1. Structure of magnetic therapeutic apparatus

As shown in FIG. 1, the magnetic treatment device 1 according to the first embodiment includes six solid magnets 320, a first rubber-like elastic body 100 having an elongated shape, and a solid magnet fixing plate 400 provided for determining the first The positioning portion 410 of the fixed position of each solid magnet 320 in the rubber-like elastic body 100; and the joint 500, which is detachably attached to both ends in the longitudinal direction of the first rubber-like elastic body 100.

The solid magnet 320 is fixed to the positioning portion 410 of the solid magnet fixing plate 400 inside the first rubber-like elastic body 100. In this embodiment, the first rubber-like elastic body 100 includes an elongated rod-shaped second rubber-like elastic body 110 and a third rubber-like elasticity having a T-shape slightly longer than the second rubber-like elastic body 110.体 120。 Body 120. The second rubber-like elastic bodies 110 are adjacently joined along the longitudinal direction of the third rubber-like elastic body 120. The six solid magnets 320 are embedded in the third rubber-like elastic body 120 so that a part of each solid magnet 320 is exposed from each of the six opening portions 121 formed in the third rubber-like elastic body 120.

The second rubber-like elastic body 110 includes a core material insertion hole 112 that penetrates the longitudinal direction of the second rubber-like elastic body 110 and can insert the core material 200. Although it is not necessary to provide the core material 200 in the second rubber-like elastic body 110, it is possible to maintain the shape after the magnetic treatment device 1 is bent or bent by being buried along the longitudinal direction in the second rubber-like elastic body 110. Therefore, the core material 200 is preferably provided. "Able to maintain shape" means a change in the shape of an object when a predetermined stress is applied, and after the stress is released, the changed shape is maintained or an arbitrary shape is maintained before the original shape is restored. Without completely reverting to its original shape. The “embedding” described above is merely an example of “setting”, and the core material 200 may not be buried along the longitudinal direction of the second rubber-like elastic body 110, but may be pasted on the surface of the second rubber-like elastic body 110. This point is also the same in the subsequent embodiments.

The core material 200 may be mainly composed of any material having higher rigidity than the second rubber-like elastomer 110. For example, the core material 200 may be made of metal, polycarbonate (PC), polyethylene terephthalate (PET), or the like. form. The core material 200 is more preferably formed mainly of a synthetic resin having a higher shape retention ability than that of PC. Examples of the main synthetic resin constituting the core material 200 include a styrene-butadiene block copolymer and a high-density polyethylene. High-density polyethylene refers to a crystalline polyethylene that does not have a branch and is bonded in a linear manner and has a density of 910 kg / m3 or more (JIS K6748). The bonded body of the core material 200 and the second rubber-like elastic body 110 is referred to as a second subunit 20 in this embodiment. In addition, the core material 200 may be embedded in the third rubber-like elastic body 120 instead of the second rubber-like elastic body 110 or together with the second rubber-like elastic body 110. Here, "mainly" in the above "mainly formed of a synthetic resin having a shape retaining ability higher than that of PC" means a ratio exceeding 50% by volume as a whole. Among them, 50 volume percent may be 50 weight percent.

Examples of the material constituting the second rubber-like elastic body 110 include silicone rubber, polyurethane rubber, isoprene rubber, ethylene propylene rubber, natural rubber, ethylene propylene diene rubber, nitrile rubber (NBR), or benzene. Thermosetting elastomers such as ethylene butadiene rubber (SBR); thermoplastic elastomers such as polyurethanes, esters, styrenes, olefins, butadienes, and fluorine; or their composites. Among the materials exemplified above, silicone rubber is particularly preferable. This is because silicone rubber is excellent in heat resistance and cold resistance, and has less adverse effects on the skin.

