Description

Technical Field

[0001] This utility model relates to the field of clothing, specifically to an easy-to-stretch down jacket. Background Technology

[0002] In the outdoor apparel sector, down jackets are popular among consumers due to their combination of windproof, waterproof, and warm properties. However, existing down jackets have several shortcomings in practical use. On one hand, the sleeve structure of traditional down jackets is relatively fixed. When users perform large-scale stretching, climbing, or carrying movements, the sleeves often become too tight, restricting upper limb movement. This limitation is particularly pronounced in areas with frequent joint movement, such as the shoulders and armpits, significantly impacting comfort and flexibility. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-stretch down jacket. By setting several stretch pads at one end of the sleeve near the main body, the problem of tight sleeves and restricted movement during limb activities is effectively solved.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible down jacket includes a main body, which includes a front panel, a back panel, and a collar. The front panel and the back panel are fixedly connected. The collar is fixedly connected to the upper part of the front panel and the back panel. Sleeves are fixedly connected to both sides of the main body. An extension is provided on one end of the sleeve near the main body. Several extension panels are fixedly connected to the extension. A cuff is provided on one end of the sleeve away from the main body.

[0008] Preferably, the armhole diameter of the extended portion is larger than the armhole diameter of the cuff.

[0009] Preferably, the stretching sheet is elliptical.

[0010] Preferably, the main body and sleeves are composed of a three-layer structure: the outermost layer is a protective layer, the middle layer is a waterproof and breathable membrane layer, and the inner layer is a thermal insulation layer.

[0011] Preferably, the protective layer is made of polyester fiber, and the waterproof and breathable membrane layer is made of polytetrafluoroethylene microporous membrane.

[0012] Preferably, the interior of the insulation layer is filled with down fibers.

[0013] Preferably, a hood is attached to the back of the collar via a zipper, a drawstring is provided on the outside of the hood, and elastic adjustment buckles are installed at the cuffs and the hem of the main body.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a valve plate exhaust assembly with step-by-step locking and axial self-locking, which has the following advantages:

[0016] This flexible down jacket features an extension section near the main body of the sleeve, with several extension panels precisely distributed around the wearer's shoulders and underarms. When the wearer performs large arm movements, these extension panels, thanks to their deformable structure, provide ample room for the sleeve to move, allowing it to extend and deform naturally with arm movements. This significantly reduces the restriction of upper limb movement by the sleeve, allowing for greater freedom of movement. Compared to traditional down jackets, this design effectively solves the problem of tight sleeves restricting movement during limb activities, enabling wearers to perform various movements more freely in outdoor activities and enhancing their overall fitness experience.

[0028] Example 1:

[0029] This embodiment provides a vacuum distillation apparatus for separation and purification, which has the following technical features.

[0030] Please see Figure 1-6 A flexible down jacket includes a main body 1, which includes a front panel 11, a back panel 12, and a collar 13. The front panel 11 and the back panel 12 are fixedly connected. The collar 13 is fixedly connected to the upper part of the front panel 11 and the back panel 12. Sleeves 2 are fixedly connected to both sides of the main body 1. An extension part 21 is provided on one end of the sleeve 2 near the main body 1. Several extension pieces 211 are fixedly connected to the extension part 21. A cuff 22 is provided on one end of the sleeve 2 away from the main body 1.

[0031] It should be noted that, with the stretch pads 211 located on the user's shoulders and underarms, these stretch pads 211 can provide ample room for movement of the sleeves by means of the deformability of their structure when the wearer makes large-scale arm extension or contraction movements.

[0032] In an optional embodiment, the armhole diameter of the extension portion 21 is larger than the armhole diameter of the cuff 22.

[0033] Further design features allow the sleeves to fit snugly against the body, enhancing wearing comfort.

[0034] In an optional embodiment, the stretching sheet 211 is elliptical.

[0035] Furthermore, the stretch pad 211 is located on the wearer's shoulder. Because the stretch pad 211 is oval-shaped, it fits the wearer's shoulder more closely.

