Description

Title of the invention: POOL ENCLOSURE MODULE technical field

[0001] The invention relates to a module of a swimming pool enclosure, such an enclosure and an installation comprising a swimming pool and such an enclosure. Previous art

[0002] For the safety of persons, the NF P-90309 standard requires that a pool enclosure, in the position of covering the pool basin, does not present any passage between the outside and the inside of the enclosure allowing the entry of a body with a diameter of more than 100 mm.

[0003] Covering the pond is also useful to limit energy losses and protect the pond from soiling by leaves, pine needles, pollen and other pests, especially in "wintering" mode.

[0004] For private swimming pools, the shelter is generally a "low" shelter, that is to say, having a maximum height, measured from the ground around the pool on which it rests, of less than 1.8 m.

[0005] A low-profile pool enclosure, particularly a telescopic low-profile enclosure, is typically made up of a set of modules that the user can move by rolling them along the pool, from the storage position to the position where they cover the pool. Such an enclosure is described, for example, in EP 2 098 661.

[0006] The shape of a module is adapted to evacuate rainwater laterally, i.e., towards the longer sides of the basin. To promote ventilation and prevent excessively high temperatures under the shelter, selectively closable openings may be provided on the top of the module.

[0007] There is a continuing need to further reduce the environmental impact of swimming pools.

[0008] One object of the invention is to meet, at least partially, this need. Summary of the invention

[0009] The invention proposes a module for a swimming pool enclosure, said module having a height of less than 1.8 m and comprising: - a framework formed by an assembly of crossbeams and hoops, and - at least one infill plate rigidly fixed to said framework, the framework and said at least one infill plate together defining a roof shaped to guide rainwater falling on said roof towards at least one crossbeam on the periphery of the module, or "edge crossbeam".

[0010] The module includes a drain comprising: - a gutter placed in the roof at a horizontal distance from said edge cross member of between 10 cm and 100 cm, the gutter having a bottom through which is at least one drainage orifice to divert, by gravity, said rainwater under the module; - a movable shutter between open and closed positions in which access to said at least one rainwater drainage orifice is opened and closed, respectively; - optionally, a removable filter arranged to filter rainwater before it flows through said at least one drainage orifice.

[0011] As will be seen in more detail later in the description, the drain allows: - to collect a large quantity of rainwater which, classically, flows onto the terrace surrounding the basin; - to drain this rainwater towards the basin, and thus reduce the need for mains water supply.

[0012] The drain is also accessible to a user, who can in particular open or close the shutter, depending on the water level in the basin or the desired ventilation.

[0013] This results in a substantial reduction in domestic water consumption, in particular for topping up the water in the pool, and thus a reduction in the environmental impact of the swimming pool.

[0014] This horizontal distance can be smaller the smaller the module. In particular for the smallest module of the shelter, that is to say for the module whose edge crossbars are closest to the edge of the pool in the covering position, it can be less than 50 cm, preferably less than 40 cm, or even less than 30 cm.

[0015] A module according to the invention may further include one or more of the following optional and preferred features: - the shutter is a flap, which is advantageously technically simple; - the module includes a hinge for pivoting the shutter, preferably extending along a longitudinal edge of the chute; - the hinge extends along the lower longitudinal edge of the gutter, the lower longitudinal edge of the gutter being the longitudinal edge of the gutter on the side of said edge cross member, which makes it possible to form an obstacle to the flow of water immediately downstream of the gutter; - the hinge extends along the entire length of the chute, which allows it to form a continuous barrier; - the maximum opening angle of said shutter is greater than 100°, which makes the open position of the shutter stable under the effect of gravity or a push from rainwater overflowing from the gutter; - the flap and / or the hinge are shaped so as to form a barrier, preferably along the entire length of the flap, opposing the flow downstream, i.e. towards said edge cross member, of rainwater overflowing out of the gutter; - said at least one drainage opening is - pierced in said base, the base preferably being traversed by several drainage holes distributed, preferably regularly distributed, along the gutter, the gutter then preferably being defined by a single crossbar; or - defined by the shape and / or spacing of two crossbeams extending side-by-side, preferably to define a slot; - the gutter is formed in a horizontal profiled cross member and the bottom of the gutter is only crossed by an evacuation orifice at one or each of its ends; in other words, the bottom of the gutter is solid, except at least one of the ends of said cross member, pierced with said evacuation orifice; - the ends of the crossbar(s) defining the chute are preferably rigidly fixed on respective hoops, preferably without protruding below said hoops; - at least one, preferably each drainage outlet is defined by a conduit, preferably straight, preferably vertical, with a height greater than 3 mm, so as to reduce the cone of rainwater flow at the outlet of said conduit; - in the open position, the shutter protrudes less than 50 mm from the surface of the roof surrounding it, which allows the module to be nested when the shelter is telescopic; - the chute is formed by at least one horizontal profiled cross member defining a groove in which a peripheral edge of said at least one filling plate is housed - said at least one filling plate is made of polycarbonate and is preferably cellular, the cells preferably forming straight and parallel channels; - two filling plates each have a peripheral edge housed in a respective groove formed in a cross member or in an assembly of cross members forming the chute.

[0016] Further research has also led to improvements in the filter.

[0017] Preferably, the filter comprises or consists of: - a grid; and / or - a textile, woven or non-woven; and / or - a foam.

