Description

[0001] The invention relates to a shading device for shading and / or closing a building opening, at least comprising a plurality of slats, wherein the slats are each movably mounted by means of guide pins in at least one lateral guide rail and can be moved up and down, intermediate openings are present between adjacent slats when the slats are at least partially lowered, and the slats each have at least one separate voltage-carrying conductor, wherein the conductors can be alternately supplied with a first voltage potential and a second voltage potential, so that when voltage is applied between adjacent slats an electric field is formed which prevents insects from moving through the intermediate openings.

[0002] The invention further relates to a building control / automation system and a building.

[0003] Annoying insects, especially mosquitoes, are a constant nuisance, especially during the warmer months, and can significantly impair quality of life, for example, through sleep disturbances or itchy and painful bites. Climate change and globalization are contributing to their increasing spread, even in European latitudes. Insects are also becoming increasingly important as vectors of disease for humans and animals. Diseases such as malaria, yellow fever, dengue fever, chikungunya, West Nile fever, and certain parasitic worms can be transmitted by mosquitoes. Due to invasive vector mosquitoes such as the Asian tiger mosquito, this aspect is also becoming significantly more important in Europe.

[0004] Conventional methods of mosquito, fly, and pest control primarily involve blocking insects from entering a building. This means that windows or doors must either remain closed or be fitted with a thin-mesh insect screen. Insect screens are available that are permanently mounted on the window or door and are relatively transparent, or, in more robust versions, even scratch-resistant. The disadvantage of insect screens is that they must be installed on doors and windows as an additional physical barrier. However, these barriers are susceptible to accidental contact or damage by pets. They also impair the overall appearance of a building, both inside and out. Soiling of the insect screen fabric from household dust and environmental influences is a further disadvantage. Furthermore, these screens restrict ventilation and visibility.

[0005] Alternative methods for repelling or destroying insects include the use of pesticides or bait and trap systems. However, these often kill not only annoying mosquitoes, but also beneficial insects such as butterflies and bees. Furthermore, the chemicals used, while effective at deterring insects, can be hazardous to the health of children, pets, and sensitive individuals.

[0006] Another method is electronic repellents. These generate sound at frequencies that can repel insects. However, this method is generally not very effective.

[0007] There are various publications on the subject of insect protection / repellency, for example: The publication US 2010 / 0053935 A1 describes a type of mosquito repellent lamp that acts as a sterilizer, mosquito repellent, deodorizer and air purifier, and also serves as lighting.

[0008] The document US 2019 / 0261636 A1 relates to a mosquito repellent patch, and in particular to one that can be easily adhered to the human body, personal belongings or any other object in order to keep mosquitoes away.

[0009] The US design US D754,278 S shows a decorative design for a mosquito repellent clip.

[0010] The document JP 2001136890 A relates to an electric mosquito catcher that can be used outdoors in a small size using a dry battery as a power source.

[0011] However, all known variants of insect protection / repellency are either cumbersome, ineffective or associated with unpleasant side effects.

[0012] The publication EP 3697207 B1 describes a method for repelling mosquitoes, or rather, how mosquitoes can be prevented from entering houses through open windows or similar devices. It describes a system that uses high voltage to generate an electric field between the slats of a Venetian blind or Venetian shutter, preventing mosquitoes from entering the building. This is known as mosquito repelling. The mosquitoes, and thus other insects such as butterflies or bees, are not killed by the electric field.

[0013] In this system, the slats of the Venetian blind are alternately applied to different voltage potentials, creating a potential difference between adjacent slats that leads to the formation of an electric field. The slats themselves serve as electrodes or voltage-carrying conductors. With a slat spacing of 10 mm to 30 mm, high voltages of ideally 3.5 kV are applied to create an electric field that deters mosquitoes and other insects from passing through, but does not kill them.

[0014] The disadvantage of conducting voltage through the slats, however, is that short circuits and even malfunctions can occur in rain or high humidity. Furthermore, touching the slats can cause an unpleasant electric shock.

[0015] As general state of the art, reference is made to the documents DE 20 2019 000 228 U1, DE 10 2016 117 770 A1 and DE 10 2021 210 642 A1.

[0016] The object of the invention is to create an improved system for insect protection / repellence which eliminates the disadvantages mentioned at the beginning in the prior art.

[0017] This problem is solved by the features of the independent patent claims. Advantageous developments of the invention are the subject of subordinate claims.

[0018] The inventors have recognized that the system known from document EP 3697207 B1 for generating an electric field on the slats of a Venetian blind to repel insects can be improved, in particular made safer.

