Description

La présente invention a pour objet des couvertures motorisées de piscines ou autres bassins remplis d'un liquide.The present invention relates to motorized covers of swimming pools or other basins filled with a liquid.

Les couvertures de piscines sont de plus en plus répandues car elles permettent de protéger la piscine de manière à éviter la salissure de l'eau, l'évaporation et les pertes de calories.Swimming pool covers are more and more widespread because they protect the swimming pool so as to avoid water fouling, evaporation and loss of calories.

Cette couverture peut être réalisée au moyen de bâches tendues au-dessus de la piscine ou de corps flottants mais la mise en place et l'enlèvement de ceux-ci nécessitent des opérations longues et fastidieuses.This cover can be achieved by means of tarpaulins stretched over the pool or of floating bodies but the installation and removal of these require long and tedious operations.

On connaît également des couvertures de piscines motorisées du type volet roulant qui sont composées de lamelles articulées les unes aux autres qui flottent sur l'eau et qui s'enroulent sur un cylindre motorisé.There are also known covers for motorized swimming pools of the rolling shutter type which are made up of strips hinged to each other which float on the water and which are wound on a motorized cylinder.

Ces installations connues peuvent être équipées de différents systèmes d'entraînement. Dans un premier type d'installation, le dispositif d'entraînement constitué par un motoréducteur est installé dans une fosse qui est attenante au bassin, ce qui oblige à devoir traverser la paroi avec tous les problèmes d'étanchéité que cela engendre. En outre, il est nécessaire de construire ou de rapporter une fosse recevant la motorisation.These known installations can be equipped with different drive systems. In a first type of installation, the drive device constituted by a geared motor is installed in a pit which is adjacent to the basin, which means that you have to cross the wall with all the problems sealing that this generates. In addition, it is necessary to build or bring back a pit receiving the motorization.

Dans un deuxième type d'installation, le motoréducteur se trouve au-dessus du niveau du bassin, ce qui oblige à une surélévation du caisson et à une largeur de celui-ci plus importante que celle du bassin. En outre, le système d'entraînement, constitué généralement de pignons et de chaînes, se trouve alors disposé dans l'eau. Un tel dispositif d'enroulement est notamment décrit dans le brevet FR-A-2.450.927.In a second type of installation, the gearmotor is located above the level of the basin, which means that the box has to be raised and its width greater than that of the basin. In addition, the drive system, generally consisting of sprockets and chains, is then placed in the water. Such a winding device is described in particular in patent FR-A-2,450,927.

Dans un troisième mode de réalisation de ces installations, les systèmes de motorisation sont disposés en prolongement du cylindre qui est fixé sur les parois du bassin, ce qui oblige de nouveau à intervenir sur l'étanchéité de celui-ci.In a third embodiment of these installations, the motorization systems are arranged as an extension of the cylinder which is fixed to the walls of the basin, which again requires work to be carried out on the sealing thereof.

La couverture motorisée la plus performante à ce jour est à nos yeux celle décrite dans le brevet FR-A-2.508.525. Ce brevet décrit une couverture motorisée de piscine du type comportant des lamelles flottantes articulées entre elles qui s'enroulent sur un rouleau horizontal, entraîné en rotation par un groupe motoréducteur, l'invention se caractérisant par le positionnement du groupe motoréducteur par rapport au rouleau, ce dernier se trouvant en alignement avec le rouleau. Cependant, un tel dispositif pose encore de nombreux problèmes même s'il élimine de nombreux inconvénients des dispositifs antérieurs et permet notamment une mise en place rapide et peu onéreuse d'une couverture motorisée dans une piscine en absence de tout travail de maçonnerie. Cependant, cette couverture présente l'inconvénient d'être peu solide en raison de sa conception. En effet, le groupe motoréducteur, bien que disposé en alignement avec le rouleau, est solidarisé à ce dernier par un arbre de sortie, ce qui entraîne de ce fait une construction en porte-à-faux, l'ensemble ayant tendance à s'arc-bouter. En outre, la couverture, n'étant pas soutenue sur la totalité de sa longueur, a tendance à se déformer plus rapidement, ce qui oblige à la changer relativement souvent.The most efficient motorized cover to date is in our view that described in patent FR-A-2,508,525. This patent describes a motorized swimming pool cover of the type comprising floating lamellae hinged together which are wound on a horizontal roller, driven in rotation by a gearmotor group, the invention being characterized by the positioning of the gearmotor group relative to the roller, the latter being in alignment with the roller. However, such a device still poses many problems even if it eliminates many drawbacks of the prior devices and in particular allows a rapid and inexpensive installation of a motorized cover in a swimming pool in the absence of any masonry work. However, this blanket has the disadvantage of being weak because of its design. Indeed, the gearmotor, although arranged in alignment with the roller, is secured to the latter by an output shaft, which therefore results in a cantilever construction, the assembly tending to s' brace. In addition, the cover, not being supported over its entire length, tends to deform more quickly, which requires changing it relatively often.

