More particularly, the present invention relates to a decorative article that is friendly to a wearer and has a health direction improving effect by complicating the direction of a magnetic field, and a method of manufacturing the decorative article.

  Conventionally, magnetic necklaces and magnetic bracelets have been used as magnetic treatment tools for the purpose of health promotion by magnetic force. That is, it is said that stiff shoulders and muscle pain are alleviated by the magnetic force promoting blood circulation, and many people love magnetic necklaces.

Various proposals have been made as patent documents. For example, as a magnetic therapy device, there are a metal magnet or a magnet encased in a capsule connected with a chain or a metal ring, or a magnetized body knitted into a net (see, for example, Patent Document 1). In addition, a magnetic treatment device using a rubber magnet or the like as a material is also known (see, for example, Patent Document 2). Also known is a health device or the like in which a plurality of sets each consisting of a plurality of permanent magnets and a plurality of negative ion generators are alternately housed in a flexible tube and the ends of the tube are sealed ( For example, see Patent Document 3). Moreover, there exists what puts a jewelry in the middle of making an annular bracelet with transparent silicone rubber (for example, refer patent document 4). Furthermore, silicon rubber and other rubber-based materials that are extruded in a press molding machine together with the above-mentioned mold by placing a plurality of different-colored kneaded pieces in a ring mold provided in the extrusion mold.

  However, the technique disclosed in Patent Document 1 has a risk of damaging the body during exercise or the like because metal or the like is exposed. Since the technique disclosed in Patent Document 2 is composed of a single rubber magnet, the direction of the magnetic field (or lines of magnetic force) emitted from the magnetic therapy device is monotonous and has a limited impact on promoting physical health. There was a risk of becoming. The technique disclosed in Patent Document 3 is only fragile because it only includes a permanent magnet or the like in the tube and is not an integral configuration. Therefore, there is a demand for the development of a further improved health promotion effect.

  On the other hand, for ornamental items such as necklaces and bracelets, those with jewels, those made of precious metals, and those with excellent decorative properties are preferred. Necklaces and bracelets for promoting health are also preferred because of their decorativeness. Such necklaces and bracelets do not have to be provided with very expensive jewels or the like, and are preferably those having a good design aesthetic sense or designs that the user likes. Also, such necklaces and bracelets should be reasonably priced rather than too expensive.

  However, the technique described in Patent Document 4 is expensive and cannot be expected to have a health promotion effect because jewels are contained in silicon rubber. The technique described in Patent Document 5 is only capable of coloring the designated portion of the product, and the decoration provided in the product cannot be arranged at a predetermined position, so the design is poor. The health promotion effect could not be expected. Therefore, there is a demand for the development of a product that has an improved design and aesthetic sense and has improved health promotion effects.

  Furthermore, since necklaces and bracelets are always in direct contact with the skin, some metallic ones have developed metal allergies, and the materials and the like have to be very careful. Also, since it is attached to the body every day, it can hardly feel uncomfortable and heavy when worn, and it can prevent scratches even when worn on the body for a long time. Is required.

  The main body 10 is formed to have a predetermined length (for example, 400 to 600 mm) in the longitudinal direction. This length is appropriately determined depending on the body part to be decorated, the number of windings, and the like. The main body 10 is formed in a substantially circular diameter (for example, 3 to 8 mm) when viewed in a cross-section (hereinafter simply referred to as “cross-sectional view”) on a plane orthogonal to the longitudinal direction.

In this Embodiment, the ceiling part 31a of the groove | channel 31 is magnetized by S polarity over the longitudinal direction.

  The string-like member 11 is elastically deformable, and may be installed against the pushing elastic force so as to be pressed into the groove 21. In this state, the string-like member 11 is positioned and held by the lower mold 20 and therefore cannot be removed even if left standing.

  A pair of molds constituted by the lower mold 20 and the upper mold 30 is magnetized at least partially to one polarity in the longitudinal direction. Then, with reference to the string-like member 11 set in the pair of molds, another part which is a symmetric position from the position magnetized to one polarity is magnetized to another polarity.

