Definitions

  • the present invention relates to the field of swimming pools, and more particularly that of automatic cover devices for a swimming pool basin.
  • the invention is particularly suitable for a pool basin comprising a wall with non-right angles.
  • An automatic cover device for a swimming pool basin constitutes a protection making it possible to prevent debris, leaves or other dirt from falling into the swimming pool basin but also a safety device against drowning in the event of an accidental fall, for example of a child less than 5 years old.
  • An automatic cover device also keeps the pool water warm at night. For all these reasons, the use of automatic cover devices for swimming pools has developed.
  • an automatic pool basin cover device consists of a rolling shutter and comprises a floating apron - or cover - consisting of a plurality of floating slats assembled together.
  • the apron is adapted to be wound around a winding/unwinding axis (hereinafter “the axis”), for example a tube.
  • the axis a winding/unwinding axis
  • the floating apron In the "closed pool” position (hereinafter “closed position”), the floating apron is in the unrolled position: the floating apron is deployed on the surface of the water to cover the pool.
  • the floating apron In the "open pool” position (hereinafter “open position”), the floating apron is stored, rolled up around the winding/unwinding axis, leaving access to the pool free.
  • the swimming pool basin cover device can be arranged outside the swimming pool, possibly just at the edge of the swimming pool, the apron being rolled up around the axis in the "open swimming pool” position and then being out of the pool.
  • one way of proceeding is to fix transversely, on either side of the swimming pool basin and under the surface of the water, fixing means making it possible to fix the winding axis and possibly to other constituent elements of the covering device, such as a box covering the axis.
  • the role of the box can be aesthetic, by hiding the axis and the floating apron in the open position.
  • the casing can also contribute to safety by preventing access to the cover device and/or allowing a pool user to stand on it.
  • the floating apron In the open position, the floating apron is wrapped around the axle and is submerged.
  • FIG 1 illustrates such a cover device installed in a swimming pool 100.

  • the basin comprises a first wall A and a second opposite wall B, the walls A and B being able to delimit a length of the basin.
  • the covering device arranged close to a first wall (here, wall A), comprises a floating apron 110, or cover 110, here shown almost completely rolled up around a winding axis (the axis is therefore invisible) and comprising a plurality of floating slats assembled together.
  • the cover device illustrated comprises a box (or covering) consisting of a platform 150 supported by beams 130 and 140.
  • the platform 150 is for example a grating.
  • Platform 150 may include a grating or floor allowing a pool user to stand or sit on it.
  • the platform 150 is placed above the axle and therefore covers the axle and the floating deck wrapped around the axle when the cover device is in the open position.
  • the covering device also includes a vertical dividing wall 160 (partially shown in the figure 1 ), located at the front of the platform 150, separating the covering device from the pool itself.
  • the vertical dividing wall 160 and the platform 150 form a box covering the winding shaft and making it possible to protect it, particularly when the floating apron 110 is rolled around in the open position.
  • Platform 150 is typically located a few centimeters below the surface of the water so that the floating apron 110 can pass over it when unrolled.
  • the winding axis as well as the beam 140 are supported by flanges, or fixing means for the cover device, 120A and 120B fixed to the walls of the pool basin.

  • the platform 150 comprises a rear end, on the side of the wall A of the basin and a front end, shown in the figure 2 placed on the vertical partition wall 160.
  • An opening is provided for the passage of the floating apron 110 between the wall A and the rear end of the platform 150.
  • the direction of rotation of the winding/unwinding axis is chosen in order to allow the floating apron 110 to be unwound along the wall A of the swimming pool so that the apron 110 can pass through the opening located between the wall A of the basin and the rear end of the platform 150.

  • the cover device For the cover device to be accepted as a safety cover, it must meet a safety standard, for example the NF P90-308 standard defined by AFNOR (“Association facie de NORmalisation”). According to most standards, access to the mechanisms of a cover device must be protected.
  • the standard NF P90-308 defines more specifically that the horizontal opening through which the floating deck 110 passes between the wall A and the rear end of the platform 150.
  • This opening is a free passage, that is to say not closed by a valve or a shutter, whose mobility between an open position and a closed position would make it possible to selectively create an opening or protection against access to the floating apron.
  • This passage being left free, the standard indicates that it must have a maximum width “d” less than a predetermined value.

Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne le domaine des piscines, et plus particulièrement celui des dispositifs de couverture automatique pour un bassin de piscine. L'invention est en particulier adaptée pour un bassin de piscine comprenant une paroi avec des angles non droits.The present invention relates to the field of swimming pools, and more particularly that of automatic cover devices for a swimming pool basin. The invention is particularly suitable for a pool basin comprising a wall with non-right angles.

ARRIERE-PLAN TECHNIQUETECHNICAL BACKGROUND

Un dispositif de couverture automatique pour un bassin de piscine constitue une protection permettant d'empêcher des débris, feuilles ou autres saletés de tomber dans le bassin de la piscine mais aussi une sécurité contre les noyades en cas de chute accidentelle par exemple d'un enfant de moins de 5 ans. Un dispositif de couverture automatique permet aussi de garder la chaleur de l'eau du bassin la nuit. Pour toutes ces raisons, l'utilisation de dispositifs de couverture automatique de bassins de piscines s'est développée.An automatic cover device for a swimming pool basin constitutes a protection making it possible to prevent debris, leaves or other dirt from falling into the swimming pool basin but also a safety device against drowning in the event of an accidental fall, for example of a child less than 5 years old. An automatic cover device also keeps the pool water warm at night. For all these reasons, the use of automatic cover devices for swimming pools has developed.

Bien souvent, un dispositif de couverture automatique de bassin de piscine consiste en un volet roulant et comprend un tablier flottant - ou couverture -, constitué d'une pluralité de lattes flottantes assemblées les unes aux autres. Le tablier est adapté pour venir s'enrouler autour d'un axe d'enroulement/déroulement (ci-après « l'axe »), par exemple un tube. En position « piscine fermée » (ci-après « position fermée »), le tablier flottant est en position déroulée : le tablier flottant est déployé à la surface de l'eau pour recouvrir le bassin. En position « piscine ouverte » (ci-après « position ouverte »), le tablier flottant est rangé, enroulé autour de l'axe d'enroulement/déroulement, laissant l'accès au bassin libre.Very often, an automatic pool basin cover device consists of a rolling shutter and comprises a floating apron - or cover - consisting of a plurality of floating slats assembled together. The apron is adapted to be wound around a winding/unwinding axis (hereinafter “the axis”), for example a tube. In the "closed pool" position (hereinafter "closed position"), the floating apron is in the unrolled position: the floating apron is deployed on the surface of the water to cover the pool. In the "open pool" position (hereinafter "open position"), the floating apron is stored, rolled up around the winding/unwinding axis, leaving access to the pool free.

Le dispositif de couverture de bassin de piscine peut être disposé à l'extérieur de la piscine, possiblement juste au bord de la piscine, le tablier venant s'enrouler autour de l'axe en position « piscine ouverte » et étant alors hors de la piscine.The swimming pool basin cover device can be arranged outside the swimming pool, possibly just at the edge of the swimming pool, the apron being rolled up around the axis in the "open swimming pool" position and then being out of the pool.

Toutefois, souvent pour des raisons esthétiques, il est possible d'installer le dispositif de couverture directement dans la piscine, ce qui permet de le dissimuler, particulièrement quand il est en position ouverte.However, often for aesthetic reasons, it is possible to install the cover device directly in the swimming pool, which makes it possible to conceal it, particularly when it is in the open position.

Dans ce cas, une manière de procéder est de fixer transversalement, de part et d'autre du bassin de la piscine et sous la surface de l'eau, des moyens de fixations permettant de fixer l'axe d'enroulement et possiblement d'autres éléments constitutifs du dispositif de couverture, comme un caisson venant recouvrir l'axe. Le rôle du caisson peut être esthétique, en cachant l'axe et le tablier flottant dans la position ouverte. Le caisson peut aussi participer à la sécurité en empêchant l'accès au dispositif de couverture et/ou permettre à un utilisateur de la piscine de se tenir dessus. Dans la position ouverte, le tablier flottant est enroulé autour de l'axe et est immergé.In this case, one way of proceeding is to fix transversely, on either side of the swimming pool basin and under the surface of the water, fixing means making it possible to fix the winding axis and possibly to other constituent elements of the covering device, such as a box covering the axis. The role of the box can be aesthetic, by hiding the axis and the floating apron in the open position. The casing can also contribute to safety by preventing access to the cover device and/or allowing a pool user to stand on it. In the open position, the floating apron is wrapped around the axle and is submerged.

