Description

La législation relative à la sécurité à l'intérieur et dans l'environnement des piscines a fortement évolué au cours des dernières années, suscitant dans ce secteur professionnel l'avènement de nombreux accessoires, procédés ou dispositifs en charge de sécuriser l'approche des bassins ou encore alerter lors de la chute d'un corps dans l'eau.The legislation relating to indoor and outdoor swimming pool safety has evolved considerably in recent years, sparking in this professional sector the advent of numerous accessories, processes or devices in charge of securing the pool approach. or alert when a body falls into the water.

C'est ainsi qu'il est commun de rencontrer sur ce secteur de marché, divers modèles de barrières, murs ou rambardes conçues spécialement pour interdire aux enfants sans surveillance d'accéder seuls au bassin de la piscine. Ce moyen physique interdisant l'accès, n'assure pas toujours une totale sécurité, car la plupart du temps, il ne peut s'opposer efficacement à l'escalade et au franchissement.Thus, it is common to meet in this market sector, various models of barriers, walls or railings designed specifically to prohibit unattended children to access the pool alone. This physical means prohibiting access, does not always ensure total security, because most of the time, it can not effectively oppose escalation and crossing.

De nombreux autres dispositifs sont aujourd'hui disponibles dans le commerce, comme par exemple les alarmes sonores conçues pour signaler dans l'environnement proche du bassin, la chute d'un corps ou d'un objet dans l'eau. Ces dispositifs interviennent souvent, malheureusement, lorsque le mal est fait, c'est-à-dire lorsque l'enfant est tombé dans l'eau et qu'il est déjà en situation de détresse. La sauvegarde de l'intéressé dépend alors en premier lieu de la perception de l'alarme sonore par quelqu'un de son entourage, ce qui peut parfois être aléatoire lorsque d'autres bruits occupent l'environnement et en second lieu de la vitesse d'intervention, des personnes ayant perçu le signal d'alarme, qui peuvent être à ce moment précis très éloignées du bassin.Many other devices are now commercially available, such as sound alarms designed to signal in the vicinity of the basin, the fall of a body or an object in the water. These devices often occur, unfortunately, when the harm is done, that is to say when the child has fallen into the water and is already in distress. The safeguarding of the person concerned then depends primarily on the perception of the sound alarm by someone around him, which can sometimes be random when other noises occupy the environment and secondly the speed of intervention, people who have perceived the alarm signal, who may be at this very moment very far from the basin.

Certains professionnels proposent alors divers dispositifs permettant de recouvrir totalement la surface de l'eau en dehors des heures de baignade, en déroulant ou en faisant coulisser un écran protecteur carrément en contact avec l'eau ou très légèrement au-dessus de celle-ci. On se référera par exemple aux documents US-A-5 542 502 , DE10 2006 003504 A1 et US 2001/047540 décrivant de tels dispositifs.Some professionals then offer various devices to completely cover the surface of the water outside the bathing hours, by unwinding or sliding a protective screen squarely in contact with water or very slightly above it. For example, documents US-A-5,542,502 , DE10 2006 003504 A1 and US 2001/047540 describing such devices.

Si ce genre de procédé semble très efficace pour éviter la chute dans l'eau de feuilles et autres déchets végétaux légers, la rigidité de l'écran déroulé ou déplié est souvent insuffisante pour retenir suffisamment longtemps le corps d'un enfant tombé accidentellement dans le bassin.If this kind of process seems very effective to prevent the drop in water of leaves and other light vegetable waste, the rigidity of the screen unrolled or unfolded is often insufficient to hold the body of a child accidentally fallen into the pelvis long enough.

A ce jour, il semble que le plus efficace des systèmes de sécurité pour piscine soit la présence d'un fond rigide mobile qui, totalement immergé au plus profond du bassin au moment de la baignade, est relevé en fin de baignade pour venir couvrir toute la surface de la piscine, offrant ainsi une sécurité totale par une rigidité et une résistance à la chute particulièrement adaptées.To date, it seems that the most effective swimming pool safety system is the presence of a mobile hard bottom which, fully submerged deep in the pool at the time of swimming, is raised at the end of swimming to cover all the surface of the pool, thus offering total safety by rigidity and resistance to the fall particularly adapted.

Néanmoins, ce genre de dispositif de fond mobile présente selon les systèmes certains inconvénients techniques comme par exemple, l'occupation en fond de bassin d'un volume important entre le fond mobile et le fond du bassin, pour la localisation et la mise en oeuvre de mécanismes immergés. Dans un tel cas, la profondeur utile du bassin de la piscine est sensiblement réduit.Nevertheless, this type of mobile bottom device has, according to the systems, certain technical drawbacks, for example the fact that the bottom of the pond is occupied with a large volume between the mobile bottom and the bottom of the basin, for the localization and the implementation. submerged mechanisms. In such a case, the useful depth of the pool is substantially reduced.

