Description

Technical Field

[0001] This application relates to the field of underwear technology, specifically to a structurally reinforced pair of underwear. Background Technology

[0002] As residents' living standards continue to improve, the intimate apparel market is experiencing a wave of consumption upgrading. Consumers' demands for underwear are no longer limited to basic coverage; they are now focusing more on comfort, fit, and functionality. However, traditional underwear has many design flaws that fail to meet consumers' growing experiential needs.

[0003] From an ergonomic perspective, traditional underwear generally uses a straight-line stitching design on the sides, which makes it difficult to conform to the natural curves of the abdomen. For consumers with more abdominal fat, the overly tight waistband seams can easily leave marks, causing discomfort and a "waist-binding" effect, leading to fabric bunching and affecting the appearance. For pregnant women, as the abdomen grows, the straight waistband design cannot adapt to the changing body shape, causing pressure to concentrate on the lower back, exacerbating symptoms such as lower back pain. At the same time, gaps can easily form between the abdomen and the underwear, making it easy for the underwear to shift or bunch up during activities, affecting the wearing experience. Utility Model Content

[0004] In view of the above problems, this application provides a structurally reinforced underwear that solves the problem that existing underwear cannot fit the abdominal curve, resulting in marks and gaps.

[0005] To achieve the above objectives, the inventor provides a structurally reinforced pair of underwear, comprising a front body, a back body, and a crotch area. The corresponding sides of the front body and the back body overlap and connect at the abdomen to form a first overlapping portion and a second overlapping portion, so that the front body and the back body form an abdominal circumference. The two sides of the crotch area and the lower side of the abdominal circumference form two first openings for the legs to pass through. The first overlapping portion and the second overlapping portion extend upward from the crotch area in a V-shape to both sides.

[0006] Furthermore, the included angle between the first overlapping portion and the second overlapping portion ranges from 30° to 45°.

[0007] Furthermore, the first overlapping portion and the second overlapping portion overlap at one end of the crotch area to form a third overlapping portion.

[0008] Furthermore, a third suture line is provided on the third overlapping part, and the third suture line connects the first overlapping part, the second overlapping part, and the front of the underwear.

[0009] Furthermore, the corresponding sides of the front and back of the underwear overlap on the human abdomen and are connected by a first suture and a second suture, respectively. The first suture is located at the first overlapping part, and the second suture is located at the second overlapping part. The first suture and the second suture form a V-shape.

[0010] Furthermore, the first suture and the second suture are located on opposite sides of the first overlapping portion and the second overlapping portion.

[0011] Furthermore, the first suture line and the second suture line are parallel to the corresponding edges of the first overlapping portion and the second overlapping portion.

[0012] Furthermore, it also includes an elastic band, which is sewn to the top edge of the front and back of the underwear after being placed on the corresponding sides of the front and back of the underwear at the abdomen.

[0013] Furthermore, it also includes elastic linings, two of which are respectively connected to the first opening, and the width of the elastic linings gradually decreases from the back of the underwear to the front of the underwear.

[0014] Unlike existing technologies, the above-mentioned technical solution features an overlay and a back panel of underwear where the corresponding sides overlap at the abdomen to form a first overlapping portion and a second overlapping portion. The first and second overlapping portions extend upwards from the crotch towards both sides to form a V-shaped structure. The V-shaped structure design, taking advantage of the fabric's elasticity, can dynamically adjust with changes in waist circumference, precisely conforming to the natural curves from the waist to the abdomen (such as waist depressions and abdominal protrusions), evenly distributing abdominal pressure and effectively reducing the marks and gaps caused by traditional straight-line stitching.

[0045] A structurally reinforced pair of underwear, wherein the front body 10 and back body 20 of the underwear overlap and connect at the corresponding sides of the human abdomen to form a first overlapping portion 50 and a second overlapping portion 60, respectively. The first overlapping portion 50 and the second overlapping portion 60 extend upwards from the crotch area 30 to both sides to form a V-shaped structure. The V-shaped structure design, utilizing the extensibility of the fabric, can dynamically adjust with changes in waist circumference, precisely conforming to the natural curves from the waist to the abdomen (such as waist indentations and abdominal protrusions), evenly distributing abdominal pressure, and effectively reducing the need for traditional straight-line stitching. It avoids the problems of marks and gaps caused by tightness; it is especially suitable for people with uneven abdominal fat distribution or large changes in waist circumference, such as pregnant women (it can adapt to the changes in body shape as the abdomen protrudes and relieve discomfort caused by concentrated pressure on the waist), postpartum women (it fits the loose state of the abdomen and avoids fabric accumulation), and obese people (it avoids "waist constriction" and local pressure through elastic structure). It can adapt to different waist circumference sizes through structural adjustment, and can maintain a close fit in scenarios such as exercise and prolonged sitting, reducing the displacement or deformation caused by movement, and taking into account both comfort and functionality.

