Description

Technical Field

[0001] This utility model relates to an adjustable down jacket with adjustable insulation, belonging to the field of clothing technology. Background Technology

[0002] The primary function of down jackets is to provide excellent warmth in cold environments. The down filling effectively locks in body heat and protects against the low temperatures. Depending on weather changes and individual perception of temperature, different thicknesses of down jackets are needed. For example, in autumn, temperatures are low but not necessarily requiring a heavy down jacket; wearing a heavy down jacket might lead to overheating, while not wearing one might leave one feeling slightly cold. In contrast, in winter, temperatures are extremely low, and ordinary down jackets may not provide sufficient warmth, necessitating a thicker down jacket.

[0003] Traditional down jackets have their insulation layer fixed inside the main body, making it impossible to adjust to changes in external temperature. This forces users to purchase multiple down jackets of different thicknesses for different temperature conditions, increasing costs and inconvenience.

[0004] Furthermore, because the down filling in traditional down jackets is fixed and cannot be removed, it makes cleaning very inconvenient. After washing the entire down jacket, the down tends to clump together, leading to a decrease in its insulation performance.

[0005] Furthermore, since the down filling of traditional down jackets is fixed, if the down in a certain part is damaged or malfunctions, the user cannot replace or repair it separately; the entire garment must be replaced, which increases the cost of use. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a down jacket with adjustable heat insulation effect to solve the problems of the existing technology.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0016] As a further improvement, the front piece, back piece, and inner sleeve layer are all made of mesh, with the opening located above the mesh. An elastic band is provided in the opening area above the mesh to tighten the opening.

[0017] As a further improvement, an extension band is sewn onto the elastic band. One end of the extension band is fitted with a male buckle and the other end with a female buckle. A positioning band is sewn onto the top of the insulation component. The two ends of the positioning band are sewn together to form a positioning hole in the middle. The extension band carrying the male buckle passes through the positioning hole and then wraps back to fasten and fix it to the female buckle.

[0018] As a further improvement, a first connecting component is also provided at the opening. The first connecting component includes a first Velcro sewn to one side of the opening and a second Velcro sewn to the top of the insulation component. The insulation component is inserted into the receiving cavity through the opening, and the top of the insulation component is fixed to the main garment body by the cooperation of the first Velcro and the second Velcro.

[0019] As a further improvement, a third hook and loop fastener is also provided on the other side of the opening, wherein the area above the center line of the first hook and loop fastener is connected to the second hook and loop fastener, and the area below the center line of the first hook and loop fastener is connected to the third hook and loop fastener.

[0020] As a further improvement, the opening is provided on the outer surface above the front piece, the back piece, and the sleeve, and the first insulation piece, the second insulation piece, and the third insulation piece are installed into the corresponding receiving cavity.

[0021] As a further improvement, a second connecting component is also provided in the opening. The second connecting component includes a first zipper tape sewn to one side of the opening, a second zipper tape sewn to the other side of the opening, and a zipper head slidably mounted on the first or second zipper tape.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0039] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] Reference Figure 1-5 As shown, a down jacket with adjustable insulation includes:

[0041] The main garment body 1 includes a set of front pieces 11 and a back piece 12 connecting the two front pieces 11, and a set of sleeves 13 disposed on both sides of the main garment body 1. The upper part of the sleeves 13 is sewn and fixed to the front pieces 11 and the back pieces 12.

[0042] A removable heat-insulating component 14 is installed inside the main garment body 1;

[0043] The front piece 11, the back piece 12, and the sleeve 13 are provided with openings 15 on the inner / outer sides, and the front piece 11, the back piece 12, and the sleeve 13 extend inward from the openings 15 to form a receiving cavity 16.

[0044] The thermal insulation component 14 includes a first thermal insulation sheet 141 that matches the front sheet 11, a second thermal insulation sheet 142 that matches the rear sheet 12, and a third thermal insulation sheet 143 that matches the sleeve 13;

[0045] Through the openings 15 on the front piece 11, the back piece 12, and the sleeve 13, the first heat-insulating sheet 141, the second heat-insulating sheet 142, and the third heat-insulating sheet 143 are installed into the corresponding receiving cavities 16.

[0046] The insulation component 14 can be installed or not depending on changes in the outside temperature. When the weather is cold, the first insulation piece 141 (corresponding to the front piece 11), the second insulation piece 142 (corresponding to the back piece 12), and the third insulation piece 143 (corresponding to the sleeve 13) are installed into the corresponding receiving cavities 16 through the openings 15 on the front piece 11, the back piece 12, and the sleeve 13 to increase the insulation performance of the garment. When the weather warms up, the insulation component 14 can be removed for easy carrying and reinstalled as needed.

