Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an insole that is used by being inserted into a shoe for the purpose of promoting health.

[Conventional technology]

Conventionally, various kinds of insoles with magnets have been developed and used to promote health.
One such insole is shown in FIGS. 7 and 8. As shown in the figure, the insole is provided with a pocket 31 in the arch portion of a leather insole main body 30.
A plate-shaped rubber 32 containing a magnet is attached to the plate.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional insole, since the plate-shaped rubber 32 is composed only of a rubber material mixed with a magnet, there is a problem that cracks appear from the side surface and the insole becomes unusable in a short period of time. Furthermore, since only a portion of the insole main body 30 has magnetic force, it is not possible to provide a magnetic effect over the entire foot.

The present invention was devised in view of these conventional problems, and the purpose is to provide an insole that can provide a sufficient magnetic effect to the entire sole of the foot, has a long life, and can be manufactured at low cost. shall be.

[Means for solving problems]

In order to achieve this purpose, the insole of the present invention is made by superposing a rubber magnet plate 3 made of a mixture of magnetic material and rubber and having the same shape as the fabric plate 2 on a fabric plate 2 having the shape of the sole of the foot. Main body 1
The rubber magnet plate 3 is formed from a flat plate part 3a, a large protrusion 5 with a high height protruding from the flat plate part 3a, and a small protrusion 6 lower than the large protrusion 5, and the large protrusion 6 on the back surface of the insole main body 1 A protrusion 7 is arranged at a position corresponding to the protrusion 5 and the small protrusion 6, the large protrusion 5 is arranged to be located at the arch of the foot, and a large number of through holes 8 are provided in the insole main body 1. It is characterized by

〔Example〕

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

FIG. 1 is a surface view of the insole according to the present invention;
FIG. 2 is a back view of the same, and FIG. 3 is a sectional view taken along the line of FIG. 1.

In FIG. 1, 1 is the insole body;
The entire shape is formed to be the shape of a shoe sole plate.

In addition, as shown in FIG. 3, the insole main body 1 is made of a material plate 2 having sufficient strength and flexibility, such as a cotton woven fabric or a nylon fiber woven fabric, and magnetically attached to the front and back surfaces thereof, respectively. Thin rubber magnet plates 3 and 4 made of a mixture of material and rubber material are integrally formed.

Furthermore, as shown in FIGS. 1 and 3, the rubber magnet plate 3 has different shapes and sizes on its surface.
It has large protrusions 5 and small protrusions 6 made of the same material as the flat plate part 3a, and a plurality of large protrusions 5 are provided at locations corresponding to the so-called arches, and small protrusions 6 are provided at equal intervals at other locations. ing. this is,
This is because the projections conform to the shape of the foot and come into uniform contact with the entire sole of the foot, providing the same stimulation effect.

The shapes and dimensions of the large protrusion 5 and the small protrusion 6 can be selected as appropriate, but for example, the large protrusion 5 has a height of 5.5 mm and a diameter of 8.0 mm, and the small protrusion 6 has a height of 5.5 mm and a diameter of 8.0 mm. Good results were obtained by setting the diameter to 1.5 mm and the diameter to 5.0 mm.

Further, the magnetic force of the large protrusion 5 and the small protrusion 6 can be arbitrarily determined, but is preferably 500 to 1500 Gauss. The magnetic force can be easily adjusted by changing the size and shape of the protrusion.

On the other hand, regarding the rubber magnet plate 4 as well, the large protrusion 5
and a protrusion 7 at a location corresponding to the small protrusion 6, which can prevent the insole from adhering to the sole of the shoe due to perspiration, etc., and can also form a ventilation space between the insole and the sole of the shoe. It can promote the evaporation of sweat and prevent stuffiness.

Further, reference numeral 8 denotes a large number of through holes provided in the flat plate portion 3a of the insole main body 1, which are provided in order to improve air permeability and prevent stuffiness.

In addition, in the above embodiment, the insole body 1
Although the dough plate 2 is sandwiched between the rubber magnet plates 3 and 4 in a polymerized form, the material plate 2 is not limited to this, and may also have a polymerized form shown in FIGS. 4 and 5, for example.

FIG. 4 shows a dough plate 21 glued to one side of a single rubber magnet plate 20, and FIG. 5 shows a dough plate 23 and 24 glued to both sides of a single rubber magnet plate 22. It is something.

Note that any side of the insole having the above configuration can be used as the surface. For example, it is conceivable to initially use the lower surface in FIG. 1 as the front surface, and then use the upper surface as the surface after getting used to it.

Next, a method for manufacturing an insole having the above structure will be explained with reference to FIG.

A nitrile rubber plate in a vulcanized state and ferrite magnetic powder (particle size: 0.93 to 0.95 μm) are mixed in a ratio of 1:8 to 1:8.
Prepared in raw material adjustment step 11 at a ratio of 10. A plate of nitrile rubber is compressed with rollers in a kneading step 12, and at this time, it is formed into a plate shape of uniform thickness while mixing magnetic powder. Next, in the vulcanization press and dough material insertion step 13, approximately
Heating it to 170℃, putting the rubber between two hot plate molds, and putting the dough plate at the same time, applying pressure and vulcanizing. The time required for the vulcanization press is 3 to 4 minutes. next,
A die-cutting operation is performed in a die-cutting step 14, the product is taken out, and the surface is painted in a painting step 15.
At this point, the magnetic force of the molded product is still low, so
Apply magnetic force to the molded product using a magnetizer. By magnetizing in the magnetizing step 16 in this manner, a finished product 17 is obtained.

[Effect of idea]

As mentioned above, in this invention, the large protrusions and small protrusions made of rubber magnets are formed so as to protrude from the surface, and the large protrusions are placed in the arch of the foot, thereby creating a magnetic effect over the entire foot. It is possible to achieve a synergistic effect of shiatsu and acupressure. Furthermore, since the rubber plate is integrally formed with a fabric having sufficient shear strength, it can be used for a long period of time without cracking. Furthermore, since it has flexibility throughout, it can provide a good contact feeling to the foot.
