Description

  The present invention relates to a health step for promoting health.

The sole of the foot is said to be the second heart. Stimulating the sole of the foot improves blood circulation, improves the function of the internal organs, raises basal metabolism, and has a dieting effect. A bioelectric current of 100 to 200 μA flows in the body, and when a series of electrical changes occur in the cell membrane due to weak current stimulation in nerve fibers and muscle fibers, the electrical changes generated in one place cause adjacent portions. Is stimulated one after another, and the excitement is transmitted through the fibers. And on the soles of the feet, there are reflex zones corresponding to each organ of the body, and as shown in FIG. 11, 30 reflexes that stimulate or massage each vase, as shown in FIG. Left hemisphere 2. Frontal sinus 3. Cerebellum / brain stem 4. Pituitary gland 5. Trigeminal nerve 6. Nose 7. Neck 7. Neck 7. Left eye 9. Left ear 11. Right trapezius muscle (right half and right neck) Shoulder) 12. Thyroid 13. Parathyroid 14. Right lung and bronchus 15. Stomach 16. Duodenum 17. Pancreas 18. Liver 19. Gallbladder 20. Abdominal nerve sores (digestive organ) 21. Right adrenal 22. Right kidney 23. Right ureter 24. Bladder 25. Small intestine 26. Cecum (appendices) 27. Ileicovalvular valve 28. Ascending colon 29. Transverse colon 36. Right gonad (ovary / testis) 53. By doing so, the function of each organ corresponding to the pot can be activated.
Methods for stimulating the sole of the foot include methods of applying pressure (such as finger pressure), methods of applying heat (such as warmth), and methods of applying electrical stimulation (magnetic, low-frequency current, weak current) It is most effective to flow a pulse-like weak current into the cell tissue. (Magnety uses a small electromotive force generated in a magnetic field. Low-frequency treatment milliampere currents flow almost subcutaneously.) And by letting a weak current (microcurrent) flow from the outside It has been found that the production of ATP (adenosine triphosphate), an energy necessary for cell activity, is promoted in the cell.
Therefore, as a health device for stimulating the sole of the foot, for example, Japanese Patent Application Laid-Open No. 7-250880 and registered utility model No. 3083681 have been proposed. However, any of the proposed configurations only gave a pressing stimulus to the sole of the foot, and the effect of giving the sole to the foot was small. In addition, when the feet were placed on the proposed health device and the whole weight was applied, the pressure applied from the stimulating projections was too great and accompanied by considerable pain.
(For example, in a person with a weight of 50 kg, the load on the heel part is around 2 kg per square centimeter, and if you step on it, it will add several times more load.) Therefore, if you step on the health device, it will be more painful and continue. It was difficult to implement.

JP-A-7-250880 registered utility model 3083681

  The present invention has been made in view of the above-mentioned problems, and by providing a foot with a foot placed on a foot platform, an electrical stimulation effect can be obtained, and even when the foot is placed on the foot platform, The object is to provide an unprecedented health stepping board that promotes health with less pain and a stimulating effect.

In order to solve the above-described problems, the present invention provides a structure in which a piezoelectric body that generates electricity by pressure is provided inside a platform on which a foot is placed, and the piezoelectric body is generated by deformation due to bending. A method of generating electricity with the pressure applied to the piezoelectric body using the piezoelectric effect, which is the principle of electromotive force, will be described with reference to FIG. 10. In FIG. 10 (a), the direction of the arrow (↓) on the surface of the piezoelectric body. When a compressive force (compressive stress) is applied, the piezoelectric body is distorted in the direction of contraction as shown in the figure, and an electromotive force i is generated at that time. Next, when the compressing force is removed, the piezoelectric body returns to its original shape, and an electromotive force i in the opposite direction is generated at that time. In FIG. 10B, when a bending force (shear stress) in the direction of the arrow (↓ & ↑) is applied to the surface of the piezoelectric body, the piezoelectric body is distorted in the bending direction as shown in FIG. Power up. Next, when the bending force is removed, the piezoelectric body returns to its original shape, and an electromotive force i in the opposite direction is generated at that time. In this case, since the displacement amount distorted by the bending force is much larger than the displacement amount distorted by the compressing force, the electromotive current generated by the bending force is much larger. Therefore, when the electromotive force is generated by the displacement due to bending, the electromotive force can be sufficiently generated even with a slight pressure.
Therefore, the present invention is configured to generate electricity by the bending force (shear stress) described above, and therefore uses the elastic and flexible properties of metals, plastics, and rubbers. A substrate is made of metal, plastic, or rubber that is appropriately bent and elastic, and a piezoelectric body is provided on the substrate in a flat and thin shape, so that even if a large pressure is applied to the substrate, the piezoelectric body is in the pressure direction. Can be bent and deformed together by the elastic force of the substrate, and when the pressure is removed, the piezoelectric body returns to its original shape by the elastic force of the substrate, so the pressure from any direction applied on the substrate But it can generate electricity. Since the piezoelectric body is provided in a flat and thin shape, the piezoelectric body is appropriately bent so that the piezoelectric body is not broken. By providing the substrate in the platform, if you step on the platform, you can continue to generate electricity, and the weak skin that is generated by the piezoelectric body contacts the skin tissue on the sole of the foot that contacts the conductive part. It is configured to energize the inside.

