A vehicle barrier apparatus and corresponding methods include a base and a vehicle receiving member coupled to the base and having proximal and distal ends. Also included is a deployable element rotatably coupled to the base and coupled to the vehicle receiving member at a mechanical coupler located closer to the distal end than to the proximal end. The deployable element is configured to receive a transfer force, from the vehicle receiving member, via the mechanical coupler, responsive to the vehicle receiving member receiving an applied force from a vehicle at the proximal end. The deployable element configured to deploy from a stored orientation to a deployed orientation responsive to the transfer force. Accordingly, vehicle force can be transferred and used to deploy the device effectively in a self-triggered configuration without hazards of stored energy.

Barriers, such as vehicle impact barriers for placing upon an existing surface such as a road surface, or a paved surface, or a pedestrian surface. Surface-mountable and removable barriers are described for use as vehicle impact barriers. Such barriers may be employed for rapid deployment in a street, causeway or other route.

A traffic control device, for a roadway receiving vehicles travelling longitudinally along the roadway, includes a housing, which may be formed in two or more modular sections, mounted transversely across the roadway. A frame comprised of a shaft supporting tire puncturing members thereon is rotatable within the housing between stored and working positions for selectively puncturing tires. In modular embodiments, the shaft of each module includes a joiner plate supported at one end of the shaft to enable rigid connection between the shafts of adjacent modules. In some embodiments, offset counterweights are coupled to the frame to bias the tire puncture members towards the working position, and an upper stop member on the housing, formed of resilient material, is engaged by the frame in the working position and is adjustable in height to control position of the tire puncturing members in the working position.

Embodiments are directed toward a spike strip. The spike strip preferably includes a housing, a plurality of spikes disposed in the housing, a door, and a mover. The door is preferably configured to transition between a closed configuration in which the spikes are covered and prevented from puncturing tires of vehicles driving over the spike strip and an open configuration in which the spikes are exposed and allowed to puncture a tire of a vehicle driving over the spike strip. The mover is preferably configured to transition the door from the closed configuration to the open configuration responsive to a signal provided to the spike strip from a remote location.

The tire spiker with an extendable handle may comprise a pair of spike portions pivotally connected by a spring loaded hinge adapted to hold the spike portions in a deployed U-Shaped configuration to be deployed in front of and behind a tire in a traffic stop. An extendable handle on the frame may have a release button adapted to release a latch holding the spike portions together in a carry configuration. The spring loaded hinge urges the spike portions in a spaced, parallel orientation for surrounding a tire in a deployed configuration. The tire spiker with extendable handle is moved to a position whereby the two spike portions are in front of and behind a tire. The spike portions have upward oriented spikes adapted to puncture the tire if the tire rolls forward or backwards.

A wedge barrier system includes a frame to be disposed within a foundation, for example a shallow foundation, a wedge barrier comprising fingers having an asset end pivotally connected to the frame at an asset side and a blocking member extending perpendicular to the fingers and connected at threat ends of each of the fingers and a drive mechanism located below the top side of the frame and connected to one of the fingers to move the wedge barrier between a non-deployed position with the wedge barrier disposed inside the frame and a deployed position with the blocking member located above the top side.

In one embodiment, a deployable barrier container apparatus includes: in folded position, a container and, in unfolded position, a vertical barrier component is deployable on a base placed on the ground to oppose vehicle traffic approaching from an upstream side. A second side wall and a ceiling top are disposed on the downstream side of the base. A first side wall and a stowed top are disposed on the upstream side of the base and on which approaching vehicles move. The horizontal barrier component is disposed upstream of the stowed top and on which the approaching vehicles move, and the horizontal barrier component comprises an elongated sliding friction mat which creates a sliding friction interface with the ground upon contact of a moving vehicle with the deployed vertical barrier component in the deployed position. The base, side walls, and tops are rotatably connected to unfold to form the barrier apparatus.

The present subject matter provides a dissecting element that comprises a flat body having an upper side and a bottom side and opposite edges; a hinge on the bottom side wherein the hinge is connected to a surface, wherein the dissecting element is configured to move between an erected state in which the flat body is in an upright position and a horizontal state in which the flat body is adjacently lying on the surface. A plurality of dissecting elements can be provided on a portable ramp and several dissecting elements or ramps establish a barrier system. A method is also provided to prevent passage of vehicles using the dissecting elements.

A barricade includes a foundation frame, a finger wedge barrier, a hinge hingedly coupling the finger wedge barrier to the foundation frame, and an actuator mechanism coupled to the foundation frame and the finger wedge barrier. The finger wedge barrier is configured to rotate about the hinge between a stowed configuration and a deployed configuration, and the actuator mechanism is configured to rotate the finger wedge barrier between the stowed configuration and the deployed configuration. The actuator mechanism includes an actuator comprising a housing and a rod configured to reciprocally move in the housing, a first linkage having a first end rotatably coupled to the rod and a second end rotatably coupled to the finger wedge barrier, and a second linkage having a first end rotatably coupled to the rod and a second end rotatably coupled to the foundation frame.

A bollard system may include a bollard, a carrier device having a recess adapted to carry the bollard in a stowed configuration, and a pivot rod fixedly secured to the bollard and received by a pivot carrier of the carrier device. The bollard may be adapted to rotate about a longitudinal axis of the pivot rod between a deployed configuration and the stowed configuration. The bollard system may also include a lock plate adapted to be received by the carrier device to maintain the bollard in the deployed configuration. The bollard system may further include a cover plate carried by the carrier device and adapted to cover at least a portion of the recess of the carrier device in both the stowed configuration and the deployed configuration.
