  DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of an element part according to the present invention and a magnetic accessory using the same will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an exploded perspective view of an element part according to the present invention, and FIG. 2 is an explanatory diagram of an internal structure. As shown in the drawings, an element part 1 according to the present invention has a columnar piece 2 made of a rare earth magnet magnetized in a predetermined direction, substantially the same length as or slightly smaller than the columnar piece 2. It is configured as a columnar assembly that is inserted into the center hole 3a of the long cylindrical piece 3 and the openings at both ends of the center hole 3a of the cylindrical piece 3 are sealed with sealing materials 4a and 4b.

  As the columnar piece 2, a columnar piece 2 (see FIG. 8A) having a circular cross section (including an ellipse and an oval shape), and polygonal columnar pieces 2A and 2B having a cross section of an arbitrary number of angles (see FIG. 8B). ) (See (c)), and further, a columnar piece 2C (see FIG. 8 (d)) having an irregularly shaped cross section can be appropriately employed. Among them, when the outer peripheral surface on the magnetic pole (N, S) side is a curved surface having an arcuate cross section as shown in FIGS. Since it rolls smoothly in a predetermined angle range while maintaining the line contact, there is an advantage that a loop having an arbitrary curvature can be easily handled. In the example of FIG. 1, the columnar piece 2 having a circular cross section is employed particularly for the purpose of ease of manufacture and uniform magnetic flux density.

  As the rare earth magnet used as the material of the columnar piece 2, known rare earth magnets such as a neodymium magnet, a samarium cobalt magnet, a praseo magnet, and a samarium iron nitrogen magnet can be appropriately employed. In the illustrated example, although there is a drawback that it is easily rusted and brittle, a neodymium magnet is adopted in consideration of the strong magnetic force.

  As the magnetization direction of the columnar piece 2 made of a rare earth magnet, as shown in FIG. 3A, the N pole and the S pole are polarized in a direction orthogonal to the longitudinal direction with the intention of parallel connection. As shown in FIG. 3 (b), in addition to the magnetization direction in which the N pole and the S pole are polarized in the longitudinal direction, as shown in FIG. A method can be considered. In the example of FIG. 1, with the intention of connecting the element parts 1 in parallel, the magnetization direction shown in FIG. The boundary is divided into two semicircular cross-sectional areas, and a magnetization direction is adopted in which one is an N pole and the other is an S pole.

  As the cylindrical small piece 3, as shown in FIG. 8, the cross-section is a perfect circle, ellipse, oval, polygon having an arbitrary number of angles, or irregular polygons (3, 3A, 3B, 3C). It can be adopted as appropriate. In the example of FIG. 1, a cylindrical body (length: 8.0 mm, outer diameter: 4.0 mm) whose outer cross section is a perfect circle is employed. As described above, when the outer cross section is a perfect circle, a non-perfect circle (including an oval, an ellipse), an irregular polygon, or the like, while maintaining the mutual magnetic adsorption state, Since it rolls smoothly and can be displaced within an appropriate angle range, it is not only a relatively large radius loop collar (necklace), but also a relatively small radius loop loop accessory such as a bracelet or a ring. Even so, it is possible to provide a smooth fit in response to changes in the curvature of the loop. Moreover, it is preferable that the cross-sectional shape of the center hole 3a of the cylindrical small piece 3 matches the cross-sectional shape of the columnar small piece 2 in order for the columnar small piece 2 to be stably stationary in the cylindrical small piece 3.

  As the material of the cylindrical small piece 3, various materials including not only metal but also synthetic resin can be adopted. However, in the parallel connection shown in FIG. In order to generate as much leakage magnetic flux as is effective for magnetic therapy by interposing between the N pole and the S pole at the connecting portion when coupling by attractive force, a non-magnetic material having high magnetoresistance Adoption of (nonmagnetic metal such as aluminum alloy or stainless steel or synthetic resin) is preferable. In addition, it is important that it is difficult to rust due to contact with sweat even after long-term use. From such a viewpoint, stainless steel is adopted as the material of the cylindrical piece 3 shown in FIG.

  The wall thickness of the cylindrical piece 3 is doubled at the connecting portion between adjacent cylindrical pieces to generate a magnetic resistance, and should be determined in relation to the magnetic force of the adjacent magnet. Is.

  As the sealing agents 4a and 4b, any specific structure can be used as long as it can tightly seal the opening at both ends of the cylindrical piece 3. The series shown in FIG. In connection, when adjacent element pieces are coupled with each other by the magnet's attractive force, the coupling portion is interposed between the N pole and the S pole to generate as much leakage magnetic flux as possible for magnetic therapy as much as possible. For this, it is preferable to use a non-magnetic material having a high magnetic resistance. At this time, if the sealing materials 4a and 4b are decorative and workable materials such as synthetic resin and glass, there is an advantage that the aesthetic appearance is excellent.

  Next, the operation of the component part 1 having the above configuration will be described with reference to FIGS.

