US 12,146,279 B2 · Portable vehicle barrier

Abstract

A portable vehicle barrier is transportable to a desired location, unfolded from a compact transport configuration and deployed to provide an effective vehicle barrier that can be used temporarily and then refolded into the compact transport configuration and transported to a remote location for utilization or storage. The vehicle barrier is formed with a central base having front and rear sections that are pivotally hinged to the central base. A barrier member can be selectively activated to rise into an active position and restrain the passage of vehicles. An impact into the barrier member causes the central base to tip in order to drive pointed teeth into the tires of the vehicle and into the underlying road surface and stop the impacting vehicle. The front and rear sections have vertical bars that move into a nesting horizontal position when the front and rear sections are pivoted into the transport position.

Dependent claims

A portable vehicle barrier for deployment on a roadway surface, comprising:

a base member having a central section, a front section pivotally connected about a forward transverse pivot axis to said central section and a rear section pivotally connected to said central section by a rearward transverse pivot axis, said central section having a transverse row of forward pointed teeth along said forward transverse pivot axis and a transverse row of rearward pointed teeth along said rearward transverse pivot axis;
a resistance structure including a transverse beam and orthogonal mounting legs at the opposing transverse ends of the transverse beam, said mounting legs being supported on a transverse pivot for vertical movement of said beam between a lowered passive position and a raised active position;
and
an actuator mechanism operatively coupled to said beam to move said mounting legs about said transverse pivot to affect movement of said beam between said passive position and said active position, an impact between a vehicle and said transverse beam when in said active position causing an upward pivotal movement of said central section about said rearward transverse pivot axis to drive said forward pointed teeth into said vehicle.
