Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pine surge machine. More specifically, a pair of pine serge bodies each having a cylindrical rotation locus and a plurality of concavities and convexities on the outer periphery are arranged concentrically.
Each is supported by a frame so as to be rotatable around a drive axis along its longitudinal direction, and a pair of massaging bodies is provided between the two pine serge bodies, and the massaging parts of each of the massaging bodies are mutually rotated around the drive axis. This invention relates to pine surge machines that are arranged relative to each other so as to gradually approach and separate from each other along.

[Prior Art] Conventionally, in the above-described pine surge machine, a rod-shaped rolling element having a large-diameter portion at least at one location in the longitudinal direction and rolling around the axis of the rod-shaped rolling element, the longitudinal direction of which is driven by the A large number of discs are arranged around the drive axis along the axis to form the pine surge body, and two symmetrically inclined disks are eccentrically arranged with respect to the drive axis to form the pine surge body. The above-mentioned pair of massaging bodies were formed by protruding from the outer periphery of each pine serge body (for example, Utility Model Publication No. 1-98629
(see publication).

[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, since the pair of massaging bodies largely protrudes from the outer periphery of the pine massage body, for example, when massaging the nape of the neck and simultaneously massaging the shoulders, As mentioned above, it has been impossible to perform both the rolling pine serge using the pine surge body and the massaging pine surge using the massaging body at the same time. That is, according to the conventional state of the art, it has been determined that in order to perform massaging and pine surge most efficiently, it is best to operate the massaging body by locally pressurizing it, and therefore the conventional configuration is not as described above. It was.

Further, in the above conventional configuration, the large diameter portions between every other rolling element in the circumferential direction of the drive shaft are arranged at the same position with respect to the drive shaft direction. Therefore, when rolling pine surge is performed, the large diameter portion of the pine surge body contacts only limited positions, making it impossible to obtain a wide and uniform pine surge effect.

Furthermore, although the massaging body protrudes from the outer peripheral portion of each of the pine serge bodies, it is not supported in any way in the direction of the drive shaft center, so when the massaging body is used, the drive shaft It is easy to bend in the direction of the core, making it difficult to obtain a sufficient massaging effect, and also placing a heavy burden on the entire device, resulting in problems in its durability.

An object of the present invention is to provide a pine surge machine that is highly durable while providing variable pine surge effects, and that is capable of simultaneously performing both rolling pine surge using the pine surge body and massaging pine surge using the massaging body. There is a particular thing.

[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 a pair of pine surge bodies each having a cylindrical rotation locus and having a plurality of irregularities on the outer periphery. are arranged concentrically and supported by a frame so as to be rotatable around drive axes along the longitudinal direction, a pair of massaging bodies are provided between the two pine serge bodies, and a massaging portion of each of the massaging bodies is provided. are arranged relative to each other so as to gradually approach and separate from each other along the drive axis, the massaging body and the pine surge body are disposed on the same axis, and the massaging body and the massaging body The reason lies in that the outer circumferential portion of the pine serge body is formed flush with or substantially flush with.

Also, preferably, the second characteristic configuration of the present invention is:
In the first characteristic configuration, a rod-shaped rolling element having a large diameter portion at at least one location in the longitudinal direction and rolling around the axis of the rod-shaped rolling element is arranged such that the longitudinal direction thereof is along the drive axis. A large number of the pine surge bodies are arranged around the drive shaft core, and each of the large diameter portions between the rolling elements adjacent to each other in the circumferential direction of the drive shaft core and between every other rolling element are This is because they are arranged at different positions with respect to the direction of the drive shaft.

Furthermore, desirably, a third feature of the present invention is that in the first or second feature, the force acting on the massaging body in the direction along the drive axis is supported by the rolling element. It is in.

[Operation] According to the first characteristic configuration of the present invention, as shown in FIGS. 1 and 4, a pair of pine serge bodies 6, each having a cylindrical rotation locus and having a plurality of concavities and convexities on the outer periphery, are provided. 6 are arranged concentrically, and each frame 2 is rotatably driven around a drive axis P along its longitudinal direction.
Since the pine surge bodies 6 are supported by the pine surge bodies 6, rolling pine surge can be performed by driving and rotating the pine surge bodies 6, 6 with the unevenness of the outer periphery thereof. Moreover, a pair of massaging bodies 8, 8 are provided between the two pine serge bodies 6, 6.
In addition, since the massaging parts 17, 17 of the massaging bodies 8, 8 are arranged relative to each other so as to gradually approach and separate from each other along the drive shaft center P, the massaging bodies 6, 6 Along with the rotation, the pair of massaging bodies 8, 8 move toward and away from each other with respect to the direction of the drive shaft center P, and a massaging body can be performed between these pair of massaging parts 17, 17. can. Then, the massaging bodies 8, 8 and the pine serge bodies 6, 6 are arranged on the same axis, and the outer periphery of the massaging bodies 8, 8 and the outer periphery of the pine surge bodies 6, 6 are flush with each other. Or, since they are formed almost flush, for example, the nape of the neck can be rubbed by the pair of massaging parts 1.
If it is located between 7 and 17, this massaging part 17,
17, while massaging the nape of the neck, it is possible to perform rolling pine surgery on the shoulders that contact the pine surgery bodies 6, 6 at the same time. At this time, since it is possible to distribute the load of the body weight on the pine surge machine 1 not only to the massaging bodies 8, 8 but also to the pine surge bodies 6, 6, the burden on the pine surge machine 1 as a whole is reduced. small. Therefore, it is possible to strongly press the body against the massaging parts 17, 17 and obtain a sufficient massaging effect. Moreover, as the massaging bodies 8, 8 rotate, the unevenness of the outer peripheral portions of the pine serge bodies 6, 6 are alternately located in the vicinity thereof, so that the massaging bodies 8, 8 and the pine serge bodies 6, 6 are alternately located in the vicinity thereof.
Since the effects of both the rolling pine surge and the massaging pine surge can be obtained alternately at the boundary between the pine surge and the pine surge, it is possible to obtain a complex pine surge effect with a rich variety that has not been seen before.

