Description

[0001] Title: SWIMMING POOL COVER

[0002] The invention relates to a swimming pool cover comprising support profiles on which a substructure for a covering is arranged, wherein the substructure is formed by several profile elements and has a substructure height.

[0003] The invention further relates to a swimming pool with a swimming pool cover.

[0004] To prevent debris such as leaves or insects, it is common practice to install pool covers around swimming pools, especially in private areas. These are often dome-shaped covers that offer not only advantages, such as allowing swimming on cooler days, but also disadvantages. In particular, these covers take up a relatively large amount of unusable space in the garden, even when designed with collapsible modules.

[0005] Lately, so-called walk-in pool covers have been used more and more frequently. These have a deck that - as the name suggests - can be walked on. There are basically two different types of walk-in pool covers. The first variant is a cover that can be retracted into the pool itself and lowered to the bottom of the pool when not in use. With the second variant, the cover always remains above water and is moved to an area next to the pool when the pool is opened. Both variants have the advantage that the pool cover is available as a usable surface when closed. With the second variant, the surface can also be used when open, e.g. for sun loungers, etc., and this has the additional advantage that objects placed on the pool cover do not have to be removed when the pool is opened.

[0006] DE 30 22 272 A1 discloses a cover for a swimming pool, consisting of a preferably heat-insulating cover plate covering the top of the pool, supported by up-and-down movable columns. Each column is supported by a float that can be lowered below the pool's liquid level by means of a device. The cover plate is reinforced by a girder and provided with a covering on its upper side. The covering rests on a plate resting on a profiled aluminum sheet.

[0007] DE 299 06 689 U 1 describes an insulated lift cover for an outdoor swimming pool, wherein the cover top is made of trapezoidal aluminum sheeting, the top and bottom are stiffened by pressure-impregnated wooden joists, the outer sides consist of a wooden or aluminum frame, and several galvanized or stainless steel square tubes are screwed to the plate, each with wooden joists.

[0008] From CH 630 690 A5 a liquid basin with a cover is known, wherein the cover has at least one outer layer made of sheet metal and at least one inner layer made of plastic, which layers are connected to one another and can be moved as a whole between two end positions, so that in the first end position the cover covers the liquid basin and in the second end position is removed from the liquid basin, and in the first end position the cover rests with its edge region on the basin rim so that a heat-insulating air cushion is created between the inner layer and the basin liquid level. The edge or support edge profile is designed as an end profile which is attached to the outer layer and runs from the outer layer towards the inner layer at a distance from both layers. The outer layer consists of a profiled steel sheet or aluminum sheet that is Sendzimir galvanized on both sides.The inner layer consists of foam panels.

[0009] CZ 15532 Ul describes a roof for outdoor swimming pools with at least one movable panel provided with guide rails guided and fixed on guide elements running along the sides of the pool, the upper part of the panel being designed as a walkable floor.

[0010] Such pool covers typically have relatively large, self-supporting spans, depending on the size of the pool, which is why they must be constructed with correspondingly strong strength. Therefore, known pool covers of the type mentioned above are also relatively heavy. The present invention is based on the object of providing a pool cover with a relatively low or lower weight.

[0011] The object of the invention is achieved with the swimming pool cover mentioned at the outset, in which the profile elements form a plurality of cavities arranged next to one another at a distance, each of which is delimited by a cavity surface, wherein the cavity surfaces are formed by the profile elements.

[0012] Furthermore, the object is achieved with the swimming pool mentioned at the beginning, which has the swimming pool cover according to the invention.

[0013] The advantage of using profile elements with hollow spaces is that they not only meet the structural requirements of the pool cover, but also allow for a reduction in the weight of the pool cover. This weight reduction also enables easier installation and a reduction in the power requirements for drives, etc., making it easier to use photovoltaic elements as an energy source for electric drives. Furthermore, the hollow spaces also offer the possibility of arranging additional elements, such as rechargeable energy storage cells, or as storage space for parasols, etc.