The second rubber-like elastic body 110 is joined to the third rubber-like elastic body 120 through a surface (also referred to as a bonding surface) 114 along its longitudinal direction. In this embodiment, the second rubber-like elastic body 110 is configured such that the magnetic powder 340 is dispersed inside. Thereby, compared with the case where only the solid magnet 320 is provided, a higher magnetic effect can be exhibited. In addition, a magnetic effect can be applied to a wider area at a mounting site such as a neck of the magnetic treatment device 1.

A surface layer 113 in which the magnetic powder 340 does not exist is formed on the surface of the second rubber-like elastic body 110 in the circumferential direction. The surface layer 113 is a layer for preventing the magnetic powder 340 dispersed inside the second rubber-like elastic body 110 from being exposed to the outside, and has a function as a magnetic powder protective layer. The thickness t1 of the surface layer 113 is preferably 0.25 mm or more. The surface layer 113 can also be formed in the same manner in a magnetic treatment device according to another embodiment including the second rubber-like elastic body 110. In addition, the magnetic powder 340 may be dispersed inside the third rubber-like elastic body 120. In addition, neither of the second rubber-like elastic body 110 and the third rubber-like elastic body 120 may have the magnetic powder 340 dispersed therein. The same applies to the subsequent embodiments.

The third rubber-like elastic body 120 is formed of the same material as a preferable candidate of the material constituting the second rubber-like elastic body 110, and is particularly preferably formed of a silicone rubber. The third rubber-like elastic body 120 is formed with end surface covering portions 125 a and 125 b that can respectively cover the end surface of one end portion 111 a and the end surface of the other end portion 111 b of the second subunit 20. By covering the end portions 111 a and 111 b with the end surface covering portions 125 a and 125 b, respectively, it is possible to prevent the core material 200 from being detached from the second rubber-like elastic body 110. In addition, since the respective end faces of the end portions 111a and 111b are not exposed, the magnetic treatment device 1 is excellent in terms of appearance.

As shown in FIG. 1D, the solid magnet 320 includes: a flange portion 320a formed in a thickness direction of the solid magnet 320 and having a flattened flat shape; and a head portion 320b having a smaller diameter than the flange portion 320a. And protrudes from one surface of the flange portion 320a. The flange portion 320 a is a flat, substantially cylindrical shape. The head portion 320b is a substantially cylindrical portion having a smaller diameter than the flange portion 320a. The boundary portion 320c of the flange portion 320a and the head portion 320b is preferably a shoulder portion having a gently curved surface. In addition, although the flange portion 320a and the head portion 320b are each substantially cylindrical, the flange portion 320a and the head portion 320b are not limited to a cylindrical shape, and may be, for example, a polygonal prism. The solid magnet 320 may be made of any material, and is preferably a ferrite magnet, a cobalt magnet, a rare earth (e.g., rhenium) magnet, or a composite magnet thereof.

As shown in FIG. 1C, the solid magnet fixing plate 400 in this embodiment is a flat rectangular parallelepiped plate. The solid magnet fixing plate 400 includes a positioning portion 410 for determining a fixing position of the solid magnet 320 on one surface (also referred to as a front surface). Here, six solid magnets 320 are fixed along the longitudinal direction of the solid magnet fixing plate 400 and are fixed in a line. Therefore, the positioning portions 410 are provided at six locations along the length direction of the solid magnet fixing plate 400 and are arranged in a row. The positioning portion 410 may have any shape as long as it can determine the position of the solid magnet 320 in the first rubber-like elastic body 100. In this embodiment, the solid magnet fixing plate 400 includes four claw portions 411 at four positions around each of the positioning portions 410 and the boundary portion 320 c of the solid magnet 320.

