Abstract

Abstract A ventilator device in the form of a half dome having an open, screened face surmounting a sloping header with an internal, hinged entrance located below the header and a slotted U-tube having dual funnel shaped intakes facing in the direction of the screened face, the slotted U-tube enabling air forced therein via the funnel intakes to disperse moisture within the device to be exhausted other than through the air passageway over which the ventilator device is mounted with an opening in a vehicle to be ventilated. The ventilator device may be molded or otherwise formed, and the material of which it is made may be opaque or translucent - in the latter case providing illumination from daylight sources as well as ventilation.
