Abstract
A reflective pavement marker having integrally molded one-piece structural body with multiple hollow cavities that are open only at the top reflective faces of the marker, two arcuate sides and integrally sealed planar base surface with textures and discontinuous grooves. This marker provides a device to enhance agglutination to the roadway, improve resistance to flexural stresses due to automobiles impact forces; this is accomplished by maximizing the base surface area for adhesive wetting parameter. The reflective plates are welded on wedge like tops of the partition walls separating hollow cavities from each other. The body can be made of various recycled or virgin structural plastics with high impact resistance and UV stability.
Claims23
A reflective roadway marker having a one piece body with at least one reflective plate means for attachment, said one piece body comprising:
- multiple hollow cavities, two arcuate sides, a top portion, a sealed planar base, said sealed planar base having a bottom surface with textured, disontinous grooves and two inclined planar faces, each of said planar faces having a planar recessed portion where the open ends of hollow cavities are located and where one reflective plate means can be attached, said planar recessed portions having the top ends of load carrying partition walls defining said hollow cavities within one said piece body, each of said top ends of load carrying partition walls is having a wedge shaped top surface, said wedge shaped top surfaces are being adopted for structural enhancement and to maximize the air gap areas at the open ends of said hollow cavities, said load carrying partition walls each having inwardly formed angle of about 2 to 5 degrees with respect to the center line of said corresponding hollow cavity;
- and
- reflective plate means for attachment to the top portions of said wedge shaped top surfaces and periphery of said planar recessed portion of said inclined planar faces of said one piece body, said reflective plate means having inside surface with multiple of cube-corner reflective elements and planar outside surface, said inside surface sonically wedded to said wedge shaped top surfaces thereby fusing a portion of said cube corner reflective elements to said wedge shaped top surfaces thereby defining cell like inside surface upon the reflective plate means, each said cell having the remaining cube corner reflective elements, said planar outside surface can be divided into slightly recessed cell like planar surfaces.
A retro reflective roadway marker comprising:
- one piece structural body and at least one reflective plate attachment, said one piece body integrally formed comprising:
- a sealed planar base surface with textured sincontinous grooves, two arcuate sides, a top side having two hump portions each having a concave curve shaped reflective face, a plurality of hollow cavities integrally formed within said one piece body, said reflective face having the top planar open ends of said hollow cavities within a planar recessed portion, said hollow cavities being defined by load carrying partition walls having recessed wedge shaped top surfaces for reflective plate attachment, said two hump portions connected by a center concave recess portion.
A roadway marker comprising of one piece structural body and one reflective plate attachment, said one piece structural body is formed having spherical shaped upper surface, said upper surface integrally formed with inwardly tapered load carrying partition walls defining multiple hollow cavities integrally within said one piece body, said load carrying partition walls having wedge shaped top surfaces within a recessed portion of said spherical shaped upper surface of said one piece body, said one piece body having an integrally sealed planar base surface with raised pens.
A retro reflective roadway marker comprises:
- a structural body formed by welding two identical parts integrally connected by a tear able thin wedge, each of said part having a top surface, a textured and sealed planar base surface, two multi-angled sides, one inclined planar face surface with a planar recessed portion, a beaded and hollowed backside forming perpendicular angle with respect to said sealed planar base surface and integrally formed load carrying partition walls defining multiple hollow cavities within each of said part, said load carrying partition walls having open ends with wedge shaped top surfaces within said planar recessed portion of said part;
- and
- reflective plate means for attachment to said wedge shaped top surfaces of said load carrying partition walls defining multiple hollow cavities within said planar recessed portions of said part, said reflective plate means having inside surface with multiple of cube corner reflective elements, said reflective plate means having an outside surface with planar transparent surface to intercept light from incoming traffics.