As shown in FIGS. 1B and 1C, the claw portion 411 is a hook-shaped claw. When the solid magnet 320 is pressed into the claw portion 411 from the front side of the solid magnet fixing plate 400, the claw portion 411 is deformed so as to open outward, so that the flange portion 320a of the solid magnet 320 can pass through. After that, the claw portion 411 is caught on the shoulder portion (boundary portion 320c) of the head portion 320b. Thereby, the solid magnet 320 is fixed to the solid magnet fixing plate 400. The hook-shaped claws only need to include one or more positioning portions 410. Here, although the claw portion 411 is provided with four claws provided at regular intervals around the solid magnet 320, the claw portion 411 may be provided with two or three, or the solid magnet 320 may be fixed to the solid magnet for more stability. The plate 400 is provided with five or more claws.

As for the arrangement method of the solid magnets 320, a plurality of (here, six) solid magnets 320 may be arranged on a straight line or may be arranged in multiple rows. This point is the same in other embodiments including the solid magnet 320. In this embodiment, the number of solid magnets 320 is six, but it is not limited to six, and may be five or less or seven or more. These points are also the same in the embodiment using the solid magnet 320 in other embodiments described later. In addition, in addition to fixing all of the plurality of solid magnets 320 to one solid magnet fixing plate 400, one or more solid magnets 320 may be fixed to each of the plurality of solid magnet fixing plates 400. The number of solid magnets 320 and the number of solid magnet fixing plates 400 are not particularly limited.

In addition, the solid magnet fixing plate 400 includes pin insertion holes 430 and 431 which are used to mold a mold (more specifically, a lower mold) for molding the third rubber-like elastic body 120 and a solid magnet. An example of a mold joint where the fixing plate 400 is coupled. Although in this embodiment, the mold coupling portion is a pin insertion hole 430, 431 through which a pin protruding upward from the inner bottom surface of the lower mold can be inserted, as long as the mold can be coupled to the solid magnet fixing plate 400, it may have any Shape. For example, when an insertion hole is provided on the mold side, the mold coupling portion may be a convex portion protruding from the solid magnet fixing plate 400.

The solid magnet fixing plate 400 may be composed of any kind of resin such as a thermoplastic resin and a thermosetting resin; any kind of metal such as SUS, aluminum, iron, nickel, zinc, and their alloys; alumina, nitrogen Any kind of ceramic such as silicon; or wood.

Moreover, as another preferable material, resins, such as PC, PET, PE, PP, ABS, which are excellent in flexibility and moldability are mentioned.

The joint 500 is a member capable of changing the length of the magnetic treatment device 1 by attaching to and detaching from both ends in the longitudinal direction of the first rubber-like elastic body 100. Although the magnetic treatment device 1 according to this embodiment can attach and detach two joints 500, only one joint 500 can be detached. By inserting a fitting convex part (also referred to as a “joint fitting male part”) 510 fixed to the joint 500 into the fitting recesses formed on the end face covering parts 125 a and 125 b on both sides of the third rubber-like elastic body 120. (Also referred to as a “joint-fitting female”) 122 so that the joint 500 is connected to the first rubber-like elastic body 100. However, the fitting convex portion 510 may be mounted on the third rubber-like elastic body 120 side, and the fitting concave portion 122 may be provided on the joint 500 side. The joint 500 is preferably made of the same material as the candidate of the constituent material of the solid magnet fixing plate 400 or the third rubber-like elastic body 120. In addition, as other materials used for the joint 500, there may be mentioned any kind of metal such as SUS, aluminum, iron, nickel, zinc, and alloys thereof; and any kind of ceramic such as alumina and silicon nitride. In addition, the joint 500 is only an optional additional option for the magnetic treatment device 1 and is not an essential component.

2. How to use magnetic therapeutic apparatus

FIGS. 2A and 2B are respectively a perspective view showing a state where the magnetic treatment device of FIG. 1A is bent at two places in the longitudinal direction, and a schematic view showing a state where the magnetic treatment device is attached to the neck of the user.

