Shallow mounted fixed vehicle barrier device

Abstract

A shallow mounted fixed vehicle barrier device for prohibiting vehicular access to a facility or area. The shallow mounted fixed vehicle barrier device includes a barrier system having a passive position and a support system adapted to maintain the barrier system in the passive position. In the passive position, the barrier system prevents vehicles from passing by or through to the protected facility or area. The shallow mounted fixed vehicle barrier device always remains in the passive position and, therefore, never allows vehicles access to the secured facility or area, after installation. The barrier system includes a bollard and, optionally, a bollard sleeve. The support system includes a base frame attached to the bollard, such that the base frame is adapted to secure the bollard during vehicular attack. The shallow mounted fixed vehicle barrier device can be installed in a foundation having a depth of less than twelve inches.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority of U.S. Provisional Patent Application No. 60 / 728,154, filed 18 Oct. 2005, the entire contents of which is hereby incorporated by reference.TECHNICAL FIELD [0002] The present invention relates generally to a fixed vehicle barrier device, and in particular to a fixed vehicle barrier device known as a bollard, which can be mounted in a less than twelve inch foundation. BACKGROUND OF THE INVENTION [0003] In recent years there has been a dramatic increase in the incidence of attacks on facilities and buildings by terrorists, other aggressors such as extremists, and even disgruntled employees throughout the world. Many of these attacks are directed against government facilities or other high profile locations. One of the most effective means of facility destruction is through the use of a vehicle carrying explosives. To successfully guard against such attacks a standoff distance must be created around the faci...

AI Technical Summary

Benefits of technology

[0010] The barrier system can include a bollard and, optionally, a bollard sleeve. The bollard generally stands a significant height above, and substantially perpendicular to, a foundation, thereby preventing vehicular access. The bollard is in communication with the support system, which is typically anchored within the foundation. The bollard sleeve can be a decorative sleeve that substantially surrounds the bollard, such that the bollard sleeve allows the bollard to be decoratively customized to match the architectural setting of the area or facility.

[0013] For added support and a stronger foundation, the base frame can include a plurality of studs that extend from each side of the base frame. The plurality of studs is adapted to bond with the concrete or other substance poured into the foundation during installation of the shallow mounted fixed vehicle barrier device. Further, the shallow mounted fixed vehicle barrier device can utilize rebar rods and rebar mats to assist in securing the shallow mounted fixed vehicle barrier device to the foundation. The rebar rods and rebar mats are of a particular size and installed in particular positions, in order to maximize the strength of the foundation.

[0014] The use of the base frame and rebar rods and mats allows the shallow mounted fixed vehicle barrier device to be adequately installed in a foundation having a depth of less than twelve inches. Accordingly, installation of the shallow mounted fixed vehicle barrier device does not intrude on infrastructure buried further below. Moreover, the shallow mounted fixed vehicle barrier device can be installed in many locations where traditional bollards could not be installed.

[0017] Still another object of the present invention is to provide a shallow mounted fixed vehicle barrier device having an aesthetically pleasing barrier design that can combine finishes and colors to match the architectural design of the facility being secured, thereby giving the engineers and architects, who design buildings with vehicular intrusion solutions, the ability to maintain the artistic design of the facility.

[0019] Yet another object of the present invention is to provide a shallow mounted fixed vehicle barrier device that adequately bonds with the concrete or other substance poured within the foundation, thereby adequately securing the bollard during a vehicular attack.

[0020] Another object of the present invention is to provide a shallow mounted fixed vehicle barrier device that eliminates the need for extensive site surveying and detailed engineering to allow a large number of bollards to be installed together.

Problems solved by technology

More specifically, the shallow mounted fixed vehicle barrier device always remains in the passive position and, therefore, never allows vehicles access to the secured facility or area.