Enfin, dans ce mode de réalisation, le groupe motoréducteur n'est pas protégé et son étanchéité est difficile à obtenir. En conséquence, ce dispositif n'est pas complètement satisfaisant.Finally, in this embodiment, the gearmotor group is not protected and its sealing is difficult to obtain. Consequently, this device is not completely satisfactory.

Le but de la présente invention est donc de proposer un dispositif d'entraînement du rouleau qui permette comme dans le brevet FR-A-2.508.525 de loger le rouleau et son dispositif d'entraînement dans la largeur de la piscine sans avoir à effectuer aucun travail de maçonnerie afin de permettre une mise en place rapide et peu onéreuse de la couverture motorisée tout en permettant d'obtenir une solidité extrême de l'ensemble ainsi qu'une bonne étanchéité et une faible usure du système d'entraînement et de la couverture.The object of the present invention is therefore to provide a roller drive device which, as in patent FR-A-2.508.525, can accommodate the roller and its drive device across the width of the pool without having to perform no masonry work to allow a quick and inexpensive installation of the motorized cover while allowing to obtain an extreme solidity of the assembly as well as a good seal and low wear of the drive system and the blanket.

L'invention concerne à cet effet une couverture motorisée de piscine et autres bassins analogues du type comportant des éléments flottants, tels que des lamelles, articulés entre eux et qui s'enroulent sur un rouleau horizontal de longueur inférieure à la largeur du bassin qui est immergé transversalement dans ladite piscine et qui est entraîné en rotation par un groupe motoréducteur, caractérisée en ce que le rouleau est maintenu immergé à l'intérieur du bassin au moyen d'un bâti qui affecte la forme d'un U dont l'âme est disposée au-dessus ou en affleurement du niveau de l'eau et supporte des moyens de recouvrement de la couverture automatique, tels qu'un caillebotis, et, dont les branches enchassent ledit rouleau et supportent sur leur face interne des paliers recevant les extrémités dudit rouleau.To this end, the invention relates to a motorized cover for swimming pools and other similar basins of the type comprising floating elements, such as lamellae, hinged together and which are wound on a horizontal roller of length less than the width of the basin which is transversely immersed in said pool and which is rotated by a geared motor group, characterized in that the roller is kept submerged inside the pool by means of a frame which takes the shape of a U whose soul is disposed above or flush with the water level and supports means for covering the automatic cover, such as a grating, and, the branches of which encase said roller and support on their internal face bearings receiving the ends of said roller.

Other characteristics and advantages of the invention will become apparent on reading the following description and the accompanying drawings, which description and drawings are given mainly by way of examples. In these drawings:
  • Figure 1 shows a sectional side view of a motorized blanket according to the invention, an attached partition panel for delimiting the flap in relation to the basin;

  • FIG. 6 represents a view in axial section of the drive device for the motorized cover.

Conformément aux figures 1 et 6, la couverture motorisée de piscine ou d'autres bassins analogues, objet de l'invention, comporte des éléments flottants, tels que des lamelles 26, articulés entre eux, qui s'enroulent sur un rouleau 1 horizontal. Ce rouleau cylindrique horizontal 1 est de longueur inférieure à la largeur du bassin 46 et est immergé transversalement dans ladite piscine. Ce rouleau 1 est entraîné en rotation par un groupe motoréducteur 14.In accordance with FIGS. 1 and 6, the motorized cover of a swimming pool or other similar basins, object of the invention, comprises floating elements, such as lamellae 26, hinged together, which are wound on a horizontal roller 1. This horizontal cylindrical roller 1 is of length less than the width of the basin 46 and is immersed transversely in said swimming pool. This roller 1 is driven in rotation by a geared motor group 14.

La particularité de la couverture motorisée, objet de l'invention, réside d'une part dans son bâti qui permet son positionnement dans la piscine, d'autre part dans la conception de l'ensemble rouleau/groupe motoréducteur.The peculiarity of the motorized cover, object of the invention, resides on the one hand in its frame which allows its positioning in the swimming pool, on the other hand in the design of the roller / gearmotor group assembly.