The head portions 320 b of the six solid magnets 320 arranged in a row along the length direction of the magnetic treatment device 1 are partially exposed from the third rubber-like elastic body 120. When the magnetic treatment device 1 is used, the solid magnet 320 is positioned on the rear side (trapezoid muscle side) of the neck 700 of the user. In this way, since the solid magnet 320 can be brought into direct contact with the neck 700, the magnetic effect can be improved compared to the conventional products. In addition, the first rubber-like elastic body 100 is covered with the solid magnet 320 fixed to the solid magnet fixing plate 400. Therefore, the position of the solid magnet 320 embedded in the first rubber-like elastic body 100 can be substantially fixed, and the length of the solid magnet 320 exposed from the first rubber-like elastic body 100 can also be substantially fixed. Therefore, it is also possible to reduce variations in the magnetic effect of each magnetic treatment device 1. Regarding the length of the magnetic treatment device 1, if the disassembly and attachment of the joint 500 described above is also taken into consideration, it is preferable that the length of the magnetic treatment device 1 can be adjusted to approximately wrap around the neck of the user regardless of the adult, the child, the elderly, or the male or female 700 a week in length. In addition, the magnetic treatment device 1 may be formed to have a length such that the ends thereof can be crossed around the neck 700 of the user for more than one week.

3． Manufacturing method of magnetic therapeutic apparatus

After forming the solid magnet fixing plate 400 using a molding method such as injection molding, as shown in FIGS. 4A and 4B, the solid magnet 320 is fixed to the positioning portion 410 of the solid magnet fixing plate 400 to complete the first subunit 10 (see FIG. 5A to 5E). Through this step, the solid magnet 320 and the solid magnet fixing plate 400 can be firmly fixed (first sub-assembly step S10).

When the core material 200 is provided in the second rubber-like elastic body 110, the core material 200 is first inserted into the core material insertion hole 112 of the second rubber-like elastic body 110 manufactured by extrusion molding or the like, so that it can be completed. The second subunit 20 (see FIG. 1). The step which is an optional additional option is referred to as a second sub-assembly step S2. In addition, instead of inserting the core material 200 into the core material insertion hole 112 of the second rubber-like elastic body 110, a method in which the core material 200 and the second rubber-like elastic body 110 are extruded and molded together can be adopted.

Following step S2, the second sub-unit 20 is mounted on the lower mold 620 (second sub-unit mounting step S4).

Next, as shown in FIG. 5A, the pins 625 and 625 protruding from the inner bottom surface of the lower mold 620 are combined with the pin insertion holes 430 and 431 provided in the solid magnet fixing plate 400 to mount the first subunit 10 on the lower portion.

The liquid curable rubber composition MT1 of the elastomer 120 is subjected to injection molding (molding step S30). Alternatively, instead of injection molding, transfer molding or compression molding may be performed (the same is true of injection molding performed in the following embodiments). In this molding step, the temperature of the mold 600 is in a temperature range in which the curable rubber composition MT1 is cured and becomes the third rubber-like elastic body 120.

After the forming step (step S30) is completed, as shown in FIG. 5C, the mold 600 is opened, and the formed article 1 'is taken out from the mold 600 (release step S40).

When the core material 200 is provided in the second rubber-like elastic body 110, in order to further improve the adhesion between the second subunit 20 and the third rubber-like elastic body 120, as shown in FIG. 5D, a clamp for pressing can be used. 630 clamps the molded object 1 'from both sides in the width direction of the molded object 1' (the direction indicated by the blank arrow) and presses it.

After this shape correction step, the formed article 1 'as shown in FIG. 5E is completed, and thereafter, as an optional additional option, the joint 500 can be manufactured. In this case, for example, as shown in FIG. 3, after the joint fitting male part (fitting convex part) 510 is manufactured by injection molding or the like, the joint fitting male part 510 may be placed in a mold and inserted into the mold. The curable composition for producing the joint 500 is supplied and injection molding is performed (third sub-assembly step S60).

