FR2693081A1 - Electric bird-scarer for buildings - uses mains-fed pulse generator connected to bare conductor continuously or intermittently supported along roofs and ledges - Google Patents

Abstract

The mains-fed (2) generator (1) delivers (4) low value (11mA) current pulses, at least 1 second apart, to a bar conductor (3), strung along pin insulators (6) fixed on the ridge, ledge, etc., to be protected. The other output terminal (5) serves as an earth-return connection. The live conductor (3) may comprise several stainless steel strands woven with nylon fibres into a flat strip 10 or 20 mm wide, laid over a similar earthed strip, twice as wide, separated from it by an insulating strip, the whole fixed by adhesive to the protected structure. The live and earthed conductors may take the form of parallel rails, laid longitudinally 10 mm apart in an insulating strip 20 mm wide. USE/ADVANTAGE - Repels pigeons, etc., without injuring them. More effective than methods currently used.

Description

DESCRIPTION
The present invention relates to a device for hunting constructions, pigeons and other animals, degrading them.

 Various procedures have been used to keep pigeons away from buildings; but they did not all provide the expected result.

 Some of them, such as nets, have been shown to be dangerous to birds. Caught in the mesh, they are condemned to slow agony.

 Others, like glue and repellents, are of limited effectiveness over time.

 As for the peaks, they limit access and maintenance and are only suitable for the treatment of a moderate surface.

 Finally, these various processes often distort the buildings they are supposed to protect.

 As for the electrical systems, already existing, they are archaic and cannot be used without problem, on all supports. Protection by electrical lines of a roof would make maintenance delicate and dangerous.

 The device according to the invention overcomes these drawbacks. According to a first characteristic, it indeed has the possibility of laying on buildings, a conductive wire of electrical pulses of low intensities 11mA, the interval between 2 pulses being greater than one second. It is arranged so that the animal which comes to land on the protected parts, is put in contact with this said thread, and chased without causing it damage.

According to particular embodiments:
- The insulator which can be cylindrical in shape, a notch allowing the passage of the electrical pulse wire can be provided on its upper perimeter, as well as on its summit diameter; a slope can be planned in order to isolate the water drops.

Its fixing can be provided under its lower part by a tapped hole. This insulator can be used for the protection of masonry parts and zinc works. To ensure the transport of electrical pulses, strands of nylon braided with stainless steel wires form a wire with a diameter of 25 mm, which is stretched between the insulators and connected to an electrical pulse device.

 - the protective strap for roofing, formed by the assembly of a 20 or 40 mm braided nylon strap with stainless steel wires connected to the ground, on which is glued the whole of an insulating strap under strap of 10 or 20 mm braided nylon with stainless steel wires through which the pulses pass. This sembiage ace is glued directly to the tiles.

 - the insulating strip of triangular or rounded profile - in order to ensure good insulation between the two conductors during atmospheric disturbances at the upper surface of which feels two rails incorporated, one of which can be a conductor of pulses and the other the return To the earth. It can be fixed by gluing or screwing. This band can be used for the protection of monuments and listed buildings.

The accompanying drawings illustrate the invention
Figure 1 shows the diagram of this electrical system.

 FIG. 2 shows the insulator enabling buildings to be protected by a conductive pulse wire.

Figure 3 shows the device according to the in
vention allowing the protection by strap, of
roofs.

Figure 4 shows the device according to the in
vention allowing protection by insulating tape,
monuments.

Referring to Figure 1, the device com
carries an electric pulse generator (1) connected to the mains at 220 v using a plug two
poles plus earth (2), an electrical circuit comprising
a single pulse-carrying wire (3), connected directly
generator (1) on terminal (4), isolated from
the building mass by insulators (6) figure
2, which can be attached directly to the infras
structures of the building, by screwing, either: using
of hooks to be screwed on the front, or threaded rod in
nylon with nut to protect the gutters, or
still on a turntable with enough area to
allow its bonding, on sealing for example.

These so-called insulators are placed at regular intervals
linkers, depending on the terrain to be protected and so
avoid the deflection of the lead wire (3).

The insulator in FIG. 2, of cylindrical shape,
at the top of which is provided a notch (7) allows
both the passage of the electrical pulse wire (3),
tensioned and knotted for tightening using the notch (75),
planned within its perimeter. A slope (8) is planned
in order to isolate the drop of water, and finally, under its par
lower tie can be provided with a tapped hole (9)
allowing its fixing. The height of the insulator
can vary from 25 mm to 40 mm.

FIG. 3 represents the protective strap,
formed by two straps, one (10) of 10 mm or 20 mm
depending on the case, and the other (11) of 20 or 40 mm, in
braided nylon in which threads are incorporated
stainless steel (12), and isolated from each other by a strap
insulating (13). The whole being fixed by gluing, for
protection of electrostatic non-conductive supports.

 The stainless steel wires (12) of the strap (10) are connected to the sector at 220 v, by the terminal (4) in figure 1, those of the strap (it) are connected to earth by the terminal (5) in figure 1.

 The insulating strip in FIG. 4 is formed of a triangular or rounded insulating profile (14), on the upper surface of which two rails (15) are incorporated, one of which is a conductor of pulses and the other the return to the Earth. The space between each rail and the top of the profile can be 5 mm.

 By way of nonlimiting example, the insulating strip will have dimensions of the order of 20 mm for the base and a height of 5 mm.

 The device according to the invention is particularly intended for hunting pigeons from constructions, without causing damage to animals and without harming the aesthetics of the protected architecture.
