Description

Technical Field

[0001] This utility model patent relates to the technical field of down jackets, and in particular to a lightweight down jacket. Background Technology

[0002] Down jackets typically use low-elasticity fabrics for both the outer and inner lining to prevent the down filling from accumulating due to repeated deformation, which could lead to uneven thickness and reduced warmth. Therefore, existing down jackets have limited stretchability; even with pre-set allowances in the outer and inner lining, the thickness of the filling can still cause significant restriction when the wearer moves (such as raising arms, bending over, etc.). Utility Model Content

[0003] The purpose of this utility model is to solve the existing technical problems by proposing a lightweight down jacket.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight down jacket, comprising a body, the body comprising an outer layer and an inner layer, with an insulating layer or stretch garment piece sandwiched between the outer layer and the inner layer, and a fixing seam thread passing through the edge of the stretch garment piece, between the outer layer and the inner layer to form a first stitch, the first stitch being completely or openly enclosing to form a stretch area; both the outer layer and the inner layer of the stretch area have stretch allowance.

[0005] Preferably, the insulation layer includes a first lining, an insulation material, and a second lining, with the insulation material filling the space between the first lining and the second lining.

[0006] Preferably, the insulation layer is down filling the space between the outer and inner layers.

[0007] Preferably, the main body includes a front piece, a back piece, and sleeves that are sewn together, with stretch garment pieces arranged around the armholes of the main body.

[0008] Preferably, the main body includes a front piece and a back piece joined by seams, and the stretch garment piece is set to cover the side seam of the front piece or the side seam of the back piece.

[0009] Preferably, the stretch garment piece is cut from an elastic fabric.

[0010] Preferably, the width of the stretch garment piece is 2-5cm.

[0011] Preferably, the surface layer is cut from 10D lightweight fabric.

[0012] The beneficial effects of this utility model are: by expanding the stretch of the down jacket through the stretching piece, the feeling of restriction on the human body is reduced; the stretching piece is sandwiched between the outer layer and the inner layer, so as not to affect the uniform expression of the outer surface of the body; the stretching setting provides a buffer for the insulation layer, and avoids excessive stretching of the insulation layer outside the stretching area.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In conjunction with the embodiments and appendices Figure 1-4 A lightweight down jacket includes a body 1, which includes an outer layer 11 and an inner layer 12. An insulating layer or stretchable garment piece 14 is sandwiched between the outer layer 11 and the inner layer 12. Fixed seams are threaded through the edge of the stretchable garment piece and between the outer layer 11 and the inner layer 12 to form a stretchable area 21. Both the stretchable outer layer 110 and the stretchable inner layer 120 have stretch allowance 4, so that the stretchable outer layer 110 forms wrinkles in the unstretched state, and the wrinkles can be flattened when the wearer stretches during movement. The number of stretchable garment pieces 14 is not less than one.

[0016] Furthermore, a fixing thread is threaded between the edge of the stretched garment piece, the outer layer, and the inner layer to form a first stitch 31. The first stitch 31 completely or openly encloses the stretching area 21, which can be ring-shaped, U-shaped, or strip-shaped.

[0017] A lightweight down jacket has an insulation layer comprising a first lining, an insulation material, and a second lining, with the insulation material filling the space between the first and second linings. Quilted seams are threaded between the outer layer, the first lining, the second lining, and the inner layer, forming several down-filling cavities 13 for filling with the insulation material, which is down or a down-containing mixture.

[0018] Furthermore, the thermal insulation seam is threaded between the outer layer 11, the thermal insulation layer and the inner layer 12 to form a second stitch 32. The second stitch is used to fix the edge of the thermal insulation layer and is set along the edge of the stretching area 21.

[0019] Furthermore, when the stretch garment piece 14 is independently sandwiched between the outer layer 11 and the inner layer 12, the stretch garment piece 14 is not connected to the first lining fabric and the second lining fabric, thereby reducing the impact of the deformation of the stretch garment piece on the filling cavity.

[0020] A lightweight down jacket has a thermal insulation layer made of down filling between an outer layer 11 and an inner layer 12. The lining-less design makes the overall body lightweight. Thermal insulation seams are threaded between the outer layer 11 and the inner layer 12 to form a second stitch 32. A buffer gap is left between the first stitch 31 and the second stitch 32. The second stitch 32 is located outside the stretching area. The side of the second stitch 32 away from the stretching area 21 is the thermal insulation area 22. By setting the buffer gap, the influence of the stretching garment piece on the deformation of the down filling in the thermal insulation area is reduced.

[0021] A lightweight down jacket has a main body 1 consisting of a front piece, a back piece, and sleeves that are sewn together. A stretchable garment piece 14 is set around the sleeve opening of the main body to form a ring stretchable area, providing sufficient stretch for the sleeve connection and facilitating the wearer's movement. At the same time, the sleeve opening of the main body has no filling material, making it thinner relative to the warm area and reducing obstacles in the sleeve splicing process. It is suitable for styles with sleeves.

[0022] Furthermore, when the sleeves are divided into upper and lower sleeve pieces, the stretching pieces can be set along the opening curve of the upper or lower sleeve piece to form a U-shaped stretching area.

[0023] A lightweight down jacket includes a front and back panel connected by seams, with a stretchable garment piece 14 covering the side seam of the front panel or the side seam of the back panel; the stretchable garment piece 14 may also be set along the weft direction on the front panel and / or the back panel to form a strip stretch area, which facilitates bending and stretching movements, and can be used in sleeved styles or sleeveless vests.

[0024] Furthermore, the stretch garment piece 14 is cut from an elastic fabric, which can be selected from elastic thermal polyester fabric or nylon four-way stretch fabric; the elastic fabric is blended with self-heating fibers.

[0025] Furthermore, the width of the stretch garment piece 14 is 2-5cm, and the area of ​​the stretching zone surface layer 110 and the stretching zone inner layer 120 is 120-200% of the area of ​​the stretch garment piece.

[0026] A lightweight down jacket with an outer layer made of 10D lightweight fabric cut and shaped.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
