Description

  The present invention relates to a magnetic necklace provided with a permanent magnet so that magnetism is applied around the neck.

  Patent Document 1 (Japanese Utility Model Publication No. 7-11919) is far from the surface of beads, tubes, connectable plates, or polymorphic pieces made of wood, plastic, glass, ceramic, magnetic material, metal or the like. Disclosed is a far-infrared radiation necklace for health that also serves as a decoration in which a bead shape is formed by applying an infrared radiation paint and a hook or can is provided at both ends.

  Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-166895) discloses a permanent magnet ring configured by arranging a plurality of permanent magnets on a ring. In the permanent magnet ring, a through hole is formed in each of the permanent magnets, and the permanent magnet is movably mounted on the ring by passing the ring through the through hole. is there. Further, the magnetic poles opposed to each other of the permanent magnets adjacent to each other are arranged so as to have the same polarity, and are magnetically repelled from each other so that a predetermined interval is opened on the ring.

  Patent Document 3 (Japanese Patent Application Laid-Open No. 2009-18061) is a magnetic treatment instrument that is used in a necklace or the like and has a blood circulation promoting action on the body, and is made of a resin and a plurality of granular solid substances magnetized. Disclosed is a magnetic therapy instrument, a so-called magnetic necklace, in which a plurality of solid parts having a property are disposed and the plurality of solid objects are arranged at positions separated from each other in a state of being covered with the resin.

  In the necklace disclosed in the above-mentioned Patent Document 1 or 2, since it is necessary to form a hole for passing a string through each of the component pieces, there is a problem that it takes time for processing, and the component piece is directly on the skin. When touched, the skin feels uncomfortable, and the corners of the component pieces cause damage to the skin.

  In addition, in the necklace disclosed in Patent Document 3, since a plurality of granular solid objects magnetized in the resin are mixed so as to be separated from each other, the polarity of the magnetic material becomes random, so that magnetism is effective. There was a bug that did not work.

  Therefore, in order to solve the above-mentioned problems, the present inventor has devised a magnetic necklace in which a component piece provided for health is easily formed in a necklace shape without directly contacting the skin (utility model registration number 1). 3160556).

  Since the magnetic necklace falls under the category of home permanent magnet magnetic therapy device, the standard for home permanent magnet magnetic therapy device established by the Ministry of Health, Labor and Welfare Notification No. 119 in 1998, “contacts the affected area for each magnet using a magnetic flux density meter. It is stipulated that the maximum magnetic flux density when the surface magnetic flux density of the portion to be measured is 35 mT or more and 200 mT or less (hereinafter referred to as a predetermined magnetic flux density) is not set to be larger than the predetermined magnetic flux density. For this reason, in the magnetic necklace according to Utility Model Registration No. 3160556 by the present inventor, the shape of the permanent magnet arranged in the necklace is a cylindrical shape, and the direction in which the magnetic lines of the permanent magnet are emitted In the direction along the necklace, the magnetic flux density on the side of the necklace is lowered and the magnetic flux density is It had to fit within.

  However, from a design point of view, it is desirable that the permanent magnets and spherical materials made of other materials contained in the interior have the same size and shape, and that the materials are manufactured in the same size and shape. Is desirable.

  However, if the permanent magnet has a spherical shape as in the case of other materials, it is difficult to make the direction of the line of magnetic force of the permanent magnet constant, so the maximum magnetic flux density depends on the direction of the line of magnetic force of the permanent magnet. Exceeds the predetermined magnetic flux density.

  Therefore, in the present invention, even if the permanent magnet is formed in the same size and shape as other materials, particularly in a spherical shape, the maximum magnetic flux density is in the range of 35 mT to 200 mT (hereinafter, predetermined magnetic flux density). It is to provide a magnetic necklace.

  The present invention comprises a necklace body part and a stopper part that joins both ends of the necklace body part, and the necklace body part is disposed in an elongated bag-like member and the bag-like member. In a magnetic necklace comprising a magnet part and a gap adjusting part arranged between the permanent magnet parts, the permanent magnet part is composed of at least two spherical permanent magnets magnetically bonded, and the gap adjusting part is a non-magnetic material. It consists in at least one spherical member formed from.

  The bag-like member of the necklace body is preferably an elongated cylindrical member made of a natural material or a synthetic material, or an elongated cylindrical member made of a synthetic resin. This makes it possible to use magnetic necklaces for those who have metal allergies.

