  • a barrier system generally designated 100 in accordance with an exemplary embodiment of the present invention.
  • the barrier system 100 may be configured to stop or hinder someone from driving a vehicle into an area.
  • the barrier system 100 may protect a structure within the area (e.g ., building), an area itself (e.g., outside dining tables), and/or an area occupied by pedestrians (e.g., a sidewalk).
  • the barrier system 100 may be useful to prevent egress of cars from a storefront where there is heavy foot traffic and otherwise unobstructed access to glass doors and windows.
  • a series of barrier systems 100 may be used to create a vehicle barrier but allow for pedestrian traffic between the barrier systems 100.
  • the barrier system 100 may include or also be referred to as a bollard.
  • Existing bollards may pull out of the ground partially or entirely, break, or shear off entirely upon impact with a vehicle allowing egress of the vehicle into the area intended to be vehicle free and/or causing the bollard or portions of the bollard to become a dangerous projectile. Because existing bollards are typically rigid structures, an impact with the bollard may also or alternatively result in unnecessary injury (e.g., avoidable air bag deployment) and/or damage to a vehicle. Damage to the vehicle and air bag deployment may be of particular concern in minor incidental impacts between a vehicle and a bollard (e.g., where a driver drives forward rather than in reverse when pulling out of a parking space in front of a building).
  • bollards are typically hollow metal pipes filled with concrete. While such a bollard may give the impression of a secure barrier, such bollards have drawbacks. For one, concrete has low shear strength especially since the metal pipe is susceptible to corrosion. Also, typical barriers are often supported by too shallow or too massive of a footing resulting in the bollard ripping out of the ground upon impact or a reluctance by the property owner to replace the bollard after minor impacts with a vehicle due to the amount of concrete that would need to be replaced and the heavy machinery involved. Further, the underground footing reinforcement, if any, is typically manufactured on site and subject to assembly errors and oversights that are undetectable once installed and the underground portion is encased in concrete.
  • the barrier system 100 described herein is more resistant to corrosion and may undergo limited deflection when struck by an object to deflect and absorb some of the impact energy.
  • the barrier system 100 may also have further impact absorbing features such as covers and dampers and be easier to install and replace than traditional safety barrier systems as discussed in further detail below.
  • the barrier system 100 may also have a pre-fabricated footing assembly that reliably retains the barrier system 100 in the ground while being easier to install and taking up a smaller footprint than traditional barrier systems.
  • the barrier system 100 includes a post 120.
  • the post 120 may bend or deflect when impacted by a vehicle to deflect and absorb some of impact energy when struck by a vehicle as discussed in further detail below.
  • the post 120 may be or may include a core 124.
  • the core 124 is a solid core (e.g., a core having a solid cross section). Existing hollow bollards may buckle when impacted by a vehicle.
  • a core 124 having a solid cross section may resist buckling.
  • a core 124 having a solid cross section may be resilient or bendable.
  • the core 124 may be solid across at least a majority of its cross section such that there are no holes or gaps.
  • the core 124 may be cut from a stainless steel rod stock.
  • at least a portion of the core 124 is hollow (e.g., such as proximate the proximal end for attachment to the footing and/or proximate the distal end to
  • the core 124 has a substantially solid cross section (e.g., any central axially extending hole has a diameter that is less than about 50%, about 25%, or about 10% of the core diameter).
  • the core 124 may be comprised of 4-inch diameter hot dipped galvanized steel rod stock that is cut to the desired length.
  • the desired length is about 60 inches. In some embodiment, the desired length is at least 60 inches. In other embodiments, the desired length may be about 90 inches, about 85 inches, about 80 inches, about 75 inches, about 70 inches, about 65 inches, about 60 inches, about 55 inches, about 50 inches, about 45 inches, or about 40 inches.
  • the rod stock is turned on a lathe to remove an outer layer of the core 124 (e.g., an outer layer having a thickness of about 1 millimeter).
  • Removing an outer layer of the core may help with galvanizing the steel, to make the core 124 the desired diameter, and/or improve the appearance of the core 124, particularly for cores 124 that will be visible after installation.
  • the core 124 is galvanized after it is turned on the lathe. In other embodiments, the core 124 is galvanized after the core 124 is cut from rod stock.
  • the core 124 may be resilient such that the core 124 flexes to absorb some of the force of impact from a vehicle.
  • the core 124 may be comprised of metal such as stainless steel (e.g, 316L stainless steel), 1045 hot rolled steel, 1045 polished steel, 1018 hot rolled steel, A36 steel, 12L14 steel, 1117 hot rolled steel, 1141 hot rolled steel, 1144 steel, or 4140 steel).
  • the core 124 may be galvanized. By providing a solid core without concrete that extends from a secure base in the ground, the barrier system 100 is more corrosion resistant and configured to elastically bend or deflect when impacted by a vehicle, as described in greater detail below.

  • the cover 122 may reversibly bend radially inwardly toward the core to absorb minor impacts with the barrier system (e.g., a vehicle weighing up to 5,000 pounds traveling under 5 miles per hour).
  • the post 120 may include the cover 122 and the core 124.
  • a center of the cross section of the post 120 may be solid.
