A backpack that can serve as a seat

Abstract

This invention provides a backpack that can function as a seat, including a main compartment and a main support frame. The main support frame is located on both sides of the main compartment, supporting the height and thickness of the main compartment and allowing adjustment of the thickness-to-height ratio. A support rod connects between the two main support frames to support the width of the main compartment. This backpack, by using the main support frame and support rod to provide structural support in three directions, allows it to function as a seat. Furthermore, the scissor-like structure of the main support frame adjusts the thickness-to-height ratio of the main compartment. When used as a seat, the backpack thickness is increased while the height is decreased, resulting in a larger seating area and a suitable ground clearance, improving sitting comfort. Conversely, when carried normally, the backpack thickness is compressed to increase the height, improving carrying comfort.

Description

Technical Field

[0001] This utility model belongs to the field of backpack technology, specifically relating to a backpack that can be used as a seat. Background Technology

[0002] When traveling outdoors and needing to rest or while waiting for a vehicle, it is common to encounter situations where there are no seats available. Backpacks are almost always an essential item in such travel scenarios. Therefore, using backpacks as seats can greatly alleviate the aforementioned supply and demand imbalance.

[0003] For example, patent document with application number 202022907910.1 describes a multi-functional backpack for the elderly that can be sat on. Specifically, a foldable cushion is added to the backpack. When in use, the cushion is folded down from the back of the backpack and laid flat on the ground. This design is essentially a cushion to sit on the ground. Its only function is to prevent dust from getting on your pants. However, sitting cross-legged on the ground is not comfortable. Moreover, this design is essentially no different from carrying a cushion in an ordinary backpack. Therefore, its practicality is low.

[0004] For example, patent document with application number 202122628078.6 describes a multi-functional backpack for outdoor travel, which has a horizontally pull-out seat at the bottom of the backpack and a folding board at the bottom of the seat to act as a stool leg. However, this design has two problems. First, even if the seat is raised by the folding board, the height is very limited, and the actual sitting posture is still equivalent to sitting cross-legged on the ground, which is not very comfortable. Second, this design is equivalent to carrying an extra hard folding stool on the backpack, which will greatly increase the empty weight of the backpack and affect its practicality. It is even less convenient than carrying an external folding stool in a regular backpack. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a backpack that can be used as a seat, so as to solve the comfort problem of backpack seat without excessively increasing the weight.

[0006] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0007] A backpack that can be used as a seat includes:

[0008] Main bag;

[0009] The main support frame, located on both sides of the main bag, supports the main bag in both height and thickness directions, and allows adjustment of the thickness-to-height ratio of the main bag.

[0010] The support rod connects the two main supports and provides support in the width direction of the main bag.

[0011] Furthermore, the main support is a scissor structure, including two intersecting support rods, which are rotatably connected by a central shaft, and both ends of each support rod are connected to the main bag by side shafts.

[0012] Furthermore, the support rod includes:

[0013] Side support rods connect the two opposite side shafts;

[0014] The central support rod connects the two central axes.

[0015] Furthermore, the central support rod is a detachable two-section structure, which is swayably connected to the central shafts on both sides, and can swing to be connected and fixed to the side wall of the main bag.

[0016] Furthermore, the main support is provided with a limiting structure to restrict the opening and closing angle.

[0017] Furthermore, the opening and closing angle of the main support is limited by the pulling of the main bag.

[0018] Furthermore, the main bag is provided with a cover at the top.

[0019] Furthermore, one end of the bag flap is connected to the back of the main bag, and the other end is provided with two sets of connecting buckles;

[0020] The front of the main bag has a connection hole; two sets of connecting buckles are respectively connected to the connection hole at two thickness-height ratios of the main bag.

[0021] Furthermore, a base plate is provided on the top front of the main bag, and the two ends of the base plate are respectively connected to the support rod at the location via a pivot. The surface of the base plate is provided with the connection hole.

[0022] Furthermore, the two sections of the central support rod are connected by snap fasteners to each other and to the side wall of the main bag.

