Abstract: A portable highway warning device includes any number of elongated rumble strips each fabricated of a suitable flexible polymeric material. Embedded within each rumble strip are a plurality of laterally spaced metal plates or bars to provide ballast to each rumble strip. The metal plates or bars run transversely across the width of each rumble strip with sufficient spacing therebetween to permit each rumble strip to be rolled up lengthwise from end to end when not in use.

Abstract: Plastic molded uprights and/or light and flag mounts may include stepped upper ends for mounting of a light thereon and/or laterally spaced apart oppositely downwardly angled flag mounting holes extending at least partway therethrough adjacent the upper ends thereof. One or more pairs of integral molded, axially spaced apart flanges may protrude outwardly from one of the front and back walls of the uprights for aiding in locating and supporting one or more barricade boards between respective pairs of flanges.

Abstract: A barrier includes a housing having a front wall and an opposing back wall each extending between opposing sidewalls. The housing also includes a floor and an interior surface bounding a chamber, the chamber communicating externally through an inlet opening. A first inset projects into the chamber from the front wall so as to form a recessed pocket on the front wall. A second inset projects into the chamber from the back wall so as to form a recessed pocket on the back wall. The first inset and the second inset are connected together within the chamber so that the chamber encircles the connection.

The housing also includes a floor and an interior surface bounding a chamber, the chamber communicating externally through an inlet opening. A first inset projects into the chamber from the front wall so as to form a recessed blind pocket on the front wall. A second inset projects into the chamber from the back wall so as to form a recessed blind pocket on the back wall. The first inset and the second inset are connected together within the chamber so that the chamber encircles the connection.

Abstract: Plastic blow molded board-like members include a plurality of longitudinally extending, laterally spaced aligned channels/grooves in opposite sides of the members. Each of the channels has closely spaced apart side walls and inner end walls. The inner end walls of aligned channels in opposite sides of the member are joined together to provide a relatively high strength reinforced core. The ends of the members are completely closed during the blow molding process for increased strength and to keep out dirt and moisture.

Abstract: A base support for supporting a post or other upright in a generally upright position includes an elongated base member having a wider portion intermediate its length containing a mounting hole for receipt of an end portion of the post or other upright. A carrying handle may be provided on a side wall of the base member adjacent one end of the wider intermediate portion.

Abstract: A traffic channelizer device includes a deformable hollow plastic drum that may be ballasted by a drop over ballasting collar or by a base having an upper portion that may be releasably retained within the open bottom of the drum by a plurality of circumferentially spaced radially inwardly extending locking fingers adjacent the bottom edge of the drum that releasably engage a groove in the upper portion of the base. An intermittent stacking rim may be provided at the top of the drum to prevent overstacking of a plurality of such drums. Also the intermittent stacking rim may be used to prevent rotation of a portable sign assembly relative to the drum and keep the portable sign assembly from inadvertently sliding up off the drum top.

Abstract: A portable sign assembly includes one or more sign supports attached to the outer surface of a flexible band that may be adjustable to fit different diameter drums. Each sign support may have a substantially planar front face to facilitate attachment of a panel assembly to the sign support. The panel assembly may comprise one or more sign panels. If there is more than one sign panel, a drop panel having a greater vertical height than the sign support may be attached to the sign support to provide a larger attachment area for the sign panels.
