Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a core material attached along the lower edge of a cup of a brassiere worn on the human body.

[Conventional technology]

Conventionally, the core material of brassieres has been a round wire made of stainless steel, as shown in Figure 5.
It is generally curved in the shape of a letter and is used by being attached to a predetermined lower edge of the cup.

Furthermore, in JP-A No. 50-95050, the core material is
It consists of an elongated shape with a flattened cross section over almost the entire length of the lower edge of the cup part,
A technique is disclosed in which the flattened core material is twisted from its flattening plane to conform to the contour of the breast.

In any case, wire rods are used to shape the outline of the breasts with the cup of the brassiere, and as mentioned above, curved wire rods of the same shape are used.

[The problem that the idea aims to solve]

However, such conventional brassiere core materials are made of round wire material that conforms to the contours of the breasts, or are processed into a flat shape and are attached to the core material, so it is difficult to adjust due to the weight and movement of the breasts. As a result, the cup is susceptible to pressure, which increases the degree of deformation, and due to the pressure, the shape of the cup is not always able to maintain its initial intended contour.

Such cores have been shown to be effective in other materials, such as plastics, but depending on the size of the cup, they are subject to additional resistance, and therefore may not be able to support the cores if they are made of the same shape. I found something that wasn't there.

Under such conditions, the core material becomes particularly susceptible to deformation when subjected to external pressure such as washing, and such a core material is not necessarily good.

For this reason, as disclosed in Japanese Patent Application Laid-Open No. 61-63701, plastic is used as the core material, and the arc-shaped part is connected to the base part 12 at the center position (the part directly below the breast on one side). , the middle part 1 of both ends
4, 15 and further end portions 16, 1 at both ends thereof.
7, the cross-sectional shape of the base portion 12 is made larger than the intermediate portions 14, 15, and the intermediate portion 14,
A brassiere core material in which the cross-sectional shape of the core material 15 is larger than that of the end portions 16 and 17 has been proposed.

In this conventional example, due to creep characteristics, the end portion 1
6 and 17 are pulled together, and the original arc shape is opened outward.

However, when such a core material is applied to a bra, the end portion 16 or 17 is located at the innermost part between the breasts (the center of the breast) where no deformation is necessary, and the rigidity of this portion is the lowest as described above.
When worn, the core material as a whole spreads from side to side, resulting in a problem in that the shape-retaining effect at the center of the chest, which is required for a brassiere core material, is reduced.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention is attached to the lower edge of the cup part of a brassiere worn on the human body, and is attached along the shape of the lower edge.
The core material is made of an elastic material, and the core material has maximum rigidity by locating the maximum thickness or width at the lower edge of the cup portion, which corresponds to the innermost part between both breasts. The invention is characterized in that the rigidity is reduced by decreasing the plate thickness or plate width toward the outside of the breast.

[Effect]

By providing such a bra core material,
The inner side of the breast, which is subject to relatively large pressure but does not require deformation, retains its cup shape with a predetermined rigidity, while the outer side of the breast, which is subjected to relatively low pressure and requires deformation to match the shape of the breast, has a low rigidity. With this structure, the cup core material can effectively and reliably deform or maintain the shape required of the brassiere core material depending on the location and pressure.

Further, the core material itself may be easily manufactured by changing the thickness of the material in the length direction or changing the width of the material in the length direction.

Furthermore, if the core material is molded from a shape memory alloy, by memorizing its curved shape, a predetermined memorized temperature is sensed, and the shape and rigidity that suit the cup are always maintained. .

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a core material 1 used in a brassiere A according to a first embodiment of the present invention, and FIG. 2 shows a core material 2 according to a second embodiment.

The core material 1 has a uniform thickness 1a and is cut from stainless steel, for example, and has a cross-sectional shape 1.
The width dimension of b is longer than the cross-sectional shape 1c on the opposite side.

And, as mentioned above, the plate thickness is constant, but
The width thereof gradually narrows in the length direction and reaches the cross-sectional shape 1c. Therefore, even if it is curved, the narrow portion in one direction is likely to bend. That is, the rigidity is large near the cross-sectional portion 1b, while the rigidity becomes weaker as it moves closer to the cross-sectional portion 1c.

Further, according to the core material 2 shown in FIG. 2, the thickness 2a gradually becomes thinner toward one cross-sectional shape 2c, but the width of the core material 2a becomes thinner in the direction of the cross-sectional shape 2c.
The width is the same between the two.

Therefore, according to the core material 2, the stiffness is higher near the thick portion 2b of the cross-sectional shape.

The core material 1 or 2 is installed in a storage section at a predetermined location on the lower edge C of the cup B of the brassiere A shown in FIG. At this time, the core materials 1 and 2 are attached so that the more rigid parts, that is, the cross-sectional shapes 1b and 2b, are located inward in the storage part of the lower edge C, that is, in the center of the chest.

In this way, the core material 1 or 2 maintains its shape due to its rigidity so as to maintain the contour of the cup part B, and the inner side of the breast, which is subjected to relatively large pressure but does not need to be deformed, retains the cup shape due to its predetermined rigidity. The outer part of the breast that needs to be deformed according to the shape of the breast has a relatively weak pressure, so the core material for the cup has a weak rigidity. The deformation region required for the brassiere core material can effectively and reliably maintain its shape.

Note that FIG. 4 is a diagram for explaining the shape of the core material according to an embodiment other than that described above, that is, A is a diagram in which the width of the core material 3 suddenly becomes narrower from the portion 3a. This provides a difference in rigidity.

FIG. B also shows a difference in rigidity due to a change in plate width, and one side is narrower in the portion 4a.

Figure C shows changes in plate thickness, with the plate thickness suddenly becoming thinner at portion 5a.

In addition, Figure D shows an attempt to obtain a difference in rigidity by bonding plates of the same thickness to only one end.

In any case, a difference in rigidity is obtained by providing a difference in thickness in the width region of the plate in the length direction of the core material.

By using the core material as described above in the lower edge C of the cup part B, there is no abnormal feeling when the brassiere A is worn on the human body, and the product can be made to have a better feel.

The core material was described as an elastic material, for example, a spring material such as stainless steel, but this material may be made of Ni-
It is even more effective if it is formed into a shape memory alloy made of Ti.

When a core material made of such a material is worn as the core material of Brassiere A, the core material senses the human body's body temperature and returns to its shape by adapting to the shape of the human body, always maintaining the contour of the cup part. hold it.

Here, to explain the characteristics of the Ni-Ti alloy composition of the shape memory alloy material mentioned above, when external force is applied in the martensitic state, deformation is completed by twin deformation, and this deformation is caused by the application of external force. Since the connections between the crystals are maintained the same before and after the ivy, when heated, they return to the parent phase, and at that time 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.

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.

[Effect of idea]

The present invention having the above configuration can achieve the following effects.

(1) The inner part of the breast, which does not need to be deformed, maintains its cup shape with a predetermined rigidity, and the outer part of the breast has a weaker rigidity, so it can be deformed vertically to match the shape of the breast, and It is possible to effectively and reliably maintain the deformation or shape retention required of the brassier core material according to pressure and pressure.
Even when worn on the human body, the device can be used with a good feel without causing any abnormal sensations.

(2) When the core material is molded from a shape memory alloy material and worn, the core material senses the human body's body temperature, adjusts to the shape of the human body, returns to its shape, and always maintains the contour of the cup. can be maintained in the same state.
