Abstract
Description
Technical Field
[0001] This utility model relates to the field of down jacket technology, and more specifically to a modular down jacket with a detachable down core. Background Technology
[0002] Down jackets are made of down and feathers, and contain air. Air has minimal thermal conductivity, preventing heat loss. In cold winters, lightweight down jackets have replaced heavy cotton-padded coats, becoming a common choice for warmth. However, frequent washing reduces the insulation of down jackets. Therefore, many down jackets now consist of a detachable outer jacket and a lining. Existing detachable down jackets often have a problem: poor connection between the down filling and the outer jacket. The down filling and outer jacket tend to shift during wear, especially at the shoulders and sleeves. When the hands move, the down filling moves with the outer jacket, but the outer jacket remains stationary. Furthermore, the sleeves of the down filling tend to roll up to the upper arms, affecting comfort. Therefore, we propose a modular down jacket with a detachable down filling. Without altering the structure, we add fasteners at the shoulders and cuffs to ensure a more secure fit between the down filling and the inner jacket, resulting in greater comfort.
[0003] To make down jackets more comfortable to wear, easier to wash separately, and to maintain their warmth, Chinese Patent (Authorization Announcement No.: CN221962927U) discloses a men's down jacket. This utility model includes a down jacket body, with first covering edges sewn to both sides of the body, sleeves located inside the first covering edges, and a second covering edge sewn to the top of the body, with a collar located inside the second covering edge. The sleeves and collar are equipped with convenient mechanisms at their ends, and the sleeves and collar are connected to the down jacket body via zippers. The sleeves include an outer sleeve cover, with a [missing information - likely a design feature] inside the outer sleeve cover. The garment features an inner sleeve and an outer sleeve with a down lining sandwiched between them. Two sets of female snap buttons are arranged in a ring around the top and bottom of the inner wall of the outer sleeve, and two sets of male snap buttons are arranged in a ring around the top and bottom of the outer wall of the down lining. A guide rod is provided on the outer wall of the inner sleeve, and a guide groove is provided on the inner wall of the down lining. This invention makes the sleeves and collar of the down jacket detachable, allowing the wearer to quickly and easily remove them from the jacket body using a zipper. This facilitates targeted disassembly and washing of the sleeves and collar, reducing cleaning workload while improving disassembly and assembly efficiency.
[0004] The solution still has some shortcomings in application. When the down inner core and the outer jacket are detachable and fitted together, the most prone parts to displacement are the shoulders and cuffs. Especially when wearing the jacket, the wearer's arms move, and the down inner core moves with the arms, but the outer jacket often does not follow, causing displacement. At the same time, the cuffs are also prone to causing the down inner core to shrink upwards due to arm movement. Therefore, the structure of the down jacket needs to be improved so that the down inner core and the outer jacket can fit better and cooperate with the wearer to improve comfort. Utility Model Content
[0005] This utility model discloses a modular down jacket with a detachable down core, the main purpose of which is to overcome the above-mentioned shortcomings and disadvantages of the existing technology:
[0006] The technical solution adopted in this utility model is as follows:
[0007] A detachable down jacket includes a down inner core and an outer jacket. The down inner core has several first fastening buckles at the collar, back, front center, and bottom. The inner side of the outer jacket has several corresponding first buttons that are movably fastened to the first fastening buckles. A zipper is provided between the shoulder and sleeve of the outer jacket. The down inner core has a second fastening buckle at the shoulder, and the outer jacket has a corresponding second button that is movably fastened to the second fastening buckle. The cuff of the down inner core has a first A-side Velcro, and the inner side of the cuff of the outer jacket has a corresponding first B-side Velcro that is movably fastened to the first A-side Velcro.
[0008] Furthermore, the first fastening buckle and the first button are set in a one-to-one correspondence.
[0009] Furthermore, the second fastening buckle and the second button are set in a one-to-one correspondence.
[0010] Furthermore, the down inner core and the middle section of the sleeves of the outer garment are provided with a second A-side Velcro and a second B-side Velcro for flexible contact.
[0011] Furthermore, the outer side of the jacket is made of windproof fabric.
[0012] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:
[0013] This invention firstly features a zipper at the shoulder of the jacket, allowing the jacket and sleeves to be separated. A second button is also located at the shoulder of the jacket, and a corresponding second fastening buckle is provided at the shoulder of the down filling, increasing the tightness of the jacket and down filling at the shoulder. Next, the jacket sleeves are separated and then slipped onto the down filling sleeves. The first A-side Velcro, the first B-side Velcro, the second A-side Velcro, and the second B-side Velcro further secure the jacket sleeves and down filling sleeves, preventing them from shifting during wear. Finally, first fastening buckles and first buttons are provided at the collar, back, front center, and bottom of the jacket and down filling, ensuring a secure fit at other locations as well. This invention features a novel structure, ingenious design, stylish appearance, and easy disassembly, making it suitable for widespread adoption. Attached Figure Description
