Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention se rapporte au domaine de la sécurité d'un bassin de piscine. Elle concerne plus précisément les dispositifs permettant de faciliter le recouvrement ou le découvrement d'un bassin de piscine au moyen d'une couverture souple avantageusement équipée de barres longitudinales afin de garantir la tenue d'une telle couverture au-dessus du bassin de piscine.The invention relates to the field of safety of a swimming pool. It relates more specifically to devices for facilitating the recovery or uncovering of a swimming pool by means of a flexible cover advantageously equipped with longitudinal bars to ensure the holding of such a cover over the pool.

De telles couvertures à barres peuvent présenter une masse très importante et être difficiles à manipuler pour procéder à leur déroulement ou enroulement au-dessus du bassin. Par ailleurs, de manière à éviter le frottement de ces couvertures sur les margelles périphériques du bassin, il est préférable d'enrouler/dérouler sur elles-mêmes de telles couvertures. Ces couvertures restent donc immobiles à la surface des margelles, mais viennent s'enrouler sur elles-mêmes autour d'une barre d'enroulement entraînée en rotation par des moyens annexes généralement motorisés.Such bar covers may have a very large mass and be difficult to manipulate to proceed with their unwinding or winding over the basin. Moreover, in order to avoid the friction of these covers on the peripheral edges of the basin, it is preferable to wrap / unroll on themselves such covers. These covers therefore remain motionless on the surface of the curbs, but are wrapped around themselves around a winding bar driven in rotation by generally motorized auxiliary means.

Ainsi, l'invention vise plus particulièrement un dispositif motorisé permettant de faciliter ces opérations d'enroulement/déroulement de la couverture sur elle-même. De tels dispositifs comportent ainsi des moyens motorisés aptes à générer le mouvement de rotation de la barre d'enroulement et ainsi l'enroulement sur elle-même de la couverture.Thus, the invention is more particularly a motorized device for facilitating these winding operations / unfolding of the cover on itself. Such devices thus comprise motorized means able to generate the rotational movement of the winding bar and thus the winding on itself of the cover.

ART ANTERIEURPRIOR ART

De façon générale, et tel que décrit dans le brevet FR-2 846 690 , il est connu d'utiliser un dispositif d'aide à l'enroulement dans lequel un bras de liaison permet de suivre l'augmentation du diamètre d'enroulement de la couverture autour d'une barre d'enroulement au fur et à mesure que l'on découvre la surface libre du bassin de piscine.In general, and as described in the patent FR-2,846,690 it is known to use a winding aid device in which a link arm makes it possible to follow the increase in the winding diameter of the cover around a winding bar as and when we discover the free surface of the swimming pool.

Cependant, dans ce dispositif, le bras de liaison est disposé à l'extérieur du volume d'encombrement défini par un châssis rigide muni de roulettes au contact du sol. Le déport réalisé entre l'axe motorisé et l'axe de rotation du bras de liaison par rapport au châssis rigide génère alors un couple de torsion supplémentaire entraînant en rotation le châssis rigide et empêchant celui-ci de se déplacer rectilignement par rapport à la surface du bassin. A cet effet, il est prévu une canne permettant de corriger cette déviation et de forcer le chariot à rester orienté parallèlement par rapport au bord généralement rectiligne du bassin.However, in this device, the connecting arm is disposed outside the volume of space defined by a rigid frame provided with wheels in contact with the ground. The offset carried out between the motorized axis and the axis of rotation of the link arm relative to the rigid frame then generates an additional torsion torque rotating the rigid frame and preventing it from moving rectilinearly with respect to the surface of the basin. For this purpose, there is provided a cane for correcting this deflection and forcing the carriage to remain oriented parallel to the generally rectilinear edge of the basin.

Ainsi, un tel dispositif nécessite de la part de l'utilisateur une vigilance toute particulière pour éviter la déviation du rouleau lors de son enroulement/déroulement. De plus, lorsque le rouleau présente un diamètre d'enroulement important, cette correction de la déviation peut demander un effort physique très important de la part de l'utilisateur. Un tel dispositif n'est donc pas satisfaisant et ne permet pas un enroulement/déroulement automatique sans l'assistance physique d'une personne.Thus, such a device requires from the user a particular vigilance to avoid the deviation of the roll during its winding / unwinding. In addition, when the roller has a large winding diameter, this correction of the deviation may require a very significant physical effort on the part of the user. Such a device is therefore not satisfactory and does not allow automatic winding / unwinding without the physical assistance of a person.

