Abstract
A system to overcome the visual aberration of spherical automotive rear view mirrors, related to the distance between vehicles, requires no measurement or mathematical skills. The system includes means for visually determining the curvature of a mirror, and templates for the proper placement of etched film strips which frame a safe return target area on the mirror. This target area is an indicator of when a vehicle seen in the mirror is at a safe distance behind the vehicle with the marked mirror.
Claims5
A method of marking a spherical automotive rear view mirror with a safe to return target area comprising the steps of determining the curvature of said mirror by conforming a coded mirror comparitor to the curvature of said mirror, selecting a coded spacer template whose code corresponds to said coded mirror curvature comparitor, temporarily fastening said spacer template to said mirror with masking tape, adhering frosted crystal film on said mirror in vertical relationship at the left and right edges of said template and then removing said template, said adhered films on said mirror forming a safe to return target to overcome the visual aberrations common to said spherical automotive rear view mirror.
A system for forming a safe return target area on a spherical automotive rear view side mirror comprising comparison means to determine the curvature of said spherical mirror, said comparison means having located thereon coded identifiers corresponding to said curvature of said mirror referring to a selected spacer template having the same coded identifier located thereon, said template having left and right edges and a center portion;
- said center portion having perforations therethrough, said perforations acting to supply an area for the temporary adhering of said selected template to said mirror wherein the selected template is one of said spacer templates which has the same coded identifier as the comparison means corresponding to said mirror's curvature, said left and right edges of said selected template acting to define the location of vertical frosted left and right film strips, said left and right film strips being adhered to said spherical mirror at said left and right selected template edges, respectively, said temporarily adhered selected template being removed, said area between said adhered vertical frosted film strips defining said safe return target area.
