Description

Technical Field

[0001] This invention relates to the field of search and rescue protection technology, and more specifically, to a multifunctional search and rescue protective garment. Background Technology

[0002] In scenarios such as fire rescue, outdoor search and rescue, and emergency disaster relief, rescuers face complex dangers such as high-temperature flames, sharp object punctures, and low-visibility obstacles, placing extremely high demands on the performance of search and rescue protective clothing. However, current traditional search and rescue protective clothing generally suffers from limited functionality, insufficient practicality, and poor comfort, making it difficult to meet the diverse needs of actual search and rescue work.

[0003] However, most existing search and rescue protective clothing only offers basic abrasion resistance and flame retardancy, failing to protect against sharp objects. Some added protective structures are fixed designs, hindering movement and increasing costs, and lack specific joint protection. Functionally, there are no effective positioning and warning structures in low-visibility environments, and emergency supplies must be carried separately or stored together, making them inconvenient to access. In terms of comfort, the fabrics have poor breathability and moisture absorption, the fixed fit lacks adjustability, and some sealed designs exacerbate stuffiness. Furthermore, components have poor compatibility, are difficult to disassemble and assemble, and critical structures are easily damaged during cleaning, shortening their lifespan. Summary of the Invention

[0004] This invention provides a multifunctional search and rescue protective garment to solve the problem that existing search and rescue protective garments lack adaptive adjustment functions when protecting the legs of search and rescue personnel, which can easily affect the mobility of search and rescue personnel when wearing protective clothing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multifunctional search and rescue protective garment includes a garment body, which integrates a protective module, a search and rescue auxiliary module, and a comfort adjustment module. A ventilation window is opened on the outer side of the lower garment 2 of the garment body. A protective component is installed on the inner side of the lower garment body below the horizontal height of the ventilation window. The protective component includes an airtight cover 3 installed on the inner side of the lower garment body. Multiple ventilation slots are formed on the side wall of the airtight cover 3. The top of the airtight cover 3 is connected to the garment body via multiple connecting blocks, each connecting block being separated by an air inlet. A telescopic pad is provided on the inner top wall of the airtight cover 3, and an elastic ring is provided on the inner side of the telescopic pad. A retaining ring is slidably engaged on the outer side of the top of the airtight cover 3, and multiple notches are formed on the outer side of the retaining ring. The notches are aligned vertically with the connecting blocks. A control plate is provided on the outer side of the airtight cover 3. An electromagnet and a magnetic block are arranged between the control plate and the opposite end of the retaining ring. A pressure sensor is connected to the bottom of the lower garment body via a wire, and the pressure sensor controls the electromagnet to switch on and off.

[0007] Preferably, the outer sides of the two sets of ventilation slots are provided with connecting plates, and the connecting plates are connected to the airtight cover by elastic plates. A slider is provided on the outer side of the connecting plate, and the slider is slidably locked in the longitudinal groove opened in the side wall of the airtight cover. A protrusion is connected to the outer side of the slider at the bottom end, and a pull rope is connected to the bottom end of each of the two protrusions. A guide clip is provided on the outer side of the airtight cover, and the pull rope passes through the guide clip. The free ends of the two pull ropes are connected to a movable frame, and the top of the movable frame is connected to the side plate provided on the outer side of the airtight cover by a spring. The inner side of the bottom end of the movable frame contacts the bottom end of the limiting plate.

[0008] Preferably, the garment body is the core load-bearing structure, made of high-strength abrasion-resistant and flame-retardant fabric. The high-strength abrasion-resistant and flame-retardant fabric, through a special fiber blending process, can resist friction and scratch damage, and can form a flame-retardant barrier when a flame approaches, avoiding high-temperature burns. The outer layer of the garment body is additionally provided with a puncture-proof and cut-proof protective layer, the inner layer of the garment body is composite with a breathable and moisture-wicking lining, and a protective module is provided on the garment body.

[0009] Preferably, the protective module includes the detachable shoulder pads, elbow pads, and knee pads, which are fixed to the corresponding positions of the garment body by Velcro and snaps. The detachable shoulder pads, elbow pads, and knee pads have a built-in double-layer protective structure: one layer is a cushioning and shock-absorbing material, and the other layer is a puncture-resistant core layer.

