[0043] Large backpacks currently on the market (such as mountaineering bags, travel bags, etc.) are usually equipped with a carrying frame to enhance comfort and distribute the load when carried. However, these backpacks with carrying frames have a common problem - the carrying frame is relatively high, and the carrying frame is fixed to the backpack, making it difficult to remove from the backpack, resulting in the backpack and the carrying frame taking up a large space when stored. For users, when not in use, the backpack and the carrying frame still take up a large space, making it difficult to find a suitable storage location, inconvenient to store and carry, and affecting the user experience. For production lines, the taller carrying frame is not easy to operate on the production line, especially in the assembly and packaging links, which will lead to low production efficiency and increased costs. For logistics and transportation, it will take up a large space when stacked, making it inconvenient to stack, and increasing logistics costs.
[0044] Based on the above problems, an embodiment of the present invention provides a foldable bracket and a backpack. The backpack is equipped with a foldable bracket, which is assembled and connected to the backpack before use and disassembled or folded together after use. It is convenient, flexible and easy to store and carry. It will be described in detail below.
[0045] Please refer to Figures 1 to 4 The foldable stand includes a folding portion 1, a first frame 2, and a second frame 3. The first frame 2 is provided with a first connection point 221 for connecting to a backpack, and the second frame 3 is provided with a second connection point 321, which is also used to connect to the backpack, thereby positioning the backpack on the stand. At least a portion of the folding portion 1 is connected to the first frame 2 and the second frame 3, and the first frame 2 and / or the second frame 3 can be folded around the folding portion 1. When folding and storing, the first frame 2 is folded relative to the second frame 3, or the second frame 3 is folded relative to the first frame 2, thereby reducing the size of the entire stand for easy carrying and storage.
[0046] In this embodiment, the folding portion 1 is a rotating axis, the first frame 2 is provided with a first rotating hole 201, and the second frame 3 is provided with a second rotating hole 301. The rotating axis is inserted into the first rotating hole 201 and the second rotating hole 301 at the same time. The first frame 2 and the second frame 3 can both rotate around the rotating axis to complete the folding.
[0047] In other embodiments, the folding portion 1 can also be made of elastic material or memory metal, and can return to its original shape after bending. The first frame 2 and the second frame 3 are respectively connected to the two sides of the folding portion 1. For example, the folding portion 1 is made of elastic rubber or silicone.
[0048] refer to Figure 5 and Figure 6The first frame 2 includes a first rotating portion 20 and a first plugging portion 22. The first plugging portion 22 is fixed to the first rotating portion 20. The first connecting position 221 is provided on the first plugging portion 22. The first rotary hole 201 is provided on the first rotating portion 20. The second frame 3 includes a second rotating portion 30 and a second plugging portion 32. The second plugging portion 32 is fixed to the second rotating portion 30. The second connecting position 321 is provided on the second plugging portion 32. The second rotary hole 301 is provided on the second rotating portion 30.
[0049] In this embodiment, the first rotating part 20 and the second rotating part 30 are both cylindrical, the first plug-in part 22 and the second plug-in part 32 are both V-shaped blocks, the first plug-in part 22 is fixed on the outer wall of the first rotating part 20, and the second plug-in part 32 is fixed on the outer wall of the second rotating part 30.
[0050] In this embodiment, the first rotating portion 20 and the first plug-in portion 22 are integrally formed, and the second rotating portion 30 and the second plug-in portion 32 are also integrally formed. Integral forming can reduce manufacturing difficulty, shorten the manufacturing process, and help reduce the complexity of the entire bracket.
[0051] Of course, in other embodiments, the first rotating portion 20 and the first plugging portion 22 as well as the second rotating portion 30 and the second plugging portion 32 may also be manufactured separately and then connected by welding, bonding, or bolts.
[0052] The first rotating part 20 includes a first docking end face 202, and the second rotating part 30 includes a second docking end face 302. The first docking end face 202 and the second docking end face 302 can be snap-connected to lock the first rotating part 20 and the second rotating part 30 together, thereby keeping the first plug-in part 22 and the second plug-in part 32 unfolded for connection with a backpack. The first docking end face 202 and the second docking end face 302 can also be separated from each other to unlock and separate the first rotating part 20 and the second rotating part 30, so that the first frame 2 and the second frame 3 can both rotate around the rotating axis, thereby folding the first frame 2 and the second frame 3 together, reducing the size of the entire bracket for easy carrying and storage.
[0053] More specifically, the first docking end face 202 is a concave-convex surface, the second docking end face 302 is also a concave-convex surface, and the second docking end face 302 is adapted to the first docking end face 202. When the first docking end face 202 and the second docking end face 302 are connected, the first rotating part 20 cannot rotate relative to the second rotating part 30. In this embodiment, the first rotating part 20 and the second rotating part 30 are locked and unlocked by axially moving around the rotation axis.
[0054] In other embodiments, the first rotating part 20 may be provided with a protruding plug-in block, and the second rotating part 30 may be provided with a groove. The plug-in block matches the groove and can be inserted into the groove to lock the first rotating part 20 and the second rotating part 30. In this embodiment, the first rotating part 20 and the second rotating part 30 can also be locked and unlocked by axially moving around the rotating axis.
