Abstract
Description
Technical Field
[0001] This application relates to the field of fire boot technology, and in particular to a protective boot for firefighters in rescue operations. Background Technology
[0002] The scenarios faced by firefighters and rescue workers today are complex and dangerous, including urban fires involving high-rise buildings and electrical hazards, forest fires involving high temperatures and rugged terrain, and chemical accidents involving chemical corrosion and the threat of flammable and explosive materials. In these high-risk environments, the performance of fire boots worn by firefighters and rescue workers is directly related to their safety and the effectiveness of rescue efforts.
[0003] Traditional firefighting rubber boots are hot, heavy, and irritate the skin. They also rarely take into account the natural movement needs of firefighters' feet during missions. The stiff boots restrict the flexible rotation of the ankle joint. When firefighters climb or cross obstacles, they need to expend more effort to overcome the constriction of the boots. This not only reduces the efficiency of their actions but also easily leads to muscle fatigue. Especially in emergency situations that require rapid response, the inflexibility of the boots may affect the timeliness and accuracy of rescue operations.
[0004] With the increasing specialization of firefighting and rescue work, the requirements for the comfort of fire boots are becoming higher and higher. Developing a fire boot that can provide comprehensive protection and ensure a comfortable wearing experience during long-term operations has become an urgent need to improve the quality of rescue work and protect the physical and mental health of rescue personnel. Utility Model Content
[0005] To improve the comfort of firefighters wearing fire boots, this application provides a firefighter rescue and relief protective boot.
[0006] This application provides a firefighter rescue protective boot, which adopts the following technical solution:
[0007] A firefighter rescue protective boot includes an integrally formed sole, toe, upper, heel, and shaft. The inner surfaces of the toe, upper, and shaft are all fitted with waterproof sock liner. The top of the shaft is detachably fitted with a protective sleeve to prevent fine particles from entering the boot.
[0008] By adopting the above technical solution, and utilizing the waterproof sock liner on the inner surface of the toe, upper, and shaft of the boot, it is ensured that firefighters' feet will not get wet when working in water-related environments. The waterproof sock liner also has high breathability, chemical protection, and resistance to blood transmission and viral pathogens. At the same time, the protective sleeve prevents small particles such as sand and glass shards from entering the boot, avoiding friction and injury to the feet.
[0009] Preferably, the two ends of the protective sleeve are attached with Velcro, and the outer wall of the protective sleeve is attached to the inner wall of the boot shaft with Velcro.
[0010] By adopting the above technical solution, the two ends of the protective sleeve are attached with Velcro, allowing firefighters to flexibly adjust the size of the protective sleeve according to the thickness of their calves, thus adapting it to the different calf sizes of firefighters; at the same time, the outer wall of the protective sleeve is attached to the inner wall of the boot with Velcro, making it easy for firefighters to quickly assemble or remove the protective sleeve for cleaning according to actual needs.
[0011] Preferably, the protective sleeve is provided with an elastic tightening rope inside to facilitate firefighters to tighten the protective sleeve.
[0012] By adopting the above technical solution and utilizing the elastic tightening rope, firefighters are allowed to adjust the tightness of the protective sleeve according to their own needs, thereby preventing small particles from entering from the top of the boot and avoiding injury caused by particles rubbing against the feet.
[0013] Preferably, the boot sole includes a rubber outsole, an energy-absorbing PU midsole, and a puncture-resistant soft sole, wherein the energy-absorbing PU midsole is disposed between the rubber outsole and the puncture-resistant soft sole.
[0014] By adopting the above technical solutions, the rubber outsole has good wear resistance and anti-slip properties, and can provide stable support and walking safety in various complex ground environments; the energy-absorbing PU midsole plays a key role in cushioning and absorbing energy, reducing shock damage to the feet and body, and alleviating fatigue caused by standing and moving for a long time; the puncture-resistant soft sole can effectively prevent sharp objects from piercing the sole of the boot, protecting the firefighters' feet from punctures.
[0015] Preferably, the inner surface of the boot shaft opening is covered with a comfortable and breathable mesh fabric.
[0016] By adopting the above technical solution, and by attaching a comfortable and breathable mesh fabric to the inner surface of the boot opening, the comfortable and breathable mesh fabric has good breathability, which can help the sweat on the feet evaporate quickly and keep the feet dry, and can also effectively improve the comfort of firefighters when wearing it.
[0017] Preferably, the bottom of the rubber outsole is provided with a pattern to increase friction with the ground.
[0018] By adopting the above technical solution and utilizing the base pattern, firefighters can form more contact points and friction with the ground, making them more stable when walking, less prone to slipping, and helping them to reach the rescue location or carry out their mission quickly and safely.
