The present invention relates to rapidly deployable traffic barriers (referred to as “expedient barriers”) which bring vehicles to a controlled stop by interfering with tire rolling.
This section introduces aspects that may help facilitate a better understanding of the invention. Accordingly, the statements of this section are to be read in this light and are not to be understood as admissions about what is prior art or what is not prior art.
Vehicle checkpoints, roadblocks, and barriers (i.e., “barriers” generally) manned by military personnel and/or law enforcement are becoming increasingly commonplace in the world we live in. There are several objectives of the barriers. To the greatest extent possible, the personnel who are operating the barriers must be protected from threats, typically associated with the vehicles and occupants the barriers are designed to stop. Of course, barriers usually serve to protect personnel and facilities within an established perimeter or region.
Often, in a crisis, expedient barriers must be rapidly deployed. As a result, vehicles containing peaceful civilians or other local police or military personnel may unexpectedly encounter an expedient barrier where none previously existed, be caught by surprise, and fail to appropriately slow down.
U.S. Pat. No. 10,024,008 discloses a vehicle barrier apparatus which includes a horizontal barrier component, a vertical barrier component, at least one rigid stabilizer beam having two end surfaces and at least one elongated side surface. One end of the stabilizer beam is affixed to the vertical barrier component. The elongated side surface of the stabilizer beam is affixed to the horizontal barrier component to prevent rotational movement of the vertical barrier component. A lower surface of the horizontal barrier component is a friction-enhanced surface which creates a sliding friction interface upon contact of a moving vehicle with the vertical barrier component. This patent is incorporated herein by reference in its entirety.
Hostile vehicle mitigation (HVM) continues to be of critical importance around the world, especially in urban environments. Many conventional solutions are too slow to deploy, require significant construction efforts, are not modular enough for limited duration requirements, or do not offer adequate protection against larger vehicle threats.
The present invention was developed to address the need for a robust, versatile, and adaptable approach to hostile vehicle mitigation. Research and development have led to a novel deployable expedient traffic entry regulator (DETER) based on packaging and integration of a pre-kitted wedge barrier into QuadCon size ISO container footprint. An active barrier wedge is integrated into a QuadCon base. The regulator can be used to regulate entry to an area or exit from the area. In this discussion, the traffic entry regulator is used to regulate entry of approaching traffic toward the traffic entry regulator from an entry side, with the traffic entry regulator as the point of reference. As such, it can be used to regulate entry into or exit from an area.
In one example, the QuadCon has a floor or base structure assembly, two top panels (a ceiling top panel and an extra, stowed top panel), and two side panels or side wall subassemblies which are connected via hinged connections. There are two removable end walls or panels or tarp covers, at least one of which may optionally be configured as one or two doors. In the QuadCon's closed or folded position prior to unfolding, the barrier is contained inside the QuadCon and disposed on its base structure assembly. To unfold the traffic entry regulator, the two end panels are removed and the two side walls and two top panels (ceiling top and stowed top) converted from the closed position to an open or unfolded position. In the open position, the traffic entry regulator is in a passive mode before the vertical entry barrier is erected and in an active mode after the vertical entry barrier is erected from the base, which is elevated above the ground. The two side walls and the top panels of the QuadCon are converted into ramps and toe ramps for the vertical entry/exit barrier and deployed on the ground. The side walls forming the ramps and the top panels forming the toe ramps have fiberglass grate decking on the interior sides that becomes the top sides of the ramps and toe ramps. For example, the grate decking is made of SPF polyester resin having 1.5″ height×0.6″ top flange width I-bar with medium grit surface and 60% open area.
On the entrance side of the vertical entry barrier is a sliding friction matting system. In specific embodiments, the ACEMAT sliding friction matting is provided in an accordion configuration that is unfolded and stretched out on the entrance/approach side upstream of the traffic entry regulator. In one example, the ACEMAT has three integrated continuous 4″ straps linking six 4′×8′ matting panels or mat sections folded in the accordion manner. The ACEMAT matting design is optimized based on ERDC's historical designs.
Each QuadCon is deployed to form a deployable expedient traffic entry regulator (DETER) unit. Multiple units can be joined in a modular manner using standard QuadCon corner castings to accommodate configurations of variable widths. For example, two traffic entry regulator units are deployed having a combined width of over 16′ to accommodate a representative Class 6 truck track width maximum standard spacing of 102″ per Federal size regulations for commercial motor vehicles. See https://ops.fhwa.dot.gov/freight/publications/size_regs_final_rpt/.
