Description

Bag capable of being used as backpack and handbag

Technical Field

The utility model relates to a bag for holding articles, in particular to a bag which can be used as a backpack or a handbag.

Background

The bag for holding the articles can be divided into a backpack and a handbag according to the carrying manner, and the backpack and the handbag are both provided with a body and two belt bodies. The two belt bodies of the backpack are arranged at the rear side of the backpack body, and after the two arms of the user pass through the two belt bodies of the backpack, the backpack body can be carried on the back of the user, so the backpack is called as a backpack. The two straps of the handbag are provided on both sides of the opening at the top of the body of the handbag, and the user can lift the body of the handbag with one hand after holding the two straps of the handbag with one hand, and thus the handbag is called a handbag.

Although the user can hold the two straps of the backpack with one hand to lift the backpack body with one hand in a manner similar to the lifting of the body of a handbag, the two straps of the backpack are located at the rear side of the backpack body, so that when the user lifts the backpack body with his or her hand, the backpack body is inclined at an angle that makes it difficult for the user's hand to take items inside the backpack body.

The top of the backpack body is usually provided with a handle, and the relative positions of the backpack body and the handle are exactly positioned on the same plane in the vertical direction, so when a user holds the handle of the backpack to lift the backpack body, the backpack body can be positioned below the handle of the backpack, and the angle of the backpack body enables the user's hand to easily take articles inside the backpack body. However, the length of the carrying handle of the backpack is generally shorter than the length of the plurality of straps of the handbag, and is not suitable for being carried on the shoulder or hung on the arm.

The two bands of the handbag are positioned above the body of the handbag, so that when the user holds the two bands of the handbag by hand to lift the body of the handbag, the body of the handbag is positioned below the two bands of the handbag at an angle that allows the user's hand to easily access the contents inside the body of the handbag.

Furthermore, the two straps of the handbag are longer than the handle of the backpack, and are suitable for being carried on shoulders or hung on arms. However, the two straps of the handbag are shorter than the straps of the backpack, which is not conducive to the passage of the user's arms and there is no way for the user to carry the handbag on the back of the user.

Since the body of the handbag and the relative positions of the two bands are exactly on the same plane in the vertical direction, the weight of the handbag is concentrated on the user's hand or arm or shoulder by the bands of the handbag regardless of the user's hand lifting the handbag or hanging the handbag on the arm or carrying the handbag on the shoulder, without varying with the length of the bands of the handbag. Thus, the length of the two straps of the handbag is generally fixed, without the need for adjustment.

Since the relative positions of the backpack body and the two straps are just behind each other and are not on the same plane in the vertical direction, the backpack body is attached to the back of the user after the user's arms pass through the two straps, and the weight of the backpack is dispersed to the user's shoulders and back by the two straps and the backpack body. The different positions of the backpack body against the back of the user can affect the weight dispersion effect of the backpack. Therefore, the length of the two belt bodies of the backpack is adjustable, and a user can adjust the position of the body of the backpack, which is attached to the back of the user, by adjusting the length of the two belt bodies of the backpack, so as to provide better carrying effect.

Since the body of the handbag is easily folded, a storage bag can be integrally formed inside the handbag, and the body of the handbag and the two bands can be stored in the storage bag in a folded manner so as to reduce the volume. Since the body of the backpack is difficult to fold, the body of the backpack and the two straps cannot be folded to reduce the volume, and the inner side of a general backpack is not necessary to form a storage bag integrally.