[0019] Preferably, the base is provided with anti-slip teeth to increase grip, the surface of the anti-slip teeth is provided with oil-proof grooves, and the sides of the anti-slip teeth are provided with self-cleaning side slopes.
[0020] By adopting the above technical solution, the anti-slip teeth can be embedded in ground gaps or better fit with irregular ground surfaces, and the oil-proof groove can store or discharge oil, reducing the area of the oil film on the contact surface, thereby maintaining friction and improving the safety and stability of firefighters' movements in complex terrain. At the same time, the self-cleaning side slope and the oil-proof groove form a golden angle, generating vortex airflow during the gait cycle, thereby drawing residual oil into the oil-proof groove. During the heel lift-off phase, the oil is thrown out along the self-cleaning side slope by inertia, thus achieving the self-cleaning function.
[0021] Preferably, the bottom of the rubber outsole is provided with zigzag grooves to increase walking flexibility.
[0022] By adopting the above technical solution and utilizing the setting of the zigzag groove, the design of the zigzag groove changes the force distribution and friction when the rubber outsole contacts the ground. When firefighters walk or stand, the zigzag groove can deform to a certain extent according to the ground conditions, better conform to the ground contour, increase the contact area between the sole and the ground, thereby increasing grip and walking flexibility.
[0023] Preferably, the bottom of the rubber outsole is provided with an anti-slip step surface to prevent firefighters from slipping.
[0024] By adopting the above technical solution and utilizing the anti-slip stepped surface, the friction between the sole of the shoe and the ground is increased, ensuring the stability of firefighters' steps, reducing the risk of slipping, and ensuring their safety during rescue missions.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. By using waterproof socks on the inner surface of the toe, upper, and shaft, firefighters' feet are kept dry when working in water-filled environments. The waterproof socks are also highly breathable, chemically protective, and resistant to bloodborne and viral pathogens. At the same time, the protective sleeves prevent small particles such as sand and glass shards from entering the boots, avoiding friction and injury to the feet.
[0027] 2. The rubber outsole has good wear resistance and slip resistance, providing stable support and walking safety in various complex ground environments; the energy-absorbing PU midsole plays a key role in cushioning and absorbing energy, reducing shock damage to the feet and body, and alleviating fatigue caused by prolonged standing and movement; the puncture-resistant soft sole can effectively prevent sharp objects from piercing the sole of the boot, protecting the firefighter's feet from punctures.
[0028] 3. By attaching a comfortable and breathable mesh fabric to the inner surface of the boot opening, the comfortable and breathable mesh fabric has good breathability, which can help the sweat on the feet evaporate quickly and keep the feet dry, and can also effectively improve the comfort of firefighters when wearing it.

Detailed Implementation
[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.
[0034] This application discloses a protective boot for firefighters during rescue operations.
[0035] Example 1:
[0036] Reference Figure 1 A firefighter rescue protective boot includes an integrally designed sole 1, toe 2, upper 3, heel 4, and boot shaft 5. The heel 4 is provided with an ankle joint flexing layer 41, which improves the flexibility of the boot at the ankle, enabling firefighters to make more timely and accurate responses in emergency situations.
[0037] Reference Figure 1 The toe cap 2 is made of TPU material, the upper 3 and heel 4 are made of high-quality waterproof and flame-retardant leather, and the ankle joint flex layer 41 and boot shaft 5 are made of waterproof and flame-retardant soft leather. It can not only effectively block flames and high temperatures, but also has waterproof function to prevent water stains and chemical liquid penetration, protect the safety of firefighters' feet, and fully meet the protection needs of complex rescue environments.
[0038] Reference Figure 1 The sole 1 is a three-layer composite structure. From bottom to top, the sole 1 includes a rubber outsole 11, an energy-absorbing PU midsole 12, and a puncture-resistant soft sole 13. The energy-absorbing PU midsole 12 is located between the rubber outsole 11 and the puncture-resistant soft sole 13. The rubber outsole 11 is made of high wear-resistant rubber and has excellent anti-slip, electrical insulation and high temperature resistance properties.
[0039] Reference Figure 1 The rubber outsole 11 is made of a material that can withstand long-term friction and wear, extending the service life of the fire boots. The energy-absorbing PU midsole 12 plays a key role in cushioning and absorbing energy. When firefighters walk or jump, the impact force of the ground is transmitted through the rubber outsole 11 to the energy-absorbing PU midsole 12. The energy-absorbing PU midsole 12 can effectively absorb and disperse these impact forces, reducing shock damage to the feet and body, and alleviating fatigue caused by standing and moving for a long time. The puncture-resistant soft sole 13 can effectively prevent sharp objects from puncturing the boot sole 1, protecting the firefighter's feet from punctures. For example, dangerous items such as glass shards and sharp metal objects that may be present at the fire scene. The puncture-resistant soft sole 13 provides a reliable protective barrier for firefighters, ensuring their safety in complex ground environments.