Par ailleurs, on connaît également des dispositifs tels que décrits dans le document FR-2 885 378 dans lequel, le dispositif d'aide à l'enroulement présente une structure allongée avec à l'une de ses extrémités un axe motorisé et à l'autre de ses extrémités des éléments roulants aptes à permettre le roulement sans frottement du châssis rigide allongé par rapport aux margelles périphériques du bassin.Moreover, devices as described in the document are also known. FR-2,885,378 wherein, the winding aid has an elongate structure with at one of its ends a motorized axis and at the other end of its rolling elements able to allow frictionless rolling of the elongated rigid frame by relative to the peripheral margins of the basin.

Ainsi, lors de l'enroulement de la couverture autour de la barre d'enroulement, le diamètre du rouleau augmente et le dispositif suit cette augmentation de diamètre en élevant par rapport au sol l'extrémité libre présentant l'axe motorisé.Thus, during the winding of the cover around the winding bar, the roll diameter increases and the device follows this increase in diameter by raising the free end with the motorized axis relative to the ground.

Cependant, lors de l'enroulement d'une couverture comportant une pluralité de barres transversales, le diamètre d'enroulement d'un tel rouleau n'est pas constant et peut présenter des variations importantes engendrant, lors du passage d'une bosse à un creux, une accélération du mouvement de rotation du rouleau. L'extrémité libre en contact avec le sol et comportant des éléments roulants est alors soulevée, puis le rouleau ralentit brutalement lorsqu'il se trouve dans sa position de diamètre la plus faible, et l'extrémité libre du dispositif vient alors frapper violemment les margelles du bassin. Ces chocs sont alors transmis à l'ensemble des éléments constituant le dispositif et peuvent les détériorer rapidement, engendrant un disfonctionnement, voire une panne du dispositif. Ainsi, une telle conception du dispositif ne permet pas de garantir un fonctionnement avec une durée de vie importante.However, when winding a cover comprising a plurality of transverse bars, the winding diameter of such a roll is not constant and may have significant variations generating, during the passage of a bump to a hollow, an acceleration of the rotational movement of the roll. The free end in contact with the ground and having rolling elements is then raised, then the roller slows down suddenly when it is in its position of the smallest diameter, and the free end of the device then comes to hit the curbs violently. of the basin. These shocks are then transmitted to all the elements constituting the device and can deteriorate quickly, causing a malfunction or failure of the device. Thus, such a design of the device does not guarantee operation with a long service life.

Par ailleurs, ce phénomène peut également endommager les margelles du bassin de piscine en générant des fissures ou tout simplement des marques disgracieuses au niveau de leur surface supérieure visible.Moreover, this phenomenon can also damage the edges of the pool basin by generating cracks or simply unsightly marks at their visible upper surface.

Enfin, un tel dispositif peut se révéler dangereux pour l'utilisateur qui peut être blessé lors du déplacement saccadé du dispositif causé par une variation brutale du diamètre d'enroulement du rouleau formé par la couverture.Finally, such a device can be dangerous for the user who can be injured during the jerky movement of the device caused by a sudden change in the winding diameter of the roll formed by the cover.

