At this time, the bag body 100 is selectively opened and closed to form an accommodation space in which items are accommodated, and refers to the main body of a general backpack.

However, the bag body 100 according to the present invention is formed so that the bottom portion 110 forming the bottom surface of the bag body 100 can be opened. The side is fastened by the bag body 100 and the bottom zipper 120, and is opened and closed by the bottom zipper 120.

Accordingly, when the bottom zipper 120 is opened, as shown in FIG. 4, the bottom portion 110 is unfolded while the rear edge is connected to open the lower side of the bag body 100.

On the other hand, the shoulder strap 200, as shown in Figure 3, is provided in a pair on both sides of the back of the bag body 100.

At this time, each of the shoulder muscles 200 is fitted on both arms of the user, so that the bag body 100 is seated on the user's shoulder.

Looking at the specific shape of the shoulder strap 200, the upper portion of the shoulder strap 200 is fixed to the upper portion of the bag body 100 and the inside is formed of an elastic material so that the load is distributed and supported by being in close contact with the user's body. It is configured to include a shoulder support 210 and a chest support 220.

In this case, the shoulder support part 210 and the chest support part 220 are divided according to the body part of the user to which they are in close contact, and as shown in FIG. 3, the inclined direction may be formed in different directions.

A coupling band 230 extending from the chest support part 220 to a predetermined length is coupled to a lower portion of the chest support part 220.

The coupling band 230 is preferably formed of a narrow fabric material, and is provided with a length adjustment device 231 for adjusting the length of the connection on one side.

At this time, the length adjustment device 231 may be applied to a leather lock used in a conventional bag strap.

In addition, a fixing band 239 formed of a fabric material band of a predetermined length is fixed to the lower side of the bag body 100, and an arm for coupling the male buckle 235 and the buckle at the end of the fixing band 239 Buckle 237 is connected.

The female/male buckles 237 and 235 may be male and female portions of a two-touch buckle or a one-touch buckle used in a bag.

Accordingly, when the left coupling band and the left fixing band are buckled, and the right coupling band and the right fixing band are buckled, a '11' shaped shoulder strap is formed.

However, when the left coupling band and the right fixing band are buckled, and the right coupling band and the left fixing band are buckled, the shoulder straps form an intersecting shape in the form of'x'.

Accordingly, when the shoulder straps are crossed in the form of'×', when the length adjustment tool 231 is pulled, the bag body is stretched in the diagonal direction of'×' so that it can be completely tightly fixed to the user's back.

Therefore, in the present invention, the shoulder strap is usually arranged in the form of an '11' shape, so that it is used in a state of good usability so that it is easy to tie or take off the bag, and then when running or mobility is required (when close contact of the backpack is required), Shoulder straps can be cross-linked in the shape of an'x' to improve adhesion.

On the other hand, although not shown, a plurality of the fixing bands 239 are provided with a height spaced apart from each other, so that the user can adjust the lower coupling position of the shoulder strap 200 to the bag body 100 according to the physical characteristics and use environment.