[0014] According to one embodiment of the invention, the profile elements can be formed by sheet metal elements that have a series of sections arranged in a row along the cross-section, wherein the sections comprise or are formed by raised first sections and recessed second sections. This design allows, on the one hand, the raised first sections to provide rear ventilation for the flooring arranged on the substructure, which is particularly advantageous for wooden flooring. On the other hand, the recessed second sections can also provide a drainage option for surface water.

[0015] According to a preferred embodiment of the invention, the sheet metal elements can be formed by trapezoidal sheets. On the one hand, trapezoidal sheets can be easily manufactured in a wide variety of designs, allowing adaptation of the substructure to different conditions or requirements without major technical effort. On the other hand, no further measures are required to provide the aforementioned raised first sections and the recessed second sections.

[0016] According to a further embodiment of the invention, the cavities can be formed by the adjacent arrangement of raised first sections or recessed second sections of sheet metal elements arranged one above the other and connected to each other. For example, the cavities can be easily formed by the mirror-image arrangement of two trapezoidal sheets. In general, this embodiment has the advantage that the size of the swimming pool cover can be more easily changed by cutting the profile elements to the appropriate length, without the need for special parts. The number of identical parts required to manufacture the swimming pool cover can thus be increased.

[0017] According to another embodiment of the invention, for further weight reduction, the raised first sections can be wider in the direction of the cross-section of the sheet metal elements than the recessed second sections. At the same time, this can provide a larger support surface for the covering, allowing greater variability for different covering element dimensions, for example, making it easier to implement an offset joint.

[0018] In order to increase the load-bearing capacity of the swimming pool cover and thus to create larger spans, according to an embodiment variant of the invention, the substructure can have several profile elements arranged one above the other in the direction of the substructure height.

[0019] In this case, or generally, according to one embodiment of the invention, it can be provided that the profile elements form cavities at at least partially different levels with respect to the substructure height. This allows for better load transfer while simultaneously maintaining a lower substructure height.

[0020] According to a further embodiment of the invention, the profile elements can be prestressed in one direction. This makes it possible to at least approximately compensate for the weight load on the substructure caused by the covering, so that the pool cover, once finished, is at least approximately flat. This, in turn, is advantageous both for the drainage of the pool cover and for its mobility, since the profile elements do not bend downwards to the point where depressions are formed in which water collects, and it also prevents tension in a guide system.

[0021] To prevent "cold" from the pool when the pool cover is used in the closed position as a seat, etc., one embodiment of the invention can provide for thermal insulation elements to be arranged below the raised first sections and above the recessed second sections and / or below the substructure. As a side effect, this can also reduce or prevent the cooling of the water in the pool at lower outside temperatures.

[0022] To make it easier to move the swimming pool cover, according to one embodiment of the invention, it can be provided that movement elements for the horizontal displacement of the swimming pool cover are arranged in side areas, in particular on the support profiles.

[0023] According to a further embodiment of the invention, these movement elements are preferably formed by rollers or cylinders.

[0024] For easier installation or to enable the pool cover to be used in areas that are inaccessible by crane, one embodiment of the invention can provide a modular substructure comprising several modules with profile elements. The modules are formed with an overlap in adjacent sections. This overlap provides greater stability to the pool cover at the dividing planes.

[0025] According to a further embodiment of the invention, the support profiles can be designed as L- or U-shaped profiles. This allows for easier connection, especially of prefabricated modules, to a guide system for the swimming pool cover by simply sliding them onto (and in particular connecting them to) the corresponding profile elements.

[0026] According to a further embodiment of the invention, the pool cover can be arranged so that it can be moved without rails, which makes it easier to connect the pool cover to a pool system. In particular, this also prevents the pool cover from tilting when moving between the open and closed positions.

[0027] By using magnetic strips underneath the swimming pool cover, a simple, in particular rail-free, guidance device for the automatic movement of the swimming pool cover can be achieved according to one embodiment of the invention.

[0028] For a better understanding of the invention, it is explained in more detail using the following figures.

[0041] By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations. The disclosures contained throughout the description can be applied analogously to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure, and these positional information must be applied analogously to the new position in the event of a change in position.

[0042] Fig. 1 shows a swimming pool 1 with a basin 2 and a pool cover 3. The basin 2 itself can be designed according to the state of the art, so for further details, reference is made to the relevant prior art.

