    TECHNICAL AREA
    The present invention relates to a cover according to the preamble of claim 1.
    STATE OF THE ART
    Various systems are known from the prior art, which are based on the task of protecting a pool from environmental influences. There are inflatable pool covers, hereinafter referred to as covers for short, which protect a pool from dirt, snow and rain, especially in winter. These covers contain a double tarpaulin, which is why they are heavier than simple covers. Such a cover is not suitable for every pool, especially not when the water level is low, which is particularly the case in winter when it is drained under the skimmer for frost protection reasons. These covers are also not suitable if the pool is to be completely emptied and still protected from all kinds of dirt.
    Inflatable covers, which consist of two sheet-like materials connected to one another at the edge or near the edge, for example by gluing or a weld seam, advantageously fabric-reinforced tarpaulins and at least one closable opening, hereinafter referred to as a valve, for introducing a filling medium such as air , can weigh between 30 and 100 kg, depending on its size. This makes it difficult to apply such a cover to a pool. Due to its own weight, this cover can sink at least partially when it is placed on the water, so that water can get onto the surface of the cover and it can only be moved with great effort.
    This type of cover is often on eg eyelets, which are often attached at a distance of 50 to 80 cm at the edge of the tarpaulin, attached to the edge of the pool, for example via a rubber cord, which is expensive, so that this is usually only as a pure winter cover is used, which is a disadvantage.
    If the cover is fixed with water on its surface, for example at the pool edge or outside the pool edge, this must first be pumped out before the cover is inflated with air. If the cover is inflated with water on the surface, the grommets may tear off because the load may become high depending on the amount of water. Another disadvantage is that these covers can rest and chafe on the edge of the pool, which is often made of rough material such as flagstones. This can damage the tarpaulin, which can cause the cover to leak. When such a leak occurs, it is also troublesome to find that leak across the surface, especially when it is a large cover.
    There are simple covers to which pipes are attached to the surface. These have the advantage that they can be easily applied to the pool. The fact that the cover sags between the pipes and water can collect there is disadvantageous. Holes are often made on the cover so that the water can drain off. Another problem is that rainwater can run off into the pool and contaminate the pool water. Also dirt deposits such as leaves can collect on the cover, which can clog the holes or have to be removed again before rolling up, which is difficult especially with larger covers, since it is not easy to get to the spots, especially in the middle of the cover . This type of covers also does not have a great insulating function as the simple covers tend to be thin. The pipes to which these covers are attached are usually oversized so that they sag as little as possible, which can make the covers heavy.
    Inflatable covers are also known with tubes provided at their edge, which have the task of anchoring the tarpaulin to the edge of the pool.
    Roller shutter covers, which represent a good and easy-to-use cover for a pool, are complex in terms of technology, often expensive and the rainwater runs into the pool.
    PRESENTATION OF THE INVENTION
    The present invention has for its object to provide a cover that eliminates the aforementioned disadvantages and makes it possible to easily apply this to a pool without the surface of the covers fills with rainwater, for example, and even when the water level is lower used and where water cannot run into the pool.
    According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous refinements and developments of the cover according to the invention are specified in the dependent subclaims.
    According to the invention, a cover of the type mentioned is characterized in that at least one air- or gas-filled chamber has a curvature pointing upwards when filled with air or gas, and the at least one chamber has at least one bulge aligned in the longitudinal or transverse direction of the cover, continuous tubular or strut-like strut is assigned, which rests on both sides of the pool edge and stabilizes at least one chamber.
    Ideally, depending on the size of the pool, several struts aligned in parallel at defined intervals are provided.
    The struts are advantageously formed from a rigid or (bending) elastic material, such as aluminum or fiberglass.
