2. Description of the Related Art A thin luminaire to be installed almost in close contact with a ceiling surface or a wall surface is troublesome in construction because it is necessary to screw a mounting plate of the luminaire to a reinforcing material provided on the ceiling or the wall. In addition, there is a restriction that connecting the power line cannot be done without qualification because of legal restrictions. Also, if it can be installed using a hook ceiling outlet that has been installed in advance on the ceiling surface, etc., the construction will be simple, but there are two standards for hook ceiling outlets.
Since the distance from the ceiling surface to the outlet mounting surface is different between the thick rectangular shape and the thin circular shape called a public corporation, an auxiliary member is required to correct this difference. Further, there is a problem in that it is difficult to rotate the lighting fixture of the top surface close-attached type after it is mounted in order to mount it so that there is almost no gap between it and the ceiling surface.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to connect a thick type and a thin type hooking ceiling outlet to a lighting fixture of a top surface close-attached type with a ceiling surface and the like. It is an object of the present invention to provide a lighting fixture mounting device that can be easily mounted so that there is almost no gap between them and that can be rotated and finely adjusted after mounting.

[0004]

In order to achieve the above-mentioned object, a lighting fixture mounting device of the present invention has a plug portion having a hook ceiling plug for engaging with a hook ceiling outlet on the upper surface, and at least two sets outside. Of side surfaces parallel to each other and upper and lower supporting portions provided at two positions above and below the side surfaces, respectively, and a rotation supporting portion rotatably supported on the outer periphery of the plug portion in a horizontal plane. Has become.

[0005]

The hooking sealing plug of the lighting fixture mounting device is connected to the hooking ceiling outlet provided on the ceiling surface, etc., and the position of the lighting fixture in the direction of rotation is appropriately determined. When it is pushed up from the bottom so as to coincide with, the holding claw provided in the mounting recess is once retracted and then engaged with the lower stage supporting portion of the lighting fixture mounting device. When the hook ceiling outlet is thin, it is installed in this state so that there is almost no gap between the lighting fixture and the ceiling surface. Also, if the hook ceiling outlet is thick, there is still a gap between the lighting fixture and the ceiling surface, so if you push the lighting fixture further, the holding claws will retract and disengage from the lower support section, and will rise further to the upper stage. It is attached to the support portion so that there is almost no gap between the lighting fixture and the ceiling surface. Since the rotation support part of the lighting fixture mounting device is rotatable with respect to the plug part, finally the lighting fixture is appropriately rotated to accurately position in the rotation direction.
