Description

Technical Field

[0001] This utility model relates to the field of carrying bag technology, and specifically to a combination carrying bag. Background Technology

[0002] As a carrier of emergency supplies, the design of an emergency pack directly affects the effectiveness of emergency response. Current emergency packs often employ a single-pack, multi-compartment design, typically including a main pack body and multiple inner compartments. These inner compartments are secured with zippers or fasteners, but they are not removable. Users must open the main pack and rummage through different compartments to find items, a cumbersome process. Another common design uses storage bags to organize items, but this is not secure and items can easily move around inside the pack, causing disarray.

[0003] In emergencies such as earthquakes and fires, users often need to quickly access specific items, such as first-aid kits, fire extinguishers, and escape ropes. Traditionally designed bags require users to memorize the location of items or check them one by one, wasting valuable time. Furthermore, different users or different scenarios require different combinations of items, and bags with fixed compartments cannot be flexibly adjusted, leading to wasted resources or insufficient functionality. For example, in wilderness rescue, medical supplies are in high demand; while in home emergencies, food and water may be more important. Existing carrying bags lack flexibility and cannot adapt to changing scenarios.

[0004] Therefore, there is a need for an improved bag design that enables modular storage of items, allows users to quickly access specific categories of items, and allows for customized configurations as needed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes a combination carrying bag to solve the technical problems of inconvenience in accessing items and inflexible configuration of traditional carrying bags.

[0006] The technical solution of this utility model is implemented as follows: A combination carrying bag, comprising: A mother bag, which has a bag body and an internal storage space; Multiple sub-bags are detachably set within the storage space of the main bag, and each sub-bag is used to classify and store items with different functions; The sub-package is connected to the inside of the mother package through a fixing device, which allows the sub-package to be taken out and put back into the mother package separately.

[0007] Preferably, the fastening device is Velcro, and the front panel of the sub-bag is glued and fixed to the inner front panel of the mother bag by Velcro.

[0008] Preferably, the back of the sub-bag has a hook side with Velcro, and the loop side of the Velcro covers the entire back panel of the mother bag.

[0009] Preferably, the sub-packages include medical emergency kits, emergency food kits, and evacuation supplies kits.

Furthermore, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] See Figure 1 and Figure 4 This utility model provides a combined carrying bag, including a main bag 1 and multiple sub-bags 2. The main bag 1 is made of high-strength nylon fabric, which has waterproof and wear-resistant properties. The bag body of the main bag 1 includes a front panel and a back panel. The back panel is the side closest to the user's back (i.e., the back of the main bag), and the front panel is the side opposite to the back panel, away from the user, and facing the outside world (i.e., the front of the main bag). The inside of the bag body forms a storage space, and the front and back panels of the bag body are connected by a waterproof zipper 6 to prevent water from entering the bag body.

[0022] The main bag 1 contains multiple sub-bags 2, which are detachably installed within the main bag 1. Each sub-bag 2 is used to categorize and store items with different functions, including a medical emergency kit 21, an emergency food kit 22, and a shelter supplies kit 23. The medical emergency kit 21 stores medical supplies, including medical gauze, elastic bandages, tape, gloves, wet wipes, scissors, tweezers, tourniquets, iodine swabs, elastic mesh caps, triangular bandages, adhesive bandages, safety pins, whistles, lists, and manuals. The emergency food kit 22 stores emergency food items such as compressed biscuits and bottled water. The shelter supplies kit 23 stores shelter supplies such as breathing masks, non-slip gloves, emergency blankets, and multi-functional flashlights. The medical emergency kit 21 has an internal waterproof layer to prevent liquid leakage.

[0023] The mother bag 1 can also contain a rescue tool bag 24, a fire extinguisher bag 25, an escape rope bag 26, etc., as needed. The rescue tool bag 24 is used to store tools such as an emergency shovel; the fire extinguisher bag 25 is used to store fire extinguishers; and the escape rope bag 26 is used to store escape ropes.

[0024] The sub-pack 2 is attached to the inside of the mother pack 1 using Velcro, which includes a hook side and a loop side. The hook side is sewn onto the back of the sub-pack 2, and the loop side is sewn onto the back panel of the mother pack 1. Each sub-pack 2 corresponds to a loop side area, the size of which matches the hook side of the sub-pack 2. Users can remove specific sub-packs 2 as needed. For example, in a medical emergency, the user can directly remove the medical emergency kit 21 without opening other sub-packs 2. After use, the sub-pack 2 is returned to its original position and pressed to re-secure it. This mother-and-child pack 1 structure is based on a modular principle, breaking down complex tasks into simple operations and reducing cognitive load.

[0025] Of course, the sub-bag 2 and the mother bag 1 can be connected by other fixing devices, allowing the sub-bag 2 to be taken out and put back into the mother bag 1 separately. For example, strong magnets or magnetic snaps can be installed at corresponding positions on the sub-bag 2 and the mother bag 1, or elastic cords can be used inside the mother bag 1 to hold and fix the sub-bag 2, or webbing can be sewn onto the sub-bag 2 and a corresponding webbing loop can be found inside the mother bag 1, which can be fixed by a standard snap fastener (such as a D-ring or trapezoidal snap).

