Benefits of technology

[0013]Still another general object of this invention is to provide a reasonably portable security barrier system that is relatively easily assembled, disassembled, and transported to a different site.
[0072]all of steps (a) through (k) being performed with little or no damage to the component parts of the assembly such that those component parts can be reused.

Problems solved by technology

Such expanded metal fencing can be formed with screen-like openings that are large enough to afford visibility but not large enough to provide handholds or toeholds in order to resist climbing without the use of special equipment.

Embodiment Construction

[0084]A redeployable barrier fence system 10 in accordance with this invention, as schematically illustrated in FIG. 1, comprises two integrated and cooperating portions: (1) a vehicle-impact resistant foundation or lower structure 12; and (2) a scaling-resistant, substantially visually-transparent upper fencing portion 14, preferably comprising expanded metal mesh 16 secured to a post-and-rail support system 18 comprising post members 24 and rail members 26. The foundation structures of this system serve as the vehicle crash barrier as well as providing a foundation for and a means of securing the post members of the post-and-rail system. The foundation structures also afford tunneling resistance. The expanded metal mesh upper fence portion of this system provides personnel penetration resistance as well as affording good visibility between the protected side of the security barrier and the attack side.

Abstract

A redeployable security barrier system and methods for using the same are disclosed, the barrier system comprising an assembly of individual foundation barrier units or structures, which provide a vehicle-impact resistant foundation portion, and an upper, generally visually transparent, personnel-scaling resistant fence portion that spans the assembly of barrier units.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a combination vehicle barrier / fencing system useful in border security and facility security applications.BACKGROUND OF THE INVENTION[0002]In recent years there has been a growing need to secure national land borders and various sensitive facilities, at least temporarily, from unauthorized human access and entry, especially by means of motor vehicles. There has been growing concern about securing national borders against illegal immigration, such as along the southern border of the United States, especially with the increased risk that some individuals attempting to illegally enter the country could be criminals or terrorists. Such a border security system would typically be permanent or at least semi-permanent.[0003]In addition, because of the threat of domestic terrorism, it may periodically become necessary to temporarily secure certain facilities against unauthorized entry by individuals on foot or driving mo...
