Abstract

The cleaning system for a surface exposed to weather has reaction surfaces arranged in layers (1.1-1.3). It has metallic surfaces and preferably with a copper content which, in combination with water, develop fungicidal and/or bactericidal compounds which dissolve in water, and which act in cleaning the exposed surfaces. At least two layers are held apart by spacers (2), at least in a part-area, to form zones (14) between them to build up moisture and where rain water can flow in and flush them out. The outer layer has a number of openings (6).

Description

The invention relates to a cleaning device for applying on a surface exposed to the weather, in particular a roof, a roof surface, a solar system surface or a facade, wherein the device has a Has a variety of reaction surfaces arranged in layers are and a metallic, preferably copper-containing, Have surface, which in conjunction with Water-cleaning, preferably fungicidal and / or bactericidal, producing compounds that dissolved in water at least partially wet the roof.

Cleaning devices for roofs and thus for the weather exposed surfaces are well known. Especially Reference is made to the patent DE 100 58 855 C1. This patent describes a roof ridge element Copper, which parallel to the side surfaces of a moisture leading capillary plate which has a capillary gap should generate and thus water, which in one below arranged Blechaufkantung collects, with the help a capillary action between the close-fitting, The capillary gap forming walls sucked upwards shall be.

The problem of this device is that for training such a capillary gap a very accurate production must be present to the capillary action over a Larger region to keep about the same, but the capillary action while ensuring that some water is between the column is sucked in, however, is a flow of Water through the capillary column is not possible because due the surface tension is a feed resistance for the flowing through Water is produced, leaving only an insufficient Water exchange between the capillary gaps and the environment arises, possibly resulting in the formation of substances not sufficiently outward within the capillary gap can occur. Incidentally, have practical experiments with give such closely spaced capillary gaps, that only an insufficient weathering of the material surfaces arises, which reduces the formation of cleansing Ultimately, substances are prevented.

Furthermore, the utility model DE 201 04 999 U1 pointed out. This utility model also discloses a metallic roof ridge element, which preferably is made of copper sheets, with over the length of the roof ridge element is a chamber which is on the bottom by a through Sheet is limited and has a grid on the outside, which achieve a surface-enlarging effect should. Due to the symmetrical design of the Firstelementes will be on both sides of the roof respectively a chamber formed according to that described there The idea of the invention also by a moisture-storing Fleece or braid can be filled. practical Experiments with such a design of a ridge hood have shown that in the thus formed chamber there is no sufficient storage volume, and on top of that the storage time for natural water extremely low is because a much too early evaporation eventual Moisture occurs.

It is therefore an object of the invention to provide a cleaning device for application to a surface exposed to the weather or to find a roof, which is opposite to the one above-described devices improved effect the surface cleaning has.

The inventor has realized that to improve self-cleaning Effect of cleaning devices for application on a surface exposed to the weather it essential is, an optimal combination between the trapped and stored humidity and the available Asked reaction surface of the metal, in particular the Copper, which is necessary, in addition to take care wear is that also a sufficient drainage possibility the liquid stored in the meantime necessary is as soon as a new water supply, so new rain, occurs. It also seems essential that the Embodiment of the cleaning device, in particular the Chambers in which the moisture is recovered, so can be designed that the outside impinging solar radiation the inner chambers are not too much warmed to one early evaporation of moisture from the chambers too avoid.

In addition to the need for adequate water flow it is also necessary by sufficient distance the layers to each other to ensure that the surfaces or reaction surfaces sufficiently in contact with air come to a sufficient weathering of the surface because this condition for the effectiveness of Cleaning device is. Very small distances between the layers in an area where capillary forces between the layers are effective, are unfavorable. It should be distances be elected after a reasonable time, one have sufficient weathering of the surfaces exhibit.

Accordingly, the inventor proposes the per se known Cleaning device for applying to a weather exposed surface, in particular a roof, a roof surface, a solar system surface or a facade, to improve, the cleaning device a variety of reaction surfaces arranged in layers are and a metallic, preferably copper-containing Having surface which cleans in conjunction with water, preferably fungicidal and / or bactericidal compounds generate that dissolved in the water at least the roof can partially wet. According to the invention, the improvement lies in that at least one upper layer, one lower layer Position and at least one intermediate layer are provided, wherein at least two layers at least over a partial area their area separated by spacers are that spaces are formed between the layers in which natural moisture, especially rainwater, tile in and can be rinsed out again.

