Description

A self-windproof thin-layer warm and breathable clothing structure and down jacket Technical Field

[0001] The present invention relates to the field of clothing, in particular to an autonomous windproof, thin-layer, warm-keeping and breathable clothing structure and a down jacket. Background Art

[0002] Referring to the applicant's prior patent application with publication number CN116919030A, entitled "A Thin-Layer Thermal Insulation Down Jacket," the core of this prior patent is to provide a number of inclined connecting belts between the outer fabric and lining of the down jacket, and to provide heat-reflective materials on the connecting belts, thereby utilizing the inclined connecting belts to reflect infrared radiation emitted by the body. At the same time, the gaps between adjacent connecting belts can also serve as ventilation channels.

[0003] This solution can achieve excellent results in thin-layer thermal insulation while maintaining excellent air permeability and improving the durability of heat-reflective materials. However, there are the following problems:

[0004] The solution of the prior patent has excellent breathability, but in this solution, the breathability may be bidirectional, that is, it can ventilate from the inside of the body to the outside to expel moisture, and this breathability process is desirable. There is also an undesirable "breathability", and when it is windy outdoors, cold air will also flow into the down jacket through the breathable channel. This is essentially a heat convection heat exchange method. Although the prior patent can effectively block heat radiation (relying on the reflection of infrared radiation by the connecting belt) and heat conduction (relying on the low thermal conductivity of down and air), it is obvious that in order to maintain breathability, the solution of the prior patent cannot block the backflow of cold air. This will seriously affect the thermal insulation effect of the down jacket of the prior patent when worn in windy scenes. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the background technology, the present invention:

[0006] The first purpose is to request protection for a thin layer of warm and breathable clothing structure that is self-windproof;

[0007] The second purpose is to request protection for down jackets that use the above-mentioned self-windproof thin-layer warm and breathable clothing structure, which can maintain good breathability in a windless or breezy environment, and independently embody the windproof function in a windy environment.

[0008] Technical solution: The self-windproof, thin-layer, warm and breathable clothing structure disclosed in the present invention comprises a main body comprising a fabric, a lining and a connecting belt obliquely arranged between the fabric and the lining. Two adjacent connecting belts and the fabric and the lining form a filling cavity, which is filled with a warming material.

[0009] A ventilation partition layer is provided in the filling cavity, and both sides of the partition layer are connected to adjacent connecting strips respectively, dividing the filling cavity into an inner filling cavity and an outer filling cavity;

[0010] The partition layer is located on one side of the outer filling cavity and is provided with a number of louver-shaped windproof curtains. The first edge of the windproof curtain is connected to the partition layer, and the second edge opposite to it is free. Supported by the thermal insulation material, the windproof curtain is in an open state; after the windproof curtain closes around the first edge under the action of wind, its second edge covers the first edge of another windproof curtain adjacent to it, thereby shielding the partition layer.

[0011] Furthermore, the thermal insulation material is down, chemical fiber or cotton.

[0012] Furthermore, the partition layer and the connecting belt are connected by sewing, gluing or hot pressing.

[0013] Furthermore, the partition layer is provided on a side close to the fabric.

[0014] Furthermore, the partition layer is arranged parallel to the outer fabric and the lining.

[0015] Furthermore, the windproof curtain is made of windproof densely woven fabric, or a windproof coating is provided on the fabric.

[0016] Furthermore, the windproof curtains extend transversely on the partition layer and are arranged at intervals longitudinally, and the first edge is the upper edge of the windproof curtains.

[0017] Furthermore, the width of the windproof curtain is less than or equal to 4 cm.

[0018] Furthermore, the windproof curtain is a heat-reflecting curtain.

[0019] A self-windproof, thin-layer, warm-keeping, and breathable down jacket is based on the above-mentioned self-windproof, thin-layer, warm-keeping, and breathable clothing structure, wherein the warm-keeping material is down.

[0020] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0021] This solution overcomes the industry's prejudice that breathability and windproofness are incompatible. It can automatically switch between breathable and windproof modes according to the actual scenario. It can maintain good breathability in windless or light breeze environments, and automatically provide windproof function in windy environments.

[0022] The adjustment process does not require manual or electric adjustment, nor does it require additional drive or transmission components, making it simple and effective.

