| 454260000 | Through roof eaves or rafters | 7 |
| 20080280554 | Adjustable Width Vent Baffle - An adaptable vent baffle mountable to an underside of a roof deck and to a wall plate of a building structure between a pair of roof rafters having a rafter spacing for permitting ventilation between a soffit and an attic space of the building structure. A main body portion has a longitudinal axis and is positioned generally on a main body place. A spacer extends from the main body portion and a tail portion is hingedly mounted to the main body portion. The main body portion and tail portion include first and second side edges and a baffle width is defined between the first and second side edges. At least one line of weakness extends generally parallel to the longitudinal axis for modifying the baffle width to adapt to the rafter spacing. | 11-13-2008 |
| 20090130969 | OFF-PEAK AIR INTAKE VENT - An off-peak intake vent includes spaced top and bottom walls defining a cavity therebetween and a pair of lateral side walls. The bottom wall has a generally planar bottom surface having at least one vent opening formed therethrough for communicating with an opening in a roof deck. The top wall has a curved portion that converges with the bottom wall at an uphill edge of the intake vent. The intake vent also includes air intake louvers defined between the top and bottom walls. | 05-21-2009 |
| 20120178356 | Attic inlet - An attic inlet has a square tube to communicate between an attic and a room through a substrate, and a lid to permit airflow through the inlet when open, and prevent it when closed. The lid is moved by an upper pull bar and lower connecting bars attached to the lid. Upper pull bar and lower connecting bars are attached by clevis pins to yoke arms pivoting about parallel axles. Movement of the upper pull bar rotates the yoke arms, and so lowers the connecting bars and the attached lid. Springs urge pull bar and lid into closed default position, while a cord is used to displace pull bar and lid into open position. The lid is attached by tabs on the connecting bars passing through the lid, and lid locking bars engaging apertures in the tabs. | 07-12-2012 |
| 20130023197 | OFF-PEAK AIR INTAKE VENT - An off-peak intake vent includes spaced top and bottom walls defining a cavity therebetween and a pair of lateral side walls. The bottom wall has a generally planar bottom surface having at least one vent opening formed therethrough for communicating with an opening in a roof deck. The top wall has a curved portion that converges with the bottom wall at an uphill edge of the intake vent. The intake vent also includes air intake louvers defined between the top and bottom walls. | 01-24-2013 |
| 20130210337 | System and Method for Protecting Interior Spaces - Disclosed herein is a new and improved system and method for protecting interior vented spaces of structures from damage due to moisture entering through vents. The system may include a brace configured for mounting to the roof sheeting around the vent opening. The system may include a tray configured to catch moisture entering the interior vented spaces through the vent opening. The system may also include a vertical support extending from the brace to the tray. | 08-15-2013 |
| 20130273827 | Attic inlet - An attic inlet has a square tube to communicate between an attic and a room through a substrate, with a lid permitting airflow when open, and not when closed. The lid is moved by upper pull bars and lower connecting bars attached to the lid. Upper pull bars and lower connecting bars are attached by clevis pins to yoke arms pivoting about parallel axles. Springs may urge the lid into closed default position. An axle with an associated stub arm may be rotated by cord to open the lid. Alternatively a counterweighted arm may urge the lid into closed default position, where negative pressure can open the lid. The lid is attached by tabs on the connecting bars passing through the lid, and lid locking bars engaging apertures in the tabs. | 10-17-2013 |
| 20130273828 | VENTILATION ARRANGEMENTS - A ventilation arrangement housing which has an upper curved guide member and a cruciform arrangement of divider plates to define the housing into quadrants. Air may enter and exit the housing via a louvre arrangement. | 10-17-2013 |
