Description

Technical Field

[0001] This invention relates to the field of emergency backpacks and outdoor backpacks, and in particular to a multi-functional emergency backpack. Background Technology

[0002] Existing inflatable backpacks have a wide range of uses; as emergency tools, they can prevent drowning, earthquake injuries, and other injuries.

[0003] For example, Chinese patent CN218551652U discloses a multifunctional earthquake emergency kit, characterized in that the multifunctional earthquake emergency kit includes: a backpack with multiple sets of sponge pads fixedly installed on the backpack; and a protective mechanism disposed inside the backpack, the protective mechanism including a buffer component and a protective plate, the protective plate being able to move when the backpack is subjected to compressive force, and driving the buffer component to move.

[0004] However, backpacks with sealed zippers and formed by thermoforming rather than sewing also have good cushioning and waterproofing capabilities.

[0005] For example, patent CN211747624U discloses an outdoor waterproof backpack with a lifebuoy function and its usage method. The backpack includes: a cylindrical backpack body with an open top, formed by hot-melt adhesive bonding of waterproof fabric; a sealing strip fixed to the opening at the top of the backpack body by stitching; connecting buckles at both ends of the sealing strip; shoulder straps at the back of the backpack body; and handles at the top of the shoulder straps. The shoulder straps and handles are fixed to a sixth fabric block by stitching, and the sixth fabric block is hot-melt adhesive bonded to the back of the backpack body. This invention uses waterproof fabric bonded together by hot-melt adhesive to form a sealed cylindrical structure with an open top, and indirectly installs other components onto the backpack body by hot-melt adhesive bonding of fabric blocks. This makes the backpack body not only highly waterproof, but its excellent airtightness allows it to function as a lifebuoy after drowning, buying precious rescue time for the drowning victim.

[0006] The problem with existing technology is that, although existing emergency kits have cushioning and buoyancy functions, when used in water, a major reason why people cannot be rescued while waiting for rescue is that they are swept away by the current. This makes it difficult for rescuers to quickly find the people waiting for rescue, greatly increasing the rescue time and potentially leading to rescue failure. This is especially true when hiking or canyoning outdoors. If someone is swept downstream from the accident site by the current, they are difficult to find and are likely to be seriously injured in the process.

[0007] Therefore, existing technologies need to be improved. Summary of the Invention

[0008] To solve the above-mentioned technical problems, the purpose of this invention is to provide a multi-functional backpack for emergency use, which, when used in water, can not only prevent drowning but also prevent the user from being swept away.

[0009] The technical solution adopted by this invention to solve the problem is: an emergency multi-functional backpack, comprising:

[0010] The main body includes a front cover and a rear cover, which are sealed together by a zipper. Both the front and rear covers are integrally formed by hot pressing. The rear cover has two shoulder straps with stitched sections. It also includes an outer shell, the front cover of which is connected to the front end. The outer shell has a claw, and a magnet or spring is provided between the claw and the outer shell. When the front cover is opened, the claw can pop out the outer shell. The rear end of the outer shell has a winding shell with a connecting rope wound inside. The outer end of the connecting rope is sewn to the stitched sections.

[0011] As a further improvement to the above technical solution, one side of the front cover is hinged to the outer shell, and a connecting piece is welded to the other side of the front cover. One end of the connecting piece is welded to the outer wall of the outer shell. A spring is installed on the outer shell, and the free end of the spring has a spike facing the connecting piece. The connecting piece is made of tempered glass, and the spring is made of steel. The diameter of the front cover is larger than the diameter of the outer shell, and the vertical projection of the front cover completely covers the connecting piece, the spring, and the outer shell. A first connecting part is provided on the shoulder strap, and a second connecting part is provided on the front cover. The second connecting part, the outer end of the connecting rope, and the connecting piece are all located on the same side of the outer shell. The first connecting part and the second connecting part are detachably connected.