Le bâti est notamment représenté aux figures 4 et 5. Ce bâti qui affecte la forme générale d'un U est tel que l'âme creuse 4, 5, 10 est disposée au-dessus ou en affleurement du niveau de l'eau de manière à pouvoir supporter des moyens de recouvrement de la couverture automatique, tels qu'un caillebotis, et les branches 2, 3 dudit bâti enchassent ledit rouleau 1 et supportent sur leurs faces internes des paliers 6, 7 recevant les extrémités dudit rouleau. L'âme du bâti fait en outre saillie à chacune de ses extrémités des flasques 2 et 3 de manière à pouvoir venir en appui sur des supports 8 appropriés de telle sorte que le bâti est placé en suspension dans l'eau.The frame is in particular shown in Figures 4 and 5. This frame which has the general shape of a U is such that the hollow core 4, 5, 10 is arranged above or flush with the level water so as to be able to support means for covering the automatic cover, such as a grating, and the branches 2, 3 of said frame encase said roller 1 and support on their internal faces bearings 6, 7 receiving the ends of said roller. The core of the frame also projects at each of its ends from the flanges 2 and 3 so as to be able to bear on appropriate supports 8 so that the frame is placed in suspension in the water.

Ainsi, dans l'exemple représenté aux figures, les supports 8 de poutrelle sont fixés sur les parois du bassin au-dessus du niveau de l'eau par des moyens de fixation 44 appropriés, un joint étant intercalé entre le support 8 et la paroi latérale de la piscine. Ces supports 8 reçoivent les poutrelles 4 et 5 sur lesquelles sont soudés des profilés en U 9 qui reçoivent les traverses 10. Sur ces traverses sont fixés les flasques 2 et 3 par l'intermédiaire par exemple d'équerres 22 et 23 qui coopèrent avec des plots. Sur la face intérieure du flasque 2 est fixé le palier côté moteur 6 et sur le flasque 3 est fixé le palier côté libre 7. Ces paliers permettent la fixation du rouleau 1 à l'intérieur duquel est disposé le moteur réducteur 14. Le groupe motoréducteur 14 est donc constitué d'un corps dont l'une des extrémités comporte un arbre de sortie 47 fixe et dont l'autre extrémité comporte un arbre d'entraînement rotatif 48.Thus, in the example shown in the figures, the beam supports 8 are fixed to the walls of the basin above the water level by suitable fixing means 44, a seal being inserted between the support 8 and the wall side of the pool. These supports 8 receive the beams 4 and 5 on which are welded U-shaped sections 9 which receive the crosspieces 10. On these crosspieces are fixed the flanges 2 and 3 by means, for example, of brackets 22 and 23 which cooperate with studs. On the inner face of the flange 2 is fixed the bearing on the motor side 6 and on the flange 3 is fixed the bearing on the free side 7. These bearings allow the fixing of the roller 1 inside which the reduction motor is disposed 14. The geared motor group 14 therefore consists of a body, one end of which has a fixed output shaft 47 and the other end of which has a rotary drive shaft 48.

L'arbre d'entraînement rotatif 48 du groupe motoréducteur 14 est en prise avec un flasque intermédiaire 15 disposé à l'intérieur du rouleau 1 au moyen d'une clavette 16. Ce flasque 15 est quant à lui monté solidaire des parois périphériques internes du rouleau au moyen de vis. L'autre extrémité du groupe motoréducteur 14 constitué par l'arbre fixe 47 fait saillie hors de l'ensemble rouleau/groupe motoréducteur en traversant un flasque 18 disposé à l'extrémité de l'ensemble rouleau/groupe motoréducteur et monté solidaire des parois périphériques internes du rouleau au moyen là encore de vis. Des roulements 39 ménagés dans un logement annulaire dudit flasque 18 sont disposés à la périphérie de cet arbre fixe 47 de manière à faciliter la rotation de l'arbre 47 à l'intérieur de ladite plaque support 18. Cet arbre 47 vient reposer dans le palier 6 fixé sur la branche 2 du bâti support de rouleau et est immobilisé à l'intérieur de ce palier 6 au moyen d'une goupille traversante 19. L'autre extrémité de l'ensemble rouleau/groupe motoréducteur 14 est fermé par une plaque ou flasque 17 monté également solidaire des parois périphériques internes du rouleau 1 au moyen d'une goupille 35 qui traverse également un arbre ou axe 34 de manière à rendre solidaire cet axe de la plaque 17. Cet axe fait saillie hors de l'ensemble rouleau 1/groupe motoréducteur 14 et vient reposer dans le palier 7 fixé sur la branche 3 du bâti support de l'ensemble. Cet arbre 34 est monté libre à rotation à l'intérieur du palier 7, sa rotation étant facilitée par une bague 38. L'alimentation du groupe motoréducteur 14 se fait au moyen d'un câble d'alimentation 13.The rotary drive shaft 48 of the gearmotor group 14 is engaged with an intermediate flange 15 disposed inside the roller 1 by means of a key 16. This flange 15 is in turn mounted integral with the internal peripheral walls of the roller by means of screws. The other end of the gearmotor group 14 constituted by the fixed shaft 47 protrudes from the roller / gearmotor assembly by passing through a flange 18 disposed at the end of the roller / gearmotor assembly and mounted integral with the peripheral walls internal of the roller again by means of screws. Bearings 39 housed in a annular housing of said flange 18 are arranged at the periphery of this fixed shaft 47 so as to facilitate rotation of the shaft 47 inside said support plate 18. This shaft 47 comes to rest in the bearing 6 fixed on the branch 2 of the roller support frame and is immobilized inside this bearing 6 by means of a through pin 19. The other end of the roller / gearmotor group 14 assembly is closed by a plate or flange 17 also mounted integral with the internal peripheral walls of the roller 1 by means of a pin 35 which also passes through a shaft or axis 34 so as to make this axis of the plate 17 integral. This axis projects out of the assembly roller 1 / gearmotor group 14 and comes rest in the bearing 7 fixed on the branch 3 of the support frame of the assembly. This shaft 34 is mounted to rotate freely inside the bearing 7, its rotation being facilitated by a ring 38. The power supply to the geared motor group 14 is done by means of a power cable 13.

