    DK 2018 00819 A1 1 The present invention relates to a method for drilling pests from defined areas, for example gate and / or door openings | the wall of a building.
    The invention further relates to a device for carrying out the method according to the invention.
    | for a number of years it has been a problem to keep pests such as rats and mice away from rooms where food and the like are stored that attract said pests. The problem is particularly pronounced when gates and doors to the said premises in - periods are open in connection with loading and unloading of goods, and especially in the periods of the day when the natural daylight is weak, or not occurring (at night) . However, the penetration of said pests through said open gates and doors also occurs during periods of full daylight.
    The said pests are typically controlled with chemicals and poison laid out by trained personnel in locked boxes, to which the pests can access the venom through openings, but where birds of prey and other animals cannot gain access. However, the use of poisons and chemicals in the control of pests has been shown to have an adverse effect on the surrounding environment, just as a build-up of some resistance in the pests to the said poisons and chemicals has also been observed, which has resulted in development of new toxins that are more potent, and possibly therefore more harmful to the surrounding environment.
    Pest control also uses ultrasonic devices that include an electric tone generator that generates high frequency sounds that the pests do not like, be it sounds in the frequency range that includes the pests' anxiety or warning cries. Such scare devices are known for scaring away house martens, rodents and birds.
    The increasing demands on food hygiene have meant that the presence of rats in connection with storage rooms in general, and in particular storage rooms belonging to shops and supermarkets, in particular shops and supermarkets that sell food, can lead to a temporary closure of the supermarket / warehouse in question. , until the authorities have ascertained that the pests have been displaced. The closure results in
    DK 2018 00819 A1 2 financial losses for the owners, and inconvenience to the customers, who have to find alternative shopping places during the closing period, with the risk that the customers move their trade permanently to the alternative shopping place.
    Despite the intensive use of the above-mentioned known methods to control the spread of said pests, as well as to chase away pests, it can nevertheless be unavoidable that these, in particular rats and mice, enter said storage space. Rats and other pests are shy, and usually operate under cover of darkness or at night, where their behavior is not noticed by humans.
    The problem is, however, that said storage space is usually provided with gates which are opened so that the goods to be delivered to the warehouse can be unloaded on pallets or pallet trucks etc. from a truck or semi-trailer. As the goods are also most often delivered in the evening and at night, so that these are as fresh as possible, and can be ready on the shelves the next day, there will often be open gates to the mentioned warehouses for shorter or longer periods. This often means that rats and other pests, in the shelter of the dark, can sneak unnoticed along the outer walls of said warehouses, and into open doorways and doorways, into and stay in the warehouse, where it is partly warmer than outside , and where there is often access to feed in abundant quantities.
    It is thus the object of the invention to provide a method for driving away pests from areas and door and / or door openings, preferably to rooms where food and the like which attract pests are stored, without the use of chemicals or poisons, and a device for practice of the procedure.
    It is realized by the invention that this object can be achieved by a method for driving away pests from defined areas, for example gate and / or door openings in a wall of a building, which is characterized in that air flow at a unit is generated by opening of door and / or door openings, which air flow is routed via nozzles to nozzles | dispensers arranged at or near ground level, spreading the uftstrem in the direction away from the areas, or away from the door and / or door openings, along the wall near said openings, and the area in front of said openings | direction away from the openings.
    The invention thus exploits the phenomenon that an animal, whether a pest or other animal, does not like to be blown in the head
    DK 2018 00819 A1 3 with an air flow. An example of this is if you breathe a dog or a cat, or another animal in the head, then the animal in question will seek away from the air flow. In connection with the invention, a strong air flow is generated at the unit, which is supplied via piping to a dispenser, whose nozzles / openings disperse the supplied air flow at the level where the pests are located (at the terrain surface), and away from the surface or port. and / or doorway from which the pests are to be chased away. The method can further be further improved in that the piping and / or the dispensers are arranged such that ultrasound is generated at the passing air flow, located in the frequency range 20-30 kHz.
    Since an ultrasound whose frequency is located in the frequency range 20-30 KHz is precisely located within the pest anxiety scream of the pests in question, then pests will seek away from, for example, an area or a door and / or a door opening where the air flow, which already annoying to the pest occurs.
    A device for carrying out the method according to the invention is characterized in that it comprises a blower unit for generating an air flow which is - supplied to pipelines connected to at least one dispenser with openings, arranged in or approximately at ground level around a given area, at the sides of, or in a door and / or door opening, which dispenser orients the supplied air flow away from the area or the door and / or door opening.
    This results in a strong air flow oriented away from an area or a door and / or door opening along the ground level, which means that pests that will try to enter the building through the mentioned openings, instinctively and per. reflex reverses, and abandons the attempt to penetrate the room behind the area, the gate and / or the door.
