Description

La présente invention concerne un dispositif de régulation du débit d'un skimmer dans un bassin, notamment d'une piscine, en vue de créer un effet de chute et une accélération du courant de surface.The present invention relates to a device for regulating the flow of a skimmer in a pool, in particular a swimming pool, with a view to creating a drop effect and an acceleration of the surface current.

On connaît des dispositifs permettant de créer un effet de chute dans un skimmer. Les skimmer sont des bouches de sortie d'eau qui débouchent sur le bassin et qui sont situées au niveau du fil de l'eau. Ces bouches sont reliées au circuit de traitement d'eau de la piscine de façon à retirer les corps flottants par aspiration d'une part et d'autre à faire passer l'eau prélevée et aspirée par une pompe à travers un dispositif de traitement d'eau, par exemple au sel ou au chlore.Devices are known for creating a falling effect in a skimmer. The skimmers are mouths of water outlet which open on the basin and which are located at the level of the wire of the water. These mouths are connected to the water treatment circuit of the pool so as to remove the floating bodies by suction on the one hand and other to pass the water drawn and sucked by a pump through a treatment device. water, for example salt or chlorine.

Ce traitement et cette mise en service est réalisée suivant une programmation établie par le responsable du bassin.This treatment and this commissioning is carried out according to a schedule established by the basin manager.

Pour les débris et autres corps étrangers comme le sable, pour nettoyer les parois du bassin, il est prévu un aspirateur qui circule au fond de l'eau.For debris and other foreign objects such as sand, to clean the walls of the basin, there is a vacuum cleaner that circulates at the bottom of the water.

Pour les débris en surface comme les feuilles, il est possible de réaliser un recueil manuel des feuilles au moyen d'une épuisette mais on comprend tout de suite le caractère fastidieux d'une telle opération.For debris on the surface such as leaves, it is possible to perform a manual collection of leaves by means of a landing net but it is immediately understand the tedious nature of such an operation.

Pour assurer un drainage des feuilles en surface d'un bassin, une solution consiste à créer un courant de surface à partir des skimmers.In order to ensure drainage of the leaves on the surface of a pond, one solution is to create a surface current from the skimmers.

C'est ainsi que le brevet américain US 6 453 483 décrit un dispositif venant se fixer à l'intérieur d'une bouche d'au moins un skimmer d'une piscine. Ce dispositif est fixe et obture partiellement l'ouverture dudit skimmer par un volet. Ce volet est monté pivotant sur une base fixée au skimmer en façade, laissant un passage en partie supérieure, situé sous le fil de l'eau si bien qu'il se produit un effet de chute avec un fort écoulement en surface et non sur la hauteur d'eau de l'ouverture du skimmer. Ce brevet couvre plus particulièrement un agencement avec un volet articulé. On aspire donc avec la pompe un volume d'eau constant lié à la capacité de la pompe mais un volume uniquement prélevé en surface si bien qu'il se crée un courant favorable en surface qui a tendance à conduire les matières flottantes vers ledit skimmer.This is how the US patent US 6,453,483 describes a device that is fixed inside a mouth of at least one skimmer of a pool. This device is fixed and partly closes the opening of said skimmer by a shutter. This flap is mounted pivoting on a base attached to the skimmer on the front, leaving a passage in the upper part, located under the wire of the water so that there is a falling effect with a strong flow on the surface and not on the water level of the skimmer opening. This patent more particularly covers an arrangement with an articulated flap. The pump therefore draws a constant volume of water related to the capacity of the pump but a volume only taken from the surface so that a favorable surface current is created which tends to conduct the floating materials towards said skimmer.

On constate que le problème du dispositif de ce document de l'art antérieur c'est qu'il est fixe par rapport au skimmer et ne suit pas le fil de l'eau qui voit son niveau varier régulièrement.It is noted that the problem of the device of this document of the prior art is that it is fixed with respect to the skimmer and does not follow the thread of the water which sees its level vary regularly.

