Description

Technical Field

[0001] This utility model relates to the field of clothing technology, specifically to a concealed elastic waistband structure for men's fitted casual trousers. It aims to solve the problems of unrefined appearance, poor wearing comfort, and insufficient waist coverage in existing casual trouser waistbands when realizing waist expansion function. Through a specific structural design, the casual trouser waistband can maintain a flat and wrinkle-free appearance while having good stretch elasticity, thereby improving the wearing experience and the range of applicable people. Background Technology

[0002] In the clothing industry, especially in the design and production of casual pants, the waistband is an important component of pants. It must not only meet the wearer's needs for waist adjustment to adapt to different body types and wearing conditions, but also ensure the overall appearance of the pants to meet modern consumers' pursuit of aesthetics in clothing.

[0003] Currently, the industry primarily employs two common technical solutions to achieve elasticity in trouser waistbands. The first solution involves adding elastic bands and ruching them at the waistband. The elasticity of the elastic bands stretches the waistband, thus adjusting the waist size. However, this solution has a significant drawback: the ruching design causes unevenness at the connection between the waistband and the trouser body, resulting in an unattractive and less refined appearance, failing to meet the demands of consumers who prioritize aesthetics.

[0004] The second option is to install or attach buckle loops at the waist, adjusting the waist size by changing the position of the loops. However, this option also has problems in practical application. When the waist size decreases, the waist area may become concave or convex due to the fixing effect of the buckle loops, resulting in an uneven waist. This unevenness not only affects the visual appearance of the pants but also creates an uncomfortable contact with the waist during wear, reducing comfort. Furthermore, the waist adjustment range is relatively limited, offering insufficient accommodating for people with different waist sizes.

[0005] In summary, existing elastic waistband technology for casual trousers has room for improvement in terms of appearance, wearing comfort, and waist circumference tolerance. It cannot adequately meet both functional and aesthetic requirements. Therefore, a new waistband structure design is urgently needed to solve the aforementioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a concealed elastic waistband structure for use in men's fitted casual trousers, in order to optimize the design of the fitted waistband of casual trousers.

[0007] A concealed elastic waistband structure includes a waistband face, a waistband lining, a first elastic band, a second elastic band, a concealed waistband lining loop, a pocket fabric, and pocket patches. The waistband face is separated from the side pocket opening of the casual pants, including a front center waistband face and a side and back waistband face. An extended concealed loop is provided at the front waistband pocket opening of the front center waistband face. After the extended concealed loop is spliced ​​with the concealed waistband lining loop, it is hidden between the side and back waistband face and the corresponding waistband lining. The waistband lining includes left and right front center waistband linings, which are separated with the separation length matching the length of the first elastic band. One end of the first elastic band is fixed to the seam of the pocket fabric with a flush seam and is covered by the front center waistband face. The other end is spliced ​​with the left front center waistband lining without revealing the seam. One end of the second elastic band is concealed and fixed to the middle layer between the back side waistband face and the waistband lining with a flush seam. The other end is connected to the extended concealed loop. The side of the pocket fabric has a U-shaped slit, and the slit is ironed to form a low seam and a seam. Pocket patches are respectively set at the connection between the left front center waistband lining and the right front center waistband lining and the first elastic band, 3cm off the side seam. The position is smaller than the opening width of the U-shaped slit of the pocket fabric. One side is spliced ​​with the first elastic band, and the other side is fixed with the corresponding front and middle waist lining. The whole is hidden between the first elastic band and the front and middle waist lining.

[0008] Furthermore, the ends of the extended concealed loop fabric are gradually narrowed, and when connected to the second elastic band, the seam of the second elastic band is completely hidden inside the side and back waist surface.

[0009] Furthermore, the front mid-waist panel after the waistband is split corresponds to the front waistband area of ​​the casual pants, and the side back waist panel corresponds to the side back waistband area; the left front mid-waist lining and the right front mid-waist lining correspond to the left and right sides of the front waistband area, respectively, and are adapted to the inner side of the front mid-waist panel.

[0010] Furthermore, there are two pocket patches, corresponding to the joint positions of the left front center waist lining and the right front center waist lining with the first elastic band, respectively. The seams of the pocket patches are not exposed, and the width is 2-3cm smaller than the width of the U-shaped opening of the pocket fabric.

[0011] Furthermore, both the first and second elastic bands are made of spandex with an elastic modulus of 300 N / m; the first elastic band is 7.5 cm long and the second elastic band is 5 cm long.

[0012] Furthermore, the width of the U-shaped opening of the bag fabric is the same as the length of the first elastic band, and the depth is 8cm.

[0013] Furthermore, the joint between the concealed waist loop and the extended concealed waist loop is completely hidden between the side and back waist surface and the corresponding waist lining, with no external joint marks.

[0014] Compared with the prior art, the concealed loop elastic waistband structure of this utility model has the following significant advantages: 1. By concealing the extended loops below the side and back waistband, using concealed stitching to secure the elastic band, and hiding the elastic band at the waistband's break point without exposing the seam, this design effectively avoids problems such as uneven waistbands caused by elastic band wrinkling and concave or convex waistbands caused by fastening loops in existing technologies. The overall waistband appearance is smooth, without obvious wrinkles or exposed parts, giving the casual pants a more refined look, meeting modern consumers' high-quality demands for clothing appearance, and enhancing the product's market competitiveness.

[0015] 2. This structure, through the use of a first elastic band and a second elastic band, combined with the splicing design of the extended concealed loops, the splicing of the waistband and elastic bands, and the U-shaped slits in the pocket fabric, forms a multi-position, multi-component synergistic elastic structure. When the wearer needs to adjust the waist circumference, each elastic band can exert its elasticity simultaneously, achieving effective stretching of the waistband. The stretching range can be controlled according to actual needs by adjusting the splicing length of the elastic bands and the splicing length of the extended concealed loops. Compared to the single elastic band gather or buckle adjustment method in existing technologies, the stretching adjustment function of this structure is more stable and the adjustment range is more flexible, better adapting to the wearer's waist circumference changes in different states.

