Description

Technical Field

[0001] The invention belongs to the technical field of jackets, in particular to a composite waterproof and breathable jacket. Background Art

[0002] Jacket, which is translated as "jacket", is one of the essential equipment for outdoor sports. The reason why the jacket has become the first choice of all outdoor enthusiasts is due to its all-weather function. Jacket is not mysterious, it is just a jacket, but when this functional clothing was introduced to China from abroad, in order to distinguish it from ordinary clothes, the Chinese people started with its "literal translation" and called it "jacket".

[0003] The windbreaker was first used for the final charge to the summit of a high-altitude snow-capped mountain, 2-3 hours away. At this time, the down jacket would be taken off, the large backpack would be removed, and only a lighter piece of clothing would be worn to move forward lightly. This is the origin of the Chinese name "windbreaker".

[0004] During outdoor sports, the wearer often experiences various harsh outdoor environments with the jacket, such as various cold environments. In this process, in order to reduce heat loss and improve thermal insulation performance, the wearer often tightens the collar of the jacket to reduce the air flow inside and outside the jacket, thereby reducing heat loss.

[0005] The most common way to tighten the collar of a jacket is to use a drawstring adjustment method. A drawstring is set at the collar and the collar can be contracted by pulling the drawstring, thereby achieving the effect of tightening the collar. However, in this method, during the tightening process, the fabrics at the collar position are folded together to shrink the collar. After tightening, a small gap exists between the folded position and the skin, and the heat of the human body is easily dissipated from the gap, affecting the overall thermal insulation performance of the jacket.

[0014] Preferably, the tensioning rope comprises a supporting section and an expansion section, the supporting section and the expansion section are staggered and distributed with each other, and the hardness of the material of the expansion section is smaller than the hardness of the material of the supporting section.

[0015] Preferably, a filling section is arranged outside the expansion section, and the filling section is an airbag-like structure and wraps the outer surface of the expansion section to present an annular structure.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] A composite waterproof and breathable jacket, comprising a body 1, the body 1 having a collar 2 and sleeves 3; the body 1 is made of a three-layer composite structure, including a thermal insulation layer 11, a breathable layer 12 and a protective layer 13 from inside to outside, the thermal insulation layer 11 is made of graphene fabric, the breathable layer 12 is made of PU microporous high-transmittance white film material, and the protective layer 13 is made of high-density checkered woven fabric;

[0038] A cloth tube 4 is fixed on the inner surface of the collar 2. The cloth tube 4 is in an arc shape, and a tensioning rope 5 is slidably inserted in the cloth tube 4. The ends of the tensioning rope 5 extend from the corresponding openings on both sides of the cloth tube 4, and extend to the outside through the tensioning holes 21 arranged on the collar 2 near the openings; a positioning component 6 is fixed on the body 1, and the positioning component 6 is used to squeeze and position the two ends of the tensioning rope 5; the tensioning rope 5 is a tubular structure made of elastic material, and interfaces are arranged on the ends of both sides of the tensioning rope 5, and a control valve is arranged in the interface. The control valve uses an existing tire inflation port valve to keep the interface closed normally to control the air pressure in the internal area of ​​the tensioning rope 5, and can also inflate the tensioning rope 5 through the interface to increase the internal air pressure of the tensioning rope 5.

[0039] Specific work flow: This application sets the fabric of the body 1 as a three-layer composite structure, in which the innermost insulation layer 11 close to the human body adopts graphene fabric to utilize the characteristics of graphene to achieve functions such as conductivity and self-heating, thereby achieving better insulation effect; the middle breathable layer 12 adopts PU microporous high-transmittance white film material to achieve maximum color isolation, and has high waterproof and high moisture permeability functions. It can withstand the test of any harsh environment, and has the functions of breathability and moisture permeability while being windproof and waterproof, so that the upper body of the garment will not be suffocated or sweaty when wearing it; the outermost protective layer 13 is made of high-density checkered woven fabric material, which has been treated with three protections to ensure that the surface can withstand the harsh outdoor environment to the maximum extent, is wear-resistant, and difficult to damage, so that the wearer is also well protected in harsh and complex environments, ensuring the safety of the wearer;

