ABSTRACT:
A bollard having a plurality of parallel, vertical legs spaced apart from each other on the perimeter of a regular geometric shape. The minimum number and/or cross-section of the legs is governed by the need to avoid creating an entrapment area between adjacent legs. If an even number of legs is provided, they can be arranged in diametrically opposite pairs of decreasing height, the pairs of legs being joined at their tops to form a series of at least three nested, inverted substantially U-shaped forms of decreasing height set around a common vertical axis. The bollard also includes elements for joining the legs together as a unit, for example, a cylindrical center member having the common vertical axis of the legs as its longitudinal axis, a longitudinal rib joining each leg to the center member, and a plurality of horizontal ribs joining adjacent legs to each other.
