DE1051560B - Electric scare device for driving away birds - Google Patents

Description

The invention is based on the object of birds, especially starlings, blackbirds o.a. smaller songbirds, when To chase away tearing off especially the red berries on fruit carriers, trees, bushes or the like by fright, or to prevent young plants from being pulled out after the seeds have sprouted. The birds! fly in from above and sit a little below the Berries or plants. The solution to this task is based on the assumption that the wires of a two-pole current conductor, which is connected to an induction power source, to be arranged on an insulator so that it is in irregular structures, trees or bushes, easily and appropriately attached and after the maturity can be removed again. When the birds sit with their toes on the conductor there this is shocked by power failure. This device is only to be installed temporarily, as the birds are useful and not intended to be chased away entirely, and do not hinder the growth of the fruit-bearers may be. The device is also to be designed in such a way that the birds are like on one Lay a thin twig so that the toes don't cramp up when frightened and the birds are dead fall over.

There are already devices for deterring birds from building soiling known to consist of one or more parallel to each other on or above the building on insulators laid conductors for the emission of high-voltage electricity exist. In one case, the bird is said to be at Sitting and at the same time touching the conductor with the springs a shock through impulses sent through Receive electricity. Such systems can be used in fixed buildings, but not in irregular ones Forms such as trees or bushes can be used because the wires are taut in the foliage are hindered by this and also hinder this and several wires are not constantly parallel can be held to each other.

Another known device with one or more wires is intended to keep harmful animals, game, rats or mice or other soil animals away from rooms or cultivated areas by the physiological effect of the force fields emanating from the force conductors on the animals. The current should not have an immediate effect, as is the case with pasture fences. This system is based on other findings, which undoubtedly do not apply to birds, as experience has shown that they sit on lines of all kinds, including high-voltage lines, to rest without damaging them. Finally, electric flycatchers with two current conductors connected to the two poles of a power source are known, which are positive and negative side by side via a square frame

are stretched to attract flies on the frame, which in a horizontal position over means to attract the flies is arranged to kill when the whole body of the flies touches both wires. this device does not show the object of the invention for use against birds and can be used for this object also do not simply use it for attachment to irregular structures.

In contrast, the device according to the invention is characterized in that the wires are different Poles spiral on a z. B. made of plastic, serving as an insulator rod or cable are tightly wound next to each other in the strength of a thick wire or a branch, which means Clamping devices on the fruit carrier itself or to protect plants on a z. B. made of wood or Glass existing insulating pad can be attached and used as a power source for the multi-pole Wires an induction power source is used. The rod in the form of a plastic cable can also have a appropriate coloring, and finally the two can be found on the cable positive and negative wires different - e.g. B. the positive in pure copper color and the negative by virtue of a coating - be tinted.

The device according to the invention makes it possible to conduct current conductors over irregular structures, trees, To relocate bushes or the like. The carrier cable according to the invention has the task of having different poles To carry wires and also to serve as a useful attachment when the birds are sitting. It leaves to adapt to many circumstances and enables the frightened birds to look after what they have suffered Shock to be released again by the electric shock. By flying away, the birds are in front sustaining permanent damage and preserving the gardens for useful purposes. The device is light, nevertheless robust and easy to install

and as a mass-produced item, i. H. economically producible and satisfies a long-standing need. The device thus produces substantially new, surprising technical effects. The subject matter of the invention is shown, for example, in four figures, of which FIG. 1 shows a plan view, FIG. 2 shows a view, FIG. 3 shows a section A-B and FIG. 4 shows a general illustration. On a plastic cable 1 of the thickness of a thicker wire, two thin copper wires 2 positive and 3 negative continuously spirally firmly wound are expediently attached at a relatively small distance, one of which, for. B. the one to the negative pole, primarily to distinguish it on the cable, has a different appearance than that to the positive pole, for example through a coating. A plastic cable end 1, which carries the wires 2 and 3, is used for arrangement on beds of plants on a base 4, e.g. made of wood, with insulators 5, 6, e.g. B. arranged from glass or the like. The leads 2 and 3 are connected at their ends 7, 8, at the left end of the cable 1 to an induction current source 9, which is fed by a power supply system or a battery 10, with the involvement of a converter and / or a transformer 11. As is known, sit down the birds before flying into plants, bushes or trees in front of them and first observe the places from which they can get to the fruits. Therefore z. B. for plants the cables on documents such. B. on wooden boards, isolated by glass insulators, laid directly on the ground in front of the plants. In the case of bushes or trees, the documents are arranged at the appropriate height. The devices are designed only when the fruit is ripening. When it rains, the power supply is switched off because the birds then hold back. The plastic cables with the wires are expediently produced in certain lengths from a continuous roll and can be used individually or together. The color of the plastic cable can be white or dark, e.g. B. be green, since light colors serve as a deterrent and dark colors simulate confusable objects. Patent claims: 1. Electric scare device for repelling birds using isolated, connected to the two poles of a power source of relatively low amperage Wires, characterized in that the wires spiral on a z. B. made of plastic existing rod the size of a thick wire or a branch serving as an insulator are wound up by means of a clamping device on the fruit carrier itself or to protect Plants on a z. B. made of wood or glass existing insulating pad can be attached can, wherein an induction current source is used as the current source. 2. Apparatus according to claim 1, characterized in that the plastic cable is an appropriate one Has coloring and that furthermore the two positive and negative wires on the cable are tinted differently, z. B. the positive has the pure copper color and the negative has a coating. Considered publications:
