DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reticulated body connecting structure for connecting reticulated bodies, and more particularly, to a reticulated body connecting structure having a plurality of longitudinally extending vertical lines and a plurality of laterally extending horizontal lines each formed of a wire. The present invention relates to a reticulated body connection structure for connecting reticulated bodies.

[0002]

2. Description of the Related Art FIGS. 1 to 4 show a conventional net connection structure for connecting nets constituting a fence, a gate and the like. Each of the two nets 1a and 1b to be connected to each other has a grid-like shape composed of a plurality of vertically extending vertical wires 2 made of a steel wire or a stainless steel wire and a plurality of horizontal wires 3 also made of a steel wire or a stainless steel wire. Are formed by welding each other. Each of the connecting tools 4 and 5 includes a flat portion 6 and bent pieces 7 bent from right and left ends of the flat portion 6 at right angles. As shown in FIGS. 3 and 4, one connecting tool 4 is provided with a screw insertion hole 8 in the planar portion 6,
The other connecting tool 5 is provided with a screw hole 9 in the planar portion 6.

As shown in FIGS. 2 to 4, the two reticulated bodies 1a and 1b sandwich the vertical lines 2 at both ends thereof from the front side and the back side with the flat portions 6 of the connecting members 4 and 5, respectively.
The male screw 10 inserted into the screw insertion hole 8 was connected by screwing and screwing into the screw hole 9 (at this time, as shown in FIG. 4, the vertical lines at both ends of the two net-like bodies 1a, 1b). 2 is located between the bent pieces 7 provided on both side ends of the connecting tools 4 and 5).

In the case of this conventional connection structure, even when the male screw 10 is tightened, the bent piece 7 and the curved portions 11 having a circular arc cross section provided respectively at the upper and lower ends of the connecting tools 4 and 5 are provided. The inner surface was not pressed by the vertical line 2 and the horizontal line 3, respectively.

[0005]

The conventional mesh connection structure can connect the two meshes 1a and 1b using only one male screw 10 for a pair of connecting members 4 and 5. Therefore, there is an advantage that the manufacturing cost of the connecting tools 4 and 5 can be reduced, the working efficiency can be improved, and the working cost can be reduced. However, since the two nets 1a and 1b are connected by sandwiching the vertical line 2 between the two flat portions 6 of the connecting members 4 and 5, the net 1 is no matter how strongly the male screw 10 is tightened.
There has been a problem that it is impossible to prevent a and 1b from rotating in a plane parallel to the plane portion 6 (a plane parallel to FIG. 1) and from rotating about the vertical lines 2 at both ends as rotation axes.

The present invention has been made in view of such a conventional situation, and an object of the present invention is to use only one male screw for a pair of connecting members and not to rotate the mesh members with respect to each other. Is to provide a mesh connection structure that can be connected as described above.

Another object of the present invention is to provide a mesh connection structure in which the mesh is not shifted in the horizontal direction (or the vertical direction), and the mesh is not likely to fall out between the connectors.

Another object of the present invention is to provide a mesh connection structure which can connect the nets well even if the interval between the vertical lines or the horizontal lines of the two nets greatly varies. is there.

Another object of the present invention is to provide a mesh connection structure capable of inserting and tightening screws from both the front and back sides of the mesh.

[0010] Still other objects of the present invention will become apparent from the following description.

[0011]

A reticulated body connection structure according to the present invention includes a plurality of vertically extending vertical lines made of a wire and a horizontally extending horizontal line made of a wire.
In a net connection structure for connecting two nets, a first connection tool having a screw hole or a screw insertion hole, a linearly extending groove-like portion, a screw connection hole or a screw hole, and a second connection tool having a recess. And a second connector, wherein the groove-shaped portion of the first connector is fitted into the horizontal line (vertical line) of each mesh member, and is inserted into the concave portion of the second connector. The vertical line (horizontal line) of each net is penetrated, and a male screw inserted through the screw insertion hole is screwed into the screw hole or a separately prepared nut, and the first connector and the second The horizontal line (vertical line) in which the groove between the first connecting members is fitted into the groove, by tightening in a direction in which the distance between the connecting members is reduced.
A part of the second connector is pressed by the vertical line (horizontal line) that has penetrated into the concave portion, so that the first connector and the second connector are located between the first connector and the second connector. Each net is sandwiched between them.

In the coupling structure of the present invention, the groove of the first connector is fitted with the horizontal lines (vertical lines) of the two nets fitted in the linearly extending grooves of the first connector. Each of the mesh members is formed by the first connecting member and the second connecting member such that the portion is pressed against the horizontal line (vertical line) and a part of the second connecting member is pressed against the vertical line (horizontal line). By being sandwiched between the mesh members, the rotation of the mesh member is strongly restrained by the groove portion, so that it is difficult for the two mesh members to rotate relative to each other in any direction.

In addition, since the vertical line (horizontal line) has penetrated into the concave portion of the second connector and cannot go out of the concave portion,
There is no risk that the net-like body shifts in the horizontal direction (or the vertical direction) and comes off from between the connecting tools.

Further, as long as the vertical line (horizontal line) penetrates into the recess of the second connector, even if the variation between the vertical lines (horizontal line) of the two nets becomes large, the connection of the nets is not hindered. Does not occur.

Further, since the two nets can be connected to each other by using only one male screw for a pair of connectors, the manufacturing cost of the connectors is reduced, the working efficiency is improved, and the working cost is improved. Can also be reduced.

Further, if the first connector can be used only as the first connector and the second connector can be used only as the second connector, the vertical lines and the horizontal lines are formed in a grid. Strictly speaking, as in the case of meshes or the like welded to each other, when connecting a mesh having a structure in which the vertical line and the horizontal line are not in the same plane, for example, the first connector is a mesh of the mesh. There is a restriction that only the front side can be arranged, and the second connecting device can be arranged only on the back side of the mesh body. There is a restriction that the male screw can be inserted and tightened only from one of the front side and the back side.

However, if each connecting device has both a groove portion and a concave portion, and any connecting device can be used as both the first connecting device and the second connecting device, either of the connecting devices can be used. Connections can also be placed on either the front or back side of the mesh, so if either connection has a threaded hole, the insertion and tightening of external threads can be done from either the front or back side of the mesh. Will be able to do it.

Is also good. That is, the groove 13 of the first connector 12 (or the second connector 17) is fitted into the vertical line 2, and the concave portion 16 of the second connector 17 (or the first connector 12). The horizontal line 3 may enter the inside.

In the above embodiment, the screw hole 15 is provided in the first connector 12 and the screw hole 18 is provided in the second connector 17. A screw hole may be provided in one connector and a screw insertion hole may be provided in the second connector. Alternatively, both may be screw insertion holes, and the male screw may be tightened using a separately prepared nut.