[0047] When it is time to wash the garment, the insulation component 14 can be removed first, and only the main garment body 1 can be washed, avoiding the problem of the filling clumping. At the same time, the insulation component 14 itself can also be washed separately to ensure its cleanliness and long-term effectiveness in insulation performance.

[0048] If a problem is found in a certain part of the insulation component 14, such as damage or reduced insulation effect, the insulation sheet of that part can be replaced separately without replacing the entire garment, which greatly reduces costs.

[0049] The above design allows users to freely adjust the thickness of the insulation layer according to their individual needs and weather changes, avoiding the awkward situation of needing multiple down jackets of different thicknesses in different temperature environments. Traditional down jacket insulation layers, once fixed, are difficult to change, potentially resulting in insufficient warmth in winter and excessive stuffiness in spring and summer.

[0050] Furthermore, down jackets are prone to clumping after washing, affecting their loft and warmth. The removable insulation component 14 design allows users to separate the filling from the main body of the garment for individual washing, effectively preventing clumping and ensuring the garment's warmth.

[0051] Because the insulation component 14 can be replaced partially, the need to replace the entire garment due to a problem with a single part is avoided, reducing maintenance and replacement costs. With traditional down jackets, if a part malfunctions, the only option is usually to send the entire garment for repair or replacement, which undoubtedly increases the financial burden on consumers.

[0052] The removable insulation component 14 greatly enhances the flexibility, cleanliness, and economy of clothing, making it easier for users to cope with various wearing and maintenance needs.

[0053] For ease of distinction, the cavity 16 corresponding to the front piece 11 is defined as the first cavity 161, the cavity 16 corresponding to the rear piece 12 is defined as the second cavity 162, and the cavity 16 corresponding to the sleeve is defined as the third cavity 163.

[0054] The front piece 11, the back piece 12, and the sleeve 13 are all provided with double layers, and the accommodating cavity 16 is located in the interlayer.

[0055] The front piece 11, the back piece 12, and the inner layer of the sleeve 13 are all made of mesh 17, and the opening 15 is located above the mesh 17.

[0056] An elastic band 18 is provided in the opening 15 area above the mesh 17, and the opening 15 is tightened by the elastic band 18.

[0057] An extension band 19 is sewn onto the elastic band 18. One end of the extension band 19 is fitted with a male buckle 191, and the other end with a female buckle 20. A positioning band 21 is sewn onto the top of the insulation component 14. The two ends of the positioning band 21 are sewn together to form a positioning hole 22 in the middle. The extension band 19, carrying the male buckle 191, passes through the positioning hole 22 and then wraps back to fasten and secure it to the female buckle 20. Positioning bands 21 are also sewn onto the tops of the first insulation sheet 141, the second insulation sheet 142, and the third insulation sheet 143.

[0058] The opening 15 is located on the inner side above the front piece 11, the back piece 12, and the sleeve 13. The first insulation piece 141, the second insulation piece 142, and the third insulation piece 143 are inserted into the corresponding receiving cavity 16 through the inner opening 15. The amount of down inside the first insulation piece 141, the second insulation piece 142, and the third insulation piece 143 can be adjusted according to the different temperature requirements of spring, autumn, and winter. The first insulation piece 141, the second insulation piece 142, and the third insulation piece 143 are composed of an outer covering layer and an inner down filling, and their shape can be adjusted according to the front piece 11, the back piece 12, and the sleeve 13.

[0059] Depending on the weather conditions, the first insulation sheet 141, the second insulation sheet 142, and the third insulation sheet 143 are inserted into the corresponding receiving cavities 16 through the inner openings 15 of the first cavity 161, the second cavity 162, and the third cavity 163, respectively.

[0060] After inserting the insulation component 14, pass the extension strap 19 with the female buckle 191 through the positioning hole 22 on the insulation component 14, and then wrap it back to fasten it with the female buckle 20. This ensures that the insulation component 14 is securely installed in the receiving cavity 16 and will not slip or fall off during wear.

[0061] When the weather warms up or when cleaning is needed, unfasten the male buckle 191 and female buckle 20 on the extension strap 19, and then remove the insulation component 14 from the corresponding receiving cavity 16 through the opening 15.

[0062] After removing the insulation component 14, the main garment body 1 can be washed separately. Since the inner layer of the main garment body 1 is a mesh 17, it is easier to dry and less prone to damage during washing.

[0063] The insulation component 14 can also be cleaned separately to ensure its cleanliness and insulation performance.

[0064] Users can freely choose whether to install the insulation component 14 according to changes in the outside temperature, so that the down jacket can maintain a suitable warmth in different seasons and environments.

[0065] If a particular area requires more or less insulation, the corresponding insulation sheet can be installed or removed separately to provide a more personalized insulation experience.

