  Technical area: The invention relates to devices for covering basins and in particular swimming pools, in order to protect these basins against external pollution, and provides a function of

  safety against accidental falls for personnel.

  STATE OF THE ART: There are several types of swimming pool covers, each having very specific protection functions: protection against impurities and pollution, against sunlight, against evaporation, against heat loss, for the protection of

personnel at accidental falls.

  The winter cover is opaque to light and protects the basin from external pollution.

  Wile is stretched over the surface of the water and rests on the copings, it is generally made of reinforced PVC. There is a much lighter mesh type variant, but one which is not opaque to light, which facilitates the development of algae in the basin. The summer cover is generally made of a double polyethylene film with air bubbles, and is transparent to light and prevents evaporation while keeping the temperature of the pool. The bar cover is made up of metal bars transverse to the basin which rest on the copings, between which a PVC fabric is stretched. Wile can have winter and summer cover functions, as well as security for small pools. Many patents describe this cover or variants. Mention may be made of the document FR 2637643, or

  EP0465430A1, or also the document EP 057031 lAl.

  The automatic flights are made of PVC blades transverse to the base, semi rigid rolled up and stored in water, and which extend to the surface of the water during

  their use, thanks to a motorization.

  The summer safety blanket (patent EP 0 984 117 A1) when it is made up of the association of a floating polyethylene summer blanket and a safety net

  integral which goes up on the beach to be fixed there.

  Appreciation of the technique Each of these covers provides solutions in relation to the needs, but they

  They also all have drawbacks.

  Regarding the opaque winter cover, it fulfills its function of protecting the water of the basin against external pollution, but it is very sensitive to the weight of snow, and it is very difficult to handle for basins of dimension superior to XlOm because very heavy and bulky. For the net version of the winter blanket, the fact

  that being transparent to light does not protect the basin from the development of argues.

  The bubble summer cover has no protective function for the pond water, moreover

  it is very dangerous if a person falls.

  The cover with transverse bars, fulfills well the functions of protection of the basin against pollution as well as the protection of personnel, but it can only cover small basins (5X10 m) because of a heavy weight and difficult handling . Of

  the more it is very sensitive to bad weather (winds, snow) and of a high price.

  Automatic shutters have no pollution protection function, they are very wind

  dear, sensitive to snow, hail.

  The document EP O 984 117 A1, for its part, describes a bubble but safety summer cover thanks to the association of a safety net. This security summer blanket does

  does not protect the basin against external pollution, but offers personnel safety.

  However, for very large basins, the net-like covering structure becomes quite expensive since the net covers the entire surface of the basin. This technical solution is not optimal in terms of ease of use because of the prohibitive weight of

  ['together, in terms of maneuverability, and in terms of cost.

  Technical problem to be solved The invention solves the problem of having a swimming pool cover which protects the basin from external pollution, from light, which ensures the safety of personnel, and which adapts to all forms of pools while being easy to handle. A specific organization of the covering structure is described in this invention to better take into account the large basins to be protected, which cannot be done by other existing devices.

or already described.

  Disclosure of the Invention: This invention describes a swimming pool cover consisting of a floating structure covering all or part of the surface of the basin and which is associated with a covering structure of the integral net type, the two structures being linked by a device. attachment allowing the separation of the two structures. The invention is characterized in that it is associated with the floating structure which carries it, a structure for protecting the pelvis

  against impurities, comprising in particular a screen film opaque to light and in particular to UV, and one or more screen filters for the filtration of impurities deposited on this

protective structure.

  According to a first embodiment, the protective structure consists of a screen film made of synthetic fabric opaque to light and in particular to UV rays. This film of a few tenths to a few millimeters thick is made of rot-proof and mechanically resistant materials, and will preferably be solid or woven polyethylene treated with UV protection,

  or PVC fabrics, PVC coated polyester, or polypropylene ...

  This protective structure receives on the periphery, and optionally on its interior surface, one or more impurity filters. These wind streams consist of a very fine grid, letting rainwater flow and retaining impurities. The materials of this grid could for example be polyester coated with PVC, polyethylene, polypropylene, etc. In this form of embodiment the filters are either sewn, or welded, or glued to the screen film of the

  protective structure, with which they form a single surface therefore a single product.

  The protective structure is associated with the floating structure in order to protect the water in the basin. To this end, it is carried by the floating structure and fixed to it by a set of means so that the trotting structures: floating, protection, and covering form a body and in particular roll up and unwind together during the setting operations. place and remove the cover on the pelvis. These operations are done for example using a standard market reel. Two types of means are used here

  of assembling structures, between them.

  The first type is a means of assembly between the structural trots allowing their rapid assembly. This assembly device can be constituted, for example, of a set of hooks, eyelets and facets, clips .; .these wind assembly devices preferably arranged

  along the central longitudinal axis common to the trots structures.

  The second type of fastening means consists of a set of means arranged on the periphery of the floating and protective structures and making it possible to link them, so that the protective structure perfectly covers the floating structure, without folds or beads, etc. These means Preferably will be press studs, eyelets with parts or transverse facets for hanging, peripheral hooks The protective structure receives in particular periphery the impurity filters. For maximum efficiency, the protective structure will have the dimensions of the interior of the basin, and the impurity filters will go up along the vertical walls of the basin in order to retain the impurities. This organization of the peripheral filters makes it possible to let the rainwater which has fallen on the protective structure flow, while retaining the impurities deposited also on this structure. For reasons of better buoyancy in

4 2840937

  periphery of the protective structure, it is advantageous to insert a strip of floating fabric between the screen of the protective structure and the peripheral filter. This floating fabric will for example be of the same type as the materials of the floating structure,

bubble polyethylene in particular.

  s According to a second embodiment, the screen film carried by the floating structure, is directly integrated into this floating structure and forms a body with it in a material sense. We therefore have a classic floating structure whose upper face consists of a screen opaque to light. This will be particularly simple to achieve if the materials of the protective structure is the same as that of the floating structure (polyethylene for example), because it is easy to make sandwiches of polyethylene sheets, in particular the upper sheet is opaque to the light and is treated anti W. As in the first embodiment, the filters with peripheral and central impurities are preserved and therefore are fixed to the floating structure. However, the peripheral fixing means are eliminated, since the materials of the protective structure are here directly integrated into the floating structure, therefore these fixing means become useless in this case, both

  floating and protective structures being combined.

