Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a pine surge device for performing pine surgery on the feet of a user.

(Prior Art) There are various types of pine surgery devices, one of which is one that performs pine surgery on the user's feet.

Conventionally, in this type of pine surge device, a flat plate-shaped vibrating body is provided substantially horizontally on the upper surface side of a device main body in which a vibration generating mechanism is built-in. This vibrating body has a large number of protrusions projecting from its upper surface, and is configured to be vibrated by the vibration generating mechanism. Therefore, by sitting on a chair and placing their feet on the vibrating body, the user can receive a pine surge on the soles of their feet.

A large number of protrusions are provided on the upper surface of the vibrating body to enhance the pine surge effect. When providing a protrusion, rather than the protrusion being hard,
The pine surge effect given to the user is better if it has a certain degree of elasticity. Therefore, in the past, projections were integrally formed on a rubber plate, and the rubber plate was adhered to the upper surface of the vibrating body using an adhesive.

However, with such a configuration, when the vibrating body is vibrated by placing the foot on the rubber plate in order to receive the pine surge, shearing force is generated between the joint surfaces of the rubber plate and the vibrating body. A rubber plate simply bonded to the top surface of the vibrating body with an adhesive tends to peel off from the vibrating body after repeated use.

(Problems to be solved by the invention) As described above, in the conventional pine surge device, a rubber plate having projections to enhance the pine surge effect was attached to the top surface of the vibrating body with adhesive.
It was found that it was easy to peel off after long-term use.

This idea was made based on the above circumstances, and its purpose is to prevent the rubber plate from peeling off when a rubber plate with protrusions is provided on the top surface of the vibrator to enhance the pine surge effect. An object of the present invention is to provide a foot pine surgery device.

[Structure of the idea]

(Means and effects for solving the problem) In order to solve the above problem, this invention includes a main body, a vibration generating mechanism built in the main body, and a vibration generating mechanism provided on the upper surface side of the main body. The vibrating body is equipped with a vibrating body that is vibrated by a rubber plate, and a rubber plate having a large number of protrusions formed by injection molding thermoplastic elastomer on the top surface of the vibrating body. The vibrator is characterized in that a through hole is formed for forming a caulking part for flowing the thermoplastic elastomer to the back side and fixing the rubber plate to the vibrating body.

According to such a configuration, the rubber plate is connected to the vibrating body by the caulking part that is integrally formed with the rubber plate, so even if there is a misalignment between the rubber plate and the vibrating body, separation will not occur. It's embarrassing.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 6. The foot vibrating pine surgery device shown in FIG. 1 includes a main body 1. Leg members 2 are attached to each of the four corners of the bottom of the main body 1,
Further, the upper surface is formed into an inclined surface 3 inclined at a predetermined angle. A through hole 4 is bored approximately in the center of the inclined surface 3, and a motor 6 constituting a vibration generating mechanism 5 is provided in the main body 1 facing the through hole 4. A rotating shaft 7 of this motor 6 protrudes from the through hole 4, and a rotating body 8 is eccentrically attached thereto. In other words, the rotating body 8 includes a balancer 8a and a shaft portion 8b projecting from the upper surface of the balancer 8a, and the shaft portion 8b is eccentric with respect to the rotating shaft 7. Then, the shaft portion 8b
A radial bearing 9 is fitted onto the radial bearing 9, and the radial bearing 9 is fitted onto a vibrating body 11 disposed above the inclined surface 3 of the main body 1. That is, the vibrating body 1
A cylindrical mounting portion 12 is provided vertically at the center of the inner surface of the bearing 1, and the radial bearing 9 is fitted into this mounting portion 12. Therefore, when the motor 6 operates, the vibrating body 11 is caused to vibrate in a plane direction perpendicular to the axis of the rotating shaft 7 by the shaft portion 8b of the rotating body 8 which rotates eccentrically.

The vibrating body 11 has first connecting portions 13 recessed in its four corners, and a second connecting portion 14 is provided on the inclined surface 3 of the main body 1 corresponding to the first connecting portions 13. It is recessed. Each of the corresponding first connecting portions 13 and second connecting portions 14 is connected by an elastic material 15 such as rubber. That is, screws 16 are embedded in both ends of the elastic material 15, and the screws 16 are inserted into through holes 17 formed in each of the connecting parts 13 and 14, and the nuts 18 are screwed therein. Therefore, the elastic material 15 is attached. Therefore,
The vibrating body 11 vibrates while elastically deforming the elastic members 15, and the vibrating body 11 is held by these elastic members 15 so that the mounted state does not tilt.

Further, the vibrating body 11 has a corner portion at its upper end in the inclination direction formed into a rounded curved surface portion 19, and a convex portion 21 having an arcuate cross section along the width direction is formed in the middle portion. There is. A rubber plate 22 is bonded and fixed to the vibrating body 11 over its upper surface and the curved surface portion 19 on the upper end side in the inclined direction. This rubber plate 22 has a large number of hemispherical protrusions 2.
3 is provided in a protruding manner, and a projection 23a that is sufficiently larger than the projections 23 in other parts is formed at a location corresponding to the top of the projection 21.

The vibrating body 11 is molded from ABS resin,
The rubber plate 22 is made of thermoplastic elastomer. That is, the rubber plate 22 is formed by injection molding a thermoplastic elastomer onto the upper surface of the vibrating body 11. At that time, vibrator 1
The thermoplastic elastomer flows to the lower surface side from the plurality of through holes 11a drilled in the vibrating body 11 and hardens into a caulked portion 22a larger than the through holes 11a, thereby allowing the rubber plate 22 to be attached to and detached from the vibrating body 11. It is bonded and fixed to.