[0010] Preferably, the search and rescue assistance module includes reflective warning strips sewn onto the chest, back, and outer arms of the garment. These reflective warning strips can reflect ambient light at night and in low-visibility environments, helping teammates or trapped individuals quickly identify the location of rescuers. An LED positioning light is mounted on the back of the garment, supporting both constant and flashing modes.

[0011] Preferably, the garment body has an emergency communication interface fixedly located on the left chest position, which can be directly connected to a walkie-talkie or satellite phone; the garment body also has portable storage bags on both sides and the back, each of which is layered and separated by waterproof material, and contains a first aid kit, pliers, and spare batteries.

[0012] Preferably, the comfort adjustment module includes an elastic waistband located at the waist of the garment body, and an adjustable elastic band is provided on the outside of the elastic waistband, with the two ends of the elastic band connected by buckles and slots.

[0013] Preferably, the cuff of the garment body has an opening on the side, and the outer side of the cuff of the garment body is provided with an adjustable Velcro. The adjustable Velcro can freely control the size of the cuff opening, preventing dust and rainwater from entering the garment, and is also compatible with the wearing of rescue gloves.

[0014] Preferably, the garment body has breathable zippers under the armpits of the top and on the inner thighs of the pants. Opening the zipper creates an air convection channel, and an isolation mesh is provided on the inside of the breathable zipper.

[0015] The principle and beneficial effects of this technical solution:

[0016] (1) In terms of protective performance, this invention effectively overcomes the shortcomings of traditional clothing protection, which is limited by its single and fixed nature. The outer layer of the garment is equipped with a puncture- and cut-resistant protective layer, and is paired with detachable shoulder pads, elbow pads, and knee pads (with built-in cushioning and shock-absorbing materials and a puncture-resistant core layer). This provides dual protection for the torso and joints, resisting puncture and impact injuries from sharp objects. Furthermore, the detachable design with Velcro and snaps avoids restricting movement due to fixed protective structures, and allows for the individual replacement of damaged parts, reducing usage costs and providing comprehensive and flexible safety protection for rescue personnel.

[0017] (2) The protective components in this invention can be dynamically adjusted according to the current movement status of the search and rescue personnel. When the user needs to maintain the breathability of the clothing, air can be injected into the lower garment through the opening at the knee joint to maintain the breathability of the clothing. When the clothing needs to maintain its protective performance, the connection between the inner layer of the lower garment and the outside can be closed, so that the clothing can adjust the inflation and deflation status of the lower garment layer in real time according to the user's movement status, so as to ensure the protective effect while reducing the impact on the movement ability of the search and rescue personnel.

[0018] (3) In terms of practicality and comfort, this invention completely solves the problems of lack of function and discomfort in traditional clothing. The search and rescue auxiliary module integrates reflective warning strips and LED positioning lights, which can clearly identify the location of rescuers in low visibility environments and avoid losing contact; the emergency communication interface and layered portable storage bag ensure stable connection of communication equipment, classified storage of emergency supplies and convenient access, greatly improving the efficiency of search and rescue coordination; the elastic waistband, adjustable cuffs and breathable zipper of the comfort adjustment module can not only adapt to different body types, but also relieve stuffiness through air convection, taking into account both fit and breathability, solving the problems of poor breathability and fixed pattern of traditional fabrics, and ensuring the comfort of rescuers during long-term operations.

[0019] (4) This invention also optimizes component compatibility and maintenance convenience. Both the thermal liner and the protective module can be easily disassembled and assembled, and can be flexibly adjusted according to different temperature and risk levels to adapt to diverse search and rescue needs. After use, each component can be separated for cleaning to avoid damage to key structures (such as reflective strips and protective layers) and extend the service life of the clothing. Overall, this invention takes into account comprehensive protection, functional practicality, wearing comfort and scene adaptability, and can provide all-round protection for rescuers, significantly improve the safety and efficiency of search and rescue work, and promote the performance upgrade of search and rescue equipment.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] Example:

