US Patent 7743561 Eaves trough

An eaves trough for receiving water from a structure includes an elongated sheet that extends along a longitudinal axis and extends integrally from a first longitudinal edge to a second longitudinal edge. An upper portion of the sheet at least partially overlies the structure and extends from the first longitudinal edge to a longitudinal transition. A lower portion of the sheet extends from the longitudinal transition to the second longitudinal edge. The lower portion of the sheet extends generally downward from the upper portion of the sheet at the longitudinal transition and extends under at least part of the upper portion of the sheet, such that the lower portion of the sheet defines a trough below the upper portion of the sheet. Apertures are formed through the upper portion of the sheet such that the apertures overlie the trough. The water travels from the structure onto the upper portion of the sheet and through the apertures to the trough.
