Abstract
Description
Technical Field
[0001] This application relates to the field of underwear technology, specifically to an underwear structure. Background Technology
[0002] With the steady improvement of residents' quality of life, the intimate apparel market is undergoing a profound transformation driven by consumption upgrading. Consumers' demands for underwear have evolved from basic functions of covering the body to a more complex demand that emphasizes both fashion aesthetics and wearing experience.
[0003] In actual wearing experience, traditional underwear leg openings are designed based on static human body models, failing to provide the three-dimensional space required for thigh movement. Their elastic structure and tailoring cannot accommodate the increased muscle volume and stretching demands during thigh flexion, especially during lower limb exercises like brisk walking and running. The fixed circumference of traditional underwear leg openings easily creates lateral constriction during movement. This tightness not only restricts normal leg flexion and extension but also creates continuous pressure in the groin area, causing the wearer to unconsciously adjust their posture. Furthermore, it easily leads to "rolling and shifting." During daily walking, due to friction between the thigh and the underwear fabric, the insufficiently elastic leg opening gradually slides upwards, frequently getting stuck in the groin area. This repeated shifting not only affects wearing comfort but can also cause excessive friction in certain areas, leading to thickened skin, pigmentation, and even contact dermatitis. Utility Model Content
[0004] In view of the above problems, this application provides an underwear structure that solves the problem that existing underwear restricts the normal flexion and extension of the legs.
[0005] To achieve the above objectives, the inventor provides an underwear structure comprising a front panel, a back panel, and a crotch area. The two sides of the front panel and the two sides of the back panel overlap at the front of the legs, forming an abdominal circumference by at least a first and a second seam. At the corresponding connection points of the two sides of the front and back panels, a first angle, either arc-shaped or V-shaped, is formed. The first seam connects the top edge of the overlapping area of the front and back panels. The second seam connects the two sides of the overlapping area and forms a second angle with either the two sides of the front or back panel. The crotch area connects the bottom edges of the front and back panels, and the two sides of the crotch area and the bottom edge of the abdominal circumference form two first openings for the legs to pass through.
[0006] Furthermore, the angle range of the first included angle is 60°-90°.
[0007] Furthermore, the two sides of the front and back pieces of the underwear overlap on the front side of the human legs to form a triangle.
[0008] Furthermore, it also includes an elastic band, which is sewn onto the top edge of the front and back pieces of the underwear after the sides of the front and back pieces of the underwear overlap on the front side of the human legs, so that the top edge of the overlapping part of the front and back pieces of the underwear forms the first seam.
[0009] Furthermore, the elastic band is wavy on the side away from the abdominal circumference.
[0010] Furthermore, the elastic band is an elastic lace trim.
[0011] Furthermore, it also includes elastic linings, with two elastic linings respectively connected to the front panel of the underwear, the front panel of the underwear and both sides of the crotch area. The two ends of the elastic linings overlap and together with the front panel and the back panel of the underwear form the abdominal circumference.
[0012] Furthermore, the second seam connects the elastic lining connecting the front and back pieces of the underwear; or
[0013] The second seam connects the elastic lining to the front panel of the underwear and the back panel of the underwear.
[0014] Furthermore, the width of the elastic lining gradually decreases from the back panel of the underwear to the front panel of the underwear and the direction of the elastic lining.
[0015] Unlike existing technologies, the above-mentioned technical solution precisely matches the muscle curve changes of the front of the legs during movement, ensuring that the underwear remains stable and fits well during exercise, reducing the frequency of adjustments caused by displacement. The first and second sutures can be quickly sewn together. At the same time, the connection method of the second suture creates a small three-dimensional space in the abdominal area, increasing air circulation channels. Compared with flat sutures, it can locally improve air circulation, accelerate sweat evaporation, reduce the irritation of the skin by the hot and humid environment, and effectively prevent skin problems caused by bacteria growth due to stuffiness.