Le but de l'invention est donc de réaliser un dispositif d'aide à l'enroulement/déroulement d'une couverture au-dessus d'un bassin qui soit totalement autonome, présentant une grande fiabilité de fonctionnement dans le temps et qui ne présente aucun risque de dégradation pour les margelles du bassin ou danger pour l'utilisateur.The object of the invention is therefore to provide a device for assisting the winding / unfolding of a blanket over a basin which is completely independent, having a high reliability of operation over time and which does not present no risk of degradation for the basin edges or danger for the user.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention concerne donc un dispositif d'aide à l'enroulement/déroulement d'une couverture souple au-dessus d'un bassin de piscine. Un tel dispositif comporte :

  • des moyens motorisés électriques aptes à entraîner en rotation un axe équipé d'un premier organe d'accouplement, ce premier organe d'accouplement étant apte à coopérer avec un second organe d'accouplement de forme complémentaire assujetti à une barre d'enroulement équipant la couverture souple au niveau d'au moins une de ses lisières ;
  • une source d'énergie électrique autonome pour alimenter les moyens motorisés ;
  • un élément de commande électrique de l'alimentation des moyens motorisés.
The invention therefore relates to a device for assisting the winding / unfolding of a flexible cover over a swimming pool. Such a device comprises:
  • electric motorized means adapted to drive in rotation an axis equipped with a first coupling member, said first coupling member being adapted to cooperate with a second coupling member of complementary shape secured to a winding bar fitted to the flexible cover at at least one of its edges;
  • an autonomous source of electrical energy for powering the motorized means;
  • an electrical control element of the power supply of the motorized means.

Selon l'invention, le dispositif se caractérise en ce qu'il comporte :

  • une enveloppe présentant une forme de révolution à l'intérieure de laquelle les moyens motorisé et la source d'énergie électrique autonome sont agencés, une telle enveloppe comportant :
    • ■ une surface externe de roulement destinée à rouler sur le sol le long du bassin de piscine ;
    • ■ deux ouvertures parallèles agencées de part et d'autre de la surface externe de roulement ;
  • un ensemble mobile motorisé permettant de positionner l'axe dans une zone proximale de l'enveloppe et parallèlement par rapport à un axe de révolution de l'enveloppe, l'ensemble mobile motorisé comportant :
    • ▪ les moyens motorisés électriques ;
    • ▪ la source d'énergie électrique autonome ;
    • ▪ deux platines parallèles agencées respectivement chacune au niveau d'une ouverture de l'enveloppe ;
    • ▪ des moyens de solidarisations formant entretoise et permettant de maintenir à égale distance les deux platines parallèles ;
  • des moyens de guidage permettant d'assujettir en liaison pivot l'ensemble mobile motorisé par rapport à l'enveloppe.
According to the invention, the device is characterized in that it comprises:
  • an envelope having a form of revolution within which the motorized means and the source of autonomous electrical energy are arranged, such an envelope comprising:
    • ■ an external running surface intended to roll on the ground along the swimming pool;
    • Two parallel openings arranged on either side of the outer bearing surface;
  • a motorized moving assembly for positioning the axis in a zone proximal to the envelope and parallel to an axis of revolution of the envelope, the motorized moving assembly comprising:
    • ▪ motorized electric means;
    • ▪ the source of autonomous electrical energy;
    • ▪ two parallel plates respectively arranged at an opening of the envelope;
    • ▪ securing means forming a spacer and for maintaining the two parallel plates at equal distance;
  • guiding means for securing in pivot connection the moving motorized assembly relative to the casing.

Autrement dit, l'ensemble mobile motorisé peut librement pivoter à l'intérieur de l'enveloppe. Un tel agencement est notamment utile pour s'adapter à l'augmentation du diamètre du rouleau formé par la couverture souple lors de son enroulement. Inversement, un tel agencement permet également de s'adapter à la diminution de diamètre du rouleau formé par la couverture souple lors de son déroulement.In other words, the motorized moving assembly can freely rotate inside the envelope. Such an arrangement is particularly useful for adapting to the increase in the diameter of the roll formed by the flexible cover during its winding. Conversely, such an arrangement also makes it possible to adapt to the decrease in diameter of the roll formed by the flexible cover during its unwinding.

Un tel dispositif d'aide à l'enroulement permet également de suivre les variations localisées du diamètre d'enroulement du rouleau formé par la couverture souple lorsque notamment des barres viennent déformer la cylindricité du rouleau. De telles barres forment alors un balourd pouvant faire varier brusquement le niveau en hauteur de l'axe de rotation de la barre d'enroulement équipant la couverture souple. Dans ce cas, un tel dispositif d'aide à l'enroulement subit simplement une accélération rectiligne de son mouvement de roulement sur le sol.Such a winding aid device also makes it possible to follow the localized variations in the winding diameter of the roll formed by the flexible cover when, in particular, bars deform the cylindricity of the roll. Such bars then form an unbalance that can vary abruptly the level in height of the axis of rotation of the winding bar equipping the flexible cover. In this case, such a winding aid device simply undergoes a rectilinear acceleration of its rolling motion on the ground.