    The attachment of the struts can preferably be done in that they are attached to the edge of the cover. In an advantageous embodiment of the invention, the struts are fastened to the cover with preferably flexible material, ideally a rubber cord, via holes at the ends of the struts and via eyelets that are integrated on the edge of the cover. However, the strut ends can also be designed in such a way that they are provided, for example, with a recess and, for example, with edge protection. The struts can also be fastened in that a tunnel-like receiving profile, which can be designed continuously or in segments, can run through the struts and be attached to at least one of the sides of the cover. Ideally, several such mounting profiles are attached so that the cover can rest well on them.
    The cover can also be connected to the struts by a flexible and / or elastic band, belt or rope-like connecting means such as a belt, ratchet strap or elastic rope on the opposite side of the cover is connected to the strut ends, whereby the cover is caught between the struts and the lanyard after it has been inflated.
    In addition, the cover can be attached via eyelets, which are advantageously mounted immediately next to the strut on both sides in the edge of the tarpaulin, preferably via an elastic connecting means, which keeps the cover on tension and the struts together. The advantage of an elastic connection means is that flexibility is achieved and the tension of the cover can be adjusted.
    However, the connecting means can also be guided through the strut, fed back on the opposite side of the cover and lashed down using, for example, the tensioner of the connecting means or, for example, the lashing strap. This fastening with connecting means also has the advantage that the ends of the receiving profile are not heavily strained when the cover is inflated if the cover bulges and the struts remain rigid. By having the connecting means on the opposite side of the cover
    parallel to the struts, the tarpaulin does not need to be fully inflated, which is beneficial as the cover is kept flat, making it quicker to deploy. It is also an advantage that the cover becomes plump and has a firmness similar to that of an air mattress, which gives it good stability.
    Due to the recess on the top of the cover by the connecting means, the water runs off better, since the cover is more taut and so quickly no troughs can form, for example, rainwater.
    The cover can easily be rolled up and rolled up by the struts that rest on the edge of the pool without water getting onto the surface of the cover. Also, no contamination can get into the pool when the cover is rolled up.
    The cover bulges when inflated, which means that the struts can also be made thinner, since it does not matter if they sag slightly down, since the water can also carry the cover. Especially in pools that are filled to the brim with water, the struts do not need to be large or can also be made of flat material, for example, since they only have to take over the function of rolling up.
    The struts can have various shapes, such as round, rectangular or square, but also flat or crescent-shaped. It is also possible to replace the solid material with inflatable poles, which are used in tent construction. The strength of the material can also be achieved by additionally attaching a tubular film-like material to one side of the cover, for example by welding or gluing, and providing it with at least one additional valve in order to inflate the resulting chamber with air to such an extent that it becomes rigid and tightens the cover. The air escapes from the cover when the valve is opened. By rolling it up, which is preferably made possible by the struts, it can escape more quickly, which is an advantage.
    This inflatable stiffener can also be completely attached, for example, close to the edge of the cover, which simplifies the application of the cover, especially for round pools, since it slides through the air of the stiffener on the water surface without water getting onto the surface of the cover . Once secured, the chamber can be deflated and the cover inflated at the same time.
    The cover can also be connected to the struts, for example, by inserting them into openings with approximately the diameter of the struts on both sides of the tarpaulin edge, which can be non-inflatable behind the weld and e.g. 15 cm wide. Due to the fact that the cover is inflated, the edge in the area between the struts is pressed down in addition to gravity, so that in this area between the parallel struts only the outer edge of the cover rests on the edge of the pool, which has the advantage that no dirt and, for example, no small animals can get into the pool between the struts.
    It also has the advantage that the inflatable part of the cover is protected, since it cannot chafe on the edge of the pool, which is important with this type of cover. Eyelets can also be attached to this edge to additionally secure the cover to the edge of the pool. With this variant it is also possible to use the cover on e.g. a round pool or pools with a tube frame, which are often offered today. The struts rest on the edge and the edge of the tarpaulin, which does not have to be inflatable, can be pulled down outside the pool and also fastened. The opening does not necessarily have to be round like a hole, but can also be designed, for example, by an elongated slot or as an oval or rectangular opening on the edge of the cover, which is open to the edge. The eyelets on both sides of the opening make it possible for them to nestle tightly against the strut by pulling the lanyard. The opening can be covered by an overlap with e.g. a tarpaulin over the edge of the tarpaulin so that no water can get in there.