La figure 1 illustre un tel dispositif de couverture installé dans une piscine 100. La figure 1 est une vue d'une piscine 100 comprenant un bassin de piscine et un dispositif de couverture (ou volet roulant). Le bassin comprend une première paroi A et une deuxième paroi B opposée, les parois A et B pouvant délimiter une longueur du bassin. Le dispositif de couverture, disposé à proximité d'une première paroi (ici, la paroi A), comprend un tablier flottant 110, ou couverture 110, ici représenté presque totalement enroulé autour d'un axe d'enroulement (l'axe est donc invisible) et comprenant une pluralité de lattes flottantes assemblées les unes aux autres. Le dispositif de couverture illustré comprend un caisson (ou habillage) constitué d'une plate-forme 150 supportée par des poutrelles 130 et 140. La plate-forme 150 est par exemple un caillebotis. La plate-forme 150 peut comprendre un caillebotis ou un plancher permettant à un utilisateur de la piscine de se tenir debout ou assis dessus. La plate-forme 150 est placée au-dessus de l'axe et recouvre donc l'axe et le tablier flottant enroulé autour de l'axe quand le dispositif de couverture est en position ouverte. Le dispositif de couverture comprend aussi une paroi de séparation verticale 160 (partiellement représentée sur la figure 1), située à l'avant de la plate-forme 150, séparant le dispositif de couverture du bassin proprement dit. La paroi de séparation verticale 160 et la plate-forme 150 forment un caisson recouvrant l'axe d'enroulement et permettant de le protéger, particulièrement quand le tablier flottant 110 est enroulé autour dans la position ouverte. La plate-forme 150 est située classiquement quelques centimètres sous la surface de l'eau afin que le tablier flottant 110 puisse passer par-dessus lorsqu'il est déroulé. Dans l'exemple illustré, l'axe d'enroulement ainsi que la poutrelle 140 sont supportés par des flasques, ou moyens de fixations pour le dispositif de couverture, 120A et 120B fixées sur les parois du bassin de la piscine.There figure 1 illustrates such a cover device installed in a swimming pool 100. The figure 1 is a view of a swimming pool 100 comprising a swimming pool basin and a covering device (or rolling shutter). The basin comprises a first wall A and a second opposite wall B, the walls A and B being able to delimit a length of the basin. The covering device, arranged close to a first wall (here, wall A), comprises a floating apron 110, or cover 110, here shown almost completely rolled up around a winding axis (the axis is therefore invisible) and comprising a plurality of floating slats assembled together. The cover device illustrated comprises a box (or covering) consisting of a platform 150 supported by beams 130 and 140. The platform 150 is for example a grating. Platform 150 may include a grating or floor allowing a pool user to stand or sit on it. The platform 150 is placed above the axle and therefore covers the axle and the floating deck wrapped around the axle when the cover device is in the open position. The covering device also includes a vertical dividing wall 160 (partially shown in the figure 1 ), located at the front of the platform 150, separating the covering device from the pool itself. The vertical dividing wall 160 and the platform 150 form a box covering the winding shaft and making it possible to protect it, particularly when the floating apron 110 is rolled around in the open position. Platform 150 is typically located a few centimeters below the surface of the water so that the floating apron 110 can pass over it when unrolled. In the example shown, the winding axis as well as the beam 140 are supported by flanges, or fixing means for the cover device, 120A and 120B fixed to the walls of the pool basin.

La figure 2 illustre une vue de profil du dispositif de couverture de la figure 1. L'axe 270 est situé à proximité d'une paroi du bassin délimitant la longueur du bassin de la piscine 100 (ici, la paroi A). La plate-forme 150 comprend une extrémité arrière, du côté de la paroi A du bassin et une extrémité avant, représentée dans la figure 2 posée sur la paroi de séparation verticale 160. Une ouverture est ménagée pour le passage du tablier flottant 110 entre la paroi A et l'extrémité arrière de la plate-forme 150. Comme cela est visible sur les figures 1 et 2, le sens de rotation de l'axe d'enroulement/déroulement est choisi afin de permettre de dérouler le tablier flottant 110 le long de la paroi A de la piscine pour que le tablier 110 puisse passer par l'ouverture située entre la paroi A du bassin et l'extrémité arrière de la plate-forme 150. Lorsque le tablier flottant 110 est ainsi déroulé du côté de l'extrémité arrière de la plate-forme 150, son extrémité libre (i. e. son extrémité non directement attachée à l'axe d'enroulement/déroulement 270) remonte jusqu'à la surface de l'eau, puis bascule en direction de la paroi opposée du bassin (la paroi B, non représentée dans la figure 2). La bascule de l'extrémité libre du tablier flottant 110 du bon côté (c'est-à-dire en direction de la paroi B) peut être obtenu au moyen d'un lest placé dans cette extrémité libre ou grâce à la forme de l'extrémité libre. Dans la position fermée, le tablier flottant 110 est totalement déroulé et recouvre la surface de l'eau du bassin. Ainsi, dans la position fermée, l'extrémité libre du tablier flottant 110 est en butée contre la paroi B, et l'extrémité du tablier flottant 110 reliée à l'axe 270, possiblement via des lanières ou sangles, est en butée contre la paroi A.There figure 2 illustrates a profile view of the cover device of the figure 1 . The axis 270 is located close to a wall of the basin delimiting the length of the basin of the swimming pool 100 (here, the wall A). The platform 150 comprises a rear end, on the side of the wall A of the basin and a front end, shown in the figure 2 placed on the vertical partition wall 160. An opening is provided for the passage of the floating apron 110 between the wall A and the rear end of the platform 150. As can be seen on the figure 1 And 2 , the direction of rotation of the winding/unwinding axis is chosen in order to allow the floating apron 110 to be unwound along the wall A of the swimming pool so that the apron 110 can pass through the opening located between the wall A of the basin and the rear end of the platform 150. When the floating apron 110 is thus unrolled on the side of the rear end of the platform 150, its free end (ie its end not directly attached to the axis winding / unwinding 270) rises to the surface of the water, then tilts in the direction of the opposite wall of the pool (the wall B, not shown in the picture 2 ). The rocking of the free end of the floating deck 110 on the right side (that is to say in the direction of the wall B) can be obtained by means of a ballast placed in this free end or thanks to the shape of the free end. In the closed position, the floating apron 110 is completely unrolled and covers the surface of the water in the pool. Thus, in the closed position, the free end of the floating apron 110 is in abutment against the wall B, and the end of the floating apron 110 connected to the axis 270, possibly via straps or straps, is in abutment against the wall A.

Pour que le dispositif de couverture soit accepté comme une couverture de sécurité, il doit répondre à une norme de sécurité, par exemple la norme NF P90-308 définie par l'AFNOR (« Association Française de NORmalisation »). Selon la plupart des normes, les accès aux mécanismes d'un dispositif de couverture doivent être protégés. La plate-forme 150 et la paroi verticale 160, formant un caisson autour de l'axe 270, permettent ainsi de protéger l'accès aux mécanismes, particulièrement à l'axe 270. La norme NF P90-308 définit plus spécifiquement que l'ouverture horizontale par laquelle passe le tablier flottant 110 entre la paroi A et l'extrémité arrière de la plate-forme 150. Cette ouverture est un passage libre, c'est-à-dire non obturé par un clapet ou un volet, dont la mobilité entre une position ouverte et une position fermée permettrait de, sélectivement, réaliser une ouverture ou une protection contre l'accès au tablier flottant. Ce passage étant laissé libre, la norme indique qu'il doit avoir une largeur maximum « d » inférieure à une valeur prédéterminée. Cette valeur prédéterminée peut être définie par une norme, par exemple la norme NF P90-308. Cette valeur prédéterminée est par exemple égale à 80 mm selon la norme NF P90-308 publiée en 2013.For the cover device to be accepted as a safety cover, it must meet a safety standard, for example the NF P90-308 standard defined by AFNOR (“Association Française de NORmalisation”). According to most standards, access to the mechanisms of a cover device must be protected. The platform 150 and the vertical wall 160, forming a box around the axis 270, thus make it possible to protect access to the mechanisms, particularly to the axis 270. The standard NF P90-308 defines more specifically that the horizontal opening through which the floating deck 110 passes between the wall A and the rear end of the platform 150. This opening is a free passage, that is to say not closed by a valve or a shutter, whose mobility between an open position and a closed position would make it possible to selectively create an opening or protection against access to the floating apron. This passage being left free, the standard indicates that it must have a maximum width “d” less than a predetermined value. This predetermined value can be defined by a standard, for example standard NF P90-308. This predetermined value is for example equal to 80 mm according to standard NF P90-308 published in 2013.

