Description

L'invention concerne un dispositif pour la manoeuvre d'une plate-forme mobile notamment pour une piscine. L'invention est plus particulièrement, mais non exclusivement, adaptée à la manoeuvre d'une plate-forme mobile adaptée à une piscine en kit ou préfabriquée, en première monte ou en installation ultérieure, et plus particulièrement avantageuse pour l'installation d'une plate-forme mobile dans une piscine, dite miroir, où l'eau affleure les bords. L'invention est également avantageuse pour la réalisation d'un dispositif à plate-forme mobile dans une piscine ou un bac de petite dimension, même particulièrement profond telle qu'une fosse à plongeon ou de plongée.The invention relates to a device for operating a mobile platform, in particular for a swimming pool. The invention is more particularly, but not exclusively, adapted to the operation of a mobile platform adapted to a pool kit or prefabricated, original equipment or subsequent installation, and more particularly advantageous for the installation of a mobile platform in a pool, called mirror, where the water is flush with the edges. The invention is also advantageous for the realization of a mobile platform device in a pool or a small tank, even particularly deep such as a diving pit or diving.

Un tel fond mobile est utilisé dans un bassin pour en moduler la profondeur, ou plus simplement pour occulter ledit bassin afin de l'isoler des salissures extérieures, maintenir la température de l'eau ou assurer la sécurité vis-à-vis des jeunes enfants.Such a movable floor is used in a basin to modulate the depth, or more simply to hide the said basin to isolate it from external soils, maintain the temperature of the water or ensure safety vis-à-vis young children .

L'invention est également adaptable à tout bac industriel équipé d'une plate-forme mobile tel qu'un bac de trempe, un bac de produit de traitement chimique ou un bac de peinture.The invention is also adaptable to any industrial tray equipped with a mobile platform such as a quenching tank, a tank of chemical treatment product or a paint tray.

Les documents FR 2 920 455 , US 3 091 777 , US 3 668 711 et US 5 42 502 décrivent des dispositifs de levage d'un fond de piscine utilisant des dispositifs de traction à base de câbles ou de sangles. Au cours du déplacement de ces fonds mobiles, lesdits fonds sont soumis à des effets hydrodynamiques qui entraînent des mouvements latéraux du fond dans un plan sensiblement horizontal. De même, lorsque le fond est arrêté dans une position définie, l'usage de la piscine est également susceptible d'entraîner des mouvements latéraux du fond. Lorsque ledit fond est apte à servir de terrasse en position haute et qu'il présente par conséquent une certaine masse, de tels mouvements, même de faible amplitude sont aptes à conférer à la plate-forme constituant le fond mobile une énergie cinétique suffisante pour dégrader les parois de la piscine si elle entre en collision avec celles-ci au cours de ces mouvements. Ainsi, tous ces dispositifs de l'art antérieur nécessitent la mise en place d'éléments de guidage et d'arrêt sur les parois de la piscine, lesquels éléments de guidage ont pour fonction de contrer les mouvements latéraux de la plate-forme constituant le fond mobile afin d'éviter que ladite plate-forme n'entre en collision avec les parois de la piscine au cours de tels mouvements latéraux, ce qui aurait pour conséquence de dégrader le revêtement, plus particulièrement lorsque ledit revêtement est un chemisage par un film plastique ou liner. Selon ces solutions de l'art antérieur, ce guidage est obtenu par la reprise, par les parois de la piscine, des efforts correspondant au blocage de ces mouvements latéraux. Cet appui local n'est pas toujours compatible avec la nature de la piscine dont les parois ne disposent pas toujours de la rigidité suffisante pour reprendre ce type d'effort, plus particulièrement lorsque le guidage est en milieu de paroi. La réalisation de guidages dans la maçonnerie implique des modifications importantes du bassin avec la destruction provisoire du revêtement d'étanchéité, puis des difficultés pour réaliser à nouveau cette étanchéité. Finalement les solutions de l'art antérieur nécessitent un ajustement précis des dimensions de la plate-forme et des dispositifs, notamment de guidage, associés, qui doivent être réalisés sur mesure et ne sont que très difficilement ajustables sur site, et quel que soit le soin apporté à la réalisation, il subsistera toujours des jeux, entraînant des sollicitations des parois selon des modes de chargement pour lesquels elles ne sont pas initialement conçues. De plus les exemples de réalisation de l'art antérieur, et comportent fréquemment des éléments de manoeuvre et de guidage, tels que des câbles, des sangles ou des profilés qui restent apparents et inesthétiques dans le bassin après installation et peuvent même provoquer des blessures aux personnes évoluant dans ledit bassin.The documents FR 2 920 455 , US 3,091,777 , US 3,668,711 and US 5 42 502 describe lifting devices for a pool floor using traction devices based on cables or straps. During the displacement of these mobile funds, said funds are subject to hydrodynamic effects which cause lateral movements of the bottom in a substantially horizontal plane. Similarly, when the bottom is stopped in a defined position, the use of the pool is also likely to cause lateral movements of the bottom. When said bottom is able to serve as a terrace in the high position and therefore has a certain mass, such movements, even small amplitude are able to give the platform constituting the mobile background kinetic energy sufficient to degrade the walls of the pool if it collides with them during these movements. Thus, all these devices of the prior art require the establishment of guide and stop elements on the walls of the pool, which guide elements have the function of counteracting the lateral movements of the pool. platform constituting the movable bottom to prevent said platform from colliding with the walls of the pool during such lateral movements, which would have the effect of degrading the coating, especially when said coating is a liner with a plastic film or liner. According to these solutions of the prior art, this guidance is obtained by the recovery, by the walls of the pool, efforts corresponding to the blocking of these lateral movements. This local support is not always compatible with the nature of the pool whose walls do not always have sufficient rigidity to take this type of effort, especially when the guide is in the middle of the wall. The realization of guidance in the masonry involves major modifications of the basin with the temporary destruction of the waterproofing coating, then difficulties in achieving this seal again. Finally, the solutions of the prior art require a precise adjustment of the dimensions of the platform and associated devices, including guidance, which must be made to measure and are very difficult to adjust on site, and whatever the care taken to the realization, there will always remain games, causing stresses of the walls according to modes of loading for which they are not initially designed. In addition, the examples of embodiment of the prior art, and often include maneuvering and guiding elements, such as cables, straps or profiles which remain apparent and unsightly in the basin after installation and may even cause injuries to the people moving in said basin.