  In the present embodiment, the lower mold 20 is magnetized in N polarity with the bottom 21a of the groove 21 extending in the longitudinal direction. Further, the upper mold 30 is magnetized to S polarity with the ceiling portion 31a of the groove 31 extending in the longitudinal direction. That is, the bottom portion 21a and the ceiling portion 31a are formed so as to be symmetrical with respect to the string-like member 11 when the lower mold 20 and the lower mold 30 are closed, and are magnetized to different polarities. However, it is needless to say that the other portions of the groove 21 and the groove 31 may be magnetized without being limited to this configuration.

<Inserting the magnet piece into the recess (S108)>
As shown in FIGS. 8 and 9, the magnet piece 12 is inserted into the recess 11 h provided in the string-like member 11. In the present embodiment, the entire magnetic pole surface 12a side of the magnet piece 12 is magnetized to N polarity. Further, the entire magnetic pole surface 12b side is magnetized to S polarity. The lower mold 20 is magnetized to N polarity with the bottom 21a of the groove 21 in the longitudinal direction. Thus, the magnetic pole surface 12b side is configured with a polarity different from that of the lower mold 20 and attracts each other, so that the magnetic pole surface 12b side is installed so as to face the lower mold 20 side through the string-like member 11. Thus, the magnet piece 12 provided inside the string-like member 11 can be positioned in a direction corresponding to the polarity of the mold by magnetizing an arbitrary part of the mold to a certain polarity. it can.

<Filled with silicone resin (S109)>
As shown in FIG. 11, a filler 11 f is filled into a recess 11 h provided in the string-like member 11. In the present embodiment, as the filler 11f, the same silicone resin as that of the string-like member 11 is heated and softened. However, the present invention is not limited to this, and the same material as the string-like member 11 may be used. In the present embodiment, a description is given of a step of filling the filler 11f after putting the magnet piece 12 into the recess 11h. However, the present invention is not limited to this step, and it is needless to say that the magnet piece 12 may be put in the filler 11f after filling the recess 11h with the filler 11f.

  The filler 11f may be the same as or similar to the string-like member 11, and may be filled in the dent 11h while being softened by heating. The magnet piece 12 can move freely in the recess 11h because the filler 11f is softened. However, the magnet piece 12 is affected by the N polarity of the lower mold 20, and the S-polarity magnetic pole surface 12b side, which is a different polarity from that, is on the lower side. Positioned to face the mold 20 side. That is, the orientation of the magnet segment 12 in the recess 11 h is determined by the polarity of the magnet segment 12 itself and the polarity of the lower mold 20.

  In the present embodiment, the lower mold 20 is magnetized in N polarity with the bottom 21a of the groove 21 extending in the longitudinal direction, but it is needless to say that the present invention is not limited to this. That is, it goes without saying that the polarity of the groove 21 may be the S polarity, and portions other than the bottom 21a may be magnetized. For example, it goes without saying that the opening right side portion 21b or the opening left side portion 21c of the groove 21 may be magnetized to N polarity or S polarity. Thus, the magnet piece 12 provided inside the string-like member 11 can be positioned in a direction corresponding to the polarity of the mold by magnetizing an arbitrary part of the mold to a certain polarity. it can.

<Assembly (S110)>
Next, positioning is performed by a positioning member including a positioning pin and a positioning hole, and the mold is closed. That is, they are assembled to the lower mold 20 and the upper mold 30 having the same configuration after being aligned.

  It should be noted that after assembling the lower mold 20 and the upper mold 30, it is preferable to allow a certain time in the assembled state before heating and pressurization described later. The magnet piece 12 can move freely in the recess 11h because the filler 11f is softened. However, the magnet piece 12 is influenced by the S polarity of the upper mold 30, and the N-polar magnetic pole surface 12a side, which has a different polarity, is on the upper side. Positioned to face the mold 30 side. That is, the orientation of the magnet segment 12 in the recess 11 h is determined by the polarity of the magnet segment 12 itself and the polarity of the upper mold 30.