[0066] The main garment body 1 and the insulation component 14 can be washed separately, avoiding the problem of down clumping that may occur when washing the entire down jacket, thus extending the service life of the down jacket.

[0067] The inner layer design of mesh 17 makes the main garment body 1 easier to dry after washing, reducing the possibility of mildew and odor.

[0068] If a part of the insulation component 14 is damaged or its performance deteriorates, the insulation sheet in that part can be replaced separately without replacing the entire garment, thus reducing maintenance costs.

[0069] By flexibly replacing and washing down jackets, their lifespan can be significantly extended, reducing the need to frequently buy new clothes.

[0070] The elastic band 18 is designed to secure the insulation component 14 without causing any pressure on the user, thus maintaining wearing comfort.

[0071] The inner layer design of mesh panel 17 increases the breathability of the garment, making it more comfortable for users to wear and reducing sweat buildup and stuffiness.

[0072] With the design of the extension strap 19 and positioning hole 22, the thermal insulation component 14 can be firmly fixed in the receiving cavity 16 and will not fall off even during strenuous exercise or long-term wear.

[0073] Meanwhile, since the insulation component 14 and the main garment body 1 are separate, maintenance and upkeep are more convenient, reducing damage caused by improper maintenance.

[0074] Reference Figure 6 As shown in Figure 8, in order to further enhance the heat preservation and heating effect, it also includes a silicone heating wire 29 sewn inside the heat preservation component 14, a controller 30 connected to the silicone heating wire 29, and an external power supply 31. The external power supply 31 is electrically connected to the controller 30, and the controller 30 controls the silicone heating wire 29 to heat up.

[0075] Connect the external power supply 31 to the controller 30 to ensure that the electrical connection between the controller 30 and the silicone heating wire 29 is normal.

[0076] Adjust the heating level of the silicone heating wire 29 using the controller 30 to select the appropriate insulation temperature for the current environment.

[0077] When it is necessary to turn off the heating function, the heating of the silicone heating wire 29 is stopped by the controller 30.

[0078] Before cleaning, the insulation component 14 needs to be disconnected from the external power supply 31, and the controller 30 part needs to be waterproofed (if necessary, the controller 30 can be removed).

[0079] The silicone heating wire 29 actively heats up, providing a more stable heat retention effect. Users can adjust the heating level as needed to adapt to different temperature environments. The silicone heating wire 29 heats up quickly, raising body temperature in a short time, making it especially practical in cold environments.

[0080] By sewing silicone heating wire 29 inside the insulation component 14 and equipping it with a controller 30 and an external power supply 31, this not only provides active heating, significantly improving the user's warmth experience, but also enhances comfort and ease of operation. Simultaneously, the zipper design provides better sealing and windproof / cold-weather protection, making the overall down jacket more adaptable and perform better in various environments. This design is particularly suitable for users who require high-intensity warmth, such as outdoor sports enthusiasts and residents of cold regions.

[0081] Example 2

[0082] Reference Figure 6 As shown, this embodiment is basically the same as embodiment 1, except that the opening 15 in embodiment 1 is open and is restrained by the elastic band 18, while this embodiment is closed by the cooperation of the Velcro assembly, as detailed below:

[0083] It also includes a first connecting component disposed in the opening 15. The first connecting component includes a first Velcro 23 sewn to one side of the opening 15 and a second Velcro 24 sewn to the top of the insulation component 14. The insulation component 14 is inserted into the receiving cavity 16 from the opening 15. The first Velcro 23 and the second Velcro 24 cooperate to fix the top of the insulation component 14 to the main garment body 1.

[0084] The first insulation sheet 141, the second insulation sheet 142, and the third insulation sheet 143 are all sewn with second Velcro 24.

[0085] It also includes a third hook and loop fastener 25 disposed on the other side of the opening 15, wherein the area above the center line of the first hook and loop fastener 23 is connected to the second hook and loop fastener 24, and the area below the center line of the first hook and loop fastener 23 is connected to the third hook and loop fastener 25.

[0086] Among them, the second hook and loop fastener 24 and the third hook and loop fastener 25 are velvet-faced, and the first hook and loop fastener 23 is a barbed-faced.

[0087] Install the thermal insulation component 14, and insert the first thermal insulation sheet 141, the second thermal insulation sheet 142, and the third thermal insulation sheet 143 into the receiving cavity 16 from the openings 15 of the corresponding front piece 11, back piece 12, and sleeve 13, respectively.

[0088] Align and attach the second Velcro 24 above the insulation component 14 with the first Velcro 23 (stab-face patch) on one side of the opening 15 of the main garment body 1.