L'invention vise à résoudre les inconvénients de l'art antérieur et concerne à cette fin, un module de guidage, apte à être installé dans un bac et comprenant :

  • i. un profilé, dit de stabilisation, comportant une membrure de guidage, délimitant un volume, dit volume interne, à l'intérieur de la section dudit profilé ;
  • ii. un filin de traction, s'étendant à l'intérieur du volume interne sur une longueur égale ou supérieure à la longueur l de guidage ;
  • iii. des moyens d'accrochage, comportant :
    • une platine, dite de levage, comportant des moyens de fixation de la première extrémité du filin de traction ;
    • un galet de guidage en liaison pivot par rapport à ladite platine de levage comportant un profil complémentaire à la membrure de guidage et apte à rouler sur ladite membrure lorsque la platine se déplace en translation par rapport au profilé de stabilisation.
  • iv. de moyens de manoeuvre pour appliquer une traction à la seconde extrémité du filin de traction.
The invention aims to solve the disadvantages of the prior art and concerns for this purpose, a guide module, adapted to be installed in a tray and comprising:
  • i. a profile, said stabilization, comprising a guide member, defining a volume, said internal volume, within the section of said profile;
  • ii. a pull wire, extending inside the inner volume of a length equal or greater than the length of the guide;
  • iii. fastening means, comprising:
    • a plate, said lifting, having means for fixing the first end of the traction rope;
    • a guide roller pivotally connected to said lifting plate having a profile complementary to the guide frame and adapted to roll on said frame when the plate moves in translation relative to the stabilizing section.
  • iv. actuating means for applying traction to the second end of the traction rope.

Ainsi, l'installation d'un fond mobile est simplement réalisée en connectant ledit fond mobile aux platines d'une pluralité de modules de guidage selon l'invention, lesquels modules sont judicieusement disposés, en nombre adéquat dans le bassin, préférentiellement un module dans chaque coin.Thus, the installation of a moving bottom is simply carried out by connecting said movable bottom to the plates of a plurality of guide modules according to the invention, which modules are judiciously arranged, in adequate number in the basin, preferably a module in every corner.

