Description

Technical Field

[0001] The invention belongs to the technical field of down jackets, and in particular relates to an inner liner structure of a down jacket that is capable of keeping warm and locking down down. Background Art

[0002] The principle of down jackets to keep warm is that there are gaps between the down, which fix a certain amount of air. Because the gaps are small, the air convection between them is poor, making it difficult for the cold air outside to reach the inside, and conversely, it is difficult for the hot air inside to get out, so that the temperature is maintained.

[0003] In order to prevent down from running out and penetrating, existing down jackets use adhesive strips to separate the filling areas instead of traditional stringers. However, adhesive strip bonding has the following disadvantages: the gaps between the down at the bonding points are small, which causes the temperature at the bonding points to lose temperature quickly; and the adhesive strips at the bonding points are easily debonded and fall off after washing and rubbing, causing down to fall out. Summary of the Invention

[0004] The purpose of the present invention is to provide a liner structure for a down jacket that is warm and down-locking in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A liner structure for a warm, down-locking down jacket comprises a liner. The liner and inner and outer layers of fabric together form a down jacket body. Vertical airbags are provided on both sides of the down jacket body near a zipper. An inflation structure and a vacuum structure respectively connected to the two vertical airbags are provided at the hem of the down jacket body. A horizontal airbag connected to the vertical airbags is provided inside the liner. The side surfaces of the horizontal airbags are bonded to the inner wall of the liner. A plurality of ventilation structures opened by increasing the pressure difference are provided on the upper and lower surfaces of the horizontal airbags.

[0007] As a further optimization solution of the present invention, the interior of the liner is divided into a plurality of transverse down filling cavities by transverse airbags. The function of the down filling cavities is to accommodate and fix the down, thereby locking the down.

[0008] As a further optimization scheme of the present invention, the inner surface of the transverse airbag is provided with several groups of convex card blocks and concave card blocks for positioning. The convex card blocks and concave card blocks are connected to the transverse airbag by bonding. The purpose of providing the convex card blocks and concave card blocks is to prevent the transverse airbag from being misplaced during the inflation and deflation process, and to facilitate alignment.

[0009] As a further optimization scheme of the present invention, the outer wall of the transverse airbag is provided with an adhesive that is bonded to the inside of the inner liner. The position of the adhesive corresponds to the convex card block and the concave card block. The contact surface between the transverse airbag and the inner wall of the liner is also provided with a number of arc-shaped rubber strips arranged in a fish scale shape. The main function of the adhesive is to fix the transverse airbag, and the arc-shaped rubber strips are used to lock the velvet. Setting it in a fish scale shape improves the rubber strip's anti-rubbing ability to prevent it from coming apart during cleaning.

[0010] As a further optimization scheme of the present invention, the inner wall surface of the transverse airbag is provided with an elastic skeleton that makes the cross-section of the transverse airbag elliptical or quasi-elliptical. The elastic skeleton is provided so that the transverse airbag has the ability to evacuate air when under negative pressure, and can extract gas into the filling cavity to achieve the purpose of compression of the filling cavity. It can reduce the volume during cleaning, enhance the connection between the inner and outer layers, reduce the kneading force, and protect the adhesive.

[0011] As a further optimization scheme of the present invention, the ventilation structure includes several hollow cylinders that are arranged through the surface of the horizontal airbag, a flange is provided at the inner center of the hollow cylinder, a valve block is slidably connected to the center of the flange, and both ends of the valve block are provided with springs for keeping the valve block overlapped with the flange, and a valve stem for guiding the valve block, and both ends of the hollow cylinder are provided with air ports.

[0012] As a further optimization solution of the present invention, a filter is provided inside the air port to prevent the fluff from entering the hollow cylinder.

