Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a traffic light mounting device suitable for mounting road traffic signals, particularly pedestrian traffic lights.

BACKGROUND OF THE INVENTION Currently, pedestrian traffic signals for road traffic are often mounted with a pair of L-shaped arms 51 and 52 supporting the signal 50 from above and below, as shown in FIG.

Problems to be solved by the invention On the other hand, pedestrian traffic lights are installed at relatively low positions so that pedestrians can easily visually confirm the signals. For this reason, the traffic light 5
Vehicles and other objects collide with the L-shaped arm 52 that supports the 0 from below, which not only causes the inconvenience of distorting the traffic light, but also causes personal injury.

The present invention was devised in view of these circumstances.The present invention is designed to support the traffic signal in a suspended state, eliminating the lower support arm of the conventional device, eliminating the above-mentioned inconvenience caused by the support arm, and reducing the installation work. To provide a traffic light mounting device which can be easily carried out, has a sturdy support structure, can sufficiently withstand strong winds, etc., and has an excellent appearance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the drawings.

Fig. 1 shows the usage state of the traffic light installation device according to the present invention, in which 1 is a cylindrical body formed into an inverted L shape by bending a metal pipe, and 2 is a vertical arm.
A horizontal arm 4 is connected to the upper end of the horizontal arm 4 through an arc-shaped curved part 3.
are installed in succession. The free end of the horizontal arm 4 is beveled and sealed with a cover plate 5. Openings 6, 6, which are diametrically opposed to each other and pass through in the vertical direction, are bored near the free end (see FIGS. 2 and 4).

The vertical arm 2 is provided with a plurality of fittings 7 for attaching to the column 8, and a band 9 wrapped around the column 8 is tightened and fixed by the fittings 7 to attach the main body 1.
It is the same as the conventional device in that it is attached and fixed to the support column 8.

Reference numeral 10 denotes a hanging fitting for the traffic light 50, which has a hollow shaft 11 that is inserted into the openings 6, 6 provided in the horizontal arm 4, as clearly shown in FIGS. 2 and 3.
Male threads 12 and 13 are provided on the outer periphery of both ends of the hollow shaft 11.
is provided. A lower receiving seat 14 having a curved seat 15 along the lower arc of the horizontal arm 4 is fitted into the middle portion of the hollow shaft 11 and fixed by welding 16 . In addition, the hollow shaft 11 has a lower receiving seat 14.
A through hole 17 that communicates with the inner hole 4a of the horizontal arm 4 when attached to the horizontal arm 4 is provided on the upper side.

Reference numeral 18 denotes an upper receiving seat, which has a curved seat 19 along the upper arc of the horizontal arm 4, is loosely fitted onto the hollow shaft 11, and is disposed opposite to the lower receiving seat 14.

A receiving seat tightening nut 20 tightens and fixes the upper receiving seat 18, and is configured as a cap nut to be screwed onto the male screw 12 of the hollow shaft 11 and to seal the upper end opening of the hollow hole 11a.

Reference numerals 21 and 22 denote suspension tightening nuts, which are respectively screwed onto the male screw 13 of the hollow shaft 11 through washers 23 and 24, facing each other;
A seal packing 25 is interposed between them.

All of the tightening nuts 20 to 22 are double-nut locking nuts as described in, for example, Japanese Utility Model Publication No. 50-36123. That is, it is a locking nut having a structure in which a truncated conical protrusion 28 and a recess 29 are provided on the opposing surfaces of the pair of nuts 26 and 27, and the protrusion 28 and the recess 29 are slightly eccentric. By using such a locking nut, the support structure of the traffic light 50 becomes strong and reliable. However, it is also possible to use other nuts.

Next, the installation order of the pedestrian traffic light 50 using the installation device having the above structure will be explained.

First, as shown in FIG. 1, the vertical arm 2 of the cylindrical body 1 is connected to the band 9 attached to the support column 8 using the mounting bracket 7, and is attached and fixed.

Next, the hollow shaft 11 is inserted into the openings 6, 6 of the horizontal arm 4.
from below to press the lower receiving seat 14 against the lower surface of the horizontal arm 4. At this time, a seal packing 31 is interposed between the curved seat 15 and the horizontal arm 4 to seal the opening 6. Further, the wiring cords 35 and 36 (see FIG. 2) of the traffic light 50 are inserted into the hollow hole 11a from the lower end opening of the hollow shaft 11 and introduced into the inner hole 4a of the horizontal arm 4 through the through hole 17, and the It is pulled out from the lower end opening and connected to a power cord (not shown) provided on the support column 8. In addition,
As shown in FIG. 4, a small through hole 33 is provided in the middle of the horizontal arm 4, and a wiring cord for an audio transmitter, etc. that converts the signal of the traffic light 50 into audio and transmits it is pulled out through this through hole 33. Sometimes. In the figure, 34 is a bushing that seals the through hole 33.

After wiring the cords 35 and 36 as described above, the upper receiving seat 18 is fitted to the upper protrusion of the hollow shaft 11 via the seal packing 32, and then the tightening nut 20 is screwed onto the male thread 12. tightening,
The hollow shaft 11 is fixed to the horizontal arm 4 by sandwiching the horizontal arm 4 between the upper receiving seat 18 and the lower receiving seat 14 from above and below.

Next, screw the upper hanging tightening nut 21 onto the male screw 13, and then tighten the washer 23 and seal packing 2.
5 is fitted, an opening 54 is formed in the top plate 53 of the main body case of the traffic light 50 at the lower end portion of the hollow shaft 11.
In the state where they are fitted together, fit the washer 24 onto the hollow shaft 11 from the inside of the top plate 53, screw the lower suspension tightening nut 22 onto the male screw 13, and tighten the top with both nuts 21 and 22. The plate 53 is sandwiched and fixed. As a result, the traffic light 50 is
It is attached and supported in a suspended state on the horizontal arm 4 via.

Effects of the Invention As described above, according to the present invention, the traffic light 50 is attached to the horizontal arm 4 in a suspended state via the hanging fitting 10, and the arm that supports the traffic light from below can be omitted. Furthermore, the support structure formed by the hanging fittings 10 is robust and strong, and can withstand strong winds. Furthermore, the installation work using the hanging fitting 10 is very simple, and can be easily and quickly installed by one worker, resulting in labor savings. Furthermore, since the cord of the traffic light 50 can be housed and wired in the hollow hole 11a of the hollow shaft 11 of the hanging bracket 10 and the inner hole 4a of the horizontal arm 4, the cord is not exposed to the outside and the appearance is excellent. .