Avantageusement, le centre de gravité de l'ensemble mobile motorisé peut être décalé par rapport à un axe de la liaison pivot entre l'ensemble mobile motorisé et l'enveloppe de façon à former un balourd, et permettre, lorsque l'ensemble mobile est au repos, de positionner automatiquement l'axe au plus près du sol.Advantageously, the center of gravity of the motorized moving assembly can be offset relative to an axis of the pivot connection between the motorized moving assembly and the casing. so as to form an unbalance, and allow, when the moving assembly is at rest, to automatically position the axis closer to the ground.

En d'autres termes, lorsqu'un tel dispositif n'est pas utilisé, le balourd de l'ensemble mobile motorisé permet de positionner l'axe en regard du sol pour faciliter notamment l'accouplement entre le premier organe d'accouplement solidaire de l'axe et le second organe d'accouplement solidaire de la barre d'enroulement. Par ailleurs, un tel agencement permet également de transmettre à la couverture souple un effort vertical vers le bas de façon à automatiquement réaliser une mise sous tension de la couverture souple lors de son enroulement. Une telle mise sous tension permet alors d'éviter la formation de plis à la surface du rouleau formé par la couverture souple.In other words, when such a device is not used, the unbalance of the motorized moving assembly makes it possible to position the axis facing the ground in order, in particular, to facilitate the coupling between the first integral coupling member of the axis and the second coupling member secured to the winding bar. Moreover, such an arrangement also makes it possible to transmit a vertical force downwardly to the flexible cover so as to automatically tension the flexible cover when it is wound up. Such a power up then makes it possible to prevent the formation of folds on the surface of the roll formed by the flexible cover.

En pratique, les moyens motorisés électriques et la source d'énergie autonome peuvent être solidarisés à l'une au moins des deux platines.In practice, the motorized electric means and the autonomous energy source can be secured to at least one of the two plates.

Ainsi, l'ensemble mobile motorisé peut librement pivoter à l'intérieur de l'enveloppe sans que les moyens motorisés électriques et la source d'énergie autonome puissent venir en contact avec l'enveloppe.Thus, the motorized movable assembly can freely rotate inside the casing without the motorized electric means and the autonomous energy source being able to come into contact with the casing.

Selon un mode de réalisation particulier, l'une au moins des deux platines peut comporter un orifice agencé dans la zone proximale de l'enveloppe, l'axe passant au travers de l'orifice.According to a particular embodiment, at least one of the two plates may comprise an orifice arranged in the proximal zone of the envelope, the axis passing through the orifice.

Autrement dit, lorsque les platines présentent une forme pleine sensiblement circulaire, c'est-à-dire en obstruant sensiblement toute la surface des ouvertures parallèles de l'enveloppe, l'axe passe au travers d'un orifice ménagé dans l'une des platines.In other words, when the plates have a solid shape substantially circular, that is to say by substantially obstructing the entire surface of the parallel openings of the casing, the axis passes through an orifice in one of the turntables.

Cependant, dans d'autres modes de réalisation, les platines peuvent présenter une forme ouverte, dans ce cas l'axe motorisé peut émerger directement au niveau des ouvertures parallèles de l'enveloppe.However, in other embodiments, the plates may have an open shape, in this case the motorized axis can emerge directly at the parallel openings of the envelope.

Avantageusement, la surface externe de roulement peut comporter des moyens d'adhérence aptes à éviter le glissement de la surface externe sur le sol lors de son fonctionnement.Advantageously, the outer rolling surface may comprise adhesion means able to prevent the sliding of the outer surface on the ground during its operation.

