Abstract:
A security barrier apparatus that includes a ground sleeve that is concreted into the ground at finish grade height and a uniquely configured jam member that is movable within the ground sleeve from a first free position to a second jammed position in engagement with the inner wall of the tubular sleeve. Connected to the jam member and extending upwardly therefrom is an elongated tension bar having an upper, internally threaded portion that is receivable within the hollow body portion of the apparatus. The jam member includes a tapered wall portion that is mateable with a tapered wall portion provided on the lower portion of the apparatus. A draw bolt extends through the cover of the ground sleeve and is adapted to threadably engage the upper threaded portion of the tension bar. Rotation of the draw bolt will cause the jam member to move upwardly within the ground sleeve in a manner to cause the tapered surface of the jam member to move into jamming engagement with the tapered surface of the ground sleeve securely locking the apparatus in place.
