Description

FOND MOBILE POUR PISCINE MOBILE BACKGROUND FOR SWIMMING POOL

DOMAINE TECHNIQUE DE L'INVENTION [0001] Le domaine technique de l'invention est celui des bâtiments ou constructions similaires destinés à un emploi particulier tels que des piscines ou pataugeoires, et a plus particulièrement pour objet un dispositif de fond mobile d'une telle construction. ETAT DE LA TECHNIQUE ANTERIEURE [0002] La problématique des fonds mobiles de piscines, de pataugeoires ou de constructions similaires connaît déjà plusieurs dispositifs, notamment celui de la mise en place d'un moyen de portance d'un fond de piscine ou pataugeoire tel que des moyens de levage par câbles ou de bras articulés situés à un niveau inférieur audit fond de la piscine et aptes d'une part, à le supporter, et d'autre part, à le translater verticalement. [0003] A ce titre, on connaît la demande de brevet d'invention EP1174569 Al qui décrit un dispositif de sol mobile vertical pour une piscine ou une construction similaire. Plus particulièrement ce système décrit un dispositif comportant un sol mobile apte à être entrainé verticalement comportant des moyens de flottaison, un moyen de levage dudit sol le long des murs latéraux, un moyen de stabilisation dudit sol, ledit moyen de levage étant caractérisé en ce qu'il comprend un système de levage par chaines, motorisé et disposé latéralement à la piscine et assisté de bras de levage apte à sécuriser le mouvement dudit sol mobile de la piscine. [0004] inconvénients, élevé, d'autre câbles, de ne notamment aux leur longueur, Des tels dispositifs ont notamment les d'une part, de nécessiter un coût d'entretien part, dans le cas d'une solution utilisant des pas permettre un fonctionnement uniforme dû renvois des câbles, à leur allongement et à et enfin, ce dispositif volumineux nécessite des moteurs de forte puissance ainsi que la présence d'un local technique important à proximité. EXPOSE DE L'INVENTION [0005] Le dispositif décrit par la suite vise à remédier aux inconvénients de l'état de la technique et notamment à réaliser de manière simple et fiable un fond mobile de piscine ou pataugeoire muni d'un dispositif de fond mobile amélioré. [0006] A cet effet, l'invention a pour objet un 10 dispositif de fond mobile d'une piscine comprenant un fond fixe et des murs latéraux dressés, ce dispositif comportant : - un sol mobile ; - au moins un moyen de traction vers le haut dudit sol mobile apte à créer un effort dont une composante principale 15 est dirigée vers le haut et comprenant un entraineur et un câble ; caractérisé en ce que lesdits moyens de traction comprennent au maximum un renvoi de câble, par câble. [0007] Est entendu comme étant un renvoi tout organe 20 de transmission de mouvement changeant la direction de celui-ci, en particulier du câble. [0008] Il est entendu également qu'un entraineur est un moyen d'entrainement du câble, motorisé ou non. [0009] Selon une caractéristique particulière ledit 25 câble présente une première extrémité fixée audit sol mobile et une seconde extrémité fixée à la piscine. De façon avantageuse ledit entraineur est fixé à la piscine et comprend la seconde extrémité constituant une réserve de câble. 30 [0010] L'entraineur, situé en surface de la piscine, est donc apte à enrouler et dérouler le câble. De ce fait, la disposition de multiples moyens de tractions en périmétrie de la piscine permet, par l'action des entraineurs, de créer une force de traction sur les câbles et ainsi de monter le sol 35 mobile. A l'inverse, lorsque les entraineurs inversent cet effort de traction, cela permet la descente du sol mobile. [0011] Selon une autre caractéristique, ladite fixation de la première extrémité est située en périmétrie dudit sol mobile. Cela permet d'une part, d'améliorer la stabilité du sol mobile lors de son déplacement et, d'autre part, d'améliorer l'efficacité de l'action de l'entraineur. [0012] Lors d'une modification d'état du sol mobile et plus précisément d'un état statique à un état levé, l'entraineur, qu'il soit motorisé ou manuel, doit vaincre un effort d'inertie au démarrage dû au poids du sol mobile. Afin de limiter ce effort, le sol mobile comprend des moyens de flottaison permettant de soulager en partie l'effet du poids dudit sol mobile et ainsi de vaincre cet inertie de démarrage. En effet, dans le cas d'un entraineur motorisé, cela permet d'utiliser, par exemple, des motrices basses tensions compatibles avec un approvisionnement d'énergie solaire, et dans le cas d'un entraineur manuel, de soulager l'effort à fournir, par exemple dans la mise en rotation d'une manivelle. [0013] Avantageusement, le dispositif de fond mobile pour piscine comprend des moyens de guidage et/ou de blocage dudit sol mobile vis-à-vis desdits murs latéraux, ces moyens de guidage et/ou de blocage étant situés en