D'autre part, de nombreux bassins de piscines présentent un fond incliné pour offrir aux baigneurs, un bassin peu profond à une extrémité (petit bassin) et un bassin plus profond à l'autre extrémité (grand bassin).On the other hand, many pool pools have an inclined bottom to offer bathers, a shallow pool at one end (small pool) and a deeper pool at the other end (large pool).

La rigidité du fond mobile est dans ce procédé un facteur de sécurité majeur. En effet, selon l'endroit de la chute du corps sur le fond mobile, celui-ci peut se déformer localement et suffisamment pour permettre au corps de passer sous le fond mobile, provoquant ainsi et quasi inévitablement la noyade.In this process, the rigidity of the moving floor is a major safety factor. Indeed, depending on the location of the fall of the body on the mobile bottom, it can deform locally and sufficiently to allow the body to pass under the mobile bottom, causing and almost inevitably drowning.

Plusieurs techniques ont été mises en oeuvre par les professionnels pour concilier la rigidité du fond mobile avec sa mobilité dans l'eau lors de la plongée ou du levage.Several techniques have been implemented by professionals to reconcile the rigidity of the mobile bottom with its mobility in the water during diving or lifting.

Le plus souvent, les fonds mobiles rencontrés dans le commerce ou l'état de la technique présentent des orifices facilitant le passage de l'eau au travers du fond mobile. Cet aménagement diminue sensiblement la résistance au déplacement et facilite la mobilité.Most often, mobile funds encountered in commerce or the state of the art have holes facilitating the passage of water through the movable floor. This arrangement substantially reduces the resistance to movement and facilitates mobility.

D'autre part, les règlements en vigueur définissent avec précision les dimensions d'un espace périphérique entre le bord du fond mobile et les parois du bassin. Cet espace a pour objet principal de faciliter les mouvements d'eau lors des déplacements du fond mobile dans le bassin tout en interdisant les accidents qui pourraient être provoqués par l'engagement du pied d'un baigneur dans cet espace.On the other hand, the regulations in force define precisely the dimensions of a peripheral space between the edge of the movable bottom and the walls of the basin. This space has the main purpose of facilitating the movement of water during movement of the movable floor in the basin while prohibiting accidents that could be caused by the engagement of the foot of a bather in this space.

Il apparaît donc que la sécurité maximum passe par la multiplication des points d'ancrage et de levage du fond mobile qui garantit une rigidité optimum et une bonne résistance à la chute d'un corps. Ce constat est d'autant plus vérifiable que la surface de la piscine est grande ou ses formes hors du commun.It therefore appears that the maximum safety passes through the multiplication of anchoring points and lifting of the movable bottom which guarantees optimum rigidity and good resistance to the fall of a body. This observation is even more verifiable that the surface of the pool is large or its forms out of the ordinary.

Pourtant l'état de la technique laisse apparaître le plus souvent des points de levage en nombre limité, comme par exemple quatre points de levage répartis aux quatre coins de la piscine lorsque celle-ci est de forme carrée ou rectangulaire.However, the state of the art reveals most often lifting points in limited numbers, such as four lifting points distributed at the four corners of the pool when it is square or rectangular.

La limitation du nombre de points de levage est le plus souvent due à la complexité des dispositifs mis en place pour agir simultanément sur les dits points de levage. Cette complexité des cinématiques mises en oeuvre est d'autant plus grande que le nombre de points de levage du fond mobile est élevé.The limitation of the number of lifting points is most often due to the complexity of the devices set up to act simultaneously on said lifting points. This complexity of the kinematics implemented is even greater than the number of lifting points of the moving floor is high.

Par exemple, on peut relever dans l'état de la technique des dispositifs agissant au moyen de vérins pneumatiques ou hydrauliques coopérant avec un jeu de câbles et poulies déployé tout autour de la piscine. Ce genre de dispositif à lourde cinématique implique des aménagements importants et coûteux, à l'intérieur, à l'extérieur et à proximité du bassin ce qui conduit inévitablement à de mauvais fonctionnements, pannes, interventions sur zones enterrées et consécutivement à l'élévation des coûts d'installation et de maintenance.For example, it can be noted in the state of the art devices acting by means of pneumatic or hydraulic cylinders cooperating with a set of cables and pulleys deployed around the pool. This type of heavy kinematic device involves significant and costly adjustments, inside, outside and near the basin which inevitably leads to malfunctions, breakdowns, interventions on buried zones and following the rise of installation and maintenance costs.

Des dispositifs similaires associent également l'intégration de vérins et réseaux de câbles et poulies dans la structure même du fond mobile, ce qui rajoute aux inconvénients précédemment cités celui de l'immersion de composants mécaniques actifs en milieu aquatique chloré.Similar devices also combine the integration of jacks and cable networks and pulleys in the structure of the mobile bottom, which adds to the drawbacks mentioned above that of the immersion of mechanical components active in a chlorinated aquatic environment.

