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 is usually installed as shown in Figs. 6 and 7. A lighting fixture 2 is installed across a pair of parallel ceiling frames 1. Specifically, the ceiling frame 1 is fixed so as to hang from the ceiling, and the end portion 4 of the lighting fixture 1 is placed on the lower wall 3 of the ceiling frame 1. 5 is a fluorescent light.

By the way, in such an installation state, as conditions required for the installation, it is necessary to prevent the lighting fixture 1 from floating upward and to prevent the end portion 4 from sliding along the lower wall 3. can give.

Therefore, conventionally, configurations as shown in FIGS. 8 and 9 have been used. That is, a plate-shaped spring 6 is attached to the end 4, and its tip is attached to the vertical wall 7 of the ceiling frame 1.
The end portion 4 was inserted into a hole 8 provided in the ceiling frame 1, thereby engaging the end portion 4 with the ceiling frame 1.

However, with such a configuration, the lighting fixture 1 can only be installed at a location corresponding to the hole 8 previously formed in the vertical wall 7, and the lighting fixture 1 cannot be installed at other locations, which is inconvenient. be.

(Problems to be Solved by the Invention) The object of this invention is to make it possible to install a lighting fixture at any position relative to the ceiling frame in a state in which it is engaged with the ceiling frame.

(Means for Solving the Problems) This invention includes an upper wall portion, a hanging wall portion extending downward from the upper wall portion, and having a bent portion at the lower end that engages with the neck of the head of the ceiling frame. It consists of a mounting bracket whose end part is fixed to a lighting fixture placed on the lower wall of the ceiling frame, and a mounting screw screwed into the upper wall part, and the hanging wall With the bent part of the upper wall part engaged with the neck of the head of the ceiling frame, and the tip of the screw in contact with the surface of the head, the upper wall part is connected to the neck of the head of the ceiling frame. The screw is screwed into the upper wall portion so as to move in a direction away from the upper wall portion.

(Example) An example of this invention will be explained with reference to FIGS. 1 to 5. Note that parts given the same reference numerals as in each figure after FIG. 6 indicate the same or corresponding parts. According to this idea, a mounting bracket 11 is prepared.
The mounting bracket 11 includes an upper wall portion 12 and a hanging wall portion 16 that extends downward from the middle of the upper wall portion and has a bent portion 15 at the lower end that engages with the neck portion 14 of the head portion 13 of the ceiling frame 1. It is equipped with This mounting bracket 11 is fixed to the end 4 of the lighting fixture 2.

A mounting screw 17 is screwed into the upper wall portion 12 of the mounting fitting 11. The upper wall portion 12 of the mounting bracket 11 shown in the figure is constructed by folding a metal plate in half. A hole 18 is formed in the upper plate 12A, and a screw hole 19 into which a screw 17 is screwed is formed in the lower plate 12B, for example, by a countersink. Note that the hanging wall portion 16 is formed continuously at the tip of the lower plate 12B.

In the above configuration, first, the end portion 4 of the lighting fixture 1 is placed on the lower wall 3, and the bent portion 15 of the hanging wall portion 16 is brought into contact with the neck portion 14. Then, the tip of the screw 17 is faced to the surface of the head 13 of the ceiling frame 1, and the screw 17 is screwed into the upper wall portion 12.

As a result of this screwing, as shown in FIG. 4, when the tip of the screw 17 comes into contact with the surface of the head 13,
A space S is still left between the head of the screw 17 and the upper wall portion 12. When the screw 17 is further screwed in from this state, the upper wall portion 12 moves in a direction away from the head 13, as shown in FIG. In other words, the upper wall portion 12 rotates clockwise using the abutment point between the bent portion 15 and the neck portion 14 as a fulcrum.

As a reaction force of this movement of the upper wall portion 12, the end portion of the lighting fixture 2 is pressed against the surface of the lower wall 3 of the ceiling frame 1 via the mounting bracket 11, and comes to be in close contact with the surface of the lower wall 3 of the ceiling frame 1. Due to this close contact, the lighting fixture 2 can be reliably attached to the ceiling frame 1 while being prevented from lifting or sliding.

Since the mounting fitting 11 is formed by the upper wall part 12 and the hanging wall part 16, it has the advantage of using fewer parts and having a simple structure.

(Effects of the invention) As detailed above, according to this invention, lighting equipment can be installed at any position relative to the ceiling frame simply by screwing in the screws, thus making it possible to install the lighting equipment in any position relative to the ceiling frame. The inconvenience caused by restrictions on the installation position is eliminated, and the operation is extremely simple, as all you have to do is screw in the screws.Furthermore, even when installed, the appliance body can be firmly attached to the ceiling frame. Moreover, the structure of the mounting bracket for this purpose is also simple.
