NATURAL LIGHTING COVER MATERIAL CAPABLE OF BEING VENTILATED

摘要

PROBLEM TO BE SOLVED: To simultaneously perform natural lighting and ventilation on the same place and simply fit the members to the place by alternately turning over transparent or translucent gutter-like natural lighting members so as to pile up the ribs of the natural lighting members, and forming gaps between the piled up ribs so as to form opening parts. ;SOLUTION: Ribs are formed on both edges in the lengthwise direction of an upper side gutter-like natural lighting member 8 and a lower side gutter-like natural lighting member 9. Next these gutter-like natural lighting members 8, 9 are alternately arranged so as to form a natural lighting plate 7. Next the natural lighting plate 7 is sandwiched between an upper frame 5 and a lower frame 6, and fixed by means of screws 10. When the ribs of the gutter-like natural lighting members 8 and the ribs of the gutter-like natural lighting members 9 are piled, gaps for ventilation are formed between both ribs. Further, for surely preventing invasion of rain water, it is inclined inside. Hereby, natural lighting and ventilation can be simultaneously performed on the same place.;COPYRIGHT: (C)1998,JPO