[0043] In the illustrated and preferred embodiment of the invention, the swimming pool cover 3 can be horizontally displaced between a closed position above the pool 2 and an open position next to the pool 2 (shown in Fig. 1), although intermediate positions are also possible. However, the swimming pool cover 3 can also be designed to be retractable into the pool 2 as a so-called movable floor. In the open position, the swimming pool cover 3 is located at the bottom of the pool 2. It is also conceivable for the swimming pool cover 2 to be moved vertically upwards from the closed position to the open position.

[0044] In the preferred embodiment, the surface area of ​​the pool cover 3 is larger than that of the pool 2 (each viewed from above), so that the pool cover 3 can be arranged to cover the sides of the pool 2. Designed as a movable floor, the pool cover 3 is slightly smaller than the pool so that the pool cover 3 can be lowered to the bottom of the pool 2.

[0045] Fig. 2 shows a section of a first embodiment of the swimming pool cover 3 in an oblique view. The swimming pool cover 3 comprises at least two support profiles 4. The support profiles 4 are arranged in particular in opposite side regions 5, 6 of the swimming pool cover 3, for example along long sides 7, 8 or along wide sides 9, 10 (see Fig. 1) of the swimming pool cover 3. The support profiles 4 or a plurality of support profiles 4 preferably extend continuously and over at least 90%, for example over at least 95% to 100%, of the long sides 7, 8 or the wide sides 9, 10. The support profiles 4 can also form a frame that extends along the long sides 8, 9 and along the wide sides 9, 10.

[0046] The support profiles 4 can be designed as closed profiles or as open profiles. For example, the support profiles 4 can have a quadrangular, e.g., square or rectangular, or a U-shaped or L-shaped, etc., cross-section.

[0047] A substructure 11 (also referred to as a carrier layer) is arranged on the support profiles 4 and connected thereto. The connection between the support profiles 4 and the substructure 11 can be materially bonded and / or force-fitted and / or form-fitted. For example, the support profiles 4 can be received in a groove-shaped recess 12 of the lower housing 11 and / or screwed, riveted, or welded thereto.

[0048] The substructure 11 is designed for the installation of a deck 13 (see Fig. 1). Deck 13 is intended for human traffic. For example, deck 13 can be constructed as a (solid) wood deck, a WPC (wood-plastic composite) deck, or a stone deck.

[0049] The substructure 11 is formed by or consists of a plurality of profile elements 14 and has a substructure height 15. It is provided that the profile elements 14 form a plurality of cavities 17 arranged next to one another at a distance 16. The distance 16 is the smallest distance between the cavities 17. For example, the distance 16 can be between 20 cm and 70 cm. This information serves to clarify and is not necessarily to be understood as limiting the invention. In particular, the cavities 17 extend in the direction of the long sides 7, 8 or the wide sides 8, 9 (see Fig. 1) continuously and uninterruptedly between the end faces or end surfaces of the profile elements 14 and, in particular, the cavities 17 are open at the end faces or end surfaces.

[0050] In the embodiment of the profile elements 14 shown in Fig. 2, the cavities 17 have a circular cross-section. However, the cavities 17 can also have a different cross-section, such as oval or elliptical, quadrangular, e.g. square or rectangular, pentagonal, hexagonal, etc. Furthermore, it is possible for all cavities 17 to have the same shape and size. However, mixed variants of cavities 17 (in the profile elements 14) are also possible. Thus, cavities 17 of different sizes, i.e. with different cross-sections, and / or cavities 17 with different cross-sectional shapes can be arranged or formed (in the profile elements 14).

[0051] The cavities 17 have cavity surfaces 18. In all embodiments of the invention, the cavity surfaces are formed entirely by the profile elements 14.

[0052] In general, the cavities 17 can be arranged parallel to the long sides 7, 8 or parallel to the wide sides 9, 10. Other configurations are possible. Preferably, the cavities 17 also run parallel to each other.

