Ventilation screen

摘要

A wall ventilation screen to be used in exterior walls of buildings or vehicles for protecting against rain water and other elements while simultaneously enabling air flow. The screen includes a plurality of air passages that enable air flow from one side of the screen to the other but preferably without linear communication between both sides through the air passages. The air passages present an upwardly traveling trajectory from an exterior or exposed space to a protected space, preferably with lateral changes of direction as well. Therefore rain water that comes directly from precipitation or splashing from an adjacent surface cannot reach a protected space. The geometry of the air passages provides protection against other environmental or man made elements.

1. A wall ventilation screen for use in exterior walls of buildings or vehicles for protecting from rain and other elements while simultaneously enabling air flow;
said wall ventilation screen being substantially vertical; said wall ventilation screen comprising a plurality of air passages through said screen from a first side of said screen, facing an exposed space, to a second side of said screen, facing a protected space; said air passages having a first opening on said first side of said screen, facing substantially downwardly, and a second opening on said second side of said screen, above a horizontal plane through said first opening, said air passages being shaped such that there is substantially no straight-line path through said screen via said air passages.