[0018] Preferably, the filter: - is shaped to prevent direct flow of rainwater under the module, i.e., to force rainwater to follow a meandering path through the filter; and / or - is shaped so as to be hand-compactable from a resting configuration, reversibly, the return to the resting configuration preferably being elastic; and / or - comprises a filtration material made of a polymer or cellulosic material; and / or - preferably comprises a reactive material that chemically interacts with the rainwater passing through the filter, preferably to inject a product capable of modifying its pH and / or a bactericidal product; and / or - includes a filter base and rims extending from the filter base.

[0019] The invention also relates to an installation comprising: - a swimming pool comprising a basin and a terrace bordering the basin; and - a shelter configurable in storage and covering positions in which the shelter permits and prohibits access to the pool for a user, respectively, said shelter comprising a plurality of modules, at least one module, preferably each module, with a height of less than 1.8 m and comprising: - a framework formed by an assembly of crossbeams and arches, and - at least one infill plate rigidly fixed to said frame, the frame and said at least one infill plate together defining a roof shaped to guide rainwater falling on said roof towards at least one cross member around the perimeter of the module, or "edge cross member".

[0020] The module includes a drain comprising: - a gutter placed in the roof and having a bottom through which at least one drainage opening is passed to divert, in said covering position, said rainwater so that it enters the basin less than 50 cm from the edge of the basin; - a movable shutter between open and closed positions in which access to said at least one rainwater drainage orifice is opened and closed, respectively; - optionally, a filter, for example a removable filter grid, arranged to filter rainwater before it flows out through said at least one drainage orifice.

[0021] Preferably, the shelter is telescopic, the modules being nested one inside the other, in a nesting fashion, in the storage position and being mobile in translation along the pool, preferably by means of wheels, up to the covering position in which they form a cover over the pool.

[0022] Preferably, said module, preferably each module is a module according to the invention.

[0023] Preferably, the installation includes rails, preferably straight, fixed to the ground, guiding the wheels of the modules.

[0024] The invention further relates to a cross member for a pool enclosure module, the cross member comprising a profile shaped to receive a filling plate, for example made of polycarbonate, said profile defining, at least partially, the channel of said drain.

[0025] Preferably, the profile defines two grooves shaped to receive each the edge of a filling plate, the two filling plates being coplanar or not. Brief description of the figures

[0027] In the various figures, identical references are used to designate identical or similar parts. Definitions

[0028] For the sake of clarity, and unless otherwise indicated, "horizontal" and "vertical", "upper" and "lower", "above" and "below", "top" and "bottom", refer to a position in which a module is placed on a horizontal surface, in the overlapping position. The same applies to "height", measured along the vertical direction.

[0029] By "horizontal distance" is meant a distance measured on a view of a module or shelter when the module or shelter is observed from above, i.e. along a vertical observation direction.

[0030] Unless otherwise indicated, "right" and "left", and "lateral" are assessed by considering the direction of movement X of a module, between the storage and recovery positions.

[0031] The "lateral" edges of a module or shelter are the right and left edges of said module or shelter, by which the module or shelter rests on the ground, preferably by means of wheels.

[0032] The equivalent diameter of an orifice is the diameter of a disk with the same surface area as the opening of said orifice.

[0033] Unless otherwise indicated, "fix" implies a rigid fixing.

[0034] “Contain” or “include” or “present” should be interpreted as in a non-exhaustive manner. Detailed description

[0035] An installation according to the invention comprises a swimming pool 4 and a shelter 6. Pool

[0036] The swimming pool 4 comprises a basin 12 and a terrace 14 formed around the basin. The basin typically includes a staircase, not shown, for the user to access it. The terrace may include a coping stone delimiting the edge 17 of the basin. The coping stone is typically 25 to 35 cm wide and 2 to 5 cm high, measured from the terrace floor.

[0037] The basin 12 contains a liquid, classically water, optionally heated by a heating device, such as a heat pump.

[0038] The basin is generally rectangular in shape, viewed from above.

[0039] The length of the pool is classically greater than 5 m, 6 m or 7 m and / or less than 15 m, 12 m, or 10 m. The width of the pool is classically greater than 2 m, 3 m or 4 m and / or less than 10 m, 7 m, or 5 m. Shelter

[0040] Different types of low shelter are known.

[0041] A low shelter can be telescopic, the modules fitting together like nesting boxes to be stored, in the storage position, next to the pool, which reduces the footprint. The dimensions of the modules are adjusted so that a push, according to the direction of movement, on the largest module gradually pulls the other modules along, as the shelter unfolds to the overlapping position.

[0042] A low shelter can be raised, each module being raised by tilting around one of its edge crossbeams.

[0043] The enclosure 6 is a low-profile enclosure typically composed of sub-assemblies, often called "modules" 20, or "elements," which, in the overlapping position, are placed end to end to form, with the pool, a tunnel closed at each end by a gable end 21, or "front." In the overlapping position, the assembly of modules 20 thus forms a cover over the pool. The shape of the modules, and the possible presence of seals 23, make it possible to reduce, or even eliminate, air passages between two adjacent modules. The enclosure thus limits heat exchange between the water in the pool and the external environment. It therefore contributes to maintaining the water temperature and, in particular, to energy savings. It also contributes to water cleanliness by limiting the entry of impurities into the pool (leaves, sand, soil, etc.).

[0044] The dimensions of the modules are adapted to those of the basin, so as to cover it completely in the covered position, protruding as little as possible from the basin, to limit the bulk.

