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 usually has a pair of parallel side channels. is attached to the ceiling frame using support metal fittings, and the lighting equipment consisting of a socket, reflector, ballast, etc. is supported on this side channel.

By the way, in this type of device, when 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 side channel is selected to be located above or below the ceiling frame. It is required to install the Conventionally, two types of support metal fittings are prepared and used selectively, but preparing multiple support metal fittings in this way is extremely complicated, and it is necessary to replace and install them each time they are used. Yes, and the work is extremely tedious.

(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 Problems) This invention provides a lighting device in which a side channel is attached to a ceiling frame fixed to the ceiling, and a lighting device is supported on the side channel.
A support fitting is attached so as to surround the side channel, and on both sides of the frame provided on the support fitting,
A mounting bracket has a plurality of holes arranged in a vertical direction, has a base part placed on the surface of the ceiling frame, and is slidable relative to the support bracket; A connecting fitting having a bent portion is fixed to the connecting fitting, and the bent portion of the connecting fitting can be selectively inserted into a hole in a frame portion of the supporting fitting through a hole formed in the mounting fitting. Features.

(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. 2 is a lighting equipment, which has a pair of parallel side channels 3, a socket base 4, a socket 5,
A stabilizer section 6, a reflecting section 7, and the like are supported.

The above configuration is not particularly different from ordinary devices of this type. According to this idea, the support fitting 9 is attached so as to surround the side channel.
This support fitting 9 is provided with a U-shaped frame 10, and a plurality of holes 11 arranged in the vertical direction are formed on both sides of the frame 10.

Further, a mounting bracket 13 is provided which has a base portion 12 placed on the surface 1A of the ceiling frame 1 and is slidable relative to the support bracket 9. That is, this mounting bracket 9 has side walls 14 on both sides.
The side wall 14 functions as a guide for sliding the frame portion 10.

A connecting fitting 16 having bent portions 15 on both sides is fixed to the mounting fitting 13 by rivets 17. Then, the bent portion 15 of this connecting fitting 16 is
It can be selectively inserted into the hole 11 of the frame 10 of the support fitting 9 through the hole 18 formed in the mounting fitting 13.

In the above configuration, as shown in FIGS. 1 and 5, the base portion 12 of the mounting bracket 13 is normally attached to the ceiling frame 1.
is placed on the surface 1A of. In this position, the lower open surface of the reflector 7 and the lower surface 1B of the ceiling frame 1 are connected to each other.
will be installed so that they are almost on the same plane. Note that in this state, due to the lower edge 19 of the mounting bracket 13 and the bending line 20 of the base 12,
By sandwiching and engaging the surface 1A of the ceiling frame 1 from both sides, the mounting bracket 13 is prevented from moving from side to side.

Next, when it is necessary to install the louver 21 at the lower part of the open surface of the reflector 7, the support fitting 9 is attached to the mounting fitting 13.
slide upward against the In other words, in order to do so, first insert the bent portion 15 of the connecting fitting 16 into the hole 1.
8. Pull it out from the hole 11. This drawer is preferably narrowed by holding both ends 22 of the connecting fitting 16.

Once the bent portion 15 is pulled out in this manner, the connection between the supporting and mounting fittings 9 and 13 by the connecting fitting 16 is severed. In this state, the support fitting 9 is slid upward relative to the mounting fitting 13. After raising it appropriately, the bent part 15 of the connecting fitting 16 is again passed through the hole 18 to another hole 11 located below the hole 11 through which it had been inserted.
Insert into.

FIGS. 2 and 6 show the state at this time. As will be understood, the side channel 3 is now located higher relative to the ceiling frame 1 than before. If three or more holes 11 are formed as shown in the figure, the position of the side channel 3 can be adjusted in three or more stages.

(Effects of the invention) As detailed above, according to this invention, a mounting bracket that has a base that is placed on the surface of the ceiling frame is slidably attached to the support bracket that is normally used for support. , support in any sliding position,
Since the two mounting fittings can be connected freely by the connecting fitting, the lighting fixture can be set at any position along the vertical direction, which is an advantageous effect.