[0036] In an optional embodiment, the body 1 and sleeve 2 are composed of a three-layer structure: the outermost layer is a protective layer 3, the middle layer is a waterproof and breathable membrane layer 31, and the inner layer is a thermal insulation layer 32.

[0037] Furthermore, through a tightly integrated three-layer structure with complementary functions, the fabric simultaneously possesses comprehensive properties of waterproofing, windproofing, breathability, and warmth.

[0038] In an optional embodiment, the protective layer 3 is made of polyester fiber, and the waterproof and breathable membrane layer 31 is made of polytetrafluoroethylene microporous membrane.

[0039] Furthermore, the material polyester fiber is subjected to an impregnation-drying-baking coating process to make its protective layer 3 windproof, and a windproof coating is applied to the surface of the protective layer 3 to further enhance the windproof performance of the protective layer 3.

[0040] By using a biaxial stretching process to create a waterproof and breathable membrane with a microporous structure, the waterproof and breathable membrane layer 31 possesses both waterproof and breathable properties. Utilizing the principle of surface tension and molecular size difference in the waterproof and breathable membrane layer 31, it achieves efficient waterproofing while quickly expelling moisture generated by the human body, keeping the wearer dry and comfortable.

[0041] In an optional embodiment, the interior of the insulation layer 32 is filled with down fibers.

[0042] Furthermore, the treated down is evenly filled into the inner fabric, which effectively prevents heat loss and provides efficient and long-lasting warmth.

[0043] In an optional embodiment, a hood 4 is attached to the back of the collar 13 via a zipper, a drawstring 41 is provided on the outside of the hood 4, and elastic adjustment buckles 42 are installed at the cuffs 22 and the hem of the body 1.

[0044] Furthermore, the drawstring 41 on the hat 4 allows the hat 4 to fit snugly against the head in windy and rainy weather, enhancing wind and rain protection. The elastic adjustable buckles 42 at the cuffs 22 and the hem of the main body 1 allow the garment to be flexibly adjusted according to the wearer's actual needs, preventing cold wind and rain from entering and allowing the garment to better fit the body's curves, further improving warmth and wearing comfort.

[0045] Working principle: In use, first sew the front garment piece 11 and the back garment piece 12 together, and then sew the collar 13 onto the front garment piece 11 and the back garment piece 12 to complete the sewing of the main body 1. Then sew the stretch piece 211 onto the upper part of the stretch section 21, and finally sew the stretch section 21 of the sleeve 2 onto both sides of the main body 1 to complete the sewing of the sleeve 2. Because the armhole diameter of the stretch section 21 is larger than the armhole diameter of the cuff 22, it improves the user's wearing comfort. When sewing the stretch piece 211, align the stretch piece 211 with the user's shoulders and armpits to ensure comfortable wear. When the wearer's arms are outstretched, the sleeves can fully release the range of motion. By installing elastic adjustment buckles 42 at both the cuffs 22 and the hem of the main body 1, the tightness of the garment can be flexibly adjusted according to the wearer's actual needs. This not only prevents cold wind and rain from getting in, but also allows the garment to better fit the body's curves, further improving warmth and wearing comfort. When it rains, the hood 4 can be installed on one side of the collar 13 via a zipper. By pulling the drawstring 41 on the hood 4, the hood 4 can be made to fit snugly against the user's head, thereby enhancing the windproof and rainproof effect of the hood 4.

[0046] In summary, this flexible down jacket features an extension section 21 at one end of the sleeve 2 near the main body 1, with several extension panels 211 fixedly connected to it. These extension panels 211 are precisely distributed in the user's shoulder and armpit areas, allowing the sleeve 2 to provide ample room for movement when the wearer performs large-scale arm extension or retraction movements. This enables the sleeve 2 to naturally extend and flexibly deform with arm movements, significantly reducing the restriction of upper limb movement and fully releasing the range of motion. Compared to traditional down jackets, this design effectively solves the problem of tight sleeves restricting movement during limb activities, allowing the wearer to perform various movements more freely in outdoor activities and enhancing the sports experience.
