Description

Technical Field

[0001] This utility model belongs to the field of outdoor equipment technology, specifically relating to a backpack that prevents hypothermia. Background Technology

[0002] In recent years, people's enthusiasm for outdoor sports has been growing. Driven by both the demand for outdoor fitness and entertainment and the stimulus of policies for the development of outdoor sports, outdoor sports have become an important focus of my country's sports development in the new era.

[0003] However, the risks of some high-risk outdoor sports are becoming increasingly apparent, and outdoor adventure activities still carry risks, especially hypothermia accidents, which occur year after year with serious consequences. Hypothermia is one of the common dangers of outdoor activities in winter. When the body loses more heat than it gains, the core temperature of the body drops, leading to a series of symptoms such as chills, disorientation, and cardiopulmonary failure, and even death. Even in summer, there are temperature differences between day and night. Marathon running increases sweating and humidity, and combined with stronger winds, rapid heat loss and hypothermia are very likely, not to mention in severe or extreme weather. Accidents caused by hypothermia are frequent in adventure activities.

[0004] Currently, most outdoor cold-weather gear on the market is passive insulation, such as down jackets and fleece jackets. However, these garments are bulky, inconvenient to pack, and add to the burden of travel, leading many users to avoid carrying them due to the inconvenience. Utility Model Content

[0005] The purpose of this invention is to solve the aforementioned technical problems in the existing technology and provide a hypothermia prevention backpack that integrates a backpack and vest, breaking the traditional mode of requiring separate carrying and donning of thermal insulation equipment. Users do not need to predict the weather in advance or carry extra heavy clothing. When encountering severe weather or experiencing early signs of hypothermia, they can immediately inflate the vest cavity through the valve to quickly build an insulation layer, greatly improving the immediacy and convenience of protection.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A hypothermia prevention backpack includes a backpack and a vest, which are connected by stitching. Its key feature is that the vest has an internal cavity and an air valve that allows air to be inflated into the cavity.

[0008] Furthermore, the vest includes a methyl ester layer, which comprises a fabric layer and a cotton layer, with the fabric layer and cotton layer fixedly connected, and a cavity formed between the methyl ester layers.

[0009] Furthermore, an aluminum film layer is fixed to the cotton layer.

[0010] Furthermore, the methyl methacrylate layer has pressing points, where the fabric layer and cotton layer are bonded together.

[0011] Furthermore, both the fabric layer and the cotton layer are provided with through holes, and the air valve includes a valve seat and a valve cover. The valve seat passes through the through hole and is fixed to the methyl methacrylate layer by hot melt adhesive.

[0012] Furthermore, the backpack includes a backpack base layer, one side of which has a waterproof layer, and the other side of which has a coating.

[0013] Furthermore, the backpack's base layer is made of Oxford cloth, the waterproof layer is a thermoplastic polyurethane elastic layer, and the coating is a polyurethane coating.

[0014] Furthermore, the backpack's base layer is fixed with a support plate.

[0015] Furthermore, the backpack base layer is equipped with a connecting strap, which is fixed to the backpack base layer by sewing. A set distance is maintained between two adjacent sewing points, so that a connecting hole is formed between the connecting strap and the backpack.

[0016] Furthermore, reflective strips are fixed to the base layer of the backpack.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This invention integrates a backpack and vest, breaking away from the traditional model where thermal gear needs to be carried and put on / taken off separately. Users no longer need to anticipate the weather or carry extra heavy clothing. In case of severe weather or early signs of hypothermia, they can immediately inflate the vest's cavity via a valve to quickly build an insulating layer, greatly improving the immediacy and convenience of protection.

[0033] like Figures 1 to 9 As shown, this utility model provides a hypothermia prevention backpack, which includes a backpack 2 and a vest 1. The vest 1 and the backpack 2 are connected by stitching, integrating the backpack 2 and the vest 1 into one unit, breaking the traditional model of separating the backpack and warm clothing, so that users do not need to carry extra heavy clothing.

[0034] Vest 1 includes a metal layer, which comprises a fabric layer 13 and a cotton layer 14. A hot melt adhesive film is placed on the cotton layer 14, and then the aluminum film layer and the cotton layer 14 are stacked together. The hot melt adhesive film is melted by high temperature and high pressure, penetrating into the fibers of the cotton layer 14 and the aluminum film layer substrate. After pressing and cooling, the melted adhesive film re-solidifies, which can firmly bond the aluminum film layer and the cotton layer 14 together.

[0035] This invention uses a heated mold, which, under specific pressure and temperature, acts on the material, causing the hot melt adhesive film between the fabric layer 13 and the cotton layer 14 to melt. After cooling, a strong bond forms at the pressure point, creating a pressing point 11, while the areas between the methylene layers that are not bonded remain separated. During inflation, the gas expands these areas, forming cavities. This process does not damage the aluminum mold layer, ensuring optimal insulation and airtightness, and avoids the risk of air leakage due to broken threads or torn pinholes.