périmétrie dudit sol mobile. Ceci, d'une part, dans le but de permettre de guider la montée et la descente et du sol mobile et, d'autre part, d'en assurer le blocage à la profondeur choisie. Ces moyens de guidage pouvant être notamment des roulettes disposées entre les murs dressés latéralement et le sol mobile, les moyens de blocage quant à eux pouvant être, par exemple, des vérins situés en périmétrie du sol mobile et venant en contact avec lesdits murs latéraux dressés verrouillant ainsi le sol mobile à une certaine profondeur. [0014] De plus, le renvoi de câble est préférentiellement une poulie située au rebords de la piscine . En effet, ce renvoi de câble est apte à changer la direction du câble entre le sol mobile, en particulier à sa périmétrie, et la piscine, en particulier l'entraineur, où sont fixées respectivement les premières et secondes extrémités dudit câble. De cette manière, l'angle formé par le rebord de la piscine n'altère en rien l'efficacité de l'entraineur. [0015] Les éléments techniques cités dans la présente description sont des éléments techniques dont l'entretien est particulièrement aisé ce qui permet ainsi de se dispenser de tout local technique à proximité. [0016] De plus, le volume réduit dudit dispositif de fond mobile permet d'une part de le mettre en oeuvre sur toute nouvelle piscine mais aussi sur des piscines déjà existantes sans nécessiter de modification de l'espace extérieur. [0017] En outre, la multiplication de moyens de tractions permettant de limiter l'effort apporté par le moteur permet également de répondre au problème environnemental lié à l'énergie. En effet, la puissance nécessaire pour créer un effort de traction est telle que l'utilisation de moteurs basse tension est possible, d'où la possibilité également d'utiliser une source d'énergie solaire BREVE DESCRIPTION DES FIGURES [0018] D'autres caractéristiques, détails et avantages de l'invention ressortiront à la lecture de la description qui suit, en référence aux figures annexées, qui illustrent . -la figure 1 montre un schéma en coupe d'un dispositif de fond mobile d'une piscine selon un mode particulier de réalisation; -la figure 2 montre un schéma d'un dispositif de fond mobile d'une piscine selon ce même mode particulier de 30 réalisation, en vue de dessus.

Leur description ne sera pas systématiquement 35 répétée d'un mode de réalisation à l'autre. TECHNICAL FIELD OF THE INVENTION [0001] The technical field of the invention is that of buildings or similar constructions intended for a particular use such as swimming pools or wading pools, and more particularly to a mobile bottom device of such type. construction. STATE OF THE PRIOR ART [0002] The problem of moving bottoms of swimming pools, wading pools or similar constructions already knows several devices, in particular that of the establishment of a means of lift of a pool or paddling pool bottom such as lifting means by cables or articulated arms located at a lower level to said bottom of the pool and able on the one hand, to support it, and secondly, to translate vertically. As such, it is known the patent application EP1174569 A1 which describes a vertical mobile floor device for a pool or similar construction. More particularly, this system describes a device comprising a mobile floor capable of being driven vertically comprising flotation means, a means for lifting said ground along the side walls, a means of stabilizing said ground, said lifting means being characterized in that it comprises a chain hoisting system, motorized and arranged laterally to the pool and assisted by lifting arms able to secure the movement of said mobile floor of the pool. [0004] disadvantages, high, other cables, not including their length, Such devices have in particular on the one hand, to require a maintenance cost part, in the case of a solution using not allow uniform operation due cable returns, their elongation and finally this large device requires high power engines and the presence of a large technical room nearby. DESCRIPTION OF THE INVENTION [0005] The device described below aims to overcome the drawbacks of the state of the art and in particular to simply and reliably produce a mobile pool or wading pool bottom equipped with a movable bottom device. improved. [0006] For this purpose, the object of the invention is a movable bottom device of a swimming pool comprising a fixed base and erected lateral walls, this device comprising: a mobile ground; at least one means of pulling upwardly of said mobile floor capable of creating a force of which a principal component is directed upwards and comprising a trainer and a cable; characterized in that said traction means comprise at most one cable return, by cable. It is understood as being a reference 20 any movement transmission member changing the