In order to further improve the therapeutic effect, for example,
There is known a stationary massage machine that can perform a plurality of massage techniques in combination, such as one that performs a kneading method and a tremor method as disclosed in Japanese Patent Publication No. 9021.

[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, the type is limited to a stationary type, and the treatment site is shoulder, back, waist, legs, etc. There was a problem that it could not be used for anything other than a specific part.

On the other hand, small hand-held massage machines do not specify the treatment site compared to stationary ones, and are versatile to be used at any site. I can only use one massage technique,
Even if it is effective for recovery from fatigue of the waist, legs, etc., it is difficult to use the head, neck, face, etc. due to the recoil due to the tapping action, causing the aircraft to dislodge or causing pain to the parts However, there is a problem that it is difficult to perform an effective massage on all the treatment sites only by the tapping method.

Therefore, an object of the present invention is to solve the above-mentioned problems, and it is possible to reduce the size of the entire massage machine while being able to combine the massage by the tapping method and the massage by the kneading method, and to provide a small hand-held type. Another object of the present invention is to provide a massage machine that can be used effectively for 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 arranged in a case, which makes a reciprocating oscillator vibrate by a rotating member that is rotatable in a case, the rotating member is formed by projecting an inclined axis inclined from a rotation center of the rotating member to the outside of the case. Provided integrally with
The tilting shaft and a kneading member that can play freely with each other are crowned with the tilting shaft, the tip of the kneading member is circularly moved by the rotating member through the tilting shaft, and the kneading member is kneaded. That is the configuration of the massage machine.

In addition, in order to allow the kneading member to freely occupy the tilting shaft, a rollable ball is interposed between the tip of the tilting shaft and the kneading member, and the rotation of the tilting shaft is performed. It is preferable to provide an inclined shaft bearing between the massaging member and the inclined shaft on the member side.

[Operation] In the massage machine of the present invention having the above-described configuration, the rotating rotating member causes the reciprocally movable vibrator to tap against the treatment site of the body and rotates the tilt axis about the rotation center of the rotating member. Then, the tip of the rubbing member rotatably crowned with the tilt axis is circularly moved, and the rubbing member is rubbed with respect to the treatment site of the body.

Also, at the time of the kneading motion, the ball interposed between the tip of the inclined shaft and the kneading member rolls, and the inclined bearing provided between the kneading member and the inclined shaft on the rotating member side of the inclined shaft is kneaded. The member and the tilt shaft are rotatably supported, and smooth rotation is performed between the kneading member and the tilt shaft.

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

When the motor 2 rotates the rotary member 8 via the worm 6, the rotary member 8 moves the eccentric pin 16 around the axis of the rotary shaft portion 12, and slides the bush 18 in the long side direction of the engagement port 20. At the same time, the lever 24 reciprocates the oscillator shafts 26a and 26b in the axial direction. Then, the oscillator shafts 26a and 26b are reciprocated in the axial direction, and the oscillators 30a and 30b are hit and moved.

The rotating member 8 not only drives the eccentric pin 16 but also
The tilt shaft 44 is rotated around the axis of the rotary shaft portion 12 via the vertical shaft 42, and the kneading balls 56 are rotated so that the tip of the kneading portion 64 makes a circular motion as shown by the arrow A in FIG. Let it.
When the rotating massage ball 56 is brought into contact with the body, the ball
54 rolls, the inclined shaft bearing 60 rotatably supports the kneading ball 56 and the inclined shaft 44, and smooth idling is performed between the kneading ball 56 and the inclined shaft 44, and the kneading ball 56 is Exercise against the body.

The massage is performed by applying the vibrators 30a and 30b performing such a tapping motion or the massaging ball 56 performing the massaging motion to an arbitrary treatment site of the body. Therefore, it is possible to perform both the massage by the tapping method and the massage by the kneading method while being a compact hand-held massage machine. For example, for the shoulders, hips, legs, etc., the massage action by the tapping method can be made to penetrate deep into the muscle mainly by the tapping motion of the vibrators 30a, 30b. In addition, for the head, neck, face, etc., which are unsuitable for use due to the impact of the tapping or the vibrators 30a, 30b, the kneading movement of the kneading balls 56 is mainly used for the treatment area. An effective massage by a kneading method can be performed near the surface. Of course, the massage by the kneading method may be performed on the shoulder, the waist, the leg, and the like. At this time, idle rotation is performed between the kneading ball 56 and the inclined shaft 44, so that inflammation of the treatment site due to friction during the kneading motion can be prevented.