[0040] Reference Figure 2 The bottom of the rubber outsole 11 is provided with multiple sole patterns 111, anti-slip lugs 112, oil-proof grooves 113, self-cleaning side slopes 114, and zigzag grooves 115 to enhance grip. The sole patterns 111 have a special shape and texture design, which makes firefighters form more contact points and friction with the ground, making firefighters more stable when walking. The anti-slip lugs 112 are set on the surface of the sole patterns 111. When the ground is relatively wet or has a special texture, the anti-slip lugs 112 can be embedded into the ground gaps or better fit the irregular surface of the ground, thereby effectively preventing firefighter boots from slipping.
[0041] Reference Figure 2 The oil-proof groove 113 is set on the surface of the anti-slip tooth ear 112. When the anti-slip tooth ear 112 comes into contact with the oily ground, on the one hand, the oil-proof groove 113 can store or discharge oil, reducing the area of the oil film on the contact surface, thereby maintaining friction; on the other hand, the oil-proof groove 113 can guide the flow of oil and prevent it from accumulating on the surface of the anti-slip tooth ear 112, thereby avoiding slipping. The self-cleaning side slope 114 is set on the side of the anti-slip tooth ear 112, and the self-cleaning side slope 114 and the oil-proof groove 113 form a golden angle, generating vortex airflow in the gait cycle. During the forefoot push-off phase when walking, a Bernoulli effect negative pressure zone is generated inside the oil-proof groove 113, thereby drawing residual oil into the oil-proof groove 113; during the heel lift-off phase, the oil is thrown out along the self-cleaning side slope 114 by inertial force, thereby achieving the self-cleaning function.
[0042] Reference Figure 2 The design of the zigzag groove 115 changes the force distribution and friction when the rubber outsole 11 contacts the ground. When firefighters walk or stand, the zigzag groove 115 can deform to a certain extent according to the ground conditions, better conforming to the ground contour, thereby increasing grip and walking flexibility. In addition, the zigzag groove 115 can also guide water or other liquids out of the sole, avoiding slippage caused by water accumulation on the sole. It is particularly suitable for fire rescue sites that are wet, muddy, or prone to water accumulation, improving the safety and stability of firefighters' actions on complex terrain, and enabling them to cope with various rescue environments more freely.
[0043] Reference Figure 2 The rubber outsole 11 has an anti-slip stepped surface 116 near the heel 4. When firefighters walk, the different steps of the anti-slip stepped surface 116 can generate multi-dimensional friction and resistance with the ground. Even on relatively smooth or inclined surfaces, it can effectively prevent the feet from sliding forward or backward, providing stable support for firefighters. In scenarios such as going up and down stairs or walking on slopes, the anti-slip stepped surface 116 can better adapt to different terrain changes, ensuring the stability of firefighters' steps, reducing the risk of slipping, and ensuring the safety of firefighters during rescue missions.
[0044] Reference Figure 1 The inner surface of the toe (2), upper (3), and shaft (5) is fitted with a waterproof sock liner. The waterproof sock liner uses GORE-TEXCROSSTECH® waterproof and breathable fabric, which on the one hand achieves excellent waterproof function, ensuring that firefighters' feet will not get wet when working in water-related environments, avoiding problems such as cold, frostbite, and bacterial growth caused by dampness. On the other hand, the waterproof sock liner also has high breathability, chemical protection, and resistance to blood transmission and viral pathogens.
[0045] Reference Figure 1 The toe box 2 features a synthetic toe cap positioned between the TPU material and the waterproof sock liner. This synthetic toe cap can withstand external pressure, providing impact resistance and maintaining the stability of the toe shape. It also prevents foot discomfort or restricted movement caused by compression, while enhancing the structural strength of the front of the boot and improving overall protective performance.
[0046] Reference Figure 1 The boot shaft 5 is equipped with foam, which is placed between the waterproof sock and the high-quality waterproof and flame-retardant leather, and between the waterproof sock and the waterproof and flame-retardant soft leather. The foam can improve the comfort of firefighters when wearing it.
[0047] Reference Figure 1The inner surface of the boot shaft 5 is lined with a comfortable and breathable mesh fabric. The comfortable and breathable mesh fabric adopts an air convection channel design, which can help the sweat on the feet evaporate quickly and effectively promote the expulsion of sweat. It also helps to avoid skin abrasion or blisters caused by prolonged wear, thus improving the wearer's comfort. On the other hand, the waterproof sock liner, together with the comfortable and breathable mesh fabric, enhances the integrity and stability of the boot's interior.