[0019] Accordingly, the inventors propose to improve a shading device, in particular a Venetian blind or a Venetian blind, for shading and / or closing a building opening, at least comprising a plurality of slats, wherein the slats are each movably mounted by means of guide bolts in at least one lateral guide rail and can be moved up and down, intermediate openings are present between adjacent slats in an at least partially lowered state of the slats, and the slats each have at least one separate voltage-carrying conductor, wherein the conductors can be alternately subjected to a first voltage potential and a second voltage potential, so that when voltage is applied between adjacent slats an electric field is formed which prevents insects from moving through the intermediate openings, in such a way that at least the conductors,whose voltage potential is different from ground, have insulation.,

[0020] The shading device is preferably a Venetian blind or Venetian shutter in the familiar design with a multitude of slats, each movably mounted in lateral guide rails by means of guide pins. The slats can be tilted about their longitudinal axis as required and raised and lowered, either manually or electrically. When the slats are at least partially lowered, intermediate openings exist between adjacent slats, through which insects can fly in conventional Venetian blinds or Venetian shutters. The slats can be made of various materials, primarily metallic materials, such as aluminum, as well as non-metallic materials, such as plastic or wood.

[0021] To generate an electric field, all laminations preferably have a conductor to which a voltage potential is applied. The voltage potential alternates, meaning the conductors are alternately subjected to a first voltage potential and a second voltage potential. To simplify this, we will refer to alternating laminations or even and odd laminations below. If you count the laminations from top to bottom, the even-numbered laminations would be at a first voltage potential, and the odd-numbered laminations would be at a second voltage potential. The second voltage potential is either the inverse of the first voltage potential in magnitude or equal to zero.

[0022] During operation, i.e., when voltage is applied, an electric field forms between adjacent slats in the intermediate openings, preventing insects from moving through the intermediate openings. The voltage, or rather the strength of the electric field, is selected so that the insects are merely repelled by the electric field and do not fly through, but are not killed. A voltage that is too low creates an electric field that is too weak and does not deter insects. A voltage that is too high creates an electric field that is too strong and kills the insects, which is what the invention is fundamentally intended to prevent.

[0023] The optimal voltage depends on the distance between adjacent slats and their width. The greater the distance and the wider the slats, the greater the applied voltage must be to generate a sufficiently strong electric field to prevent mosquitoes from flying between the slats and into the building. Preferably, a voltage of at least 1 kV is applied, which is already in the high-voltage range. For conventionally designed Venetian blinds or Venetian blinds with a slat width of 60 mm to 95 mm and a slat spacing of 55 mm to 85 mm, a voltage between 10 kV and 15 kV appears to be particularly favorable and achieves particularly good results in deterring insects.

[0024] Accordingly, a voltage source is designed that can apply different voltage potentials to the conductors. For example, the voltage source can generate a constant, pulsed, or cyclically increasing / decreasing voltage, so that the electric field is also constant, pulsed, or cyclically increasing / decreasing.

[0025] According to the invention, at least those conductors whose voltage potential differs from ground, i.e., is not zero, are provided with insulation. For conductors whose voltage potential is zero, or for grounded conductors, this precautionary measure is not necessary. In one embodiment, therefore, only the conductors of every second lamination are insulated. In another embodiment, all conductors are insulated.

[0026] The insulation of the conductors according to the invention primarily protects against voltage / current breakdowns, especially in the event of accidental contact between the conductors or laminations. The insulation is also advantageously waterproof, thus providing protection against breakdowns and corrosion even in moisture or rain. When selecting the insulation material used, however, care should be taken to ensure that it attenuates the electric field as little as possible or is as permeable to the electric field as possible.

[0027] Conventional slats often have an additional layer of paint for an attractive appearance. However, it should be noted that while the paint layer of the slats also has a certain insulating and attenuating effect on the electric field, this paint layer is not to be understood as insulation within the meaning of the invention.

[0028] The insulation according to the invention advantageously makes it possible to dispense with other safety measures such as an additional resistor.

[0029] One embodiment provides that the even or odd laminations each have a common conductor that is at a specific voltage potential. Another embodiment provides that each even or odd lamination has its own conductor. Combinations of these are possible. The aforementioned embodiments are not to be understood as limiting.

[0030] To create the electric field between adjacent laminations, the conductors of adjacent laminations are each at different voltage potentials, creating a voltage potential difference. Advantageously, the conductor of every second lamination is subjected to a first voltage potential other than zero, and the conductor of the other laminations is subjected to either a second voltage potential inverse to the first voltage potential or a voltage potential equal to zero. Insulation is advantageously only necessary for conductors that are not grounded or whose voltage potential is not zero. If the voltage potential is zero, i.e., the conductor is grounded, no insulation is necessary.

