Definitions

  • the invention relates to a cover device for a swimming pool, comprising an inflatable cover and a roll-up and roll-down device onto which the cover can be rolled up and unrolled when not inflated.
  • the invention also relates to a swimming pool with such a covering device
  • Such a swimming pool cover is described in DE 3000396 A1 and DE 2354279 A1.
  • the inflatable swimming pool cover described in these publications is in the form of an air-filled mat which, when inflated, lies on the water surface and essentially covers the entire water surface.
  • the cover can be rolled up onto a roller located at the edge of the pool, with the air in the cover being forced out through an open valve at the end of the cover by means of a spring-mounted counter roller or counter plate. A suction of the air can support this process.
  • the cover If the cover is now to be brought onto the water surface, compressed air is blown through the valve located at the free end. Then the part of the cover that is in front of the roller and the counter-roller fills with compressed air. The compressed air creates a force that pulls the cover out of the retractor by itself, pushing it across the water surface when inflated.
  • the design of the swimming pool cover as an inflatable body has the advantage of being easy to handle, requiring little space when rolled up and good thermal insulation.
  • traditional inflatable pool covers lack stability. In order to guarantee the inflatable capability, the cover must be made of a flexible material so that, even when inflated, the cover yields under load, similar to an air mattress. Conventional designs of inflatable swimming pool covers are therefore not walkable.
  • the present invention therefore aims to increase the stability of a swimming pool cover without losing the advantages of an inflatable cover mentioned above.
  • the invention essentially provides for an inflatable cover device for a swimming pool of the type mentioned at the outset that the inflatable cover is formed by an inflatable body that is plate-like when inflated, the top and bottom layers of which are made of a flexible material and a multiplicity of connecting threads or fibers are connected to one another and, in the inflated state, are kept at a maximum normal distance from one another.
  • the required dimensional stability and rigidity of the inflatable cover is achieved in that the top and bottom layers are connected to one another by a large number of connecting threads or fibers and are kept at a maximum normal distance from one another in the inflated state.
  • the top and bottom layers are in this case of the Threads or fibers are preferably held parallel to one another, so that a plate-shaped body is actually formed.
  • the threads or fibers run through the air-filled cavity of the body and extend between the top and bottom layers, preferably in a direction perpendicular to the layers.
  • the fibers or threads are provided here in such a density that the top and bottom layers each form a substantially flat surface when inflated, so that the overpressure prevailing inside the body does not cause any bulges.
  • the fibers or threads are preferably distributed evenly over the surface of the top or bottom layer.
  • an increase in stability is achieved in that the connecting threads or fibers are interwoven.
  • Inflatable hollow bodies whose top and bottom surfaces are connected to one another by interwoven threads or fibers are also referred to as drop-stitch constructions, which are mainly used for water sports equipment, namely so-called Stand Up Paddling (SUP) boards.
  • SUP Stand Up Paddling
  • the principle of the drop-stitch construction is based on linking the top and bottom layers of the body with vertical connecting fibers and keeping them in the desired shape even under high internal pressure.
  • the interwoven fibers form the inside of the inflatable body a fabric that is very tear-resistant and dimensionally stable due to the large number of knots and can withstand particularly high loads, but can still be rolled up compactly when not inflated.
  • the swimming pool cover Due to the high rigidity of the swimming pool cover according to the invention, it can be walked on without further ado and can be used as a play or sunbathing area. This allows the area of a garden occupied by the pool to be put to good use when the pool is not in use due to seasonal or other reasons.
  • the thickness of the cover is preferably 5-30cm, especially 10-20cm. This results in an extremely high load-bearing capacity of the cover, which is 100kg/m 2 per 10cm thickness.
  • the cover In order to prevent the cover from moving back and forth on the water surface in the swimming pool, the cover is preferably supported on all sides on the edge of the pool or on another stationary structure. This usually means that the dimensions of the cover in the width and length direction essentially correspond to the extent of the water surface or the cover extends to the edge of the pool or a maximum gap of max. 50mm, preferably max. 30mm, remains.
  • max. 50mm preferably max. 30mm
  • the problem arises that the cover drags along the edges of the swimming pool, which is due to the existing between the cover and the edge of the pool Friction can lead to an obstruction of the ejection process. For example, the danger of jamming or wedging of the cover between opposing pool edges.
