Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a pine surge device in various pine surge machines such as a chair-type pine serge machine or a bed-type pine surge machine.

There are a wide variety of kneading tools used in pine surge machines, but pine surge devices equipped with a pair of left and right inclined kneading wheels, preferably eccentric slanted kneading wheels, have recently been widely adopted because they produce excellent pine surge effects. .

However, as mentioned above, in the pine surge device in which the inclined massaging wheels are attached to the rotating shaft at intervals, it is possible to impart a pine surge effect that combines the lateral direction and the pushing direction to the muscles of the body by rotating the rotating shaft. However, these pine surge effects are simple and are repeated in the same cycle every rotation of the rotary drive shaft, and are still not satisfactory.

Furthermore, the width of the lateral rubbing is determined by the angle of inclination of the slanted rolling wheels, and if the angle of inclination of the slanted rolling wheels is set large in order to increase the width of lateral rubbing, the load on the rotating shaft will increase. The left and right inclined rubbing wheels approach each other abnormally with each rotation, making it difficult to achieve a comfortable pine surge effect.

In the present invention, it is possible to increase the strength by increasing the lateral rubbing width without increasing the inclination angle of the inclined rubbing ring and by changing the movement of the rubbing ring. To provide a pine surge device that can set a constant fluctuation cycle in pine surge motion by a massaging ring with a period of one rotation or more.

The drawings showing the embodiments of the present invention will be explained below.
1 is a rotary drive shaft, and 2, 2 are a pair of left and right massagers, which are supported by a frame 3 at both ends of the drive shaft 1, and are connected, for example, by a motor 4 to a pulley 5. Warm 6
, a worm wheel 7 or other transmission means.

Moreover, the massaging tools 2, 2 are attached to the drive shaft 1 at intervals, and include a boss body 8 that rotates together with the drive shaft 1, and a boss body 8r.
/C It consists of a rubbing ring 10 which is rotatably added through a bearing 9, and a rubbing ring 10 is added through the bearing 9.
is fitted and supported by the outer circumferential surface 11 of the boss body 8, which is formed to be inclined and eccentric with respect to the axis of the drive shaft 1, so that the left and right massaging tools 2, 2 are inclined in opposite directions.

As the boss body 80 rotates, its acting portion 12.degree. 12 reciprocates in the lateral direction while changing its position in the front-rear direction to apply a pine surge effect.

The present invention provides a pine surge device equipped with the above-mentioned inclined massaging tools 2, 2, in which the above-described boss body 8 is connected to the rotary drive shaft 1.
The massaging tools 2, 2 are rotatable together with the drive shaft 1 and slidable in the axial direction of the drive shaft 1, and the massaging tools 2, 2 are elastically biased in opposite directions by a coil spring 13 mounted around the drive shaft 1. At the same time, the massaging tools 2, 2 are moved laterally in the axial direction of the drive shaft 1 as the massaging tools 2 rotate, on the opposite side to the contact surface of the coil spring 13 with respect to the massaging tools 2, 2. A rotary cam 14 is provided for the purpose of massaging, and in addition to the massaging action due to the inclination and eccentricity of the massaging tools 2, 2, the massaging action due to the lateral movement of the massaging tool 2 part 2 itself and the movement of the massaging ring are changed. It is designed so that the strength and weakness can be adjusted by adjusting the angle.

In the figure, reference numeral 15 denotes a guide groove for lateral movement of the boss body 8, and the boss body 8 and the rotary drive shaft 1 are used to guide a part of the inner diameter part of the boss body 8 as shown in FIG. The boss body 8 is fitted into the groove 15 so that the boss body 8 can rotate together with the drive shaft 1 and move laterally along the drive shaft 1.

Reference numeral 16 denotes a friction-reducing member disposed on the abutting surface of the boss body 8 with the rotary cam 14, and the friction-reducing member 16 is made of, for example, synthetic resin with excellent sliding properties.

In the embodiment shown in FIG.
, 2 are elastically biased outward as shown by arrows, and gears 17, 17 are applied from the drive shaft 1 to the outer surface of the massaging tools 2, 2.
This shows a mode in which the cam surface 18 of the rotary cam 14 driven via the cam surface 18 is brought into contact with the rotary cam 14 .