L'invention concerne également un dispositif de relevage d'une plate-forme mobile dans un bac lequel dispositif comporte un module de guidage selon l'invention et dans lequel les moyens de manoeuvre comprennent un filin de manoeuvre s'étendant entre un treuil et un ancrage fixe, et passant entre les deux par un moufle. Ainsi l'effort de traction fournit par le treuil est réduit.The invention also relates to a lifting device of a mobile platform in a container which device comprises a guide module according to the invention and in which the operating means comprise an operating wire extending between a winch and a fixed anchorage, and passing between the two by a muffle. Thus the traction force provided by the winch is reduced.

Avantageusement, l'ancrage est connecté à un point fixe par l'intermédiaire d'une liaison élastique et comporte des moyen aptes à mesure la déformation de ladite liaison élastique. Ainsi, la tension du filin, sous l'effet de la force de traction, divisée par la présence du moufle, est mesurée au cours de la manoeuvre ce qui permet de la maintenir entre des valeurs déterminées et notamment de détecter des blocages et de stopper en ce cas le dispositif de levage pour la sécurité des biens et des personnes.Advantageously, the anchor is connected to a fixed point by means of an elastic connection and comprises means capable of measuring the deformation of said elastic connection. Thus, the tension of the rope, under the effect of the tensile force, divided by the presence of the muffle, is measured during the maneuver which allows to maintain it between specific values and in particular to detect blockages and stop in this case the lifting device for the safety of goods and people.

Selon un mode particulier du dispositif objet de l'invention :

  1. a. le filin de traction s'enroule sur une poulie de levage, d'axe horizontal, pour passer d'une direction horizontale à une direction verticale ;
  2. b. le filin de manoeuvre et le moufle exercent une traction sensiblement horizontale sur la deuxième extrémité du filin de traction, selon une course horizontale.
According to a particular embodiment of the device which is the subject of the invention:
  1. at. the traction rope is wound on a hoisting pulley, of horizontal axis, to move from a horizontal direction to a vertical direction;
  2. b. the operating rope and the muffle exert a substantially horizontal traction on the second end of the traction rope, in a horizontal race.

Ainsi le dispositif de traction horizontal est avantageusement installé au sommet et sur le périmètre du bac.Thus the horizontal traction device is advantageously installed at the top and on the perimeter of the tank.

Avantageusement, le filin de manoeuvre est constitué d'une tresse tubulaire. Ainsi, ladite tresse, de par sa constitution, est apte à s'enrouler sur des rayons de courbures réduits sans être dégradée ce qui permet de réduire manière importante les diamètres des poulies, et par suite l'encombrement du dispositif.Advantageously, the operating wire consists of a tubular braid. So, said braid, by its constitution, is able to curl on reduced radii of curvature without being degraded which allows to significantly reduce the diameter of the pulleys, and therefore the size of the device.

L'invention est avantageusement mise en oeuvre selon les modes de réalisation exposés ci-après, lesquels sont à considérer individuellement ou selon toute combinaison techniquement opérante.The invention is advantageously implemented according to the embodiments described below, which are to be considered individually or in any technically operative combination.

Avantageusement, le filin de traction est également constitué d'une tresse tubulaire. Ainsi le diamètre de la poulie de levage est également réduit.Advantageously, the traction rope also consists of a tubular braid. Thus the diameter of the lifting pulley is also reduced.

Avantageusement, la tresse tubulaire comprend des fibres de para-aramide. De telles fibres, telles que constituées de poly-para-phénylène téréphtalamide ou Kevlar® confèrent au filin une résistance mécanique élevée et leurs propriétés de frottement avantageuses limitent l'usure et permettent un fonctionnement silencieux du dispositif.Advantageously, the tubular braid comprises para-aramid fibers. Such fibers, such as made of poly-para-phenylene terephthalamide or Kevlar® give the rope a high mechanical strength and their advantageous friction properties limit wear and allow quiet operation of the device.

Selon un mode de réalisation avantageux, le moufle exerce une traction sur deux filins de manoeuvre. Ainsi l'encombrement et le coût de réalisation d'une installation intégrant de tels dispositifs de relevage sont réduits.According to an advantageous embodiment, the muffle exerts traction on two operating lines. Thus the size and cost of realization of an installation incorporating such lifting devices are reduced.

