Detailed Implementation

[0033] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0034] See Figures 1 to 4 As shown, this utility model discloses a multi-functional transformable bag, including an outer bag 1 and an inner bag 2. The inner bag 2 is detachably placed inside the outer bag 1, and the inner bag 2 serves as the basic storage function of the bag for placing items. The outer bag 1 is a deformable structure, and the functionality of the multi-functional transformable bag can be expanded by deforming the outer bag 1. When used as a backpack or other basic bag, the outer bag 1 protects the inner bag 2 and the items inside it. It also has accessories such as shoulder straps and handles, which allow the transformable bag to be converted into a backpack with handles.

[0035] The outer bag 1 includes a body 10 made of flexible material. The body 10 is a long strip-shaped sheet structure. The flexible long strip-shaped sheet structure makes it easy to fold the body 10. Combined with necessary connecting structures, it maintains its folded shape, thereby forming a cavity to accommodate the inner bag 2.

[0036] In this embodiment, the main body 10 is a rectangular fabric made of textile. In other embodiments, the main body 10 may also be made of other flexible materials, such as silicone, and the shape is not limited to a rectangle. It may be irregular in shape, such as a rectangular structure with arc-shaped ends.

[0037] The main body 10 has a length direction, a width direction, and a thickness direction. The main body 10 includes opposing inner surfaces 101 and outer surfaces 102 in its thickness direction. The two ends of the main body 10 in its length direction are defined as ends, and the two sides of the main body 10 in its width direction are defined as sides. The main body 10 is folded towards the direction of the inner surfaces to form an outer bag 1, and the ends of the main body 10 form the tops of the outer bag 1. The outer surfaces 102 of the main body 10 are provided with end connecting structures 3 for detachably connecting the ends of the main body 10. The two sides of the main body 10 are respectively provided with side connecting structures 4 for detachably connecting the sides of the main body 10.

[0038] This invention features an outer bag 1 and an inner bag 2. The inner bag 2 is used for storage, ensuring that the multifunctional deformable bag retains its basic storage function even after the outer bag 1 is unfolded and deformed. The outer bag 1 is a deformable structure, and the flexible material body 10 can enhance its functionality by utilizing its flexible, easily foldable, and deformable characteristics. When used as an outer bag, it is folded inwards towards the inward side 101 and connected by the end connecting structure 3 and the side connecting structure 4, thus forming a bag structure that can accommodate the inner bag 2. When other functions are required, the end and side connections can be disassembled to restore the flat structure, facilitating the expansion of its functionality through other connecting structures. For example, the flat body can be used as a mat. In addition, the body 10 can also be used as a stretcher, raincoat, sleeping bag, hammock, or backpack for transporting people, etc. The specific structure will be detailed later.

[0039] The end connection structure 3 includes a first connecting strap 31, with a first buckle 32 at its end. The first connecting strap 31 is connected to its end by means of the first buckle 32, thereby connecting the top of the outer bag 1. The first connecting strap 31 is a high-strength webbing, and the first buckle 32 is a snap-lock with a D-ring. Webbing and snap-locks with D-rings are existing technologies, commonly used in bags. In this embodiment, webbing and snap-locks with D-rings are used to form the end connection structure 3 of the main body 10, which can adjust the distance between the two ends of the main body 10. In this embodiment, the two ends of the main body 10 are partially overlapped, thereby reliably closing the opening at the top of the outer bag 1, preventing items from falling out of the opening at the top of the outer bag 1, and also providing a certain anti-theft function. The first connecting strap 31 extends along the length of the main body 10 and is sewn onto the outer side of the main body 10. Two first connecting straps 31 are spaced apart along the width of the main body 10, which can play a certain load-bearing role, increasing the strength and load-bearing capacity of the outer bag 1.

[0040] The side connection structure 4 includes multiple connection holes 41 and a second connection band 43 with a second buckle 42 at the end. The multiple connection holes 41 are spaced apart along the length of the main body 10 on the side of the main body 10. The second connection band 43 passes through the connection holes 41 in sequence and is connected to its two ends by the second buckle 42, thereby forming a detachable connection on the side of the main body 10. In this embodiment, the second latch 42 is the same as the first latch 32, both being interlocking latches with D-rings, which facilitates adjustment of the length of the second connecting strap 43. Both the second connecting strap 43 and the first connecting strap 31 are high-strength webbing. When the inner bag 2 contains fewer items, in order to prevent the inner bag 2 from falling out from the side of the outer bag 1, the second connecting strap 43 can be adjusted to be shorter so that the side of the main body 10 is closer. Correspondingly, when the inner bag 2 contains more items, in order to insert the inner bag 2 into the outer bag 1, the second connecting strap 43 can be adjusted to be longer so that the side of the main body 10 is farther away, that is, the side opening of the outer bag 1 is larger, and the second connecting strap 43 is used to prevent the inner bag 2 from falling out.

