Description

Technical Field

[0001] This utility model relates to the field of trousers technology, specifically to a comfortable trouser waistband structure. Background Technology

[0002] In traditional trouser design, the waistband typically uses a fixed or adjustable elastic band to achieve a snug fit, but this has several limitations. For example, the fixed elastic band in common trouser waistbands is often sewn directly inside the waistband, covering the entire waist area. This can easily cause the fabric to bunch up, creating a bulky appearance and ruining the overall shape of the garment. Furthermore, after prolonged wear, the elastic band is prone to aging and loosening due to repeated stretching, losing its elasticity and support, and failing to maintain a stable fit around the waist, resulting in slippage or sagging.

[0003] On the other hand, some waistband designs attempt to improve the fit with adjustable elastic bands, but the adjustment structure is often exposed, affecting aesthetics and making it inconvenient to operate. For example, some designs have buttons or Velcro on the front of the waistband, but these components may rub against outer clothing or generate noise when worn, reducing the user experience. Utility Model Content

[0004] The purpose of this utility model is to provide a comfortable waistband structure to solve the problems of poor comfort, freedom of movement, and poor appearance of the existing waistband structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A comfortable waistband structure includes a pant body and a waistband located at the upper end of the pant body. An elastic opening is provided at the center axis of the back of the waistband, with the upper end of the elastic opening extending through the upper edge of the waistband. A fixing opening is provided on each of the left and right sides of the waistband within the elastic opening, and the two fixing openings are symmetrically distributed along the center axis of the back of the waistband. An elastic band is provided within the elastic opening, with both ends of the elastic band inserted into the two fixing openings for fixation. A limiting stitch is sewn at the center axis of the back of the waistband, below the elastic opening, to restrict the maximum opening range of the elastic opening. A magnetic attraction assembly is provided near each of the two fixing openings, and the magnetic attraction assemblies attract each other.

[0007] Preferably, a double-layer anti-slip interlayer is provided on the side of the fixing opening away from the elastic opening. The inner layer is fixedly connected to the end of the elastic band by a heat-pressing process, and the outer layer is sewn to the waistband to fix the end of the elastic band in the fixing opening away from the elastic opening.

[0008] Preferably, the elastic band includes a main elastic section in the middle and auxiliary elastic sections at both ends. The length of the main elastic section is 1 / 2 of the total length of the elastic band, and the width of the main elastic section is 0.3-0.5 cm wider than the auxiliary elastic sections.

[0009] Preferably, the elastic coefficient of the main elastic segment is 15-20 N / cm, and the elastic coefficient of the secondary elastic segment is 8-12 N / cm.

[0010] Preferably, a flexible cushioning pad is sewn onto the outer side of the main elastic segment, the shape of which is adapted to the main elastic segment and the edges are rounded.

[0011] Preferably, the magnetic suction assembly includes a plurality of miniature magnetic blocks spaced apart along the width of the waistband. The surface of each miniature magnetic block is covered with a wrapping layer. One side edge of the wrapping layer is on the same plane as the opening edge of the fixing opening. The remaining side edges of the wrapping layer extend into a sewing area, which is sewn and fixed to the inner wall of the fixing opening, thereby fixing the miniature magnetic blocks inside the fixing opening.

[0012] Preferably, the edge of the elastic opening is sewn with a wavy edge that matches the fabric of the waistband, and a fleece lining is sewn on the inside of the wavy edge.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This invention provides a comfortable waistband structure. Through the coordinated action of the elastic band's contraction force and the magnetic components, in a natural state, the micro-magnetic blocks and the elastic band work together to ensure that the edge of the elastic opening fits tightly, forming a narrow, invisible line, thus solving the aesthetic problem of exposed elastic openings in existing designs. When squatting, the pushing force of the lower back can easily overcome the magnetic force, causing the elastic band to stretch and the elastic opening to unfold in a V-shape. Furthermore, the maximum unfolding range is limited by the hollow double-line limiting stitching on the lower side. This satisfies the waist expansion needs during activities while preventing the opening from excessively unfolding and damaging the garment's shape, achieving a smooth switch between concealment and stretch.

[0022] Example

[0023] Please refer to Figures 1 to 5 As shown, this utility model discloses a comfortable waistband structure, including a pant body 1 and a waistband 2 set at the upper end of the pant body 1. The fabric of the pant body 1 is a cotton-elastic blend to ensure basic breathability and drape. The waistband 2 has a double-layer structure, with the inner layer being skin-friendly cotton and the outer layer being the same as the fabric of the pant body 1. The overall width of the waistband is set to 4cm (that is, the distance from the upper edge of the waistband to the connection point of the pant body).

[0024] A long, narrow elastic opening 3 is located at the center axis of the back of the waistband 2. The elastic opening 3 is 2cm long, with its upper end extending through the top edge of the waistband 2 (i.e., the upper end of the elastic opening is flush with the top edge of the waistband), and its lower end extending to the midpoint of the height of the waistband 2. On the left and right sides inside the elastic opening 3, i.e., on the back fabric of the waistband 2, there is a fixing opening 4. The two fixing openings 4 are precisely symmetrically distributed along the center axis of the back of the waistband 2.

