Description

Electric roller massaging device

〔Technical field〕

TECHNICAL FIELD The present invention relates to an electric roller massage device used to massage a back by pressing a lower back, a back and a neck while sitting with a back stretched. (Background technology)

Conventionally, as a motorized roller massage device, a whole-body-size mat type is known. The power transmission device in the electric mouth massager is equipped with a pair of roller running guide rails with a built-in life-size stainless steel belt and a drive source motor at one end. The motor is equipped with an electric π-roller running belt with rollers attached to it. Then, both the starting mechanism and the terminating mechanism of the roller / traveling belt are combined into a set to provide a winding storage box and a drive motor, and the roller / traveling belt force travels from the starting mechanism to the folding mechanism. Then, it has to be turned back further by the turn-back mechanism and returned to the end mechanism (because the motor is a single unit), which is a "double belt structure of going and returning". A so-called double-wheel drive belt with a so-called "double-structure power motor" that returns from the final mechanism to the first mechanism via the folding mechanism, returns to the initial mechanism, and is stored in an empty take-up storage box to reciprocate it. Met.

Also, there is a case where a roller-massage device is built only in the back of the chair, but this has a vertical helical shaft attached to the back, and the worm shaft is pivotally attached to this helical shaft, and the helical shaft is rotated. In this case, the roller is rotated vertically.

By the way, the above-mentioned conventional electric roller massage device requires a certain degree of toughness and elasticity because a π-la running belt must be attached to the entire length of the whole body. It is necessary to attach a stainless steel belt to make it necessary.In addition, guide rails etc. are precisely installed to prevent trouble such as twisting and crossing while running the stainless steel belt, and many other auxiliary parts are also installed. In addition, it is inevitable to use a complicated, large-capacity, heavy-weight structure, such as a winding method, which requires a storage box. there were.

In addition, in the above-mentioned conventional products in which the roller massage device is built in the back of the chair, a large motor is installed in the seat, and a thick seat must be formed. It was difficult to move.

It is. In this configuration, a belt with a feed hole is inserted into the mouth guide along with the flange of the shaft bush. This ensures that the guide rails are fixed along the steps, so that the fir rollers draw an S-shaped curve. The belt with sprocket holes is provided with sprocket holes at regular intervals along the left and right sides 巻 and is wound around the pulley with engaging projections, so that it can be smoothly moved up and down without twisting. Since the limit switch provided with the sensor is protrudingly provided, the movement can be surely repeated in the vertical direction. A belt with a sprocket hole is inserted into the roller guide along with the flange of the shaft. The roller guide section has a simple configuration.

In the electric mouth massager having the above-described configuration, the S-shaped curve is formed on the back base in the lower portion into two convex curved surfaces and one concave curved surface in the front-rear direction, and in the middle portion into a long gentle concave curved surface, Is formed on a convex curved surface. As a result, the fir-mouth can move more specifically along the longitudinal S-shaped force, which is the ideal posture shape of the body.

In the electric roller massage device having the above structure, the back base is formed of a hard synthetic resin, and is formed in a forwardly curved bucket shape. It has a wing piece with a characteristic wing and is fitted with a belt to fix it to the body and other furniture. This makes the present invention a more fit to the body and an independent massage device.

Further, in the electric roller and massage device having the above configuration, a frame surrounding the upper edge and the left and right sides of the back base is attached, and a rotatable seat is attached to a lower end of the frame. This results in an independent chair-type massage device.