According to the second feature of the present invention, the rod-shaped rolling element 15, which has the large-diameter portion 14b at at least one location in the longitudinal direction and rolls around its axis, is arranged such that the longitudinal direction thereof is Since the pine surge bodies 6, 6 are arranged in large numbers around the drive axis P in a state along the drive axis P, rolling pine surge can be smoothly caused by the rolling of the rolling member 14. It can be carried out. Further, the rolling member 1
Since the large diameter portion 14b of No. 4 can be locally pressed against the human body, the efficiency of the pine surge can be improved. Moreover, the rolling elements 15 adjacent to each other in the circumferential direction of the drive shaft center P and every other rolling element 15
Since the large diameter portions 14b between the two are arranged at different positions with respect to the drive axis P direction, the large diameter portions of the rolling member 14 are arranged at different positions with respect to the drive axis P direction. 14b can be brought into even contact with each part of the human body, and an even rolling pine surge effect can be obtained.

Furthermore, according to the third characteristic configuration of the present invention, the drive shaft core P acting on the massaging bodies 8, 8
Since the rolling elements 15 support the force in the direction along the rolling elements 15, even if a force acting in the direction of the drive axis P due to the massaging body 8 is applied to the massaging bodies 8, 8, the force is transferred to the rolling body 15. The load can be borne by the moving body 15, and the bending of the massaging bodies 8, 8 is also small.
Therefore, it is possible to sufficiently perform a strong massaging pine surge body without separately providing a special reinforcing member or the like to the device.

[Effects of the Invention] As described above, according to the present invention, it is possible to obtain a variable pine surge effect while having high durability, and
It has now become possible to provide a pine surge machine capable of simultaneously performing both rolling pine surge using the pine surge body and massaging pine surge using the massaging body. In addition, by eliminating extremely protruding parts and keeping the entire machine compact, the handling of the pine serge machine has been improved, and since both rolling pine surge and massaging pine surge can be performed at the same time, it is possible to expand its uses. It became.

By non-rotatably supporting the massaging unit 3, the massaging unit 3 is configured to be rotatable around the drive axis P of the drive shaft with respect to the frame 2.

As shown in FIGS. 1, 2, and 4, the cylindrical body 7 is provided with circular intermediate flanges 12a, 12a.
A first cylindrical member having circular end flanges 11a, 11a on both ends thereof is fitted onto the second cylindrical member 12, 12 having circular end flanges 11a, 11a on both ends. 11,11
are fitted externally. Here, the intermediate flanges 12a, 12a are formed to be inclined with respect to the drive shaft center P, and the end flanges 11a, 11a are formed to be perpendicular to the drive shaft center P. To form each of the pine surge bodies 6, 6, a rod-shaped rolling element 15 having a large diameter portion 14b at at least one location in the longitudinal direction and rolling around its axis is driven in the longitudinal direction. A large number of rolling elements 15 are arranged around the drive axis P in a posture along the axis P, and both ends of each of these rolling elements 15 are connected to the end flanges 11a, 11a and the intermediate flange 12.
a and 12a, respectively, so that its rotation locus is cylindrical, and its outer circumferential portion is provided with a plurality of projections and depressions. Further, the intermediate flanges 12a, 12a are symmetrical with respect to a plane perpendicular to the drive axis P so that they gradually approach and separate from each other around the drive axis P. They are placed relatively.

