Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a pair of massaging bodies that sandwich and massage a portion to be pine surged, which are provided so as to be freely driven and rotatable about the same axis; The present invention relates to a pine serge machine in which a massaging portion is formed in each body, and the interval between portions facing each other in the axial direction becomes gradually smaller as the distance moves around the axial center.

[Conventional technology]

In a conventional pine surge machine, the pair of massaging bodies are fitted onto a fixed support shaft that supports them so as to be rotatable around the support shaft and slidable along the axial direction of the massaging body. The massaging body transmits a driving force from a drive mechanism to the massaging body, rotates the massaging bodies around the axis, and slides them so that the distance between them in the axial direction becomes small, thereby sandwiching the part to be pine surged. It was hot.

In addition, as a device having another configuration, a pair of massaging bodies are each formed from a disk, and the pair of disks are tilted with respect to the axis so that they are in a plane symmetrical relationship with each other, and a frame is provided. There was one in which the rubbing portion was formed by an annular roller pad provided on the outer periphery of the disk. By inclining the disk forming the massaging body, two massaging surfaces facing each other in the axial direction are provided with adjacent portions in which the distance between them decreases as the distance from the axial center increases in the radial direction. was forming. For example, see Utility Model Application Publication No. 1-98629).

[Problem to be solved by the invention]

However, according to the former conventional configuration described above, since the massaging body constantly rotates or slides with respect to the support shaft of the massaging body, there is a problem that wear due to friction between the two is severe and durability is lacking. There is.

On the other hand, according to the latter conventional configuration, during the massaging pine surge, the proximal part of the massaging section digs into the human body, which is the body to be pine surged, at an acute angle and the pinching force is too strong. There was a risk that the patient would feel pain. On the other hand, if one tries to avoid the rubbing part biting into the pine serge part, the pressure contact of the pine surge part against the pine serge part will not be very strong.
There was a risk that the pine surge effect would be insufficient.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide a highly durable pine serge machine that has a massaging section that does not easily dig into the human body, can obtain a sufficient massing pine surge effect, and is highly durable. .

[Means to solve the problem]

In order to achieve the above object, the first characteristic configuration of the pine surge machine according to the present invention is to provide a pair of massaging bodies that are integrally driven and rotatable around the same axis and that sandwich and massage the pine surge target part, and The massaging parts for contacting the pine surge body provided separately on the pair of massaging bodies are arranged so that the interval between the parts facing each other in the axis direction becomes gradually smaller as the distance moves around the axis, and the tip The two massaging bodies are formed into a substantially cone shape with the massaging bodies facing each other, and both of the massaging bodies are fixed to a rotating shaft.

Also, preferably, the second characteristic configuration of the present invention is:
In the first characteristic configuration, both the massaging parts are constituted by a plurality of rollers whose rotational axes are oriented in a radial direction from the axle.

[Effect]

According to the first characteristic configuration of the present invention, as shown in FIG. 1 and FIG. is formed so that it gradually becomes smaller as it moves around the axis P. Therefore, when a human body is brought into contact with the two massaging parts 19, 19, the massaging parts 19, 19 will gradually become smaller as the massaging parts 19, 19 are driven. The massaging parts 19, 19 are brought close to each other and press against the human body in the direction of the axis P. In addition, each of the massaging portions 1
9 and 19 are formed into a substantially cone shape with their tips facing each other in the direction of the axis P, so the shape of the contact portion of the body to be pine surged formed by both the massaging parts 19 and 19 becomes an open groove shape. Unlike conventional pine surge machines, the human body does not get stuck between the contact portions of the massaging parts 19, 19 with the pine surge body. Therefore, the human body can be brought into sufficiently strong pressure contact with the massaging parts 19, 19 without fear of the bite, and a high pine surge effect can be obtained. Moreover, by adjusting the degree of pressure applied to both the massaging portions 19, 19, the massaging pine surge effect can be finely adjusted. Furthermore, since both the massaging bodies are fixed to the rotating shaft, it is possible to prevent breakdowns due to wear between the two, and it is possible to improve the durability of the device.

Further, according to the second characteristic configuration of the present invention, as shown in FIG. 4, the plurality of rolling elements 18 contact the human body sequentially, so that a more varied pine surge effect can be obtained. . In addition, the first characteristic configuration prevents the human body from digging into the body, so there is no risk that the human body, which is wedged between the massaging portions 19 and 19, will be suddenly pressed against the rolling elements 18.

〔Effect of the invention〕

As described above, according to the present invention, the massaging portion does not easily dig into the human body, and a sufficient massaging effect can be obtained, and the durability of the device can also be increased.
