Patent ID: 6883336

Claim:
An air-conditioning condensate drainage system for the roof structure of buildings, comprising: at least two elongate strips of material extending from at least two roof mounted air-conditioning units along the roof structure and having an isolation membrane defining a bottom surface for assembly to a roof membrane and having an upper surface and having side edges; a pair of ridges being located along said side edges of said elongate strip of material and each having a generally triangular cross-sectional configuration, said pair of ridges being disposed in spaced relation with one another and cooperating with said isolation membrane to define an air-conditioning condensate drainage channel between said ridges conducting air-conditioning condensate from the air-conditioning units; at least one collector membrane of generally triangular configuration having side edges and defining a condensate collection basin; edge ridges projecting upwardly from said side edges of said collector membrane and defining at least one inlet opening within which an end portion of at least one of said two elongate strips of material is located, said edge strips further defining an outlet opening of said condensate collection basin.
