Abstract
A barrier system includes discrete movable barriers molded from a resiliently deformable plastic. Each of the barriers includes a housing having opposing front and back walls and opposing triangular shaped sidewalls. The front and back walls extend from a floor and intersect at a rounded top portion. Each barrier includes an interior surface that defines an internal chamber. The internal chamber can be selective filled with a ballast through an opening. Recessed within the front wall and back wall are a plurality of pockets. The pockets form reinforcing ribs which substantially prevent the deflection of front and back wall when the internal chamber is filled with ballast. In contrast, the sidewalls are substantially smooth to enhance bowing thereat when the internal chamber is filled with ballast. Recessed within the floor of each barrier adjacent to each of the sidewalls is a slot. Upstanding legs from an U-shaped connector are received within corresponding slots when sidewalls of adjacent barriers are biased together. The connector thus secures the barriers together. A tenon and mortise is formed on the front wall of each of the barriers and are configured such that front walls o…