Dans ce cas, des moyens d'adhérence permettent de garantir le mouvement de rotation du dispositif par rapport au sol. De tels moyens d'adhérence peuvent notamment se présenter sous la forme d'une bande formée dans un matériau tel que du caoutchouc vulcanisé. Ils peuvent également se présenter sous la forme de plusieurs éléments disjoints régulièrement répartis à la périphérie de la surface externe de roulement de l'enveloppe. De tels éléments disjoints peuvent se présenter sous la forme de picots ou d'anneaux notamment.In this case, adhesion means make it possible to guarantee the rotational movement of the device relative to the ground. Such adhesion means may in particular be in the form of a strip formed in a material such as vulcanized rubber. They may also be in the form of several disjoint elements regularly distributed around the periphery of the outer rolling surface of the envelope. Such disjoint elements may be in the form of pins or rings in particular.

En pratique, le dispositif peut comporter une cellule photovoltaïque connectée électriquement pour recharger la source d'énergie électrique autonome.In practice, the device may comprise a photovoltaic cell electrically connected to recharge the source of autonomous electrical energy.

En d'autres termes, la source d'énergie électrique autonome du dispositif peut être rechargée automatiquement grâce à l'énergie solaire. Une telle cellule photovoltaïque peut notamment être positionnée sur l'enveloppe ou encore sur l'une au moins des deux platines parallèles du dispositif.In other words, the autonomous power source of the device can be recharged automatically by solar energy. Such a photovoltaic cell may in particular be positioned on the envelope or on at least one of the two parallel plates of the device.

Selon un mode de réalisation particulier, le dispositif peut comporter une poignée solidarisée à l'une au moins des deux platines parallèles.According to a particular embodiment, the device may comprise a handle secured to at least one of the two parallel plates.

Une telle poignée peut se présenter sous différentes formes tel un élément rigide ou une bande de textile souple comportant deux extrémités solidarisées respectivement chacune à l'une des platines parallèle.Such a handle may be in various forms such as a rigid element or a flexible textile strip having two ends each secured respectively to one of the parallel plates.

Avantageusement, les moyens de guidage comportent au moins deux éléments roulants assujettis en liaison pivot avec respectivement chacune des deux platines, les éléments roulants coopérant selon un mouvement de roulement sans glissement avec une surface interne de l'enveloppe.Advantageously, the guiding means comprise at least two rolling elements secured in pivot connection with respectively each of the two plates, the rolling elements cooperating in a rolling motion without sliding with an inner surface of the casing.

Autrement dit, chacune des platines comporte des agencements permettant de guider en rotation au moins deux éléments roulants. De tels agencements peuvent notamment se présenter sous la forme de logements, de paliers, de coussinets ou encore de roulements à aiguilles ou à billes notamment.In other words, each of the plates comprises arrangements for rotating guide at least two rolling elements. Such arrangements may in particular be in the form of housings, bearings, bearings or even needle bearings or ball bearings in particular.

En pratique, chacun des éléments roulants peut comporter une paire de roulettes solidarisée à un axe. Dans ce cas, les extrémités de l'axe coopèrent avec les deux platines parallèles. Les roulettes sont dans ce cas assujetties en liaison encastrement avec l'axe.In practice, each of the rolling elements may comprise a pair of wheels secured to an axis. In this case, the ends of the axis cooperate with the two parallel plates. The casters are in this case secured in connection with the axis.

Bien entendu, selon d'autres variantes, les roulettes peuvent être montées en liaison pivot sur l'axe qui est alors fixe par rapport aux platines. Dans ce cas, les agencements assurant la liaison pivot sont positionnés au niveau de chaque roulette, et non au niveau des extrémités de l'axe.Of course, according to other variants, the wheels can be mounted in pivot connection on the axis which is then fixed relative to the plates. In this case, the arrangements providing the pivot connection are positioned at each wheel, and not at the ends of the axis.

Selon un mode de réalisation particulier, le dispositif peut comporter des éléments antifrictions agencés au niveau des ouvertures parallèles de l'enveloppe, ces éléments antifrictions permettant de limiter le coefficient de frottement entre les platines et l'enveloppe.According to a particular embodiment, the device may comprise anti-friction elements arranged at the level of the parallel openings of the envelope, these anti-friction elements making it possible to limit the coefficient of friction between the plates and the envelope.