L'invention concerne également un bac sensiblement rectangulaire, comportant une plate-forme mobile et deux dispositifs selon le mode de réalisation précédent pour le relevage de ladite plate-forme, dans lequel, chaque dispositif de relevage exerce une traction sur deux coins opposés selon la diagonale de la plate-forme. Cette configuration permet de réaliser un dispositif très compact intégré au bac, même si le périmètre dudit bac est réduit en regard de sa profondeur.The invention also relates to a substantially rectangular tray, comprising a mobile platform and two devices according to the preceding embodiment for lifting said platform, wherein, each lifting device exerts traction on two opposite corners according to the diagonal of the platform. This configuration allows for a very compact device integrated in the tray, even if the perimeter of said tray is reduced with respect to its depth.

Avantageusement, chaque coin du bac objet de l'invention comporte une platine de guidage comportant deux paires de poulies d'axe vertical pour le guidage selon des directions parallèles d'un filin de traction de chaque dispositif de relevage. La dimension réduite des poulies permet d'intégrer ces ensembles dans l'épaisseur des parois du bac.Advantageously, each corner of the tray object of the invention comprises a guide plate having two pairs of vertical axis pulleys for guiding in parallel directions of a traction rope of each lifting device. The reduced size of the pulleys makes it possible to integrate these assemblies in the thickness of the walls of the tank.

Avantageusement, les filins de manoeuvre et de traction cheminent dans une goulotte de largeur inférieure ou égale à la largeur des parois du bac, s'étendant en partie supérieure sur le périmètre dudit bac. Ladite goulotte est réalisée de matière avec le bac, ou rapportée sur celui-ci. Le faible encombrement latéral du dispositif de levage selon l'invention permet d'intégrer celui-ci dans une goulotte de faible largeur.Advantageously, the maneuvering and traction cables run in a trough of width less than or equal to the width of the walls of the trough, extending in the upper part on the perimeter of said trough. Said chute is made of material with the tray, or reported thereon. The small lateral dimensions of the lifting device according to the invention makes it possible to integrate it into a narrow width of the trough.

Selon un mode de réalisation avantageux, ladite goulotte est constituée par un assemblage d'éléments modulaires. Ainsi, l'installation d'un tel dispositif sur un bac existant, par exemple une piscine, est grandement facilitée.According to an advantageous embodiment, said chute is constituted by an assembly of modular elements. Thus, the installation of such a device on an existing tank, for example a swimming pool, is greatly facilitated.

Selon un exemple de réalisation avantageux représenté figure 1, un dispositif de plate-forme mobile, adapté à un bac (100) comporte une plate-forme (110) s'étendant dans un plan (xy) sensiblement horizontal, des moyens (120) de guidage du déplacement vertical de la plate-forme (110) dans ledit bac et des moyens de manoeuvre comprenant des moyens (130) de motorisation. Lesdits moyens (130) de motorisation agissent, par exemple, par l'intermédiaire d'un treuil, sur un filin de traction constitué d'un câble, d'une corde ou d'une sangle.According to an advantageous embodiment shown figure 1 a movable platform device, adapted to a trough (100), comprises a platform (110) extending in a substantially horizontal plane (xy), means (120) for guiding the vertical displacement of the platform form (110) in said tray and operating means comprising means (130) for motorization. Said motorization means (130) act, for example, via a winch, on a traction rope consisting of a rope, a rope or a strap.

