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, core materials for human clothing have been those using a round wire material in a curved shape as shown in Figure 2, and those using a semicircular board material as shown in Figure 3. 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.

However, when used in the shape of the above-mentioned material, although it has sufficient strength to some extent, it tends to deform when subjected to external pressure such as washing, etc.
In addition, in order to restore the original shape, it was necessary to manually correct the collapse.

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.

However, in the case of such technology, it is clear that processing the thin fibrous wire material to match the shape of the clothing, that is, the human body shape, and then knitting the cloth requires a significant increase in the number of man-hours and further increases the manufacturing cost.

Moreover, if the human clothing is expected to return to its shape, it must be configured to sense the human body temperature and quickly restore its shape when it comes into close contact with the human body.

[Problems to be solved by the invention] In view of the above-mentioned conventional technology, the present invention uses an elastic material or a shape memory alloy to bend a spring elastic material that can return to its shape from the center, and to bend the spring elastic material from the center to conform to the human body curve. By configuring the clothing to meet the above requirements, unexpected deformation due to external pressure can be effectively prevented, and the clothing can be maintained in a constant state of tension via the core material, thereby extending the lifespan of the clothing itself. A lengthening core material can be provided.

Furthermore, since the garment is folded inward from the center, the garment will always fall in the direction of the human body even when subjected to external pressure, thereby preventing the clothing from being damaged.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses a core material made of a flat elastic material bent into a semicircular shape.
The present invention provides a core material for clothing in which a side wall portion is formed by bending the core material so as to face each other inward from a substantially central portion thereof.

[Function] This core material is bent into a semicircular shape and folded inward, so that even if it receives external pressure, it will always fall inward toward the human body. Since it can be used in close contact with the human body at all times and without causing any abnormality, it is possible to avoid unexpected damage to clothing due to bending.

[Example] First, the present invention will be described in detail with reference to an example shown in FIG. The side wall portion 3 is formed by bending the portion 2 inward in the direction of the human body and connecting it to the cutting portions 4 on both sides.

That is, the core material 1 is formed by cutting a flat plate into a semicircular U-shape, and has side wall portions 3 on both the left and right sides from the center portion 2 of the core material 1, with a cut portion 5 rising from the side wall portions 3. It is to be formed.

Thus, by twisting the core material 1 of the planar body inward, the side wall portions 3, 3 take a shape in which they face each other.

Such a material is preferably an elastic body, such as a spring material or a stainless steel material, and by using such material, 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 temperature of the memory alloy, 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 returns to the parent phase more completely than when heated 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 the property of stable adhesion to the human body.

[Effects of the invention] As is clear from the above, the present invention is made of a U-shaped elastic material as a core material for clothing, and is bent from the center of the core material, so that the side walls on both sides are bent. Since each piece is bent inward, even if it receives external pressure, it will immediately return to its original shape and will not deform significantly, and if it is constantly subjected to external pressure, the core will tilt inward in the direction of the human body. Therefore, it is well adapted to the human body and is very convenient to use.

Furthermore, even if the garment is subjected to external pressure, the garment itself will not be damaged, so it is very effective.
