2. Description of the Related Art For example, a square basket used for revetment work or residential land development work is generally formed in a rectangular parallelepiped shape by a diamond-shaped wire mesh, and is installed at a site in a state where the inside is filled with debris. For installation, the above baskets are transported to the site in a folded state, then unfolded and assembled into the required shape.To make the transportation and unfolding work as simple as possible, the baskets with various structures have been used. Is considered.

For example, as shown in FIG. 6, six panel members 20a to 20f corresponding to six surfaces of a square basket are separately formed, and they are transported to the site and connected in a rectangular parallelepiped shape. As shown in FIG. 7, one trunk net panel member 30 in which a quadrangular trunk portion of a square basket is developed, and two lids attached to the opening of the trunk net. Prepare the mesh panel members 30e and 32f,
These are assembled on site, or as shown in FIG. 8, the trunk net panel member 30 and the lid net panel member 3
0e and 30f are connected in advance to form a single panel member, which is transported to the site in a folded state, which is developed at the site and assembled into a required shape (actually disclosed in Japanese Unexamined Utility Model Publication No.
No. 89033).

[0004] All of these conventional baskets are formed in an expanded form, transported to the site in a folded state, and then assembled on the site. For this reason, the folding work and the unfolding work take time and effort, and the working efficiency cannot be said to be very good. In addition, in the apparatus shown in FIGS. 6 and 8, the trunk net cannot be folded smaller than the bottom network, so that there is a problem of taking up space for transportation and storage, and the one shown in FIG. Although it can be folded smaller than the former two, the smaller it is folded, the more complicated it becomes due to the entanglement of the column lines and the like.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment of a basket according to the present invention. And two short side nets 2, 2 that close the short side faces at both ends in the axial direction.

The trunk net 1 is composed of a rectangular bottom net 3, a top net 4, and a pair of long side nets 5A and 5B. Each of these nets divides one rhombus metal net. The upper end 4a of the upper surface net 4 and the upper side 5a of the one long side net 5A are connected to each other by a frame line 7a attached to the upper side 5a. , And are formed so as to form a rectangular cylinder that is long in the axial direction.

[0014] Two opposing long side nets 5 of the trunk net 1
A and 5B are provided on the four sides around the frames 7a to 7
By attaching 7d, it is formed so as to be able to hold a fixed rectangle, whereas the bottom net 3 and the top net 4 are attached to the side edges 3b, 4b facing the short side of the trunk net 1 as described above. The frame net 1 is formed so as to be able to be telescopically folded with a folding width h equal to or less than the width H of the long side nets 5A, 5B without a frame line for shape retention being attached. As shown in FIG. 4, the bottom net 3 and the top net 4 are folded so that they can be packed in a state sandwiched between both long side nets 5A and 5B.

It is preferable that at least one bone line 8 for enhancing shape retention is provided between the upper and lower frame lines 7a, 7b at an appropriate position in the middle of the long side nets 5A, 5B. .

Further, the sides 3 of the bottom net 3 and the top net 4
As shown in FIG. 2, the end of each column line 10 is bent at b and 4b to form a frame line insertion tube 11. The tube 11 is provided with a flexible string 13 in order to prevent the line from entering and exiting when the trunk net 1 is folded or unfolded.
Can be inserted. The string 13 may be made of any material as long as it has the necessary flexibility. For example, the string 13 may be made of fiber, synthetic resin, or metal.

Further, the method of folding the bottom net 3 and the top net 4 small is optional. For example, as shown in FIG. It is possible to use a simple folding method, such as a method in which each column line 10 is laterally moved in a wire mesh plane and sequentially stacked.

On the other hand, the short side nets 2, 2 are formed so as to maintain a fixed rectangular shape by attaching frame lines 15a to 15d around a panel made of a rhombic wire net. As shown in FIG. 3, the short side nets 2 and 2 have frame lines 15a and 15b on the upper and lower sides thereof between the ends of the column lines 10 and 10 on the side edges 3b and 4b of the bottom net 3 and the upper net 4. The upper and lower sides are connected to the bottom net 3 and the top net 4 by sandwiching and inserting the connecting bone lines 16 into the tubes 11 at the end of each row line. On the other hand, the left and right sides of the short side nets 2 and 2 are connected to the side lines of the long side nets 5A and 5B by their frame lines 15c and 15d.
And 7c, 7d are connected to each other by an appropriate connection fitting such as a screw stopper.

