Spiked Barrier

Abstract

A low-harm spiked barrier for a structure such as a fence is disclosed which has a base having spikes. The spikes are spaced apart by a distance less than that required to obtain a finger grip or a foothold on the base between the spikes. The spikes are slightly rounded so the spikes will not likely cause permanent injury and the spikes also provide a psychological deterrent if someone attempting to scale the structure on which the spiked barrier is mounted.

Description

RELATED APPLICATION [0001] This application claims benefit of Australian provisional application no. 2006902483 filed on 11 May 2006 and entitled “SPIKED BARRIER”. The Australian provisional application is incorporated herein by reference. FIELD OF THE INVENTION [0002] This invention relates to a low-harm spiked barrier for mounting on a structure such as a fence, wall or other barrier to deter human intruders and also to prevent animals from walking on the structure or climbing over the structure. BACKGROUND OF THE INVENTION [0003] The use of deterrent security elements on barriers is known and can comprise coiled barb wire, straight lengths of barb wire, embedded glass or other sharp objects and pointed spikes. In general, such elements are designed to prevent humans from scaling and crossing a barrier by causing injury to the person should the person attempt to scale the barrier. In most instances, these types of barrier elements are successful in preventing people from scaling t...

AI Technical Summary

Benefits of technology

[0007] The object of a first aspect of the invention is to provide a low-harm barrier which provides a deterrent to people scaling a structure and also animals from walking along the top of the structure or scaling and crossing the structure without any significant degree of likely injury to the person or animal.

Problems solved by technology

Because of the disposition and spacing of the spikes, a person is unlikely to be able to obtain a good grip on the top of the structure to facilitate scaling and crossing the structure and therefore is deterred from any attempt to scale the structure.

Since the deterrent is due to preventing a good grip which would facilitate scaling of the structure, the deterrent is such that it is unlikely to cause any significant injury to a person.

Furthermore, because the spikes are so spaced, animals are equally unlikely to be able to obtain a good footing between the spikes, thereby preventing an animal from scaling and crossing the structure or walking along the top of the structure, again without causing injury to the animal.
