Abstract

PURPOSE:To enable rapid and secure fixation by inserting one end of a band of reverse U-shape into the through hole of a fixing surface and locking it when putting the band on the upper surface of a fixed object such as a piping and fixing vises and the like so as to fix the fixed object on the fixing surface. CONSTITUTION:While a through hole 21 and a vis hole 22 for a machine screw are formed on a metallic plate-form fixing surface 20, a metallic band 40 is formed by providing a locking member 44 extending upward obliquely from a bending part 43 bent outward is provided at one end of a semicircular arc 41 whose outer form is almost coincident to a cylindrical fixed object 1 such as a piping at the upper side, and providing a fixing seat 46 extending outward on the fixing surface 20, and a vis hole 45 is opened on the surface. And when the fixed object 1 is fixed, the band 40 is put on the fixed object 1, the locking member 44 is inserted in the through hole 2 on the fixing surface 20 and in conditions where the tip is locked to the reverse side 23 of the fixed object 1, a vis 12 is inserted into the vis hole 45 of the fixing seat 46, and the vis 12 is screwed up to the vis hole 22 of the fixing surface 20 so as to fix the fixed object 1 elastically.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for fixing pipes such as joints and other articles having a round or square outer diameter.

[0002]

2. Description of the Related Art FIG. 4 shows a general fixing metal fitting used conventionally. This is an inverted U-shaped band metal fitting 10
Cover the fixed object 1 and attach the fixed seats 11 that project to both sides.
It is fixed to the fixed surface 2 with a set of bolts and nuts or screws 12.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the case of 0, there is no problem when the size of the fixed object 1 is always constant, but for example, when the fixed object is a burr such as a casting and the size is different, the fixing seat 11 of the band is fitted to the fixing surface 2. There is a case where it cannot be fixed or the fixed object 1 is loosened and cannot be fixed because the band 10 sags. Further, it is necessary to provide two fixing screw holes 3 on the fixing surface 2 and fix them at two positions, which is troublesome for the work. The present invention provides a fixing metal fitting that can be securely fixed even if the fixed material has some size, and can be fixed at one place of a U-shaped band metal fitting.

[0004]

SUMMARY OF THE INVENTION The gist of the present invention is a metal fixture which covers an upper surface of a fixed object with an inverted U-shaped band and fastens the fixed object to a predetermined fixing surface by a screw or the like. There is a fixing surface having a through hole at a fixing position, and one end side of the band lower portion is inserted through the through hole opened in the fixing surface, and extends obliquely upward from a bent portion bent to the outside of the fixing surface. The other end side of the lower part of the band has a locking part that locks on the back side, and is composed of a metal band having a fixing seat protruding outward on the fixing surface, and The fixing fitting is characterized in that one end side is inserted into a through hole of the fixing surface and locked at the back surface of the fixing surface, and the fixing seat at the other end is tightened to the fixing surface to fix the fixed object.

[0005]

Since the present invention has the above-mentioned structure, when one end side of the band is inserted into the through hole of the fixing surface and the locking portion is locked on the back surface of the fixing surface, the locking portion is diagonally upward from the bent portion. Since it extends upwardly, there is a margin between the upper surface and the back surface, and this amount becomes a margin amount of the length that covers the fixed object on the upper part by the elasticity of the metal band itself. Therefore, when the other end of the band is screwed to the fixing surface, the spring action works in the part that extends obliquely upward from the bent part, absorbing the band length depending on the size of the fixed object and securely fixing it. Objects can be fixed to the fixed surface. Further, since there is only one screw fixing point with screws or the like, the work can be easily performed.

[0006]

FIG. 1 shows a first embodiment of the present invention. In FIG. 1, a metal plate-shaped fixing surface 20 is provided with a through hole 21 and a screw hole 22 for screws. Reference numeral 40 denotes an inverted U-shaped metal band, and an upper portion thereof has a semi-circular arc portion 41 which is substantially in conformity with the cylindrical fixed object 1 such as a pipe. One extending downward from this semi-circular arc portion 41 is inserted into the through hole 21 of the fixed surface 201, extends obliquely upward from the bent portion 43 that bends outward, and is locked to the back surface 23 of the fixed surface 20. Have. The other extending from the semi-circular arc portion 415 to the lower side has a fixing seat 46 which projects outward on the fixing surface 20 and has a screw hole 45 for locking with the screw 12.

The metal band 40 is a thin plate having both elasticity and rigidity and a thickness of about 0.5 to 3 mm. When the screw 12 is tightened, the fixed seat 46 of the band 40 comes close to the fixed surface 20, and the gap between the fixed rear surface 23 of the bent portion 43 extending obliquely upward of the locking portion 44 acts as a spring action, and the length of the band is reduced. Absorb the shortfall. Therefore, the fixed object 1 is closely attached and securely fixed.

A second embodiment is shown in FIG. The band 50 of this embodiment has an inverted U-shape with a substantially square shape, and a recess 52 for contacting and locking the upper surface of the fixed object 5 is provided at the center of the upper surface. In this case, since the upper portion of the band corner portion 51 has an inverted U shape, any of the cylindrical fixed object 1 of the above-mentioned embodiment and the angular fixed object 5 as shown in the figure can be used as long as it can enter the inside. good. Further, the concave portion 52 is locked to the upper surface of the fixed object 5, and the spring action also works between the upper surface of the fixed object 5 and the band 51.
Absorbs variations in the height of the fixed object 5.

Next, a third embodiment is shown in FIG. The band 60 of this embodiment is U-shaped from the bent portion 63 to the locking portion 64 as shown in the figure, and a larger gap is formed between the band 60 and the fixed back surface 23 in the vertical direction than in the above embodiment. Further, the locking portion 64 for locking the back surface 23 of the fixed surface 20 is a substantially horizontal surface so that the fixed back surface 23 is not scratched. In this case as well, by tightening the screw 12, the fixed back surface 2 of the bent portion 63
The gap with 3 absorbs the variation in the height direction of the fixed object 5 and acts as a spring action, so that the fixed object can be fixed securely.

[0010]

As described above, the fixing metal fitting of the present invention,
By absorbing the band length depending on the size of the fixed object, the spring action works and the fixed object can be fixed securely. Also, since there is only one fixing point with screws or the like, the fixing work can be performed easily.
