BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support wire for a bust cup portion used to support a chest to maintain a shape as a support wire for a bust cup portion such as women's underwear or sports clothing.

Conventionally, a shape preserving core for saving the breast is used in various ways depending on the use, function, and strength of the garment having a bust cup such as a bra, a brush slip, a body suit, a leotard, a swimsuit, and the like. The preservation core needs the following characteristics.

① Be able to prevent the wearer's chest from flowing down the armpit. ② put the skin and fat pushed to the armpits inside the cup to make the breasts look bigger. ③ The lower circumference of the bust cup is widened under the force when worn, so that the height of the upper part of the cup should not be lowered. ④ Deform appropriately in response to the stretching of clothing by the change of body surface when moving the body. ⑤ To be able to withstand fatigue fracture by repeated bending stress during washing. ⑥ It needs points that should not be rusted by chemicals (bleach) and salt caused by washing or sweating.

The shape preserving core material which satisfies the above requirements is a method of covering the entire breast of the wearer with a resin molded cup such as foamed urethane and the like, and a thin synthetic resin core formed in the shape of a bow or a thin steel wire or a shape memory alloy wire. There is a method for mounting to the bent portion of the lower edge of the bust cup portion, and recently, the support wire for processing the steel wire having a rectangular cross section to be mounted to the lower bend portion of the bust cup portion is used most recently.

However, the method of covering the whole chest with the former urethane resin molding cup was originally developed in a product that reinforces the cup part by sewing and has been used in the past as a seamless cup because it eliminates the stitching mark on the cup part.

However, this urethane mold product is so flexible that its shape holding power of the chest is weak, the resin molding cup is thick, and the foam urethane is used for the material, so the durability of the bleach is insufficient, and the breathability is not used well. There is a case where a preservative material obtained by forming a mesh-shaped thin sheet material into a cup shape is used in a female swimsuit.

And the synthetic resin core formed in the shape of a bow is non-metallic and can be designed freely in the shape of the cross section, so its application is wide. However, compared with the metal core, it is supported by expensive molding molds as well as lack of elasticity and strength. It is uneconomical because the cost is high because the bow shape and the developed size of the wire are required. In addition, the saving of the mold cost has a problem in that the underwear design is not limited because the number of shapes and sizes cannot be made. The support wire, which is a curved shape of the shape memory alloy wire, is sold as a soft wire that is soft and less deformed due to the superelastic effect of the alloy and low modulus of elasticity. , The material is expensive, there is a problem that takes too much cost and time for heat treatment (molding process).

The support wire, which is made of steel wire with a rectangular cross section and is bent in a bow shape, can be mass-produced at a low cost, is excellent in maintaining shape of the chest, and can withstand the burden of repeated washings. It has a balanced characteristic as the most widely used.

Since the backing wire is primarily intended to maintain and correct the shape of the wearer's chest, technical orientations exist in the wire material, cross-sectional shape, and dimensions.

In other words, if only the purpose of maintaining and correcting the shape of the chest, a material with a high elasticity may be used, but a material with a high elasticity has a large feeling of contact with the skin at the same time, and the shape retention effect and the good feeling of wearing have the opposite elements.

In order to solve this problem, the cross-sectional structure of the supporting wire is rectangular, and it is smooth for stress (thinness and vertical direction) against skin (thin core is easy to bend), and strong for horizontal stress with skin (deeper width than thickness). There is a support wire that has been studied, and a wire that has been studied in a three-dimensional shape that bends both ends and the bottom of the wire away from the fat side to alleviate the feeling of the wearer touching the flesh.

On the other hand, the most important function expected of the supporting wire is that the bow-shaped both ends do not open to the left or right even when worn on the bra and the like.

Brasers are configured to stretch over the entire length of the bras and to wrap tightly around the wearer's chest.

However, when the cup portion is intensively stretched, both ends of the supporting wire open a lot, and as a result, the peak height of the bust cup is lowered, thereby deteriorating the shape of the bust portion of the wearer by deteriorating the shape of the front portion of the most important bra.

In order to prevent the two end portions from being pulled to the side by the force at the time of wearing, the width of the wire may be widened, the thickness of the wire may be thickened, or the elasticity (elastic modulus) may be considered. Increasing the modulus of elasticity does not occur even when the bow is pulled sideways by the force at the time of wearing, but at the same time, when the three-dimensional shape of the wearer and the wire contacting portion do not coincide with each other, the pressing force of the wearer may be increased at the same time, which may worsen the feeling of wearing.

