Abstract

[PROBLEMS] To provide a cushion-embedded electro-magnetic therapy device with a thick structure capable of withstanding dynamic loads that cannot be easily seated when installed on a chair. A thick, rigid frame structure is heavy and difficult to move. Dampens and surface magnetism decreases, heat builds up due to thick structure, increases the risk of low-temperature burns, increases cord damage accidents due to exposed cords at multiple seat joints, makes bare type easy to cushion type Since there is no cushion cover to be inserted into the bag, there are problems such as the possibility of an overheating accident caused by the user wrapping with a futon or towel in order to use the naked type as a cushion embedded type. A high density foamed resin is used to facilitate a dynamic load strength, a thin structure, light weight, heat dissipation, cord storage, and a removable cushion cover, and a hole and a magnetic induction plate are arranged in the outer urethane layer. This makes it possible to obtain an appropriate magnetic output. [Selection] Figure 26

Description

  The present invention relates to an electromagnetic therapy device that generates magnetism by electricity.

The definition and related conditions of electro-magnetic therapy device are described.
As an electromagnetism treatment device that generates magnetism by electricity, a home electromagnetism treatment device is known in Japan, and the following definitions are defined in related standards.
1) Treat the affected area by applying an alternating magnetic field to the affected area.
2) The surface magnetic flux density of the part in contact with the affected area shall be 35 to 180 mT.
3) The generated magnetic field is a 50 / 60Hz sine wave.
From this, a general electromagnetism treatment device in Japan uses “sine wave AC of commercial power supply as it is” and generates “50 / 60Hz magnetism of 50Hz or 60Hz AC” by magnetism generating coil. , "Treat the patient with a sine wave magnet by alternating current".

A specific example will be described.
FIG. 1 is a specific example of the prior art (Patent Document 1). The coil 2 and the coil 3 are arranged on the U-shaped iron core 4 and a commercial power source is directly connected to the coil to generate 50 Hz or 60 Hz “sine wave magnetism”.
FIG. 2 shows another specific example (Patent Document 2, FIG. 28). A coil 12 is wound around an H-shaped iron core 11 and a magnetic flux 13 is generated by a current supplied from a power supply 8. Further, in this example, an example (patent delegation 2, FIGS. 11 and 12) in which the magnetism generating portion is incorporated in the cushion is also shown.

FIG. 3 shows an example in which the conventional magnetic generator 14 is incorporated in a magnetic unit 17 and incorporated in a cushion structure seat (seat structure). A cushion structure is formed by the back portion 15, the seat portion 16, and the leg portion 17. In this example, a total of five magnetic generation units 17 are incorporated here. The individual sheets are connected by a connecting cord 18 and a connecting cord 19, and are composed of a common power cord 20 for power supply, a control remote controller 21 for controlling each magnetic unit, and the like. Although the internal structure of the cushion is not shown, a wooden frame, an aluminum frame or the like is generally used as a structural material.

Japanese Patent Laid-Open No. 6-165830 (Term 2, Fig. 1) Japanese Patent Application No. 2015-159518 (FIGS. 11, 12, and 28)

Patent Document 2 refers to cushion incorporation without using a single magnetic generation unit. Such a structure with a built-in cushion has the following problems.
1) Insufficient strength: Because of its thin structure, it is broken by dynamic mechanical forces such as riding and splashing.
2) Thickness increase: Thickness of the cushion increases.
3) Weight increase: The cushion structure that ensures strength and heat dissipation increases in weight.
4) Decrease in magnetic output: The magnetic output on the cushion surface is attenuated by the thickness of the cushion exterior.
5) Internal overheating: The surface temperature of the cushion becomes high, and low temperature burns are likely to occur.
6) Cord exposure: The cord at the connecting part is exposed and the cord is easily scratched by external force.
7) Unit removal: When you want to use the unit alone, the magnetic unit cannot be removed from the cushion.

(1.1) Describe the first issue, “insufficient strength”.
FIG. 4 is an example in which a leather unit is omitted from the exterior, but a magnetic unit is incorporated in a cushion. The bottom plate 23 and the top plate 24 made of plywood or the like are fixed to the upper and lower sides of the wooden frame 22 to form a main structure portion. However, it is necessary to reduce the overall thickness 29 due to market demands for weight reduction and compactness. Insufficient strength. For example, it becomes very difficult to satisfy the dynamic strength when the foot 28 is stepped on or jumped. Actually, when stepping on or jumping up like this, the crack 26 is easily generated and it becomes difficult to maintain the structure, so that it becomes a large size that obtains an appropriate strength to prevent this, and as a result, the weight also increases. This results in an increase in use convenience quality.

(1.2) The second problem, “thickness increase” will be described.
FIG. 5 shows an example of a defect when the size is increased and the thickness is increased to maintain the strength mentioned above. In order to improve the strength, it is necessary to increase the section modulus of the frame structure as a base material. However, it is natural that increasing the thickness direction in the same way as a beam is effective to increase the section modulus efficiently. . As is known, if the width direction is increased without increasing the thickness direction, the weight is increased further in principle. This is an example in which a magnetic therapy device 33 composed of a backrest foot triplet seat is installed on a chair 32, and the height of the seat is increased by strengthening the strength and increasing “h (thickness) 30” to about 15 cm. H31 is raised and it becomes difficult to sit down, and the function of the chair is not satisfied. In some cases, a footrest is required to sit.

