The outer material and the lining can be made of, for example, one of casual materials such as canvas or denim, the other as chic fabric, or the other having waterproof or water repellent properties. Further, one may be made of cloth and the other may be made of leather or synthetic leather.

The cylindrical portion 1 is assembled as follows: a bottom portion 5 (see FIG. 3), a front portion 6 and a rear portion 7 rising from the front and rear of the bottom portion, and a top portion corresponding to both ends of the sheet. 8 and 9. The side members 2 and 3 are sewn to the left and right ends of the bottom 5 and stand up. Bottom 5
In addition, it is preferable that the top surfaces 8 and 9 have a certain rigidity and strength by sandwiching a hard sheet such as plywood, a synthetic resin sheet or cardboard between the outer material and the lining. Of course, the front part 6 and the rear part 7 can be similarly made rigid. That is, the cylindrical portion 1 may have rigidity as a whole as long as at least the bent portion has reversible flexibility.

As shown in FIGS. 3 and 4, well-known bottom studs 10 are attached to the four corners of the upper and lower surfaces of the bottom portion 5, respectively. In addition, linear fasteners 11 and 12 are sewn along the edges on the inner surface of the front surface portion 8 on the front side and the outer surface of the top surface portion 9 on the rear surface side, respectively. The hook-and-loop fasteners 11 and 12 are for firmly closing the top faces 8 and 9 as shown in FIG. However, when the overlapping margin between the top surfaces 8 and 9 is large, it is not necessary to provide them.
Alternatively, the two members may be connected to each other with a detachable slide fastener or other openable and closable connecting means such as buttons and metal fittings.

As shown in FIG.
The left and right two reinforcement belts 13 are sewn on the outer surface of the rear surface portion and the outer surface of the rear surface portion 9 to the top surface portion 9 so as to extend vertically, respectively. The bases of a pair of hands 14 (which can be hung on the shoulder in some cases) to be sewn are sewn. Further, a pocket (or a small bag body) 15 is attached to the front portion 6, and the pocket 15 is a known one having a gore portion 17 which is opened and closed by a slide fastener 16 from the side surface to the upper surface. The slide fastener 16 may be provided so as to surround the entire circumference of the gore portion 17, and the pocket portion 15 may be detachable.

The half body 18a of the slide fastener is sewn so that a band-shaped cloth supporting the row of teeth (mussels) is sandwiched between the outer material and the lining. The other half 19a of the slide fastener 19 is also attached to both side edges of the rear surface portion 8 and the top surface portion 9 continuous therewith.

In the embodiment shown in FIG. 1, the side members 2, 3
Are rectangles corresponding to the left and right openings of the tubular portion 1 sewn with cloth, respectively, and bags 4 and 4 are integrally provided on the outer surface thereof. The bag body 4 is an outer surface portion 2 which is on the outside in the state of FIG.
And a gore portion 21 connecting the outer surface portion 20 and the inner side surface members 2 and 3. The gore portion 21 includes a bottom surface 23, a front surface 24, a rear surface 25, and a top surface 26. Outer portions of the outer surface portion 20 and the gore portion 21 are made of the same fabric as the surface material of the tubular portion 1, and portions of the side members 2, 3 and the gore portion 21 that come out when turned over are the same fabric as the lining material. And

On the other hand, a reinforcing belt 27 extending vertically is sewn to the center of the outer surface portion 20 and the side members 2 and 3, respectively, and a belt mounting member 29 is mounted near the upper portion thereof. In the embodiment shown in FIG.
, A known shoulder belt 30 is detachably attached.

Between the gore portion 21 and the outer surface portion 20 and the gore portion 2
Between the lower part of the front surface 24, the top surface 26, and the lower part of the rear surface 25, between the vicinity of the lower part of the front surface 24 and the lower part of the rear surface 25, each of the first and side members 2 and 3 can be freely opened and closed by a facing slide fastener extending in an inverted U shape. 1 opening 32 and 2nd opening 3
3 are provided. The first opening 32 and the second opening 33 are, as indicated by imaginary lines P1 and P2, respectively,
It may be extended to reach the bottom surface 23.

Also, adjacent to the outside of the second opening 33,

8b is attached. Also, the top surface 26 is located at substantially the same position as the slide fastener half 18b.
A part of the slide fastener half 19b that meshes with the slide fastener half 19a on the side edge on the rear surface part 7 side of the tubular part 1 is attached from the middle of the rear surface 25 to the lower end of the rear surface 25. In addition, in the top surface part 26, both the halves 18b, 19b
Are overlapped with each other, but a half 19b corresponding to the rear top surface 9 of the top surfaces 8, 9 of the cylindrical body 1 overlapping each other is shifted inward.

Further, the front part 6 and the rear part 7 of the cylindrical part 1
A root portion of a reinforcing support belt 34 is sewn underneath, and the tip of the support belt 34 is detachably attached below the gore portions of the bags 2 and 3 with a button 35 or the like. The slider of each slide fastener employs the same reversible jumper as a slider such as a reversible jumper.

