  • Patent number: 10278381
    Abstract: A mounting frame for bird spike strips is an apparatus that is used to support a set of bird spike strips upon a billboard, sign, stand, or other structure upon which various birds would otherwise rest. The apparatus includes a first mounting rail, a second mounting rail, a first support bracket, a second support bracket, a spike attachment mechanism, and an anchoring mechanism. The first mounting rail and the second mounting rail are utilized to provide a stable mounting surface for bird spike strips. The first support bracket and the second support bracket enable connection of the first mounting rail and the second mounting rail to a billboard, sign, stand, or other structure. The spike attachment mechanism ensures that the previous problem of the traditional adhesive on bird spike strips fading or providing insufficient connection to billboards, signs, stands, or other structures.

  • Publication number: 20090050862
    Abstract: The security fence spike is attached to the upper rail of a chain link security fence or the like, to project generally diametrically through a coil of razor wire or concertina wire strung along the upper rail of the fence. The security spike is a rigid metal projection, and resists collapse when a heavy sheet of material or blanket is tossed over the coiled wire atop the fence by a person(s) attempting to scale the fence. A row of spikes is preferably installed along the upper rail of the fence, threatening injury to anyone attempting to scale the fence even after covering a coil of razor wire or the like atop the fence. The security spike is formed of sheet metal bent to form a triangular cross section for rigidity and strength. The spike is attached to a brace band, which, in turn, is clamped to the fence.

  • Publication number: 20090032788
    Abstract: A large, hollow cylindrical top rail is installed along the top surface of a security fence. The rail has a lengthwise groove and fence post holes cut from the bottom of it. The hollow round rail is placed over the fence and fence posts and secured to the fence by removable fasteners. A spacer may also be inserted between the top of the fence post and the top of the rail to increase the height of the security rail. Lights, security cameras or motion detectors may be placed inside the hollow top rail. Once the top rail is in position, expandable foam is injected into the hollow area of the rail. The foam adheres to the fence and posts and the top rail is permanently attached to the fence. The fasteners may then be removed. The rail is slick, round and approximately a foot in diameter. This precludes anyone attempting to scale the fence from obtaining a handhold on the top of the fence.

  • Patent number: 5606830
    Abstract: An anti-bird perching device which can be installed by draping over railings, water pipes, wire cables or the like, either as a permanent or temporary barrier or deterrent for keeping both small and large birds from landing or perching on the understructure to be protected is described. The device comprises two identical panels made of a wire open rectangular grid fencing which said panels are hingedly attached to one another at spaced horizontal points, and wherein the wire material above the hinge points define two parallel rows of crisscrossing upwardly projecting wire prongs or spikes defining a surface which deters birds from landing or perching thereon. The hinged attachment permits the two-wire panel units to be pulled apart for installation or collapsed tightly together for compact shipping and storage applications. A method of installing multiple barrier units along a span of electric cable, telephone wire or water pipes and the like is also disclosed.

  • Patent number: 5461364
    Abstract: An intrusion detection device that can be used singly or in multiplicity to immediately and silently alert the user of attempts to climb over a security fencing system. The invention consists of a base element which attaches to the security fencing, and an alarming arm. The alarming arm is equipped with barrier material, such as concertina wire or barbed wire. The alarming arm is connected to the base element both at a pivot point and through a tensioning means. Attempts to climb over the barrier material result in additional loading of the alarming arm which rotates transversely about the pivot point, and against the force of the tensioning means. This rotational displacement of the alarming arm enables an electrical sensing device which then signals that an intrusion is in progress.

  • Patent number: 5433029
    Abstract: A bird repellent apparatus which is specifically designed for installation on telephone and electrical wires and the like or other extremely narrow, elongated surfaces to which it would be difficult, if not impossible to install any prior art bird repellent apparatus. More specifically, a channel member is configured for receiving a large plurality of top members in a continuous serial array, wherein preferably the prongs of a plurality of top members all lie in the same or substantially the same plane. In the preferred embodiment disclosed herein, the channel member is affixed either by adhesive materials or fastening elements to a cable clamp which, in one exemplary embodiment, comprises a pair of matching C-shaped members having flanges, at least one of which can be selectively fastened by a fastener, such as a bolt or a rivet. The clamp is adapted to encircle and compressively engage a cable, such as a telephone wire or electrical wire.

  • Patent number: 5310163
    Abstract: A barrier is fixed on a wall or other perimeter structure by way of support posts. The barrier has a support shaft along which a number of rotatable units are mounted. Each rotatable unit is formed from two interengaged elements, each element having been formed from a length of metal tubing. Part of the tubing has been cut longitudinally to define blades extending from one end of a tubular portion, and splayed outwardly and spaced apart. Two such elements are assembled so that their blades interengage to form one of the units. The rotatable units so constructed are simple to manufacture, but provide an effective barrier.

  • Patent number: 5143354
    Abstract: An attachment to a fence, such as a chain link fence, used to confine a dog, prevents the dog from climbing the fence or using the top of the fence to assist himself in escaping over the fence. The attachment creates a region of instability, superjacent the top of the fence, which will not support the dog's weight and thus does not allow the dog to cling to or push off of the top rail of the fence. The region of instability is created by a freely rotatable roller attachment or a flexible panel attachment, both of which yield under the weight of the canine.

  • Patent number: 5062612
    Abstract: The invention provides an elongate security rail comprising a land extending in the long direction of the rail and which is connectable to the top edge of a wall or the frame of a framed fence. A series of barbed palings one spaced apart on one side of the land, and a series of spikes one spaced apart on the opposite side of the land. The land, palings and spikes are formed integrally from a strip of flat metal and subsequently bent so as to project in a generally upward direction when the land is connected to the wall. This invention also provides a method of making such a security rail.