Figure 2, selon un exemple de réalisation, le filin de traction (230) est connecté à sa première extrémité (231) à la plate-forme (110) et à sa seconde extrémité (232) au treuil. Selon cet exemple de réalisation, la traction appliquée à la seconde (232) extrémité du filin (230) de traction est orientée selon une direction (x) horizontale, cette traction ayant pour effet de produire un déplacement vertical, selon z, de la plate-forme (110) mobile. À cette fin, ledit filin (230) est orienté de la direction horizontale à la direction verticale par le réa (240) d'une poulie dont la chape est fixée à une paroi du bac (100). Le diamètre du réa (240) de la poulie est fonction du rayon de courbure que peut supporter le filin (230) de traction. Aussi, pour permettre un relevage de la plate-forme mobile jusqu'à une hauteur où elle affleure la partie supérieure de la paroi du bac (100), ladite poulie fait saillie, par rapport au sommet de la paroi, d'une valeur au moins égale au rayon de ladite poulie. Figure 2 according to an exemplary embodiment, the traction rope (230) is connected at its first end (231) to the platform (110) and at its second end (232) to the winch. According to this embodiment, the traction applied to the second (232) end of the traction rope (230) is oriented in a horizontal direction (x), this traction having the effect of producing a vertical displacement, according to z, of the plate -form (110) mobile. At this Finally, said rope (230) is oriented from the horizontal direction to the vertical direction by the sheave (240) of a pulley whose yoke is fixed to a wall of the tray (100). The diameter of sheave (240) of the pulley is a function of the radius of curvature that can support the tow (230) traction. Also, to allow a lifting of the mobile platform to a height where it is flush with the upper part of the wall of the tray (100), said pulley projects, relative to the top of the wall, a value at less than the radius of said pulley.

Figure 3, avantageusement, le filin (230) est un câble ou une corde, ainsi, le dispositif utilise un moufle (350) pour la traction du fond mobile ce qui permet de multiplier la force de traction. Ainsi, selon cet exemple de réalisation, le filin de traction (230) est connecté à un dispositif de manoeuvre à sa seconde (232) extrémité, en passant par une poulie (341) de renvoi d'angle. Selon, cet exemple de réalisation, ledit dispositif de manoeuvre comprend un filin (330) de manoeuvre, relié à l'une de ses extrémités (332) à un dispositif de traction tel qu'un treuil, et à son autre extrémité (331) à un ancrage (360). La connexion de ce filin (330) de manoeuvre avec le filin (230) de traction est réalisée par un moufle (350). Selon cet exemple de réalisation, ledit moufle (350) comprend deux poulies (351, 352), et le filin (330) de manoeuvre s'enroule successivement autour de ces deux poulies (351, 352) en passant par une poulie (342) intermédiaire fixe. Ainsi, selon cet exemple de réalisation, pour un effort de traction d'intensité T1 appliqué par le filin (230) de traction sur la plate-forme, un effort de traction T2 = T1/4 est appliqué à la seconde (332) extrémité du filin (330) de manoeuvre. Un effort égal en intensité à T2 est également appliqué à l'ancrage (360) selon une direction parallèle au filin (330) de manoeuvre à cette extrémité (331). Ainsi ce mécanisme de moufle permet de réduire par un facteur 4 la force de traction T2 appliquée au filin (330) de manoeuvre en regard de la force de traction T1 appliquée sur la plate-forme mobile. En contrepartie le déplacement de l'extrémité (332) du filin (330) de manoeuvre est 4 fois plus important que l'extrémité (231) du filin (230) de traction et la course du moufle (350) au cours du déplacement de la plate-forme sur toute la hauteur du bac est égale à cette hauteur. Avantageusement, ladite course du moufle (350) est réalisée dans un plan horizontal, ce qui permet de dissimuler le mécanisme de manoeuvre sur les bords du bac, par exemple, dans les margelles d'une piscine. Selon cet exemple de réalisation l'ancrage est réalisé par l'intermédiaire d'une liaison élastique, par exemple au moyen d'un ressort (361) hélicoïdal. Ainsi, le dit ressort est, selon cet exemple de réalisation, comprimé en fonction de l'intensité de l'effort de traction T2. La simple mesure de la longueur dudit ressort (361) comprimé, permet d'obtenir une information proportionnelle à cet effort de traction, puis, par exemple d'utiliser cette information pour arrêter le relevage de la plate-forme en cas de blocage. Figure 3 Advantageously, the rope (230) is a rope or a rope, thus, the device uses a muffle (350) for the traction of the movable bottom which makes it possible to multiply the traction force. Thus, according to this exemplary embodiment, the traction rope (230) is connected to an operating device at its second (232) end, passing through a pulley (341) of angle gear. According to this exemplary embodiment, said maneuvering device comprises a maneuvering rope (330) connected at one of its ends (332) to a traction device such as a winch, and at its other end (331). at an anchorage (360). The connection of this rope (330) of maneuvering with the rope (230) of traction is carried out by a muffle (350). According to this embodiment, said muffle (350) comprises two pulleys (351, 352), and the operating wire (330) is wound successively around these two pulleys (351, 352) via a pulley (342). fixed intermediate. Thus, according to this exemplary embodiment, for a traction force of intensity T 1 applied by the traction rope (230) to the platform, a traction force T 2 = T 1/4 is applied to the second ( 332) end of the rope (330) maneuvering. A force equal intensity T 2 is also applied to the anchoring (360) in a direction parallel to the wire (330) of maneuver at this end (331). Thus this muffle mechanism reduces by a factor 4 the tensile force T 2 applied to the actuating rope (330) facing the tensile force T 1 applied to the mobile platform. In counterpart, the displacement of the end (332) of the maneuvering rope (330) is 4 times greater than the end (231) of the traction rope (230) and the movement of the muffle (350) during the displacement of the platform over the entire height of the tray is equal to this height. Advantageously, said race muffle (350) is made in a horizontal plane, which allows to hide the operating mechanism on the edges of the tray, for example, in the edges of a pool. According to this embodiment, the anchoring is carried out by means of an elastic connection, for example example by means of a helical spring (361). Thus, said spring is, according to this embodiment, compressed according to the intensity of the tensile force T 2 . The simple measurement of the length of said compressed spring (361) makes it possible to obtain information proportional to this tensile force, and then, for example, to use this information to stop lifting the platform in the event of a blockage.