(1.3) The third issue “weight increase” will be described.
The h (thickness) 30 in FIG. 5 can be increased to increase the thickness at the expense of convenience of use, and the structural strength can be increased. To do.
As shown in FIG. 6, if the strength is strengthened by, for example, the aluminum angle 34 without increasing the thickness, the thickness does not increase, so that the convenience of use can be maintained, but the weight of the material of the aluminum angle 34 results. And the convenience of light weight is inferior.
Here, it mentions also about the necessity of combined use of steel materials. Reinforcement with aluminum material is inevitable for brittle fracture factors, so it is very difficult to give dynamic strength, and if aluminum material is used in a part where dynamic load is applied like a bicycle frame, the result is dynamic load The risk of eventually breaking due to brittle deterioration due to unavoidable is inevitable. For this reason, inspection is carried out regularly, or in general, steel materials are used together as auxiliary materials, but since the steel materials are heavy, an increase in mass cannot be avoided. There is such a background, and in order to satisfy the dynamic load with a compact size, there is a reality that the combined use of steel is unavoidable in the end. That is, it is unavoidable that it becomes heavy.

(1.4) The fourth problem “decrease in magnetic output” will be described.
FIG. 7 shows an example in which a leather sewing cover 37 is covered. The leather sewing cover 37 has urethane underneath the leather 36 directly below the leather sewing cover 37, and this thickness (the leather directly under urethane thickness D 35) is raised from the surface of the magnetism generation unit 38. As a result, the magnetic flux density decreases due to the magnetic distance attenuation.
FIG. 8 shows this image with a simple magnetic circuit. When the coil 12 is wound around the iron core 41 and connected to the commercial power source 8 to generate the magnetic flux Φ13, the magnetic flux as shown in this figure is generated. The magnetic flux converges from the top of the iron core 41 to the bottom, and the density of the magnetic flux increases on the upper and lower surfaces of the iron core. Of course, the magnetic flux density is high at the point A portion 39 close to the iron core, and the magnetic flux density is low at the point B portion 40 far from the iron core. In other words, since the magnetic output decreases as the distance from the magnetic output unit increases, a structure that does not interpose a structure as thick as possible is preferable.

(1.5) Describe the fifth issue of “internal overheating”.
Description will be made with reference to the cut diagram of FIG. The lower urethane directly below the urethane 36 has a urethane thickness d42 directly below the leather, which becomes a heat insulation barrier, prevents heat dissipation of the internal magnetism generating unit 38, and promotes internal overheating. As a result, by repeatedly operating without leaving the cooling period, the internal overheating progresses to the operating point of the overheat protection device and stops. As the overheat protection device, a thermostat or the like is generally used, and once it operates, the temperature at which it recovers is lower by 10 to 20 ° C, so it takes several hours to cool and reset, depending on the heat dissipation time constant There is a case. In addition, when the overheating temperature is high, the worst case may be low temperature burns. Especially in a thick structure, heat builds up inside, and it takes several hours until it is reset, which tends to increase the risk of low-temperature burns because the surface temperature tends to increase with the passage of time. there were.

(1.6) Describe the sixth issue, “Exposing Code”.
FIG. 3 shows an example of a magnetic therapy device with a built-in cushion. As can be seen, a connecting cord (back seat) 18 and a connecting cord (seat leg) 19 are exposed to the outside. For this reason, there is a possibility of being scratched by being caught in a foreign object or another structure or being stepped on with a foot. In addition, there is a possibility of damaging the internal electric wire by pinching under the main body, and it is in a part that is easily pinched in place, so it has a structure that essentially leaves a possibility of malfunction. is there.

(1.7) The seventh issue “Unit Desorption” will be described.
FIG. 9 shows an example of a magnetic therapy device composed of a single magnetic generation unit. Such a structure having only a single body is a treatment form applied to a local region of the human body. In addition, since it is a naked structure in this form, the part which contacts a human body is hard, and it may become a harsh feeling, and a user will use a towel or cloth purposely. In other words, in order to use the bare type as a cushion type, in extreme cases, it is used by incorporating it in a futon or a commercially available cushion, resulting in misuse such as overheating inside.
FIG. 10 is an example applied to the shoulder. As shown in this example, the treatment form is individually applied pinpoint to each part of the body, such as a shoulder, a waist, and a foot, as an affected part of the human body 43.
FIG. 7 shows an example of a magnetic therapy device in which only one magnetism generating unit is incorporated into a cushion. However, such a cushion-incorporated type cannot perform local pinpoint treatment as described above. For this reason, when it is desired to perform pinpoint treatment, there is an inconvenience that a pinpoint type magnetic treatment device must be purchased separately from the cushion built-in type.

(2.1) An example of means for solving the first problem “insufficient strength” is shown.
FIG. 11 shows a cushioned magnetic therapy device with a flexible structure. Unlike the conventional example, the difference is that a body 48 made of high-density foamed resin is used as a basic base material. Normal urethane has a 50% compressive stress of about 10 kg / m 2, but for example, a base material made of high-density foamed resin is characterized by a compressive stress rate of several tens of times, 100 to 300 kg / m 2. The rigid structural parts are the magnetic output unit 38, the fixed aluminum angle 49, and the heat radiation fixing plate 47, all of which are concentrated in a limited range centering on the magnetic output unit 38. Next, the basic structure is a stepped flexible structure from the outer urethane part to the outer leather sewing part (not shown) through a high-density foamed resin part that has intermediate flexibility between urethane and rigid structure. It is a feature. By such a step-wise flexible structure, a result in which a portion where concentrated stress is generated is reduced as much as possible is obtained.
FIG. 12 shows an example in which a load W is applied by placing a magazine 52 or the like in the lower corner portion of a cushion-embedded magnetic therapy device having such a stepwise flexible structure. In this way, using a material with intermediate deformation characteristics with a compressive deformation stress several tens of times that of urethane, the resulting stepwise flexible structure allows the base material side to deform flexibly against external forces. In this structure, stress is coordinated without generating concentrated stress inside and without causing permanent deformation or destruction of the internal material.

