicated three-dimensional directions is integrally fixed. Further, the eccentric kneading and kneading member is positioned such that its outer peripheral virtual circular arc surface is eccentric with respect to the shaft center, and the inclined curved surface included in the outer peripheral virtual circular arc surface is inclined with respect to the axial center of the drive shaft. , The pressing action in the three-dimensional direction from the axis to the direction of the substantially inclined surface can be performed, and the semi-circular rocking disc is rotated while the eccentric kneading and kneading member is rotated by the swinging rotation of the semi-circular rocking disc. It moves in parallel with the arc locus of the outer circumference of the robot so that a rhythmic vibration stimulus can be applied to the local part of the human body.

[0009]

[Action]

 In the rolling massager according to the present invention, the electric motor shaft is rotated by a switch ON (not shown) through a reduction mechanism as appropriate. Along with the rotation of the electric motor shaft, the kneading and kneading member fixed to the electric motor shaft starts to rotate, and the same effect as kneading and kneading is achieved by pressing the affected parts of the patient's body, the shoulder, back, and waist. You can treat fir and kneading.

In this case, the patient lies on his back, and the kneading and kneading operation is repeated by pressing the kneading and kneading member on the base of the neck and the muscles of the shoulder (trapezius muscle).

In the above operation, the eccentric massaging and kneading member including the pair of semi-circular rockers may be laterally fixed to a separately installed pedestal, or may be used. Massage may be performed as it is without using.

Next, while the pair of semi-circular rocking discs is repeatedly rocked and rotated in the circumferential direction, the patient is in a state of lying on the eccentric massaging and kneading member or in a state of sitting and extending his / her legs. If you apply pressure with most local parts of the lower limbs, such as the muscular layer of the buttocks, the posterior muscles of the thigh, and the posterior muscles of the lower limbs (flap), the eccentric kneading member will rotate. However, since it moves back and forth repeatedly, it is possible to give a fine rhythmic vibration, and this fine rhythmic vibration stimulation enhances the action on nerves and muscle strength, and the muscle weakness weakens and slows down. You can treat the effect when you have a numbness.
