Description

Technical Field

[0001] This invention relates to the field of pre-hospital emergency equipment technology, specifically to a multifunctional rainproof and slip-resistant emergency shoe for use in harsh pre-hospital emergency environments. Background Technology

[0002] Pre-hospital emergency care is characterized by its suddenness, environmental complexity, and urgency. As the frontline force of the emergency medical system, 120 emergency personnel often need to travel to various harsh environments, including mountainous areas, hilly terrain, muddy roads, slippery steps, unlit areas at night, and flooded roads, to conduct emergency calls. The practicality, safety, and suitability of their equipment directly affect emergency response efficiency and their own safety. Currently, the ordinary emergency shoes, work shoes, or general outdoor shoes commonly equipped by emergency personnel generally suffer from limited functionality and poor adaptability to different scenarios, making it difficult to meet the needs of emergency calls in complex and harsh environments. These pain points have long hindered the smooth operation of pre-hospital emergency care.

[0003] In terms of slip resistance, ordinary emergency shoes typically use conventional tread patterns and ordinary rubber materials on their soles, with a slip resistance coefficient generally below 0.6. When walking on wet, slippery tiles, icy surfaces, or muddy sections, the grip is severely insufficient, easily leading to slipping, ankle sprains, and other situations. This not only delays emergency treatment but may also cause injury to the emergency responders themselves. While some outdoor anti-slip shoes enhance grip, their tread patterns are not adapted to the rapid running, sudden stops, and turns required in emergency situations, and their excessive weight affects agility. Regarding rain and water resistance, existing emergency shoes mostly have a simple waterproof coating design, with a waterproof rating generally only IPX3-IPX4. This cannot withstand the impact of heavy rain or deep immersion in water. Rainwater can easily seep in through the seams of the upper, the shoe opening, and the gaps in the tongue, causing damp and cold feet, and even joint discomfort. At the same time, most waterproof shoes have extremely poor breathability, leading to stuffiness, sweating, and bacterial growth after prolonged wear, affecting foot health and wearing comfort.

[0004] In terms of shock absorption and protection, ordinary emergency rescue shoes lack targeted shock absorption structures, relying solely on the rubber sole for cushioning. After prolonged walking on rugged mountain roads and gravel sections, the feet are prone to fatigue due to continuous bumps and impacts, and may even lead to occupational injuries such as plantar fasciitis, restricting the continuous mobility of emergency responders. Furthermore, most shoes lack puncture-resistant designs, making them susceptible to punctures from sharp stones, metal shavings, branches, etc., in outdoor environments, causing foot injuries. Regarding nighttime safety warnings, existing emergency rescue shoes mostly lack dedicated warning structures, relying solely on reflective strips on emergency suits. At night, when responding to emergencies in unlit mountainous areas or remote sections, visibility is extremely low, increasing the risk of collisions with passing vehicles and pedestrians, posing a serious safety hazard.

[0005] While some manufacturers have launched improved shoes focusing on single functions, such as anti-slip work shoes and waterproof outdoor shoes, these cannot simultaneously meet multiple core requirements including anti-slip, rainproof, shock absorption, warning, puncture resistance, lightweight, and emergency suitability. Furthermore, they generally suffer from complex structural designs, excessive weight, unbalanced breathability, and insufficient adaptability, failing to meet the core demands of pre-hospital emergency personnel for "rapid action, prolonged wear, multi-scenario adaptability, and high safety." Therefore, there is an urgent need to design a professional emergency shoe that integrates multiple functions, is precisely adapted to the harsh environment of pre-hospital emergency care, and conforms to emergency work habits, filling the current technological gap and comprehensively improving the safety and work efficiency of emergency personnel. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional rainproof and anti-slip emergency shoe for use in harsh environments in pre-hospital emergency care. It solves the problems of insufficient anti-slip, rainproof, shock absorption, nighttime warning and emergency adaptability of existing emergency shoes in harsh environments. It integrates five major functions: anti-slip, rainproof, shock absorption, warning and portability, adapts to the needs of pre-hospital emergency care in all harsh environments, and improves the safety and convenience of emergency personnel.

