  The opposite side of the coupling surface 11a and the opposite side of the coupling surface 12a are formed so as to be magnetized to S polarity from one end to the other end in the longitudinal direction. However, the present invention is not limited thereto, and the coupling surface 11a side and the opposite side of the coupling surface 12a may be formed so that different magnetic poles are arranged. For example, the north and south poles may be alternately magnetized on the opposite side of the coupling surface 11a at regular intervals.

  Further, when the first string-like member 11 and the second string-like member 12 are coupled by a mold, the convex fastener 13A and the concave fastener 13B may be attached together.

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. In this embodiment, the first string-like member 61 is a solid body having a string-like shape extending in the longitudinal direction, and is formed in a substantially semicircular shape when viewed in cross section. The first string member 61 is formed with a coupling surface 61 a that couples with the coupling surface 62 a of the second string member 62. Further, the first string-like member 61 is formed with a non-bonding surface 61 b that becomes the outer peripheral surface of the main body 10. The coupling surface 61a corresponds to a straight portion that is semicircular in sectional view, and is formed as a plane that extends parallel to the longitudinal direction of the first string-like member 61. The non-bonding surface 61 b corresponds to a circumferential portion that is semicircular in sectional view, and is formed as a semi-cylindrical surface that extends in the longitudinal direction of the first string-like member 61.

  In the present embodiment, on the coupling surface 61a side, a first N pole portion that is magnetized to N polarity as a whole is formed from one end portion in the longitudinal direction to the other end portion. Further, on the opposite side of the coupling surface 61a, a first S pole portion is formed which is magnetized to S polarity as a whole from one end portion in the longitudinal direction to the other end portion.

  As shown in FIG. 10, in the present embodiment, the second string-like member 62 is a solid body extending in the longitudinal direction in a string shape, and is formed in a substantially semicircular shape when viewed in cross section. Yes. The second string-like member 62 is formed with a coupling surface 62 a that couples with the coupling surface 61 a of the first string-like member 61. Further, the second string-like member 62 is formed with a non-bonding surface 62 b that becomes the outer peripheral surface of the main body 10. The coupling surface 62a corresponds to a straight portion that is semicircular in sectional view, and is formed as a plane that extends parallel to the longitudinal direction of the second string-like member 62. The non-bonding surface 62 b corresponds to a circumferential portion that is semicircular in sectional view, and is formed as a semicylindrical surface that extends in the longitudinal direction of the second string-like member 62.

  In the present embodiment, on the coupling surface 62a side, a second S pole portion is formed which is magnetized to S polarity as a whole from one end portion in the longitudinal direction to the other end portion.

  In the present embodiment, the coupling surface 61a side and the coupling surface 62a side have different polarities, N polarity and S polarity. For this reason, the coupling surface 61a of the first string-shaped member 61 and the coupling surface 61a of the second string-shaped member 62 are easier to combine than when coupling surfaces having different polarities are combined. Moreover, a magnetic field different from the case where the coupling surfaces having the same polarity are coupled to each other is formed.

[Other embodiment 2]
FIG. 11 is a cross-sectional view before joining the first string-like member and the second string-like member, showing another embodiment 2 of the decorative article of the present invention. FIG. 12 is a cross-sectional view after the first string-like member and the second string-like member are joined, representing another embodiment 2 of the decorative article of the present invention. Another embodiment 2 will be described with reference to FIG. In the other embodiment 2, the same reference numerals are given to the same parts as those in the above-described embodiment, and the detailed description is omitted. In this embodiment, the first string-like member 71 is a solid body having a string-like shape extending in the longitudinal direction, and is formed in a substantially semicircular shape when viewed in cross section. The first string member 71 is formed with a coupling surface 71 a that couples with the coupling surface 72 a of the second string member 72. Further, the first string-like member 71 is formed with a non-bonding surface 71 b that becomes the outer peripheral surface of the main body 10. The coupling surface 71a corresponds to a straight portion that is semicircular in cross-sectional view, and is formed as a plane that extends parallel to the longitudinal direction of the first string-like member 71. The non-bonding surface 71 b corresponds to a semicircular outer peripheral portion in cross section and is formed as a semi-cylindrical surface extending in the longitudinal direction of the first string-like member 71.

  The coupling surface 71a is in a portion corresponding to the approximate center of the straight portion of the first string-like member 71 in a semicircular cross-sectional view, and forms a groove 71c. The dovetail groove 71 c is formed from one end in the longitudinal direction of the first string-like member 71 to the other end. The dovetail portion 71c formed in the coupling surface 71a has an opening 71e formed on the coupling surface 71a side, and a bottom 71d formed at a predetermined depth from the coupling surface 71a side. The dovetail groove 71c is formed such that the width of the bottom 71d is wider than the width of the opening 71e in a sectional view.

  In the present embodiment, on the coupling surface 71a side, a first N pole portion that is magnetized to N polarity as a whole is formed from one end portion in the longitudinal direction to the other end portion. Further, on the opposite side of the coupling surface 71a, a first S pole portion is formed which is magnetized to the S polarity as a whole from one end portion in the longitudinal direction to the other end portion.

