Snap door vent

A vent assembly for a vehicle having a ventilation opening formed in a wall thereof, said assembly comprising

• a vent cover adapted to be fixed to a vehicle wall to cover a ventilation opening therein, said vent cover comprising a front wall portion sloping rearwardly and outwardly to an outer vent region, whereby air flowing over said vent assembly is deflected by said front wall portion to flow with decreased pressure at said outer vent region,
• said vent cover having a pair of opposed cover openings extending laterally in opposite directions across at least part of said outer vent region,
• first and second doors,
• means for mounting said doors at respective ones of said cover openings for movement from a first position wherein said cover openings are closed and sealed by said doors and a second position wherein said doors are displaced inwardly of said cover openings at said outer vent region, and
• means for holding said doors in said first position.

A vehicle vent assembly for a vehicle ventilation opening, said assembly comprising

• a vent cover adapted to be secured to a vehicle in position to cover a ventilation opening thereof, said cover comprising
• a front wall sloping rearwardly and
• outwardly of said cover to an outer cover region displaced outwardly of said ventilation opening,
• said cover having an opening positioned at least in part at said outer cover region,
• closure means having a pivotal connection to said cover and adapted to move between a closed position in which said cover opening is closed by said closure means and a second position inwardly displaced from said outer cover region, and
• latch means for exerting upon said closure means a force directed toward said pivtal connection.

A vehicle vent assembly comprising

• a vent frame adapted to be mounted in an opening of a vehicle, said vent frame having front, back and side members,
• a vent cover fixed to said frame and having a generally dome-like configuration sloping rearwardly and outwardly to an outer dome region and sloping forwardly and outwardly to said outer dome region, said vent cover having a pair of mutually opposed cover openings therein each sloping outwardly from a respective one of said side members toward said outer dome region, each said opening having a relatively small extent adjacent said outer dome region and having a relatively great extent on the side thereof remote from said outer dome region,
• first and second doors pivoted to said cover and side members adjacent said side members and each having a free end, each said door having a shape substantially conforming to the shape of a respective one of said openings and being slightly larger than the associated opening to overlap opening perimeters, said doors being pivotally movable to a closed position in overlapping engagement with the perimeters of said openings and to an open position in which said free ends are displaced inwardly of said cover, and
• means for holding said doors in said closed position.

A vent assembly for a vehicle having a ventilation opening formed therein, said assembly comprising

• a generally dome shaped vent cover having a front face sloping outwardly and rearwardly to an outer vent region,
• said vent cover having a plurality of cover openings extending across at least part of said outer vent region,
• a plurality of resilient, outwardly bowed doors pivotally connected to said cover at mutually remote sides of said cover openings and having mutually spaced and adjacent free end portions,
• said doors being movable to a first position wherein said cover openings are closed and sealed by said doors and to a second position wherein said doors are displaced inwardly of said cover openings, and
• latch means interposed between said doors for exerting compressive forces on said free end portions, said forces being exerted along lines extending at a small angle to the planes of said doors, respectively, whereby said latch means tends to increase the outward bowing of said doors and to force said doors to said first position.