The shape of the cam surface 18 of the rotary cam 14 is preferably inclined with respect to a plane perpendicular to the rotational axis of the rotary cam 14, and further, as shown in FIG. It is also possible to use a ring with a desired smooth undulation to give different changes to the movement of the rubbing wheel.

The rotating cam 14 is preferably driven at a rotation speed slower than that of the drive shaft 1, for example, 1/2 to 1/3 of the rotation speed of the drive shaft 1.

FIG. 5 shows the massaging tools 2, 2 in the embodiment shown in FIG.
The rotation ratio between the rotating cam 14 and the rotating cam 14 is set to 2:1, and the maximum protrusion 14' of the rotating cam 14 is set to the outside of the massaging tool 2 when the working surfaces 12.12 of the massaging tools 2, 2 are most separated from each other. This figure schematically shows the operation procedure when the device is set in contact with the friction reducing member 16 on the side surface.
The operation of the device of the present invention will be described based on the drawings. In A of FIG. 5, the coil spring 13 is most compressed and the distance B between the boss bodies 8 is the minimum.

When the device is driven and the rotary drive shaft 1 is rotated by 1/2 and the rotary cam 14 is rotated by 1/4, the working surfaces 12, 12 of the massaging tool 2°2 move to the inner surface and the distance between them is reduced. The massaging tool 2 part 2 itself is laterally moved outward by the elasticity of the coil spring 13.

(Fig. 5) Then, when the drive shaft 1 is further rotated by 1/2 and the rotary cam 14 is rotated by 1/4, the working surfaces 12, 12 of the massaging tools 2, 2 move outward. , the massaging tool 2 part 2 itself is laterally moved further outward, and its working surfaces 12, 1
The interval a2 of 2 is larger than the interval a□ of A in FIG.

(C in Fig. 5) Then, when the drive shaft 1 advances 1/2 rotation and the rotary cam 14 advances 1/4 rotation, the massaging tool 2,
The working surface 12.12 of the massaging device 2 moves inward, and the massaging tool 2 part 2 itself is laterally moved inward by the rotating cam 14 to be in the same position as the opening in FIG. 5 above (FIG. 5, 2). The rotation continues, and when the drive shaft 1 has rotated twice from the state shown in FIG. 5A, one cycle ends and the drive shaft 1 returns to the state shown in FIG. 5A.

Note that the above-mentioned action in FIG. 5 shows only the expansion and contraction of the working surfaces 12.12 of the massaging tools 2, 2, and the lateral movement of the massaging tools 2.2 itself by the rotating cam 14.
During this time, as mentioned above, since the rubbing ring 10.10 is inclined and eccentrically attached to the boss body 8,
The kneading surface 12.12 rotates and moves while periodically changing its position by a compound movement in the lateral direction and the front-back direction, thereby performing a pine surge effect.

FIG. 4 also shows that the coil springs 13 are provided on the outsides of the left and right massaging tools 2.2 to elastically urge the massaging tools 2.2 inwardly, and the inner surface of the massaging tools 2.2 is 2 shows an embodiment in which a rotary cam 14 is provided with cam surfaces 18° 18 of the same shape on both sides and is driven from a rotary drive shaft 1 via a gear train 19, and is similar to the previous embodiment. It has the following effects.

As described in detail above, the pine surge device according to the present invention comprises a left and right massager consisting of a boss body 8 that rotates together with the rotary drive shaft 1, and an inclined rubbing ring 10 that is rotatably attached to the boss body 8 via a bearing 9. A pair of massaging tools 2, 2 are mounted slidably in the axial direction of the rotary drive shaft 1, and the pair of massaging tools 2
. Since the massaging tools 2, 2 are moved laterally in the axial direction of the rotary drive shaft 1 by the action of the rotary cam 14, the massaging tools 2, 2 can be used in a pine massage device equipped with a pair of left and right inclined massaging tools. In addition to the massaging action caused by the tilted eccentricity of the massaging ring, it is possible to perform an active lateral push pine surge effect by the lateral movement of the massaging tools themselves using a rotating cam, and a circular pine surge effect with varying degrees of strength. Compared to the pine surge device of 2005, this device can provide a more effective massaging action that gives a feeling similar to manual pine surge.