Thereafter, the joint 500 is joined to both ends in the longitudinal direction of the molded article 1 '(joint fitting step S70), and the magnetic treatment device 1 is completed. Alternatively, instead of the forming step (S30), the second subunit 20 and the third rubber-like elastic body 120 in which the first subunit 10 is embedded may be pressed and bonded using an adhesive. The same applies to other embodiments.

The magnetic treatment device 1 can be appropriately manufactured by a manufacturing method including at least the steps of fixing the solid magnet 320 to the positioning portion 410 of the solid magnet fixing plate 400 to complete the first sub-assembly step S10 of the first sub-unit 10 to First subunit mounting step of mounting the first subunit 10 in the mold 600 such that one surface in the thickness direction of the solid magnet 320 is exposed and the side opposite to the one surface is covered by the first rubber-like elastic body 100. S20: A molding step step S30 in which the curable rubber-like composition for manufacturing the first rubber-like elastic body 100 is filled in a mold 600 to be molded.

In the case where the core material 200 is inserted into the second rubber-like elastic body 110 with the magnetic powder 340 to manufacture the second subunit 20, it is preferable that the manufacturing method further includes the following steps before the forming step S30, that is, preparing the The second rubber-like elastic body 110 of the core material insertion hole 112 into which the core material 200 for shape retention is inserted, and the core material 200 is inserted into the core material insertion hole 112 to complete the second sub-assembly step S2 of the second subunit 20, wherein The core material 200 is formed of a synthetic resin having a higher shape retaining ability than polycarbonate; and a second subunit mounting step S4 of mounting the second subunit 20 inside the mold 600.

When the solid magnet 320 is intended to be buried in the first rubber-like elastic body 100 so that a part of the solid magnet 320 is exposed from the first rubber-like elastic body 100, how to embed the solid magnet 320 is generally generated. The problem is the exact position of the inside of the first rubber-like elastic body 100. However, according to the manufacturing method described above, the first sub-assembly step S10 and the first sub-unit mounting step S20 can be performed by using the mold coupling portion exemplified as the solid magnet fixing plate 400 and the pin insertion holes 430 and 431, respectively.

In addition, in the second embodiment, the same terms and / or symbols are assigned to the structures that are common to the first embodiment, and the descriptions thereof are replaced with the descriptions in the first embodiment, and redundant descriptions are omitted.

6A, 6B, 6C, and 6D respectively show a perspective view of a magnetic therapy device according to a second embodiment, a bottom perspective view of a first subunit showing a state before a solid magnet is inserted into a solid magnet fixing plate, A partial perspective plan perspective view of the first subunit that fixes the solid magnet to the solid magnet fixing plate, and a cross-sectional view taken along the line AA in FIG. 6A.

Compared to the magnetic treatment device 1 (see FIG. 1) according to the first embodiment described above, the magnetic treatment device 2 according to the second embodiment is formed by a well in a portion corresponding to the positioning portion 410 of the solid magnet fixing plate 400. The shape of the solid magnet insertion portion (an example of the positioning portion) 420 differs in this point, and the structure is the same other than that.

As shown in FIG. 6B, the solid magnet fixing plate 400 has a SF1 side opening on the first surface (back surface in FIG. 6), and corresponds to the shape of the solid magnet 320 and can be inserted into the solid of the solid magnet 320. The magnet is inserted 420. In addition, the solid magnet fixing plate 400 has a second surface (a front surface surface in FIG. 6) SF2 penetrating from the first surface SF1 to the side opposite to the first surface SF1 at the bottom 421 of the solid magnet insertion portion 420.的 孔 孔 422. The solid magnet 320 is inserted into the solid magnet insertion portion 420 from the first surface SF1 side, and is fixed to the solid magnet fixing plate 400 such that the head 320 b is exposed on the second surface SF2 side of the through hole 422. The solid magnet insertion portion 420 has a form (also referred to as a size or a shape) capable of being fitted into the flange portion 320 a of the solid magnet 320. In addition, the through-hole 422 also has a form (also referred to as a size or a shape) that can be fitted into the fixed head 320b. As a result, the solid magnet 320 is reliably fixed to the solid magnet fixing plate 400 by the solid magnet insertion portion 420.

