Fond mobile pour piscine  Mobile pool floor
L' invention concerne une structure générale de fond mobile destiné à équiper un bassin de piscine pour être placé soit dans une position inférieure dans laquelle il est au fond du bassin afin de permettre à des personnes de se baigner, soit dans une position supérieure dans la¬ quelle couvre le bassin afin de constituer une protection contre la noyade de personnes évoluant aux abords de la piscine . The invention relates to a general movable floor structure for equipping a swimming pool basin to be placed either in a lower position in which it is at the bottom of the pool to allow people to bathe, or in a higher position in the pool. ¬ What covers the basin to provide protection against drowning people moving around the pool.
ARRIERE PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
Un tel système de fond mobile permet de sécu¬ riser une piscine pour éviter notamment qu'un enfant ne tombe dedans par inadvertance, sans devoir recourir à une barrière grillagée entourant le bassin. Such a movable floor system allows secu ¬ riser including a pool to prevent a child from falling into it inadvertently without requiring a wire fence surrounding the pool.
Un tel fond mobile est généralement placé en posi¬ tion supérieure pour couvrir le bassin lorsque la piscine n'est pas utilisée, et c'est uniquement lorsque la pis¬ cine est utilisée que ce fond mobile est commandé pour être abaissé de manière à permettre la baignade dans le bassin. Such a movable bottom is generally placed in posi tion ¬ upper to cover the pool when the pool is not used, and it is only when the udder ¬ cine is used this movable bottom is controlled to be lowered so as to allow swimming in the basin.
Un tel fond mobile comporte typiquement un struc¬ ture porteuse constituée d'un assemblage de profilés en métallique, recouvert d'un habillage constitué par exem¬ ple de lattes en bois espacées les unes des autres pour faciliter la circulation d'eau à travers le fond mobile lors de ses déplacements entre sa position supérieure et sa position inférieure. Such a mobile base typically comprises a struc ture ¬ carrier consists of an assembly of metal profiles covered with a dressing consisting of exam ple ¬ wood slats spaced apart from each other to facilitate the flow of water through the movable bottom when moving between its upper position and its lower position.
Les déplacements du corps de fond mobile sont as¬ surés par des moyens tels que des vérins, des vis sans fin, poulies, ou autres pilotés par une commande centra- lisée pour se déployer afin de remonter le fond mobile ou pour se rétracter afin de le redescendre. The displacements of the movable bottom body are as ¬ safe by means such as cylinders, worm gears, pulleys, or other controlled by a centralized control It is easy to deploy in order to go up the movable floor or to retract in order to lower it.
OBJET DE L'INVENTION  OBJECT OF THE INVENTION
Le but de l'invention est de proposer un agen- cernent de fond mobile ayant un coût de fabrication et d'installation réduits.  The object of the invention is to provide a mobile bottom frame having a reduced manufacturing and installation cost.
RESUME DE L'INVENTION  SUMMARY OF THE INVENTION
A cet effet, l'invention a pour objet un fond mobile destiné à équiper un bassin de piscine pour être placé soit dans une position inférieure dans laquelle il est au niveau du fond du bassin afin de permettre à des personnes de se baigner, soit dans une position supé¬ rieure dans laquelle il couvre ce bassin afin de consti¬ tuer une protection contre la noyade de personnes évo- luant aux abords de la piscine, caractérisé en ce qu'il comporte différents compartiments espacés les uns des au¬ tres, indépendants et constituant des cloches d'Archi- mède, ces compartiments permettant de faire flotter hori¬ zontalement ce fond mobile sur l'eau lorsqu'ils sont rem- plis d'air pour le placer en position supérieure, et de faire couler ce fond mobile lorsqu'ils sont remplis d'eau pour le placer en position inférieure, ainsi que des moyens commandés reliés à une source d'air pressurisé pour gérer la quantité d'air et d'eau indépendamment dans les différents compartiments de manière à incliner le fond mobile lors de ses déplacements entre la position supérieure et la position inférieure. For this purpose, the invention relates to a movable floor intended to equip a swimming pool to be placed either in a lower position in which it is at the bottom of the pool to allow people to bathe, either in a Supé ¬ higher position in which it covers the basin to consti ¬ kill protection against drowning persons EVO- diluent the edge of the pool, characterized in that it comprises various compartments spaced ¬ tres, independent and constituting of Archimedes Median bells, these compartments to float hori zontally ¬ this movable bottom on the water when replaced air folds to place it in the upper position, and to pour this movable bottom when they are filled with water to place it in the lower position, and controlled means connected to a source of pressurized air to manage the amount of air and water independently in the different compartments iments so as to incline the movable bottom when moving between the upper position and the lower position.
