Description

Technical Field

[0001] This invention relates to the field of down jackets, and more specifically to a children's down jacket with adjustable loft. Background Technology

[0002] Down jackets are excellent winter clothing. The fluffy down in the inner lining forms countless tiny air chambers, trapping a large amount of air and thus blocking heat transfer. The loft of the down is directly proportional to its warmth retention to a certain extent, but the fluffier the down jacket, the more bulky it becomes.

[0003] For children's down jackets, due to the proportions of children's bodies (the length of their limbs and torso is smaller), the bulkiness of down jackets can greatly affect children's flexibility. Existing children's down jackets lack adjustable loft, so they cannot be flexibly adjusted for different insulation needs, such as indoor and outdoor environments. Summary of the Invention

[0004] The purpose of this invention is to provide a children's down jacket with adjustable loft, which solves the problem that the loft of existing children's down jackets cannot be flexibly adjusted.

[0005] The present invention achieves the above objectives through the following technical solutions: A down jacket with adjustable loft for children includes a down jacket body, which includes an outer fabric, a lining and an inner lining, and also includes an adjustment component. The adjustment component includes a flexible adsorption layer attached to the inner side of the inner lining and a base fabric for attaching to the outer side of the inner lining. The base fabric is provided with multiple flexible magnetic adsorption sections for adsorbing with the flexible adsorption layer to adjust the loft of the inner lining. The flexible magnetic part is folded along with the base fabric and set in the quilted area at the connection of the inner liner. One end of the base fabric is fixed to the quilt, and the other end is connected to a traction rope, which is used to pull the folded base fabric upward to fit against the inner liner and attract each other to the flexible adsorption layer.

[0006] In a preferred embodiment of the present invention, each base fabric is connected to a traction rope on both sides by a connecting rope, and each pair of traction ropes connects several base fabrics vertically. The bottom end of the traction rope is connected to the hem of the down jacket body, and the other end passes through the shoulder to the outside of the down jacket body for pulling. This embodiment uses a pair of traction ropes to pull the two sides of the base fabric, and each pair of traction ropes pulls multiple base fabrics simultaneously in its extension direction. Each base fabric corresponds to an inner lining. The traction rope can simultaneously unfold multiple base fabrics to cover multiple inner linings in the extension direction.

[0007] As a preferred embodiment of the present invention, the quilting of the outer fabric and the inner lining forms a folded cavity to accommodate the folded base fabric. This embodiment places the folded base fabric inside the folded cavity, which can not only make up for the problem of weak insulation in the quilted area, but also effectively reduce the bulge or foreign body feeling caused by the folded base fabric.

[0008] As a preferred embodiment of the present invention, a connecting part is provided at the end of the base fabric away from the connecting rope, and the connecting part is fixedly connected to the quilting by a sewing part. In this embodiment, the connecting part allows one end of the base fabric to be sewn to the quilting of the inner lining, so that the base fabric covers the surface of the inner lining after unfolding.

[0009] In a preferred embodiment of the present invention, a through loop is provided on the shoulder of the down jacket body, and the upper end of the traction rope extends through the through loop to the outside of the down jacket body. A movable fixing buckle is provided on the extended end of the traction rope. The movable fixing buckle is slidably connected to the traction rope and has a pressing structure. When the movable fixing buckle abuts against the through loop, it prevents the traction rope from falling. This embodiment can fix the traction rope by setting the movable fixing buckle. The movable fixing buckle is slidably connected to the traction rope and can press the traction rope to fix it.

[0010] As a preferred embodiment of the present invention, the flexible magnetic attraction part is formed by hot pressing a mixture of magnetic powder and adhesive, and the flexible adsorption layer is formed by hot pressing a mixture of metal powder that can be attracted by the magnetic powder and adhesive. This embodiment specifically provides a flexible magnetic attraction part, which is formed by mixing magnetic powder and adhesive and hot pressing it onto a base fabric, or by using it as an adhesive layer to bond two layers of fabric into a base fabric. This makes the magnetic attraction part more flexible and can be used in clothing. This flexible magnetic attraction part can effectively prevent the magnetic powder from being corroded. The metal powder can be iron powder, and the adhesive can effectively prevent the iron powder from rusting.

