Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a pine surgery machine, particularly a roller-type pine surgery machine for performing pine surgery on calves.

[Background Art] For example, there is a device that performs pine surgery on the calf using a rotating roller, as shown in Japanese Utility Model Publication No. 10799/1983. A large number of annular protrusions are provided in the annular recess to provide stimulation to the calves by providing an annular shape on the outer peripheral surface of the recess so that the calf can be received in a stable manner. However, this product has many annular protrusions, so the force is dispersed.
On the contrary, the stimulation was weak and it was not possible to apply effective pine surge to the calves.

[Purpose of the invention] The present invention has been devised in view of the above points, and its purpose is to provide a pine surge machine that can provide stimulating and effective pine surgery to the calves. .

[Disclosure of the invention] Accordingly, the present invention provides a pair of annular recesses that match the cross-sectional shape of the calf at intervals in the axial direction on a rotating roller, and a pair of large-diameter annular protrusions between both annular recesses. The feature is that a small-diameter annular protrusion is provided at the center of each annular recess that smoothly connects with the annular recess, and the small-diameter annular protrusion provides reliable stimulation to the calf. This is how it was done.

The present invention will be described in detail below based on the illustrated embodiment.The present invention will be described in detail as follows. A plurality of rollers 1 are housed in a rectangular housing 4. The drive shaft 3 is disposed on one side of the housing 4, and a worm wheel 25 is fixed to one end of the drive shaft 3. The rotation of the motor 2 is controlled by a pair of pulleys 21 and 23 connected by a belt 22, and a worm 24, to which the pulley 23 is fixed at one end and meshes with the worm wheel 25 in a gearbox 26.
is transmitted to.

As shown in FIG. 4, the plurality of rollers 1 arranged at equal intervals around the drive shaft 3 are each formed of a shaft 10 made of a pipe and a roller body 11 placed over the shaft 10. and both ends of it are connected to the drive shaft 3.
It is rotatably held by a pair of plates 30, 30 attached to the . In the figure, 15 is a cap that covers both ends of the roller 1.

Here, the top corner of the housing 4 on one side where the rollers 1 are arranged is an opening and is covered with a protective fabric 40 . Further, the housing 4 is attached with a U-shaped leg 5 whose both ends are rotatably connected to the housing 4, as shown in FIGS. 7, 8, or 10. Furthermore, by changing the angle of the legs 5 with respect to the housing 4, the inclination of the housing 4 can be adjusted. In the figure, 41 is a groove serving as a handle.

However, in this pine surge machine, the drive shaft 3 is rotated by the motor 2, which causes the plurality of rollers 1 to rotate around the drive shaft 3. The rollers 1 perform pine surge on the back side, etc., and the roller body 11 of each roller 1 is formed with two annular recesses 12, 12 spaced apart in the axial direction, as shown in FIG. At the same time, a pair of large diameter annular protrusions 13,
13 are provided at intervals, and further each annular recess 1
A small-diameter annular protrusion 14 is provided at the center of each of the annular recesses 12 and 12, and as is clear from FIG. Small diameter annular protrusion 1
It is said that it smoothly connects to 4.

Therefore, as shown in Figures 7 and 8, while sitting on a chair. When the calf is placed against the roller 1 through the cloth 40, as shown in FIG.
As the calf settles down in the annular recess 12,
A small-diameter annular protrusion 14 is located directly below the calf, and the annular protrusion 14 provides strong stimulation to the calf. Further, here, since the plurality of rollers 1 rotate around the drive shaft 3, stimulation to the calf is also given by the change of the rollers 1 in contact with the calf.

As shown in FIG. 10, when the sole of the foot is placed on the roller 1, the sole of the foot is placed on the large diameter annular projection 13 as shown in FIG. 11, or the small diameter annular projection 13 as shown in FIG. Depending on whether you hit part 14, you can choose whether the strength is strong or weak. Further, as shown in FIG. 13, if you press your back against the housing 4 and place both arms along your body on the annular protrusion 14 side of each annular recess 12, the large diameter annular protrusion 13, Number 13 corresponds to the position where there are many ``pressure points'' on both sides of the spine.

[Effects of the invention] As described above, in this invention, an annular recess that matches the cross-sectional shape of the calf is provided, and a small-diameter annular protrusion that smoothly connects to the annular recess is provided at the center of the annular recess. If you place your calf in the annular recess, the calf will fit comfortably into the annular recess, and the small diameter annular protrusion that is located within the annular recess and smoothly connects to the annular recess will provide reliable stimulation to the calf. It provides a good pine surge effect, and since a large diameter annular protrusion is provided between the two concave portions spaced apart in the axial direction, the roller can also be applied to the soles of the feet. When performing pine surge, the strength can be adjusted by selecting a large-diameter annular protrusion and a small-diameter annular protrusion.
