Description

[Detailed description of the invention] The present invention relates to a mounting structure for attaching a hook ceiling for a separate power supply to a lighting equipment, and does not require any tools to install the hook ceiling. The purpose is to ensure that it can be installed without coming off.

In order to attach a hook ceiling for a separate power source to a lighting fixture to supply power to another electrical appliance, conventionally, as shown in FIG.
is fastened to the main body 4 of the lighting fixture with screws 3.

Therefore, a tool such as a screwdriver is required for installation, and if the screws 3 are not tightened sufficiently, they may rattle or come off.

The present invention provides a mounting structure in which a hook ceiling stand 2 can be securely attached to a lighting fixture body 4 without the need for tools, and there is no fear that the hook ceiling stand 2 will come off.

FIG. 2 shows a side sectional view of an embodiment of the present invention.

In the figure, reference numeral 4 denotes a lighting equipment main body consisting of a top plate 4' and a mounting plate 6, which is installed by being hooked onto an embedded hooking rosette 5 provided on the ceiling surface. The bases of the arms 7 are sandwiched and fixed with screws shown in the figure, and a lamp 8 having a lamp 9 is attached to the tip of each arm 7.

These lamps 9 are connected to a power source by a hook ceiling 10 inserted into the hook rosette 5.

A hook ceiling 1 for a separate power supply is attached to the mounting plate 6 on the lower side of the main body 4 by a hook ceiling holder 2, and the lighting equipment main body 4 and the hook ceiling holder 2 are attached to the hook ceiling holder 2.
A cover 11 covering the is secured with thumbscrews 12.

FIG. 3 shows an enlarged cross-sectional view of the part where the hanging ceiling stand 2 is attached to the lighting fixture main body 4, and FIG. 4 shows a perspective view of the main parts thereof.

The hook ceiling jig 2 to which the hook ceiling 1 for a separate power supply is fixed has a U-shape, and one end thereof is rotatably attached to the mounting plate 6 on the lower side of the main body 4 around a shaft 13, and the other end is attached to the outside. A hole 15 is provided in the bent portion 14.

Furthermore, an L-shaped hook 16 is provided on the lower surface of the mounting plate 6 of the main body 4.

To attach the hanging ceiling stand 2 to the lighting fixture body 4,
As shown in FIG. 5, the hook sealing stand 2 is rotated around the shaft 13, the bent end 14 is pulled outward, the hole 15 is engaged with the hook 16, and then the cover 11 is fitted. , the cover 11 is screwed and fixed to the hook sealing stand 2 with the thumbscrews 12.

At this time, the distance between the inner wall surface of the cover 11 and the tip 14' of the bent portion 14 of the hooking sealing stand 2 is set to the outer edge of the hole 15 provided in the bent portion 14 and the tip of the hooking claw 16. If the distance a is made smaller than the distance a between the cover 11
After being fixed to the hook sealing base 2, the deformation movement of the hook ceiling base 2 is regulated by the cover 11, and the hook ceiling base 2 will not come off from the hook claw 16.

As described above, in the present invention, one end of the hook ceiling base to which the hook ceiling for a separate power supply is fixed is rotatably attached to the bottom surface of the lighting fixture body, and the other end is an L-shaped hook provided on the bottom surface of the lighting fixture body. Attach the ceiling ceiling base to the lighting fixture body, and screw the cover covering the lighting fixture body and the ceiling ceiling fixture to the ceiling ceiling fixture, and use this cover to prevent deformation, movement, etc. of the ceiling ceiling fixture. This prevents the ceiling hook from coming off the hook, and no tools are required when installing the ceiling ceiling, and there is no risk of the ceiling ceiling coming off after the cover is attached. Installation is easy and reliable.
