[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knapsack used for hiking and picnics, for example, and more particularly to a knapsack that can be used as a rug.

[0002]

2. Description of the Related Art A knapsack is formed in a bag shape by sewing a plurality of fabrics, and the interior is a storage space. Although there are various sizes, shapes, and designs according to uses, hobbies, and tastes, the basic forms described above are the same.

For this reason, knapsacks can be used only for storing and carrying miscellaneous necessary items including, for example, rugs used at rest.

[0004] Further, since the knapsack is in the shape of a bag as described above, when small items or the like are stored, the storage position of the knapsack cannot be determined, and the knapsack cannot be easily removed.

[0005]

Therefore, in consideration of the above points, this invention can be used not only for storing articles but also as a rug, for example, and can easily take out articles. The task is to provide such a knapsack.

[0006]

Means for solving the above-mentioned problems will be described with reference to FIG. 1 of the embodiment. The structure is such that a body cloth 2 forming a storage space therein is bent. The closing means formed in the main body 2 and closing the storage space is constituted by a single sheet member forming the storage space, and the holding means 17 and 1 for holding the bent state.
It is a knapsack 1 having 7a, 17b, 20, 20a, and 20b.

[0007]

In other words, according to the above-described structure, when articles are stored as a knapsack, the sheet-shaped body cloth is appropriately bent to form a storage space inside, and the articles are stored in the storage space. Then, the folded state of the main body cloth and the closed state of the storage space are maintained using the holding means.

For example, in the case of forming a sheet for use as a rug, the holding state of the holding means may be released, the storage space may be opened, and the body cloth may be unfolded. Further, since the bending is performed by the prescribed first folding curve and the second folding curve, a constant development state is always obtained when the body cloth is developed.

As a result of the above, according to the present invention, in addition to storing and carrying articles, the article can be used, for example, as a rug, so that one article can be used in two ways, which is convenient.

In addition, another use of this knapsack is
Since the rug is a necessity for hiking and picnics, the luggage can be made compact because the rug is not required.

[0010] Further, since the folding curve is defined, a constant development state is obtained when the main body cloth is expanded, and the usability when used as a rug can be improved.

Further, since the knapsack is developed in the form of a sheet, necessary articles can be easily taken out.

[0012]

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing an expanded state of the knapsack 1. As shown in this figure, the body cloth 2 of the knapsack 1 is formed of a rectangular vinyl sheet, and a storage space is provided on the sheet surface of the vinyl sheet. Are formed, and a first holding means 7 and a second holding means 8 for holding the bent state are formed. .

That is, the above-mentioned folding curves are three folding curves 3, 4 from the first to the third which divide the longitudinal side into four equal parts.
5, and after bending at these three bending curves 3, 4, and 5,
This is one fourth folding curve 6 for bisecting the side in the other direction.

The above-mentioned body cloth 2 includes a backing string 10 and a body cloth 10 in a portion 9 (backpack portion) surrounded by the above-mentioned first fold curve 3, third fold curve 5 and fourth fold curve 6. 2 forms a part of the above-described first holding means 7 that holds the bent state in each of the above-mentioned bending curves 3, 4, 5, and 6.
The size of the above-mentioned back portion 9 is set to be suitable for carrying.

The above-described backpack string 10 allows the insertion tube 11 mounted on the edge side of the backpack portion 9 to insert and hold an intermediate portion thereof,
Two holding holes 12, both ends of which are formed on the fourth folding curve 6 side,
12, the knots 10a, 10a are formed and attached.

Note that the carrying strap 10 is integrally formed with accessory compartments 13 and 14 as shown in FIG. The accessory compartments 13 and 14 are storage units 13a, 13a and 1 according to the size of accessories to be stored, such as the writing implement 15 and the flashlight 16.
4a, and is integrally fixed to the outer surface of the backpack 10 by appropriate means such as sewing or adhesion.

A part of the first holding means 7 described above is
It comprises a closing lid 17 attached to the edge of the backpack 9 and a hook recess 17a formed on the upper surface thereof. It is formed on the lower surface of the portion 18 (surface portion) adjacent via the folding curve 6.

The above-mentioned second holding means 8 comprises a holding band 20 formed on the upper surface of a portion 19 adjacent to the carrying portion 9 via the first folding curve 3 and a hook concave portion 20a formed on the lower surface at the tip of the holding band 20. And a hook projection 20b formed on the upper surface of the portion 21 adjacent to the portion 19 via the fourth folding curve 6.

Next, the function and effect will be described. When the knapsack 1 is used, the main body 2 made of a vinyl sheet is first bent. This bending is performed at the first bending curve 3 (arrow a in FIG. 1), then at the second bending curve 4 (arrow b in FIG. 1), and further at the third bending curve 5. (Arrow c in FIG. 1). Then, it becomes a long state as shown by the imaginary line in FIG. 2, and then it is bent at the fourth bending curve 6 (arrow d in FIGS. 1 and 2). At this time, the space surrounded by each part of the main body cloth 2 divided by the folding curves 3, 4, 5, and 6 becomes the storage space 22.

In order to maintain the folded state of the main body 2 having the storage spaces 22 and the closed state of the storage spaces 22, the second holding means 8 is used.
And using the first holding means 7 as appropriate.

When used as a rug or the like, for example, when eating a lunch box, the first holding means 7 is used.
The holding state of the second holding means 8 is released and the storage space 2 is released.
2... Are released, and the folding at the folding curves 3, 4, 5, and 6 of the main body cloth 2 is released to perform the development.

As described above, since the knapsack 1 can be used as a rug in addition to storing and carrying articles, it can be conveniently used in two ways with one article.

Further, since another use of the knapsack 1 is a rug which is a necessity in hiking and picnics, the luggage can be made compact because the rug is not required.

Further, since the knapsack 1 is developed in the form of a sheet, it is possible to easily take out necessary articles even when small articles are stored.

The above is one embodiment of the present invention, and another structure may be adopted. For example, the second holding means constituted by the holding band and the hook may be constituted by the insertion cord 23 and the stopper 24 as shown in FIG. The base of the insertion string 23 is attached to the middle position of the upper part of the back part 9 and the free end holds the above-mentioned stopper 24. Then, insertion holes 25 are formed at positions corresponding to the mounting positions of the insertion cords 23.

That is, the stopper 24 is inserted into each of the insertion holes 25.
And the insertion cord 23 is inserted, and the insertion hole 25 of the surface portion 18 is inserted.
If engaged by pulling out the retaining member 24 to the opening edge of the insertion hole 25 from Ru can keep strongly hold the folded state of the body fabric 2.