[0011] In a preferred embodiment of the present invention, when the base fabric is folded, adjacent flexible magnetic parts attract and adhere to each other. The surface of the base fabric that contacts the inner lining is also provided with a smooth coating so that it can automatically fall and fold when the traction rope loses its traction. This solution folds by making adjacent flexible magnetic parts attract each other. When the down jacket needs to be fluffy, the smooth coating can prevent the base fabric from adhering to the inner lining by friction. Releasing the traction rope will cause the base fabric to slip off and refold by the magnetic force between adjacent flexible magnetic parts.

[0012] In a preferred embodiment of the present invention, the number of flexible magnetic accommodating parts on each of the base fabrics is even. When the base fabric is flattened upwards, the magnetic force of the flexible magnetic accommodating parts increases sequentially from top to bottom. This allows the flexible magnetic accommodating parts that attract each other during the upward pulling of the traction rope to unfold sequentially from the end with the weakest magnetic force. This solution has multiple adjustment levels. Since the lining of a down jacket generally sheds down spontaneously, the bottom of the lining is actually wider and requires stronger magnetic force. Therefore, when the flexible magnetic accommodating parts are fully flattened upwards, the magnetic attraction increases from top to bottom, making the magnetic attraction force more balanced. When the traction rope is pulled upwards, the flexible magnetic accommodating parts can also unfold one by one. This allows for compression from the thicker area below the lining, resulting in uniform loft for the same lining. As more flexible magnetic accommodating parts unfold, the pressure level on the lining increases sequentially, achieving the function of multi-level adjustment of loft.

[0013] The beneficial effects of the present invention are as follows: The present invention provides a foldable and unfoldable flexible magnetic part between the outer fabric and the lining, and provides a flexible adsorption layer corresponding to the flexible magnetic part on the opposite side of the inner lining, so that the fluffiness of the inner lining can be compressed and reduced. The magnetic adjustment method does not penetrate the inner lining, avoids down leakage, and allows the fluffiness to be adjusted as needed to flexibly adapt to the activity needs of children.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0016] like Figure 1-5 As shown, a down jacket with adjustable loft for children includes a down jacket body 1, which includes an outer fabric 11, a lining 12 and an inner lining 13, and also includes an adjustment component 2. The adjustment component 2 includes a flexible adsorption layer 25 that adheres to the inside of the inner lining 13 and a base fabric 21 that adheres to the outside of the inner lining 13. The base fabric 21 is provided with multiple flexible magnetic adsorption parts 22, which are used to adsorb with the flexible adsorption layer 25 to adjust the loft of the inner lining 13. The flexible magnetic part 22 is folded along with the base fabric 21 and disposed in the quilting 14 area at the connection of the inner liner 13. One end of the base fabric 21 is fixed to the quilting 14, and the other end is connected to a traction rope 27, which is used to pull the folded base fabric 21 upward to adhere to the inner liner 13 and attract each other to the flexible adsorption layer 25.

[0017] This solution provides a foldable and unfoldable flexible magnetic part 22 between the outer fabric 11 and the inner fabric 12, and a flexible adsorption layer 25 corresponding to the flexible magnetic part 22 on the opposite side of the inner lining 13. This allows the fluffiness of the inner lining 13 to be compressed and reduced. The magnetic adjustment method does not penetrate the inner lining 13, preventing down leakage. This allows the fluffiness to be adjusted as needed, flexibly adapting to the activity needs of children.

[0018] Specifically, by pulling the traction rope 27, the folded base fabric 21 is unfolded upwards, and the flexible magnetic part 22 is attached to the outer surface of the inner liner 13, attracting each other with the flexible adsorption layer 25 on the inner side of the inner liner 13 and pressing the inner liner 13 tightly.

[0019] Preferably, both sides of each base fabric 21 are connected to the traction rope 27 via connecting rope 26, and each pair of traction ropes 27 connects several base fabrics 21 vertically. The bottom end of the traction rope 27 is connected to the hem of the down jacket body 1, and the other end passes through from the shoulder to the outside of the down jacket body 1 for pulling. This solution sets a pair of traction ropes 27 to pull the two sides of the base fabric 21, and each pair of traction ropes 27 pulls multiple base fabrics 21 simultaneously in its extension direction. Each base fabric 21 corresponds to an inner lining 13. The traction rope 27 can simultaneously unfold multiple base fabrics 21 to cover multiple inner linings 13 in the extension direction.

[0020] Preferably, the quilting 14 of the outer fabric 11 and the inner lining 13 forms a folding cavity 15 to accommodate the folded base fabric 21. This solution places the folded base fabric 21 inside the folding cavity 15, which can not only make up for the problem of weak insulation in the quilting 14 area, but also effectively reduce the bulge or foreign body feeling caused by the folded base fabric 21.

