Description

  The present invention relates to a decorative article having a function of imparting a health promotion effect to the body by magnetism and a method for manufacturing the decorative article. 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, a magnetic treatment device that suppresses the occurrence of metal allergy and has a highly durable magnetic accessory or a homeostasis maintenance function and a health promotion function is known (for example, see Patent Document 1). In addition, there are known magnetic treatment accessories such as pendants, necklaces, bracelets and the like that can be expected to have a therapeutic effect due to magnetic force while having a beautiful appearance and pattern and satisfying visual taste (for example, Patent Document 2).

  However, the technique disclosed in Patent Document 1 is merely a material in which a ferrite-based magnet is added in a silicon rubber magnet, and is composed of a single rubber magnet. The direction of the magnetic field (or lines of magnetic force) is monotonous, which may have a limited impact on promoting physical health.

  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 a necklace or bracelet does not have to be provided with a very expensive jewel, and it is preferable that the necklace or the bracelet has a design with an excellent aesthetic sense or a design that the user likes. Also, such necklaces and bracelets should be reasonably priced rather than too expensive.

  However, the technique described in Patent Document 2 is expensive, because jewelry is contained in the synthetic resin, and is expensive and complicated in structure and manufacturing process, so that the manufacturing cost per unit price is high. .

  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.

In this state, the second string-like outer layer member or the first string-like outer layer member is positioned and held in the lower mold, and therefore cannot be removed even if left unattended.

  An adhesive may be applied before bonding the first string-like outer layer member or the second string-like outer layer member. That is, an adhesive may be applied to the coupling surface of the first string-like outer layer member installed in the upper mold and / or the coupling surface of the second string-like outer layer member installed in the lower mold. The adhesive may be, for example, a silicone resin adhesive having the same quality as that of the first string-like outer layer member or the second string-like outer layer member, but it goes without saying that other adhesives such as an epoxy-based adhesive may be used.

<String-like core member, string-like magnet member set (S110)>
The string-like magnet member 14a provided along the outer circumferential surface of the string-shaped core member 12 and the string-shaped core member 12 in the recess provided in the longitudinal center of the first string-shaped outer layer member and the second string-shaped outer layer member. , 14b, 14c are set.

<Assembly (S111)>
Next, positioning is performed by a positioning member including a positioning pin and a positioning hole, and the mold is closed. In other words, the upper and lower molds having the same configuration are aligned and assembled.

<Heating and pressurizing (S112)>
In this state, when the heating press apparatus provided outside the upper mold and the lower mold is heated and further pressurized, the upper mold and the lower mold 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. With this heating and pressure, the first string-like outer layer member and the second string-like outer layer member are integrated to form the string-like outer layer member 11.

<Mold separation (113)>
After the first string-shaped outer layer member and the second string-shaped outer layer member are integrated in the mold to form the string-shaped outer layer member 11, the upper mold and the lower mold are separated and opened.

However, it is not limited to this configuration. For example, the string-like magnet member 114 may be wound at various intervals on the circumference of the outer peripheral surface of the string-like core member 112 without being arranged at equal intervals in the axial direction. Further, the number of string-like magnet members is not limited to one, and a plurality of string-like magnet members may be provided. Even if they are wound on the outer peripheral surface of the string-like core member 112 at equal intervals in the axial direction, they are wound at an appropriate interval. May be. Further, when a plurality of string-like magnet portions are provided, the string-like magnet members may be formed to have different polarities. In the present embodiment, the string-like outer layer member 111 is described as being transparent. However, the present invention is not limited to this, and the string-like core member 112 and the string-like magnet member 114 may be transparent. It goes without saying that it is good.

In the main body 110, lines of magnetic force are generated at various positions from locations where the string-like magnet members 214a, 214b, and 214c are provided. For example, when the string-like magnet members 214a and 214c are magnetized to the S polarity and the string-like magnet member 214b is magnetized to the N polarity, lines of magnetic force are generated from the string-like magnet member 214b to the string-like magnet members 214a and 214c. The magnetizations of the string-like magnet members 214a, 214b, and 214c are not limited to this, and other combinations may be used. Moreover, the string-like magnet members 214a, 214b, and 214c may be magnetized so that the two polarities of N polarity or S polarity are alternated in the longitudinal direction. Since the string-like magnet members 214a, 214b, and 214c are provided with various polarities, the directions of the magnetic fields intersect with each other in a complicated manner, thereby improving the degree of influence on the body and further improving health.

  In the present embodiment, the main body 210 is formed in a substantially circular shape in cross section. However, the present invention may be configured to have other shapes such as a cross-sectional view, an ellipse, an ellipse, a star, and a polygon without being limited by this shape. The string-like magnet member 210 may be spiral. In that case, the linear string-like magnet members 214a, 214b, 214c and the string-shaped core member 212 may be spirally twisted. Moreover, the string-like core member 212 may be formed by being twisted in the direction around the center thereof, and at this time, the string-like core member 212 is preferably twisted once or a plurality of times. Moreover, in order to improve design property, you may change the color of the string-like magnet members 214a, 214b, and 214c, respectively.
