Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massaging device for massaging a user by reciprocally driving a massaging roller.

[0002]

2. Description of the Related Art Generally, in this type of massaging device, a holding body holding a massaging roller is movably provided in a base body having an upper surface opened and the opening covered with a cover. By moving the body back and forth by the driving means, the user lying on the cover is massaged by the massager roller.

The massaging device is a mattress type,
There is a chair type, and in the former case, two holding bodies are provided at a predetermined distance in the running direction, and in the latter case, one holding body is provided so as to be freely movable.

In any case, a plurality of massaji rollers are rotatably supported by the holding body at a predetermined interval in the width direction intersecting at least the running direction of the holding body. . These massile rollers run while pressing both sides of the user's dorsal spine and legs.

By the way, the user's back and legs pressed by the massa-gi-roller are not flat but curved surfaces in the lateral width direction and the length direction. Especially, the curve from the waist to the buttocks. The degree is higher than other parts. The portion thus curved to the above holding body,
When massaging is simply done by a rotatable massa-gi-lora, only a part of the massa-gi-raola hits the back of the user strongly and the rest of the massa-gi-lora hardly hits. There is something like this.

Therefore, for example, the massager roller does not reliably hit the waisted portion, the recessed portions on both sides of the spine, or the curved leg portion with a predetermined pressing force, so that a sufficient massage effect is obtained. Not only that, but the massager girola hits the protruding part too strongly and causes pain.

[0007]

As described above, in the conventional massaging device, since the massaging roller is simply rotatably provided on the holding body, the massaging device is provided with respect to the curved shape of the back surface of the user. However, there are some cases where a good massaging effect cannot be obtained because it may be hit too strongly or may not hit sufficiently.

The present invention has been made in view of the above circumstances. An object of the present invention is to make it possible to reliably massage a curved back surface of a user with substantially uniform strength. To provide a device.

[0009]

A first means of the present invention is to provide a base body, a holding body which is provided so as to be movable along a predetermined direction of the base body, and the holding body along a predetermined direction of the base body. Driving means for reciprocating, a massaging roller provided on the holding body so as to be swingable both in the traveling direction and in a direction intersecting the traveling direction, and at least the massing giro of the base body. -A cover covering the surface on which the la is provided.

A second means of the present invention is a base body, and a holding body which is provided so as to be movable along a predetermined direction of the base body and which has a support shaft laid along the width direction of the base body. Driving means for reciprocally driving the holding body along a predetermined direction of the base body, a roller support provided on a supporting shaft of the holding body so as to be swingable about the supporting shaft, and the roller supporting body. The la supporter is provided with a masser roller that is swingable in both the traveling direction of the holding body and a direction that intersects the traveling direction, and the masser roller of the base body. It is characterized in that it has a cover covering the surface.

[0011]

According to the above-mentioned first means, since the massaji roller can be swung with respect to the holding body in the traveling direction and in the direction intersecting with the holding body, it can be adapted to the curved shape of the back surface of the user. The massa-gi-roller rocks. Therefore, the back surface of the user is surely massaged by the massage roller with a substantially uniform pressing force.

According to the second means, the mass giro-
The roller is swingable with respect to the holding body in the traveling direction and in a direction intersecting the direction, and the roller support body provided with a massaging roller also swings with respect to the support shaft of the holding body. Since it is movable, the massaji roller easily swings even with respect to a slight curved shape of the back surface of the user. Therefore, the user's back is surely and satisfactorily massaged.