[0021] Optionally, the base fabric 21 is provided with a connecting part 23 at the end away from the connecting rope 26. The connecting part 23 is fixedly connected to the quilting 14 by a sewing part 24. In this solution, the connecting part allows one end of the base fabric 21 to be sewn to the quilting 14 of the inner liner 13, so that the base fabric 21 covers the surface of the inner liner 13 after unfolding.

[0022] Preferably, a through loop 16 is provided on the shoulder of the down jacket body 1, and the upper end of the traction rope 27 extends to the outside of the down jacket body 1 through the through loop 16. A movable fixing buckle 28 is provided on the extended end of the traction rope 27. The movable fixing buckle 28 is slidably connected to the traction rope 27 and has a pressing structure. When the movable fixing buckle 28 abuts against the through loop 16, it prevents the traction rope 27 from falling. This solution can fix the traction rope 27 by setting the movable fixing buckle 28. The movable fixing buckle 28 is slidably connected to the traction rope 27, and the movable fixing buckle 28 can press the traction rope 27 to fix it.

[0023] Preferably, the flexible magnetic attraction part 22 is formed by hot pressing a mixture of magnetic powder and adhesive, and the flexible adsorption layer 25 is formed by hot pressing a mixture of metal powder that can be attracted by the magnetic powder and adhesive. This solution specifically provides a flexible magnetic attraction part 22, which is formed by mixing magnetic powder and adhesive and hot pressing it onto the base fabric 21, or by using the mixed adhesive as an adhesive layer to bond two layers of fabric into the base fabric 21. This makes the magnetic attraction part more flexible and can be used in clothing. This flexible magnetic attraction part 22 can effectively prevent the magnetic powder from being corroded. The metal powder can be iron powder, and the adhesive can effectively prevent the iron powder from rusting. Before bonding, an external magnetic field is applied to orient the magnetic powder particles to determine the polarity.

[0024] Preferably, when the base fabric 21 is folded, the adjacent flexible magnetic parts 22 attract and adhere to each other. The surface of the base fabric 21 that contacts the inner lining 13 is also provided with a smooth coating so that it can automatically fall and fold when the traction rope 27 loses its traction. This solution folds by making the adjacent flexible magnetic parts 22 attract each other. When the down jacket needs to be fluffy, the smooth coating can prevent the base fabric 21 from adhering to the inner lining by friction. Releasing the traction rope 27 will cause the base fabric 21 to slip off and refold by the magnetic force between the adjacent flexible magnetic parts 22.

[0025] Preferably, the number of flexible magnetic absorbing parts 22 on each base fabric 21 is even. When the base fabric 21 is flattened upwards, the magnetic force of the flexible magnetic absorbing parts 22 increases sequentially from top to bottom, so that the flexible magnetic absorbing parts 22 that attract each other during the upward pulling of the traction rope 27 unfold sequentially from the end with the weakest magnetic force.

[0026] This design incorporates multiple adjustment levels. Since the down jacket lining 13 typically sheds down spontaneously, its bottom is actually wider, requiring stronger magnetic force. Therefore, when the flexible magnetic suction part 22 is fully extended upwards, the magnetic attraction strengthens from top to bottom, resulting in a more balanced magnetic force. Furthermore, when the traction rope 27 is pulled upwards, the flexible magnetic suction parts 22 can be extended one by one, thus compressing the thicker area below the lining 13. For the same lining 13, this compression method ensures uniform loft from top to bottom. As more flexible magnetic suction parts 22 are extended, the pressure level on the lining 13 increases progressively, achieving a multi-level adjustment function for loft.

[0027] When it is necessary to reduce the fluffiness, pull the traction rope 27 upward, so that the traction rope 27 pulls the base fabric 21 downward and unfolds it. The flexible magnetic part 22 is attached to the surface of the inner liner 13 and attracts each other with the flexible adsorption layer 25 to press the inner liner 13 to reduce the fluffiness. When the traction rope 27 is pulled up further, more and more of the flexible magnetic part 22 is unfolded, gradually increasing the pressure on the inner liner 13 to achieve the purpose of fluffiness adjustment. After adjustment, the traction rope 27 is fixed by the movable fixing buckle 28. When warmth is needed, the traction rope 27 is released, the base fabric 21 slides down, and is repositioned by the attraction between the flexible magnetic parts 22, and is refolded into the folding cavity 15.

[0028] The embodiments described above are merely examples of several implementations of the present invention, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
