Description
- The present invention relates to an apparatus for repelling birds, and in particular to an apparatus for repelling birds capable of supporting significant weight.
- Birds often perch on upward facing surfaces of buildings, and can in the process cause a nuisance. Whilst significant problems may be caused to buildings, the problem of nuisance birds is even greater where the surface landed upon by the birds is one used by aircraft for the purpose of landing and take-off. In this situation, the presence of birds may be extremely dangerous. Helicopter landing pads present a particular problem, especially those located on oil rigs, since the oil rig is likely to be the only structure within a large area upon which sea birds may land. Furthermore, they present a very harsh environment in which to operate any apparatus.
- Other forms of vermin also present problems which may be addressed by the use of apparatus for delivering an electric shock to the vermin in question. For example, such apparatus may be used to deter rats from entering buildings.
- A number of solutions to the above-mentioned problem have been posed. For example, U.S. Pat. No. 6,006,698 describes an electrical bird repelling device comprising a base made of an insulating material, and one or more electrically conductive rails disposed on the base. An electric potential is applied to each of the rails such that there is a potential difference between the two rails. When a bird lands on the electrical device and bridges the two rails, current flows between the two rails and the bird is given a mild electric shock which repels the bird from the area of the electrical device.
- In the device described in U.S. Pat. No. 6,006,698 the electrically conducting metal rails equipped with blades are laid in a base material formed of a polyvinyl chloride (PVC) extruded profile having a hardness of 83. The base has a very low height (2.4 mm) the purpose of which is to assist the device blending in with the surface from which birds are to be deterred. The upstanding spikes prevent nesting on the device and are also said to create a noise that is disliked by birds.
- DE29610206U1 describes another electric-shock device adapted to deter birds, and comprises a base upon which are mounted alternate positive and negative upstanding tracks. This device is adapted to be mounted on edges of buildings and the like to prevent birds perching thereon.
- Keeping surfaces that are to be landed on by aircraft free of birds presents particular problems. Using an electric shock deterrent, one must either rely on a device of the type described above in U.S. Pat. No. 6,006,698 laid on the edge of the surface to deter birds from landing on the whole surface, or alternatively, the device must be either be embedded into the surface, or the device must at least partially cover the surface.
- EP1382243 describes an electric-shock sheet which may be laid out across a surface to be kept free of birds, or other vermin. However, such a sheet is not capable of supporting a significant weight without itself being damaged.
- DE G 9405347 describes an electrified mat to protect against animals and adapted to be laid out across a surface, such as the floor of a garage or carport. The mat is laid out across the surface and a car may drive over it. The mat comprises a
carrier layer 2 andelectrified zones 3, which are isolated from each other. The car driver switches off the electrical supply to the mat to reach the vehicle parked in the garage. The construction of the electrified mat in DE G 9405347 comprises a base, a plurality of exposed live wires extending one way across the carrier layer and a plurality of spaced apart clips extending normal to the direction of the live wires and holding them in place. - Whilst the mat described in DE G 9405347 does relate to a mat for use on surface, and for a vehicle to traverse over the mat, the mat is intended for use indoors. The arrangement of the wires would not be conducive to a long service life outdoors. Further, the mat would not appear from the drawings to have significant strength.
- It would therefore be desirable to provide an improved apparatus for delivering an electric shock.
- According to the invention there is provided an electric shock delivery apparatus comprising a base of an electrically insulating material, the base having formed therein a plurality of channels, the apparatus further comprising a plurality of electrically conductive elements, each associated with a respective one of the channels, wherein the cross-sectional shape and dimensions of the channel and the cross-sectional shape and dimensions of the electrically conductive element substantially correspond.
- Advantageously, the electrically conductive element comprises a conductive polymer material, the conductive element is formed into the said shape and dimension by forming the said conductive polymer material. The electrically conductive polymer may be formed into shape by extruding or moulding, for example.
