Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a massager mounted on a pedestal for massaging and treating the back muscles by meandering motion of a massaging ring on a chair, bed, examination table, or the like.

[Conventional technology]

Conventionally, as this type of massaging device, a massaging device has been proposed in which, for example, rings are provided on the left and right sides of the back of a chair and the rings are moved back and forth within the range of the backrest.

In addition, another method has been proposed in which the shoulder is tapped using a crank mechanism, in which a coin is inserted and the massage is performed for a predetermined period of time.

[Problem to be solved by the invention]

In the former of the conventional techniques, the ring is pressed against the back muscles, and the ring is simply pressed along the back muscles while repeating reciprocating motions. Unlike acupressure, the ring only presses linearly against the back muscles. Therefore, there is a problem that it cannot be expected to be effective as massage.

The latter method has the disadvantage that it merely taps the shoulders and cannot massage the upper body.

Therefore, the present invention was made in view of the above-mentioned conventional problems, and its purpose is to massage the back muscles on both sides of the spine using the body's own weight or pressure. The purpose is to provide a massaging device which can relieve the fatigue of the entire body by pressing against a ring and relaxing the muscles through a meandering motion, without causing any damage to the appearance.

[Means to solve the problem]

In order to achieve the above object, the massaging device of the present invention is formed into a substantially rectangular outer frame surrounded by an upper frame, left and right side frames, and a lower frame in which a motor is interposed, using a metal plate. An outer frame body is formed by vertically installing guide rods according to the number of guides on the back side of the frame body, and connecting plates are attached to the front and rear of the lower parts of the left and right side plates in the outer frame body. The inner frame body of the shaped mounting plate is installed internally,
A guide arm is provided in the center of the inner frame body to protrude forward,
A plurality of insertion holes are provided on the back surfaces of the guide arm and the left and right side plates, and the guide arms are slidably inserted into the opposing guide rods to regulate the lowering position. In addition, a rotating shaft and a starting shaft are constructed, a guide ring and a driving pin wheel are fixed to the rotating shaft, and the left and right ends of the shaft are attached to rubbing wheels rotatably attached to the left and right side plates, and the guide ring is connected to the The inner part is configured to be in sliding contact with the guide groove of the guide arm, further fixing a starting pulley to the starting shaft and a starting pin wheel to the end of the shaft, and applying tension by hanging a belt around the driving pin wheel and the starting pulley. Form a frame.

Next, as a driving means, a part of the belt is fixed to a connecting plate between the rear pin wheel attached to the motor inside the outer frame body and the pin wheel on the upper frame, and a part of the belt is fixed to the connecting plate and suspended from the inner frame of the outer frame body. A driven pin wheel supported by a shaft and the starting pin wheel are provided, an endless belt is suspended, and a plurality of rollers are attached in the middle to tension the belt.

[Effect]

At least three guide rods are installed vertically within the outer frame body firmly fixed to the outer frame. The inner frame is provided within the outer frame and is supported by guide rods for sliding movement. The guide arm provided inside the inner frame body has a guide groove provided in the front center thereof, projects forward, and has a rotating shaft and a starting shaft mounted thereon so as to perform a rotating action. That is, the rotating shaft has a guide ring, a driving pin wheel, and both ends of the shaft are fixed to the rubbing ring, and the guide ring moves up and down along the guide groove of the guide arm, and rotates together with the rotating shaft at the tip of the guide arm. A coaxial pin wheel is rotated by a belt, and an inwardly slanted kneading ring is projected forward to apply massage while moving up and down in a meandering motion.

Then, a part of the belt is connected to a rear connecting plate and suspended between a pin wheel provided at the center back of the motor below the guide rod in the center and a pin wheel provided above the pin wheel opposite to this pin wheel. Alongside this, a helical spring is connected to the guide arm and motor mount. Pin wheels for starting are attached to the top and bottom of the inner surface of the outer frame to suspend the belt, and a starting pulley is provided on the starting shaft and a starting pin wheel is provided at the end of the shaft to rotate the belt inside the inner frame. The belts in the inner frame are rotated by the belt rotation of the frame, and each belt is provided with a tensioning idler roller so that the rubbing ring can move up and down and rotate.