Tous les dispositifs aujourd'hui présents dans l'état de la technique impliquent l'immersion de câbles métalliques dans l'eau, lesdits câbles étant actionnés au moyen de poulies traditionnelles enterrées à l'extérieur du bassin ou elles-mêmes immergées dans l'eau du bassin.All devices present today in the state of the art involve the immersion of metal cables in the water, said cables being actuated by means of traditional pulleys buried outside the basin or themselves immersed in the pond water.

La présente invention a pour but d'apporter une amélioration sensible des éléments de manoeuvre d'un fond mobile à l'intérieur d'un bassin et ainsi réduire considérablement l'implication d'accessoires, aménagements et travaux dans la construction d'une piscine et par voie de conséquence en diminuer le coût.The present invention aims to provide a significant improvement in the operating elements of a movable floor inside a pool and thus significantly reduce the involvement of accessories, amenities and work in the construction of a pool and consequently reduce the cost.

A cet effet, l'invention a pour objet un module de levage pour fond rigide mobile de piscine, caractérisé en ce qu'il comprend :

  1. a) un boîtier d'entraînement commandant les mouvements d'immersion et de levage en un point unique du fond mobile,
  2. b) au moins un élément de guidage périphérique du fond mobile,
  3. c) au moins un élément de transmission relié d'une part au boîtier d'entraînement, et d'autre part audit point unique du fond mobile,
le module de levage étant totalement autonome en ce sens qu'il est dépourvu de liaison mécanique avec un quelconque autre moyen de levage agissant en un autre point de levage du fond mobile.For this purpose, the subject of the invention is a lifting module for a rigid swimming pool bottom, characterized in that it comprises:
  1. a) a drive box controlling the immersion and lifting movements at a single point of the moving bottom,
  2. b) at least one peripheral guide element of the movable floor,
  3. c) at least one transmission element connected on the one hand to the drive housing, and on the other hand to said single point of the moving base,
the lifting module being completely autonomous in that it has no mechanical connection with any other lifting means acting at another lifting point of the movable floor.

Ainsi le module autonome de levage selon l'invention est d'une grande simplicité structurelle, contrairement à de nombreux dispositifs de l'état de la technique qui présentent une seule unité centrale d'entraînement agissant sur plusieurs points de levage par l'intermédiaire d'installations complexes et de mécanismes encombrants (nombreux câbles, poulies, vérins, leviers etc.), technique qui implique de lourds travaux et aménagements dans le bassin et hors du bassin et en conséquence des coûts et temps d'installation élevés. Le module autonome de levage selon l'invention est disposé en autant d'unités que nécessaire tout autour et à l'extérieur d'un bassin de piscine, pour permettre l'immersion totale et le levage d'un fond mobile. Les différents modules de levage installés autour du bassin sont rigoureusement identiques. Ils peuvent être pilotés indépendamment les uns des autres. Il suffit par des réglages simples après installation de synchroniser les différents modules autonomes de levage pour parvenir à la coopération recherchée.Thus the autonomous lifting module according to the invention is of great structural simplicity, unlike many devices of the state of the art which have a single central drive unit acting on several lifting points via complex installations and bulky mechanisms (many cables, pulleys, cylinders, levers etc.), which involves heavy work and development in the basin and out of the basin and as a result of the high costs and installation time. The autonomous lifting module according to the invention is arranged in as many units as necessary all around and outside a swimming pool, to allow total immersion and lifting of a movable floor. The different lifting modules installed around the pool are exactly the same. They can be controlled independently of each other. By simple adjustments after installation, it is sufficient to synchronize the different autonomous lifting modules to achieve the desired cooperation.

On a représenté à la figure 1 les principaux éléments constituant un module de levage 100 suivant l'invention. Ce dernier comprend un boîtier d'entraînement A commandant les mouvements d'immersion (au sens de descente) et de levage du fond mobile 3. Le module de levage 100 comprend également un élément de guidage B d'une zone périphérique du fond mobile 3. Le module de levage 100 comprend encore un élément de transmission C relié d'une part au boîtier d'entraînement A, et d'autre part au fond mobile 3.We have shown figure 1 the main elements constituting a lifting module 100 according to the invention. The latter comprises a drive unit A controlling the immersion movements (in the direction of descent) and lifting of the moving base 3. The lifting module 100 also comprises a guide element B of a peripheral zone of the moving base 3 The lifting module 100 further comprises a transmission element C connected on the one hand to the drive housing A and on the other hand to the moving bottom 3.