[0023] The beneficial effects of this utility model are as follows:

[0024] (1) This utility model provides a backpack that can be used as a stool. By setting a main support and a support rod, the backpack is structurally supported in the three directions of thickness, width and height, so that the backpack can be used as a stool for people to sit on. On this basis, the thickness-height ratio of the main bag of the backpack is adjusted by using the main support with a scissor structure. When used as a stool, the thickness of the backpack is increased and the height of the backpack is reduced, so that the backpack in the stool mode has a larger cushion area and a suitable height from the ground, thus improving the comfort of sitting posture. When carried normally, the thickness of the backpack is compressed and the height of the backpack is increased, thus improving the carrying comfort.

[0025] (2) In this utility model, the central support rod located in the middle area is designed as a two-section structure that can be separated. In the form of a stool, the two sections are joined together to act as a support rod to provide support in the width direction. In the form of a backpack, it is separated and folded up to facilitate the storage of items and at the same time plays a role in limiting and fixing the main bag to prevent the main bag from falling apart.

[0026] (3) In this utility model, the cover is set as a seat cushion for the stool, and two sets of connecting buckles are designed on it, which are used to connect and fix the main bag in the backpack form and the stool form respectively, and can play a pulling role on the main bag in each form, thereby improving the structural stability of the main bag in both forms.

[0036] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein similar or identical reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] like Figures 1 to 3The backpack shown includes a main compartment 1 made of flexible fabric, with main supports 3 symmetrically arranged on both sides to provide structural support for the shape of the backpack. Two shoulder straps are located on the back of the main compartment 1, and a flap 2 is attached to the top.

[0038] The main support frame 3 is a scissor-type structure, comprising two support rods 31. The two support rods 31 are intersecting and rotatably connected by a central shaft 32, allowing them to rotate relative to each other. Each support rod 31 is connected to the main bag 1 at both ends via side shafts 33. In use, the thickness-to-height ratio of the main bag 1 (i.e., the backpack) is changed by adjusting the opening angle of the support rods 31 on the main support frame 3, wherein:

[0039] (1) Stool shape: such as Figures 1-3 The image shows the seat configuration. In this state, by adjusting the opening angle of the main support 3, the backpack thickness increases and the height decreases, making it convenient for a person to sit on the top cover 2 of the backpack. In this embodiment, the opening angle of the main support 3 is limited by the fabric stretching at the top and bottom of the main bag 1 in the backpack thickness direction (similar to the principle of a stool), thereby providing support for the seat. In addition, the opening angle of the main support 3 can also be limited by setting a limiting structure on the main support 3 to achieve the seat function.

[0040] (2) Backpack shape: such as Figures 4-5 The image shows the backpack configuration. In this configuration, by adjusting the opening angle of the main support 3, the backpack thickness is compressed and the height is increased, making it easier for people to carry.

[0041] like Figure 3 As shown, in order to improve the support strength in the width direction of the backpack, a central support rod 35 is connected between the two central shafts 32 (if the central support rod 35 is not provided, the central shaft 32 does not need to be inserted into the inside of the main bag 1), and a side support rod 34 is connected between the two side shafts 33 that are opposite to each other.

[0042] like Figure 5 As shown, the central support rod 35 is a two-section splicing structure, with the left and right sections connected to the central shaft 32 on both sides via hinges. Specifically: 1) In backpack mode, the left and right sections of the central support rod 35 fold upwards and are connected to the side wall of the main bag 1 via buckles. This facilitates the storage of items and provides support and restraint for the fabric main bag 1, preventing it from loosening as the main support frame 3 moves into seat mode; 2) In seat mode, the left and right sections of the central support rod 35 fold flat and are connected and fixed via buckles, providing support in the width direction of the backpack.

[0043] like Figure 1 and Figure 2As shown, a base plate 11 is provided on the top of the front of the main bag 1 (the side away from the shoulder strap). Specifically, in this embodiment, both ends of the base plate 11 are rotatably connected to the support rod 31 at the corresponding position via base plate pivots 13. The surface of the base plate 11 is provided with connecting holes 12. One end of the cover 2 is connected to the back of the main bag 1 (the side with the shoulder strap), and the other end can be folded over to cover the base plate 11. The cover 2 is provided with two sets of connecting buckles 21, wherein: 1) Figure 1 As shown in the stool configuration, it is connected and fixed to the connecting hole 12 by a set of connecting buckles 21 located relatively at the front; 2) Figure 4 As shown in the backpack form, it is connected and fixed by a set of connecting buckles 21 located relatively at the rear and connecting holes 12.
