Description

Description: TECHNICAL FIELD The present invention relates to an improvement in a bra using a core material.

[Prior art] As a brassiere using a core material, Japanese Utility Model Application Laid-Open No. 54-54437
And Japanese Utility Model Application Publication No. 54-54438.

In these, a metal wire such as stainless steel is attached to the periphery of the lower half of the cup portion of the brassiere so that the fitting property and the shape holding ability can be maintained.

However, with a simple wire as in the above-described conventional example, the inclination direction of the deflection is not constant, and there is a problem in quality as a product.

[Problems to be Solved by the Invention] In view of the above conventional problems, the present invention provides a brassiere using a core material, which is fixed to the body with a constant falling direction of flexure and is comfortable to wear. It is the purpose.

Means for Solving the Problems In order to achieve the above object, according to the brassiere using the core material according to the present invention, the brassiere is mounted along the periphery of the lower half of the cup part of the brassiere, A core made of an elastic material for improving the form and attachment and mounting properties, in a cross-sectional shape perpendicular to the longitudinal direction of the core, the area above the center line CC with respect to the horizontal axis of the horizontal cross section is A. The portion below the center line C-C, which is partially semicircularly concave, is defined as B, and the B / A ratio is formed to be 0.2 or more, and the semicircular concave portion is oriented in the body direction. It is characterized by being arranged so as to face.

[Action] The area A and the deleted area B are created with respect to the center line in the horizontal axis direction, and the ratio is set to 0.2 or more, and the semicircular concave portion is arranged facing the body direction. By
Since the falling direction of the core is always limited to the outside of the cup, the commercial value of the brassiere using the core is improved.

[Example] Hereinafter, a bra using the core material according to the present invention will be described.
This will be described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of a brassier core material 10. More specifically, the brassier is attached to the lower half of the periphery of the cup portion of the brassiere, and the shape of the cup portion and super-elasticity for improving the attachment and mounting properties are shown. The core material 10 is made of a material, and in the cross-sectional shape of the core material 10, an area portion above a center line CC with respect to a horizontal axis is defined as A, and the center line C
The portion below -C, which is partially semi-circularly cut and removed, is B, and the ratio of B / A is 0.2 or more.

That is, the core material 10 is formed by extracting a long hoop material by a die drawing process, processing the hoop material into a shape as shown in the cross-sectional view of FIG. 1, and then bending the entire shape into a U-shape. At this time, it is important that the cross-sectional shape of the core material is processed into a substantially C-shape.

Note that a Ti-Ni alloy is used as the material of the superelastic material, and the memory processing is performed at a slightly lower temperature.

FIG. 1 shows a CC line at the center of the horizontal axis of the material,
The area above this is indicated as A, and the part cut below is indicated as B. Here, the part A has a curved surface on the side and the part B has been cut and removed in a semicircular shape. It is shaped like a letter.

Then, the ratio between A and B is B / A, and this value is
In order to make it 0.2 or more, first, the material having a rectangular cross section shown in FIG. 2A is diced according to FIG. 2 and the ratio becomes 0.1 when processed according to FIG. It will be 0.15.

Further, when processing is performed according to FIG. (D), the ratio becomes 0.2, and according to FIG. (E), the ratio becomes 0.25.

At this time, it is preferable to leave some portions parallel to the center line CC.

This is necessary when the material is fixed at the time of storage processing described later.

If the figures of the above description are shown in the figure, it is shown in FIG. 3, but if FIG. 4 and subsequent figures are first explained, FIG. 4 shows the brassier core material 10 when pressures P and P are applied from both sides. ,
Naturally, it bends inward.

When this bending is viewed from the side, when it is bent outward as shown by the arrow of the cup portion 11 of the bra as shown in FIG. 5, it becomes a defective product due to its appearance, and FIG. When the flexure is bent inward as shown by the arrow of the cup portion, the body is pressed, and the product is good.

In order to obtain a good product, that is, to bend inward as shown in FIG. 6, a ratio of 0.2 or more is required as shown in FIG. 3, which is shown in FIG. The above processing is required. That is, in the figure, the one with a ratio of 0.1 is bent inward by 60%,
In the case of 0.15, 90% is inside, but in the case of 0.2 or more, 100% is bent inward as shown in FIG. 6 to guarantee the quality as a product.

Accordingly, the cross-sectional shape is made into a C-shape as shown in FIG. 2 and the ratio of B / A is reduced by processing having a curved surface as shown in FIG.
By setting it to 0.2 or more, the quality of the core part 10 of the cup part 11 of the brassiere is guaranteed.

When attaching to the cup part 11 of the bra,
The mounting direction is such that the direction 10a of the convex portion of the C shape is the outer direction of the cup portion 11.

As a result, the bending direction is inward and a fixed direction is guaranteed.

[Effects of the Invention] As described above, according to the present invention, even when external pressure is applied to all products, the cup peripheral edge of the brassiere using the core material is bent inward of the cup portion, that is, toward the body. As a result, it is possible to provide a bra that is in close contact with the body more effectively and that is comfortable to wear.

Furthermore, if a core material formed so as to leave a portion parallel to the center line on the outer periphery of the cross-sectional shape is used, the work becomes easier when the core material is attached to the cup portion and sewn, and the core material is used. The bra sewing operation is efficient.