[0007] To achieve the above objectives, the present invention employs the following technical means:

[0008] A multifunctional rainproof and slip-resistant emergency shoe for use in harsh environments in pre-hospital emergency care includes a sole, an upper, and a boot, wherein the upper and boot are integrally made and the upper is connected to the sole by a seamless hot-pressing edge sealing process;

[0009] The outsole includes a sole with a composite anti-slip pattern on its bottom surface. The composite anti-slip pattern includes anti-slip patterns distributed throughout the entire sole and biomimetic gecko claw patterns concentrated in the forefoot and heel impact zones. A puncture-resistant steel sheet layer is connected to the top of the sole, and a shock-absorbing layer is connected to the top of the puncture-resistant steel sheet layer. An elastic rebound pad is embedded in the bottom of the shock-absorbing layer at the heel.

[0010] A battery, a control switch, and a warning light are embedded in the heel of the shoe upper, and the warning light is connected to the battery through the control switch.

[0011] Reflective strips are attached to the sides and back of the shoe upper.

[0012] Preferably, the outsole is made of highly abrasion-resistant rubber, and the upper and upper are made of waterproof, breathable, highly elastic, and abrasion-resistant fabric with an elongation rate of ≥150%. The inner side of the upper and upper is lined with a breathable mesh interlayer to form a waterproof and breathable structure. The overall waterproof rating of the shoe body reaches IPX6, and the weight of the shoe body is controlled within 300 grams.

[0013] Preferably, the depth of the anti-slip texture is not less than 8mm.

[0014] Preferably, the damping layer is an EVA damping layer.

[0015] Preferably, the waterproof edging is a double-layer waterproof edging.

[0016] Preferably, the tightening band is a Velcro tightening band.

[0017] Preferably, the reflective strip is a 360° reflective product.

[0018] Preferably, the battery is a lithium battery, and the battery life is not less than 12 hours.

[0019] Preferably, the warning light is an LED warning light, which has two working modes: constant light and flashing light.

[0020] The present invention has the following beneficial effects:

[0021] 1. Significantly improved anti-slip and shock absorption performance, ensuring safe driving on complex road surfaces.

[0022] This invention overcomes the limitations of ordinary emergency shoes, such as low anti-slip coefficient and insufficient shock absorption. It employs a composite anti-slip pattern of "bionic gecko claw + deep interlaced teeth" combined with a medical-grade wear-resistant rubber sole, increasing the dynamic anti-slip coefficient to over 0.85, far exceeding existing ordinary emergency shoes. This effectively addresses various complex scenarios such as slippery tiles, icy roads, and muddy sections, significantly reducing the risk of slipping and ankle sprains. Simultaneously, the sole incorporates a honeycomb-shaped EVA shock-absorbing layer and an elastic rebound pad in the heel, along with a puncture-resistant steel plate layer. This provides efficient cushioning against the impact of bumps on rough terrain, reducing occupational injuries such as plantar fasciitis, while also resisting punctures from sharp objects. Balancing shock absorption and protection with mobility, it is suitable for emergency personnel's high-frequency dynamic movements such as running, stopping, and climbing, extending continuous working time.

[0023] 2. Fully enclosed waterproof and breathable structure, suitable for prolonged wear in humid and harsh environments.

[0024] Compared to the existing IPX3-IPX4 waterproof rating of emergency shoes, this invention upgrades the waterproof rating to IPX6 through multiple sealing designs, including seamless heat-sealed edges, double-layer waterproof edging, and an integrated tongue. This allows it to withstand heavy rain and deep water immersion, completely solving the problem of rainwater seeping in through seams, the shoe opening, and the tongue. Simultaneously, a breathable mesh interlayer is added to the inner side of the upper, allowing air circulation while maintaining all-around waterproofing. This avoids the drawbacks of existing waterproof shoes, such as poor breathability, stuffiness, sweating, and bacterial growth during prolonged wear, ensuring both foot dryness and health, and meeting the needs of long-duration emergency medical visits in humid and rainy environments.

[0025] 3. Dual nighttime warning design strengthens safety in low-visibility environments.

[0026] This invention fills the gap in existing emergency shoes by lacking a dedicated nighttime warning structure. It employs a dual warning solution of 360° reflective strips and LED warning lights. The reflective strips can reflect light from all directions, while the LED warning lights support both constant and flashing modes. Equipped with a built-in lithium battery, they can be controlled with a single button. Compared to existing methods that rely solely on reflective strips on emergency suits, this significantly improves visibility at night, in unlit mountainous areas, and on remote roads, expanding the warning range and effectively reducing the risk of collisions with passing vehicles and pedestrians. It provides dual safety assurance for emergency personnel responding to emergencies at night.

