Description

[Detailed description of the invention] Industrial field of application This invention relates to a futon basket body net using a diamond-shaped wire mesh.

BACKGROUND OF THE INVENTION The body mesh of a futon basket is usually a diamond-shaped wire mesh formed by bending rows of iron wire in a zigzag shape and connecting them to each other at the bent portions. Therefore, such a trunk net is folded into a small size by shortening the interval between each row line, and then transported to the site, expanded at the site, and then the middle rings are inserted at appropriate intervals according to the length of the net. The method used is to feed the stone into a net with a rectangular cross section, and then fill it with stones.

By the way, since the diamond-shaped wire mesh that forms the shell mesh is made up of interconnected row lines bent in a zigzag manner, the intervals between each row line tend to become smaller, so that it is difficult to insert filling stones. During work, some active measures are required to maintain the shell net in a predetermined three-dimensional shape. A middle ring is one solution for this purpose, but the work of feeding the middle ring is not only troublesome and time-consuming, but also the middle ring cannot be installed in the middle of the body net. It is unavoidable that the end face loses its shape, and if you try to attach the middle ring to this part, you will be forced to do the even more troublesome work of attaching the middle ring to the end of each row line. That was the current situation.

As a means to solve this situation, curls 1 are added to the ends of the row lines 1, 1, .
a, 1a... are formed, and this curl 1a, 1
Insert frame lines 2, 2... into a..., and connect frame line 2 and lid net 3.
and the surrounding frame 3a are tied together via coils 4, 4...
A technique has been proposed to prevent the shell net from deforming (Fig. 3, Japanese Patent Application Laid-Open No. 56-28915). However, in this case, the frame line 2 is independent for each side forming the periphery of the shell net, and is discontinuous with each other at the ridgeline of the shell net, so unless the lid net 3 is attached, It is not possible to prevent the net from losing its shape due to shrinkage of the end surface of the net, and the peripheral frame 3a of the lid net 3 does not perform its shape-retaining function until after the lid net 3 is attached. Therefore, this device could hardly contribute to the most important function of properly maintaining the shape of the shell net during the filling work.

It should be noted that there is also a known technique of providing an opening for loading stones on one side of the shell net (for example,
No. 89119), this product has a long opening, which inevitably has the disadvantage that the work of stitching the opening after filling with stones is extremely complicated.

Purpose of the invention Therefore, in view of the actual state of the prior art, the purpose of this invention is to install the lid net on the premise that the filling stones will be introduced from the end face where the lid net is attached, without providing any special openings. To effectively prevent deformation due to shrinkage of the end face of a shell net during the previous filling work, maintain the shape of the shell net in a predetermined open state, and smoothly perform the filling work. Our objective is to provide a body net for futon baskets that allows for

Structure of the invention The structure of this invention to achieve the above object is that the bone wire is inserted into the ridge line of the trunk mesh made of diamond-shaped wire mesh by sewing through the bent part of the row lines forming the trunk mesh. A curl is formed at the end of each row line on the edge of the end surface, and an independent outer frame line is inserted into the curl on each of the four sides of the body mesh, and both ends of the outer frame line are wrapped around the bone line and locked. The gist of this is to regulate the dimensions of each side of the end surface of the shell net.

Effect When based on the configuration of this device, each outer frame line is
Both ends of each are fixed to the bone line, so in conjunction with the bone line, the length of each side of the four sides of the trunk mesh is kept constant, and the shape of the trunk mesh is effectively prevented when the end surface of the trunk mesh shrinks. can be prevented. In addition, since the outer frame line and the bone line are pre-assembled to the shell netting, assembly of the shell netting on site is easy.
The minimum necessary amount is sufficient.

Example Examples will be described below with reference to the drawings.

The futon basket is formed by attaching lid nets 20, 20 to both end surfaces of a body net 10 having a rectangular cross section (first
figure).

The lid net 20 has zigzag row lines 21, 21...
A rectangular peripheral frame 22 is attached around a diamond-shaped wire mesh, the size of which is adapted to the size of the end opening of the body mesh 10.

The body mesh 10 is made by bending a diamond-shaped wire mesh consisting of row lines 11, 11... into a rectangular tube shape with a rectangular cross section, and bone lines 12, 12... are provided at each ridgeline portion, and the bent portions of each row line 11 are bent. It is inserted like a stitch (Fig. 1,
Figure 2).

A curl 11a is formed at the end of each row line 11 on the end surface periphery of the body netting 10, and the curls 11a, 1
The outer frame lines 13, 13, . . . are inserted through the portions 1a. Each outer frame line 13 is independent on each of the four sides forming the periphery of the trunk net 10, and both ends of each frame line 13 are locked by being wrapped around the bone lines 12, 12.

Middle frame lines 14, 14, . . . parallel to the outer frame lines 13, 13, . However, the middle frame lines 14, 14, . . . may be provided as necessary depending on the length of the body net 10. Each middle frame line 14 is independent on each of the four sides of the trunk net 10, and is inserted by sewing through the bent portions of the row lines 11, 11, and then fixed by wrapping both ends around the bone lines 12, 12. There is.

The body net 10 and the lid net 20 are coils 31, 31.
It is fixed by connecting the outer frame lines 13, 13, . . . , which are opposed to each other, to each side of the peripheral frame 22 via . In addition, at this time, the tip of each bone line 12 is inserted into a turn 22a formed at a corner of the peripheral frame 22, and by providing a fold 12a,
The lid screen 20 can be fixed more completely (FIG. 2).

The body net 10 having such a configuration has outer frame lines 13, 13...
, and both ends of the middle frame lines 14, 14... are the bone lines 12, 1.
2, the dimensions of each surface are kept constant, and in particular, the dimensions of each side of the end surface are fixed to the outer frame line 1.
Since it is fixed by 3, 13, etc., there is no risk of the overall shape being deformed. However, trunk net 1
The angle formed by each surface forming 0 is that each surface has a bone line 12
Since it can rotate around the body, it is not possible to maintain a right angle unless at least one of the lid nets 20 is attached, but on the other hand, by utilizing this fact, the body net 10 can be folded flat, and it can be easily transported to the site. When transporting, the volume can be minimized. Moreover, if one of the lid nets 20 is attached to one end of the body net 10 at the site, the body net 10 can be
Lid net 20, bone lines 12, 12... and outer frame lines 13, 1
3... and the middle frame line 14, 1 inserted as necessary
Since the entire body is supported by 4..., the trunk net 10
The open state of the other end can maintain an almost perfect rectangular shape, and the stone filling operation can be carried out smoothly. Incidentally, once the stone filling is completed, the other lid net 20 may be attached to complete the entire structure.

Effects of the invention As explained above, according to this invention, the bone line is inserted into the ridgeline part of the body mesh, and the outer frame line is inserted through the curl provided at the end of the row line on the periphery of the end face of the body mesh. By wrapping and locking both ends of the outer frame line around the bone line, the dimensions of each side of the periphery of the end face of the body net can be kept together by the outer frame line, so that the cover line can be attached to one end face. By attaching this, the other end can be held in the predetermined open state even before attaching the lid net, and therefore the filling work can be carried out without having to create a special opening. It has the excellent effect of being able to be implemented smoothly.

In addition, the body net without a lid net can be folded flat, making it convenient for transportation. Since the wire is inserted through the bent part of the wire and fixed, the work on site is extremely simple, and the required man-hours are kept to a minimum, which is an excellent effect.
