Description

  The present invention relates to a wiring duct unit that attaches a wiring duct that supplies power to, for example, a lighting fixture that is an electrical load.

  For example, when attaching the lighting fixture to the ceiling surface, the connector portion of the hooking ceiling cap of the lighting fixture is attached to the connector portion of the hooking ceiling provided on the ceiling surface. Moreover, the mounting plate for attaching a lighting fixture to a ceiling surface is provided, and a lighting fixture is attached to this mounting plate.

  In this case, at least one rising protrusion is provided along the outer periphery of the mounting plate fixed to the ceiling so that the lighting device can be easily attached to the mounting plate, and the recessed portion that engages with the rising projection is connected to the lighting device. There is one provided on the periphery of the mounting bracket (for example, see Patent Document 1).

  FIG. 7 is an explanatory view of the installation of such a lighting fixture. A long screw 12 is attached downward to the mounting plate 11 fixed to the ceiling surface. The long screw 12 passes through a through hole 14 of a mounting bracket 13 connected to a lighting fixture and is attached with a decorative nut 15. Fastened and attached. At this time, a rising projection 16 is provided on the mounting plate 11 so that the long screw 12 can easily pass through the through hole 14, and the rising projection 16 engages with the recess 17 of the mounting bracket 13. When positioned, the long screw 12 passes through the through hole 14.

  In addition, there is a type in which a wiring duct is attached to the ceiling surface, a lighting fixture is electrically connected to the wiring duct, and the lighting fixture is mechanically suspended to freely change the connection angle of the lighting fixture. (For example, refer to Patent Document 2).

FIG. 8 is an explanatory diagram of attachment of the wiring duct 18 to the ceiling surface. A long screw 12 is attached downward to the main body mounting bracket 19 attached to the ceiling surface. The long screw 12 passes through the through hole of the mounting support 20 fixed to the wiring duct 18 and is used as a decorative nut. 15 is attached by tightening. Then, the lighting fixture is mounted by electrically connecting the lighting fixture to the wiring duct 18 and mechanically hanging the lighting fixture.
