Claim:
A security barrier apparatus comprising: a first elongate structural member for preventing ingress into a protected area, wherein the first elongate structural member is disposed in a substantially horizontal plane when in a closed position and wherein a second end of the first elongate structural member includes two substantially vertically extending members extending away from the first elongate structural member in opposite directions; an upright member, at least a portion of said upright member is on a protected side of the elongate structural member; and at least one passive engagement device for snaring the first elongate structural member, the passive engagement device comprising two horns extending substantially horizontally from the upright member in a direction substantially orthogonal to a length axis of the first elongate structural member when the first elongate structural member is pivoted into the closed position, wherein the horns are adjacent the second end of the first elongate structural member when the first elongate structural member is pivoted into the closed position such that, when the first elongate structural member is impacted in a direction toward the protected area when the first elongate structural member is in the closed position, the first elongate structural member contacts the portion of the upright member on the protected side of the elongate structural member and the horns snares the substantially vertically extending members.
