Thus, by lowering and fixing the lighting box 6, the canopy of the elevator can be thinned, and the transportability can be improved. Further, by packing in this flat state, the packing space can be reduced as compared with the conventional elevator ceiling structure in which the lighting box 6 protrudes and is fixed, and space can be saved also in the packing form. it can.
[0031]
When normal elevator operation is performed after the elevator is installed, the fixing screw 16 is screwed and fixed in a state where the lighting box 6 is lifted as shown in FIGS. At this time, the lighting box 6 protrudes from the flat surface 12c of the canopy reinforcement 12, but since the operator does not get on the canopy surface of the car 2 during normal operation, it can be operated without any inconvenience. . In this way, by projecting and fixing the illumination box 6 from the canopy reinforcement 12, a sufficient interval between the circular fluorescent lamp 9 attached to the illumination box 6 and the illumination plate 7 can be secured, and there is no light unevenness. The illumination plate 7 can be illuminated.
[0032]
Further, at the time of elevator installation work or maintenance, the fixing screw 16 is screwed and fixed at the position where the illumination box 6 is lowered as shown in FIGS. 3 and 6A. When the lighting box 6 is fixed at the lowered position, the flat surface 12c of the canopy reinforcement 12 and the upper surface of the lighting box 6 can be arranged in the same plane. Thus, since the entire canopy surface of the car ceiling can be flattened without unevenness, it is possible to prevent the operator from whispering during the work, and to further improve safety.