By this configuration, the occurring water is targeted to multiple levels of moisture through Spacers are formed distributed, with the in these Chambers stored moisture due to the above lying layers, for example, by sunlight relative little is heated, especially if the spacers the neighboring area only touches almost point-like, allowing the stored moisture sufficient time for Is made available with the metallic, preferably latticed surface, to respond and for the cleansing Effect necessary substances from the metallic Surface, which forms the reaction surface to dissolve. In addition, it is ensured by the inventive design, that with newly occurring water one possible unimpeded flushing of these chambers takes place, so that the substances formed there freely to the outside can be washed and on the surface to be cleaned to be effective.

Although it is not absolutely necessary, it can be very be advantageous, at least the outer layer with a variety provided by breakthroughs, so that too on the surface the cleaning device incident rain relative unhindered to the bottom of each layer can penetrate. Accordingly, not only the outer one Location but also the underlying layers and possibly even the lower layer with breakthroughs be provided in order to produce a permeability there, however, the breakthroughs should be sufficiently small should be for easy shooting through of liquid too prevent. So there has to be a compromise between storage effect and obstruction of the flow of fluid be achieved.

To achieve this goal, the individual layers to each other be arranged parallel or conical, wherein it is particularly advantageous if the distance between enlarged the individual layers upwards. Advantageous It is definitely when the area is out of the Sum of the inlet openings is greater than the area of Sum of the outlet openings.

The spacers between the layers can, for example be designed so that they are as punctiform or at most in a line the areas to be kept apart It should be noted that it is the spacers are not necessarily separate Elements must act, but that the layers described can be produced by punching tools and this by appropriate shaping of the surface and optionally Cut out the openings of the spacers integrated into the surface of the individual layers can. The shape of the spacers is here barely set a limit, but it is advantageous if in each case the highest possible increase in the reactive Surface is satisfied by such spacers.

A further embodiment of the cleaning device according to the invention before that at least one below arranged Location for at least one location above it Has bead and / or a hinge, the at least an overlying layer end, preferably at least sections, linear supports. Such Training allows you to overlay several layers wherein the formed beads each arranged above Protect the situation from slipping, respectively if provided between the layers of a hinge is, even a folding of the individual layers allows becomes. Since the cleaning device according to the invention the outer Weather and thus pollution by Dust or deposit of leaves of nearby trees exposed, it may be advantageous to the individual layers take apart or unfold and thus carry out a cleaning in the intermediate areas to be able to. In addition, the possibility arises through a conical opening of the individual layers also a Schneerutschsicherung to produce, once on a sloping Roof lying snow sets in motion, so this one by spreading layers of the cleaning device is slowed down.

The cleaning device according to the invention can be adapted to the most diverse forms of roofs and surfaces, wherein, for example, such a cleaning device can also be designed as a roof ridge or Dachfirstabdeckung. In addition, the contour and / or the surface of the cleaning device can be adapted to the contours and / or surfaces of known roof tiles and roof tiles. With regard to the possible shapes of roof tiles, roof tiles or other roof coverings or surfaces, the website www.braas.de or www.creaton.de is an example. In particular, it should also be noted that the roof cleaning device of the type mentioned can also be used on thatched roofs or roofs that are covered with slate, roofing felt, Welleternitplatten or the like, in particular, an application for solar systems or other glass or Kunststoffbedachungen is possible.

Regarding the number of existing liners has become in the region of Bavaria particularly favorable the number of two Intermediate layers, a total of four layers, However, it may also be sufficient if the cleaning device only one intermediate layer, so a total of three Has layers. To optimize the distance of the individual Layers, it may be advantageous here, the distances of the Single layers not to keep the same, but different to create high spaces, so that as possible optimal water retention depending on the given weather conditions certain regions.

Furthermore, it has proved to be advantageous if at least between two layers, preferably between all If the water entrance slit, i. the gap of the layers, the water flow direction is opposite, larger is considered the water exit slit, i. the gap from the the rainwater when the cleaning device is installed exit; Usually this is the bottom edge of each one Documents.