Selon l'invention, le module de levage 100 agit en un point unique de levage. La notion de « point de levage » s'entend comme une zone restreinte à la périphérie du fond mobile 3, de l'ordre de quelques centimètres ou décimètres. Selon un aspect essentiel de l'invention, l'élément de transmission C est donc relié au fond mobile 3 en un point unique de levage. On imprime un mouvement d'immersion (ou de descente) ou de levage au fond mobile 3, par un ensemble de modules de levage 100 qui sont disposés en autant d'unités que nécessaire, sur des bords du bassin D de la piscine. La figure 2 illustre l'implantation de six modules de levage 100 agissant en six point de levage du fond mobile 3. Le nombre et la répartition des modules de levage sont fonction de la charge à supporter et à entraîner, qui dépend directement du poids du fond mobile 3, mais également de la forme du fond mobile 3. Il importe de viser une répartition équilibrée et le plus homogène possible des efforts à supporter par chacun des modules de levage 100.According to the invention, the lifting module 100 acts at a single point of lifting. The concept of "lifting point" means a zone restricted to the periphery of the movable floor 3, of the order of a few centimeters or decimetres. According to an essential aspect of the invention, the transmission element C is therefore connected to the moving bottom 3 at a single lifting point. An immersion (or descent) or lifting movement is imparted to the moving bottom 3 by a set of lifting modules 100 which are arranged in as many units as necessary on the edges of the Pool D of the pool. The figure 2 illustrates the implantation of six lifting modules 100 acting at six lifting point of the movable base 3. The number and distribution of the lifting modules are a function of the load to be supported and driven, which depends directly on the weight of the moving floor 3 but also the shape of the movable bottom 3. It is important to aim for a balanced distribution and the most homogeneous possible efforts to support each of the lifting modules 100.

Selon l'invention, les modules de levage 100 de l'installation sont activés par un dispositif de réglage et de synchronisation. Ce dernier est adapté à piloter des courses de levage qui peuvent être semblables ou différentes en chaque point de levage. Ainsi, les différents modules 100 peuvent commander le déplacement du fond mobile 3 en le conservant sensiblement horizontal quel que soit sa hauteur. Les différents modules 100 peuvent commander le déplacement du fond mobile 3 en l'inclinant selon un angle souhaité, par exemple de manière à épouser un fond de la piscine qui serait lui-même incliné par rapport à un plan horizontal.According to the invention, the lifting modules 100 of the installation are activated by an adjustment and synchronization device. The latter is adapted to control lifting strokes that may be similar or different at each lifting point. Thus, the various modules 100 can control the displacement of the mobile base 3 while keeping it substantially horizontal regardless of its height. The various modules 100 can control the displacement of the mobile base 3 by tilting it to a desired angle, for example so as to fit a bottom of the pool which would itself be inclined with respect to a horizontal plane.

Le boîtier d'entraînement A comprend un moteur M, M' relié à l'élément de transmission C. Cette liaison est assurée par des moyens d'entraînement (non représentés) tels qu'un jeu de poulies ou accessoires ou des moyens de réduction, qui sont classiques et d'une conception parfaitement à la portée de l'homme du métier.The drive housing A comprises a motor M, M 'connected to the transmission element C. This connection is provided by drive means (not shown) such as a set of pulleys or accessories or reduction means which are classic and of a design perfectly within the reach of the skilled person.

Dans un premier mode de réalisation de l'invention, le moteur M est un moteur animé par énergie électrique. Le moteur est raccordé à un circuit électrique standard et conforme aux règles en vigueur en matière d'alimentation électrique d'équipements extérieurs. A titre d'exemple, pour un fond mobile de 1500 kg, une vitesse de remontée de 0,03 m/s, un rayon de poulie de 0,05 m en sortie d'arbre moteur, une accélération linéaire de 1m/s2, un rendement de 0,6 et une distance au levage de 2,5 m, on obtient une puissance mécanique nécessaire de l'ordre de 75 W pour un couple nominal de 125 Nm. En se basant sur une hypothèse de quatre modules, donc quatre moteurs électriques, on divise par quatre la puissance nécessaire pour chacun. En admettant un coefficient de sécurité de l'ordre de 1,5, nous obtenons une puissance mécanique unitaire de l'ordre de 37,50 W pour un couple unitaire de 41,67 Nm. Un moteur électrique couplé avec un réducteur (moto réducteur) convient parfaitement. Un moto réducteur permet d'obtenir de fortes capacités de couple utile par l'ajout d'une réduction mécanique.In a first embodiment of the invention, the motor M is a motor driven by electrical energy. The motor is connected to a standard electrical circuit and complies with the rules in force for the supply of power to outdoor equipment. As an example, for a 1500 kg moving bed, a climbing speed of 0.03 m / s, a pulley radius of 0.05 m at the motor shaft output, a linear acceleration of 1m / s 2 , a yield of 0.6 and a lifting distance of 2.5 m, we obtain a necessary mechanical power of the order of 75 W for a nominal torque of 125 Nm. Based on an assumption of four modules, so four electric motors, we divide by four the power necessary for each one. By admitting a factor of safety of the order from 1.5, we obtain a unit mechanical power of the order of 37.50 W for a unit torque of 41.67 Nm. An electric motor coupled with a gearbox (gear motor) is perfectly suitable. A geared motor makes it possible to obtain high useful torque capacities by adding a mechanical reduction.