En revenant à la figure 1, lorsque, par exemple, la plate-forme (110) mobile est commandée par un dispositif de levage dans chacun de ses quatre coins, alors ledit mécanisme comporte selon cet exemple de réalisation, deux dispositifs (130) de manoeuvre, comportant chacun deux moufles, dont la course est parallèle à l'un des côtés du bac. Ces dispositifs sont dissimulés dans un carter, dont les dimensions sont suffisantes pour accueillir lesdits dispositifs et leur course. Ainsi cet encombrement est notamment fonction du diamètre des poulies du mécanisme de manoeuvre (341, 342, 351, 352, figure 3) et des courses nécessaire. Aussi lorsque la profondeur du bac est importante en regard du périmètre du bac, le dispositif de manoeuvre est difficile à installer.Returning to figure 1 when, for example, the mobile platform (110) is controlled by a lifting device in each of its four corners, then said mechanism comprises according to this embodiment, two devices (130) for maneuvering, each comprising two mittens , whose course is parallel to one side of the tank. These devices are hidden in a housing, the dimensions of which are sufficient to accommodate said devices and their stroke. Thus this space is in particular a function of the diameter of the pulleys of the operating mechanism (341, 342, 351, 352, figure 3 ) and necessary shopping. Also when the tank depth is important next to the perimeter of the tank, the operating device is difficult to install.

