Detailed Implementation
[0032] 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 protection scope of the present utility model.
[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0034] Reference Figures 1-6 This utility model discloses an adjustable children's down pants with multi-dimensional protective functions, including a main pant 1. The main pant 1 is made of high-density fabric and filled with lightweight down to achieve good warmth retention. The crotch area is designed with an arched stitching structure and is inlaid with a four-way elastic panel 7, as shown in the attached figure. Figure 2 As shown. The bow-shaped seam consists of two symmetrical arcs with a radius of curvature ranging from 150mm to 250mm, ensuring sufficient stretch in the crotch area during running, jumping, squatting, and other movements. The four-way elastic patch 7 is made of spandex blended fabric or high-elastic knitted fabric with a tensile strength of not less than 300N and a rebound rate of not less than 90%. When children wear down pants for exercise, the bow-shaped seam and the elastic patch work together to provide extra stretch, avoiding the pulling and constricting feeling of traditional straight crotch seams. In addition, the bow-shaped crotch seam can be replaced with a wavy or segmented arc splicing design to adapt to different sports needs. For example, in skiing scenarios, a wavy crotch seam can further improve stretch performance and meet the needs of large-amplitude leg movements.
[0035] The knee area features a three-dimensional "shell-soft" composite protective zone, the structure of which is shown in the attached diagram. Figure 3As shown. The outer flexible TPU shell 3 has a thickness ranging from 0.8mm to 1.2mm and a Shore hardness of 70A to 85A, capable of withstanding impact energy of no less than 50J, providing effective protection for the knees. The middle cushioning foam layer 9 is made of EPE or EVA material, with a thickness ranging from 3mm to 6mm and a compression deformation rate of no more than 10%, absorbing the impact force during exercise. The outer surface abrasion-resistant fabric layer 10 is made of Kevlar fiber fabric or high abrasion-resistant polyester fabric, with an abrasion resistance index of no less than 10,000 cycles of friction testing, enhancing durability. The three-layer structure is fixed by a pouch-like combination design and has a reserved replacement port 11 for easy cleaning or replacement. For example, when children are climbing outdoors, their knees frequently come into contact with the ground. The TPU shell 3 and the abrasion-resistant fabric layer 10 work together to prevent knee abrasions; at the same time, the cushioning foam layer 9 absorbs impact force, reducing the risk of injury.
[0036] The waistband features a three-dimensional anti-slip structure, with silicone particles (8) arranged on the inner side. These particles range in diameter from 1mm to 2mm and are spaced 5mm to 10mm apart, and are fixed to the inner side of the belt using a heat-pressing process. (See attached image) Figure 6 As shown, the silicone particles 8 provide uniform friction when in contact with the skin, preventing the waistband from slipping during vigorous exercise. The 3D anti-slip waistband 15 has a width ranging from 30mm to 40mm, while the inner waistband has a width ranging from 20mm to 30mm. The two layers are connected by an elastic connector, forming a double-layer waistband design to further enhance stability. For example, when a child plays basketball, their waist swings violently; the silicone particles 8 and the double-layer waistband work together to ensure the pants fit the body snugly and prevent them from slipping down.
[0037] The zipper pull 13 at the placket features a rounded, thickened T-shaped pull tab and is fitted with a soft silicone sleeve 14, as shown in the attached image. Figure 5 As shown. The zipper pull 13 has a length ranging from 20mm to 30mm, a width ranging from 10mm to 15mm, and a thickness ranging from 2mm to 3mm; the silicone sleeve 14 has a thickness ranging from 0.5mm to 1mm, a Shore A hardness of 30A to 40A, and an edge chamfer radius of not less than 1mm to reduce injury to the hands from sharp edges. For example, when children operate the zipper during daily wear, the rounded, thickened T-shaped zipper pull combined with the soft silicone sleeve 14 significantly reduces the risk of pinching injuries, making it especially suitable for young children.