[0041] In this embodiment, the second connecting strap 43 is a continuous strip that passes sequentially through the connecting holes 41 to connect the sides of the main body 10. To facilitate the unfolding of the main body 10, the second connecting strap 43 should be removable from the connecting holes 41, or the second connecting strap 43 should be long enough that the unfolding of the main body 10 is not limited by the length of the second connecting strap 43. In this embodiment, the connecting hole 41 is formed by ropes sewn to the main body 10 at both ends. The connecting hole 41 can be relatively large, and since no hole is made in the main body 10, the presence of the connecting hole 41 does not reduce the strength of the main body 10. Of course, in other embodiments, the connecting hole 41 can also be formed by opening a through hole in the main body 10, simplifying the form of the connecting hole 41.

[0042] The end connection structure 3 and the side connection structure 4 are not limited to the forms described above. The end connection structure 3 can also be ropes located at both ends of the main body 10, with the two ends of the main body 10 connected by knotting the two ropes. In addition, in some cases, the end connection structure 3 can also be zippers located at both ends of the main body 10, making the top opening of the outer bag 1 more reliably closed. The side connection structure 4 can also be multiple Velcro straps located on the sides of the main body 10, connecting the sides of the main body 10 by fastening the Velcro straps, so that the folded main body 10 forms a complete outer bag 1.

[0043] The outer side 102 of the main body 10 is divided into a front region 102a and a rear region 102b along its length. The front region 102a is provided with two shoulder straps 103, and the rear region 102b is provided with an accessory pocket 104. The accessory pocket 104 cooperates with the outer side 102 of the main body 10 to form an accessory storage cavity. This accessory storage cavity can expand the storage space and function of the outer bag 1. For example, placing a portable sterilization device in the accessory storage cavity can enable the multifunctional transformable bag to have a sterilization function.

[0044] like Figure 5 As shown, in remote or other environments with poor transportation, if an injured person needs to be carried, the inner bag 2 can be removed, the opening at the top of the outer bag 1 can be opened, and the injured person can sit inside the outer bag 1 in the space originally used to hold the inner bag 2. Because the two first connecting straps 31 are spaced apart, the injured person's head can protrude between the two first connecting straps 31. Since the sides of the main body 10 are detachably connected by the side connecting structure 4, the side connecting structure 4 can be opened or locked depending on the situation (the injured person's size, the severity of the injury, etc.). Figure 5 The image shows the removal of the second connecting strap 43 from the side connecting structure 4, allowing the injured person more room to move.

[0045] like Figure 6 and Figure 7 As shown, in order to carry this multi-functional transformable bag more easily, this utility model also has a detachable and installable pull bracket 5, so that the multi-functional transformable bag can be formed into a pull cart. Specifically, the outer side 102 of the main body 10 is provided with a reinforcing layer 105, which is located between the two shoulder straps 103 and does not affect the carrying function of the multi-functional transformable bag when used as a backpack. A reinforcing hole is formed between the reinforcing layer 105 and the outer side 102 of the main body 10. The pull bracket 5 includes a support frame 51 and a connecting frame 52, which are perpendicular to each other. The support frame 51 is used to place the multi-functional transformable bag, and the bottom of the support frame 51 is provided with a roller 53. The connecting frame 52 passes through the reinforcing hole between the reinforcing layer 105 and the outer side 102 of the main body 10, and the end of the connecting frame 52 away from the support frame 51 forms a handle 54 for pulling the multi-functional transformable bag by hand. The presence of the pull bracket 5 broadens the application scenarios of this invention. Users can decide whether to install the pull bracket 5 based on the intended use scenario. For example, in environments with relatively flat roads, such as cities, the pull bracket 5 can be installed to form a handcart, reducing the burden of carrying this multi-functional transformable bag. In addition, the connecting frame 52 can also be equipped with rollers 53. The rollers on the connecting frame 52 are arranged in a triangular pattern, allowing the handcart to be used on stairs and uneven roads with the help of the triangularly arranged rollers 53.