[0027] A multifunctional search and rescue protective garment includes a garment body integrating a protective module, a search and rescue auxiliary module, and a comfort adjustment module. A ventilation window 1 is opened on the outer side of the lower garment 2. A protective component is installed on the inner side of the lower garment 2 below the horizontal height of the ventilation window 1. The protective component includes an airtight cover 23 installed on the inner side of the lower garment 2. Multiple ventilation slots 7 are opened on the side wall of the airtight cover 23. The top of the airtight cover 23 is connected to the lower garment 2 via multiple connecting blocks 8, with ventilation channels between each connecting block 8. Separated by the air inlet 9, the inner top wall of the airtight cover 23 is provided with a telescopic pad 4, and the inner side of the telescopic pad 4 is provided with an elastic ring 5. The outer side of the top of the airtight cover 23 is slidably fitted with a retaining ring 10, and the outer side of the retaining ring 10 is provided with multiple notches 6. The position of the notches 6 is aligned with the connecting block 8 in the vertical direction. The outer side of the airtight cover 23 is provided with a control plate 11. An electromagnet and a magnetic block are provided between the control plate 11 and the opposite end of the retaining ring 10. The bottom of the garment body 2 is connected to a pressure sensor through a wire. The pressure sensor controls the electromagnet to turn on and off.

[0028] Two sets of ventilation slots 7 are equipped with connecting plates 19 on their outer sides. The connecting plates 19 are connected to the airtight cover 23 by elastic plates. A slider 13 is provided on the outer side of the connecting plates 19. The slider 13 is slidably locked in the longitudinal groove 12 opened in the side wall of the airtight cover 23. A protrusion 18 is connected to the outer side of the slider 13 at the bottom end. A pull rope 20 is connected to the bottom end of each of the two protrusions 18. A guide clip 21 is provided on the outer side of the airtight cover 23. The pull rope 20 passes through the guide clip 21. The free ends of the two pull ropes 20 are connected to a movable frame 16. The top of the movable frame 16 is connected to the side plate 14 provided on the outer side of the airtight cover 23 by a spring 15. The inner side of the bottom end of the movable frame 16 contacts the bottom end of the limiting plate 17.

[0029] This protective component provides impact protection for the legs of rescue personnel and enhances the protective effect of the garment itself when no protection is needed. When the protective component is required, the pressure sensor is activated and fixed inside the rescuer's shoe. When the pressure sensor detects pressure, the rescuer's leg is in the stepping position after lifting the leg. At this time, the pressure sensor controls the electromagnet to close, and the retaining ring will fall under the action of gravity, preventing the retaining ring from pressing against the connecting block. The air inlet between the connecting blocks remains open, and air will rush into the garment through the ventilation window during the rescuer's stepping process. The air is then ventilated, dried, or cooled through the ventilation slots on the side wall of the airtight cover.

[0030] When the ventilation slot needs to be opened, open the sealing ring at the bottom of the airtight cover, manually move the moving frame to make the moving frame fit and fix it to the upper surface of the sealing ring. At this time, the moving frame will pull the two connecting plates and the ventilation slot through the pull rope, and the ventilation slot will be in the open state. When the ventilation slot needs to be closed, release the fixing between the moving frame and the upper surface of the sealing ring, and the elastic plate will drive the connecting plate to reset and close the ventilation slot.

[0031] When the pressure sensor does not detect pressure, it indicates that the rescuer is in a leg-raising position. At this time, the pressure sensor will control the electromagnet to open, and the electromagnet will drive the retaining ring to move up and close the air inlet. If the ventilation channel is closed at this time, a sealed space can be formed inside the airtight cover to protect the rescuer's lower limbs from impact.

[0032] The garment itself serves as the core load-bearing structure, made of high-strength, abrasion-resistant, and flame-retardant fabric. This fabric, through a special fiber blending process, can resist friction and scratch damage and form a flame-retardant barrier when flames approach, preventing high-temperature burns. The outer layer of the garment also features an additional puncture-proof and cut-proof protective layer, which can effectively prevent sharp objects (such as broken glass and metal fragments) from penetrating the fabric, protecting the torso of rescue personnel.

[0033] The inner layer of the garment is made of a breathable and moisture-wicking lining that can quickly absorb the moisture produced by the body's sweat and expel it outwards, avoiding discomfort caused by stuffiness from prolonged wear and providing rescuers with a continuously dry wearing experience. The garment itself is equipped with protective modules.

[0034] The protective module includes detachable shoulder pads, elbow pads, and knee pads. The detachable shoulder pads, elbow pads, and knee pads are fixed to the corresponding positions of the garment body by Velcro and snaps, which is convenient for daily cleaning and individual replacement of damaged parts, and can fit closely to the joint curves during use without affecting limb movement.

