Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting fixture having an outer frame and an inner frame on the lower surface of the fixture body.

[Prior Art] FIGS. 9 and 10 show a conventional example, in which an outer frame 2 is formed at the outer periphery of the lower opening of an implantable device main body 1, and an end portion of this outer frame 2 is adapted to be secured to the lower surface of the ceiling material 3. An inner frame 4' is arranged inside the outer frame 2, and a panel 5 is arranged on a locking piece 4a formed on the inside opening of the inner frame 4' (see, for example, Japanese Utility Model Publication No. 1983-4962). .

[Problem to be solved by the invention]

However, in the invention of Utility Model Publication No. 62-4962,
As shown in FIG. 9 of the present application, the outer frame 2 and the inner frame 4'
Since the lower surfaces of the inner frame 4' and the like are flush with each other, there is a problem that the inner frame 4' appears to be lowered and the panel 5 etc. appear to sag, spoiling the appearance. Furthermore, although a slight gap S is formed between the outer frame 2 and the inner frame 4' as shown in FIG. When a difference in level occurs between the inner frame 2 and the inner frame 4', one of the frames becomes a gauge as shown in FIG. 11, and there is a problem in that it stands out and looks unsightly.

The present invention has been provided in view of the above-mentioned points, and it makes it less noticeable even if the outer frame and the inner frame are not parallel, and even if the inner frame hangs down, it can be kept within the outer frame. The object of the present invention is to provide a lighting fixture that does not hang down from the outer frame.

[Means for Solving the Problems] In the present invention, an inner frame 4 is disposed inside an outer frame 2 formed on the outer periphery of the lower opening of the instrument main body 1, and a panel 5 is disposed in the opening of the inner frame 4. In a lighting fixture in which a louver 17 or the like is arranged, the inner frame 4 is arranged above the outer frame 2 to create a vertical step D between the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4. It has been established.

Further, the surface treatments of the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4 are made different.

[Effect]

Therefore, the present invention arranges the inner frame 4 inside the outer frame 2 formed on the outer periphery of the lower opening of the instrument main body 1, and arranges the inner frame 4 above the outer frame 2 to form the outer frame. Since the step D in the vertical direction is provided between the lower surface 2a of 2 and the lower surface 4a of the inner frame 4, even if the panel 5 etc. is bent, the panel 5 etc.
This prevents it from sagging further downwards, and the appearance is not impaired. Moreover, by providing the step D, even if the outer frame 2 and the inner frame 4 are not parallel, it becomes less noticeable, and even if the inner frame 4 hangs down, it can be accommodated within the outer frame 2 and the outer frame 2 You can prevent it from sagging.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, an inner frame 4 is disposed inside an outer frame 2 formed at the outer periphery of the opening on the lower surface of the instrument main body 1 with a space S between the inner frame 4 and the outer frame 2. A step D in the vertical direction is provided between the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4 by disposing it above. The other configurations are the same as the conventional one, so explanations will be omitted. FIG. 2 shows the case of an embedded type, and FIG. 3 shows the case of a direct-mounted type. In both cases, as in the case of FIG. 1, the inner frame 4 is disposed above the outer frame 2, and a vertical step D is provided between the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4. FIG. 4 shows a perspective view of the entire instrument body 1.

FIG. 5 shows a cross-sectional view, in which a stabilizer 7 is arranged in a stabilizer box 6 on the upper part of the instrument main body 1.
A socket 10 for mounting a lamp 9, a reflector 11, and a U-shaped louver support frame 12 are arranged on the lower surface of the socket base 8. The inner frame 4 is detachably attached to the instrument body 1 via a mounting spring 13 and a hanging tool 14 on a support piece 15 provided on the inner surface of the louver support frame 12. A panel 5 is arranged in the inner frame 4. A vertical step D is provided between the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4, as in FIG. This appliance main body 1 is suspended by a hanging metal fitting suspended from the upper part of the ceiling, and is installed through a T-bar 18 in the system ceiling and a ventilation hole 19 of an air conditioner. The T-bar 18 and the instrument body 1 are held at a constant distance by a spacer 20. FIG. 6 shows a case where the appliance main body 1 is arranged in the shape of a rectangular frame, and the ceiling material 3 is placed on the outer frame 2 on the inside. Note that 21 is a return buffer.

In FIG. 7, louvers 17 are provided in place of the panel 5, mirrors 16 are arranged on both sides along the inner longitudinal direction of the inner frame 4, and louvers 17 are arranged at predetermined intervals in the longitudinal direction. ing. And between the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4,
Similar to FIG. 1, a step D in the vertical direction is provided. Similar to FIG. 6, FIG. 8 shows a system ceiling in which the appliance body 1 is arranged in a rectangular frame shape.

Incidentally, the appliance main body 1 itself may be formed into a rectangular frame shape, arranged as shown in FIGS. 6 and 8, and the ceiling material 3 may be disposed inside.

Further, the surface treatments of the lower surface 2a of the outer frame 2 and the lower surface 4a of the inner frame 4 may be made different. That is, by changing the color of the lower surfaces of both frames 2 and 4 or giving them different surface finishes, even if one of the frames warps or sags, it can be made less noticeable.

[Effects of the Invention] As described above, the present invention provides an arrangement in which an inner frame is arranged inside the outer frame formed on the outer periphery of the lower opening of the instrument main body, and a panel, louver, etc. is arranged in the opening of the inner frame. However, since this inner frame is arranged above the outer frame and a vertical step is provided between the lower surface of the outer frame and the lower surface of the inner frame, even if the above-mentioned panels are bent, the It is possible to prevent the panel etc. from hanging down below the outer frame, and there is an effect that the appearance is not impaired. Moreover, by providing the above-mentioned step, it becomes less noticeable even if the outer frame and inner frame are not parallel, and even if the inner frame does sag, it is kept within the outer frame so that it does not sag below the outer frame. It also has the effect of being able to do it.

Furthermore, by using different surface treatments on the lower surface of the outer frame and the lower surface of the inner frame, it is less noticeable even if one of the frames warps.
