  However, a magnetic accessory that exposes metal and cannot be used because it may injure the body during exercise. In addition, the length cannot be easily adjusted, and separate magnetic accessories are required for use in various parts of the body, such as the neck or shoulder and wrist.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic accessory that can be worn safely during exercise without any risk of damaging the body, can be adjusted in length, and can be worn on various parts of the body.

The magnetic accessory of the present invention includes a long body composed of a rubber magnet layer and a protective layer provided on the surface of the rubber magnet layer, and a resin sandwiching member formed on each end of the long body. Magnetic jewelry,
The resin sandwiching member protrudes in a direction substantially perpendicular to the longitudinal direction of the elongated body;
The resin sandwiching member has a through-hole parallel to the longitudinal direction of the elongated body, and a notch parallel to the longitudinal direction of the elongated body on the side surface of the through-hole over the entire length of the through-hole. It is characterized by being formed.

  Further, the resin sandwiching members respectively formed at both ends of the long body are formed so as to have a point-symmetrical orientation when the long body is linearly extended.

  Moreover, the direction of the notch in the cross section perpendicular to the axial direction of the elongated body of the sandwiching member is perpendicular to the protruding direction of the sandwiching member.

The magnetic accessory of the present invention includes a long body composed of a rubber magnet layer and a protective layer provided on the surface of the rubber magnet layer, and two resin sandwich members formed on both ends of the long body. A magnetic accessory comprising:
The two resin sandwich members project in a direction substantially perpendicular to the longitudinal direction of the elongated body;
A through hole parallel to the longitudinal direction of the elongated body, and a notch parallel to the longitudinal direction of the elongated body over the entire length of the through hole on the side surface of the through hole. And formed,
It is formed so as to have a point-symmetrical orientation when the elongated body is extended linearly, and since it has flexibility and the surface is soft, it can be worn even during exercise without any risk of damaging the body. It is safe because it is not applied with strong force. In addition, since the length can be adjusted, it can be worn on various parts such as the neck, arm and wrist, and can be applied to many people with one size. In addition, a plurality of wires can be connected in series.

  Further, since the notch direction of the sandwiching member in the cross section perpendicular to the axial direction of the elongate body is perpendicular to the protruding direction of the sandwiching member, it is unlikely to be disengaged even by intense movement.

  In the long body in which the receiving portion and the insertion body are formed at the end portions, the length cannot be freely adjusted, but the width of the connecting portion can be reduced.

  Further, the sandwiching member in which the receiving portion, the through hole, and the notch are formed is fitted into the insert formed at one end of the long body, and the sandwiching member in which the insert is formed is the long member. In the form fitted into the receiving part formed at the other end of the body, the length can be adjusted, and the pinching member can be rotated and connected, so even if the long body is bent, it is connected in an annular shape Sometimes the connecting part can fit and improve along the body.

  Embodiments of the present invention will be described below with reference to the drawings. In the embodiment, in common, a long body made of a rubber magnet in which ferrite is dispersed in rubber is formed, and the cross section of the long body has a circular shape with a diameter of about 3 to 8 mm. A polyurethane layer having a thickness of about 0.1 to 0.5 mm is provided on the surface of the body. The mixing ratio of ferrite and rubber is suitably 80 to 95% by weight for ferrite and 5 to 20% by weight for rubber. Assuming that the ferrite particles are magnetized in the same direction in the cross section of the long body 1, for example, in the upward direction of the cross section, the adjacent N poles and S poles of the ferrite particles are canceled, and N polarity is present in the upper half of the long body surface. S polarity appears in the lower half. For this reason, the long body 1 is virtually magnetized in an arbitrary cross section of the long body 1 as shown in FIG. Although the direction of magnetization is shown in FIG. 1 so as not to change in the length direction, the direction of the magnetic field lines coming from the north pole is the length direction of the long body, for example, staggered or spiral. Or may change in a random direction, and can be changed so as to increase the magnetic effect.

  As the strength of magnetization, in this embodiment, the magnetic flux density on the surface of the long body is 40 to 70 millitesla. From the mixing ratio of the ferrite and rubber, appropriate flexibility can be obtained, so that it can be easily worn on the body, and the magnetic flux density can be increased within an appropriate range, so that the health promotion effect is high.