[0045] Figure 1 illustrates an example of a telescopic pool enclosure 6 consisting of six modules 20 dimensioned so that they can be stored, at least partially, one under the other in the storage position, leaving free access to the pool for a bather to enter, and so that they can be deployed to cover the entire pool in the retracted position. Figure 1 illustrates the operation of storing the enclosure 6.

[0046] A module, preferably each module can be removable and / or sliding, according to the direction of movement X. In a sliding or removable shelter, the modules can be stacked on top of each other in the storage position.

[0047] As shown in [Fig. 3], each module 20 comprises a roof 22, and optionally one or more side walls 24 extending substantially vertically from the roof to the ground. To drain rainwater towards the right edge beams 40d and left edge beams 40g, the roof may comprise a horizontal section, or, preferably, a roof slope, two sloping roof slopes connected along a ridge 26, or even more than two slopes, in a so-called "multifaceted" configuration. Alternatively, the roof may be curved, for example, in a cross-sectional plane perpendicular to the direction of travel, in the shape of an arc, for example, a circular arc.

[0048] Each module of a low shelter preferably has a height h20, measured from the ground around the basin on which it rests, of less than 1.8 m, 1.5 m, 1.0 m or 0.5 m.

[0049] The modules which, in the overlapping position, are at the ends of the shelter each define a gable, vertical or inclined, preferably defined by one or more infill plates.

[0050] Regardless of the type of shelter, a module 20 classically comprises a frame 30, and a "filling" consisting of one or more filling plates 32 rigidly fixed to the frame.

[0051] The frame 30 is an assembly of bars and classically carries a set of wheels, not visible in the figures, configured so that the module can be moved along the direction of movement X, preferably by the push of a user alone, between the covering and storage positions, preferably exclusively along the direction of movement.

[0052] The wheels roll on the ground or in rails fixed to the ground, to the right and possibly also to the left of the module, when moving the module from the storage position to the covering position.

[0053] The bars are preferably profiles, preferably hollow, preferably tubular. They are typically made of aluminum or sometimes of wood or resin. Aluminum is advantageous for its lightness, mechanical strength, and resistance to UV radiation, weathering, and the oxidizing atmosphere of the swimming pool.

[0054] For clarity and by convention, a bar extending in a plane perpendicular to the direction of movement is called an "arch," and a bar connecting two arches, preferably extending parallel to the direction of movement, is called a "crossbar." A crossbar is preferably horizontal.

[0055] An arch can be curved, preferably curved, or straight.

[0056] The bars define an edge frame, preferably rectangular seen from above, made up of the assembly of hoops 38, in particular of two front edge hoops 38f and rear edge hoops 38b, and crossbars 40, and in particular of two edge crossbars, or "edges", right 40d and left 40g.

[0057] Each edge hoop preferably has a length, measured perpendicular to the direction of movement X, of between 2.5 m and 7 m.

[0058] Each edge cross member preferably has a length, measured along the direction of movement X, of between 1 m and 3 m, classically of 2.1 m or less.

[0059] The surface delimited by the edge frame can be partitioned, in particular by means of one or more intermediate crossbars 40i and, in a less preferred embodiment, by one or more intermediate hoops. View from Above, the framework defines a grid, delimiting one or more openings. Each opening is thus framed by an elementary frame formed by the framework. Each opening is completely closed by means of a respective infill plate 32, preferably closed by means of an infill plate 32 whose peripheral edge 33 is housed in a corresponding groove 35, preferably defined by the profile of the bars forming the elementary frame ([Fig. 4]). All means of rigidly fixing the infill plate to the framework are considered.

[0060] Reinforcing bars 37, preferably parallel to the crossbeams, can also be arranged under the infill panel and support it. A reinforcing bar stiffens the frame and supports an infill panel. However, it does not immobilize this infill panel "laterally," that is, it does not prevent movement of this panel within the plane of the panel, unlike the crossbeams and hoops.

[0061] The filling plate is most often made of polycarbonate, plexiglass or glass. It can be solid or partitioned.

[0062] It is preferably thermally insulating, which allows, when covered, the heat from solar radiation to be stored under the shelter. This results in gains of 6°C to 8°C in water temperature, depending on the region and the pool's exposure.

[0063] The filling plate 32 is preferably made of polycarbonate. Advantageously, unlike polystyrene or foam, polycarbonate is essentially free of pores that could retain water, and thus generate hygiene problems (mold, odors, etc.).

[0064] The filler plate 32 is preferably made of cellular polycarbonate, the cells preferably forming straight and parallel channels. Advantageously, such a filler plate is highly insulating.

[0065] Preferably, and in particular when the filling plate is perforated, the filling plate has: - a thickness greater than 2 mm, preferably greater than 5 mm, and / or less than 32 mm, preferably less than 16 mm, preferably less than 12 mm, preferably less than 10 mm, and / or - a length greater than 1 m and / or less than 10 m, and / or - a width, measured along the direction of movement X, greater than 0.5 m, preferably greater than 0.8 m, preferably greater than 1.0 m, preferably greater than 1.1 m and / or less than 2.5 m.

[0066] In one embodiment, particularly when the filling plate is solid, i.e., without cavities, the filling plate has a thickness greater than 2 mm, and / or less than 10 mm, preferably less than 5 mm, preferably less than 4 mm.

[0067] The above characteristics preferably apply to each filling plate.

[0068] Preferably, a filler plate, preferably each filler plate extends over more than 80%, preferably more than 90%, or more than 95% of a cross member of the module.

