AI Technical Summary

Benefits of technology

Significantly increases the time required to cut through the bollard, providing sufficient time for authorities to intervene and prevent unauthorized access.

Problems solved by technology

Whilst the use of such tools may be noisy and still take an operator several minutes to cut through a bollard, it is often shorter then the response time of the police or security services allowing enough time for persons to gain access to an area.

Embodiment Construction

[0038]The following detailed description of the invention refers to the accompanying drawings. Although the description includes exemplary embodiments, other embodiments are possible, and changes may be made to the embodiments described without departing from the spirit and scope of the invention. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.

[0039]Turning now to the drawings in detail there is shown in FIG. 1 a bollard 10 embedded below ground level 12 into a cavity 14. The bollard 10 includes a metal shell or tube 15 with central core 16 extending from the bottom of the bollard towards the top where it abuts plate 18, the bollard then having a cap 20. Steel tubes 22 extend from below ground level 12 to plate 18 and each houses a jamming bar 24. Spring 26 is housed below the tube and the jamming bar and exerts upward pressure on both. Typical loading of pressure may be up to 80 kg...

Abstract

The present invention relates to a a security bollard and, in particular, to a security bollard designed to be used as a protective measure to be placed in front of shop fronts and Automatic Teller Machines (ATMs) that may be subjected to ramming by vehicles. The bollard includes a first upright hollow member having an outer wall defining a chamber, and a plurality of vertical longitudinal jamming rods disposed inside the chamber. Each jamming rod has associated therewith a biasing means for biasing the members in a longitudinal direction so as to act like a disk brake on cutting implements attempting to cut through the jamming rods, and to also dose the gap created by the cut should the cutting implement be retrieved and cutting attempted again.