  In this way, the magnet piece 12 provided inside the string-like member 11 is magnetized to a certain polarity in any part of the upper mold 30 and the lower mold 20, thereby allowing the upper mold 30 and the lower mold 30 to be magnetized. The mold 20 can be positioned in a direction corresponding to the polarity. Further, since the polarity of the magnetic pole surface 12a of the magnet piece 12 is different from that of the magnetic pole surface 12b located on the opposite side and the polarity of the upper die 30 and the lower die 20 is different, the orientation of the magnet piece 12 is more stable. Positioning is possible with. That is, the N polarity of the magnetic pole surface 12a and the S polarity of the upper mold 30 are attracted, and the S polarity of the magnetic pole surface 12b and the N polarity of the lower mold 20 are attracted, so that the magnet piece 12 is stabilized in the string-like member 11. Positioning is possible in the state.

<Heating and pressurizing (S111)>
In this state, when the heating presses 40 and 50 provided outside the lower mold 20 and the upper mold 30 are heated and further pressurized, the lower mold 20 and the upper mold 30 are pressed. The heating temperature at this time is preferably a predetermined temperature (for example, 180 ° C.). The applied pressure may be a predetermined pressure. The string-like member 11, the magnet piece 12, and the filler 11 f are integrated by this heating and pressure to constitute the main body 10.

<Mold separation (S112)>
After the string-like member 11, the magnet piece 12, and the filler 11f are integrated in the mold to form the main body, the lower mold 20 and the upper mold 30 are separated and opened.

<Removal (S113)>
The main body 10 formed by solidification from the mold is taken out. At this time, if extra burrs or the like have occurred, the burrs should be removed.
<Attaching the fastener (S114)>
A convex fastener 13A and a concave fastener 13B are attached to both ends of the main body 10 to complete.

  As described above, in the present embodiment, the string-like member 11 has been described on the assumption that it is made of a silicone resin, but it may be made of a silicone resin and a ferrite magnet. At this time, the string-like member 11 and the magnet piece 12 may be configured such that the blending ratio of the silicone resin and the ferrite magnet is different.

  Furthermore, in the present embodiment, the magnetic pole surface 12a side is magnetized to N polarity, and the magnetic pole surface 12b side is magnetized to S polarity. However, the present invention is not limited thereto, and the magnetic pole surface 12a side and the magnetic pole surface 12b side may be formed so that different magnetic poles are arranged. For example, the N pole and the S pole may be alternately magnetized on the magnetic pole surface 12a side at regular intervals.

  Furthermore, in the present embodiment, the bottom portion 21a of the lower mold 20 is magnetized to N polarity, and the ceiling portion 31a of the upper mold 30 is formed to be magnetized to S polarity. However, the present invention is not limited to this, and the bottom 21a of the lower mold 20 may be magnetized to S polarity, and the ceiling 31a of the upper mold 30 may be magnetized to N polarity. Further, the N pole and the S pole may be alternately magnetized continuously at a constant interval in the longitudinal direction of the bottom portion 21a, and the N pole and the S pole are alternately continued at a constant interval in the longitudinal direction of the ceiling portion 31a. Needless to say, it may be magnetized.

  Further, when the string-like member 11, the magnet piece 12, and the filler 11f are coupled by a mold, the convex fastener 13A and the concave fastener 13B may be attached together. In this case, it goes without saying that the shape of the grooves provided in the lower mold 20 and the upper mold 30 may be formed in accordance with the shapes of the string-like member 11, the convex fastener 13A, and the concave fastener 13B. Absent.

  Alternatively, the recess 11h provided in the string-like member 11 and the magnet piece 12 may be substantially the same in size so as to be fitted. Furthermore, after putting it in a silicone resin or the like, the magnet piece 12 may be positioned by providing a thin film by drying the surface. Further, the recess 11 h may be provided at an arbitrary position in the circumferential direction of the string-like member 11.

However, it is needless to say that the other portions of the groove 121 and the groove 131 may be magnetized without being limited to this configuration.

