Description

Dispositif de fond mobile pour bassin  Basin moving device for pond
La présente invention a pour objet un dispositif de fond mobile pour bassin rempli d'eau, telle qu'une piscine d'agrément ou tout autre ouvrage dans lequel on veut pouvoir recouvrir la surface de l'eau d'un plancher amovible . The present invention relates to a movable bottom device for a basin filled with water, such as a pleasure pool or any other work in which it is desired to cover the surface of the water with a removable floor.
Le domaine technique est la construction de planchers ou dispositifs de couverture constitués d'éléments rigides pour bassins tel que piscines.  The technical field is the construction of floors or covering devices consisting of rigid elements for basins such as swimming pools.
On connaît divers équipements qui permettent de recouvrir la surface d'un bassin pour, d'une part, la protéger des salissures et/ou l'isoler thermiquement , et d'autre part, assurer la sécurité pour éviter la chute de personnes et surtout d'enfants dans l'eau quand le bassin n'est pas utilisé et qu'il n'y a personne pour en surveiller l'accès.  We know various equipment that cover the surface of a pool to, firstly, protect it from dirt and / or isolate it thermally, and secondly, provide security to prevent the fall of people and especially children in the water when the pool is not in use and there is no one to monitor access.
Ainsi, il existe :  Thus, there are:
des rideaux constitués de lames rigides articulées entre elles et remplies de matériau de flottaison que l'on stocke à une extrémité du bassin et que l'on déroule à partir d'un tambour tel que décrit dans la demande de brevet FR 2 948 396,  curtains consisting of rigid blades hinged together and filled with flotation material which is stored at one end of the basin and which is unrolled from a drum as described in the patent application FR 2 948 396,
- des véritables toitures constituées d'éléments superposables pour le stockage et qui sont placés côte à côte pour recouvrir le bassin, comme décrit dans les demandes de brevet FR 2 939 466 ou FR 2 935 406,  real roofs consisting of stackable elements for storage which are placed side by side to cover the basin, as described in patent applications FR 2 939 466 or FR 2 935 406,
des planchers mobiles qui sont soit immergés dans le fond du bassin pour leur stockage et soulevés pour venir jusqu'en surface à l'aide de câbles ou chaînes entraînés par des treuils, tel que décrit dans la demande de brevet FR 2 942 636, soit stockés en surface sur le côté du bassin et déplaçables latéralement sur rail pour recouvrir ce bassin. movable floors that are either immersed in the bottom of the basin for storage and lifted to the surface using cables or chains driven by winches, as described in the patent application FR 2 942 636, or stored on the surface on the side of the pool and laterally movable rail to cover this basin.
Tous ces divers équipements permettent certes de répondre aux objectifs évoqués précédemment mais avec chacun au moins un ou plusieurs inconvénients majeurs :  All these various equipment can certainly meet the objectives mentioned above but with each at least one or more major disadvantages:
- pour le premier, la sécurité n'est pas complète du fait de la déformabilité des rideaux et il n'est pas possible de pouvoir marcher normalement et à plusieurs personnes sur ceux-ci ; l'isolation est limitée car on ne peut pas avoir des lames trop épaisses qui gêneraient le stockage et la manipulation ; et quand ils ne sont pas utilisés, les rideaux enroulés, même de faible épaisseur, représentent des volumes encombrants qui occupent une partie de la plage entourant les bassins,  - For the first, the security is not complete due to the deformability of the curtains and it is not possible to walk normally and several people on them; insulation is limited because you can not have too thick blades that would interfere with storage and handling; and when they are not used, the rolled curtains, even of small thickness, represent bulky volumes which occupy a part of the beach surrounding the basins,
- pour les deuxièmes, on retrouve certains inconvénients des premiers cités ci-dessus, tels que de ne pas pouvoir marcher normalement dessus et l'encombrement du stockage, ainsi que la manipulation qui est soit manuelle et donc délicate, soit mécanique et alors complexe,  - For the second, we find some disadvantages of the first mentioned above, such as not being able to walk normally on and storage space, and the manipulation that is either manual and therefore delicate, or mechanical and then complex,
pour les troisièmes, certains inconvénients précédents sont certes résolus mais en contrepartie, ces équipements nécessitent la mise en œuvre de mécanique complexe, coûteuse et nécessitant des travaux importants d'installation, et, soit pour les planchers immergés, ils peuvent ne pas être compatibles avec le traitement de l'eau, soit pour les planchers mobiles latéralement en surface, ils aggravent même le problème de l'encombrement pour leur stockage.  for the third, some of the previous disadvantages have been solved but in return, these equipment require the implementation of complex mechanics, expensive and require significant installation work, and, either for submerged floors, they may not be compatible with water treatment, either for floors moving laterally on the surface, they even worsen the problem of congestion for their storage.
