Patent ID: 6955019

Claim:
A wall covering for mounting on a support surface comprising: a plurality of panels each having a body portion formed with simulated building elements; said panels each having upper and lower marginal edge regions and first and second side marginal edge regions; said panels being mountable on said support surface in a plurality of horizontal courses with at least some of said panels in a first horizontal course having a lower marginal edge region overlying an upper marginal edge region of a previously mounted panel in a second course positioned below the first horizontal course and with at least some of said panels in each course having a first side marginal edge region overlying a second side marginal edge region of an adjacent previously mounted panel in the course; and said upper and lower marginal defining interengageable interlocks for positively securing together overlapping upper and lower marginal edges: said first marginal edge region of each panel having at least one upwardly directed interlock flange located intermediate the upper and lower edge regions engageable with the second side marginal edge region of an underlying adjacent previously mounted panel in the same course as an incident to upward vertical movement of the panel relative to the adjacent previously mounted panel for positively securing the overlapping side marginal edge regions together when the panels are mounted on the support surface.