Dans un second mode de réalisation, le moteur M' est animé par énergie hydraulique. Ce dernier cas autorise une puissance et un couple de fonctionnement supérieurs à une motorisation électrique ; un moteur hydraulique dispense également de prévoir des moyens de freinage aptes à bloquer le déplacement du fond mobile 3. De manière à limiter les canaux hydrauliques, on privilégie un moteur hydraulique (groupe moto pompe) indépendant pour chaque module de levage. Chaque moteur est hydrauliquement indépendant et possède sa propre réserve de fluide. Seule une alimentation électrique est à acheminer jusqu'au boîtier d'entraînement A pour le moteur pompe. A titre d'exemple, un moteur pompe convenant pour chaque module peut être de type « pompe CASAPPA série Polaris 10 » ©. Le couple développé (à 100 bar) est de 1,35 Nm. Le débit à 700 tr/mn est de 0,68 l/mn. La vitesse minimale de fonctionnement est de 650 tr/mn ce qui implique la mise en place d'un rapport de réduction de 132.In a second embodiment, the motor M 'is driven by hydraulic energy. This last case allows a power and a torque of operation higher than an electric motorization; a hydraulic motor also dispenses to provide braking means capable of blocking the displacement of the movable base 3. In order to limit the hydraulic channels, it gives preference to a hydraulic motor (motor pump unit) independent for each lifting module. Each motor is hydraulically independent and has its own supply of fluid. Only one power supply is to be routed to drive unit A for the pump motor. By way of example, a pump motor suitable for each module may be of the "CASAPPA Polaris 10 series pump" type. The developed torque (at 100 bar) is 1.35 Nm. The flow rate at 700 rpm is 0.68 l / min. The minimum operating speed is 650 rpm which implies the implementation of a reduction ratio of 132.

Le carter 1 constituant le boîtier d'entraînement A est réalisé dans un matériau rigide, suffisamment solide pour supporter le poids d'une ou de deux personnes s'appuyant dessus. Ce matériau est adapté à résister à la corrosion, par sa composition chimique, ou grâce à un traitement de surface.The housing 1 constituting the drive housing A is made of a rigid material, strong enough to support the weight of one or two people leaning on it. This material is adapted to resist corrosion, by its chemical composition, or through a surface treatment.

Le boîtier d'entraînement A comporte sur sa partie supérieure une trappe d'accès T permettant d'installer ses composants, mais également d'intervenir directement dans le mécanisme pour son dépannage ou réglage du fonctionnement.The drive housing A has on its upper part an access hatch T to install its components, but also to intervene directly in the mechanism for its troubleshooting or adjustment of operation.

Le boîtier d'entraînement A renferme également un indicateur 2, de préférence visuel, permettant d'identifier avec précision à l'endroit même du levage, la position exacte du fond mobile 3 par rapport au fond 4 de la piscine. Cet indicateur 2 de positionnement du fond mobile 3 facilite le réglage et la synchronisation des différents modules de levage 100 entre eux. Ainsi il devient possible de plaquer correctement le fond mobile 3 sur le fond 4 du bassin D lorsque celui-ci est en position basse, et cela même lorsque le fond 4 du bassin D est incliné. En position haute, dite de sécurité, le fond mobile 3 retrouve automatiquement et grâce aux réglages une assiette parfaitement horizontale.The drive housing A also encloses an indicator 2, preferably a visual indicator, which makes it possible to precisely identify, at the point of the lifting itself, the exact position of the moving base 3 with respect to the bottom 4 of the swimming pool. This positioning indicator 2 of the movable bottom 3 facilitates the adjustment and synchronization of the different lifting modules 100 between them. Thus it becomes possible to correctly plate the movable bottom 3 on the bottom 4 of the basin D when it is in the low position, and this even when the bottom 4 of the basin D is inclined. In the high position, called security, the mobile bottom 3 automatically finds and thanks to the settings a perfectly horizontal attitude.