Ainsi, pour satisfaire aux inconvénients ci- dessus, un quatrième type d'équipement, sur le concept du troisième ci-dessus dans la version immergeable, propose de remplacer le système mécanique de relevage par des ballasts intégrés au plancher mobile, tel que décrit dans la demande de brevet FR 2 945 063 : cependant, la hauteur totale de la structure plancher-ballast est alors très épaisse, ce qui diminue la profondeur utile des bassins quand ils sont posés au fond (ou il faut augmenter la profondeur initiale du bassin) ; de plus, la difficulté de contrôle de la quantité d'air injecté dans les compartiments des ballasts rend leur stabilité et leur maintien horizontal incertains, nécessitant des dispositifs de contrôle et de guidage complexes ; et ces équipements comportent des systèmes et des conduites flexibles d'alimentation pour amener et distribuer l'air à l'intérieur des compartiments de ballasts, ce qui en complique la réalisation et la mise en place. Thus, to satisfy the above drawbacks, a fourth type of equipment, on the concept of the third above in the immersible version, proposes to replace the mechanical lift system with ballasts integrated in the movable floor, as described in the patent application FR 2 945 063: however, the total height of the floor-ballast structure is then very thick, which reduces the useful depth basins when they are placed at the bottom (or increase the initial depth of the basin); moreover, the difficulty of controlling the quantity of air injected into the ballast compartments renders their stability and their horizontal maintenance uncertain, requiring complex control and guidance devices; and these devices include flexible supply systems and lines for supplying and distributing the air inside the ballast compartments, which complicates the construction and installation.
Le problème posé est alors, dans le cadre du concept de planchers immergeables et ballastés, de réduire la hauteur totale de la structure portant ces planchers, d'augmenter leur stabilité lors des phases d'émersion par injection d'air et d'immersion par vidange de cet air, et de permettre une fabrication et une installation simple.  The problem posed is then, in the context of the concept of immersible and ballasted floors, to reduce the total height of the structure carrying these floors, to increase their stability during the phases of emergence by air injection and immersion by drain of this air, and allow a simple manufacture and installation.
Une solution au problème posé est un dispositif de fond mobile pour bassin rempli d'eau suivant le concept général défini précédemment, à savoir comportant une structure porteuse d'un plancher épousant au moins en partie la forme de la surface du bassin et supportée par au moins un ballast, lequel ballast étant apte à déplacer le dispositif entre au moins une position immergée dans laquelle le dispositif repose sur le fond du bassin et une position dans laquelle ledit plancher est émergé et recouvre au moins ladite partie de la surface de l'eau : selon l'invention, le au moins ballast est en forme de jupe ouverte à sa partie inférieure et le dispositif comporte au moins une bouche d'arrivée d'air disposée au fond du bassin et à la verticale de l'ouverture de la jupe du ballast, laquelle jupe est de préférence souple et apte à se plier quand le dispositif repose sur le fond du bassin. A solution to the problem posed is a movable bottom device for a basin filled with water according to the general concept defined above, namely having a structure carrying a floor at least partially matching the shape of the basin surface and supported by at least one ballast, which ballast is capable of moving the device between at least one immersed position in which the device rests on the bottom of the basin and a position in which said floor has emerged and covers at least said part of the surface of the water : according to the invention, the at least one ballast is open skirt-shaped at its lower part and the device comprises at least one air inlet mouth disposed at the bottom of the basin and vertically to the opening of the skirt of the ballast, which skirt is preferably flexible and able to bend when the device rests on the bottom of the basin.
Dans un mode préférentiel de réalisation pour améliorer la stabilité d'ensemble, le dispositif suivant l'invention comporte au moins deux ballasts indépendants et au moins deux bouches d'arrivée d'air, et chaque ballast comporte une valve d'évacuation de l'air à sa partie supérieure.  In a preferred embodiment for improving the overall stability, the device according to the invention comprises at least two independent ballasts and at least two air intake vents, and each ballast comprises a discharge valve of the air at the top.