[0025] Elastic band 5 is placed inside elastic opening 3, with both ends of elastic band 5 inserted and fixed into two fixing openings 4 respectively. In order to control the degree of expansion of elastic opening 3 under stress and prevent it from tearing excessively, a horizontal limiting line 6 is sewn on the back center axis of waistband 2 and below elastic opening 3. The limiting line 6 sews the lower end of elastic opening 3, so that elastic opening 3 unfolds in a V-shape and limits the maximum opening range of elastic opening 3.

[0026] Inside each of the two fixed openings 4 and near the opening of the elastic opening 3, there is a set of magnetic components 7. The two sets of magnetic components 7 have opposite magnetic properties. When the two ends of the elastic band 5 are fixed, they can attract each other, thereby pulling the two sides of the elastic opening 3 together, so that it remains flat and inconspicuous in appearance.

[0027] A double-layer anti-slip interlayer 8 is provided on the side of the fixing opening 4 away from the elastic opening 3. This double-layer anti-slip interlayer 8 includes an inner layer and an outer layer. The inner layer is firmly bonded to the end of the elastic band 5 using a heat-pressing process (e.g., high-temperature ironing or ultrasonic welding). The outer layer covers the inner layer and is sewn to the fabric of the waistband 2. Through this structure, the end of the elastic band 5 is firmly clamped and sealed within the double-layer anti-slip interlayer 8, effectively preventing the elastic band 5 from slipping out of the fixing opening 4 or shifting during use, greatly improving the reliability and durability of the structure.

[0028] The elastic band 5 includes a main elastic section 51 in the middle and auxiliary elastic sections 52 at both ends. The length of the main elastic section 51 is half the total length of the elastic band 5, so that it corresponds to the center area of ​​the user's lower back when worn. In order to provide differentiated support, the width of the main elastic section 51 is 0.4 cm wider than the width of the auxiliary elastic sections 52 (preferably within the range of 0.3-0.5 cm).

[0029] The primary elastic section 51 has an elastic coefficient of 15-20 N / cm to provide the main support for the core waist area; while the secondary elastic section 52 has an elastic coefficient of 8-12 N / cm to provide a gentler lateral tension. This gradient elasticity design makes the pressure distribution on the waistband more even, avoiding discomfort caused by localized tightness.

[0030] A flexible cushioning pad 53 is sewn onto the outer side of the main elastic segment 51 (i.e., the side facing the user's waist). The shape of the flexible cushioning pad 53 is adapted to the wide part of the main elastic segment 51, completely covering the main elastic segment 51. Its edges are rounded to avoid friction and pressure on the skin that may be caused by right-angled edges. The flexible cushioning pad 53 can be made of soft velvet, sponge or silicone material to directly improve the comfort of contact with the skin.

[0031] The magnetic component 7 includes three miniature magnetic blocks 71 spaced apart along the width of the waistband 2 (the number can be adjusted as needed). The surface of each miniature magnetic block 71 is covered with a wrapping layer 72. The wrapping layer 72 is made of textile fabric.

[0032] One side edge of the wrapping layer 72 (i.e. the side closer to the elastic opening 3) is on the same plane as the opening edge of the fixing opening 4, so that the magnetic suction assembly 7 can be aligned when closed. The other three side edges of the wrapping layer 72 extend outward to form a stitching area 73. The stitching area 73 is stitched and fixed to the inner wall of the fixing opening 4 by stitches, thereby firmly and concealedly installing the entire magnetic suction assembly 7 inside the fixing opening 4.

[0033] A wavy binding (not shown in the figure) is sewn along the edge of the elastic band 3. The fabric used for this wavy binding is the same as that of the waistband 2, ensuring visual uniformity and aesthetics. A fleece lining is also sewn onto the inside of the wavy binding. This fleece lining comes into direct contact with the elastic band 5 or the user's skin, providing a soft and smooth feel, further preventing friction and discomfort, and enhancing the overall quality of the product.

[0034] The working principle of this embodiment is as follows:

[0035] Natural wearing state: The elastic band 5 contracts due to its own elasticity (18N / cm elastic force in the main elastic section), which drives the opening edges of the two fixing holes 4 to move closer to each other. At the same time, the two sets of magnetic components 7 (0.8N magnetic strength) attract each other, making the edges of the elastic opening fit tightly together, forming an invisible line with a width of ≤0.1cm, completely hiding the elastic structure and making the appearance flat.

[0036] In the squatting position: The lower back of the body exerts a pushing force on the waistband (approximately 1.5N, greater than the magnetic attraction strength). This pushing force overcomes the magnetic attraction, causing the elastic band 5 to stretch (the secondary elastic section 52 stretches first, while the main elastic section 51 provides support). This causes the opening edges of the two fixed openings 4 to separate, and the elastic opening 3 unfolds in a V-shape. When the unfolding reaches the limit of the limiting line 6, the inner limiting line is tightened, preventing the elastic opening 3 from unfolding further and avoiding excessive stretching of the fabric. At this time, the flexible cushioning pad 53 contacts the lower back, cushioning the stretching pressure of the elastic band 5 and ensuring that there is no feeling of tightness around the waist.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