(2.2) The example of the solution of the 2nd subject, "thickness increase" is shown.
FIG. 13 is a schematic example of the section modulus of a simple rectangular structure. In order to obtain strength, increasing the thickness rather than the width of the cross section is more effective in terms of the square, and inevitably results in a thick structure.
On the other hand, in order to obtain strength with a thin structure, a material having a high yield point and a high fracture stress is used. However, a material having high brittleness such as glass cannot be used because concentrated stress management cannot be performed under a dynamic load. For this reason, it will be substantially limited to aluminum, steel, fiber reinforced resin, or the like.

However, a material having a high fracture stress generally lacks flexibility, and as a result, concentrated stress is generated at the joint and the like, and it is still difficult to manage strength enhancement under a dynamic load.
For example, problems of high strength materials such as aluminum will be described. Aluminum is suitable for high strength and light weight, but it is inflexible, brittle, and has the disadvantage of easily causing fatigue failure. For this reason, when a dynamic dynamic load or an impact is applied, it is a dangerous material unless an inspection for fatigue fracture is performed every time the impact is applied. This can be understood from the fact that there are many accidents in which aluminum is used for ladders and bicycle frames and breaks suddenly. In order to avoid this, usually a combination structure with a steel material is often used. As a result, when aluminum is used, periodic inspection is a prerequisite, so it is a difficult material as a security guarantee for general durable consumer products. However, on the other hand, steel is sticky and can withstand most loads, but it is also fatally heavy in this application, so it is also difficult to use in this proposal.

The conventional frame structure shown in FIG. 4 does not bend during dynamic loading, and concentrated stress is generated due to the rigid structure, leading to failure due to insufficient strength. This can be solved if the material is flexible.
FIG. 11 shows an example solved by adopting a flexible material. In this example, as described above, the main base material of the structure uses a high-density foam resin having a high compressive stress indicating intermediate properties between the rigid and the flexible material. It has a stepwise stress reduction structure leading to the structure. By doing in this way, a thin structure can be maintained, without increasing a dimension in the thickness direction.
FIG. 12 is an image view showing a structure in which an external load is released by positively obtaining a deflection and the internal stress is dispersed to prevent stress fracture.

(2.3) An example of means for solving the third problem “weight increase” will be shown.
FIG. 5 shows an example in which h (thickness) 30 is increased to give strength at the expense of convenience of use. Of course, the increase in thickness results in inferior use convenience and an increase in weight.
In FIG. 6, the strength is reinforced by the aluminum angle 34 or the like, but the weight of the additional material increases. Furthermore, as described above, aluminum materials tend to accumulate stress fatigue under dynamic loads, and have a drawback that requires countermeasures.

FIG. 11 shows an example solved by adopting a material that is easily bent. In this example, as described above, the main base material of the structure uses a high-density foam resin having a high compressive stress indicating intermediate properties between the rigid and the flexible material. It has a stepwise stress reduction structure leading to the structure. By doing in this way, a thin structure can be maintained, without increasing a dimension in the thickness direction. That is, the weight can be further reduced with the conventional thickness.
FIG. 12 is an image view showing a structure in which an external load is released by positively obtaining a deflection and the internal stress is dispersed to prevent stress fracture.

(2.4) An example of means for solving the fourth problem “decrease in magnetic output” will be described.
FIG. 7 shows an example in which a leather sewing cover 37 is placed on the magnetic output unit 38. In general, there is a urethane layer immediately below the leather to provide cushioning for maintaining the quality of comfort, and this thickness is raised from the surface of the magnetism generating unit 38. As a result, the magnetic flux density decreases due to the magnetic distance attenuation. (See the magnetic distance attenuation image in Fig. 8)
In FIG. 14, as one solution, a magnetic induction hole (circular) 59 is provided in a chip urethane 50 immediately below the leather. In this example, it is provided immediately above two places where the magnetic output of the magnetism generating unit 38 is strong.
(A), (b), and (c) of FIG. 15 show variations in the shape of the hole, and each shows a circle, an ellipse, and a large collective ellipse. Since the hole is basically formed by making a hole in the strongest part of the surface magnetism of the magnetism generating unit, there are variations in various shapes. However, it is common to consider a size that does not cause uncomfortable internal touch when the human body touches it.
FIG. 16 is an example of the effect of this hole. When a human touches, a cushion such as the chip urethane 50 is pushed in, and the structure can be brought close to the surface of the magnetism generation unit 38 particularly in a portion provided with a hole structure.

FIG. 17 is an example of explanation of the strongest part of surface magnetism. In this example, a main magnetic induction plate 62 and a sub magnetic induction plate 63 each made of a magnetic material are provided immediately above the surface side of the magnetism generating unit 38. As a result, the magnetic flux induced from the surface of the iron core 11 inside the magnetism generating unit is guided to the two magnetic induction plates, and a strong induction-amplified surface magnetism 64 is generated between them. As a matter of course, a hole 59 is made in a corresponding portion of the chip urethane 50 covering the portion where the strong magnetism is generated.