  Further, since the permanent magnet part magnetically joins at least two spherical permanent magnets and is housed in the bag-like member of the necklace body part, the magnetic lines of force of the permanent magnet part are in a direction along the necklace body part. Become. For this reason, it becomes possible to reduce the maximum magnetic flux density of the said permanent magnet part in the range of 35 mT or more and 200 mT or less (henceforth, predetermined magnetic flux density).

  In the present invention, it is desirable that the distance adjusting unit is a spherical member made of resin (plastic). However, natural stones such as tourmaline and quartz may be formed in a spherical shape. This makes it possible to add value to the magnetic necklace.

  As described above, according to the present invention, in the necklace body portion including a plurality of permanent magnet portions and a plurality of interval adjustment portions, the permanent magnet portion is magnetically joined to at least two spherical permanent magnets. Since the direction of the line of magnetic force of the permanent magnet portion can be set along the necklace main body portion, the maximum magnetic flux density of the permanent magnet portion is reduced within a range of 35 mT to 200 mT (hereinafter, a predetermined magnetic flux density). There is an effect that is possible.

It is explanatory drawing of the magnetic necklace which concerns on this invention. It is explanatory drawing of the permanent magnet part of the magnetic necklace which concerns on this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the magnetic necklace 1 according to the present invention is composed of a necklace main body 2 and fasteners 3 positioned at both ends of the necklace main body 2.

  The necklace main body 2 includes a bag-like member 20 in which a cloth such as a natural material such as linen and cotton, a woven fabric made of a synthetic material such as polyester, a knitted fabric, a felt, and a nonwoven fabric is formed in a bag shape of a predetermined length. Alternatively, a cylindrical bag-like member 20 integrally formed of synthetic resin is provided, and a storage member 21 including the permanent magnet portion 4 and the interval adjusting portion 5 is provided inside the bag-like member 20.

  A plurality of permanent magnet portions 4 and interval adjusting portions 5 arranged between the permanent magnet portions 4 are alternately inserted into the bag-like member 20 having both ends opened, and the interior of the necklace body portion 2 is stored. The member 21 is configured. Then, both ends of the bag-like member 20 are respectively closed by the stopper members 3A and 3B constituting the stopper portion 3, thereby enclosing the storage member 21 therein. The stopper part 3 is composed of stopper members 3A and 3B, respectively, and is normally separated, but the necklace body part 2 can be made annular by engaging the stopper members 3A and 3B. is there.

  For example, as shown in FIG. 2, the permanent magnet portion 4 is configured by magnetically bonding at least two spherical permanent magnets 40, and thereby the direction of the magnetic lines of force of the permanent magnet portion 4 is changed to the necklace body portion 2. It can be formed in the direction along. At this time, the magnetic flux density on the side surface B of the permanent magnet unit 4 is lower than the magnetic flux density on the front surface A of the permanent magnet unit 4. As a result, the maximum magnetic flux density of the permanent magnet portion 4 can be reduced within a predetermined magnetic flux density (35 mT or more and 200 mT or less). In this embodiment, two spherical permanent magnets 40 are magnetically bonded. However, the present invention is not limited to this, and three or more magnetic permanent magnets 40 may be magnetically bonded.

  Moreover, the said space | interval adjustment part 5 is the spherical member 50 formed from the several spherical member 50, especially the material of a nonmagnetic material. In addition, the spherical member 50 can adjust the interval between the permanent magnet portions 4 by adjusting the number of the spherical members 50. In this embodiment, the interval between the permanent magnet portions 4 is made uniform, but the permanent magnet portions 4 can be randomly arranged by changing the number of the spherical members.

  Furthermore, although it is desirable to form the spherical member 50 of the gap adjusting portion 5 with a synthetic resin at a low cost, it may be formed using natural stone such as tourmaline or quartz.

  Furthermore, it is desirable that the permanent magnet 40 and the spherical member 50 are formed in the same size.

  Furthermore, the design property of the magnetic necklace 1 is formed as a shape in which the bag-shaped member 20 of the necklace body 2 is made of heat-shrinkable resin and heat-shrinked so as to be in close contact with the spherical permanent magnet 40 and the spherical member 50. May be improved. Examples of the heat-shrinkable resin include polyolefin, polyvinyl chloride, and polyvinylidene fluoride.