[0046] See Figure 1As shown, this application provides an embodiment of structurally reinforced underwear. The reinforced underwear includes a front body 10, a back body 20, and a crotch area 30. The corresponding sides of the front body 10 and the back body 20 overlap and connect at the abdomen to form a first overlapping portion 50 and a second overlapping portion 60, so that the front body 10 and the back body 20 form an abdominal circumference. The two sides of the crotch area 30 and the lower edge of the abdominal circumference form two first openings 40 for the legs to pass through. The first overlapping portion 50 and the second overlapping portion 60 extend upwards from the crotch area 30 in a V-shape towards both sides.

[0047] The aforementioned front part 10 of the underwear is designed to cover the abdominal area of ​​the human body; the aforementioned back part 20 of the underwear is designed to cover the buttocks area and part of the abdominal area, including the entire buttocks area, the sides of the waist and abdomen and the groin area.

[0048] The front body 10 and back body 20 of the underwear overlap and connect at the corresponding sides on the abdomen to form a first overlapping portion 50 and a second overlapping portion 60, respectively. This means that the two sides of the front body 10 and the two sides of the back body 20 overlap at the abdomen, forming a ring around the abdomen. The first overlapping portion 50 and the second overlapping portion 60 extend upward from the crotch 30 in a V-shape to both sides. This means that the first overlapping portion 50 and the second overlapping portion 60, formed by the overlap of the sides of the front body 10 and the back body at the abdomen, extend upward from the crotch 30 (the center of the bottom of the underwear) to the sides of the abdomen, forming an upward-opening V-shape.

[0049] There are no limitations on the material or thickness of the front panel 10, back panel 20, and crotch panel of the underwear. Different parts can be adjusted according to actual needs, so that the underwear can meet key functional requirements such as shaping, breathability, and sweat-wicking. Taking shaping as an example, the differentiated design of the elasticity of the front panel 10 and back panel 20 of the underwear achieves precise control of abdominal and hip fat, making the wearer visually present a tighter and more shapely figure. In some embodiments, the front body 10 of the underwear is less elastic than the back body 20 of the underwear. That is, the front body 10 of the underwear uses a relatively low elasticity fabric, which allows the front body 10 to closely fit the abdominal curve, effectively pressing the abdomen inward to prevent the abdomen from bulging and showing a flat abdominal line. Excess abdominal fat is squeezed towards the buttocks. The back body 20 of the underwear uses a more elastic fabric, which not only provides sufficient support to help shape a full and rounded buttocks, but also ensures the wearer's freedom and comfort during activities, gathering the excess fat of the abdomen and buttocks towards the buttocks, resulting in a good effect of tummy control and buttock lifting.

[0050] The human abdomen to waist area has a tapered structure that is narrower at the top and wider at the bottom. Preferably, the angle between the first overlapping portion 50 and the second overlapping portion 60 is between 30° and 45°. When the angle is less than 30°, the V-shape is too narrow, which will cause the fabric in the waist area to be too tight, increasing the risk of chafing marks. When the angle is greater than 45°, the V-shape is too wide, and the fabric on the sides of the abdomen is prone to loosening, resulting in wrinkles or shifting. An angle of 30°-45° can achieve a "pressure-free fit".

[0051] See Figure 2 As shown, the side connection structure plays a crucial role in improving overall fit and wearing stability. In some embodiments, the first overlapping portion 50 and the second overlapping portion 60 overlap at one end of the crotch portion 30 to form a third overlapping portion 70. This design achieves a stable "three-point" connection structure by fusing the front and back sides of the crotch portion 30. The presence of the third overlapping portion 70 not only enhances the connection strength between the crotch portion 30 and the front and back portions of the underwear, reducing stress concentration at the first and second overlapping portions 50 and 60, but also ensures more even stress distribution during wear, preventing deformation or wear caused by localized stretching, and significantly improving product durability and wearing comfort. Specifically, the third overlapping part 70 is provided with a third stitch line 701, which connects the first overlapping part 50, the second overlapping part 60 and the front of the underwear 10. That is, the third stitch line 701 is reinforced at the third overlapping part 70 at the V-shaped apex (the starting point of the crotch 30) to enhance durability.

