Description

[Detailed Description of the Invention] Industrial Application Field This invention can respond to changes in breasts over time during pregnancy, and is suitable for changes in breast expansion and enlargement even though the bra has a built-in cup wire. The present invention relates to a wire brassiere that is particularly suitable for use before childbirth.

Conventional technology In conventional bras for pregnant women, the cup portion that covers both the left and right breasts is mostly made of non-stretchable material, so from the early stages of pregnancy There is a defect in the inability to accept changes in breast expansion and expansion over time (changes in breast expansion in the height direction and expansion changes in the direction of the base of the breast) that appear during the pregnancy period leading up to childbirth. It was hot.

Various types of bras have also been proposed in which the cup portion is made of stretchable material, but this naturally has a limit to its allowable range;
During the month, breast volume increases compared to before pregnancy.
Around the 7th month of pregnancy, the bra cup size according to the JIS size standard typically increases by more than 2 cup sizes, and by the 5th month of pregnancy, not only the height of the breast but also the base area, which is the base area, gradually increases. The system was subject to extensive changes and did not have the functionality to adequately respond to these significant changes.

In order to accommodate such changes in the surface of the chest body, that is, the breasts, it is required to purchase brassieres of at least different sizes, and attention has been focused on brasiers that correspond to the degree of expansion and expansion of the breasts.

The main purpose of the cup part of a brassiere is to stabilize the breast itself, as well as to provide compensation and modeling functions. Wire bras, which have semicircularly curved cup wires made of hard metal or synthetic resin along the curved part, are intended to hold the breasts themselves in a fixed manner, so it is important to In comparison, it is not possible to make the cup itself follow the changes over time in the breasts of pregnant women, which undergo significant changes, and no bra has been developed to make them follow such changes.

Conventional metal cup wires with a rectangular or circular cross section are made of a single piece of spring steel. A force is generated that shows resistance and tries to forcefully return to the original shape, and even if it corresponds to a certain breast size, it does not follow the changes in breast expansion and enlargement over time at all. .

Therefore, unless the cup wire always matches at least the base of the breast, which is the base area of the breast,
This is directly linked to inhibiting the growth of the mammary glands due to compression of the breasts, making it impossible to obtain breasts with naturally developed mammary glands. Furthermore, since conventional cup wires are made of a single wire, the load (the weight of the breast)
On the other hand, the load is concentrated on the lowest part of the breast,
There was a defect in the wire that caused cracks and damage.

In addition, instead of this metal cup wire, a cup wire made of synthetic resin material,
Although it is relatively flexible and bendable compared to metal cup wires, it cannot follow the expansion of the base of the breast over time, and when it follows this expansion, the wire becomes a wire. It doesn't hold, and it just becomes a distorted shape.

Problems to be Solved However, the prenatal wire brassiere according to the present invention was developed as a result of intensive research in view of the defects of the conventional wire braziers mentioned above. In addition to eliminating various defects,
A wire bra for prenatal use that can track and respond to changes in the breasts during pregnancy, where the degree of breast expansion and the area of the base increases over time, from pregnancy to childbirth, and which has significantly improved breast support ability. The aim is to provide

Further, to provide a wire bra for prenatal use that follows the changes in the breasts due to pregnancy, gives appropriate tension to the breasts without unnaturally compressing them, promotes natural growth of the breast lines, and prevents breast drooping. It is an object.

Furthermore, even though the brassiere uses a planar cup wire with a circular cross section, it will fit flexibly according to the curvature of the thoracic body surface, resulting in cracks and damage to the wire. The purpose of the present invention is to provide a prenatal wire brassiere that does not cause damage to the cup part.

Means for Solving the Problems In order to achieve the above-mentioned object, in the prenatal wire brassiere of the present invention, the left and right cup portions 1 are elasticated with their respective elasticity in the direction of the nipple. The outer fitting part 2 has a lower edge curved part 7.
From the front center line 6 of the brassiere A, the shoulder strap 5 is constricted inward toward the base and curved into a crescent shape. The upper filling piece 4 has a wedge-shaped shape extending from the upper end of the front center line 6 toward the base of the shoulder strap 5, and the lower edge curved portion 7 of the cup portion 1 has a boat-shaped shape extending to the middle of the cup portion 1. Along the core wire 8, a plurality of wire-shaped thin wires 9 are arranged closely around the outer periphery of the core wire 8, and a cup wire 10 is provided along the core wire 8, each of which is wound so as to form a spiral shape. There is. Next, specific examples of the prenatal wire brassiere according to the present invention will be described in detail.

