FIG. 1 is a plan view showing a magnetic treatment tool (engaged state) according to a first embodiment of the present invention. FIG. 2 is a front view showing the magnetic treatment tool (opened state) according to the first embodiment of the present invention.
The magnetic treatment tool 1 of the present embodiment includes a soft cord-like body 10 and anisotropic magnets (magnets) 20 a and 20 b which are an example of a magnet housed inside the soft cord-like body 10. The magnetic treatment tool 1 is formed on one end side and the other end side of the flexible cord-like body 10, and has a clasp portion 30 for detachably connecting the ends of the flexible cord-like body.

  The clasp portion 30 is composed of a first clasp portion 30A formed on one end side of the soft cord-like body 10 and a second clasp portion 30B formed on the other end side of the soft cord-like body 10 There is. The first clasp portion 30A and the second clasp portion 30B are engaged with each other to form a ring (engaged state) as shown in FIG. The magnetic treatment tool 1 forming a ring is used as, for example, a magnetic necklace or a magnetic bracelet.

  The cross-sectional shape perpendicular to the longitudinal direction of the flexible cord-like body 10 is circular in this embodiment, but as long as it can be bent, the cross-sectional shape is not particularly limited, and may be, for example, elliptical or polygonal. . The diameter of the flexible cord-like body 10 is not particularly limited, but, for example, in the range of 0.3 cm or more and 2 cm or less. Further, the length in the longitudinal direction of the flexible string-like body 10 is not particularly limited, but for example, the range of 30 cm to 70 cm is preferable for the one used as a necklace, and 10 cm for the one used as a bracelet The range of not less than 30 cm is preferable.

  The flexible cord-like body 10 is composed of a plurality of divided bodies 16, 16 ... which can be connected to each other along the longitudinal direction. Each of the divided bodies 16, 16... Is formed with a connecting means 17 (see FIG. 3) for connecting the ends of the divided bodies 16 to one another, and the connecting means 17 forms a series of flexible cord-like bodies 10. In the embodiment shown in FIG. 1, an example is shown in which the flexible cord-like body 10 is constituted of 21 divided bodies 16, 16.

  FIG. 3A is an enlarged cross-sectional view along the longitudinal direction in a state in which the magnetic therapeutic device of the present embodiment is divided into divided bodies. FIG.3 (b) is each expanded sectional view in the A-A 'line in FIG. 3 (a), a B-B' line, and a C-C 'line. FIG.3 (c) is an expanded sectional view which shows the connection part of the division bodies of the state connected by the connection means. In FIG. 3, the longitudinal direction (X direction in FIG. 3) is shortened to clarify the main part.

  The divided bodies 16, 16 ... constituting the flexible string-like body 10 do not contain the first divided body 16A containing the anisotropic magnets 20a and 20b inside, and the second part 16A does not contain the anisotropic magnets 20a and 20b inside. It is comprised from the division body 16B. In the present embodiment, the first clasp portion 30A and the second clasp portion 30B (see FIGS. 1 and 2) are respectively provided to the second divided members 16B and 16B that constitute one end side and the other end side of the flexible string-like body 10 It is formed.

  The end portions of the longitudinal direction (X direction in FIG. 3) of the divided members 16 are connected to the first divided members 16A and the second divided members 16B constituting the divided members 16 to form a series of flexible cords 10 A connecting means 17 is provided for this purpose. The connecting means 17 is composed of an insert 17A having a spherical member 17Ab fixed to the tip of a rod-like member 17Aa, a tubular hole 17Ba for receiving the insert 17A, and a receiver 17B having a spherical hole 17Bb connected thereto. There is.

  In this embodiment, either of the insert 17A or the receiver 17B is used in the split bodies 16, 16 (second split bodies 16B, 16B) that constitute one end side and the other end side of the flexible string-like body 10 The insert 17A and the receiver 17B are respectively formed on the divided bodies 16, 16 ... other than the one end side and the other end side of the flexible cord-like body 10 which is formed.