[0055] For another example, both the first rotating part 20 and the second rotating part 30 are provided with strip grooves with corresponding sizes. The first rotating part 20 and the second rotating part 30 can be locked by installing appropriate strip blocks in the two strip grooves, and the first rotating part 20 cannot rotate relative to the second rotating part 30. In this embodiment, the first rotating part 20 and the second rotating part 30 can be locked and unlocked by installing strip blocks, and the first rotating part 20 and the second rotating part 30 do not need to move axially around the rotation axis.
[0056] The first rotating portion 20 and the second rotating portion 30 may be locked and unlocked in various other ways, which will not be described in detail here.
[0057] When the locking of the first rotating part 20 and the second rotating part 30 adopts the axial movement method around the rotating axis, the first docking end face 202 of the first rotating part 20 and the second docking end face 302 of the second rotating part 30 need to apply a pair of axial forces at both ends of the axial direction to prevent the first rotating part 20 and the second rotating part 30 from separating when in use. For this purpose, a locking member is provided to lock the first rotating part 20 and the second rotating part 30 when in use and unlock them when not in use.
[0058] refer to Figures 7 to 9 and combined Figure 3 In this embodiment, the locking members are a screw 40 and a nut 41, and the rotating shaft is a hollow round tube. The rod of the screw 40 passes through the rotating shaft and is connected to the nut 41; when the nut 41 is tightened, the nut 41 and the nut of the screw 40 are pressed against the outer end surfaces of the first rotating part 20 and the second rotating part 30, thereby locking the first rotating part 20 and the second rotating part 30.
[0059] Furthermore, a first stop block 401 is provided on the inner side of the nut of the screw rod 40, and a second stop block 411 is provided on the end face of the nut 41. The first stop block 401 is connected to the outer end face of the first rotating part 20, and the second stop block 411 is connected to the outer end face of the second rotating part 30; wherein, the outer end face of the first rotating part 20 is the other side end face opposite to the first docking end face 202, and the outer end face of the second rotating part 30 is the other side end face opposite to the second docking end face 302.
[0060] In other embodiments, the locking and unlocking of the first rotating portion 20 and the second rotating portion 30 may also be achieved by magnetic, snap-fit, or other locking methods. If a magnetic method is used, two magnets may be fixed to the first mating end face 202 of the first rotating portion 20 and the second mating end face 302 of the second rotating portion 30, respectively. When the first rotating portion 20 and the second rotating portion 30 need to be locked, the two magnets attract each other, thereby locking the first rotating portion 20 and the second rotating portion 30 together. If a snap-fit method is used, a female snap-fit buckle is provided on the first rotating portion 20 and a male snap-fit buckle is provided on the second rotating portion 30. When the first rotating portion 20 and the second rotating portion 30 need to be locked, the female snap-fit buckle and the male snap-fit buckle are connected.
[0061] Reference again Figure 2 In order to make the user feel comfortable when using the foldable bracket, one side surface of the first plug-in portion 22 is a plane, and one side surface of the second plug-in portion 32 is also a plane. The plane of the first plug-in portion 22 and the plane of the second plug-in portion 32 are located in the same plane, and the same plane is used to fit with the back of the person, so that the load is evenly distributed when carrying.
[0062] Furthermore, the height of the first plug-in portion 22 and the second plug-in portion 32 after being locked and extended is adapted to the height of a person's back, and the width is adapted to the width of a person's back.
[0063] Of course, the surface of the first plug part 22 and the second plug part 32 that connects to the back of the person can also be designed into an ergonomic shape. The height and width of the first plug part 22 and the second plug part 32 after being locked and extended can be adjusted, which will not be described in detail.
[0064] refer to Figure 10 The first connection position 221 on the first plug-in portion 22 is a plug-in hole, and the second connection position 321 on the second plug-in portion 32 is also a plug-in hole. When in use, the support rod is connected to the backpack by plugging the first connection position 221 and the second connection position 321. After use, the support rod can be removed from the first frame 2 and the second frame 3, thereby further reducing the size of the foldable bracket.
[0065] The support rods can be of various types. In this embodiment, the support rods are hard ring-shaped bars that plug into the sockets at both ends and connect to the backpack at the middle. The support rods can be left in place after use. The foldable stand and backpack can be folded together to reduce the overall height, making it easier to store and transport and more convenient for the user.
[0066] In this embodiment, the first frame 2 and the second frame 3 can be made of hard plastic, or other materials such as metal.
[0067] When the foldable stand of the present invention is needed, the first frame body 2 and the second frame body 3 are rotated to keep them extended and docked and locked; when not needed, the first frame body 2 and the second frame body 3 can be unlocked and folded in half, which is very convenient.
[0068] The foldable stand of the present invention has few components and can be folded and extended. For users, the height can be halved when not in use, making it easier to carry and store. For production lines, the first frame 2 and the second frame 3 can be manufactured separately and then assembled, resulting in a lower height, easier operation, and higher production efficiency. For logistics and transportation, the foldable stand can accommodate more products, reducing logistics costs.
[0069] refer to Figure 11 An embodiment of the utility model further provides a backpack, which includes the foldable bracket. When the bracket is removed from the backpack, the bracket can be folded in half to reduce the height of the bracket. At the same time, after the bracket is removed, the backpack itself no longer has a rigid support and can also be folded, thereby reducing the space occupied by the backpack as a whole and making it more convenient to carry and store.
[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