[0040] Furthermore, the fabric tube 4 between the collar 2 and the wearer's skin surface is made of a loose porous material with good air permeability, such as porous polyester yarn; in this way, when the external environment is hot, the tension rope 5 is tightened and kept in a relaxed state, and the tension rope 5 inside the fabric tube 4 has not expanded yet, so the gap between the tension rope 5 and the inner wall of the fabric tube 4 is large, and the external air flow can smoothly pass through the fabric tube 4 and pass through the gap between the tension rope 5 and the inner wall of the fabric tube 4, so as to realize the air flow exchange between the inside and outside of the jacket, and the excellent air permeability can improve the comfort of the wearer, so that the wearer can exercise in a better state;

[0041] When the external environment is cold, the tension rope 5 of the tubular structure and the fabric tube 4 on the inner surface of the collar 2 can cooperate with each other. When the collar needs to be close to the skin, the operator needs to pull the two ends of the tension rope 5 downward to tighten the tension rope 5 and close to the skin, and fix the pulled tension rope 5 by the positioning component 6; then, the tension rope 5 part outside the fabric tube 4 can be squeezed to make the stretched tension rope 5 pressurized and cause the internal airflow to flow to the tension rope 5 part located in the collar 2, so that the tension rope 5 located in the fabric tube 4 inside the collar 2 expands and squeezes the wrinkled part between the fabric tube 4 of the collar 2 and the skin, so that the wrinkled part is flattened, thereby reducing the size of the gap between the collar 2 and the skin, preventing the exchange of airflow between the inside and outside environment of the jacket, and better preventing the loss of human body heat, better keeping the human body warm, and ensuring the safety of the wearer of the jacket in cold environments;

[0042] Furthermore, in addition to the collar 2 of the jacket, the tightening and fitting technology of the tensioning rope 5, the fabric tube 4 and the positioning assembly 6 in the present application can also be applied to the cuffs and the lower waist opening of the jacket, thereby fully reducing heat loss and improving thermal insulation performance.

[0043] Embodiment 2:

[0044] On the basis of the first embodiment, the positioning assembly 6 comprises a mounting box 61, the mounting box 61 is fixed on the garment body 1, both ends of the mounting box 61 are provided with through holes 62, and the ends of the tension rope 5 pass through the two through holes 62 of the mounting box 61 in sequence; two clamping seats 63 are symmetrically slidably connected on both sides of the tension rope 5 in the mounting box 61, and the opposite sides of the two clamping seats 63 are respectively connected to the inner wall of the mounting box 61 through elastic members, and the elastic members here can be springs;

[0045] Push rods 631 are fixed on the opposite surfaces of the two clamping seats 63. The push rod 631 on one side of the clamping seat 63 slides horizontally through the clamping seat 63 on the other side and passes through the side wall of the installation box 61 to connect with the external pressure plate 632; Figure 8 As shown, the pressing plate 632 on the left side of the tensioning rope 5 is fixedly connected to the clamping seat 63 on the right side, and the pressing plate 632 on the right side of the tensioning rope 5 is fixedly connected to the clamping seat 63 on the left side; under normal conditions, the clamping seats 63 on both sides of the tensioning rope 5 squeeze the tensioning rope 5 in the middle under the action of the elastic member, so that it is clamped and limited; when the wearer presses the pressing plates 632 on both sides, the clamping seats 63 on both sides of the tensioning rope 5 can be pushed away from each other, the clamping fixation of the tensioning rope 5 is released, and the length of the tensioning rope 5 inside the cloth tube 4 is controlled, thereby adjusting the tightness of the collar 2;

[0046] A clamping roller 633 is provided on the clamping seat 63 near the tensioning rope 5 , and the clamping roller 633 is rotatably connected to the clamping seat 63 , and the clamping rollers 633 located on both sides of the tensioning rope 5 inside the installation box 61 are in close contact with the surface of the tensioning rope 5 .

[0047] Specific working process: Based on the specific working process in the first embodiment, when the collar 2 opening needs to be tightened under cold conditions, the wearer pulls the end of the tensioning rope 5 through the bottom opening 62 of the installation box 61 without pressing the pressure plates 632 on both sides, and then continues to pull it down; the tensioning rope 5 will pass between the clamping seats 63 on both sides during the movement, and the two clamping seats 63 have a tendency to approach each other under the elastic force of the elastic member, so that the passing tensioning rope 5 can be squeezed;