A further improvement in the effectiveness of the cleaning device can be achieved in that of the The layers formed spaces, copper material with greatly enlarged Surface, preferably granules and / or Flakes and / or braid and / or casings and / or fibers made of copper and / or sintered pieces are arranged. By the Use of such surface enlarging agent is the reaction surface provided greatly expanded, allowing a greater effectiveness of the cleaning device is possible.

The individual layers can be laterally and / or vertically offset be arranged to each other. In addition, the layers can two opposite ends up and / or bends exhibit. The layers can be individually loose or at least the outer and lower layers, preferably all Layers to be interconnected using known joining techniques like screws, nails, rivets, welded joints or adhesive joints are applicable. At least the lower layer, preferably all layers, the three-dimensional Surface shape of roof sections and / or Roof tiles and / or solar systems or other of the weather exposed surfaces are adjusted. For sure Attachment of the cleaning device can at least the lower layer fasteners and / or mounting brackets exhibit. Such fasteners can at least partially made of plastic and in at least one of the layers, preferably the lower layer, clipped be equipped.

A special feature of the spacers can therein exist that this formed braid and / or tissue-like are, so that the layers are resilient to each other Keeping a distance and at the same time as possible low heat fluxes between the individual layers arise.

According to the invention, these layers can be produced in one piece be here preferably by bending and Fold the corresponding spaces are generated.

The individual layers of the cleaning device can on the one hand made of thin sheet metal, preferably copper sheet On the other hand, there is also the possibility at least one layer of the cleaning device by a film, preferably a copper foil to form. If all layers of the cleaning device are formed from films, so this has the advantage that the layers are very simply the outer contour of each covered tile to adjust. In this context, it is pointed out that basically so-called films of thin sheets do not differ. For the purposes of this application but under a slide a largely flexible, itself by own weight at least the large-scale contour a shape of a brick lying under the film, Seen metal surface. Likewise, the framework of the Invention also attributable to a film or layer that made is built up of several layers, not necessarily all Layers must be metallic, but only the The moisture-accessible layer must be metallic Have property to produce the cleaning effect.

An advantageous embodiment of the invention is also therein, the cleaning device with at least one layer, preferably equipped with all layers in the area Elevations and depressions are impressed, preferably This can be done by punching, in particular by rolling rollers. In this context it should also be mentioned that the Production of the cleaning device according to the invention particularly advantageous by at least one punching operation can be.

Alternatively to such a film may also be a braid or tissue can be used as a layer without the scope of To leave invention. In such an embodiment, it is Advantageously, that the loosened structure of a Fabric or braid relative to the projection surface very much large surfaces react with moisture and thus further improves the effectiveness of the device can be.

Additional features and advantages of the invention will be apparent from the following description of preferred embodiments with reference to the drawings and by the claims.

Further variants of roof cleaning devices and spacers.

FIG. 1 shows a cleaning device according to the invention for placing on a roof ridge tile 3. The cleaning device consists of four layers 1.1 - 1.4, which is the Largely embracing roof ridge tiles 3 on the top, Each layer is over both sides of the roof ridge tile extends. The individual layers have this punched Bulges 2 on, as a spacer between the act individual layers. At the bottom of each Layers are bulges 8 bent up, against which each overlying layer can support with its long side. Due to the design of the individual layers with the illustrated Spacers will be sufficient between the layers Rooms 14 generated in the rain or condensation of penetrate above openings 6 in the layers and in can collect the gaps. The layers are like that designed that due to the spacers only a very low thermal contact exists between them, so that too solar radiation does not cause a quick evaporation of lying in the spaces 14 water Leads, giving enough time and surface to training the chemical substances available to the Lead roof cleaning. On the left side of the picture are additionally 14 deposits 7 shown in the interstices, which consist of copper-containing material or copper and in addition to the surfaces of the individual layers cause an increase in the reaction area and also produce a certain water retention effect. Besides, they are on the left side, the breakthroughs are shown in an amplified so that rain easily penetrate the individual layers can.

