Abstract

PURPOSE: To effectively prevent invasion by applying uncomfortable electric touch to an animal to invade by alternately arranging a lot of electrified and grounded conductive planes on a non-conductive mat and applying electric pulses at short time intervals to the conductive planes. CONSTITUTION: At the place to prevent the invasion of small animals, a mat 4 made of a non-conductive material is spread, and a lot of electrified conductive band pieces 10 and grounded conductive band pieces 12 are alternately arranged at intervals on the upper surface of that mat 4 while being electrically insulated each other. Then, series of electric pulses in a short time practically shorter than one second are applied from an electric controller 16 to the respective conductive band pieces 10 at the interval of about one second. Thus, when the animal touches the mat 4, a circuit is completed between the conductive band pieces 10 and 12 adjacent to one part of body of the animal and the inactive electric touch is applied to the animal so that the invasion of animals can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for repelling small domestic or wild animals from places where they may become a nuisance.

More particularly, the present invention is directed to the problem of nuisance animals that turn over kitchen garbage cans or walk around automobiles leaving footprints and scratches on them.

(Prior Art) When kitchen garbage or cars are located in areas where animals come and go all the time, it is very difficult to keep animals away from them. Chemical repellents can help discourage animals from accessing areas such as kitchens. Some of these repellents are made as repellents for dogs and cats and are used in aerosol form or in spray bottles.

Electric fences are known in the prior art for stunning or training animals to stay within certain boundaries, especially for killing rodents and insects.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for keeping animals away from car bonnets, kitchen waste bins, furniture and similar items.

Another object of the invention is to provide a device which does not harm the animal, but which discourages the animal from entering such places.

(Means for Solving the Problems) The present invention comprises a mat made of a non-conductive material that is spread over the above-mentioned location, and a number of conductive surfaces arranged at intervals on the upper surface of the mat. The electrically conductive surface includes two electrically conductive surfaces electrically insulated from each other, one energized and the other grounded, and electrical control means for supplying power to the electrically conductive surfaces. The electrical control means and the conductive surface are such that when an animal contacts the mat, a portion of the animal's body is between an adjacent energized conductive surface and a grounded conductive surface. It closes the circuit and gives the animal an unpleasant electrical sensation.

In a preferred embodiment of the invention, said electrically conductive surface has the form of a strip of electrically conductive material in electrical communication with said electrical control means, so that upon actuation of said electrical control means, said electrically conductive surface has a The strips that are energized and the strips that are grounded are arranged alternately. nq-noted electrical control means, which, in operation, provide electrical pulses of very short duration to the energized strip.

(Effects) The device according to the present invention can be placed on garbage bins in the kitchen, on the hood of a car, on an island, or in a corner of the kitchen. The device of the invention does not harm the object or place on which it is placed, but is uncomfortable to the animal when the animal's body completes the electrical circuit between the current-carrying conductive surface and the grounding conductive surface on said mat. It effectively gives the feeling of electricity. Animals are reminded of the location by the unpleasant electric sensation and do not go near it thereafter. This result is obtained without harming the animal.

(Example) As shown in FIG. 1, the device 2 of the present invention preferably includes:
It comprises a mat 4 made of flexible non-conductive material, which is fixed, for example, on the bonnet of a car or on a kitchen waste bin.

The mat 4 has suitable dimensions and may be rectangular or any other desired shape. Fixing means, for example a magnetic strip 6, are attached along the edge of the underside of the mat 4.

On the upper surface of the mat 4, there are strips 8 forming a large number of conductive surfaces.
are spaced apart in parallel as shown. These conductive strips constitute an electrical circuit in which electrical power is supplied across the mat surface to a number of energized strips 10 and to a neutral or grounded strip 12 between the strips. be done. These strips or conductive surfaces 10.12 are
For animals such as raccoons, spacing of about 1 inch is most effective so that the animal's paws on the mat surface complete the circuit. The strips 10, 12 are arranged parallel to each other on the surface of the mat 4, and the layout of the conductive surfaces is such that a given area of the mat, i.e. 1 or 1.5 square inches, has no adjacent conductive conductors. It is not limited to what is shown, as long as there is a conductive surface and a ground conductive surface, such that a part of the animal's body on the surface completes the circuit. The strips 10, 12 forming this circuit are connected by wires 14 to an electrical control means 16, which in turn is connected to a standard wall socket 18, respectively, so that when energized, the strips 10, 12 are connected at intervals of approximately 1 second to Gives a series of electrical pulses of less than a second duration. The conductive strips 8 are spaced apart and electrically insulated from each other, so that a host animal walking on the surface of the mat can be exposed to one or more pairs of conductive strips, either by one leg or by several parts of its body. , adjacent energizing strip 10 and grounding strip 12
Close the circuit between The power applied to the strip 8 is not intended to harm the animal, but merely to give the animal an unpleasant electrical sensation with a small electric shock and to deter it from re-adhering to the area covered by the mat. .

FIG. 2 shows an example of an electrical circuit for the mat 4 and control device 16 of FIG.

The device of the invention can be used in place of conventional animal repellents and will not damage the textile surfaces or metal surfaces on which it is placed, such as car bonnets. The device of the invention uses very little electrical power and, when energized in place, can effectively deter beds and animals from entering the area for long periods of time.
