Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a reflective shade for a lighting fixture that is attached to, for example, a ceiling.

[Technical background of the invention and its problems]

Conventionally, a reflector shade including a reflector plate and an end plate made of sheet metal is generally assembled using electric welding such as spot welding. Therefore, it is not possible to use a steel plate that has been surface-treated in advance, such as a colored steel plate, and is instead painted after assembly. This complicates the process and is disadvantageous in terms of cost.

There are also some that use colored steel plates instead of welding, but in this case, it is necessary to use connectors such as screws and rivets to fix each member, so these connectors are attached to the bottom of the reflective shade. The drawback was that it was exposed and the appearance deteriorated.

[Purpose of invention]

The present invention was developed based on the above circumstances, and its purpose is to make it possible to use plates that do not require painting after assembly, such as colored steel plates, which are highly rigid, strong, and have a good appearance. An object of the present invention is to provide a reflective shade for lighting equipment.

[Summary of the idea]

The gist of the present invention is an open-bottom sheet metal lighting device that is constructed of a reflector, side plates located on the left and right sides of the reflector, and end plates located before and behind the reflector and the side plates. In the reflective shade for appliances, a folded part bent in a substantially U-shape is provided at the lower edge of the side plate and the lower edge of the end plate, respectively, and each folded part has an engagement groove that fits into each other from above and below. By forming and fitting these together, the lower part of the side plate and the lower part of the end plate are connected to each other, and the upper part of the side plate and end plate and the reflector plate are connected to each other by connecting tools such as screws or rivets. This is due to the fact that they are connected.

According to the above configuration, since the folded part bent into a substantially U-shape is provided in the shape of the lower opening of the reflective shade, when it is installed on a ceiling etc. is not exposed, and a desirable design can be obtained. Further, due to the presence of the folded portion having a substantially U-shaped cross section, even a thin sheet metal can be provided with sufficient rigidity, and the engagement of these engaging grooves allows for a strong connection. and,
Because it can be assembled without welding or bending, it is possible to use metal plates that have been surface-treated in advance, such as colored steel plates, which simplifies the process and reduces costs. This is effective in reducing

On the other hand, the side plates 4, 4 are provided with a substantially U-shaped folded portion 30 at their lower edges, and are provided with a substantially L-shaped bent portion 31 at their upper edges. Then, screws 3 are attached to both ends of the bent portion 31 in the front and back direction.
Holes 34, 34 are formed through which the screws 2, 32 are inserted. Furthermore, engagement grooves 36, 36 are formed in the folded portion 30 along the vertical direction.

Further, each end plate 6, 6 is configured as follows. That is, the lower edges of the end plates 6, 6 are provided with folded portions 40 that are bent inward in a substantially U-shape, and the folded portions 3 are provided at both left and right ends of the folded portions 40.
An engagement groove 42 is formed into which the end portion of 0 fits. The above-mentioned engagement groove 36 is adapted to fit into the upper part 44 of this engagement groove 42 .

In addition, both sides of the end plates 6, 6 are bent into a substantially L shape,
Bent portions 46, 46 are formed. A horizontal portion 46 located at the upper end of the bent portions 46, 46
Screw holes 50, 50 are formed in a, 46a. Further, the upper ends of the end plates 6, 6 are provided with bent portions 52, 52 bent into a substantially L shape. The bent portions 52, 52 are provided with screw holes 54, 54.

To assemble the above-mentioned members, the ends of the side plates 4 are overlapped from the outside of the bent portions 46 so that the engagement grooves 42 of the end plates 6 mesh with the engagement grooves 36 of the side plates 4. Then, by means of screws 32, the horizontal part 4
6a is fixed to the end of the bent portion 31. Further, the ends of the bent portions 21 of the reflector are stacked on the outside of the bent portions 52 and fixed to each other from the outside with screws 23. In addition, a slit 9 provided on the convex portion 8 of the reflector