direction thereof, in particular the cable. It is also understood that a trainer is a means of driving the cable, motorized or not. [0009] According to one particular characteristic, said cable has a first end attached to said movable floor and a second end attached to the pool. Advantageously said coach is attached to the pool and includes the second end constituting a cable pool. [0010] The coach, located on the surface of the pool, is able to wind and unwind the cable. As a result, the provision of multiple means of traction in perimetry of the pool allows, by the action of the trainers, to create a traction force on the cables and thus to mount the movable ground. Conversely, when the trainers reverse this traction force, it allows the descent of the moving ground. According to another characteristic, said attachment of the first end is located in perimetry of said movable floor. This makes it possible, on the one hand, to improve the stability of the moving ground during its movement and, on the other hand, to improve the efficiency of the action of the trainer. During a change of state of the moving ground and more precisely from a static state to a raised state, the coach, whether motorized or manual, must overcome an inertial effort at startup due to the moving ground weight. In order to limit this effort, the mobile ground comprises flotation means making it possible to partially relieve the effect of the weight of said moving ground and thus to overcome this starting inertia. Indeed, in the case of a motorized trainer, it allows to use, for example, low voltage motors compatible with a solar energy supply, and in the case of a manual trainer, to relieve the effort to provide, for example in the rotation of a crank. Advantageously, the mobile pool bottom device comprises means for guiding and / or blocking said mobile floor vis-à-vis said side walls, these guide and / or locking means being located in perimetry of said movable floor. . This, on the one hand, for the purpose of allowing to guide the rise and the descent and the mobile ground and, on the other hand, to ensure the blocking at the chosen depth. These guiding means may in particular be rollers arranged between the walls erected laterally and the movable floor, the locking means for their part being, for example, cylinders located in perimetry of the moving ground and coming into contact with said erected side walls. thus locking the moving ground to a certain depth. In addition, the cable return is preferably a pulley located at the edge of the pool. Indeed, this cable return is able to change the direction of the cable between the mobile floor, particularly at its perimetry, and the pool, in particular the trainer, where are fixed respectively the first and second ends of said cable. In this way, the angle formed by the edge of the pool does not affect the effectiveness of the trainer. The technical elements mentioned in this description are technical elements whose maintenance is particularly easy, which allows to dispense with any nearby technical room. In addition, the reduced volume of said mobile bottom device allows on the one hand to implement it on any new pool but also on existing pools without requiring modification of the outdoor space. In addition, the multiplication of traction means to limit the effort provided by the engine also addresses the environmental problem related to energy. Indeed, the power required to create a traction force is such that the use of low voltage motors is possible, hence the possibility also to use a solar energy source. BRIEF DESCRIPTION OF THE FIGURES [0018] Other characteristics, details and advantages of the invention will become apparent on reading the description which follows, with reference to the appended figures, which illustrate. FIG 1 shows a sectional diagram of a movable bottom device of a swimming pool according to a particular embodiment; FIG. 2 shows a diagram of a mobile bottom device of a swimming pool according to this same particular embodiment, with a view from above. For clarity, identical or similar elements of the different embodiments will be identified by identical reference signs throughout the figures. Their description will not be systematically repeated from one embodiment to another.