Description
Technical Field
[0001] This utility model relates to the field of backpack technology, specifically a multi-purpose backpack. Background Technology
[0002] As people's lifestyles become increasingly diversified, their functional demands for backpacks are also becoming more diverse and specific, no longer limited to basic load-bearing functions. However, most existing backpack products suffer from limited functionality and insufficient adaptability to different scenarios. Most backpacks focus only on storage capacity or basic carrying comfort, making it difficult to flexibly meet the differentiated needs of various scenarios such as commuting, outdoor activities, and short trips. Against this backdrop, new backpacks with multiple practical functions have gradually become a hot topic in market research and development.
[0003] Utility model patent CN220694629U discloses a multi-functional backpack. This multi-functional backpack includes a carrying frame, two shoulder straps, a folding flap, a first movable bag, and a second movable bag. The two shoulder straps are attached to the carrying frame. One end of the folding flap is located at the bottom of the carrying frame, and the other end can be connected to the top of the carrying frame. The first movable bag is vertically mounted on the carrying frame and has a first compartment. The second movable bag is also vertically mounted on the carrying frame and has a second compartment. The first and second movable bags can be folded away from each other to form an expanded compartment between the folding flap and the carrying frame. This multi-functional backpack can expand its capacity by folding the first and second movable bags to create an expanded compartment, while also preventing items from being squeezed or collided, greatly improving its practicality.
[0004] The aforementioned patent provides a multi-functional backpack that can expand its space, but its core focus remains on the single function of expanding storage capacity. In actual use, users' needs in specific scenarios are often more complex, especially in outdoor activities. People not only need to carry outdoor equipment such as tents, sleeping bags, and water bottles in their backpacks, but also often need camping mats for resting. Currently, backpacks on the market do not integrate the function of "expanding into a camping mat," requiring users to carry a separate camping mat, which increases the burden on their backs and may lead to loss or damage of the camping mat due to improper storage, causing many inconveniences for outdoor activities. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-purpose backpack, which aims to improve the problem that existing backpacks have only one function, focusing only on storage needs and failing to integrate camping mat functions, resulting in users having to carry an extra camping mat during outdoor activities, which is heavy and inconvenient to use.
[0006] This utility model is implemented as follows: A multi-purpose backpack includes a rectangular piece of fabric with at least two equidistant horizontal fold lines and two vertical fold lines, which divide the rectangular fabric into at least nine planar areas. A flap is located at the top of the rectangular fabric above the two vertical fold lines. A first side pull and a second side pull are sewn sequentially from top to bottom along the two vertical fold lines. The first or second side pull is equipped with a zipper pull. When the rectangular fabric is folded sequentially according to the design sequence until the first and second side pulls overlap and align, the zipper pull is pulled up or down to form a bag body. A bag opening is formed below the flap. When the first and second side pulls are opened, the bag body can be unfolded into a camping mat.
[0007] Preferably, the bag cover is fastened to the bag body, the back of the bag body is symmetrically provided with shoulder straps on both sides, the back of the bag body is provided with an adjustment strap at the bottom, the adjustment strap and the shoulder strap are connected by a D-ring buckle, and the back of the bag body is provided with a handle at the top, the handle is covered with a layer of cushioning cotton padding.
[0008] Preferably, the bottom end of the shoulder strap is provided with a connector, which is connected to a D-ring buckle. One end of the adjustment strap passes through the D-ring buckle, and the length of the structure composed of the shoulder strap and the adjustment strap can be adjusted through the D-ring buckle.
[0009] Preferably, the inner side of the bag cover is provided with a first storage bag, the opening end of the first storage bag is provided with a first zipper, the end of the first zipper is provided with a first pull tab, and the first zipper and the first pull tab are used to open and close the first storage bag.
[0010] Preferably, the edge of the bag cover is provided with a edging, the bag cover is provided with a plurality of female snap fasteners, and the bag body is provided with male snap fasteners at the positions corresponding to the female snap fasteners.
[0011] Preferably, the front bottom of the bag body is provided with a second storage bag, the opening end of the second storage bag is provided with a second zipper, and the end of the second zipper is provided with a second pull tab.
[0012] Preferably, the package body is woven from high-density polyester fibers and the surface is treated with a waterproof coating.
[0013] Preferably, the inner side of the shoulder strap is filled with cushioning cotton, and the inner side of the shoulder strap is sewn with a mesh-like breathable fabric.
[0014] Preferably, the bag body has a side pocket on the bottom side of the front, and the top of the side pocket has an opening.
[0015] Preferably, the package body is provided with a limiting band at the top opening of the side pocket, the bottom end of the limiting band is provided with a male fastener, and the top side of the side pocket is provided with a female fastener, the male fastener and the female fastener are fastened together.
