  • Patent number: 4791746
    Abstract: A display device includes a component in the form of a plate bearing one or more display indicia on one plate surface and having a passage extending through the plate adjacent the display indicium. An integral light-transmissive element is fixedly secured in the plate passage and has a first lensed surface at one end adjacent the display indicium. At its opposite end, the light-transmissive element defines both a second lensed surface and a flat surface in abutting relation to a stepped part of the passage within the plate. The first lensed surface is convex relative to the light-transmissive element and the second lensed surface is concave relative to the light-transmissive element. The element, comprised of a polycarbonate film which is highly resistant to impact damage, is of dimension relative to the passage such that an interference-fit exists therebetween.