[0016] 3. On the one hand, the smooth, wrinkle-free waistband avoids friction and pressure between uneven areas and the waist, reducing discomfort during wear. On the other hand, the synergistic stretch of multiple elastic bands provides even elastic support to the waist, ensuring a closer fit without excessive tightness, thus enhancing comfort. Simultaneously, the expanded effective stretch range of the waistband accommodates a wider range of waist sizes, allowing consumers with larger or smaller waists to find a comfortable fit. This significantly improves the versatility of the casual pants, broadening their applicability to different body types.

[0017] 4. By reinforcing the waistband edges with pocket patches and using specific types of fabrics and standardized splicing techniques, the connection stability between the various components of the waistband is enhanced, preventing issues such as component detachment, deformation, or wear during long-term wear and frequent stretching. The U-shaped vent design of the pocket fabric not only assists in achieving the stretch function but also disperses the concentrated effect of tensile force on the pocket fabric, reducing the risk of damage to the pocket fabric. This extends the lifespan of the entire waistband structure and even the casual pants, improving the product's durability and cost-effectiveness. Attached Figure Description

[0026] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model, such as... Figure 1-8 As shown: This embodiment provides a concealed elastic waistband structure, mainly concentrated at the waistband 11, applied to men's fitted casual trousers, and its specific structure is as follows: The waistband 1 is broken off from the side pocket opening of the casual pants. The front waistband 12 has a waistband extension loop 14 at the front waist pocket opening. The waistband extension loop 14 and the waist lining loop 5 are combined and hidden in the middle of the side back waistband 13 and the corresponding waist lining.

[0027] The first elastic band 3 is made of spandex with an elastic modulus of 300 N / m. The first elastic band 3 is sewn to the seam 62 and covered by the front waist 12. The stitch density is set to 12 stitches / inch and the length is 7.5 cm. The specific size can be adjusted according to the design details to ensure that the first elastic band 3 is firmly fixed and not exposed.

[0028] The waist lining 2 includes a left front-middle waist lining 21 and a right front-middle waist lining 22. The waist lining 2 is cut at the position between the left front-middle waist lining 21 and the right front-middle waist lining 22. The length of the gap at the cut point matches the length of the first elastic band 3. The other edge of the first elastic band 3 is wrapped inside the fabric of the left front-middle waist lining 21 to prevent the raw edges of the elastic band from being exposed (the first elastic band 3 is covered by the left front-middle waist lining 21, which is marked as an indication in the view).

[0029] The waistband lining 2 is cut off between the left front mid-waist lining 21 and the right front mid-waist lining 22. The second elastic band 4 has the same material and elastic coefficient as the first elastic band 3, and is 5cm long. The second elastic band 4 is embedded in the middle layer between the back waistband lining and the back waist surface, and is fixed under the side back loop using a blind stitching technique. The other end is connected to the extended blind loop 14. During the connection process, it is ensured that the seam of the second elastic band 4 is completely hidden inside the side back waist surface, and the elastic band trace cannot be seen from the outside. The end of the fabric at the extended blind loop 14 is gradually narrowed to allow for better movement at the cut of the waistband lining 2 and to prevent jamming.

[0030] The bag fabric 6 is made of pure cotton and has a U-shaped slit structure 61. The opening width of the U-shaped slit 61 is the length of the elastic band, and the depth is 8cm. A raised and lower seam is formed at the U-shaped slit 61 of the bag fabric 6 through an ironing process. The height of the seam 62 is 1cm higher than the lower seam. The seam 62 is joined to the first elastic band 3 using a flat seam technique. After joining, the seam 62 of the bag fabric 6 can move synchronously with the expansion and contraction of the first elastic band 3.

[0031] The width of the pocket patch 7 is less than the width of the U-shaped opening of the pocket fabric. The seam of the pocket patch 7 is at the same height as the U-shaped slit seam 62 of the pocket fabric, and it is joined with the first elastic band 3 and hidden between the first elastic band 3 and the front waist lining, with the rough seam not exposed.

[0032] In actual use, when the wearer's waist circumference changes, the first elastic band 3 and the second elastic band 4 will simultaneously undergo elastic deformation, causing the waist surface 1 and the waist lining 2 to stretch and contract accordingly. The two ends of the first elastic band 3 are connected to the front middle waist lining and the back side waist lining, respectively, while one end of the second elastic band 4 is fixed to the extended hidden loop 14. Therefore, the first elastic band 3 can expand or contract on the inside of the front middle waist surface 12 and the left front middle waist lining 21 by its own elasticity. The pocket fabric 6 is also sewn to the first elastic band 3. Because the U-shaped slit design allows the fabric near the slit to shift left and right, the U-shaped slit 61 and the sewn part 62 of the pocket fabric 6 are designed to provide sufficient space for the stretching and contraction of the first elastic band 3, while ensuring that the waistband always remains flat and wrinkle-free, achieving a perfect combination of exquisite appearance and stretch functionality.

[0033] As can be seen from the above embodiments, the concealed elastic waistband structure of this utility model can be adapted to the size, material, and process of each component according to different styles of casual pants, different usage scenarios, and different consumer groups. However, its core structure, including the waistband break and extension concealed loop design, the concealed fixing of the elastic, the waistband break and elastic hiding, and the pocket U-shaped slit and high and low seam design, can all achieve the core purpose of exquisite appearance without wrinkles, effective elasticity, and improved wearing comfort and inclusiveness, fully demonstrating the flexibility and practicality of this utility model.