Aussi dès que le niveau d'eau baisse dans le bassin, que ce niveau se trouve en-dessous des volets pivotants, il n'y a plus d'eau qui s'écoule dans le skimmer et la pompe peut se détériorer.As soon as the water level in the pool drops below the pivoting flaps, there is no more water flowing into the skimmer and the pump can deteriorate.

On connaît également le brevet français FR 2 736 344 qui décrit un agencement avec une façade qui est mobile en translation verticale car elle est montée dans des rails rapportés de façon fixe sur le skimmer. Des flotteurs assurent le maintien de la façade au droit du fil de l'eau.French patent is also known FR 2,736,344 which describes an arrangement with a facade which is movable in vertical translation because it is mounted in rails fixedly attached to the skimmer. Floats ensure the maintenance of the facade to the right of the water line.

Dès que l'aspiration de la pompe s'exerce, l'eau aspirée chute à travers une ouverture située sous le fil de l'eau de façon à obtenir un effet de chute et une aspiration du volume d'eau lié à la capacité de la pompe mais aspiré uniquement en surface si bien qu'il se crée un courant d'aspiration en surface.As soon as the suction of the pump is exerted, the sucked water falls through an opening located under the wire of the water so as to obtain a falling effect and an aspiration of the volume of water related to the capacity of the the pump but sucked only on the surface so that a suction current is created on the surface.

Il n'y a aucun volet de régulation, si bien que l'effet de chute est limité, déterminé et constant. De plus, les salissures ne sont pas retenues dans le skimmer lorsque la pompe est à l'arrêt.There is no regulation flap, so the fall effect is limited, determined and constant. In addition, dirt is not retained in the skimmer when the pump is stopped.

On peut encore citer le brevet US 4 608 167 qui décrit un agencement de skimmer intégrant des glissières dans lesquelles est un volet inférieur flottant muni de dents aptes à coopérer avec une crémaillère ménagée dans lesdites glissières. Des butées évitent que ledit volet inférieur ne se dégage des glissières.We can also mention the patent US 4,608,167 which describes a skimmer arrangement incorporating slides in which is a floating lower flap provided with teeth adapted to cooperate with a rack formed in said slides. Stoppers prevent said lower flap from being disengaged from the slides.

Un volet supérieur flottant est articulé et peut basculer dans une plage limitée par un ressort de rappel.A floating upper flap is hinged and can tilt in a limited range by a return spring.

On comprend que dès qu'il y a le moindre effort vers l'arrière le volet va se bloquer en hauteur, ne permettant pas un ajustement en hauteur.It is understood that as soon as there is the slightest effort to the rear the flap will lock in height, not allowing a height adjustment.

De plus ce dispositif utilise des glissières avec tous les inconvénients liés à un dispositif mécanique à savoir la présence de feuille et autres corps étrangers qui peuvent venir se bloquer dans la crémaillère.In addition this device uses slides with all the disadvantages associated with a mechanical device namely the presence of sheet and other foreign bodies that can come hang in the rack.

De plus, un tel agencement nécessite de modifier le skimmer présent ou de prévoir un skimmer spécifique dès l'origine.In addition, such an arrangement requires modifying the present skimmer or providing a specific skimmer from the beginning.

Un tel système purement mécanique n'est pas satisfaisant.Such a purely mechanical system is not satisfactory.

Le but de la présente invention est de pallier les problèmes de l'art antérieur, en provoquant un courant d'aspiration de surface d'un bassin à partir d'un skimmer, mais sans nécessiter de modification du skimmer, en étant adaptable au fil de l'eau, en permettant une réalisation industrielle, en autorisant une mise en place instantanée et très simple ne nécessitant aucune adaptation du skimmer, en permettant un retrait aussi instantané et aussi simple, en créant un courant d'aspiration optimisé et en retenant les impuretés à l'intérieur du skimmer en fonctionnement normal sans aspiration.The object of the present invention is to overcome the problems of the prior art, by causing a surface suction of a basin from a skimmer, but without requiring modification of the skimmer, being adaptable to the wire of water, allowing an industrial realization, by authorizing an instantaneous installation and very simple not requiring any adaptation of the skimmer, by allowing a withdrawal as instantaneous and as simple, by creating an optimized aspiration current and retaining the impurities inside the skimmer in normal operation without suction.