  The connection means 17 of the present embodiment fits the spherical hole 17Bb of the insertion body 17A into the spherical hole 17Bb while spreading out the tubular hole 17Ba of the receiving body 17B having an inner diameter smaller than the diameter of the spherical member 17Ab. The plurality of divided bodies 16 can be connected along the longitudinal direction (X direction in FIG. 3) (see FIG. 3C).

  The first divided body 16A includes a joined region 16E in which a first string-like member 11 and a second string-like member 15 extending in the longitudinal direction are joined. It is preferable that the 1st string-like member 11 and the 2nd string-like member 15 are formed from soft resin. As the soft resin, rubber and elastomer can be used. Examples of the rubber include silicone rubber, urethane rubber, butadiene rubber, isoprene rubber, acrylic rubber, chloroprene rubber and fluororubber. Examples of the elastomer include styrene-based elastomers, olefin-based elastomers, vinyl chloride-based elastomers, urethane-based elastomers and amide-based elastomers. The first cord-like member 11 and the second cord-like member 15 may be formed of different soft resins, but are preferably formed of the same kind of soft resin from the viewpoint of bonding strength. In the present embodiment, silicone rubber is used for both the first string-like member 11 and the second string-like member 15.

  The first cord-like member 11 has a concave magnet support 12 indented in a concave shape from a joint surface to be joined to the second cord-like member 15, and at least a part of the anisotropic magnets 20a and 20b is a concave magnet support 12 Is inserted in the In the present embodiment, a portion of 50% by volume or more of the anisotropic magnets 20 a and 20 b is inserted into the concave magnet support 12. Since the anisotropic magnets 20a and 20b are inserted into and supported by the concave magnet support 12, the arrangement positions of the anisotropic magnets 20a and 20b are less likely to shift, and the orientations of the anisotropic magnets 20a and 20b or The spacing can be arranged more accurately.

  The opening size of the concave magnet support 12 is preferably the same as or slightly narrower than the size of the bottom surface of the anisotropic magnets 20 a and 20 b (the lower surface on the side inserted into the concave magnet support 12). In this case, the retentivity of the concave magnet support 12 and the anisotropic magnets 20a and 20b is enhanced, so that the arrangement position of the anisotropic magnets 20a and 20b does not easily shift, and the orientation of the anisotropic magnets 20a and 20b or The spacing can be accurately arranged. However, if the opening size of the concave magnet support 12 is too narrow, it may be difficult to insert the anisotropic magnets 20 a and 20 b into the concave magnet support 12. Therefore, the opening size of the concave magnet support 12 is preferably 95% or more of the size of the bottom surface of the anisotropic magnets 20a and 20b.

  In the present embodiment, the joined region 16E of the first string-like member 11 has the convex portion 13 in which the cross-sectional central region is raised more than the cross-sectional peripheral region, and the concave magnet support portion 12 is provided on the convex portion 13. ing. In the present embodiment, the sectional shape of the convex portion 13 is a trapezoidal shape in which the upper base is shorter than the lower one. By providing the convex portion 13, the depth of the concave portion of the concave magnet support portion 12 is deepened, and the retention of the first string-like member 11 to the anisotropic magnets 20a and 20b is improved.

  For this reason, the arrangement positions of the anisotropic magnets 20a and 20b are less likely to be shifted due to bending of the flexible string-like body 10, and the directions and the intervals of the anisotropic magnets 20a and 20b can be arranged more accurately. Further, by providing the convex portion 13, the bonding area between the first string-like member 11 and the second string-like member is increased, so the retention strength between the first string-like member 11 and the second string-like member 15 is improved. It can be done.