[0013] As a further optimization scheme of the present invention, the inflation structure includes an inflatable bag arranged on the inner side of the fabric at the hem of the down jacket body, a return spring is arranged inside the inflatable bag, and two one-way valves are arranged on the surface of the inflatable bag, one of the one-way valves is connected to the atmosphere for sucking air into the inflatable bag, and the other one-way valve is connected to the vertical air bag for inflating the vertical air bag. The exhaust structure has the same structure as the inflation structure, and the one-way valves are in opposite directions. The inflation structure and the exhaust structure are arranged for inflating or deflating the horizontal air bag.

[0014] The beneficial effects of the present invention are:

[0015] The present invention replaces the traditional truss stitching with a transverse airbag, so that the transverse airbag can be inflated, making the thickness of the down jacket uniform and improving the thermal insulation capacity of the separated area. A ventilation structure opened by a pressure difference is also provided between the transverse airbag and the filling cavity, so that the transverse airbag can inflate and evacuate the filling cavity. The exhaust causes the inner liner to shrink, which can reduce the degree of rubbing of the inner liner during cleaning and protect the adhesive between the transverse airbag and the inner liner, thereby improving the down locking ability of the transverse airbag.

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-6 As shown, a liner structure of a warm and down-locking down jacket includes a liner 3. The liner 3 and the inner and outer layers of fabric 2 together form a down jacket body 1. Vertical air bags 42 are provided on both sides of the down jacket body 1 near the zipper. An inflation structure 6 and an air extraction structure 7 respectively connected to the two vertical air bags 42 are provided at the hem of the down jacket body 1. A horizontal air bag 41 connected to the vertical air bag 42 is provided inside the liner 3. The side surface of the horizontal air bag 41 is bonded to the inner wall of the liner 3. The upper and lower surfaces of the horizontal air bag 41 are provided with a plurality of ventilation structures 5 that are opened by increasing the pressure difference.

[0026] The partition area 32 of the traditional down jacket liner 3 is separated by girder lines. The holes in the girder stitching area are easy to be drilled with down. The use of colloidal bonding has poor air fixation ability in the partition area 32, resulting in poor warmth retention in this area. However, by replacing the traditional girder stitching with the transverse airbag 41, the transverse airbag 41 can be inflated to improve the warmth retention capacity of the partition area 32. Furthermore, in order to improve the ability to fix air, a certain amount of down can also be filled inside the transverse airbag 41.

[0027] The interior of the liner 3 is divided into a plurality of transverse filling cavities 31 by the transverse airbags 41 , and the filling areas 31 can also be divided vertically as needed.

[0028] In order to improve the lint-locking ability of the connection between the transverse airbag 41 and the inner liner 3, and to improve its anti-rubbing ability during cleaning, the transverse airbag 41 and the inner liner 3 are fixed by adhesive 43, and the inner surface of the transverse airbag 41 is provided with several groups of convex blocks 44 and concave blocks 45 for positioning. The convex blocks 44 and the concave blocks 45 are connected to the transverse airbag 41 by bonding, and the outer wall of the transverse airbag 41 is provided with adhesive 43 that is bonded to the inside of the inner liner 3. The position of the adhesive 43 corresponds to the convex blocks 44 and the concave blocks 45. The contact surface between the transverse airbag 41 and the inner wall of the inner liner 3 is also provided with several arc-shaped rubber strips 47 arranged in a fish scale shape.

[0029] The purpose of setting the convex block 44 / concave block 45 is to make the transverse airbag 41 dock and fit together when inflating and deflated, so as to prevent the inner and outer surfaces of the inner liner 3 from being misaligned due to placement, and the convex block 44 / concave block 45 can serve as the back plate of the adhesive 43. The position of the adhesive 43 corresponds to the position of the convex block 44 / concave block 45, which can prevent the adhesive 43 from constantly deforming when rubbed, and reduce the probability of degumming to a certain extent. Furthermore, in order to increase the firmness of the connection between the transverse airbag 41 and the inner liner 3, the transverse airbag 41 can set stitches on the back of the convex block 44 / concave block 45 to reinforce the connection between the transverse airbag 41 and the inner liner 3. Since the adhesive 43 is covered there, the pinhole will not be pulled larger to cause lint.

