Less than,
The massage machine 3 of the present invention will be described.

The massage machine 3 is one in which a plurality of treatment elements 2 revolve around the rotary shaft 1 and the treatment elements 2 themselves rotate.

The rotating shaft 1 is provided with bearings at both ends and is rotatably supported by a mount (not shown).
A worm wheel 41, a center gear 5, and a pair of roller plates 6 are provided in this order from one end side.

The worm wheel 41 is fixed to the rotary shaft 1 by a key (not shown) and meshes with a worm shaft 42 arranged in the vicinity of the worm wheel 41. The worm shaft 42 is a driving means such as a motor. The worm wheel 41 and the rotary shaft 1 are rotated by being driven by (not shown).

The central gear 5 is rotatably provided on the rotary shaft 1 via a bearing (not shown), and is fixedly connected to the mount so as not to rotate together with the rotary shaft 1.

The roller plate 6 has a substantially disc shape, and the rotary shaft 1 is vertically inserted through the center thereof and fixed to the rotary shaft 1 with a key (not shown). The roller plate 6 is attached to each of two positions in the axial direction of the rotary shaft 1, and both ends of the roller 61 are axially supported.

The roller 61 is rotatably supported on the roller plate 6 via a bearing (not shown), that is, is rotatable about its own axis. The roller 61 is attached to the roller plates 6 on both sides. Are provided so as to overlap each other when viewed in the axial direction, and the rollers 61 are axially supported in parallel with the rotary shaft 1. It should be noted that a plurality of such rollers 61 (five in the present embodiment) are provided,
Further, in this embodiment, as shown in FIG. 1A, all the rollers 61 are arranged on the same circumference centered on the rotation axis 1 of the roller plate 6 as viewed in the axial direction.

Further, at this time, as shown in FIG. 3, all or part of the revolution direction distance between the adjacent rollers 61 may be different. That is, the rollers 61 are arranged so that the central angles formed by the adjacent rollers 61 about the rotation axis 1 are not the same. By doing so, although the rotation speed of the rotary shaft 1 is constant, the stimulus given to the human body by the treatment element 2 is not monotonous, and the feeling of massage is improved.

Such a roller 61 is provided by covering the treatment element 2 which is pressed against the treatment area of the human body, and the treatment element 2 has, for example, a wave shape in the axial direction as shown in FIG. In the present embodiment, the projections 8 are further provided at four locations on the outer circumference, so that a further pressing stimulus can be applied to the treatment site of the human body.

As described above, the end portions of the rollers 61 are axially supported by the bearings of the roller plate 6, respectively. However, in the roller plate 6 on the side where the above-described center gear 5 is provided, the end portions are roller-supported. A roller gear 62 that protrudes to the outside of the plate 6 and meshes with the center gear 5 is fixed to this end portion with a key (not shown).

The above-mentioned central gear 5 and roller gear 62
(And the roller 61) and the roller plate 6 (and the rotary shaft 1) respectively correspond to the sun gear, the planetary gear and the carrier in the planetary gear mechanism, and the central gear 5 is fixed to fix the rotary shaft 1 and the roller plate 6. By rotating, the revolving motion of the roller 61 around the central gear 5 and the revolving motion of the roller 61 (that is, rotation motion) are obtained, that is, the revolution of the treatment element 2 around the rotation axis 1 and the treatment element 2 itself. The rotation of is obtained.

At this time, the central gear 5 and the roller gear 6
By appropriately setting the tooth ratio of 2, the rotation speed ratio between the revolution and the rotation of the treatment element 2 (that is, the roller 61) can be arbitrarily set. For example, the central gear 5 and the roller gear 62. When the tooth number ratio of 1 is set to 1: 1, the treatment element 2 can be rotated twice while revolving once. However, the rotation here means the rotation of the treatment element 2 itself with respect to the gantry.

