Abstract
Abstract A molded corner protector which is attached to a second structure includes an enclosure having a pie shaped top surface and a pair of curved side walls extending downwardly from the top surface. The enclosure is spaced from the second structure along an air pocket defined by the enclosure. The protector preferably is constructed from a relatively soft, pliable rubber like plastic substance and is designed so that the enclosure meets the second structure along the outboard edges of the enclosure. Means for attaching the protector to the second structure preferably include both double sided foam tape attached to at least one lip formed within the air pocket, and a suction cup integrally formed with the top surface of the protector enclosure on the air pocket side thereof.

Claim 8
Dependent Claim
106 words
A corner protector which is applied to the corners of a second structure, comprising: an enclosure including a relatively flat top surface area and a curved portion terminating in an arcuate edge, a first curved side wall, and a second curved side wall, said first and second side walls extending downwardly from said top surface area and terminating in an edge, each edge of said side walls abutting said second structure in the intermounted position of said protector, said enclosure defining an air pocket with said second structure; and a suction cup mounted to a bottom side of said top surface area in said air pocket.
Claim 9
Dependent Claim
106 words
A corner protector which is applied to the corners of a second structure, comprising: an enclosure including a relatively flat top surface area and a curved portion terminating in an arcuate edge, a first curved side wall, and a second curved side wall, said first and second side walls extending downwardly from said top surface area and terminating in an edge, each edge of said side walls abutting said second structure in the intermounted position of said protector, said enclosure defining an air pocket with said second structure; and a suction cup mounted to a bottom side of said top surface area in said air pocket.
Claim 10
Dependent Claim
154 words
In a corner protector having a one piece body adapted to mate with a corner of a second structure, said corner protector including a top surface, a first side wall and a second side wall, the improvement comprising an air pocket between said second structure and said corner protector, said air pocket being defined by a sloping end wall along one edge of said top surface area so that said top surface area lies in a plane above the plane of a surface of said second structure, and said first and second side walls having a radius of curvature imparted to them between said top surface and a terminal edge of said side walls so that said side walls are spaced from said second structure except along the engagement area of said terminal edge, and means for attaching said corner protector to said second structure, said attaching means being mounted in said air pocket.