[0053] Fig. 3 shows a section of a variant embodiment of a profile element 14 for the substructure 11 in an oblique view. In this variant embodiment, the profile elements 14, in contrast to the one according to Fig. 2, are not flat, but have or consist of a series of several sections in the course of the cross-section, wherein the sections have raised first sections 19, recessed second sections 20, and transition sections 21 between the raised first sections 19 and the recessed second sections 20. In the variant embodiment according to Fig. 3, the profile elements 14 have, in the direction of the substructure height 15, raised first sections 19, recessed second sections 20, and transition sections 21 lying opposite one another. The cavities 17 are each formed between opposite raised first sections 19.

[0054] The profile elements 14 of the embodiments according to Figs. 2 and 3 can, for example, be designed as continuous cast profiles or extruded profiles, so that the cavities 17 are formed during the production of the profile elements 14.

[0055] Fig. 4 shows a cross-sectional view of a section of another embodiment of the invention. In this embodiment, the profile elements 14 are formed by sheet metal elements 22. In contrast to the embodiments described above, the cavities 17 only arise during the adjacent arrangement of several profile elements 14. In the specific and preferred embodiment, the sheet metal elements 22 are formed by trapezoidal sheets, which are brought into the desired shape, for example, by bending or roll forming. These sheet metal elements 22, in particular the trapezoidal sheets, again have a series of several sections along the cross-section, namely the raised first sections 19, the depressed second sections 20, and the transition sections 21, which in this case have an oblique course with respect to the first and second sections 19, 20.The transition sections 21 may also have a vertical course, although this is not preferred.

[0056] The cavities 17 are created by arranging two sheet metal elements 22, which abut one another in the recessed second sections 20 and are connected to one another in these sections. The two sheet metal elements 22 can be connected by a material fit, for example, by gluing or welding the two sheet metal elements 22 together. Alternatively or additionally, the two sheet metal elements 22 can also be connected to one another in a force-fitting manner, for example, by screwing or riveting. Alternatively or additionally, the two sheet metal elements 22 can also be connected to one another in a form-fitting manner, for example by folding or compression pressing (clinching). In addition to these direct connection options, there is also the possibility of indirectly connecting the sheet metal elements 22 via the covering 13 (Fig. 1), for example by clamping with a U-profile or by lashing with a sheet metal strip, etc.

[0057] As can be seen from Fig. 4, the two sheet metal elements 22 are preferably arranged in a mirror image to one another, so that a mirror plane is formed in the course of the adjacent recessed second sections 20.

[0058] Fig. 4 also shows a variant of the connection of two adjacent units of the substructure 11. The sheet metal elements 22 can end in their side regions with two recessed sections 20. These recessed sections of two adjacent units can subsequently be arranged adjacent to one another and connected to one another. Reference is made to the above explanations regarding the connection options for two sheet metal elements 22. In addition, some of the transition sections 21 can be formed in the side regions of the adjacent units. These transition sections are bent in opposite directions and can come into contact with the respective transition sections 21 of the next unit, as indicated in the right-hand part of Fig. 4. The adjacent units of the substructure 11 can therefore have an overlapping area.

[0059] Figs. 5 and 6 show a further embodiment of the substructure 11 of the swimming pool cover 3 (see Fig. 1), although Fig. 6 only shows a section of it. The substructure 11 has a modular design and comprises two modules 23. More than two modules 23 may also be present. The modular design has the advantage that the substructure 11 can be prefabricated in parts and then more easily assembled on site.

[0060] The modules 23 do not have to be completely identical. Especially with larger pool covers 3, the modules 23 may differ in their edge construction, especially if they are intermediate modules.

[0061] In this embodiment, too, the profile elements 14 or the modules 23 have an overlap area in adjacent sections. The profile elements 14 are again designed as sheet metal elements 22, in particular trapezoidal sheets. As in the embodiment according to Fig. 4, the edge sections can also be designed accordingly here. Alternatively, as shown, it can be provided that the edge sections in the overlap area each form a partial area of ​​a cavity 17, so that in the assembled state a cavity 17 is also formed in these areas. For this purpose, for example, a lower sheet metal element 22 can form an upwardly directed part of a transition section 21 and an upper sheet metal element 22 can form a downwardly directed part of a transition section 21.