[0023] At the same time, the thin layer insulation effect in the prior patent is maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] The self-windproof, thin-layer, warm and breathable clothing structure of the present invention is improved based on the prior patent application CN116919030A.

[0030] As shown in Figures 1 and 2, the main body includes a fabric 1, a lining 2, and a connecting strip 3 arranged obliquely between the fabric 1 and the lining 2. The connecting strip 3 is made of a heat-reflective material or provided with a heat-reflective material by coating or adhering. Two adjacent connecting strips 3, the fabric 1, and the lining 2 form a filling cavity, which is filled with a thermal insulation material 4. For other parts, refer to the description of the prior patent.

[0031] A breathable barrier layer 5 is provided on the side of the filling cavity close to the fabric 1 and is parallel to the fabric 1 and spaced a certain distance apart. Both sides of the barrier layer 5 are connected to adjacent connecting strips 3, dividing the filling cavity into an inner filling cavity 6 and an outer filling cavity 7. Since the barrier layer 5 is a breathable structure, direct air permeability is achieved between the inner filling cavity 6 and the outer filling cavity 7, and the thermal insulation materials between the two cavities are ensured to not interfere with each other.

[0032] The isolation layer 5 and the connecting belt 3 are connected by known means such as sewing, gluing or hot pressing.

[0033] As shown in Figures 3 and 4, the partition layer 5 is located on one side of the outer filling cavity 7 and is provided with a number of louver-shaped windproof curtains 8. The first edge 9 of the windproof curtain 8 is connected to the partition layer 5, and the second edge 10 opposite to it is free. Under the support of the thermal insulation material 4, the windproof curtain 8 is in an open state; after the windproof curtain 8 is closed around the first edge 9 under the action of the wind, its second edge 10 covers the first edge of another windproof curtain adjacent to it, thereby shielding the partition layer 5.

[0034] The windproof curtain 8 can be made of windproof densely woven fabric, or can be achieved by providing a windproof coating on ordinary fabric. Windproofing of fabric is a well-known method.

[0035] In a windless state, the thermal insulation material 4 filled in the inner filling cavity 6 and the outer filling cavity 7 is in a fluffy state, which can support the windproof curtain 8 and make it open, so that the gap between adjacent windproof curtains 8 provides a ventilation channel connected to the filling cavity; in a windy outdoor scene, the fabric 1 is affected by the wind and forms an extrusion force in the direction of the body. The extrusion force acts on the windproof curtain 8, causing it to overcome the supporting effect of the thermal insulation material and close, thereby blocking the ventilation channel.

[0036] The windproof curtain 8 extends horizontally on the partition layer 5 and is arranged at intervals longitudinally. The first edge 9 is the upper edge of the windproof curtain 8. The width of the windproof curtain 8 (referring to the distance from the first edge to the second edge) is less than or equal to 4 cm. Excessive width will cause the weight of a single windproof curtain 8 to be too large, and it will not be able to be supported by the fluffiness of the thermal insulation material, which will cause the windproof curtain 8 to be in a normally closed state.

[0037] In conventional Venetian blinds, the inside of the blinds is a completely continuous channel. However, this structure is undesirable in this solution. The barrier layer 5 in this solution should separate the two filling cavities and restrict the free migration of filling material within the two filling cavities. Otherwise, the filling material in the outer filling cavity 7 may be insufficient, and the windproof curtain 8 may not be able to provide sufficient support.

[0038] The windproof curtain 8 can also have the same heat-reflecting function as the connecting belt 3 (for example, by applying a heat-reflecting coating to the windproof curtain 8). This can further enhance the heat-reflecting and heat-insulating effect compared to the prior patent. This is because the ventilation channel in the prior patent does not have a heat-reflecting function along its central axis. Down jackets inevitably wrinkle or shake when worn, so some infrared radiation along the central axis of the ventilation channel cannot be effectively reflected, resulting in heat loss. However, the present solution also provides the windproof curtain 8 with a heat-reflecting function, effectively preventing the loss of infrared radiation along the central axis of the ventilation channel.

[0039] In this structure, the thermal insulation material 4 is down, chemical fiber or cotton, preferably down, forming a thin-layer thermal insulation down jacket that can maintain good air permeability in a windless or breezy environment and independently embody the windproof function in a windy environment.
