Description

[Detailed description of the invention] In a conventional arm-mounted pole, that is, a utility pole with a pair of arms attached, the number of rotations of the nut is required to move the nut to a predetermined position in order to attach the pair of arms to the pole. This requires a lot of labor and time, and since the cross arm holder touches the tightening band, it tends to create a gap between it and the side of the utility pole, resulting in a lack of safety.

This proposal aims to provide a support fitting that can be installed quickly and is highly safe.
a pair of substantially semicircular tightening bands 2,2 having
It has a connecting rod 4 for connecting arms which is inserted into the through holes 3, 3 drilled in the connecting pieces 1, 1, and a band tightening spiral 5, 5 is formed on the connecting rod 4, and arms at both ends. Metal fastening spirals 6, 6 are formed, and the outer diameter of these spirals 5, 6 is smaller than the inner diameter of the through holes 3, 3, and the outer diameter is set to the outer diameter of the connecting rod 4 between the spirals 5, 6. of a pair of groove-shaped holders 7, 7 which are larger than the diameter and which engage the opposing surfaces of a pair of arms 8, 8, which are arranged on opposite sides of the opposing surfaces of the pair of bands 2, 2. A pair of dowels 9, 9 made of chevron-shaped members are provided on the opposing surfaces, perpendicular to the direction of the armrests 8, 8 and vertically extending, and a fitting recess 10 for the band 2 is provided in the middle of the dowels 9, 9. It is composed of an armrest bracket and a pillar support fitting. The holder 7 is a groove-shaped member into which the arm 8 is fitted, and the holder 7 and the arm 8 have through holes 1 through which the connecting rod 4 is inserted.
1 is drilled. The abutment 9 is formed of a short chevron-shaped member and is integrally welded to the holder 7. The fitting recess 10 is formed by compression using a press. In the figure, 12 indicates a washer 1 for holding the armrest 8 between the holder 7 and the holder 7.
Numeral 3 is a tightening nut screwed into the spirals 5 and 6.

Therefore, the pair of bands 2, 2 are fitted onto the utility pole 14, and the connecting rod 4 is inserted into the through holes 3, 3 with the connecting pieces 1, 1 facing each other. 6,
6, screw the nuts 13, 13 together, and
3 and 13 to pass through the same spirals 6 and 6, and slide the small outer diameter portion 4' of the connecting rod 4 to form the middle spirals 5 and 13.
5 and the same spiral 5, 5 the same nut 13,13
are screwed together, and the opposing connecting pieces 1, 1 are tightened from both sides in a direction toward each other, thereby tightening and fixing the bands 2, 2 to the telephone pole 14. Next, the both end spirals 6, 6 are inserted into the through hole 11 of the holder 7 and arm 8, and
A nut 13 is screwed onto the spiral 6 protruding outwardly through a washer 12, and the nut 13 is rotated to tighten the pair of arms 8, 8 toward each other, as shown in FIG. The band 2 is fitted into the recess 10 of the dowels 9, 9, and the tops of the dowels 9, 9 are crimped to the sides of the utility pole 14, thereby attaching the pair of arms 8, 8 to the utility pole 14. finish.

Since the present invention is constructed as described above, when tightening the bands 2, 2 to the telephone pole 14, the nuts 13, 13 are screwed into the spirals 6, 6 at both ends of the connecting rod 4 and rotated. When the nuts 13, 13 are removed, the small outer diameter portion 4' reaches the middle spirals 5, 5.
The nut 13 can be slid quickly, and the tightening and fixing work of the bands 2, 2 can be performed quickly and easily, which not only improves the efficiency of the armrest attachment work, but also allows the band 2 to fit into the recess 10. In order to
There is an advantage that the arms 8, 8 can be supported safely and firmly by being crimped onto the side of the utility pole 14.