A is a wire bra for prenatal use according to the present invention, and the wire bra A includes a cup part 1 made of an elastic material that covers and receives both the left and right breasts, and a cup part 1 located on the side of the cup part 1. The elastic bag cloth 13 extends from the body part and is applied along the side and back side of the body, and the shoulder straps 5 are installed from the upper tip of the cup part 1 to the bag cloth 13. It is prepared.

The cup part 1 is made by sewing together three component parts into a three-dimensional so-called cup shape. The material is made to have great stretch in the direction of the nipple.

Reference numeral 2 denotes an outer filling piece that comes into contact with the vicinity of the center of the lower edge of the breast 14, as well as on the outer and side surfaces of the breast 14;
The outer fitting piece 2 curves inward from a position close to the front center line 6 at the lower edge curved part 7 of the cup part 1 toward the base of the shoulder strap 5, forming a constricted crescent shape. We are prepared. One end of the stretchable bag cloth 13 is sewn to a portion located on the side of the outer filler piece 2.

3 is near the center of the lower edge of the breast 14 and the front center line 6
From the middle of the front center line 6 of brazier A,
Breast 14 extending halfway through outer filling piece 2
It is a lower fitting piece that is brought into contact with the surface of the lower half of the holder, and has a boat-like shape.

4 is an upper fitting piece that extends from the upper end of the front center line 6 of the bra A in the direction of the base of the shoulder strap 5 and comes into contact with the upper half of the breast 14;
It has a wedge-like shape.

Thus, the three component parts forming the cup part 1 touch each other at the inner edge of the outer fitting part 2, the outer edges of the lower fitting part 3 and the upper fitting part 4, and the lower fitting part 3. The upper edge and the lower edge of the upper filler piece 4 are sewn together to produce the cup portion 1. Reference numeral 10 denotes a semicircular cup wire attached along the lower edge curved portion 7 of the cup portion 1 constructed in this manner.

Such a cup wire 10 is not manufactured from a single metal spring body as in conventional products, but is made by assembling a relatively large number of wire rods and integrating them into a semicircular shape. It is made of wire.

That is, the cup wire 10 used in the present invention is obtained by using the core wire 8 made of steel and having a circular cross-sectional shape and the thin wire 9. At this time, the core wire 8 forming the core of the cup wire 10 is Along the outer periphery of the cup wire 10, a plurality of wire-shaped thin wires 9 forming the outer body of the cup wire 10 are closely aligned, and each of the thin wires 9 is aligned so as to form a spiral shape. The semicircular spring body 11, which is wound and tightened, is a cup in which the core wire 8, each of the thin wires 9, and the adjacent thin wires 9 are evenly and closely curved, as shown in FIG. The wire will be what you get.

Specifically, a core wire 8, which is a wire-like steel material having a circular cross section with a diameter of 0.6 mm, is used, and a thin wire 9 of the same material with the same diameter as the core wire 8 is placed around the outer periphery of the core wire 8.
As shown in Fig. 4, six wires are used and arranged in a row, and each of the thin wires 9 is tightly wound into a spiral shape, and a semicircular shape with a predetermined length and a diameter of 1.8 mm is formed. The spring body 11 is bent.

Basically, this spring body 11 is made by carrying the cup wire 10 into a mold having a substantially semicircular shape with one end slightly longer, and then heat-treating it by baking to form the shape according to the mold. A precipitation fixing method is adopted in which the material is fixed to a bent cup wire 10 to produce a so-called spring steel.

Then, a coating layer 12 is formed using a synthetic resin solution on the entire surface of the cup wire 10, which is made by winding the fine wire 9 spirally around the outer periphery of the core wire 1. It is possible to obtain an anti-corrosion effect and an effect of preventing damage to the fabric at the curved lower edge of a cup such as a brassiere due to the smoothing of the spiral surface. The wire-shaped steel used in the present invention can be produced by appropriately selecting a wire with a diameter of 0.3 to 0.8 mm to produce a cup wire with a desired elasticity value. In addition to the case where the core wire 8 and the thin wire 9 are made to have the same diameter, when the core wire 8 is made larger in diameter than the thin wire 9, the diameter of the core wire 8 in this case is within the above range. By increasing the diameter without stopping, the suppleness and bendability of the cup wire 10 in all directions is weakened, and it becomes a hard type when in use, but it can follow any expansion of the base area of the breast 14 without distortion. It is possible to achieve the effect of easily and reliably following the curvature of the thoracic body surface.

