Description

Technical Field

[0001] This invention relates to the field of down jacket technology, and in particular to a down jacket with breathable zones. Background Technology

[0002] Current down jackets are filled with down in all four panels (left, right, and back) to enhance warmth. However, because the entire jacket is filled with down, the trapped air inside makes it difficult to pack and store, hindering the process. Therefore, it is necessary to design a down jacket that is both warm and easy to pack. Summary of the Invention

[0003] The main objective of this invention is to provide a down jacket with breathable zones.

[0004] The down jacket with breathable zones proposed in this invention includes: a back piece, a left piece, and a right piece. The left and right pieces are sewn to the back piece. Each of the left, right, and back pieces contains an inner lining layer, an outer fabric layer, and down filling the space between the inner lining layer and the outer fabric layer. The inner lining layer and the outer fabric layer of the left piece have several left-piece connecting lines, and the inner lining layer and the outer fabric layer of the right piece have several right-piece connecting lines. The inner lining layer and the outer fabric layer between adjacent left-piece connecting lines form a left-piece filling cavity, and the inner lining layer and the outer fabric layer between adjacent right-piece connecting lines form a right-piece filling cavity. Both the left-piece filling cavity and the right-piece filling cavity are filled with down. The back piece has several back-piece connecting lines between its inner lining layer and the outer fabric layer. A portion of the inner lining layer and the outer fabric layer between adjacent back-piece connecting lines form a back-piece filling cavity, which is filled with down. A portion of the inner lining layer and the outer fabric layer between adjacent back-piece connecting lines form a breathable zone. The breathability of the breathable zone is higher than that of the back-piece filling cavity.

[0005] Furthermore, a mesh-like or porous breathable fabric layer is provided on the inner layer corresponding to the breathable area.

[0006] Furthermore, the back panel filling cavity includes a plurality of first back panel filling cavities, which are formed between the inner layer and the surface layer between adjacent back panel connecting lines in the upper half of the back panel. The first back panel filling cavities are arranged adjacent to each other, and the first back panel filling cavities are filled with down.

[0007] Furthermore, the back panel filling cavity also includes several second back panel filling cavities. The second back panel filling cavities and the ventilation area are both located in the lower half of the back panel, and the second back panel filling cavities and the ventilation area are alternately arranged. A portion of the inner layer and the surface layer between the back panel connecting lines in the lower half of the back panel form the second back panel filling cavity, which is filled with down. A portion of the inner layer and the surface layer between the back panel connecting lines in the lower half of the back panel form the ventilation area. A ventilation area is provided between the first back panel filling cavity and the second back panel filling cavity.

[0008] Furthermore, the width of the inner layer between the adjacent back sheet connecting lines corresponding to the second back sheet filling cavity is D1, the width of the surface layer is D2, and the widths of the two ventilated areas adjacent to the second back sheet filling cavity are D3 and D4, where D1≥D2+n*(D3+D4), and n is greater than 1.

[0009] Furthermore, the lower half of the back piece also includes a bottom area, and the down filling cavity of the back piece also includes at least two adjacent third back piece filling cavities. The third back piece filling cavity is located in the bottom area, and the inner layer and the surface layer between the adjacent back piece connecting lines in the bottom area form the third back piece filling cavity. Down is filled in the third back piece filling cavity, and a breathable area is provided between the third back piece filling cavity and the second back piece filling cavity.

[0010] Furthermore, there is a filling material between the inner layer and the outer layer corresponding to the breathable area, and the weight of the filling material is less than the weight of the down filling the back panel cavity.

[0011] Furthermore, the connecting lines for the left, right, and rear panels are either seams or adhesive tape.

[0012] The technical solution of this invention has the following advantages over the prior art:

[0013] The left and right filling cavities of the down jacket with a breathable area in this invention are arranged adjacent to each other and are both filled with down. The back piece includes a back filling cavity and a breathable area. This arrangement can achieve warmth and also allow the air in the down jacket to be quickly expelled through the breathable area, making it easy to store. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] The down jacket with a breathable area in this embodiment of the invention includes a back piece 1, a left piece 2, and a back piece 3. The left piece 2 and the right piece 3 are sewn to the back piece 1 to form the down jacket. The left piece 2, the right piece 3, and the back piece 1 each contain an inner layer 4, an outer fabric layer 5, and down filling the space between the inner layer 4 and the outer fabric layer 5. The inner layer 4 and the outer fabric layer 5 of the left piece 2 have a plurality of left piece connecting lines 21, and the inner layer 4 and the outer fabric layer 5 of the right piece 3 have a plurality of right piece connecting lines 31. The inner layer 4 and the outer fabric layer 5 between adjacent left piece connecting lines 21 form a left piece filling cavity 22, and adjacent right pieces are connected... The inner layer 4 and the surface layer 5 between the threads 31 form the right piece filling cavity 32. The left piece filling cavity 22 and the right piece filling cavity 23 are both filled with down. Several back piece connecting threads 11 are provided between the inner layer 4 and the fabric layer 5 of the back piece 1. The inner layer 4 and the surface layer 5 between some adjacent back piece connecting threads 11 form the back piece filling cavity 12, which is filled with down. The inner layer 4 and the surface layer 5 between some adjacent back piece connecting threads 11 form a breathable area 13, which has higher breathability than the back piece filling cavity 12.