- The electrically conductive element is preferably formed such that it yields when subjected to a load, for example when a helicopter lands on the apparatus and rests upon one or more of the electrically conductive elements those elements yield in reacting to the force exerted thereon by the helicopter.
- Preferably, an electrical conductor, which advantageously is metallic, is encased in the conductive polymer material, and more preferably the electrical conductor is in the form of a wire or a mesh. Preferably, the electrical conductor extends longitudinally through the conductive polymer. The electrical conductor may be situated towards the centre of the conductive element, or may be situated towards an outer face of the conductive element. More preferably, the electrical conductor is situated just below the upper surface of the electrically conductive element. Still more preferably, the electrical conductor is situated approximately 0.5 mm below a surface, preferably the upper surface, of the conductive element.
- The electrically conductive polymer may comprise a polymer loaded with carbon black. Alternatively, the conductive polymer may comprise a polymer loaded with small metal pieces, such as metal filaments.
- Preferably, the electrically conductive elements are so shaped and dimension that when installed in one of the said channels in the base, the upper surface of the electrically conductive element lies in substantially the same plane as the upper surface of the base and advantageously, protrudes just above the upper surface of the base. This ensures good contact between the bird's foot and the electrically conductive elements.
- Advantageously, the channels and the electrically conductive elements have a dovetail cross-sectional shape.
- The electrically conductive elements each comprise upper and lower surfaces extending between spaced apart side walls. Preferably, at least the corners where the lower surface joins the side walls are rounded. This provides the advantage that the electrically conductive elements may be more easily inserted into and removed from the base.
- The base may be formed of a rubber material, which is preferably strongly resilient and hard. In one embodiment the base includes drain holes.
- The base is advantageously formed of a material which is sufficiently deformable to allow the base to adopt a shape substantially corresponding to the shape of the surface upon which it is laid.
- Preferably, in use the apparatus is laid out on a surface an attached thereto by means of adhesive.
- In use, adjacent electrically conductive elements are connected alternately to a positive electrical current and to earth, or a negative electrical current respectively. In this way, when a bird lands on the apparatus with its feet straddling adjacent electrically conductive elements electric current passes from the positively charged element, through the bird, to the earthed or negatively charged element. Preferably, the electric current discharging through the bird is sufficient to shock, but not kill the bird.
- By mounting the electrically conductive elements in channels formed in a base, and by forming the electrically conductive elements in a shape corresponding to the shape of the channels, the apparatus is capable supporting very heavy loads. For example, the apparatus may be laid out on a helicopter landing pad, and a helicopter may land upon it, without causing significant damage.
- Where the apparatus is deployed on a surface over which personnel are required to walk, for example a helicopter landing pad, a switch would be provided in the electrical supply to the apparatus. The electrical supply may then be switched off when personnel need to walk over the apparatus to and from the helicopter.
- Use of the ramp is not confined to use on helicopter landing pads or take-off and landing facilities for other types of aircraft. The apparatus may be deployed around the edges of buildings, or on ledges in the same way that other devices of the prior art are deployed. In such an example, the apparatus may comprise two or three or four channels for example, with the size of the base being specified to fit on the surface where the apparatus is to be used. For such uses the materials from which the base and the electrically conductive element are formed need not be so strong, since they would not need to carry the weight of a large vehicle. Further, the material of the base may be specified such that it allows the apparatus to rolled up.
