Description

[Detailed description of the invention] This invention relates to lighting poles that are erected on both sides of a roadway or on a separation strip between roadways.

The lighting pole provided along the roadway is provided with a lamp support arm that projects above the roadway, and a lamp is attached to the end of this support arm for illumination.

By the way, in the case of lighting poles, it is necessary to periodically clean the lamps or replace the light bulbs if they are broken or damaged.

Conventionally, when cleaning light fixtures and replacing light bulbs, a work vehicle with a lift was stopped near the light pole, or if the light pole could be raised and lowered, the light fixture was lowered and the work was done on the ground. There is. However, in either case, the work is done on the roadway, which obstructs traffic and is dangerous.

Therefore, the object of this invention is to solve the above-mentioned problems and provide a lighting pole that allows cleaning of lamps and replacement of light bulbs to be carried out safely without the need for traffic control.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 1 to 4, the column support plate 1 is provided with a plurality of screw holes 2, and the upper part of the anchor bolt 3 is screwed into the lower part of the screw hole 2, and the anchor bolt 3 is inserted into the ground. It is buried in the formed foundation and can be stably attached to, for example, the median strip A shown in FIG. 1.

A lamp support arm 5 is formed horizontally at the upper part of the pillar 4 that stands up from the pillar support plate 1, and a lamp 7 is attached to the end of the arm 5. Further, a circular flange 8 facing the column support plate 1 is provided at the lower part of the column 4, and between this circular flange 8 and the column support plate 1, a plurality of balls 9 supporting the circular flange 8 are arranged in an annular manner. It is set in.

A plurality of rollers 10 arranged around the outer periphery of the circular flange 8 have roller shafts 1 that stand up from the column support plate 1.
1 is rotatably supported. This roller 10 includes a flange 11, and the flange 12
engages with the outer periphery of the upper surface of the circular flange 8 and
prevents it from falling over.

Further, a bolt insertion hole 13 is formed in the circular flange 8 at a position corresponding to the screw hole 2 of the column support plate 1, and a bolt 14 inserted into this bolt insertion hole 13 is formed.
is screwed into the screw hole 2. For this reason,
When the bolt 14 is rotated and tightened, the circular flange 8 moves toward the column support plate 1, and the column 4 can be prevented from rotating.

Now, when the bolt 14 is rotated and removed to release the rotation stopper of the support 4, the flange 1 of the roller 10 will be removed.
2 and the circular flange 8 can hold the column 4 in an upright state, and since the circular flange 8 is supported by a plurality of balls 9, the column 4 cannot be rotated. can.

For this reason, as shown in Figures 1 and 2,
With the lamp support arm 5 protruding above the roadway, by rotating the support 4 and making the upper lamp support arm 5 parallel to the roadway, the lamps can be cleaned along the roadway, such as in the median strip or sidewalk. You can perform tasks such as changing lights and changing light bulbs.

BACKGROUND ART Conventionally, there are lighting poles of the elevating type in which the light is raised and lowered using a winding device provided inside the pole, and the tilting type in which the lower part of the pole is bendable. Therefore, in order to clean the lamps and replace the light bulbs on these lighting poles, if the lamp is of the lifting type, it is necessary to rotate the pillar so that the lamp support arm is parallel to the roadway, and then lower the lamp. In the ceremony, the column is rotated in the same way as above to make the lamp support arm parallel to the roadway, and then the column is bent.

In the embodiment, the rotatably supported column is directly rotated manually, but it is also possible to rotate it by employing a worm, a worm wheel, or the like.

After completing work such as cleaning the lamp and replacing light bulbs, rotate the support post 4 so that the lamp support arm 5 extends above the roadway, and then insert the bolt 14 into the bolt insertion hole 13 of the circular flange 8. This is then screwed into the screw hole 2 of the support plate 1 for tightening work.

Note that by forming the bolt insertion hole 13 as an arc-shaped elongated hole centered on the support 4, alignment of the bolt insertion hole 13 and the screw hole 2 is easy, and the directional position of the lamp support arm 5 can be finely adjusted. be able to.

In the embodiment shown in FIGS. 3 and 4, the flange 12 of the roller 10 is engaged with the outer circumference of the upper surface of the circular flange 8, but as shown in FIG. It is also possible to support a roller shaft 11 arranged horizontally, and to engage the lower part of the outer circumference of the roller 10 fitted on the outside of this roller shaft 11 with the outer circumference of the upper surface of the circular flange 8.

As described above, this idea allows the support pillar to rotate freely relative to the support plate attached to the median strip, sidewalk, etc., so the orientation of the lamp support arm can be changed by rotating the support, and the support for the lamp can be changed. By placing the arm parallel to the roadway, it is possible to clean the lamps on the poles and replace the light bulbs along the road, and the work can be done safely.

In addition, the pillar support structure has extremely low rotational resistance, in which a circular flange formed at the bottom of the pillar is supported by multiple balls, and a rotatable roller is engaged with the outer periphery of the upper surface of the circular flange. It can be rotated with a light force, the support is stable, and there is no inconvenience that the support will fall when changing the direction of the lamp support arm.

Furthermore, the circular flange is connected to the column support plate by tightening the bolt screwed into the screw hole of the column support plate, and the column is prevented from rotating, so it is easy to prevent and release the rotation of the column, and it is easy to clean the lamp and light bulb. The replacement work can be carried out efficiently.

In addition, since it has a simple configuration with a small number of parts, it is easy to assemble.