Avec cette solution, le déplacement du fond mobile entre ses deux positions extrêmes est assuré en pilotant uniquement une source d'alimentation d'air, ce qui est significativement moins coûteux et moins contraignant que la mise en œuvre et le pilotage de vérins pour réaliser ces déplacements. With this solution, the movement of the moving bottom between its two extreme positions is ensured by driving only a source of air supply, which is significantly less expensive and less restrictive than the implementation and control of cylinders to achieve these movements.

Comme visible dans la figure 1, le fond mobile se¬ lon l'invention qui est repéré par 1 est destiné à équi¬ per une piscine 2 en étant installé à l'intérieur du bas- sin 3 de cette piscine 2. Ce fond mobile 1 peut occuper une position inférieure comme dans la figure 1 dans la¬ quelle il repose sur le fond de ce bassin, et une posi¬ tion supérieure dans laquelle il est à hauteur de la sur¬ face 4 de l'eau 6 comme dans le cas des figures 3 à 5. As shown in Figure 1, the movable bottom is ¬ lon the invention which is denoted by 1 is intended to equi ¬ per pool 2 being installed inside the bas sin 3 of the swimming pool 2. This movable bottom 1 can occupy a lower position as in Figure 1 in the ¬ which it rests on the bottom of the basin, and a posi tion ¬ top in which it is level with the face 4 ¬ water 6 as in the case of Figures 3 to 5.
Ce fond mobile 1 comporte ici un compartiment cen¬ tral 7, et deux compartiments latéraux 8 et 9 situés de part et d'autre du compartiment central 7 pour être res¬ pectivement à proximité de deux bords opposés du bassin 3, ces compartiments étant destinés à recevoir de l'air et/ou de l'eau. This mobile base 1 comprises here a central compartment 7 tr ¬ and two lateral compartments 8 and 9 located on either side of the central compartment 7 to be res ¬ respectively near two opposite edges of the basin 3, these compartments being intended to receive air and / or water.
Il comporte en outre, au niveau d'un angle du bas¬ sin, un bras 11 qui s'étend sous un ensemble de trois marches 12, 13, 14 constituant un escalier 16 d'accès à au bassin, lorsque le corps du fond mobile 1 est en posi- tion inférieure comme dans la figure 1. Ces trois marches 12, 13 et 14, sont mobiles verti¬ calement indépendamment les unes des autres, en étant par exemple montées coulissantes chacune entre deux rails de guidage verticaux. Chaque marche comporte en outre un compartiment interne pouvant être rempli d'eau pour la placer en position basse comme dans la figure 1, ou bien rempli d'air pour la faire remonter par flottaison comme dans les figures 2 à 4. It further comprises, at an angle of the bottom ¬ sin, an arm 11 which extends under a set of three steps 12, 13, 14 constituting a staircase 16 access to the basin, when the bottom body mobile 1 is in the lower position as in FIG. These three steps 12, 13 and 14, are movable verti cally ¬ independently of each other, for example by being slidably mounted in each case between two vertical guide rails. Each step further comprises an internal compartment that can be filled with water to place it in the lower position as in Figure 1, or filled with air to make up by floating as in Figures 2 to 4.
Lorsque les trois marches 12, 13 et 14 sont en po- sition basse, elles constituent l'escalier 16 qui permet de descendre dans le bassin 3, et lorsqu'elles sont en position haute, les faces supérieures de ces trois mar¬ ches sont sensiblement à même hauteur, au dessus du ni¬ veau de la surface 4 de l'eau 6 du bassin 3. When the three steps 12, 13 and 14 are down, they are 16 stairs leading down into the basin 3, and when in raised position, the upper surfaces of these tasks are March 3 ¬ substantially at the same height, above the ni¬¬ surface 4 of the water 6 of the basin 3.
Comme indiqué ci-dessus, les compartiments 7, 8, 9 de la structure du fond mobile 1, et les compartiments de chaque marche 12, 13, 14 contiennent de l'eau et/ou de l'air, et des moyens commandés sont prévus pour gérer la quantité d'air contenue dans chaque compartiment.  As indicated above, the compartments 7, 8, 9 of the structure of the mobile bottom 1, and the compartments of each step 12, 13, 14 contain water and / or air, and controlled means are planned to manage the amount of air contained in each compartment.
