Abstract

Abstract An edge guard trim for an automobile door edge or the like comprising a sheet metal strip roll formed into a generally U-shaped cross-sectional configuration so as to provide a bight portion and a pair of leg portions extending therefrom terminating in free ends. The free ends of the leg portions are rounded off at least along their inner corners. An extrudable thermoplastic insulating material is extruded in covering relation to the free ends of the leg portions in sufficient quantity to enable the metal strip to be installed on a door edge in scratch free fashion and in covering relation to the interior surfaces of the leg portions and bight portion in sufficient quantity to provide a desired insulation between the metal strip and the door edge during use. The exterior surfaces of the leg portions and the bight portion are smooth and free of insulating material so as to present an exposed metallic visual appearance.

Claim 1
Independent Claim 210 words
An edge guard for an automobile door edge or the like comprising a sheet metal strip roll formed into a generally U-shaped cross-sectional configuration so as to provide a bight portion and a pair of leg portions extending therefrom terminating in free ends, one of said pair of leg portions constituting an exterior leg portion for guarding the exterior of the door edge, said exterior leg portion being of uniform one ply thickness, the free end of said exterior leg portion being defined by the edge of the one ply thickness of said exterior leg portion and an extrudable thermoplastic insulating material extruded in covering relation to the interior surfaces of said leg portions in sufficient quantity to enable the metal strip to be installed on a door edge in scratch free fashion and in covering relation to the interior surface of the bight portion in sufficient quantity to provide a desired insulation between the metal strip and the door edge during use, said extrudable thermoplastic insulating material being extruded in covering relation to the free end of said exterior leg portion, the exterior surfaces of said exterior leg portion and said bight portion being smooth and free of insulating material so as to present an exposed metallic visual appearance.
Claim 2
Dependent Claim 210 words
An edge guard for an automobile door edge or the like comprising a sheet metal strip roll formed into a generally U-shaped cross-sectional configuration so as to provide a bight portion and a pair of leg portions extending therefrom terminating in free ends, one of said pair of leg portions constituting an exterior leg portion for guarding the exterior of the door edge, said exterior leg portion being of uniform one ply thickness, the free end of said exterior leg portion being defined by the edge of the one ply thickness of said exterior leg portion and an extrudable thermoplastic insulating material extruded in covering relation to the interior surfaces of said leg portions in sufficient quantity to enable the metal strip to be installed on a door edge in scratch free fashion and in covering relation to the interior surface of the bight portion in sufficient quantity to provide a desired insulation between the metal strip and the door edge during use, said extrudable thermoplastic insulating material being extruded in covering relation to the free end of said exterior leg portion, the exterior surfaces of said exterior leg portion and said bight portion being smooth and free of insulating material so as to present an exposed metallic visual appearance.
Claim 3
Dependent Claim 33 words
An edge guard trim as defined in claim 1 wherein said bight portion is arcuate and said leg portions are straight and converge toward one another in the direction of their free ends.
Claim 4
Dependent Claim 24 words

Claim 6
Dependent Claim 39 words
An edge guard trim as defined in claim 2 wherein the inner corners of the free ends of said leg portions are rounded off by coining during the roll forming of the metal strip into the U-shaped cross-sectional configuration.
Claim 7
Dependent Claim 39 words
An edge guard trim as defined in claim 5 wherein the outer corners of the edges of said leg portions are also rounded off by coining during the roll forming of the metal strip into the U-shaped cross-sectional configuration.
Claim 8
Dependent Claim 39 words
An edge guard trim as defined in claim 5 wherein said metal strip has a thickness within the range of 0.38 to 0.43 millimeters and said insulating material has a thickness within the range of 0.50 to 0.62 millimeters.
Claim 9
Dependent Claim 27 words