  As shown in FIG. 11, in the present embodiment, the second string-like member 72 is a solid body having a string-like shape extending in the longitudinal direction, and is formed in a substantially semicircular shape when viewed in cross section. Yes. The second string-like member 72 is formed with a coupling surface 72 a that couples with the coupling surface 71 a of the first string-like member 71. Further, the second string-like member 72 is formed with a non-bonding surface 72b that becomes the outer peripheral surface of the main body portion 10. The coupling surface 72 a corresponds to a straight portion that is semicircular in sectional view, and is formed as a plane that extends parallel to the longitudinal direction of the second string-like member 72. The non-bonding surface 72 b corresponds to an outer peripheral portion that is semicircular in sectional view, and is formed as a semi-cylindrical surface that extends in the longitudinal direction of the second string-like member 72.

  The coupling surface 72a is in a portion corresponding to substantially the center of the straight portion of the second string-like member 72 that is semicircular in cross section, and integrally forms a portion 72c. The presence portion 72 c is formed from one end portion in the longitudinal direction of the second string-like member 72 to the other end portion. The dovetail portion 72c in the present embodiment is a trapezoidal projection protruding from the coupling surface 72a that engages the dovetail groove portion 71c in a system-detachable manner. The section 72c is formed so that the width of the base portion 72e on the coupling surface 72a side is wider than the width of the protruding upper surface portion 72d in a cross-sectional view.

  In the present embodiment, on the coupling surface 72a side, a second N pole portion that is magnetized to N polarity as a whole is formed from one end portion in the longitudinal direction to the other end portion. Further, on the opposite side of the coupling surface 72a, a second S pole portion is formed which is magnetized to the S polarity as a whole from one end portion in the longitudinal direction to the other end portion.

  The opening 71e and the root 72e are formed with substantially the same width in cross-sectional view. The bottom portion 71d and the upper surface portion 72d are formed with substantially the same width when viewed in cross section. Since the dovetail part 71c and the dove part 72c are formed of soft silicone resin, they can be easily inserted. That is, as shown in FIG. 12, when the portion 72c is pushed toward the portion 71c, the opening 71e and the upper surface 72d are elastically deformed and fitted. And in the state where it fitted, it couple | bonds in what is called a dovetail shape and is mutually hold | maintained by the frictional force and the elastic force.

  In the present embodiment, the coupling surface 71a side and the coupling surface 72a side have N polarity which is the same polarity. For this reason, the coupling surface 71a of the first string-like member 71 and the coupling surface 71a of the second string-like member 72 are harder to be coupled than when coupling surfaces having different polarities are coupled to each other. For this reason, the 1st string-like member 71 and the 2nd string-like member 72 can be couple | bonded against the polarity which repels by previously fitting the dovetail part 71c with the dovetail groove part 71c. Needless to say, an adhesive may be applied to the coupling surface 71a and the dovetail portion 71c and / or the coupling surface 72a and the dosing portion 72c for bonding.

[Other embodiment 3]
FIG. 13 is an external view showing a connected necklace 201 to which another embodiment 3 of the decorative article of the present invention is applied. FIG. 14 is a front view showing the necklace 201 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. In this embodiment, the main body 210 has a direction around the center of the main body 210 after the coupling surface 211a of the first string member 211 and the coupling surface 212a of the second string member 212 overlap in parallel in the longitudinal direction. It is formed by being twisted. The main body 210 may be twisted once or multiple times.

  The necklace 201 in the present embodiment is preferably manufactured by the following method. For example, the first string-like member 211 and the second string-like member 212 are integrated by the manufacturing method to constitute the main body 210. Next, one end portion in the longitudinal direction of the main body portion 210 and the other end portion are appropriately twisted in the direction around the center of the main body portion 210. Next, the twisted main body 210 is again pressed against the groove 31 of the lower mold 30 and installed. Next, positioning is performed by a positioning member including a positioning pin and a positioning hole, and the mold is closed. In this state, the heating press devices 40 and 50 provided outside the upper mold 20 and the lower mold 30 are heated and further pressurized. After the shape is determined with the main body 210 being twisted in the mold, the upper mold 20 and the lower mold 30 are separated and opened. The main body 210 that is solidified and molded from the mold is taken out. A convex fastener 13A and a concave fastener 13B are attached to both ends of the main body 210 to complete. Needless to say, the main body 210 may be twisted rightward or leftward around the center of the main body 210.

  Since the main body 210 is formed by being twisted, the direction of the magnetic field becomes complicated, and a more effective health promotion effect can be expected. Further, the main body 210 is formed by being twisted, so that the colors are intertwined and the design is improved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. Needless to say, changes can be made without departing from the scope of the present invention. For example, the cross-sectional shape of the main body may be an elliptical shape, an oval shape, a polygonal shape, or the like.