Chaque compartiment constitue une cloche d'Archi- mède : il comporte d'une part une ouverture au niveau de sa région inférieure pour permettre continuellement l'en¬ trée et la sortie d'eau, et d'autre part un orifice au niveau de sa région supérieure pour permettre la sortie d'air, et il est en outre relié à une source commandée d'alimentation en air. Each compartment constitutes a bell Archimedes: it comprises on the one hand an opening at its lower region to continuously allow ¬ tree and the water outlet, and secondly a port at its upper region to allow the air outlet, and it is further connected to a controlled source of air supply.
Cette source d'alimentation fournit de l'air à une pression légèrement supérieure à la pression atmosphérique, une pression absolue de l'ordre de 1,2 bar étant normalement suffisante pour faire remonter le fond mobile du fond d'un bassin ayant une profondeur de deux mètres. L'air peut être issu d'un compresseur relié aux différents compartiments par un réseau de tubes disposés dans la structure du fond mobile. Cet air légèrement pressurisé peut être produit par effet venturi, en utili- sant un jet d'eau du système de régénération et de fil- tration de l'eau du bassin. This supply source supplies air at a pressure slightly greater than atmospheric pressure, an absolute pressure of the order of 1.2 bar being normally sufficient to raise the movable bottom of the bottom of a basin having a depth two meters. The air may be from a compressor connected to the different compartments by a network of tubes arranged in the structure of the mobile bottom. This slightly pressurized air can be produced by the venturi effect, using a jet of water from the regeneration and filtration system of the pond water.
La source d'alimentation en air peut être commandée pour injecter de l'air avec un débit supérieur au débit qu'autorise l'orifice supérieur, ce qui provoque dans un premier temps la sortie d'eau par l'ouverture inférieure, l'air se plaçant en partie supérieure du compartiment.  The air supply source can be controlled to inject air with a flow rate greater than the flow rate permitted by the upper orifice, which firstly causes the water outlet through the lower opening, the air placed in the upper part of the compartment.
Le maintien d'air dans le compartiment est alors assuré en maintenant en service la source d'alimentation en air, c'est-à-dire en continuant d'injecter de l'air pour renouveler l'air s ' évacuant par l'orifice supérieur, voire également par l'ouverture inférieure.  The maintenance of air in the compartment is then ensured by maintaining in service the air supply source, that is to say by continuing to inject air to renew the air evacuated by the upper orifice, or even through the lower opening.
Comme on le comprend, l'arrêt de l'alimentation en air permet l'évacuation de tout l'air contenu dans le compartiment par son orifice supérieur, attendu que l'eau vient naturellement prendre la place de l'air évacué.  As understood, the shutdown of the air supply allows the evacuation of all the air contained in the compartment through its upper orifice, since the water naturally takes the place of the exhaust air.
Une autre possibilité consiste à prévoir un clapet commandé ou une vanne commandée pour ouvrir ou fermer l'orifice supérieur. Dans ce cas le maintien d'air dans le compartiment nécessite simplement de maintenir le cla- pet fermé, et l'évacuation de l'air est obtenue en com¬ mandant ce clapet en ouverture. Another possibility is to provide a controlled valve or a controlled valve to open or close the upper orifice. In this case the air remaining in the compartment simply requires to keep the valve closed, and the evacuation of the air is obtained by com ¬ principal this valve opening.
Partant de la situation de la figure 1 dans la¬ quelle le fond mobile 1 est en position inférieure en ayant tous ses compartiments remplis d'eau, sa remontée jusqu'à une position supérieure est assurée en injectant de l'air de manière séquencée dans ses différents compar¬ timents . Starting from the situation of Figure 1 in the ¬ which the movable base 1 is in the lower position by having its water-filled compartments, its upward to an upper position is provided by injecting air so sequenced in its various compar ¬ buildings.
En premier lieu, de l'air est injecté d'une part dans l'un des deux compartiments latéraux, à savoir le compartiment 8 qui est le plus éloigné de l'escalier 16, et d'autre part dans les compartiments de chacune des trois marches 12, 13, 14. Le compartiment 8 constitue ainsi un flotteur de démarrage du mouvement qui permet d'alléger le fond mobile 1 du côté opposé aux marches 12, 13 et 14.  In the first place, air is injected into one of the two lateral compartments, namely the compartment 8 which is furthest from the staircase 16, and the compartments of each of the compartments. three steps 12, 13, 14. The compartment 8 thus constitutes a start float movement that lighten the movable bottom 1 on the side opposite the steps 12, 13 and 14.