De cette manière, les éléments antifriction permettent à l'ensemble mobile motorisé de pivoter librement à l'intérieur de l'enveloppe, tout en évitant le mouvement de translation relatif selon l'axe de rotation de cette liaison pivot. De tels éléments antifriction peuvent notamment se présenter sous la forme de patins en polytétrafluoroéthylène (PTFE), mais également sous la forme de butées ou de douilles à billes ou à aiguilles.In this way, the anti-friction elements allow the motorized moving assembly to pivot freely inside the casing, while avoiding the relative translation movement along the axis of rotation of this pivot connection. Such anti-friction elements may in particular be in the form of polytetrafluoroethylene (PTFE) pads, but also in the form of abutments or ball or needle sockets.

Selon un autre mode de réalisation, l'élément antifriction peut être directement obtenu par l'utilisation de matériaux spécifiques pour former les platines et/ou l'enveloppe du dispositif.According to another embodiment, the anti-friction element can be directly obtained by the use of specific materials to form the plates and / or the envelope of the device.

Par ailleurs, chacune des ouvertures parallèles de l'enveloppe peut avantageusement comporter au moins un agencement coopérant avec une forme complémentaire de la platine en regard et étant destiné à former un labyrinthe anti-poussière.Furthermore, each of the parallel openings of the envelope may advantageously comprise at least one arrangement cooperating with a complementary shape of the facing platen and being intended to form a dust labyrinth.

Ainsi, les platines et l'enveloppe peuvent présenter des agencements évitant à la poussière du milieu extérieur de pénétrer à l'intérieur de l'enveloppe. De tels labyrinthes anti-poussière sont généralement réalisés en faisant pénétrer une portion fixe formant une nervure circulaire à l'intérieur d'une rainure mobile également circulaire. Un épaulement pénétrant à l'intérieur d'un alésage peut également permettre de former ce type de labyrinthe anti-poussière.Thus, the plates and the envelope may have arrangements preventing the dust of the external environment from penetrating inside the envelope. Such dust labyrinths are generally made by penetrating a fixed portion forming a circular rib within a movable groove also circular. A penetrating shoulder within a bore may also make it possible to form this type of dust labyrinth.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Comme déjà évoqué, l'invention concerne un dispositif permettant de procéder à l'enroulement/déroulement d'une bâche de piscine, notamment à barres, au-dessus d'un bassin de piscine.As already mentioned, the invention relates to a device for winding / unwinding a pool cover, including bars, above a pool pool.

Tel que représenté à la figure 1, le dispositif 1 coopère avec une barre d'enroulement 7 équipant au moins l'une des lisières d'une couverture souple 2. Lors de son utilisation, le dispositif 1 roule alors sur le sol à proximité des margelles délimitant le contour du bassin de piscine 3. La couverture souple 2 s'enroule alors sur elle-même autour de la barre d'enroulement 7. As shown in figure 1 , the device 1 cooperates with a winding bar 7 equipping at least one of the edges of a flexible cover 2. In use, the device 1 then rolls on the ground near the margins defining the contour of the basin of 3. The flexible cover 2 then wraps around itself around the winding bar 7.

Pour ce faire, l'utilisateur utilise un élément de commande électrique 15, représenté ici tel une télécommande filaire, et permettant de piloter des moyens motorisés du dispositif 1. Un tel élément de commande électrique 15 peut, selon d'autre variantes, également se présenter sous la forme d'une télécommande à radiofréquences, c'est-à-dire sans fil le reliant aux moyens motorisés, ou encore un élément portatif tel un téléphone portable ou une tablette électronique connectée par une liaison sans fil avec les moyens motorisés du dispositif 1 en utilisant des protocoles de communication sans fil tels que les protocoles Wifi ou Bluetooth.To do this, the user uses an electric control element 15, shown here as a wired remote control, and for controlling motorized means of the device 1. Such an electrical control element 15 may, in other variants, also be present in the form of a radio frequency remote control, that is to say wirelessly connecting it to the motorized means, or a portable element such as a mobile phone or an electronic tablet connected by a wireless link with the motorized means of the device 1 using wireless communication protocols such as Wifi or Bluetooth protocols.

