Abstract

PURPOSE:To provide a massaging unit having massaging sections which hardly wedge into the human body and giving a sufficient massage effect by forming the contact parts, making press-contact with the human body to be massaged, of the massage sections, which are opposed to each other in the direction of the center axes thereof, in such a shape that the further the radial distance from their axes, the longer the distance between the contact parts becomes. CONSTITUTION:The contact parts, making contact with the human body, of two massaging sections 19, 19 which are opposed in the directions of the center axes P are formed in such a shape that the further the radial distance from their axes, the longer the distance therebetween becomes. When the two massaging sections 19, 19 are made to contact with the human body, they approach together so as to make press-contact with the human body in the direction of the axes P, the slide on the human body along the two massaging sections 19, 19 is always directed radially from the axes P, no parts of the human body wedge between the parts, making contact with the human body, of the two massaging sections 19, 19. With this arrangement, it is possible to sufficiently make press-contact with the two massaging sections 19, 19, thereby it is possible to obtain a sufficient massage effect.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a frame in which a pair of massaging bodies for sandwiching and massaging a portion to be pine surged are integrally driven and rotated around the same axis. The present invention relates to a pine surge machine in which a massaging section is formed in each of the massaging bodies, and the distance between the portions facing each other in the axial direction gradually becomes smaller as the massaging body moves around the axial center.

[Prior Art] Conventionally, in the above-mentioned pine surge machine, each of the pair of massaging bodies is formed from a disk, and the pair of disks are aligned with respect to the axis so that they are plane symmetrical. supported by the frame in an inclined state, and
The rubbing portion was formed by an annular roller pad provided on the outer periphery of these disks. By tilting the disk forming the massaging body, adjacent parts are formed on both massaging surfaces facing each other in the axial direction, where the distance between them decreases as the distance from the axial center increases in the radial direction. Ta. (For example, see Utility Model Application Publication No. 1-98629).

[Problems to be Solved by the Invention] However, according to the above-mentioned conventional structure, during the massaging pine surge, the proximate portion of the massaging portion digs into the human body, which is the body subject to the pine surge, at an acute angle and pinches the body. Because it was too dense, there was a risk that the person using it 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 too strong.
There was a risk that the pine surge effect would be insufficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pine serge machine whose massaging portion does not easily dig into the human body and can provide a sufficient mass pine surge effect.

[Means for Solving the Problems] In order to achieve the above object, the first characteristic configuration of the pine surge machine according to the present invention is that the pine surge body contact portions facing each other in the axial direction of each of the two massaging portions, The reason is that the distance between them increases as the distance from the axis increases in the radial direction.

Also, preferably, a second characteristic configuration of the present invention is that in the first characteristic configuration, both the massaging parts are constituted by a plurality of rollers whose rotation axes are oriented in a radial direction from the axis. be.

[Function] According to the first characteristic configuration of the present invention, FIGS.
As shown in the figure, both the massaging parts (19).

When a human body is brought into contact with (19), the massaging parts (19) and (i9) come close to each other and press the human body in the direction of the axis (P) as the pine surge machine is driven.

However, since the sliding direction of the human body along each of the massaging portions (19), (19) is always in the radial direction from the axis (P), the massaging portions (19), (19)
) The human body will not get wedged between the contact parts of 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), fine adjustment of the massaging pine surge effect can be performed appropriately.

Further, according to the second feature of the present invention, as shown in FIG. 4, the plurality of rolling elements (18) sequentially contact the human body, so that a more varied pine surge effect can be obtained. Can be done. Moreover, with the first characteristic configuration, it is possible to prevent the human body from digging into the massaging portions (19).
, (19), there is no danger that the human body that is wedged between them will be suddenly pressed against the rolling elements (18).

[Effects of the Invention] As described above, according to the present invention, it has become possible to provide a pine surge machine whose massaging portion is difficult to dig into the human body and which can obtain a sufficient massing pine surge effect.