[0069] The frame may, for example, include one, two, three, or four intermediate cross members 40i. In one embodiment, the frame does not include an intermediate cross member, that is, it only includes a right-hand edge cross member and a left-hand edge cross member. The infill panels thus extend substantially over the entire width of the module, measured perpendicular to the direction of movement X. Lateral drainage of rainwater is thereby improved.

[0070] Preferably, the module includes one or more reinforcement bars under one or more filler plates, to support it / them.

[0071] The set of filling plates forms the "filling", or an "insulating layer".

[0072] The upper insulating layer is shaped to ensure rapid drainage of rain to the outside, preferably towards the edge rails. In the preferred embodiment, the upper insulating layer is curved outwards, preferably exclusively towards the edge rails.

[0073] Advantageously, the insulating layer and the frame together form, in the covering position and in the closed position of the shutter, a substantially airtight barrier between the basin and the external environment, in particular opposing the circulation of air between the roof of the basin and the external environment. Drain

[0074] According to the invention, module 20, preferably each module, comprises a drain 41 ([Fig.4]) comprising: - a gutter 42 shaped to divert said rainwater under the roof of the module; - a shutter 44, preferably attached to the gutter, movable between open and closed positions in which access under the module, by rainwater running from the ridge of the roof, is open and closed, respectively.

[0075] The drain is positioned in the roof of the module so as to: - be accessible to the user without the user having to use a tool or climb onto the module; - be as low as possible to collect as much rainwater as possible running off the roof, while allowing the collected water to drain into the basin.

[0076] The drain is preferably positioned in the first two meters, preferably in the first 1.5 meters, preferably in the first meter of the roof of the module, starting from an edge cross member and following the shape of the roof.

[0077] The drain 41 is preferably disposed at a horizontal distance d4i between 10 cm and 100 cm, preferably greater than 20 cm and / or less than 80 cm, preferably less than 60 cm, preferably less than 50 cm from an edge cross member 40d / 40g, the distance being measured on a top view of the module.

[0078] As illustrated in [Fig.2], the drain 41 is preferably arranged so that, in the covering position, the collected rainwater falls at a horizontal distance d[7 less than 50 cm, preferably less than 40 cm, preferably less than 30 cm, preferably less than 20 cm, preferably less than 10 cm, and / or more than 2 cm, preferably more than 5 cm from the edge 17 of the basin.

[0079] The drain 41 preferably extends horizontally.

[0080] The length of the drain 41 is preferably greater than 80%, greater than 90%, and preferably substantially equal to 100% of the distance between the hoops between which the drain extends. The length of the drain is preferably greater than 1 m, preferably greater than 1.5 m, preferably greater than 2 m and / or less than 3 m, and preferably less than 2.5 m. Preferably, the drain extends between the two edge hoops of the module.

[0081] The drain preferably extends in a horizontal plane.

[0082] In one embodiment, the module frame comprises two edge hoops 38b / 38f, preferably forming hoops connecting the two edge cross members 40d / 40g, and the drain, preferably integrated into an intermediate cross member 40i, connects these two edge hoops.

[0083] The chute 42 preferably has a profiled shape, for example with a U-shaped or V-shaped cross-section. The chute 42 is preferably closed at its ends by cheeks or, preferably, as illustrated in [Fig.5], by the hoops 38 between which it extends, which limits the escape of water through these ends.

[0084] Preferably, as shown in [Fig. 5], the drain does not protrude below the hoops between which it extends. In other words, the distance h between the bottom of the drain and the bottom of any of said hoops ([Fig. 5]) is greater than or equal to 0 mm, preferably greater than 5 mm.

[0085] The chute 42 preferably has: - a width 142 greater than 0.5 cm, preferably greater than 1.0 cm, preferably greater than 2.0 cm, preferably greater than 3.0 cm, preferably greater than 3.5 cm, and / or less than 10 cm, preferably less than 7 cm, preferably less than 5 cm, and / or - a depth p42 greater than 0.5 cm, preferably greater than 1 cm, preferably greater than 1.5 cm, preferably greater than 2.0 cm, and / or less than 10 cm, preferably less than 5 cm, preferably less than 3 cm.

[0086] The shape of the gutter 42 advantageously allows for the temporary storage of rainwater before it flows, by gravity, into the basin. The drain thus remains effective even in the event of downpours.

[0087] In one embodiment, the channel is defined by the shape of one or more intermediate cross members 40i, preferably profiled. The profile of the intermediate cross member(s) defines not only the channel, but also at least one, preferably two grooves 35 in which respective infill plates, for example made of polycarbonate, polymethyl methacrylate, or glass, are housed. Preferably, the infill plate is rebated and jointed along its entire length.

[0088] The filling plates can also be housed in grooves 57 ([Fig.5]) formed in the arches and extending in the same plane as the grooves 35.

[0089] The gutter 42 is shaped to guide the rainwater it receives towards the basin. For this purpose, the bottom 43 of the gutter is traversed by one or more drainage orifices 54.

[0090] In one embodiment, the bottom of the gutter is traversed by more than 10, preferably more than 50, preferably more than 100, preferably more than 200, preferably more than 300 drainage openings per linear meter of drain. Rainwater thus flows rapidly, by gravity, into the basin.

[0091] In one embodiment, the bottom of the chute is crossed by less than 10, preferably less than 5, preferably less than 3 drainage orifices 54.