  In addition, by forming the piezoelectric body itself with a suitably flexible piezoelectric film body, even if a separate substrate is not provided, the piezoelectric film body deforms in that direction when pressure is applied to the piezoelectric film body. However, since the piezoelectric film body returns to its original shape due to the elasticity of the piezoelectric film body and the elasticity of the underlay in the platform, it can be similarly generated, and the piezoelectric film body is installed in the platform and the foot is placed on the platform When the foot is stepped on, the electromotive force can be continuously generated in the same manner, and a weak current generated by the piezoelectric film body is applied to the skin tissue on the sole of the foot contacting the conductive portion.

  The health step of the present invention can apply a weak current stimulus generated by a non-power source to the sole of the foot, and as a configuration, the piezoelectric body is provided in a flat and thin shape on an elastic substrate that is appropriately bent. The piezoelectric body provided on the substrate can be electromotively deformed by following the bending deformation of the substrate, regardless of the pressure applied from any direction, and the displacement due to the bending deformation is the deformation of the compression. Therefore, it is possible to increase the electromotive current to be generated, efficiently generate the electric current, and pass the electromotive current into the skin tissue on the sole of the foot.

  In addition, by forming the piezoelectric body itself with a flexible and elastic piezoelectric film body, an electromotive force is generated by the deformation of the piezoelectric film body in the bending direction and the tensile direction, regardless of the pressure applied to the piezoelectric film body from any direction. Therefore, it is possible to increase the electromotive current that is generated even with a small applied pressure, and to efficiently apply the electromotive current that is generated in the skin tissue on the sole of the foot.

  In addition, since the piezoelectric body and the piezoelectric film body constituting the present invention can be configured to be very thin, the thickness of the step board can be configured to be thin, and the piezoelectric body provided on the substrate against the pressure and impact applied by the body load can be reduced. Since the piezoelectric body is appropriately bent in the direction of the force, the piezoelectric body can be implemented without cracking, and by appropriately bending in the direction of the applied force, the impact can be absorbed and the role of the cushion can be achieved. The health stool of the present invention can promote health by applying a weak current stimulation to the sole of the foot without causing pain.

The configuration of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows the appearance of the present invention, FIG. 1 (a) shows a front view thereof, and FIG. 1 (b) shows a perspective view thereof. 2 (a) and 3 (a) are longitudinal sectional views in the XY direction shown in FIG. 1 (b), and FIGS. 2 (b) and 3 (b) are exploded into respective components. FIG.

  FIG. 2 shows a configuration in which the healthy step 1 of the present invention is implemented by providing a flat thin piezoelectric body 4 on a substrate 3. The health step 1 is composed of an overlay portion 1a and an underlay portion 1c, and the underlay portion 1c is formed of a foamed urethane resin, a foamable synthetic rubber, or the like of an appropriately elastic porous synthetic resin material. As shown in FIG. 2B, a concave step groove portion 1f is formed in the underlay portion 1c, and a conductive portion 6: 6A in which a conductive rubber is formed horizontally is fitted into the step groove portion 1f, and the conductive portion 6: A plurality of convex portions 6a, 6a... 6a are formed and provided on the surface of 6A as shown in the figure. Next, on the surface of the substrate 3 made of 42 ALLOY alloy, as shown in FIGS. 8A and 8B, the piezoelectric body 4 is provided in a flat and thin shape, and the electrode 5 is provided on the upper surface of the piezoelectric body 4 so as to be integrated. Configure. The integrated substrate 3 is stacked on the flat surface of the flange portion of the conductive portion 6: 6A, and the insulating material 2 made of a ring-shaped resin material is stacked thereon. The insulating material 2 serves to insulate the conductive portion 6: 6B from the substrate 3 and the conductive portion 6: 6A. A conductive portion 6: 6B in which a conductive rubber is formed in a circular shape is superimposed on the insulating material 2, and the conductive portion 6: 6B and the electrode 5 are brought into contact with each other through the opening 2a to conduct. A plurality of convex portions 6b, 6b... 6b are formed on the surface of the conductive portion 6: 6B. In addition, openings 1b, 1b,... 1b are formed at the opposing positions of the protrusions 6a, 6a,... 6a and the protrusions 6b, 6b,. As shown in b), each convex part 6a and convex part 6b are fitted into the openings 1b, 1b... 1b to project, and the overlay part 1a and the underlying part 1c are combined to constitute the healthy step 1 It is a thing.