A switch 24 is provided on the upper surface of the main body 1 on the lower end side in the direction of inclination. The switch 24 can turn on/off the motor 6 and adjust the strength of rotation. In addition, in Fig. 1, 25 is a power cord, 2
6 is a frequency selection switch, 27 is a wiring cord,
28 is a printed circuit board.

On the other hand, the leg member 2 is constructed as shown in FIGS. 2 and 3. That is, the leg member 2 is formed by integrally molding a cylindrical base 29 and a cylindrical connecting part 31 having a smaller diameter than the base and protruding from the upper surface of the base 29 from an elastic material such as rubber. . The base 29 has first to fourth annular walls 32a to 32.
d are formed by first to fourth grooves 33a to 33d that are open to the lower end surface of the base portion 29, respectively. Regarding the length of these annular walls, the first annular wall 32a located at the outermost periphery is the longest, followed by the second annular wall 32b, the third annular wall 32c, and the fourth annular wall 3.
The order is 2d. Therefore, although the lower end surface of the first annular wall 3a of the leg member 2 is normally in contact with the ground, when the load applied thereto increases and the leg member 2 is compressed and deformed, the second to fourth annular walls 3a The annular walls 32b to 32d are grounded in sequence, increasing ground resistance. A fifth groove 33e is formed on the outer periphery of the connecting portion 31 in the base 29 and is open to the upper surface side of the base 29, and this groove 33e makes it easier for the fourth annular wall 32d to displace. There is. Further, among the annular walls, the first annular wall 32a is formed to be the thinnest, and the fourth annular wall 32d is formed to be the thickest.

Further, an annular groove 34 is formed in the connecting portion 31 in the circumferential direction thereof. Then, the leg member 2 is attached by fitting the connecting portion 31 into the mounting hole 35 bored in the bottom surface of the main body 1, and engaging the annular groove 34 with the peripheral part of the mounting hole 35 of the main body 1. There is.
Therefore, the leg member 2 receives the load of the main body 1 and the vibrating body 11.

The foot massage device constructed in this manner is utilized as shown in FIGS. 4 to 6. That is, as shown in FIG. 4, when the user U is seated on the chair 41 and presses the soles of his feet against the rubber plate 22 of the vibrating body 11, he can receive a pine surge there. Furthermore, as shown in FIG. 5, if the foot is thrown out from the almost perpendicular position shown in FIG. You can receive pine surge in this area.

When receiving the pine surge in this way, the vibrating body 11 is inclined at a predetermined angle, and the upper end in the direction of inclination is formed into the curved surface part 19, so that the user U
The user can press the Achilles tendon portion against the curved surface portion 19 and receive a pine surge on that portion by simply throwing out the foot without taking an unreasonable posture.

In addition, since a convex portion 21 is formed in the central portion of the vibrating body 11, this portion can be used to receive the pine surge on the arch of the foot, and the large protrusion 21 can be used to
You can do things like press the base of your toes against a and receive a pine surge on this area.

Furthermore, as shown in FIG.
If you get off the train and place your calf part on the vibrating body 11, you can receive a pine surge on that part.

In addition, if the user wants to receive strong pine surge in each of the above-mentioned modes, if the user operates the switch 24 to increase the rotation speed of the motor 6, the vibrating body 11 will vibrate at a high frequency, so that the user can Can receive strong pine surge. In this way, when the rotational speed of the motor 6 is increased and the frequency of vibration of the vibrating body 11 is increased, the main body 1 becomes more likely to shift. However, at that time, the user strongly presses his/her foot against the vibrating body 11 in order to experience strong vibrations. Then, the load acts on the leg member 2 as a compressive load and elastically deforms the base 29, so that the number of annular walls that the base 29 contacts with the ground increases. For example, previously only the first annular wall 32a and the second annular wall 32b were grounded, but now the third annular wall 32c and the fourth annular wall 32d are also grounded. As a result, the ground resistance of the leg members 2 increases, so that even if the vibration of the pine surge device is strengthened, the main body 1 becomes difficult to shift. Therefore, the user U can receive the strong pine surge in good condition.

Further, the rubber plate 22 provided on the upper surface of the vibrating body 11 has a through-hole 11a formed in the vibrating body 11.
, a caulking portion 22a integrally formed on the rubber plate 22
The connection is fixed by combining the . Therefore, even if a shearing force is generated between the vibrating body 11 and the rubber plate 22 by vibrating the vibrating body 11, the caulked portion 22a elastically deforms and absorbs it. That is, even if a shearing force is generated between the rubber plate 22 and the vibrating body 11 as in the conventional case where the rubber plate 22 and the vibrating body 11 are attached with an adhesive, the rubber plate 22 will not easily peel off from the vibrating body 11.

In the above embodiment, the rubber plate 22 is used to form the projections 23 on the upper surface of the vibrating body 11 and the curved surface portion 19.
However, the vibrating body 11 may be molded from synthetic resin or the like, and the protrusions 23 may be integrally molded at that time.

Further, instead of an annular wall, the leg member 21 has a conical surface 51 on the lower surface of its base 29 that becomes higher toward the center in the radial direction, as shown in FIG.
Even with such a structure, if the load applied to the base 29 increases, the ground contact area of the conical surface 51 increases, so that the ground resistance of the leg member 2 can be increased.

[Effect of idea]

As mentioned above, this invention is achieved by injection molding thermoplastic elastomer on the upper surface of the vibrating body with a through hole, which has a large number of protrusions and a caulking structure that protrudes from the through hole to the back side of the vibrating body. A rubber plate is provided which is integrally connected to the vibrating body at some parts.

Therefore, even if a shearing force is generated between the vibrating body and the rubber plate by vibrating the vibrating body, the caulked part elastically deforms and absorbs it. The plate is difficult to separate from the vibrating body.
