  The present invention relates to a marriage ring or pairing between lovers, and relates to a ring such as a ring or a bracelet.

A conventional ring is made of a noble metal material in a ring shape, a jewel is attached to the ring shape, or a pattern is formed on the surface of the ring. Among these rings, couples of couples and lovers use the same shape (design), the same pattern (letters), the same jewels, etc., and a pair of two that gives a sense of unity and closeness due to their commonality I often wear a pairing. In this pairing, a technique for pairing a wedding ring or lovers in which characters and patterns are displayed on an end face when two pairs of pairings are fitted together is disclosed (References 1 and 2).
Japanese Patent Laying-Open No. 2003-299511 ([0005 to 0006], [FIGS. 1 and 2]) JP-A-2004-65830 ([0004], [FIGS. 2, 4, 5])

  However, in the above-described prior art, when two pairings of two pairs are fitted together, letters and figures that emphasize the sense of solidarity between couples and lovers are displayed, and a sense of unity is obtained conceptually. It is excellent in meaning, but it is not realistic and physically attractive pairing.

  The present invention has been made to solve the above-described problems, and is suitable as a marriage ring or a pairing between lovers, and a pair of two pairs are physically attracted or attracted to each other. It is a pairing that creates a sense of unity and intimacy for couples and lovers, and provides rings such as rings and bracelets.

  The pairing according to claim 1 of the present invention for achieving the above object is a pairing comprising two pairs of rings or bracelets, and each ring has magnetic poles different from each other formed on the outer circumferential surface of the ring. It is characterized by that.

  According to this configuration, when one of the rings constituting the pairing is brought closer to the other, a force attracting the N pole and the S pole, which are different magnetic poles, acts and can finally be attracted. When the lovers and the like bring their fingers and arms fitted with the rings closer to each other, the suction and suction generated in the pairing can bring out a sense of unity and intimacy between the lovers.

  Further, the pairing according to claim 2 is the pairing according to claim 1, wherein the permanent magnets forming the magnetic poles are embedded in the ring main body by arranging one or more permanent magnets in the ring radial direction, and The ring body is made of a non-magnetic metal, synthetic resin, or wood.

  According to this configuration, the magnetic pole can be formed on the outer peripheral surface of the ring so as to be exposed or slightly hidden. For example, an N pole can be formed on one ring outer peripheral surface of the pairing, and an opposite S pole can be formed on the other ring outer peripheral surface. Further, if a plurality of permanent magnets are embedded, even if the ring rotates with respect to the finger or the arm, it is possible to always ensure the attractive force or the attractive force regardless of the position. In addition, since the ring body is made of non-magnetic metal, synthetic resin, or wood, it does not disturb the action of the magnetic lines of force of the permanent magnet embedded in the ring body.

In particular, a bonded magnet containing nylon resin or epoxy resin is not brittle, has good moldability, and can produce a ring having a complicated shape or pattern.

  Further, the pairing according to claim 6 is characterized in that, in the pairing according to any one of claims 2 to 5, a noble metal film or a titanium nitride film is fixed to the ring surface of the pairing.

  The pairing according to claim 7 is the pairing according to claim 6, wherein the noble metal film or the titanium nitride film is a film deposited by ion plating, sputtering or CVD.

    According to these configurations, a metal material, a synthetic resin, a tree, and a permanent material constituting the ring are formed by firmly forming a film such as a gold noble metal film, a golden titanium nitride film, a platinum or silver metal film on the ring surface. Since the color of a magnet made of a magnet or a magnetic material can be masked with a decorative color of a film such as a noble metal, the aesthetic value of pairing as a decorative product can be increased. Further, when the pairing is worn, the coating can prevent the ring surface from being corroded or discolored due to human sweat or water work. In particular, it is possible to prevent the surface of the neodymium-iron-boron magnet from being easily corroded.

  According to the pairing of claims 1 to 5 according to the present invention, the ring is composed of two pairs of rings or bracelets, and one or more or a plurality of different magnetic poles having a large residual magnetic flux density are provided on the outer peripheral surface of each ring. Since it is formed uniformly over the outer periphery, when two people wear it on their arms or fingers as a pair of wedding rings or lovers, the pairing may attract or attract each other when the rings are brought close to each other Because you can, you can create a sense of closeness and intimacy between the two. Moreover, the sound when pairing adsorbs can also promote a sense of unity between the two. In addition, as a magnet, a permanent magnet of a ferrite magnet or a rare earth magnet can be embedded in the ring, or a ferrite or rare earth magnetic material or a ferrite or rare earth bonded magnet can be used. In addition, a residual magnetic flux density that increases the attractive force can be obtained, and in the case of a magnetic material or a bonded magnet, an economical added value can be added by adopting a structure in which the ring can be easily molded and decorated.