    The struts, which can be plugged or telescopically extendable for easier, cheaper transport through at least one pipe division, for example, can be held together with the connecting means that runs on the opposite side of the cover by the connecting means, for example, with hooks or attached to a fastener at the end of the strut and strapped down.
    The struts, if they are plugged into one another or pulled out telescopically, can also be locked, for example, with a screw and the associated nut.
    It is also conceivable that the struts are connected, for example, with a thinner, precisely fitting strut in the area where the struts collide, so that further attachment by screws, for example, does not have to be carried out, since the strut pieces between the strut ends tighten of the tension belt are pushed together and thus held together.
    The inner strut can also be limited in the insertion depth by having the diameter of the outer strut in the central area, e.g. over a length of 5 mm. It is also possible to make the inner brace a little thicker by e.g. squeezing in the middle area so that it gets stuck when the braces are pushed together.
    But are also conceivable caps that can be made of different materials, such as preferably made of plastic, which can be plugged onto or into the strut ends and have, for example, a recess for guiding the connecting means or can have at least one hole , through which the lanyard can be passed.
    The struts can also be designed flat at the respective ends, whereby the cover lies flat on these ends and the edge of the pool.
    It can be attached to the edge of the cover and a kind of bags, in principle, as the struts of a parasol are attached to the edge of the umbrella fabric, in which the struts are inserted. In order to attach the telescoping struts there, for example, they can be locked firmly after insertion into the pockets or a spring can be fitted in the struts, which pushes the strut ends into the pockets and thus firmly connects them to the cover, with the spring being flexible the tension of the cover may react when inflated.
    After at least the two outer struts, which are connected to the cover, or the cover directly via, for example, eyelets on the example, preferably four outer corners, on round or differently shaped covers the four opposite sides, with a band, cable or belt-like material such as a belt, for example, has been attached to ground hooks outside the pool and the cover has been inflated via the valve, rainwater can run off upwards over the edge of the pool through the resulting bulge.
    Instead of the outer struts on the transverse sides, for example, eyelets can also be attached there, since these struts on the edge do not have a supporting function.
    The attachment of the cover can also be done, for example, directly on the struts or on the cover via eyelets on the eg long sides at the edge of the cover via a fixed connection or with a flexible material such as preferably rubber cord by this outside of the pool is attached.
    Since the cover rests above the water surface at the height of the pool edge, it does not have to be inflated far because it does not have to rest on the lower water surface. The water still runs off over the slight curvature over the edge of the pool. It doesn't matter how low the water level is.
    The pool is also well protected from heat loss by the air cushion, since the cover, which is clamped between the brace and the connecting means and does not have to be inflated as much, circulates less, resulting in good thermal insulation. Another advantage of this type of cover is that even if the cover were to leak, it still provides some protection because the struts keep the cover
    protection will not perish. Without struts, so much water would collect in depressions on the cover, especially in the winter months when the cover is not permanently monitored, that it could be difficult to pull it out of the water. Then depressions could form on the cover due to the load of e.g. snow or rainwater, which could at least partially undermine it and the water level would rise with the clean swimming pool water and some of this would run off over the edge of the pool or over the skimmer.
    The struts can also be attached above the cover with loops, for example. In this case, the cover itself can be larger or longer than the struts, so that it hangs down over the edge of free-standing pools and can be attached there with e.g. In this variant, no holes would have to be made in the edge of the tarpaulin to enable laying. When this cover variant is inflated, it is pressed onto the edge of the pool and closes with it. If the water level is high, the cover will rest at least partially on the water. If the air is extracted, the cover contracts and can be rolled up. In this variant, too, the connecting means could be attached to the underside of the cover, which means that the cover would not protrude deep into the pool when the water level is low.
