Description

Multifunctional backpack device

The present invention relates to a backpack device, in particular to a multifunctional backpack device that can be opened half or fully.

There are many bags on the market, such as backpacks, wallets, handbags, mobile phone bags, waist bags, etc., and the uses and storage spaces of various bags are different. Take side shoulder bags as an example. The storage space of side shoulder bags is limited by Due to the overall volume, there are restrictions. Items with a certain volume and length cannot be placed in the storage space, or there is no other space to place other items after being placed. In addition, the side must be opened when storing items. The shoulder bag can only be stored. It can be seen that the existing side shoulder bag is very inconvenient to access. Not only that, the items that can be stored are very limited. The main purpose of this creation is to place items of a certain volume and length (mobile phones) or sundries in the storage space through the storage openings on both sides of the body. In particular, the cover at the storage opening is used to fix the items in position to prevent them from slipping. Side shoulder bags with small storage space can store items or sundries with a certain volume and length through this invention, and they are not easy to fall out.

In addition, side shoulder bags are items that women often hang on their shoulders to carry items in their daily lives. Because they are obvious and exposed bags, and because they have shoulder straps that are easy to pull away, they are often targeted by unscrupulous gangsters. The target of the robbery. A general side shoulder bag has a shoulder bag body and shoulder straps hanging on both sides of the shoulder bag body. When used, it is hung on the shoulders. Therefore, gangsters usually use the method of directly pulling the shoulder straps to make the entire bag The shoulder bag is detached from the body. When a person wearing a shoulder bag is robbed, the person being robbed is often in danger of being dragged and injured due to the lateral force of the backpack being robbed, causing the shoulder strap to be pulled or being pulled in self-defense. However, the shoulder bags currently sold on the market have their shoulder straps and the body of the shoulder bag either fixed with suture technology or connected with fixed fasteners. Therefore, gangsters often succeed when robbed, and even lead to victims. It is unfortunate that people get injured due to shoulder strap pulling.

In addition, some backpacks use hard shells. The main purpose is to hold up the space inside the backpack and protect the items inside. However, the hard shells are not elastic and the opening must be fully opened to access the items inside. , it is not convenient to use.

It can be seen from the above description that current backpacks that can accommodate items have the following shortcomings:

1. Unable to classify items: The storage space of the side shoulder bag is limited by the overall volume. Items with a certain volume and length cannot be placed in the storage space, or there is no other space to place other items after they are placed. In addition, When storing items, the side shoulder bag must be opened for storage. It can be seen that the existing side shoulder bag is very inconvenient to access. Not only that, the items to be stored are very limited, and the items placed in the backpack are all located in the same location. It is not possible to place items into categories in a space.

2. The structure is single and cannot be separated: The general side shoulder bag has a single structure and cannot be separated. Since it is draped on the shoulder when used, gangsters usually use the method of directly pulling the shoulder strap to separate the entire shoulder bag from the human body during robbery. When a person wearing a shoulder bag is robbed, the person being robbed is often in danger of being dragged and injured due to the lateral force of the backpack being robbed, causing the shoulder strap to be pulled or being pulled in self-defense. However, the shoulder bags currently sold on the market have their shoulder straps and the body of the shoulder bag either fixed with suture technology or connected with fixed fasteners. Therefore, gangsters often succeed when robbed, and even lead to victims. It is unfortunate that people get injured due to shoulder strap pulling.

3. Inability to have both uses:

Generally speaking, the main purpose of using a backpack with a hard shell is to hold up the space inside the backpack and protect the items inside. However, the hard shell is not elastic and the opening must be fully opened to access the items inside. Therefore, although a backpack with a hard shell provides better protection, it is inconvenient to open, close, and place items in and out.

Therefore, how to make the backpack not only provide basic protection functions for items, but also make it easier for users to use the items inside and place items in categories, and the backpack can also be combined and separated, is an urgent need for relevant technical personnel. goal.
