Detailed Implementation
[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides a down jacket for high altitudes. Figure 1 This diagram shows the overall structure of the high-altitude down jacket in an embodiment of the present invention. Figure 2The diagram shows a structural schematic of the connection between the placket and the hem in an embodiment of the present invention. The high-altitude down jacket includes a down jacket body. A main zipper 100 is provided at the placket of the down jacket body. Both sides of the main zipper 100 are provided with placket-equal down filling structures 200. There is a gap channel 300 between the two placket-equal down filling structures 200. The main zipper 100 is located on the side of the gap channel 300 away from the human body. A windproof strip 310 is provided in the gap channel 300. One side of the windproof strip 310 is fixedly set on the side of one of the placket-equal down filling structures 200 away from the human body, and the other side of the windproof strip 310 is free to move. The width of the windproof strip 310 is greater than the width of the gap channel 300, and the length of the windproof strip 310 is greater than or equal to the length of the gap channel 300.
[0025] This utility model of a high-altitude down jacket features equal-volume down-filled placket structures 200 on both sides of the main zipper 100, which eliminates weak points in the placket and effectively prevents the intrusion of cold air. Simultaneously, a windproof strip 310 is provided within the gap 300 between the two placket structures 200, which can conceal the gaps in the main zipper 100 and also effectively prevent the intrusion of cold air. In summary, by incorporating the equal-volume down-filled placket structures 200 and the windproof strip 310, this utility model effectively prevents cold air from intruding through weak points in the placket and gaps in the main zipper 100, thereby reducing heat loss and improving the comfort and safety of the down jacket.
[0026] In addition, the main zipper 100 is located on the side of the spacer channel 300 away from the human body, so that the two plackets with equal amount of down filling structure 200 will not cover the main zipper 100, thus avoiding affecting the normal opening and closing of the main zipper 100.
[0027] In some specific embodiments, please refer to Figure 2 The thickness of any of the equal-volume down filling structures 200 of the placket is the same as the thickness of the down jacket body. When the equal-volume down filling structure 200 of the placket reaches the same thickness as the down jacket body, it can significantly reduce the cold spot effect and effectively improve the overall warmth performance of the down jacket in high-altitude extreme environments.
[0028] In some specific embodiments, please refer to Figure 1 and Figure 2The down jacket body has a hem with equal down filling structure 400 at the hem, which is integrated with the placket with equal down filling structure 200 at the placket. Traditional down jackets often have less down filling at the hem to ensure flexibility and a snug fit, which can weaken warmth. This invention, by incorporating the hem with equal down filling structure 400, eliminates this weakness, effectively preventing cold air intrusion and reducing heat loss, thus improving comfort and safety.
[0029] For details, please refer to Figure 2 The thickness of the equal-volume down filling structure 400 at the bottom hem is the same as the thickness of the down jacket body. When the equal-volume down filling structure 400 at the bottom hem is the same as the thickness of the down jacket body, it can significantly reduce the cold spot effect and effectively improve the overall warmth performance of the down jacket in high-altitude extreme environments.
[0030] Furthermore, the side of the hem with equal amount of down filling 400 that comes into contact with the human body is provided with an elastic shrink band. The elastic shrink band design allows the hem with equal amount of down filling 400 to fit snugly against the human body, enhancing the warmth retention effect without affecting the wearer's normal activities.
[0031] For further details, please refer to Figure 1 The hem of the equal-volume down-filled structure 400 is equipped with a drawstring adjustment system 410 on the side furthest from the head. Figure 3 A schematic diagram of the drawstring adjustment system in an embodiment of this utility model is shown. The drawstring adjustment system 410 includes a drawstring channel 411 disposed within the hem equal-volume down-filled structure 400, an adjusting drawstring 412 passing through the drawstring channel 411, and an adjusting buckle 413 disposed on the adjusting drawstring 412. The adjusting buckle 413 is located outside the hem equal-volume down-filled structure 400. The drawstring adjustment system 410 can further adjust the tightness of the hem equal-volume down-filled structure 400, making it easier for the hem equal-volume down-filled structure 400 to fit snugly against the wearer's body, thereby further enhancing the warmth retention effect without affecting the wearer's normal activities.