    Because the cover can rest on the water in this variant, the struts are bent at least slightly upwards by inflating the cover, so that the water can run off along the struts over the edge of the pool.
    The struts can be made thinner and lighter because they only serve the purpose of rolling up the cover in this case or when the water level reaches the edge of the pool. The advantage here is also for large, e.g. public, swimming pools, which are often filled to the brim, as the cover can be easily rolled up on the edge and on the water surface.
    The cover can also be divided into at least two, advantageously several, chambers, e.g. between the parallel struts. Ideally, the connections between the upper and lower tarpaulins would be in the area of the struts and the individual chambers would each have at least one valve through which the air could be blown in and out. This has the advantage that in the event of a leak, a defect only has to be located on part of the surface of the cover, which greatly simplifies the search and is particularly advantageous for larger covers, since it is almost impossible to find such damage on one to find a large area. Even with such a solution, no water would form between the chambers, but would run off above the connection and the struts along the upper tarpaulin over the edge of the pool. It is also conceivable to connect the individual chambers, e.g. via valves or an air duct, which would make inflation easier.
    The struts can also be attached directly in the middle under the respective chambers, which means that they then have to be inflated even less.
    It is possible for the individual chambers to be connected to one another via a detachable connection such as an ideally watertight zip fastener, which makes it possible to replace the individual chambers without great effort in the event of damage. However, other detachable connections such as a Velcro fastener or eyelets that are held together with a rope are also conceivable.
    This variant would have the advantage that the individual chambers could be commercially available, for example, as standard items, which would enable rapid replacement. It is also an advantage that when ordering such covers with different standard widths, e.g. in an online shop, a customer can put the cover together himself, since the lengths result from the number of chambers. This has the advantage that the covers do not have to be custom-made for each individual pool, which would usually be more expensive and could lead to longer delivery times. In the event of a defect must also
    not the whole cover has to be handed over to the dealer for repair, for example, only one chamber has to be replaced or repaired.
    The divisible variant only works in conjunction with the strut, since this ensures, at least when the water level is low, that the connection runs above the edge of the pool, so that the rainwater can run off over it. This variant will also simplify application, e.g. in public swimming pools, since the individual chambers can be more easily transported to the swimming pool, assembled on site and applied to the swimming pool.
    It would also be conceivable to have at least two fixed connections of the upper and lower tarpaulin running parallel next to each other, e.g. at a distance of 10 cm. These connections would be inexpensive to make as it is just another connection such as a weld that makes it possible to sever and remove a defective chamber between the two connections without damaging the individual intact chambers. This gives you the option of adding a new chamber, e.g. by gluing.
    A further variant consists in that struts are attached above and below the cover, whereby the cover, when the parallel struts are connected to one another at the strut ends, is clamped and does not have to be fastened further. As a result, the cover can also carry a higher load due to the double number of struts, which can be an advantage in snowy areas and particularly useful when the water level is lower.
    A few more advantages of the cover are explained below, such as that with a few standard dimensions all possible shapes of pools can be covered, such as rectangular with Roman steps, oval, kidney-shaped or round pools if they are embedded in the ground and the Cover can rest on the edge of the pool. The shape of the cover can also be adapted to any conceivable shape of the pool.
    Also, this stiffened cover can be placed on a pool without attachment, at least for the time when there is no strong wind blowing. Protection against dirt and rainwater and the insulating function are guaranteed.
    It is also possible to place the rolled-up cover on the edge of the pool and inflate it, causing it to unroll itself. Due to the rigidity, it is possible to lift the complete cover from the pool with e.g. two people without letting the air out. It is also possible to roll up only part of the cover or to open part of the cover when it is full, e.g. to take a water quality measurement or to cool down briefly.
    According to the invention, the cover itself can be made of various flexible materials, such as transparent material, in order to utilize the solar thermal effect.