[0048] During the squeezing process, the inner walls of the tension rope 5 are squeezed to contact and seal each other, and the space above and below the tension rope 5 at the clamping seat 63 are separated. As the tension rope 5 is pulled, the length of the tension rope 5 above the clamping seat 63 gradually decreases, that is, the air storage space of the tension rope 5 above the clamping seat 63 gradually decreases, and the air pressure increases, so that the tension rope 5 above the clamping seat 63 will expand; during the expansion process, the tension rope 5 will further squeeze and expand the fabric tube 44 from the inside to be closer to the skin, thereby ensuring the sealing of the neck of the jacket and the overall thermal insulation performance of the jacket;

[0049] After the fabric tube 44 expands, it will flatten the wrinkles on the inner wall of the collar 2 generated during the tightening process, making its surface smoother, thereby improving the comfort of the wearer after contacting the human skin, and also reducing the size of the gap between the wrinkles, thereby reducing heat dispersion, which is beneficial to improving the sealing of the neck of the jacket;

[0050] On the other hand, in the process of pulling the tensioning rope 5 downward to move, the clamping roller 633 can rotate driven by the friction force, which is beneficial to reducing the friction and wear between the tensioning rope 5 and the clamping roller 633 during the movement; after the tensioning ropes 5 on both sides are fully pulled out and the internal air is concentrated in the position where the tensioning ropes 5 are located inside the cloth tube 4, the tensioning ropes 5 on both sides are pulled together and knotted, and the knotting position is close to the installation box 61, so that the opening of the collar 2 is fully tightened, and at the same time, it can also prevent the air in the position of the tensioning rope 5 inside the cloth tube 4 from penetrating downward.

[0051] Embodiment three:

[0052] On the basis of the second embodiment, the tensioning rope 5 includes a supporting section 51 and an expansion section 52, the supporting section 51 and the expansion section 52 are staggered with each other, and the hardness of the material of the expansion section 52 is less than the hardness of the material of the supporting section 51; a filling section 53 is arranged on the outside of the expansion section 52, the filling section 53 is an airbag-like structure, and wraps the outer surface of the expansion section 52 to present an annular structure.

[0053] Specific working process: On the basis of the specific working process in the second embodiment, when the collar 2 opening of the jacket needs to be tightened, the tension ropes 5 on both sides are pulled to reduce the tension rope 5 portion inside the fabric tube 4 in the neckline, and the installation box 61 is cooperated to make the air inside the tension rope 5 located outside the fabric tube 4 be compressed and concentrated toward the tension rope 5 portion located inside the fabric tube 4, so that the tension rope 5 expands and fills the inside of the fabric tube 4, and then the fabric tube 4 expands and fills the gap area between the wearer's neck surface and the fabric tube 4;

[0054] During this process, because the cloth tube 4 is tightened, a large number of wrinkles will appear on the surface of the cloth tube 4, and the expansion section 52 on the tension rope 5 is made of a soft material, so the expansion degree after inflation is greater than that of the support section 51, so evenly distributed annular protrusions will be formed on the surface of the tension rope 5;

[0055] As the tensioning rope 5 expands and fits tightly against the inner wall of the fabric tube 4, the annularly raised expansion section 52 can be embedded in the wrinkle gap formed by the fabric tube 4, so that the wrinkles are squeezed and filled from the inside of the fabric tube 4, causing the outer surface of the fabric tube 4 to tend to be smooth and flat, and to fit more closely against the wearer's skin surface; and compared with the expansion section 52 whose surface strength increases after expansion, the filling section 53 located on the outside of the expansion section 52 is not connected to the expansion section 52 inside, so that it can be smoothly deformed during the contact with the wrinkles of the fabric tube 4, so that at the position of the annular raised surface formed by the expansion section 52, the surface of the filling section 53 is compressed and fits with the wrinkled part of the fabric tube 4, thereby reducing the size of the gap between the surface of the expansion section 52 and the wrinkled part of the fabric tube 4, further promoting the fabric tube 4 to fully fit against the skin surface, and effectively preventing the airflow inside and outside the jacket from exchanging through the gap between the wrinkled part of the surface of the fabric tube 4 and the skin, thereby reducing the heat loss of the wearer.

