Abstract
A retro-reflective roadway marker is generally comprised of a one-piece housing, having integrally molded retro-reflective faces. The reflective faces having outside surfaces with abrasing reducing raised members and inside surfaces of light reflecting elements that are preferably formed from three mutually intersecting surfaces. In one form the reflective elements within the housing are integrally molded with partition walls, dividing the reflective elements into small cells, each cell with a plurality of the reflective elements functioning independently without being encapsulated by the filler material.
Claims6
A reflective pavement marker comprising an integrally molded multisided hollow housing made of organic resinous material which has at least one side formed to be reflective face, said reflective face having an outside surface including rhombic shaped raised load bearing portions defining planar surfaces of a plurality of rhombic shaped cells, said cells adapted to intercept light from oncoming vehicles, said rhombic shaped cells each having an inside surface comprising at least one light reflecting element, said at least one element having three mutually intersecting surfaces, said inside surfaces of the rhombic shaped cells being divided by partition and load carrying walls which provide means to isolate and seal said at least one reflective element within each cell from adjacent cells, a backing sheet adhered to said partition and load carrying walls, said backing sheet made of organic resinous material, the interior of the housing being completely filled with thermosetting material and said thermosetting material supporting the backing sheet.