[0036] Vest 1 is equipped with an air valve 12, which includes a valve seat 121 and a valve cover 122. Both the fabric layer 13 and the cotton layer 14 have through holes 15. The valve seat 121 passes through the through holes 15 and is fixed to the vest body layer using a ring-shaped hot melt adhesive. The valve cover 122 is opened from the valve seat 121, allowing air to be injected into the cavity. After inflation, the cavity forms a stable air insulation layer, which effectively prevents heat loss from the body to the external low-temperature environment. The air valve 12 is prior art, and its specific structure will not be described further in this invention.

[0037] Backpack 2 includes a backpack base layer 21, which is made of Oxford cloth, specifically 600D Oxford cloth, offering excellent abrasion resistance. The outer side of the backpack base layer 21 has a waterproof layer 26, a thermoplastic polyurethane elastic layer, also known as a TPU composite layer. This layer is bonded to the Oxford cloth substrate under high temperature and pressure. The TPU composite layer is completely dense and non-porous, forming a physical barrier that completely blocks the passage of liquid water. This means that backpack 2 can keep its contents dry even when submerged in rain or for a short time. Furthermore, the TPU composite layer has a smooth, seamless surface, making it difficult for stains to adhere. Even if it gets dirty with mud or oil, it can be easily cleaned with a damp cloth. The inner side of the backpack base layer 21 has a coating 27, a polyurethane coating, also known as a PU coating. This coating is applied to the other side of the Oxford cloth substrate through processes such as scraping or spraying, and then cured to form a coating 27 covering the fiber surface. After the PU coating cures, it's like wrapping each yarn and fiber with a layer of "glue," making them bond together more tightly. This increases the fabric's stiffness and tear resistance, making the bag more upright, less prone to collapsing, and more durable.

[0038] The backpack base 21 has a support plate 25, which can be a PE board. This support plate, 1mm thick, is a structural support component within the backpack 2 and has a glossy finish on both sides. A foam layer 212, made of EVA and approximately 8mm thick, is glued to the surface of the PE board. The foam layer 212 is divided into five sections. The top four sections have gaps on the sides and top and bottom, while the bottom section is a single piece, providing continuous, complete, and strong support for the waist (lumbar spine). A pointed tip 2121 is located in the middle of the bottom foam layer 212, positioned between the left and right foam layers 212, with a gap between them. This positions the foam layer 212 precisely along the back of the user, and the gaps between the foam layers provide room for bending and twisting of the back during activities such as hiking and climbing. Next, fix the PE board and the inner lining 29 with glue, and then sew the inner lining 29 to the base layer 21 of the backpack.

[0039] The backpack base 21 is equipped with connecting straps 22, which are designed in yellow to make them more conspicuous and easily spotted by the user or companions. The connecting straps 22 and the backpack base 21 are fixed together by stitching, with a set distance between adjacent stitching points, creating multiple connecting holes 23 between the connecting straps 22 and the backpack 2. These connecting holes 23 can serve as quick, temporary attachment points for hanging small items such as ice axes, trekking poles, headlamps, and gloves, or for secondary securing with ropes, greatly expanding the flexibility and convenience of external attachments to the backpack 2. Furthermore, when the connecting straps 22 are subjected to external tension (such as when suspending heavy objects), the force is more evenly distributed across a larger area of ​​the backpack base 21 through the various stitching points, preventing excessive stress concentration on any single seam. This invention can have four connecting straps 22, with two straps having a length equivalent to the entire height of the backpack 2, and the other two straps having a length equivalent to half the height of the entire backpack 2.

[0040] Side pockets 24 are sewn onto the sides of the backpack base 21, which are used to store survival tools.

[0041] Based on the technical solutions of the above embodiments, another embodiment of this utility model is designed, such as... Figure 10 As shown, it adds emergency safety extension functions to the basic functions of backpack 2. Specifically:

[0042] (1) The backpack base layer 21 is fixed with reflective strips 28 by sewing. In environments with insufficient light, such as at night, dusk, dawn or rainy / foggy weather, when a light source (such as a vehicle headlight or flashlight) shines on the reflective strips 28, the user of the backpack 2 becomes an extremely bright and eye-catching light source.

[0043] (2) A compartment 210 is designed at the top cover of the backpack 2. The compartment 210 is made of transparent waterproof material (such as transparent TPU) as a window. The LED light module 211 is fixed inside the compartment 210 by Velcro. It is independent and emits light directly through the window of the compartment 210.

[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
