ABSTRACT:
An inertial barrier system is provided which is comprised of inertial barriers formed of two modules, each of them being differently sized and being adapted to stack one upon the other. An interlocking geometry on each of the mating ends of modules assists in obtaining a secure stacking arrangement, and also assists in varying the volumetric capacity of each of the two modules. Thus, when the smaller of the two modules is the upper module, facing upwardly so that its volumetric capacity is available for filling by a particulate ballasting material, a lighter weight barrier is obtained. On the other hand, when the two modules are inverted, and the larger one is the upper module, its greater volumetric capacity ensures that, once filled by the ballasting material, a heavier barrier will result. Advantageously, each module is sized to ensure a barrier of the proper weight when it is placed in the position of the upper module and is properly filled by a worker. Because of the differing appearance of the barriers, depending upon which module is disposed as the upper module, another advantageous feature of the invention is that it is easy to determine by visual inspection of a particular barrier what should be its approximate correct weight.