    Since this cover is associated with only a small amount of additional work and costs, e.g. with regard to the struts and connecting means, or the additional fixed, inflatable chambers, this type of pool cover will also be used in summer and will find a wide audience.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Other goals, features, advantages and possible uses of the cover according to the invention result from the following description of exemplary embodiments with reference to the drawings. All of the features described and/or illustrated form the subject matter of the invention, either alone or in any combination, regardless of the summary in individual claims or their back-reference.

    CARRYING OUT THE INVENTION
    As can be seen from FIG. 1, the inflatable cover 1 comprises at least one air- or gas-filled chamber 14, which has a bulge pointing upwards in the air- or gas-filled state. At the chamber 14 several in the longitudinal or transverse direction of the cover 1 spaced and aligned parallel, continuous tubular or strut-like struts 2 are assigned, which lie on both sides of the pool edge 10 and stabilizes at least one chamber 14. The connections of the upper 6 and lower tarpaulin 7 are in this case attached in the region of the struts 2 and the individual chambers 14 are each provided with at least one valve 13 through which the air can be blown in and out.
    In FIG. 2 it can be seen how the inflatable cover, called cover 1 for short, is connected to the strut 2 by a connecting means 3 . The connecting means 3, ideally a bungee cord, is pulled and tensioned by an attachment, for example a hole 15 in the strut end 21 and lugs 12, for example, which are attached behind the weld seam 5 in the tarpaulin edge 17, which is non-inflatable, so that the strut 2 protrudes through the opening 20 in the tarpaulin edge 17 and this rests on the edge 10 of the pool. The opening can also be designed as a hole in any shape.
    Fig. 3 shows how the cover 1 is additionally held with a connecting means 3, which runs over the upper tarpaulin 6. The receiving profile 22 can also be seen on the left side, which is connected to the cover 1 by two connections on the receiving profile 16 . In this recording profile 22 is the strut 2, which is designed to be divisible by a pipe division 9 and whose pipe sections can be plugged into one another. This strut 2 is attached via an attachment 4 to the edge of the pool 10 or outside of it.
    Fig. 4 shows a variant in which the struts 2 are attached to the upper tarpaulin 6 of the cover 1. The struts 2 lead through tunnels 22 which are attached to the upper side of the upper tarpaulin 6 continuously or in segments, for example by loops. As a result, no belt 3 is required since the lower tarpaulin 7 rests on the water surface 11 in this case. In this variant, the cover 1 can also be easily applied to the pool by unrolling it and attached directly to the pipe ends outside of the pool. Because the struts 2 bend slightly upwards, rainwater can run off easily. As a result, the struts 2 do not have to be dimensioned so strongly, since they have no load-bearing function but only take on the task of stabilizing the cover 1 for rolling up.
    The receiving profiles 22 can also obtain their rigidity in that they are hermetically sealed via connections 16 on the receiving profile 22 and provided with a valve 13 . This makes it possible to slide the cover with the inflated reception profiles 22 on the water surface 11 to the other side of the pool without sinking, which simplifies the application of the cover 1, especially in large swimming pools.
    5 shows a variant in which the cover 1 consists of a plurality of chambers 14 which can be replaced by a detachable connection 8, such as an ideally watertight zip fastener. The individual chambers 14 are connected by the zip fastener by pulling it shut. The struts 2 ideally run under
    71717
    the detachable connections 8, whereby the rainwater can drain over the pool edge 17 via the depressions forming between the chambers 14.
    shows in detail a chamber 14 with the inflatable tunnel 22 and the detachable connection 8. Through the valve 13, the receiving profile 22 and the chambers 14 can be filled with air and emptied. The individual chambers 14 can be connected with the detachable connection 8 .
    The design of the cover 1 according to the invention is not limited to the preferred embodiments given above. Rather, a large number of design variations are conceivable which make use of the solution shown even with a fundamentally different design.