[0056] Embodiment 4:

[0057] On the basis of the third embodiment, a ring-shaped heat-insulating sheet 531 is provided on the outer surface of the filling section 53 near the supporting section 51, and the heat-insulating sheet 531 is made of wool;

[0058] Specific working process: Based on the specific working process in the third embodiment, during the inflation process of the tension rope 5 inside the cloth barrel 4, the expansion section 52 thereof is pressed and bulged, driving the corresponding part of the cloth barrel 4 to be lifted and straightened, so that the cloth barrel 4 at the corresponding part of the expansion section 52 is flatter, and the wrinkles formed on the surface of the cloth barrel 4 are concentrated in the concave gap formed between adjacent expansion sections 52, and are squeezed by the expansion sections 52 on both sides, so that the wrinkles in the concave gap area are compressed; and insulation sheets 5 are arranged on both sides of the expansion section 52 31. The heat-insulating sheets 531 on both sides of the recessed area are squeezed toward the middle as the volume of the corresponding expansion section 52 increases, so that the wrinkled part of the fabric tube 4 located in the recessed gap area is squeezed by the heat-insulating sheets 531 on both sides. On the one hand, the gap of the wrinkled part is reduced under the squeezing effect and tends to be flat, so as to be in better contact with the skin surface; on the other hand, the heat-insulating sheets 531 are made of wool and have excellent heat-insulating properties, so as to better prevent the heat of the human body from being lost to the outside from the gap of the recessed part, so as to better protect the wearer under cold external conditions.

[0059] Embodiment five:

[0060] On the basis of the fourth embodiment, the filling section 53 is filled with antibacterial particles, and the surface of the filling section 53 is provided with breathing holes 532; and the outer surface of the expansion section 52 is provided with an extrusion protrusion 54, and the end of the extrusion protrusion 54 is embedded in the antibacterial particles; the breathing holes 532 are concentrated in the gap between the surface of the filling section 53 and the insulation sheet 531.

[0061] Specific workflow: Based on the specific workflow in Example 4, because the convex guide pleat portion of the expansion segment 52 is concentrated in the concave gap area between adjacent expansion segments 52; therefore, the air exchange between the inside and outside of the jacket at the collar 2 is mainly through the concave gap area; when the air passes through the concave gap area, the filling segment 53 is pressed as the wearer moves, and the air inside the filling segment 53 is strengthened to be exchanged through the breathing holes 532; and the breathing holes 532 are concentrated in the concave gap area, and the filling segment 53 is filled with antibacterial particles, so when the airflow is exchanged through the concave gap area, part of the airflow will enter the filling segment 53 and contact the antibacterial particles, so that the airflow passing through the concave gap area is sterilized by the antibacterial particles, thereby improving the sanitary environment between the skin and the tension rope 5 and the cloth tube 4, inhibiting the reproduction of bacteria in sweat, and improving the safety of the wearer;

[0062] In addition, an extrusion protrusion 54 is arranged inside the expansion section 52, and the end of the extrusion protrusion 54 is embedded in the filled antibacterial particles. As the wearer moves and squeezes the filling section 53, the end of the extrusion protrusion 54 stirs the antibacterial particles inside the filling section 53, so that the internal antibacterial particles flow with each other, avoiding aggregation and agglomeration, and ensuring the contact between the antibacterial particles and the airflow exchanged through the breathing hole 532; and as the filling section 53 is compressed, the end of the extrusion protrusion 54 bulges and contacts the side wall of the filling section 53, so that the surface of the filling section 53 corresponding to the end of the extrusion protrusion 54 bulges, so that the wrinkles in the gap area are further squeezed, and the relative friction between the tensioning rope 5 and the cloth tube 4 is enhanced, thereby preventing the vibration effect when the wearer moves, causing the tensioning rope 5 to slide and dislocate in the cloth tube 4, affecting the closed insulation of the collar 2 of the jacket.

[0063] Embodiment six:

[0064] On the basis of the fifth embodiment, the extrusion protrusion 54 is made of elastic material, the interior of the extrusion protrusion 54 is hollow and communicates with the interior of the expansion section 52 ; the end of the extrusion protrusion 54 is bent toward the direction close to the support section 51 .

[0065] Specific working process: Based on the specific working process in Example 5, as the expansion section 52 inside the fabric tube 4 is inflated, a part of the air flows into the extrusion protrusion 54, causing the extrusion protrusion 54 to inflate and expand, and as the volume of the expansion section 52 connected to the extrusion protrusion 54 increases, the end of the extrusion protrusion 54 moves toward the recessed gap between the expansion sections 52 on both sides, and squeezes the corresponding insulation sheet 531 to further compress the recessed gap, thereby reducing the size of the pleat gap in the recessed gap, further preventing the airflow from being exchanged through the pleat gap in the recessed gap, reducing heat loss, and better protecting the wearer's safety in a cold external environment.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
