Description

[0001]
[Industrial application fields]
The present invention relates to an armrest mounting device for a utility pole.
[0002]
[Prior art]
A band tie tightening piece in which a through hole is arranged in a band central piece, a bolt is passed through an appropriate through hole and a tightening piece is assembled to both ends of the band central piece, and a pair of T-shaped parallel pieces. A pair of anti-gradient members having a V-shaped cross section on one side of a horizontal rail is attached to the electric pole surface by bolting together the anti-gradient members of the arm metal support metal member welded to each other at right angles. There is a structure in which a brace is sandwiched between other pieces of a horizontal arm and fastened to the anti-tilt material by a bolt and a nut (for example, Patent Document 1)

[Problems to be solved by the invention]
The above-mentioned conventional example is a brace by combining a bracelet support metal constructed by welding a pair of horizontal rods and a pair of anti-tilt members together with a band body in which a band center piece and a fastening piece are assembled to each other with bolts. Therefore, the structure is complicated, and the handling of the constituent members is complicated.
[0004]
Also, the arm metal support hardware supports the arm metal by a bolt penetrated through the arm metal and a nut screwed to the bolt, and a U-shaped bolt arm metal is held and the nut is screwed into the metal arm. Although the above-mentioned document discloses a structure in which the arm support metal fittings are supported together, the former may cause the bolts to rotate together with the tightening of the nut, and the latter is the U Since the shift of the bracelet is prevented by the contact resistance between the character bolt and the bracelet, it is not necessarily perfect for preventing the shift of the bracelet.
[0005]
The present invention has been devised to provide a device that can obtain a stable attachment state of a brace to a utility pole.
[0006]
[Means for Solving the Problems]
Inner and outer frames in which upper and lower pieces are connected to a vertical piece relative to each other, and each of the upper and lower pieces, and an annular base portion of each band piece interposed between the upper piece and the lower piece, Are attached to each other by a nut bolted to the shaft bolt and a nut bolted to the shaft bolt, and the fastening receiving piece on the tip end side of each band piece wound with the power pole is mutually attached by a nut screwed to the bolt and the bolt. The inner and outer frames of the support bolts that are tightened to fasten the upper and lower frames to the power pole surface and sandwich a head having a diameter wider than the separation width between the upper and lower part pieces between the upper and lower part pieces of the inner frame. The tip through the vertical piece is inserted into a brace that is superimposed on the front surface of the vertical piece of the outer frame, and the nut is screwed together.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The drawings show one embodiment of a power pole arm attachment device according to the present invention, FIG. 1 is a partially cutaway plan view, and FIG. 2 is a longitudinal sectional view.
[0008]
In the figure, 1 is an inner frame, 2 is an outer frame, and inner and outer frames 1 and 2 are constructed by vertically connecting upper and lower pieces 1b, 2b, 1c and 2c to vertical pieces 1a and 2a. 2, the inner frame 1 is arranged on the inner side, while the arcuate edges 1b ′, 2b ′, 1c ′, 2c ′ of the upper and lower part pieces 1b, 2b, 1c, 2c are brought into contact with the arcuate circumferential surface of the utility pole. The upper and lower pairs of band pieces 5 and 5 are fastened to the electric pole (post) D surface so as to be in contact with each other.
[0009]
The band piece 5 is an annular base formed between the upper pieces 1b and 2b and between the lower pieces 1c and 2c of the inner and outer frames 1 and 2 formed by arranging the inner frame 1 inside the outer frame 2. 5b is interposed, and the nuts 7 are screwed into the ends of the shaft bolts 6 penetrating the base portion 5b and the upper pieces 1b and 2b, and the base portion 5b and the lower pieces 1c and 2c, respectively. In addition, the electric pole surface is wound and the tightening bolts 8 are passed through the tightening receiving piece 5a, 5a at the free end facing each other, and the tightening nut 9 is screwed to the bolt end protruding from the one receiving piece 5a. In addition, as described above, the inner and outer frames 1 and 2 are fastened to the electric pole D surface.
[0010]
It should be noted that a pair of through holes 10, 10 provided in the vertical piece 1 a of the inner frame 1 is engaged with a protrusion 11 provided corresponding to the vertical hole 2 a of the outer frame 2 so as to correspond to the through hole 10. A stable assembled state of 1, 1 is obtained.
[0011]
In the figure, 12 and 12 are outer frames in which the head 12a is engaged between the upper and lower pieces 2b and 2c of the inner frame 1, and the vertical piece 1a of the inner frame 1 and the vertical piece 1a are overlapped. The support bolts 12 are a pair of support bolts in which the tip 12b protrudes from the outside of the inner and outer frames 1 and 2, that is, from the electric pole D surface, through the through holes 13 and 13 provided so as to coincide with each of the two vertical pieces 2a. Is a hexagonal (or non-circular) head 12a having a wider portion than the separation width between the upper and lower pieces 1b and 1c of the inner frame 1 and interposing engagement with the upper and lower pieces 1b and 1c of the inner frame 1 The outer edge of the head 12a is pressed against one or both of the upper and lower parts 1b and 1c when an external force is applied in the rotational direction due to the relationship between the separation width between the upper and lower parts 1b and 1c and the outer diameter of the head 12a. Thus, its rotation is restricted.
[0012]
In the embodiment, the pair of support bolts 12 which are assembled to the inner and outer frames 1 and 2 fastened to the electric pole D surface using the band piece 5 and project from the electric pole D surface are connected to the upper and lower material ends of the vertical piece 14a. Between the upper and lower pieces 14b and 14c of the seat frame 14 and the through hole 15 provided in the vertical piece 14a of the seat frame 14 having a groove-shaped cross section formed by connecting the upper and lower pieces 14b and 14c to each other. A structure in which the through-hole 17 provided in the joined arm metal 16 is penetrated (relatively), and a support nut 18 is screwed onto the bolt tip 12b protruding from the arm metal 16 to attach the arm metal 16 to the utility pole D. It is.
[0013]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a device capable of freely attaching a brace according to the diameter of a utility pole, and the upper and lower frames that serve as a support base frame for the brace are a pair of two bands. Since it is configured to be fastened to the power pole surface with one piece, it is firmly attached to the power pole surface, and since the support bolt penetrates the arm metal, a stable mounting state can be obtained without any deviation of the arm metal. Even when the arm metal is fastened to the frame, it is possible to provide a device that can firmly and firmly perform the tightening operation by preventing the head from coming into contact with the inner frame and preventing the nut from rotating together.
