Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a lighting device using 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. It is configured to be attached to a ceiling frame using metal fittings, and to support sockets, reflectors, etc. on this side channel.

However, in the past, the end of the above-mentioned mounting bracket was simply placed over the head of the ceiling frame, so if for some reason there was vibration in the vertical direction, the mounting bracket could come off the ceiling frame. It may get stuck and fall downward.

(Problem that the invention aims to solve) This invention uses mounting brackets attached to the side channels to support lighting equipment on the ceiling frame, and the mounting brackets may fall off from the ceiling frame due to vertical vibration. The purpose is to prevent this from happening.

(Means for Solving the Problems) In this invention, a mounting bracket is attached to the side channel that supports the lighting equipment, a support piece in which a long hole is formed in the horizontal direction is provided on the mounting bracket, and a handle is attached to the mounting bracket. A hook portion having a shape that can pass through the long hole is provided at the tip of the provided shaft, and by inserting the hook portion into the long hole and rotating the shaft, the hook portion is attached to the ceiling frame. It is characterized by being engaged with a key groove in the side wall of.

(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 device, which includes a pair of side channels (only one is shown in the figure) 3;
This supports a socket 4, a reflector plate 5, and other fixtures necessary for the lighting equipment. 6 is a cushion material, 7 is a lead wire, and 8 is a ceiling board.

Reference numeral 9 denotes a mounting bracket, which is attached to the side channel 3. In the illustrated example, a linear spring 11 whose upper end elastically engages with the side channel 3 is used for this attachment. The tip of the spring 11 is inserted through and engaged with the mounting bracket 9 from the back side toward the front side, and the spring 11 is rotated by its elasticity. This rotation fixes the mounting bracket 9 to the side channel 3.

The mounting bracket 9 is placed on the head 12 of the ceiling frame 1. Specifically, the flat lower part 13 of the mounting bracket 9 rests on the head 12, and the tip of the lower part 13 is a vertical part 14, which is attached to the head 12.
It is arranged so that it faces the outside surface of the

Further, the mounting bracket 9 is provided with a support piece 15 integrated by welding or the like, and this support piece 15 faces the inner surface of the head 12. The support piece 15 and the vertical portion 14 prevent the mounting bracket 9 from shifting in the lateral direction with respect to the ceiling frame 1.

A long hole 16 that is long in the horizontal direction is formed in the support piece 15 . A shaft 18 also provided with a handle 17
Then, a hook 20 having a hook portion 19 at the tip of the shaft 18 is prepared. The hook part 19 is a long hole 16
Similarly, it has a horizontally elongated shape and can freely pass through the elongated hole 16. Diameter of shaft 18 and elongated hole 16
It is best to make the short axis approximately equal. 21 is a keyway formed in the wall surface of the ceiling frame 1.

To fix the mounting bracket 9 placed on the head 12 to the ceiling frame 1, insert the hook 19 into the elongated hole 16, and then use the handle 17 to tighten the shaft 18 by approximately 90°.
Rotate degrees. This rotation causes the hook 19 to stand upright, and at this time, one end of the hook 19 engages with the keyway 21 of the ceiling frame 1 from below. At this time, the hook part 19 is connected to the keyway 21 and the ceiling frame 1.
It comes to be engaged by fitting between it and the wall surface of.

If the mounting bracket 9 and the ceiling frame 1 are connected through this engagement, even if the ceiling frame 1 or the lighting fixture 2 vibrates in the vertical direction, they will vibrate as one, and the mounting bracket 9 Therefore, lighting equipment 2
This will surely prevent the ceiling frame 1 from rising above the ceiling frame 1.

In order to remove the hook 19 once engaged, it is sufficient to rotate the shaft 18 by approximately 90 degrees, thereby releasing the engagement between the hook 19 and the keyway 21.

(Effects of the invention) As detailed above, according to this invention, it is possible to prevent the lighting fixture from shifting in the lateral direction, and to simply insert the hook provided at the tip of the shaft into the ceiling frame by passing the hook provided at the tip of the shaft through the support piece provided on the mounting bracket. With a simple structure that requires only engagement with the keyway of the lamp, lifting of the lighting equipment can be reliably avoided.