Sur la figure 1, on a représenté le dispositif selon la présente invention adapté pour coopérer avec un skimmer d'un bassin.On the figure 1 the device according to the present invention is shown adapted to cooperate with a skimmer of a basin.

Ce dispositif comprend une base 10, d'une largeur supérieure à celle du skimmer 12 sur lequel elle doit être disposée.This device comprises a base 10, of a width greater than that of the skimmer 12 on which it must be arranged.

Le skimmer 12 a une fenêtre 14 qui est l'ouverture proprement dite et un cadre 16 périphérique qui vient se plaquer sur la paroi du bassin, notamment pour assurer l'étanchéité lors de la présence d'un liner. Ce cadre 16 pénètre dans l'ouverture en créant un ressaut 18 périphérique intérieur.The skimmer 12 has a window 14 which is the actual opening and a peripheral frame 16 which is pressed against the wall of the basin, in particular to ensure tightness during the presence of a liner. This frame 16 enters the opening by creating an inner peripheral projection 18.

La hauteur de cette base 10 est sensiblement celle du skimmer 12 avec lequel elle doit coopérer.The height of this base 10 is substantially that of the skimmer 12 with which it must cooperate.

La base 10 comprend une face avant AV et une face arrière AR. La face arrière est celle qui est destinée à se plaquer contre le skimmer et la face avant regarde le bassin.The base 10 comprises a front face AV and a rear face AR. The back side is the one that is intended to be pressed against the skimmer and the front faces the pelvis.

Cette base 10 comprend un volet 20, articulé par rapport à la base et au-dessus de ladite base, autour d'une charnière 22. Ce volet 20 est articulé pour pivoter par rapport à la base, de façon préférentielle vers une face de ladite base, en l'occurrence vers la face arrière AR de ladite base comme il sera expliqué ci-après.This base 10 comprises a flap 20, articulated with respect to the base and above said base, around a hinge 22. This flap 20 is articulated to pivot relative to the base, preferably towards a face of said base, in this case to the rear face AR of said base as will be explained below.

La largeur du volet 10 est inférieure à la largeur de la fenêtre 14 du skimmer 12, de façon à pouvoir pivoter en son sein.The width of the flap 10 is smaller than the width of the window 14 of the skimmer 12, so as to be pivotable therein.

Le volet 20 comporte également des moyens 24 de fixation amovible du dispositif selon l'invention par rapport au skimmer. Ces moyens 24 de fixation amovible prennent la forme de languettes 26 souples, élastiques, aptes à se bloquer derrière le ressaut 18 périphérique intérieur du skimmer par simple encliquetage. La largeur entre les extrémités des languettes est au moins égale à celle de la fenêtre 14.The flap 20 also comprises means 24 for removably fixing the device according to the invention with respect to the skimmer. These removable fixing means 24 take the form of resilient tongues 26, resilient, able to lock behind the protrusion 18 inner device of the skimmer by simple snapping. The width between the ends of the tongues is at least equal to that of the window 14.

La base 10 est constituée d'un matériau ayant une flottabilité négative et le volet 20 est constitué d'un matériau ayant une flottabilité positive.The base 10 is made of a material having a negative buoyancy and the flap 20 is made of a material having a positive buoyancy.

Le dispositif complet est flottant c'est-à-dire que la flottabilité du volet assure la reprise de la flottabilité négative de la base.The complete device is floating, that is to say that the buoyancy of the flap ensures the recovery of the negative buoyancy of the base.

