The present invention relates to an armrest mounting apparatus used for mounting a device such as a signal lamp.
[0002]
[Prior art]
A pole base frame is composed of a central piece and upper and lower pieces provided on both upper and lower sides of the central piece, the pole base frame is fastened to a power pole by a band body, and the power pole side is attached to the central piece of the pole base frame. There is a structure in which the end of the tightening bolt that is protruded through is passed through the arm metal engaged between the upper and lower pieces of the device base frame and screwed into the tightening nut (for example, Patent Documents) 1).

[Problems to be solved by the invention]
Since the conventional example adopts a configuration in which the mounting base frame having a U-shaped cross section is attached to the electric pole by the band body on the outer surface side of the central piece, the configuration of the mounting base frame becomes complicated in relation to the band body. Therefore, the weight increases.
[0005]
The present invention has been devised to provide a device that is lighter as a whole and can improve the workability of the armrest column as compared with such a conventional example.
[0006]
[Means for Solving the Problems]
A central piece comprising a superposed piece and upper and lower inclined piece pieces gradually approaching each other in the direction of the superposed piece piece, and an upper piece and a lower piece that are connected to the inclined piece piece of the central piece so as to face each other. A base frame is configured, and the device base frame is fastened to the power pole by a band body by engaging a curved edge provided at a free end edge of the upper and lower pieces with a band body, and a central piece of the device base frame is superposed The tip of the tightening bolt that penetrates and protrudes from the utility pole side to the part piece is passed through the armature overlapped with the overlapping part piece, and the tightening nut is screwed together. Are configured to match each other.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of a brace armor column apparatus according to the present invention. FIG. 1 is a partially cutaway plan view, and FIG. 2 is a partially cutaway side view.
[0008]
In the figure, reference numeral 1 denotes an apparatus base frame. The apparatus base frame 1 includes a central piece 2 composed of a superposed piece 2a and upper and lower inclined pieces 2b, 2b that gradually approach each other in the direction of the superposed piece 2a. 2 is composed of an upper piece 3 and a lower piece 4 which are connected to the inclined portion piece 2b. The device base frame 1 has an annular shape formed by engaging curved edges 3a, 4a provided on the free end sides of the upper piece 3 and the lower piece 4 on the periphery of the utility pole D and interposed between the upper and lower pieces 3, 4. In the connecting piece 5a, the band bodies 5, 5 pivotally connected (connected) by the vertical axis 6 laid between the upper and lower pieces 3, 4 are wound around the utility pole D, and the tightening receiving piece 5b of the opposing band bodies 5, 5 is wound. , 5b, and a tightening bolt 7 and a tightening nut 8 at the tip thereof are screwed and tightened to the utility pole D.
[0009]
A pair of tightening bolts 9 and 9 are passed through the overlapping part 2a of the central piece 2 of the apparatus base frame 1 from the electric pole D side, and the head part 9a is locked to the overlapping part 2a. The bolt end 9b protruding from 2a is passed through the arm metal 10 superposed on the overlapping part 2a, and a tightening nut 11 is screwed and tightened to the end 9b to tighten the arm metal 10 to the device base frame 1, It is a thing.
[0010]
The tightening bolt 9 is a so-called square root bolt, and the square root is provided in the overlapped piece 2a and the brace 10 overlaid on the overlapped piece 2a (the through hole 13 on the brace 10 side). And the tightening bolt 9 is prevented from co-rotating when the tightening nut 11 is screwed and tightened to the tip 9b portion, so that the operation can be performed reliably.
[0011]
The arm bracket 10 is made of a square steel pipe, and has a pair of opposed pieces 10a, 10a whose outer width (vertical width) is substantially the same width as the overlapping piece 2a of the central piece 2 of the device base frame 1. It is.
[0012]
Incidentally, FIG. 12 shows a reinforcing piece interposed between the upper and lower pieces 3 and 4 of the apparatus base frame 1.
[0013]
In order to mount the brace 10, the device base frame 1 and the band bodies 5, 5 are formed into the vertical axis 6 (in the embodiment, it is constituted by a bolt rod 6 a and a nut 6 b screwed to the bolt rod 6 a). First, by assembling together using the annular connecting piece 5a, passing the fastening bolt 7 through the fastening receiving piece 5b, 5b of the band body 5, 5, and screwing the fastening nut 8 to the tip of the bolt. The device base frame 1 is fastened to the utility pole D.
[0014]
Then, the tip 9b of the fastening bolt 9 assembled in advance on the device base frame 1 is protruded from the arm metal 10 so as to penetrate the through hole 13 provided in the arm metal 10, and the nut 11 is screwed to the tip. It can be mounted by tightening.
[0015]
【The invention's effect】
The present invention provides the above-mentioned polymerization by superposing an armature having the same width diameter as the overlapping portion on the overlapping portion of the central piece composed of the overlapping portion and the upper and lower inclined portion pieces close to each other in the overlapping portion direction. Since the device base frame provided with the piece is tightened by the tightening bolt and the tightening nut screwed to the device base frame, the arm metal can be firmly tightened to the device base frame. In other words, since the width of the device base frame and the arm metal are the same, the tightening load by the tightening nut is received by the entire overlapped part on the device base frame side, and is distributed by the inclined part connected to the overlapped part. Therefore, the brace can be firmly mounted.
