Description

Technical Field

[0001] The utility model relates to the technical field of bras, in particular to a three-dimensional flexible support structure with a shaping function and a bra. Background Art

[0002] Existing bra support structures primarily utilize rigid underwires, soft plastics, or adhesive strips, secured to the underside of the cups or at designated locations. These structures maintain the shape of the bra and shape the breasts after wear. However, the fixed shape of the support structure prevents it from adapting to breast movement, preventing it from maintaining a consistent fit and hindering wearer comfort.

[0003] CN109619710A discloses a single-head, automatically adjustable bra underwire, comprising a first and second curved body. The first body is made of stainless steel, while the second body is made of a memory alloy. Separating the first and second bodies allows the first body to play a supporting role, supporting the bra's lower body and fitting it to the chest, while the second body provides support and shaping, maintaining a straight and upright chest, ensuring a more comfortable fit. However, the supporting structure and bra can cause a sense of pressure on the chest, causing discomfort to the wearer. Utility Model Content

[0004] In view of this, the present invention aims to propose a three-dimensional flexible support structure and a bra with a shaping function, which can reduce the pressure of the support structure on the chest and improve wearing comfort.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A three-dimensional flexible support structure with a shaping function, wherein the end closest to the middle of the bra is the inner end, and the end away from the middle of the bra is the outer end. A flat section is provided between the inner and outer ends. The inner end is smoothly connected to the flat section at point M, and the outer end is smoothly connected to the flat section at point N, so that the support structure is arc-shaped as a whole. The inner end rotates around point M to form an inclination angle α, and the outer end rotates around point N to form an inclination angle β. The straight line length of the arc of the entire support structure is C, the straight line length of the arc of the inner end is m, and the straight line length of the arc of the outer end is n, where m = (C ÷ 3) × e and n = (C ÷ 2) × f, where e and f are both compensation coefficients, e = 0.8 to 1.2 and f = 0.8 to 1.2. Through this design, the inner and outer ends form a deflected section away from the chest, reducing the pressure of the support structure on the chest and improving wearing comfort. The inner and outer ends are further twisted at a specific length, ensuring that the support structure provides good support for the chest while allowing the chest to have a certain amount of space for movement, thereby alleviating the feeling of oppression on the chest.

[0007] Furthermore, the support structure includes an upper structural member and a lower structural member, the ends of which are connected by an intermediate connecting layer, and a gap is formed between the upper and lower structural members, so that the support structure can be easily bent and deformed, and can move relative to the chest in response to movement.

[0008] Furthermore, the inclination angle α is 40-65°, and the inclination angle β is 40-65°. The inclination angle α cooperates with the linear length m of the arc at the inner end, and the inclination angle β cooperates with the linear length n of the arc at the outer end. While ensuring the strength and support effect of the support structure, the two ends of the support structure are offset from the chest, creating space for the chest to move, preventing pressure marks on the wearer after wearing, and providing good support and shaping effects even during strenuous activities.

[0009] Furthermore, the thickness of the gap is t = 0.01-1 mm. If t is too small, the upper and lower structural members are not easily separated. When the two layers are combined, the support structure cannot form a three-dimensional structure to support the chest, and it is difficult to deform accordingly with the chest. If t is too large, the bra can easily be pinched between the upper and lower structural members, which is not conducive to comfort.

[0010] Furthermore, the upper and lower structural members have the same shape and structure, with a cross-sectional width a of 3 to 8 mm and a cross-sectional thickness b of 0.2 to 1 mm. By limiting the size of the upper and lower structural members, the support structure is ensured to have a certain strength to stably support the chest while also being able to deform with the chest, improving wearer comfort.

[0011] Furthermore, the intermediate connection layer is any one of a welding layer and an adhesive layer, and the ends of the upper structure and the lower structure are connected together by welding or adhesive.

[0012] Furthermore, the thickness T of the intermediate connection layer is 0.01-0.5 mm, which is used to ensure a stable connection between the upper structural member and the lower structural member while preventing the thickness of the intermediate connection layer from being too thick and affecting the aesthetics.

