Description

[Detailed Description of the Invention] The invention relates to a metal fitting used when attaching, for example, an antenna, a speaker, or an advertisement to a columnar structure such as a utility pole or a ship's mast.

When attaching antennas to columnar structures of various diameters such as telephone poles and masts of ships, metal fittings such as those shown in Fig. 1 have conventionally been used.

In Figs. 1 a to d, 1 is a columnar structure, 10 is a mounting bracket, 20 is a body to which the mounting bracket 10 is attached, and a and b are columnar structures with relatively large diameters. When attached to an object, Ct d in the same figure shows the case where it is attached to a columnar structure with a relatively small diameter.

For the above-mentioned mounting, the metal fitting 10 is composed of a main metal fitting 11 and first and second auxiliary metal fittings 121 and 122 that are selectively used.

The above-mentioned main metal fitting 11 is bent into a V-shape and the support is attached to the part 13.
, the handle portion 14 and the attached body have a body support portion 15.

Further, the first auxiliary metal fitting 121 has the same ■-shape as the pillar mounting portion 13 of the main metal fitting 11, and the second auxiliary metal fitting 122 is a flat plate metal fitting.

These first and second auxiliary fittings 12. ．． 12□ is a bolt 16 with either one selected for the main metal fitting 11.
1, 16□ and Natsu 17. ．． It is fixed at 17□.

In such a structure, when used for a columnar structure with a relatively large diameter, the first auxiliary fitting 121 is used to
It is fixed to the columnar structure 1 as shown in Figures a and b.

In other words, with the ■-shaped parts facing each other, bolt 16□
, 162 and Natsu 17□.

The tightening is fixed at 172.

In this case, the tightening of bolts 16□ and 16□ can be varied within the range of length 1, which is slightly shorter than the length of the possible part.
It is possible to attach it to a columnar structure with a minimum diameter shown by the solid line in the figure and a maximum diameter shown by the broken line in the figure.

In addition, when used for columnar structures with relatively small diameters,
It is fixed to the columnar structure 1 using the second auxiliary metal fitting 12□ as shown in FIG. 1c and d.

In this case, since the auxiliary fitting 12□ is a flat plate, it can be attached to a columnar structure having a minimum diameter as shown by the solid line in the figure and a maximum diameter as shown by the broken line in the figure.

With the above structure, it is certainly possible to install the columnar structure regardless of its diameter within a certain range, but in order to widen the variable range to some extent, the first step is to
, a second auxiliary metal fitting and another auxiliary metal fitting not mentioned here are required, and multiple types of auxiliary metal fittings are prepared.
I had to choose and use them.

Therefore, it is necessary to be careful not to lose these auxiliary fittings, and in addition, during actual work, it is a hassle to select one of them, which is not desirable in terms of workability. .

This invention was made in view of the above points, and the purpose is to provide a fitting that can be used for a wide range of columnar structures from small diameters to large diameters with one auxiliary fitting for the main fitting.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 2 shows an embodiment of this invention, and the same parts as in FIG. 1 are given the same reference numerals.

This idea differs from conventional ones in the shape of the auxiliary metal fittings.

That is, the auxiliary fitting 30 of the mounting fitting 1 according to this embodiment
has a trapezoidal shape as shown in FIG.

The inclined part 31a of the auxiliary metal fitting 30 which has a trapezoidal shape in this way
v31b has a bending angle α equal to the bending angle α of the main metal fitting 11.

In addition, the protruding piece 33 of this auxiliary metal fitting 30 and the inclined part 31
Ribs 32 are formed for reinforcement at the corners a and 31b.

The rib 32 is formed by forming a recess by pressing or the like, and various methods are conceivable.

Next, how to use this configuration will be explained.

First, when the diameter of the columnar structure 1 is relatively large, the second
As shown in the figure, the auxiliary metal fitting 30 is fixed to the main metal fitting 11 so that the projecting piece 33 projects outward.

This fixing means is the same as the conventional one shown in FIG. ．． This is done with nuts 16□ and 17□, 17°.

In this case as well, the tightening of bolts 16t and 16□ can be varied within the range of length 1, which is slightly shorter than the possible length range, and can be installed on a columnar structure with a minimum diameter shown by the solid line in the figure and a maximum diameter shown by the broken line in the figure. becomes possible.

Further, when the diameter of the columnar structure 1 is relatively small, the third
As shown in the figure, the auxiliary metal fitting 30 is used with the auxiliary metal fitting 30 turned over so that the protruding piece 33 protrudes inward, contrary to the case shown in Fig. 2, and is fixed to the main metal fitting 11 in this state. .

In this case as well, the tightening of the bolt 161.16□ can be varied within the range of length 1, which is slightly shorter than the possible length range, and the minimum diameter is shown by the solid line in the figure, and the maximum is the diameter shown by the broken line in the figure. Installation is possible.

If the above structure is to be mounted using a metal fitting, it is possible to use a single auxiliary metal fitting to cover everything from small-diameter columnar structures to large-diameter columnar structures, which is extremely efficient and economical. Become.

Note that this invention is not limited to the above-mentioned embodiments.

For example, the protruding piece 33 of the auxiliary metal fitting 30 may be formed with a fine waveform 34 as shown in FIG. 4 to provide an anti-slip effect.

Furthermore, the same effect as that of the above embodiment can be obtained by mounting the entire metal fitting in a shape as shown in FIG.

In this case, the main metal fitting 11 is composed of a first main metal fitting 111 and a second main metal fitting 11□, and these first and second main metal fittings 11
．． ．． I try to make a ■ shape at 11 degrees.

Furthermore, the mounting according to this invention can be used even if the columnar structure is not cylindrical as in the above embodiment; for example, it can also be used for a columnar structure or a columnar structure having a rectangular cross section.

As explained above, according to this invention, there is a main metal fitting whose part that contacts the columnar structure has a ■ shape, and an auxiliary metal fitting that is fixed to the main metal fitting with bolts and nuts so as to sandwich the columnar structure. For installation, the above-mentioned auxiliary metal fitting is bent into a trapezoidal shape in the metal fitting, and the protruding piece of the trapezoidal auxiliary metal fitting is bent inward or outward from the opening of the ■-shaped part of the main metal fitting. The structure is such that you can select which side to protrude from and fix it with bolts and nuts.
With one auxiliary metal fitting, it can be used for a variety of columnar structures, from small diameter ones to large diameter ones.Furthermore, since only one auxiliary metal fitting is needed, it is highly workable and economical. We can provide mounting hardware that is extremely useful when attaching antennas, microphones, speakers, advertising materials, etc. to the masts of ships and ships.