[0026] Preferably, the back of the sub-pack 2 has a hook-and-loop fastener, while the looped side of the fastener covers the entire back panel of the mother pack 1. Compared to having only a few fixing points inside the mother pack 1, the looped side of the fastener covering the entire back panel forms a large adhesive area. Users can freely arrange and adjust the sub-pack 2 at any position inside the mother pack 1 according to its size, shape, and personal habits. Users can also easily add, remove, or rearrange the sub-pack 2, giving the pack interior the autonomy to freely combine, fix, and expand. This allows manufacturers and users to flexibly combine and expand the pack according to their needs. For example, the most frequently used medical emergency kit 21 can be placed in the most convenient upper-middle position; the heavier rescue tool kit 24 can be placed at the bottom to lower the center of gravity and improve carrying comfort. When it is necessary to add or remove functional modules, simply tear off or attach the corresponding sub-pack, achieving "plug-and-play" functional expansion. The ergonomic principle behind this design is to optimize the operating path by placing frequently used items in the most accessible area, significantly reducing the time and actions required for searching and retrieving them.

[0027] The mother-and-child bag structure allows items to be categorized and stored in different child bags according to their functions. Users can quickly retrieve the entire child bag as needed without having to search inside the mother bag, improving retrieval efficiency and saving valuable time in emergency situations. The child bags are detachable and re-secured, allowing users to configure the type and number of child bags according to their personal needs or specific scenarios. This flexibility makes the bag highly adaptable.

[0028] The multiple sub-packs 2 are all different colors, used to distinguish their functions. Specifically, the medical emergency pack 21 is green, the emergency food pack 22 is red, the refuge supplies pack 23 is yellow, the rescue tool pack 24 is black, the fire extinguisher pack 25 is orange, and the escape rope pack 26 is blue. In practice, the colors of the sub-packs 2 can be adjusted as needed; there are no fixed color restrictions for each sub-pack 2. For example, the medical emergency pack 21 is not limited to green and can use other colors, and the same applies to the other sub-packs 2.

[0029] In a simulated test, a traditional emergency kit and the combined carrying bag of this invention were compared. The test scenario was a nighttime earthquake following an earthquake, where the user needed to retrieve a first-aid kit, flashlight, and escape rope. The traditional kit had an average retrieval time of 45 seconds, while the combined carrying bag had an average retrieval time of 15 seconds, improving efficiency by 67%. Color coding further reduces recognition time; in visual search tasks, color differentiation reduces the recognition error rate by 80%.

[0030] In this embodiment, the medical emergency kit 21, emergency food kit 22, refuge supplies kit 23, and rescue tool kit 24 all use zippered open pockets, while the fire extinguisher kit 25 and escape rope kit 26 use pull-out pockets. In practice, the sub-packs 2 can use pull-out pockets, zippered open pockets, flap bags, folding bags, or hard-shell boxes. Different items have their optimal storage form. Pull-out bags are suitable for flat tools, flap bags facilitate the organization of small items, hard-shell boxes provide top-level protection, and folding bags allow for flexible expansion. By matching the most suitable structure to the sub-packs 2 for different functions, optimal protection of the internal items, maximum access efficiency, and optimal space utilization are achieved.

[0031] like Figure 1 The front panel inside the mother bag 1 is fixed with a disaster prevention hood 3. The disaster prevention hood 3 is made of fire-resistant material, such as aramid fabric. After being folded, it is fixed to the front panel inside the mother bag 1 by an elastic band, which can ensure that the hood does not loosen during vibration.

[0032] The body of the mother bag 1 is made of a molded shell, which gives the body a fixed shape and high rigidity, can resist a certain degree of external pressure, and can effectively protect the contents inside the bag.

[0033] See Figure 2 and Figure 4The exterior of the main bag 1 is equipped with identification markings, including reflective strips 4 and / or an inventory list icon 5. At night or in low-light conditions, the reflective strips emit a bright light with the aid of external light sources, effectively alerting vehicles or rescue personnel and enhancing the user's passive safety. The inventory list icon 5 allows the user to quickly and easily identify the contents of the bag. Additionally, the identification markings include an "Emergency Kit" label printed on the front of the main bag 1, which may use fluorescent paint for visibility in low-light conditions.

[0034] See Figure 2 The top of the main bag 1 is equipped with a handle 7 for easy carrying. The handle 7 is made of double-layered nylon straps with embedded plastic support strips to improve load-bearing capacity. According to ergonomic studies, the width of the handle 7 is within the range of 4-6cm to minimize hand pressure.

[0035] See Figure 3 The two shoulder straps 8 of the main bag 1 are connected to the rear of the bag body. The shoulder straps 8 are filled with thick foam padding, providing excellent cushioning and effectively reducing shoulder pressure during prolonged carrying. Multiple horizontal webbing straps 9 are provided on the shoulder straps 8, allowing for flexible attachment or removal of various accessories, such as helmets, ropes, and ice axes, expanding the bag's carrying capacity. Small compartments are provided on the shoulder straps 8, forming storage pockets 10 between the small compartments and the shoulder straps 8, which can be used to store small items such as mobile phones and keys. The storage pockets 10 are optimized in position, located on the front side of the shoulder straps 8, for easy one-handed operation.

[0036] See Figure 3 The back of the main bag 1 is provided with a thickened layer 11, made of cushioning materials such as high-density sponge and EVA foam. This layer can effectively distribute the weight of the backpack on the back and shoulders, reducing fatigue when carrying it, and is especially suitable for long-term carrying. In addition, this thickened layer 11 acts as a cushioning layer, preventing hard objects from bumping against the user's back during walking or running, thus improving comfort and safety.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