En référence aux figures 1 et 6, l'élément de guidage B est un rail ayant la forme générale d'un profilé disposé sensiblement verticalement le long d'une paroi verticale 5 délimitant le bassin D de la piscine. Le fond mobile 3 est quant à lui pourvu de moyens de glissement et/ou de roulement 6, typiquement des billes (comme illustré à la figure 6) ou des galets maintenus à la périphérie du fond mobile 3, venant coopérer en contact avec l'élément de guidage B. L'élément de guidage B a une section de forme ondulée. Cette section est pourvue d'un renfoncement central accueillant les moyens de glissement et/ou de roulement 6, ce renfoncement central est bordé de bossages latéraux canalisant les moyens de glissement et/ou de roulement 6 lors de leur déplacement le long de l'élément de guidage. Cette forme ondulée est particulièrement adaptée à un guidage optimal du fond mobile, tout en étant extrêmement simple de conception et d'installation.With reference to figures 1 and 6 , the guide member B is a rail having the general shape of a profile disposed substantially vertically along a vertical wall delimiting the basin D of the pool. The movable base 3 is provided with sliding and / or rolling means 6, typically balls (as illustrated in FIG. figure 6 ) or rollers held at the periphery of the movable bottom 3, cooperating in contact with the guide member B. The guide member B has a corrugated section. This section is provided with a central recess accommodating the sliding and / or rolling means 6, this central recess is bordered by lateral bosses channeling the sliding and / or rolling means 6 during their movement along the element. guidance. This corrugated shape is particularly suitable for optimal guidance of the moving floor, while being extremely simple to design and install.

Comme le montre la figure 3, l'élément de guidage B est suspendu par son extrémité supérieure à une platine de fixation 7. Celle-ci est montée sur un bord supérieur de la piscine, typiquement constitué par un élément de structure de la piscine ou une margelle E. La fixation de la platine 7 sur la structure ou la margelle E peut être assurée par des vis de fixation ou par collage ou par tout moyen approprié équivalent.As shown in figure 3 , the guide member B is suspended by its upper end to a mounting plate 7. It is mounted on an upper edge of the pool, typically consisting of a structural element of the pool or a coping E. The fixation of the plate 7 on the structure or the lip E may be provided by fixing screws or by bonding or by any equivalent appropriate means.

L'élément de guidage B est relié à la platine 7 par des moyens qui peuvent être articulés, par exemple pour autoriser un conditionnement et transport aisé (l'ensemble platine - élément de guidage étant à plat ou replié sur lui-même), et pour une mise en place rapide sur le bord de la piscine (l'élément de guidage B est positionné à 90° par rapport à la platine 7). L'inclinaison à 90° entre la platine 7 et l'élément de guidage B peut être bloquée par des moyens appropriés, par exemple par un système de goupilles. Dans un autre mode de réalisation, l'élément de guidage B et la platine 7 peut être d'office rigidement fixés à 90° l'un à l'autre.The guide element B is connected to the plate 7 by means that can be articulated, for example to allow easy packaging and transport (the platinum-guide element assembly being flat or folded on itself), and for a quick installation on the edge of the pool (the guide element B is positioned at 90 ° relative to the plate 7). The inclination at 90 ° between the plate 7 and the guide element B can be blocked by appropriate means, for example by a system of pins. In another embodiment, the guide element B and the plate 7 can be automatically rigidly fixed at 90 ° to each other.

Selon l'invention, l'élément de guidage B est dépourvu de fixation avec une paroi verticale 5 contre laquelle il est accolé. L'élément de guidage B est simplement orienté pour épouser cette paroi 5. Dès lors que le fond mobile 3 est mis en place, les moyens de glissement et/ou de roulement 6 n'ont pour effet que de venir en butée contre l'élément de guidage, ce qui contribue à le plaquer contre la paroi 5 du bassin. Il n'y a pas à prévoir nécessairement des moyens de retenue de l'élément de guidage.According to the invention, the guide element B is devoid of attachment with a vertical wall 5 against which it is attached. The guide element B is simply oriented to fit this wall 5. As soon as the movable base 3 is put in place, the sliding and / or rolling means 6 only have the effect of abutting against the guiding element, which contributes to the plate against the wall 5 of the basin. It is not necessary to provide means for retaining the guide element.

L'élément de guidage est réalisé en matière inoxydable, tel que de l'inox.The guide element is made of stainless material, such as stainless steel.

Pour assurer un contact non agressif entre l'élément de guidage B et la paroi 5 du bassin D, l'élément de guidage B, peut comporter sur sa face en vis-à-vis de la paroi 5, un revêtement ou une couche 8 en matière plastique, en caoutchouc, ou en mousse (figure 3).To ensure a non-aggressive contact between the guide element B and the wall 5 of the basin D, the guide element B may comprise on its face facing the wall 5, a coating or a layer 8 made of plastic, rubber or foam ( figure 3 ).

Selon un autre aspect de l'invention, l'élément de transmission C relié au moteur M, M', est également relié au point de levage du fond mobile 3 par des moyens d'attache appropriés, afin de transmettre les efforts de traction à ce point de levage.According to another aspect of the invention, the transmission element C connected to the engine M, M ', is also connected to the lifting point of the movable base 3 by appropriate attachment means, in order to transmit the traction forces to this lifting point.

