Patent ID: 7775009

Claim:
A system for providing a decorative covering on a support surface, said system comprising: a plurality of panels, each of said panels having a top and a bottom and first and second ends and including; a mounting flange adjacent said top, a first row of decorative portions disposed between said top and bottom to define a first front face and a second row of decorative portions disposed between said top and bottom to define a second front face, a riser connecting said first and second rows such that said first row is in a stepped relationship with said second row, a first overlap portion adjacent said first end and a second overlap portion adjacent said second end wherein said first overlap portion is configured for overlapping said second overlap portion of a horizontally adjacent panel mounted to the support surface, and a first interlock having an inner surface extending from said riser at said first end and a second interlock having an outer surface extending from said riser at said second end, said inner and outer surfaces being defined as abutting surfaces sloped upwardly toward said top at an acute angle relative to at least one of said first and second front faces wherein said inner surface overlies and abuts said outer surface of said horizontally adjacent panel at said acute angle to secure said interlocks together and reduce relative movement between said panels when mounted to the support surface.