[0024] Since the left and right pieces 2 and 3 are connected by the left connecting line 21 and the right connecting line 31, respectively, corresponding left filling cavity 22 and right filling cavity 32 are formed between them and filled with down, and a back filling cavity 12 filled with right down is set in a part of the back piece 1, and a breathable area 13 is set in another part, it can achieve both warmth and breathability, and is convenient for storage.

[0025] Preferably, a mesh-like or porous breathable fabric layer is provided on the inner layer 4 corresponding to the breathable area 13 to increase breathability.

[0026] Preferably, the back panel filling cavity 12 includes a plurality of first back panel filling cavities 121. The inner layer 4 and the surface layer 5 located between adjacent back panel connecting lines 11 in the upper half of the back panel 1 form the first back panel filling cavity 121. The first back panel filling cavities 121 are arranged adjacent to each other. The first back panel filling cavities 121 are filled with down. The first back panel filling cavities 121 are located between the back panel connecting lines 11 in the upper half of the back panel 1. The first back panel filling cavities 121 are filled with down, which can ensure the warmth of the upper back part of the customer who is more afraid of cold and is prone to wind.

[0027] Preferably, the back panel filling cavity 12 further includes a plurality of second back panel filling cavities 122. Both the second back panel filling cavities 122 and the breathable area 13 are located in the lower half of the back panel 1, and the second back panel filling cavities 122 and the breathable area 13 are alternately arranged. A portion of the second back panel filling cavity 122 is formed between the inner layer 4 and the surface layer 5 between the back panel connecting lines 11 in the lower half of the back panel 1. The second back panel filling cavity 122 is filled with down. A portion of the breathable area 13 is formed between the inner layer 4 and the surface layer 5 between the back panel connecting lines 11 in the lower half of the back panel 1. A breathable area 13 is provided between the first back panel filling cavity 121 and the second back panel filling cavity. Thus, by intermittently providing the second filling cavity 122 and the breathable area 13 in the lower half of the back panel 1, both warmth and breathability of the customer's cold-resistant lower back can be ensured.

[0028] Preferably, the width of the inner layer between the adjacent back panel connecting lines 11 of the second back panel filling cavity 122 is D1, the width of the surface layer is D2, and the widths of the two adjacent ventilation zones 13 are D3 and D4, where D1 ≥ D2 + n*(D3 + D4), and n is greater than 1. This arrangement ensures that even when the customer wears a down jacket, the down in the second filling cavity 122 will cover the ventilation zones 13. Therefore, when wearing a down jacket, the ventilation zones 13 will also have down for warmth. When packing the down jacket, the air in the down jacket can be quickly expelled through the ventilation zones 13, making it convenient for packing and storage.

[0029] Preferably, the lower half of the back panel 1 further includes a bottom area 14, and the down filling cavity 12 of the back panel also includes at least two adjacent third back panel filling cavities 123. The third back panel filling cavities 123 are located in the bottom area 14, and the inner layer 4 and the surface layer 5 located between the adjacent back panel connecting lines 11 in the bottom area 14 form the third back panel filling cavity 123. The third back panel filling cavity 123 is filled with down, and a breathable area 13 is provided between the third back panel filling cavity 123 and the second back panel filling cavity 122. This arrangement can ensure the warmth and windproofness of the bottom area 14 of the down jacket, and improve the warmth retention effect.

[0030] Preferably, there is a filling material between the inner layer 4 and the surface layer 5 corresponding to the breathable zone 13. The weight of the filling material is less than the weight of the down filling the back filling cavities 121, 122, and 123, so that the warmth and breathability of the breathable zone 13 can be balanced.

[0031] Preferably, the left piece connecting line 21, the right piece connecting line 31, and the rear piece connecting line 11 are seams or adhesive lines, which facilitates processing and production.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
