A roof apparatus includes a plurality of light collecting members, each having a pair of left and right vertical members, an upper horizontal member, a lower horizontal member, and a transparent plate. The upper horizontal members are disposed at a ridge side end of the vertical members, the lower horizontal members are disposed at an eaves side end of the vertical members, and the transparent plate is disposed on the inner periphery of the vertical members, the upper horizontal member, and the lower horizontal member. The light collecting members are connected in a slope direction of the roof, and the lower horizontal member has a transparent plate holding piece, a transparent plate contact wall, and a cover piece. The transparent plate holding piece is adapted to hold an eaves side end of the transparent plate. The transparent plate contact wall has a thickness which is smaller than the thickness of the transparent plate. The cover piece is adapted to cover an upper portion of the upper horizontal member of an adjacent eaves side light collecting member and extends from the upper end of the transparent plate contact wall. |

DETAILED DESCRIPTION An object of the present invention is to provide a roof apparatus for having a well drainage in the eaves direction of the roof, effectively flashing a connecting portion between a lower horizontal member and an upper horizontal member, preventing dust, rubbish, and the like from staying on the upper surface of a transparent plate, and suppressing a decrease of light collecting efficiency.
The present invention is a roof apparatus, comprising a plurality of light collecting members, each of the light collecting member having a pair of (left and right) vertical members, an upper horizontal member, a lower horizontal member, and a transparent plate, the upper horizontal member being disposed at a ridge side end of the vertical members, the lower horizontal member being disposed at an eaves side end of the vertical members, the transparent plate being disposed on the inner periphery of the vertical members, the upper horizontal member, and the lower horizontal member, the light collecting members being connected in a slope direction of a roof, wherein the lower horizontal member has a transparent plate holding piece, a transparent plate contact wall, and a cover piece, the transparent plate holding piece being adapted to hold an eaves side end of the transparent plate, the transparent plate contact wall having the thickness which is smaller than the thickness of the transparent plate, the cover piece being adapted to cover an upper portion of the upper horizontal member of an adjacent eaves side light collecting member and extending from the upper end of the transparent plate contact wall.
The vertical members each comprises a plurality of water proof protrusions longitudinally formed at an upper end of the inner surface of the vertical wall, a horizontal protrusion piece disposed on the inner surface at the lower end of the vertical wall, and a vertical support leg being disposed at the inner end of the horizontal extrusion piece and vertically extending.
The vertical wall and the vertical support leg each define a ventilation notch at the lower end on an eaves side end and a ridge side end thereof
