Abstract

An architectural trim product formed of a metal sheet material that is bent to a selected profile shape by the interaction of mating contoured die surfaces. The product has a first end that engages first edge of a mounting member and a second end that engages the opposite edge of the mounting member. The second end of the trim product includes a bent edge that grips the mounting member to securely hold thereto. The fasteners used to affix the mounting member to the building structure are subsequently covered so that no trim product fasteners remain visible.

Claims

1. A method of forming and applying an elongated horizontal transitional trim product comprising:

a) forming an elongated molded, horizontally-positioned stiffening block, comprising;

i) a flat, vertical back surface;

ii) a flat, horizontal top surface;

iii) a flat, horizontal bottom surface; and

iv) a front surface extending between an outer edge proximate said top surface and an outer edge proximate said bottom surface, and providing in its cross-sectional profile a plurality of interconnected, continuous surfaces, including both flat and curved, vertical and horizontal surfaces;

b) fixedly securing said molded horizontally-positioned stiffening block directly to a flat, vertical surface of said building;

c) forming an elongated, horizontal deformable metallic sheet terminating in respective upper and lower end sections located above and below a central section and characterized by said central section providing, in its cross-sectional profile, a plurality of interconnected, continuous surfaces, which mate and snugly fit with the cross-sectional profile of said stiffening block, said central, upper, and lower end sections bring shaped so as to enable said sheet, prior to installation of other support means, to be installed on, supported by, and closely fitted to said stiffening block; and

d) mounting said sheet onto said stiffening block by utilizing the shape of said central upper, and lower end sections of said sheet to support and maintain said sheet on said stiffening block prior to installation of other support means.

2. The method of claim 1, wherein said upper-end section of said sheet is formed in a U-shape adapted to receive and snugly fit an exposed edge of a horizontal member secured to said building outwardly of said trim product and including the step of engaging a said horizontal member with said U-shaped upper-end section.

3. The method of claim 1, wherein said sheet of deformable metallic material is chosen from aluminum, copper and steel.

4. The method of claim 1, wherein said molded stiffening block is made of foamed plastic resin.
