Abstract
A room ventilation system, apparatus, and method enable a user to selectively ventilate a room, and incorporate the use of a tubular vent assembly. The tubular vent assembly has an apertured outer tube construction, and an apertured inner tube construction. The outer tube construction has fixed apertures. Upper convex surfacing of the outer tube construction is fixedly attached to an upper assembly-fixing construction, and lower convex surfacing is fixedly attached to a lower assembly-fixing construction. The inner tube construction has rotatable apertures insofar as the inner tube construction is rotatable relative to the outer tube construction for aligning the rotatable apertures with the fixed apertures for selectively enabling an air current to pass intermediate the room interior and the room exterior for ventilating the room interior. A lever arm and a lever-letting slot provide the user with cooperable structure for selectively adjusting the rotatable apertures.