Moreover, it is of course possible to practice the present invention by using a wire rod made of a material having higher rigidity than the thin wire 9 for the core wire 8.

Effects of the Invention According to the prenatal wire bra of the present invention,
The three pieces constituting the cup part 1, that is, the outer fitting part 2, the lower fitting part 3, and the upper fitting part 4, are arranged so that their elasticity increases in the direction of the nipple. Because the sutures are integrated, as the breast 14 expands and expands over time from pregnancy to childbirth, elastic properties appear radially starting from the nipple, and this results in the ability to follow the remarkable changes in the breast 14. Become.

That is, the expansion change in the height direction a of the breast 14 is as follows:
Since the elasticity of each part increases toward the nipple, no pressure is applied to the height of the breast, including the nipple, and when the breast 14 expands in the direction b, At least the portion located on the side of the outer filling piece 2 located at the side can be expanded freely, so that the expansion change can be smoothly followed.

Similarly, the lower fitting piece 3 and the upper fitting piece 4, which have large elastic properties in the direction of the nipple, each
It exhibits a degree of expansion and contraction that corresponds to the change in the size of the breast 14, and always fits smoothly to the breast 14, but at this time,
Since the outer fitting piece 2 is formed so as to constrict inwardly from near the front center line 6 of the lower edge curved portion 7 toward the base of the shoulder strap 5 and curve into a crescent shape, the lower edge curved portion 7 of the cup portion 1 Since the elasticity in the direction from the shoulder strap 5 to the shoulder strap 5 is small, a moderate feeling of tightness can be imparted to the breasts 14, which tend to sag due to the increased weight due to significant breast tension, and a bust-up effect can be exerted. I can do it.

A cup wire 10 is attached to the curved lower edge 7 of the cup portion 1 that follows such expansion and expansion changes of the breast 14.
The cup wire 10 is designed to prevent the breast 14 from sagging by always maintaining the brassiere A in a well-aligned position. Wind the spring body 1 into a shape.
Therefore, the thin wires 9 surrounding the outer periphery of the core wire 8 are formed in close contact with each other but independently of each other.
The cup wire 10 exhibits flexibility and flexibility in all directions, and even though it is made into a spring, a flexible cup wire 10 that is flexible and elastic can be obtained.

The cup wire 10 itself responds to significant changes in the expansion and expansion of the breast during pregnancy, that is, changes in the dimensional expansion of the breast 14 in the base direction b and changes in breast weight including the height direction a of the breast 14. Since the cup wire 10 changes according to this and always expands in the same shape as the base of the breast 14, it is possible to handle the expansion and expansion changes of the breast 14 with a single wire, and the breast 14 becomes larger and heavier. Conventional cup wires, which aim to provide comfortable support and fixed support for the breast 14, inevitably compress the mammary glands and inhibit their growth. It has the effect of encouraging

By aligning the plurality of thin wires 9 and winding them in a spiral, a flexible deformation region is created even against external force in the lateral direction, which is the direction c-d in FIG.
It also has spring-like elasticity, so it can perform its original function as a wire even though it is flexible.

In addition, since each of the thin wires 9 is twisted together in a spiral shape, the load is buffered and distributed between adjacent thin wires 9, and the critical point where the wire deforms is greatly reduced. For this reason, the wire can be expected to undergo elastic deformation, and a state in which the wire is unlikely to crack or be damaged due to load can be obtained.

Conventional cup wires have an expansion effect only at both ends, but the wire used in the present invention disperses force at any position, providing an elastic and free expansion effect, so that the breast is always expanded. We can expect a follow-up expansion.

Since the wire has elastic and flexible deformation, the wire conforms to the curvature of the chest body surface, preventing local pressure, digging, and skin abrasion, and ensuring that the wire remains the same even as the breast changes over time. It becomes a cup wire that feels worn.

Furthermore, by making the thin wires 9 have the same diameter, the wires become more circular, and the wires do not lose their shape in the converged state, resulting in a well-balanced shape.

In this way, the structure of the cup portion 1 and the structure of the cup wire work together to produce effects that cannot be achieved with conventional brassieres of this type.