[0031] According to the invention, the insulated conductor is designed as a high-voltage cable with insulation. In other words, the insulation of the conductor, or the conductors including insulation, is designed as a high-voltage cable. The high-voltage cable, hereinafter referred to as the cable for short, has insulation in the form of a sheath made of plastic, in particular ethylene-propylene polymer (EPR), silicone, or silicone rubber. The cross-section of the conductor is preferably round for better and easier cable routing. Other cross-sectional shapes are also possible, however. The diameter of the cable is advantageously 5 mm to 7 mm or is preferably smaller. With regard to cable routing, the general rule is: the thinner, the better.

[0032] It has proven particularly advantageous to use a common conductor for all even or odd lamellae. For example, the insulated conductor or cable can be routed from an even lamella to an even lamella, skipping the odd lamellae, or vice versa. This advantageously supplies all even or odd lamellae with a uniform voltage potential via a common conductor or cable.

[0033] For example, an insulated cable runs through all even-numbered lamellae and is subjected to a voltage potential of, say, +10 kV. The odd-numbered lamellae can then either be grounded, or another insulated cable can run through the odd-numbered lamellae, which is subjected to a second voltage potential, in this example -10 kV.

[0034] There are various options for routing the cable along the slats. The material of the slats, i.e. whether they are made of a metallic or non-metallic material, is a key factor in choosing the cable routing. If the slats are made of a metallic material, there is the problem that the conductors from the slats are shielded from the conductors in the adjacent slat, preventing the electric field from developing. This can be prevented or circumvented by appropriate cable routing. It is desirable for each conductor or cable to have a clear view of the conductor or cable in the adjacent slat. This is especially true for metallic slats and is at least advantageous for non-metallic slats.

[0035] In a simple embodiment, the high-voltage cable is routed along the longitudinal axis of the slat, preferably in one direction only, so that the beginning and end of the cable are at opposite ends of the slat. For simplicity, the cable preferably runs essentially straight, i.e., parallel to the longitudinal axis of the slat. Of course, the cable can also be routed in curves. This has no effect on the formation of the electric field or the required voltage, but does require more material.

[0036] In another embodiment, the high-voltage cable is guided in at least one loop at least partially along the length of the slat. The cable is advantageously guided in one or two loops. If the cable is laid in a loop, it runs in a first longitudinal direction of the slat, is then laid in a loop for turning and runs back in the opposite longitudinal direction of the slat. The beginning and end of the cable are at one end of the slat. The cable essentially describes a U-shape. It is advantageous to guide the cable over the entire length of the slat if possible. With two loops, the cable is preferably turned again in a loop after being led back, and the end of the cable is then at the opposite end of the slat. The cable essentially describes an S-shape. Other cable routing shapes are also conceivable.

[0037] As already briefly explained, it is particularly disadvantageous with metallic lamellae if the cable's view of the adjacent lamella is shielded by the lamella, preventing the electric field from propagating or shielding it. To circumvent this problem, the simplest approach is to use a non-metallic lamella and / or vary the cable routing, i.e., the position of the cable on the lamella.

[0038] One embodiment of this provides for the high-voltage cable to be routed both on the underside and on the top side of the slat. For example, the cable can be laid in the first direction on the top side of the slat, then loops around to the underside of the slat and is then routed back in the opposite direction. The cable can, for example, be routed around the outside of the short end of the slat or through a hole near the end of the slat. If the cable runs on the underside, it has a clear view of the slat below, possibly with a cable on the top side of this slat. The same applies to the cable on the top side of the slat.

[0039] An alternative embodiment provides for the high-voltage cable to be routed at least partially along the outside of the long edges of the slats. Here, too, the cable is routed in such a way that it always has a clear view of the adjacent slats along the long edge. The electric field is not shielded by the slat material at the long edge.

[0040] Even tilting the slats around their longitudinal axis advantageously does not influence the formation of the electric field in such a, so to speak, free, cable run.

[0041] If the cable is routed along the surface of the slat, it is best secured to the slat. For example, the high-voltage cable can be clipped or glued to the slat. Clipping is advantageous because the position of the cables can be varied as desired using different clips.

