Description

TECHNICAL FIELD

[0001] The utility model relates to the underwear field especially a steel ring connecting structure for steel ring underwear. BACKGROUND

[0002] With the development of the times, the Chinese underwear market develops from only steel ring bra to no steel ring bra, camisole, halter, breast patch and different subcategory underwear. Despite this, the steel ring bra maintains the mainstream market share by virtue of its good fixing, supporting and chest shaping capacity. Especially for people with larger breasts, the steel ring underwear can better meet their needs of support and fixation. However, the steel ring bra has a big disadvantage that the key stress point suture will rub the flesh and be uncomfortable. This is because the main manufacturing process of the steel ring underwear is splicing, so that the shoulder straps, cups, steel rings, side ratios and back ratios are spliced to form a complete underwear. The splicing of the general steel ring bra on the market usually adopts the form of "overlapping splicing", for example, the steel ring sleeve is directly sewn inside the cup, so that the two ends of the steel ring sleeve directly overlap and are superimposed on the fabric, and the joint stitches, resulting in thickening and flesh rubbing at this place, greatly reducing the comfort experience. To this end, the utility model provides a steel ring connecting structure for steel ring underwear to solve the above problems. SUMMARY

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1 This utility model embodiment provides an underwire connection structure for an underwire bra. The underwire bra includes: a cup 10, a side panel 20, an underwire 30, an underwire connection structure 40, and shoulder straps 50. The underwire connection structure 40 includes a first edging 410, a second edging 420, a third edging 430, and an underwire sleeve 440. The underwire sleeve 440 is located at the connection between the cup 10 and the side panel 20, and is connected to both the cup 10 and the side panel 20. The underwire sleeve 440 is used to wrap around the underwire 30, thereby fixing the underwire 30. The two ends of the shoulder strap 50 are connected to the cup 10 and the side panel 20, respectively. The first edging 410 is located between the two ends of the shoulder strap 50, and the first edging 410 is located at the edge of the connection between the side panel 20 and the cup 10, wrapping one end of the underwire sleeve 440 while also wrapping the edge of the side panel 20 and the cup 10, as shown at point a in Figure 1. The second edging 420 is located at the upper edge of the two cups 10 and wraps around the two cups 10 and the other end of the underwire sleeve 440 located between the two cups, as shown at point b in Figure 1. The third edging 430 is located at the lower edge of the side back bra 20 and wraps around the lowest point of the underwire sleeve 440 and the lower edge of the side back bra 20, as shown at point c in Figure 1. The first edging 410, the second edging 420, and the third edging 430 all edge the edges of the underwire bra, thus enclosing the underwire bra. The two ends and the lowest point of the underwire sleeve 440 are respectively embedded in the first edging 410, the second edging 420, and the third edging 430, thereby fixing the underwire 30 and further smoothing and naturally addressing the stress points of the underwire 30.

[0022] See Figures 2-4The first edging 410 has its two sides folded inward to form a double fold. One end of the underwire 440 is embedded in the center of the first edging. The seam where the outer end of the underwire 30 meets the bend is an important fixing and support point on the outside of the underwire bra. As the underwire 30 stretches and contracts with the body, it will rub severely against the armpit area, making it a point of strong stress. However, most underwire bras on the market simply overlap the outer end of the underwire with the bend and sew it together. When the fabric is layered and thickened, it increases friction and discomfort. The first edging 410 folds its two sides inward to form a double fold, and then inserts the outer end of the underwire 30 into the double-fold structure of the first edging 410 to create an embedded effect. This makes the seam smooth and rounded, greatly reducing roughness and discomfort from the bra rubbing against the armpit area. This results in a comfortable and natural wearing experience for the underwire bra.

[0023] The other end of the underwire sleeve 440 is located between the two cups 10. The two sides of the second edging 420 are folded inwards to form a double fold. The other end of the underwire sleeve 440 is embedded in the center of the second edging 420. The second edging 420 extends from between the two cups 10 to the edges of the two cups 10, uniformly wrapping the upper edges of the two cups 10. Due to the force of the underwire 30, users with large breasts are extremely prone to poking the inner end of the underwire 30 at the center gore. Simultaneously, the inner end of the underwire 30 is also prone to friction with the inner skin of the breast, making it a point of strong stress. In contrast, most commercially available underwire bras simply overlap and sew the inner end of the underwire to the bra cup fabric at the center gore. This results in the underwire sleeve and cup fabric being overlapped and sewn together, making this area thicker and rougher, causing chafing. The second edging 420 first uses double-layered folded fabric to finish the upper edge of the cup 10. Before sewing, the inner end of the underwire 30 is inserted between the double-layered folded fabric to create an embedded effect. This greatly reduces the roughness of the joint at the inner end of the underwire 30, reducing the discomfort of the bra's center gore poking or chafing. This results in a comfortable and natural wearing experience for the underwire bra.

[0024] The third edging 430 has a Y-shaped cross-section. The lowest point of the underwire 440 is inserted into the middle of the Y-shaped structure, so that the underwire 440 is embedded in the center of the third edging 430. The common practice for underwire bras on the market is to overlap and sew elastic bandages, boning, and cup fabric together, which not only increases thickness and causes chafing, but also creates a stiff seam under the cups, compressing the body and increasing discomfort. The third edging 430, through its Y-shaped structure, "inserts" the underwire 440, boning, and cup fabric into the middle of the Y, forming a seamless, rounded wrap, eliminating the need for seams and reducing discomfort from chafing. This results in a comfortable and natural wearing experience for the underwire bra.

[0025] In this embodiment, the connection structure at the other end of the steel ring sleeve 440 is the same as the connection structure at one end of the steel ring sleeve 440. The connection structure at the lowest point of the steel ring sleeve 440 is also the same as the connection structure at one end of the steel ring sleeve 440. However, in other embodiments, the connection structure at the other end of the steel ring sleeve 440 may differ from the connection structure at one end of the steel ring sleeve 440. The connection structure at the lowest point of the steel ring sleeve 440 may also differ from the connection structure at one end of the steel ring sleeve 440.

[0026] In summary, this embodiment of the invention optimizes the connection structure between the underwire and the underwire bra. Specifically, it optimizes the connection structure at the three stress points of the underwire bra, folding the first and second edgings inwards to form a double-layer fold. The two ends of the underwire sleeve are embedded in the center of the first and second edgings, respectively, resulting in a smooth and natural fit at the stress points of the underwire bra. Furthermore, the third edging 430 has a Y-shaped cross-section, with the lowest point of the underwire sleeve 440 inserted into the middle of this Y-shape. This achieves a seamless, rounded fit around the three stress points of the underwire bra, reducing chafing. By embedding the underwire sleeve into the first, second, and third edgings, the stress points of the underwire are fully engaged, further reducing chafing and improving the comfort of wearing the underwire bra.

[0027] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the utility model.
