Roof ridge ventilation system

摘要

Roof ridge vent system adapted for housing a plurality of fans in a central airflow channel positioned directly over the opening in a ridge portion of a roof for ventilating a plurality of vent chutes or attic space comprising: a hood member engaged with outer edge portions of vent members having air-passageway holes defined therein and inner edge portions preferably being hinged respectively to inner edge portions of base members so as to be adapted for installation on variously-pitched roofs, each base member also having outer edge portions defining a wall adapted for blocking wind from being blown into the vent and for causing airflow over the top of the vent to encourage airflow through the vent system. Vent member sections may be installed end-to-end to define an elongated airflow channel adapted for ventilating with or without assistance from the fans.

1. A roof ridge ventilation system comprising:
a hood member comprising first and second ends and first and second outer wall portions; first and second vent members comprising first and second ends and inner edge portions and outer edge wall portions, the outer edge wall portions of said vent members adapted for engagement with the outer wall portions of said hood member for defining outer vent walls, said vent members comprising central wall means defining a central air flow channel, the vent members also comprising ledges along the inner edge portions of the vent members, and said vent members having defined therein air holes adapted to allow passage of air through said vent members; first and second base members corresponding to said first and second vent members and comprising inner and outer edge portions, the inner edge portion of each said base member being hinged respectively to the corresponding inner edge portion of each said vent member so as make each hinged first base member and corresponding first vent member adapted for installation on the ridge area of differently-pitched roofs without requiring bending of the base member or corresponding vent member, each of the outer edge portions defining a wall adapted for blocking wind from entering the air holes of said vent members; a plurality of spanning frame members supported by the ledges of the vent members, said spanning frame members adapted for spanning an opening in the ridge portion of the roof, and for interconnecting said first vent member and said first base member with said second vent member and said second base member, said vent and base members being adapted for being installed one of each on each side of the opening in the ridge portion of the roof, said spanning frame members and said ledges being adapted for retaining a plurality of fan members directly above the opening in the ridge portion of the roof between said first and second vent members; and first and second end members adapted for attachment to each of the first and second ends of said vent members and the first and second ends of said hood member to further define the airflow channel adapted for passage of air from the opening in the ridge portion of the roof through the vent air holes.