[0092] In one embodiment, the drainage opening(s) is / are located exclusively at the ends of the chute, the bottom of the chute being therefore solid and only traversed by drainage openings at one or each of its ends. This reduces manufacturing costs. Furthermore, the filter can be of reduced dimensions. In particular, it may consist of one or more strainers or small grids that extend only to the ends of the chute and are advantageously easy to clean.

[0093] In a preferred embodiment illustrated in [Fig. 4], the chute is formed by assembling two intermediate cross members 40i' and 40i”, preferably profiled. The profiles preferably have a general L-shape. The first arms of the L are locally substantially perpendicular to the plane of the infill panels, preferably forming substantially flat walls. The second arms of the L are substantially perpendicular to the first arms and oriented towards each other, the free edges of the second arms preferably being parallel to each other. to the other, and spaced apart to form a drainage opening 54 in the form of a slot that preferably extends along the entire length of the drain. Preferably, the second branches form ledges 55 on which a filter, for example a grid 56 or foam, is placed. Preferably, each of the two cross members has a groove 35, or "rebate," in which a respective filler plate is housed. This embodiment is advantageously inexpensive, particularly because it is not necessary to drill holes to create the drainage openings.

[0094] Furthermore, in one embodiment, the position of the intermediate cross members 40i, which include a drain, along the hoops, can be modified before they are rigidly fixed to these hoops. The width d54 ([Fig. 5]) of the slot-shaped drainage opening can be easily modified, preferably between 5 mm and 100 mm. The drain can thus be advantageously adapted to different modules, depending on the requirements.

[0095] Drain cleaning is also simplified.

[0096] Of course, many variations of these gutter embodiments are possible, in particular to modify the gutter profile and / or the shape of the drainage orifice(s).

[0097] The height of the drainage openings, i.e., the thickness of the bottom of the gutter at the level of the drainage openings, is preferably greater than 1 mm, preferably greater than 2 mm, preferably greater than 5 mm, preferably greater than 7 mm, and / or less than 20 mm. Advantageously, an opening shaped like a channel guides the flow of water and thus limits the flow cone under the drain. The opening can therefore be positioned at a reduced horizontal distance from the edge of the basin, which optimizes the amount of rainwater collected.

[0098] The dimensions of the drainage holes are not limited. Preferably, their equivalent diameter is less than 10 mm, preferably less than 8 mm and / or greater than 1 mm, preferably greater than 2 mm. This limits the risk of the entry of animals, for example birds or large insects, leaves, pine needles or other vegetation that could contaminate the basin.

[0099] The cumulative surface area of ​​the drainage orifice(s) is preferably greater than 40 mm2, preferably greater than 100 mm2, preferably greater than 200 mm2, preferably greater than 500 mm2 per meter of chute.

[0100] The optional filter, preferably removable, is positioned upstream of the discharge ports. The filter may in particular be in the form of a strainer or a grid 56, preferably metallic.

[0101] A strainer can be used in particular to cover a large drainage opening, for example, one with an equivalent diameter greater than 10 mm, 20 mm, 40 mm, 100 mm, or even 200 mm, especially a drainage opening located at one end of the channel, particularly when the channel is formed in a horizontal profiled cross member and has a solid bottom, except at its ends. In this embodiment, the strainer can be replaced by a local grid, that is, one that extends substantially only above the drainage opening.

[0102] The grid can be, for example, a perforated sheet, preferably made of aluminum, preferably placed on the bottom of the chute. Preferably, the equivalent diameter of the holes in the grid is less than 10 mm, preferably less than 8 mm and / or greater than 1 mm, preferably greater than 2 mm.

[0103] The grid can extend over all or part of the bottom of the gutter. Its dimensions are adapted so that it allows for the filtration of substantially all the rainwater received in the gutter.

[0104] The grid can be made up of one or more pieces.

[0105] In particular, when the length of the grate exceeds 1 m, 1.5 m, or 2 meters, its removal from the gutter can be difficult, especially through the upper opening of the gutter, which faces the bottom of the gutter. Handling the grate can, in particular, cause impurities, especially leaves, accumulated at the bottom of the drain, to fall into the basin.

[0106] In an embodiment not shown, the filter comprises a base extending against the bottom of the chute and rims extending along each long side of the chute, i.e., along the length of the chute, preferably substantially perpendicular to the base of the filter, and preferably over a height greater than 1 cm. Preferably, the filter also comprises a rim extending along one short side of the chute, i.e., along the width of the chute, preferably along each short side of the chute. This U-shaped or basket-like shape advantageously retains impurities, particularly during handling of the filter.

[0107] The edges also contribute to the rigidity of the filter by constituting stiffening ribs.

[0108] Preferably, the filter comprises, preferably is made of, a textile material, woven or non-woven, or of a foam. It is preferably made of a polymer or cellulosic material.

[0109] Advantageously, the texture of a textile or foam allows the impurities retained by the filter (leaves, sand, soil...) to catch and limits the risk of them falling into the basin when handling the filter.

[0110] The filter preferably has a density of less than 50 kg / m³, preferably less than 40 kg / m³, less than 35 kg / m³, and / or greater than 20 kg / m³, preferably greater than 25 kg / m³, preferably greater than 30 kg / m³, which is made possible in particular by a textile material, woven or non-woven, or a foam. Advantageously, this lightness further facilitates the handling of the filter and further limits the risk of impurities falling into the basin during filter handling.

[0111] In the service position, the filter extends to the bottom of the chute, between its right and left ends.

[0112] The filter is preferably self-supporting, that is to say that when the filter is held only by one of its right and left ends, it can flex under the effect of its weight, but without bending.