The magnetic treatment device 2 having such a structure can be manufactured by various manufacturing methods. For example, in the first sub-assembly step S10 of the first embodiment, as shown in FIG. 6B, the solid magnet 320 is inserted into the solid magnet insertion portion 420 so that the head portion 320 b of the solid magnet 320 is exposed in the through hole. The solid magnet 320 is fixed to the solid magnet fixing plate 400 on the second surface SF2 side of 422, so that the first subunit 10 can be completed. Alternatively, a claw portion may be provided on the SF1 surface, and the solid magnet 320 may be fitted and fixed to the solid magnet fixing plate 400. As for the other steps, it is basically possible to use the same method as the manufacturing method of the first embodiment.

The solid magnet 320 penetrates the through-hole 422 until the head portion 320b is exposed on the second surface SF2 side of the through-hole 422, and the flange portion 320a is fitted into the solid-magnet insertion portion 420 to be fixed to the solid-magnet fixing plate 400. Therefore, the solid magnet 320 can be more firmly and stably fixed to the solid magnet fixing plate 400. In addition, even if a force of a magnitude that causes the solid magnet 320 to escape to the outside is applied to the magnetic treatment device 2, the through-hole 422 of the solid-magnet insertion portion 420 does not allow the flange portion 320 a of the solid magnet 320 to pass through. The solid magnet 320 is not easily detached from the third rubber-like elastic body 120. (Third Embodiment)

Next, a magnetic treatment device according to a third embodiment will be described.

However, the material of the continuous forming body 450 may be a resin (PC, PE, PP, PET, ABS, etc.) other than a styrene-butadiene block copolymer or a high-density polyethylene stretched body, or a metal (SUS , Aluminum, iron, etc.). Since the continuous formation body 450 is a member connecting the second rubber-like elastic body 110 and the third rubber-like elastic body 120, it contributes to the improvement of the adhesion between the two 110 and 120. This point is the same in other embodiments.

The magnetic treatment device 1 having such a structure can be manufactured by various manufacturing methods. For example, the second sub-assembly step S2 can be performed before the first sub-assembly step S10. In this case, it is only necessary to manufacture the first subunit 10 by inserting the continuous forming body 450 into the second rubber-like elastic body 110 instead of the core material 200, and then fixing the solid magnet 320 and the continuous forming body 450.

The preferred material or other optional materials of the solid magnet fixing plate 400 and the continuous formation body 450 of the core material 200 are the same as those of the third embodiment.

The magnetic treatment device 2 having such a structure can be manufactured by various manufacturing methods. For example, the second sub-assembly step S2 can be performed before the first sub-assembly step S10. In this case, it is only necessary to manufacture the first subunit 10 by inserting the continuous forming body 450 into the second rubber-like elastic body 110 instead of the core material 200, and then fixing the solid magnet 320 and the continuous forming body 450. On the other hand, it is also possible to perform the second sub-assembly step S2 after the first sub-assembly step S10. In this case, the member formed by fixing the solid magnet 320 to the continuous forming body 450 and the second rubber-like elastic body 110 may be formed integrally. The other steps and effects are the same as those described in the third embodiment, and therefore descriptions thereof are omitted. (Fifth Embodiment)

The magnetic treatment device 1 having such a structure can be manufactured by various manufacturing methods. For example, before the first sub-assembly step S10, a step of forming the continuous forming body 450 using the same material may be performed. The steps other than this are the same as those described in the third and fourth embodiments, and therefore descriptions thereof are omitted.

In addition, the continuous forming body 450 may be the above-mentioned one as long as it is at least two or more of the core material 200, the solid magnet fixing plate 400, and a joint portion (whether a concave portion or a convex portion) that can be joined with the joint 500.
