Description

[Detailed Description of the Invention] The present invention relates to a mechanism of a pine surger equipped with a massage ball for performing pine surgery on the nape of the neck, shoulders, etc.

Conventionally, this type of pine surge device has a basic structure as shown in FIGS. 1 and 2 of the drawings. The configuration will be briefly explained below. 1 is a drive motor; 2 is a drive motor 1
3 is a helical gear that meshes with the worm gear 2 and has a shaft 4 set at a predetermined interval; 5 is an eccentric shaft made of a coil spring or the like provided on the shaft 4 of the helical gear 3; 6 is an eccentric shaft connected to the worm gear; It is a fir ball attached to its tip. In addition, the operation is such that when the worm gear 2 is rotated by the drive motor 1, the helical gear 3 rotates in conjunction with it, and the eccentric shaft 5 performs eccentric rotation. It performs a circular motion centered on . Therefore, if you place the neck, shoulders, etc. between the fir balls 6 and 6,
Pine surgery can be performed on that area. However, in the conventional example as described above, the fir balls only move in a circular motion on the horizontal plane, so there is a problem in that it is not possible to perform a sufficiently effective pine surge by applying vibration only in the horizontal direction. Ta.

This invention was proposed to solve such problems, and without complicating the structure,
The object of the present invention is to provide a pine surge device using fir balls that is sufficiently effective.

Hereinafter, the structure and operation of the present invention that achieves the above objects will be described in detail based on the drawings showing embodiments thereof. In FIGS. 3 and 4, reference numeral 10 is a gearbox consisting of a box with a rectangular shape on the top surface, and this gearbox 10 is provided in a suitable masherage stand, but is omitted in the drawings. . Next, when showing the inside, 11 is a worm gear, and its shaft 12 has bearings 13 and 1.
4 to the gearbox 10 (FIG. 4). A pair of helical gears 15 mesh with the worm gear 11, and their shafts 16 are attached to the gear box 10 by bearings 17 and 18 on the left and right sides of the worm gear 11, respectively. In addition, the positional relationship between the helical gear 15,
15 shafts 16, 16 are arranged in such a manner that they are spread upward. 19 is gearbox 10
The shafts 16, 16 of the helical gears 15, 15
It is an eccentric shaft made of a coil spring etc. connected to the
Reference numeral 20 denotes a rice ball attached to the tips of the eccentric shafts 19, 19. Further, 31 is a drive shaft of a drive source (not shown), and this drive shaft 31 is connected to the shaft 12 of the worm gear 11 via a joint 40. In this case, if a flexible joint is used for the joint 40, flexibility can be given to the installation of the drive source and the gearbox 10.

Here, the operation of the pine surge device according to the present invention constructed as above will be explained. When the worm gear 11 rotates due to the rotation of the drive source, the rotation is transmitted to the helical gears 15, 15. As a result, when the shafts 16, 16 rotate, the eccentric shafts 19, 19 connected thereto perform eccentric rotations, so that the rice balls 20, 20 perform circular motion centered on the extension direction of the shafts 16, 16. At this time, fir ball 2
The circular motion of 0.20 is caused by the above-described configuration,
This is a circular motion with an inclination equal to the inclination of 6 and 16, and the circular motion includes a horizontal component and a vertical component. Therefore, if the user positions the nape of the neck or shoulders between the fir balls 20, 20, the circular motion of the fir balls 20, 20 can produce the pine surge effect of pushing up from below and the pine surge effect of pushing from the horizontal direction. It is something that can be obtained. Therefore, it is possible to perform a pine surge that is extremely effective compared to the conventional pine surge effect only from the horizontal direction.

Although the above-described embodiment of the present invention uses a worm gear and a helical gear, it goes without saying that the same structure can be achieved by using a bevel gear or the like, although not shown.