[0113] Preferably, the filter is such that, if it is dimensioned to have a length of 2 meters, when it is held, along a horizontal plane, only by its left end, its opposite right end deviates from said horizontal plane by less than 10 cm, preferably by less than 5 cm, or even by less than 3 cm.

[0114] In particular, when the filter comprises, preferably, a textile material, woven or non-woven, or a foam, the rigidity and / or dimensions of the filter can be determined to achieve self-support. In an embodiment not illustrated, the filter comprises a textile material, woven or non-woven, and / or a foam, and a stiffening core, for example made of plastic or metal, rigidly attached to the textile material and / or the foam.

[0115] Moreover, a grid is cumbersome.

[0116] In a preferred embodiment, the filter is deformable so as to be able to temporarily reduce its size and thus facilitate its removal from the chute. Preferably, it is deformable by hand, preferably can be compacted, preferably folded or compressed, preferably by hand. For example, a filter made of a textile can be rolled or folded upon itself; a filter made of a foam can be compressed, like a sponge.

[0117] The filter's deformability further facilitates cleaning, for example by allowing it to be washed in a washing machine. It also facilitates transport, as the filter can more easily be sent by mail.

[0118] Preferably, the filter retains substantially its hardness after immersion in water, the loss of hardness, measured according to EN105-EO2 and EN105-EO3 standards being preferably less than 20%, preferably less than 15%, preferably less than 10%.

[0119] Moreover, the equivalent diameters of the grid holes mentioned above do not allow for a perfect break in the flow velocity of rainwater. Using a textile material or foam is advantageous for slowing the flow of water. Foam, in particular, can act as a buffer, temporarily retaining water before releasing it drop by drop. This improves the filtration quality.

[0120] Remarkably, the inventor observed that a textile or foam material used does not constitute a breeding ground for fungi or mold, even if this material or foam remains damp longer than a grid. While not bound by this theory, he explains this result by the chlorinated vapors emanating from the pool and passing through the filter.

[0121] Preferably, the filter is chosen so as to retain all particles whose smallest dimension is greater than 5 mm, 3 mm, 2 mm or 500 microns.

[0122] Preferably, the filter is constructed in such a way as to prevent water from passing directly through it. In other words, its structure forces the water to follow meanders or "baffles" as it passes through it. The filtration quality is thus further improved. In this respect as well, a foam is particularly advantageous.

[0123] In one embodiment, the filter comprises, or is made of, a reactive material that chemically interacts with the rainwater passing through the filter, preferably to inject a product capable of modifying its pH, in particular to neutralize the rainwater, and / or a bactericidal product, for example, a chlorinated product. The reactive material may be a textile material or a filter foam, or coat the fibers of a textile material or the open cells of a foam. Advantageously, the quantity of said product is dosed in proportion to the quantity of rainwater, without operator intervention. This advantage is particularly useful when the pond has been at least partially emptied and is then gradually refilled with rainwater, especially during the wintering period.

[0124] The sinuosity of the water passages through the filter, i.e. the presence of said meanders, optional, advantageously leads to an increase in the contact time and the contact surface between the water and the filter, and thus promotes said chemical interaction.

[0125] In one embodiment, the reactive material is consumed under the effect of said interaction. In another embodiment, it can be regenerated.

[0126] The filter may be in the form of one or more blocks, preferably one or more blocks of a foam. The thickness of the block is preferably greater than 1 mm, preferably greater than 3 mm, preferably greater than 5 mm, preferably greater than 10 mm, preferably greater than 20 mm, preferably greater than 30 mm, and / or less than 80 mm, preferably less than 60 mm.

[0127] In a particular embodiment, the filter comprises a foam and / or a textile, preferably a textile, which covers the bottom 43 of the chute and, preferably, the side walls of the chute extending on each side of the chute from of the bottom 43. Preferably, the filter comprises a textile extending to the free edge of said side walls, preferably conforming to the bottom 43 and said side walls. The textile may, in particular, take the form of a basket extending along the entire length of the chute.

[0128] In a preferred embodiment, the filter is a foam, preferably synthetic, which advantageously is: - easy to work with (cutting, sizing); - lightweight, which facilitates its removal for cleaning or to improve ventilation; - easily replaceable; - easy to send by post, preferably after being rolled in an envelope.

[0129] Preferably, the pore size of the foam is between 2000 and 2500 micrometers.

[0130] Several foams have been studied, and in particular: - a polyurethane (PU) foam “KF” marketed by the company CRC Industries France SAS, for assembly and fixing applications; - a Cello® D2500 polyethylene foam, marketed by the company Recticel for insulation; - a "dryfeel S" type foam, marketed by the company Recticel, used for mattresses.

[0131] Tests have shown that this last foam allows water to pass through perfectly while effectively filtering impurities. It is preferred above all others.

[0132] The shutter 44 is preferably provided with a handle, not shown, to facilitate its manipulation by the user. The shape of the handle is not limiting. It may be replaced or supplemented by a hole in the shutter flap into which the user can insert a finger to pull the flap.

[0133] In the open position, the shutter protrudes from the plane of the chute opening by a height h44 of less than 8 cm, preferably less than 5 cm, preferably less than 4 cm, preferably less than 3 cm, and / or greater than 1 cm, preferably greater than 2 cm.

[0134] The shutter can take any shape.

[0135] Preferably, it has the form of a flap, mounted around a longitudinal axis of rotation Y, parallel to the X axis.