FIG. 18 shows an example in which the edge portion of the magnetic amplification plate is devised. In this example, the direction of the iron core 11 is different from that in FIG. 17, but the direction may be changed by the amplification effect depending on the situation. The main magnetic induction plate (bending acute angle end portion) 65 in this example is an example of an acute angle structure in which a short surface is bent vertically. As a result, the induction-amplified surface magnetism 64 becomes stronger. This is because when the acute angle portion is vertical, not the strong magnetic force in the lateral direction but the magnetic concentration in the vertical direction is increased, resulting in an increase in surface magnetism. On the other hand, the sub-magnetic induction plate 66 arranged at the both ends of the main magnetic induction plate 65 is positioned in accordance with the surface position of the acute angle portion so that the magnetism is concentrated on the acute angle portion of the main magnetic induction plate in this example. It is said.

  FIG. 19 shows an example in which the shape of the above-described sub-magnetic induction plate is a sub-magnetic induction plate (U-shaped) 67. Thereby, since the surface magnetism induced and amplified at the tip of the main magnetic induction plate (bending acute angle end portion) 65 converges from three directions, stronger surface magnetism in the vertical direction can be obtained.

FIG. 20 shows an example in which edge protection blocks 68 that protect the vertical acute angle structure of the secondary magnetic induction plate (U-shaped) 67 are provided at both ends of the secondary magnetic induction plate of FIG. This is a structure that protects an acute angle portion in order to prevent damage to the cushion or the human body due to the acute angle structure when a person touches the cushion. Naturally, the edge protection block is a non-magnetic material that is not affected by magnetism, and is made of, for example, plastic or aluminum.

FIG. 21 shows an example in which a distributed magnetic induction plate 70 made of a magnetic material is disposed not only in the vicinity of the iron core 11 but also in the periphery of the magnetism generating unit 38. One or a plurality of distributed magnetic induction plates 70 are arranged near the surface of the cushion structure to aim at an effect of amplifying the surface magnetism. Actually, the peripheral magnetism is induced and converged by the arrangement of the magnetic material, and there is an effect of generating strong magnetism on the surface side of the magnetic material. As a result, surface magnetism increases.
As a secondary effect, these distributed magnetic induction plates vibrate in response to magnetism because of alternating current magnetism. This vibration also aims at an effect that allows the user to understand that magnetism for magnetic therapy is generated.

22A, 22B, and 22C are examples of different shapes of the above-described distributed magnetic induction plate 70. FIG. Thus, it may be circular, cylindrical, or quadrangular.

FIG. 23 shows an example of a composite type in which a distributed magnetic induction plate is composed of two magnetic induction plates. This is a structure in which the magnetic strength in the vertical direction is increased by concentrating the magnetism from the lower part in the upper acute angle structure part.
FIG. 24 shows an example in which a magnetic induction plate coil 78 is applied to a part of the distributed magnetic induction plate of FIG. In this coil, a current having the same phase as that of the main magnetism is passed, and a supplementary magnetism is generated in a direction to further enhance the surface magnetism. The drive system may be an individual drive circuit or may generate a supplementary magnetism by connecting a plurality of drive circuits in series. However, any drive system may be used as long as it generates a magnetic flux in synchronization with the main magnetic flux.
In this way, it is possible to increase the surface magnetism by providing a magnetic guide plate dispersed in the vicinity of the cushion surface of the magnetic therapy device installed in the cushion, or additionally providing an auxiliary coil. .

(2.5) An example of means for solving the fifth problem “internal overheating” is shown.
It is mentioned that the cushion-mounted magnetic therapy device shown in FIG. 7 has the following overheating problem.
1) Since the magnetism generating unit is covered with urethane or the like, the heat insulating barrier promotes overheating.
2) The return of the thermostat or the like after the protection stop may take several hours.
3) In the worst case, it may develop into a low temperature burn due to overheating.

FIG. 25 shows a solving means. A heat-dissipating aluminum foil 79 is affixed to both sides of the magnetism generating unit 38, and a heat-dissipating aluminum plate 80 also serving as a fixing structure is provided at the bottom. The heat-dissipating aluminum plate that also serves as a fixing may have a strength of, for example, a thickness of 5 mm, provide a fixing hole (not shown), and may also serve as a function of fixing to the high-density foamed resin body 48.
With the above-described structure, the heat generated from the magnetism generating unit is quickly transmitted to the large-area heat-dissipating aluminum foil (for the bottom plate) of the bottom plate, improving the heat dissipation performance and preventing overheating in advance. .

(2.6) An example of means for solving the sixth problem “code exposure” will be described.
In the example of the conventional magnetic treatment device incorporating the cushion in FIG. 3, the connection cords 18 and 19 are exposed to the outside, and there is a possibility that damage or malfunction may occur due to external factors.

FIG. 26 shows an embodiment in which this is solved, and the connecting cords 18 and 19 are accommodated in the connecting structures 81 and 82, respectively.
FIG. 27 is an explanatory view of the connecting structure portion 81 as viewed from the back side (the outer leather is not shown). In this example, the left and right high-density foamed resin bodies 48 have extra cord storage grooves 86, and the extra cord portions are adjusted by these grooves. This connection structure part is connected by a non-display embedded nut or the like embedded in the body with a connection screw 83 or the like, for example. This example is an example of connection between the seat (back portion) 15 and the seat (seat portion) 16, and the portion for storing the cord 18 is described, but the same applies to other portions.
The cord transition 87 in FIG. 27 describes the state of cord transition caused by repeated folding of the sheet or movement of the main body. The transition 87 can be absorbed by the presence of the extra length storage groove 86 described above. Since the extra length storage part can be easily cut into a high-density foamed resin, the use of the high-density foamed resin is still alive here. Here, the cord 18 inside the connection structure portion 81 is bent into an S shape, and two places are constrained by rivets 84 so that the S shape does not collapse. This ensures that the position of the code is not broken inside. Moreover, the cord protection urethane that sandwiches the inner cord protects the cord by dispersing external impact and concentrated stress.
FIG. 28 is an explanatory diagram in which a belt serving as a tension member is configured at both ends so as not to give a direct tensile force to the cord. Reinforcing belts 88 are provided at both ends, and are fixed to the body by, for example, belt fixing screws 89. As a result, even if the back seat and the seat seat are pulled, the pull of both is transmitted through the reinforcing belt 88, so that a large tensile force is not directly applied to the cord.