It is. 2A and 2B show another embodiment of pairing according to the present invention, wherein FIG. 2A is a schematic perspective view, FIG. 2B is a cross-sectional view taken along the line AA, and FIG. 2C is a cross-sectional view taken along the line BB. FIG. FIGS. 3A and 3B show another embodiment of pairing according to the present invention. FIG. 3A is a schematic perspective view, FIG. 3B is a cross-sectional view taken along the line AA, and FIG. FIG.

  The pairing 1 according to the present invention will be described with reference to FIGS. 1, 2, and 3. The pairing 1 is a pair of rings or bracelets, and consists of a male ring and a female ring. Large for men and small for women. 1, 2 and 3 represent male (large) and female (small) rings.

  FIG. 1 is a pairing 1 in which a single permanent magnet 2 is embedded in a decoration stand 1b, and is installed so that the magnetic poles of the permanent magnet 2 appear in the radial direction. As shown in FIGS. 1B and 1C, the magnetic poles appearing on the outer peripheral surface of the ring are the S poles for the female ring if the male ring is the N pole, as shown in FIGS. It arrange | positions so that it may become. The ring main body 1a and the decoration stand 1b are usually formed integrally, and the material thereof is preferably a nonmagnetic metal, a synthetic resin, or wood through which the magnetic lines 5 of the permanent magnet 2 are transmitted. As the nonmagnetic metal, platinum, gold, silver, copper, aluminum, brass or the like can be used, and it is formed by casting or injection molding. In this case, since the temperature is high at the time of molding, the permanent magnet 2 needs to be fixed in the cold state after finishing the ring body 1a. As the synthetic resin, polystyrene, polypropylene or the like suitable for injection molding can be used, or polyethylene, vinyl chloride or the like suitable for blow molding can be used. In this case, the permanent magnet 2 can be wrapped as a core during molding. Further, when the permanent magnet 2 is disposed so that the magnetic pole of the permanent magnet 2 is not exposed on the outer peripheral surface of the ring, it is desirable that the thickness of the material of the ring main body 1a covered with the magnetic pole is as thin as possible from the viewpoint of reducing the magnetic flux density of the magnetic lines 5. In addition, the permanent magnet 2 is disposed in the decoration table 1b so that the permanent magnet 2 is fitted into the decoration table 1b so that the permanent magnet 2 does not come out due to a reaction force against the attractive force exerted by the magnetic force lines 5 between the pairings 1. It is necessary to respond by bonding. Further, the cross-sectional shape in the radial direction of the ring main body 1a may be any of a circular shape, an oval shape, or a triangular shape. Further, the pairing 1 provided with a single permanent magnet 2 has no problem because the direction of the magnetic force line 5 is determined as a ring and the ring does not rotate with respect to the finger, but the bracelet has a large diameter, Because it can rotate freely around the wrist and arm, the direction of the magnetic force line 5 between the pairing 1 is difficult to determine with respect to the circumferential direction. is there. Moreover, even if there is a cut in the ring main body 1a of the ring, there is almost no adverse effect on the action and effect of the magnetic lines 5 of the permanent magnet 2.

  The permanent magnet 2 is preferably a permanent magnet 2 having a high residual magnetic flux density that increases the attractive force or attractive force between the pairings 1, and a ferrite magnet or a rare earth magnet is used. As the ferrite magnet, a Ba ferrite magnet or an Sr ferrite magnet is suitable, and the residual magnetic flux density is in the range of 0.2 to 0.4T. Use of neodymium FeB magnets as the rare earth magnets is more economical than samarium Co magnets, and their residual magnetic flux density is in the range of 0.9 to 1.3 T. Ferrite magnets have a lower residual magnetic flux density than rare earth magnets, but are economical. In addition, since these permanent magnets 2 are sintered products, it may be necessary to fix a noble metal-based film or the like on the surface when they come out as a part of the surface of the decorative product.