  The second string-like member 15 has a concave magnet housing portion 14 formed in a concave shape in the surface to be joined to the first string-like member 11, and at least a part of the anisotropic magnets 20a and 20b is a concave magnet housing portion 14 Housed in The anisotropic magnets 20 a and 20 b are accommodated in the concave magnet accommodating portion 14, whereby the holding force between the second string member 15 and the anisotropic magnets 20 a and 20 b is improved. For this reason, the arrangement positions of the anisotropic magnets 20a and 20b are further difficult to shift, and the directions and the intervals of the anisotropic magnets 20a and 20b can be arranged with higher accuracy. In addition, the bonding force between the first string-like member 11 and the second string-like member 15 becomes strong.

  The outer side part along the longitudinal direction (X direction in FIG. 3) rather than the joined body area | region 16E of 16 A of 1st divisions is formed only by the 1st string-like member 11. As shown in FIG. That is, in a predetermined range on the center side along the longitudinal direction from both ends of the joined region 16E, the ratio of the second string-like member 15 gradually decreases toward the outside along the longitudinal direction, and both ends of the joined region 16E The ratio occupied by the second string-like member 15 is eliminated.

  With such a configuration, the insert 17A and the receiver 17B constituting the connecting means 17 of the first divided body 16A, which are located on the outer side along the longitudinal direction than the joined body region 16E, are only the first cord-like members 11 It consists of In addition, the outer side part along the longitudinal direction rather than the joined body area | region 16E of the 1st division body 16A can also be comprised only with the 2nd string-like member 15 contrary to this embodiment.

  In the present embodiment, the second divided body 16B constituting the divided body 16 is a string-like body entirely formed only of the first string-like member 11, and the anisotropic magnets 20a and 20b are not accommodated inside. In the second divided body 16B, an insertion body 17A and a receiving body 17B which constitute the connecting means 17 are formed at both ends. In the present embodiment, either the insert 17A or the receiver 17B is formed in the second divided members 16B and 16B constituting one end side and the other end side of the flexible cord-like body 10, and the insert A first clasp portion 30A and a second clasp portion 30B (see FIGS. 1 and 2) are formed at the end opposite to the side where the 17A or the receiver 17B is formed.

  Such a second divided body 16B can be arbitrarily changed in combination of arrangement depending on the application, such as a necklace type or a bracelet type. That is, the anisotropic magnets 20a and 20b prepare the required number of first divided bodies 16A accommodated, and connect the second divided bodies 16B to an arbitrary number so as to obtain the desired overall length, thereby making the magnetic It is possible to easily form the magnetic therapeutic device 1 having the required number of anisotropic magnets 20a and 20b for exhibiting the therapeutic effect, and having the desired overall length.

  In the present embodiment, the first clasp portion 30a and the second clasp portion 30b formed on the second divided members 16B and 16B constituting the one end side and the other end side of the flexible cord-like body 10 have at least one of them. An attachment means 31 is formed to detachably attach the first clasp portion 30a and the second clasp portion 30b. For example, a permanent magnet can be used as the fastening means.

FIG. 4 is an enlarged cross-sectional view in the longitudinal direction in which the housing portion of the magnet in the first divided body is enlarged. 5 is an enlarged cross-sectional view taken along the line DD 'in FIG.
It is desirable that the anisotropic magnets 20a and 20b accommodated in the first divided body 16A constituting the divided body 16 be rectangular so that the magnetization direction can be known. In FIGS. 3 and 4, W: H: L = 1: 2: 4.

  In addition, the length H in the height direction of the anisotropic magnets 20 a and 20 b is preferably in the range of 50% to 80% with respect to the diameter φ of the flexible string-like body 10. When H is in this range, the anisotropic magnets 20 a and 20 b can be stably supported by the concave magnet support 12, and the arrangement positions of the anisotropic magnets 20 a and 20 b are not easily shifted, and The thickness of the flexible cord-like body 10 is not too thin, and cracking or breakage of the flexible cord-like body 10 due to bending or the like does not easily occur.

  Furthermore, the corners and sides of the anisotropic magnets 20a and 20b are chamfered or rounded. As a result, for example, when the flexible string-like body 10 is excessively bent or when the pressure is excessively applied to the flexible string-like body 10, fine cracks and chips are generated in the anisotropic magnets 20a and 20b. It becomes difficult to occur.

