JP 2007-111322 A

  The above-described health appliances are required to be light in weight in order to reduce the burden on the body when worn. However, in the conventional device, the magnetic part is composed of a rubber magnet, which is a magnetic body having a specific gravity larger than that of the polyurethane layer, in addition to the relatively lightweight polyurethane layer. Since it has a length that surrounds the entire circumference, further weight reduction is required.

  In view of such circumstances, an object of the present invention is to provide a magnetic therapy device capable of reducing the weight of the entire device while ensuring a magnetic effect on the body.

  The invention according to claim 1 for solving the above-mentioned problem is a magnetic therapy device used for a necklace or the like and exerting blood circulation promoting action on the body, and is composed of a resin and a plurality of magnetized solid particles. A long magnetic part having flexibility is provided, and the plurality of solid objects are arranged at positions separated from each other in a state of being covered with the resin (claim 1).

  According to the present invention, a solid material, which is a magnetic body having a specific gravity greater than that of the resin, is only disposed at positions spaced apart from each other with respect to a relatively light weight resin. It is possible to reduce the weight of the entire device while securing the blood circulation promoting action to the body by the object.

  Further, in the present invention, the plurality of solid objects may be arranged between the shoulders of the user when each of the solid objects is behind the user's neck when the magnetic part is mounted around the user's neck. It is preferable that they are arranged so as to be located respectively in the extending portions (claim 2).

  In this way, the weight can be further reduced, and when the magnetic treatment instrument is worn around the neck, the magnetism can be effectively applied to the region between the user's shoulders. It becomes possible.

  In the present invention, a locking portion formed at one end of the magnetic portion, and a locked portion formed at the other end of the magnetic portion and detachably locked with the locking portion. In addition, it is preferable that the locked portion is locked to the locking portion to form a ring shape (Claim 3).

  In this way, the magnetic treatment instrument can be easily attached to the user's neck, arm, etc., and convenience is improved.

  Moreover, in this invention, it is preferable that resin which comprises the said magnetic part is a silicone resin (Claim 4).

  The specific material of the resin constituting the magnetic part is not particularly limited. However, if a silicone resin that is physiologically stable is used, the magnetic part is directly in contact with the skin. It is possible to more reliably suppress the adverse effect of the part on the skin.

  On the other hand, if the magnetic part is made of urethane rubber or nitrile butadiene rubber having relatively high wear resistance and strength, damage to the magnetic part can be suppressed and durability can be improved. ).

  In addition, as a method of manufacturing the magnetic treatment instrument as described above, a resin setting step of setting the resin in a mold having an upper mold and a lower mold corresponding to the magnetic part, and a method of setting the mold in the mold Preferably, the method includes an embedding step of embedding the plurality of solid materials in positions spaced apart from each other, and a press molding step of press molding the resin by the mold (Claim 6).

  If it does in this way, it will become possible to arrange | position the said some solid substance comparatively easily in the predetermined position in resin.

  Here, the solid material magnetized in advance may be embedded in the resin, but if the solid material is magnetized after the embedding step or the press molding step, The magnetic pole directions can be easily made the same (claim 7).

  As described above, according to the present invention, it is possible to provide a magnetic treatment instrument that can be reduced in weight while ensuring the magnetic effect on the body and that can simplify the manufacturing process.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Here, the case where the magnetic therapy apparatus based on this invention is utilized as a magnetic necklace is demonstrated.

  FIG. 1 is a front view of a magnetic therapy device, that is, a magnetic necklace according to the present invention.

  The magnetic necklace 1 has a long magnetic part 10, a locked part 30, and a locking part 50.

  The magnetic unit 10 is applied around the user's neck to cause magnetism to act on the user's body. In the magnetic necklace 1, the magnetic part 10 is configured by embedding a plurality of magnets (solid matter) 14 in silicone rubber (resin) 200, and the magnet 14 causes magnetism to act on the user's body.

