Description

Technical Field

[0001] This invention relates to a protective garment with an internal suspension bracket that allows for ventilation and can block solar heat radiation, belonging to the field of protective garment technology. Background Technology

[0002] Due to the continuous rise in global sea temperatures, glaciers are melting at an accelerated pace. This summer, many parts of my country have experienced a rare "heat dome" phenomenon, with some areas experiencing 9 to 19 consecutive days of extremely high temperatures, reaching extreme values ​​of 45 degrees Celsius. C; In addition, many areas were hit by sudden subtropical high-pressure airflows, bringing severe conditions of high temperature and high humidity at the same time; these prolonged periods of extremely high temperature are caused by extremely strong solar thermal radiation energy; which poses a great threat to the health of people who are active outdoors.

[0003] Regarding the use of aluminum foil in protective clothing, our investigation has revealed that no officially licensed products are currently available on the market. For information on the thermal insulation properties of aluminum foil, please refer to the following document:

[0004] Book title: Aluminum Foil Thermal Insulation Materials and Their Applications - by Huang Qiming First edition published by Zhejiang Science and Technology Press, February 1985. Section 6 Thermal Insulation Properties of Nameplate Foil Emissivity of three-dimensional foil The thermal insulation properties of foil are manifested in the thermal radiation characteristics of its surface. Aluminum is a metal with extremely poor temperature radiation properties. Polished aluminum surfaces can be viewed as white bodies that do not emit or absorb thermal radiation, which can be explained from the perspective of quantum mechanics.

[0005] Thermal radiation can freely penetrate the surrounding dry air without producing a direct effect. It can only raise the temperature of objects that absorb radiation instead of reflecting it. ...In metals, electrons have an energy level distribution. Exciting an electron from a bound state to a conduction state requires energy absorption, and when the electron is captured again and returned to a bound state, this energy is released. Aluminum has a large energy level difference between its free electrons, and its atoms do not easily emit quanta. When exposed to external thermal radiation, energy is not easily captured by bound electrons. Therefore, aluminum foil has particularly low absorption and emission of radiation energy. Due to the emissivity of aluminum foil... The value is very close to its absorption rate α, so the aluminum foil is regarded as a gray body in thermal calculations.

[0006] Polished aluminum surface, ε=0.02~0.06. Summary of the Invention

[0007] The technical problem to be solved by this invention is: how to innovate the design of traditional tops used in people's daily lives so that the tops can be ventilated and can block solar heat radiation.

[0008] Because aluminum foil material has two significant properties, 1) The bright side of aluminum foil has very low absorption and emission of thermal radiation energy, with an absorptivity and emissivity of approximately 0.02~0.06; 2) Aluminum foil is produced through rolling and has high toughness; these two characteristics provide favorable conditions for the innovative design of protective clothing.

[0009] To solve the above-mentioned technical problems, based on the two significant characteristics of aluminum foil, the technical solution of the present invention is to provide a protective garment with an internal suspension bracket that allows for ventilation and can block solar heat radiation. The garment is characterized by comprising a main body made of aluminum foil fabric, an internal suspension bracket, sleeves, shoulder padding straps, a collar, buttons, and pockets. Multiple vertically arranged internal suspension brackets are evenly distributed on the inner side of the main body, with gaps between corresponding internal suspension brackets in the lateral direction to form channels for upward airflow. Lateral cuts for arm extension are provided at the shoulders on both sides of the main body, and shoulder padding straps are provided on the inner side of the main body at the shoulder position.

[0010] The multi-segment internal suspension bracket is mainly designed to provide comfort when bending over and moving the arms, as well as comfort for the protruding parts of the body's muscles.

[0011] Preferably, the two sides of the garment body are respectively connected to sleeves made of aluminum foil. The upper part of the sleeve is connected to the side break of the aluminum foil on the garment body at the shoulder. Multiple inner suspension brackets are also evenly distributed on the inner side of the sleeve. The sleeve is cylindrical. The inner suspension brackets on the inner side of the sleeve are divided into two parts: one part is where the upper arm is located, and the other part is where the forearm is located. No inner suspension bracket is set at the elbow position, and no suspension bracket is set on the side of the upper arm near the body.

[0012] Preferably, a ventilation hole is provided at the connection seam between the upper part of the sleeve and the lower side of the lateral break.

