Description

[Detailed Description of the Invention] (Industrial Application Field) 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 usually has a pair of parallel side channels. It is constructed so that it is attached to the ceiling frame using mounting brackets, and this side channel supports sockets, reflectors, stabilizers, etc.

By the way, in this type of device, when a space is required to attach a louver, panel, etc. (hereinafter simply referred to as a louver) to the lower part of the lower open surface of the reflector, the lighting equipment is placed at a position above and below the side channel. Selective installation is required.
Conventionally, two types of mounting brackets are prepared and used selectively, but 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 for the installation of louvers, etc. between the open surface of the reflector and the lower surface of the ceiling frame in lighting equipment that is installed on the ceiling frame using a side channel. When installing the side channel at a higher position to secure space for The purpose is to enable installation.

(Means for solving the problem) This invention fixes the engaging leg to the back of the support fitting that is attached so as to enclose the side channel, and also allows the lower end to be placed on the upper surface of the ceiling frame. A slit is formed in the vertical direction of the mounting bracket, and first and second step portions are provided at the lower and upper portions of the slit, with which the engaging leg inserted through the slit selectively engages. It is characterized by

(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, a U-shaped engagement leg 11 made of a spring material is fixed to the back side of a support metal fitting 10 attached so as to surround the side channel 3.

Further, a slit 13 is formed in the mounting bracket 12 whose lower end can be freely placed on the upper surface 1A of the ceiling frame 1 along the vertical direction thereof. The slit 13 is provided with first and second stepped portions 14 and 15 with which the engaging leg 11 inserted therein selectively engages at its lower and upper portions.

Between the step portions 14 and 15, the distance between the slits 13 becomes narrower toward the top. That is, both side edges of the slits 13 are tapered so that the distance between the slits 13 becomes narrower from the stepped portion 14 to the stepped portion 15.

In the above configuration, first, the first step portion 14 at the bottom of the slit 13 is made to have an engaging leg. Then, the lower end of the mounting bracket 12 is placed on the upper surface 1A of the ceiling frame 1. Then, the claw 19 provided at the lower end of the mounting bracket 12 is bent to engage with the back surface of the upper surface 1A of the ceiling frame 1, and the mounting bracket 12 is attached to the ceiling frame 1. As a result, the open lower end surface of the reflector plate 7 and the lower surface 1B of the ceiling frame 1 are installed so as to be substantially flush with each other.

Next, when it becomes necessary to attach the louver 17 to the lower part of the open surface of the reflecting plate 7, the support fitting 10 and the side channel 3 can be pushed up together with the mounting fitting 12. Then, the engaging leg 11 rises within the slit 13 and is narrowed by the taper of the slit 13 in the process, but when it reaches the second step 15 it expands and engages with the step 12. become.

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 explanation, the distance between the stepped portions 14 and 15 of the mounting bracket 12 is equal to the distance between the louver 17
The height is comparable to that of the installation space. Therefore, the distance may be set depending on the height of the louver 17 to be installed.

Further, if a leg 18 with a bent tip as shown in the figure is provided on the back of the support fitting 10, and the mounting fitting 12 is held between the leg 18 and the engagement leg 11, the fitting will be firmly engaged. It's convenient now.

Further, the support fitting 10 is slidable along the side channel 3. By doing this, even if the support fitting 10 matches the position of the bolt that hangs the ceiling frame 1, if you can slide it and move it from that position, you can use the bolt does not pose any hindrance.

(Effects of the invention) As detailed above, according to this invention, a lighting fixture can be installed from a lower position to an upper position by simply pushing up a type of support metal fitting together with a side channel. be effective.
