Abstract

A plastic molded wall covering that includes a plurality of one piece plastic molded corner moldings mounted in a vertically stacked array. The corner moldings each have a pair of front panels disposed at an angle to each other and formed with simulated building elements, such as hand laid stone. The corner moldings have respective upper and lower interlock devices and internal support and reinforcing walls extending rearwardly of the front panels in interconnecting relation to the interlock devices. The internal support and reinforcing walls have a curved serpentine configuration with a curved junction line with the respective front panels such that any plastic molded sink mark exposed on a front side of the front panels from the integrally formed internal walls similarly is undulating so as to blend into the simulated building elements and not detract from its natural appearance.

Claims18

Dependent claims

A plastic molded wall covering for a pair of wall surfaces that form a corner comprising:

a plurality of one piece plastic molded elongated wall panels each formed with a plurality of simulated building elements, said wall panels being mounted on said wall surfaces in a plurality of horizontal courses with side marginal edge regions of adjacent panels in overlying relation to each other and with a lower marginal edge region of each wall panel in partially overlying relation to an upper marginal edge region of a previously mounted course of said wall panels,
a plurality of one piece plastic molded corner moldings in a vertically stacked arrangement each laterally adjoining the wall panels of horizontally adjacent courses, said corner moldings having a pair of front panels disposed at an angle to each other corresponding substantially to the angle of the wall surfaces that define the corner upon which the corner molding is mounted, said corner molding front panels each being formed with simulated building elements,
at least two internal walls, each internal wall being integral with an extending rearwardly of a respective one of said front panels at a location intermediate opposite sides of the front panel, and each internal wall joining a rear side of said front panel with a curved juncture line such that any plastic molded sink mark exposed on a front side of said front panel from said integrally formed internal wall does not extend in a straight line in which said walls each have a curved undulating configuration which define a curved undulating junction line with the corner molding panel from which it depends.

A plastic molded wall covering for a pair of wall surfaces that form a corner comprising:

a plurality of one piece plastic molded elongated wall panels each formed with a plurality of simulated building elements, said wall panels being mounted on said wall surfaces in a plurality of horizontal courses with side marginal edge regions of adjacent panels in overlying relation to each other and with a lower marginal edge region of each wall panel in partially overlying relation to an upper marginal edge region of a previously mounted course of said wall panels,
a plurality of one piece plastic molded corner moldings in vertically stacked arrangement each laterally adjoining the wall panels of horizontally adjacent courses, said corner moldings having a pair of front panels disposed at an angle to each other corresponding substantially to the angle of the wall surfaces that define the corner upon which the corner molding is mounted, said corner molding front panels each being formed with simulated building elements and being mounted in overlying relation to an adjacent wall panel,
said corner moldings each having an upper interlock device adjacent an upper end of said corner molding and a lower interlock device adjacent a lower end of said corner molding for interlocking engagement with an upper interlock member of an underlying previously mounted corner molding in the vertically stacked arrangement,
said upper interlock device including an upstanding interlock pin, said lower interlock device including an interlock pin receiving aperture for receiving the interlock pin of an underlying corner molding in the stacked arrangement, and
said upper and lower interlock devices having engageable alignment surfaces for aligning the corner moldings in stacked relation to each other as an incident to mounting,
wherein said corner moldings include frangible locating pins extending rearwardly of said corner molding panels adjacent a lower end thereof for locating the corner moldings in vertically stacked relation to each other as an incident to mounting.