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION [0020] La figure 1 montre un schéma d'un dispositif de fond mobile d'une piscine selon un mode de réalisation de l'invention. En effet, la piscine représentée comporte un fond fixe (2) et des murs dressés latéralement (3). Ainsi le dispositif de fond mobile (1) comporte un sol mobile (4) apte à être guidé verticalement en montée comme en descente par l'intermédiaire de moyens de guidage, ces moyens de guidage étant des roulettes (11) fixées latéralement au sol mobile (4), c'est-à-dire entre le sol mobile (4) et les murs latéraux dressés (3). [0021] Le sol mobile (4) est maintenu par l'intermédiaire de moyens de traction (5). Chaque moyen de traction (5) comprend un entraineur (6) et un câble (7) dont une première extrémité (9) est fixée au sol mobile (4) et dont une seconde extrémité (10) est fixée à la piscine. L'entraineur étant fixe en surface de la piscine, c'est donc par son intermédiaire que la seconde extrémité y est fixée constituant ainsi une réserve de câble (7). [0022] Dans ce cas particulier les entraineurs (6) sont des moteurs à basse tension, ceci afin de pouvoir utiliser l'énergie solaire répondant ainsi à la problématique environnementale. [0023] De ce fait, la rotation du moteur basse 25 tension fait varier la longueur de câble et fait ainsi varier la profondeur du sol mobile (4). [0024] Une poulie (8), unique renvoi de câble présent dans ce moyen de traction est située en bordure supérieure de la piscine, ceci afin que le câble soit le plus verticale 30 possible au niveau de sa première extrémité et, par conséquent, d'améliorer l'efficacité du moteur. [0025] La figure 2 montre un schéma d'un dispositif de fond mobile d'une piscine selon ce même mode particulier de réalisation, en vue de dessus pour une piscine de section 35 rectangulaire et dont le sol mobile (4) est adapté à cette forme. [0026] De nombreuses modifications peuvent être apportées au mode particulier de réalisation décrit précédemment sans sortir du cadre de l'invention. [0027] Ainsi, les formes générales du sol mobile ou de la piscine peuvent être différents. En effet, la forme de la piscine est libre et permet ainsi au dispositif tel que décrit de pouvoir s'adapter sur toute forme de piscine, nouvelle ou déjà existante. [0028] En outre, il est possible d'envisager un entraineur apte à entrainer plusieurs câbles. Cet entraineur pouvant être motorisé ou bien, dans une autre configuration, être manuel, voir les deux ce qui permet l'adaptation d'un dispositif manuel de sécurité en cas d'avarie électrique. [0029] Enfin, on précise que dans le vocable « câble », on doit comprendre autant un fil métallique ou autre matériaux, qu'une structure comprenant une succession de maillons ou combinaisons d'éléments similaires. Il s'agit à priori d'un moyen relativement fin présentant deux extrémités libres opposées. DETAILED DESCRIPTION OF AN EMBODIMENT [0020] FIG. 1 shows a diagram of a moving bottom device of a swimming pool according to one embodiment of the invention. Indeed, the pool shown has a fixed bottom (2) and walls laterally erected (3). Thus the mobile bottom device (1) comprises a movable floor (4) able to be guided vertically upwards or downwards by means of guide means, these guide means being rollers (11) laterally fixed to the movable floor. (4), that is to say between the mobile floor (4) and the erected side walls (3). The movable floor (4) is maintained by means of traction means (5). Each traction means (5) comprises a driver (6) and a cable (7), a first end (9) is fixed to the movable floor (4) and a second end (10) is fixed to the pool. The trainer being fixed on the surface of the pool, it is through it that the second end is fixed thereby constituting a cable pool (7). In this particular case the trainers (6) are low voltage motors, in order to be able to use solar energy thus responding to the environmental problem. [0023] As a result, the rotation of the low voltage motor varies the length of the cable and thus makes the depth of the moving ground (4) vary. A pulley (8), single cable return present in this traction means is located at the upper edge of the pool, so that the cable is as vertical as possible 30 at its first end and, therefore, to improve the efficiency of the engine. [0025] FIG. 2 shows a diagram of a mobile bottom device of a swimming pool according to this same particular embodiment, seen from above for a pool of rectangular section and whose mobile floor (4) is adapted to this shape. Many modifications can be made to the particular embodiment described above without departing from the scope of the invention. Thus, the general shape of the mobile floor or the pool may be different. Indeed, the shape of the pool is free and allows the device as described to adapt to any form of pool, new or existing. In addition, it is possible to consider a trainer capable of driving several cables. This trainer can be motorized or, in another configuration, be manual, see both which allows the adaptation of a manual safety device in case of electrical damage. Finally, it is specified that in the term "cable", one must understand as much a wire or other materials, a structure comprising a succession of links or combinations of similar elements. It is a priori a relatively fine means with two opposite free ends.