Figure 4, selon un exemple de réalisation le bac (400) objet de l'invention est un bac préfabriqué en béton ou en matière plastique. Ledit bac (400) comporte une plate-forme mobile (410) laquelle est déplacée au moyen d'un dispositif de levage, intégré au bac. Alternativement le bac (400) est constitué par l'assemblage d'éléments modulaires. Selon le mode de réalisation de la figure 4, le dispositif de relevage comprend des moyens de manoeuvre (430) comprenant des moyens de motorisation et un treuil, lesquels moyens de manoeuvre sont placés dans un carter (450) intégré aux parois du bac et réalisent le relevage par l'intermédiaire de deux filins de manoeuvre et de quatre filins de traction, ces derniers agissant sur la plate-forme (410) mobile dans les quatre coins de cette plate-forme. Lesdits filins sont constitués d'une tresse tubulaire de fibres de para-aramide et sont logés dans une goulotte (480) intégrée au bac (400) selon cette exemple de réalisation, et fermée par des margelles. De telles tresses tubulaires sont réalisées par tressage d'une pluralité de brins selon au moins deux orientations. Sans être lié par une quelconque théorie, il semble que la capacité de déformation relative de la section de la tresse au passage des poulies, permet à celle-ci de suivre des rayons de courbure très serrés. Le guidage des filins de traction et des filins de manoeuvre est réalisé par des poulies dont l'axe du réa est vertical et installées sur des platines (460) fixées dans les coins du bac (400). En cas d'installation sur un bac existant, ou lorsque ledit bac est réalisé par un assemblage d'éléments modulaires, ladite goulotte (480) est réalisée par l'assemblage d'éléments modulaire de section en U, par exemple en béton, similaire à des parpaings de chaînage ou en matière plastique.Figure 4, according to an exemplary embodiment the tray (400) object of the invention is a prefabricated tray made of concrete or plastic. Said tank (400) comprises a movable platform (410) which is moved by means of a lifting device, integrated in the tray. Alternatively the tray (400) is constituted by the assembly of modular elements. According to the embodiment of FIG. 4, the lifting device comprises maneuvering means (430) comprising motorization means and a winch, which operating means are placed in a casing (450) integrated with the walls of the tank and realize lifting by means of two drive lines and four traction lines, the latter acting on the platform (410) movable in the four corners of this platform. Said ropes consist of a tubular braid of para-aramid fibers and are housed in a trough (480) integrated in the trough (400) according to this embodiment, and closed by curbs. Such tubular braids are made by braiding a plurality of strands in at least two orientations. Without being bound by any theory, it seems that the capacity of relative deformation of the section of the braid to the passage of the pulleys, allows it to follow very tight radii of curvature. The guidance of the traction and maneuvering lines is carried out by means pulleys whose axis of the sheave is vertical and installed on plates (460) fixed in the corners of the tray (400). In the case of installation on an existing tank, or when said tank is made by an assembly of modular elements, said chute (480) is made by the assembly of modular U-section elements, for example made of concrete, similar to blocking blocks or plastic.

Figure 5, chaque platine (460) comporte une pluralité de poulies (561, 562) d'axe vertical (z). Selon cet exemple de réalisation, la platine comporte une paire de poulies (562) dite paire interne, et une paire de poulies (561), dite paire externe, les centres des poulies de chaque paire étant sensiblement alignés parallèlement à l'arête de la platine (460). Lesdites poulies sont avantageusement constituées d'une matière plastique et sont sensiblement en forme de diabolo. Avantageusement, deux poulies sont superposées sur chaque axe vertical. Selon cet exemple de réalisation Une poulie (540) de relevage est placée en face de chaque platine (460) pour transmettre, selon une direction verticale (z), la traction du filin de traction à la plate-forme mobile. Ainsi, jusqu'à l'arrivée du filin de traction sur la poulie de relevage, les tractions appliquées aux filins de traction et de manoeuvre ainsi que la course des moufles sont réalisées selon un plan horizontal. L'utilisation d'une tresse tubulaire comme filin permet de réduire les rayons des poulies (561, 562, 540) sans risque de dégradation dudit filin. De plus, l'utilisation d'une telle tresse permet la réalisation facile d'épissures peu encombrantes notamment pour le raccordement des moufles avec les filins de traction. Ainsi, l'ensemble du mécanisme de manoeuvre occupe une faible hauteur et une faible largeur au sommet du bac. Figure 5 each plate (460) has a plurality of pulleys (561, 562) of vertical axis (z). According to this embodiment, the plate comprises a pair of pulleys (562) called inner pair, and a pair of pulleys (561), said outer pair, the centers of the pulleys of each pair being substantially aligned parallel to the edge of the platinum (460). Said pulleys are advantageously made of a plastic material and are substantially diabolo-shaped. Advantageously, two pulleys are superimposed on each vertical axis. According to this embodiment A lifting pulley (540) is placed in front of each plate (460) to transmit, in a vertical direction (z), traction traction rope to the mobile platform. Thus, until the arrival of the traction rope on the lifting pulley, the traction applied to the traction and maneuvering ropes and the race of the mittens are carried out in a horizontal plane. The use of a tubular braid as a rope makes it possible to reduce the radii of the pulleys (561, 562, 540) without the risk of degradation of said rope. In addition, the use of such a braid allows the easy realization of space-saving splices, especially for connecting the mittens with the traction lines. Thus, the entire operating mechanism occupies a small height and a small width at the top of the tray.

