PROBLEM TO BE SOLVED: To provide a luminaire which is neat like craftsmanship without attaching a wood screw nor attaching decoration to the undersurface of a lower frame by industrial production without using craftsmanship. SOLUTION: This luminaire includes: an upper frame having a through-hole at each corner part, and having panel grooves on the undersurface; the lower frame having panel grooves on the upper surface, and having a recessed part on the upper surface of each corner part; mounting members each mounted in the recessed part by screws, and having a mounting hole at the center; columns interposed between the upper frame and the lower frame on the mounting members, and each having a vertically-penetrating through-hole, and panel grooves on side surfaces; panels interposed between the respective panel grooves by being caught by the upper frame, the lower frame and the columns; and headed threaded rods each screwed into a threaded hole of the mounting member by vertically passing through the through-holes of the upper frame and the column, and having a head at the upper end. Instead of a headed threaded rod, a threaded rod having a screw at the upper end, and a nut member screwed to the screw at the upper end of the threaded rod are used. COPYRIGHT: (C)2009,JPO&INPIT |