[0062] 5 and 6 also show an edge cover 24. The edge cover 24 is also formed from profile elements, in particular made of metal, and serves as a lateral closure of the swimming pool cover 3 or the substructure 11, in particular also for covering the open areas of the cavities 17. For example, the edge cover 24 can have a vertical profile element 25 and a horizontal profile element 26 connected to the vertical profile element 25. The vertical profile element 25 can form the lateral cover, and the horizontal profile element 26 can form the upper cover of the respective module 23 and thus also of the substructure 11. The vertical profile element 25 can also be formed integrally with the horizontal profile element 26. The horizontal profile element 26 and the vertical profile element 25 form, in particular, a groove-shaped receptacle for the profile elements 14 of the substructure 11.

[0063] The vertical profile elements 25 of at least two opposite sides of the swimming pool cover 3 can also comprise the support profiles 4, in particular be formed integrally therewith. For this purpose, the vertical profile element 25 can, for example, have a further horizontal profile section on which the profile elements 14 rest. This further horizontal profile section can, for example, form a groove-shaped receptacle for the profile elements 14 of the substructure 11 with the horizontal profile element 26 (optionally formed integrally with the vertical profile element 25) and the section of the vertical profile element 25 located between these two.

[0064] It should be mentioned at this point that for a better recognition of the shape of the sheet metal elements

[0065] 22, the edge covers 24 on one edge side of the modules 23 are not shown. However, the edge cover(s) 24 are / are preferably present over their entire circumference. The edge covers 24 can also have an overlapping area, wherein, in particular, the horizontal profile element 26 of a module 23 can extend to the immediately adjacent module 23.

[0066] From Figs. 5 and 6 it can be seen that the cavities 17 run at right angles to the support profiles 4.

[0067] Furthermore, it can be seen from Figs. 5 and 6 that, according to one embodiment, the support profiles 4 can have a U-shaped cross-section that is open at the bottom. However, the support profiles 4 can also have a different cross-section, for example, an L-shaped one.

[0068] 5 and 6 further show a variant of the guide of the swimming pool cover 3 for horizontal displacement between the two end positions (open and closed positions). For this purpose, guide rails 27 can be provided in the displacement direction, on which the swimming pool cover is supported. To accommodate or arrange elements for moving the swimming pool cover 3, a receiving profile 28 can be provided between the support profiles 4 and the guide rails 27 (in this variant, at least one guide rail 27 and at least one support profile 4 are present on each of the opposite sides of the swimming pool cover 3). Because the support profiles 4 are open at the bottom, they can be easily slid over the receiving profiles 28, which in turn simplifies the assembly or installation of the swimming pool cover 3 on site.

[0069] If the support profiles 4 and the receiving profiles 28 are dimensioned accordingly, a positive connection can be formed between them.

[0070] From Figs. 5 and 6, it can also be seen that the edge cover 24 can be provided with an apron-like anti-pinch protection 29 or underrun protection on the sides that are perpendicular to the guide rails 27 or generally perpendicular to the direction of movement between the two end positions of the pool cover 3. The anti-pinch protection 29 can be part of the vertical profile element 25, in particular, formed integrally therewith. The anti-pinch protection 29 can be arranged extending only up to the receiving profiles 28, i.e., not across the entire length or width of the pool cover 3.

[0071] Fig. 7 shows a further embodiment of a swimming pool cover 3. Specifically, a module 23 is shown in cross-section. The module 3 again has two sheet metal elements 22 in the form of trapezoidal sheets, arranged in mirror image relation to one another. As in the embodiments described above according to Figs. 4 to 6, the cavities 17 are formed by the adjacent arrangement of recessed second sections 20 of the sheet metal elements 22 arranged one above the other and connected to one another. Alternatively, the cavities 17 can be formed by the adjacent arrangement of raised second sections 19. At least some of the beads formed by the recessed second sections 20 are at least partially, preferably all, filled with thermal insulation elements 30. Furthermore, such thermal insulation elements 30 can be arranged in the cavities 17 themselves. It is also possible to fill the upper beads, ieto provide the recessed second regions of the upper sheet metal element 22, which is located closer to the covering 13 (only indicated), with such thermal insulation elements 30. However, these recessed second sections 20 preferably remain unfilled, since they can be used to drain the swimming pool cover 3 by draining the water on the swimming pool cover 3 via these recessed second sections 20.

