Baffle vent structure

A baffle vent for positioning against the underside of a roof and defining a duct between the vent and the interior surface of the roof for directing air from the soffit area of the roof upwardly over the interior surface of the roof, the duct having a first end with an opening below the roof for admitting air into the duct and a second end with an opening longitudinally spaced from said first end, the baffle vent comprising:

• an elongated self-supporting structure of sheet-like material having a generally channel-shaped cross section including a flat generally planar bottom wall, and a plurality of longitudinal reinforcing ribs of substantially equal length in the bottom wall in an in-line orientation and with spaced adjacent ends whereby the structure can be cut to length between the spaced adjacent ends of a pair of said longitudinal reinforcing ribs, said spaced adjacent ends tapering lengthwise of said structure into said bottom wall,
• each of said plurality of longitudinal reinforcing ribs having first and second sides tapering crosswise of said structure from an apex of each rib into said bottom wall to define a generally triangular cross-sectional configuration for each of said ribs, and
• each rib having first and second triangularly shaped ramped ends tapering lengthwise of said structure into said bottom wall.

• an elongated self-supporting structure of sheet-like material having a generally channel-shaped cross section defining longitudinal side walls joined by a flat generally planar bottom wall, attachment means on the sidewalls for attaching the baffle vent to the underside of the roof, and a plurality of discrete longitudinal reinforcing ribs of substantially equal length and all aligned in a single line and extending lengthwise of the bottom wall to resist collapsing of the baffle vent if subjected to external forces such as from roof insulation, handling, shipping and the like, said longitudinal ribs having first and second ramped ends tapering lengthwise of said structure into said bottom wall.

• an elongated self-supporting structure of sheet-like material having a generally channel-shaped cross section defining longitudinal side walls joined by a flat generally planar bottom wall, attachment means on the sidewalls for attaching the baffle vent to the underside of the roof, and a plurality of integral reinforcing ribs of generally triangular cross-sectional configurations and spaced in an in-line orientation longitudinally of the bottom wall and with spaced adjacent ends of a pair of said longitudinal in-line reinforcing ribs, said longitudinal ribs having first and second generally triangularly shaped ramped ends tapering lengthwise of said structure into said bottom wall.

• an integral transverse reinforcing rib extending across the bottom wall between adjacent ends of a pair of said longitudinal in-line reinforcing ribs.