  In the following embodiments, the long body has a circular cross section. However, the present invention is not limited to this, and may have other shapes such as an ellipse, a square, and a hexagon. Moreover, coloring and a pattern may be given to the surface of a long body according to liking, and a design is not limited.

Embodiment 1
2 to 6 show a magnetic accessory according to Embodiment 1 of the present invention. In the first embodiment, the resin sandwiching members 2 projecting in a direction substantially perpendicular to the axial direction of the long body 1 at both ends of the long body 1 are point-symmetric when the long body 1 is extended linearly. (See FIG. 2). As shown in FIG. 3, the sandwiching member 2 is formed with a through hole 3 parallel to the axis of the long body 1, and is parallel to the axis of the long body 1 over the entire length of the through hole on the side surface of the through hole. A notch 4 is formed. The direction of the notch 4 is perpendicular to the protruding direction of the sandwiching member in the cross section perpendicular to the axial direction of the long body 1. The sandwiching member 2 is formed of a soft elastomer such as a silicone resin.

  FIG. 4 shows a state in which the magnetic accessory of the first embodiment is connected in an annular shape. A long body is pushed into a through hole of a sandwiching member through a notch and sandwiched. Since the long body has a constant cross section, it can be inserted anywhere and the length can be adjusted (see FIG. 5). Since the sandwiching member 2 is formed in a point-symmetrical direction as shown in FIG. 3 when the elongate body 1 is extended, the elongate body 1 is twisted when connected as shown in FIG. 4 or 5. There is nothing.

  Since the magnetic accessory of the present invention is mainly made of rubber, it can be curled freely. Because the surface is soft, it does not hurt the body and can be worn during exercise. Since the sandwiching member is formed of a soft elastomer, the length can be easily adjusted. Moreover, although it does not slip | deviate by a normal motion, when the strong force more than a fixed level is applied, since the notch 4 will spread and the elongate body 1 will peel, it is safe. Furthermore, a plurality of magnetic accessories according to the first embodiment can be connected to be attached to various parts of the body, or can be used by being wound in two or more layers (see FIG. 6).

  In Embodiment 1, the material of the sandwiching member 2 is a silicone resin, but the material is not limited to this and may be another soft elastomer.

  In order to make the notch wide and easy to attach and detach, and to make it difficult to disengage in normal use, the direction of the notch of the sandwiching member is set in the direction in which the sandwiching member protrudes in the cross section perpendicular to the axial direction of the long body 1 However, the notch direction is not limited to this, and may be, for example, the direction in which the sandwiching member protrudes. Further, in FIG. 2, both ends of the notch are directed toward the front of the drawing in FIG. 2, but may be reversed at both ends (that is, one notch is directed to the back side of the paper surface). However, in this case, the sandwiching member has a mirror surface relationship at both ends of the elongated body, whereas in the form of FIG. 2, the sandwiching member can have the same shape at both ends.

It is formed (see FIG. 7). The insert is a shaft 10 formed of a holding member 9 and a hard elastomer protruding from the surface of the holding member, such as polyacetal, and has a substantially hemispherical shape with a diameter larger than the diameter of the shaft cross section at the tip of the shaft. An engaging portion 11 is formed. The length from the holding member surface to the substantially hemispherical engaging portion is slightly longer than the depth of the narrow portion of the receiving portion (see FIG. 7).

  The receiving portion and the insert in Embodiment 2 can be fitted together. When inserting, the tip of the insert is rounded so that it can be inserted with a small force.However, when inserted completely, the engaging part of the insert is applied to the narrow part of the receiving part, and pulling is not applied unless a certain amount of force is applied. I can't escape. In the case of the second embodiment, the pulling force is about 15N. Further, if the joint portion is bent with the receiving portion and the insert, it can be easily removed.

  FIG. 8 shows a form in which the magnetic accessories according to the second embodiment are connected in an annular shape. In the second embodiment, the length cannot be adjusted freely, but since the long bodies do not alternate at the connection portion, they do not get in the way when worn. In the second embodiment as well, a plurality of magnetic accessories can be connected to one.

  In the second embodiment, the receiving portion is made of silicone resin and the shaft of the insert is made of polyacetal. However, the present invention is not limited thereto, and the receiving portion is made of a soft elastomer, and the shaft of the insert is made of, for example, polyamide or polycarbonate.