A l'issue de cette première phase, le fond mobile 1 occupe une position inclinée correspondant à celle de la figure 2. Le bord de ce fond mobile 1 qui est opposé à celui de l'escalier 16, à savoir le bord le plus proche du compartiment 8 qui est rempli d'air, se trouve en po¬ sition supérieure au dessus de la surface 4 de l'eau 6. L'autre bord, à savoir le bord qui est le plus proche de l'escalier 16 est lui en position inférieure, de sorte que le bras 11 est situé au fond du bassin, à l'aplomb des trois marches 12, 13, 14 qui sont elles en position supérieure du fait que leurs compartiments sont remplis d'air. At the end of this first phase, the movable bottom 1 occupies an inclined position corresponding to that of FIG. 2. The edge of this movable bottom 1 which is opposite to that of the staircase 16, namely the nearest edge compartment 8 which is filled with air, is located in po sition ¬ higher above the surface 4 of the water 6. the other edge, namely the edge that is closest to the stairs 16 is him in the lower position, so that the arm 11 is located at the bottom of the pool, in line with the three steps 12, 13, 14 which are they in the upper position because their compartments are filled with air.
Une fois que la position inclinée de la figure 2 a été atteinte, le système est commandé pour injecter de l'air dans le deuxième compartiment latéral, à savoir le compartiment 9 qui est le plus proche du bord portant le bras 11.  Once the inclined position of FIG. 2 has been reached, the system is controlled to inject air into the second lateral compartment, namely the compartment 9 which is closest to the edge carrying the arm 11.
A l'issue du remplissage de ce deuxième comparti¬ ment latéral 9, le fond mobile 1 se place horizontalement dans une position supérieure dite intermédiaire, repré¬ sentée en figure 3. Dans cette position supérieure inter- médiaire, le fond mobile 1 est sensiblement au niveau de la surface 4 de l'eau 6, et son bras 11 s'étend sous les trois marches 12, 13 et 14 pour les bloquer en position haute . After the filling of the second compart ment side ¬ 9, the movable base 1 is placed horizontally in an upper position said intermediate, represented ¬ sented in Figure 3. In this upper position inter- mediate, the movable bottom 1 is substantially at the surface 4 of the water 6, and its arm 11 extends under the three steps 12, 13 and 14 to lock them in the high position.
Du fait qu'ils sont distincts, les compartiments peuvent être remplis d'air les uns après les autres afin de simplifier la gestion de la remontée du fond mobile en l'inclinant progressivement, ce qui permet notamment d'éviter qu'il ne se retourne de façon brutale.  Because they are distinct, the compartments can be filled with air one after the other to simplify the management of the rise of the movable bottom by tilting it gradually, which makes it possible in particular to prevent it from returns in a brutal way.
Une fois que le fond mobile a atteint la position supérieure intermédiaire de la figure 3, le système est commandé pour remplir d'air son compartiment central 7, de manière à faire remonter encore le fond mobile plus haut au dessus de la surface 4 de l'eau 6, afin qu'il at- teigne une position supérieure dite haute correspondant à celle de la figure 4.  Once the movable bottom has reached the intermediate upper position of FIG. 3, the system is controlled to fill its central compartment 7 with air, so as to raise the movable floor further up above the surface 4 of the water 6, so that it reaches a higher said high position corresponding to that of Figure 4.
Une fois que cette position supérieure haute a été atteinte, le système est commandé pour bloquer le fond mobile 1 en appui sur les bords supérieurs du bassin 3.  Once this upper upper position has been reached, the system is controlled to block the movable bottom 1 resting on the upper edges of the basin 3.
A cet effet, le fond mobile 1 est pourvu d'organes de blocage répartis le long de son pourtour, et qui se présentent par exemple sous la forme de barres 17 et 18, mobiles télescopiquement pour se déployer horizontalement afin de dépasser du contour du fond mobile 1, c'est-à- dire au delà du contour du bassin 3 vu de dessus.  For this purpose, the mobile bottom 1 is provided with locking members distributed along its periphery, and which are for example in the form of bars 17 and 18, telescopically movable to deploy horizontally to exceed the bottom contour mobile 1, that is to say beyond the outline of the basin 3 seen from above.
