UTILITY MODEL REGISTRATION Electrical protection device against birds DESCRIPTION

1 SCOPE

1.1 General:

The invention can be used on buildings of various types and designs to ward off birds and other flying biological objects. It is harmless to humans and higher-order living beings. It can be installed quickly and is maintenance-free. The modular design makes it possible to set up the system in a very short time. The protective device is environmentally friendly.

1.1.1 State of the art/tested publications:

Physical and toxic methods have been used to control birds for several years. What they all have in common is the relatively high level of effort and the sometimes incalculable risks and side effects. There are various bird deterrent systems on the market with different designs and modes of action. In the mechanical field, a defense system that works with defense spikes has been disclosed (DE 42 36 351). No relevant publications on the subject of protective devices for electrical defense systems could be found during research.

1.1.2 Problems:

Mainly in the core areas of cities, the increasing food supply has attracted a large number of birds, especially feral pigeons. Due to these circumstances, pigeons in particular have proliferated rapidly and represent a potential hygiene hazard that should not be underestimated. The dangers to buildings are as follows:

-especially pollution by pigeon droppings

-Damage to the building structure caused by pigeon excrement

-irreparable damage to windows, parapets, gutters, antennas and other technical

Facilities which are accessible to pigeons.
40

In recent years, various systems have been put into operation that operate according to different principles:

-with sound, to drive away the animals, Disadvantages: nuisance to residents, decreasing
Effect.

-with toxic agents, Disadvantages: Danger for other birds and animals, carcasses contaminate the

Building.
-Devices designed to scare away the animals, e.g. by using natural enemies of pigeons,

Disadvantage: The effect diminishes as the pigeons become accustomed to it.
-Safety devices, disadvantage: very maintenance-intensive, high costs

-Electrical systems: to ward off attempts by pigeons to approach, disadvantages: mostly simple
High-voltage installations with the risk of fire or killing of animals.

1.1.3 Solution:

This invention presents a protective device that does not have the aforementioned disadvantages. It can be used to create defined parameters to deter pigeons and the animals are safely driven away. The deterrent effect means that birds no longer fly towards them. Buildings and residents are safely protected from overpopulation and the associated disadvantages. As a system, it requires little energy, is environmentally friendly and does not harm the animals concerned. It is easy to install and maintain.

2. DESCRIPTION of the protective device

The invention relates to an arrangement according to the preamble of claim 4. The arrangement according to drawing 960502 consists of the following components/elements and is constructed as follows:

2.1 Structure: Naming of the individual components / elements / list of reference symbols

2.1.1 Pos. 1 Seat electrode (1) 2.1.2 Pos. 2 Base or mounting plate (2) 2.1.3 Pos. 3 Quenching electrode (3) 2.1.4 Pos. 4 Adhesive strips (4)

2.3 Structure: Drawing of the mechanical structure

See FIGURE 1, drawing 960501

2.2.1. Procedure: Description of the functional sequence

The approaching bird primarily lands on protruding parapets, balustrades or other building components that allow it to land safely. The form of the protective device used here allows the birds to land in a targeted manner on surfaces on buildings, e.g. roof elements. The birds place their claws on the perch electrode (1) to settle down. However, they touch the deterrent electrode (3) and, depending on the physiological state of the bird, a more or less conductive connection is established between the perch electrode (1) and the deterrent electrode (3). This causes a current to flow, which means that the high voltage of several kilovolts applied causes the bird to receive an electric shock on its claws. The level of current flowing through the claws is harmless to the bird and does not cause any damage. Commercially available electric fence security devices are used here, which work with current limitation. These devices have been working perfectly for decades and without any danger to humans or animals. This causes the bird to fly away immediately. The reminder effect and the warning calls to flying companions guarantee that the desired areas remain permanently clear.

3, SECURITY

The protective device is completely insulated from other components by the fully insulated base plate (4). In the version with adhesive foil, the discharge of currents can be reliably prevented. In connection with commercially available electric fence devices, the safety of the system is fully guaranteed by various circuits in the generator section (current limitation, permanent short-circuit shutdown). Due to the low current intensity, there is no danger.
