Description

[Detailed description of the invention] Technical field The present invention relates to improvements in massaging machines.

Conventional techniques In general, massage techniques include a technique in which the skin is rubbed lightly (light rubbing method), a technique in which massaging and rubbing are performed together by adding massaging to this light rubbing method (strong rubbing method), and a technique in which the muscles are massaged (massaging method). 〓 method), a technique that adds kneading to this kneading method and performs the kneading together (an ㉓ method), a technique of pounding (beating method), a technique of pressing while vibrating (shaken method), an intermittent or Various techniques are used, such as applying pressure to one area continuously (compression method) and forcing each part of the body to move (exercise method). The reality is that there is no method that combines each technique to obtain the massaging effects of multiple techniques at the same time, and the fact is that compared to manual massage, it is not possible to obtain a massage effect that is even more subtle than manual massage.

Purpose of the Invention The present invention is an attempt to improve the conventional situation as described above. It is an object of the present invention to provide a massaging machine which can simultaneously obtain a vibration effect by a shaking method.

Structure of the Invention That is, the present invention provides a massaging action and acupressure action through the rocking rotation of the massaging balls, and a vibration action through the vibration of a diaphragm, particularly the vibration action obtained by the diaphragm.

Additionally, FIG. 5 shows an electric circuit diagram of the massaging machine, and FIG. 6 shows an overload prevention circuit incorporated in the electric circuit diagram.

Next, its effect will be explained. By turning on the power switch to drive the motor 2, the driving force is transmitted to the rotating shafts 7, 7 via the drive shaft 5, worm 6, and worm wheels 4, 4. And the driving force of the motor 2 is the rotating shaft 7, 7
The inclined shaft portions 7b, 7b
A state in which a pair of massaging balls 9, 9 oscillates and rotates in relative directions through the oscillating rotation of (revolution of massaging balls 9)
is obtained. In this way, by bringing the affected area into pressure contact with both the massaging balls 9, 9 while the massaging balls 9, 9 oscillate and rotate (revolution) in the relative directions, the contact surface between the affected area and the massaging balls 9, 9 The affected area is pulled in the direction of the rocking rotation of both the massaging balls 9, 9 through the frictional resistance generated between the massaging balls 9, 9, and both massaging balls 9, 9 are massaged in a state where the massaging balls 9, 9 are oscillated and rotated to a position where they face each other. An effect of grasping the affected area, ie, a massaging effect, can be obtained between the balls 9,9. Furthermore, as described above, by achieving a state in which both the massaging balls 9, 9 roll while being in pressure contact with the affected area, an effect of applying acupressure to the affected area can be obtained. That is, in addition to the kneading action, acupressure action can be obtained simultaneously. In other words, when the amount of displacement of the massaging balls 9, 9 is within the range of the amount of play obtained from the massaging balls 9, 9 (free rotation state), an acupressure effect can be obtained,
A kneading action can be obtained when the amount of displacement exceeds the amount of play.

On the other hand, by driving the vibration motor 17, the motor is vibrated via the vibration mechanism built into the motor, and the vibrations thus generated are transmitted to the diaphragm 16 via the flange 18 and the vibration member 19. communicated. That is, the vibration motor 1
The rotation of 7 allows the diaphragm 16 to vibrate in a complex manner not only in the vertical direction but also in the longitudinal and horizontal directions.

In addition to the vibrations generated by the vibration motor 17 being transmitted to the diaphragm 16 in this way, the vibrations are transmitted through the housing 1 and the like to the massaging balls 9,
9. That is, a state is obtained in which both the massaging balls 9, 9 vibrate and rotate in an oscillating manner. As the massaging balls 9 vibrate and rotate in this manner, the massaging action, the finger pressure action, and the vibration action are combined to produce a complex massaging effect.

Note that the rotating shaft 7 is provided with a bearing 10 having a flange 10', and the kneading balls 9 are attached to the flange 10' by screws 11, so that attachment and detachment are easy and the bearing 10 has a flange 10'. A strong installation can be achieved without falling off due to dynamic rotation. Furthermore, since the massaging balls 9 are covered with the cover 22, it is possible to prevent the problem of the affected area being caught between the massaging balls 9. Furthermore, since an overload prevention mechanism is provided, if an overload occurs on the massaging balls 9, 9, in other words, if the affected area is caught between the massaging balls 9, this can be prevented. It can be avoided.

Effects of the Invention The present invention is constructed as described above, and includes:
As mentioned above, the kneading balls are rotatably mounted on the tip of the inclined shaft of the rotary shaft which has a vertical shaft part and an inclined shaft part and is bent into a dogleg shape, and the kneading balls are oscillated and rotated. While it is provided to obtain a kneading action and acupressure action, a diaphragm is supported via an elastic support on the same surface as the kneading balls, and the diaphragm is vibrated via a vibration motor to obtain a vibration action. By providing this, in addition to the massaging action and acupressure action of the massaging balls, it is possible to simultaneously obtain the vibration action of the diaphragm, thereby making it possible to effectively obtain the massaging effect.

In particular, in the present invention, the vibration action of the diaphragm is transmitted to the massaging balls, and the vibration action is complexly combined with the massaging action of the massaging balls and the acupressure action in the massaging balls, which can be applied to the affected area. I was able to increase my pleasure even more.

In addition, in the present invention, the diaphragm is supported by an elastic support, and the vibration generated by the vibration motor is transmitted to the diaphragm. Coupled with the interposition of the elastic supporting legs, it has become possible to obtain an effective vibration effect, that is, a complex vibration effect not only in the vertical direction but also in the front-rear and left-right directions. Furthermore, by covering the massaging balls with a cover, it has become possible to effectively prevent the problem of the affected area being caught between the massaging balls. That is,
Together with the provision of an overload prevention mechanism, we have been able to significantly improve its safety.
