DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

L'idée à la base de l'invention est un fond mobile pourvu de compartiments pouvant être sélectivement remplis d'air pour le faire remonter par flottaison, ou bien remplis d'eau pour le faire descendre au fond du bassin.The idea underlying the invention is a movable floor provided with compartments that can be selectively filled with air to make up by flotation, or filled with water to make it down to the bottom of the pool.

Comme visible dans la figure 1, le fond mobile selon l'invention qui est repéré par 1 est destiné à équiper une piscine 2 en étant installé à l'intérieur du bassin 3 de cette piscine 2. Ce fond mobile 1 peut occuper une position inférieure comme dans la figure 1 dans laquelle il repose sur le fond de ce bassin, et une position supérieure dans laquelle il est à hauteur de la surface 4 de l'eau 6 comme dans le cas des figures 3 à 5.As visible in the figure 1 , the movable bottom according to the invention which is marked by 1 is intended to equip a pool 2 being installed inside the pool 3 of the pool 2. This movable bottom 1 can occupy a lower position as in the figure 1 in which it rests on the bottom of this basin, and an upper position in which it is at the height of the surface 4 of the water 6 as in the case of Figures 3 to 5 .

Ce fond mobile 1 comporte ici un compartiment central 7, et deux compartiments latéraux 8 et 9 situés de part et d'autre du compartiment central 7 pour être respectivement à proximité de deux bords opposés du bassin 3, ces compartiments étant destinés à recevoir de l'air et/ou de l'eau.This movable base 1 here comprises a central compartment 7, and two lateral compartments 8 and 9 located on either side of the central compartment 7 to be respectively close to 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 bassin, 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 position inférieure comme dans la figure 1.It further comprises, at an angle of the pelvis, an arm 11 which extends under a set of three steps 12, 13, 14 constituting a staircase 16 of access to the basin, when the body of the moving bottom 1 is in the lower position as in the figure 1 .

Ces trois marches 12, 13 et 14, sont mobiles verticalement 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.These three steps 12, 13 and 14 are movable vertically independently of each other, for example being slidably mounted each 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 the figure 1 , or filled with air to float it up as in the Figures 2 to 4 .

Lorsque les trois marches 12, 13 et 14 sont en position 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 marches sont sensiblement à même hauteur, au dessus du niveau de la surface 4 de l'eau 6 du bassin 3.When the three steps 12, 13 and 14 are in the lower position, they constitute the staircase 16 which allows to descend into the basin 3, and when they are in the upper position, the upper faces of these three steps are substantially at the same height. , above the level of the 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'Archimède : il comporte d'une part une ouverture au niveau de sa région inférieure pour permettre continuellement l'entrée 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 an Archimedean bell: it comprises on the one hand an opening at its lower region to continuously allow the entry and exit of water, and on the other hand an orifice at its upper region for 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.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.

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 utilisant un jet d'eau du système de régénération et de filtration de l'eau du bassin.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 venturi effect, using a water jet of the regeneration and filtration system of the water of the basin.

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 clapet fermé, et l'évacuation de l'air est obtenue en commandant 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 maintenance of air in the compartment simply requires keeping the valve closed, and the air evacuation is obtained by controlling the valve opening.

Partant de la situation de la figure 1 dans laquelle 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 compartiments.Starting from the situation of figure 1 in which the movable bottom 1 is in the lower position having all its compartments filled with water, its rise to an upper position is ensured by injecting air sequentially in its different compartments.

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 position 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 mobile bottom 1 occupies an inclined position corresponding to that of the figure 2 . The edge of this movable bottom 1 which is opposite to that of the staircase 16, namely the edge closest to the compartment 8 which is filled with air, is in the upper position above the surface 4 of the water 6. The other edge, namely the edge that is closest to the staircase 16 is it 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 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 the figure 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 compartiment latéral 9, le fond mobile 1 se place horizontalement dans une position supérieure dite intermédiaire, représentée en figure 3. Dans cette position supérieure intermédiaire, 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 this second lateral compartment 9, the mobile bottom 1 is placed horizontally in a so-called intermediate upper position, represented in FIG. figure 3 . In this intermediate upper position, 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 atteigne une position supérieure dite haute correspondant à celle de la figure 4.Once the moving bottom has reached the intermediate upper position of the figure 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 so-called upper upper 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 déployés, ils s'étendent au dessus des bords latéraux 19 et 21 du bassin 3.As illustrated in figure 4 when the locking members 17 and 18 still called support hands are deployed, they extend above the lateral edges 19 and 21 of the 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 the figure 5 , the basin is placed at its final upper position that is to say it is at the height of the ground surrounding the basin 3, and his arm 11 maintains the movable 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 inférieure 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 significativement au dessus de la surface 4 de l'eau 6.The displacement of the moving bottom 1 from its final upper position of the figure 5 , to the lower position of the figure 1 is ensured by first ordering the system to introduce air into the different compartments so as to raise 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 compartiment 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 from the lateral compartment 9, which has the effect of causing the lowering of the movable bottom in an inclined position, as in the case of the 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.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 the figure 1 .

Partant de la situation de la figure 5, il est également possible de faire remonter le fond mobile 1 en position 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 bassin 3, afin par exemple que des enfants puissent s'y baigner sans risque.Starting from the situation of figure 5 it is also possible to raise the movable bottom 1 to upper upper position to retract its locking members, but to make it down only partially, to place it in an intermediate horizontal position, to reduce the depth of the basin 3, for example that children can swim safely.