Le résultat est un nouveau dispositif de fond mobile pour bassin qui répond au problème posé sans avoir les inconvénients cités précédemment pour tous les dispositifs existants : en effet, la forme, en jupe ouverte vers le bas, des ballasts permet de réduire la hauteur de la structure, même si, bien sûr, il est nécessaire que le volume de tels ballasts, en particulier quand il s'agit d'une jupe souple qui se replie alors quand la structure est posée sur le fond du bassin, doit permettre de les remplir suffisamment d'air pour soulever l'ensemble depuis cette position ; et au fur et à mesure que la structure remonte vers la surface, les jupes, quand elles sont souples, se déplient, et la poussée de relevage ainsi que la stabilité augmentent. De plus, l'installation des bouches d'arrivée d'air sur le fond du bassin évite toute connexion et alimentation, tel que par flexibles, du fond mobile : l'installation et la mise en œuvre de celui-ci en sont ainsi simplifiées. La description et les figures ci-jointes donnent un exemple de la réalisation du dispositif suivant l'invention, dont les avantages évoqués ci-dessus en prouvent l'intérêt et dont d'autres modes de réalisation sont cependant possibles dans le cadre de la portée de la présente invention. The result is a new mobile bottom basin device that responds to the problem without having the disadvantages mentioned above for all existing devices: indeed, the shape, in open skirt down, ballasts can reduce the height of the structure, although, of course, it is necessary that the volume of such ballasts, especially when it comes to a flexible skirt that folds so when the structure is placed on the bottom of the basin, must allow to fill them enough air to lift the assembly from this position; and as the structure rises to the surface, the skirts, when they are flexible, unfold, and the lifting thrust and stability increase. In addition, the installation of air inlet vents on the bottom of the basin avoids any connection and supply, such as flexible, mobile bottom: installation and implementation of it are thus simplified . The description and the accompanying figures give an example of the embodiment of the device according to the invention, the advantages of which are evidenced by the above-mentioned advantages and which other embodiments are nevertheless possible within the scope of the scope. of the present invention.

Comme décrit précédemment, le dispositif de fond mobile 19 pour bassin 10 rempli d'eau 8 comporte une structure 11 porteuse d'un plancher 1 épousant au moins en partie la forme de la surface du bassin et supportée par au moins un ballast 2, lequel ballast étant apte à déplacer le dispositif 19 entre au moins une position immergée dans lequel le dispositif repose sur le fond 21 du bassin, comme représenté sur la figure 1, et une position dans laquelle ledit plancher 1 est émergé et recouvre au moins ladite partie de la surface 9 de l'eau, comme représenté sur la figure 3, sachant que, dans les figures jointes, le plancher épouse en fait la totalité de la surface du bassin et dans d'autres modes de réalisation pour lesquels la sécurité n'est pas nécessaire pour la totalité de la surface, il pourrait ne recouvrir qu'une partie de celle-ci. As previously described, the movable bottom device 19 for basin 10 filled with water 8 comprises a structure 11 carrying a floor 1 at least partially matching the shape of the basin surface and supported by at least one ballast 2, which ballast being able to move the device 19 between at least one submerged position in which the device rests on the bottom 21 of the basin, as shown in FIG. 1, and a position in which said floor 1 has emerged and covers at least said portion of the surface 9 of the water, as shown in FIG. 3, knowing that, in the accompanying figures, the floor in fact marries the whole of the basin surface and in other embodiments for which safety is not necessary for the entire surface, it could cover only part of it.
Le au moins ballast 2 est en forme de jupe 12 ouverte à sa partie inférieure et le dispositif comporte au moins une bouche 3 d'arrivée d'air disposée au fond 21 du bassin et à la verticale de l'ouverture de la jupe du ballast 2.  The at least ballast 2 is in the form of a skirt 12 open at its bottom and the device comprises at least one air inlet mouth 3 disposed at the bottom 21 of the basin and at the vertical of the opening of the skirt of the ballast 2.
De préférence, le dispositif comporte au moins deux ballasts indépendants 2 et au moins deux bouches 3 d'arrivée d'air, comme représenté sur les figures qui sont des vues en coupe verticale dans l'une des dimensions du bassin, et cette répartition peut être également reproduite dans la dimension perpendiculaire à celle représentée, le dispositif comportant alors au moins quatre ballasts indépendants disposés en carré ou rectangle ; et, si le bassin est plus long que large, on peut disposer trois rangées de deux ballasts dans le sens de la longueur ; et pour avoir une stabilité encore plus grande pour des bassins de dimensions importantes, il peut être disposé trois rangées de trois ballasts etc., sachant qu'il faut alors au moins une bouche 3 d'arrivée d'air en-dessous de chaque ballast.  Preferably, the device comprises at least two independent ballasts 2 and at least two air intake ports 3, as shown in the figures which are vertical sectional views in one of the dimensions of the basin, and this distribution can also be reproduced in the dimension perpendicular to that shown, the device then comprising at least four independent ballasts arranged in a square or rectangle; and if the basin is longer than wide, three rows of two ballasts may be arranged lengthwise; and to have an even greater stability for tanks of large dimensions, it can be arranged three rows of three ballasts etc., knowing that then it takes at least one air inlet mouth 3 below each ballast .
