Patent ID: 8167512

Claim:
A barrier assembly comprising: a barrier having an interior surface and an opposing exterior surface extending between a first end and an opposing second end, the interior surface bounding a chamber that is adapted to receive a ballast, the barrier comprising: a central body portion extending between a first end face and an opposing second end face, the central body portion including a floor extending along the length thereof; a first projection portion outwardly projecting from the first end face of the central body portion, the first projection portion having a top surface, an opposing bottom surface, and an internal sidewall extending between the top and bottom surfaces so as to bound a first passage extending completely through the first projection; and a second projection portion outwardly projecting from the second end face of the central body portion, the second projection portion having a top surface and an opposing bottom surface with an opening being formed on the top surface, a receiver being disposed within the opening, the top surface of the second projection portion having an elevational location lower than the top surface of the first projection portion when the floor of the central body portion is horizontally disposed on a ground surface, an elongated coupler extending down through the first passage and projecting below the bottom surface of the first projection, the elongated coupler comprising: an elongated shaft being rotatably disposed within the first passage and having a first end and an opposing second end; an enlarged head disposed at the first end of the shaft; and a connector disposed at and radially outwardly projecting from the second end of the shaft, the connector being sized so that the connector cannot freely pass through the first passage, the connector being configured so that for identical barriers where the first projection of one barrier overlies the second projection of the other barrier, the connector can securely engage with the receiver within the opening of the second projection for securing the barriers together.