In other words, since the effect of the cross-sectional dimension width of the wire appears in proportion to the adaptation force to the skin (vertical and vertical direction), it is natural from the viewpoint of material mechanics. There is a limit to improving to satisfy the characteristic.

On the other hand, it is well known among the relevant companies that improvement for the purpose of improving the comfort of the supporting wire does not require provision of measures for the overall length of the wire. That is, the strong contact between the backing wire and the wearer's skin is at both ends of the wire in the longitudinal direction.

As a solution to this problem, for example, the support wire disclosed in Japanese Patent Application Laid-Open No. 3-19804 may be a three-dimensional curved surface, and both ends may be separated from the skin, or the aggregate for the prosthetic core material disclosed in Japanese Patent Application Laid-Open No. 2-132605 may be used. It is proposed to reduce the elasticity by making the aggregate width narrower in the width of both end portions than the width near the center portion of the lower curved portion.

However, the former three-dimensional curved support wire is too difficult to form and process the curved surface, it takes a lot of time to manufacture, it was difficult to narrow the width of both ends even in the case of the latter prosthetic core aggregate.

The present invention has been researched and developed in order to solve the above problems, improves the shape of the breast holding force when wearing a bra to gather the breasts more beautifully, by lowering the pressure felt on the skin, very comfortable to wear cup cup support wire It is for the purpose of providing.

In order to solve the above problems and achieve the object, the present invention is a bow-shaped support wire according to the lower curved portion of the bust cup portion, the support wire is integrally overlapping a plurality of steel wires, the cross-sectional area of the plurality of wires The support wire of the bust cup part which is configured to give strength and partial elasticity by the total difference of was developed and adopted.

Moreover, in this support wire of the bust cup part comprised as mentioned above, the support wire of the bust cup part which a some wire is a combination of a heterogeneous material wire was developed and adopted.

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

1 is a bow shape along the lower curved part of a bust cup part, and is a cross section rectangular support wire which consists of a metal wire with elasticity.

Metal wires include steel, stainless steel or nickel titanium alloys, nickel titanium chromium alloys and other shape memory alloys, superelastic materials, titanium as light materials, duralumin, and the like, but the material is not limited to achieve the object of the present invention.

The supporting wire 1 has a long overall length having an inner arch portion 1a, a lower arch portion 1b, and an outer arch portion 1c having a portion along an inner edge, a lower edge, and an outer edge of the bust. The same bending rate as the lower arch 1b described above is made by shortening the supporting wire 1A and the inner arched portion 11a and the outer arched portion 11c along the outer edge and outer edge than the long supporting wire 1A. The short length support wire 1B which consists of the lower arc part 11b of this is overlapped in the thickness direction, and is comprised.

The lower arcuate portion 1b having a large thickness having a large cross-sectional area where the long supporting wire 1A and the short supporting wire 1B overlap, has increased elasticity, and the inner arching shape 1a and the outer arching shape of only the long supporting wire 1A. (1b) has a small cross-sectional area and a thin thickness, resulting in weak elasticity.

The long supporting wire 1A and the short supporting wire 1B may be made of a material such as steel wire or steel wire, or may be a double material such as a shape memory alloy wire and a stainless steel wire of nickel titanium alloy. Combinations are not limited to those described above. In some cases, the thickness may be the same or different.

The strong elastic part is not limited to the lower arch 1b above, for example, it may be an arcuate part connected to one edge of the lower arc part 1b, and conversely, the weaker elastic part may be both an arch part or one side. It may be an arch.

Numeral 2 denotes a metal connection such as a small short metal tube of spring back or a metal buckle having an opening, which overlaps the long supporting wire 1A and the short supporting wire 1B, and has a predetermined distance from both ends of the long supporting wire 1A. It is provided in the lower position, the both ends of the short support wire 1B are pinched | interposed, and it is integrally mounted.

Reference numeral 3 denotes a resin film layer that has arrived on the outer circumferential surface of the integrated support wire 1 so that the wires of the two layers are integrated so that they are not easily separated even by the deformation occurring during washing, thereby eliminating the difference in appearance. It looks like a stand wire.

