发明名称 Method of Connecting a Down Spout Extension to an Eave Trough Down Spout
摘要 <p>A method of connecting a down spout extension to an eave trough down spout. Firstly, pivotally connect a down spout extension to a lowermost end of an eave trough down spout such that the down spout extension is movable between a substantially vertical stored position and a substantially horizontal operative position. Secondly, position a spring at the connection of the down spout extension and the eave trough down spout biasing the down spout extension into the stored position. The spring tension is set such that a flow of water through the down spout provides a force to overcome the biasing force of the spring thereby moving the down spout extension to the operative position.</p>