[0136] The shutter preferably has the general shape of a blade, preferably metallic, with a thickness preferably less than 10 mm, preferably less than 5 mm and / or greater than 1 mm, which preferably extends over the entire length of the chute.

[0137] The maximum opening angle of the shutter is preferably greater than 90°, preferably greater than 120°, preferably greater than 130°, and / or less than 180°, preferably less than 150°, preferably less than 140°, preferably about 135°.

[0138] Preferably, the hinge 58 around which the flap pivots extends along a lower longitudinal edge 59 of the gutter. The flap thus opens downwards, preferably in such a way that, in the open position, it forms an obstacle, in the form of a dam, in the event that rainwater overflows from the gutter. Furthermore, in such an overflow situation, the pressure of the rainwater on the flap advantageously tends to keep the flap in the open position.

[0139] Preferably, the chute is defined by the shape of a profile, and the hinge 58 is preferably partially defined by the shape of the profile, as illustrated in [Fig. 4]. Preferably, the shape of the profile limits the maximum degree of opening.

[0140] In the closed position, the flap limits the amount of rainwater entering the gutter, or even prevents rainwater from entering the gutter. The module then behaves like a conventional module.

[0141] Preferably, in the closed position, the flap extends in line with the infill plate that guides rainwater towards the drain. In other words, it fits within the geometric shape of the module's roof, which advantageously avoids obstructing the drainage of rainwater and other debris towards the module's edge beams.

[0142] In one embodiment, the drain includes an attachment 60, preferably manually deactivatable, preferably by simple manual pulling on the obturator, for example in the form of a clip, or an elastic hook, allowing the obturator to be held in the closed position.

[0143] The drain can also be used to selectively ventilate the module, depending on the position of the shutter. Ventilation, in the covered position, allows the hot air stored under the shelter to be evacuated during periods of high heat and / or preventively during prolonged absences, thus lowering the pool water temperature.

[0144] In one embodiment, the shutter can be immobilized in several opening positions, for example, two, three, or more than three different opening positions. All means of locking it in position are considered. In particular, the shutter can rub against the chute so as to remain locked in position when the user ceases to perform an action to open or close it.

[0145] Advantageously, the user can thus adjust the desired ventilation level, for example according to the ambient air temperature and the target water temperature.

[0146] In one embodiment, the module comprises several drains, preferably extending side by side, preferably aligned along the X-direction of movement. The ventilation level can be adjusted by opening one or more shutters. In one embodiment, the drains have different dimensions, for example, different lengths. With two drains, it is thus possible to have three (non-zero) ventilation levels. For the same purpose, a single drain can be equipped with several shutters, identical or different.

[0147] In one embodiment, the module has a right slope and a left slope, guiding rainwater towards the right and left edge rails, respectively. For example, the module has a curved or gabled roof, like a house roof. Preferably, the module includes a drain along each of the right and left edge rails, at the smallest possible horizontal distance from the right and left rails, but sufficient for the collected rainwater to fall into the basin. The opening of the two shutters advantageously creates an airflow between the two associated drains, thus effectively ventilating the shelter.

[0148] The operation of the shelter follows directly from the preceding description.

[0149] In the storage position, the modules are preferably stacked one on top of the other.

[0150] To deploy the shelter, the user pulls on the largest module in the direction of movement X. This module rolls along the deck in this direction, then pulls the module immediately below it into the storage position. The modules are thus driven successively until the pool is covered.

[0151] The spacing between the modules, i.e. the vertical operating clearance, is sufficient so that the modules can be moved to the overlapping position without their movements being hindered by the presence of the drains, even in the open position of the shutter.

[0152] Each module is preferably provided with at least one drain. Integrating the drain into an intermediate cross member advantageously limits the manufacturing costs of the module.

[0153] Depending on the water requirements in the basin and / or the desired ventilation, the user opens or closes one or more of the shutters.

[0154] In the closed position, the shutter is held by the fastener 60, which prevents the shutter from opening unintentionally, for example, due to wind. The shutter seals the gutter in a substantially watertight manner so that rainwater can flow from the ridge of the module, run down the shutter, and down to an edge cross member. Ventilation is minimal and thermal insulation is maximized.

[0155] The flap is preferably flush, that is to say it extends in line with at least the filler plate which is above the drain and through which rainwater flows to the drain.

[0156] To open a shutter, in this case a flap, the user pulls on the handle, which is conveniently accessible without needing to climb a ladder or use a tool. The fastener 60 can hold the flap, requiring the user to exert minimal force. The flap then rotates around its pivot axis Y until it reaches a maximum opening position, maximizing the clearance of the chute opening. In the maximum opening position, the angle of opening is approximately 135°. The weight of the flap then advantageously holds it in the open position. The dimensions of the flap advantageously allow it to avoid obstructing the movement of a module positioned above the drain during the deployment or storage of the shelter.

[0157] When it rains, rainwater falling on the part of the module's roof that is higher than the drain is directed towards the drain. If the flap is open, the water flows into the gutter, then through the drainage holes, before falling freely to the water in the basin. The elongated shape of a drainage hole helps guide the water before its free fall, thus limiting the flow cone during the free fall. The flow cone is the substantially conical envelope within which the rainwater exiting the drainage hole flows. Advantageously, virtually all the rainwater can thus fall into the basin, even if the horizontal distance between the drainage hole and the edge of the basin is small.

[0158] The presence of the gutter alters the trajectory of the rainwater and reduces its speed. This advantageously facilitates the vertical flow of rainwater towards the basin.