  As shown in FIG. 1, the magnets 14 are granular and are arranged at positions separated from each other while being covered with the silicone rubber 200. In the present embodiment, when the magnetic necklace 1 is mounted around the neck with the locking portion 50 and the locked portion 30 described below as the front, each magnet 14 is positioned on the back side of the user's neck. Is provided. Specifically, seven magnets 14 are arranged at equal intervals from each other at positions between both shoulders of the user, so that magnetism effectively acts on the shoulder and neck of the user. Although the kind of this magnet 14 is not specifically limited, It is preferable to use rare earth magnets, such as a neodymium magnet with comparatively strong magnetism.

  The magnetic part 10 has flexibility as a whole due to the elasticity of the silicone rubber 200, and can be used without damaging the body even during exercise. Further, in the magnetic part 10, the magnet 14 is embedded in the silicone rubber 200 in a state of being surrounded by the silicone rubber 200 so that the outer peripheral surface thereof is constituted by the silicone rubber 200. Here, it is said that the silicone rubber 200 is physiologically stable compared to other synthetic resins and the like, and has a relatively small adverse effect on the body. Therefore, when the magnetic necklace 1 is used so as to be in direct contact with the skin, the physiologically stable silicone rubber 200 comes into contact with the skin, so that adverse effects on the user's skin are suppressed.

  The locked portion 30 is locked by a locking portion 50 described later. The locked portion 30 includes a holding portion 31 and a locked protrusion 40. The holding portion 31 is made of silicone rubber 200 and is press-molded integrally with the magnetic portion 10 at one end of the magnetic portion 10.

  The locked protrusion 40 is for holding the magnetic necklace 1 in a ring shape by engaging with a locking hole 51 of a locking portion 50 described later. The locked protrusion 40 has a fixed plate 42, a shaft portion 44 extending from the end surface of the fixed plate 42, and a spherical end portion 46 provided at the tip of the shaft portion 44. Here, the fixed plate 42 is a plate-like member having a sufficiently larger outer diameter than the shaft portion 44, and the spherical end portion 46 is a substantially hemisphere having an outer diameter larger than the outer diameter of the shaft portion 44. It is a shaped member. The fixing plate 42, the shaft portion 44, and the spherical end portion 46 are formed integrally with each other, and are made of, for example, a hard elastomer or polyacetal. The locked protrusion 40 is configured such that a part of the shaft portion 44 extends from the end surface of the holding portion 31 by accommodating a part of the fixing plate 42 and the shaft portion 44 inside the holding portion 31. Is held by the holding portion 31 in a protruding state.

  The locking portion 50 is for locking the locked portion 30. The locking portion 50 is made of silicone rubber 200, and is integrated with the magnetic portion 10 by press molding at the end of the magnetic portion 10 opposite to the portion where the locked portion 30 is provided. Is formed. The locking portion 50 is formed with a locking hole 51 that opens on the end surface opposite to the magnetic portion 10. And this latching | locking part 50 latches the said to-be-latched part 30 because the said latching protrusion 40 and the said locking hole 51 engage.

  Specifically, the locking hole 51 includes an entrance portion 52 that opens to the end face of the locking portion 50, a narrow portion 54 that is provided at a position deeper than the entrance portion, and a depth deeper than the narrow portion 54. The engagement hole 56 is provided at a position. The inner diameter of the narrow portion 54 is set to be larger than the outer diameter of the shaft portion 44 of the locking projection 40 and smaller than the outer diameter of the spherical end portion 46 of the locking projection 40. On the other hand, the outer diameter of the entrance 52 and the outer diameter of the engagement hole 56 are larger than the outer diameter of the spherical end 46 of the locking projection 40.

  As shown in FIG. 3, the locking portion 50 is inserted into the engagement hole 56 while the spherical end portion 46 of the locked projection 40 pushes the narrow portion 54 of the locking hole 51. Thus, the spherical end portion 46 is prevented from coming off by the stepped portion of the narrow portion 54 and the engagement hole 56, and the locked projection 40 is locked.

  Here, as described above, the inner diameter of the narrow portion 54 is set to be smaller than the outer diameter of the spherical end portion 46 so as to prevent the spherical end portion 46 of the locked projection 40 from coming off. The size is set such that the retaining state can be released by applying a relatively small force to the locked protrusion 40. That is, in the magnetic necklace 1, the locked protrusion 40 and the locked portion 30 can be easily attached to and detached from the locking portion 50, and the magnetic necklace 1 can be easily attached and detached. It is configured to do so.

