The invention encompasses a substantially animal-proof barrier that includes (a) two supports that are laterally spaced apart to define a substantially vertical plane there between; (b) fencing material that is attached to each of the supports and spans the defined substantially vertical plane to form a simple barrier that has a top edge, a bottom edge, a front surface and a back surface, wherein the simple barrier divides a domain into a first area and a second area; and (c) a hood having an inner surface, the hood originating from the top edge of the simple barrier. An angle formed by the inner surface of the hood and the front surface of the simple barrier measures about 10 degrees to about 80 degrees, such that a channel having a substantially V-shaped cross section is formed.

A fence panel comprising a rectangular sheet of mesh material with opposed first and second edges, and opposed third and fourth edges, the sheet being formed with a plurality of spaced apart and parallel channel-shaped reinforcing formations, and a plurality of deterrent components each of which includes an elongate strip of projecting spikes fixed to at least one side of the mesh sheet.

A security device comprising: a barrier, and a plate, wherein the barrier and the plate are releasably attachable to each other, and when the barrier and plate are attached the device comprises a slot for receiving a rail and the device may hang on a rail with the rail received in the slot, and the barrier protrudes in a horizontal direction, perpendicular from a plane extending downwardly from the rail, to provide an overhang; and wherein at least a portion of the plate is made from a bullet-resistant material.

A security fence structure including posts, rails, fence gratings, mounting brackets, fence clips and fasteners is easily assembled in the field. The rails are secured to the post by mounting brackets and fasteners, and the fence grating secured to the rails by means of the fence clips and fasteners. The fence gratings, in conjunction with the mounting brackets, fence clips and fasteners are resistant to climbing.

The present invention provides a substantially animal-proof barrier that includes (a) two or more supports laterally spaced apart to define a substantially vertical plane between each support, (b) fencing material that is attached to each of the supports and spans the plane between each support to form a simple barrier, wherein the simple barrier divides a domain into a first area and second area, (c) a hood having a first section originating from a top edge of the simple barrier that forms an angle of about 10 degrees to about 80 degrees with the simple barrier, and a second section extending from a lower end of the first section in a direction towards the simple barrier, and optionally (d) a hood corner assembly to provide a hood at a corner formed by the simple barrier, that includes an upper corner section, a lower corner section, and a pair of brackets.

A high security top element assembly for a security wall includes arcuate elements extending outwardly and downwardly from the top of a wall. The arcuate elements extend in both directions from the top of the wall. The arcuate elements terminate outwardly from the wall a sufficient distance to prevent a person climbing the wall from reaching out and contacting the arcuate elements and the arcuate elements are spaced apart a sufficient distance to prevent a person from passing between adjacent elements.

The invention addressed in this application is non-injurious restraint type form of fencing designed to be used a perimeter or security fence. The fence is constructed of hollow polymer tubes arranged in horizontal rows affixed to a vertical post. The hollow tubular horizontal fence rails contain fibers that are coated with a moisture cured adhesives and the fibers are secured at one end to the end cap of the tubes. The tubes are sealed and slightly pressurized with a dry inert gas, so that upon breakage of the tubes by a person attempting to scale the fence, the fibers are expelled out of the tubes and entangle the would be climber. The tubes are constructed of a brittle material, like polystyrene, or material which will become brittle upon treatment with ultra violet (UV) radiation or heat.

A method for inhibiting ingress of small animals into a utility installation and/or a municipal site includes the step of: surrounding the utility installation and/or municipal site with a fencing system. The fencing system includes: a plurality of anchored posts, a fencing material spans the posts and is affixed thereto, the fencing material has an upper edge portion, and an animal barrier extends along and is affixed to the upper edge portion, the animal barrier is semi-annular in vertical cross-section with an outward convex surface and an inward concave surface, the concave surface faces the fencing material. Whereby, when the small animal attempts ingress over the fencing system, the animal barrier inhibits that ingress to the utility installation and/or municipal site.

A security device comprising: a plate (20) having an upper portion (21) and a lower portion (22), wherein the upper portion and the lower portion are parallel and off-set; a bulbous barrier (30), wherein the upper portion of the plate and the barrier form a slot (50) therebetween, and the barrier extends in a direction perpendicular to the upper portion of the plane of the plate and away from the slot.