Comme illustré à la figure 4, lorsque les organes de blocage 17 et 18 encore appelés mains d'appui sont dé¬ ployés, ils s'étendent au dessus des bords latéraux 19 et 21 du bassin 3. As illustrated in FIG 4, when the locking members 17 and 18 also known as support ¬ hands are bent, they extend above the side edges 19 and 21 of basin 3.
Une fois que ces organes 17 et 18 ont été commandés pour se déployer, le système est piloté pour évacuer l'air contenu dans tous ses compartiments. Le fond mobile 1 redescend alors d'une certaine hauteur pour se placer en appui sur les bords 19 et 21 du bassin 3 grâce à ses moyens de blocage 17 et 18 déployés qui s'engagent alors dans des logements correspondants réalisés dans les bords 19 et 21. Once these organs 17 and 18 have been ordered to deploy, the system is piloted to evacuate the air contained in all its compartments. The moving bottom 1 then descends a certain height to be placed in abutment on the edges 19 and 21 of the basin 3 thanks to its locking means 17 and 18 deployed which then engage in corresponding housings made in the edges 19 and 21.
A ce stade qui correspond à la figure 5, le bassin est placé à sa position supérieure finale c'est-à-dire qu'il est à hauteur du sol entourant le bassin 3, et que son bras 11 maintient les marches mobiles 12, 13 et 14 bloquées à cette hauteur. Le fond mobile étant alors maintenu par ses organes de blocage, la présence d'eau dans le bassin n'est pas nécessaire à son maintien.  At this stage, which corresponds to FIG. 5, the basin is placed at its final upper position, that is to say that it is at the height of the ground surrounding the basin 3, and that its arm 11 holds the moving steps 12, 13 and 14 blocked at this height. The movable bottom is then maintained by its locking members, the presence of water in the basin is not necessary for its maintenance.
Le déplacement du fond mobile 1 depuis sa position supérieure finale de la figure 5, jusqu'à la position in¬ férieure de la figure 1 est assuré en commandant d'abord le système pour introduire de l'air dans les différents compartiments de manière à le faire remonter significati- vement au dessus de la surface 4 de l'eau 6. Moving the movable base 1 from its upper final position of Figure 5 to the position in ¬ férieure of Figure 1 is provided by first controlling the engine for introducing air into the various compartments so as to make it rise significantly above the surface 4 of the water 6.
Les organes de blocage 17 et 18 peuvent alors être commandés pour se rétracter. L'air peut alors être évacué du compartiment central 7, avant d'évacuer l'air du com¬ partiment latéral 9, ce qui a pour effet de provoquer la descente du fond mobile en position inclinée, comme dans le cas de la figure 2. The locking members 17 and 18 can then be controlled to retract. The air can then be evacuated from the central compartment 7, before evacuating the air com ¬ side part 9, which has the effect of causing the descent of the movable bottom in an inclined position, as in the case of Figure 2 .
A ce stade, l'air peut être évacué du compartiment 8, et des compartiments des marches 12, 13 et 14, ce qui permet de placer le fond mobile 1 à l'horizontale au fond du bassin 3, tout en configurant les marches mobiles 12, 13 et 14 en escalier 16, ce qui correspond à la situation de la figure 1. Partant de la situation de la figure 5, il est éga¬ lement possible de faire remonter le fond mobile 1 en po¬ sition supérieure haute pour rétracter ses organes de blocage, mais en vue de le faire redescendre uniquement de façon partielle, pour le placer à une position horizontale intermédiaire, pour réduire la profondeur du bas¬ sin 3, afin par exemple que des enfants puissent s'y bai¬ gner sans risque. At this stage, the air can be evacuated from the compartment 8, and the compartments of the steps 12, 13 and 14, which makes it possible to place the mobile bottom 1 horizontally at the bottom of the basin 3, while configuring the moving steps 12, 13 and 14 step 16, which corresponds to the situation of Figure 1. Starting from the position of Figure 5, it is EGA ¬ LEMENT possible to trace the mobile base 1 inch ¬ top high sition to retract its locking members, but to bring it down only partially, to place at an intermediate horizontal position, to reduce the depth of the bottom ¬ sin 3, for example that children can b㬠¬ ¬ safely.