[0012] As a further improvement to the above technical solution, the outer shell includes a rear body with a front end opening and a front body with both ends opening. The front end of the rear body is threadedly connected to the rear end of the front body. The front edge of the front body is provided with an inwardly extending front retaining ring, and the outer wall of the rear body is provided with an outwardly protruding rear retaining ring. The number of outer shells is at least two, and the two outer shells are nested inside and outside each other. The rear retaining ring of one outer shell abuts against the front retaining ring of its adjacent outer shell.

[0013] As a further improvement to the above technical solution, the claw includes a mounting base, which is sleeved inside the housing. The outer wall of the mounting base is provided with a flange, which abuts against the front retaining ring on the housing.

[0014] As a further improvement to the above technical solution, the claw includes several hooks, the mounting base is provided with a limiting ring, the limiting ring is provided with a hinge seat, the hooks are rotatably connected to the hinge seat and a torsion spring is provided between the hooks and the hinge seat, the torsion spring pushes the hooks toward the limiting ring, the limiting ring is located outside the hinge seat; the front end of the hook is provided with an inwardly protruding, sharp-ended fixing part, the outer wall of the hook is rotatably connected with a secondary hook and a torsion spring is provided between the hooks, the rear end of the secondary hook can rotate within ° away from the hook under the action of the torsion spring, the hook is provided with a relief groove, and the secondary hook can be folded into the relief groove.

[0015] As a further improvement to the above technical solution, a reinforcing strap is also included. The two ends of the reinforcing strap are respectively fixedly connected to the two back straps. The reinforcing strap includes a first strap body with a male buckle and a second strap body with a female buckle. The male buckle and the female buckle are detachably connected.

[0016] As a further improvement to the above technical solution, the inner wall of the main body is provided with Velcro.

[0017] As a further improvement to the above technical solution, the shoulder strap is provided with a storage bag, and the storage bag contains a cutting tool. The cutting tool includes a blade shell, one end of which is fixedly mounted with a metal or stone hammer head. A blade is installed inside the blade shell, and a pushing block is connected to the blade. The pushing block is slidably connected to the blade shell, and when the pushing block is pushed, it can cause the blade to extend out of the blade shell.

[0018] As a further improvement to the above technical solution, the outer shell is provided with anti-slip texture.

[0019] The beneficial effects of this invention are:

[0020] 1. The front cover and the rear cover are sealed together by a sealing zipper. Both the front cover and the rear cover are integrally formed by hot pressing. This makes the overall body highly airtight and can be used to buffer the impact of falling objects, protect the human body, and play a certain role in earthquakes.

[0021] 2. The main body can accommodate first aid supplies, such as medicines, gauze, flashlights, etc., to better serve an emergency purpose;

[0022] 3. Due to its airtight structure, it can be used in water, such as to help people float when drowning or swept away by floodwaters.

[0023] 4. The outer shell is attached to the shoulder strap. When caught in the water, the outer shell can be easily retrieved, the front cover can be opened, and the claws can be exposed. The claws can be used to anchor to fixed objects such as trees, stream rocks, etc., to prevent being swept away by the water and to facilitate discovery and rescue by rescuers. If a connecting rope is set, the claws can be thrown to a greater distance. Attached Figure Description

[0035] Reference Figures 1 to 6 An emergency multi-functional backpack, comprising:

[0036] The main body 1 includes a front cover 23 and a rear cover 12, which are sealed together by a zipper. Both the front cover 23 and the rear cover 12 are integrally formed by hot pressing. The rear cover 12 is connected to two shoulder straps 13, which are provided with a sewn part 131. The main body 1 also includes an outer shell 2, which is connected to the front cover 23 at its front end. The outer shell 2 is provided with a claw 24, and a magnet 3 or a spring is provided between the claw 24 and the outer shell 2. When the front cover 23 is opened, the claw 24 can pop out the outer shell 2. The rear end of the outer shell 2 is provided with a winding shell 4, in which a connecting rope 5 is wound. The outer end of the connecting rope 5 is sewn to the sewn part 131.