[0072] Alternatively or in addition to the described arrangement of thermal insulation elements 30, at least one further thermal insulation element can also be arranged below the substructure 11, i.e. in particular generally below the profile elements 14, in particular over the entire surface of the underside of the substructure 11.

[0073] Alternatively or in addition to the arrangement of the thermal insulation elements 30 and / or the at least one further thermal insulation element, a sealing element, e.g. a sealing lip, can be arranged between the edge cover 24 and the substructure 11 in order to interrupt the air flow path between the interior of the pool 2 (see Fig. 1) and the surroundings of the swimming pool 1. The sealing element or the sealing lip can, for example, be arranged on the support surface of the support profile 4 and the profile elements 14 resting thereon (or the support surface of the edge cover 24 for the profile elements 14). The sealing element or the sealing lip can additionally also form or be an evaporation protection for the water in the pool 2.

[0074] The thermal insulation elements 30 can be formed, for example, from a foam material, such as a polyurethane foam. The foam is preferably at least approximately impact-resistant or pressure-resistant. For example, the foam has a density of at least 40 kg / m 3 Other materials can also be used, such as polystyrene foam, etc.

[0075] In the previously described embodiments of the swimming pool cover 3, all cavities 17 are arranged in the same plane, i.e. at the same height. In order to increase the load-bearing capacity of the swimming pool cover 3 or to form a swimming pool cover 3 with a larger span, however, according to one embodiment it can be provided that the profile elements 14 form cavities 17 at least partially at different planes or heights in relation to the substructure height 15, as is shown in the embodiments shown in Figs. 8 and 9. These embodiments can be produced according to a further embodiment in that the substructure 11 has more than two profile elements 14 arranged one above the other in the direction of the substructure height 15. As with the embodiments corresponding to Figs.In the embodiments described in Figures 4 to 7, one of the levels with cavities 17 is provided by the mirror-image arrangement of two sheet metal elements 22, in particular trapezoidal sheets. If a further sheet metal element 22 is now arranged on the underside of the first cavity level with an orientation similar to the uppermost sheet metal element 22, the embodiment according to Figure 8 is obtained, in which the recessed second sections 20 now also form cavities 17.

[0076] The embodiment according to Fig. 9 is achieved by doubling the first (upper) level with cavities 17, so that a total of four sheet metal elements 22 are arranged one above the other.

[0077] More than four layers of sheet metal elements 22 can also be arranged one above the other, with every second layer preferably being arranged as a mirror image of the immediately preceding layer. In general, all sheet metal elements 22 of a swimming pool cover 3 preferably have the same basic shape, for example, they are all formed as trapezoidal sheets, as can be seen from the illustrated embodiments.

[0078] For example, from Figs. 8 and 9, it can also be seen that the raised first sections 19 can be different in size from the recessed second sections 20. For example, the raised first sections 19 can have a flat first length 31 that is between 120% and 300%, for example between 150% and 200%, of a flat second length 32 (in the same direction as the first flat length 31) of the recessed second sections 20.

[0079] It should also be noted at this point that although the sheet metal elements 22 are preferably trapezoidal sheets, they can also be designed differently, for example wave-shaped with wave crests and wave troughs, if necessary with flattened wave crests.

[0080] The sheet metal elements 22 can have a thickness between 0.7 mm and 3 mm, in particular between 1 mm and 2 mm.

[0081] Furthermore, the sheet metal elements 22 can have a width between 70 cm and 200 cm, for example between 100 cm and 150 cm, and / or a length (parallel to the longitudinal extension of the cavities 17) between 100 cm and 1000 cm, for example between 100 cm and 800 cm. The sheet metal elements 22 can also have dimensions other than those specified.

[0082] The substructure height 15 can be between 10 cm and 60 cm, for example between 20 cm and 40 cm.