Les bouches d' arrivée d' air 3 peuvent être simplement posées sur le fond du bassin et alimentées par des conduites d' air 4 qui peuvent être soit posées facilement le long du fond du bassin pour les bassins existants, soit intégrées dans ceux-ci pour les bassins en construction, jusqu'à un local technique 7 construit éventuellement assez loin du bassin pour dégager les plages entourant celui-ci, lequel local technique contient au moins une pompe à air 6 qui alimente lesdites conduites 4 à travers des robinets de régulation 5. The air intake vents 3 can be simply placed on the bottom of the pool and fed by air ducts 4 which can either be easily placed along the bottom of the pool for the existing basins, or integrated into them. for basins under construction, up to a technical room 7 built possibly far enough from the basin to clear the beaches surrounding it, which technical room contains at least one air pump 6 which feeds said lines 4 through regulating valves 5.
De préférence, la jupe 12 des ballasts est souple et apte à se plier quand le dispositif repose sur le fond 21 du bassin, comme représenté sur la figure 1 et ces jupes 12 comportent chacune au moins un lest 15 disposé autour de leur ouverture inférieure, soit d'une manière continue, soit discontinue ; lequel lest 15 est apte à maintenir dépliée la jupe 12 quand le dispositif 19 est soulevé du fond, comme représenté sur les figures 2 et 3. Ces jupes lestées empêchent également ou tout au moins réduisent les pertes d'air s'il y a inclinaison (tangage ou roulis) de la structure, comme représenté sur la figure 5 ; cette figure illustre également la stabilité que permet la disposition de plusieurs ballasts indépendants et à volume d'air variable 20, côte à côte.  Preferably, the skirt 12 of the ballasts is flexible and able to bend when the device rests on the bottom 21 of the basin, as shown in Figure 1 and these skirts 12 each comprise at least one ballast 15 disposed around their lower opening, either continuously or discontinuously; which ballast 15 is able to keep unfolded the skirt 12 when the device 19 is lifted from the bottom, as shown in Figures 2 and 3. These weighted skirts also prevent or at least reduce air loss if there is inclination (pitch or roll) of the structure, as shown in Figure 5; this figure also illustrates the stability that allows the provision of several independent ballasts and variable air volume 20, side by side.
Pour permettre un meilleur équilibrage de la structure 11 par un remplissage homogène des ballasts 2 et donc limiter le risque de tangage et de roulis, chaque ballast 2 comporte une valve 13 d'évacuation de l'air à sa partie supérieure, comme représenté sur la figure 2. Ainsi, si l'un des ballasts, comme celui 2i représenté est plus rempli d'air 20i que celui 22 du fait par exemple d'une mauvaise distribution de l'air, la jupe 12i du premier va se gonfler davantage que la jupe 122 du second et l'air contenu 20i dans le ballast 2i s'évacuera plus rapidement que dans l'autre ballast 22 et rétablira progressivement l'équilibre entre les différents ballasts avec une meilleure répartition de l'air. To allow a better balancing of the structure 11 by a homogeneous filling ballasts 2 and thus limit the risk of pitching and rolling, each ballast 2 comprises a valve 13 for evacuation of air at its upper part, as shown in FIG. FIG. 2. Thus, if one of the ballasts, such as the one shown, is more filled with air 20i than the one 2 2 because of, for example, a bad distribution of air, the skirt 12i of the first one will inflate further. that the skirt 12 2 of the second and the air content 20i in the ballast 2i will evacuate faster than in the other ballast 2 2 and gradually restore the balance between the different ballasts with a better distribution of air.
Pour améliorer cette répartition, les valves 13 peuvent être pilotées en fermeture et en ouverture, mais ce qui compliquerait l'installation et la mise en œuvre. Aussi, pour améliorer la stabilité et le maintien en position quasi horizontale du plancher 1, le dispositif de fond mobile 19 comporte des rouleaux 16, 17 de guidage latéral solidaires de la structure 11 et aptes à venir en appui contre les parois 22 verticales du bassin 10, comme représenté sur la figure 4. To improve this distribution, the valves 13 can be controlled closing and opening, but this would complicate the installation and implementation. Also, to improve the stability and maintenance in the almost horizontal position of the floor 1, the movable bottom device 19 comprises rollers 16, 17 of lateral guide integral with the structure 11 and able to bear against the vertical walls 22 of the basin 10, as shown in FIG. 4.