FIG. 2 shows a similar cleaning device 1 a Dachfirstziegel 3, but here is only the lower Layer 1.4 designed so that it covers the entire roof ridge tile 3, while the further arranged thereon Layers 1.1 - 1.3 arranged exclusively on the side are and by fasteners 5 in the form of screws, Nails, rivets or the like prevented from slipping off become. The design of the individual layers corresponds essentially the representation of Figure 1, wherein also here in addition between the layers deposits, for example Copper grains, casts, sintered elements, braids or the like introduced into the spaces 14 between the layers can be.

FIGS. 3 and 4 show two cleaning devices 1, which are arranged on flat roof tiles 9, wherein these also formed 4-ply. The equipment of the layers corresponds to the figures 1 or 2, again here Intermediate spaces 14 between the individual layers 1.1 - 1.4 are generated in which store moisture can.

In addition, it is shown in FIG the lowest layer 1.4 and the overlying intermediate layer 1.3 a fabric is fed, which in addition a Water retention function and surface enlarging function has, which used insert 7 makes sense should be made of a copper material so that increasingly can form the desired reaction products. It should be noted that it is cheaper, such To accommodate deposits in the lower layers, there Such deposits for an increased heat flow between provide upper and lower layer, but basically undesirable is. However, several are good on the top thermally separated layers already arranged so predominates the preferred effect of water storage and surface enlargement opposite the thermal line.

FIG. 4 shows a variation of the layers with regard to their Spacer in that the first one below Position 1.1 is executed, has spacers 2, which are made of good insulating plastic, so that between the lower layer 1.4 and the overlying Location 1.3 only low thermal contact exists. This will also heat through the underlying Brick as little as possible introduced into the overlying layers. Similarly, the outer layer 1.1 of the underneath lying intermediate layer 1.2 also by clipped, made of plastic spacers separated.

Overall, this creates an optimal combination between Water retention and simultaneous isolation against acting sunlight from the outside. Will from the top Increased water supplied to the cleaning device, so can the previously stored water by those in the deeper Area existing slots or outlet openings 12 of the single layers or between the terminal support points emerge from the layers, thus cleaning the in Flow direction lying roof or other surfaces cause.

The cleaning devices shown in this document represent only selected examples, with the simpler Representation also chosen simple geometric shapes were. On the one hand, this affects the surface the rest of the cleaning devices, as well as the Structure and shape of the spacers, of course different by appropriately trained punch can be executed, with very different Forms can be used. It is advantageous here usually when at least the lower layer of each form the covered surface, especially the underlying Adapts bricks, although it does may be partially advantageous when using spacers opposite the underlying surface to be cleaned is working. The design of the spacers even if formed from the individual layers themselves can be particularly beneficial if they add too much extra Lead surfaces and at the same time as possible a low heat transfer to be kept in the distance Create next location.

It should be noted that in particular, but not exclusively, the embodiments of Figures 1 to 4 are suitable, even by relatively flexible films, in particular copper foils, to be produced since especially films are suitable by forming a surface structure with elevations or dimples despite their flexibility to keep a distance between the layers without that an inherent rigidity would be necessary. Regarding the Using such films, it is also possible individual Make blanks on site and thus informal to adapt to the specifics of each roof.

FIGS. 5a to 5d show cross sections through possible ones Contours of the cleaning device. This is how the contour corresponds FIG. 5a, for example, of a Frankfurt pan, For example, the contour of FIG. 5b may be used be used on a Welleternitdach. Figures 5c and 5d represent simple, slightly curved or flat contours a cleaning device as they are on relative flat surfaces can be used.

Of course, furthermore, all known roof tile contours and contours of all known roof shapes be used.

Figures 6a and 6b show two exemplary outlines of one Roof cleaning device seen from above, the FIGS. 7a to 7c are longitudinal cross-sectional views of the firing direction through the contour of cleaning devices show how they are used for example in the ridge area.

With the figure 8 is a further variant of an inventive Cleaning device are presented, the here on a roof surface with flat flat roof tiles or roof tiles 9 rests. The cleaning device has 4 layers of copper sheet, which are laterally mounted Spacer 2, the layers 1.1 to 1.4 substantially fix in parallel.