[0027] 4. Precisely adapted to emergency rescue scenarios, balancing practicality and lightweight design.

[0028] This invention optimizes the structural design based on the working habits of pre-hospital emergency care. The highly elastic upper can be flexibly adapted to protective boot covers, and the portable hooks on the side of the shoe facilitate the storage of small items such as emergency gloves and keys, improving work efficiency. The balanced combination of puncture-resistant steel sheet layer and lightweight materials achieves foot protection while keeping the overall shoe weight below 300g. This solves the problems of existing improved shoes being complex in structure, excessively heavy, and affecting mobility, thus meeting the core requirements of emergency personnel for rapid response and efficient action.

[0029] 5. The structure is stable and durable, and has broad application value.

[0030] This invention employs integrated upper and sole construction and seamless hot-press sealing processes, combined with highly wear-resistant and highly elastic materials, significantly improving the shoe's sealing performance and lifespan. It can withstand high-frequency use in harsh environments, reducing equipment replacement costs. Simultaneously, by integrating multiple functions such as anti-slip, rainproof, shock absorption, warning, puncture resistance, and lightweight design into a single product, it eliminates the need for emergency personnel to carry multiple specialized equipment, simplifying the preparation process. It can be widely applied in various fields such as 120 emergency services, wilderness rescue, and fire emergency rescue, possessing significant practical value and market potential, filling the technological gap in professional multi-functional shoes for pre-hospital emergency care.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-3 As shown, a multi-functional rainproof and slip-resistant emergency shoe for use in harsh environments in pre-hospital emergency care includes a sole 1, an upper 2, and an upper 3. The upper 2 and the upper 3 are made as one piece, and the upper 2 is connected to the sole 1 by a seamless hot-pressing edge sealing process.

[0038] The sole 1 includes a sole outsole 101. The bottom surface of the sole outsole 101 is provided with a composite anti-slip pattern. The composite anti-slip pattern includes anti-slip patterns 102 distributed throughout the sole and biomimetic gecko claw patterns 103 concentrated in the forefoot and heel impact zones. A puncture-resistant steel sheet layer 104 is connected to the top of the sole outsole 101. A shock-absorbing layer 105 is connected to the top of the puncture-resistant steel sheet layer 104. An elastic rebound pad 106 is embedded and connected to the bottom of the shock-absorbing layer 105 at the heel.

[0039] A battery 7, a control switch 8, and a warning light 9 are embedded and connected at the heel of the shoe upper 2. The warning light 9 is connected to the battery 7 through the control switch 8.

[0040] Reflective strips 6 are connected to the sides and back of the shoe upper 3.

[0041] The outsole 101 is made of highly abrasion-resistant rubber, while the upper 2 and the upper 3 are made of waterproof, breathable, highly elastic, and abrasion-resistant fabric with an elongation rate of ≥150%. The inner side of the upper 2 and the upper 3 is lined with a breathable mesh interlayer to form a waterproof and breathable structure. The overall waterproof rating of the shoe reaches IPX6, and the weight of the shoe is controlled within 300 grams.

[0042] The advantages of the above design are as follows: the highly abrasion-resistant rubber material allows the outsole of the 101 model to withstand the wear and tear of mountain gravel and sharp objects, extending the lifespan of the shoe and making it suitable for frequent use in harsh environments; the waterproof, breathable, highly elastic, and abrasion-resistant fabric combines waterproofness, abrasion resistance, and elasticity, with an elongation rate of ≥150%, allowing for flexible adaptation to the wearing of protective boot covers and the large-scale movements of emergency personnel such as running and turning, while preventing fabric damage; the inner breathable mesh interlayer achieves a balance between waterproofness and breathability, solving the problem of stuffiness and sweating in traditional waterproof shoes and ensuring comfort during long-term wear; the IPX6 waterproof rating can withstand heavy rain and water accumulation, covering most wet emergency response scenarios; and the lightweight design of less than 300 grams ensures that the integration of multiple functions does not hinder the rapid movement of emergency personnel, meeting the urgent needs of pre-hospital emergency care.

[0043] The depth of the anti-slip texture 102 is not less than 8mm.