  An example of a bracelet (bracelet) created using the element part 1 is shown in FIGS. As is clear from these figures, the bracelet 5 is formed by connecting a number of element parts 1 according to the present invention in parallel. That is, as described above with reference to FIG. 3A, when a plurality of element parts 1, 1... Are approached in a parallel state, the columnar piece 2 incorporated in one adjacent element part 1. N poles (or S poles) are attracted to the S poles (N poles) of the columnar pieces 2 incorporated in the other element part 1 so that the plurality of element parts 1, 1, 1. While maintaining the posture, the two elements connected to each other through the magnet's attractive force are attracted to each other in the same manner, so that the magnetic component of the loop-shaped magnetic accessory A bracelet (magnetic bracelet) 5 is completed. At this time, since the columnar piece 2 made of a neodymium magnet is protected by the cylindrical piece 3 and the sealing materials 4a and 4b, it is said that the columnar piece 2 is not chipped or broken by an impact during suction coupling. Have advantages.

  An explanatory view of the bracelet wearing operation is shown in FIG. When the magnetic bracelet (magnetic bracelet) 5 of the present invention is mounted on a person's arm, first, as shown in FIG. 5A, an open loop state in which a plurality of component parts 1 are connected in a parallel posture. A string-shaped element part row is wound around the upper surface of a person's arm.

  Then, since each pair of adjacent element parts is magnetically coupled while contacting each other's cylindrical peripheral surfaces with one line along the longitudinal direction, the individual element parts roll, The string-shaped element part row is curved so as to hang down in an inverted U shape on both sides of the arm due to its own weight. At this time, the individual element parts 1 roll and displace within a predetermined angle range mainly only in a plane orthogonal to the longitudinal direction thereof, so that the above-described string-like element part row is largely twisted when curved. There is no.

  Incidentally, in the case of the spherical element parts (balls) described in Patent Document 1, since the individual element parts are in point contact with each other, they can be freely rolled and displaced in any direction. When applied, when it is wound around the arm, it is bent in an arbitrary direction and twisted, and the mounting operation on the arm is complicated.

  In addition, in the two element parts located at both ends of the string-like element part row in the open loop state, a strong magnetic strength N pole and S pole corresponding to the number of connected element parts appear. For this reason, if the hooks are pulled together at both ends of the string-like element part row in the manner of attaching the watch band to the arm, the element parts located at these two end parts are as shown by arrows in FIG. Since the magnetic bracelet (magnetic bracelet) 5 which is a single loop attracted and attracted by a strong magnetic force and is a closed loop string element component row is completed, the mounting can be completed without difficulty.

  FIG. 6 shows an explanatory diagram of the wearing state of the collar, and FIG. 7 shows a wearing state of the ring. As is clear from these figures, the structure of the collar 6 and the ring 7 is the same as that of the bracelet 5 except that the size of the loop is different from that of the bracelet 5. Description is omitted.

  According to the element part 1 according to this embodiment, since the coupling between the adjacent element parts is due to the line contact between the outer peripheral surfaces of the cylindrical body, it easily corresponds to the loop locus of an arbitrary curvature, By simply increasing / decreasing the number of component parts, it is possible to easily realize magnetic accessories (bracelet 5, collar 6, ring 7) that have different loop diameters and are less likely to rust even after long-term use.

  In addition, since stainless steel, which is a non-magnetic substance having a large magnetic resistance, is interposed between adjacent element parts, a magnetic pole built in one adjacent element part (for example, N pole of a neodymium magnet) And the other element component built-in magnetic pole (for example, the S pole of a neodymium magnet) has a relatively large magnetic resistance, and therefore the magnetic flux from one magnetic pole to the other magnetic pole is greatly curved outward ( Leakage) is caused to pass through a part of the human body, and such magnetic leakage occurs at all joints between the component parts, so that a good magnetic therapeutic effect is expected.

  In the present invention, as shown in FIG. 3 (b), the magnetization direction of the columnar pieces in the element part may be the longitudinal direction. In this case, by connecting them in series, a necklace or the like The large-loop magnetic accessory can be realized with a relatively small number of component parts. Also in this case, since the synthetic resin which is a non-magnetic substance is interposed between the adjacent magnetic poles, it is possible to expect a magnetic treatment effect due to magnetic leakage similar to the above.

  According to the element part of the present invention or the magnetic accessory using the same, when a plurality of columnar assemblies are aligned in the same direction, a magnetic attractive force acts between the adjacent assemblies, and the columnar assemblies Since the bodies are automatically connected to each other, in addition to being able to construct a magnetic accessory that does not require a string or a connecting metal fitting, the columnar piece made of rare earth magnet is protected by a cylindrical piece and a sealing material. Therefore, it has the advantage that it does not chip or break due to impact during suction coupling, and does not rust due to contact with sweat. In addition, there is a nonmagnetic material between the adjacent N pole and S pole. Since the cylindrical small piece or the sealing material is interposed, there is an advantage that the magnetic resistance in the coupling portion is high, and a leakage magnetic flux effective for magnetic therapy is sufficiently generated from the coupling portion.