Toutefois, cette contrainte de largeur maximale de l'ouverture entre la paroi et l'extrémité arrière de la plate-forme peut ne plus pouvoir être respectée par un dispositif de couverture connu tel que précédemment décrit lorsque le bassin comprend par exemple au moins un angle arrondi, ou encore un pan coupé, ou toute forme créant une réduction de la largeur du bassin du côté de la paroi A, ici deux angles arrondis, comme illustré dans la figure 3.However, this constraint of maximum width of the opening between the wall and the rear end of the platform may no longer be able to be respected by a known covering device as previously described when the pool comprises for example at least one angle rounded, or even a cutaway, or any shape creating a reduction in the width of the pool on the side of wall A, here two rounded corners, as illustrated in the picture 3 .

La figure 3 comprend une figure 3A et une figure 3B. La figure 3A illustre une vue de dessus d'un bassin d'une piscine comprenant des angles arrondis entre deux parois verticales adjacentes. La figure 3B illustre une vue de profil d'un dispositif de couverture similaire au dispositif de couverture précédemment décrit et placé contre une paroi d'un bassin comprenant des angles arrondis. La zone 380 du bassin, matérialisée sur les figures 3A et 3B par des hachures, correspond à une zone dans laquelle la largeur du bassin est inférieure à la largeur du reste du bassin du fait de la présence des arrondis aux angles. Ainsi les arrondis se situent en la paroi A et les deux autres parois verticales du bassin, adjacentes à la paroi A. Cette zone 380 s'étend sur une distance « a » depuis la paroi A. Un tablier flottant 310, ayant vocation à recouvrir la surface du bassin dans la position fermée, comprend, pour une grande partie, des lattes flottantes ayant une largeur égale à la largeur du bassin. L'axe d'enroulement 370 ne peut donc pas être installé trop proche de la paroi A afin que le tablier 310 ne soit pas enroulé ou déroulé dans la zone 380, ladite zone 380 n'étant pas assez large pour le passage des lattes du tablier flottant 310. La largeur minimale de l'ouverture de largeur « d » par laquelle passe le tablier 310 entre la paroi A et l'extrémité arrière de la plate-forme 350 est donc contrainte par les angles arrondis formés à la jonction des parois verticales du bassin. Plus précisément la largeur minimale de l'ouverture de largeur « d » est contrainte par la distance « a », la largeur « d » ne pouvant pas être inférieure à la distance « a ». Ainsi, selon l'importance de l'arrondi, et donc selon la valeur de « a », il n'est pas possible d'avoir une ouverture avec une largueur « d » respectant par exemple les contraintes de la norme NF P90-308.There picture 3 includes a Figure 3A and an Figure 3B . There Figure 3A illustrates a top view of a swimming pool basin comprising rounded corners between two adjacent vertical walls. There Figure 3B illustrates a side view of a cover device similar to the cover device previously described and placed against a wall of a pool comprising rounded corners. Zone 380 of the basin, materialized on the figures 3A and 3B by hatching, corresponds to an area in which the width of the pool is less than the width of the rest of the pool due to the presence of rounded corners. Thus the roundings are located in the wall A and the two other vertical walls of the basin, adjacent to the wall A. This zone 380 extends over a distance "a" from the wall A. A floating apron 310, intended to cover the surface of the basin in the closed position comprises, for a large part, floating slats having a width equal to the width of the basin. The winding axis 370 cannot therefore be installed too close to the wall A so that the apron 310 is not rolled up or unrolled in the zone 380, said zone 380 not being wide enough for the passage of the slats of the floating deck 310. The minimum width of the opening of width "d" through which the deck 310 passes between the wall A and the rear end of the platform 350 is therefore constrained by the rounded corners formed at the junction of the walls vertical of the basin. More specifically, the minimum width of the opening of width “d” is constrained by the distance “a”, the width “d” not being able to be less than the distance “a”. Thus, according to the importance of the rounding, and therefore according to the value of "a", it is not possible to have an opening with a width "d" respecting for example the constraints of standard NF P90-308 .

Certaines solutions ont été développées consistant en l'ajout d'une poutrelle supplémentaire contre la paroi ou d'une trappe permettant de refermer l'ouverture lorsque le dispositif de couverture est dans la position ouverte. Il s'agit notamment de fournir un clapet ou un volet qui vient obturer la zone de passage du tablier flottant 110 permettant de, sélectivement, réaliser l'ouverture d'accès au tablier flottant ou une protection contre l'accès au tablier flottant. La zone de passage du tablier flottant 110 n'est ainsi plus libre, puisqu'il n'y a plus d'ouverture lorsque le tablier flottant est en position ouverte. Ces solutions sont toutefois complexes à mettre en œuvre et couteuses en matériel supplémentaire, et il peut être préféré de laisser une ouverture, c'est-à-dire un passage libre pour le tablier flottant, évitant de recourir à des parties mobiles pour la plate-forme 350.Certain solutions have been developed consisting of the addition of an additional beam against the wall or of a hatch making it possible to close the opening when the covering device is in the open position. This is in particular to provide a valve or a shutter which closes off the passage zone of the floating apron 110 making it possible, selectively, to make the access opening to the floating apron or a protection against access to the floating apron. The passage zone of the floating apron 110 is thus no longer free, since there is no longer any opening when the floating apron is in the open position. However, these solutions are complex to implement and costly in terms of additional equipment, and it may be preferred to leave an opening, that is to say a free passage for the floating deck, avoiding the need for moving parts for the platform. -shape 350.

Il est donc nécessaire de proposer une solution permettant de répondre au problème de l'installation, en conformité avec une norme de sécurité, d'un dispositif de couverture dans une piscine comprenant un bassin avec une paroi comprenant par exemple des angles arrondis, le dispositif de couverture devant être placé contre cette paroi.It is therefore necessary to propose a solution making it possible to respond to the problem of the installation, in accordance with a safety standard, of a cover device in a swimming pool comprising a basin with a wall comprising for example rounded corners, the device of cover to be placed against this wall.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

L'invention présentée permet de résoudre le problème de l'installation d'un dispositif de couverture automatique, comprenant une plate-forme, immergée dans un bassin d'une piscine, lorsque le bassin comprend une paroi contre laquelle est disposé le dispositif de couverture, ladite paroi comprenant par exemple des angles non droits (les deux parois verticales adjacentes ne formant pas une intersection selon un angle droit). Plus précisément, le dispositif de couverture selon l'invention peut être installé à proximité d'une paroi d'un bassin quand bien même ladite paroi comprendrait des angles arrondis, formés entre deux parois verticales adjacentes, ou tout autre caractéristique réduisant la largeur du bassin à proximité de la paroi ou plus généralement empêchant un tablier flottant d'être proche de la paroi (c'est-à-dire de venir en butée contre la paroi). L'invention peut ainsi être mise en œuvre lorsqu'un obstacle ou une protubérance est présent le long de la paroi.The invention presented makes it possible to solve the problem of the installation of an automatic cover device, comprising a platform, immersed in a basin of a swimming pool, when the basin comprises a wall against which the cover device is placed. , said wall comprising for example non-right angles (the two adjacent vertical walls not forming an intersection at a right angle). More specifically, the cover device according to the invention can be installed close to a wall of a pool even if said wall includes rounded corners, formed between two adjacent vertical walls, or any other characteristic reducing the width of the pool. close to the wall or more generally preventing a floating deck from being close to the wall (that is to say from coming into abutment against the wall). The invention can thus be implemented when an obstacle or a protuberance is present along the wall.