[0044] The advantages of the above design are as follows: the anti-slip grooves 102 with a depth of 8mm or more can be deeply embedded in mud and gravel gaps to form a stable mechanical interlock, greatly improving the grip on complex road surfaces and preventing slipping on muddy and waterlogged sections in mountainous areas; compared to shallower grooves, deeper grooves are less likely to be blocked by mud and gravel, maintaining continuous anti-slip performance and reducing the frequency of cleaning the grooves during emergency rescue; adaptable to the anti-slip needs of different harsh scenarios, and when combined with the biomimetic gecko claw pattern 103, the overall anti-slip coefficient can be ≥0.85, ensuring safety during movement.

[0045] The damping layer 105 is an EVA damping layer.

[0046] The advantages of the above design are as follows: EVA material is lightweight, highly elastic, and has excellent cushioning properties. As a shock-absorbing layer, it can effectively absorb the impact of bumps on rough roads, reduce foot fatigue for emergency personnel after long periods of walking and climbing, and reduce the risk of occupational injuries such as plantar fasciitis. EVA material is easy to process into a honeycomb structure, and the balance between shock absorption and lightweight can be achieved by optimizing the pore size without adding extra weight to the shoe. It has strong chemical stability and good wear resistance, can adapt to long-term use in harsh environments, and is not easily deformed by compression or friction, maintaining a stable shock absorption effect.

[0047] Waterproof edging 4 is a double-layer waterproof edging.

[0048] The advantages of the above design are as follows: Compared with a single-layer edging, the double-layer structure forms a double waterproof barrier, which can effectively prevent mud and water from seeping in through the gaps at the shoe opening, making it especially suitable for muddy mountain areas, waterlogged sections, and other scenarios where mud is likely to splash; the double-layer edging can improve the fit to the ankle, while enhancing the stability of the shoe opening structure, preventing deformation and waterproof failure caused by prolonged wear or frequent activities; the inner layer can conform to the skin to improve comfort, while the outer layer strengthens the sealing performance, taking into account both practicality and wearing experience.

[0049] Tightening band 5 is a Velcro tightening band.

[0050] The advantages of the above setup are: the Velcro structure is easy to operate, allowing emergency personnel to quickly adjust the tightness to fit different ankle dimensions, and quickly complete the donning and securing process without delaying the emergency response time; after fitting the ankle, the shoe opening can be further tightened, and the double-layer waterproof edging enhances the sealing effect, preventing mud and water from seeping in; the Velcro is stable and wear-resistant, and does not easily fail after repeated opening and closing, and is lightweight, which does not affect the overall lightweight design of the shoe, making it suitable for the high-frequency use needs of emergency scenarios.

[0051] Reflective strip 6 is a 360° reflective product.

[0052] The advantages of the above setup are: 360° all-around reflectivity with no blind spots, so that no matter which direction the headlights or flashlights shine from, they can reflect strong light to form a conspicuous identification, which greatly improves visibility at night and in low-visibility environments compared to one-way reflective strips; it is suitable for mountainous areas, remote road sections and other scenarios without fixed lighting, allowing passing vehicles and rescue personnel to find the location of emergency personnel from multiple angles, reducing the risk of collision, and providing all-round safety protection for nighttime emergency calls.

[0053] Battery 7 is a lithium battery, and the battery life is no less than 12 hours.

[0054] The advantages of the above setup are: lithium batteries are small in size, light in weight, and have high energy density. They can be embedded in the heel of the shoe without taking up too much space or adding extra weight to the shoe, which meets the requirements of lightweight design; the battery life of ≥12 hours can meet the needs of overnight outpatient visits without frequent charging, avoiding the failure of the warning light due to depletion of power during emergency treatment; lithium batteries have a long charge and discharge cycle life and strong stability, and can adapt to temperature and vibration changes in harsh environments, ensuring the continuous reliability of the warning function.

[0055] Warning light 9 is an LED warning light, which has two working modes: constant light and flashing light.

[0056] The advantages of the above settings are: the LED warning light has low energy consumption, high brightness, and long service life, and can maintain stable illumination when the battery is low, and the battery life can be further extended when paired with a lithium battery; the two working modes can adapt to different scenario needs, the constant light mode is suitable for basic warnings during routine nighttime emergency calls, and the flashing mode is suitable for emergencies or unlit road sections, which improves visibility through dynamic light and quickly attracts the attention of the surroundings; the mode switching operation is convenient and can be controlled with one button on the side of the shoe, which is in line with the working habits of emergency personnel to respond quickly.

