[0026] Example 1:
[0027] like Figures 1-3 As shown, this utility model provides a strapless bra, including: a bra cup 10, a back bra 20, a first support bob 30, and a second support bob 40. The bra cup 10 is constructed as two connected to each other in the width direction. The back bra 20 is constructed as two, and the two back bras 20 are respectively connected to the two sides of the two bra cups 10 away from each other. The first support bob 30 extends in the height direction and is disposed between the two bra cups 10. The second support bob 40 is constructed as two corresponding to the back bras 20, and the second support bob 40 extends in the height direction and is connected to the side of the back bra 20 close to the bra cup 10.
[0028] In some embodiments, two bra cups 10 are connected to each other in the width direction to wrap and support the breasts. Each back bra 20 is connected to the side of the corresponding bra cup 10 away from the center, and the free ends of the two back bras 20 are connected to each other to fix the strapless bra to the body and provide additional support. A first support bob 30 extends in the height direction and is disposed between the two bra cups 10. The first support bob 30 is designed to enhance the structural strength of the middle area of the two bra cups 10. Two second support bobs 40 correspond one-to-one with each back bra 20. The two second support bobs 40 extend in the height direction and are connected to the side of the back bra 20 near the bra cup 10. The second support bobs 40 are designed to increase the structural strength of the sides of the bra cup 10 and the transition area between the bra cup 10 and the back bra 20.
[0029] Understandably, the design of the first support bob 30 and the second support bob 40 is to increase the structural stability of the strapless bra when worn, so as to effectively prevent the bra cup 10 from deforming in the height direction, ensuring the shape and support performance of the bra cup 10. Moreover, the support bob can help to evenly distribute the pressure from the chest, reduce local pressure, and thus improve wearing comfort.
[0030] It is worth mentioning that the first support bob 30 and the second support bob 40 help to ensure the structural strength of the bra cup 10 in the height direction, and prevent the bra cup 10 from sinking in or turning outward due to wearing or activities (i.e., prevent the bra cup 10 from deforming in the height direction), thus ensuring the stability and aesthetics of the overall shape of the strapless bra.
[0031] According to the present invention, by setting the first supporting bob 30 and the second supporting bob 40, the structural strength of the bra cup 10 in the height direction can be improved, thereby avoiding the phenomenon of the bra cup 10 sinking inward or turning outward due to wearing or activities, and ensuring the stability and aesthetics of the overall shape of the bra.
[0032] Example 2:
[0033] Based on Embodiment 1, this embodiment further includes a bra strap 50, which extends in the width direction and is connected to two bra cups 10 and two back bras 20; wherein the top of the first support bob 30 extends to the top of the bra cup 10 and the bottom of the first support bob 30 extends to the top of the bra strap 50.
[0034] Understandably, by extending the first support bob 30 to the top of the underband 50, the entire bra cup 10 area receives stronger vertical support, effectively preventing the bra cup 10 from deforming or folding in the height direction. Moreover, the bottom of the first support bob 30 extends to the top of the underband 50, enhancing the connection strength between the bra cup 10 and the underband 50, making the bra more stable and less prone to shifting when worn.
[0035] Therefore, since the first support bob 30 extends from the top of the bra cup 10 to the top of the underband 50, the first support bob 30 provides comprehensive support for the breasts, which can significantly reduce breast movement and improve the support effect. Moreover, the design of the underband 50 allows the strapless bra to better conform to the natural curves of the body, ensuring both a good appearance and improved comfort. In particular, the combination of the first support bob 30 and the underband 50 not only increases the functionality of the strapless bra but also enhances its aesthetics, as this design can avoid wrinkles or deformation caused by insufficient support.
[0036] According to some embodiments of the present invention, the first support bob 30 is constructed as two, and the two first support bobs 30 are respectively disposed on the side of the two breast cups 10 facing each other, and the two first support bobs 30 are spaced apart from each other in the width direction.
[0037] In some embodiments, the two first support bobbins 30 are respectively disposed on the side of the two breast cups 10 facing each other, that is, in the position of the interior of each breast cup 10 near the center line. The two first support bobbins 30 are spaced apart from each other in the width direction, rather than being merged into a whole.
[0038] By placing a first support bob 30 on the inner side of each bra cup 10 (facing each other), the support in the central area of the bra cup 10 can be significantly enhanced, preventing unnecessary gaps or sagging between the bra cups 10. Moreover, the two separate first support bobs 30 help to concentrate the breasts towards the center, providing a better gathering effect, making the breasts look firmer and fuller. Of course, although the first support bobs 30 provide additional support, the two spaced first support bobs 30 still allow for a certain degree of natural bending, thereby improving the flexibility of the strapless bra and adapting to different body movements.