Dans ce cas, le fond mobile 1 peut avantageusement être retenu à la hauteur intermédiaire au moyen de sangles ayant chacune une extrémité fixée à un bord du bassin 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 straps each having an end fixed to one edge of the basin and another end fixed to the moving bottom, as shown schematically in FIG. 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 intermédiaires réglables de faible hauteur, déployables, et permettant de stabiliser le fond à une hauteur intermédiaire.Complementarily, or alternatively, these straps, the movable bottom may be provided with adjustable intermediate legs of low height, deployable, and to stabilize the bottom at an intermediate height.

Le fond mobile 1 selon l'invention est avantageusement conçu pour supporter une personne adulte par mètre carré, tout en ayant une structure générale relativement légère.The movable bottom 1 according to the invention is advantageously designed to support an adult person 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 figure 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 bearing base on which is reported dressing not shown.

Cet habillage ou revêtement peut se présenter sous forme de lattes de bois, sous forme de carrelage ou autre, et il comporte avantageusement des interstices pour permettre une circulation d'eau importante à même de faciliter les mouvements du fond mobile entre sa position supérieure et sa position inférieure.This covering or coating can be in the form of wooden slats, in the form of tiles or other, and it advantageously comprises interstices to allow a large flow of water capable of facilitating 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 l'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'étendant 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 bodies, in the plane of the body of the movable bottom.

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 intérieure reliée à un câble 31 enroulé sur cette barre rotative 29. Une rotation de la barre provoque alors la rentrée des organes de blocage, alors que le relâchement de cette barre en rotation provoque la sortie de ces organes, sous l'effet de leurs ressorts de rappel.Each sliding bar of a locking member is then returned to a deployed position by a return spring not shown, and it has its inner end connected to a cable 31 wound on this rotating bar 29. A rotation of the bar then causes the retraction of the locking members, while the release of this rotating bar causes the output of these bodies, under the effect 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 peuvent être déployés de manière commandée par l'utilisateur une fois que le fond mobile a atteint sa position supérieure finale.In order to make the maintenance of the moving bottom 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 moving bottom has reached its final upper position.

Le nombre de pieds peut être prévu pour que l'ensemble 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 the entire movable bottom is capable of supporting one or more 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 the figure 5 , before emptying the air compartments to bring the movable bottom to its final upper position.

Le fond mobile peut avantageusement 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 élastiques 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 bottom may advantageously be equipped with different complementary elements protruding 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 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'horizontale, 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 horizontally, beyond the contour of the moving bottom, so as to guide and / or dampen 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 dépassent 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 can still be equipped with brushes 36 extending horizontally so that their hairs exceed contour, such a brush also having the effect of guiding the movable 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 24 ou une poutrelle 26 présente avantageusement une section transversale délimitant deux compartiments distincts, 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 actionneurs ainsi que des câbles électriques, et une portion fermée 38 destinée à la constitution des compartiments devant recevoir l'air et/ou l'eau pour déplacer verticalement le fond mobile par flottaison.Each profile used to form a beam 24 or a beam 26 advantageously has a cross section delimiting two distinct compartments, as illustrated in FIG. figure 8 . Such a section comprises in cross section, a first portion 37 open and intended to form a technical sheath by receiving for example the air supply tubes and other actuators and electrical cables, and a closed portion 38 for the constitution of compartments for receiving air and / or water to vertically move the movable 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 partie 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 compartiments 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 duct, while the closed portion is located at the bottom. 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. In addition, these beams and beams are clogged at their ends to easily form compartments 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 utilisée pour constituer des rails latéraux de montage des marches mobiles, permettant de monter ces marches coulissantes verticalement en guidant leurs mouvements.The profile section shown in figure 8 which corresponds to the beams and beams constituting the structure of the moving bottom body, can also be used to form side rails mounting movable steps, to mount these sliding steps vertically guiding their movements.

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.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, repérés respectivement par 12a et 12b, 13a et 13b, ainsi que 14a et 14b, ces paires de rails étant destinées à recevoir respectivement les marches 12, 13, et 14 non représentées dans la figure 9.Such an arrangement is represented in figure 9 , in which there are three pairs of vertical rails, marked respectively by 12a and 12b, 13a and 13b, and 14a and 14b, these pairs of rails being intended to receive respectively the steps 12, 13, and 14 not shown in the figure 9 .

Comme illustré à la figure 9 les deux rails de chaque paire sont positionnés de telle manière que leurs portions ouvertes se font face, de façon à délimiter chacune une section de guidage dans laquelle peut être engagée une extrémité de marche ayant une forme complémentaire. Les portions fermées de chacun de ces rails offrent à ceux-ci une rigidité mécanique suffisante pour qu'ils puissent offrir une rectitude de guidage appropriée en toute circonstance.As illustrated in figure 9 the two rails of each pair are positioned in such a way that their open portions face each other, so as to delimit each a guide section in which can be engaged a walking end having a complementary shape. The closed portions of each of these rails provide them with sufficient mechanical rigidity so that they can provide proper guiding straightness under any circumstance.

D'une manière générale, le fond mobile selon l'invention 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 bottom according to the invention can remain safely and without water, both in the lower position and in 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 l'invention 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 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 peut également comporter une banquette ou encore un escalier prévus fixes ou mobiles par rapport au corps de fond mobile.The movable floor may also include a bench or a staircase provided fixed or movable relative to the movable bottom body.
