Abstract:
1. A room ventilation system for enabling a user to selectively ventilate a room, the room ventilation system comprising, in combination: a wall-based, assembly-holding construction, the wall-based, assembly-holding construction dividing a room interior from a room exterior, the assembly-holding construction comprising a tube-engaging upper assembly and a tube-engaging lower assembly, the tube-engaging upper assembly comprising downwardly facing inner surfacing, the tube-engaging lower assembly comprising upwardly facing inner surfacing opposing the downwardly facing inner surfacing; and a tubular vent assembly, the tubular vent assembly having an apertured outer tube construction and an apertured inner tube construction, the apertured outer tube construction having upwardly facing outer surfacing, downwardly facing outer surfacing, room-exterior-side fixed apertures and room-interior-side fixed apertures, the upwardly and downwardly facing outer surfacing of the apertured outer tube construction being respectively shaped for mating with downwardly and upwardly facing inner surfacing of the tube-engaging upper and lower assemblies, the upwardly facing outer surfacing thus being fixedly attached to the downwardly facing inner surfacing, and the downwardly facing outer surfacing thus being fixedly attached to the upwardly facing inner surfacing, the apertured inner tube construction comprising thermal insulation means, room-exterior-side rotatable apertures and room-interior-side rotatable apertures, the apertured inner tube construction being rotatable relative to the apertured outer tube construction for aligning the room-exterior-side and room-interior-side rotatable apertures with the room-exterior-side and room-interior-side fixed apertures for selectively enabling an air current to pass intermediate the room interior and the room exterior for ventilating the room interior, the thermal insulation means being defined by an upper layer of material insulation and a lower layer of material insulation, the upper and lower layers of material insulation having opposed parallel surfacing, the opposed parallel surfacing for enhancing air flow intermediate the room interior and the room exterior when the apertured inner tube construction is in an open state, the thermal insulation means for slowing heat transmission intermediate the room interior and the room exterior when the apertured inner tube construction is in a closed state.
