Abstract: An edge guard of generally U-shaped cross section for fitting onto an edge comprises an insert having a cross section corresponding to the general U-shaped cross section of the edge guard and non-metallic material encapsulating said insert. The insert is an extrusion, either metal or plastic, and the non-metallic encapsulating material is a plastic, preferably a co-extrusion co-extruded onto the insert. The insert has a sculptured, or fluted, form throughout. Various sculptured forms are disclosed. The non-metallic encapsulating material may be colored as desired to impart a desired color to the edge guard.

Abstract: An edge guard formed from a metallic strip to a generally U-shaped cross section wherein the base of the U has a generally semi-circular shape and beads at the distal ends of the legs are inwardly offset. An insulating liner may also be laminated to the metal strip before roll forming to the U-shape.

Abstract: An improved method of manufacturing an insulated metallic edge guard, such as a door edge guard, comprises applying an insulating layer to one side of the metal strip which remains on the strip for protecting and insulating the edge guard from the object on which it is installed when in use, applying a protective layer to the opposite surface of the metal strip for the purpose of protecting the appearance of the strip during manufacturing, forming the laminated metal strip into a U-shaped cross section of desired configuration and then stripping the protective layer which is on the exterior of the U-shaped cross section from the door edge guard to expose the exterior of the metal to view.

Abstract: Decorative trim for use such as a body side molding on an automotive vehicle comprises a metal strip with a vinyl insulation applied to one side of the strip. Beads are formed along the longitudinal margins of the strip by turning them inwardly from the main body of the molding so that when applied to the body of an automotive vehicle the main body of the molding is set outwardly from the vehicle body. The formation of the beads stiffens the metal and the beads are disposed against the body of the sheet metal. Various attachment procedures may be used including adhesive between the beads and the vehicle, and the use of mechanical fasteners is also possible.

Abstract: An edge guard of the type comprising a metal strip formed into a generally U-shaped transverse cross section having inner and outer legs with beads at the distal ends of the legs via which the edge guard is self-retained on the edge of an object when installed thereon. The cross section has a generally semi-circular contoured base which joins with the two legs. One leg includes an inward offset so that its bead is disposed in inwardly offset relation to the corresponding end of the base. The other leg comprises a straight segment extending straight from the other end of the base to the corresponding bead. The base comprises segments having different radii of curvature. In the free condition of the edge guard, the inner faces of the beads, which bear against opposite sides of an edge when the edge guard is installed thereon, are disposed in non-parallel relation.

Abstract: An ornamental and protective door edge guard comprises a metal strip of generally U-shaped cross section having inner and outer legs via which the edge guard is self-retaining on the edge of a vehicle door.

Abstract: A universal edge guard comprises a generally U-shaped metal channel having inner and outer legs with the cross section of the channel being formed into a generally semi-circular base with beads at the ends of the inner and outer legs being inwardly offset. A pattern of notches is formed in the inner leg with the notches extending from the bead along the inner leg and into the semi-circular base terminating just slightly beyond the mid-point of the base. The pattern of notches has uniformly sized notches with the notches being equally spaced apart. The preferred pattern has the notches at about one-half inch spacing and the notches about three-sixteenths inch in width. The construction allows the edge guard to be contoured to the contour of an edge without the use of additional manufacturing procedures to conform the edge guard to the desired cross section. The edge guard may also be readily cut to length by severing at one of the notches.