  Here, in the configuration shown in FIG. 2 (a), the principle of actually putting the foot on the healthy step 1 and energizing the sole of the foot will be described with reference to FIG. When a foot is placed on the healthy step 1 constructed as described above, a load due to the weight of the body is applied on the healthy step 1, and the protruding portions 6a, 6a... 6a and the protruding portions 6b, 6b projecting on the healthy step 1 ... Each tip of 6b contacts the skin surface of the sole of the foot. Here, the load on the healthy step 1 is the largest in the center of the heel portion. Since the underlay portion 1c has appropriate elasticity, if the foot is stepped in that state, the deformation shown in FIGS. 4 (b) to 4 (c) occurs every time the foot is stepped on, and the substrate 3 is subjected to pressure from above. Thus, a deformation that bends inwardly as shown in the figure occurs. Then, the piezoelectric body 4 provided in a flat thin shape on the surface of the substrate 3 follows the deformation of the bending of the substrate 3 and is similarly bent inward to bend. An electromotive current i flowing in one direction is generated. The electromotive force i is applied to the conductive portion 6: 6A in contact with the electrode 5 and the conductive portion 6: 6B in contact with the substrate 3, and is formed on the surfaces of the conductive portion 6: 6A and the conductive portion 6: 6B. .. 6a and 6b, 6b... 6b are energized into the skin tissue on the soles of the abutting feet. Further, every time the foot is stepped up and raised, the change shown in FIG. 4C to FIG. 4B occurs, and an electromotive current i in the opposite direction to the electromotive current i is generated. The electromotive force i is similarly energized into the skin tissue on the soles of the abutting feet. Therefore, the health platform 1 of the present invention can energize a weak electromotive force i into the skin tissue on the sole of the foot every time the footrest 1 is stepped on without a power source. The substrate 3 constituting the present invention and the piezoelectric body 4 provided in a flat and thin shape on the surface thereof are suitably elastic and can be configured in a very thin and thin shape, so that they are not bulky and are resistant to pressure and impact from above. Since it bends in proportion to the magnitude of its force, it can serve as a cushion that absorbs and softens the impact from above.

  Here, since the piezoelectric body 4 generates electricity even with a slight strain in the bending direction, it can be carried out even if the underlying portion 1c has a slight elasticity, and can be distorted. Even if there is no elasticity, the conductive portion 6: 6A made of conductive rubber has some elasticity, so that it is possible to generate electricity even with the elastic strain. In the configuration of the present embodiment, the insulating material 2 is stacked on the surface of the conductive portion 6: 6A, and the substrate 3, the piezoelectric body 4, and the electrode 5 are integrated on the surface. May be provided such that the electrode 5 and the conductive portion 6: 6A are in contact with each other, and the substrate 3 and the conductive portion 6: 6B are in contact with each other. Further, as shown in FIG. 9B, the LED 7 may be connected in parallel to the piezoelectric body 4, and since the LED 7 is a semiconductor, it is lit with an electromotive current in one direction, and the lighting causes the piezoelectric body 4 to be lit. The state of electricity can be confirmed visually. In FIG. 6, a display window 1g is provided on the surface of the healthy step 1 so that the LED 7 can be seen from the display window 1g. The convex portions 6a, 6a... 6a and the convex portions 6b, 6b... 6b formed on the surfaces of the conductive portions 6: 6A and the conductive portions 6: 6B are arranged at positions facing the crucibles. For example, a typical foot pot has a spring, and applying a stimulus to it has an effect on kidney disease, swelling, coldness, high blood pressure, insomnia and the like.

