Description

[Detailed Description of the Invention] The present invention relates to the structure of a foldable bag.

Small shoulder bags, especially bags for men called men's bags, are usually thin and often foldable to increase storage capacity when needed.

It is important for this type of product to have a sleek appearance.
If it becomes too thick or the folded part opens sloppily, its commercial value will be lost.

However, since this type of bag is made of leather or synthetic leather, it is difficult to keep it folded all the time.

To solve this problem, for example, (1) iron the crease to create a curl (2) sew some of the crease together (
3) High-frequency processing is applied to the folds to create streaks to make them easier to fold. (4) Many products are equipped with belts on the side of the bag to prevent them from opening, but these methods have little effect or affect the appearance. The disadvantage was that the smartness, which is a necessary condition, was lost.

As a bag of the type (4) above, the bags shown in FIGS. 1 and 2 are known.

In both figures, 1 is a presser belt, 2 is a caulking stud, and 3 is a hook.The caulking studs wrap the presser belt around the bag body to prevent the bag from opening.

However, when the bag is held in a folded state, the movable bottom plate 4 is flipped upward and does not function as a support plate for supporting stored items.

However, since the bag body is made of a relatively thin material for the purpose of reducing weight, the bottom wall of the bag may be deformed or damaged when the stored items are heavy.

The purpose of the present invention is to solve these shortcomings in the internal structure and provide a bag that maintains its closed state without losing its sleek appearance and is also easy to fold.

In order to achieve this purpose, the present invention includes a bottom plate comprising a connecting part connected to one inner wall of the bag, a bottom plate part bendably integrated with the connecting part, and a bottom plate of the bottom plate. The bag includes a first locking member provided on the back surface of the bag, and a second locking member that is provided on at least the other inner wall of the bag and is connectable to the first locking member.

When increasing the storage capacity of the bag, the connecting part covers the bottom wall of the bag, and the bottom plate part is bent almost at right angles to the connecting part and placed along the other inner wall.
and the second locking member are connected to each other, while when increasing the storage volume, the first and second locking members are disconnected and the top of the bottom wall is covered by both the connecting part and the bottom plate part. That's what I did.

In this way, when the storage volume of the bag is reduced, the state is maintained by the first and second locking members, and when the storage volume is increased, the bottom plate and the connecting part cover the bottom wall. , the bottom wall will not be damaged.

Embodiments of the present invention will be described below with reference to the drawings.

This bag has two storage volumes that can be switched.

In FIG. 3, the bottom plate 10 includes a bottom plate part 12 having a size that covers the entire bottom surface of the bag, and a play part (connection part) a connected thereto, and is fixed to the back side of the inner wall of the bag 11. Flip up the part 12 (bottom plate part 1
2 at a substantially right angle to the connecting portion a).

The pile side 14 of the hook-and-loop fastener is attached to the front side of the inner wall of the bag, while the hook side 15 is attached to the back side of the bottom plate part 12.

A pile side 17 is also attached to the bottom wall 16 of the bag 11.

13 is a lock. FIG. 3 shows the bag 11 in a swollen state with stored items, and shows the bottom plate part 12 and the connecting part a.
The bag covers the top of the bottom wall 16, but by changing the fixing positions of the hook side 15 and the pile side 17, the size of the bag can be made to correspond to the size of the stored items.

At this time, since the pile side 15 and the hook side 17 are arranged closer to the bottom wall 16, the front and rear walls will not expand even if heavy objects are placed therein.

FIG. 4 shows the bag 11 in a folded state. The bottom plate 12 is flipped upward, and the thickness of the bag is determined by the connecting part a, and the hook side 15 and the pile side 14 are fastened together to prevent the bag from folding. Prevented from spreading.

In this state, the connecting portion a covers the top of the bottom wall 16 and acts as a bottom plate, so no force is applied to the bottom of the bag and deformation is prevented.

FIG. 5 shows an embodiment in which a hook 19 is used instead of a hook-and-loop fastener.

As described above, according to the present invention, the folded state can be maintained by improving the internal structure, so the appearance is not affected and there are no restrictions on the design.