Tel que représenté à la figure 2, le dispositif comporte une enveloppe 20 présentant une forme de révolution cylindrique à l'intérieur de laquelle les moyens motorisés sont positionnés. Une telle enveloppe comporte notamment une surface externe de roulement 21 permettant au dispositif 1 de rouler sur le sol le long du bassin de piscine.As shown in figure 2 , the device comprises an envelope 20 having a cylindrical revolution shape within which the motorized means are positioned. Such an envelope includes an outer rolling surface 21 allowing the device 1 to roll on the ground along the pool.

Un tel dispositif 1 comporte également deux platines parallèles 31 et 32 agencées respectivement chacune au niveau d'une ouverture circulaire de l'enveloppe 20. Such a device 1 also comprises two parallel plates 31 and 32 respectively arranged at a circular opening of the envelope 20.

Par ailleurs, les moyens motorisés électriques, non représentés ici, permettent d'entrainer en rotation un axe 6 émergeant de la platine 31 au niveau d'un orifice 34. Un tel orifice 34 est agencé dans une zone proximale de l'enveloppe 20, c'est-à-dire en étant décalé radialement par rapport à l'axe de rotation 24 de l'enveloppe 20 lors de sa rotation sur le sol.Moreover, the motorized electric means, not shown here, allow to drive in rotation an axis 6 emerging from the plate 31 at an orifice 34. Such an orifice 34 is arranged in a proximal zone of the envelope 20, that is to say being shifted radially relative to the axis of rotation 24 of the casing 20 during its rotation on the ground.

Tel que représenté à la figure 3, un tel dispositif 1 peut comporter également une poignée 4, ici représentée avec ses deux extrémités solidarisées avec les deux platines parallèles 31 et 32. De plus, une cellule photovoltaïque 26 est représentée au niveau de la platine 32, et permet d'alimenter en énergie électrique une source d'énergie électrique autonome positionnée à l'intérieur de l'enveloppe 20. As shown in figure 3 , such a device 1 may also comprise a handle 4, here represented with its two ends secured to the two parallel plates 31 and 32. In addition, a photovoltaic cell 26 is shown at the level of the plate 32, and allows to supply power. electrical energy an autonomous source of electrical energy positioned inside the casing 20.

Tel que représentés, des moyens d'adhérence 25 peuvent équiper la surface externe de roulement 21 de l'enveloppe 20. De tels moyens d'adhérence 25 se présentent dans ce cas sous la forme d'anneaux en matériaux caoutchouteux et augmentent ainsi le coefficient de frottement de la surface externe 21 de l'enveloppe 20 qui peut notamment être formée dans un alliage métallique tel qu'un alliage d'aluminium.As shown, adhesion means 25 can equip the outer rolling surface 21 of the envelope 20. Such adhesion means 25 are in this case in the form of rings of rubbery material and thus increase the coefficient of friction of the outer surface 21 of the envelope 20 which may in particular be formed in a metal alloy such as an aluminum alloy.

Par ailleurs, la platine 32 peut également comporter un support permettant la fixation de l'élément de commande électrique 15. Furthermore, the plate 32 may also include a support for fixing the electric control element 15.

Tel que représenté à la figure 4, le dispositif comporte un ensemble mobile motorisé 30 permettant notamment de positionner l'axe 6 dans une zone proximale de l'enveloppe 20. Un tel ensemble mobile motorisé 30 comporte notamment les moyens motorisés électriques 12, une source d'énergie électrique autonome 9, les deux platines parallèles 31 et 32 agencées respectivement chacune à niveau d'une ouverture 22, 23 de l'enveloppe 20, et des moyens de solidarisation 33 formant entretoise et permettant de maintenir à égale distance les deux platines parallèles 31, 32. As shown in figure 4 the device comprises a motorized movable assembly 30 making it possible in particular to position the axis 6 in a proximal zone of the envelope 20. Such a motorized moving assembly 30 comprises, in particular, the electric motorized means 12, an autonomous electrical energy source 9, the two parallel plates 31 and 32 each respectively arranged at an opening 22, 23 of the casing 20, and securing means 33 forming a spacer and for maintaining at an equal distance the two parallel plates 31, 32.