(2.7) The seventh issue “Unit Desorption” will be described.
FIG. 7 shows an example of cushion incorporation, and it is difficult to locally treat pinpoints.
FIG. 9 shows an application example of a single configuration, which is applied to a local part of the human body as appropriate in a pinpoint manner.
As shown in FIG. 10, for example, it is applied to a local area such as a shoulder in a pinpoint manner. For this reason, when it is desired to perform pinpoint treatment, there is an inconvenience that a pinpoint type magnetic treatment device must be purchased separately from the cushion built-in type.
FIG. 29 is an example in which the above is solved. Using the removable detachable cushion cover 90, it is possible to treat the local area as a pinpoint with a bare single body as needed, or to appropriately store the cushion cover 90 and use it as a cushion type. The cushion cover 90 has a heat radiating structure by a lower base plate 96 and a heat radiating aluminum foil 99 affixed on the bottom plate 96, and a main body is composed of a high density foamed resin body 98.
FIG. 30 is an explanatory diagram of storage. The bare magnetism generating unit 38 is housed in the lower housing groove 101 of the cushion cover 90 and fixed by tightening the fastener 91 so that the upper housing groove is aligned.
With such a configuration, it is possible to use it with a cushion cover as appropriate, or to use it naked or in common.

(3.1) An embodiment for solving the first problem “insufficient strength” will be described.
FIG. 11 shows a cushioned magnetic therapy device with a flexible structure. Unlike the conventional example, a body 48 made of, for example, a high density foamed resin is used as a basic base material. For example, the 50% compressive stress of ordinary urethane is about 10 kg / m 2, but the base material made of the high density foamed resin of the present invention is 100 to 300 kg / m 2 and the compressive stress rate is several tens of times. As a result, the rigid structure has three points, that is, the magnetic output unit 38, the fixed aluminum angle 49, and the heat radiation fixing plate 47, all of which are concentrated in a limited range centering on the magnetic output unit 38. The main structural part is a high density foamed resin body. This body need not be a high-density foamed resin as long as it is flexible and has a considerable strength.
Structural support and connection take into account the balance of stress coordination. Specifically, the structure is sequentially formed from a urethane portion for finally maintaining exterior flexibility through a body made of a high-density foamed resin, to an outer leather sewing portion (not shown). As described above, the basic structure is a stepwise flexible structure. By such a step-wise flexible structure, the portion where the concentrated stress is generated is reduced as much as possible, and the strength against the dynamic load is obtained by eliminating the concentrated stress generating portion.
FIG. 12 shows an example of the effect of applying a load W by placing a magazine 52 or the like on the lower corner of a cushion-embedded magnetic therapy device with a stepwise flexible structure considering such stress coordination. In this way, using a material with intermediate deformation characteristics with a compressive deformation stress several tens of times that of urethane, the resulting stepwise flexible structure allows the base material side to deform flexibly against external forces. In this structure, stress is coordinated without generating concentrated stress inside and without causing permanent deformation or destruction of the internal material. Naturally, it has a strength several tens of times higher than that of urethane, so it can withstand the strength of normal static loads, and it has a structure that distributes stress by bending itself during dynamic loading. .

(3.2) An embodiment for solving the second problem, “thickness increase” will be described.
The conventional frame structure shown in FIG. 4 is not bent during dynamic loading, and concentrated stress is generated due to the rigid structure, and is easily broken by dynamic loading. However, it will be solved if it is a flexible material.
FIG. 13 shows an example of a rectangular section modulus. However, in a thin structure, the strength is reduced by a square and, as a result, a high fracture stress material is required. However, there is a limit, and it is generally heavy and expensive.