  According to a third embodiment, the impurity filters are not attached to the floating structure as in the previous form, but are directly produced by perforating the corresponding zones of this floating structure, in particular on the periphery and

  in the center in certain areas to let the water fall onto the floating structure.

  To achieve this third form, we start from the second embodiment in which the screen film is already integrated into the floating structure, and we realize the multiple perforations 2 5 very fine necessary to realize the impurity filters directly on this floating structure. These perforations will be carried out for example by a mechanical process of perforation with a set of needles or punches, or by thermal processes, or by a scanning laser, ... As in the previous form, the peripheral fixing means do not exist more, only the means of assembling the two remaining structures (

  floating and covering), remain.

  According to a particular way of using the invention, the net-like covering structure is not used. We therefore simply use the floating structure, with which is associated the protective structure produced according to one of the trots described above. In this manner of use, only the peripheral fixing means between the two floating and protective structures remain. In this case of use, the central assembly means between the structural trots are no longer necessary, therefore may not be used,

  or be removed completely if the net protection structure is neither used nor made.

2840937

  For very large basins there is also the association of structured trots: floating, protection, covering, the floating and wind protection structures produced according to one of the trots forms described above. However, the cover structure of the integral net type is not optimum, it will then be produced according to the following organization: the net of the cover structure does not cover the entire surface of the basin, but only a wide strip in periphery covering both the interior periphery of the basin, and the exterior on the beaches. Peripheral straps are available on the outer sides, lengths and widths, and extend 40 to 80 cm from the edges of the pelvis. Some straps will be outside the pelvis and others inside. A peripheral protective net is fixed to these straps, the central inner part of the covering structure therefore does not receive a net. The straps as in the previous case for smaller pools, wind fixed to the beach by suitable studs. Fixing devices

  and of hanging of the structured trots between them also remain identical to the preceding case.

  Likewise, the trots of embodiments of the protective structure are also preserved in the case of large basins fitted with this net covering structure ... perpherque. According to a particular use, it can be associated only with the floating structure and the covering structure with peripheral thread, with the same fixing devices, but the intermediate protective structure is not used. Under these conditions of use, the

  protection of the basin against impurities is not ensured.

  Advantages provided by the invention: Compared with known swimming pool covers, the invention makes it possible to produce, in a single product, a cover for isothermal protection of the basin, for personnel safety, and for protection of the quality of the water against pollution. The invention makes it possible to equip large basins in better conditions of use and maneuverability. Furthermore this

  invention is very easy to manufacture, and at a competitive cost.

  Description of at least one way of carrying out the invention.

  The description of real is ati we give below and the associated sins, wind blown by way of nonlimiting example With reference to drawings 1 and 2 a floating structure (1) covers the surface of a basin . To this floating structure is associated a protective structure (3) which is carried by this floating structure (1), the two structures being linked by compatible assembly means (8) between said floating structures (1) and protective ( 3), as well as a covering structure (2) of the integral net type which covers all of the two structures, and which rises on the outer edges of the basin to which it is fixed. The - protective structure (3) has the shape and internal dimensions of the basin, and is located between

  the two other structures with which it is associated and linked.

  The protective structure (3) consists of: a screen film (4) opaque to light, a screen filter (5) placed on the periphery of the screen film (4), and a set of means for assembly of this protective structure (3) to the

  floating structure (1) and has the covering structure (2).

  The screen film (4) will preferably be made of woven polyethylene, but other synthetic, paired, light-opaque and rot-proof fabrics may be suitable: polyester, PVC, polypropylene ... The screen film (4) is arranged on all of its sides. periphery of a grid filter (5). This filter (5) consists of a strip with a fine grid structure with holes of a few tenths of a millimeter or less. This strip is fixed to the screen film (4) by various methods, of sewing, or by gluing or welding. This strip has a width such that the total dimension of the screen film (4) and its peripheral grid (5) is greater than the interior dimensions of the basin, and therefore therefore the grid filter (5) goes up against the edges vertical pelvis. A height of 3 a

  cm of vertical part of the grid should be sufficient.

  The trots associated structures are linked together by the assembly means (8) which allow their assembly and rapid disassembly. We can use for example a set of eyelets with a tie, snaps or clips. During the operations of placing and removing this composite cover, the trotting structures are maneuvered together and simultaneously using a reel for example. In addition fixing means (9)

  between the floating (1) and protective (3) wind structures arranged at the periphery of the structures.

7 2840937

  These means allow fast fixing and disassembly, for example we will be ceil lets with transverse links, pieces or hooks, or snaps. Their number will be variable, but typically these means (9) will placed every 1 to 3 meters

  on the periphery of structures (1) and (3).

  For large basins shown in Figures 3 and 4, the cover structure (3) does not use an integral net, but is made up of a set of external (22) and internal (23) peripheral straps to the basin ( 21), straps on which a peripheral thread (24) is fixed. The fixing of this net (24) on the straps is done by methods of stitching, bonding, or welding. Structured trots also receive

  means (8) and (9) for fixing and assembling the structures together.