[0038] A circular drawstring channel is provided on the inside of the trouser leg, through which a retractable adjustable drawstring 12 is threaded, and two positioning buckles 5 are provided at the exit of the drawstring channel, as shown in the attached diagram. Figure 4As shown. The width of the circular drawstring track ranges from 5mm to 8mm, and the diameter of the adjusting cord 12 ranges from 2mm to 3mm. It is made of polyester fiber with a tensile strength of not less than 200N. The two-section positioning buckles 5 are spaced 20mm to 30mm apart and are secured by a press-type locking mechanism. As the child grows, the cuffs can be pulled inwards by tightening the adjusting cord 12 to create a fold, thereby adjusting the pant length and extending the lifespan of the down pants. For example, when a child grows from 120cm to 130cm, the pant length can be adjusted using the two-section positioning buckles 5 to meet the wearing needs of different height stages. Furthermore, the pant leg adjustment structure can also achieve length adjustment through hidden folds combined with snaps or zippers, further improving adaptability.
[0039] Working principle: The main body of the pants 1 uses high-density fabric as the outer layer, filled with lightweight down. The high-density fabric reduces down leakage and blocks the intrusion of cold air. The down stores air through its fluffy structure, utilizing the low thermal conductivity of air to form an insulation layer, providing children with the basic warmth they need in winter. At the same time, the high-density fabric has a certain degree of tear resistance, providing structural support for the overall pants and ensuring durability for daily wear. The crotch area features an arched stitching design composed of two symmetrical arc lines, combined with an embedded four-way elastic panel 7 and a protective layer 6. When children perform large-scale movements such as running, jumping, and squatting, the arched seam provides greater deformation space compared to traditional straight crotch seams. The four-way elastic patch 7 is made of spandex blended fabric, four-way stretch woven fabric, or high-elastic knitted fabric, which undergoes multi-directional elastic deformation simultaneously. The two work together to increase the crotch stretch margin and avoid the pulling and constricting feeling caused by traditional straight crotch seams. At the same time, the protective layer 6 covers the easily worn areas of the crotch, reducing friction wear of the crotch fabric during exercise, extending the service life of the crotch area, and achieving a balance between flexibility and protection. The three-dimensional "shell-soft" composite protection area of the knee consists of an outer flexible TPU shell 3, a middle cushioning foam layer 9, and an outer wear-resistant fabric layer 10. The three-layer structure is fixed by a pouch-like combination. When the knee is subjected to external impact or friction, the outer TPU shell 3 first resists direct external impact, preventing sharp objects from directly contacting the knee skin; the middle cushioning foam layer 9 absorbs impact energy through its own compression deformation, converting the impact force into deformation energy, reducing the transmission of impact force to the knee bones and muscles; the outer wear-resistant fabric layer 10 reduces friction wear between the knee and the ground, clothing, etc. during daily exercise, further protecting the TPU shell 3 and the cushioning foam layer 9. In addition, the wear-resistant fabric layer 10 has a reserved replacement port 11 inside, which allows for the individual replacement of the corresponding layer when a certain layer is worn or dirty, without the need to replace the entire protective area, reducing maintenance costs and ensuring the long-term protective performance of the protective area. The waist adopts a three-dimensional anti-slip waist belt 15 structure, and the silicone particles 8 are fixed to the inside of the waist belt through a hot pressing process. When children wear trousers, the silicone particles 8 come into contact with the skin around the waist. Utilizing the high coefficient of friction of silicone, this enhances the friction between the belt and the skin. Simultaneously, the 3D anti-slip belt 15 features a double-layered design, increasing the contact area between the belt and the waist for a better fit. During vigorous activities such as basketball or running, which cause frequent waist movement, the friction of the silicone particles 8 and the supportive fit of the double-layered belt work together to prevent the waistband from slipping down, ensuring the trousers remain securely fitted throughout the activity and preventing any impact on movement or safety hazards caused by the waistband slipping off. The zipper pull 13 features a rounded, thickened T-shaped pull tab and is covered with a soft silicone sleeve 14.When children operate the zipper, the rounded and thickened T-shaped pull tab is easy to grip, reducing the risk of the pull tab slipping. The soft silicone sleeve 14 can cover the sharp edges of the zipper head 13, preventing children's hands from being scratched or pinched by sharp edges while pulling the zipper. At the same time, the protective sleeve 14 covers the connection between the zipper teeth 2 and the zipper head 13, reducing the possibility of the zipper teeth 2 pinching children's skin, comprehensively improving the safety of zipper use, especially suitable for the operation and wearing needs of young children. A circular drawstring channel is set inside the hem 4, and an adjustment cord 12 is threaded inside the drawstring channel.