[0089] Align and adhere the hook and loop fastener below the center line of the first hook and loop fastener 23 with the third hook and loop fastener 25 (velvet fastener) on the other side of the opening 15 to ensure that the opening 15 is completely closed.

[0090] Remove the insulation component 14 and unfasten the first hook and loop fastener 23 and the second hook and loop fastener 24. Unfasten the first hook and loop fastener 23 and the third hook and loop fastener 25. Remove the insulation component 14 from the corresponding receiving cavity 16 through the opening 15.

[0091] After removing the insulation component 14, the main garment body 1 can be washed separately. The inner layer design of the mesh 17 makes washing easier and drying faster. The insulation component 14 can also be washed separately to ensure its cleanliness and insulation performance.

[0092] Compared to elastic band 18, Velcro has better sealing properties, ensuring that opening 15 is completely sealed, preventing cold air or moisture from entering the cavity 16, and improving insulation and waterproof performance.

[0093] The area above the center line of the first hook and loop fastener 23 is bonded to the second hook and loop fastener 24, and the area below the center line is bonded to the third hook and loop fastener 25. This design provides double fixation, ensuring that the insulation component 14 is more secure during wear. It can both position and fix the upper part of the insulation component 14 and close the opening 15.

[0094] Unlike elastic bands, Velcro fastens don't create pressure on the skin, making them more comfortable to wear. The Velcro design also ensures a smoother fit, preventing bulges inside clothing that could negatively impact the wearing experience.

[0095] By using Velcro closures to seal the opening 15 and secure the insulation component 14, this design not only improves the down jacket's adaptability and warmth in different environments but also enhances the user experience and the garment's durability. Users can more easily adjust and wash the down jacket, ensuring it maintains good performance and appearance over extended use. This design offers significant advantages in terms of practicality, comfort, and economy.

[0096] Example 3

[0097] Reference Figure 7 As shown, this embodiment is basically the same as embodiment 1 / 2, except that the opening 15 is set on the outer side, and the zipper assembly is used instead of the Velcro assembly, as detailed below:

[0098] The opening 15 is provided on the outer side above the front piece 11, the back piece 12 and the sleeve 13, and the first heat insulation piece 141, the second heat insulation piece 142 and the third heat insulation piece 143 are installed into the corresponding receiving cavity 16.

[0099] It also includes a second connecting component 32 disposed in the opening 15. The second connecting component 32 includes a first zipper tape 26 sewn to one side of the opening 15, a second zipper tape 27 sewn to the other side of the opening 15, and a zipper head 28 slidably mounted on the first zipper tape 26 or the second zipper tape 27. The receiving cavity 16 is opened / closed by sliding the zipper head 28 to cooperate with the first zipper tape 26 or the second zipper tape 27.

[0100] Install the thermal insulation component 14, and insert the first thermal insulation sheet 141, the second thermal insulation sheet 142, and the third thermal insulation sheet 143 into the receiving cavity 16 from the outer opening 15 of the corresponding front piece 11, back piece 12, and sleeve 13, respectively.

[0101] By sliding the zipper head 28, the first zipper tape 26 and the second zipper tape 27 are completely closed, ensuring that the heat preservation component 14 is firmly fixed in the accommodating cavity 16 and the opening 15 is completely closed.

[0102] Remove the insulation component 14, pull open the zipper head 28, and fully open the first zipper strap 26 and the second zipper strap 27.

[0103] The insulation component 14 is removed from the corresponding receiving cavity 16 through the outer opening 15.

[0104] After removing the insulation component 14, the main garment body 1 can be washed separately. The insulation component 14 can also be washed separately to ensure its cleanliness and insulation performance.

[0105] Because zippers provide a better seal than Velcro and elastic bands 18, they ensure that the opening 15 is completely sealed, preventing cold air or moisture from entering the cavity 16 and improving insulation and waterproofing.

[0106] The opening 15 on the outside allows for simple and quick opening and closing of the zipper, and users can easily adjust the thickness of the insulation layer in different temperature environments without complicated bonding steps.

[0107] The zipper design allows users to clearly see and operate the opening 15, reducing uncertainty during operation.

[0108] The zipper provides better closure than Velcro, preventing accidental opening during strenuous exercise or external friction, and ensuring that the insulation component 14 remains securely within the receiving cavity 16 during wear.

[0109] The zipper is more securely fastened, reducing the risk of it coming undone due to external factors.

[0110] By placing the opening 15 on the outer side and replacing the Velcro assembly with a zipper assembly, the design not only provides better sealing and durability but also enhances the user experience and the garment's aesthetics. Users can more easily adjust and wash the down jacket, ensuring it maintains good performance and appearance over extended use. This design offers significant advantages in practicality, comfort, and economy, making it ideal for down jacket users who require frequent adjustment and washing.

[0111] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
