DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show the present embodiment, FIG. 1 is a schematic sectional view of a massage machine, FIG. 2 is a schematic perspective view of a main part of a driving mechanism of the massage machine, and FIG. It is a schematic perspective view.

As shown in FIG. 1, the massage machine 1 of this embodiment includes a treatment element rotating mechanism 4 inside a backrest 3 of a chair 2.

The treatment element rotating mechanism 4 mainly includes a pair of treatment elements 10, a driving means 20 for rotating the treatment element 10,
And a guide body 30 for controlling the rotation of the treatment element 10.

As shown in FIGS. 1 and 2, the treatment element 10 is connected to one end of an arm 11 having elasticity, and the other end of the arm 11 is provided with a fixing member 22 to a rotating shaft 21. By being worn, the treatment element 10 is fixed to the rotating shaft 21 via the arm 11 having elasticity. When the rotating shaft 21 is rotated, the treatment element 10 is rotated accordingly. In this embodiment, a pair of treatment elements 10
Are mounted in such a manner that they are located in opposite directions about the rotation shaft 21 so as to rotate with a half turn from each other so that they can be beaten alternately. The rotation shaft 21 is configured to rotate in the direction of arrow A by a drive source (not shown).

As the arm 11, a wire material such as a spring having elasticity or a plate material such as a leaf spring can be used, but it is preferable to use a leaf spring having a constant bending direction as in this embodiment. desirable. The treatment child 10
As shown in FIG. 3, if the rotors 12 and 13 are connected by a support shaft 16 with bearings 14 and 15 interposed therebetween, and the arm 11 is connected to the support shaft 16, , The treatment element 10 can run smoothly, and the treatment element rotation mechanism 4 operates smoothly.

Guide body 30 for controlling rotation of treatment element 10
Is formed of, for example, a cylindrical body as shown in FIG.
The treatment element 10 is arranged in parallel with the rotation shaft 21 in the axial direction, and is configured so that the treatment element 10 rotates in the inside thereof.
That is, the guide body 30 is arranged along the orbit around which the treatment element 10 rotates. In addition, the guide body 30
As shown in FIG. 1, an opening 31 is provided on the patient side so that the pair of treatment elements 10 can project outside the guide body 30 so that the pair of treatment elements 10 can perform a beating operation. Is formed. Note that the guide body 30 does not need to be a cylindrical body as in this embodiment, and a rail-shaped guide body may be used.

When the treatment element 10 comes out, the guide body 30 uses the elasticity of the arm 11 to open the opening 31.
The distance between the rotating shaft 21 and the upper edge 32 of the opening is formed to be smaller than the length from the rotating shaft 21 to the treatment element 10 so as to protrude and rotate. With such a configuration, the treatment element 10 in the guide body 30 is bent as the arm 11 is bent toward the opening 31, and when the treatment element 10 is separated from the opening upper edge 32, the curved arm 11 Due to the restoring force, the treatment element 10 comes out so as to strongly jump out of the opening 30. This restoring force is added to the rotational force of the treatment element 10 and becomes a striking force on the patient. Then, in order to make the restoring force more than a certain strength, the treatment element 10 is moved from the upper edge of the opening after the base 11 ′ of the arm 11 reaches a line connecting the rotating shaft 21 and the upper edge 32 of the opening. 32
The rotation angle a at which the rotating shaft 21 rotates until it separates from
Set to exceed 20 degrees.

In other words, the impact force of the treatment element 10 is
The elasticity accumulated in the elastic arm 11 from when the rotating shaft 21 on which the arm 11 is mounted reaches the line connecting the rotating shaft 21 and the upper edge 32 of the opening to when the rotating shaft 21 rotates 120 degrees or more. The energy is generated by changing the kinetic energy of the treatment element 10 when the treatment element 10 is separated from the upper edge 32 of the opening.

When the rotation angle a is less than 120 degrees, the restoring force is not exerted, and therefore, the impact force of the treatment element on the patient becomes weak, and the massage effect cannot be exhibited. Further, in order to set the rotation angle a to 120 degrees or more, the selection of the material of the elastic arm and the rotation shaft 2
1 to the upper edge of the opening and from the rotating shaft 21 to the treatment element 1
This can be done by adjusting the length to zero.

With the above configuration, a constant impact force can be obtained irrespective of the rotational speed of the treatment element.

The present invention is not limited to the embodiments described above, but includes a wide range of modifications without departing from the spirit of the present invention.

[0018]

In the massage machine according to the present invention, a pair of treatment elements for performing a beating operation by a rotary motion are connected to an elastic arm, and the arm is axially mounted on a rotating shaft rotated by a driving source. The cylindrical body arranged parallel to the rotation axis and the axial direction, and configured so that the treatment element rotates inside, has an opening through which the treatment element is exposed to the outside of the cylindrical body. By making the distance to the edge smaller than the length from the rotation axis to the treatment element, the rotation axis rotated 120 degrees or more after the base of the arm reached the line connecting the rotation axis and the upper edge of the opening. Since the treatment element is later configured to separate from the upper edge of the opening, the striking force by the treatment element is rotated after the rotation axis on which the arm is pivoted reaches a line connecting the rotation axis and the upper edge of the opening. A shaft that has elasticity until the shaft rotates 120 degrees or more Elastic energy is accumulated in the arm is,
This is caused by a change in the kinetic energy of the treatment element when the treatment element separates from the upper edge of the opening.

Therefore, a constant impact force can be obtained irrespective of the number of rotations of the treatment element, so that an excellent massage effect as a beating massage machine can be expected.
