Abstract
An inertial barrier system comprises 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. One of the two modules functions as a container, facing upwardly so that its volumetric capacity is available for filling by a particulate ballasting material. The lower module functions only as a pedestal for the support of the upper module. The upper module is advantageously fillable to different predetermined levels, so that the apparatus, comprising the joined lower and upper modules, is capable of functioning as differently weighted barrier systems.
Claims10
An inertial barrier for protecting a vehicle from a roadway hazard, comprising:
- a container having an outer sidewall and an interior volume, and a mating end;
- and
- a pedestal having an outer sidewall and a mating end, the pedestal being differently configured than the container and being adapted to mate with and support the container in a vertical stacking orientation to together form said inertial barrier, wherein more than half of the outer sidewall of said container extends above a highest portion of said pedestal and wherein a portion of the outer sidewall of the pedestal forms an inwardly tapered conic section, in order to provide increased strength in compression for the barrier in the vicinity of the respective mating ends of each of the pedestal and the container;
- wherein one of the pedestal and container mating ends includes a projecting portion, and the other of the pedestal and container mating ends includes a recess portion which is complementary to said projecting portion, so that when said container and said pedestal are joined together in said vertical stacking orientation, said projecting portion is engaged into said recess portion to form an interlocking relationship between the container and the pedestal.
An inertial barrier for protecting a vehicle from a roadway hazard, comprising:
- a container having an outer sidewall and an interior volume, and a mating end;
- and
- a pedestal having an outer sidewall and a mating end;
- the pedestal being disposed on a surface, with its mating end being an upper end thereof and the container being disposed on the mating end of said pedestal, the container mating end being a lower end of the container and being engaged with the pedestal mating end to together form said inertial barrier, wherein more than half of the outer sidewall of said container extends above a highest portion of said pedestal;
- said container being differently configured than said pedestal;
- wherein a portion of the outer sidewall of said pedestal forms an inwardly tapered conic section, relative to a remaining portion of the outer sidewall of the pedestal, in a region adjacent to the pedestal mating end, in order to provide increased strength in compression for the inertial barrier in a vicinity of the mating end of the pedestal.