Dans ce cas, le fond mobile 1 peut avantageusement être retenu à la hauteur intermédiaire au moyen de san¬ gles ayant chacune une extrémité fixée à un bord du bas¬ sin et une autre extrémité fixée au fond mobile, comme illustré schématiquement à la figure 6 dans laquelle ces sangles sont repérées par 22 et 23. In this case, the movable bottom 1 can advantageously be retained at the intermediate height by means of san ¬ gles each having an end attached to an edge of the bottom ¬ sin and another end fixed to the movable bottom, as shown schematically in Figure 6 in which these straps are marked by 22 and 23.
Complémentairement , ou bien alternativement, à ces sangles, le fond mobile peut être pourvu de pieds inter¬ médiaires réglables de faible hauteur, déployables, et permettant de stabiliser le fond à une hauteur intermé¬ diaire . Complementarily, or alternatively, these straps, the movable bottom may be provided with adjustable inter ¬ mediary legs of low height, deployable, and to stabilize the bottom at an intermediate height ¬ diaire.
Le fond mobile 1 selon l'invention est avantageuse¬ ment conçu pour supporter une personne adulte par mètre carré, tout en ayant une structure générale relativement légère . The mobile base 1 of the invention is advantageous ¬ ment designed to support an adult per square meter, while having a relatively light overall structure.
A cet effet, et comme illustré schématiquement en figure 7, le fond mobile selon l'invention comprend une structure générale constituée de poutres 24, assemblées avec des poutrelles 26 et éventuellement des lambourdes 27 pour constituer une base porteuse sur laquelle est rapporté un habillage non représenté.  For this purpose, and as illustrated schematically in FIG. 7, the movable bottom according to the invention comprises a general structure consisting of beams 24, assembled with beams 26 and possibly joists 27 to form a load-bearing base on which a non-cladding is attached. represent.
Cet habillage ou revêtement peut se présenter sous forme de lattes de bois, sous forme de carrelage ou au- tre, et il comporte avantageusement des interstices pour permettre une circulation d'eau importante à même de fa¬ ciliter les mouvements du fond mobile entre sa position supérieure et sa position inférieure. This covering or covering may be in the form of wooden slats, in the form of tiles or and it advantageously comprises interstices to allow a large flow of water able to fa ¬ cilitate the movements of the movable bottom between its upper position and its lower position.
Les poutres, poutrelles et lambourdes, ainsi que les éléments 28 constitutifs du bras 11 de blocage des marches de l'escalier sont avantageusement des profilés en fibre de verre pultrudée, qui présente de multiples avantages pour un tel fond mobile. En particulier, un tel matériau est incorrodable, solide, léger, insensible aux produits chlorées et à 1 ' électrolyse .  The beams, joists and joists, as well as the elements 28 constituting the arm 11 for locking the steps of the staircase are advantageously pultruded fiberglass profiles, which has multiple advantages for such a moving bottom. In particular, such a material is incorrodable, solid, light, insensitive to chlorinated products and electrolysis.
Les organes de blocage tels que l'organe 17 peuvent être commandés de manière centralisée, manuellement ou bien automatiquement, via une barre rotative 29 s'éten- dant perpendiculairement à ces organes, dans le plan du corps du fond mobile.  The locking members such as the member 17 can be controlled centrally, manually or automatically, via a rotating bar 29 extending perpendicularly to these members, in the plane of the body of the moving base.
Chaque barre coulissante d'un organe de blocage est alors rappelée vers une position déployée par un ressort de rappel non représenté, et elle a sont extrémité inté- rieure reliée à un câble 31 enroulé sur cette barre rota¬ tive 29. Une rotation de la barre provoque alors la ren¬ trée des organes de blocage, alors que le relâchement de cette barre en rotation provoque la sortie de ces orga¬ nes, sous l'effet de leurs ressorts de rappel. Each slide bar with a locking member is then biased toward an extended position by an unshown spring, and it is integral higher end connected to a cable 31 wound on this rota ¬ tive bar 29. Rotation of the then causes the bar ren ¬ tree locking members, while the release of the rotation bar causes the output of these orga ¬ nes, under the action of their return springs.
Afin de rendre le maintien du fond mobile plus sûr, par exemple pour de longues périodes hivernales, celui-ci peut encore être équipé de pieds inférieurs escamotable, tels que les pieds 32. Ces pieds 32 peuvent se présenter sous forme de vérins électriques ou pneumatiques, et peu- vent être déployés de manière commandée par l'utilisateur une fois que le fond mobile a atteint sa position supé¬ rieure finale. In order to make the maintenance of the moving base safer, for example for long winter periods, it can still be equipped with retractable lower legs, such as the feet 32. These feet 32 can be in the form of electric or pneumatic cylinders. , and can be deployed in a user-controlled manner once the mobile bottom has reached the position Supé ¬ final higher.
