Decorative wall covering with upward movement panel interlock system

摘要

A wall covering comprising a plurality of plastic panels each having a body portion formed with rows of simulated building elements. The panels are mounted on a support surface with a lower marginal edge region of one panel overlying an upper marginal edge region of a previously mounted panel in a lower course and with a side marginal edge region of one panel overlying the side marginal edge region of a previously mounted adjacent panel in the same course. The marginal edge regions are provided with interlocks which engage and secure both the overlapping upper and lower marginal edge regions and the overlapping side marginal edge regions as an incident to upward movement of the panel relative to the underlying previously mounted panels. In the illustrated embodiment, the overlying lower marginal edge region and side marginal edge region of each panel are formed with upwardly directed locking flanges which are respectively engageable with downwardly directed flanges on the upper marginal edge region and apertures in the side marginal edge region of the underlying panels.
