DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breast cup having a breast cup, a body suit, a fit slip, a leotard and the like, and a garment such as a swimsuit. The present invention relates to a breast cup shape retaining bone used for adjusting the shape.

Heretofore, as a breast cup retaining bone of this type, an elastic wire having a round cross-section or a flat cross-section has been basically bent into a semicircle. When this is actually incorporated into the cup part of the garment and worn, the lower side of the breast is pressed by this bone, and the center of the breast and the armpit are cut into the ends of the bone, or the narrow side of the bone The side is bitten, and the feeling of wearing and the shape retention of the breast are not always sufficient.

[0003] Conventionally, in order to improve such a feeling of wearing and breast shape retention, for example, a substantially central portion of a semicircular portion viewed from the upper side with the side in contact with the body inward is referred to as a reference surface. The middle part from the center bottom to both ends is a plane that matches the reference plane, and the part from these planes to both ends is outside the reference plane again. (See Japanese Utility Model Publication No. 59-5683 and Japanese Utility Model Application Laid-Open No. 6-39).
No. 909, etc.), the outer edge arc-shaped portion, the lower edge arc-shaped portion, and the inner edge arc-shaped portion are substantially planar, and the inner side faces outward from the inner lower edge toward the inner upper edge. There has been proposed one having an inclined surface on the inner surface side formed on an inclined surface rising in the direction (Japanese Patent Publication No. 4-47042).

However, when any of the above breasts for holding a breast cup is placed on a plane and viewed from above, there is no twist from one end to the other end, and the wide surface of the elastic wire has substantially the same width. It has a continuous shape, and when it is incorporated into the cup part of the garment and worn, one end of the bone is pulled toward the axillary side, so that both ends of the semicircular bone are pulled away and expanded, As a result, particularly when the elastic wire used has a flat cross-sectional shape, a strong restoring force is generated based on the elastic deformation of the bone.

[0005] For this reason, especially when the breast moves during walking or exercise and the pulling force of the clothing on the axillary side acts on or does not act on the bone, the restoring force based on the elastic deformation of the bone each time. May or may not work, and as a result, the axillary end of the bone or a part thereof may partially penetrate into the axillary area, particularly for a long time such as walking or exercising. When doing this, the axillary part where the bone hits may be painful, and the wearing feeling may be extremely impaired.

Further, the conventional breast cup retaining bone is placed on a flat surface, and the central bottom portion, the body center side standing portion and the axillary side standing portion are placed on a flat surface in such a manner as to be freely movable in the horizontal direction from above. Pressing it upwards and making this bone almost flat, the flat basic shape obtained is almost a semicircular shape. For this reason, when a predetermined curved shape is given to this bone, the lower side of the breast is supported to form the breast shape The width of the central bottom portion becomes smaller than necessary, and the fit when worn is impaired.

[0007]

The inventors of the present invention have made intensive studies to solve such a problem, and as a result, in the case of a bone having a flat cross section, the center bottom located at the lower side of the breast and the center of the breast body have been described. Not only does the body-side standing part located on the side and the axillary standing part located on the breast underarm side bend in the direction away from the plane, but the armpit-side standing part is based on the approximate center of the center bottom. In the range of 45 to 90 °, the twist is given in the direction in which the front faces outward, and at the time of wearing, the underarm standing portion is preferentially elastically deformed and expanded based on the twist shape. As a result, the axillary side of the bone is placed on the axillary side of the body over a substantially wide area over substantially the entire length of the bone, thereby allowing the axillary side of the bone to move even when the breast moves due to walking or exercise. Part of the armpit or part of the armpit Without such bites, it found that a very good wear feeling and breast shape retaining property can be obtained, and have completed the present invention.

[0008] Therefore, an object of the present invention is to prevent the end of a bone or a part of the bone from coming into contact with a part of the bone, particularly in the lower armpit, so that the bone can be worn for a long time by being incorporated into clothing and moving around. Another object of the present invention is to provide a breast cup shape retaining bone which provides excellent wearing feeling and breast shape retaining properties.

[0009]

That is, according to the present invention, an elastic wire having a flat cross section is formed, and the elastic wire is curved into a substantially lower edge shape of the breast cup so that the wide surface side is the front face G. It is a breast for shape retention of a breast cup which was formed by making the center bottom part (B
D) and the body center side standing part (between AB) located on the breast body center side and the axillary side standing part (between DEF) located on the breast underarm side are curved in a direction away from the plane. And at least the underarm standing portion (between DEF) is 45 to 90 ° from its starting point (point D) to its tip (point F) based on the approximate center (point C) of the central bottom.
Has a twisted shape in which the front face G is turned outward in the range of. When wearing, the armpit-side standing portion (between DEF) is based on the twisting shape and the body-centered standing portion (A to B) (Between) These elastically deformed parts and the body center side upright end (point A)
A breast cup shape retaining bone that expands in a predetermined range between the front end of the armpit and the front end of the armpit (point F).