Each of the rolling elements 15 has each end flange 11
A rolling member 14 is pivotally supported on a shaft 13 whose both ends are supported by intermediate flanges 12a, 11a and 12a. Each of these rolling members 14 has a tubular portion 14
It is formed in a shape with a large diameter part 14b that gradually expands and contracts in diameter in a part of a, and when rotating around the shaft body 13, the pressing force is concentrated on the large diameter part 14b to create a strong force. It is designed to produce a pine surge effect. Each of the large diameter portions 14b has a shape obtained by rotating a convex elliptical surface around the shaft 13, and the rolling member 14 is made of a material that has a small coefficient of friction with the shaft 13. It uses synthetic resin. The large diameter portion 14b of the rolling member 14 can be brought into equal contact with each part of the human body at each position with respect to the direction of the drive axis P,
In order to obtain an even rolling pine surge effect, the rolling elements 15 adjacent to each other in the circumferential direction of the drive shaft core P and every other rolling element 1
The large diameter portions 14b between the two large diameter portions 14b are arranged at different positions with respect to the drive axis P direction. The large diameter portions 14b may be formed at two or more locations on one rolling member 14, but the intermediate flanges 12 may be formed at every other rolling member 15.
At least one is arranged close to the massaging bodies 8, 12a, and the pine surge effect near the boundary with the massaging bodies 8, 8 is varied.

As shown in FIGS. 1 and 2, the massaging bodies 8, 8 are made by protruding rubber massaging parts 17, 17 on the periphery of a disc-shaped plate material 16 having a through hole 16a in the center. It becomes. Moreover, the second cylindrical members 12, 12
A third cylindrical member 18 is provided between them to define the interval between the intermediate flanges 12a, 12a. Then, the through holes 16a of the plate material 16 are inserted into both ends of the third cylindrical member 18, and
An annular slide collar 18 is provided between the through hole 16a and the through hole 16a.
A is interposed so that each plate material 16 can be smoothly rotated even when a load is applied to the massaging portions 17 in the radial direction. On the other hand, each of the plates 16 can be rotated smoothly even when the massaging portions 17, 17 are loaded in the thrust direction, and the weight is borne by the shaft 13, thereby improving the durability of the entire device. , each of the plate materials 1
A flat annular resin plate 18b is interposed between the intermediate flanges 6 and 16 and each of the intermediate flanges 12a and 12a. Further, the outer peripheries of the massaging bodies 8, 8 and the outer peripheries of the pine surge bodies 6, 6 are formed to be flush or substantially flush in the direction along the drive axis P. Specifically, the diameter of the plate material 16 is formed to be approximately equal to the diameter of the inclined intermediate flanges 12a, 12a, and the outer periphery of the massaging portions 17, 17 in the radial direction is formed to be approximately equal to the diameter of the inclined intermediate flanges 12a, 12a. It is set at approximately the same height as the large diameter portion 14b of the rolling element 15.

Next, a method of using the pine surge machine 1 configured as described above will be explained.

For example, when performing pine surgery on the nape of the neck and shoulders at the same time, the nape of the neck is positioned between the massaging bodies 8, 8, and the shoulders are brought into contact with the pine surgery bodies 6, 6 through the cover 4. . Then, by driving and rotating both the pine surge bodies 6, 6, rolling pine surge can be performed using each large diameter portion 14b of the rolling member 14. Since both the massaging bodies 8, 8 take the same movement locus as the inclined intermediate flanges 12a, 12a in the direction of the drive axis P, the massaging bodies 8, 8 move along the rotation of the pine surge bodies 6, 6. The bodies 8, 8 perform distance movement relative to each other in the direction of the drive axis P, and massage can be performed between the massaging portions 17, 17 of these massaging bodies 8, 8. Moreover, as the massaging bodies 8, 8 rotate, the large diameter portions 14b of the outer circumferences of the pine serge bodies 6, 6 are alternately located in the vicinity thereof, so that the massaging bodies 8, 8 and the pine serge body At each boundary between 6 and 6, the effects of rolling pine surge and massaging pine surge can be obtained alternately, so it is possible to obtain a complex pine surge effect that is rich in variation. In addition, since the rolling member 14 and the massaging bodies 8, 8 can rotate relative to the pine surge bodies 6, 6, even if the body is strongly pressed against these parts, the rolling member 14 and the massaging bodies 8, , 8 are not caught by the cover, the massaging unit 3 can be driven and rotated smoothly.
Also, as a matter of course, the pine serge bodies 6, 6
It is also possible to use the massaging bodies 8 and 8 alone.

(a) In the above embodiment, the unevenness on the outer circumference of each of the pine surge bodies 6, 6 was formed by the rolling member 14 pivoted on the shaft body 13, but the unevenness was formed by a rolling member 14 rotatable along a spherical surface. It may be formed by a ball or a concave-convex curved surface that is fixed to the cylindrical body 7.

(b) In the above embodiment, the massaging bodies 8, 8
is composed of a disk-shaped plate arranged in an inclined posture with respect to the drive axis P, but it is sufficient to arrange the plates so that they move toward and away from each other in the direction of the drive axis P, and the plates are not necessarily inclined. There is no need to set it up.

(c) In the above embodiment, each of the large diameter portions 14
b was configured to have a shape obtained by rotating a convex elliptical surface around the shaft 13, but it is also possible to make a shape obtained by rotating a gourd-shaped surface around the shaft 13, etc.
