Abstract
Description
Technical Field
[0001] This utility model relates to the field of stealth technology, and in particular to an invisibility cloak. Background Technology
[0002] With the continuous development of technology, infrared target detection methods have emerged, and in order to avoid being detected, stealth technology has been developed. Especially during outdoor missions, invisibility cloaks are often needed to achieve concealment.
[0003] Current invisibility cloaks are made of four or more layers of fabric. While they have the advantage of covering multiple wavelengths, they lack breathability, resulting in stuffiness and making them unsuitable for prolonged wear. Utility Model Content
[0004] The main purpose of this invention is to propose an invisibility cloak that aims to solve the problem of insufficient breathability in existing invisibility cloaks.
[0005] To achieve the above objectives, the invisibility cloak proposed in this utility model includes a hood, a top, and pants. The hood, top, and pants all include a three-layer fabric structure, which includes a heat-insulating inner layer, a middle strip of fabric, and a breathable outer layer.
[0006] The middle layer fabric strip is sewn to the inner heat-insulating layer. The breathable outer layer has multiple staggered arc-shaped slits. The middle layer fabric strip is staggered with the adjacent arc-shaped slits, and the middle layer fabric strip passes through the arc-shaped slits and extends out of the breathable outer layer, hanging down outside a portion of the arc-shaped slits.
[0007] In some embodiments, a heat dissipation channel is provided between the heat-insulating inner layer and the breathable outer layer, and the heat dissipation channel is connected to the arc-shaped cut.
[0008] In some embodiments, the breathable outer layer and the middle layer strip are coated with a flame-retardant coating.
[0009] In some embodiments, the hood includes a head cover and a heat shield connected to the head cover and extending to the garment to overlap with it.
[0010] In some embodiments, the heat shield is triangular in shape, with its width covering the shoulder and its length extending to below the level of the armpit.
[0011] In some embodiments, the trousers are overalls with crisscrossing straps and buckles.
[0012] In some implementations, the cuffs of the jacket and the hems of the trousers are provided with elasticated cuffs.
[0013] In some embodiments, the middle layer strip is elongated and the width of the middle layer strip ranges from 8 mm to 12 mm.
[0014] In some embodiments, the straight-line distance of the arc-shaped cut is 40mm to 50mm.
[0015] The technical solution of this utility model employs a three-layer fabric structure for the headgear, top, and trousers. This three-layer structure includes a heat-insulating inner layer, a middle fabric strip, and a breathable outer layer. The middle fabric strip is sewn to the heat-insulating inner layer. The breathable outer layer has multiple staggered arc-shaped slits. The middle fabric strip is staggered with adjacent arc-shaped slits and extends through them, hanging over part of the arc-shaped slits. This creates a labyrinthine, irregular airflow channel that slows heat dissipation, while the hanging portion again covers part of the arc-shaped slits, facilitating heat dissipation and breathability while layering and reducing infrared radiation. This utility model, made with a three-layer fabric structure, reduces heat conduction while maintaining breathability. Attached Figure Description

[0027] Current invisibility cloaks are made of four or more layers of fabric. While they have the advantage of covering multiple wavelengths, they lack breathability, resulting in stuffiness and making them unsuitable for prolonged wear.
[0028] This invention proposes an invisibility cloak. Please refer to [link / reference]. Figure 1 In one embodiment of the present invention, the invisibility cloak proposed by the present invention includes a headgear 10, a top 20 and pants 30. The headgear 10, the top 20 and the pants 30 all include a three-layer fabric structure 40, which includes a heat-insulating inner layer 41, a middle layer of fabric strips 42 and a breathable outer layer 43.
[0029] The middle layer fabric strip 42 is sewn to the heat insulation inner layer 41. The breathable outer layer 43 has multiple staggered arc-shaped cuts 431. The middle layer fabric strip 42 is staggered with the adjacent arc-shaped cuts 431, and the middle layer fabric strip 42 passes through the arc-shaped cuts 431 and hangs down outside part of the arc-shaped cuts 431.
[0030] The technical solution of this utility model adopts a three-layer fabric structure 40, which includes a headgear 10, a top 20, and pants 30. The three-layer fabric structure 40 includes a heat-insulating inner layer 41, a middle layer strip 42, and a breathable outer layer 43. The middle layer strip 42 is sewn to the heat-insulating inner layer 41. The breathable outer layer 43 has staggered arc-shaped cuts 431. The middle layer strip 42 is staggered with the adjacent arc-shaped cuts 431, and the middle layer strip 42 passes through the arc-shaped cuts 431 and hangs down outside part of the arc-shaped cuts 431. This forms a labyrinthine irregular airflow channel to slow down heat dissipation, while the hanging part covers part of the arc-shaped cuts 431 again, forming a heat dissipation and breathability effect. This utility model is made of the three-layer fabric structure 40, which can reduce heat conduction and maintain breathability.
[0031] In one embodiment, the multiple arc-shaped cuts 431 of the breathable outer layer 43 are staggered with the middle layer strips 42 to form a labyrinthine irregular airflow channel that slows down heat dissipation. Heat is dissipated from the arc-shaped cuts 431, improving heat dissipation efficiency by 40% compared to the prior art invisibility cloaks made of four layers of fabric. The invisibility cloak of this invention is made of three layers of fabric to effectively reduce the direct effect of infrared radiation emitted by the human body, while also facilitating heat dissipation and breathability.