[0042] As an alternative to cable routing on the surface of the slats, another embodiment provides for the high-voltage cable to run in a flange on the long edge of the slat. Depending on the material of the slat, the flange shields the cable and prevents the electric field, which is why this simple routing in the flange is particularly suitable for non-metallic slats. If the slat is made of a metallic material, shielding can advantageously be avoided by forming recesses in the flange material. Advantageously, at least 50% of the flange material is left out, so that the cable is securely held in the flange, but the shielding by the remaining material has no significant effect on the electric field. Another advantage of this cable routing is that no separate fastening devices are necessary and the appearance of the slat is not affected.

[0043] The cables are ideally routed so that every second slat is left out. There are also various options for routing and positioning the cables between every second slat. However, the general rule is that the cable length between every second slat should be at least twice the maximum spacing between the slats to avoid hindering the slats from moving up and down.

[0044] It is particularly advantageous and desirable to have the cables run along the guide rails to ensure a visually pleasing appearance of the shading system. Therefore, one design provides for the high-voltage cable to be routed between every second slat in the side guide rail.

[0045] In principle, however, it is also possible to route cables outside the guide rails.

[0046] If the cable is routed in the guide rail, it is also advantageous to guide the high-voltage cable through the guide pin into the guide rail. To prevent the cable in the guide rail from hindering the up and down movement of the slats, the high-voltage cable is preferably twisted spirally at least once between every other slat. This cable routing resembles a spiral-shaped telephone handset cable. It has also proven advantageous if the guide pins through which the cables are routed can rotate around their longitudinal axis or the longitudinal axis of the slat as the slat moves up and down. This means that the guide pin is advantageously mounted so that it can rotate.

[0047] In a second variant of the invention, the insulated conductor is formed as a central, conductive layer in a sandwich-like lamination with outer, non-conductive layers. In this variant of the conductor, the laminations are constructed as a kind of sandwich. The two outer layers are preferably made of a non-conductive, ideally even insulating, material, and the middle, inner layer represents the actual conductor.

[0048] In one embodiment, the conductive layer is a vapor-deposited surface of at least one outer layer. Materials such as copper or aluminum are suitable for vapor deposition. In this variant, the external appearance of the lamellae is advantageously not altered.

[0049] It is also advantageous to have an electrical connection between the conductive layers of each second slat, which is guided through the guide pins and along the guide rail. The electrical connection can be established, for example, using a copper or brass rod, which is guided from the conductive inner layer through the guide pin and is in contact with a busbar in the guide rail. When the slats are moved up and down, the contact between the guide pin and the busbar is advantageously maintained. Another advantage of this design is that the shading device is not visually affected by additional cables.

[0050] A further variant of the invention can also involve forming a type of longitudinal grid in a frame, with the conductors advantageously running in only one direction and spaced parallel. The conductors can be alternately charged with different voltage potentials.

[0051] Such a construction can, for example, be designed as an attachment for a window or a door.

[0052] A further advantageous embodiment of the shading device according to the invention provides for an interface to a building control / automation system. Using the building control or building automation (smart home control), various devices and equipment in a building can be controlled and linked together, for example, venetian blinds, shutters, lighting, etc. For example, the shading device can be automatically switched to an operating state at dusk, so that the electric field for repelling mosquitoes is automatically activated. Furthermore, the shading device can be controlled and programmed to operate depending on the lighting in the building. These are merely examples of possible applications and control options.

[0053] In addition, the invention thus also relates to a building control / automation system for controlling and linking various building devices, at least having at least one interface to a shading device according to the invention as described above.

[0054] Furthermore, the invention also relates to a building, at least comprising at least one shading device according to the invention as described above and at least one building control / automation system according to the invention as described above.

[0055] A particular advantage of the system according to the invention for deterring insects in shading devices is that, in contrast to the system already known from the document EP 3697207 B1, it can be easily retrofitted to existing shading devices.

[0056] In the following, the invention is described in more detail using the preferred embodiments with the aid of the figures, wherein only the features necessary for understanding the invention are shown.

[0057] They show in detail: FIG 1: a schematic bottom view of a lamella with an insulated conductor designed as a high-voltage cable, FIG 2: a schematic longitudinal side view of the lamella according to the Figure 1 , FIG 3: a first schematic cross section through a lamella, FIG 4: a second schematic cross section through a lamella, FIG 5: a schematic representation of a plurality of lamellae with conductors alternately subjected to a voltage potential in a first embodiment, and FIG 6: a schematic representation of the plurality of lamellae with conductors alternately subjected to a voltage potential in a second embodiment.

