  • Patent number: 6237266
    Abstract: An evacuation route indicator includes a carpeted strip extending in an elongation direction and having direction-indicating indicia formed thereon at spaced intervals along the elongation direction. The indicia include a photoluminescent material and are formed so as to define a surface which is either recessed below or raised above the remaining surface of the carpeted strip, or a surface texture which is different from the surface texture of the remainder of the carpeted strip. Thus, the indicia are discernible both visually and tactilely in the absence of light. The indicator may also include a photoluminescent marker extending substantially continuously in the elongation direction on the carpeted strip.