[0032] Specifically, the breathable outer layer 43 has multiple arc-shaped cuts 431, and the middle layer fabric strip 42 is exposed and hangs down through one or more of the arc-shaped cuts 431. To ensure that heat can be dissipated from the breathable outer layer 43, the multiple arc-shaped cuts 431 are staggered, with some arc-shaped cuts 431 exposing the middle layer fabric strip 42 and others not exposing the middle layer fabric strip 42, thereby facilitating the dissipation of heat from the multiple arc-shaped cuts 431.
[0033] Both the middle layer fabric strip 42 and the breathable outer layer 43 are made of low-emissivity fabric. The breathable outer layer 43 is made of nylon fabric; the middle layer fabric strip 42 is a long strip of nylon fabric. One end of the middle layer fabric strip 42 is sewn to the heat-insulating inner layer 41, and the other end of the middle layer fabric strip 42 extends out of the arc-shaped cutout 431 of the breathable outer layer 43.
[0034] In one embodiment, the heat-insulating inner layer 41 is provided with a fine mesh structure. Heat from the human body is dissipated through the mesh of the heat-insulating inner layer 41.
[0035] For further details, please refer to Figure 1 The heat-insulating inner layer 41 and the breathable outer layer 43 have a heat dissipation channel 44, which communicates with the arc-shaped cutout 431. Heat from the human body is dissipated through the mesh of the heat-insulating inner layer 41 to the heat dissipation channel 44, and then from the heat dissipation channel 44 through the arc-shaped cutout 431 to the external environment. Therefore, the invisibility cloak has good breathability.
[0036] In some embodiments, the breathable outer layer 43 and the middle fabric strip 42 are coated with a flame-retardant coating. The flame-retardant coating employs a combination of bromine / antimony-based flame retardancy and durable flame retardancy.
[0037] Furthermore, a flame-retardant coating is applied to the breathable outer layer 43 to form a camouflage pattern. The camouflage pattern uses three-color paint superimposed to achieve the fusion of the target and background in the infrared and visible light regions by utilizing the combination of light and dark in the coating and holes.
[0038] Please see Figure 2 The headgear 10 includes a head protection 11 and a heat shield 12, the heat shield 12 being connected to the head protection 11 and extending to the top 20 to overlap with the top 20.
[0039] The headgear 10 includes a front section and a middle section. The front section is made of high-strength polyester fabric with good drape, coated with polyurethane and flame-retardant heat-insulating materials. The front section has an arc-shaped cutout 431 with a diameter of 3.5mm × 3.5mm to provide both visible light camouflage and breathability. The camouflage pattern on the front section can be adapted to desert or jungle environments. The camouflage pattern is based on a basic pattern with overlapping colors. The width of the overlapping colors ranges from 50mm × 50mm to 150mm × 150mm.
[0040] The camouflage pattern in the middle can be generated using a fractal algorithm. The camouflage pattern has multiple basic color blocks, each 100mm x 100mm in size, and the edges of the color blocks are provided with a wide transition band of 0.5mm to 1mm to eliminate the hard edge effect in the visible light band.
[0041] The heat-masking portion 12 of the headgear 10 extends to the upper garment 20. The heat-masking portion 12 overlaps with the upper garment 20 to cover the high heat dissipation area of the human body above the neck and back.
[0042] The headgear 10 is made using the three-layer fabric structure 40, which can reduce heat conduction and maintain breathability.
[0043] The garment 20 includes a torso area and is made of the three-layer fabric structure 40 to maintain breathability while reducing heat conduction. The cuffs 21 of the garment 20 are designed with an elasticated cuff structure. Specifically, the cuffs 21 of the garment 20 may be sewn with elastic bands or drawstrings to allow the cuffs 21 of the garment 20 to be narrowed and gathered.
[0044] This invention adds a heat shielding part 12 to the headgear 10 to overlap and cover the high heat dissipation area of the neck and back, thereby reducing infrared signature.
[0045] In one embodiment, the heat shield 12 is triangular in shape, with its width covering the shoulder and its length extending to below the level of the armpit.
[0046] Please see Figure 3 The trousers 30 are overalls, with suspenders 32 arranged in a crisscross pattern and equipped with buckles 33. The suspender design prevents the trousers 30 from slipping off during rapid movement or vigorous activity. The suspenders 32 are made of nylon. The main body of the trousers 30 is made of the three-layer fabric structure 40 to reduce heat conduction while maintaining breathability.
[0047] In one embodiment, please refer to Figure 2 and Figure 3 The cuffs 21 and the trouser legs 31 of the pants 30 are provided with elastic cuffs for easy putting on and taking off. Specifically, the trouser legs 31 can be sewn with elastic bands or drawstrings so that the trouser legs 31 can be narrowed and gathered by the drawstrings.
[0048] Optionally, the middle layer fabric strip 42 is long and narrow, with a width ranging from 8mm to 12mm, so as to conceal and blend into the environment while reducing the amount of the middle layer fabric strip 42 obscuring the arc-shaped cut 431.
[0049] In one embodiment, the width of the middle layer strip 42 is 8mm to 12mm, and the length of the middle layer strip 42 can be 50mm.
[0050] In one embodiment, the straight-line distance of the arc-shaped cuts 431 is 40mm to 50mm. Heat from the human body can dissipate through the gaps between the multiple middle-layer fabric strips 42 in the arc-shaped cuts 431.
[0051] In one embodiment, the arc-shaped cut 431 may also be a semi-circular arc-shaped cut to allow the middle layer fabric strip 42 to be pulled out from the heat-insulating inner layer 41.
[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