  Before assembling the lower mold 120 and the upper mold 130 and passing through the heating and pressurizing steps, it is preferable to leave a certain time in the assembled state. This is because the positions of the respective magnet segments 12 are aligned with time. The magnet piece 12 can be freely moved in the recess 11h because the filler 11f is softened, but is positioned by being influenced by the S polarity of the opening left side portions 121c and 131c and the N polarity of the opening right side portions 121b and 131b. . That is, the magnet piece 12 is positioned so that the N-polarity magnetic pole surface 12a side faces the opening left side portions 121c and 131c having different polarities. The magnet piece 12 is positioned so that the S-polarity magnetic pole surface 12b side faces the opening right side parts 121b and 131b having different polarities. That is, the orientation of the magnet segment 12 in the recess 11h is determined by the polarity of the magnet segment 12 itself and the polarity of the lower mold 120 and the upper mold 130.

  As described above, the magnet piece 12 provided inside the string-like member 11 is magnetized in an arbitrary portion of the upper mold 130 and the lower mold 120 with a certain polarity, so that the upper mold 130 and the lower mold 130 are magnetized.

Another embodiment will be described with reference to FIG. In other embodiments, the same reference numerals are given to the same portions as those in the above-described embodiment, and detailed description thereof is omitted.

  The lower mold 220 is plate-shaped, and a groove 221 for installing the string member 11 is provided on the surface of the lower mold 220. The groove 221 is a long and narrow recess formed in the lower mold 220 so that the longitudinal half of the string-like member 11 can be installed. The width of the groove 221 is preferably slightly smaller than the width of the string-like member 11. The groove 221 has a substantially semicircular shape in cross-sectional view, and has substantially the same shape as half of the string-like member 11 in cross-sectional view. The groove 221 includes a bottom portion 221a that becomes a bottom when the string-like member 11 is installed, and an opening right side portion 221b and an opening left-side portion 221c that hold both ends of the string-like member 11 when the string-like member 11 is installed. In the present embodiment, the inclined portion 221t provided at a position of approximately 45 degrees between the opening left side portion 221c and the bottom portion 221a of the groove 221 is magnetized to S polarity in the longitudinal direction.

The groove 231 includes a ceiling portion 231a that becomes a ceiling when the string-like member 11 is installed, and an opening right side portion 231b and an opening left-side portion 231c that suppress both ends when the string-like member 11 is installed. In the present embodiment, the oblique portion 231t provided at a position of approximately 45 degrees between the opening right side portion 231b of the groove 231 and the ceiling portion 231a is magnetized to N polarity in the longitudinal direction.

  A pair of molds constituted by the lower mold 220 and the upper mold 230 is magnetized at least partially in one polarity in the longitudinal direction. Then, with reference to the string-like member 11 set in the pair of molds, another part which is a symmetric position from the position magnetized to one polarity is magnetized to another polarity.

  In the present embodiment, the lower mold 220 is magnetized to the S polarity with the oblique portion 221t of the groove 221 extending in the longitudinal direction. Further, the upper mold 230 is magnetized to N polarity over the oblique portion 231t of the groove 231 in the longitudinal direction. That is, the slant portion 221t and the slant portion 231t are formed so as to be symmetrical with respect to the string-like member 11 and have different polarities when the lower mold 220 and the upper mold 230 are closed. However, the present invention is not limited to this configuration, and it goes without saying that other portions of the groove 221 and the groove 231 may be magnetized.

  Before assembling the lower mold 220 and the upper mold 230 and performing the heating and pressurizing steps, it is preferable to allow a certain time in the assembled state. This is because the positions of the respective magnet segments 12 are aligned with time. The magnet piece 12 can be freely moved in the recess 11h because the filler 11f is softened, but is positioned by being influenced by the S polarity of the oblique portion 221t and the N polarity of the oblique portion 231t. That is, the magnet piece 12 is positioned so that the N-polar magnetic pole surface 12a side faces the oblique portion 221t side having a different polarity. The magnet piece 12 is positioned so that the S-polarity magnetic pole surface 12b side faces the oblique portion 231t side having a different polarity. That is, the orientation of the magnet segment 12 in the recess 11h is determined by the polarity of the magnet segment 12 itself and the polarity of the lower mold 220 and the upper mold 230.

