DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing and holding a pipe or the like to a fixing member such as a square bar.
The present invention relates to a fastener suitable for easily performing the fastening operation.

[0002]

2. Description of the Related Art Conventionally, in order to fix and hold a pipe disposed in a building such as a space above a ceiling, a fastening method as shown in FIGS. 5 and 6 is known. That is, in the case of FIG. 5, the pipe 1 forming the pipe system is connected to the locking portion 2b of the fastening fitting 2.
And a fixing member 4 such as a square bar fixed in the building is clamped by the clamping portion 2a of the fastening fitting 2, and the T-bar 5 standing in the building is locked by the fastening portion of the fastening fitting 2. 2
The hook 2c of FIG. 2b is hooked, and the screw 3 attached to the holding portion 2a of the fastening 2 is screwed together to tighten the square bar 4, thereby fixing and holding the tube 1.

In the case of FIG. 6, a square bar 4 is clamped by a locking portion 2b of a fastening fitting 2, and a C-shaped fitting (C-chan) 6 is hooked on a hook 2c of the locking portion 2b. This C-shaped bracket 6
, A tube 1 (not shown) is sandwiched between the
The screw body 3 attached to a is screwed together, and the square bar 4 is tightened to fix and hold the tube 1. In addition, fastening fittings as shown in FIG. 4 are also often used.

[0004]

However, when these conventional fasteners are used, since the fixing members 4 and the like are tightened by screwing the screw bodies 3, a large number of screw bodies 3 are fixed in a narrow space. It has to rotate each time, which requires a great deal of work for the tightening operation.

Further, it is difficult to confirm whether or not the tightening by the screw body 3 has been completed only by visual inspection of the screw body 3, and since there are many places requiring such work, the pipe body is required. It is desired to simplify the tightening work for fixing and holding 1.

The present invention has been made in view of such circumstances, and an object of the present invention is to fix and hold a pipe or the like to a fixing member such as a square bar. An object of the present invention is to provide a fastener suitable for easily performing a fastening operation.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a fastener for fixing a pipe or the like to a fixing member such as a square bar.
A holding portion having a U-shaped cross section for forming one side of the fastening metal body and inserting a tubular body or the like thereinto, and a pair of openings each being opened to the opposite holding portion and for inserting a fixing member or the like; An L-shaped locking portion that forms the other side of the bracket main body and is a remaining holding portion excluding the opening, and a protruding piece of the locking portion on at least one side of the L-shaped locking portion is rotatable. Attached, when rotated in the locking direction, the lock part is pressed and tightened so that it gradually rubs against a fixed member etc. inserted in the fastener body, and the fixed member and the tube are fixedly held And a swing / lock type / clamping means. Also, the swing-lock type clamping means is characterized in that the end side of the operating rod is formed as a bent part,
Further, on one surface of the bent portion at the end of the operating rod, a state display layer such as application or coloring of a fluorescent paint is formed.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an example of a fastener according to the present invention.

As shown in FIG. 1, the fastening fitting 10 is a tubular body 1.
4 and the like, a U-shaped holding portion 10a to be fitted, a locking portion 10b for hanging a fixing member 15 such as a building, and a U-shaped opening formed in the locking portion 10b and through which the fixing member 15 is inserted. It is constituted by a portion 10 c and a lock type clamp means 11 attached to the fastening fitting 10. Opening 1
0c is provided with a protruding piece 10d for preventing the fixing member 15 from hanging.
Is provided.

[0010] Swing-lock type clamping means 11 rotatably attached to the locking portion 10b of the fastening fitting 10
Is a lock portion 11a which presses and fixes the fixing member 15.
Is rotatably attached to the locking portion 10b via the pivot portion 13. A turning operation rod 11b extends from the base of the lock portion 11a, and the end of the operation rod 11b is twisted. To form a bent portion 11c.

Further, a hook portion 12 for preventing slip is formed at a tip portion of the lock portion 11a.
When a is rotated in the locking direction (see FIG. 2) with the pivot portion 13 as a fulcrum, the hook 12 is pressed so as to gradually rub against the fixing member 15, and the fixing member 15 is securely tightened.

In order for the lock portion 11a to satisfactorily press and fasten the fixing member 15, the shape of the lock portion 11a may be determined in relation to the shape and the distance of the fixing member 15, but the degree of rubbing is gradually increased. It is preferable to have a flat curve like an ellipse so as to apply an additional pressing force.

Although not shown, the lock portion 11a
Is an ellipse, the degree of rubbing against the fixing member 15 can be gradually increased by setting the pivotal portion 13 at a position that is more eccentric than the true center point.

The bent portion 11c on the end side of the operating rod 11b of the swing lock type clamp means 11 appears differently in the state of visual recognition when tightened or not tightened.
It facilitates visual discrimination. Therefore, the bent portion 11c
By forming a state display section 17 on one or both sides of which a fluorescent paint is applied or colored, visual confirmation can be made even more easily from a dark place or from a distance.

FIG. 3 shows a fixing member 15 such as a square bar fixed and bridged on the back side of the ceiling or the like. The other side shows a structure in which the T-bar 17 is fixedly held to the fixing member 15 via the fastening member 16 on the other side.

The basic structure of the fastening member 16 is the same as that of the fastening member 10. The holding portion 10a of the fastening member 10 serves as a holding portion 16a, the locking portion 10b serves as a locking portion 16b, and the opening 10c serves as an opening. As the portion 16c, the locking protrusion 10d corresponds to the locking protrusion 16d.

Thus, according to this embodiment, the pipe 1
4 and the like are assembled to the fixing member 15, and both members 14,
The operation of fixing and holding the fixing member 15 is performed only by rotating the operating rod 11b of the swing-lock type clamp means 11 so that the locking portion 11a is pressed so as to rub against the fixing member 15 and tightened. The tightening operation can be performed easily as compared with the case where the body is screwed together, and the workability can be reduced even when a large number of fasteners 10 (16) are used.

Further, since the end of the operating rod 11b of the swing-lock type clamp means 11 is a bent portion 11c, the position of the bent portion 11c changes due to the rotation.
Whether or not the fastening fitting 10 (16) is in the tightened state
It can be easily confirmed by visual inspection of the bent portion 11c. Further, since the state display section 17 is formed in the bent section 11c by applying or coloring a fluorescent paint, visual confirmation can be performed more easily.

[0019]

As described above, according to the first aspect of the present invention, the operation of tightening the pipe can be performed easily and in a short time as compared with the conventional case where the screw is screwed together. Can be. Further, the pipe and the fixing member are inserted and fitted in a single holding portion formed in a U-shape, and the fixing member is swung.
Since it is configured to press the pipe through the fixing member by pressing by the lock type / clamping means, the number of parts can be reduced and cost can be reduced, and the durability is simple structure. And simplicity of operation can be achieved.

According to the second or third aspect of the present invention, it is effective to press the lock portion so as to gradually rub against the fixing member.

According to the fourth or fifth aspect of the present invention, whether or not the fastener is in the tightened state can be easily visually confirmed.