Deployment of the traffic entry regulator requires limited tools and equipment and no anchoring. The traffic entry regulator is of modular assembly. It is recoverable and reusable.
The result is an expedient, kitted non-anchored active vehicle barrier solution that is deployable in minutes with modular connectivity between units and is applicable for use in urban environments and provides hostile vehicle mitigation (HVM) capability against box trucks and other larger class vehicles. The traffic entry regulator possesses HVM capability focused on, but not limited to, operations in the urban environment, offering enhanced protection combined with the agility of a rapidly deployable system.

The container is typically an intermodal container, also known as a cargo or freight container, ISO container, shipping, sea or ocean container. One example of a suitable container 100 is a QuadCon. A QuadCon is a unique and versatile mini-container originally developed for use by the United States Armed Forces. The unit is configured to enable four containers to be secured together using the exclusive SeaLock connector. The resulting package has the same footprint as a standard 20′ ISO intermodal container. Each QuadCon unit has a base that allows four-way forklift entry.
The traffic entry regulator unit 100 is a rectangular container in the folded position. The container includes a floor or base structure assembly 104, two top panels (one ceiling top panel 106 and one stowed top panel 108), two side walls 112, and two end panels 116. The base structure assembly 104 is rotatably connected on one side with one side wall 112 and the ceiling top panel 106 and on the other side with the other side wall 112, the stowed top panel 108, and a horizontal barrier component 120. These structural components are typically made of weathering steel or Corten steel. In a specific embodiment, the base assembly 104 and stowed top panels 108 are each about 8′×4.75′ in size, and the side walls 112 are each 8′×8′ in size.
In specific embodiments, the end panels 116 at the two ends are light-weight panels or membranes that can be easily removed and be stored or set aside during deployment. At the base are four base corner members 130 at four corners of the base structure assembly 104. At the top are a pair of top corner crossbars 140 connecting and securing opposite top corners of the two side walls 112. Each top corner crossbar 140 incorporates two corner blocks 142 (e.g., ISO 1161 corner blocks) that function to retain the ceiling top panel 106 and the stowed top panel 108 in the folded position. Using ISO corner blocks meets the ISO container standard envelope by providing corner connectors at each box corner at specified locations. The side walls 112, ceiling top panel 106, and stowed top panel 108 have grate decking units 150 attached to the interior surfaces thereof.
The two side walls 112 include an entry (first) side wall 112A and an exit (second) side wall 112B. In the unfolded position, the entry side wall 112A is an entry ramp disposed on the entry side and the exit side wall 112B is an exit ramp disposed on the exit side of the traffic entry regulator unit 100. The (first distal top edge of the) entry (first) side wall 112A is rotatably connected to (the proximal stowed top edge of) the stowed top panel 108, which is an entry toe ramp in the unfolded position. The (second distal top edge of the) exit (second) side wall 112B is rotatably connected to (the proximal ceiling top edge of) the ceiling top panel 106, which is an exit toe ramp in the unfolded position. As such, the ceiling top 106 and stowed top 108 each have a tapered thickness that tapers from a thicker proximal ceiling/stowed top edge to a thinner distal ceiling/stowed top edge to provide the toe ramps in the unfolded position. Detail B of the rotational or hinged connection between the exit side wall 112B and the ceiling top panel 106 is illustrated in
The distal exit toe ramp hinge body subassembly 810 is attached (e.g., welded) to an end of the ceiling top panel 106 to form a hinge joint via hinge linkage members with the distal exit toe ramp hinge subassembly 820 to allow and control rotation of the ceiling top panel 106 from the folded position to the unfolded position to form an exit toe ramp on the ground. This hinged connection is created using a four bar linkage concept to allow the ceiling top panel 106 to rotate from a bottomed out position at perpendicular to the top of the exit side wall 112B, up and around the top of the exit side wall 112B, into the deployed position as the exit toe ramp on the ground. The exit top skin plate 830 is typically a steel plate that forms a cover over the exit toe ramp hinge linkage mechanism. The cover is on top in the folded position of the container.
Each proximal exit toe ramp hinge body subassembly 820 includes three pairs of proximal exit ramp hinge tabs that are attached (e.g., welded) to the top of the exit side wall 112B at three locations distributed along the length as shown (the middle pair being offset from the end pairs which are aligned) and combined with a standard ½″ diameter proximal bolt or bar 840, forming “fixed” proximal end pivot points for the three individual hinge linkage members.
