Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement in the hanging structure of lighting equipment.

[Conventional technology and its problems]

Conventionally, on the ceiling surface of the factory or the ceiling surface of the corridor of the building, for example, in Fig. 5, at the corresponding position on both sides of the mounting bracket 1 composed of a box shape, 2
3, a hanging metal fitting 4 is engaged between the fitting grooves 2 and 3 on both sides, and a hanging ring 5 is placed in the center of the hanging metal fitting 4.
A structure is implemented in which a hanging pipe 7, which supports a lighting fixture 6, is connected to the lower end of the pipe.

However, according to the same structure, the hanging fitting 4 is engaged between the fitting grooves 2 and 3 on both sides of the mounting fitting 1, and the hanging pipe 7 is supported on the hanging fitting 4 via the hanging ring 5.
Since the lighting fixture 6 is supported, a hanging metal fitting 4 is required, and there is a drawback that supporting the lighting fixture 6 requires a lot of work.

[Purpose of invention]

The present invention has been devised in view of the above points, and an object of the present invention is to provide a hanging structure for a lighting fixture that has a small number of parts and facilitates the work of supporting the lighting fixture.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 4. In the figure, 11 is an L-shaped support piece 1, for example.
2, in which a notch hole 15 is formed extending from the end portion 13 to the inner plane portion 14. Note that the engaging pieces 16 and 17 may be formed from the opposite side to the end portion 13. Reference numerals 16 and 17 denote hooking pieces formed on the upper surfaces of both ends of the cutout hole 15 of the flat part 14 of the fixture 11, and the diameter increases inward, and there is a gap between the inner end and the flat part 14. It is configured with a gap 18 between. Further, the outer ends of the engaging pieces 16 and 17 are configured to be inclined inwardly and upwardly. Reference numeral 19 denotes a hanging pipe having a flange 20 on the outer periphery of its upper end, which penetrates along the upper surfaces of the engaging pieces 16 and 17 and falls onto the flat surface 14 of the mounting bracket 11 at the enlarged diameter portion 21 of the engaging pieces 16 and 17. Then, attach the flange 20 to the engaging pieces 16 and 17.
It is engaged and supported in the gap 18 of. 22 is hanging pipe 1
The lighting fixture 23 supported on the lower end of 9 has a support bolt 24 for supporting the mounting bracket 11 on the mounting surface.
is a flange that has a pipe through hole and covers the mounting fitting 11.

[Effect of invention]

In the above structure, the hanging pipe 19 is inserted from the end of the cutout hole 15 of the mounting bracket 11 supported on the mounting surface of the building along the hooking pieces 16 and 17, and the hanging pieces 16 and 17 are expanded. The flange 20 of the hanging pipe 19 falls onto the flat part 14 of the mounting bracket 11 at the diameter part 21, and after that, the flange 20 is engaged in the gap 18 between the hooking pieces 16, 17 and supported by the hanging pipe 19. The support for the lighting fixture 22 is completed.

[Effects of the invention] As described above, the present invention forms a cutout hole extending from the end of the fixture to the inner plane part, and expands inward on the top surface of both ends of the cutout hole in the same plane part. diameter,
In addition, a hooking piece having a gap between the inner end and the flat part is formed, the hanging pipe is penetrated along the hanging piece, and the flange of the hanging pipe is connected to the flat part of the fixture by the enlarged diameter part of the hanging piece. The structure is such that the flange is hooked and supported in the gap between the hooking pieces, so the number of parts is reduced compared to the conventional structure, and the lighting equipment can be easily supported.
