Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fixing metal fitting for holding and fixing a joint portion such as a pipe material used for assembling a greenhouse.

[Conventional technology]

Conventionally, for fixing the pipe material in an orthogonal state,
There are structures described in JP-A-51-74158 and JP-B-41-7302.

The former is a band metal fitting that has a storage part that bends one elastic wire to store the intersecting part of the to-be-locked body, and is connected to the connection parts at both ends of this band metal fitting, and one end And a connecting member formed by bending to form a connecting portion. This fixing bracket lifts the connecting part toward the back of the pipe material,
The structure is such that the joint portion is rotated about the axis to push down the joint portion of the band metal fitting to tighten and fix the pipe of the accommodating portion.

The latter is formed by bending it into a U-shape that fits into a pipe to form an engagement surface with the pipe material, and further rotatably fitting a cam with an operating portion to the base end piece thereof.

[Disadvantages of conventional technology]

However, in the conventional fixing metal fittings described above, a relatively strong force is required to lift the connecting portion toward the back of the pipe material in the former case, and in the work, it is connected to the connecting portions at both ends of the band metal fitting. There was a drawback that it was easy to come off. Therefore, there is a problem in that it is inconvenient to use for assembling a frame of a greenhouse having many joints.

In addition, the structure is such that the connecting part is hooked on the back part of the pipe material and the connecting part is constantly pressed to fix the pipe. There is a drawback in that the force applied by the member to the band metal fitting is small, and as a result, not only the holding power of the pipe is weak, but also the risk of the pipe being disconnected is high.

Further, in the latter case, the base end piece has a structure in which a cam is used to fix it to the pipe material. However, if the action of the cam is increased in order to strengthen the degree of fixation, the portion holding the pipe material at the tip of the rod-shaped steel material It has a drawback that it easily bends or is deformed to reduce the holding power of the pipe material.

[Problems to be solved by the present invention]

The present invention has been made in view of the circumstances of the present invention, and it is an object of the present invention to provide a fixing metal fitting that can easily join orthogonally orthogonal pipe materials extremely firmly without requiring a strong force.

[Means for solving problems]

In order to achieve the above-mentioned object, this fixing member has the following structure. That is, a support member 1 that supports one pipe material A and another pipe material B in a crossed state, and a locking member 2 that pulls the support member 1 to tighten and fix the pipe materials A and B. The supporting member 1 is bent in a substantially semicircular shape at a portion close to both ends 4 and 6 of the wire 3 so as to be hooked on the outer peripheral side surfaces of one pipe material A and the other pipe material B in a crossed state. A portion 7 is provided, a curved portion 12 is formed in the center, and a penetrating portion 5 through which the engaging member 2 penetrates is provided at both ends 4 and 6 of the wire 3. On the other hand, the engaging member 2 is substantially a fishhook. The bent portion 8 has one end, and the other end serves as the bent portion 8, and the other end serves as the operation end portion 11. By rotating the operation end portion 11, the bent portion 8 is rotated on the side surface of the pipe material A,
When the maximum pressure contact point of the bent portion 8 with respect to the pipe material A is passed, the locking member 2 snaps to abut the side surface of the pipe material A and pulls the support member 1 at the penetrating portion 5 to cross it. The above one pipe material A and the other pipe material B are fastened and fixed.

[Action]

According to the above-mentioned fixing metal fitting, the bent portion 8 of the locking member 2 is provided on the penetrating portion 5 of the support member 1 hooked on each of the pipe material A and the pipe material B orthogonal to each other so as to follow the curve of the side surface of the pipe material. Insert and penetrate. When the operating end 9 is rotated, the locking member 2 rotates about the bent portion 8 as an axis. Therefore, the top 10 of the bent portion 8 presses against the side surface of the pipe, and the locking member 2 penetrates the through portion. 5, the end of the support member 1 where the penetrating portion 5 is provided is tightened, and at the same time, it acts so as to narrow the gap between them, and the crossed pipe materials A and B are extremely strongly joined and fixed.