The chamfers can be made of plastic, for example, leaving little heat transfer between the layers exists. Rainwater can leak up when running in penetrate the formed openings 6 and is between the Layers 1.1 to 1.4 stored in the spaces 14, where sufficient time to react with the weathered copper surface exists, hence the required chemical reactions can take place. In the end of the cleaning device are by not completely dense clashing the layers formed outlet slots over which the enriched water escape to the surface to be cleaned can. In addition, in this area can also Slits, small openings or perforations in the end area the respective position, preferably in the region of the bead 8 be incorporated to the water outlet as evenly as possible distributed to effect.

The section A-A of FIG. 8 is shown in FIG. Here is particularly good the contour of the exemplary spacers 2 to recognize. These can be one-sided or two-sided for fixing the layers provided with slots be, in which the layers are inserted and thus in their distance be fixed. Alternatively to the shown conical trained slots can also do this in parallel and be formed rectangular.

In the embodiment shown here are the spacers designed so that they are on the surface of the tile 9 lie directly and also the lower layer in one Keep clear of the roof surface for sufficient weathering and to produce the correct metered passage of water. The spacers are here with tabs 10 side attached to or between the roof tiles 9. For fixation between spacer 2 and tab 10 is here-right shown - for example, a fastener 13 in the form of a nail, a screw or a rivet used. As shown on the left, the tab 10 engages a slot in the spacer 2 a. To mention is nor that the length of the individual layers is the same and Therefore, an offset in the longitudinal direction by the width of Bead 8 results.

FIG. 10 shows a cleaning device on a flat roof surface 9 with also 4 layers with lateral Spacer in longitudinal section. However, here are the 3 upper layers laterally completely off the spacers 2 framed, with the layers tapered downwards converge. Through the side facing becomes the water in the rooms formed by the layers especially well restrained. The lower layer 1.1 is essential here longer formed from the remaining layers and so can clamped, for example, with a tile arranged above or become hooked.

Furthermore, the illustration shown can also only be used as one-sided part of a symmetrical ridge element considered, in which the lower layer 1.1 the Roof ridge covers or even forms itself.

It should also be noted that this type of execution, when mounted in lower areas of a roof is particularly well suited as a snow brake or at least this function additionally takes over. Also combinations from parallel and conically arranged layers are possible.

FIG. 11 shows a 3D representation for a better view with wire model of the roof cleaning device from Figure 8, while the figure 12 is a 3D representation of Roof cleaning device of Figure 10 shows.

In the figure 13 is a cross section through a roof cleaning device similar to the figures 8 or 10, but with shown differently executed layers. Left is the lower layer without openings with an overlying one Sintered insert shown. Above it is a fine perforated layer 1.2, above a coarser perforated layer 1.3 followed by the one with big holes or slots 6 openwork upper layer 1.4. In addition, there is between two layers an elastic connecting element 11 - here with Spring elements - arranged, which a elements - arranged, which a slipping apart of the Spacer 2 prevents and thus helps the layers safely to jam. It should be noted that the position and number of connecting elements can be varied can.

The right side of Figure 13 shows another arrangement the layers 1.1 to 1.4. Here the upper layer 1.4 is closed trained, underneath is a strong structured uniformly thick sintered surface 1.3, followed from a sintered layer 1.2, which is formed centrally thicker is considered marginal, again followed by a strongly perforated one lower layer 1.1.

It should be noted that due to different climatic conditions also the optimal arrangement of individual layers varies, with usually the goal of the arrangement is, as long as possible water storage paired with good weathering conditions and good drainage reach the generated reaction products.

According to the invention, the cleaning device of a flat copper material to be punched, pointing out is that under punching all manufacturing processes too understand that fall under this term - see for example DIN 9870 or "Die Werkzeugbau", 1997, ISBN 3-8085-1202-4, in particular chapter 1 "punching technique". FIG. 14 shows an example of such a cleaning device in longitudinal section, by multiple Abandoned and wrinkles produced 4 perforated layers. shown is a side of a ridge element that is symmetrical arranged opposite side is not shown in the picture. Of course, this type of design and Production also for other types of cleaning device used, for example, for similar configurations as in the previous figures.