De plus, si certains rouleaux 16 sont fixés au niveau de la structure proche du plancher 1, d'autres 17 sont portés par des bras supports 18 articulés qui se déplient quand le dispositif est soulevé du fond et qui permettent d'éviter que l'ensemble du dispositif de fond mobile 19 puisse s'incliner d'une valeur trop importante, le temps que le système d'auto-équilibrage de l'air dans les ballasts par les vannes 13 permette d'assurer le maintien de la structure la plus horizontale possible.  In addition, if some rollers 16 are fixed at the level of the structure close to the floor 1, others 17 are carried by articulated support arms 18 which unfold when the device is lifted from the bottom and which make it possible to prevent the all of the movable bottom device 19 can be tilted too much, the time that the self-balancing system of the air in the ballasts by the valves 13 can ensure the maintenance of the structure the more horizontal possible.
Par ailleurs, des verrous 14 mobiles sont aptes à être ouverts en périphérie de la structure 11 porteuse et à solidariser ainsi celle-ci avec les parois latérales 22 verticales du bassin, quand le dispositif de fond mobile 19 est arrivé en position haute flottante à la surface 9 de l'eau 8 du bassin 10 ; le dispositif est alors pris en charge et supporté par ces verrous 14, l'arrivée d'air pouvant être arrêtée, et le plancher peut recevoir des personnes en toute sécurité.  Moreover, movable latches 14 are able to be open at the periphery of the carrier structure 11 and thus to join it with the vertical side walls 22 of the basin, when the movable bottom device 19 has arrived in floating high position at the surface 9 of water 8 of basin 10; the device is then supported and supported by these latches 14, the air inlet can be stopped, and the floor can receive people safely.
Le présent dispositif suivant l'invention est ainsi tel qu' il permet de procéder au recouvrement de la surface d'un bassin 10 rempli d'eau 8 par le dispositif de fond mobile 19, tel que décrit précédemment, et tel que :  The present device according to the invention is thus such that it enables the surface of a basin 10 filled with water 8 to be covered by the mobile bottom device 19, as previously described, and such that:
- on dispose au moins une bouche 3 d'arrivée d'air au fond 21 du bassin 10 et ladite structure porteuse 11 repose sur ce fond 21, on réalise le ballast 2 en forme de cloche ouverte vers le bas et on dispose cette ouverture au- dessus de la bouche 3 d'arrivée d'air, at least one air inlet mouth 3 is provided at the bottom 21 of the basin 10 and said support structure 11 rests on this bottom 21, the bell-shaped ballast 2 is made to open downwards and this opening is placed above the air intake opening 3,
- on envoie de l'air par la bouche 3 et on remplit ainsi progressivement le ballast 2 d'air qui en chasse l'eau et quand la quantité d'air est suffisante, la structure 11 décolle du fond 21 et remonte vers la surface 9,  - Air is sent through the mouth 3 and thus progressively fills the ballast 2 with air that flushes water and when the amount of air is sufficient, the structure 11 off the bottom 21 and back to the surface 9
on dispose préférentiellement d'au moins deux ballasts indépendants sur la structure 11 porteuse et d'au moins deux bouches d'air sur le fond du bassin 21, on laisse échapper de l'air à la partie supérieure de chaque ballast 2 par une valve 13,  preferably at least two independent ballasts are provided on the carrier structure 11 and at least two air vents on the bottom of the tank 21, air is let out at the top of each ballast 2 by a valve 13
- quand le dispositif arrive en surface 9 de l'eau 8 du bassin 10, on immobilise et on verrouille latéralement la structure 11 par des verrous 14 mobiles aptes à s'ouvrir en périphérie de la structure 11 porteuse et à solidariser ainsi celle-ci avec les parois latérales 22 du bassin,  - When the device arrives at the surface 9 of the water 8 of the basin 10, the structure 11 is immobilized and laterally locked by means of movable latches 14 able to open on the periphery of the carrier structure 11 and thus to secure it with the side walls 22 of the basin,
- on arrête alors l'alimentation en air des bouches d'alimentation 3.  the air supply of the supply mouths 3 is then stopped.
