Description

[Detailed Description of the Invention] The present invention is useful for promoting hypnosis, stiff shoulders, muscle pain, etc.
The present invention relates to vibrating bodies such as massaging devices used to treat low back pain, arthritis, rheumatism, sensitivity to cold, etc.

Conventionally, as a vibration generating device for this type of massaging device, a device is known in which an eccentric weight is provided on the rotating shaft of a motor to intermittently strike a diaphragm to vibrate, but the disadvantage is that the entire device becomes large. In addition, this vibration generating device has the disadvantage that the sound of impact between the diaphragm and the eccentric weight is always generated, which limits the scope of use of this vibration generator and makes it impractical.

There are also known devices that generate vibrations by applying pulsating current to a vibrating body consisting of an electromagnet and an elastic plate, but conventionally known vibrating bodies of this type generally have poor power efficiency and are difficult to generate the desired vibrations. had the disadvantage of requiring a large amount of power.

The present invention eliminates the drawbacks of these conventional vibration generators, does not generate any particular vibration noise, and can be used for blankets, futons, etc.
The purpose of the present invention is to provide a power-efficient vibrating body that can be freely installed on bedding such as pine tresses, clothes such as chiyotsuki and tanzen, cushions, mats, carpets, carpets, furniture such as sofas and chairs, etc.

That is, in the present invention, an elastic plate and a high magnetic permeability plate are fixedly arranged facing each other with an appropriate interval, and magnetic lines of force are generated inside the elastic plate, so that the weight ratio with the high magnetic permeability plate is approximately A wire ring with a magnetic core of 1/3 to about 3 times is formed into a flat shape, an attached elastic plate is used as a vibrating body, and by passing a pulsating current through the wire ring, approximately
The gist of this invention is a structure of a pulsating electromagnetic force vibrating body, which is characterized in that it vibrates by attracting and restoring the vibrating body by magnetomotive force generated at a cycle of 30 to 200 times.

Next, the present invention will be described with reference to illustrated embodiments.
Reference numeral 1 denotes an elastic plate made of rubber, synthetic resin, metal, etc., to which a wire ring 3 containing a magnetic core 2 is attached. Reference numeral 4 denotes a high magnetic permeability plate, which is constituted by a ferromagnetic metal plate such as an iron plate or a nickel plate, or by attaching these ferromagnetic metal plates to an elastic plate. Both sides of this high magnetic permeability plate 4 are bent to form a U-shaped frame, and the edges thereof are bent inward or outward to provide mounting flanges 5,5. The elastic plates 1 are supported oppositely by the mounting flanges 5, 5, and are attached using screws, rivets, or the like. When attaching the elastic plate 1, the wire ring 3 containing the magnetic core 2 is positioned inside, and an appropriate gap is provided between it and the high permeability plate 4. Reference numeral 6 denotes a handle, which is formed by extending a part of the high magnetic permeability plate 4, and is used to freely attach it to a flexible support 7 such as a mat.

To explain the operation of the vibrating body configured in this way, when a current is applied to the wire ring 3, a magnetomotive force is generated in the wire ring 3, and the high magnetic permeability plate 4 moves the magnetic core 2 of the wire ring 3.
On the other hand, when the current is interrupted and the magnetomotive force of the coil 3 disappears, the high magnetic permeability plate 4 returns to its original state. Therefore, if a pulsating flow is applied to the coil 3, a magnetomotive force is generated at a constant period, and the vibrating body consisting of the high magnetic permeability plate 4, the coil 3 with magnetic core 2, and the elastic plate 1 generates magnetomotive force at a constant period. Vibration is generated by repeating suction and restoration.

The vibrations generated by the vibrating body of the present invention are usually
It is taken out from the high magnetic permeability plate 4 side, but in that case, the weight ratio of the high magnetic permeability plate 4 and the coil 3 with two magnetic cores is set in the range of about 1/3 to 3 times in order to transmit vibration energy. That is, it is advantageous in terms of power efficiency.

In the present invention, it is sufficient that the elastic plate and the high magnetic permeability plate face each other and are fixedly arranged at an appropriate interval.
The elastic plate 1 may be fixed and attached to the elastic plate 1, or, for example, a wire ring with a magnetic core may be attached to the inside of one side of an elastic highly permeable metal plate bent in a U-shape or a U-shape. It is also possible to have a structure in which the plate and the high magnetic permeability plate are integrally formed of the same material. This structure has the advantage of being durable for long-term use, with less metal fatigue in the elastic plates. At that time, an elastic plate member of an appropriate shape and size, such as dieralumin, aluminum, or plastic, can be fixed to the outside of the other side of the bent highly permeable metal plate. The weight ratio of the side of the metal plate that functions as a high magnetic permeability plate and the side that functions as an elastic plate can be set within the above range.

Additionally, an E-shaped core can be used as the magnetic core, but if a columnar core like the one in this example is used, the vibrating body V can be thinned even when a large number of conductive wires are wound around the magnetic core 2 to form the wire ring 3. can be formed.

The vibrating body of the present invention is used by being embedded in a flexible support 7 such as sponge or rubber having an appropriate width, and usually two or more vibrating bodies V ₁ to V ₁₀ are shown in FIG. It is attached to a flexible support 7 such as a mat.

FIGS. 4 and 5 illustrate a method of feeding power to a vibrating body according to the present invention. In Figure 4, the AC power source AC is the time switch T and the thyristor SCR.
are connected to vibrating bodies V ₁ to V ₈ via. The thyristor SCR is electrically controlled by, for example, a phase control circuit G, and can supply a pulsating current of arbitrary magnitude to the vibrating bodies V ₁ to V ₈ for a preset time.

In the example of FIG. 5, the sine wave current from the alternating current power source AC is half-wave rectified by the diode D and then supplied to the vibrating bodies _V1 to _V10 .

The vibrating body of the present invention is not bulky as a whole because it uses a wire ring with a magnetic core as a source of magnetic lines of force, and can generate strong vibrations even with a small amount of electric power.
It can be freely installed on clothing such as tanzen, cushions, mats, carpets, carpets, sofas, bedding such as chairs, etc., and can apply vibration locally or globally to the human body. , can also provide moderate magnetic lines of force, stretch and relax muscles, improve blood circulation, promote hypnosis,
It is also highly effective in treating stiff shoulders, muscle pain, lower back pain, arthritis, rheumatism, sensitivity to cold, etc.

The present inventors believe that when this type of vibrating body is used for the above-mentioned purposes, the frequency of vibration is approximately 30 to 200 per second.
times per second, particularly about 50 to 120 times per second, has already been found to be preferred. The vibrating body of the present invention can easily supply vibrations of 50 or 100 times per second in the Kanto region and 60 or 120 times per second in the Kansai region by rectifying commercial alternating current as it is or by rectifying one wave or both waves. Therefore, there is no need to use a complicated oscillation device, and the weight of the entire device can be reduced, while significantly reducing energy consumption and cost.