In connecting the short side nets 2 and 2 to the bottom net 3 and the top net 4, when the bone line 16 is inserted through the tube 11, the string 13 inserted through the tube 11 is removed. However, it is not always necessary to remove the string 13 when the string 13 has a small diameter and does not particularly interfere.

As shown in FIG. 4, the basket having the above-mentioned structure is composed of a trunk net 1, a bottom net 3 and an upper net 4, and a long side net 5.
A and 5B are sandwiched between the left and right long side nets 5A and 5B by being telescopically folded at a folding width h that is not more than the width H of the width A and 5B.
The short side nets 2 and 2 are superposed on the outer side of the long side nets 5A and 5B and packed. Then, after transporting it to the site, the short side nets 2 and 2 are removed and the left and right long side nets 5 are removed.
A and 5B are developed into a rectangular tube by pulling them apart,
The front and rear short side nets 2 and 2 are attached by the above-described method, and are installed in a state where the inside is filled with a filler such as debris.

Before the upper side of the short side nets 2 and 2 is connected to the side 4b of the upper side net 4, the earth and stones are filled.
The upper side net 4 is closed after filling the debris with the tip side 4a separated from the long side nets 5A and 5B, and the top side 4a and the side 4b are connected to the long side nets 5A and 5B.
5B and the short side nets 2, 2. Alternatively, without opening the entire upper surface net 4, the engagement of some of the column lines of the upper surface net 4 is partially released in advance, and the short side nets 2, 2 are removed.
After completely attaching the part, open that part and stuff it with stone,
After that, the open portion may be closed.

Thus, the above basket is very convenient because it can be folded into the width H of the long side nets 5A and 5B and transported to the site because it does not take up space for transportation and storage 11. . In addition, when deployed on site, since the left and right long side nets 5A and 5B can be deployed in a rectangular cylindrical shape simply by pulling them apart from each other, the deployment work is very easy, and the ingress and egress and entanglement of the row lines, etc. Does not occur.

FIG. 5 shows a second embodiment of the basket according to the present invention. In this basket, one of the two short side nets 2, 2 has a long side net 5A, 5B is different from the first embodiment in that it is rotatably connected to the side of 5B. In this case, in the illustrated example, the two short side nets 2, 2 are connected to different long side nets 5A, 5B, but it goes without saying that they may be connected to the same long side net 5A or 5B. It is.

In each of the above embodiments, as a method of attaching the short side nets 2 and 2 to the short side of the trunk net 1, the frame lines 15 a and 15 b of the short side nets 2 and 2 are attached to the bottom net 3 and the top net 4. Are inserted between the ends of the row lines 10 and 10, and the connecting bone lines 16 are inserted into the tubes 11 at the end of each row line. However, the present invention is not limited to such a method, and is well known. Various connection methods can be adopted.

The trunk net 1 is formed by bending a single rhombus wire net, but has two long side nets 5A and 5B having shape retention and a bottom net 3 which can be telescopically folded. And the upper surface net 4 may be formed separately and connected by frame lines 7a and 7b sequentially, or only the upper surface net 4 may be formed separately and connected to other parts. You may do it. As described above, when a part of the surface net constituting the trunk net is individually formed, wire nets having different wire diameters, mesh sizes, mesh shapes, and the like can be used.

Further, when the bottom net 3 and the top net 4 are individually formed, at least one of the nets is formed by the long side nets 5A and 5A without forming them with one metal net.
It is also possible to form a plurality of small-width net members having the same width as or less than 5B in a foldable manner. In this case, each mesh member may have a frame line attached to its periphery to maintain self-retaining property.

[0027]

As described in detail above, according to the present invention,
Since the basket can be folded to the width of the long side net and transported to the site, it is very convenient because it does not take up space for transportation and storage. In addition, when deploying a folded basket in the field, it can be deployed in a rectangular cylindrical shape simply by pulling the left and right long side nets apart from each other, making the deployment work very easy, There is no entanglement.
