Roof ridge ventilation system

A roof ridge ventilation system having a plurality of fans comprising:

• a first base member having inner and outer edges, the inner edge being adapted for pivotable interconnection along at least a portion of the length of the inner edge, said first base member having a wall for blocking wind formed therein along the length thereof adjacent the outer edge;
• a first vent member having first and second ends and inner and outer edges, the inner edge adapted for pivotable interconnection and having a pivotably connected portion along the at least a portion of the length of the inner edge of said first base member, the outer edge defining an airflow channel outer wall portion, said vent member defining a plurality of vent holes to allow for airflow through said vent member, said first vent member comprising wall means for defining a housing and a central air flow channel along the length thereof adapted for allowing airflow to pass through the vent holes;
• a second base member having inner and outer edges, the inner edge being adapted for pivotable interconnection along at least a portion of the length of the inner edge, said second base member having a wall for blocking wind formed therein along the length thereof adjacent the outer edge;
• a second vent member having first and second ends and inner and outer edges, the inner edge adapted for pivotable interconnection and comprising a pivotably connected portion along the at least a portion of the length of the inner edge of said second base member, the outer edge defining an airflow channel outer wall portion, said second vent member defining a plurality of vent holes to allow for airflow through said second vent member, said second vent member comprising wall means for defining a housing and a central air flow channel along the length thereof adapted for allowing airflow to pass through the vent holes;
• frame means retained in the central air flow channel housing and adapted for spanning the opening in the ridge portion of the roof, said frame means adapted also for retaining at least one fan member;
• a hood member having first and second ends, said hood member adapted for covering said first and second vent members and adapted for further defining an upper wall for the airflow channel which, together with said first and second vent members and their respective airflow channel outer wall portions and vent holes and the wall means for spacing said vent members from said base members together define an airflow channel adapted for the passage of air from an opening in the ridge portion of the roof through the vent holes;
• and
• first and second end members adapted for attachment to the first and second ends of said vent members respectively and the first and second ends of said hood member respectively to further define the airflow channel adapted for passage of air from the opening in the ridge portion of the roof through the vent holes.

A method of installing a roof ridge ventilation system comprising the steps of:

• attaching adjacent an elongated opening at the ridge of a roof a pair of elongated base members, each base member of the pair being installed on one side of the opening with the opening positioned along a longitudinally extending centerline between the frame means, each base member having hinged thereto an elongated vent member, the vent members being interconnected by frame means;
• placing a plurality of fan members on the frame means;
• fastening the fan members to the frame means;
• attaching a hood member over the top of the vent members and the plurality of fans contained therein with outer edges of the hood member engaging outer edges of the vent members;
• and
• attaching end members engaging end portions of each of the hood member and the vent members.

A roof ridge ventilation system housing a plurality of fans for ventilating a plurality of vent chutes comprising:

• an elongated hood member comprising first and second ends and at least one edge wall portion;
• an elongated vent member comprising first and second ends, a central air flow channel portion adapted for communicating with a plurality of vent chutes and an outer air flow channel portion adapted for engagement with the at least one edge wall portion of said hood member, said vent member having defined therein air holes adapted to allow passage of air through the air flow channels of said vent member, said vent member defining a housing portion within an air flow channel of said vent member and adapted for retaining a plurality of fans;
• first and second elongated base members, each said base member comprising first and second ends, an inner edge portion and an outer edge portion, the inner edge portion of each said base member being connected to the channel portion of said vent member, the outer edge portion of at least one said base member defining a wall adapted for blocking wind from entering the air holes of said vent member;
• first and second end members adapted for attachment to each of the first and second ends of said vent member 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 member air holes;
• and
• a plurality of fans, each fan retained within an airflow channel of the housing of said vent member.