A specific variant is shown in FIG a cleaning device 1 of 3 V-shaped folded and mated layers, of which perforated 2 layers are formed. As spacers act here the above-arranged bends, each on the support the lower layer and thus the distance and alignment determine the positions.

Figure 16 shows a longitudinal section through a simple folded roof cleaning device 1, which is a kind of bag forms, in which an intermediate layer 1.3 with integrated spacers 2 is inserted. The liner is in the bottom Inserted into a groove area, here also as Spacer 2 is used. Additionally, they are located below in the folded bag forming the layers 1.1 and 1.3 small outlets 6, which store the stored liquid after appropriate reaction time and nachdrängendem new Drain rainwater.

FIG. 17 again shows a variant of a cleaning device on a flat roof surface with 4 layers 1.1 to 1.4 with lateral spacers 2 in longitudinal section. For better fixation of the layers 1.2 to 1.4 are on each side two spacers attached, which themselves into the lower Location 1.1 are clipped. The lower layer 1.1 is through the ends of the holder 2 at a distance to the underlying Surface is held and is arranged with the above Tiles against slipping hooked.

A roof ridge element used as a roof cleaning device is designed and basically of its construction the cleaning device of FIG. 16 corresponds to FIG of Figure 18 shown in 3D representation as a wire model. These curved surfaces are also very easy and cost-effectively by punching method.

Figures 19 and 21 show further exemplary embodiments the cleaning device according to the invention in particular to the variety of forms and execution of the spacers 2. Thus, Figure 19 shows a cleaning device similar to Figure 17, but here are the individual layers 1.x not the same length, but shorten from the bottom Position 1.1 up to the upper layer 1.4. This will achieve that in moderately to slightly occurring rain all Interspaces 14 between the layers even without openings in the surface of the layers are filled with moisture. This applies to both stable layers of sheet metal as well as layers made of flexible foil. In addition, a variation of Spacer 2 shown. These consist of one Combination of spacers 2.2 and one through the Spacer rings performed connecting element 2.1. For example can as spacers simple washers, Rings or wedges made of various materials like plastic, rubber or metal are taken.

Be as shown in Figure 19, on one side the same used high spacing elements, one obtains a parallel Location distance. FIG. 20 shows how by different height spacers a conical Course of the layers 1.x can be reached.

For simplicity, it is shown in FIG correspondingly wide contact surface of the spacer elements 2.2 also sufficient to install only one spacer 2 per side, to achieve a sufficient fixation of the layers. The same is also in the figure 22 for a non-parallel course of the layers 1.x shown. additionally is here at the lower duck of the lower layer 1.1 still one - shown in chiselled - flanging or bevel 15 shown into which the upper layers can be inserted, to achieve additional fixation.

The last figure 23 finally shows a further inventive Device in which by means of a punching process from the surface of the layers 1.2-1.4 integrated spacer elements 2.2 are withdrawn and not anymore must be used individually. In the resulting open space the spacer elements a centering element 2.3 is inserted, at the same time as a kind of washer serves for the connection element 2.1. This can for example be made of plastic, or too designed as a metal sleeve with washer lying on top be. Basically, there are a large number of different distance-maintaining connection possibilities of individual layers, all of which are within the scope of the invention.

Overall, it should be noted that all shown and all cleaning devices according to the invention both just as well as wavy or curved, both longitudinally as well as be formed in the transverse direction without the To leave frame of the invention. In addition will be added noted that all in the embodiments shown positions also with elevations and depressions and / or openings may be provided without the frame of the To leave invention.

With regard to the stamping process mentioned in the application It should be noted that this includes all manufacturing processes to be understood in the DIN 9870, Sheet 1, issue Oct. 1974, including there in the Alphabetic overview cited further DIN sheets with possibly further references.

Overall, therefore, by the illustrated invention a Cleaning device disclosed which is suitable due to the most favorable moisture storage and at the same time strong enlargement of the reaction surface under different climatic conditions cleaning surfaces exposed to the weather cause. In this regard, it should be pointed out that such cleaning devices are not exclusive can serve for cleaning roofs, but in addition also clean other weathered surfaces, For example, this may be solar systems, Glass fronts, glass roofs or building facades act.
