In addition, in order to further improve the therapeutic effect,
There has been provided a stationary massage machine which can perform a plurality of massage techniques such as a shaking method of shaking while pressing a treatment site.

[Problems to be Solved by the Invention] However, in the case where a plurality of massage techniques can be performed together, the structure becomes complicated and large, and is limited to a stationary type equipped with a chair and the like, and the treatment site is shoulder, back,
There is a problem that it cannot be used for parts other than the limited parts such as the waist and legs.

On the other hand, a hand-held small tapping massage machine does not specify the treatment site compared to a stationary type and has general versatility that can be used for any part, but since it is small, a single tapping massager Although it can only be used for techniques, it is effective in recovering muscle fatigue such as shoulders, hips, and legs, but non-muscular parts such as the head, neck, and face are recoiled by the tapping action, and the aircraft is inevitable. There was a problem in that it was difficult to use because of pain in the part.

Therefore, an object of the present invention is to solve the above-mentioned problem, and perform a massage by a tapping method and a massage by a tremor method, so that the massager as a whole can be used effectively for both muscles and non-muscles. An object of the present invention is to provide a massage machine that can be reduced in size and that can be made compact and hand-held and used at any treatment site.

[Means for Solving the Problems] In order to achieve the object, the present invention has the following configuration as means for solving the problems. That is, in a massage machine in which a vibrator that can freely reciprocate is hit by a rotating member rotated by a motor, a vibrating plate rotatably engaged with an eccentric shaft provided on the rotating member, and the vibrating plate is swung. This is a configuration of a massage machine, comprising: an elastic support that freely supports the vibration plate; and the oscillating motion of the diaphragm by the rotating member via the eccentric shaft.

Further, a slide crush 24 that can slide with a certain pressing force on the surface of a plate body 25 provided on the gear box 4 is attached to a side of the lever 20 opposite to the eccentric pin 16. It is configured to facilitate the reciprocating movement.

Reference numeral 40 denotes an eccentric shaft, which is provided with a flange 44 having a larger diameter than the body 42 at one end of a main body 42 formed in a cylindrical shape.
A male screw 46 is formed on the side of the main body 42 opposite to the main body 42 at a position eccentric by a predetermined amount with respect to the axial center of the main body 42. The eccentric shaft 40 is attached to the rotating member 8 by screwing and fixing the male screw 46 to the rotating shaft 12 in a state where the center of the main body 42 is eccentric with the center of the rotating shaft 12. ing. Note that a male screw may be provided on the rotating shaft portion 12 and a female screw engaged with the male screw may be provided on the eccentric shaft 40. On the other hand, in the main body 42,
A vibration plate 48 formed in a rectangular shape is rotatably engaged with a mounting member 50 provided near the center thereof through an eccentric bearing 52. The vibrating plate 48 is made of synthetic resin or the like, and has a contact surface 56 provided with a substantially hemispherical projection 54 on one surface on the opposite side of the eccentric bearing 52.

The elastic strut 58 for supporting the diaphragm 48 is formed in a cylindrical shape using rubber or the like as a material, and one end thereof is connected to the case body 1.
It is fixed to the diaphragm 48 with the other end facing outside from the opening 60 provided on the side surface of the case body 1. In the present embodiment, a rectangular diaphragm
A total of four elastic struts 58 are provided, one near each corner of the rotary shaft 48, depending on the amount of eccentricity of the main body 42 with respect to the axial center of the rotary shaft 12 and the direction of the axial center of the rotary shaft 12 Is tilted by a predetermined amount to support the vibration plate 48 so as to be swingable in the plane of the outer surface of the case body 1.

Next, the operation of the massage machine of the present embodiment will be described.

When the motor 2 rotates the rotating member 8 via the worm 6, the rotating member 8 causes the eccentric pin 16 to swing and rotate as a circular motion about the central axis of the rotating shaft portion 12, and the lever 20 to rotate the oscillator shaft. Reciprocate in the axial direction of 26a, 26b. Then, the vibrator shafts 26a and 26b are reciprocated in the axial direction thereof to make the vibrators 28a and 28b
Is made to strike.

The rotating member 8 not only drives the eccentric pin 16 but also
The main body 42 of the eccentric shaft 40 is caused to perform a swing rotation in which the center of the eccentric shaft 40 is a circular motion about the center of the rotation shaft 12. The vibration plate 48 is driven by the swing rotation of the main body 42, and the eccentric bearing 52 causes a slip between the main body 42 and the vibration plate 48. As shown by arrow A in FIG. 2, the diaphragm 48 is supported by an elastic support so as to be able to make a circular motion having the same radius of rotation as the swing rotation of the main body 42. Swing as in A, and perform tremor movement.

Then, massage is performed by applying the vibrators 28a and 28b that make a tapping motion or the vibrating plate 48 that makes a trembling motion to an arbitrary part of the body. For example, the muscles such as the shoulders, hips, and legs can be massaged deep into the muscles by the tapping motion of the vibrators 28a and 28b to permeate the massage action. The non-muscular part, such as the head, neck, face, etc., which is unsuitable for use due to the beating of the tapping method or the improper use of the vibrators 28a, 28b by the tapping method, is mainly affected by the trembling motion of the diaphragm 48. An effective massage by the tremor method can be performed near the treatment site surface. At this time,
The small protrusion 34 provided on the vibrator 28a and the protrusion 5 provided on the diaphragm 48

In this method, concave cross-sectional rails are arranged above and below the gear box 4, and upper and lower edges of the lever 20 are fitted to the concave rails so that the lever 20 can slide freely, so that the lever 20 smoothly reciprocates. Things. When using this concave rail,
The bearing metals 30a and 30b may not be provided.

Further, in this embodiment, the eccentric shaft 40 is provided on the side opposite to the side on which the eccentric pins 16 of the rotating member 8 are provided, but it is also possible to provide the same on the same side. For example, a side surface of the case body 1 opposite to the opening 60 is opened, and the diaphragm 48 is swingably supported on an outer surface of the case body 1 opposite to the opening 60 of the case body 1 via an elastic strut 58. An eccentric bearing mounted on the diaphragm 48 by opening the approximate center of the plate 25 and extending the eccentric pin 16
If freely fitted to 52, diaphragm 48 will make the same trembling motion as in this embodiment.

As described above, the present invention is not limited to such embodiments at all, and can be implemented in various modes without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, in the massage machine of the present invention, the rotating member rotated by the motor causes the vibrator to strike, and at the same time, swings by the elastic strut via the eccentric shaft provided on the rotating member. Since the oscillating plate that is movably supported is oscillated, it is possible to perform both the massage by the tapping method and the massage by the tremor method, while reducing the size of the entire massage machine, It can be hand held and used at any treatment site.
For this reason, the muscles such as shoulders, hips and legs are hit with
For non-muscular parts such as neck and face, such as tremor method,
A more appropriate massage technique can be used depending on each part. Furthermore, even in the muscles,
It is not appropriate to perform a massage by suddenly striking the pain because the sudden reaction causes pain in the affected area,
Initially, after adjusting the physical condition by promoting the blood flow of the affected area with a mild massage by the tremor method, perform a beating method, or perform a gentle massage by the tremor method after a strong massage by the beating method. By doing so, a more effective massage effect can be provided, such as gradually adjusting the blood pressure or the like that has rapidly increased.