In the unfolded position, the entry side wall 112A is strong enough to carry the heavy load of a vehicle such as a large truck weighing up to about 30,000 pounds. In the embodiment shown in
The exit side wall 112B may have the same structural components as the entry side wall 112A. The ceiling top panel 106 and stowed top panel 108 have similar grate decking units 150 attached to the interior surfaces thereof. To support heavy vehicles, the entry and exit side wall 112A, 112B each typically weigh about 1500 pounds. During unfolding of the container, these heavy side walls can be lowered to the ground and raised using an integrated winch provided in the container. Alternatively, an external lift mechanism can be utilized to handle and manipulate the heavy side walls.
In specific embodiments, the horizontal barrier component 120 is similar to that disclosed in U.S. Pat. No. 10,024,008, which is a mesh made solely from a plurality of interconnected link components as disclosed in
In specific embodiments, the three 4″ straps 1310 running lengthwise connecting all 6 matting panels 1300 are each fabricated with about 18 feet of strap hanging out the end of the ACEMAT assembly 120 that interfaces with the rest of the barrier. These strap “tails” will be fed through voids provided in the toe ramp 108, through a void in the entry side wall 112A and attach to hardpoint connections within the base assembly 104 (e.g., below the floor surface on top of the base assembly) of the barrier. In this way, the ACEMAT assembly 120 will be “pre-connected” when a traffic entry regulator unit 100 is unfolded. There may also be 2×4″ strapping running in the transverse direction with excess hanging out of the 4′×8′ fiberglass panel area such that connection can be made (e.g., using mechanical buckles) the ACEMAT assemblies of multiple joined traffic entry regulator units to provide multiple widths.
To move from the passive barrier position to the active barrier position, the slide bars 2120 are pulled upward away from the base 104, which causes the pivoting bars 2110 to pivot upward from the base 104 around the first pivot line 2210 and the pivoting supports 2130 to pivot upward from the base 104 around the second pivot line 2220, as the slide bars 2120 slide along the pivoting bars 2110 approximately ¼ to ½ of the way along the length of the pivoting bars 2110 to a locked position. Any suitable locking mechanism may be used to lock the slide brackets 2140 in the locked position. For reference, the slide brackets 2140 travel “over center” and hold themselves locked until the slide bar 2120 is picked back upward along the length of the pivoting bars 2110. For example, locking tabs 2250 may be provided on the pivot bars 2110 to engage the slide brackets 2140 in the locked position. The locking tabs 2250 may be spring-loaded. The slide bars 2120 form, via the rotational connection at the slide brackets 2140, a third pivot line 2230 disposed horizontally, transversely, and slidably along the pivoting bars 2110. The pivoting bars 2110, pivoting supports 2120, and slide bars 2130 form the active wedge barrier in the active barrier position. To move the vertical barrier component 2100 back to the passive barrier position, the locking mechanism is unlocked and the pivoting bars 2110, slide bars 2120, and pivoting supports 2130 are pushed back into the base 104 by pivoting relative to the first pivot line 2210, second pivot line 2220, and third pivot line 2230.
A more detailed description of operating the connection tools 2300 is provided here. The first traffic entry regulator unit 100 is folded out. Two connection tools 2300 are placed into the entry and exit corner ISO blocks 610 of the entry and exit corner members 130, respectively, with the handles 2320 in vertical position. A second traffic entry regulator unit 100 (still in folded form) is aligned and pushed to a location where its neighboring entry and exit corner ISO blocks 610 of the entry and exit corner members 130 are engaged by the in-place connection tools 2300 and then the second traffic entry regulator unit 100 is moved toward the first unit 100 until all available clearance is removed. Each connection tool 2300 has both elliptical disks on opposite sides engaged into two adjacent corner blocks 610 via the elliptical or elongated side openings 650 on the two adjacent traffic entry regulator units 100. The two connection tools 2300 are rotated downward and outward relative to the base 104 and allowed to rest on the ground. The connection tool handle 2320 is rotated 90 degrees into the horizontal position as a locking mechanism to prevent the tool from rotating off of the ground and allowing units to disengage from each other, by virtue of the elliptical or elongated connection disks 2310 and the elliptical or elongated side openings 650. The second traffic entry regulator is then unfolded. The horizontal positions of the handles 2320 underneath deployed walls/ramps prevent the tools 2300 from being disengaged due to vehicle impact (
