1. Technical Field
The utility model relates to the field of women's underwear, in particular to a three-dimensional bra underwire.
2. Description of Related Art
In order to get better body shape, the lower edge of the cup of the existing bra, shape wear and other women's underwear is lined with the semi-circular underwire. Most of the existing underwires are made by bending the banded metal strip into the semi-circular one. However, the planar underwire cannot be consistent with the hemispherical cup, so the exertion of the functions of the underwire is influenced, which means the underwire has bad supporting effects. What's more, traces of the underwire tend to be left on the body of the uses who wear the bra, influencing the comfort when wearing.
The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a three-dimensional bra underwire which is matched with the cup shape well, has good supporting effects and is comfortable to use.
In order to solve the aforementioned technical problem, the technical solution adopted by the utility model is as follows:
A three-dimensional bra underwire comprises the middle part and two ends of the underwire, wherein the middle part of the underwire is the inclined section with a certain inclination angle, while at least one end thereof is the flat section, and the inclined section is connected with the flat section by a transition section. The transition section has a twist angle which is continually changed from the joint with the flat section. The inclination angle is defined as the included angle between the horizontal and vertical surface of the underwire when used, which is the same with the definition of the twist angle. Due to the design of the inclined section and the transition section of which inclination angle is gradually changed, the shape of the underwire is matched with the human body curves well and the contact area between the underwire and the human body is larger so that the better supporting effects can be achieved and it is comfortable to wear and not easy for the traces of the underwire to be left on the human body. In addition, the inclination angle of the transition section which is gradually changed makes a smooth connection between the inclined and flat section, which means that there is no bulge in the underwire which is easy to make you fell uncomfortable; Meanwhile, due to the structure of smooth transition, it is difficult to produce stress concentration, which can greatly reduce the possibility of fracture at the connected position. In the utility model, with the transitional design from the inclined plane to the flat plane, the traditional flat underwire is changed into a three-dimensional underwire with a certain torsional stress so as to ensure that the underwire is matched with the cup shape well; The utility model has been formed integrally and is easy to be manufacture.
Preferably, two ends of the underwire are the flat sections. The symmetrical design of the underwire makes better structural performance. The underwire is not easy to be deformed.
The inclination angle of the inclined section can be 15 to 85 degrees. Based on the requirements of different users generally, the range of the inclination angle of the inclined section preferably is from 20 to 75 degrees. If the user's bust is small, the smaller inclination angle is more appropriate, that is, 30 to 40 degrees are generally taken; if the user' s bust is big, the bigger inclination angle is more appropriate, that is, 60 to 75 degrees are generally taken.
For the size of most users, the inclination angle of the inclined section is preferably 38±4 or 26±6 degrees.
In order to ensure that the two ends of the underwire are difficult to prick the pocket at the lower edge of the cup so as to prolong the service life of the underwear and increase wearing comfort, the end of the underwire is matched with the protective paint layer, epoxy resin layer or polyurethane layer, or covered by nylon layer or thermoplastic elastomer.
In order to further enhance the structural safety of the underwire and increase using comfort, the end of the flat section can further be covered by at least one layer of thermoplastic sleeve made from polyethylene.
The wire constituting the three-dimensional bra underwire can be stainless steel, high carbon steel, titanium metal wire, resin plastics or polyester plastics.
Compared with the prior art, the beneficial effects of the technical solution of the utility model are as follows: due to the design of the inclined section and the transition section of which twist angle is gradually changed, the traditional flat underwire is changed into a three-dimensional underwire with a certain torsional stress so as to ensure that the underwire is matched with the cup shape and has good supporting effects, bringing the shaping functions of the underwire into full play. Meanwhile, due to the better fit between the underwire and the human body, traces of the underwire can not be left on the body of the users, improving the wearing comfort.