L'invention permet de résoudre le problème de l'installation d'un dispositif de couverture immergé dans un bassin d'une piscine comprenant une première paroi, la piscine comprenant une autre paroi adjacente à la première paroi du bassin (les deux parois définissant un angle de jonction à leur intersection), l'angle de jonction des deux parois n'étant pas droit mais, par exemple, arrondi. Dit autrement, le dispositif de couverture selon l'invention peut être installé à proximité, ou contre, une paroi d'une piscine formant un angle arrondi ou un pan coupé avec une paroi adjacente ou comprenant une forme irrégulière. Ainsi la forme de la piscine, vu du dessus peut présenter des angles de jonction, autre que droit, entre les parois adjacentes. En d'autres termes les parois adjacentes verticales de la piscine peuvent se rejoindre avec des angles non droits, tel qu'avec congés ou des arrondis, ou encore des chanfreins, ou tout autre jonction à angle non droit.The invention solves the problem of installing a submerged cover device in a swimming pool basin comprising a first wall, the swimming pool comprising another wall adjacent to the first wall of the basin (the two walls defining a junction angle at their intersection), the junction angle of the two walls not being straight but, for example, rounded. In other words, the cover device according to the invention can be installed close to, or against, a wall of a swimming pool forming a rounded angle or a cut face with an adjacent wall or comprising an irregular shape. Thus the shape of the swimming pool, seen from above, may have junction angles, other than straight, between the adjacent walls. In other words, the vertical adjacent walls of the swimming pool can be joined with non-right angles, such as with fillets or roundings, or even chamfers, or any other non-right angle junction.

Les figures 1 à 3 ont été précédemment décrites.THE figures 1 to 3 have been previously described.

La figure 4 illustre une vue de profil d'un dispositif de couverture 400 d'un bassin de piscine selon un mode de réalisation de l'invention.There figure 4 illustrates a side view of a cover device 400 for a swimming pool basin according to one embodiment of the invention.

Le dispositif de couverture 400 pour un bassin d'une piscine comprend une position fermée et une position ouverte. Le bassin de la piscine, similaire au bassin illustré dans la figure 1, comprend deux parois opposées A et B délimitant la longueur du bassin (la paroi B n'est pas représentée). Le dispositif de couverture 400 comprend un axe d'enroulement 470 immergé et disposé à proximité d'une première paroi du bassin (ici, la paroi A). Le dispositif de couverture 400 comprend un tablier flottant 410, adapté pour recouvrir le bassin de la piscine dans la position fermée et pour être enroulé autour de l'axe d'enroulement 470 dans la position ouverte. Le dispositif de couverture 400 comprend une plate-forme 450 immergée, par exemple un caillebotis 450, recouvrant l'axe d'enroulement 470 et le tablier flottant 410 enroulé dans la position fermée. La plate-forme 450 comprend une première extrémité, dite arrière, du côté de la première paroi A et une deuxième extrémité, dite avant, du côté opposé à la première paroi A, c'est-à-dire du côté de la deuxième paroi B. Le dispositif de couverture 400 comprend une ouverture O du côté de l'extrémité avant de la plate-forme 450, l'ouverture O permettant un passage du tablier flottant entre la position ouverte et la position fermée du dispositif de couverture. Dit autrement, l'ouverture O permet un passage du tablier flottant 410 lorsque le dispositif de couverture 400 passe de la position ouverte à la position fermée (et vice-versa). L'ouverture O est située du côté de l'extrémité avant de la plate-forme 450, ici sous une poutrelle 430 supportant la plate-forme 450 avec la poutrelle 440. L'ouverture O est un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte. Du fait de ce passage libre formant l'ouverture, les dimensions de l'ouverture O peuvent devoir respecter certaines valeurs prédéterminées. Ces valeurs peuvent être définies par une norme, par exemple la norme NF P90-308. Ainsi, par exemple, la norme NF P90-308 publiée en 2013 définie que la largeur de l'ouverture O, ou la largeur de tout passage libre permettant d'accéder au mécanisme du tablier flottant (c'est-à-dire ici la distance entre le bas de la poutrelle 430 et le haut d'une paroi de séparation verticale 460) doit être inférieure à 100 millimètres.The cover device 400 for a swimming pool basin comprises a closed position and an open position. The swimming pool basin, similar to the basin illustrated in the figure 1 , comprises two opposite walls A and B delimiting the length of the pool (wall B is not shown). The covering device 400 comprises a winding axis 470 immersed and arranged close to a first wall of the pool (here, wall A). The cover device 400 includes a floating apron 410, adapted to cover the pool basin in the closed position and to be wrapped around the winding shaft 470 in the open position. The covering device 400 comprises a submerged platform 450, for example a grating 450, covering the winding axis 470 and the floating apron 410 rolled up in the closed position. The platform 450 comprises a first end, called the rear, on the side of the first wall A and a second end, called the front, on the side opposite the first wall A, that is to say on the side of the second wall B. The covering device 400 comprises an opening O on the side of the front end of the platform 450, the opening O allowing passage of the floating apron between the open position and the closed position of the covering device. In other words, the opening O allows passage of the floating apron 410 when the covering device 400 passes from the open position to the closed position (and vice versa). The opening O is located on the side of the front end of the platform 450, here under a beam 430 supporting the platform 450 with the beam 440. The opening O is a free passage, i.e. that is, not closed off by a valve or a shutter which would be movable between a closed and an open position. Due to this free passage forming the opening, the dimensions of the opening O may have to respect certain predetermined values. These values can be defined by a standard, for example standard NF P90-308. Thus, for example, standard NF P90-308 published in 2013 defines that the width of the opening O, or the width of any free passage allowing access to the mechanism of the floating apron (i.e. here the distance between the bottom of the beam 430 and the top of a vertical dividing wall 460) must be less than 100 millimeters.

Selon un mode de réalisation de l'invention, la première extrémité, dite arrière, de la plate-forme 450 prévue pour être positionnée à proximité de la paroi A comprend une forme permettant de venir en appui contre la paroi A. Selon un mode de réalisation de l'invention, par « en appui contre la paroi A », il faut comprendre que la forme de la première extrémité dite arrière de la plate-forme 450 est adaptée pour être placée à proximité de la paroi A sans laisser de jeu entre le bord de la première extrémité et la paroi, ou bien en laissant un jeu de largeur maximal inférieure à une valeur prédéterminée, par exemple définie par une norme telle que la norme NF P90 308. Dit autrement, la forme de la première extrémité dite arrière de la plate-forme est adaptée pour « épouser » la forme de la paroi A, particulièrement ses éventuelles angles arrondis aux jonctions avec les parois verticales adjacentes. Par « épouser », il faut comprendre qu'un jeu entre la première extrémité dite arrière de la plate-forme 450 et la paroi A est inférieur à une valeur prédéterminée. Selon un mode de réalisation de l'invention, la valeur prédéterminée est définie dans une norme de sécurité, par exemple la norme NF P90-308. Dans ce cas, l'ouverture avec une largueur « d » devant respecter les contraintes de la norme NF P90-308 correspond au jeu entre la première extrémité dite arrière de la plate-forme 450 et la paroi A. Cette ouverture est un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte.According to one embodiment of the invention, the first end, called the rear end, of the platform 450 provided to be positioned close to the wall A comprises a shape making it possible to bear against the wall A. According to one mode of embodiment of the invention, by " bearing against the wall A ", it should be understood that the shape of the first so-called rear end of the platform 450 is adapted to be placed close to the wall A without leaving any play between the edge of the first end and the wall, or else by leaving a clearance of maximum width less than a predetermined value, for example defined by a standard such as standard NF P90 308. In other words, the shape of the first so-called rear end of the platform is adapted to "match" the shape of the wall A, particularly its possible rounded corners at the junctions with the adjacent vertical walls. By “matching”, it should be understood that a clearance between the first so-called rear end of the platform 450 and the wall A is less than a predetermined value. According to one embodiment of the invention, the predetermined value is defined in a safety standard, for example standard NF P90-308. In this case, the opening with a width "d" that must comply with the constraints of the NF P90-308 standard corresponds to the clearance between the first so-called rear end of the platform 450 and the wall A. This opening is a free passage , that is to say not closed by a valve or a shutter which would be movable between a closed and open position.

