Abstract

Abstract A wall guard for protecting wall corners or other wall areas subject to abuse including an elongate resilient strip to be mounted directly upon completed wall surfaces. The elongate strip includes a central portion conforming generally to the wall area to be protected, the central portion being supported in spaced relation to the underlying wall surface. The strip includes inturned edges defining concealed channels near the edges which receive retainers mounted upon the protected wall portion. The retainers, which include portions extending into the channels, are entirely masked by the protective strip to give a clean, neat appearance. The retainers may conform to the underlying wall section, as by forming the retainers for extension about a wall corner, in which case the retainers afford easy alignment of the strip and protected wall area. At the ends of the strip, a combined retainer and cap engages the strip to close the space defined between the strip and wall.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 305 words
A wall corner protector arrangement including a generally right angular elongate outer abuse-resistant resilient member extending along and protecting a protruding corner of a wall, the resilient member having inturned edges defining interior channels at each side of an angular outer central section of the resilient member, interior retainers including mounting straps connected to the wall beneath the resilient member, said straps including wall engaging portions terminating at each side in extensions connected to said straps and supported outwardly away from the wall engaging portions of the straps and laterally with respect to the resilient member, said extensions being received into the channels of the resilient member, the outward positioning of the extensions with respect to the wall engaging portions forming recesses beneath the extensions, said recesses receiving said inturned edges slidably therein between the extensions and the wall surface, said central section of the resilient member being spaced outwardly from the underlying wall surface, a cap member having an external portion and an internal portion relative to the resilient member, the external portion extending across the width of the resilient member at the end of the resilient member and defining a shoulder substantially perpendicular to the outer surfaces of the resilient member to close the space between the resilient member and the underlying wall surface at the end of the resilient member, the internal portion of the cap having a mounting strap portion contacting and attached to the wall and connected with said external portion at the shoulder, and outwardly positioned extensions projecting laterally and offset from said mounting strap portion, of said cap receiving the ends of the inturned edges, said mounting strap portion of the cap being spaced inwardly from the central portion of the resilient member to permit inward flexure and return of the resilient member at and adjacent its end.
Claim 2
Dependent Claim 305 words
A wall corner protector arrangement including a generally right angular elongate outer abuse-resistant resilient member extending along and protecting a protruding corner of a wall, the resilient member having inturned edges defining interior channels at each side of an angular outer central section of the resilient member, interior retainers including mounting straps connected to the wall beneath the resilient member, said straps including wall engaging portions terminating at each side in extensions connected to said straps and supported outwardly away from the wall engaging portions of the straps and laterally with respect to the resilient member, said extensions being received into the channels of the resilient member, the outward positioning of the extensions with respect to the wall engaging portions forming recesses beneath the extensions, said recesses receiving said inturned edges slidably therein between the extensions and the wall surface, said central section of the resilient member being spaced outwardly from the underlying wall surface, a cap member having an external portion and an internal portion relative to the resilient member, the external portion extending across the width of the resilient member at the end of the resilient member and defining a shoulder substantially perpendicular to the outer surfaces of the resilient member to close the space between the resilient member and the underlying wall surface at the end of the resilient member, the internal portion of the cap having a mounting strap portion contacting and attached to the wall and connected with said external portion at the shoulder, and outwardly positioned extensions projecting laterally and offset from said mounting strap portion, of said cap receiving the ends of the inturned edges, said mounting strap portion of the cap being spaced inwardly from the central portion of the resilient member to permit inward flexure and return of the resilient member at and adjacent its end.
Claim 3
Dependent Claim 49 words
The wall corner protector arrangement according to claim 1, wherein the outer portion of the cap includes substantially perpendicular sections for extension about a right angular wall corner, and a convex curved outer surface on each perpendicular section extending from said shoulder to the surfaces of the wall corner.