[0037] The hot-pressing integrated molding described in this invention refers to the same molding method as "forming a cylindrical shape by hot-pressing waterproof fabric with hot melt adhesive" in the background art.

[0038] In this invention, the claw 24 is concealed within the outer shell 2, which is connected to the shoulder strap 13. The outer shell 2 and claw 24 together provide portability, making this emergency multi-functional backpack suitable for outdoor hiking, stream tracing, and other similar activities. In emergencies, such as rising stream water or a fall while climbing, the user can remove the outer shell 2 from the shoulder strap 13, open the front cover 23, and the claw 24 will pop out of the shell under the action of a magnet or spring. Specifically, repulsive magnets can be provided on both the outer shell 2 and the claw 24, or a compressed spring can be provided between the outer shell 2 and the claw 24. The claw 24 can be used to anchor nearby rocks, trees, etc., to prevent being swept away by rapid currents or to prevent further falls during a fall while climbing, allowing the user to wait for rescue and making it easier for rescuers to find the user. If the user does not throw the outer shell 2 far enough, the claw 24 and the outer shell 2 can also fall to the bottom of the stream and anchor to an external fixed object under their own weight. Once the water flow weakens, if the connecting rope 5 initially extends too far and the user is too far from the fixed object of the external device, the user can pull the connecting rope to move their body closer to the fixed object of the external device and avoid continuing to float as much as possible.

[0039] In addition, the main body 1 itself has excellent airtightness, which can help it float and resist impacts, thus preventing drowning and injury from falling objects. Since the main body 1 can hold supplies, users can stay on rocks or trees while waiting for rescue, and the food, water, and medicine in the main body 1 can be used.

[0040] In a preferred embodiment, one side of the front cover 23 is hinged to the outer shell 2, and a connecting piece 6 is welded to the other side of the front cover 23. One end of the connecting piece 6 is welded to the outer wall of the outer shell 2. A spring piece 7 is installed on the outer shell 2, and the free end of the spring piece 7 has a spike facing the connecting piece 6. The connecting piece 6 is made of tempered glass, and the spring piece 7 is made of steel. The diameter of the front cover 23 is larger than the diameter of the outer shell 2, and the vertical projection of the front cover 23 completely covers the connecting piece 6, the spring piece 7, and the outer shell 2. The shoulder strap 13 has a first connecting part 14, and the front cover 23 has a second connecting part 8. The second connecting part 8, the outer end of the connecting rope 5, and the connecting piece 6 are all located on the same side of the outer shell 2. The first connecting part 14 and the second connecting part 8 are detachably connected. The first connecting part 14 and the second connecting part 8 can be made of Velcro, buckles, etc. In an emergency, the user can reach out and pull the end of the outer casing 2 near the front cover 23 outwards. The first connecting part 14 will separate from the second connecting part 8, and the spring clip 7 will be pinched. The spikes on the spring clip 7 will break the connecting piece 6, and the claw 24 will automatically pop outwards from the front cover 23. The claw 24 can then be used to anchor the peripheral device to fixed objects, such as rocks or trees. The user can throw the outer casing 2, but if the fixed object is not far away, it is not necessary to throw it. Because tempered glass is used as the connecting piece 6, the connecting piece 6 must be broken to use the claw 24. After each use, the connecting piece 6 needs to be replaced and welded to the outer casing 2 and the front cover 23. Therefore, the user should not use it frequently as an everyday item to avoid affecting the function of the claw 24 due to frequent use in emergency situations.