Furthermore, even if it is a shoulder, a waist, a leg, etc., it is not appropriate to perform a massage by suddenly hitting the patient with a sudden reaction, causing pain in the treatment site due to a sudden reaction. After adjusting the physical condition by promoting the blood flow of the treatment site by massage, etc., the tapping method was performed, or the massage was strong after the tapping method, followed by a mild massage by the kneading method. A more effective massage effect such as gradually adjusting the blood pressure can be given by one machine.

Further, if the massage part 56 is pressed against the treatment site of the massage ball 56, an action of acupressure is also obtained, and the massage action and the acupressure action can be simultaneously obtained. At this time, massage balls 56 pressed against the treatment site
, The frictional force is generated between the ball and the inclined shaft 44, but the ball 54 rolls, and the inclined bearing 60
Since the 56 and the tilt shaft 44 are rotatably supported, a suitable massage effect can be obtained without causing inflammation at the treatment site due to friction.

Next, another embodiment will be described. In the embodiment of the massage machine shown in FIG. 3 and FIG. 4, a substantially disc-shaped attachment 100 is fitted to the kneading ball 56 of the above-mentioned embodiment so as to be fitted outside, and the attachment 100 is configured as a kneading member. . The attachment 100 includes a curved rubbing surface 102 that abuts on a treatment site of the body when the attachment 100 exercises.In this embodiment, a large number of substantially conical protrusions 104 are provided on the rubbing surface 102. . Also, this massage surface 1
On the opposite side of 02, a concave portion 106 that fits into the massaging ball 56 is provided, and by attaching the concave portion 106 to the tip of the massaging ball 56, the attachment 100 can be fixed to the massaging ball 56. .

The kneading ball 56 has a small portion in contact with the body, and is effective when it is desired to obtain a feeling of kneading a point such as an acupuncture point with a T-degree finger. Then, when rubbing a relatively wide treatment site as a whole, by attaching the attachment 100, it is possible to obtain a feeling of rubbing with just the palm.

In this way, if necessary, rub the attachment 100
By using it attached to 6, it is possible to perform massage massage according to the treatment site. Note that the attachment 100 may be formed integrally with the kneading balls 56.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, instead of using the inclined shaft 44, one end of a crankshaft having two eccentric parallel shafts is attached to the rotating shaft portion 12 and the other end is fitted to the kneading ball 56, thereby attaching the crankshaft to the rotating shaft portion 12. The present invention can also be implemented by forming an abstract inclined axis connecting one end of the crankshaft and the other end, and causing the tip of the massaging ball 56 to make a circular motion.

[Effects of the Invention] As described in detail above, the massage machine according to the present invention is configured such that the rotating rotating member makes the vibrator beat and the tilting axis is rotated, and the kneading member is made to knead. While it is possible to carry out massage together with the massage method, the size of the whole massage machine can be made compact, and it can be handheld and used at any treatment site. So, for example,
A more appropriate massage technique can be used depending on each part, such as a tapping method for the waist and legs, and a kneading method for the head, neck, face and the like. Of course, shoulders,
The rubbing method may be applied to the waist, legs, and the like. further,
After adjusting the physical condition of the shoulders, hips, legs, etc. by a light massage using a massage method, a tapping method is performed. A more effective massage effect can be given with one machine, such as gradually adjusting the condition, etc., and the usability becomes very good. Furthermore, if the massaging member is pressed against the treatment site, a massage effect by the acupressure method in addition to the massaging method can be obtained at the same time.

In addition, since the ball and the inclined shaft bearing allow smooth rotation between the kneading member and the inclined shaft, even if the kneading member is pressed against the treatment site, inflammation does not occur due to friction, and the kneading action is performed. In addition to the above, a stronger acupressure action can be performed.