Avantageusement, l'élément de transmission C est une sangle de type « marine », en matière synthétique, par exemple en plastique ou en nylon ou analogue, particulièrement adaptée à un usage en milieu aquatique chloré. Une telle sangle présente des caractéristiques de tenue à la traction extrêmement performantes, pour une épaisseur relativement réduite, ce qui minimise son encombrement dans le boîtier d'entraînement A lorsqu'elle est enroulée.Advantageously, the transmission element C is a "marine" type strap, made of synthetic material, for example plastic or nylon or the like, particularly suitable for use in a chlorinated aquatic environment. Such a strap has extremely high tensile strength characteristics, for a relatively small thickness, which minimizes its bulk in the drive housing A when wound.

La sangle C est munie à chacune de ses extrémités d'un aménagement 13 permettant d'une part son positionnement et son ancrage sur un des éléments d'entraînement internes au boîtier d'entraînement A, et d'autre part sa fixation sur des moyens d'attache permettant de la relier au fond mobile 3.The strap C is provided at each of its ends with an arrangement 13 allowing on the one hand its positioning and its anchoring on one of the internal drive elements to the drive housing A, and secondly its attachment to fastening means for connecting to the movable bottom 3.

D'autre part, la sangle C est munie d'un ou de plusieurs éléments rapportés 14 destinés à limiter les frottements lors du cheminement le long de l'élément de guidage B.On the other hand, the strap C is provided with one or more inserts 14 intended to limit friction during the path along the guide element B.

Selon l'invention, le boîtier d'entraînement A peut être implanté de différentes façons. Selon une première variante de l'invention, illustrée à la figure 4, le boîtier A est monté extérieurement à un bord supérieur E de la piscine, de manière qu'une partie basse du boîtier A soit enterrée dans le sol, en retrait par rapport au bassin D.According to the invention, the drive housing A can be implanted in different ways. According to a first variant of the invention, illustrated in FIG. figure 4 , the housing A is mounted externally to an upper edge E of the pool, so that a lower part of the housing A is buried in the ground, set back relative to the basin D.

Selon une seconde variante de l'invention, illustrée à la figure 5, le boîtier A est monté par-dessus un bord extérieur E de la piscine. Le boîtier A peut ainsi constituer en lui-même un plot à partir duquel on peut plonger dans la piscine. Le boîtier A peut également être intégré à un plot de ce type.According to a second variant of the invention, illustrated in FIG. figure 5 , the housing A is mounted over an outer edge E of the pool. The housing A can thus constitute in itself a stud from which one can dive into the pool. The housing A can also be integrated in a stud of this type.

Un galet de renvoi 9 peut être prévu à la jonction de la platine 7 et de l'élément de guidage B, de manière à favoriser le roulement de l'élément de transmission C qui doit former un angle de renvoi dans cette zone. De la même manière, on peut prévoir un galet de renvoi 9' dans d'autres zones de passage de l'élément de transmission C, par exemple à proximité du boîtier d'entraînement A (figure 1).A return roller 9 may be provided at the junction of the plate 7 and the guide member B, so as to promote the rolling of the transmission element C which is to form a return angle in this area. In the same manner, it is possible to provide a return roller 9 'in other passage zones of the transmission element C, for example near the drive housing A ( figure 1 ).

En référence à la figure 6, les moyens de glissement et/ou de roulement 6, typiquement des billes dans l'exemple illustré, peuvent être montés mobiles dans un logement correspondant 10 ménagé à la périphérie du fond mobile 3, de manière à réaliser un rattrapage de jeu entre la paroi 5 du bassin D ces moyens 6. Dans l'exemple illustré, la bille est saillante sur environ un tiers de son diamètre. Un ressort de rappel 11 tend à repousser la bille vers le bord périphérique du fond mobile 3. Des moyens d'emprisonnement 12 sont situés à l'embouchure du logement 10 de manière à empêcher que la bille ne sorte de son logement.With reference to the figure 6 , the sliding and / or rolling means 6, typically balls in the illustrated example, can be mounted movably in a corresponding housing 10 formed at the periphery of the movable bottom 3, so as to make a clearance clearance between the wall In the illustrated example, the ball is projecting about one-third of its diameter. A return spring 11 tends to push the ball towards the peripheral edge of the movable bottom 3. The imprisoning means 12 are located at the mouth of the housing 10 so as to prevent the ball from leaving its housing.