In the present invention, the elastic wire material for forming the bone may have a flat cross section having a wide surface and a narrow surface. For example, the elastic wire may have a rectangular cross section or an elliptical cross section. Is also good. Further, the material of the elastic wire forming the bone is not particularly limited, for example, even if it is made of metal such as a shape memory alloy,
It may be made of synthetic resin such as ordinary resin or shape memory resin rich in elasticity, or may be a composite material in which a resin is integrally molded around a shape memory alloy as a core material. A shape memory alloy, a composite material using this shape memory material as a core material, and the like are preferable because they are maintained for a long time.

[0011] The one-bone bone of the present invention preferably has a substantially vertical semi-elliptical shape in which the upper half thereof is cut along a substantially shorter diameter when the body is not worn, and is elastically deformed when the body is worn. It is expanded and its front shape becomes a substantially semicircular shape, and more preferably, when not dressed, when dressed, the body center side standing tip and the axillary standing tip in the front shape. It is preferable that the gap be expanded in the range of 0.3 to 6 cm. As a result, the one-yabone is provided with a moderate elasticity due to its moderate elasticity. As well as having a good foot on the body as if sandwiched between them, it has excellent breast shape retention.

In the present invention, the underarm standing portion of the bone has a substantially semicircular front surface within a range of 45 to 90 ° from the starting point to the tip with respect to the substantially center of the central bottom of the bone. The twisted shape twisted in the outward direction is preferably applied from the approximate center of the central bottom to the start of the axillary standing part.
It has a twisted shape that is continuously twisted in the range of 0 ° or less and in the range of 45 ° to 90 ° from the starting point to the tip of the axillary standing part. When one end of the bone is pulled to the axillary side and the ends of the semicircular bone are pulled apart and expanded, the axillary standing part is preferentially elastically deformed based on the torsion shape. And the axillary side upright fits the axillary of the body on its wide surface over almost its entire length,
As a result, the elastic wire having a flat cross section is not gently elastically deformed to generate a strong restoring force, and
Even when the breast moves due to walking, exercise, or the like, the bone is elastically deformed and follows the bone well, so that the end of the bone or a part thereof does not partially come into contact with and bite.

Here, the degree of torsion in the torsion shape of the underarm standing portion is 45 degrees with respect to the approximate center of the central bottom of the bone.
If the angle is less than 90 °, the strong restoring force based on the cross-sectional flat shape of the elastic wire material cannot be sufficiently relaxed when worn, and the feeling of wearing may be impaired.On the contrary, if the degree of twist exceeds 90 °, the surface shape of the human body The shape will be opposite, and the fit will be worse. Similarly, when the twist is applied more than 40 ° from the approximate center of the center bottom to the starting point of the axillary standing part, the fit is deteriorated.

Then, the bone of the present invention is placed on a plane, and the center bottom, the body center side standing part and the axillary side standing part are pressed from above onto the plane in a freely movable state in the horizontal direction. The flat basic shape obtained by making the curved shape and the torsion shape of the bone substantially flat is a flat substantially ship bottom shape having the center bottom portion as the ship bottom portion, and the bone or its extension line at the time of wearing is the chest circumference of the body. A substantially semi-elliptical locus shape having a major axis substantially coincident with a direction connecting two points intersecting the line, and the above-described curved shape and twisted shape are given thereto, and the entire shape is substantially semi-circular or substantially semi-circular. It has a substantially vertically semi-elliptical shape with the upper half cut off along the minor axis. In addition, whether or not the chest line of the body intersects the bone when dressed depends on the length of the bone.If the length of the bone is short and the chest line does not directly intersect the bone, one of the bones or Imagine two points that intersect the chest line when both distal ends are extended.

[0015] Here, the flat basic shape of bones that forms the substantially semi-elliptical trajectory shape, preferably the ratio of its major axis (D _L) and minor axis _{(D S) (D L /} D S) is 1.1 It is better to be in the range of ~ 1.5, so that when one end of the bone is pulled to the armpit and spread when worn in the cup part of the garment, it follows the shape of the human body well. As a result, the entire bone fits almost evenly on the lower half of the breast, creating an excellent wearing feeling.

When the bone of the present invention is formed of, for example, a synthetic resin, a curved shape and a torsion shape may be simultaneously provided together with a necessary basic shape. For example, an elastic wire made of a shape memory alloy may be formed of gold. It may be set in a mold and subjected to a heat treatment for imparting a curved shape and a torsion shape under predetermined heating and pressurization, and further formed by heating the elastic wire rod into a shape substantially equal to its flat basic shape. It may be formed by giving a predetermined curved shape and a twisted shape below, or may be formed by punching and pressing from a flat plate material. As a result, at least the curved shape and the twisted shape are given to a predetermined degree. It should just be done.

It should be noted that the breast for retaining a breast cup of the present invention is not limited to a type which is separately applied to each of the left and right sides of the breast, but is provided between the left and right breasts while maintaining the basic shape described above. In addition, it may be formed in a continuous W shape, or may be formed in an inverted U shape in order to be applied to clothing such as a bare top bra.