La plate-forme 450 est immergée à une profondeur « h » au moins égale à une profondeur minimale déterminée en fonction d'un rayon de courbure du tablier flottant 410. Le rayon de courbure du tablier flottant 410 est d'autant plus petit que le tablier flottant 410 peut être replié sur lui-même, ou, dit autrement, que le tablier flottant 410 peut être considéré comme « souple ». Dit autrement, le rayon de courbure du tablier flottant est d'autant plus petit que le tablier flottant peut être enroulé facilement sur lui-même. On notera que le rayon de courbure du tablier flottant 410 est normalement inférieur ou égal au rayon de l'axe 470 d'enroulement/déroulement du tablier flottant 410 afin que le tablier flottant 410 puisse être enroulé autour de l'axe 470 sans risquer d'être abimé.The platform 450 is submerged to a depth "h" at least equal to a minimum depth determined according to a radius of curvature of the floating apron 410. The radius of curvature of the floating apron 410 is all the smaller as the floating apron 410 can be folded back on itself, or, in other words, the floating apron 410 can be considered "flexible". In other words, the radius of curvature of the floating apron is all the smaller as the floating apron can be rolled up easily on itself. It will be noted that the radius of curvature of the floating apron 410 is normally less than or equal to the radius of the axis 470 for rolling up/unwinding the floating apron 410 so that the floating apron 410 can be rolled up around the axis 470 without risking to be damaged.

Cette profondeur « h » correspond à l'espace nécessaire entre la surface de l'eau et la plate-forme 450 pour que le tablier flottant 410 puisse se dérouler normalement sans s'accrocher à une quelconque surface, particulièrement, comme expliqué ci-après, lorsque le tablier flottant 410 est arrivé en butée contre la paroi B et se déroule ensuite vers la paroi A.This depth "h" corresponds to the space necessary between the surface of the water and the platform 450 so that the floating apron 410 can unroll normally without clinging to any surface, particularly, as explained below, when the floating deck 410 has come into abutment against the wall B and then unrolls towards the wall A.

Selon un mode de réalisation de l'invention, la plate-forme 450 est immergée à une profondeur « h » au moins égale à deux fois le rayon de courbure du tablier flottant 410.According to one embodiment of the invention, the platform 450 is submerged to a depth "h" at least equal to twice the radius of curvature of the floating apron 410.

Selon un mode de réalisation de l'invention, le sens de rotation de l'axe d'enroulement/déroulement 470 est adapté pour dérouler le tablier flottant 410 du côté de l'axe d'enroulement/déroulement 470 opposé à la paroi A, c'est-à-dire du côté opposé à la paroi contre laquelle est disposé le dispositif de couverture 400. Dit autrement, le sens de rotation de l'axe d'enroulement/déroulement 470 permet de dérouler le tablier flottant 410 du côté de l'ouverture O, située du côté de l'extrémité avant de la plate-forme 450. Encore autrement dit, le sens de rotation de l'axe d'enroulement/déroulement 470 permet de dérouler le tablier flottant 410 du côté de l'extrémité avant de la plate-forme afin que l'extrémité libre du tablier flottant 410 remonte vers l'ouverture O, possiblement guidée par un moyen de guidage, au fur et à mesure que l'axe 470 est déroulé. Ce sens de rotation permettant au tablier 410 d'être déroulé afin de passer de la position ouvert (tablier 410 enroulé autour de l'axe 470) à la position fermée (tablier 410 déroulé et recouvrant la surface du bassin) est représenté dans la figure 4 par la flèche F. Ce sens de rotation F permet de dérouler la tablier 410 avec son extrémité libre qui remonte du côté de l'extrémité avant de la plate-forme 450, ou sensiblement sous l'extrémité avant de la plate-forme 450. Ce sens de rotation F pour le déroulement du tablier 410 est le sens de rotation opposé au sens de rotation de déroulement habituel utilisé pour les dispositifs de couverture traditionnels décrits dans les figures 1 à 3. Utiliser un sens de rotation F contraire au sens de rotation habituellement utilisé permet avantageusement de dérouler le tablier 410 avec son extrémité libre placé directement du côté de l'ouverture O de sortie du tablier, c'est-à-dire du côté de l'extrémité avant de la plate-forme 450. Ce sens de rotation F permet d'éviter que le tablier 410 ne s'accroche sous la surface de la plate-forme 450 lors de son déroulement et facilite sa sortie (ou entrée) par l'ouverture O. Il est à noter que le tablier flottant 410 est enroulé autour de l'axe 470 en mettant en rotation l'axe d'enroulement 470 dans le sens de rotation opposé au sens de rotation F.According to one embodiment of the invention, the direction of rotation of the winding/unwinding axis 470 is adapted to unwind the floating apron 410 on the side of the winding/unwinding axis 470 opposite to the wall A, that is to say on the side opposite the wall against which the covering device 400 is arranged. the opening O, located on the side of the front end of the platform 450. Still in other words, the direction of rotation of the winding/unwinding axis 470 makes it possible to unroll the floating apron 410 on the side of the front end of the platform so that the free end of the floating apron 410 rises towards the opening O, possibly guided by a guide means, as the axis 470 is unwound. This direction of rotation allowing the apron 410 to be unrolled in order to pass from the open position (apron 410 rolled up around the axis 470) to the closed position (apron 410 unrolled and covering the surface of the basin) is represented in the figure 4 by the arrow F. This direction of rotation F makes it possible to unroll the apron 410 with its free end which rises on the side of the front end of the platform 450, or substantially under the front end of the platform 450. This direction of rotation F for the unwinding of the apron 410 is the opposite direction of rotation to the direction of usual unwinding rotation used for the traditional covering devices described in the figures 1 to 3 . Using a direction of rotation F contrary to the direction of rotation usually used advantageously makes it possible to unroll the apron 410 with its free end placed directly on the side of the outlet opening O of the apron, that is to say on the side of the front end of the platform 450. This direction of rotation F makes it possible to prevent the apron 410 from catching under the surface of the platform 450 during its unwinding and facilitates its exit (or entry) by the opening O. It should be noted that the floating apron 410 is wound around the axis 470 by rotating the winding axis 470 in the direction of rotation opposite to the direction of rotation F.

Selon un mode de réalisation complémentaire de l'invention, le dispositif de couverture 400 comprend un moyen de guidage 480 du tablier 470 sous l'extrémité avant de la plate-forme 450 (ici, représenté sous la poutrelle 430). Ce moyen de guidage 480 permet de guider l'extrémité libre du tablier 410 lorsque le tablier 410 est déroulé afin de s'assurer que le tablier 410 sort bien via l'ouverture O sans s'accrocher à un obstacle. Le moyen de guidage 480 peut comprendre une pièce tubulaire de section sensiblement triangulaire comme représenté sur la figure 4 afin de guider le tablier 410 lors de son déroulement.According to a complementary embodiment of the invention, the covering device 400 comprises a guide means 480 of the apron 470 under the front end of the platform 450 (here, represented under the beam 430). This guide means 480 makes it possible to guide the free end of the apron 410 when the apron 410 is unrolled in order to ensure that the apron 410 comes out via the opening O without clinging to an obstacle. The guide means 480 may comprise a tubular piece of substantially triangular section as shown in the figure 4 in order to guide the apron 410 during its unwinding.

Selon un mode de réalisation alternatif de l'invention, le moyen de guidage 480 peut permettre l'utilisation d'un axe 410 ayant un sens de rotation classique (i. e. déroulement du tablier 410 avec un sens de rotation opposé au sens de rotation F), c'est-à-dire dans lequel l'extrémité libre remonte le long de la paroi A lors du déroulement du tablier 410. Dans ce cas, le moyen de guidage 480 peut guider l'extrémité libre du tablier 410 afin qu'elle sorte (et rentre) via l'ouverture O sans s'accrocher sous le caillebotis 450.According to an alternative embodiment of the invention, the guide means 480 can allow the use of a shaft 410 having a conventional direction of rotation (i.e. unwinding of the apron 410 with a direction of rotation opposite to the direction of rotation F) , that is to say in which the free end goes up along the wall A during the unwinding of the apron 410. In this case, the guide means 480 can guide the free end of the apron 410 so that it exit (and enter) via opening O without getting caught under the 450 grating.

