Description

[Detailed description of the invention] This invention is a pole with electrical equipment such as lighting equipment and sirens installed on the top, making it easy to perform maintenance inspections such as repairing paint and repairing electrical equipment, and easy to install electrical equipment. This is about a collapsible pole.

Conventionally, as this type of collapsible pole, the collapsible outdoor lighting pole has a base portoi as shown in Figure 1.

The base opening fixed with A and the bottom plate 2 fixed to the lower end of the lighting column C are rotatably connected with a hinge E, and the bottom plate 2 is fixed by screwing the base port, Ihenat, and G. When this collapsible outdoor lighting pole is installed in a place with a lot of cars and foot traffic, such as on the side of a highway or street, the vibrations caused by cars passing by will cause the base port to collapse.

The nuts and bolts that are fixing the parts may become loose over a long period of time, or the lighting pole may shake due to the wind, and the vibrations may act on the nuts and parts, causing them to loosen.
As a result, there was a risk that the lighting pillar Ha would fall.

Also, in order to install the ballast for the electric light on the lighting pole, the second
As shown in the figure, it was difficult to install the ballast because the ballast had to be installed by removing the cover that covered part of the light pole.

The present invention was developed in view of the above points, and its purpose is to prevent screws from loosening due to vibrations caused by automobiles or wind even after long-term use, and to prevent installation of ballasts, wiring, etc. This provides an easily collapsible pole.

The collapsible pole will be explained below based on FIGS. 3 to 6 showing one embodiment of the present invention. In the figure, 1 is the base of the pole, and the lower part is buried underground and fixed with concrete 2. There is.

Two plate-shaped support plates 3, 3 are juxtaposed and protrude from the upper end, and holes 3a, 3b are bored on the left and right sides of the support plates 3, 3.

Reference numeral 4 denotes a pole body, and a lighting fixture 6 is attached to the tip of a hollow pole 5, and an instrument accommodating portion 7 having a substantially X-shaped cross section is integrally fitted and fixed to the lower end.

The instrument accommodating portion 7 is an elongated body with a substantially X-shaped cross section, and its upper portion is configured to be small enough to fit into the inner surface of the pole 5, and its lower end corresponds to the holes 3a and 3b of the support plates 3, 3. hole 8
A projecting tongue 8.8 with a, 8b is provided in one piece.

Furthermore, a hook 10 for attaching the stabilizer 9 and a switch fixing base 1
1. It is installed integrally in each moon section.

Then, the holes 3a and 3b of the support plate 3 are aligned with the holes 8a and 8b of the protruding tongue pieces 8 and 8 of the pole body 4, and the rotation pin 12 is inserted into one of them so that the pole body 4 can be raised and lowered freely. They are rotatably connected, and fixing pins 13 are inserted through the other holes 3b, 3b and holes 8b, 8b to prevent the pole body 4 from falling.

Reference numeral 14 denotes a cover, which is integrally formed with a trapezoidal part 14a on the upper side, which is penetrated by the pole 5, and a pipe part 14b on the lower side, so that it can be slid up and down, and the cover is shown in FIG. When lowered to the lower end, at least the fixing pin 13 has an inner diameter that hits the inner surface of the cover 14 and prevents it from coming out even if it tries to come out.

The cover 14 is fixed to the pole body 4 with screws 15.

To collapse this collapsible pole, remove the fixing screws 15 of the cover 14 from the pole body 4, pull up the cover 14, and then remove the fixing pin 13, as shown in FIG. Then, the pole body 4 is tilted down by the hinge action of the rotation pin 12.

In addition, when installing the stabilizer, use the rotating pin 12 and the fixing pin 1.
3 is attached to the support plate 3 and the protruding tongue piece 8, the bar 14 is
The device is to be pulled upward and then hooked onto the hook 10 to be fixed.

As described above, the present invention corresponds to a pole base 1 in which support plates 3 are provided in parallel with holes 3a and 3B drilled on the left and right sides of the plate body and protrude toward the upper end, and holes 3A and 3B in the support plates 3. hole 8
A pole main body 4 having an approximately X-shaped cross section provided with protruding tongues 8 and 8 having protruding tongues 8 and 8 B at the lower end of the pole 5; A pivot pin 12 is inserted into the hole 3a of the support plate 3 and the hole 8a of the protruding tongue piece 8 to connect the pole main body 4 so as to be able to freely raise and lower the pole body 4. A fixing pin 13 is inserted into the hole 3b of No. 3 and the hole 8b of the protruding tongue piece 8.
is inserted through the pole body 4 to be fixed to the pole base 1, and the cover 14 covers the instrument storage part 7, and the fixing pin 13 is prevented from coming out on the inner surface of the cover 14. As a result, even if vibrations from a car etc. are applied, the fixing pins will hit the inner surface of the cover and will not come out, so there is no risk of it falling over even when used for a long time, and when the cover is pulled up, the ballast can be attached. Since the parts are exposed, wiring and installation are easy.

Furthermore, since the instrument accommodating part has an X-shaped cross section and is separated into interchambers, there is an electrical effect that there will be no mutual interference such as magnetism when 2 to 4 ballasts are installed in each room. It is something that you have.
