Description

[Detailed description of the invention] [Industrial field of application] The present invention is an elastic material used for clothing worn on the human body so that the external shape of the clothing is maintained normally by blocking external pressure. The present invention relates to a core material for clothing.

[Prior Art] Conventionally, the core materials used for human clothing include those using a round wire in a curved shape as shown in Figure 4, and those using a semicircular plate as shown in Figure 5. There are known products that are cut into a curved shape.

All of the above-mentioned curved bodies are curved into a substantially U-shape to match the body shape.

When used in the shape of the material mentioned above, it has sufficient strength to some extent, but it tends to deform when subjected to external pressure, such as when washing, and it is difficult to restore it to its original shape by hand. It was necessary to correct it through processing.

In order to eliminate such practical drawbacks, it has been considered to use shape restoration as a basis, and such a technique is known as disclosed in Japanese Patent Application Laid-Open No. 13706/1983.

That is, the shape memory alloy according to this technique is processed into a fibrous wire, which is knitted into a shape that matches the shape of the human body, and after being subjected to shape memory treatment, is sewn into cloth to make clothing.

[Problems to be solved by the invention] However, in the case of this technology, processing the thin fibrous wire material that matches the shape of the clothing, that is, the shape of the human body, and then knitting the cloth requires a significant increase in man-hours, and furthermore, the manufacturing cost rises. It is clear what to do.

Moreover, if the human clothing is expected to return to its shape, it needs to be constructed so that when it comes into close contact with the human body, it senses the body temperature and quickly restores its shape.

In view of the above-mentioned prior art, the present invention utilizes an elastic material or a shape memory alloy to bend a spring elastic material that can return to its shape so that it conforms to the curve of the human body, thereby preventing unexpected deformation due to external pressure. Since it is possible to effectively prevent the above-mentioned wear and tear, and to maintain the clothing always stretched through the core material, it is possible to provide a core material with a long lifespan.

In addition, since the base plate is twisted inward, it always falls in the direction of the human body even when external pressure is applied, so that the clothing can be prevented from being damaged.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a core material made of a flat elastic material bent into a semicircular shape. It was constructed as a core material for clothing having a base part twisted so as to face oppositely to each other.

[Function] This core material is bent into a semicircular shape and twisted so that it faces inward, so that it always falls inward toward the human body even if it receives external pressure. Because it is a material, it can be used without causing any abnormality to the human body, and its bending prevents unexpected damage to clothing.

In addition, a plate material is used as the substrate part, and the surface is pressed against the outer surface of the body part. The plate shape can be used to surround and hold the body part.

[Embodiment] The present invention will first be described in detail with reference to the embodiment shown in FIG. It has a base plate portion that is twisted so as to face inward.

That is, the core material 1 is formed by cutting a flat plate into a semicircular U-shape, and has rising portions 4 on both the left and right sides from the center portion 2 of the core material 1, and has a shape that extends up to the cut portion 5 from the center portion 2. It is to be formed.

Then, by twisting the base plate portions 3, 3 of the planar body inwardly, the base plate portions 3, 3 become shaped to face each other.

That is, a plate material is used as the core material 1, and the core material 1 is configured so as to press the surface particularly along the external shape surface of the body part.

FIG. 2 is an explanatory diagram of the second embodiment. They are almost the same in shape, and are made of a flat elastic material formed into a semicircular U-shape.Furthermore, as in the first embodiment, the substrate parts 3a, 3a extending from the rising part 4a to the cut part 5a are It is formed.

That is, the difference is that the cross-sectional shape A-A of the material is the third
As shown in the figure, it shows an unusual shape.

In FIG. 3A, one surface of the substrate portion 3a is a sloped body, and the thicker portion is denoted by 7, and the thinner portion is denoted by 8.

In addition, in FIG. B, the central portion of the substrate portion 3a has a concave shape 6, and its left and right sides have a cross-sectional shape in which one has a slightly higher thick portion 7a and the other has a slightly lower thin portion 8a.

Therefore, when such materials are used as core materials, if they are constructed so that the thicker parts are on the outside, the core materials will always fall inward toward the human body even when subjected to external pressure. It will be like that.

Such materials include elastic bodies, such as
Spring materials, stainless steel materials, etc. are preferable, and by using such materials, deformation can be effectively prevented even when external pressure is applied.

Furthermore, if a shape memory alloy is used instead of the above-mentioned material, the shape memory treatment allows the device to sense the body temperature when worn on a human body, and to form a shape that conforms to the shape of the human body.

Here, the shape memory alloy material has an alloy composition of Ni-Ti, and to explain its characteristics, when an external force is applied in the martensitic state, the deformation is completed by twin deformation, and this deformation is Since the connections between the crystals remain the same before and after an external force is applied, they return to the parent phase when heated, and the deformation strain is also eliminated.

Since the transformation point of a shape memory alloy changes depending on the composition ratio of Ti and Ni or the memory treatment temperature, it is possible to adjust the transformation point.

When deformation is applied at a temperature higher than Af, stress-induced martensite is generated, and since this stress-induced martensite is an unstable phase, it returns to the parent phase upon unloading.

Note that, similar to the shape memory effect, deformation strain is also eliminated at that time.

Furthermore, even if a stable stress-induced martensitic phase is generated under a certain stress and at a certain temperature, if it is further heated, it undergoes reverse transformation and completely returns to the parent phase by heating to the next temperature.

The stress generated at this time is much larger than the stress required to generate the stress-induced martensite, and the difference between these stresses is proportional to the difference between one temperature and the next temperature.

Thus, by utilizing the properties of the material described above, the core material of the present invention has a property that the inclination direction always inclines almost constant inward in response to external pressure, thereby preventing damage to clothing. Moreover, it is possible to obtain properties of stable adhesion.

[Effects of the invention] As will be clear from the above, the present invention uses an elastic material in a U-shape as a core material for clothing, with each of the substrate parts on both sides bent inward, so even if external pressure Even if it is subjected to external pressure, it immediately returns to its original shape and does not undergo any major deformation.Also, the base material of the core material tilts inward when exposed to external pressure, so it conforms well to the human body and is very convenient to use. .

In other words, a plate material is used as the substrate part, and the surface is pressed against the external surface of the body part, and by making the shape twist (inclined) inward of the body, The body part can be held around the body part by the plate material.

In addition, although the plate-shaped core material is bent into a semicircle and used, this shape is not specifically processed, but the semicircle is bent and tilted toward the body. It can absorb all the sizes and shapes of body parts, and at the same time it can stabilize the holding capacity, and by changing the width of the plate, it can be freely adapted to the shape of each individual body.

Furthermore, even if the garment is subjected to external pressure, the garment itself will not be damaged, which is very convenient.