Le moyen de guidage 480 peut comprendre des lanières (ou tout autre moyen de liaison, comme des sangles, cordes, cordages, filets, etc.) fixées d'un côté à l'extrémité avant de la plate-forme 450, au-dessus de l'ouverture O, et comprenant de l'autre côté des poids suspendus placés entre la paroi A et l'axe 470.The guide means 480 can comprise straps (or any other connecting means, such as straps, cords, ropes, nets, etc.) fixed on one side to the front end of the platform 450, above of the opening O, and comprising on the other side suspended weights placed between the wall A and the axis 470.

Selon un mode de réalisation de l'invention, le dispositif de couverture 400 comprend une paroi de séparation verticale 460 devant la plate-forme 450 et formant un caisson autour de l'axe d'enroulement 470. L'ouverture « O » pour le passage du tablier flottant 410 peut être située en haut de cette paroi de séparation verticale 460. L'ouverture O est alors positionnée verticalement. De même que pour les modes de réalisation précédents, cette ouverture constitue un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte. Selon un mode de réalisation préférentiel, la distance « e » entre la paroi de séparation verticale 460 et le tablier flottant 410 enroulé autour de l'axe d'enroulement 470 dans la position ouverte (i. e. quand le tablier flottant 410 est totalement enroulé autour de l'axe 470) est au moins égale à une valeur prédéterminée, par exemple déterminée en fonction de l'épaisseur du tablier flottant 410. Selon un mode de réalisation de l'invention, cette distance « e » est au moins égale à 7 centimètres. Cette distance minimale entre la paroi de séparation verticale 460 et le tablier flottant 410 enroulé permet d'éviter que le tablier 410 ne vienne frotter contre la paroi de séparation verticale 460 lors de l'enroulement ou du déroulement du tablier flottant 410. En effet, si la distance « e » entre la paroi de séparation verticale 460 et le tablier flottant 410 enroulé est trop faible, le tablier 410 peut venir frotter ou se coincer contre la paroi de séparation verticale 460.According to one embodiment of the invention, the covering device 400 comprises a vertical partition 460 in front of the platform 450 and forming a box around the winding axis 470. The opening "O" for the passage of the floating apron 410 can be located at the top of this vertical separation wall 460. The opening O is then positioned vertically. As with the previous embodiments, this opening constitutes a free passage, that is to say not closed off by a valve or a shutter which would be movable between a closed and open position. According to a preferred embodiment, the distance "e" between the vertical separation wall 460 and the floating apron 410 rolled up around the winding axis 470 in the open position (ie when the floating apron 410 is completely rolled up around the axis 470) is at least equal to a predetermined value, for example determined according to the thickness of the floating deck 410. According to one embodiment of the invention, this distance "e" is at least equal to 7 centimeters . This minimum distance between the wall of vertical separation 460 and the rolled up floating apron 410 makes it possible to prevent the apron 410 from rubbing against the vertical separation wall 460 when rolling up or unrolling the floating apron 410. Indeed, if the distance "e" between the vertical separation wall 460 and the rolled up floating apron 410 is too weak, the apron 410 may come to rub or get stuck against the vertical separation wall 460.

Selon un mode de réalisation alternatif de l'invention (non illustré), la paroi de séparation verticale 460 est décalée et avancée par rapport à l'extrémité avant de la plate-forme 450, l'extrémité haute de la paroi de séparation verticale 460 montant jusqu'à la même hauteur que la plate-forme 450. Dans ce cas, l'ouverture O est formée par l'espace horizontal entre l'extrémité avant de la plate-forme 450 et le haut de la paroi de séparation verticale 460. L'ouverture O est alors positionnée horizontalement. De même que pour les modes de réalisation précédents, cette ouverture constitue un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte.According to an alternate embodiment of the invention (not shown), the vertical divider wall 460 is offset and forward relative to the front end of the platform 450, the top end of the vertical divider wall 460 rising to the same height as the platform 450. In this case, the opening O is formed by the horizontal space between the front end of the platform 450 and the top of the vertical partition wall 460 The opening O is then positioned horizontally. As with the previous embodiments, this opening constitutes a free passage, that is to say not closed off by a valve or a shutter which would be movable between a closed and open position.

La figure 5 illustre une vue de profil d'un dispositif de couverture 500 d'un bassin de piscine selon un autre mode de réalisation de l'invention.There figure 5 illustrates a side view of a cover device 500 for a swimming pool basin according to another embodiment of the invention.

Le dispositif de couverture 500 comprend comme le dispositif illustré dans la figure 4 une plate-forme 550 supportée par deux poutrelles 530 et 540, la poutrelle 530 supportant dans cet exemple l'extrémité avant de la plate-forme 550. Un tablier flottant 510 est enroulé autour d'un axe 570. Le mode de réalisation de l'invention illustré dans la figure 5 se distingue du mode de réalisation illustré dans la figure 4 en ce que le dispositif de couverture 500 est intégré dans une cavité située au fond de la piscine, contre la paroi A. Ce mode de réalisation illustré dans la figure 5 ne comprend donc pas de paroi verticale identique à la paroi verticale 460 de la figure 4. De même, selon ce mode de réalisation, l'ouverture O, permettant le passage du tablier 510, est située du côté de l'extrémité avant de la plate-forme 550, sous celle-ci, et débouche horizontalement au fond de la piscine. L'ouverture O peut devoir respecter les contraintes d'une norme, par exemple la norme NF P90-308. L'ouverture O étant un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte, sa largeur peut ainsi être soumise à la même contrainte de valeur maximale que la largeur du jeu entre la paroi A et la plate-forme (« d »).The cover device 500 comprises, like the device illustrated in the figure 4 a platform 550 supported by two beams 530 and 540, the beam 530 in this example supporting the front end of the platform 550. A floating deck 510 is wrapped around a shaft 570. The embodiment of the invention illustrated in the figure 5 differs from the embodiment illustrated in the figure 4 in that the cover device 500 is integrated in a cavity located at the bottom of the swimming pool, against the wall A. This embodiment illustrated in the figure 5 therefore does not include a vertical wall identical to the vertical wall 460 of the figure 4 . Similarly, according to this embodiment, the opening O, allowing the passage of the apron 510, is located on the side of the front end of the platform 550, under the latter, and opens horizontally at the bottom of the swimming pool. . The opening O may have to comply with the constraints of a standard, for example standard NF P90-308. The opening O being a free passage, that is to say not closed off by a valve or a shutter which would be movable between a closed and open position, its width can thus be subjected to the same constraint of maximum value as the width the play between the wall A and the platform (“d”).

Selon un mode de réalisation alternatif de l'invention, la cavité dans laquelle est installé le dispositif de couverture 500 est constituée par une paroi verticale similaire à la paroi verticale 460 de la figure 4, par exemple constituée par un mur en béton. Dit autrement, selon ce mode de réalisation de l'invention, la paroi de séparation verticale 460 est une paroi verticale tel un mur en béton. L'ouverture O est formée par un espace entre l'extrémité avant de la plate-forme 550 et la paroi de séparation verticale, espace par lequel peut passer le tablier flottant 510. L'ouverture O est alors positionnée horizontalement, comme illustré dans la figure 5.According to an alternative embodiment of the invention, the cavity in which the covering device 500 is installed is constituted by a vertical wall similar to the vertical wall 460 of the figure 4 , for example consisting of a concrete wall. In other words, according to this embodiment of the invention, the vertical partition wall 460 is a vertical wall such as a concrete wall. The opening O is formed by a space between the front end of the platform 550 and the vertical partition wall, a space through which the floating apron 510 can pass. The opening O is then positioned horizontally, as illustrated in the figure 5 .