[0159] If the amount of rainwater is very high, for example during a downpour, the rainwater can accumulate in the deep gutter. If the rainwater flow rate is too high, the rainwater can overflow the gutter. The pivot point is located on the side of the edge rail, and the hinge is preferably continuous along the entire length of the flap, so that the flap forms a continuous barrier that retains the rainwater. Water recovery is advantageously optimized.

[0160] The grid filters rainwater and retains all unwanted objects, especially leaves. It also prevents animals from entering under the shelter through the gutter. To clean the grid, the user can pull it out of the gutter, preferably in the storage position.

[0161] As is now clear, the invention makes it possible to modify a module of a shelter according to the prior art at a limited cost and without modifying it The drain's operation is not affected, nor does it impact its certification. Its mechanically simple structure allows for efficient rainwater harvesting, particularly because, in the covered position, the drain, extending above the water in the basin, can be located near an edge beam, i.e., at the lower end of a slope in the module's roof. Furthermore, the drain helps regulate the temperature under the shelter. Finally, it is easily operated by the user, who can open or close it manually, without tools, according to their water and / or ventilation needs.

[0162] Of course, the invention is not limited to the embodiment described and represented.

[0163] In particular, in one embodiment, the shutter, preferably in the form of a flap, is mounted to rotate about two pivots 49.

[0164] Figures 6F and 7 illustrate a first preferred embodiment in which each pivot 49 has a plurality of flats 51 and the flap has a blade 52 elastically supported on flats 51 of the pivots. This elastic interaction between the pivots and the flap allows the flap to be snapped onto the pivots, preferably reversibly. The pivots are then fixed to the flap and rotate in their respective holes 50 when the flap is manipulated.

[0165] In another, unshown, variant, the pivots are fixed to the cheeks and therefore do not rotate with the shutter. Preferably, the interaction of the shutter and the pivots defines stable shutter positions, i.e., positions in which the operator must exert more force to move the shutter away from them. A stable position may, in particular, be the open position of the shutter or the closed position of the shutter. A stable position may also be an intermediate position between the open and closed positions of the shutter. With a pivot of the type shown in Figure 6F, the stable positions may be those in which the blade 52 rests on a flat surface and thus exerts minimal force on the pivot.

[0166] Furthermore, in a particularly advantageous embodiment illustrated in [Fig. 6], the drain 41 does not connect two hoops, and in particular two edge hoops. It is integrated into a filler plate 32. The length of the drain can be advantageously reduced, for example, to less than 2 m, 1.5 m, or 1 m. [Fig. 6] shows an example of such a "self-contained" drain, in the open (6A) and closed (6B) positions of the shutter.

[0167] Preferably, a self-contained drain comprises, at the right and left ends of the channel, cheeks 46 for sealing the channel, for example in the form of elastic plugs press-fitted to the ends of the channel. Figure 6C shows an example of a cheek 46.

[0168] In a preferred embodiment ([Fig.6]), the gutter is defined by the shape of two profiles 47 which are immobilized relative to each other by means of the cheeks 46, the profiles 47 being separated from each other to define a wide slot defining the drainage orifice 54. The profiles 47 preferably each have a groove 35 for receiving the filling plate on which the drain is mounted.

[0169] Preferably, the profiles have asperities, for example studs 48, arranged so as to facilitate the immobilization of the filter 54 in service, in particular of a filter in the form of a foam, as illustrated in Figure 6D. The asperities in particular prevent a foam that would be deformed by rainwater from escaping through the drainage opening.

[0170] In one embodiment, the cheeks are removable so that the drain can be disassembled, for example to facilitate its transport or installation.

[0171] Figure 6E shows the detail of Figure 6D after the shutter has been closed.

[0172] Preferably, the shutter is shaped like a flap. Preferably, the pivot axis of the flap is formed by two removable pivots 49 (Figure 6F). In one embodiment, at least one pivot 49 is snap-on, or "clip-on," into a cheek 46, preferably through a hole 50 provided in the cheek. Preferably, the pivot 49 is removable, preferably by hand, preferably unclippable, which allows the flap to be disassembled for easier cleaning.

[0173] The invention also relates to an installation kit for a self-contained drain in a filling plate 32, the kit comprising: - a self-contained drain according to the invention, preferably comprising - two 47 profiles to define the gutter and a drainage opening in the form of a slot, - two 46 mm cheeks to immobilize the two profiles relative to each other and to seal the ends of the gutter, - two pivots 49 which an operator can fix, preferably snap into place, in holes 50 made in the two cheeks, respectively, and - a shutter configured to be able to be mounted to rotate on the two pivots after the chute has been formed; - a template intended for making a cutout in the filling plate, sized to receive the drain; - optionally, a filler plate cutting tool.

[0174] To install the drain, an operator temporarily fixes the template to the infill panel at the drain's installation location. They then cut the infill panel along the template, using the cutting tool, to create a cutout, or "window," through the thickness of the infill panel, suitable for to receive the drain. After removing the template, he then secures the drain by sealing the cutout.

[0175] Preferably, the profiles are first fixed to the filler plate, then secured with the end caps. The chute profiles can be screwed onto the filler plate.

[0176] Then he clicks a first pivot onto the first cheek, inserts the first pivot into the first end of the flap, then clicks the second pivot onto the cheek by inserting it into the second end of the flap.

[0177] The kit thus makes it advantageous to equip a shelter already in use with a drain. It also avoids modifying the frame of the module.