As shown in FIGS. 2 (a) and 2 (b), when the substrate 3 constituting the present invention is made of metal, it can be implemented with 42ALLOY made of brass, aluminum, copper, alloy having an appropriate thickness and elasticity, etc. The substrate 3 may be formed by depositing aluminum on the surface of a thin plastic material, or by forming a film of conductive carbon or the like. Further, the entire substrate 3 may be formed of a conductive rubber or a conductive plastic material. The thickness of the substrate 3 may be any thickness that is appropriately bent and has elasticity, and when formed by a metal plate, as an example, depending on the metal, the thickness is from 2 to 1 mm or less to 0.5 to 0.5. It is even better if it is 0.3 mm or less and 0.2 mm or less. As the piezoelectric (piezo) ceramic 4a, in addition to lead zirconate titanate (PZT), barium titanate (BaTiO ₃ ), lead titanate, lead niobate, lithium niobate and the like are sintered. The piezoelectric film 4b can be made of a film-like polyvinylidene fluoride (PVDF) or the like. By applying pressure to any substance, electric polarization occurs in the substance and an electromotive current is generated.

  In FIG. 3, the substrate 3 configured in the previous embodiment is not provided, and only the piezoelectric film 4b is used as the piezoelectric body 4 as shown in FIG. 8C. For example, a piezoelectric (piezo) film 4b made of polyvinylidene fluoride (PVDF) manufactured by MSI (Measurement Specialties. Inc.) in the United States is appropriately bent and elastic, and the substrate is the same as in the previous embodiment. Even if 3 is not provided, the piezoelectric (piezo) film 4b is bent and deformed by pressure to generate an electromotive current. When the pressure is removed and the original shape is restored, a reverse electromotive force is generated. The piezoelectric (piezo) film 4b generates an electromotive current even by a tensile force, and can generate an electromotive voltage 10 times or more that of the piezoelectric (piezo) ceramic 4a. Therefore, if the present invention is constituted by the piezoelectric (piezo) film 4b, only a small area is required, and the thickness is 28 μm, 52 μm, and 110 μm, which are very thin and not bulky. The electrode 5 can be configured by coating the piezoelectric material 4 with a metal material. Examples of the coating method include a sputtering method using a nickel copper alloy, a silver silk screen printing method, and an aluminum vapor deposition method. The electrode 5 provided on the surface of the piezoelectric film 4b may be provided only on the upper surface, but may be provided on both the upper and lower surfaces as shown in FIG. 8C in order to improve conductivity. The area of the electrode 5 provided on the surface of the piezoelectric film 4b may be provided over the entire surface, but may be provided with a slightly smaller area as shown in FIG. In this configuration, a slight gap is formed between the electrode 5 and the conductive portion 6A, so that it is easy to insulate. As shown in FIG. 3 (a), when the foot is put on the healthy step 1 as shown in FIG. 3 (a), as shown in FIG. 4 (d), the piezoelectric film 4b provided on the appropriately elastic underlay 1c is The pressure due to the load of the foot is bent following the deformation of the underlay 1c, and an electromotive current is generated as in the previous embodiment. And the piezoelectric film 4b is not cracked at all, and as shown in FIG. 4 (e), the piezoelectric film 4b is bent by the pressure from above, and at the same time, a force in the tensile direction is generated and stretches in the lateral direction. Electromotive force can also be generated by elongation strain. Therefore, in the configuration of the piezoelectric film 4b of the present invention shown in FIG. 3, an electromotive current can be generated and implemented with both bending and stretching strains.

  In order to make the piezoelectric film 4b moisture-proof, the entire piezoelectric film 4b is encapsulated with a resin material 9 as shown in FIG. 8D, and electrode terminals 5a and 5a are provided on the electrodes 5 on the upper and lower surfaces of the piezoelectric film 4b. The conductive portions 6A and the conductive portions 6B may be connected to the electrode terminals 5a and 5a, respectively, and the present invention may be implemented with the configuration. In this configuration, the elasticity of the resin material 9 is further added, and the resin material 9 is easily returned to the original state, and can efficiently generate electricity.

  FIG. 5 shows an embodiment in which the underlaying portion 1c constituting the present invention is made of a non-elastic base material. As an embodiment, the underlaying portion 1c may be implemented by the configuration shown in FIGS. 5 (a) and 5 (b). a) shows a case where a space portion 1d is formed at a portion on which the piezoelectric body 4 is placed in the step groove portion 1f formed in the underlay portion 1c. When a load is applied with the foot placed and the substrate 3 bends, there is a space where the substrate 3 bends in the space 1d. Therefore, an electromotive current can be similarly generated and implemented by the bending strain. FIG. 5B shows an elastic part 1e provided in the same part of the underlay part 1c. When a load is applied on the foot and the substrate 3 is bent, the elastic part 1e is appropriately dented by the pressure. An electromotive force can be generated and implemented by bending strain. 2 and 3, the underlaying portion 1c may be implemented with the configuration shown in FIGS. 5 (a) and 5 (b). Similarly, it can be implemented by generating an electromotive current. is there. Further, even if the underlay portion 1c is not elastic at all, the conductive portion 6: 6A made of conductive rubber is slightly elastic, so that the substrate 3 can be appropriately bent by the elasticity and can be similarly electromotive. The conductive portion 6 may have a conductivity and be appropriately elastic as long as the conductive portion 6 is composed of a conductive plastic or a plastic material obtained by vapor deposition of aluminum in addition to the conductive rubber. Further, the position where the piezoelectric body 4 is provided may be provided on the arch or toe side in addition to the hook portion shown in the embodiment.

