Abstract:
1. A ceiling vent assembly comprising: a frame comprising a pair of opposed end panels and a pair of opposed side panels; said side and end panels each having an upper edge and a lower edge; said frame being open at a top and a bottom thereof; at least one louver mounted in said frame to pivot about a pivot axis between an open position wherein air can flow through and exit said ceiling vent assembly and a closed position wherein the open bottom of said frame is substantially closed to substantially prevent air from flowing through and exiting said ceiling vent assembly; said louver having an inner edge, an outer edge, opposed end edges, an upper surface and a lower surface; said louver upper surface defining a continuous concave curve which extends substantially between the opposed end edges and substantially from said inner edge to said outer edge of the louver; said louver lower surface having a first major portion extending from the inner edge of said louver substantially toward the outer edge of the louver and a second edge portion which extends from the first portion to the outer edge of the louver; the first portion having a curvature substantially matching the curvature of the louver upper surface to define a major portion of the louver having a generally constant thickness; said second portion of said louver lower surface defining a sloped surface to such that said edge portion of said louver has a decreasing in thickness; and wherein said louver is mounted in said frame such that air exiting said ceiling vent assembly travels along said concave upper surface of said louver; said curvature of said louver upper surface being shaped and configured to direct air flow generally outwardly and horizontally along a ceiling in which said vent assembly is mounted and said airflow moving away from the ceiling vent assembly when said louver is disposed in an open position.