[0030] Since the horizontal airbag 41 and the inner liner 3 cannot be separated by the adhesive 43 alone, the down filling cavity 31 will be caused to fall into the down filling cavity 31 below. Therefore, an arc-shaped adhesive strip 47 is provided at the gap of the adhesive 43. Figure 6 As shown, the arc-shaped rubber strip 47 does not need to play a fixing role, but only needs to satisfy the function of separating the filling cavity 31. Therefore, it is set to be thinner and arranged in a fish-scale shape to increase its anti-rubbing ability during cleaning.

[0031] In order to make the transverse airbag 41 have negative pressure when it shrinks and prevent the transverse airbag 41 from being completely sucked flat, the inner wall surface of the transverse airbag 41 is provided with an elastic skeleton 46 that makes the cross-section of the transverse airbag 41 elliptical or quasi-elliptical. In conjunction with the ventilation structure 5, it is possible to inflate and exhaust air into the filling cavity 31. The ventilation structure 5 includes a plurality of hollow cylinders 51 that are arranged through the surface of the transverse airbag 41. A flange 53 is provided at the inner center of the hollow cylinder 51. A valve block 54 is slidably connected at the center of the flange 53. Both ends of the valve block 54 are provided with a spring 56 for keeping the valve block 54 overlapped with the flange 53, and a valve stem 55 for guiding the valve block 54. Both ends of the hollow cylinder 51 are provided with an air port 52.

[0032] The ventilation structure 5 is provided so that the positive and negative pressures generated in the transverse airbag 41 can be transmitted to the filling cavity 31, especially when washing the down jacket, so that negative pressure is generated, the air in the filling cavity 31 is extracted, and the inner and outer layers are pressed against each other and contracted. During washing, after the inner and outer layers of the liner 3 are tightened, the friction force exerted on the inner and outer layers causes them to move forward and backward together, and no or less force is generated to tear the adhesive 43.

[0033] In order to solve the problem of lint in the air port 52 , a filter is provided inside the air port 52 .

[0034] The inflatable structure 6 includes an inflatable bag 61 disposed on the inner side of the fabric 2 at the hem of the down jacket body 1. A return spring 62 is disposed inside the inflatable bag 61. Two one-way valves 63 are disposed on the surface of the inflatable bag 61. One of the one-way valves 63 is connected to the atmosphere for sucking air into the inflatable bag 61, and the other one-way valve 63 is connected to the vertical air bag 42 for inflating the vertical air bag 42. The exhaust structure 7 has the same structure as the inflatable structure 6, but the one-way valves 63 are in opposite directions. The function of the inflatable structure 6 is to artificially inflate the horizontal air bag 41. The parts where the inflatable bag 61 and the exhaust structure 7 are connected to the outside atmosphere can be capped to prevent mutual influence.

[0035] When inflation is needed, open the cap of the inflatable structure 6, repeatedly squeeze and press the inflatable bag 61 to fill the vertical air bag 42 and the transverse air bag 41 with air. After the gas pressure of the transverse air bag 41 is sufficient to push the spring 56, continue to inflate the filling cavity 31. When exhaust is needed, close the cap of the entrance of the inflatable structure 6, open the cap of the exhaust structure 7, and repeatedly squeeze and press to extract the gas in the transverse air bag 41. Among them, the transverse air bag 41 is restricted by the spring frame 46 after shrinkage and will not be flattened. Therefore, negative pressure is generated inside the transverse air bag 41, and the negative pressure pushes open the valve block 54 to extract the air in the filling cavity 31, which is convenient for cleaning. The warmth effect of the down jacket can also be adjusted by inflation and deflation. It should be noted that an elastic frame 46 is also required to be provided inside the vertical air bag 42 connected to the exhaust structure 7 to prevent it from being sucked flat.

[0036] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