  • the top and/or bottom layer is provided with means for changing the width of the covering extending transversely to the up or down direction and/or the width in the up or down direction.
  • Unwinding extending length of the cover is provided.
  • a reduction in width means that the cover is at a distance from the respective lateral pool edge on both sides when it is pushed out onto the water surface.
  • the width reduction can be reversed so that the cover rests against the edge of the pool on both sides and is then clamped firmly between the edges.
  • the clamping is released again by bringing about a width reduction and the cover can be rolled up again effortlessly.
  • the means for changing are designed in such a way that the width or length when the cover is rolled up is reduced compared to when it is fully inflated.
  • the means for changing are preferably designed so that they can be actuated pneumatically.
  • the change in width or length can be caused by inflation or deflation.
  • the pneumatic actuation can be provided in such a way that the width or length increases as soon as a certain air pressure is exceeded inside the cover during inflation.
  • a Width or length reduction is generated as soon as the air pressure inside the cover falls below a certain level.
  • the means for changing are attached to the top and / or bottom layer of the cover, so that for a width reduction of the cover, for example, a shortening of the width of the top or bottom layer or for a length reduction of the cover, for example, a shortening of the length of the Top or bottom layer can lead.
  • the width or length of the top or bottom layer can be shortened by subjecting the top or bottom layer to folding or another change in shape, in which the top or bottom layer is bent at least at one point along its width. or longitudinal extension is deflected from its planar configuration.
  • the means for changing can be attached both to the top layer and to the bottom layer.
  • the means of modification may be attached to either the top sheet or the bottom sheet. If only one of the two layers experiences a shortening of the width or length extension, this leads to an angled shape of the cover, which leads to a width or length reduction of the cover. If both layers experience a shortening of the width or length extent, the covering as a whole remains flat with the formation of a width or length reduction or a zig-zag configuration results depending on the positioning of the changing means.
  • the means for changing the width or length have at least one Material strip which is only connected to the top and/or bottom layer in its widthwise or lengthwise opposite edge areas and can be shortened or warped in a central area between the edge areas to reduce the width or length of the cover.
  • the strip of material can extend over at least 80%, preferably over at least 90%, in particular over 100% of the length of the cover.
  • the strip of material is preferably elastic in the middle area, with the top or bottom layer forming a fold under the middle area when the cover is not inflated.
  • the top or bottom layer is pulled together by the force acting to reduce the width or length of the central region, so that a fold is formed, which leads to a reduction in the width or length of the respective layer.
  • the air pressure building up inside the cover gradually counteracts the force exerted by the elastic midsection until that force is sufficient to maximally stretch the elastic midsection .
  • the material strip is materially bonded to the top or bottom layer in its edge areas and a closed chamber is formed between the material strip and the top or bottom layer, with a valve for filling the chamber with air and for emptying it or air connection is provided.
  • the closed chamber can be filled with air, whereby the chamber assumes a tubular shape, which bulges the top or bottom layer accordingly, as long as the pressure inside the cover is lower than in the closed chamber.
  • the bulged area of the top or bottom layer returns to the flat shape, whereby the cover takes up its full width or length.
  • the valve or air connection for inflating the closed chamber can be arranged at the free end of the cover or at the end connected to the winding and unwinding device.
  • the valve or the air connection is preferably connected to an air hose which, if the valve or the air connection is arranged at the free end of the cover, is rolled up together with the cover onto the winding and unwinding device or unwound from it.
  • the air hose can preferably be designed as a pressure-resistant hose.
  • the strip of material extends along the center of the width or length of the bottom or top layer.
  • a strip of material may also be placed at the free end of the cover to define a closed chamber as described above which, when inflated, assumes a tubular shape with the tubular axis extending transversely to the roll-up and roll-down direction.
  • a closed chamber at the free end of the cover can be used in the inflated state as a floating body when the cover is pushed out in order to prevent the cover from sinking.
  • At the end of The closed chamber can be emptied again during the ejection process, which leads to an increase in length in order to press the cover against the edge of the pool.
  • any other floating body can be provided at the free end of the cover without having the above-described function of changing the length.