  As described above, the magnet piece 12 provided inside the string-like member 11 is magnetized in an arbitrary part of the upper mold 230 and the lower mold 220 with a certain polarity, so that the upper mold 230 and the lower mold 230 are magnetized. The mold 220 can be positioned in a direction corresponding to the polarity. Further, the polarity of the magnetic pole surface 12a of the magnet piece 12 and the polarity of the magnetic pole surface 12b located on the opposite side are different, and the polarity of the oblique portion 221t and the opening oblique portion 231t are different. Positioning is possible. That is, the N polarity of the magnetic pole surface 12a and the S polarity of the oblique portion 221t attract each other, and the S polarity of the magnetic pole surface 12b and the N polarity of the oblique portion 231t attract each other, so that the magnet piece 12 is stable in the string-like member 11. Positioning is possible.

  Furthermore, in the present embodiment, the oblique portion 221t provided at a position of approximately 45 degrees between the opening left side 221c and the bottom 221a of the groove 221 is magnetized to the S polarity in the longitudinal direction. Further, the oblique portion 231t provided at a position of approximately 45 degrees between the opening right side portion 231b of the groove 231 and the ceiling portion 231a is magnetized to N polarity in the longitudinal direction. However, the present invention is not limited to this, and a position of approximately 45 degrees between the opening right side 221b and the bottom 221a of the groove 221 may be magnetized to the S polarity in the longitudinal direction. Further, the position of approximately 45 degrees between the opening left side 231c of the groove 231 and the ceiling 231a may be magnetized to N polarity over the longitudinal direction. Needless to say, the magnet segment 12 may be positioned by limiting the angle at which the mold is magnetized to 45 degrees, but not by any other angle.

[Other embodiment 3]
FIG. 14 is an external view showing a connected necklace 301 to which another embodiment 3 of the decorative article of the present invention is applied. FIG. 15 is a front view of the necklace 301 in an unconnected state. Another embodiment 3 will be described with reference to FIG. In other embodiment 3, the same code | symbol is provided to the site | part same as embodiment mentioned above, and detailed description is abbreviate | omitted.

  The string-like member 311 is provided with one or a plurality of magnet segments 312 at a predetermined interval in the axial direction inside the string-like member 311. In the present embodiment, the magnet piece 312 is configured by an elliptical column shape including two magnetic pole surfaces 312a and 312b formed in an elliptical shape and side surfaces formed in a substantially cylindrical shape.

  The long sides constituting the magnetic pole surfaces 312a and 312b are preferably shorter than the length of the circular diameter of the main body 310 viewed in cross section. The height of the cylindrical shape that is the side surface connecting the two magnetic pole surfaces 312a and 312b is preferably shorter than the length of the circular diameter of the main body portion 310 as viewed in cross section. In the present embodiment, the magnet section 312 is described as having a substantially elliptical column shape, but it is needless to say that the magnet piece 312 may be configured in other forms. For example, it goes without saying that it may be a cylinder.

  The magnet piece 312 is made of a soft silicone resin. In the present embodiment, the magnet piece 312 is described as being formed of a silicone resin, but a soft elastically deformable material, for example, a soft synthetic resin such as a soft urethane resin, or an elastomer Etc. may be formed.

  A magnet is kneaded and dispersed in the magnet piece 312. The magnet is a magnet that is finely powdered, for example, a ferrite magnet that is powdered. In the present embodiment, a ferrite magnet is described. However, other types of magnets (for example, alnico magnets and neodymium magnets) may be used as long as they are magnets.

  Further, the ferrite magnet and the silicone resin in the magnet segment 312 are mixed at a predetermined mixing ratio (for example, ferrite magnet is 80 to 95 mass%, silicone resin is 5 to 20 mass%). This mixing ratio may be changed within a range where the surface magnetic flux density does not exceed 0.2 Tesla (2000 Gauss).

