Description

[Detailed Description of the Invention] Technical Field The present invention relates to a pine surge device that performs pine surge using fir balls.

Conventional technology Conventionally, a pine surger that performs pine surgery on the human body using fir balls has been designed to connect fir balls located outside the case to an eccentric joint that is connected to a drive motor provided inside the case via a transmission means such as a gear and performs eccentric movement. Generally, a seat cover is placed over the top of the rice ball. The user presses the affected part of the human body against the massaging balls through the seat cover, and obtains an acupressure effect by the eccentrically moving massaging balls. However, in the conventional pine surge device mentioned above, since the fir balls are covered with a seat cover, vibrations and abnormal noises are often generated due to friction between the fir balls and the seat cover, causing discomfort to the user. was giving. This vibration and abnormal noise are particularly noticeable when the rice balls are fixed to an eccentric joint so as not to rotate.

Purpose This invention was developed in view of the conventional problems mentioned above, and its purpose is to minimize the friction between the rice balls and the seat cover to prevent vibrations and abnormal noises. Our objective is to propose a pine surge device that allows comfortable pine surge.

Embodiment Hereinafter, the present invention will be explained in detail with reference to the drawings showing a preferred embodiment.

In FIG. 1 showing a schematic configuration of a pine surge device according to an embodiment of the present invention, 1 is a case of the pine surge device, 2 is a worm gear rotated by a drive motor (not shown) provided in the case 1, 3
-1 and 3-2 are a pair of helical gears that mesh with the worm gear 2. Helical gear 3-1, 3-
The rotating shafts 4-1 and 4-2 of 2 are each equipped with a bearing 5-
1 and 5-2, and rotates as the worm gear 2 rotates. In addition, the rotating shafts 4-1, 4-
The distance between the two helical gears 3-1 and 3-2 is determined by the diameters of the helical gears 3-1 and 3-2.

6-1 and 6-2 are eccentric joints that are connected to the tips of the rotating shafts 4-1 and 4-2 and are inclined by a predetermined angle with respect to the rotating shafts 4-1 and 4-2. It is located so as to protrude outward from the case 1. Reference numeral 7 denotes a kneading ball attached to the eccentric joints 6-1, 6-2, and the shaft 8 thereof is rotatably supported on the eccentric joints 6-1, 6-2. The massaging balls 7 may be fixedly attached to the eccentric joints 6-1, 6-2 so as not to rotate. With the above structure, when the rotating shafts 4-1, 4-2 of the helical gears 3-1, 3-2 rotate, the rotation is changed into eccentric movement by the eccentric joints 6-1, 6-2, and the rice ball 7 The tip performs a circular motion with a predetermined radius. The mutual circular movement of the fir balls 7 applies pressing force and vibration to the user's neck, etc., thereby causing pine surge. Moreover, 9 is a seat cover that covers the upper part of the rice ball 7.

The configuration of the pine surge device of this embodiment is as described above, and next, the structure of the fir ball 7 used in the pine surge device will be explained using FIG. 2.

The rice balls 7 are made by covering the surface of an elastic member 10 made of rubber, synthetic resin, etc., which has a cylindrical shape with a spherical tip, and has a smooth skin 11 made of an elastic material in the form of a thin film. In addition, eccentric joint 6
-1, 6-2, the shaft 8 is directly press-fitted into the elastic member 10 as shown in the figure. In order to reduce the contact area with the seat cover 9, a plurality of recesses 12 of a predetermined size and depth are provided on the surface of the spherical portion at the tip of the elastic member 10, as shown in the figure. The size, depth, and number of the recesses 12 are arbitrary. In this embodiment, by providing 36 recesses 12 of a predetermined size, the contact area of the spherical portion with the seat cover 9 is approximately half that of the case where there are no recesses 12. When these fir balls 7 are used in a pine surger, the area of contact with the seat cover 9 is reduced, so when the fir balls 7 move in a circular motion, the fir balls 7
The friction between the seat cover 9 and the seat cover 9 is reduced. Therefore, abnormal noise and vibration caused by friction are reduced, and the fir balls 7 move smoothly in a circular motion, resulting in a comfortable pine surge.

Further, if the surface of the elastic member 10 is coated with a smooth skin 11 as in the embodiment, the frictional resistance of the surface becomes smaller, and abnormal noise and vibration can be further effectively reduced.

Effects As described above, according to the present invention, friction is reduced by reducing the contact area between the rice balls and the seat cover, so abnormal noise and vibrations generated during the circular movement of the rice balls are extremely reduced, resulting in a comfortable seat cover. Pine surge is possible.
