US Patent 7694478 Panel attachment system

A panel attachment system (10) comprising a plurality of covering panels (12), a plurality of retaining members (16) to hold the panels (12), and a plurality of mounting structures (18) to secure the retaining members (16) to a surface (20). The panels (12) are held to the retaining members (16) through the use of protruding locking members (32) formed on the panels (12) which interlock with a slot (48) formed on the retaining member (16). The panels (12) may be coupled to the retaining members (16) without the need for precise alignment, thereby expediting the installation of the surface (20). The retaining members (16) additionally contain a drainage channel (50) to carry water and other debris away from the surface (20).
