Patent ID: 8439594

Claim:
A flush-mounted vehicle control barrier, comprising: a sub-frame defining a bottom barrier surface, a top barrier surface, and an interior space between the bottom barrier surface and the top barrier surface; a wedge plate coupled at a rear edge to the sub-frame via a hinge mechanism and coplanar with the top barrier surface when configured in a stowed position; an actuator mechanism coupled to the wedge plate and disposed within the interior space when the wedge plate is configured in the stowed position, the actuator mechanism operative to rotate the wedge plate between the stowed position and a deployed position; and a control linkage coupling the actuator mechanism to the wedge plate, the control linkage comprising an upper control linkage member, a lower control linkage member, and a central control linkage member rotatably joined at a central joint and configured to translate a linear horizontal motion of the actuator mechanism to an upward deploying force operative to rotate the wedge plate upward around the hinge mechanism.
