Abstract:
A traffic delineation apparatus comprising:a deformable stackable hollow plastic barrel having a top, a bottom, a predetermined height and circumference, and at least one flat outer surface formed in at least the bottom of the barrel, the bottom of the barrel forming an opening and having a radially inwardly extending lip about the circumference of the barrel, the bottom further forming an expanded diameter ledge; anda toroidal, detachable, low profile, self-ballasting, unitary molded base having a vertical opening therethrough, the base having dimensions and being adapted to receive the barrel through the opening and make a tight fit thereto, the base including:an upper portion that forms a tapered outer radial surface and an inner radial surface having a predetermined molded shape with a radially inwardly directed tapered lip to engage with the ledge and at least one flat interior surface to fit snugly around substantially the entire circumference of the bottom of the barrel and thereby create a tight fit between the barrel and base when the base is dropped down unto the barrel; anda ground engaging radially outwardly extending lower portion having a relatively larger cross-sectional area compared to the upper portion and to the cross-sectional area of the barrel, the lower portion having an inner radial ground engaging ring and an outer radial ground engaging ring and forming a series of recessed cusps circumferentially distributed about the base between the inner ring and the outer ring to reduce the weight of the base and to provide perimeter weighting to the base;whereby the relatively larger cross-sectional area of the lower portion extends significantly circumferentially outwardly beyond the upper portion and the barrel around the entire circumference of the barrel when the base is placed unto the barrel.