    The blower unit can in this case be in operation constantly or time-controlled so that it is in operation over certain times of the day, where the areas, door and / or door openings are empirically open, but this will partly be too inappropriate from an environmental and energy considerations, and there is also the risk that - the pests get used to the unpleasant air flow. | In order to optimize the operation of the device according to the invention, the fan unit may be connected to a control unit which is connected to at least one detection unit, where the fan unit
    DK 2018 00819 A1 4 The server unit is activated / deactivated by the control unit according to the nature of the signal received from the detection unit (s).
    Hereby it is achieved that the operation of the device is controlled by preselected appropriate parameters. This could be, for example, a door / gate detection unit which sends a signal to the control unit to start the fan when a relevant door / door to a room is opened, and which control unit is arranged so that it stops the operation of the fan after the course of a period of time after receiving a signal from the detection unit that the relevant door / door is closed.
    In connection with the establishment of new premises for storage, there will be an obvious possibility of including the device according to the invention in the new building, in that the dispensing unit can consist of a channel arranged at ground level across said relevant door and / or door openings. with dispenser openings oriented away from the area or the door and / or door opening, and along the external walls adjacent to the door and / or door opening.
    The duct with the dispensers can be embedded in the opening of the door and / or door at floor level, and the piping from the fan unit connected to the duct can also be led into walls or the floor.
    However, there are most existing rooms which are plagued by the possibility of invading pests, and the invention applies to these in that the dispensing units are constituted by air nozzles arranged at the sides of a door and / or door opening, which air nozzle is arranged such that this distributes and distributes the supplied air flow in a flat fan of at least 180 ° in front and parallel to the wall - at ground level, in which the door and / or door opening is located, and out into the area in front of the door and / or door opening.
    Hereby, by placing at least one dispensing unit at each side of a door and / or a door opening, it is achieved that a strong air flow is generated parallel to the terrain surface which chases the pests away.
    It should be noted that the device for carrying out the method according to the invention, in a special embodiment, may comprise both the duct placed in a door and / or door opening and the air nozzles / dispensers at the sides of the door and / or door opening. Such a device will require a more powerful fan unit, alternatively that> each of the embodiments be provided with an independent fan unit.
    DK 2018 00819 A1 In a preferred embodiment of the device according to the invention, this may comprise an ultrasonic flute which generates tones within the frequency range 20-30 KHz by means of the air flow generated from the fan unit.
    This results in the generation of an ultrasound within the frequency range 5 - in which the pests' cries of fear and warning are located. This will amplify the effect of the device, as the sound can be perceived by the pests even before they may be affected by the strong air flow from the dispensers. A double effect is thus obtained, as the first action to drive away the pests is the ultrasound, and if the pests get used to it, the emitted strong air flow through the dispensers will cause the pests to turn around and escape.
    In a further embodiment of the device according to the invention, it may comprise a scent dispensing unit which dispenses scents in the generated air flow which scares away the pests.
    Since the smell of predators and other natural enemies of the pests will cause them to escape, dispensing of, for example, the scent of predators such as mares, mink, cats and other predators, in whose food the pests are included, will have an improving effect of the device, for a pest usually does not seek out his enemies.
    The invention is explained in more detail in the following with reference to the drawing, - where; fig. Fig. 1 shows a door opening comprising a first embodiment of a device for carrying out the method for driving away pests, according to the invention, wherein the dispensing unit is integrated in the floor of the door opening; Fig. 2 shows a door opening comprising another embodiment of a device for carrying out the method according to the invention, wherein the dispensing units are arranged at the sides of the door opening; 3 is a detail side view of a dispenser unit belonging to the one in fig. 2 shows the embodiment of the device according to the invention, fig. 4 is a plan view of the device shown in FIG. 3, and FIG. 5 is a side view of the inner part of the dispenser unit.
    FIG. 1 is a schematic diagram showing a door opening 2 comprising a first embodiment of a device 4 for carrying out the method of chasing away pests, according to the invention, wherein the dispenser unit 6 is integrated in the floor opening floor level 10 of the door opening 8.
    DK 2018 00819 A1 6 The one in fig. 1 comprises a fan unit 12 which is connected via pipes 14, 16, 18 to a duct 20 with dispensing openings 22 for discharging a plurality of air streams 24, illustrated by arrows in the direction away from and parallel to the wall. 26, in which the door opening 2 is located.
    The device shown in fig. 1 is primarily suitable for establishment in connection with new construction of warehouses and premises, but of course also find application to existing construction, where scrapping of gutters for the location of the channel 20 will often be necessary. However, the channel 20 can also be designed as a flat-like tube 20 with dispenser openings 22 in the direction away from, and parallel to, the wall 26 in which the door opening 2 is located. The flat tube 20 is assumed to be equipped with anchoring options to / in the surface in the door opening 2.