[0039] It is worth mentioning that the two independent first support bobbins 30 can help distribute the pressure from the chest more evenly, reduce pressure on a single point, and improve wearing comfort.
[0040] Therefore, the design of the two first support bobbins 30 provides stronger vertical support for the bra cup 10, especially in the central area, which effectively prevents the bra cup 10 from deforming or folding, enhances the stability when wearing it, and makes the wearer appear more elegant and confident.
[0041] According to some embodiments of the present invention, the underband 50 is located below the two bra cups 10, and the two ends of the underband 50 in the width direction are respectively connected to the two back bras 20; wherein the top of the second support bob 40 extends to the top of the bra cup 10, and the projection of the second support bob 40 in the width direction is at least partially located inside the underband 50.
[0042] In some embodiments, by extending the top of the second support bob 40 to the top of the bra cup 10 and ensuring that the projection of the second support bob 40 is at least partially located within the underband 50, a continuous and stable support frame is formed, which strengthens the connection between the bra cup 10, the underband 50 and the back bra 20, making the entire strapless bra more stable and less prone to displacement.
[0043] The design of the second support bob 40 not only provides vertical support, but also enhances the lateral support by intersecting the underband 50 with the projection of the second support bob 40 in the width direction. This helps to maintain the shape of the bra cup 10 and prevent the strapless bra from deforming due to activities or prolonged wear.
[0044] Therefore, the design of the second support bob 40 extending from the top to the bottom of the bra cup 10 and partially located within the underband 50 provides comprehensive support for the chest, especially during daily activities or sports. It can effectively reduce chest movement and provide better support. Moreover, the combination of the second support bob 40 and the underband 50 not only increases the functionality of the strapless bra, but also avoids wrinkles or deformation caused by insufficient support, enhancing the aesthetics of the strapless bra and making the wearer appear more elegant and confident.
[0045] Example 3:
[0046] Based on Embodiment 2, in this embodiment, a first support fabric 60 is provided on the side of the breast cup 10 near the back rib 20. The first support fabric 60 extends in the height direction, with the top of the first support fabric 60 extending to the top of the breast cup 10 and the bottom of the first support fabric 60 extending to the bottom of the underwire 50.
[0047] In some embodiments, the first support fabric 60 extends along the height direction, with the top of the first support fabric 60 extending to the top of the bra cup 10 and the bottom of the first support fabric 60 extending to the bottom of the underband 50. That is, the first support fabric 60 covers the bra cup 10 from the upper edge to the end of the underband 50 to form a longitudinal support structure.
[0048] Therefore, the main function of the first support fabric 60 is to enhance the support of the sides of the bra cup 10 in the height direction, prevent the bra cup 10 from turning over or deforming when worn, and the first support fabric 60 provides a sturdy side wall for the bra cup 10, ensuring that the chest is fully wrapped and supported.
[0049] Meanwhile, by extending the bottom of the first support fabric 60 to the bottom of the underband 50, the connection between the bra cup 10 and the underband 50 can be strengthened, making the entire strapless structure more stable. This helps to keep the bra cup 10 and the underband 50 working as a whole and improves the overall performance of the strapless bra.
[0050] According to some embodiments of the present invention, the strapless bra also includes: a second support fabric 70, which extends in the width direction and is connected to the underband 50. The top of the second support fabric 70 is connected to the bottom of the two bra cups 10 respectively, and the bottom of the second support fabric 70 extends to the bottom of the underband 50.
[0051] In some embodiments, the projection of the second support fabric 70 in the thickness direction is located inside the underband 50, and the second support portion is connected to the underband 50. Since the top of the second support fabric 70 is connected to the bottom of the two breast cups 10 respectively, and the bottom of the second support fabric 70 extends to the bottom of the underband 50, the second support fabric 70 can enhance the structural strength of the underband 50 in the height direction, thereby making the underband 50 provide better support for the two breast cups 10.
[0052] Meanwhile, since the second support extends in the width direction, the underwire 50 can provide good support for the bra cup 10 in the width direction.
[0053] It should be noted that the second support fabric 70 replaces the traditional underwire, thus avoiding the problem of the traditional underwire poking into the flesh, meaning that the strapless bra of this application can be worn more comfortably.