〔Example〕

Next, an embodiment of the fixing fitting according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of a fixing fitting according to the present invention, and FIG. 3 is a perspective view showing a state in which orthogonal pipe materials A and B are joined and fixed by the fixing fitting. The fixing metal fitting of the present invention comprises a support member 1 for supporting the pipe materials A and B in a crossed state, and a locking member 2 for holding the fixed state. The support member 1 is a wire rod 3 made of steel.
Is bent so that substantially semicircular flexures 7, 7 are formed in the portions close to both ends 4, 6, and the bent portion is formed in the center.
12 is formed and hooked on the outer peripheral side surfaces of the pipe material A and the pipe material B in a crossed state, and the both ends 4 and 6 of the wire 3 are provided with penetrating portions 5 through which the locking member 2 penetrates. There is.

On the other hand, the locking member 2 is formed by bending the wire 9.
One end of the bent portion 8 is a substantially U-shaped bent portion 8. Further, the other end of the straight line becomes the operation end portion 9, and the bent portion 8 penetrates the penetrating portion 5 and is accompanied by the turning operation of the operation end portion 9,
It rotates on the side surface of the pipe material A as an axis.

According to this fixing metal fitting, the pipe materials are joined and fixed as follows.

As shown in FIG. 2, first, the pipe material B is placed on the flexible portion 7 of the support member 1. Still another pipe material A is inserted into the curved portion 12 formed by bending the support member 1 and penetrated between the curved portion 12 and both end portions 4 and 6 so as to be in a state orthogonal to the pipe material A. To do.

Next, as shown in the figure, the bent portion 8 of the locking member 2 is inserted into the engaging portion 5 along the curve of the side surface of the pipe material B. Further, the operation end 11 of the locking member 2 is connected to the bent portion 8
Rotate about 180 ° in the direction of arrow C about the axis. Then, the rotation causes the top portion 10 of the bent portion 8 to press against the side surface of the pipe material A to act as a lever, so that the locking member 2 strongly tightens the end portions 4 and 6 of the support member 1 at the penetrating portion 5. At the same time as raising, the interval between the end portions 4 and 6 is narrowed. Therefore, the pipe materials A and B are pressed by the support member 1,
It is firmly bonded and fixed. In this case, the locking member 2 rotates, and when the top portion 10 slightly exceeds the point where the top portion 10 is pressed against the side surface of the pipe material A most strongly, the operation end portion 11 moves to the third position.
As shown in the drawing, if the side end of the pipe material is stopped, the operating end 11 snaps to the side surface of the pipe material after passing the above-mentioned maximum pressure contact, and easily moves in the opposite direction. Since it does not rotate, the joined state of the pipe can be reliably maintained.

Further, as shown in FIG. 1, when the penetrating portion 5 is formed in an annular shape, the locking member 2 is removed even after the metal fitting is removed from the pipe material.
Since it is difficult to disengage from the support member 1 and both are integrated, one is convenient in handling without being lost.

[Function and effect of device]

As described above, according to the present invention, the supporting member is formed by bending the wire rod with a substantially semi-circular flexure, and forming the penetrating portions through which the locking member penetrates at both ends, while the bending portion is formed on the locking member. Is provided, and the bent portion is bent so as to form a substantially U-shaped bent portion, and when the locking member penetrates the through portion and rotates, the top portion of the bent portion is on the side surface of the pipe material. It is configured such that the pipe member is clamped and fixed by pressing and pulling the support member. In this case, the bending portion and the bending portion of the supporting member are hooked in mutually opposite directions along the outer peripheral surfaces of the pipe members that intersect at right angles.

Therefore, when the locking member pulls the support member very strongly, the tensile force acts in the direction in which the pipe members are pressed against each other. Therefore, due to the tightening force, the support member is not deformed so that the holding force of the pipe material is reduced, and the joining state of the pipe materials is less likely to be loosened. The stronger the pressing force of the support member to the side surface of the pipe material, the more firmly it can be fastened and fixed, and the wire material does not need to be particularly thick.

In addition, the substantially U-shaped bent portion acts so as to tighten up the support member when the pipe material is clamped and fixed in the penetrating portion of the support member.
There is no risk that the locking member will come off the support member, and the work is easy.

As described above, according to the present invention, the locking member that operates by lever application need not be operated with a strong force at all, and the work of tightening the joint portion of the pipe material or the like is easy. Therefore, there is an effect that labor for assembling a vinyl house or the like having many pipe material joining points can be reduced and the robustness thereof can be achieved.