  FIG. 2 shows a pairing 1 in which a plurality of permanent magnets 2 are embedded in a ring body 1a, and the permanent magnets 2 are installed so that the magnetic lines of force 5 of each permanent magnet 2 appear in the radial direction. The magnetic field lines 5 appearing on the outer peripheral surface of the ring 1a are used to adsorb the rings of the pairing 1 as shown in FIGS. 2B and 2C. It arrange | positions so that it may become a south pole. The material of the ring body 1a is as described in [002], and is preferably a nonmagnetic metal, a synthetic resin, or wood through which the magnetic lines 5 of the permanent magnet 2 are transmitted. In the case where the magnetic poles of the permanent magnet 2 are not exposed on the outer peripheral surface of the ring, it is desirable that the thickness of the material covering the magnetic poles be as thin as possible in order not to reduce the magnetic flux density. Further, the permanent magnet 2 is disposed in the ring body 1a so that the permanent magnet 2 is fitted into the ring body 1a so that the permanent magnet 2 does not come out due to a reaction force against the attractive force exerted by the magnetic force lines 5 between the pairing 1. It is necessary to respond by bonding. The radial cross-sectional shape of the ring main body 1a may be any of a circle, an oval, or a polygon more than a triangle, but a quadrangle is desirable in terms of the effect of the lines of magnetic force 5. Further, since the pairing 1 provided with a plurality of permanent magnets 2 has little directivity in the circumferential direction of the magnetic force lines 5, it can be attracted by a ring or a bracelet that can freely rotate around a wrist or an arm. There is no problem in exerting force or adsorption power. Further, the arrangement of the plurality of permanent magnets 2 is not necessarily arranged uniformly over the entire circumference of the ring, and may be biased. Moreover, even if there is a cut in the ring main body 1a of the ring or bracelet, there is almost no adverse effect on the effect of the magnetic lines of force 5 of the permanent magnet 2. The permanent magnet 2 is as described above.

  In the pairing 1 shown in FIG. 3, the ring main body 1a is magnetically molded with a magnetic material to add radial anisotropy, and a predetermined processed molded product is magnetized in the radial direction so that the outer peripheral surface of the ring main body 1a ( For example, the magnetic poles are formed on the N-pole) and the inner peripheral surface (for example, the S-pole), the residual magnetic flux density can be increased, and the directivity of the magnetic lines 5 in the radial direction (circumferential direction) can be eliminated. . Further, as the magnetic material, any one of a ferrite material, a rare earth material, a ferrite bond magnet material, or a rare earth bond magnet material is used.

  In the case of a ferritic material, it is Ba ferrite or Sr ferrite, and the ring body 1a is adjusted to a component suitable for magnetism, and then the ring body 1a is added so that radial anisotropy is added to the pulverized fine magnetic material. It is a sintered product obtained by forming a magnetic field into a magnetic field and then sintering it. Therefore, as a decorative product, after grinding, a noble metal film or titanium nitride film is deposited by ion plating, sputtering or CVD to coat the coating 4, and then magnetized in the radial direction to produce the ring body 1a. To do. Thus, the pairing 1 having different magnetic poles can be manufactured. In the case of a rare earth material, it is a neodymium FeB material, and its ring body 1a is adjusted to a component suitable for magnetism, melted and cast, and a fine magnetic material made by pulverizing the cast product is radial. This is a sintered product which is magnetically molded on the ring body 1a so as to add anisotropy, then sintered, and then subjected to an aging treatment. Therefore, as a decorative product, after grinding, a noble metal film or titanium nitride film is deposited by ion plating, sputtering or CVD to coat the coating 4, and then magnetized in the radial direction to produce the ring body 1a. To do. Thus, the pairing 1 having different magnetic poles can be manufactured.

  In the case of a bonded magnet, a thermoplastic nylon resin is mixed with the above-mentioned ferrite-based or rare-earth-based magnetic material, and injection molding is performed on the ring body 1a in a magnetic field so as to add radial anisotropy. A thermosetting epoxy resin is mixed with a base or rare earth magnetic material and compression-molded in a magnetic field on the ring body 1a so as to add radial anisotropy. After the curing process, the ring body 1a of the bonded magnet is manufactured. The ring main body 1a of these bonded magnets has a good moldability, a ring main body 1a having a complicated shape or pattern is obtained, and also has a good workability and is ground as a decorative article, and then is precious metal film or nitrided. A titanium film is deposited by ion plating, sputtering or CVD to coat the coating 4, and then magnetized in the radial direction to produce the ring body 1a. Thus, the pairing 1 having different magnetic poles can be manufactured. The residual magnetic flux density of the ring main body 1a thus obtained, that is, the bonded magnet, is 0.2 to 0.3T for Ba or Sr ferrite magnets, and 0.55T for neodymium FeB magnets. The compression and compression moldings are about 0.70 T, and sufficient suction force or adsorption force can be obtained. Further, since the bonded magnet is not easily broken and can be integrally formed with a metal, a synthetic resin, or the like, a pairing 1 in which the bonded magnet and the nonmagnetic material are combined can also be manufactured.

It can be used as a pairing that is a decorative item worn by two people in a wedding ring or between lovers.