[0048] Reference Figure 1 The boot shaft 5 is equipped with a shoelace rotating buckle 51 that allows firefighters to quickly adjust the tightness of their shoelaces. This allows firefighters to quickly tighten or loosen the shoelaces according to their foot condition, ensuring a proper fit and preventing the shoelaces from coming loose or coming off during rescue operations. This reduces the risk of tripping and avoids the risk of getting tangled or snagged on tree branches, making it especially suitable for high-intensity work scenarios such as climbing and running. At the same time, the shoelace rotating buckle 51 is easy to operate, saves dressing time, and allows firefighters to quickly get ready when responding to an emergency, improving response efficiency.
[0049] Reference Figure 1 The boot shaft 5 is equipped with reflective strips 52. In low-light rescue environments, such as nighttime fire scenes or places with heavy smoke, the reflective strips 52 can reflect the surrounding light back, making firefighters easier for other rescuers to spot and improving their visibility in complex environments. This not only helps ensure the safety of firefighters themselves and avoids accidental collisions in chaotic rescue scenes, but also facilitates the identification and dispatch of firefighters by commanders, which is conducive to the orderly conduct of rescue operations.
[0050] The implementation principle of this application embodiment is as follows: When firefighters wear the socks, their feet come into contact with the comfortable and breathable mesh fabric and the waterproof socks in sequence. The waterproof socks and the comfortable and breathable mesh fabric work together to ensure that the feet are dry. At the same time, the energy-absorbing PU midsole 12 absorbs the impact energy generated by the feet through elastic deformation, and the puncture-resistant soft sole 13 provides a reliable protective barrier for firefighters, ensuring their safety in complex ground environments. Meanwhile, the design of the sole pattern 111, anti-slip lugs 112, oil-proof grooves 113, self-cleaning side slopes 114, zigzag grooves 115, and anti-slip stepped surfaces 116 increases the grip of the rubber outsole 11 on the ground, ensuring the stability of the firefighter's steps, reducing the risk of slipping, and ensuring the safety of the firefighter's actions during rescue missions.
[0051] Example 2:
[0052] The difference between Example 2 and Example 1 is that:
[0053] Reference Figure 1 and Figure 3A protective sleeve 53 is detachably installed at the top opening of the boot shaft 5. The protective sleeve 53 effectively prevents small particles such as sand and glass shards from entering the boot, avoids damage caused by particles rubbing against the feet, and improves the comfort of firefighters during operation.
[0054] Reference Figure 1 and Figure 3 The protective sleeve 53 includes, from bottom to top, an adhesive layer 531, a protective layer 532, and a tightening layer 533. The adhesive layer 531 and the protective layer 532 are integrally formed, and the protective layer 532 and the tightening layer 533 are separated by a sewing thread. The inner ring of the adhesive layer 531 of the protective sleeve 53 is provided with a hook and loop fastener, and the outer ring of the adhesive layer 531 of the protective sleeve 53 is provided with a hook and loop fastener, so that the two ends are attached by hook and loop fastener. The inner ring of the boot shaft 5 opening is provided with a hook and loop fastener for attaching the protective sleeve 53. The protective layer 532 and the tightening layer 533 extend out of the opening of the boot shaft 5.
[0055] Reference Figure 1 and Figure 3 When in use, firefighters can flexibly adjust the encirclement size of the protective sleeve 53 according to the thickness of their calves. The outer wall of the protective sleeve 53 is attached to the inner wall of the boot shaft 5 with Velcro, making installation and disassembly convenient. This allows firefighters to quickly assemble the protective sleeve 53 or remove it for cleaning according to actual needs.
[0056] Reference Figure 3 The protective sleeve 53 has an elastic tightening rope 54 inside the tightening layer 533. The protective sleeve 53 has guide ports 534 for avoiding the two ends of the elastic tightening rope 54. The elastic tightening rope 54 passes through the tightening layer 533 and is led out through the guide ports 534. The part of the elastic tightening rope 54 that extends out of the tightening layer 533 is connected to a pig nose spring buckle 55. That is, the two ends of the elastic tightening rope 54 are fixed by the pig nose spring buckle 55.
[0057] Reference Figure 1 and Figure 3 When in use, firefighters press the pig-nose spring buckle 55 and adjust the tension of the elastic tightening rope 54 as needed, thereby pulling and tightening the tightening layer 533 of the protective sleeve 53. This allows firefighters to adjust the tightness of the sleeve opening according to their own needs, preventing foreign objects from entering from the top of the boot 5. The two ends of the elastic tightening rope 54 are locked by the pig-nose spring buckle 55. The operation is simple, and firefighters can quickly complete the adjustment in emergency rescue scenarios.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