Further, as another example of the driving mechanism including the central gear 5, the roller gear 62, and the roller plate 6, the one shown in FIG. 5 will be described. In the example shown in FIG. 1, the central gear 5 (sun gear) is fixed and the rotating shaft 1 and the roller plate 6 (carrier) are rotated to rotate the roller 61 (planetary gear) around the central gear 5. In addition to the rotation of the roller 61 and the rotation of the roller 61, the center gear 5 (sun gear) is used in the example shown in FIG.
The rotational movement of the roller 61 (planetary gear) around the central gear 5 and the rotational movement of the roller 61 are obtained by independently and rotationally driving the rotating shaft 1 and the roller plate 6 (carrier) separately.

As a concrete structure, a part different from the above example will be described. First, the central gear 5 is not fixed to the pedestal by coupling, but is rotatably attached to the rotary shaft 1 and the pedestal.

A worm wheel 71 for the central gear is provided at the tip of the worm, and a worm shaft 72 for the central gear that meshes with the worm wheel 71 is provided. Then, the central gear worm wheel 71 and the central gear worm shaft 72 are driven by a driving means (not shown) such as a motor independent of the driving means for driving the worm wheel 41 and the worm shaft 42 described above. Is.

In this way, the rotation speeds of the central gear 5, the rotary shaft 1 and the roller plate 6 are set appropriately so that the treatment can be performed without changing the tooth ratio of the central gear 5 and the roller gear 62. It is possible to set the revolution and the rotation of the child 2 in arbitrary rotation directions and rotation speeds. That is, the revolution direction (normal rotation or reverse rotation) of the massaging element 2 and the number of revolutions per hour, and the rotation direction (normal rotation or reverse rotation) and the number of rotations per hour of the massaging element 2 can be arbitrarily set. At this time, it goes without saying that the revolution of the treatment element 2 can be switched between normal rotation and reverse rotation. By switching between normal rotation and reverse rotation of the revolution of the treatment element 2 in this way, the stimulation given to the human body by the treatment element 2 is not monotonous, and the feeling of massage is improved.

As shown in FIG. 4, not all the rollers 61 provided with the treatment elements 2 on the same circumference around the rotary shaft 1 in the roller plate 6 as shown in FIG. Rotation axis 1 for some rollers 61
The distance from, that is, the revolution radius is different. In the structure shown in FIG. 4 (a), it is provided at the vertices and the center of the sides of the substantially equilateral triangle when viewed in the axial direction. By doing so, although the rotation speed of the rotating shaft 1 is constant, the stimulus given to the human body by the treatment element 2 is not monotonous,
The feeling of massage is improved. In addition, FIG.
And FIG.4 (c) shows the other example of a pattern in which the revolution radius of several treatment element 2 does not become single. Even in these cases, the stimulus applied to the treatment site of the human body is similarly changed to improve the feeling of massage.

Further, it is preferable that the treatment element 2 is operated so as to repeat switching between normal rotation and reverse rotation of the revolution. By doing so, the stimulus applied to the treatment site of the human body is further changed and the feeling of massage is improved.

According to the above-mentioned structure, the treatment element 2 revolves around the rotary shaft 1 and simultaneously rotates, so that in addition to the pressing stimulus by the revolution of the treatment element 2 on the treatment site of the human body, the treatment element is also rotated. 2, the pressing stimulus due to rotation, for example, the pressing stimulus caused by the protrusion 8 provided on the outer circumference of the treatment element 2 as in the present embodiment orbiting around the treatment element 2, can be applied to the treatment area of the human body. The stimulation changes and the feeling of massage improves.

Next, still another example of the roller 61 and the roller plate 6 will be described with reference to FIG. This is to fix the two parallel roller plates 6 each of which vertically supports both sides of the roller 61 so as not to be perpendicular to the rotation axis 1, that is, the roller 61 is inclined so as not to be parallel to the rotation axis 1. It is a thing.

By doing so, the massager 2 can give a non-monotonous stimulus to the human body with a simple structure to improve the feeling of massage.

Further, as shown in FIG. 7, a plurality of treatment elements 2
A plurality of rotating shafts 1 revolving around may be provided in parallel. By doing so, for example, the rotary shaft 1 of each treatment element 2
By reversing the orbiting direction around, it is possible to apply various pressure stimuli to the human body and improve the feeling of massage.