  FIG. 6 shows a configuration in which the exercise effect of the stepping can be confirmed in addition to the stepping effect of the weak current generated by the stepping in the healthy step 1 of the present invention. Print a footprint picture on the surface of the healthy step 1 on which you place your foot, and place the foot on the footstep picture to accurately place the convex 6a and convex 6b against each vase on the sole of the foot. By configuring the circuit shown in FIG. 9B, the weak current that is generated every time the foot is stepped on can be confirmed by the light of the LED 7 that is lit from the display window 1f. It can be confirmed that the back of the foot is energized.

  9C, the light emitted from the LED 7 can be detected by the phototransistor of the sensor 10a, the light receiving surface thereof is provided facing the LED 7, and the number of steps taken by the detected optical signal is counted. 10b is counted, and the counted number is displayed on a liquid crystal display on the display unit 10c provided on the healthy step board 1. The counter 10b counts how many times the healthy step 1 has been stepped on in the configuration, and the cumulative number is counted by the number displayed on the display unit 10c. Further, with the configuration applied, the number of steps counted by the counter 10b can be converted into data, and the data can be taken into the personal computer from the connector 11 via the USB memory as shown in FIG. As shown in FIG. 12 (a), the indoor stepping exercise is set as a daily routine, the daily stepping number is stored in the counter 10b, and the accumulated data is connected to the connector 11 by connecting the USB memory to the data. As shown in FIG. 12B, the data stored in the USB memory can be stored in the personal computer and daily transitions and accumulations of the number of steps can be managed on the screen. For example, the walking management software “Walking Style Diary” commercialized by OMRON Corporation can be used as the management software that is actually implemented.

  In the circuit shown in FIG. 9 (c), the circuit of the LED 7 and the count display unit 10 is separated. However, a circuit for detecting the weak current is added to the circuit where the LED 7 is lit. It is also possible to implement. As a power source of the count display unit 10, the battery 12 can be implemented with one or two AA batteries, and when the current generated by the stepping is not detected, the power source is turned off as a power saving mode. You can also.

  FIG. 7 shows a reflection zone picture 1 h printed on the surface of the healthy step 1. With this configuration, it is obvious that which vase corresponds to each organ of the body and is more effective.

  In addition, in the structure of each Example of this invention, it comprises without providing the convex part 6a and the convex part 6b on the surface of the electroconductive part 6A and the electroconductive part 6B, and the opening part 1b of an appropriate magnitude | size is provided in the overlay part 1a. Formed, the sole of the foot is brought into contact with the surfaces of the conductive portion 6A and the conductive portion 6B through the opening 1b, and a weak current is supplied from the surface into the skin tissue of the foot. Also good.

  The effectiveness of the weak current generated by the present invention will be described. A bioelectric current of 100 to 200 μA flows in the body, and the biocurrent is disturbed by the cell tissue, which disturbs the ion arrangement of the cell tissue. If it did not flow smoothly, the natural healing power of humans declined, causing disease. Therefore, it has been reported in the research results of the University of Pittsburgh that a weak current close to the bioelectric current flows from outside the body, and the natural healing power is increased, and there is weak current therapy (microcurrent therapy) as a treatment method. When individual cells or tissues are damaged by current therapy, a weak (= damaged) current is artificially passed from outside the body to generate ATP (adenosine triphosphate) enzyme that supplies the energy necessary for the repair. It has also been proved that protein synthesis is promoted to increase natural healing power and accelerate healing (recovery). According to the research result of the University of Pittsburgh, there is a report that a weak current increases ATP synthesis in cells by 50%, increases protein synthesis by 70%, and increases cell-to-cell transport by 40%. As a weak current treatment device, a weak current generator has been developed and commercialized, and the weak current treatment is originally used by athletes and professional athletes for treatment of bruises and ligament damage. It is known that Beckham player took it into the fracture treatment and healed it in a short period of time. Therefore, the healthy step of the present invention can normalize the organs corresponding to the reflexes of the sole of the foot, and also has a diet effect by improving the function of the gastrointestinal tract.