- In the drawings, which illustrate preferred embodiments of an apparatus for delivering an electric shock according to the invention, and are by way of example:
-
FIG. 1 is an end view of the mat in its assembled form; -
FIG. 2 is an end exploded view of the mat illustrated inFIG. 1 ; -
FIG. 3 is a cross-sectional elevation of an electrically conductive element of the mat illustrated inFIG. 1 or 2; -
FIG. 4 is schematic representation of the mat illustrated inFIGS. 1 to 3 ; -
FIG. 5 a is a schematic representation of an alternative embodiment of the invention; -
FIG. 5 b is a schematic representation resembling more closely the actual size of the mat and its component parts. - Referring now to
FIGS. 1 and 2 , the apparatus according to the invention is embodied in amat 1 comprising abase 2 formed of a non-conductive material, such as rubber or neoprene for example and having formed therein a series ofchannels 3. As can be seen fromFIGS. 1 and 2 , the shape of the channels is dove-tailed in cross-section. Thechannels 3 receive electricallyconductive elements 4, which in the present example comprise a metallicconductive wire 5, formed of copper for example, surrounded by aconductive polymer 6. Theconductive polymer 6 allows theconductive element 4 to be formed into a dove-tailed shape that is dimensioned so as to fit tightly into achannel 3. - The
mat 1 is preferably assembled by aligning theconductive elements 4 with thechannels 3 of thebase 2, such that theelements 4 are positioned above thechannels 3. Thebase 2 andelements 4 are then passed between rollers resulting in theelements 4 being pressed into thechannels 3. - The shape of the
channels 3 and the corresponding shape of theconductive elements 4 provides two advantages. First, the conductive elements are conveniently secured in thebase 2 without the need for any adhesives or other fasteners, and second the manner of securing theconductive element 4 in thebase 2 means that the greater the amount of force exerted on the upper surface of themat 1, the more securely theconductive elements 4 are held in place, whether the force exerted on the mat is exerted between or on theconductive elements 2. - As can be seen from
FIG. 3 , theedges 7 of theconductive elements 3 are rounded, which facilitates insertion and removal of the conductive elements from the base. - The distance between the
conductive elements 4 is small, thereby minimising the possibility of a bird landing on the mat and failing to extend a foot across two adjacentconductive elements 4. For example, the upper surface of the conductive element may be approximately 7 mm, and distance between adjacent conductive elements may be approximately 13 mm. - The
mat 1 is laid on a surface, for example, the upper surface of a helicopter landing pad, such as might be found on an oil rig, or the flight deck of an aircraft carrier. As can be seen fromFIG. 4 , thebase 2 may be provided withdrainage holes 8, which in use are aligned with drainage channels of a supporting structure. - The
mat 1 may be attached to a surface by means of adhesive. The surface to which the mat is to be attached is cleaned, adhesive is applied to the underside of the mat (without applying adhesive over the drainage holes 6) and/or the surface to which the mat is to be attached. The mat is then presented to the said surface, pressed down firmly to remove any air bubbles and the adhesive is allowed to cure. -
FIGS. 5 a and 5 b illustrate an alternative embodiment of a mat of the invention. Parts common to the embodiment illustrated inFIGS. 5 a and 5 b and the embodiment illustrated inFIGS. 1 to 4 have been given like reference numerals, with the addition of the symbol ′ to the reference numerals inFIGS. 5 a and 5 b. - The principal difference between the embodiment of
FIGS. 1 to 4 and the embodiments ofFIGS. 5 a and 5 b lies in the construction of the conductive elements. Whereas inFIGS. 1 to 4 the electricallyconductive elements 4 comprise a metallicconductive wire 5 surrounded by aconductive polymer 6, in the embodiment ofFIGS. 5 a and 5 b theconductive element 4′ comprises ametallic mesh 5′ surrounded byconductive polymer 6′. Theconductive polymer 6′ may be of the same formulation as described above. In the example, themetallic mesh 5′ is substantially flat and is situated just below the upper surface of theconductive polymer 6′, in fact themetallic mesh 5′ is situated about 0.5 mm below the surface of theconductive polymer 6′. - As with the embodiment illustrated in
FIGS. 1 to 4 , theconductive polymer 6′ allows theconductive element 4′ to be formed into a dove-tailed shape that is dimensioned so as to fit tightly into achannel 3′. -
FIG. 5 b shows themat 1′ in a scale closer to actual size than the scale indicated inFIG. 5 a. In actual size, theconductive elements 4′ and thebase 2′ are not as deep as indicated inFIG. 5 a. - The mat of the invention is sufficiently strong to bear the weight of an aircraft, such as a helicopter, without damage occurring to the copper wire encased in the conductive polymer.