[0083] Preferably, the swimming pool cover 3 is formed over the entire area to be covered by a single surface element. However, it can also be provided that this surface element is divided into several surface element parts which can be telescoped into one another when moved into the open position. The sheet metal elements 22 can, for example, consist of steel. Preferably, however, they consist of aluminum or an aluminum alloy or, more generally, of a light metal or a light metal alloy. The profile elements 14, in particular those with a shape like the sheet metal elements 22, can also be formed from a plastic or a synthetic resin / fiber mixture, such as a polyester / mineral fiber mixture (for example with glass fibers or basalt fibers).

[0084] As already explained above, according to one embodiment variant, the swimming pool cover 3 has movement elements 33. The movement elements 33 can in particular be rollers, wheels, or cylinders, as shown in Figs. 10 and 11 for a friction wheel drive. The rollers or wheels are held by the receiving profile 28, which in turn is at least partially received in the support profile 4. Alternatively, the receiving profile 28 or the receiving profiles 28 can also be part of the support profile 4, or the movement elements 33 can be arranged directly on the support profile 4.

[0085] The rollers or wheels are guided on a raised portion of the guide rail 21, which is attached to the floor next to the pool 2 or recessed into it. For this purpose, the rollers or wheels can, for example, have a guide groove into which the raised portion of the guide rail 21 engages. More than one raised portion on the guide rail 21 and more than one groove in the roller or wheel can also be provided.

[0086] As can be seen from this illustration in Fig. 10, the rollers or wheels can also be supported on the support profile 4.

[0087] Generally, the movement elements 33 are arranged either in the area of ​​the long sides 7, 8 or in the area of ​​the wide sides 9, 10 (see Fig. 1). For larger spans of the swimming pool cover 3, at least one further movement element 33, e.g. a roller or a wheel, can also be arranged, e.g. in a central area. This movement element can, for example, only rest on the ground if there is a correspondingly large load on the swimming pool cover 3. If this is not the case, this at least one further movement element 33 can be without contact with the ground. The at least one further movement element 33 therefore has a pure supporting function, which is used as needed.

[0088] Fig. 10 shows a design of the swimming pool cover 3 with cavities 17 arranged at the same height. Fig. 11 shows a design with a substructure 11 corresponding to Fig. 9. To enable a greater substructure height 15, at least one intermediate profile 34 (also referred to as a doubling profile) can be arranged between the support profile 4 and the receiving profile 28. However, for example, the support profile 4 and, if necessary, the receiving profile 28 can also be enlarged accordingly.

[0089] The adjustment of the swimming pool cover 3 between the two end positions (closed and open positions) can also be "guided" in other ways. For example, according to one embodiment, magnetic strips 35 can be arranged on / in the floor, as shown in Fig. 12, by means of which the position of the swimming pool cover 3 can be controlled or monitored during movement or which are used to guide the swimming pool cover 3 during movement. Other guidance options are also possible, such as position measurement, e.g., using IR rays, or sound waves, etc. In general, the horizontal displacement of the swimming pool cover 3 can also take place without rails.

[0090] The adjustment of the swimming pool cover 3 can be motorized. At least one electric motor can be provided for this purpose. To supply the electric motor with electrical energy, at least one photovoltaic element and at least one accumulator can be provided on / in the swimming pool cover 3.

[0091] In this context, it can be advantageous if the movement elements 33 on the side of the swimming pool cover 3 on which the drive element, for example the electric motor, is arranged, are mounted in a fixed bearing, and the remaining movement elements 33 on the other side of the swimming pool cover 3 are mounted in a loose bearing that is axially adjustable in order to be able to compensate for changes in length, etc., and thus to maintain the smooth adjustment of the swimming pool cover 3. According to a further embodiment, which is indicated by dashed lines in Fig. 12, it can be provided that the profile elements 14 are prestressed in one direction. For example, they can be prestressed in a direction perpendicular to the lateral guide elements, as shown. However, they can also be prestressed in a direction orthogonal to this.The preload can be so great that the deflection caused by the covering 13 is compensated.

[0092] The embodiments show or describe possible design variants of the swimming pool 1 or the swimming pool cover 3, whereby it should be noted at this point that combinations of the individual design variants are also possible.

[0093] For the sake of clarity, it should finally be pointed out that in order to better understand the structure of the swimming pool 1 or the swimming pool cover 3, these or their components are not necessarily shown to scale.