  In the present embodiment, one or a plurality of magnet segments 312 are provided so as to face each other in the direction of the outer peripheral surface side of the string-like member 11 at predetermined intervals. That is, as shown in FIG. 14, the magnetic pole surfaces 312 a of the plurality of magnet segments 312 are provided so as to face each of the outer peripheral surface sides of the separate string-like members 11. Each is provided separately to face the direction of the outer peripheral surface of the string-like member 11. The entire magnetic pole surface 312a is magnetized to N polarity, and the entire magnetic pole surface 312b located on the opposite side of the magnetic pole surface 312a is magnetized to S polarity.

  In the present embodiment, the magnet piece 312 is magnetized by dispersing the ferrite magnets. For example, the magnet piece 312 kneads a magnetized ferrite magnet into a silicone resin or the like that is a material of the magnet piece 312. Next, a long plate-like body is formed by extrusion molding or the like with an extrusion molding machine or the like. Next, the ferrite magnet particles are magnetized by arranging them in one direction by a method such as mechanical orientation in which a mechanical pressure is applied to the long plate-like body or molding in a magnetic field that is oriented using a magnetic field coil. Finally, the magnet piece 312 may be formed by cutting a magnetized long plate-like body into an appropriate elliptical size.

  The magnet piece 312 kneads unmagnetized ferrite into a silicone resin or the like that is a material of the magnet piece 312. Next, a magnetic field coil is arranged around the mold, or it is magnetized by magnetizing it while forming a long plate-like body by extrusion molding with an extrusion molding machine etc. that magnetizes the mold itself. Let Finally, the magnet piece 312 may be formed by cutting a magnetized long plate-like body into an appropriate size.

  In the present embodiment, the string-like member 311 constituting the main body portion 310 is a solid body having a string-like shape extending in the longitudinal direction, and is formed in a substantially circular shape in cross section. One or more magnet segments 312 are provided at predetermined intervals in the axial direction inside the string-like member 311. The magnet piece 312 is made of a thermoplastic resin such as silicone resin, and is integrally coupled to the string-like member 311 by heating and pressurizing it. As described above, the main body 310 configured by combining the string-like member 311 and the magnet piece 312 has a complicated magnetic field direction, and can be expected to have a health promoting effect. Needless to say, an adhesive may be applied to the surfaces of the magnetic pole surfaces 312a and 312b to be coupled to the main body 310.

  As shown in FIG. 15, in the present embodiment, the entire magnetic pole surface 312a side is magnetized to N polarity. Further, the entire magnetic pole surface 312b side is magnetized to S polarity. That is, the magnetic pole surface 312a constituting one surface of the magnet piece 312 and the magnetic pole surface 312b constituting another surface located on the opposite side are magnetized with different polarities.

  In the present embodiment, one or a plurality of magnet pieces 312 are provided separately in the direction of the outer peripheral surface side of the string-like member 11. That is, the magnetic pole surfaces 312a and the magnet surfaces 312b of the plurality of magnet segments 312 are provided separately in the direction of the outer peripheral surface side of the string-like member 11, and thus the formed magnetic field is different from each magnetic pole. It is formed according to the orientation of the surfaces 312a and 312b. In this way, by configuring each of the magnet segments 312 to face in various directions, it is possible to improve the degree of influence exerted on the body by forming a magnetic field in various directions and further improve health.

  In order to separately direct the magnet pieces 312 in the direction of the outer peripheral surface side of the string-like member 11, at least a part of the pair of molds constituted by the lower mold and the upper mold is at least one of the longitudinal directions. It should be magnetized to polarity. In the present embodiment, the pair of molds includes a part magnetized to one polarity on the basis of one magnet segment 312 placed in a string-like member set in the pair of molds, A positioning magnet is provided in which the other part magnetized to the other polarity and the other part magnetized to the other polarity.

  In the present embodiment, the necklace 301 is formed of a mold in which a plurality of positioning magnets configured from one polarity and the other polarity are provided at regular intervals in the longitudinal direction of a pair of molds. Further, the plurality of positioning magnets provided in the mold do not need to be aligned in a certain direction, and are provided in all directions so that the magnet segments 312 are directed in various directions. By providing the positioning magnet in this manner, the magnet piece 312 is configured to face in various directions.
