Abstract

A passive venting device for venting enclosures comprising a base member, an intermediate splash member including a diverter, and a top, dome-shaped member. In a preferred embodiment, the diverter may be molded as a single unit of manufacture with the base member. The venting device allows air and other gases to escape from within an enclosure to be vented while preventing the incursion of moisture in the form or rain or snow into the enclosure.

Claims

1. A passive vent device for allowing air to flow from a vented enclosure comprising:

a) a base component having an outer flange surrounding a central opening;

b) a vertical wall surrounding said central opening and extending upwardly from said base component;

c) grill structure supported by said vertical wall adapted to permit air to flow through said central opening and said grill structure;

d) a dome-shaped top cover having a top surface and a radiused peripheral edge defining a continuous downwardly depending wall which terminates in a bottom edge suspended over said vertical wall so that said bottom edge is spaced from said flange and said downwardly depending wall is spaced outwardly from said vertical wall to define an air flow path upwardly through said central opening, outwardly through said grill structure, downwardly between said vertical wall and said downwardly depending wall and outwardly between said flange and said substantially circular bottom edge; and

e) an angled diverter extending substantially around the periphery of said vertical wall and extending upwardly and outwardly from a vertical support defining a space between said vertical wall and said vertical support, said diverter further defining an outer edge which extends into and constricts but does not completely obstruct the air flow path between said vertical wall and said downwardly depending wall.

2. A passive vent device as defined in claim 1 wherein said diverter is mounted on said vertical wall.

3. A passive vent device as defined in claim 1 wherein said vertical wall is a five-sided wall.

4. A passive vent device as defined in claim 1 wherein said diverter is supported on an intermediate structure which surrounds said vertical wall.

5. A passive vent device as defined in claim 4 wherein said intermediate structure defines vertical sides positioned substantially parallel with said vertical wall.

6. A passive vent device as defined in claim 4 wherein said intermediate structure defines vertical sides positioned substantially parallel with and spaced from said vertical wall.

7. A passive vent device as defined in claim 6 wherein said top cover is secured to said base component with a plurality of posts which extend from said top cover through grooves in said vertical sides and mate with post receiving openings in said base component.
