DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting required for assembling a greenhouse or assembling a seaweed aquaculture frame rope.
The present invention relates to a connecting fixture such as a rope and a wooden bamboo material.

[0002]

2. Description of the Related Art FIGS. 9 and 10 show a conventional fixing fixture used for this kind of application . Connection fixing bracket A in FIG.
Is bent inward at the lower end of the horseshoe-shaped U-shaped plate
Tightening parts 2 and 3
A tool is inserted to connect the two pipes. FIG.
Is connected to the pipe with bolt D and nut F inserted into the pipe.
Tied. Furthermore, conventionally, it is bonded and joined by welding or the like.
Sometimes fixed.

[0003]

THE INVENTION Problems to be Solved] binding fixed metal shown in FIG. 9
Koo, now, that has been widely used in the assembly of greenhouses.
This connection fixing bracket A is inconvenient because its use is limited only to the connection and fixing of an iron tube or a vinyl tube having a predetermined diameter. Also , the strength of the connection and fixation is weak, and in the case of an emergency such as a typhoon , the strength of the connecting portion is often insufficient, which has been one of the causes of a major disaster. In addition, there is a problem that the work is troublesome when removing.
Furthermore, since the coupling fixture A of FIG. 9 is manufactured by forming and processing a thin iron plate, there is also an economic problem that the unit price is high.

Further, as shown in FIG.
The structure to tie is to make a hole in the pipe and
This requires a tightening operation, and has a problem in that assembly and removal are troublesome and inconvenient.

[0005] In the case of welding, there is a problem that a special technique called welding is required, which is troublesome and inconvenient.

[0006] Further, the coupling fixture shown in FIGS. 9 and 10
Is used to assemble ropes , natural materials such as wood and bamboo into a framework, and these can be strongly connected.
There was a problem that could not be done.

By the way, it is easy to connect agricultural columns and the like.
The structure shown in Fig. 12 has been developed
(Japanese Unexamined Utility Model Publication No. 56-18052). This figure
The connection fixing bracket A is formed by bending the wire at the center in a U-shape and
Then, bend the both ends of the fitting portion 1 in a direction approaching each other.
I have. As shown in FIG.
The two columns 4 to be inserted are inserted into the fitting portions 1 and the elasticity of the wire is adjusted.
The struts 4 are pinched and connected. Combination fixture of this structure
A has a feature that the column 4 can be easily connected. But
However, the coupling fixture A of this structure has two wires due to the elasticity of the wire.
Can not be firmly connected because the support 4 is sandwiched and connected.
There are drawbacks. Also, in order to firmly connect the column 4 ,
Use hard and hard wire, easily elastically deform and fit
It becomes impossible to put two columns 4 in one. Fitting part
This is because there is a very strong force to open both ends of 1.

[0008] The present invention relates to the conventional connecting and fixing metal fitting.
Developed to eliminate the disadvantages of
Therefore, an important object of the present invention is to
To provide a coupling fixture capable of firmly coupling a material to be coupled.
It is in.

[0009]

A is to wind the wire three times in a circular loop and tighten
I have.

[0011]

FIG. 5 to FIG. 8 show the connecting fixture A of the present invention .
As shown, the wire is formed into a horseshoe shape and
The fastening portions 2 and 3 are provided at both ends of the fitting portion 1.
You. The horseshoe-shaped insertion part 1 is going to be joined from the opening
The iron tubes B and C as the materials to be joined are put.

As shown in FIG. 5 , the annular portions of the fastening portions 2 and 3 at both ends of the fitting portion 1 are drawn together and overlapped.
At the same time, the driver E
Insert the screw and rotate this driver E to tighten
The wires of the fitting part 1 near the parts 2 and 3
To connect. The annular fastening parts 2, 3 are shown in FIG.
As described above, when twisting the wire, there is sufficient support
3 times so that the wire wrapped around does not stretch linearly
Rolled up and strengthened.

[0013] The tightening of the ring-shaped part 2, 3, shown in Figure 4
Sea urchin, since both are wound in the same direction, attracted
When they are placed on top of each other ,
Makes it easy to insert a straight rod with the loop straight
It has become.

[0014] As shown in FIG .
Iron pipes B and C, and tighten both fastening parts 2 and 3
, The fitting portions 1 intersect in an X-shape. Fitting
The intersection of the inlet 1 is straightened to both fastening parts 2,3.
When inserting and rotating, the wire of the fitting part 1
It is a part to be done. In other words, the two who approached each other
The straight rod of the driver E is attached to the ring of the tightening parts 2 and 3.
When inserting and rotating, the part of the wire that intersects in an X-shape
The opening of the fitting part 1 is deformed
The department is tightened.

As described above, according to the present invention, it is possible to use
Features that can easily, easily, and firmly connect composite materials
There is. That is, the connecting fixture of the present invention
As a mold, it is a fitting part, and it is fastened to both ends of this horseshoe-shaped fitting part.
The tightening part is provided with a wire several times.
While winding into a ring, the direction of winding of the ring is
With the material to be joined and both close to each other,
The direction should be such that a straight rod can be inserted into the tightening part.
Because it is. The coupling fixture with this structure
After putting the material to be joined into the
And insert a linear rod, such as a screwdriver, into the
By rotating the workpiece, the material to be bonded can be firmly tightened.
Wear. In particular, the connecting and fixing bracket of the present invention uses a wire a plurality of times.
Since it is wound in a ring shape and used as a tightening part,
If you insert a straight rod and rotate it many times and tighten tightly
The wire of the tightening part may return to a straight line
No. For this reason, the linear lock passing through both
The more you rotate the arm, the stronger the wire
Realizes the feature of being firmly tightened by being pulled.

The material to be tightened in this state is slightly thicker.
Even if it is different, surely by the number of rotations of the linear rod
I can tighten. For example, when connecting thin bonded materials
Rotate the linear rod that has passed through both
The wire by loosening the wire.
Has the advantage that it can be tightly bound to connect the materials to be joined.
is there.

Further, the connecting and fixing metal fitting of the present invention uses a wire.
Formed into a horseshoe shape and wrapped its tip several times in a loop
It can be manufactured in different shapes, so it can be mass-produced at extremely low cost.
There are also features that can be used.

Further , the connecting and fixing metal fitting of the present invention has a
With the binder fastened, the loops of both fastening parts are
Insert a straight rod into this tightening part
Then, rotate the linear rod in the opposite direction to binding,
You can break unity. For this reason, the fixing of the present invention
The bracket can be assembled by simply connecting the materials to be joined.
Also, features that can be easily dismantled can be realized.

Still further, the connecting and fixing metal fitting of the present invention is
The number of rotations of the straight rod passed through the mounting
The degree to which the binder is tightened can be adjusted to an ideal state. This
Therefore, a member that can be spun extremely strongly, such as an iron tube, is connected
To do this, turn the straight rod passed through the tightening part many times.
Roll it up and unite it strongly, like wood, bamboo, rope,
Materials to be joined that cannot be tightened more than necessary
Reduce the number of rotations of the wire rod inserted through the mounting
The feature that can be connected to each member with ideal strength
is there.

That is, the coupling fixture according to the present invention is extremely
Simple and inexpensive even written to be produced Warazu, various of the binding Te
It is possible to connect the mixture in an ideal condition and very easily.
Realize outstanding features.