Les flasques 2 et 3 qui permettent de recevoir les paliers 6 et 7 peuvent en outre comporter des bras-support 25 qui permettent la mise en place du panneau de séparation 24, ce dernier séparant la couverture ou volet 26 du reste du bassin. Bien évidemment ce panneau de séparation 24 peut être remplacé par un mur en maçonnerie ou être totalement omis. Le bâti qui supporte le rouleau comporte dans sa partie supérieure des moyens de réception d'un caillebotis 27 qui recouvre l'ensemble de la couverture automatique lorsqu'elle est en position repliée. Ces moyens de réception sont notamment constitués par les poutrelles 4 et 5. Les dimensions et le positionnement du rouleau 1 sont tels que la couverture disparaît sous l'eau lorsqu'elle est entièrement enroulée et que l'extrémité libre de la couverture flotte dès qu'on commence à la dérouler. Grâce au mode de réalisation du bâti et du rouleau, il est possible de préfabriquer entièrement l'ensemble, puis d'avoir au moment de l'installation sur site, uniquement à fixer l'ensemble sur les parois latérales de la piscine en particulier par fixation des supports de poutrelles 8.The flanges 2 and 3 which make it possible to receive the bearings 6 and 7 may also include support arms 25 which allow the installation of the separation panel 24, the latter separating the cover or flap 26 from the rest of the basin. Obviously this partition panel 24 can be replaced by a masonry wall or be completely omitted. The frame which supports the roller comprises in its upper part means for receiving a grating 27 which covers the whole of the automatic cover when it is in the folded position. These receiving means are in particular constituted by the beams 4 and 5. The dimensions and the positioning of the roller 1 are such that the cover disappears underwater when it is fully wound up and that the free end of the cover floats as soon as 'we start to unroll it. Thanks to the embodiment of the frame and the roller, it is possible to completely prefabricate the assembly, then to have, at the time of installation on site, only to fix the assembly to the side walls of the pool, in particular by fixing beam supports 8.

Cette couverture motorisée comporte en outre un dispositif d'arrêt automatique en fin de course. Ce dispositif d'arrêt est constitué d'au moins deux cellules photo-électriques 11 et 12 qui sont fixées sur la poutrelle 4, ces cellules permettant de visualiser la position de la couverture 26 à l'aide de réflecteurs 20 et 21. Ces réflecteurs 20 et 21 sont disposés sur la face visible de la couverture 26 en des emplacements qui permettent de signaler le début et la fin de l'enroulement ou respectivement du déroulement de ladite couverture 26. Quant à la couverture 26 elle-même, elle peut être de tout type connu ou non.This motorized cover also includes an automatic end stop device. This stop device consists of at least two photoelectric cells 11 and 12 which are fixed to the beam 4, these cells making it possible to visualize the position of the cover 26 using reflectors 20 and 21. These reflectors 20 and 21 are arranged on the visible face of the cover 26 in locations which make it possible to signal the start and the end of the winding or respectively of the unwinding of said cover 26. As for the cover 26 itself, it can be of any known or unknown type.