[0045] An underwear structure is provided, wherein the two sides of the front panel 10 and the two sides of the back panel 20 are connected at the front of the human legs, forming an arc-shaped concave contour or an angled cut structure at the front of the human legs. The arc or V-shaped opening can precisely match the muscle curve changes of the front of the human legs during movement. When the thighs flex forward, the structure can naturally extend with the contraction of the quadriceps muscles, avoiding the tightness and pulling feeling caused by traditional straight edge designs, so that the underwear remains stable and fits during movement, reducing the frequency of adjustment caused by displacement; when connected, it is connected by at least a first seam 40 and a second seam 50. The first seam 40 connects the top edge of the overlapping part of the front panel 10 and the back panel 20; the second seam 50 connects the two sides of the overlapping part of the front panel 10 and the back panel 20, and forms an angle with the two sides of the front panel 10 or the two sides of the back panel 20. The first suture 40 and the second suture 50 enable quick stitching. The first suture 40 prevents the top edge from curling, while the second suture 50 reinforces both sides by forming an angle with the side edge. Even under frequent stretching during exercise, the shape of the leg opening remains stable, extending the lifespan of the underwear and reducing the decline in wearing experience caused by structural deformation. At the same time, the connection method of the second suture 50 creates a small three-dimensional space around the abdomen, increasing air circulation channels. Compared to flat stitching, this locally improves airflow, accelerates sweat evaporation, reduces the irritation of the skin by the hot and humid environment, and effectively prevents skin problems caused by bacteria growth due to stuffiness.
[0046] See Figure 1 and Figure 2 As shown, this application provides an embodiment of an underwear structure, which includes a front piece 10, a back piece 20, and a crotch area 30. The two sides of the front piece 10 and the two sides of the back piece 20 overlap on the front side of the human legs and are connected by at least a first seam 40 and a second seam 50 to form an abdominal circumference. At the corresponding connection points between the two sides of the front piece 10 and the two sides of the back piece 20, a first included angle α, either arc-shaped or V-shaped, is formed. The first seam... Line 40 connects the top edge of the overlapping area of the front piece 10 and the back piece 20 of the underwear; the second stitch 50 connects the two sides of the overlapping area of the front piece 10 and the back piece 20 of the underwear, and forms a second included angle β with the two sides of the front piece 10 or the two sides of the back piece 20 of the underwear; the crotch 30 is connected between the bottom edges of the front piece 10 and the back piece 20 of the underwear, and the two sides of the crotch 30 and the lower edge of the abdominal circumference form two first openings 60 for the human legs to pass through.
[0047] The aforementioned front panel 10 corresponds to the abdominal area; the aforementioned back panel 20 corresponds to the buttocks area. There are no limitations on the material or thickness of the front panel 10, back panel 20, and crotch area 30; different parts can be adjusted according to actual needs, thus enabling the underwear to 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 achieves precise control over abdominal and buttock fat, resulting in a more toned and shapely figure for the wearer. In some embodiments, the front panel 10 of the underwear is less elastic than the back panel 20, meaning that the front panel 10 uses a relatively low-elasticity fabric, allowing it to closely conform to the abdominal curve, effectively pressing the abdomen inward to prevent it from bulging and creating a flat abdominal line. Excess abdominal fat is squeezed towards the buttocks. The back panel 20, on the other hand, 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 of movement and comfort, gathering excess fat from the abdomen and buttocks towards the buttocks, resulting in a good effect of tummy control and buttock lifting.
