Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a lighting equipment device used in a ceiling system or the like.

(Prior Art) As is well known, this type of lighting device is installed using a ceiling frame (T-bar) attached to the ceiling, and a pair of parallel side channels are prepared and installed. Attach to the ceiling frame using metal fittings, and attach sockets, reflectors,
It is configured to support a stabilizer, etc.

In this case, the lower end open surface of the reflector is installed on almost the same plane as the lower surface of the ceiling frame to improve the appearance. However, depending on the type of lighting equipment, it may be required to install a louver, panel, etc. (hereinafter simply referred to as a louver) on the lower surface of the reflector.
However, if the louver is simply attached to the lower part of the open surface of the reflector, the louver will protrude below the lower surface of the ceiling frame, resulting in an unsightly appearance.

To solve this problem, install the side channel higher than before and raise the lighting fixture itself to create a space between the open surface of the reflector and the bottom surface of the ceiling frame where the louver can be installed. Just do it.

However, in order to install the side channel at such a high position, it is necessary to use a different mounting bracket to support it on the ceiling frame. For this purpose, at least two types of mounting brackets with different shapes must be prepared. Preparing a plurality of mounting brackets in this way is extremely troublesome, and there is also a risk that they may be lost.

(Problem to be solved by the invention) This invention is a lighting fixture that is installed in a ceiling frame using a side channel. When installing the side channel at a higher position to ensure that The purpose is to do so.

(Means for solving the problem) This invention consists of a support metal fitting with a U-shaped cross section that is attached to surround the side channel, and a support metal fitting that is rotatably attached to the support metal fitting. A first mounting bracket that rests on the upper surface of the ceiling frame is located on the periphery of the mounting bracket at different distances from the center of rotation of the mounting bracket.
and a second bent edge, and both bent edges can be selectively placed on the upper surface of the ceiling frame by rotating the mounting fittings.

(Example) An example of this invention will be described with reference to the drawings. 1 is a ceiling frame, which is fixed so that it hangs from the ceiling. Reference numeral 2 denotes a lighting fixture, which has a pair of parallel side channels 3, on which a socket base 4, a socket 5, a ballast part 6, a reflector plate 7, etc. are supported. The reflector plate 7 is attached to the support portion 8 with decorative screws 9.

The above configuration is not particularly different from ordinary devices of this type. According to this invention, the side channel 3 is attached so as to enclose it.
The device includes a support metal fitting 10 having a U-shaped cross section, and a mounting metal fitting 12 rotatably attached to the support metal fitting 10 with a rivet 11.

On the peripheral edge of this mounting bracket 12, first and second bent edges 13, 14 resting on the upper surface 1A of the ceiling frame 1 are formed on side edges and end edges that are separated by different distances from the center of rotation by the rivet 11. Form it. Note that 15 and 16 are convex portions that fit into round holes and screws for positioning the mounting bracket 12.

1, 3, and 9 show each portion when the lower end open surface of the reflector plate 7 and the lower surface 1B of the ceiling frame 1 are installed so as to be substantially on the same plane. At this time, the first bent edge 13 located near the center of rotation of the mounting bracket 12 is placed on the upper surface 1A of the ceiling frame 1.

Next, when it becomes necessary to install the louver 17 at the lower part of the open surface of the reflector plate 7, the mounting bracket 12 is rotated 90 degrees with respect to its previous position. The state at this time is shown in FIGS. 2, 4, and 8.
At this time, the second bent edge 14 located far from the center of rotation of the mounting bracket 12 comes to rest on the upper surface 1A of the ceiling frame 1.

At this time, the side channel 3 will be installed at a higher position than before, so the louver 17 will be placed between the reflector 7 and the lower surface 1B of the ceiling frame 1.
A space will be secured for the installation.

As understood from the above description, the difference in the vertical distance from the rotation center of the mounting bracket 12 to the first and second bent edges 13, 14 is comparable to the height of the installation space of the louver 17. . Therefore, the difference in the vertical distance may be set depending on the height of the louver 17 to be installed.

Note that claws 18 and 19 are formed near the bent edges 13 and 14 of the mounting bracket 12. This is because when each bent edge is placed on the top surface 1A of the ceiling frame 1, the claws are bent to engage the back surface of the top surface 1A of the ceiling frame 1, thereby preventing the entire lighting fixture from lifting up. ing.

Further, the support fitting 10 is slidable along the side channel 3. 20 is its guide claw. This means that even if the support fitting 10 matches the position of the bolt suspending the ceiling frame 1, if it is made slidable, the bolt will not get in the way.

(Effects of the invention) As detailed above, according to this invention, it is now possible to selectively install the reflector in two positions, upper and lower, simply by rotating a type of mounting bracket. Therefore, the effect is that one mounting bracket can be used for installing two reflector plates.