De tels moyens de solidarisation 33 peuvent notamment se présenter sous la forme de tubes taraudés, et de vis à tête fraisée pénétrant à l'intérieur des platines 31, 32. Bien entendu, de telles vis peuvent également être remplacées par des goujons et des écrous ou tout moyen de solidarisation réversible, tel que des goupilles, circlips ou analogues.Such fastening means 33 can in particular be in the form of threaded tubes, and countersunk screws penetrating inside the plates 31, 32. Of course, such screws can also be replaced by studs and nuts or any reversible securing means, such as pins, circlips or the like.

Un tel dispositif 1 comporte également des moyens de guidage 40 permettant d'assujettir en liaison pivot l'ensemble mobile motorisé 30 par rapport à l'enveloppe 20. De tels moyens de guidage 40 peuvent notamment comporter trois éléments roulants 41 assujettis en liaison pivot avec respectivement chacune des deux platines 31, 32. Ces éléments roulants 41 coopèrent par ailleurs selon un mouvement de roulement sans glissement avec une surface interne 26 de l'enveloppe 20. Such a device 1 also comprises guide means 40 for securing in pivot connection the motorized moving assembly 30 relative to the casing 20. Such guiding means 40 may in particular comprise three rolling elements 41 secured in pivot connection with each of the two plates 31, 32, respectively. These rolling elements 41 also cooperate in a non-slip rolling movement with an internal surface 26 of the envelope 20.

De tels éléments roulants 41 peuvent chacun comporter une paire de roulette 42 solidarisée à un axe 43. Such rolling elements 41 may each comprise a pair of wheels 42 secured to an axis 43.

De plus, un tel dispositif 1 comporte des éléments antifriction 5 positionnés au niveau des ouvertures parallèles 22, 23 de l'enveloppe 20 afin de limiter le coefficient de frottement entre les platines 31, 32 et l'enveloppe 20. De tels éléments antifriction 50 peuvent notamment se présenter sous la forme de patins de polytétrafluoroéthylène (PTFE), mais également sous la forme de douilles à aiguilles ou à billes.In addition, such a device 1 comprises anti-friction elements 5 positioned at the level of the parallel openings 22, 23 of the envelope 20 in order to limit the coefficient of friction between the plates 31, 32 and the envelope 20. Such antifriction elements 50 They may in particular be in the form of polytetrafluoroethylene (PTFE) pads, but also in the form of needle or ball bearings.

L'enveloppe 20 peut également comporter des agencements 51 formés par un alésage et positionnés au niveau des ouvertures 22, 23. De tels agencements 51 coopèrent alors avec une forme complémentaire, telle un épaulement, de la platine 31, 32 de façon à former un labyrinthe anti-poussière, protégeant ainsi les organes électriques et mécaniques contenus à l'intérieur de l'enveloppe de la poussière du milieu extérieur.The envelope 20 may also comprise arrangements 51 formed by a bore and positioned at the openings 22, 23. Such arrangements 51 then cooperate with a complementary shape, such as a shoulder, of the plate 31, 32 so as to form a labyrinth anti-dust, thus protecting the electrical and mechanical parts contained inside the envelope of the dust of the external environment.

Il ressort de ce qui précède qu'un dispositif conforme à l'invention présente de nombreux avantages, et notamment :

  • Il garantit l'enroulement et le déroulement d'une bâche souple de piscine, même pourvue de barres, sans générer d'à-coup ou de choc à la surface des margelles de la piscine ;
  • Il ne nécessite aucun effort de la part de l'utilisateur afin de maintenir le dispositif dans une orientation correspondant à la direction de déroulement ou d'enroulement de la bâche de piscine ;
  • Il est relativement compact et facile à stocker pendant notamment la période d'hivernage ;
  • Il permet de réaliser l'enroulement et le déroulement d'une bâche sans endommager celle-ci puisque celle-ci s'enroule sur elle-même sans frotter sur le sol ;
