Abstract

(57) [Summary] [Purpose] According to the amount of a stored item, the opening of the storage unit is appropriately adjusted from the fully opened state to the fully closed state without changing the left and right width of the storage unit, and the stored items in the storage unit are adjusted. Eliminate play and move the center of gravity closer to the back so that you can carry it on your back naturally. [Structure] A box-shaped bag body having an opening at the top of the storage part has a backpack band on the back side and covers the opening of the storage part from the rear side upper edge to the front side, In a backpack bag in which the locking tool has a lid part that can be engaged with and disengaged from the locking receiving tool on the front part of the bag body, the left and right side surfaces of the bag body are foldable gussets, and the inner lid is on the rear side of the opening of the housing part. And a locking portion of the inner lid is formed to be engageable with and disengageable from a locking receiving portion on the front upper part of the bag body so that the accommodation opening can be opened by the inner lid without changing the left and right opening widths. It can be opened and closed from the fully open state to the fully closed state.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a backpack bag used as a storage case for commuting to school or for other purposes.

[0002]

[Prior Art]

 For example, the school bag used for commuting to school has a backpack band on the back side of the main body of the bag that has an open upper part of the accommodation part, covers the opening of the accommodation part from the upper edge on the back surface side, and reaches the front side. The locking device at the edge is configured to have a lid that can be engaged and disengaged with the locking receiver on the front part of the school bag body, and the lid opens and closes the storage unit.

By the way, since the opening of the accommodating portion is completely opened and covered by the lid portion, there is the following inconvenience.

[0004] When the number of contained items is small, the contained items move and play in the accommodation unit, and this is particularly noticeable for elementary school children because the activity is active. As a result, it is difficult to carry on the back, the contents are damaged, and the center of gravity of the contents easily moves away from the back, so that there is a drawback that it is pulled backward and becomes heavy, which increases physical stress.

[0005]

[Problems to be solved by the device]

 The problem to be solved is that it is not possible to appropriately adjust the opening of the storage unit from the fully open state to the fully closed state according to the amount of the stored items without changing the left and right opening widths of the storage unit.

[0006]

[Means for Solving the Problems]

 The measures taken to solve the above-mentioned problems include a backpack band on the back side of the box-shaped bag main body with an open upper part of the storage part, and a front side covering the opening of the storage part from the upper edge on the back side. In the backpack bag that reaches the side, the lower edge locking device has a lid part that can be engaged and disengaged with the locking receiving device on the front part of the bag body, and the left and right side surfaces of the bag body are foldable gusset parts, In addition, an inner lid portion is arranged on the rear side of the opening of the accommodating portion, and a locking portion of the inner lid portion is detachably formed on a lock receiving portion on the front upper part of the bag body. The feature is that the opening can be opened and closed from the fully open state to the fully closed state without changing the left and right opening widths.

[0007]

[Action]

 After opening the lid part and the inner lid part and putting the contents in the fully opened storage part, the opening of the storage part is closed by the inner lid part to the fully open state or the fully closed state until the storage items cannot move.

As a result, the opening of the accommodation portion of the box-shaped bag body is changed in a state in which the left and right opening widths do not change and the front and rear opening widths change from the fully open width to the fully closed width of the gore. Therefore, even if the amount of the contained items changes and the center of gravity approaches the back side in the accommodating portion, and the center of gravity approaches the back side, it is possible to always adjust the accommodation state so that it is easy to carry.

[0009]

【Example】

 The backpack bag illustrated in the drawings is of a school bag type, and the bag body 1 is in the shape of a vertically long flat box, and the upper portion of the accommodation portion 2 is open. On the back side of the bag body 1, a pair of left and right shoulder straps 4 are arranged from the upper edge on the back side to the lower side, and the lid section 5 opens from the upper edge on the back side to the opening 3 of the housing section 1. A locking tool 6 that covers the front surface of the bag body 1 and extends to the front side and is detachably attached to a locking receiving tool 7 on the front surface of the bag body 1.

The bag body 1 is formed with a foldable gusset portion 8 on its left and right side surfaces, and an inner lid portion 9 is provided on the rear side of the opening 3 of the housing portion 2. The inner lid portion 9 has a locking portion 10 which is detachably engageable with a locking receiving portion 11 on the front upper portion of the bag body 1. The inner lid portion 9 allows the opening 3 of the accommodating portion 2 to be fully opened. It can be opened and closed until it is closed.

The inner lid portion 9 is formed in such a form as to cover the accommodation portion opening 3 in the fully opened state.

The locking portion 10 and the locking receiving portion 11 are, for example, detachable velvet fasteners, and the locking portion 10 is formed in a band shape along the tip edge of the inner lid portion 9. Vertically long strips are formed in the left and right portions of the front upper portion of the bag body 1, and the locking portion 10 is engaged with and disengaged from the upper and lower sides of the locking receiving portion 11 so that the inner lid portion 9 holds the housing portion 2. The opening 3 can be appropriately adjusted to be closed from the fully closed state to the fully opened state with the widths of the left and right openings of the housing portion unchanged.

Therefore, in the case where the amount of contents is normal as shown in FIG. 2, the locking part 10 of the inner lid part 9 is locked in the middle part of the locking receiving part 11, and When the quantity of the object is too small as shown in FIG. 3, the locking portion 10 of the inner lid portion 9 is locked to the lower portion of the lock receiving portion 11, and the amount of the contained material is changed as shown in FIG. If there are many, as shown in the figure, lock the locking part 10 of the inner lid part 9 to the upper part of the locking receiving part 11 and store each of the contents so as not to play in the storage part 2. Can be done.

[0014]

[Effect of the device]

 A. Depending on the amount of the stored items, the opening of the storage unit can be appropriately adjusted from the fully open state to the fully closed state by the inner lid without changing the left and right opening width of the storage unit.

B. Since the contained items do not move in the accommodation section and the center of gravity approaches the back side, even if the amount of the contained items changes, it is possible to ensure a state of accommodation that makes it easy to carry on the back and prevents damage to the contained items. It is also possible to do so, and in particular, it has the characteristic that it can carry an unnatural physical burden and that it can be carried naturally with a comfortable posture.