[0041] In a preferred embodiment, the outer shell 2 includes a cap-shaped rear body 21 with an open front end and a tubular front body 22 with open ends. The front end of the rear body 21 is threadedly connected to the rear end of the front body 22. The front edge of the front body 22 is provided with an inwardly extending front retaining ring 221, and the outer wall of the rear body 21 is provided with an outwardly protruding rear retaining ring 211. There are at least two outer shells 2, which are nested inside each other. The rear retaining ring 211 of one outer shell 2 abuts against the front retaining ring 221 of its adjacent outer shell 2. The front body 22 and the rear body 21 are integrally cast or forged. During installation, the smaller outer shell 2 is inserted into the larger outer shell 2's front body 22, and then the larger rear body 21 is installed on the larger outer shell 22. When the claw 24 hooks onto the external fixing object, the two outer shells 2 can be reliably connected and will not separate.

[0042] In a preferred embodiment, the claw 24 includes a mounting base 241, which is fitted inside the housing 2. The outer wall of the mounting base 241 has a flange 242 that abuts against a front retaining ring 221 on the housing 2. The flange 242 and the front retaining ring 221 on the housing 2 ensure a reliable connection between the claw 24 and the housing 2, preventing separation.

[0043] Reference Figure 5 In a preferred embodiment, the claw 24 includes a plurality of hooks 25, the mounting base 241 is provided with a limiting ring 243, the limiting ring 243 is provided with a hinge seat 244, the hooks 25 are rotatably connected to the hinge seat 244 and a torsion spring is provided between the hooks 25 and the hinge seat 244, the torsion spring pushes the hooks 25 toward the limiting ring 243, the limiting ring 243 is located outside the hinge seat 244; the front end of the hook 25 is provided with an inwardly protruding, sharp-ended fixing part 251, the outer wall of the hook 25 is rotatably connected with a secondary hook 252 and a torsion spring is provided between the hook 25 and the secondary hook 252, the rear end of the secondary hook 252 can rotate within 50° away from the hook 25 under the action of the torsion spring, the hook 25 is provided with a relief groove 253, and the secondary hook 252 can be folded into the relief groove 253. A reliable rotating connection can be achieved using methods such as shaft-hole fitting. The torsion spring only serves to open the latch 25 and the locking groove 252. The latch 25 is suitable for anchoring to the fixed object on its inner side, and the secondary latch 252 is suitable for anchoring to the fixed object on its outer side. In emergency situations, the user can easily anchor the fixed object by simply bringing the claw 24 close to it.

[0044] In a preferred embodiment, a reinforcing strap is further included, with both ends of the reinforcing strap being fixedly connected to the two shoulder straps 13. The reinforcing strap includes a first strap body 101 with a male buckle and a second strap body 102 with a female buckle, the male and female buckles being detachably connected. The reinforcing strap is used to connect the two shoulder straps 13 to each other, preventing the shoulder straps 13 from falling off the user.

[0045] In a preferred embodiment, the inner wall of the main body 1 is provided with Velcro 16. A storage bag with an external device fitted with Velcro can be directly attached to the inner wall of the main body 1, facilitating the categorized storage of materials.

[0046] Reference Figure 6In a preferred embodiment, the carrying strap 13 is provided with a storage bag 15, and a cutting tool 9 is provided inside the storage bag 15. The cutting tool 9 includes a blade shell 91, one end of which is fixedly mounted with a metal or stone hammer head 94. A blade 92 is installed inside the blade shell 91, and a pushing block 93 is connected to the blade 92. The pushing block 93 is slidably connected to the blade shell 91, and when the pushing block 93 is pushed, it can cause the blade 92 to extend out of the blade shell 91. When the user has already used the claw 24 to anchor the external device to a fixed object, if the user wants to remove the claw 24 from the fixed object when the connecting rope 5 is extended, but cannot directly reach the claw 24, the cutting tool 9 can be taken out from the storage bag 15 on the carrying strap 13 to cut the connecting rope 5. The hammer is a tool frequently used in outdoor hiking, and fixing it to the cutting tool 9 makes it convenient for the user to use.

[0047] The outer shell 2 is provided with anti-slip texture. This prevents the user from slipping when removing the outer shell from the shoulder strap 13 in an emergency.

[0048] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
