  • Patent number: 6817805
    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.
    Type: Grant

  • Patent number: 6769207
    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.

  • Patent number: 6733205
    Abstract: Guardrail delineators include a flag portion and a depending leg portion. One side edge of the leg portion has a notch axially spaced from the flag portion. The top surface of the notch is engageable with a top edge of the guardrail or a top edge of the support structures for the guardrail for positioning the flag portion a predetermined height above the guardrail. The one side edge of the leg portion axially outwardly of the notch extends perpendicular from the inner end of the notch and is engageable with the back side of the guardrail or support structures for providing proper vertical alignment of the delineators with respect to the guardrail.

  • Publication number: 20030091387
    Abstract: Guardrail delineators include a flag portion and a depending leg portion. The front edge of the leg portion has a notch axially spaced from the flag portion that is engageable with a top edge of the guardrail or a top edge of the support structures for the guardrail and the front edge of the leg portion axially outwardly of the notch is engageable with the back side of the guardrail or support structures for allowing an installer to easily maintain both vertical and horizontal alignment of the delineators.

  • Patent number: 6182600
    Abstract: Traffic channeling device includes a delineator stem having hollow upper and lower portions, the upper portion being stepped inwardly along its axial length to form sequential stepped surfaces from the bottom to the top of the upper portion, and the lower portion being frustoconically shaped. Adjacent the bottom of the delineator stem is a radial flange portion which resists pullout of one or more ring-shaped base members placed over the top of the delineator stem to act as ballast for the delineator stem. The base members include a non-circular raised portion and a correspondingly sized recessed portion such that when one base member is stacked on top of another, the recessed portion of one base member will receive the raised portion of the other base member and resist relative rotatable movement between the base members.