    FIG. 2 shows a door opening 2 comprising another embodiment of a device 4 for carrying out the method according to the invention, wherein the dispensing units 6 are arranged close to the sides 28, 30 of the door opening.
    As can be seen, the device in this embodiment comprises a blower unit 12, which is connected via pipes 14, 16, 18 to dispensers 6 in the free ends of the pipes 16, 18. The dispensers 6 are provided with dispenser openings 22 (see Fig. 3). ) for discharging a plurality of air streams 24, illustrated by arrows 24 in the direction - away from and parallel to the wall 26 in which the door opening 2 is located, and out into the area 32 in front of the door opening 2.
    FIG. 3 is a side view of an embodiment of a dispenser unit 6 belonging to the second embodiment of the device 4 according to the invention. The dispenser unit 6 is connected to the pipe 16, 18 for supplying air from the fan unit 12, via the pipe
    The dispenser unit 6 comprises a housing 34, in which there is an upwardly curved surface 36 oriented upwards towards the tube 16, 18, which serves to guide the supplied air flow from the fan unit 12 in the direction of slit-shaped dispenser openings 22 between a bottom plate 38 belonging to the dispenser 6 and the housing 34 The curved surface 36 serves to counteract pressure loss and turbulence in the dispenser 6. The bottom plate 38 is typically located on the ground surface 10 outside the door opening 2.
    As indicated in FIG. 3, the dispenser unit 6 in this embodiment comprises a whistle unit 40, which generates tones within the frequency range 20-30 KHz, which is the frequency range for pest anxiety and warning cries. The tone is generated - immediately after a certain air flow through the dispenser is generated by the fan unit 12.
    DK 2018 00819 A1 7 Fig. 4, which is a top view of the device shown in FIG. 3, shows how the dispenser 6 is arranged with the curved surface 36 extending substantially over half of the base surface area of the housing 34, and spaced triangular distributing bodies 42 whose pointed ends 44 are oriented towards the center of the dispenser 6. Distributing the bodies 42 ensures an approximately uniform distribution of the air supplied from the fan unit 12 out through the dispenser openings 22.
    FIG. 5 is a side view of the inner part of the dispenser 6 shown in fig. 4, where the housing 34 is not shown. As can be seen, the manifold bodies 42 comprise recesses 46 intended for supporting the housing 34.
    Without renouncing the right to other possible modes of operation for the device 4 according to the invention to drive away pests from defined areas, for example gate and / or door openings 2 in a wall 26 of a building, the following mode of operation can be referred to an example in which a door opening. But the opening could also consist of a door opening or other opening, or an area where free passage for the passage of pests is desired.
    The door (not shown) in the door opening 2 is opened by activating a pushbutton (which - provided actuator-driven door opening systems) the door control unit sends a signal to the control unit of the fan unit 12, which activates the fan unit, thereby generating a strong air flow via the dispensers 6, via dispenser openings 22, are distributed in partial air flows 24 in the direction away from the door opening 2 and also parallel to the wall 26 in which the door opening 2 is located.
    Depending on the embodiment of the dispenser 6 in question, the partial air flows 24 are distributed in a linear flow profile directed away from the port opening 2 as indicated in fig. 1, or in a fan-shaped flow profile, starting from two dispensers 6 from each side 28, 30 of the door opening 2, which fan-shaped flow profiles extend at least 180 ° away from and parallel to the wall 26 and the door opening 2, and out in front of the door opening, as shown in fig. 2. When the air flow is supplied from the fan unit 12, the whistle unit 40 is activated (cf. Fig. 3), whereby an ultrasound is also emitted within the frequency range 20-30 KHz, which is the frequency range for pest anxiety and warning cries.
    In special cases, the device 4 according to the invention may be equipped with an odor dispenser (not shown) which emits odors of predators and natural enemies of the pests which it is desired to chase away.
    DK 2018 00819 A1 8 The inventors have recognized that the device can assume many other embodiments.
    shapes other than those shown in the drawing and described above, for example the air flow could be generated by a compressor, just as the arrangement of the dispensers could assume other designs, adapted to current operating conditions, but this
    Does not alter the inventive aspect of exploiting pests' instinctive fear of blowing air, by emitting a strong flow of air in and around an area, or a gate and / or doorway, and also exploiting the flow of air to a frightening sound, to prevent pests from passing, as pests will instinctively turn around when they sense the air currents emitted via the
    The buckle openings belonging to the device according to the invention.
    This also ensures that the pests are chased away without the use of poisons that are harmful to the surrounding environment.
