見地からは採用しずらいものである。As described above, in the method of manufacturing the lighting fixture mounting bracket , the stepped portion is formed in the upper surface direction by the thickness of the sheet metal before cutting and separating the outer frame and the intermediate plate . Therefore, after cutting and separating the outer frame and the middle plate, the middle plate needs to be turned over with respect to the outer frame and then shipped in combination. The reason for this is that when the metal fitting is mounted on the ceiling, the surface of the middle plate on the ceiling side and the surface of the outer frame on the ceiling side are flush with each other. However, from the viewpoint of the manufacturing process, reversing the middle plate increases the number of steps, which is difficult to employ, especially from the viewpoint of automation.
【０００４】本発明はこうした実情を鑑み、製造工程の
簡素化を図った照明器具取付金具の製造方法を提供しよ
うとするものである。The present invention has been made in view of the above circumstances, and has as its object to provide a method of manufacturing a lighting fixture mounting bracket with a simplified manufacturing process.

付金具の製造方法を構成する。SUMMARY OF THE INVENTION The present invention is directed to a lighting fixture mounting bracket having an outer frame and a middle plate cut and separated from a sheet metal, and combining a step formed on the outer periphery of the middle plate on the inner bottom surface of the outer frame. In the manufacturing method of (1), before cutting and separating the outer frame and the middle plate, the step portion is formed into a stepped shape in the bottom direction by the thickness of the sheet metal to constitute a manufacturing method of the lighting fixture.

せずに両者を組み合わせて出荷するだけでよい。According to the present invention, the step portion is formed in a stepped shape in the bottom direction by the thickness of the sheet metal before the outer frame and the middle plate are cut and separated , so that the outer frame is cut after the outer frame and the middle plate are cut and separated. However, it is only necessary to ship the combination of the two without turning over the middle plate.

出荷される。That is, in the manufacturing process shown in FIG. 3, the step portion 10 is already formed into a stepped shape in the bottom direction by the thickness of the sheet metal, and the outer frame A and the intermediate plate B finally left in the process are joined together. The parts A, B, C, and D are cut and separated to form two pieces into an outer frame A and a middle plate B. Then, the middle plate B is slightly rotated in the direction of the arrow without being inverted, and then The cut-and-raised pieces 5 and 5 of the outer frame A are inserted and locked into the holes 4 and 4, respectively.
