Solar house with roof board of adjustable inclination

摘要

A roof structure of a building having two roof surfaces, one being downwardly inclined from a top ridge in a southernly direction, and the other being downwardly inclined from the ridge in a northernly direction. South and north side openings extend upwardly through the roof surfaces on opposite sides of the ridge. A shaft is rotatably along the top ridge. A roof board selectively closes off one of the south and north side openings. The roof board has a central part supported by the shaft as a fulcrum for swinging movement between a first position wherein a southern portion of the roof board closes the south side opening and a second position wherein a northern portion of the roof board closes the north side opening. A skylight is supported on the roof board adjacent one end edge thereof.
