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: An inertial barrier includes a standard size plastic container and a single size insert that is supported by a ledge inside the container for supporting different amounts of sand or other dispersible granular energy absorbing material thereon to achieve different barrier weight configurations. The insert has an axially upwardly, radially inwardly extending top wall that may be generally frustoconically shaped and is made of a suitable plastic material that permits some downward flexing of the insert inside the container as the weight of the material that is placed on the insert builds up, causing the sides of the insert to expand and push radially outwardly against the container side wall, preventing the material from leaking past the insert inside the container. Axially extending ribs may be provided in the container side wall for increased strength and rigidity.

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: 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 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 one-piece wood rivet having a first upper portion and a second lower portion is disclosed for use in adjustably securing a first piece of wood to a second piece of wood. A typical application of the rivet is the adjustment of a door threshold assembly. The first upper portion of the one-piece wood rivet includes a head and a flange. The second lower portion of the one-piece wood rivet includes a threaded shank which mates with a nut affixed to the second piece of wood. The head of the first upper portion of the one-piece wood rivet includes a lip which is deformable into a countersunk bore in the first piece of wood. The one-piece wood rivet resides substantially in a bore which extends through the first piece of wood. The one piece wood rivet is rotatable within the bore of the first piece of wood and is secured to the first piece of wood by its flange and the deformed lip. The second piece of wood includes a bore therethrough and a nut having threads affixed to the second piece of wood.
