  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.

Embodiment 2

In the second embodiment, the receiving portion 5 and the insert 8 are formed at the end of the long body 1. The receiving part 5 has a hole 6 having an opening formed on the surface of a member made of a soft elastomer, for example, silicone resin, and a narrow part 7 having a diameter smaller than the opening of the hole is formed in the middle part in the depth direction of the hole. 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 having 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. Or a hard elastomer.

  As in the case of the receiving portion in the second embodiment, the sandwiching member 12 in which the receiving portion is formed has a hole 6 having an opening formed on the surface of a member made of a soft elastomer, for example, silicone resin, and the depth of the hole. A narrow portion 7 having a smaller diameter than the opening of the hole is formed in the middle portion in the direction. Moreover, the through-hole 3 and the notch 4 are formed similarly to the clamping member in Embodiment 1 (refer FIG.9 (b)).

  As in the case of the insert in the second embodiment, the sandwiching member 13 formed with the insert is a holding member 9 and a shaft 10 formed of a hard elastomer projecting from the surface of the holding member, for example, polyacetal. A substantially hemispherical engaging portion 11 having a diameter larger than the diameter of the axial cross section is formed at the tip of the shaft. Moreover, the through-hole 3 and the notch 4 are formed similarly to the clamping member in Embodiment 1 (refer Fig.9 (a)).

  The sandwiching member 12 in which the receiving portion is formed is fitted into the insert 8 formed at one end of the long body, and the sandwiching member 13 in which the insert is formed is inserted into the receiving portion formed in the other end of the long body. In the same manner as in the first embodiment, the elongated member is sandwiched and used (see FIG. 10).

  The magnetic accessory according to the third embodiment can be adjusted in length, and can be connected in any direction by rotating the sandwiching member. Therefore, even when the elongated body is bent, it is connected when connected in an annular shape. The part can fit and improve along the body. Further, according to preference, it is possible to connect as in the second embodiment, and one magnetic accessory can be used properly. Also in Embodiment 3, a plurality of magnetic accessories can be connected to form one. Further, it may be used in combination with the magnetic accessory of the first embodiment.