[0013] Preferably, each of the inner suspension brackets consists of a central suspension rod and two positioning seats at both ends. The two positioning seats are connected by the suspension rod, and the inner suspension bracket is fixed to the inner side of the aluminum foil cloth via the positioning seats at both ends. By setting the inner suspension bracket on the inside of the aluminum foil cloth, an air gap is formed between the inner bright surface of the aluminum foil cloth and the human skin, allowing approximately 98% of the inner bright surface of the aluminum foil cloth to be suspended. Therefore, the thermal radiation characteristics of the bright surface of the aluminum foil can be fully utilized, and the insulation efficiency of the bright surface of the aluminum foil against thermal radiation energy can be greatly improved.

[0014] Preferably, each positioning seat has positioning plates on both ends, and the two positioning plates are connected by a vertical plate. A pre-drilled hole for connecting a suspension rod is provided in the middle of the vertical plate, and there is a gap between the suspension rod and the inner surface of the aluminum foil. The suspension rod can be straight or curved.

[0015] Preferably, a shoulder padding strap is connected to the inner side of the inner suspension bracket located at the shoulder position inside the garment body.

[0016] Preferably, the shoulder padding strap is provided with a loop at the lateral break connection point between it and the main body of the garment. The shoulder padding strap opens at the chest seam, and its opening is connected to the aluminum foil fabric of the main body at the left and right openings of the seam, respectively, forming an open state. One side of the inner suspension bracket is fixedly connected to the aluminum foil fabric, and the other side is fixedly connected to the shoulder padding strap. The entire weight of the main body of the garment and all inner suspension brackets is concentrated and transferred to the shoulders by the inner suspension bracket connected to the shoulder padding strap at the upper part of the main body.

[0017] Preferably, the top of the garment body is connected to a collar made of aluminum foil, with the collar opening facing forward and the back collar higher than the front collar; the front collar is split; the collar has a vertical upward structure, extending upward from the aluminum foil of the garment body. The collar is arc-shaped, with a large gap between the collar and the neck, which serves as the main exhaust vent for guided natural ventilation inside the garment body.

[0018] Preferably, the outer side of the garment body has buttons arranged vertically in the middle; and the outer side of the garment body has pockets at the upper or lower part.

[0019] Preferably, the aluminum foil cloth includes aluminum foil and a support cloth. The aluminum foil is divided into a bright side and a dark side. The bright side is the functional side, and the dark side is the bonding side with the support material. The aluminum foil is combined with colored plain weave cloth to form aluminum foil cloth.

[0020] Regarding the thermal insulation properties of aluminum foil, the structural design is based on the theory of quantum mechanics. Experiments on the transfer of thermal radiation energy of aluminum foil show that when the bright side of the aluminum foil transfers radiant heat energy to human skin through the air gap, it is a "wave-state heat transfer", and the insulation efficiency of the aluminum foil is very high.

[0021] The protective clothing of this invention employs guided natural ventilation. Its mechanism follows three factors of airflow: 1) temperature, 2) pressure, and 3) density. Air flows due to changes in temperature, pressure, and density. Regarding radiative heat transfer, it is mainly influenced by the sun's movement, rising in the morning and setting in the evening in a cyclical pattern. Solar radiation irradiates the ground, and the ground absorbs this radiation, raising the surface temperature and the temperature of the air above it. Under continuous solar radiation, the ground temperature continues to rise. Simultaneously, the air above the ground continuously flows upwards, forming wind. Since thermal radiation has no effect on wind, this wind is one of the power sources for the protective clothing's natural ventilation, enhancing the flow speed of guided natural ventilation. Therefore, when people wear the protective clothing outdoors, the flowing air naturally enters the airflow channel from the lower air inlet of the clothing body, flows upwards along the ventilation channel over the body surface, and rises to the collar exhaust port before being discharged into the atmosphere. People experience a particularly cool feeling, like being under the shade of a tree with a breeze blowing on their skin.