[0013] Furthermore, protective layers are provided on both the inner end and the outer end to reduce the wear on the chest caused by the sharp end of the supporting structure, thereby better protecting the wearer.

[0014] Compared with the prior art, the three-dimensional flexible support structure with shaping function described in the present invention has the following advantages:

[0015] (1) The inner and outer ends are formed into an oblique section away from the chest, reducing the pressure of the support structure on the chest and improving wearing comfort. The inner and outer ends are further twisted at a specific length, ensuring that the support structure provides good support for the chest while allowing the chest to have a certain amount of space for movement, thereby alleviating the pressure on the chest.

[0016] (2) The upper and lower structural parts are not completely connected, but have a gap in the middle, which makes the support structure easy to bend and deform, and can move relative to the chest with the movement of the chest, so as to better fit the chest, shape the chest and support it.

[0017] Another aspect of the present invention provides a bra comprising the above-mentioned three-dimensional flexible support structure with a shaping function. The bra and the above-mentioned three-dimensional flexible support structure with a shaping function have the same advantages over the prior art, which will not be repeated here.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. The embodiments described in the present invention are exemplary and intended to be used to explain the present invention, and should not be understood as limiting the present invention.

[0030] It should be noted that the terms "upper," "lower," "left," "right," "front," and "rear" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The embodiments of the present invention and the features therein may be combined unless otherwise specified.

[0031] like Figures 1 to 6 As shown, a three-dimensional flexible support structure with a shaping function, the end close to the middle of the bra is the inner end 5, the end away from the middle of the bra is the outer end 6, a flat section 7 is set between the inner end 5 and the outer end 6, the inner end 5 is smoothly connected to the flat section 7 at point M, and the outer end 6 is smoothly connected to the flat section 7 at point N, so that the support structure is arc-shaped as a whole, the inner end 5 rotates with point M as the rotation point to form an inclination angle α, and the outer end 6 rotates with point N as the rotation point to form an inclination angle β, the straight line length of the overall arc of the support structure is C, the straight line length of the arc of the inner end 5 is m, and the straight line length of the arc of the outer end 6 is n, m = (C ÷ 3) × e, n = (C ÷ 2) × f, wherein e and f are compensation coefficients, e = 0.8 ~ 1.2, and f = 0.8 ~ 1.2.

[0032] This design creates an angled section between the inner and outer ends 5 and 6, which deviates from the chest. This reduces the pressure exerted by the support structure on the chest and improves wearing comfort. Furthermore, the inner and outer ends 5 and 6 are twisted to a specific length, ensuring that the support structure provides adequate support for the chest while allowing the chest room to move, alleviating the pressure. If m and n are too large, excessive angled sections will form, hindering the support structure's ability to provide adequate support and gather the chest. If m and n are too small, not only will this cause discomfort, but it will also affect the smooth transitions between the inner end 5 and the flat section 7, and between the outer end 6 and the flat section 7, resulting in abrupt and uneven transitions. The sharp edges of these transitions can cause the wearer to experience a sharp, foreign object sensation, making the chest feel like it's being cut.

[0033] It should be noted that point M is the endpoint of the inner end 5 away from the middle of the bra, and point N is the endpoint of the outer end 6 toward the middle of the bra.

[0034] The inclination angle α and the inclination angle β are designed according to the wearer's chest shape, making the bra design more ergonomic. Specifically, the inclination angle α = 40 ~ 65°, and the inclination angle β = 40 ~ 65°. The inclination angle α and the arc-expanded straight-line length m of the inner end 5 cooperate with each other, and the inclination angle β and the arc-expanded straight-line length n of the outer end 6 cooperate with each other. Under the premise of ensuring the strength and support effect of the support structure, the two ends of the support structure are deviated from the chest, forming a space for the chest to move, preventing marks on the wearer after wearing, and providing good support and shaping effects even if the wearer engages in strenuous activities. Under normal circumstances, if the chest is relatively large, the corresponding inclination angle α and inclination angle β are also relatively large, and if the chest is relatively small, the corresponding inclination angle α and inclination angle β are also relatively small.