The bag A constructed as described above is shown in FIG.
Alternatively, as shown in FIG.
In this case, it can be used with the front and rear hand 14 or by hanging it on the shoulder with the shoulder belt 30. In this case, all of the internal cavities of the tubular portion 1 can accommodate the objects, and the left and right bags 4 can also accommodate the objects. As shown in FIG. 1, in order to take in and out the contents in the tubular portion 1, as shown in FIG. Fasteners 18a, 18b and 19
a, 19b are opened slightly, and the top surfaces 8, 9 of the tubular portion 1 are opened. The bags 2 and 3 can be opened and closed with a slide fastener of the first opening 32.

After the top surface 8 of the cylindrical portion 1 is opened, it can be taken in and out through the second opening 33. On the other hand,
As shown by the imaginary line P2 in FIG. 1, when the slide fastener of the second opening 33 is provided so as to reach the lower ends of the front surface and the rear surface of the gore portion 21, the side members 2 and 3 are folded inward to make the cylinder. The shape-like portion 1 and the inside of the bag body 4 can be widely communicated to obtain an integrated, horizontally long storage portion. In that case, there is an advantage that a particularly long object can be accommodated. In that case, a long thing may be taken in and out of the first opening 32.

When the bag A in the state shown in FIG. 2 is turned over, first, the shoulder belt 30 is removed, and the top surface portion 8 of the tubular portion 1,
9 (see FIG. 1), and then open all four slide fasteners 18 and 19 for connecting left, right, front and rear, and extend flat as shown in FIG. Next, as shown in FIG. 4, the whole is turned over, the side members 2, 3 and the bags 4, 4 are raised as shown by arrows, and the sliders of the slide fasteners 18, 19 for connection are pulled up (see FIG. 5). ). As a result, a second use mode in which the bags 4, 4 enter the inside of the tubular portion 1, the lining of the original tubular portion 1 is on the outside, and the side members 2, 3 are on the outside is obtained. In this state shoulder belt 3
0 is attached to the side members 2 and 3. In the present embodiment, the hand is not used in the upside down state, but may be attached. In the course of the above-described turning operation, it is necessary to once take out the contents in the tubular portion 1, but the contents in the bags 4, 4 may be left as they are.

In the second use state shown in FIG.
The left and right dimensions are shorter than the first use state by twice the thickness of the bags 4, 4 and are easy to carry. However, cylindrical part 1
Is reduced by that amount. Although the top surfaces 8 and 9 of the cylindrical portion 1 are superposed upside down, they can be securely closed by the hook-and-loop fasteners 11 and 12 as in the first use state. Further, in a portion where both the halves 18b and 19b of the top surface portion 26 of the bag body 4 are overlapped with each other and are doubled, the left and right bag bodies 4 are inverted, so that the front top surface 8 on the lower side comes to the lower side. Since the corresponding half 18b is shifted inward, there is no problem in the connection between the top surfaces 8, 9 of the tubular portion 1 and the bag 4.

The loading and unloading of the contents in the cylindrical portion 1 is performed in the same manner as in the first use state, as in the case of the first use state.
9 can be opened and closed. The contents of the bags 4 can be taken in and out by opening and closing the second opening 33. However, the first
It is also possible to take in and out from the inside of the cylindrical portion 1 by using the opening 32 of. Also, in this use state, as shown by the imaginary line P2, when the slide fastener of the first opening 33 is provided so as to reach the lower end of the side surface of the gore portion, the outer surface portion 20 is folded down inside to form the cylindrical portion. It is possible to obtain a large storage unit in which the bag 1 and the bag 4 are integrated.

The bag B shown in FIG. 6 and FIG.
Is an embodiment in which is the gore of a bag. That is, this is a side member 43, 44 in which the bag body 42 is integrated with the front edge and the rear edge of the bottom of the cylindrical portion 41, respectively.
Is sewn at the lower end and the other peripheral portions are connected to be openable and closable by slide fasteners 45 and 46. The basic configuration and operation are the same as those of bag A in FIG. Note that a pair of hanging hands 47 are attached to the bags 42, 42. 6 is wider in the state of FIG. 6 in which the bag body 42 is extended outside, and the entire inside of the cylindrical portion 41 can be used as a storage space, and in the state of FIG. , Convenient to carry.

In this bag B, the hand 49 is made to appear on the top surface 48 in a state where the bag is turned upside down.
The opening and closing of the bag body 42 is performed by an opening 50 formed in the upper part of the side member 42 of the bag body in a laterally linear shape.
In this embodiment, since the width of the tubular portion 41 is almost the same as that of the two bags 42, no object can be put in the tubular portion 41 in the inverted state. However, needless to say, the width of the cylindrical portion 41 may be further increased so that an object can be accommodated in the cylindrical portion 41 even when it is turned over.

The bag C shown in FIG. 8, Reversi the present invention
It is another embodiment of the bull bag , and the bag is omitted . This simply connects the adjacent side edges 61 and 62 of the sheet 60 in the unfolded state with a slide fastener so as to be detachable.