[0057] Working principle

[0058] These multi-functional, rainproof, and slip-resistant emergency shoes, designed for harsh pre-hospital emergency environments, achieve four core functions through the coordinated operation of various structures: slip resistance and shock absorption, rain and water resistance, nighttime warning, and emergency adaptability. They are suitable for various harsh emergency response scenarios. Their specific working principle is as follows:

[0059] I. Working Principle of Anti-slip and Shock Absorption Function

[0060] The core of this function relies on the multi-layered structure design of the sole 1, achieving both anti-slip and shock absorption effects through the synergy of material properties and structure. First, the outsole 101 is made of highly wear-resistant rubber material, with its composite anti-slip pattern forming the core anti-slip structure: the deep-tooth anti-slip pattern 102 distributed throughout the sole has a depth of no less than 8mm. When walking in mountainous or muddy areas, the pattern can actively embed itself into the gaps between gravel and muddy soil, increasing the mechanical gripping force between the sole and the ground; the biomimetic gecko claw pattern 103 concentrated in the forefoot and heel impact areas increases the friction with wet and slippery tiles and ice surfaces through its biomimetic concave-convex structure. Together, these two features ensure that the dynamic anti-slip coefficient of the sole is no less than 0.85, effectively preventing slippage. Meanwhile, the puncture-resistant steel plate layer 104 at the top of the outsole 101 can block sharp objects from penetrating, and the EVA shock-absorbing layer 105 above buffers the impact of bumpy roads through a honeycomb structure. The elastic rebound pad 106 embedded in the heel can quickly absorb the impact of running and sudden stopping and rebound, reducing foot fatigue and adapting to the high-frequency dynamic movements of emergency personnel.

[0061] II. Working Principle of Rainproof and Waterproof Function

[0062] The shoe features a fully enclosed waterproof system constructed from the upper (2), upper (3), and matching sealing structure, achieving an IPX6 waterproof rating. The upper (2) and upper (3) are made of a single piece of waterproof, breathable, highly elastic, and abrasion-resistant fabric, with a breathable mesh lining on the inner side that allows for air circulation while preventing rainwater penetration and avoiding stuffiness. The upper (2) is seamlessly connected to the sole (1) using a heat-sealing process, eliminating the risk of water seepage at the seams. The double-layered waterproof edging (4) at the opening of the upper (3) conforms to the ankle curve, and the Velcro tightening strap (5) on the outside further tightens the opening, forming a double seal to prevent mud and water from seeping in. The integrated tongue seamlessly connects to the upper (2), preventing rainwater from entering through gaps in the tongue. This multi-structure synergy provides comprehensive waterproofing even in heavy rain and flooded conditions.

[0063] III. Working Principle of Nighttime Alarm Function

[0064] The dual structure of reflective strips and LED warning lights enhances nighttime visibility. The 360° reflective strips 6 on both sides and the back of the shoe upper 3 are made of high-brightness reflective material, reflecting light from all directions when illuminated by car headlights or flashlights at night, creating a prominent visual indication and expanding the warning range. Meanwhile, the battery 7 embedded in the heel of the shoe upper 2 provides continuous power to the LED warning light 9. A control switch 8 on the outside of the shoe upper allows for one-button switching between constant and flashing modes. The battery 7 has a battery life of at least 12 hours, meeting the needs of extended outreach in unlit areas at night. This dual warning structure significantly reduces the risk of collisions.

[0065] IV. Working Principle of Emergency Adaptation Function

[0066] Designed with emergency medical personnel's work habits in mind, the shoe balances practicality and flexibility. The upper (2) and the upper (3) are made of waterproof, breathable, highly elastic, and abrasion-resistant fabric with a stretch rate of ≥150%, easily adapting to protective boot covers without affecting the combination of protective gear and improving work efficiency. Meanwhile, by optimizing the materials and dimensions of each structure, the overall weight of the shoe is kept below 300 grams. While integrating multiple functions, this ensures that emergency personnel's rapid running, climbing, and other movements are not hindered by weight, meeting the urgent needs of pre-hospital emergency care.