[0035] As a preferred example of the present invention, Figures 2-4As shown, the support structure comprises an upper structural member 1 and a lower structural member 2, connected at both ends by an intermediate connecting layer 3, with a gap between them. The intermediate connecting layer 3 serves to connect the upper and lower structural members 1 and 2, but the two are not completely connected; instead, a gap exists between them, allowing the support structure to bend and deform easily and move relative to the chest. In the prior art, support structures typically consist of only one layer, providing a certain level of strength. This makes it difficult to deform with chest movement and thus fails to shape the breasts. Designing the support structure as two layers with a gap between them ensures strength while creating a three-dimensional structure that is easily deformed under external forces. When the wearer's chest position changes due to movement, the support structure adapts accordingly, better fitting to the chest, shaping, and supporting it. The ends of the upper and lower structural members 1 and 2 are flattened in cross-section to ensure better fit and are connected via the intermediate connecting layer 3.

[0036] In order to make the support structure deform better with the chest, the upper structure 1 and the lower structure 2 are made of flexible materials, such as flexible steel.

[0037] The thickness of the gap is t = 0.01 to 1 mm. If t is too small, the upper structural member 1 and the lower structural member 2 will not easily separate, and when the two layers are together, the supporting structure will not be able to form a three-dimensional structure to support the chest, and it will not be easy to deform accordingly with the chest. If t is too large, the bra will easily be clamped between the upper structural member 1 and the lower structural member 2, which is not conducive to comfort. Because the inner end 5 and the outer end 6 are curved sections, the flat section 7 has no torsional inclination, and the chest will continuously change position with the wearer's movements. The t of each part of the gap can be equal or unequal to better match the changes in the chest and allow the wearer to move freely.

[0038] Furthermore, the upper structural member 1 and the lower structural member 2 have the same shape and structure, and the upper structural member 1 is taken as an example for detailed description. The cross-sectional width a of the upper structural member 1 is 3 to 8 mm, and the cross-sectional thickness b is 0.2 to 1 mm. By limiting the size of the upper structural member 1 and the lower structural member 2, it is ensured that the support structure has a certain strength to stably support the chest, while being able to deform with the chest to improve wearing comfort. Since there is a gap between the upper structural member 1 and the lower structural member 2, and both are made of flexible materials and have deflected ends, the upper structural member 1 and the lower structural member 2 of the utility model can be exactly the same, and can change with the changes in the chest to fit the chest and better set off and shape it. There is no need to set the two structural members to be different, nor is there any need to make the angles between the upper structural member 1 and the lower structural member 2 different.

[0039] Furthermore, the intermediate connecting layer 3 is either a welding layer or an adhesive layer, which connects the ends of the upper structural member 1 and the lower structural member 2 by welding or adhesive bonding. At the same time, it is important to avoid overflow of welding or adhesive material, which could affect the aesthetics of the support structure. The intermediate connecting layer 3 has a thickness T of 0.01 to 0.5 mm, ensuring a stable connection between the upper structural member 1 and the lower structural member 2 while preventing excessive thickness that could affect the aesthetics.

[0040] In order to prevent the end of the support structure from pricking the chest, the inner end 5 and the outer end 6 are both provided with a protective layer 4 to reduce the wear of the chest caused by the sharp end of the support structure, which can better protect the wearer. Figures 7-8 As shown. Furthermore, the protective layer 4 is a coating applied to the outside of the inner end portion 5 and the outer end portion 6, or a protective sheath provided on the outside of the inner end portion 5 and the outer end portion 6. The length S of the protective layer 4 is ≥ L+2, where L is the length of the intermediate connecting layer 3. That is, the protective layer 4 covers the intermediate connecting layer 3 and is used to conceal the intermediate connecting layer 3.

[0041] The present invention also provides a bra that uses the above-mentioned three-dimensional flexible support structure with a shaping function. The bra also includes conventional bra components such as cups and shoulder straps, and the three-dimensional flexible support structure with a shaping function is arranged at the bottom of the cups.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