Le nombre de pieds peut être prévu pour que l'en¬ semble du fond mobile soit capable de supporter un ou des véhicules se garant sur le fond mobile en position haute. The number of feet can be provided so that en¬¬ appear mobile bottom is able to support one or vehicles parking on the movable floor in the high position.
Il est également possible de prévoir un agencement dans lequel les pieds escamotables 32 remplacent les mains de blocage 17 et 18 au lieu de les compléter. Dans ce cas, les pieds escamotables sont déployés lorsque le fond mobile est en position supérieure haute de la figure 5, avant de vider l'air des compartiments pour ramener le fond mobile à sa position supérieure finale.  It is also possible to provide an arrangement in which the retractable legs 32 replace the locking hands 17 and 18 instead of completing them. In this case, the retractable legs are deployed when the movable bottom is in the upper upper position of Figure 5, before emptying the compartment air to bring the movable bottom to its final upper position.
Le fond mobile selon l'invention peut avantageuse¬ ment être équipé de différents éléments complémentaires dépassant de son pourtour externe. Ces éléments peuvent se présenter sous forme d'un tuyau flexible 33 qui longe les poutrelles et poutres des bords du fond mobile. Ce tuyau flexible 33 est alors maintenu à faible distance des poutres qu'il porte, par exemple par des moyens élas- tiques tels que des ressorts, de manière à guider le fond mobile lors de sa remontée le long des faces internes du bassin, et de manière à amortir les éventuels chocs de ce fond mobile contre les parois du bassin. The movable base according to the invention can advantageously ¬ be equipped with various additional elements projecting from its outer periphery. These elements may be in the form of a flexible pipe 33 which runs along the beams and beams of the edges of the movable floor. This flexible pipe 33 is then kept at a small distance from the beams it carries, for example by elastic means such as springs, so as to guide the movable bottom when it rises along the internal faces of the basin, and so as to dampen the possible shocks of this movable bottom against the walls of the basin.
De manière analogue, une circulation d'eau peut être établie dans le fond mobile de manière à constituer des jets 34 éjectant de l'eau latéralement à l'horizon¬ tale, au delà du contour du fond mobile, de manière à guider et/ou amortir les éventuels chocs du fond mobile contre les parois du bassin. Similarly, a circulation of water can be established in the mobile bottom so as to form jets 34 ejecting water laterally to the horizon ¬ tale, beyond the contour of the moving bottom, so as to guide and / or dampen the possible shocks of the mobile bottom against the walls of the basin.
Ce pourtour peut encore être équipé de brosses 36 s 'étendant horizontalement de sorte que leurs poils dé- passent du contour, une telle brosse ayant là aussi pour effet de guider le fond mobile durant sa remontée, mais également d'éviter que des objets puissent tomber entre le fond mobile et le bord du bassin. This circumference may further be equipped with brushes 36 extending horizontally so that their hairs de They pass from the contour, such a brush also having the effect of guiding the moving bottom during its ascent, but also to prevent objects from falling between the movable bottom and the edge of the basin.
Chaque profilé utilisé pour constituer une poutre Each profile used to form a beam
24 ou une poutrelle 26 présente avantageusement une sec¬ tion transversale délimitant deux compartiments distinc¬ ts, comme illustré à la figure 8. Un tel profilé comporte en section transversale, une première portion 37 ouverte et destinée à constituer une gaine technique en recevant par exemple les tubes d'alimentation en air et autres ac- tionneurs ainsi que des câbles électriques, et une por¬ tion fermée 38 destinée à la constitution des comparti¬ ments devant recevoir l'air et/ou l'eau pour déplacer verticalement le fond mobile par flottaison. 24 or a beam 26 advantageously has a transverse sec¬ tion delimiting two compartments ¬ ts distinct, as shown in Figure 8. Such a section has in cross section, a first portion 37 open and intended to form a technical sheath receiving for example the air supply tubes and other actuators as well as electrical cables, and a closed por¬ tion 38 intended for the constitution of compartti ¬ to receive air and / or water to move vertically moving bottom by flotation.
