Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a wire bone for cup shape retention in bras, swimwear, etc.

(Prior Art) Conventional wire bones for cup shape retention used in bras, swimsuits, etc. are as shown in FIGS. 4 and 5.
It is formed from a semicircular core wire made of elastic metal or hard synthetic resin that curves along the lower edge of the bust cup, and its cross-sectional shape is a flat rectangular shape with front and back surfaces parallel to the vertical plane. It was hot.

(Problems to be Solved by the Invention) However, with such conventional wire bones, it was not possible to distinguish between the front and back sides when sewing them to the cup. For this reason, it is necessary to check whether the fabric will bend in the direction of contact with the body or in the opposite direction when sewing, which has the drawback of requiring a large amount of time.

In addition, there is a problem that it is easy to twist and deform, and when worn, it does not fit the body and digs into the skin, causing a feeling of pressure and damage.

This invention eliminates the above-mentioned problems, and allows you to distinguish between the front and back at a glance, fits well to the bulge of the bust, provides a natural wearing condition that does not feel uncomfortable, and is sturdy. This provides a strong wire bone for retaining the shape of a cup such as a bra.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a wire bone made of an elastic metal material curved in a semicircular shape to match the lower end of the bust cup. The cross-sectional shape in the width direction between the outer peripheral edges is an elongated rectangular shape with the same width from top to bottom, and an arcuate shape that bulges forward over the entire length, and the wire bone is covered with a synthetic resin coating layer, and this arcuate shape It is sewn to the lower edge of the bust cup with the convex arcuate surface facing outward and the concave arcuate back surface facing the body.

(Embodiment of the invention) Below, the drawings showing the embodiments of the invention will be explained. 1 is a wire bone main body made of an elastic metal wire curved in a semicircular shape along the lower edge of the bust cup. , this wire bone main body 1 has a cross-sectional shape in the width direction between the inner peripheral edge 1a and the outer peripheral edge 1b in a vertically elongated rectangular shape with the same width from the upper end to the lower end, and has a convex arc-shaped surface 2 that bulges forward over the entire length.
and a concave arc-shaped back surface 3. 4 is a coating layer coated with a synthetic resin liquid applied to the entire surface, and 4a and 4b are colored parts with different colors painted on both ends. This is for position confirmation.

The wire bone main body 1 constructed in this way is sewn from the lower edge of the cup portion 6 of the brassiere 5 to both side edges, with the convex arcuate surface 2 facing outward and the concave arcuate back surface 3 facing the side that contacts the body. It is inserted into the bag section 7 that is provided.

(Effect of the invention) The present invention has a cross-sectional shape in the width direction between the inner circumferential edge 1a and the outer circumferential edge 1b of the wire bone 1, which has an elongated rectangular shape with the same width from top to bottom, and an arcuate shape that bulges forward over the entire length. Since it is formed into a shape, the front and back sides can be seen at a glance, eliminating the troublesome operation of checking the front and back sides as in the past. This saves time and allows for efficient production, as well as increasing the strength of the wire bone 1 in the direction of expansion and contraction, and preventing twisting. It does not deform and does not break or dig into the skin when worn, causing a feeling of pressure or damage.It also does not deform due to bending and is strong and strong.

Furthermore, since the surface of the wire bone 1 is coated with a synthetic resin coating layer 4, it will not rust even if it is washed or comes into contact with sweat, and can be used for a long period of time.

In addition, since the convex arc-shaped surface 2 is made on the outside and the concave arc-shaped back surface 3 is made on the body side, when the wire bone main body 1 is biased in a direction to expand or contract, both ends are always on the back side with respect to the center part. It has the effect of bending and deforming, conforming to the bulge of the body, and has high bending elasticity, so even when the arm moves up and down, it responds immediately to the movement, and does not put pressure on the bust, and fits perfectly to the body, making it feel strange. This means that you can wear bras etc. without any problems.

Claims (1)

[Scope of utility model registration request] In a wire bone made of an elastic metal material that is curved in a semicircular shape to fit the lower end of the bust cup, the cross-sectional shape in the width direction between the inner peripheral edge 1a and the outer peripheral edge 1b of the wire bone main body 1 has the same width from the top to the bottom. The wire bone 1 is formed into an elongated rectangular shape and an arcuate shape that bulges forward over the entire length, and the wire bone 1 is covered with a synthetic resin coating layer 4, and the convex arcuate surface 2 of the arcuate shape is outwardly shaped into a concave arcuate shape. A wire bone for retaining the shape of a bust cup, such as a bra, characterized in that the back side 3 is sewn to the lower edge of the bust cup with the back side 3 facing the body.
