High Impact Gate

Abstract

This invention relates to a security gate. It is particularly related to a high impact gate able to withstand significant direct impact of vehicles and maintain a secure location by prevention of access by vehicle or foot. There is provided a high impact gate system including a lower reinforced elongated structure and an upper barrier means sized to extend across a roadway, and two spaced reinforcing means able to be positioned to at least partially overlap respective end portions of the elongated structure when the lower structure is in a closed position extending across the roadway, the reinforcing means able to provide supporting reinforcement to the elongated structure when receiving impact by vehicle or the like.

Description

[0001]This invention relates to a security gate. It is particularly related to a high impact gate able to withstand significant direct impact of vehicles and maintain a secure location by prevention of access by vehicle or foot.[0002]Barriers of all types are used throughout the world to prevent intrusion into restricted areas or retain personnel or goods within restricted areas. Intruders include unwanted personnel, animals, and vehicles. At times personnel and goods must enter or leave restricted areas, resulting in the requirement for at least part of the barrier to be movable. Movable barriers, such as gates, doors, and movable portions of walls, allow passage out of and into restricted areas. However they greatly reduce the barrier effect and usually rely on being merely a demarcation line requiring security personnel to patrol and form the effective control barrier. Such an approach is not sufficient in these times.[0003]In granted U.S. Pat. No. 4,828,424 there is shown a vehi...

Benefits of technology

[0013]Also there is provided a high impact gate including a lower structure and an upper section mounted on the lower structure, the lower structure sized to take the impact of a vehicle and the upper section providing a vertical barrier, the lower structure formed by a boxed structure having two spaced linear structures joined by cross diagonal bracing to form a high impact barrier. The spaced linear structures having “I” beams and extending substantially horizontally with the diagonal bracing being in a vertical cross section. The lower structure can include a first end part mounted on a sliding mechanism and allowing the distal second end to be cantilevered such that the second end can extend at least partially over a roadway to prevent unauthorized entry and the sliding mechanism allows sliding out of the way for author

Problems solved by technology

Intruders include unwanted personnel, animals, and vehicles.

However they greatly reduce the barrier effect and usually rely on being merely a demarcation line requiring security personnel to patrol and form the effective control barrier.

Such an approach is not sufficient in these times.

However this patent only discloses the need for a collapsible structure in order to perform the impact security system.

The system does not allow ready opening in combination with high security.