Comme illustré schématiquement à la figure 8, la portion ouverte 37 de la section du profilé formant gaine technique, alors que la portion fermée est située en par¬ tie basse. La portion ouverte supérieure 37 est refermée soit par un couvercle spécifique, soit directement par l'habillage supérieur du fond mobile selon l'invention. Par ailleurs, ces poutres et poutrelles sont obstruées à leurs extrémités pour constituer facilement des comparti¬ ments à même de recevoir de l'air et de l'eau. As illustrated schematically in Figure 8, the open portion 37 of the section of the profile forming technical sheath, whereas the closed portion is located in ¬ low tie. The upper open portion 37 is closed either by a specific cover, or directly by the upper covering of the movable bottom of the invention. Furthermore, these beams and beams are obstructed at their ends to easily form compartti ¬ able to receive air and water.
La section de profilé représentée en figure 8 qui correspond aux poutres et poutrelles constituant la structure du corps de fond mobile, peut aussi être utili¬ sée pour constituer des rails latéraux de montage des marches mobiles, permettant de monter ces marches coulis- santés verticalement en guidant leurs mouvements. Concrètement, ces mêmes profilés peuvent être fixés verticalement aux parois du bassin de la piscine dans la région de son escalier d'accès, par paires se faisant face pour constituer chacun un système de guidage des deux extrémités d'une marche coulissant verticalement. The profile section shown in Figure 8 which correspond to the beams and girders constituting the structure of the movable bottom body, can also be utili ¬ Sée to constitute side rail assembly movable steps, for mounting these steps coulis- toasts vertically guiding their movements. Concretely, these same profiles can be fixed vertically to the walls of the pool in the region of its access staircase, in pairs facing each other to constitute each a guide system of the two ends of a sliding step vertically.
Un tel agencement est représenté en figure 9, dans laquelle on a prévu trois paires de rails verticaux, re¬ pérés respectivement par 12a et 12b, 13a et 13b, ainsi que 14a et 14b, ces paires de rails étant destinées à re- cevoir respectivement les marches 12, 13, et 14 non re¬ présentées dans la figure 9. Such an arrangement is represented in FIG. 9, in which three pairs of vertical rails, re ¬ respectively, have been provided by 12a and 12b, 13a and 13b, and 14a and 14b, these pairs of rails being intended to respectively receive the steps 12, 13, and 14 not re ¬ shown in Figure 9.
Comme illustré à la figure 9 les deux rails de cha¬ que paire sont positionnés de telle manière que leurs portions ouvertes se font face, de façon à délimiter cha- cune une section de guidage dans laquelle peut être enga¬ gée une extrémité de marche ayant une forme complémen¬ taire. Les portions fermées de chacun de ces rails of¬ frent à ceux-ci une rigidité mécanique suffisante pour qu'ils puissent offrir une rectitude de guidage appro- priée en toute circonstance. As illustrated in Figure 9 the two rails cha ¬ pair are positioned such that their open portions face each other, so as to delimit Cha- CUNE a guide section in which can be enga ¬ Gée a walking end having a comple form ¬ silent. The closed portions of each of these rails of ¬ frent them to a sufficient mechanical rigidity so that they can offer an appropriate guiding straightness in all circumstances.
D'une manière générale, le fond mobile selon l'in¬ vention peut rester sans risque et sans eau, aussi bien en position inférieure qu'en position supérieure et intermédiaire. Il est avantageusement équipé d'une trappe d'accès réalisée dans le revêtement, entre deux poutres ou poutrelles de manière à permettre l'introduction d'un robot de nettoyage dans le bassin lorsque ce fond mobile est en position supérieure. In general, the mobile base according to the in vention ¬ can remain safely and without water, both in the lower position than the upper and intermediate position. It is advantageously equipped with an access hatch made in the coating, between two beams or beams so as to allow the introduction of a cleaning robot in the basin when the movable bottom is in the upper position.
Comme on le comprend, le fond mobile selon 1 ' inven- tion peut être installé dans un bassin indépendamment du revêtement de ce bassin qui peut être une membrane de type liner, du béton brut, du carrelage ou autre. As can be understood, the mobile bottom according to the invention can be installed in a pool independently of the coating of this basin which may be a liner type membrane, raw concrete, tile or other.
Le fond mobile selon l'invention peut également comporter une banquette ou encore un escalier prévus fixes ou mobiles par rapport au corps de fond mobile.  The movable bottom of the invention may also include a bench or a staircase provided fixed or movable relative to the movable bottom body.