C'est ainsi que la base 10 est suspendue au volet 20 flottant.Thus the base 10 is suspended from the flap 20 floating.

Le bord supérieur du volet 12 affleure ainsi le fil de l'eau, de préférence légèrement en-dessous, de l'ordre de quelques millimètres, la base 10 constituant alors une quille articulée.The upper edge of the flap 12 is thus flush with the wire of the water, preferably slightly below, of the order of a few millimeters, the base 10 then constituting an articulated keel.

Ainsi que représenté sur la figure 2, le dispositif est présenté devant la fenêtre du skimmer et les moyens 24 de fixation amovible, solidaires du volet 20 sont introduits dans la fenêtre 14 du skimmer 12. Dans le mode de réalisation représenté, les languettes 26, souples, s'accrochent derrière le ressaut 18 du cadre 16 du skimmer 12. Elles permettent un mouvement en translation verticale, en hauteur et limitent tout mouvement de translation en horizontal et donc tout dégagement intempestif du dispositif.As shown on the figure 2 , the device is presented in front of the window of the skimmer and the means 24 for detachable attachment, integral with the shutter 20 are introduced into the window 14 of the skimmer 12. In the embodiment shown, the tabs 26, flexible, hang behind the jump 18 of the frame 16 of the skimmer 12. They allow movement in vertical translation, height and limit any translational motion in horizontal and therefore any inadvertent release of the device.

C'est ce qui est représenté sur les figures 3 et 4.This is what is represented on the Figures 3 and 4 .

Le dispositif est donc retenu par les moyens 24 de fixation amovible du volet. La base 10 est suspendue au volet 20 et le dessus du volet affleure la surface par son bord supérieur.The device is thus retained by the means 24 for removably fastening the shutter. The base 10 is suspended from the flap 20 and the top of the flap is flush with the surface by its upper edge.

Dans cette position, comme montré sur la figure 5, suivant la hauteur d'eau dans le bassin, le dispositif peut suivre le fil de l'eau car il n'est aucunement immobilisé en translation, par aucune glissière, il est totalement flottant.In this position, as shown on the figure 5 , depending on the water level in the basin, the device can follow the wire of the water because it is not immobilized in translation, by any slide, it is totally floating.

Aucun moyen de guidage en translation ne s'avère nécessaire car les languettes assurent le maintien du dispositif devant la fenêtre.No guide means in translation is necessary because the tabs maintain the device in front of the window.

Les moyens 24 de fixation amovible assurent la retenue du dispositif devant la fenêtre du skimmer sans aucune pression la base restant libre, uniquement maintenue devant la fenêtre par sa flottabilité négative.The means 24 for removable attachment ensure the retention of the device in front of the window of the skimmer without any pressure remaining free base, maintained solely in front of the window by its negative buoyancy.

Le bord inférieur de la base 10 est situé en-dessous du bord inférieur de la fenêtre et donc du cadre.The lower edge of the base 10 is located below the lower edge of the window and therefore the frame.

Comme montré sur la figure 5, le dispositif laisse libre la partie supérieure de la fenêtre et en fonctionnement statique, les salissures flottantes qui passent par-dessus le volet du dispositif sont ensuite retenues dans le skimmer par ledit volet, évitant tout retour vers le bassin.As shown on the figure 5 , the device leaves free the upper part of the window and in static operation, the floating dirt that passes over the shutter of the device are then retained in the skimmer by said flap, avoiding any return to the basin.

L'eau du bassin se trouve devant le dispositif, derrière le dispositif, le volet est légèrement incliné vers l'arrière puisque son point de fixation amovible est en arrière du cadre de la fenêtre, cadre qui est situé dans le plan de la paroi du bassin.The basin water is in front of the device, behind the device, the flap is slightly inclined backwards since its removable attachment point is behind the window frame, which frame is located in the plane of the wall of the window. basin.