  Next, a method for manufacturing the magnetic necklace 1 will be described. FIG. 4 is a schematic front view of a mold 100 for molding the magnetic necklace 1. Specifically, the mold 100 includes an upper mold 102 and a lower mold 104 that are symmetrical to each other, and FIG. 4 is a schematic front view of the lower mold 104. 5 and 6 are partially enlarged sectional views of FIG.

  The mold 100 includes a magnetic portion groove 110 corresponding to the magnetic portion 10, a locked portion groove 130 corresponding to the holding portion 31 of the locked portion 30, and a locking portion corresponding to the locking portion 50. A stop groove 150 is formed. In addition, the mold 100 is connected to the locked portion groove 130, and the locked protrusion installation groove 140 for setting the locked protrusion 40 over the locked portion groove 130. Is formed. Further, the metal mold 100 is provided with a locking portion metal fitting 151 having an outer shape corresponding to the inner shape of the locking hole 51 of the locking portion 50.

  The manufacturing method of the magnetic necklace 1 using the mold 100 configured as described above includes the following steps.

1) Resin setting step This step is a step of setting the pasty silicone rubber 200 on the mold 100. In this step, the silicone rubber 200 is simultaneously set in each magnetic part groove 110, each locked part groove 130, and each locking part groove 150 of the upper mold 102 and the lower mold 104. Here, before the silicone rubber 200 is set in the locking portion groove 150, the locking portion metal fitting 151 is installed in the locking portion groove 150 of the lower mold 104 in advance, and the locking portion The silicone rubber 200 is prevented from entering the portion corresponding to the 50 locking holes 51. As the silicone rubber 200, for example, a millable silicone rubber may be used.

2) Locked protrusion embedding process This process is a process of embedding the locked protrusion 40 in the silicone rubber 200. In this step, as shown in FIG. 7, a previously formed locked protrusion 40 is disposed along the locked protrusion installation groove 140, and the fixed portion 46 and the shaft of the locked protrusion 40 are arranged. Part of the portion 44 is embedded in the locked portion groove 130 in which the silicone rubber 200 is set. At this time, the locked protrusion 40 is disposed so that the shaft portion 44 protrudes outward from the locked portion groove 130.

3) Magnetic body charging step This step is a step of placing the magnet 14 in the magnetic part groove 110 in which the silicone rubber 200 is set. In this step, as shown in FIG. 8, the magnets 14 are embedded in the silicone rubber 200 set in the magnetic groove 110 of the lower mold 104 at equal intervals. At this time, each magnet 14 is disposed at a position where the silicone rubber 200 is interposed between each magnet 14 and the magnetic part groove 110 of the lower mold 104.

4) Magnetization step This step is a step of magnetizing the plurality of magnets 14. In this step, each magnet 14 is magnetized by a predetermined magnetization power supply device. At this time, each magnet 14 is magnetized so that the magnetic pole directions thereof are the same.

5) Press molding process This process is a process of press molding the silicone rubber 200. In this step, as shown in FIG. 9, the lower mold 104 containing the silicone rubber 200 in which the locked protrusion 140 and the magnet 14 are embedded, and the upper mold on which the silicone rubber 200 is set. Combine with 102 and heat and pressurize. For example, a pressure of 8.5 t is applied at a temperature of 160 ° C.

  When heated and pressurized in this manner, in the magnetic part groove 110, the silicone rubber 200 of the upper mold 102 and the silicone rubber 200 of the lower mold 104 are integrated in a state where the magnet 14 is housed inside, The magnetic part 10 is formed. Further, in the locked portion groove 130, the silicone rubber 200 of the upper mold 102 and the silicone rubber 200 of the lower mold 104 are integrated with the locked protrusion 40 accommodated inside, and the locked The locked portion 30 in a state where the protrusion 40 is held is formed. And in the said latching | locking part groove | channel 150, the silicone rubber 200 of the upper mold | type 102 and the silicone rubber 200 of the lower mold | type 104 are integrated in the state in which a part of the said metal fitting 151 for latching | locking parts was accommodated inside. A locking portion 50 is formed. At this time, the locking part 50 and the locked part 30 are simultaneously molded integrally with the magnetic part 10.