[0046] like Figure 8 and Figure 9As shown, in one embodiment, the main body 10 can be used as a raincoat after unfolding and deforming. For this purpose, the main body 10 has a neck loop 106a in its central region 102c along its length. A flexible rain cap 106b is provided at the edge of the neck loop 106a. An openable and closable flap 106c is provided on the inner side 101 of the main body 10. The flap 106c is used to selectively open and close the neck loop 106a. The main body 10 is made of waterproof material or has a waterproof coating, thus enabling it to be used as a raincoat. If necessary, the main body 10 can also be configured as a double-layer structure, unfolding along its width to both sides (the dotted line in the figure shows the outline of the unfolded main body 10), increasing the width of the main body 10, thereby increasing the width of the raincoat and increasing the coverage area. The central region 102c refers to the region that is a certain distance from both ends along the length of the main body 10, more preferably located in the exact middle of the main body 10 along its length. In this embodiment, it refers to the region between the front region 102a and the rear region 102b.

[0047] like Figure 4 As shown, in one embodiment, the main body 10 has multiple flexible handles 107 on its side, which are spaced apart along the length of the main body 10, so that the unfolded main body 10 forms a soft stretcher. In use, the inner side 101 of the main body 10 faces upwards for the injured person to lie down, and the flexible handles 107 serve as grips for other people to move the soft stretcher. Because the main body 10 is flexible, to ensure the stability of the injured person on the soft stretcher, the flexible handles 107 are symmetrically arranged on both sides, and the total number of flexible handles 107 is eight, allowing eight people to each grip one flexible handle 107 to move the soft stretcher. Because the handles 107 are flexible, when the main body 10 is folded to form an outer bag 1, the flexible handles 107 can fold inwards without affecting the use of the outer bag 1. Specifically, the flexible handles 107 are formed by strips of fabric sewn to the sides of the main body 10 at both ends. In other embodiments, the connection between the flexible handles 107 and the main body 10 can also be through holes at both ends passing through the main body 10.

[0048] When there are insufficient personnel, rigid poles can be used to assist in moving the soft stretcher, such as... Figure 10 As shown, two rigid rods 6 are passed through the flexible handles 107 on one side in sequence, and four people operate the two ends of the rigid rods 6 to move the soft stretcher.

[0049] like Figure 11As shown, in another embodiment, the side of the main body 10 is provided with a plurality of connecting through holes 108, which are arranged at intervals along the length of the main body 10. The connecting through holes 108 are used to detachably connect the side carrying straps 7, so that the main body 10 in the unfolded state and the side carrying straps 7 cooperate to form a side-carrying stretcher. In use, the person carrying the stretcher stands on one side of the main body 10 close to one of the side carrying straps 7 and carries the side carrying strap 7 on their shoulder, while holding the other side carrying strap 7 by hand to prevent the injured person from falling off the main body 10. There are four side carrying straps 7, symmetrically arranged on both sides of the main body 10. In this way, only two people are needed to move the side-carrying stretcher.

[0050] like Figure 12 As shown, in another embodiment, the side edge of the main body 10 has a double-layer structure. Along the length of the main body 10, both ends of this double-layer structure are open, thus forming a flexible sleeve extending along the length of the side edge of the main body 10. Two flexible ropes 8 are passed through this flexible sleeve, and the ends of the flexible ropes 8 are suspended and fixed. The unfolded main body 10 can then be used as a hammock, with the inner side 102 facing upwards during use. Furthermore, this flexible sleeve can also be passed through... Figure 10 The rigid rod 6 shown makes the unfolded main body 10 cooperate with the rigid rod 6 to form a stretcher.

[0051] like Figure 13 and Figure 14 As shown, in another embodiment, the main body 10 has a double-layer structure with an opening at one end, thus forming a sleeping bag. In use, the user lies inside the double-layered main body 10, with their head protruding from the opening at the end, serving as a camping sleeping bag. Furthermore, to facilitate user access to the sleeping bag, except for the opening at the end, the edges of the sleeping bag are secured with hook and loop fasteners 9 (specifically, Velcro), allowing for a more body-hugging design. The dotted lines in the figure represent the unfolded portion of the sleeping bag.

[0052] It should be noted that, for the sake of clarity, the outer bag 1 is drawn as a square after being folded in the attached diagram. In actual use, since the main body 10 is made of flexible material, it will deform according to the weight of the items it supports or the injured person.

[0053] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
