Description

FOND MOBILE DE PISCINE A CREMAILLERE 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] Des tels dispositifs ont notamment les inconvénients, d'une part, de nécessiter un coût d'entretien élevé, d'autre part, dans le cas d'une solution utilisant des câbles, de ne pas permettre un fonctionnement uniforme dû notamment aux renvois des câbles, à leur allongement et à leur longueur, 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 [0004] 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 25 mobile de piscine ou pataugeoire muni d'un dispositif de fond mobile amélioré. [0005] A cet effet, l'invention a pour objet un 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 est dirigée vers le haut et comprenant un entraineur et une crémaillère ; [0006] Il est entendu qu'un entraineur est un moyen d'entraînement du sol mobil, motorisé ou non. [0007] Selon une caractéristique particulière ladite crémaillère présente une première extrémité fixée au sol de la piscine et une seconde extrémité fixée en haut la piscine. De façon avantageuse ledit entraineur est fixé au sol mobile. [0008] L'entraîneur, situé face à la crémaillère et fixé en périmètrie du sol mobile et solidaire de celui-ci est donc apte à circuler vers le haut ou vers le bas de la crémaillère. De ce fait, la disposition de multiples moyens de tractions en périmètrie de la piscine permet, par l'action des entraîneurs, de créer une force de traction sur les crémaillères et ainsi de monter le sol mobile. A l'inverse, lorsque les entraineurs inversent cet effort de traction, cela permet la descente du sol mobile. [0009] Selon une autre caractéristique, ladite crémaillère n'étant fixée qu'a chacune de ses extrémités, une pièce l'encercle afin de la garder en permanence en contact avec un moyen de traction. Cette pièce est fixe au fond mobile. [0010] 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 cet 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 moteurs basse tension 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. [0011] 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 10 mobile à une certaine profondeur. [0012] 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. [0013] De plus, le volume réduit dudit dispositif de fond mobile permet d'une part 15 de le mettre en oeuvre sur toute nouvelle piscine mais aussi sur des piscines déjà existantes sans nécessiter de modification de l'espace extérieur. [0014] 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 20 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. [0015] Avantageusement, les moyens de tractions sont équipés d'électro-freins puissants à manque de courant, permettant un blocage du dit fond mobile lorsqu'il se trouve dans une position d'usage intermédiaire sécurisant son utilisation.BACKGROUND 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 for a purpose of mobile background of such a 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. Such devices have the disadvantages, on the one hand, to require a high maintenance cost, on the other hand, in the case of a solution using cables, not to allow a uniform operation due in particular the return cables, their length and length, and finally, this bulky device requires high power engines and the presence of a large technical room nearby. DESCRIPTION OF THE INVENTION [0004] The device described hereinafter aims to remedy 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 bottom device. improved mobile. To this end, the invention relates to a movable bottom device of a swimming pool comprising a fixed base and erected side walls, the device comprising: - a movable floor; at least one pulling means upwardly of said movable floor capable of creating a force of which a principal component is directed upwards and comprising a trainer and a rack; It is understood that a trainer is a mobil drive means of the ground, motorized or not. According to a particular feature, said rack has a first end fixed to the ground of the pool and a second end fixed at the top of the pool. Advantageously, said trainer is fixed to the moving ground. The trainer, located in front of the rack and fixed in perimetry mobile ground and secured to it is able to flow up or down the rack. Therefore, the provision of multiple means of traction in perimeter of the pool allows, by the action of the coaches, to create a traction force on the racks and thus to mount the mobile floor. Conversely, when the trainers reverse this traction force, it allows the descent of the moving ground. According to another feature, said rack being fixed at each of its ends, a piece encircles it to keep it permanently in contact with a traction means. This piece is fixed to the moving bottom. 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 floor comprises flotation means for partially relieving the effect of the weight of said movable floor 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. 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 15 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 responds to 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 power source. Advantageously, the traction means are equipped with powerful electro-brakes with no current, allowing a locking said mobile bottom when it is in an intermediate use position securing its use.