[0032] In some specific embodiments, the connection between the placket equal-volume down filling structure 200 and the down jacket body is based on two stitches, and the connection between the hem equal-volume down filling structure 400 and the down jacket body is also based on two stitches. These two stitches ensure a strong and stable connection while minimizing gaps at the seams, preventing down from escaping and cold air from entering.
[0033] In some specific embodiments, the placket equal-volume down filling structure 200 and the main body zipper 100 are bonded together using adhesive strips. The adhesive strips are heat-pressed between the placket equal-volume down filling structure 200 and the main body zipper 100 to form a seamless connection, which not only ensures the smooth sliding of the main body zipper 100 but also achieves a good sealing effect.
[0034] In some specific embodiments, reinforcing linings or reinforced stitching are provided at the corners of the equal-volume down filling structure 200 of the placket and the corners of the equal-volume down filling structure 400 of the hem. This can improve the durability and stability of the down filling structure and ensure that the warmth performance of the down filling area is not affected during long-term use.
[0035] In some specific embodiments, the main zipper 100 is a waterproof zipper, which is thin, light, and has good sealing performance, effectively improving the waterproof and windproof performance of the zipper area without increasing the thickness too much. Specifically, the main zipper 100 is a waterproof taped zipper with tightly interlocking teeth, smooth zipper operation, and the zipper surface is treated with anti-scratch and wear-resistant treatment, making it suitable for frequent use in high-altitude environments.
[0036] In some specific embodiments, both the placket equal-volume down filling structure 200 and the hem equal-volume down filling structure 400 include down filling channels and down filling material filled within the down filling channels. The down filling material is goose down with a down content ≥90% and a fill power ≥800, providing strong warmth retention. Specifically, the down jacket body is also filled with goose down with a down content ≥90% and a fill power ≥800, resulting in strong overall warmth retention.
[0037] In some specific embodiments, the side of the hem with equal amount of down filling 400 that comes into contact with the human body is provided with a fleece fabric layer, which is soft and skin-friendly and helps to improve wearing comfort; the side of the hem with equal amount of down filling 400 that is away from the human body is provided with a wear-resistant and windproof fabric layer, which helps to enhance the protective performance of the hem and adapt to various usage scenarios in high-altitude environments.
[0038] In some specific embodiments, the outer layer of the down jacket body is a windproof and waterproof fabric, such as 20D nylon fabric with a waterproof index ≥10000mmH2O, excellent windproof performance, and good flexibility and abrasion resistance, meeting the usage requirements of high-altitude environments.
[0039] The high-altitude down jacket of this invention has the following effects:
[0040] (1) Significantly improved warmth performance: By filling the cold spots in the placket and hem with an equal amount of down filling structure and by covering the zipper gaps with windproof strips, the weak points in the traditional high-altitude down jacket design are eliminated, and the overall warmth performance of the high-altitude down jacket is improved by 20.3%, effectively resisting the severe cold in high-altitude areas and providing the wearer with strong warmth protection.
[0041] (2) It maintains the functionality and comfort of the garment: The equal amount of down filling structure cleverly balances warmth and functionality of the garment, without affecting the normal opening and closing of the main zipper and the flexibility of the hem, ensuring that the wearer can move freely in high-altitude activities and at the same time obtain a comfortable wearing experience.
[0042] (3) Enhance product durability: Double stitching design, reinforced lining or reinforced stitching design, etc., effectively improve the durability of the equal amount of down filling structure, reduce the probability of down filling structure deformation problems, and extend the service life of high-altitude down jackets.
[0043] The above provides a detailed description of a high-altitude down jacket provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
