Floating Flapper Valve
US Patent:
8584411, Nov 19, 2013
Filed:
Nov 16, 2011
Appl. No.:
13/297871
Inventors:
Michael D. Mitchell - Woodstock GA, US
Assignee:
Alcoa Inc. - Pittsburgh PA
International Classification:
E06B 7/14
US Classification:
52209, 523021, 523026, 523027, 527411
Abstract:
An apparatus for increasing the insulation value of a window system with a weep hole includes a flapper valve with a buoyant flap articulating relative to a non-moving portion. The flap is positioned on the window frame over the weep hole proximate the inside of the structure in which the window system is installed and the non-moving portion is attached to the window frame. The flap may be held against the frame around the weep hole by gravity and/or by the elastic memory of a portion of the flap, such as a plastic hinge. The flapper valve is closed when dry to diminish the flow of ex-filtration through the weep hole, but opens in response to being flooded with water due to the buoyancy of the flap, opening the weep hole and allowing the water to drain.