[0022] The inventiveness of this invention is as follows: The inner suspension bracket on the inside of the aluminum foil cloth consists of a central suspension rod and positioning seats at both ends. The suspension bracket is fixed to the inner surface of the aluminum foil cloth via the positioning seats at both ends, and is arranged in multiple vertical segments. The suspension rod is installed in the pre-drilled hole in the middle of the vertical plate of the positioning seats at both ends. There is a gap between the suspension rod and the inner surface of the aluminum foil cloth. Natural ventilation is guided by the airflow channels between the vertically arranged inner suspension brackets on the inner surface of the aluminum foil cloth. By setting the inner suspension bracket on the inside of the aluminum foil cloth, about 98% of the inner bright surface of the aluminum foil cloth can be suspended, and an air gap can be formed between the inner bright surface of the aluminum foil cloth and human skin. Therefore, the thermal radiation characteristics of the bright surface of the aluminum foil are fully utilized, which can greatly improve the insulation efficiency of the aluminum foil cloth against thermal radiation energy.

[0023] Compared with the prior art, the present invention has the following beneficial effects.

[0024] Under intense solar radiation, people wearing protective clothing made of aluminum foil, along with guided natural ventilation, experience a uniquely cool feeling when they are in the shade of trees and the wind is blowing on their bodies. Attached Figure Description

Detailed Implementation

[0026] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] This invention provides a protective garment with an internal hanging bracket that allows for ventilation and insulation against solar heat radiation, such as... Figures 1-4 As shown, it includes an inner hanging bracket 7, a garment body 1, a collar 2, sleeves 4, buttons 3, pockets 5, and shoulder padding straps 8. The main body of the garment body 1 is made of aluminum foil cloth 6. The top of the garment body 1 is connected to the collar 2. The two sides of the garment body 1 are connected to the sleeves 4 respectively. The inner sides of the garment body 1 and the sleeves 4 are connected to the inner hanging bracket 7. The outer middle of the garment body 1 has buttons 3 arranged vertically. The upper or lower part of the outer side of the garment body 1 has pockets 5. The lower side of the shoulder of the garment body 1 has shoulder padding straps 8.

[0028] Aluminum foil fabric 6 is the main material for the outer side of the garment. The main body 1, collar 2, and sleeves 4 are all made of aluminum foil fabric 6. Aluminum foil fabric 6 includes aluminum foil and a backing fabric. The aluminum foil has two sides: a shiny side and a dark side. The shiny side is the functional side, and the dark side is the side that bonds with the backing material. The aluminum foil can be combined with colored plain weave fabric to form aluminum foil fabric 6. The production of the main body 1 using aluminum foil fabric 6 can refer to the traditional cutting and sewing processes and methods for garments, while also taking into account the characteristics of the aluminum foil fabric material.

[0029] The production of collar 2 is quite special because collar 2 is the main exhaust outlet at the top of the protective clothing for guided natural ventilation. Since the human neck is approximately cylindrical, vertically upward, and about 100mm in diameter, collar 2 has an opening facing forward, with a back collar height of about 30mm and a front collar height of about 10mm. The front collar is split, with an opening width of about 30mm. Collar 2 is located on the outer periphery of the neck, vertically upward, with about 20mm between collar 2 and the neck. Collar 2 extends upward from the aluminum foil fabric 6 of the main body 1.

[0030] The function of sleeve 4 is to protect the upper arm and forearm. The elbow is located between the upper arm and forearm. The elbow is a key joint that controls the movement of the upper arm and forearm. Sleeve 4 is symmetrical from left to right. The upper part of sleeve 4 is connected to the side break 9 of aluminum foil cloth at the shoulder. Sleeve 4 is cylindrical and is connected to the body of the garment 1 on the side close to the body. Ventilation holes can be set at the connection seam on the lower side of the upper part of the sleeve tube.

[0031] The inner suspension brackets 7 inside the garment body 1 are arranged vertically in multiple segments, forming a unified structure. The outer sides of all the inner suspension brackets 7 inside the garment body 1 are wrapped with aluminum foil 6. There are gaps between the lateral positions of the inner suspension brackets 7 inside the aluminum foil 6, forming channels for upward airflow.

[0032] The sleeve 4 includes an outer aluminum foil 6 and an inner suspension bracket 7 on the inner side of the aluminum foil 6. The inner suspension bracket 7 on the inner side of the sleeve 4 is divided into two sections: the upper section is where the upper arm is located, and the lower section is where the forearm is located. The inner suspension bracket 7 cannot be set at the elbow position. The inner suspension bracket 7 of the sleeve 4 is an integral structure composed of multiple brackets and extends along the length of the arm.