Le bassin est équipé d'une pompe, d'un circuit de recirculation et de traitement de l'eau dudit bassin, ceci de façon bien connue. La pompe aspire l'eau au fond du skimmer qui est équipé d'un filtre de façon à retenir les corps étrangers passés par la fenêtre du skimmer et dirige cette eau pompée vers les moyens de traitement non représentés, avant un retour au bassin.The basin is equipped with a pump, a recirculation circuit and water treatment of said basin, this in a well known manner. The pump draws water from the bottom of the skimmer which is equipped with a filter so as to retain the foreign bodies passed through the window of the skimmer and directs the pumped water to the not shown treatment means, before returning to the pool.

Le dispositif réagit de la façon suivante à la mise en service de la pompe.The device responds as follows to the commissioning of the pump.

En figure 6A, lorsque la pompe est en service, elle aspire de l'eau au fond du skimmer et crée un courant. Le courant ainsi créé est suffisant pour plaquer la base 10 contre le cadre et plus le skimmer se vide et plus la pression d'eau du bassin s'exerce sur la base et la plaque contre le cadre.In Figure 6A when the pump is in operation, it draws water from the bottom of the skimmer and creates a current. The current thus created is sufficient to press the base 10 against the frame and the skimmer empties more and the water pressure of the pelvis is exerted on the base and the plate against the frame.

La base se trouve ainsi immobilisée par la pression de l'eau contre le cadre du skimmer, par simple placage.The base is thus immobilized by the pressure of the water against the frame of the skimmer, by simple plating.

Dès lors, simultanément et proportionnellement à la diminution de la hauteur d'eau dans le skimmer, derrière la base, le volet bascule vers l'arrière pour prendre un position proche de l'horizontale car il ne peut plus se maintenir vertical par flottaison, n'ayant plus d'eau, voir figure 6B.Therefore, simultaneously and proportionally to the decrease in the water level in the skimmer, behind the base, the flap tilts backwards to take a position close to the horizontal because it can no longer maintain vertical floating, no more water, see Figure 6B .

L'eau du bassin passe par-dessus le volet car le fil de l'eau est au niveau du bord supérieur du volet lorsqu'il est en position relevée.The pond water passes over the flap because the water line is at the upper edge of the flap when in the raised position.

On obtient donc un effet de chute d'eau derrière la base d'un volume d'eau important prélevé en surface, ce qui conduit à générer un courant de surface puissant, voir figure 6C. Les feuilles et autres impuretés flottantes sont aspirées et conduites vers le filtre panier du skimmer qui les retient.We thus obtain a waterfall effect behind the base of a large volume of water taken from the surface, which leads to generating a powerful surface current, see Figure 6C . The leaves and other floating impurities are sucked up and lead to the basket filter of the skimmer which holds them.

Dès lors que la pompe est mise à l'arrêt, l'eau remplit de nouveau le skimmer et le volet 20 se remet à flotter, le volet bloque les salissures à l'intérieur du skimmer, la base se décolle du cadre du skimmer contre lequel elle n'est plus plaquée et le dispositif est retenu par les moyens 24 de fixation amovible à savoir les languettes, prêt pour une nouvelle séquence, voir figure 6D.As soon as the pump is stopped, the water refills the skimmer and the flap 20 starts to float, the flap blocks the dirt inside the skimmer, the base comes off the skimmer frame against which it is no longer plated and the device is retained by the means 24 of removable attachment namely the tabs, ready for a new sequence, see Figure 6D .

Si l'utilisateur souhaite retirer le dispositif il lui suffit d'exercer un effort de traction sur le dispositif, sensiblement perpendiculairement à la paroi du bassin et au plan de la fenêtre pour retirer ledit dispositif, les languettes se pliant pour permettre ce retrait.If the user wishes to remove the device it is sufficient to exert a tensile force on the device, substantially perpendicular to the wall of the basin and the plane of the window to remove said device, the tabs folding to allow this withdrawal.