Selon un mode de réalisation de l'invention, la plate-forme 550 et l'extrémité haute de la paroi verticale affleurent à un même niveau. Selon un mode de réalisation de l'invention, la plate-forme 550 est plus basse que l'extrémité haute de la paroi verticale.According to one embodiment of the invention, the platform 550 and the upper end of the vertical wall are flush with the same level. According to one embodiment of the invention, the platform 550 is lower than the upper end of the vertical wall.

Selon un mode de réalisation de l'invention, le dispositif de couverture comprend une paroi de séparation verticale disposée du côté de l'extrémité avant de la plate-forme, la plate-forme et la paroi de séparation verticale formant un caisson autour de l'axe d'enroulement. La paroi de séparation verticale est positionnée à l'avant de l'extrémité avant de la plate-forme, l'ouverture O pour le passage du tablier flottant étant formée par un espace horizontal entre l'extrémité avant de la plate-forme et la paroi de séparation verticale. De même que pour les modes de réalisation précédents, cette ouverture constitue un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte.According to one embodiment of the invention, the cover device comprises a vertical separation wall arranged on the side of the front end of the platform, the platform and the vertical separation wall forming a box around the winding axis. The vertical partition wall is positioned forward of the front end of the platform, the opening O for the passage of the floating apron being formed by a horizontal space between the front end of the platform and the vertical dividing wall. As with the previous embodiments, this opening constitutes a free passage, that is to say not closed off by a valve or a shutter which would be movable between a closed and open position.

Les figures 6 à 11 illustrent différentes positions d'un dispositif de couverture 600 pour un bassin d'une piscine selon l'invention entre la position ouverte représentée dans la figure 6 et la position fermée représentée dans la figure 11. Les figures 6 à 11 représentent donc un même dispositif de couverture 600 dans différentes positions, entre une position ouverte et une position fermée. Ces figures peuvent être lues dans un sens ou dans un autre selon que le dispositif de couverture passe de la position ouverte à la position fermée (sens de lecture de la figure 6 à la figure 11) ou bien au contraire de la position fermée à la position ouverte (sens de lecture de la figure 11 à la figure 6). Le dispositif de couverture 600 illustré est par exemple le dispositif de couverture 400 précédemment décrit.THE figures 6 to 11 illustrate different positions of a cover device 600 for a basin of a swimming pool according to the invention between the open position represented in the figure 6 and the closed position represented in the figure 11 . THE figures 6 to 11 therefore represent the same covering device 600 in different positions, between an open position and a closed position. These figures can be read in one direction or another depending on whether the covering device passes from the open position to the closed position (reading direction of the figure 6 to the figure 11 ) or on the contrary from the closed position to the open position (reading direction of the figure 11 to the figure 6 ). The cover device 600 illustrated is for example the cover device 400 previously described.

La figure 6 illustre des vues de profil et de haut d'un dispositif de couverture 600 d'un bassin de piscine, comprenant une paroi A et une paroi opposée B délimitant une longueur de la piscine, selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une position ouverte.There figure 6 illustrates side and top views of a covering device 600 for a swimming pool basin, comprising a wall A and an opposite wall B delimiting a length of the swimming pool, according to one embodiment of the invention, the device cover 600 being in an open position.

Le dispositif de couverture 600 est ici représenté dans la position ouverte, c'est-à-dire que le tablier 610 est totalement enroulé autour d'un axe 670 et que l'accès au bassin est libre. Avantageusement, dans la position ouverte, l'extrémité libre du tablier flottant 610 est située du côté de l'extrémité avant de la plate-forme 650, ici sous l'extrémité avant de la plate-forme 650, possiblement sous un moyen de guidage 680. Le sens d'enroulement/déroulement du tablier 610 autour de l'axe 670 est choisi de tel manière que le déroulement du tablier 610 se fasse de façon que l'extrémité libre E du tablier 610 remonte du côté de l'ouverture O, ici située sous l'extrémité avant de la plate-forme 650, possiblement guidé par le moyen de guidage 680. Dit autrement, le sens de déroulement de l'axe 670 correspond au sens de rotation F précédemment défini.The covering device 600 is represented here in the open position, that is to say that the apron 610 is completely rolled up around an axis 670 and that access to the basin is free. Advantageously, in the open position, the free end of the floating deck 610 is located on the side of the front end of the platform 650, here under the front end of the platform 650, possibly under a guide means 680. The winding direction / unwinding of the apron 610 around the axis 670 is chosen such that the unwinding of the apron 610 is done so that the free end E of the apron 610 rises on the side of the opening O , here located under the front end of the platform 650, possibly guided by the guide means 680. In other words, the direction of unwinding of the axis 670 corresponds to the direction of rotation F previously defined.

Une zone dans laquelle la largeur du bassin est inférieure à la largeur du reste du bassin du fait de la présence des arrondis aux angles de la paroi verticale A avec les autres parois verticales adjacentes (ou de tout autre forme et/ou excroissance) est matérialisée par des pointillés. Cette zone s'étend sur une distance « a ».A zone in which the width of the pool is less than the width of the rest of the pool due to the presence of rounded corners of the vertical wall A with the other adjacent vertical walls (or any other shape and/or protrusion) is materialized by dotted lines. This zone extends over a distance “a”.

Concernant la vue de haut de la piscine (en bas sur la figure 6 et suivantes), la surface du bassin recouverte par le tablier flottant 610 est matérialisée par des hachures. Dans la figure 6, le dispositif de couverture 600 étant dans la position ouverte, le tablier flottant 610 est entièrement enroulé. L'accès au bassin est donc libre.Concerning the top view of the swimming pool (down on the figure 6 and following), the surface of the basin covered by the floating apron 610 is materialized by hatching. In the figure 6 , the covering device 600 being in the open position, the floating apron 610 is completely rolled up. Access to the pool is therefore free.

Selon un mode de réalisation de l'invention, le dispositif de couverture 600 comprend une paroi de séparation verticale 660. La paroi de séparation verticale 660 est disposée du côté de l'extrémité avant de la plate-forme 650, la plate-forme 650 et la paroi de séparation verticale 660 formant un caisson autour de l'axe d'enroulement 670. La paroi de séparation verticale 660 peut comprendre l'ouverture O pour le passage du tablier flottant 610. De même que pour les modes de réalisation précédents, cette ouverture constitue un passage libre, c'est-à-dire non obturé par un clapet ou un volet qui serait mobile entre une position fermée et ouverte. L'ouverture O est de préférence située en haut de la paroi de séparation verticale 660, mais elle peut être située à n'importe quelle hauteur de la paroi de séparation verticale 660. Selon un mode de réalisation, l'ouverture O est située au bas de de la paroi de séparation verticale 660, au niveau du fond du bassin.According to one embodiment of the invention, the covering device 600 comprises a vertical partition wall 660. The vertical partition wall 660 is arranged on the side of the front end of the platform 650, the platform 650 and the vertical separation wall 660 forming a box around the winding axis 670. The vertical separation wall 660 may include the opening O for the passage of the floating apron 610. As with the previous embodiments, this opening constitutes a free passage, that is to say not closed off by a valve or a shutter which would be movable between a closed and open position. The opening O is preferably located at the top of the vertical partition wall 660, but it can be located at any height of the vertical partition wall 660. According to one embodiment, the opening O is located at the bottom of the vertical separation wall 660, at the bottom of the basin.

La figure 7 illustre des vues de profil et de haut du dispositif de couverture 600 d'un bassin de piscine selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une première position intermédiaire.There figure 7 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a first intermediate position.

La figure 7 représente une situation dans laquelle le tablier 610 de la figure 6 a été en partie déroulé, c'est-à-dire en début de fermeture du bassin. En arrivant à la surface, l'extrémité libre E du tablier 610 bascule dans la direction de la paroi B, par exemple au moyen d'un lest placé dans l'extrémité libre E du tablier 610 (ou du fait de la géométrie de ladite extrémité libre E). Au fur et à mesure que le tablier est déroulé par l'axe 670 tournant dans le sens de rotation F, le tablier 610 progresse à la surface du bassin vers la paroi B, recouvrant progressivement la surface du bassin, comme illustré par des hachures sur la vue de dessus du bassin de la piscine.There figure 7 represents a situation in which the apron 610 of the figure 6 was partly unrolled, i.e. at the beginning of the closing of the basin. Arriving at the surface, the free end E of the deck 610 tilts in the direction of the wall B, for example by means of a ballast placed in the free end E of the deck 610 (or due to the geometry of said free end E). As the apron is unrolled by the axis 670 rotating in the direction of rotation F, the apron 610 progresses on the surface of the basin towards the wall B, gradually covering the surface of the basin, as illustrated by hatching on the top view of the pool basin.