[0033] The main function of button 3 is to lock the front opening of the garment. Since button 3 may cause localized damage to the aluminum foil fabric 6, a protective covering can be used (i.e., covering the edge of the buttonhole on the garment body 1 with a protective film or multiple layers of stitching). The material of button 3 should be non-metallic, such as plastic or smooth acrylic.

[0034] Pocket 5 is an essential part of the garment, designed to hold essential small personal items. The stress-bearing anchor point is located on the aluminum foil fabric. A cover should be installed at the connection point between pocket 5 and the main body 1 for protection. Traditional manufacturing methods can be referenced.

[0035] like Figure 5 As shown, the inner suspension bracket 7 consists of a central suspension rod 72 and two positioning seats 71 at both ends. Each positioning seat 71 has a positioning plate on both ends, and the two positioning plates are connected by a vertical plate. A pre-drilled hole for connecting the suspension rod 72 is provided in the middle of the vertical plate. The inner suspension bracket 7 is fixed to the inner surface of the aluminum foil cloth 6 via the positioning seats 71 at both ends. The positioning seats 71 are connected to the aluminum foil cloth 6 via the positioning plates. Each inner suspension bracket 7 is arranged in a vertically multi-segment configuration. The two ends of the suspension rod 72 are installed in the pre-drilled holes in the middle of the vertical plates on the two positioning seats 71. The positioning seats 71 are symmetrical about the suspension rod 72. There is a gap between the suspension rod 72 and the inner surface of the aluminum foil cloth 6.

[0036] By setting a hanging bracket 7 on the inside of the aluminum foil cloth 6, about 98% of the inner bright surface of the aluminum foil cloth 6 can be suspended, which can form an air gap between the inner bright surface of the aluminum foil cloth 6 and human skin. Therefore, the thermal radiation characteristics of the aluminum foil surface can be fully utilized, and the insulation efficiency of the aluminum foil bright surface against thermal radiation energy can be greatly improved.

[0037] The positioning seat 71 can be made of thin plastic tubing, with an I-shaped structure. The upper and lower seat plates are identical. The seat plate is approximately 10mm long, 8mm wide, and 0.8mm thick. The vertical plate is approximately 10mm high, 8mm wide, and 0.8mm thick. A pre-drilled circular hole with a diameter of approximately 4-6mm is pre-drilled in the center of the vertical plate. The positioning seat 71 is symmetrical from left to right, with the positioning opening facing outwards. The suspension rod 72 is installed in the pre-drilled hole in the center of the vertical plate of the positioning seat 71 and fixed with a locking pin. The suspension rod 72 has a diameter of approximately 4-6mm, a length of approximately 130mm, and a thickness of approximately 0.2mm. There is approximately a 3mm gap between the bottom of the suspension rod 72 and the inner side of the aluminum foil cloth 6.

[0038] The inner suspension bracket 7 located inside the main body of the garment 1 at the shoulder position is provided with a shoulder padding strap. Since the surface slope of the shoulder part changes greatly, the shoulder padding strap 8 can transfer the overall weight of the protective garment to the shoulder padding strap 8 through the suspension bracket 7 located inside the aluminum foil cloth 6 of the main body of the garment 1. The weight can be transferred to the shoulder through the shoulder padding strap 8. The shoulder padding strap 8 can ensure the stability of the entire protective garment when worn, and also facilitate the replacement of the protective garment.

[0039] The shoulder padding straps 8 are symmetrical. Additionally, loops are provided at the connection points between the shoulder padding straps 8 and the side breaks 9 of the sleeves 4. The shoulder padding straps 8 open at the chest seam, and these openings connect to the aluminum foil fabric 6 of the garment body 1 at the left and right openings of the seam seam, creating a left-right open state. The shoulder padding straps 8 are approximately 90mm wide front-to-back, made of silicone, and approximately 0.8mm thick. One positioning plate of the positioning seat 71 of the inner suspension bracket 7 is fixed to the aluminum foil fabric 6, and the other positioning plate is fixed to the shoulder padding straps 8.

[0040] The inner suspension bracket 7 in sleeve 4 is designed to accommodate the upper arm and forearm, with the elbow between them. Therefore, the inner suspension bracket 7 in sleeve 4 is designed to be installed in the upper part and the front part respectively, to ensure flexibility and comfort during elbow movement.
