Description

[Detailed explanation of the idea] This invention relates to a lighting fixture mounting device.

BACKGROUND OF THE INVENTION The main body of a lighting fixture is fitted into a rectangular structure that is hung from above on a ceiling or the like. Typically, such a configuration is widely used in air conditioning lighting equipment. Figure 1 shows the conventional configuration, 1
is a rectangular structure, and is usually constructed by assembling T-bars 2 into a rectangular shape. As shown in FIG. 2, the structure 1 is installed so that its horizontal walls 2A are lined up along the ceiling surface 3, and is suspended from the top by bolts or the like. 4 is the main body of the lighting equipment, 4A is its side wall, 5 is a translucent panel, and 6 is a frame for holding the panel, which is movable up and down along the side wall 4A with a spring or the like, and the main body 4 of the lighting equipment is in the raised position. will be integrated into. The instrument body 4 is supported on the construction 1 by a suitable mount, such as by using the upper end of the T-bar 2.

Incidentally, in this type of lighting equipment, the main body 4 of the lighting equipment is housed in a frame by being pushed up from below the structure 1 assembled into a rectangular shape. Therefore, unless the instrument main body 4, or more precisely the frame 6, is a little smaller than the frame of the construction 1, the instrument main body 4 cannot be accommodated within the frame of the construction 1.
However, if it is slightly smaller like this, the edge of the horizontal wall 2A of the T-bar 2 and the frame 6 are
It is unavoidable that a gap 7 is generated between the outer peripheral edge 6A and the outer peripheral edge 6A. And such a gap 7 is not constant.
Therefore, the presence of such an indefinite gap impairs the appearance of the lighting fixture.

The purpose of this invention is to install a lighting fixture so that there is no indefinite gap between the inner surface of the structure and the outer periphery of the frame.

An embodiment of this invention will be explained with reference to FIG. 3 and subsequent figures. Note that parts given the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts. In this invention, the horizontal wall 2A of the T-bar 2 is bent upward into a key shape to form a bent portion 2B. and bent part 2
A raised edge 6B formed by raising the outer periphery of the frame 6 from below is engaged with B. To explain this installation order in detail, first, the instrument main body 4 is supported by the T-bar 2. At this time, it is preferable to lower the frame 6 with respect to the instrument body 4. The instrument body 4, T
After being supported by the bar 2, the frame 6 is raised to a predetermined position relative to the instrument body 4. When this raised position is reached, the tip of the upright wall 6B engages with the inner surface of the bent portion 2B as shown in FIG. 4.

When the lighting fixture is installed as described above, the upright wall 6B of the frame 6 does not need to pass through the frame of the T-bar 2, and moreover, it engages with the bent part 2B, so 6B, there is hardly any gap, and even if it does, it is very small and is almost constant. Therefore, with this mounting state, it is possible to avoid spoiling the appearance due to gaps.

In the configurations shown in FIGS. 1 and 2, the horizontal wall 2A of the T-bar 2 and the frame 6 are present between the edge of the ceiling surface 3 and the periphery of the panel 5. Since this part is not a part through which light passes, the periphery of the panel 5 has a dark part with a certain width. However, in this invention, as shown in FIGS. 3 and 4, the inclined inner wall 6C of the frame 6 is extended upward so that the panel 5 is located above the horizontal wall 2A. In this way, the width of the horizontal wall 2A is reduced to about half due to the presence of the bent portion 2B, and the inner wall 6C
is illuminated by the light coming out through the panel 5. As a result, the width of the dark portion at the periphery of the panel 5 appears to be narrower, which is convenient.

As detailed above, according to this invention, a lighting fixture can be installed in a rectangular structure without any gap or with a slight fixed gap, and the appearance of the fixture in the installed state is not impaired. Moreover, the width of the dark area around the panel appears narrower, which has the effect of making it appear narrower.