[0035] The detachable shoulder, elbow, and knee pads are secured to the garment via Velcro and snaps. These pads feature a double-layered protective structure: one layer is a cushioning and shock-absorbing material that absorbs impact during falls and collisions, reducing shock damage to joints; the other layer is a puncture-resistant core that protects against direct punctures from sharp objects. This makes them particularly suitable for scenarios involving access to sharp objects, such as rubble search and rescue or jungle rescue, providing double protection for critical areas like the shoulders, elbows, and knees.

[0036] The search and rescue assistance module includes reflective warning strips sewn onto the chest, back, and outer arms of the garment. These reflective warning strips can reflect external light at night and in low-visibility environments, helping teammates or trapped individuals quickly identify the location of rescuers.

[0037] The back of the garment is equipped with an LED positioning light, which supports both constant and flashing modes. Rescue personnel can switch between these modes according to the lighting conditions on site to further expand the positioning range, facilitating team coordination and command and dispatch.

[0038] An emergency communication interface is fixedly installed on the left chest of the garment, which can be directly connected to a walkie-talkie or satellite phone to prevent the loss or damage of communication equipment due to careless placement and to ensure uninterrupted communication during rescue operations.

[0039] The garment also features portable storage pockets on both sides and the back. These pockets are layered and separated by waterproof material. They contain first-aid kits, pliers, and spare batteries, allowing rescuers to quickly access these items, reducing search time and improving search and rescue efficiency.

[0040] The comfort adjustment module includes an elastic waistband at the waist of the garment, with an adjustable elastic band on the outside. The two ends of the elastic band are connected by buckles and slots, allowing rescuers to adjust the tightness according to their waist size. This ensures that the garment fits the torso and reduces fabric movement during movement, while also accommodating inner garments of different thicknesses.

[0041] The garment has an opening on the side of the cuff, and an adjustable Velcro closure on the outside of the cuff. The adjustable Velcro closure allows for free control of the size of the cuff opening, preventing dust and rain from entering the garment, and also accommodates the wearing of rescue gloves.

[0042] The garment features breathable zippers under the armpits of the top and on the inner thighs of the trousers. When rescuers are engaged in high-intensity work and their bodies are hot and sweaty, opening the zippers creates air convection channels, quickly lowering the internal temperature of the garment and alleviating stuffiness. When the zippers are closed, the garment remains waterproof, making it suitable for various search and rescue environments such as rain and humidity. The inside of the breathable zippers is also equipped with a mesh screen.

[0043] This garment combines protective performance, search and rescue practicality, and wearing comfort. It can effectively resist physical damage in complex environments (such as punctures, cuts, impacts, and high temperatures), while improving safety and operational efficiency during search and rescue through functions such as positioning, communication, and storage. It is suitable for various scenarios such as fire rescue, outdoor search and rescue, and emergency rescue.

[0044] The specific usage and function of this embodiment are as follows:

[0045] Clothing preparation: Depending on the temperature at the search and rescue site, decide whether to add a thermal liner to the clothing itself. If the environment is cold, fix the liner to the inside of the jacket with buttons, then put on the clothing normally, fastening the collar and zipper.

[0046] Protective module assembly: Depending on the risk level of the search and rescue scenario, if joint protection is required, align the shoulder pads, elbow pads, and knee pads with the shoulder, elbow, and knee positions respectively, secure them with Velcro, and then fasten the snaps to ensure stability and prevent them from falling off during movement; if the scenario risk is low, the protective modules can be removed to reduce the weight of the clothing.

[0047] Activating the search and rescue assistance module: After putting it on, check that the reflective warning strip is flat and wrinkle-free to ensure reflective effect; press and hold the LED positioning light switch on the back to start the device, and select the constant light (strong light environment) or flashing (weak light environment) mode according to the ambient light; connect communication devices such as walkie-talkies to the emergency communication interface on the chest to ensure normal signal; sort and put first aid kits, tools and other supplies into the portable storage bag, and zip it up to prevent loss.

[0048] Comfort adjustment: Adjust the elastic waistband and Velcro cuffs according to your body shape to make the garment fit the body without restricting movement; if you feel stuffy during work, unzip the ventilation zippers under the armpits and inside the thighs to cool down through air convection. After cooling down, you can close the zippers to maintain waterproofness.

[0049] Post-use handling: After the search and rescue operation, first remove the protective module and the inner liner and clean them separately; turn off the LED positioning light and charge it, disconnect the communication equipment and put it away; the garment itself can be cleaned according to the degree of contamination. When cleaning, avoid rubbing the reflective warning strip and the protective layer vigorously to ensure that all components can be used normally in the future.