6) Finishing step This step is a step of removing the excess silicone rubber 200 and the like and adjusting the shape of the magnetic necklace 1. In this step, excess silicone rubber 200 extruded around each groove of the mold 100 during the press molding step is eliminated. Further, the locking portion metal 151 is removed from the locking portion 50. As described above, the metal fitting 151 for the locking portion has a shape corresponding to the locking hole 51 of the locking portion 50, and therefore, when the metal fitting 151 for the locking portion is removed, The locking hole 51 is formed.

  In this manner, the magnetic portion 10 including the magnet 14 and made of the silicone rubber 200, the locked portion 30 and the locking portion 50 integrated with the magnetic portion 10, and the locking protrusion 40 are provided. Is held by the locked portion 30, and the magnetic necklace 1 in which the locking hole 51 is formed in the locking portion 50 is formed.

  As described above, according to the magnetic necklace 1, the magnet 14 causes magnetism to act on the body, and the long magnetic part 10 to be mounted around the neck or the like has the plurality of magnets 14 on the silicone rubber 200. By being configured by being embedded at positions separated from each other, the overall weight is reduced as compared with the case where rubber magnets are provided over the entire magnetic portion 10 as in the prior art.

  In addition, the plurality of magnets 14 are arranged only at positions corresponding to the back side of the user's neck and between the user's shoulders, so that the magnetic necklace 1 can be more securely attached. The weight can be reduced, and the magnetism of the magnet 14 can be effectively applied to a portion extending between the shoulders of the user.

  Moreover, if the above methods are used as a method of manufacturing the magnetic necklace 1, the plurality of magnets 14 can be easily arranged at predetermined positions in the silicone rubber 200 in the embedding step. Furthermore, if the magnets 14 are magnetized after the embedding process, the magnetic pole directions of the magnets 14 can be made to coincide with each other, and the magnetism of the magnets 14 can be applied more uniformly to the body.

  Here, after the locked portion 30 is molded, the locked protrusion 40 may be attached to the locked portion 30, but as described above, in the locked protrusion embedding step. Then, if the pressing process is performed after the locked protrusion 40 is embedded, the locked protrusion 40 can be easily held by the locked portion 30, and the locked protrusion 40 is separately provided. It is possible to save the trouble of attaching the to the locked portion 30.

  Further, in the manufacturing method, a member that evaporates and disappears at the time of press molding may be used instead of the locking portion metal 151. In this way, the trouble of removing the locking part metal fitting 151 is reduced.

  Further, the magnetic material charging step may be performed before the locked protrusion embedding step. Furthermore, the magnetizing step may be performed after the pressing step.

  Moreover, the magnetic treatment instrument according to the present invention can be used as appropriate in addition to the magnetic necklace worn around the neck as described above.

  Moreover, the specific structure of the said latching | locking part 50, the to-be-latched part 30, the said to-be-latched protrusion 40, arrangement | positioning of the said magnet 14, etc. are not restricted above. Further, the material or the like of the locked protrusion 50 is not limited to the above. Moreover, the pressure in the press molding process is not limited to the above.

  Furthermore, instead of the silicone rubber 200, urethane rubber or nitrile butadiene rubber may be used. Since this urethane rubber and nitrile butadiene rubber have high wear resistance and strength, the use of these materials suppresses damage to the magnetic necklace 1 and improves durability. Of course, instead of these silicone rubber, urethane rubber, and nitrile butane diene rubber, other synthetic resins or natural resins may be used. However, as described above, since silicone rubber is physiologically stable, adverse effects on the user's skin can be more reliably suppressed by using this silicone rubber.

  Moreover, you may make it comprise the said magnetic part 10, the latching | locking part 50, and the to-be-latched part 30 with separate resin. In this case, what is necessary is just to set each resin to the part corresponding to each part of the said metal mold | die 100 in the said resin setting process.
