[0006] Other objects and novel features of the present invention will be clarified in embodiments described later.

[0007]

In order to achieve the above object, a magnetic belt according to the present invention is provided with a magnet pad having a plurality of neodymium magnets and arranged in such a manner that the magnetic poles of adjacent neodymium magnets are opposite in direction. A contact support having an attachment means on the inner surface for detachably attaching the magnet pad, a telescopic portion extending to both sides of the contact support, and a female surface extending to the distal end side of both telescopic portions and an outer surface. A belt body having a tip engaging portion having a fastener, a male surface fastener provided on the inner surface of one of the tip engaging portions and capable of engaging with the female surface fastener of the other tip engaging portion; A fastening elastic band portion which is connected to the contact support portion, extends to both sides, and has a male surface fastener capable of engaging with the female surface fastener is provided on the inner surface of the distal end portion.

[0008] In the magnetic belt, the magnet pad may have a configuration in which the neodymium magnet is embedded in a flexible sheet such that a side facing the affected part is a convex part.

Preferably, the flexible sheet is a silicon rubber sheet having ventilation holes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the magnetic belt according to the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 5 show an embodiment of a magnetic belt according to the present invention. In these figures, reference numeral 1 denotes an abutting support portion which comes into contact with an affected part such as a waist or the like, which has a fastener 2 as an attachment means for detachably attaching the magnet pad 20 as shown in FIG. ing. The contact support portion 1 is a cloth having good air permeability, is lined with a reinforcing cloth material, has sufficient strength, and the fastener 2 is fixed to a plurality of portions of the contact support portion 1.

A mesh-shaped expansion / contraction part 3 having good air permeability is connected (sewn) to the contact support part 1, and
Extends on both sides. Further, a distal end engaging portion 4 is extended (sewn) on the distal end side of both the elastic portions 3. A female hook-and-loop fastener 5 is provided (sewn) on the outer surface of each tip engaging portion 4. A male hook-and-loop fastener 6 is provided (sewn) on the inner surface of the tip portion of one tip engaging portion 4 so as to be freely engageable with the female hook-and-loop fastener 5 of the other tip engaging portion 4. Has become.

A belt main body BT is constituted by the contact support portion 1, the fastener 2, the extension portion 3, the tip engagement portion 4, the female surface fastener 5, and the male surface fastener 6.

A fastening elastic band portion (rubber band portion) 10 is fixed (sewed) to the outside of the contact support portion 1, and extends to both sides of the contact support portion 1. The length of the left and right tightening elastic bands 10 is set shorter than the length of the belt body BT, and the (sewn) male surface provided on the inner surface of the distal end portion of the tightening elastic band 10. Fastener 11
Is freely engageable with the female surface fastener 5 of the tip engaging portion 4.

As shown in FIG. 3, a magnetic pad 20 is provided with a plurality of neodymium magnets 21 (Nd-Fe-B based magnets) in a silicon rubber sheet 22 as an elastic flexible sheet, and adjacent neodymium magnets. 21 are arranged at predetermined intervals so that the directions of the magnetic poles are opposite. FIG.
As shown in (1), each neodymium magnet 21 is embedded in the silicone rubber sheet 22 so that the side facing the diseased part such as the waist becomes the convex part 23. The convex portion 23 formed on the silicone rubber sheet 22 presses the affected part when it is attached, and exerts a finger pressure effect.

The silicon rubber sheet 22 has a plurality of mounting holes 24 and ventilation holes 25 corresponding to the fasteners 2 on the contact support portion 1 side. Since the silicone rubber sheet 22 has flexibility, the silicone rubber sheet 22 can be easily fitted and locked in the fastener 2 with the mounting hole 24 expanded.

The neodymium magnet 2 in the magnetic pad 20
The number of 1 is 70, the surface magnetic flux density of each magnet 21 measured on the surface of the silicon rubber sheet is 180 to 200 mT, and the magnetic poles of the adjacent neodymium magnets 21 are set to mutually opposite polarities. It is capable of emitting sufficiently strong magnetic lines of force.

Next, how to use the magnetic belt according to the present embodiment will be described.

The mounting hole 24 of the magnetic pad 20 is fitted into the fastener 2 on the contact support portion 1 side, and the magnetic pad 20 is attached to the contact support portion 1.
Attach to Then, the contact support portion 1 is brought into contact with the affected part of the body where back pain or the like has occurred, and the belt is placed so that the convex part 23 of the silicon rubber sheet 22 containing the neodymium magnet 21 is pressed against the affected part. Tighten the body BT around the body. That is, the elastic portion 3 is extended, and the male surface fastener 6 of the one end engaging portion 4 is engaged with and fixed to the female surface fastener 5 of the other end engaging portion 4. Thereafter, the tensioned elastic band portion 10 extended to both sides is pulled,
The male surface fastener 11 on the inner surface of the distal end portion is engaged with and fixed to the female surface fastener 5 on the outer side of the distal end engaging portion 4. Thereby, the belt BT can be further tightened by the force in the contraction direction of the tightening elastic band portion 10 and the magnetic pad 20 of the contact support portion 1 can be securely brought into close contact with the affected part such as the waist.

When magnetic flux passes from the N pole of the neodymium magnet 21 of the magnetic pad 20 closely attached to the affected part to the S pole of the adjacent neodymium magnet 21, sufficiently strong magnetic lines of force can be emitted to the affected part. Also, the protrusions 23 of the silicone rubber sheet 22
By pressing the affected part, an acupressure effect can also be obtained.

According to this embodiment, the following effects can be obtained.

(1) A sufficiently strong magnetic field can be generated in a wide range by using the neodymium magnets 21 as the magnets arranged on the magnetic pad 20 and increasing the number of mountings, and the polarities of the neodymium magnets 21 are alternately reversed. With this arrangement, sufficient lines of magnetic force can penetrate into the affected area.

(2) The magnetic pad 20 is provided with magnets on the flexible silicon rubber sheet 22, has elasticity, and can be easily attached to and detached from the contact support portion 1. In addition, the convex portion 23 is formed on the surface facing the affected part, so that a finger pressure effect can be exerted.

(3) The contact support portion 1 and the expansion / contraction portion 3 constituting the belt body BT are made of a material having good air permeability,
0 has a large number of ventilation holes 25, has a structure that does not allow the whole to have good ventilation, and is slim (thin). Also,
The contact support portion 1 is lined with a reinforcing cloth material, has sufficient strength, and also has a corset function. Further, the double fastening structure including the fastening elastic band portion 10 can improve the wearability on the body.

The attachment means for attaching the magnetic pad 20 to the contact support 1 can be changed as appropriate. Also,
The position and number of each neodymium magnet in the magnetic pad can be changed as appropriate.