25 BREVE DESCRIPTION DES FIGURES [0016] 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 réalisation, en vue de dessus. La figure 3 montre un schéma de la pièce encerclant la crémaillère vue de dessus [0017] Pour plus de clarté, les éléments identiques ou similaires des différents 10 modes de réalisation seront repérés par des signes de référence identiques sur l'ensemble des figures. Leur description ne sera pas systématiquement répétée d'un mode de réalisation à l'autre. DESCRIPTION DETAILLEE D'UN MODE DE REALISATION [0018] La figure 1 montre un schéma d'un dispositif de fond mobile d'une piscine 15 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), 20 c'est-à-dire entre le sol mobile (4) et les murs latéraux dressés (3). [0019] Le sol mobile (4) est maintenu par l'intermédiaire de moyens de traction (5). Chaque moyen de traction (5) comprend un entraineur (6) et une crémaillère (7) dont une première extrémité (9) est fixée au sol de la piscine (4) et dont une seconde extrémité (10) est fixée en haut de la piscine verticalement. L'entraîneur 25 étant fixe au fond mobile, c'est donc par son intermédiaire que le fond mobile monte ou descend. [0020] 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. Chaque entraineur (6), équipé d'un puissant 30 électro-frein à manque de courant se retrouve verrouillé sur la crémaillère lors de tout arrêt en position intermédiaire, sécurisant le fond mobile. [0021] 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 rectangulaire et dont le sol mobile (4) est adapté à cette forme. [0022] La figure 3 montre le détail de la pièce qui encercle la crémaillère (7) la 5 rendant solidaire du fond mobile (4) [0023] De nombreuses modifications peuvent être apportées au mode particulier de réalisation décrit précédemment sans sortir du cadre de l'invention. [0024] 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 10 que décrit de pouvoir s'adapter sur toute forme de piscine, nouvelle ou déjà existante. [0025] En outre, cet entraîneur 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. 15 [0026] Enfin, on précise que dans le vocable « crémaillère », on doit comprendre autant un profil 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. BRIEF DESCRIPTION OF THE FIGURES [0016] Other features, 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 mobile bottom device of a swimming pool according to a particular embodiment; Figure 2 shows a diagram of a movable bottom device of a pool according to this particular embodiment, in top view. FIG. 3 shows a diagram of the part encircling the rack seen from above. For the sake of clarity, the identical or similar elements of the various embodiments will be marked by identical reference signs throughout the figures. Their description will not be systematically repeated from one embodiment to another. DETAILED DESCRIPTION OF AN EMBODIMENT [0018] FIG. 1 shows a diagram of a moving bottom device of a swimming pool 15 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), i.e. between the movable floor (4) and the upstanding side walls (3). The mobile floor (4) is maintained by means of traction means (5). Each traction means (5) comprises a trainer (6) and a rack (7) whose first end (9) is fixed to the ground of the pool (4) and a second end (10) is fixed at the top of the swimming pool vertically. The driver 25 is fixed to the moving bottom, so it is through him that the moving bottom goes up or down. 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. Each trainer (6), equipped with a powerful electro-brake 30 lack of current is found locked on the rack during any stop in the intermediate position, securing the movable bottom. [0021] FIG. 2 shows a diagram of a mobile bottom device of a swimming pool according to this particular embodiment, in plan view for a pool of rectangular section and whose mobile floor (4) is adapted to this form. FIG. 3 shows the detail of the part which encircles the rack (7) making it integral with the mobile bottom (4). Many modifications can be made to the particular embodiment described above without departing from the scope of FIG. 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 10 to be able to adapt to any form of pool, new or existing. In addition, this trainer can be motorized or, in another configuration, be manual, see both allowing the adaptation of a manual safety device in case of electrical damage. Finally, it is specified that in the term "rack and pinion", one must understand as much a metal profile or other materials, as 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.