Une autre variante d'implantation du boîtier d'entraînement A est également envisageable, comme le montre la figure 7. Le boîtier est implanté dans un logement prévu sous la margelle E de la piscine. Ce mode d'implantation nécessite toutefois une adaptation plus lourde d'une piscine existante (comparé aux implantations des figures 4 et 5), en vue de recevoir le module de levage. On peut également prévoir des repères visuels sur la margelle E ou à proximité, de manière à connaître précisément la localisation des boîtiers d'entraînement A dissimulés sous la margelle E.Another alternative embodiment of the drive housing A is also conceivable, as shown in FIG. figure 7 . The housing is located in a housing provided under the edge of the pool E. This mode of implementation, however, requires a heavier adaptation of an existing pool (compared to the locations of figures 4 and 5 ), to receive the lifting module. It is also possible to provide visual cues on the rim E or nearby, so as to know precisely the location of drive boxes A concealed beneath the lip E.

Un module de levage suivant l'invention, de part sa simplicité, et le principe même d'autonomie du module, est parfaitement adapté à une implantation sur des bassins de piscine existantes, dont les parois latérales sont sensiblement verticales, sans nécessiter des frais d'équipement, d'aménagement excessif.A lifting module according to the invention, because of its simplicity, and the very principle of autonomy of the module, is perfectly suitable for installation on existing pool basins, the side walls of which are substantially vertical, without requiring any additional cost. equipment, excessive development.

Bien entendu, l'invention n'est pas limitée aux moyens qui viennent d'être décrits et comprend tous les équivalents techniques.Of course, the invention is not limited to the means that have just been described and includes all the technical equivalents.

En particulier, l'élément de transmission peut être un câble (non illustré), en remplacement de la sangle, sans que cela remette en question d'autres caractéristiques de l'invention.In particular, the transmission element may be a cable (not shown), replacing the strap, without calling into question other features of the invention.

Concernant l'élément de guidage, on peut également prévoir que le rail B' est rapporté et fixé sur la paroi du bassin D, par exemple au moyens de vis de fixation, par collage ou par des moyens de clippage, qui le rendent notamment démontable.Regarding the guide element, it can also be provided that the rail B 'is attached and fixed to the wall of the basin D, for example by means of fixing screws, by gluing or by clipping means, which make it particularly removable .

Dans une variante de réalisation illustrée à la figure 8, la section de l'élément de guidage B' peut avoir une forme générale en C, dont une partie centrale est accolée à la paroi 5 du bassin D de la piscine. L'ouverture de cette section en C, sur toute la longueur du rail, permet le déplacement des moyens d'attache F, qui solidarisent l'extrémité basse de l'élément de transmission C au fond mobile 3, sur toute la longueur du rail.In an embodiment variant illustrated in figure 8 , the section of the guide element B 'may have a general shape C, a central portion is contiguous to the wall 5 of the pool D pool. The opening of this section C along the entire length of the rail, allows the displacement of the fastening means F, which secure the lower end of the transmission element C to the movable bottom 3, along the entire length of the rail .

L'élément de guidage B' peut être entièrement en matière plastique, souple ou rigide, compatible avec le milieu aquatique chloré. En référence à la figure 9, cet élément peut également comporter des bords ou lèvres délimitant l'ouverture du C, qui sont relativement souples, de manière à s'ouvrir lors du passage des moyens d'attache F1, et à se refermer par élasticité après leur passage. Cet effet de fermeture offre aux baigneurs une surface lisse et non agressive. Selon encore une variante (non illustrée), le corps de l'élément de guidage peut être réalisé dans un premier matériau, relativement rigide, tandis que les bords ou lèvres de l'ouverture du C sont réalisés dans un second matériau plus souple permettant leur écartement et leur fermeture sous la sollicitation des moyens d'attaches F1.The guide element B 'may be entirely made of plastic, flexible or rigid, compatible with the chlorinated aquatic environment. With reference to the figure 9 this element may also comprise edges or lips delimiting the opening of the C, which are relatively flexible, so as to open during the passage of the attachment means F1, and to close by elasticity after their passage. This closing effect offers swimmers a smooth and non-aggressive surface. According to another variant (not shown), the body of the guide element may be made of a first, relatively rigid material, while the edges or lips of the opening of the C are made of a second, softer material allowing them to spacing and their closure under the solicitation of fastening means F1.

Selon encore un autre mode de réalisation de l'invention, illustré à la figure 10, l'élément de guidage B" est positionné de manière à être noyé ou encastré dans la paroi interne 5 du bassin D. Cet agencement offre des surfaces affleurantes de l'élément de guidage B" par rapport à la paroi 5 du bassin, rendant l'élément de guidage particulièrement peu agressif pour des baigneur. Cet agencement suppose toutefois de prévoir cette intégration de l'élément de guidage dès la fabrication du bassin D de la piscine.According to yet another embodiment of the invention, illustrated in FIG. figure 10 the guide member B "is positioned to be embedded or recessed in the inner wall 5 of the pond D. This arrangement provides flush surfaces of the guide member B" relative to the wall 5 of the basin, the guiding element particularly little aggressive for bather. This arrangement however supposes to provide for this integration of the guiding element as soon as the pool D is made.