[0058] The Figure 1shows a schematic bottom view of a lamella 1 with an insulated conductor designed as a high-voltage cable 2. The conductor is subjected to a voltage potential other than zero by a voltage source (not shown here) and therefore has insulation according to the invention. In the embodiment shown here as an example, the insulated conductor is designed as a high-voltage cable 2 or, in short, cable 2. The cable 2 is guided through the guide pin 4 at one end of the lamella 1 and then runs almost the entire length of the lamella 1 until it is looped back in the opposite direction at the other end of the lamella 1. The cable 2 is then guided through the guide pin 4 again. The cable 2 is held by several clip-like cable holders 3, which can be clipped onto the underside of the lamella 1 or into the flange on the long edges of the lamella 1.The position of the cable holders 3 with respect to the longitudinal alignment of the slat 1 can be varied as desired.

[0059] The Figure 2 shows a schematic longitudinal side view of the slat 1 according to the Figure 1 In this embodiment, the cable holders 3 are arranged at equal intervals. The slat 1 has a semicircular cross-section. As a result, both the cable 2 arranged on the underside and the cable holders 3 are virtually invisible from the side.

[0060] The Figures 3 and 4 show different cross sections through a slat 1 with different cable routing. The cable routing according to the Figure 3 corresponds to the cable routing according to the Figure 1 . It can also be seen that the cable holder 3 is clamped or clipped under the flange of the slat 1.

[0061] According to the Figure 4The cable 2 is guided in two loops along the slat 1. The cable holder 3 is designed to hold the cable 2 at three points.

[0062] This cable routing on the underside of the slat 1 is particularly suitable for non-metallic slats 1, since otherwise the conductor would be shielded by the slat 1 and the formation of the electric field would be prevented.

[0063] The cable routing and fastening of the cable to the slat shown here are merely examples and are not to be interpreted as restrictive in any way.

[0064] The Figures 5 and 6Each shows a schematic representation of a plurality of slats 1 with conductors alternately charged with a voltage potential. For better understanding and easier explanation, the slats 1 are numbered from top to bottom. All slats 1 have a conductor 5.0 or 5.1 charged with a voltage, with the voltage value alternating from slat 1 to slat 1, so that a voltage potential difference or voltage difference exists between adjacent conductors 1. This creates an electric field between adjacent slats 1, which covers the intermediate openings and prevents insects from flying through.

[0065] A voltage source 10 is provided to generate the different voltages or the voltage difference. The voltage can be applied, for example, in a constant, pulsed, or cyclically increasing / decreasing manner, so that the electric field is also generated in a constant, pulsed, or continuously increasing / decreasing manner.

[0066] In the embodiment of the Figure 5 The odd-numbered laminations 1a have a common conductor 5.1, which is supplied with a positive voltage, for example, 10 kV, by means of the voltage source 10. According to the invention, the conductor 5.1 is insulated because it is supplied with a voltage other than zero. Here, the conductor 5.1 is designed as an insulated high-voltage cable.

[0067] The routing of the conductor 5.1 along the slats 1a corresponds to the Figure 1The cable routing shown. The conductor 5.1 skips the even slats 1b. The conductor 5.1 is guided through the guide pins into the lateral guide rail, where it is guided between the odd slats 1a (not shown here).

[0068] The lamellae 1a are made of a non-metallic material to prevent the lamellae 1a from shielding the electric field.

[0069] For simplicity, the straight lamellae 1b are made of a metallic material and are connected via the guide pins (not shown here) to a conductor 5.0, which is grounded, i.e., has a voltage potential of zero. According to the invention, insulation is not necessary here.

[0070] Thus, the odd-numbered laminations 1a are arranged alternately with conductors 5.1 carrying a positive voltage, and the even-numbered laminations 1b are arranged alternately with grounded conductors 5.0. A potential difference exists between conductors 5.1 and 5.0, which leads to the generation of the electric field.

[0071] The design of the Figure 6 differs in the cable routing of conductor 5.1 of the odd-numbered slats 1a. Conductor 5.1 is guided in two loops along the length of the slats 1a, so that the beginning and end of conductor 5.1 are guided through the guide pins at the opposite ends of the slats 1a into the guide rail (not shown here). Between the slats 1a, conductor 5.1 thus runs alternately in the left and right guide rails (not shown here).

[0072] Although the invention has been illustrated and described in detail by the preferred embodiment, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by those skilled in the art without departing from the scope of protection of the invention. In particular, the invention is not restricted to the specified combinations of features, but other combinations and sub-combinations that are obvious to those skilled in the art can also be formed from the disclosed features. Thus, embodiments are also to be regarded as encompassed and disclosed by the invention that are not explicitly shown or explained in the figures, but which arise from separate combinations of features from the explained embodiments and can be produced. It is also within the scope of the invention to bring about a mechanical reversal of the functions of the individual mechanical elements of the invention.