FIG. 11 shows an example solved by adopting a flexible material. In this example, a high-density foamed resin with both strength and deflection performance is used for the body part that is the base material, and a stepwise stress reduction structure from rigid structure to flexible structure is also adopted. . As a result, the size is reduced in the thickness direction to realize a thin structure body.
In addition, in this figure, although the leather coating part used as the outermost exterior is not shown in figure, the leather coating which covers the outer periphery is actually performed. As the leather coating, an antibacterial material, a deodorizing material, or a function having a function of emitting far infrared rays may be employed. Further, the leather covering may be fixed by various fixings such as screwing with a nut embedded in the body, a fastener, and adhesion.
The structure is such that a heat-dissipating aluminum foil 46 is attached to a resin bottom plate 45, a heat-dissipating fixing plate 47 made of an aluminum plate or the like, a resin bottom plate 45, a magnetic generating unit 38, and fixed aluminum fixed to both sides of the magnetic generating unit 38. An angle 49 is placed, and is composed of a high-density foamed resin body 48 that covers them. The fixing screw 44 passes through the resin bottom plate 45, the heat radiation fixing plate 47, and the high-density foamed resin body 48 in order, and is fastened to a tap provided on the fixed aluminum angle 49.
As another method, the resin bottom plate 45 may be made of a heat radiating material such as aluminum, and the heat radiating aluminum foil 46 and the heat radiating fixing plate 47 may be eliminated. The fixed aluminum angle is not aluminum, but other materials with good heat dissipation may be used. The fixing screw may be fixed with a heat-dissipating fixing plate, and the fixing aluminum angle 49 may be fixed to the high-density foamed resin body with a binding band or the like, and the long fixing screw may be shortened to eliminate stress concentration in various places. The high density foamed resin body 48 may be made of another flexible material, such as rubber. The chip urethane 50 may be rubber or other cushion material. The heat radiating aluminum foil 46 may be attached to the front and back of the resin bottom plate 45.
The amount of heat generated by the magnetism generating unit 38 is radiated mainly from the resin bottom plate 45 to the outside of the lower part through the fixed aluminum angle 49, the heat radiation fixing plate 47, and the heat radiation aluminum foil 46. On the other hand, heat is also radiated from the upper part of the fixed aluminum angle 49 and the upper part of the magnetism generating unit 38 to the front side, but since there is a chip urethane 50 for comfort on the front side, the heat radiation from the surface is relatively It will be small. These are also considerations for lowering the surface temperature of the front surface and preventing health hazards such as low-temperature burns.

FIG. 12 is an image diagram in which an external load is released by positively obtaining a deflection, and even a thin structure has a structure in which internal stress is dispersed and stress fracture does not occur. In this way, since the frame structure is not made of rigid material, the stress avoidance and stress distribution structure is made by using a flexible material. Even withstand.

(2.3) An embodiment for solving the third problem “weight increase” will be described.
FIG. 5 shows an example in which strength is increased by increasing the thickness, and the convenience of use is inferior and the weight increases.
In FIG. 6, the strength is reinforced by the aluminum angle 34 or the like, but the weight is increased by the additional material.

FIG. 11 shows an example of a solution using a flexible material. The main base material is made of high-density foamed resin, and a thin structure is made possible and weight-reduced as a stepwise stress reduction structure from a rigid structure to a flexible structure.
In addition, in this figure, although the leather coating part used as the outermost exterior is not shown in figure, the leather coating which covers the outer periphery is actually performed. As the leather coating, an antibacterial material, a deodorizing material, or a function having a function of emitting far infrared rays may be employed. Further, the leather covering may be fixed by various fixings such as screwing with a nut embedded in the body, a fastener, and adhesion.
The structure is such that a heat-dissipating aluminum foil 46 is attached to a resin bottom plate 45, a heat-dissipating fixing plate 47 made of an aluminum plate or the like, a resin bottom plate 45, a magnetic generating unit 38, and fixed aluminum fixed to both sides of the magnetic generating unit 38. An angle 49 is placed, and is composed of a high-density foamed resin body 48 that covers them. The fixing screw 44 passes through the resin bottom plate 45, the heat radiation fixing plate 47, and the high-density foamed resin body 48 in order, and is fastened to a tap provided on the fixed aluminum angle 49.
As another method, the resin bottom plate 45 may be made of a heat radiating material such as aluminum, and the heat radiating aluminum foil 46 and the heat radiating fixing plate 47 may be eliminated. The fixed aluminum angle is not aluminum, but other materials with good heat dissipation may be used. The fixing screw may be fixed with a heat-dissipating fixing plate, and the fixing aluminum angle 49 may be fixed to the high-density foamed resin body with a binding band or the like, and the long fixing screw may be shortened to eliminate stress concentration in various places. The high density foamed resin body 48 may be made of another flexible material, such as rubber. The chip urethane 50 may be rubber or other cushion material. The heat radiating aluminum foil 46 may be attached to the front and back of the resin bottom plate 45.
The amount of heat generated by the magnetism generating unit 38 is radiated mainly from the resin bottom plate 45 to the outside of the lower part through the fixed aluminum angle 49, the heat radiation fixing plate 47, and the heat radiation aluminum foil 46. On the other hand, heat is also radiated from the upper part of the fixed aluminum angle 49 and the upper part of the magnetism generating unit 38 to the front side, but since there is a chip urethane 50 for comfort on the front side, the heat radiation from the surface is relatively It will be small. These are also considerations for lowering the surface temperature of the front surface and preventing health hazards such as low-temperature burns.

FIG. 12 is an image view showing a structure in which an external load is released by positively obtaining a deflection and the internal stress is dispersed to prevent stress fracture. Thus, even if it is thin and light, it can be made a flexible product by positively releasing stress by bending. In the example, high-density foam resin is used for the main body, but other materials such as rubber may be used.

In addition, when it exceeds 18 kg in the standard of electrical equipment in Japan, restrictions such as preparing and fixing a grounding wire occur when installing the equipment. This is because the structure of the ground wire is required for safety in the case of heavy objects. On the other hand, since the convenience of movement from room to room decreases when such a fixation is made, electrical equipment is often made so as not to exceed 18 kg. Therefore, in the application of the present plan, it is thin, lightweight and strong so that it does not exceed 18 kg. For example, it is configured using a high-density foamed resin, resulting in exceeding 18 kg. It is often configured so that there is no.

