Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a new type of collapsible bag that can be used to store and carry OA equipment such as portable word processors and notebook computers or other articles.

[0002]

[Prior art]

 The conventional hard-type bag of this type, which is used for storing and carrying OA equipment, etc., is large in size so that the stored items can be stored tightly so as not to cause looseness and clearance. And the thing of the integral structure with a fixed shape was common.

[0003]

[Problems to be solved by the invention]

 Therefore, in the above-mentioned conventional bag, it is not possible to cope with the bag even if the size and shape are slightly different, so that it is necessary to prepare several kinds of bags, and such bags cannot be folded. It was bulky and had problems when many bags were packed and shipped.

The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to make it possible to use a hard type bag with no elasticity in a free size. The purpose of the present invention is to solve the above-mentioned conventional problems by enabling both the front and back surfaces of a bag to be freely reversible and non-bulky.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the folding bag according to the present invention is constructed by folding a single sheet body 10 which is developed in a cross shape, and folding up a front plate 1, a rear plate 2, right and left side portions 3.4, and a bottom portion. 6 and an upper lid 5 are integrally formed into a box-shaped luggage main body 20, and the front plate 1 and the rear plate 2 are integrally coupled to each other via the bottom surface portion 6 so as to face each other. The part 3.4 is formed integrally on the left and right sides of the rear face plate 2 and further has front abutment pieces 7.8 on the left and right side edges of the left and right side parts 3.4, respectively. .4 and the bottom portion 6 are integrally connected via a corner portion 9 which is folded in a triangular shape, and the inner surface of the front plate 1 and the outer surface of the front contact piece 7.8 are detachably engaged with each other. It is made. Further, a tape-shaped fastening piece made of a hook-and-loop fastener which is detachably connected to both the inner and outer surfaces of the front contact piece 7.8 connected to the left and right side portions 3.4 and the inner and outer surfaces of both right and left portions of the front plate 1. 11.12 is attached.

[0006]

Embodiment

 Hereinafter, an embodiment will be described with reference to the accompanying drawings.

As shown in FIG. 5, the sheet body 10 is formed from a cloth such as leather or synthetic leather, or a cloth or a vinyl sheet into a substantially vertically long cross shape as shown in FIG. With the long rectangular portion as the center, a vertically rectangular side surface portion 3.4 on the left and right sides, a horizontal rectangular upper lid portion 5 on the upper edge, and a uniform bottom surface portion 6 on the lower edge are integrally coupled, respectively. In addition, side part 3. A front contact piece 7.8 of substantially the same shape is integrally formed on the left and right edges of the rear cover 4, and an upper cover turning portion 15 is integrally provided on the upper cover 5. A front plate 1 of the same shape and size is integrally formed. At the corner between the side surface portion 3.4 and the bottom surface portion 6, a square corner portion 9 that is folded into a triangle is formed. The corner portion 9 is formed by folding the diagonal line 9a into a mountain or a valley.

[0008] A tape-shaped engaging piece 11 made of a hook-and-loop fastener is integrally attached to the front contact piece 7.8 so as not to peel off on both front and back surfaces of the front face, and the front plate 1 and the upper cover turning piece 15 are attached. Attachment pieces 12.13 made of the same hook-and-loop fastener are attached to both the front and back sides at both left and right ends of the above.

In FIG. 5A, the front plate 1 and the rear plate 2 are folded along a fold 1 a. 2a is folded up to the front side, and at the same time, the left and right side portions 3.4 are folded along the folds 3a. Fold each side up from 4a. At this time, when the corner portion 9 is folded up so that the diagonal line 9a becomes a mountain, the corner portion 9 is folded inward into a triangle. When the side part 3.4 is folded up, the front contact piece 7.8 is bent inward at a right angle and folded inside the front plate 1 so that the two surfaces are joined, so that the engaging pieces 11.12 are engaged and the bottom surface is joined. A box-shaped bag body 20 in which the front and rear double-sided plates 1.2 and the left and right side surface portions 3.4 are opposed to each other on four sides of the portion 6 is formed. When the upper lid part 5 is closed and the inner surface of the upper lid return part 15 is joined to the front surface of the front plate 1, the fastening pieces 13.12 attached to both sides are engaged to close the upper opening of the bag body tightly. Can be.

When the sheet body 10 is turned upside down and folded in the same manner, the back side is turned upside down, and a bag can be obtained in a so-called reversible manner.

When the bag main body 20 is folded, the fastening pieces 11.12 are peeled off to form a single sheet body 10 which is developed in a cross shape as described above, and the left and right side portions 3.4 are further placed on the back. When the front plate 1 is folded so as to overlap the surface of the face plate 2, and the front plate 1 and the upper lid portion 5 are overlapped from above, the flat plate is folded as shown in FIG. 4 and FIG. If the object to be stored in the bag is slightly larger or smaller than the bag's internal volume, the degree of engagement of the engagement pieces 11.12 when the front plate 1 is folded up and joined to the front abutment 7. It can be used by adjusting it to a free size by shifting it to the left or right.

[0012]

[Effect of the invention]

 Since the present invention is configured as described above, a single cross-shaped sheet body is folded up, and the bag is attached by joining the joining portion with a tape-like attaching piece made of a hook-and-loop fastener. It can be easily assembled or disassembled with one touch, folded flat and thin, or both sides can be used reversibly, and the size and volume of the bag can be made free size by adjusting the joining position of the engaging piece. It can be used, has a simple configuration, and can be provided at low cost.
