Abstract

This invention relates to a backpack unfolding structure. The main structure consists of a back panel formed at the top of the main body, a bottom panel connected to the bottom of the back panel, a front panel connected to the other end of the bottom panel, and a cover panel connected to the top of the front panel. Corresponding side panels are connected to both sides of the back panel of the main body, and the outer edges of the main body and the side panels are connected and fixed using connectors. This allows the backpack to be fully unfolded and laid flat, facilitating easy cleaning of the interior and preventing foreign objects or food scraps from accumulating inside, thus maintaining the cleanliness of the backpack's interior and enhancing its overall practicality.

Description

Backpack unfolding structure

This invention relates to a backpack unfolding structure, specifically a backpack unfolding structure that allows the backpack to be fully unfolded and laid flat, facilitating easy cleaning of the inside of the backpack and preventing foreign objects or food scraps from accumulating inside, thus effectively maintaining the cleanliness of the backpack's interior. This innovative backpack unfolding structure enhances the practicality of the backpack in its overall use.

Note that when people of all ages and genders go out, whether they are going to class, going to work, shopping, going on a picnic, traveling, hiking, or cycling, they often see the use of various types of backpacks to conveniently store and carry their personal belongings. There are various backpacks with different appearances and types on the market, allowing users to choose the appropriate type according to different usage scenarios.

Regardless of the type of backpack, they generally have a main storage compartment for items. The user can place various items in the storage compartment, and there is a corresponding opening. When the user needs to access the items placed in the storage compartment, they simply open the opening and then search for and retrieve the required items.

However, while these backpacks achieve the intended function of storing items, in actual use, it has been found that they can only be opened at the top for storing and retrieving items inside. They cannot be fully unfolded, making it easy for various kinds of dirt to accumulate inside. This is especially true when elementary school students use these backpacks as school bags, often storing small stationery items (such as paperclips) or snacks inside. As a result, stationery or snack crumbs easily accumulate in the gaps inside the backpack, making cleaning extremely inconvenient. Therefore, there is still room for improvement in the overall structural design.

Today, recognizing this need, the creators, drawing upon their extensive design, development, and production experience in the relevant industry, have further researched and improved upon existing technologies to provide a backpack unfolding structure that aims to achieve greater practical value.

The main purpose of this invention is to provide a backpack unfolding structure that allows the backpack to be fully unfolded and laid flat, making it easy to clean the inside of the backpack. This prevents foreign objects or food scraps from accumulating and getting stuck inside the backpack, thus effectively maintaining the cleanliness of the backpack's interior and enhancing its overall practicality in use.

The main purpose and function of the unfolding structure of this creative backpack are achieved through the following specific technical means:

Its main components include backpacks; among which:

The backpack has a main body with a back panel at the top and a bottom panel at the bottom. A front panel is formed at the other end of the bottom panel, and a cover is formed at the top of the front panel. Corresponding side panels are formed on both sides of the back panel of the main body, and the outer edges of the main body and the two side panels are connected and fixed by connectors.

A preferred embodiment of the unfolded structure of this creative backpack, wherein the connector is a double-ended zipper.

In a preferred embodiment of the unfolded structure of this creative backpack, limiting fasteners are provided on both sides of the front panel of the main body and the front end of the side panel, corresponding to the outer side of the connector.

To more fully and clearly reveal the technical content, creative purpose, and effects achieved in this work, a detailed explanation is provided below, along with the accompanying drawings and figure numbers:

First, please refer to the schematic diagram of the three-dimensional unfolding structure of the first work, the schematic diagram of the two-dimensional unfolding structure of the second work, and the schematic diagram of the three-dimensional combination structure of the third work. This work mainly includes a backpack (1); wherein:

The backpack (1) has a main body (11), a back panel (111) formed at the upper end of the main body (11), a bottom panel (112) connected to the bottom end of the back panel (111), a front panel (113) connected to the other end of the bottom panel (112), and a cover panel (114) connected to the upper end of the front panel (113). 11) Corresponding side panels (12) are provided on both sides. The outer edge of the main body (11) and the outer edges of the two side panels (12) are connected and fixed by a connector (13). The connector (13) can be a double-ended zipper. In addition, a limit fastener (14) is provided on both sides of the front plate (113) of the main body (11) and the front end of the side panel (12) corresponding to the outer side of the connector (13).

In this way, the backpack (1) is connected and fixed between the outer edge of the main body (11) and the outer edges of the two side bodies (12) using the connector (13). When the connector (13) is pulled down to open the cover (114) of the main body (11) [please also refer to the fourth figure showing the usage state of the invention], the user can store and retrieve various items inside the backpack (1). During the process of pulling down the connector (13), the connector (13) is stopped and limited by the limiting buckle (14) so as to control the connector (11). 3) Pull down to the appropriate position; when you want to clean, you can unfasten the limiting buckle (14) [please refer to Figure 5 for the schematic diagram of the limiting buckle unfastened state], so that the connector (13) is completely pulled down to the bottom of the two side pieces (12) [please refer to Figure 6 for the schematic diagram of the connector pulled down], at this time the main piece (11) and the two side pieces (12) of the backpack (1) can be fully unfolded and flattened, so as to facilitate the cleaning of the inside of the backpack (1) and prevent foreign objects or food scraps from accumulating and getting stuck in the gaps inside the backpack (1).

Based on the above description of the structure and usage of this invention, it can be seen that, compared with existing structures, this invention mainly allows the backpack to be fully unfolded and laid flat, making it easy to clean the inside of the backpack. This prevents foreign objects or food scraps from accumulating and getting stuck inside the backpack, thus effectively maintaining the cleanliness of the backpack's interior and enhancing its overall practicality in use.

The foregoing embodiments or diagrams are not intended to limit the structural form of this work. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this work.

In conclusion, this invention embodiment can indeed achieve the intended use effect, and the specific structure disclosed therein has not only never been seen in similar products, but has also not been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law. Therefore, I hereby file an application for a new type of patent and earnestly request your kind consideration and permission to grant the patent. I would be truly grateful for your assistance.