Numeral 4 denotes a urethane resin cap which is fitted to both ends of the supporting wire 1, and when the urethane resin cap 4 is used, the front end portion of the metal connecting member 2 in which the supporting wires 1A and 1B are stacked As far as the front, the boundary between the two-ply and one-ply and the one-ply of both edges do not cause breakage, fracture or extreme bending under external pressure.

According to the embodiment of the present invention configured as described above, the use state is described together with the effects and effects. The support wire 1 is inserted into and fixed in the loop tape sealed according to the lower curvature of the bust cup part such as bra.

When wearing this bra, the thickness of the bow-shaped lower arched portion 1b is so thick that the elasticity is strong, so that even if the force is applied to both sides of the supporting wire 1 in an enlarged and reduced direction, the breast does not stretch or shrink well. It can be prevented from being pushed toward the armpit, and it is excellent in bust formation and shaping as well as bust up. In addition, the outer edge is less elastic than the lower arch portion, and lowered the pressure to touch the skin, so that the side close to the side smoothly fit is good.

Example 1

Hereinafter, specific embodiments of the present invention will be described.

Long steel support wire having a thickness of 0.4 mm and a width of 2 mm provided with an inner arch 1a, a lower arch 1b, and an outer arch 1c along the curved portion of the bust cup. 1A) Insert a metal contact body 2 made of steel with a small thickness of 0.18 mm and a length of 2.0 mm at a position of about 25 mm from the inner upper edge and about 30 mm of the outer upper edge, and the metal of the steel Both ends of the support wire 1B made of steel with the inner arched portion 1a and the outer arched form 1c shortened to the contact bodies 2 and 2, and the long steel support wire 1A and the short steel The supporting wire 1B was bonded and the supporting wire 1 was obtained.

That is, a portion of about 25 mm from the inner top edge and about 30 mm from the outer top edge is made of one layer of steel support wire 1A only, and the remaining portion of the steel support wires 1A and 1B is formed. It is doubled. This integrally formed steel support wire 1 was heated to remove the work stress, and the coating layer 3 having a thickness of 0.2 mm was arrived with a nylon resin to be treated as a single wire by eliminating defects in appearance.

Example 2

A superelastic support made of a long nickel titanium alloy having a thickness of 0.4 mm and a width of 2 mm in which the inner arched portion 11a, the lower arched portion 11b, and the outer arched portion 11c are curved in a curved shape along the curved portion of the bust cup portion. Non-magnetic stainless steel connection body 12 (12 mm) having a thickness of 0.18 mm and a length of 2.5 mm with a small spring back at a position of about 33 mm from the inner top edge of the wire 11A and a position of about 40 mm from the outer top edge. ), And both ends of the support wire 11B made of stainless steel having the inner arched portion 11a and the outer arched portion 11c shortened to the non-magnetic stainless steel connecting members 12 and 12. Tighten, the superelastic support wire 11A which consists of a long nickel titanium alloy, and the support wire 11B made of short stainless steel were bonded together, and the support wire 11 was obtained.

That is, a portion of about 33 mm from the inner top edge and about 40 mm from the outer top edge is made of only one layer of superelastic support wire 11A that is flexible and hardly deformed, and the remaining portion is made of superelastic support wire 11A and elasticity. This strong stainless steel support wire 11B is doubled. After heating and processing the supporting wire 11 of the integrated composite material, the film layer 13 having a thickness of 0.2 mm is arrived by nylon resin after the stress is removed. It was.

The support wire 11 configured as described above is used for bust cups such as bras, and the support wire 11 has the softness of the shape memory alloy and the superelastic wire, and the texture of touching the skin is improved, and the prosthesis of the chest does not open. And excellent at molding, beautiful bust silhouette was obtained.

In addition, the steel support wires 1 and 11 described above may be used by covering the urethane resin caps 4 and 4 at both ends, as shown in FIG. 7 in some cases. Even if external pressure is applied to the boundary part and one layer of both ends, it can prevent extreme bending, breakage, or breakage, so it can be used for a long time.

As described above, since the entire support wire is made of the same material, it is necessary to cope with a change in the cross-sectional area and cross-sectional shape of a single wire to partially change its elasticity. However, in the present invention, since the cross-sectional area of the plurality of wires due to the overlapping of the same material is different, the elastic pressure is partially lowered to exert the shape retention effect of the support wire to provide a soft wearing feeling.

In addition, the combination of the dual materials allows to obtain various elasticities that are soft and less deformable than conventionally achieved, and can be widely used as various supporting wires.
