[Detailed description of the invention] "Industrial application field" This invention relates to a device for fixing arm rods to utility poles, etc.
The purpose is to provide a fixing device that is lightweight and simple in structure, yet can be extremely firmly fixed to a column.

"Conventional technology" Conventionally, this type of fixing device was
Publication No. 1816, Publication No. 35-12052, Publication No. 12052, Publication No. 12052, Publication No. 12052,
Various techniques have been disclosed in Publication No. 38-17061, Publication No. 16350 of Utility Model Publication No. 45-1970, and the like. However, in these conventional techniques, this is an important element required for this type of fixation device. In terms of how firmly the arm rod can be fixed to poles such as utility poles, it has not always been possible to obtain one that fully satisfies this requirement.

"Problems to be Solved by the Invention" However, as mentioned above, the conventional technology has the problem that the arm rod cannot be firmly fixed as a fixing device.

The present invention was devised in view of these conventional problems, and aims to provide an arm rod fixing device that can fix an arm rod to a column much more firmly than conventional products.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is to use a tightening band attached to one side of the column and a stopper attached to the other side of the column. In a fixing device consisting of a metal fitting and connecting metal fittings provided at both ends of the tightening band, the upper and lower overhanging pieces fixed to the connecting metal fittings are provided with elongated latching holes in the transverse direction of the column. A U-shaped bolt that is hooked into the long latching hole, a fitting that is guided by the U-shaped bolt, and an arm rod that is attached to the back of the fitting and between the arm rod receiving part and the U-shaped bolt. is fixed with a fixing nut via a holding member that fits into the U-shaped bolt, and at least one of the abutment surfaces of the tightening band, stopper fitting, and connecting fitting contact the column. An anti-slip material is pasted on the surface, and in the length direction of the column A of the connecting fitting,
A column characterized in that it is made of the above-mentioned connecting fitting, and has several long engagement holes drilled at appropriate locations, and holes for screwing in small screws for fixing the tightening band that engage with the engagement holes. It consists in the arm rod fixation device.

``Function'' Therefore, an anti-slip material is pasted on at least one of the contact surfaces of the tightening band, stopper fittings, and connecting fittings that come into contact with metal utility poles, etc., and tightened according to the diameter of the pole. The end face of the connecting metal fitting is locked to the end locking portion of the end face of the band, and the band and the connecting metal fitting are connected with a small fixing screw.

Next, tighten the nut, place the metal fitting against the pillar, and fix it to the pillar while pulling the tightening band.
Thereafter, the arm rod is placed, and the arm rod is firmly fixed to the column together with the stopper by means of a fixing nut via a presser member.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

U-shaped connecting fittings 2, 2 are provided at both ends thereof. The connecting fitting 2 includes engagement holes 3, 3 which are elongated in the length direction of the column A, and fixing machine screw holes 4,
4... is formed. Then, the locking part 6 at the end of the tightening band 1 is locked to the tip of the connecting fitting 2 or the above-mentioned engagement holes 3, and the fixing machine screw 5 is screwed into the screw hole 4. As a result, the tightening band 1 and the connecting fitting 2 are connected. Further, the upper and lower overhanging pieces 7, 7 forming the U-shape of the connecting fitting 2 are formed with long holes 8, 8 that extend substantially along the outer surface of the column A, into which a U-shaped bolt 9 is latched. ing.

Reference numeral 10 denotes a fitting fitting arranged on the other side of the column A, and arm rod receiving parts 12 protrude outward from both ends of the abutting part 11, and the abutting part 11 is arranged as shown in FIGS. Then, leave the left and right parts and cut the top, bottom and center part.
Bend this center part left and right, weld the left half to the left side wall and the right half to the right side wall, and attach the arm rod receiver part 1.
2 is formed as a reinforcing piece 13. Further, a parallel seat piece 14 having a through hole 14a and a plate-like seat piece 15 having a through hole 15a are fixedly attached to the arm rod receiving parts 12, 12 in a state that extends laterally. One leg of the U-shaped bolts 9, 9 is inserted into the through hole 14a and the through hole 15a, respectively, and the nut 1 is inserted into the through hole 14a and through hole 15a.
6 allows the stopper fitting 10 to come into contact with the pillar A. 17 is an arm rod, arm rod receiving parts 12, 12
The boat-shaped holding member 18, which is fitted into the notches 12a, 12a of the U-shaped bolt 9, is inserted between the parallel legs of the U-shaped bolt 9, and is straddled between the parallel legs of the fixing nut 1.
It is fixed to the stopper fitting 10 by pressing with 9.

On the other hand, an anti-slip material 20 made of rubber, soft plastic, glass fiber, cotton cloth, metal powder, etc. is attached to the contact surfaces of the tightening band 1, connecting fitting 2, and stopper fitting 10 to the pillar A. ing. Reference numeral 21 denotes a cuff arm rod, which is fixed to the column A via a U-shaped bolt 22 and a cuff 23 arranged on the opposite side of the U-shaped bolt 9.

When fixing the arm rod 17, the tightening band 1 and the connecting fitting 2 are matched to the diameter of the column A and then connected. If the diameter is small, the locking part 6 is locked to the end of the connecting fitting 2 as shown in Figures 2 and 3, but if the diameter is large, it is drilled in the appropriate position as shown in Figure 4. 2. The screws are engaged with the engaged holes 3 that have been inserted. Next, the nut 16 is tightened, the stopper fitting 10 is applied to the column A, and the tightening band 1 is fixed to the column A while being pulled. Thereafter, the arm rod 17 is arranged, and the arm rod 17 is firmly fixed to the pillar A together with the stopper fitting 10 by means of a fixing nut 19 via the presser member 18. If it becomes necessary to add a holding arm rod 21, as shown in FIG.

to be fixed.

Next, the effect will be explained.

In the proposed fixing device configured in this way, as shown in FIGS. 3 and 4, the locking portion 6 of the bent end of the tightening band 1 is
To easily change the connection position according to the size of the pillar A by simply hooking and engaging the end of the connection fitting 2 or the engagement hole 3, and screwing the fixing machine screw 5 into the screw hole 4. At the same time, when force is applied to the tightening band 1, the tightening band 1 is prevented from floating and fixed. If it becomes necessary to add a holding arm rod 21 in addition to the arm rod 17, use the opposite side of the long latching hole 8 that is already used for fixing the arm rod 17 to insert the U-shaped bolt 22. The holding arm rod 21 can be fixed only by tightening.

"Effects of the invention" According to the device for fixing an arm rod to a column according to the present invention, anti-slip materials are provided on the contact surfaces of the tightening band, connecting fittings, and stopper fittings to the column, so that it is possible to tighten the arm rod to the column. Compared to the case where the fixing force is directly tightened with a metal material, the fixing strength of the copper pipe column is increased by approximately three times. In addition, the fittings are cut at the top, bottom, and center, leaving the left and right sides, and the center parts are bent toward the left and right to form large openings, making them wider than conventional ones without openings. Pillar A will be tightened with two narrow bands.
Therefore, even if the surface is sloped up and down, such as a wooden pole A with many uneven surfaces, or a narrow top part of the pillar A like a panzer mast, it is better than a wide single-piece tightening band. It is better to have an opening in the middle and tighten it with two narrow bands, upper and lower, for better adhesion to the pillar. Since the tip of the bent portion described above is fixed to the back surface of the metal fitting to serve as a reinforcing piece, the rigidity of the metal fitting is increased and materials are saved. Another advantage is that the armrest can be fixed simply by inserting a separately provided U-shaped bolt into the long latching hole and tightening it.