[0048] The two sides of the front panel 10 and the two sides of the back panel 20 of the underwear overlap at the front of the legs, and are connected by at least the first seam 40 and the second seam 50 to form an abdominal circumference. This means that the two sides of the front panel 10 and the back panel 20 overlap at the front of the legs; by sewing the overlapping parts together with at least the first seam 40 and the second seam 50, an abdominal circumference is formed around the abdomen. During sewing, the top edge of the overlapping area of the front panel 10 and the back panel 20 is sewn with the first seam 40. This makes the upper edge of the waistband more secure and less prone to curling. It should be noted that there are two options for the sewing method of the first seam 40: it can be continuously sewn along the entire length of the top of the overlapping area of the front and back panels; or it can be intermittently sewn only a portion of the top of the overlapping area. Both methods can achieve structural fixation of the abdominal circumference. The second seam 50 sews the side edges of the overlapping area between the front and back edges of the underwear 10 and the back edge of the underwear 20. The second seam 50 forms a second angle β with the side edge of the front or back edge of the underwear 10. This stitching method allows the underwear to fit the body curve better at this position and can also distribute the pulling force on the waist when the thighs move, reducing the feeling of being constricted in the waist.
[0049] At the corresponding connection points between the two sides of the front panel 10 and the two sides of the back panel 20 of the underwear, an arc-shaped concave or V-shaped first angle α is formed to ensure that the two sides of the front panel 10 and the two sides of the back panel 20 form an abdominal circumference that does not obstruct thigh movement. Preferably, the angle α is in the range of 60°-90°, and the cut structure within the 60°-90° angle range can extend autonomously with muscle deformation. The arc-shaped angle refers to the angle formed by the arc-shaped tangents at the corresponding connection points of the front panel 10 and the back panel 20 of the underwear.
[0050] The overlapping areas of the two sides of the front panel 10 and the back panel 20 of the underwear on the front side of the human legs can be designed in various shapes, specifically determined by the shape of the connection between the two sides of the front panel 10 and the back panel 20. In some embodiments, the overlapping areas of the two sides of the front panel 10 and the back panel 20 on the front side of the human legs form a triangle.
[0051] See Figure 2 As shown, in some embodiments, an antibacterial part 70 may also be attached to the inner surface of the crotch 30, and the antibacterial part 70 may be formed from bamboo fiber fabric with good breathability.
[0052] 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 the top edges of the front panel 10 and the back panel 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. In some embodiments, the elastic band 80 is sewn to the top edges of the front panel 10 and the back panel 20 after their sides overlap at the front of the legs, forming the first seam line 40 at the point of overlap. The elastic band 80 can be straight, wavy, or similar. In some embodiments, the elastic band 80 is wavy on the side away from the abdominal area. The wavy edge creates a point-to-surface friction pattern when in contact with the skin, reducing the coefficient of sliding friction during movement. This is particularly suitable for dynamic activities such as running and fitness, effectively preventing the elastic band 80 from rolling up due to friction displacement. There are no restrictions on the material of the elastic band 80; it can be elastic lace trim, combining functionality and decoration.
[0053] To increase the contact area at the leg opening and prevent it 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 60. See also Figure 4As shown, in some embodiments, the two elastic linings 90 are respectively connected to the front panel 10 of the underwear, the crotch area 30, and the two ends of the elastic linings 90 overlap and together with the front panel 10 and the back panel 20 of the underwear to form an abdominal circumference. Specifically, the second seam 50 connects the elastic linings 90 connected to the front panel 10 and the back panel 20 of the underwear; or the second seam 50 connects the elastic linings 90 connected to the front panel 10 and the back panel 20 of the underwear.
[0054] The aforementioned elastic lining 90 can be straight, meaning the width of the entire elastic lining 90 is the same; see [link / reference]. Figure 5 As shown, it can also be curved, meaning that the elastic lining 90 gradually narrows in width from the back panel 20 of the underwear to the front panel 10 of the underwear. The elastic lining 90 is wider at the back panel 20 of the underwear, covering a wider area of the buttocks. By increasing the pressure-bearing area, it disperses pressure and avoids marks or shifting caused by traditional narrow edges. It is especially suitable for areas with prominent buttock curves or for sports activities. The wide edge 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 wearing stability. The elastic lining 90 of the front panel 10 and crotch 30 of the underwear is narrower, which can avoid pressure on the abdomen and inner thighs.
[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