[0054] According to some embodiments of the present invention, the line of symmetry of the second support fabric 70 in the width direction is on the same straight line as the line of symmetry of the two breast cups 10 in the width direction. The width dimension of the second support fabric 70 is w1, and the total width dimension of the two breast cups 10 is w2, satisfying: w1 < w2.
[0055] It can be understood that by aligning the symmetry line of the second support cloth 70 with the symmetry line of the breast cup 10, it can be ensured that the overall design of the strapless bra is symmetrical left and right, which helps to provide balanced support and avoid discomfort or deformation caused by uneven force on one side.
[0056] The width of the second support cloth 70 is smaller (w1 < w2), which means that the second support cloth 70 is mainly concentrated in the central area between the breast cups 10, rather than covering the entire breast cup 10, so as to centrally provide lateral support, avoid overconstraining the chest, and at the same time maintain the necessary flexibility and comfort.
[0057] Of course, since the second support cloth 70 is located between the breast cups 10 and has a narrow width, the second support cloth 70 can more effectively disperse the pressure from the chest, reduce the compression on specific areas, and improve the wearing comfort.
[0058] It is worth noting that the second support cloth 70 is concentrated in the central area between the breast cups 10, providing strong lateral support for the strapless bra, which helps to maintain an appropriate distance between the two breast cups 10, prevent the chest from spreading or squeezing together excessively, and thus improve the overall support effect.
[0059] Preferably, the projection of the symmetry center of each breast cup 10 in the height direction on the width direction is located at the end of the second support part in the width direction.
[0060] Example 4:
[0061] Based on Example 1, this example of the strapless bra further includes: an outer garment 80, which is arranged on the side of the two breast cups 10 facing away from the human skin. The outer garment 80 is respectively connected to the back band 20 and the breast cups 10, and the projection of the breast cups 10 in the thickness direction is located inside the outer garment 80.
[0062] In some embodiments, the outer garment 80 is arranged on the side of the two breast cups 10 facing away from the human skin, that is, on the outer surfaces of the breast cups 10 and the back band 20. The outer garment 80 is respectively connected to the back band 20 and the breast cups 10 to form a complete outer covering layer. The projection of the breast cups 10 in the thickness direction is located inside the outer garment 80, that is, the breast cups 10 are completely wrapped by the outer garment 80, ensuring the neatness and beauty of the appearance of the strapless bra.
[0063] Understandably, the main function of the outer garment 80 is to provide an extra layer of coverage for the entire strapless bra, preventing the internal structure of the bra from being exposed and maintaining the simplicity and elegance of the strapless bra's appearance. Moreover, by connecting the outer garment 80 with the back bra 20 and the bra cup 10, a more integrated structure is formed, enhancing the overall stability and fit of the strapless bra. Of course, the outer garment 80 can also play a certain role in cushioning, helping to distribute the pressure from the chest more evenly, reducing direct pressure on the skin, and improving wearing comfort. At the same time, the design of the outer garment 80 can hide the internal support structure and other functional components, making the strapless bra look smoother and more beautiful, suitable for pairing with various outer garments.
[0064] According to some embodiments of the present invention, the top of the outer garment 80 protrudes from the chest cup 10, and the strapless top also includes: an anti-slip cloth 90, which is disposed on the side of the outer garment 80 facing the chest cup 10, and the anti-slip cloth 90 is also disposed on the side of the back panel 20 facing the human skin and the side panel 50 facing the human skin.
[0065] Understandably, the main function of the anti-slip fabric 90 is to increase friction and prevent the tube top from slipping or shifting during wear. By adding anti-slip fabric 90 to the inside of the outer garment 80, back panel 20, and underband 50, the entire tube top can be made to fit the body firmly, reducing the problem of shifting due to activities or prolonged wear.
[0066] Preferably, the anti-slip fabric 90 is made of a soft material with a high coefficient of friction, which allows the anti-slip fabric 90 to maintain a good feel while providing anti-slip function, reducing skin irritation and improving wearing comfort. It should be noted that traditional underband components only include the anti-slip fabric. In the strapless bra of this application, the underband component includes: the anti-slip fabric 90, the underband 50 (first layer support), and the second support fabric 70 (second layer support).
[0067] It is worth noting that the design of the top of the outer garment protruding from the bra cup 10 can visually enhance the neckline and also better conceal the upper edge of the bra cup 10, preventing the bra outline from being exposed and improving the overall aesthetics of the strapless bra.
[0068] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
