Description

[Detailed Description of the Invention] The present invention relates to an improvement in the opening/closing mechanism of a road light luminaire.

Conventional opening/closing mechanisms for street lamps have various structures. For example, as shown in FIG.
There is a structure in which a frame body 4 having a glove 3 is provided with a rotating shaft 5 at one end corresponding to the hooking part 2.

By the way, the size of the road light fixture with the above structure varies depending on the size of the light source, but for example,
When installing Watsuto's high-pressure discharge lamp, the standard type is the total length of the lighting fixture, 77 cm in height, 33 cm in height, and the total weight of the lighting fixture is 14 kg.
It is. Of the 14 kg, the weight of the frame 4 and glove 3 is approximately 7 kg.

However, according to the same structure, in order to remove the frame 4 having the globe 3 from the lighting fixture body 1, it is necessary to rotate the frame 4 180 degrees from the attached state as shown in FIG. Because the weight of the frame 4 with the
Further, it is not easy to attach and detach the frame 4 to and from the lighting fixture body 1 at a high place, and there is a drawback that the operation is likely to lack safety.

The present invention was devised in view of the above points, and its purpose is to provide an opening/closing mechanism for a road light luminaire that allows the globe frame to be easily attached and detached from the luminaire body without causing any danger. do.

The present invention will be explained below with reference to FIGS. 3 to 5. In the figure, reference numeral 1 denotes a lighting fixture body, and a curl-shaped hinge receiver 7 having a narrow insertion hole 6 in a part of the upper surface is integrally formed inside one lower end on the support arm attachment side. 4 is a glove frame body,
A hinge rod 8 is provided corresponding to the insertion hole 6 of the hinge receiver 7, and a partial cutout 9 of the hinge rod 8 is formed corresponding to the narrow insertion hole 6.

Furthermore, when the globe frame 4 is positioned at an angle of 15 degrees to 45 degrees with respect to the lighting device main body 1 as shown in FIG.
Remove the hinge rod 8 from the hinge receiver 7 by lifting the notch 9 upward and to the left within the range of 15 degrees to 45 degrees.

If the removal angle of the glove frame 4 is smaller than 15 degrees, it will be difficult to remove the glove frame 4, and
If the diameter is larger than the angle, there is a risk that the glove frame 4 will fall off when rotated. 10 is a socket fixed inside the lighting fixture body 1, 11 is a ballast provided in the hollow part of the lighting fixture body 1, 12 is a capacitor, 13 is a mounting arm for supporting the lighting fixture body 1, and 14 is a globe frame. For example, a glass globe supported by a glass globe.

The size of the road light fixture with the above structure varies depending on the size of the light source, but for example, when a 400 watt high pressure discharge lamp is installed, the total length of the lighting fixture body is 77 cm, as with the conventional structure. Height is 33cm, total weight of lighting equipment is approximately 14Kg
It is. The weight of the glove frame 4 and the glove 14 is approximately 7 kg.

When a 700 watt high pressure discharge lamp is installed, the total length of the lighting fixture body 1 is 94 cm, the height is 42 cm, and the total weight of the lighting fixture is 18 kg. Of the total weight of the lighting equipment of 18 kg, the weight of the glove frame 4 and the glove 14 is about 9 kg.

Next, the attachment and detachment of the frame in the opening/closing mechanism of the road light luminaire described above will be explained. In order to support the above-mentioned road lighting equipment on a pole having a height of, for example, about 15 meters installed at the end of a highway or the like, a worker climbs onto a ladder of a so-called tower car and performs the installation work.

Also, if the glove 14 is cracked or the glove 1
4. For cleaning etc., attach the globe frame 4 to the lighting fixture body 1.
When removing the tower from the tower, the worker climbs onto the ladder of the tower vehicle and performs the work. In the removal work of the glove frame 4, according to the opening/closing mechanism according to the present invention, the glove frame 4 can be removed in the range of 15 degrees to 45 degrees, which is the initial stage of opening the glove frame 4. As shown in the conventional structure, the glove frame 4
There is no need to rotate the unit 180 degrees, making removal work easier. Also, adjust the glove frame 4 from 15 degrees.
Since it can be attached and detached within a range of 45 degrees, even if the worker releases the glove frame 4 with the stopper removed, the centrifugal force of the glove frame 4 is small, and the glove frame 4 is connected to the curled hinge of the lighting fixture body 1. There is no fear that the glove frame 4 will fall off the receiver 7, and the glove frame 4 can be removed safely at a high place.

As mentioned above, the present invention provides a curl-shaped hinge receiver with a narrow insertion hole in a part of the upper surface inside the lower end of the lighting equipment body, and the globe frame is set at an angle of 15 to 45 degrees with respect to the equipment body. Since the hinge rod is configured so that it can be removed from the insertion hole within the range, compared to the conventional structure as described above, there is no need to open the glove wide and remove it, making it easier to attach and detach the glove frame at high places. The glove frame is against the main body.
The glove frame can be removed by pulling it toward you in the range of 15 to 45 degrees, making it possible to safely attach and detach the glove frame, which has great utility value.
