Description

The present invention has a structure equipped with belts for supporting and lifting the contents in good balance on both sides of the front body and the back body which are connected to the bottom when the rucksack is carried on the back. The rucksack is designed so that the contents can be easily put in and taken out with one hand because the mouth closes appropriately depending on the amount and weight of the rucksack, so that the contents are not exposed even if a fastener such as a fastener is not installed in the mouth. be.

A rucksack supports stored items on the shoulders and back, and is therefore less tiring than shoulder bags and handbags, and is convenient for carrying heavy items such as books, documents, and water bottles. Another advantage of a rucksack is that once you carry it on your back, both hands are free.

However, due to the shape of the rucksack, the shoulder straps are connected only to the back body, and the weight of the contents is mainly applied to the connection between the back body and the shoulder straps. If you carry it on your back with it open, the mouth will open on the front torso side. In order to close the open mouth, it is necessary to install a fastener or a string to tighten the mouth, or to pull the entire surface of the front torso up and connect it to the connecting part of the back torso and shoulder straps.

The problem is that it takes a lot of time and effort to open and close the rucksack with one hand, such as opening and closing the zipper and tying it with a string. If you want to open and close the rucksack with one hand to take in and out items, such as when one hand is paralyzed or injured, or you cannot let go of the hand held by the infant, or you cannot let go of the item you are holding to avoid danger. It will take time and effort.

The problem to be solved is the structure of the rucksack, which, depending on the contents, opens to the front body side depending on the contents when the contents are put in and carried on the back unless a fastener or a string for tightening is installed in the mouth. To provide a rucksack having a structure in which the mouth does not open to the front body side when carrying a stored item.

The main feature of the present invention is a rucksack structure in which a belt for supporting balance is arranged between a bag portion and shoulder straps of the rucksack. A belt to support balance refers to a belt that connects both ends to the front body and back body of the bag, with a device such as a square hook that changes the fulcrum by sliding. Connect one end of the shoulder strap.

The rucksack of the present invention has a structure in which the front body and the back body connected to the bottom support and lift the stored items in a balanced manner regardless of the size, amount, or weight of the stored items when carried on the back, and the mouth always faces the sky. Since the mouth closes appropriately, there is no need to install a fastener or string to tighten it, and parts with a lid function can be placed on the mouth with only simple fasteners such as hooks and magnets, so the mouth can be opened with only one hand. It can be opened and closed, and contents can be put in and taken out with only one hand.

1 is a front perspective view of an example of a rucksack of the present invention, to which belts are attached for supporting and lifting a stored item with a front body and a back body connected to the bottom; FIG.

Next, embodiments of the present invention will be described with reference to the drawings.

When the backpack (1) of the present invention is carried on the back, the tool (6) such as a square can flexibly moves in response to the vector of the size, amount, and weight of the contents, and by changing the fulcrum, it faces the sky. At the same time as the orientation of the mouth of the rucksack (1) is maintained, the belt (5) and the connecting parts of the front body (2) and the back body (3) are forced to approach each other. closes properly.