Figure 6, selon cet exemple de réalisation, le filin de traction agit sur une platine (615) d'accrochage placée sous la plate-forme mobile et liée à celle-ci, laquelle platine d'accrochage comporte un galet (611) en forme de diabolo, lequel galet roule sur un profilé (612) de stabilisation comportant une membrure de guidage de section complémentaire audit galet (612), et installé dans un angle du bac, ladite membrure de guidage faisant saillie par rapport à l'angle du bac. La poulie (540) de levage est placée au sommet dudit profilé (612) de stabilisation, et le filin de traction chemine depuis cette poulie (540) jusqu'à son ancrage sur la platine (615) d'accrochage entre le coin du bac et la face interne de la membrure de guidage. Ainsi, le faible diamètre de la poulie (540) de levage permet de placer le sommet de celle-ci au niveau de l'eau contenue dans le bac sans limiter la hauteur de remontée de la plate-forme. Ainsi, le dispositif objet de l'invention est adapté à la réalisation d'une piscine miroir ou à débordement. Figure 6 , according to this embodiment, the traction rope acts on a plate (615) hooking placed under the mobile platform and connected thereto, which attachment plate comprises a roller (611) shaped diabolo , which roller rolls on a stabilizing section (612) comprising a guide member of complementary section to said roller (612), and installed in an angle of the tray, said guide member protruding from the angle of the tray. The lifting pulley (540) is placed at the top of said stabilizing section (612), and the traction rope travels from this pulley (540) to its anchorage on the plate (615) for hooking between the corner of the tray and the inner face of the guide chord. Thus, the small diameter of the lifting pulley (540) makes it possible to place the top of it at the level of the water contained in the tank without limiting the height of the platform. Thus, the device that is the subject of the invention is suitable for producing a mirror or overflow pool.

Figure 7, selon un exemple de réalisation le dispositif de levage du fond mobile comprend un treuil comportant deux tambours sur lesquels sont enroulés deux filins (731, 732) de manoeuvre selon un sens d'enroulement opposé. Chaque filin (731, 732) de manoeuvre quitte le treuil est s'enroule autour de la poulie (751, 752) d'un moufle, l'autre extrémité dudit filin étant liée à un point fixe (761, 762). Lors du cheminement des treuils vers les moufles (751, 752), lesdits filins de manoeuvre sont guidés sur les s trains de poulies (561) à axe vertical placé le long de l'arête externe des platines de guidage installées dans les coins du bassin (400). Chaque moufle (751, 752) est connecté à l'extrémité de deux filins (771, 773, 772, 774) de traction superposés verticalement. Un premier (771, 772) filin de traction est connecté à la plate-forme mobile par l'intermédiaire d'une poulie (540) de relevage située dans le coin le plus proche du moufle (751, 752). Le deuxième (773, 774) filin s'étend en passant par les trains de poulie des platines de guidage jusqu'à l'angle opposé par rapport à la diagonale du bassin, où il est connecté à la plate-forme par l'intermédiaire d'une poulie (540) de relevage. Figure 7 , according to an exemplary embodiment the lifting device of the movable bottom comprises a winch having two drums on which are wound two running ropes (731, 732) in an opposite winding direction. Each rope (731, 732) maneuvering leaves the winch is wrapped around the pulley (751, 752) of a muffle, the other end of said rope being connected to a fixed point (761, 762). When moving the winches to the mittens (751, 752), said drive lines are guided on the pulley trains (561) with a vertical axis placed along the outer edge of the guide plates installed in the corners of the basin (400). Each muffle (751, 752) is connected at the end of two vertically superimposed towing lines (771, 773, 772, 774). A first traction rope (771, 772) is connected to the movable platform via a lifting pulley (540) located in the nearest corner of the muffle (751, 752). The second (773, 774) rope extends through the pulley trains of the guide plates to the opposite angle with respect to the diagonal of the basin, where it is connected to the platform via a lifting pulley (540).

La description ci-avant et les exemples de réalisation montrent que l'invention atteint les objectifs visés. En particulier elle permet la réalisation d'un dispositif très compact pour le levage d'une plate-forme mobile, lequel dispositif est facilement intégré dans un bac préfabriqué ou sous les margelles d'une piscine existante sans gros travaux de maçonnerie.The above description and the exemplary embodiments show that the invention achieves the desired objectives. In particular it allows the realization of a very compact device for lifting a mobile platform, which device is easily integrated in a prefabricated tank or under the edges of an existing pool without major masonry work.