La figure 8 illustre des vues de profil et de haut du dispositif de couverture 600 d'un bassin de piscine selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une deuxième position intermédiaire.There figure 8 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a second intermediate position.

La figure 8 représente une situation dans laquelle le tablier 610 est arrivée en butée contre la paroi B. L'extrémité libre E est en butée contre la paroi B. A partir de ce moment, lors du déroulement du tablier 610 pour fermer le bassin, le tablier 610 se déroule vers la paroi A : la partie encore immergée du tablier 610 vient se dérouler progressivement à la surface du bassin en direction de la paroi A.There figure 8 represents a situation in which the apron 610 has come into abutment against the wall B. The free end E is in abutment against the wall B. From this moment, during the unwinding of the apron 610 to close the basin, the apron 610 unfolds towards wall A: the still submerged part of deck 610 gradually unfolds on the surface of the pool towards wall A.

La figure 9 illustre des vues de profil et de haut du dispositif de couverture 600 d'un bassin de piscine selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une troisième position intermédiaire.There figure 9 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a third intermediate position.

La figure 9 représente une situation dans laquelle le tablier 610 est arrivé en butée contre la paroi B et dans laquelle le tablier 610 s'est déroulé partiellement vers la paroi A. La partie encore immergée du tablier 610 est venue se dérouler progressivement à la surface du bassin, en direction de la paroi A. L'extrémité G du tablier 610 rattachée à l'axe 670 au moyen par exemple de sangles 690 est ici représentée comme étant sortie du caisson du dispositif de couverture 600.There figure 9 represents a situation in which the apron 610 has come into abutment against the wall B and in which the apron 610 has partially unrolled towards the wall A. The still submerged part of the apron 610 has gradually unrolled on the surface of the pool, towards wall A. End G of the apron 610 attached to the axis 670 by means for example of straps 690 is here represented as having come out of the box of the covering device 600.

Un cercle de courbure C du tablier flottant 610 est représenté par des pointillés dans la figure 9. Le rayon de courbure du tablier flottant 610 correspond au rayon du cercle de courbure C. La hauteur « h » est déterminée de façon que le tablier flottant 610 puisse former une boucle au-dessus de la plate-forme, la hauteur « h » doit donc être supérieure ou égale au diamètre du cercle de courbure C, soit deux fois le rayon de courbure du tablier flottant.A circle of curvature C of the floating apron 610 is represented by dotted lines in the figure 9 . The radius of curvature of the floating apron 610 corresponds to the radius of the circle of curvature C. The height "h" is determined so that the floating apron 610 can form a loop above the platform, the height "h" must therefore be greater than or equal to the diameter of the circle of curvature C, i.e. twice the radius of curvature of the floating deck.

Si la hauteur d'eau « h » au-dessus de la plate-forme 650 n'est pas suffisante, alors la partie immergée du tablier flottant 610 n'arrive pas à se déployer correctement seule et reste coincée sous la partie du tablier flottant 610 déjà déroulée en surface. Le dispositif de couverture 600 ne peut alors couvrir entièrement la surface du bassin sans une action supplémentaire. Il est alors possible pour un utilisateur de finir de déployer le tablier flottant 610 « à la main », par exemple en tirant dessus et/ou en aidant le déroulement du tablier en le soulevant dans la dernière phase du déroulement.If the water height "h" above the platform 650 is not sufficient, then the submerged part of the floating apron 610 cannot deploy correctly on its own and remains stuck under the part of the floating apron 610 already unrolled on the surface. The covering device 600 cannot then entirely cover the surface of the basin without an additional action. It is then possible for a user to finish deploying the floating apron 610 “by hand”, for example by pulling on it and/or by helping the unrolling of the apron by lifting it in the last phase of unrolling.

Selon un mode de réalisation de l'invention, et selon la flottabilité, taille et/ou rigidité des lattes constituant le tablier flottant 610, la hauteur « h » peut être légèrement inférieure au diamètre de courbure du tablier flottant, le tablier flottant 610 pouvant dépasser marginalement au-dessus de la surface de l'eau lors de l'enroulement/déroulement au-dessus de la plate-forme 650.According to one embodiment of the invention, and depending on the buoyancy, size and/or rigidity of the slats constituting the floating deck 610, the height "h" may be slightly less than the diameter of curvature of the floating deck, the floating deck 610 being able to protrude marginally above the surface of the water when winding/unwinding above the 650 platform.

La figure 10 illustre des vues de profil et de haut du dispositif de couverture 600 d'un bassin de piscine selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une quatrième position intermédiaire.There figure 10 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a fourth intermediate position.

La figure 10 représente une situation dans laquelle le tablier flottant 610 est arrivé en butée contre la paroi B et dans laquelle le tablier 610 s'est déroulé vers la paroi A. La partie encore immergée du tablier 610 est venue se dérouler progressivement à la surface du bassin vers la paroi A. L'extrémité G du tablier 610 rattachée à l'axe 470, au moyen par exemple de sangles, est ici représentée comme étant sortie du caisson du dispositif de couverture 600 et s'approchant de la paroi A, le tablier 610 se positionnant de lui-même du fait de sa flottabilité à la surface du bassin.There figure 10 represents a situation in which the floating apron 610 has come into abutment against the wall B and in which the apron 610 has unrolled towards the wall A. The still submerged part of the apron 610 has gradually unrolled on the surface of the basin the wall A. The end G of the apron 610 attached to the axis 470, by means for example of straps, is here represented as having come out of the box of the covering device 600 and approaching the wall A, the apron 610 positioning itself by virtue of its buoyancy on the surface of the pool.

La figure 11 illustre des vues de profil et de haut du dispositif de couverture 600 d'un bassin de piscine selon un mode de réalisation de l'invention, le dispositif de couverture 600 étant dans une position fermée.There figure 11 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a closed position.

La figure 11 représente une situation dans laquelle le tablier 610 est arrivé en butée contre la paroi B et contre la paroi A. Le tablier 610 recouvre totalement la surface du bassin de la piscine, le dispositif de couverture 600 est dans sa position fermée. L'extrémité E du tablier flottant 610 est en butée contre la paroi B et l'extrémité G du tablier flottant 610 est en butée contre la paroi A.There figure 11 represents a situation in which the apron 610 has come into abutment against the wall B and against the wall A. The apron 610 completely covers the surface of the pool basin, the cover device 600 is in its closed position. The end E of the floating apron 610 abuts against the wall B and the end G of the floating apron 610 abuts against the wall A.

Le dispositif de couverture 600 peut revenir dans sa position ouverte, illustrée dans la figure 6, en mettant en rotation l'axe 670 dans l'autre sens que le sens de rotation F afin d'enrouler le tablier 610 autour de l'axe 670. Lors de l'enroulement vers la position ouverte, le tablier 610 prend les différentes positions intermédiaires illustrées dans les figures 10 à 7, dans l'ordre inverse de l'ordre précédemment décrit pour le déroulement du tablier 610 vers la position fermée.The cover device 600 can return to its open position, illustrated in the figure 6 , by rotating the axis 670 in the other direction than the direction of rotation F in order to wind the apron 610 around the axis 670. When winding towards the open position, the apron 610 takes the different intermediate positions illustrated in the figures 10 to 7 , in the reverse order of the order previously described for the unwinding of the apron 610 towards the closed position.

La forme de l'extrémité libre E du tablier flottant 610 est prévue pour venir en butée contre la paroi B. De même, La forme de l'extrémité G du tablier flottant 610 est prévue pour venir en butée contre la paroi A.The shape of the free end E of the floating deck 610 is designed to come into abutment against the wall B. Similarly, the shape of the end G of the floating deck 610 is designed to come into abutment against the wall A.
