Abstract
Abstract A decorative plastic trim strip in which a formed metal surfaced foil is embedded in a light-transmitting plastic sheath. The foil is provided with a colorant stripe on part of its surface to produce contrasting color effects. The surface of the plastic sheath is shaped differently from the confronting surface of the formed foil to change the apparent width of the foil when viewed through the sheath.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
An elongate decorative trim strip, comprising an elongate light-reflective foil strip encapsulated in a light-transmitting plastic sheath of equal length to protect said foil strip from ambient conditions, said equal length being many times greater than any cross-sectional dimension of said plastic sheath, said plastic sheath providing a raised medial rib merging downwardly along concave exterior surfaces into a lateral body portion on each side and said foil strip comprising a generally U-shaped central dome centrally located in said rib and having flanges at the edges of said central dome, which flanges extend laterally into said lateral body portions, the concave surfaces of the plastic sheath producing apparent distortions of the foil strip as viewed from the exterior.
Claim 2
Dependent Claim
118 words
