Patent ID: 7984592

Claim:
A grain bin configured to store grain therein, comprising: a grain bin side wall structure comprising corrugated metal creating a substantially circular-shaped container; a grain bin roof comprising: a plurality of linked-together sheets which, when combined and coupled together, cover an interior of the grain bin side wall structure from exposure to weather; a first sheet of said plurality of sheets configured with a first inner rib end and an opposing first outer rib end with a first flat rib separating segment disposed therebetween; said first inner rib end further comprising: a first inner partially exposed sloped side coupled to said first flat rib separating segment and further coupled to said first inner top side which is coupled to a first inner covered sloped side; disposed in at least one of said first inner partially exposed sloped side and said first inner top side is a plurality of first inner covered orifices for facilitating ventilation; said first outer rib end further comprising: a first outer full sloped side which is coupled between said first flat rib separating segment and a first outer top full side which is coupled with a first outer partial sloped side; a second sheet of said plurality of sheets configured with a second inner rib end and an opposing second outer rib end with a second flat rib separating segment disposed therebetween; said second inner rib end further comprising: a second inner partially exposed sloped side coupled to said second flat rib separating segment and further coupled to said second inner top side which is coupled to a second inner covered sloped side; disposed in at least one of said second inner partially exposed sloped side and said second inner top side is a plurality of second inner covered orifices for facilitating ventilation; said second outer rib end further comprising: a second outer full sloped side which is coupled between said second flat rib separating segment and a second outer top full side which is coupled with a second outer partial sloped side; said second outer rib end of said second sheet is configured to nest over top of said first inner rib end of said first sheet so that said second outer partial sloped side and said first inner partially exposed sloped side form an airflow gap therebetween and in combination inhibit precipitation from entering an interior of said grain bin side wall structure through said first inner covered orifices while still permitting a substantial air flow to occur through said airflow gap between said second outer rib end and said first inner rib end and through said first inner covered orifices.