Avantageusement, la base peut être réalisée en un matériau d'une densité très légèrement supérieure à celle de l'eau mais susceptible de se remplir d'eau pour qu'il n'y ait pas de flottabilité engendrée par de l'air emprisonné.Advantageously, the base may be made of a material with a density slightly greater than that of water but capable of being filled with water so that there is no buoyancy caused by trapped air.

Quant au volet, il est avantageusement réalisé dans le même matériau dont les espaces vides sont comblés par un matériau à coefficient de flottabilité positive comme de la mousse à alvéoles fermées.As for the flap, it is advantageously made of the same material whose voids are filled by a positive buoyancy coefficient material such as closed cell foam.

Le matériau pour réaliser les différents éléments qui le constitue peut être celui qui est utilisé pour la fabrication des lames de rideaux de piscine dont on sait qu'il est parfaitement adapté tant en résistance mécanique, qu'en résistance aux rayons ultraviolets et aux agents de traitement comme le chlorure de sodium ou le chlore.The material for making the various elements that constitute it can be the one used for the manufacture of pool curtain blades which are known to be perfectly suited both for mechanical strength and resistance to ultraviolet light and treatment agents such as sodium chloride or chlorine.

Dans le mode de réalisation particulier retenu, la charnière 22 est avantageusement continue sur toute la largeur du volet sous forme d'une lamelle souple en matière polymère. Cette lamelle est environ de la largeur du volet et d'une hauteur de quelques millimètres, venue de fabrication avec la base et coopérant avec le bord inférieur du volet.In the particular embodiment chosen, the hinge 22 is advantageously continuous over the entire width of the flap in the form of a flexible strip of polymeric material. This slat is about the width of the shutter and a height of a few millimeters, coming from manufacture with the base and cooperating with the lower edge of the shutter.

Cet agencement ne fait appel ainsi à aucun élément métallique susceptible de se corroder.This arrangement thus does not use any metal element likely to corrode.

Selon une variante de réalisation des moyens 24 de fixation amovible à languettes, il est prévu une butée 24-1 qui peut être auto collante et destinée à être fixée dans le skimmer. Cette butée, par exemple en élastomère, est collée sur la face supérieure, horizontale, intérieure du cadre du skimmer.According to an alternative embodiment of the means 24 for releasably fixing tabs, there is provided a stop 24-1 which can be self-adhesive and intended to be fixed in the skimmer. This abutment, for example made of elastomer, is bonded to the upper, horizontal, inner face of the skimmer frame.

Ainsi, lorsque le dispositif selon l'invention est mis en place, il suffit de glisser le volet 20 derrière la butée 24-1, en enfonçant l'ensemble dans l'eau sur la hauteur de ladite butée soit quelques millimètres.Thus, when the device according to the invention is put in place, simply slide the flap 20 behind the abutment 24-1, by pressing the assembly into the water on the height of said abutment is a few millimeters.

Ensuite, en fonctionnement normal, sans aspiration, l'ensemble est retenu, dès que la base 10 est plaquée, le volet peut basculer vers l'arrière, la butée étant inutile, comme précédemment. Ceci implique une gestion rigoureuse de la hauteur d'eau, ce qui est généralement le cas, des détecteurs adaptés permettant une régulation précise.Then, in normal operation, without suction, the assembly is retained, as soon as the base 10 is plated, the flap can swing backwards, the stop being useless, as before. This implies rigorous management of the water level, which is generally the case, adapted detectors allowing precise regulation.

Cette butée montre un moyen simplifié de réalisation des moyens 24 de fixation amovible laissant encore plus de liberté puisqu'il n'y a plus contact, celui des languettes, déjà minime, étant supprimé.This abutment shows a simplified means for producing the means 24 for removable attachment leaving even more freedom since there is no contact, that of the tabs, already minimal, being removed.