(3.4) An embodiment for solving the fourth problem “decrease in magnetic output” will be described.
In FIG. 7, there is a urethane layer having a cushioning property for maintaining comfort on the upper part of the magnetic output unit 38 that generates magnetism, and the magnetic flux density is reduced by the distance attenuation of this thickness.
In FIG. 14, a magnetic induction hole (circular shape) 59 is provided in the chip urethane 50 immediately below the leather directly above two places where the magnetic output of the magnetism generating unit 38 is strong. As a result, when the user's body is pressed, the hole easily approaches the surface of the magnetic output unit as shown in FIG. It becomes possible to supply to.
(A), (b), and (c) of FIG. 15 show variations of the shape of the hole, and each shows a circle, an ellipse, and a large collective ellipse. Since the hole is basically formed by making a hole in the strongest part of the surface magnetism of the magnetism generating unit, there may be various shape variations. The hole structure may be such that it can be easily brought close to the surface of the magnetism generating unit when the body is worn, and if possible, a hole having a size that does not significantly affect the cushioning property is preferable. That is, it is common to consider a size that does not make the inside shape that is rough when touched by the human body touch.
FIG. 16 is an example of the effect of this hole. When a human touches, a cushion such as the chip urethane 50 is pushed in, and the structure can be brought close to the surface of the magnetism generation unit 38 particularly in a portion provided with a hole structure.
In addition, a cushion material such as a different urethane may be fitted into the hole portion. One example is urethane with low repulsion stress, which can be easily compressed and can easily be reduced in thickness. Of course, a hole, or air layer, is most effective.
Note that the holes may be arranged not only in the strong magnetic part but also in a distributed manner. For example, the holes may be arranged in a matrix so as to give the same effect as the low-rebound urethane as a whole.

FIG. 17 is an example of explanation of the strongest part of surface magnetism. In this example, a main magnetic induction plate 62 made of a magnetic material and auxiliary magnetic induction plates 63 arranged at both ends thereof are provided immediately above the surface side of the magnetism generating unit 38. As a result, the magnetic flux induced from the surface of the iron core 11 inside the magnetism generating unit is guided to the two magnetic induction plates, and a strong induction-amplified surface magnetism 64 is generated between them. As a matter of course, a hole 59 is made in a corresponding portion of the chip urethane 50 covering the portion where the strong magnetism is generated.
In such a main magnetic induction plate and a sub magnetic induction plate, a portion where the magnetism is desired to be amplified may be formed at an acute angle. At this time, it is practically important to secure a distance of about 2 to 6 mm between the two. This is because if this distance is too close, magnetism is attracted uniformly and the magnetism is less likely to concentrate at the acute angle portion.

FIG. 18 shows an example in which the edge portion of the magnetic amplification plate is devised. In this example, the direction of the iron core 11 is different from that in FIG. 17, but the direction may be changed by the amplification effect depending on the situation. The main magnetic induction plate (bending acute angle end portion) 65 in this example is an example of an acute angle structure in which a short surface is bent vertically. Of course, it may be a certain angle even if it is not vertical. As a result, the induction-amplified surface magnetism 64 becomes stronger. This is because when the acute angle portion is vertical, not the strong magnetic force in the lateral direction but the magnetic concentration in the vertical direction is increased, resulting in an increase in surface magnetism. On the other hand, the sub-magnetic induction plate 66 arranged at the both ends of the main magnetic induction plate 65 is positioned in accordance with the surface position of the acute angle portion so that the magnetism is concentrated on the acute angle portion of the main magnetic induction plate in this example. It is said.
In this example, the plane position of the tip of the acute angle portion of the main magnetic induction plate 65 and the surface of the sub magnetic induction plate 66 are almost on the same plane. In general, by doing this, the acute angle part on the same plane becomes a point, and the counterpart secondary magnetic induction plate becomes a plane, so the magnetism concentrates on the point side by adopting a point and plane configuration. It will be. From this, an acute angle portion, that is, a portion that can be regarded as a point, and the other party are made to have a planar configuration. In this example, an acute angle portion is formed on the main magnetic induction plate side, but the acute angle portion may be on the sub magnetic induction plate side.

  FIG. 19 shows an example in which the shape of the above-described sub-magnetic induction plate is a sub-magnetic induction plate (U-shaped) 67. Thereby, since the surface magnetism induced and amplified at the tip of the main magnetic induction plate (bending acute angle end portion) 65 converges from three directions, stronger surface magnetism in the vertical direction can be obtained. Also in this example, the acute angle portion of the main magnetic induction plate and the plane of the sub magnetic induction plate may be substantially matched.

FIG. 20 shows an example in which edge protection blocks 68 that protect the vertical acute angle structure of the secondary magnetic induction plate (U-shaped) 67 are provided at both ends of the secondary magnetic induction plate of FIG. This is a structure that protects an acute angle portion in order to prevent damage to the cushion or the human body due to the acute angle structure when a person touches the cushion. Naturally, the edge protection block is a non-magnetic material that is not affected by magnetism, and is made of, for example, plastic or aluminum.

FIG. 21 shows an example in which a distributed magnetic induction plate 70 made of a magnetic material is disposed not only in the vicinity of the iron core 11 but also in the periphery of the magnetism generating unit 38. One or a plurality of distributed magnetic induction plates 70 are arranged near the surface of the cushion structure to aim at an effect of amplifying the surface magnetism. Actually, the peripheral magnetism is induced and converged by the arrangement of the magnetic material, and there is an effect of generating strong magnetism on the surface side of the magnetic material. As a result, surface magnetism increases.
As a secondary effect, these distributed magnetic induction plates vibrate in response to magnetism because of alternating current magnetism. This vibration also aims at an effect that allows the user to understand that magnetism for magnetic therapy is generated.

22A, 22B, and 22C are examples of different shapes of the above-described distributed magnetic induction plate 70. FIG. Thus, it may be circular, cylindrical, or quadrangular.