  As materials (anisotropic magnet materials) of the anisotropic magnets 20a and 20b, those usually used as magnets for magnetic treatment tools such as rare earth magnets, anisotropic ferrite magnets, anisotropic rubber magnets are used. can do. In the present embodiment, a rare earth is used as the anisotropic magnets 20a and 20b.

  In the present embodiment, one strong magnetic force generating portion 21 is configured by two anisotropic magnets 20 a and 20 b. The strong magnetic force generation unit 21 generates a strong magnetic force capable of delivering magnetism to a distant position as compared with a single anisotropic magnet. The reason will be described with reference to FIG.

  FIG. 6A is a conceptual diagram showing the state of magnetic flux lines distributed around the anisotropic magnet 20 when the anisotropic magnet 20 is arranged alone. As represented by a broken line in FIG. 6A, when the anisotropic magnet 20 is disposed alone, the other magnets are not disposed nearby, so the periphery of the anisotropic magnet 20 is anisotropic. A magnetic flux is emitted from the N pole of the magnet 20, returns to the S pole of the same anisotropic magnet 20, and a magnetic circuit is formed in which the magnetic flux is concentrated in a region near the anisotropic magnet 20. Therefore, the magnetic flux of the anisotropic magnet 20 does not extend far from the anisotropic magnet 20.

  FIG. 6 (b) shows the state of the magnetic flux lines distributed around the anisotropic magnets 20a, 20b when two anisotropic magnets 20a, 20b with different magnetic poles facing the same side are arranged adjacent to each other. It is a conceptual diagram showing. When two anisotropic magnets 20a and 20b whose different magnetic poles are directed to the same side are disposed adjacent to each other as represented by a broken line in FIG. 6B, the N of one anisotropic magnet is obtained. Since the pole and the S pole of the other anisotropic magnet are disposed close to each other, is the magnetic flux emitted from the N pole of the anisotropic magnets 20 a and 20 b the S pole of another anisotropic magnet adjacent to it? Or return to the S pole of the same anisotropic magnet. Therefore, a magnetic circuit is formed in which the magnetic flux is concentrated in the area near the anisotropic magnets 20a and 20b. Therefore, the magnetic flux of the anisotropic magnets 20a and 20b does not extend far from the anisotropic magnets 20a and 20b.

  FIG. 6C shows the distribution of magnetic flux lines distributed around anisotropic magnets 20a and 20b when two anisotropic magnets 20a and 20b with the same magnetic pole facing the same side are arranged adjacent to each other. It is a conceptual diagram showing a state. When two anisotropic magnets 20a and 20b having the same magnetic pole facing the same side are disposed adjacent to each other as shown by the broken line in FIG. 6C, the N of one anisotropic magnet is obtained. Since the pole (or S pole) and the N pole (or S pole) of the other anisotropic magnet are disposed close to each other, the magnetic fluxes emitted from the N pole of the anisotropic magnets 20a and 20b are close to each other. The influence of the north pole of the other anisotropic magnet inhibits the passage of the region close to the anisotropic magnet to return to the south pole. Therefore, a magnetic circuit is formed in which the magnetic flux is concentrated in the area far from the anisotropic magnets 20a and 20b. Therefore, the magnetism can be delivered to a position far away from the anisotropic magnets 20a and 20b (the strong magnetic force generating portion 21).

  In the present embodiment, it is necessary to align (parallel) two anisotropic magnets 20 a and 20 b that constitute one strong magnetic force generation unit 21. At the time of magnetization, the direction in which the magnetic field is applied is constant, and if the directions of the magnet materials are not aligned, a prescribed magnetic field may not be obtained. The necessary number of second divisions 16B for adjusting the length is connected between the first divisions 16A accommodating the anisotropic magnets 20a and 20b so that the preferable distance between the strong magnetic force generation parts 21 can be maintained. do it.