[0052] The first overlapping portion 50 and the second overlapping portion 60 can employ an "inner overlock seam" or "separate press seam" technique, where the sides of the underwear front body 10 and the underwear back body 20 are overlapped and then sewn together to ensure a smooth seam that does not chafe the skin. In some embodiments, the corresponding sides of the underwear front body 10 and the underwear back body 20 overlap at the abdomen and are connected by a first seam 501 and a second seam 601, respectively. The first seam 501 is located at the first overlapping portion 50, and the second seam 601 is located at the second overlapping portion 60, forming a V-shape. This V-shaped seam layout not only effectively distributes pressure on the abdomen and waist during wear but also further enhances the fit and stability of the sides.

[0053] The first suture 501 and the second suture 601 can be located at any position in the first overlapping portion 50 and the second overlapping portion 60. In some embodiments, the first suture 501 and the second suture 601 are located on opposite sides of the first overlapping portion 50 and the second overlapping portion 60, that is, the first suture 501 and the second suture 601 are located on the side of the first overlapping portion 50 and the second overlapping portion 60 closer to the midline of the abdomen; the first suture 501 and the second suture 601 are close to the midline of the abdomen, and the V-shaped layout can form a converging force towards the midline of the abdomen. By pulling towards the center of the abdomen through the first suture 501 and the second suture 601, uniform pressure is provided to the rectus abdominis muscle area, which has a particularly auxiliary effect on the recovery of rectus abdominis diastasis.

[0054] To ensure the underwear sides maintain a stable mechanical structure while conforming to the body's curves, the first seam 501 and the second seam 601 are parallel to the corresponding edges of the first overlapping portion 50 and the second overlapping portion 60. Specifically, when the sides of the underwear front body 10 and the underwear back body 20 overlap to form the first and second overlapping portions 60, the first seam 501 is sewn parallel to the edge of the first overlapping portion 50 near the midline of the abdomen, and the second seam 601 is fixed parallel to the corresponding edge of the second overlapping portion 60. This parallel seam arrangement ensures that the direction of stress on the seams is consistent with the stretching direction of the fabric in the overlapping portion during wear, avoiding localized stress concentration due to angular deviations and reducing the risk of seam breakage. Simultaneously, the parallel seam layout further enhances the fit of the overlapping portion, ensuring the underwear remains stable during bending, turning, and other movements, significantly improving comfort and durability.

[0055] In some embodiments, an antibacterial portion may be attached to the inner surface of the crotch portion 30, which may be formed from bamboo fiber fabric with good breathability.

[0056] See Figure 3 As shown, to address the issue of underwear slipping down easily during wear, an additional elastic band 80 is added. The elastic band 80 connects to the top edges of the front body 10 and the back body 20 of the underwear. The elastic band 80 has good elasticity, allowing it to fit snugly against the waist and abdomen, thus securing the underwear. Specifically, the elastic band 80 is sewn to the top edges of the front body 10 and the back body 20 of the underwear after the underwear is positioned over the abdomen. The shape of the elastic band 80 can be straight, wavy, etc. In some embodiments, the side of the elastic band 80 away from the abdominal area is wavy. When the wavy edge contacts the skin, it forms a point-to-surface friction pattern, reducing the coefficient of sliding friction during movement. This is especially suitable for dynamic scenarios such as running and fitness, effectively preventing the elastic band 80 from rolling up due to friction displacement. The material of the elastic band 80 is not limited; it can be elastic lace, combining functionality and decoration.

[0057] To increase the contact area at the leg opening and prevent the opening from constricting the leg and causing marks, an elastic lining 90 may be included. In some embodiments, the elastic lining 90 may be directly connected to the first opening 40. See also Figure 4 and Figure 5 As shown, in some embodiments, the two elastic linings 90 are respectively connected to the first opening 40, and the width of the elastic linings 90 gradually decreases from the back body 20 of the underwear to the front body 10 of the underwear. The elastic linings 90 are wider at the back body 20 of the underwear, which can cover a wider area of ​​the buttocks. By increasing the force-bearing area, the pressure is dispersed, avoiding the marks or displacement caused by traditional narrow linings. It is especially suitable for the buttocks with obvious curves or for sports scenarios. The wide lining design can dynamically fit with the movement of the buttocks, reducing the problem of underwear slipping down due to walking or sitting for a long time, and improving the stability of wearing. The elastic linings 90 of the front body 10 and the crotch are narrower, which can avoid pressure on the abdomen and inner thighs.