FIG. 23 shows an example of a composite type in which a distributed magnetic induction plate is composed of two magnetic induction plates. This is a structure in which the magnetic strength in the vertical direction is increased by concentrating the magnetism from the lower part in the upper acute angle structure part.
FIG. 24 shows an example in which a magnetic induction plate coil 78 is applied to a part of the distributed magnetic induction plate of FIG. In this coil, a current having the same phase as that of the main magnetism is passed, and a supplementary magnetism is generated in a direction to further enhance the surface magnetism. The drive system may be an individual drive circuit or may generate a supplementary magnetism by connecting a plurality of drive circuits in series. However, any drive system may be used as long as it generates a magnetic flux in synchronization with the main magnetic flux.
In this way, it is possible to increase the surface magnetism by providing a magnetic guide plate dispersed in the vicinity of the cushion surface of the magnetic therapy device installed in the cushion, or additionally providing an auxiliary coil. .

(2.5) An embodiment for solving the fifth problem “internal overheating” will be described.
It is mentioned that the cushion-mounted magnetic therapy device shown in FIG. 7 has the following overheating problem.
1) Since the magnetism generating unit is covered with urethane or the like, the heat insulating barrier promotes overheating.
2) The return of the thermostat or the like after the protection stop may take several hours.
3) In the worst case, it may develop into a low temperature burn due to overheating.

FIG. 25 shows a solving means. A heat-dissipating aluminum foil 79 is affixed to both sides of the magnetism generating unit 38, and a heat-dissipating aluminum plate 80 also serving as a fixing structure is provided at the bottom. The heat-dissipating aluminum plate that also serves as a fixing may have a strength of, for example, a thickness of 5 mm, provide a fixing hole (not shown), and may also serve as a function of fixing to the high-density foamed resin body 48.
With the above-described structure, the heat generated from the magnetism generating unit is quickly transmitted to the large-area heat-dissipating aluminum foil (for the bottom plate) of the bottom plate, improving the heat dissipation performance and preventing overheating in advance. . Note that all or part of the outer shell case of the magnetic generation unit 38 may be made of a material having good heat dissipation characteristics such as aluminum. In that case, the aluminum foil stuck on the outer shell is unnecessary.

(2.6) An embodiment for solving the sixth problem “code exposure” will be described.
In the example of the conventional magnetic treatment device incorporating the cushion in FIG. 3, the connection cords 18 and 19 are exposed to the outside, and there is a possibility that damage or malfunction may occur due to external factors.

FIG. 26 shows an embodiment in which this is solved, and the connecting cords 18 and 19 are accommodated in the connecting structures 81 and 82, respectively.
FIG. 27 is an explanatory view of the connecting structure portion 81 as viewed from the back side (the outer leather is not shown). In this example, the left and right high-density foamed resin bodies 48 have extra cord storage grooves 86, and the extra cord portions are adjusted by these grooves. This connection structure part is connected by a non-display embedded nut or the like embedded in the body with a connection screw 83 or the like, for example. This example is an example of connection between the seat (back portion) 15 and the seat (seat portion) 16, and the portion for storing the cord 18 is described, but the same applies to other portions.
The cord transition 87 in FIG. 27 describes the state of cord transition caused by repeated folding of the sheet or movement of the main body. The transition 87 can be absorbed by the presence of the extra length storage groove 86 described above. Here, the cord 18 inside the connection structure portion 81 is bent into an S shape, and two places are constrained by rivets 84 so that the S shape does not collapse. This ensures that the position of the code is not broken inside. Moreover, the cord protection urethane that sandwiches the inner cord protects the cord by dispersing external impact and concentrated stress.
FIG. 28 is an explanatory diagram in which a belt serving as a tension member is configured at both ends so as not to give a direct tensile force to the cord. Reinforcing belts 88 are provided at both ends, and are fixed to the body by, for example, belt fixing screws 89. The belt is made of a material that does not stretch when pulled. As a result, even if the back seat and the seat seat are pulled, the pull of both is transmitted through the reinforcing belt 88, so that a large tensile force is not directly applied to the cord.
In this example, the belt is used, but a rope or a string may be used. The belt is also arranged at both ends, but may be at both ends and the center, or only at the center. You may comprise a connection structure part itself with the material which does not spread.

(2.7) An embodiment for solving the seventh problem “unit removal” will be described.
FIG. 7 shows an example of cushion incorporation, and it is difficult to locally treat pinpoints.
FIG. 9 shows an application example of a single configuration, which is applied to a local part of the human body as appropriate in a pinpoint manner.
As shown in FIG. 10, for example, it is applied to a local area such as a shoulder in a pinpoint manner. For this reason, when it is desired to perform pinpoint treatment, there is an inconvenience that a pinpoint type magnetic treatment device must be purchased separately from the cushion built-in type.
FIG. 29 is an example in which the above is solved. Using the removable detachable cushion cover 90, it is possible to treat the local area as a pinpoint with a bare single body as needed, or to appropriately store the cushion cover 90 and use it as a cushion type. The cushion cover 90 has a heat radiating structure by a lower base plate 96 and a heat radiating aluminum foil 99 affixed on the bottom plate 96, and a main body is composed of a high density foamed resin body 98.
FIG. 30 is an explanatory diagram of storage. The bare magnetism generating unit 38 is housed in the lower housing groove 101 of the cushion cover 90 and fixed by tightening the fastener 91 so that the upper housing groove is aligned.
With such a configuration, it is possible to use it with a cushion cover as appropriate, or to use it naked or in common.