(the first divided body 16A and the second divided body 16B) constituting the flexible cord-like body 10 of the magnetic therapeutic device 2 Is accommodated in the elastic tubular body 25 over the entire length of That is, the outer peripheral surface of the flexible cord-like body 10 is covered with the elastic tubular body 25 over the entire length.

  The elastic tubular body 25 is a bendable elastic body. The elastic tubular body 25 preferably has, for example, a higher elasticity than that of the flexible cord-like body 10. By making the elastic tubular body 25 highly elastic, the flexible cord-like body 10 is less likely to be deformed, so the stability of the shape is improved. Moreover, the thickness of the elastic tubular body 25 is not particularly limited, but is, for example, in the range of 0.1 mm or more and 2 mm or less.

  As a material of the elastic tubular body 25, rubber and an elastomer can be used. Examples of the rubber include silicone rubber, urethane rubber, butadiene rubber, isoprene rubber, acrylic rubber, chloroprene rubber and fluororubber. Examples of the elastomer include styrene-based elastomers, olefin-based elastomers, vinyl chloride-based elastomers, urethane-based elastomers and amide-based elastomers. In the present embodiment, silicone rubber is used.

  As described above, the flexible cord-like body 10 can be protected by accommodating the flexible cord-like body 10 including the plurality of divided bodies 16, 16 ... over the entire length in the elastic tubular body 25. In particular, the connection portion where the divided bodies 16 are connected via the connection means 17 is also covered with the elastic tubular body 25, and the joint of the connected portions of the divided bodies 16 is a series of elastic tubular bodies 25. Covering can improve the feeling of use when the magnetic treatment tool 2 comes in contact with the human body.

  For example, for the divided bodies 16, 16... Constituting the flexible cord-like body 10, a material having poor touch but excellent in strength is used, and the elastic tubular body 25 covering the flexible cord-like body 10 has strength Although not as strong as the flexible cord-like body 10, by using a material having a good touch, the magnetic therapeutic device 2 having an excellent strength and a good touch can be realized.

That is, in the flexible cord-like body 10, only the outer peripheral surface of the connection portion where the divided bodies 16 are connected via the connection means 17 is selectively covered by the elastic tubular bodies 26, 26. .

  Even in such an embodiment, the outer peripheral surface of the connection portion where the divided bodies 16 are connected via the connection means 17 is covered with the elastic tubular members 26, 26. For example, even when a tensile stress is applied in the longitudinal direction, the divided bodies 16 are prevented from being separated from one another, which contributes to the improvement of the strength of the magnetic treatment tool 2.

  Further, for example, by using colored rubber or elastomer as the elastic tubular members 26, 26 ..., the magnetic treatment tool 3 excellent in design properties which are colored intermittently (in stripes) can be realized.

"Manufacturing method of magnetic treatment tool"
Next, as an embodiment of a method of manufacturing a magnetic therapeutic device according to the present invention, a method of manufacturing the magnetic therapeutic device 1 shown in the first embodiment will be described.
12 to 14 are schematic explanatory views showing the method of manufacturing the magnetic therapeutic device of the present invention in stages.
First, as shown in FIG. 12A, using a mold T1 in which the shape of the first string-like member 11 of the first divided body 16A is engraved on the inner surface, a first string shape constituting the first divided body 16A The member 11 is molded by molding. For example, silicone rubber is used as the soft resin of the molding material.

  Next, as shown in FIG. 12B, a magnet material, for example, anisotropic magnet materials (magnet materials) 22a and 22b, is inserted into the first string-like member 11 obtained by molding. The anisotropic magnet members 22a and 22b are members that generate anisotropic magnets (magnets) 20a and 20b by magnetization. The anisotropic magnet members 22a and 22b are, for example, rectangular bodies, and corners and sides are chamfered or rounded. By this, it is possible to smoothly carry out the operation when inserting into the first string-like member 11. Such anisotropic magnet members 22 a and 22 b are inserted into the concave magnet support 12 formed in a concave shape on the surface of the first string-like member 11.

  Next, as shown in FIG. 12C, using a mold T2 in which the entire shape of the first divided body 16A is engraved on the inner surface, a first string-like member 11 in which anisotropic magnets 22a and 22b are inserted. Is placed in the mold T2, and the second string-like member 15 is joined to the surface on the side where the anisotropic magnet members 22a and 22b are inserted by insert molding. Thereby, as shown in FIG.12 (d), 1st division body constituent material 16Ap which accommodated anisotropic magnet material 22a, 22b before magnetization is obtained.

  On the other hand, as shown in FIG. 13A, the second divided body 16B is molded using a mold T3 in which the shape of the second divided body 16B is engraved on the inner surface. For example, silicone rubber is used as the soft resin of the molding material. Thereby, as shown in FIG.13 (b), the 2nd division body 16B is obtained. Such a second divided body 16B may be formed in a large amount in a batch separately from the first divided body component 16Ap.

  Next, as shown in FIG. 14A, the anisotropic magnet members 22a and 22b contained in the first divided body component 16Ap are magnetized. As a method of magnetizing the anisotropic magnet members 22a and 22b, it is possible to use a magnetized material M generally used for magnetizing magnet members. In such a magnetizing step, it is possible to magnetize a large number of first divided body components 16Ap having a short total length obtained by dividing the flexible cord-like body 10 collectively. That is, since the first divided body component 16Ap is considerably shorter than the entire length of the flexible string-like body 10, the small size and low cost can be achieved by aligning and magnetizing the first divided body component 16Ap. Even in the case of the magnetized member M, it is possible to carry out the magnetizing treatment in a large amount at once. By thus magnetizing the anisotropic magnet members 22a and 22b of the first divided body component 16Ap, it is possible to obtain a first divided body 16A accommodating anisotropic magnets 20a and 20b which are an example of a magnet. it can.

  Next, as shown in FIG. 14 (b), the desired number of anisotropic magnets 20a, 20b can be obtained by connecting the first divided body 16A and the second divided body 16B thus obtained in any combination. And the magnetic therapeutic device 1 having a desired total length can be easily manufactured.

  After that, as shown in FIG. 14 (c), the flexible string-like body 10 in which the first divided body 16A and the second divided body 16B are connected in an optional combination as required is an elastic tube-shaped body By accommodating it in 25, the magnetic treatment tool 2 shown in 2nd Embodiment can be manufactured.

  While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the invention. These embodiments can be implemented in other various forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the invention described in the claims and the equivalents thereof as well as included in the scope and the gist of the invention.

  For example, in each of the above-described embodiments, two anisotropic magnets 20a and 20b are disposed adjacent to each other such that the same magnetic pole faces the same side, and two anisotropic magnets 20a and 20b Although the two strong magnetic force generating portions 21 are configured, the present invention is not limited to this case. Specifically, a plurality of anisotropic magnets may be arranged at mutually separated positions so that the magnetism generated by each anisotropic magnet may act on the human body.

  Moreover, in each embodiment mentioned above, although anisotropic magnet 20a, 20b is made into a rectangular parallelepiped, it is not limited to this. Specifically, the anisotropic magnets 20a and 20b can be formed in a columnar shape such as a cylindrical shape, an elliptic cylindrical shape, or a polygonal cylindrical shape. Furthermore, although the above-mentioned embodiment demonstrated the example which used the anisotropic magnet as a magnet, you may use an isotropic magnet and another magnet.

  Moreover, in each embodiment mentioned above, although the convex part 13 of the 1st string-like member 11 is made into trapezoid shape whose upper base is shorter than the lower part, it is not limited to this. Specifically, the convex portion can be semicircular or semielliptical.

  Further, in order to increase the frictional resistance between the flexible cord-like body 10 and the elastic tubular body 25 to make it difficult for the elastic tubular body 25 to be detached from the flexible cord-like body 10, The inner circumferential surface or a part or all of the surface of the flexible cord 10 may be knurled.
