Description

La présente invention est relative à un panneau souple de fermeture qui, lorsqu'il n'est pas déployé en position active, peut être escamoté par enroulement, en général sur un tambour.The present invention relates to a flexible closing panel which, when not deployed in the active position, can be retracted by winding, generally on a drum.

L'invention s'applique en particulier, mais de manière non limitative, au recouvrement d'une piscine extérieure par un tel panneau souple, qui repose alors en surface de l'eau de la piscine lorsque celle-ci n'est pas utilisée.The invention applies in particular, but not limited to, the covering of an outdoor swimming pool with such a flexible panel, which then rests on the surface of the swimming pool water when the latter is not used.

Une autre application de l'invention vise la fermeture de balcons, notamment en période hivernale.Another application of the invention relates to the closing of balconies, in particular in winter.

Dans l'application préférée de l'invention à une couverture de piscine extérieure, on connaît déjà diverses techniques.In the preferred application of the invention to an outdoor swimming pool cover, various techniques are already known.

Une première technique consiste à utiliser une simple bâche qui est constituée par une feuille imperméable maintenue à la surface de l'eau par des flotteurs ou par des cordons prévus de place en place ; une autre technique, dérivée de la précédente, consiste à incorporer dans cette bâche une sorte de ballonnet par l'intermédiaire de bulles très minces qui assurent la flottabilité ; une autre technique encore consiste à utiliser des lamelles flottantes qui sont assemblées l'une à l'autre, à la manière d'un volet roulant.A first technique consists in using a simple tarpaulin which consists of an impermeable sheet held on the surface of the water by floats or by cords provided from place to place; another technique, derived from the previous one, consists in incorporating into this tarpaulin a sort of balloon by means of very thin bubbles which ensure buoyancy; still another technique consists in using floating strips which are assembled to one another, in the manner of a rolling shutter.

Aucune de ces techniques connues ne donne satisfaction. En effet, ces techniques soit sont onéreuses, soit donnent lieu à des manipulations délicates pour le déploiement et la rétraction du panneau, soit sont inefficaces quant au maintien de la température de l'eau en période froide.None of these known techniques is satisfactory. Indeed, these techniques are either expensive, or give rise to delicate manipulations for the deployment and retraction of the panel, or are ineffective in maintaining the water temperature in cold periods.

L'invention a pour but de remédier à ces inconvénients en proposant un panneau souple qui tout à la fois est peu onéreux, d'une manipulation aisée et surtout d'une efficacité notablement améliorée quant au maintien de la température de l'eau.The object of the invention is to remedy these drawbacks by proposing a flexible panel which is both inexpensive, easy to handle and, above all, significantly improved in efficiency as regards maintaining the temperature of the water.

A cet effet, le panneau souple selon l'invention, enroulable sur un support, est caractérisé en ce qu'il est constitué par au moins une plaque translucide comportant : une paroi extérieure continue s'étendant sur toute la largeur et sur toute la longueur de la plaque, ladite longueur de plaque se définissant comme celle de ses deux dimensions qui est parallèle à l'axe d'enroulement du support ; une paroi intérieure discontinue, parallèle à la paroi extérieure et s'étendant sur toute la longueur et, de manière discontinue, sur toute la largeur de la plaque ; et des parois longitudinales parallèles, s'étendant sur toute la longueur de la plaque, perpendiculairement aux parois extérieure et intérieure en les réunissant pour définir des groupes d'alvéoles longitudinaux successifs, deux groupes adjacents d'alvéoles successifs étant séparés par un espace résultant d'une interruption de la paroi intérieure et étant réunis seulement par la paroi extérieure qui, dans cette zone, constitue une partie de flexion pour l'enroulement de la plaque sur ledit support.To this end, the flexible panel according to the invention, which can be rolled up on a support, is characterized in that it is constituted by at least one translucent plate comprising: a continuous outer wall extending over the entire width and over the entire length of the plate, said length of plate being defined as that of its two dimensions which is parallel to the axis of winding of the support; a discontinuous inner wall, parallel to the outer wall and extending over the entire length and, discontinuously, over the entire width of the plate; and parallel longitudinal walls, extending over the entire length of the plate, perpendicular to the outer and inner walls, bringing them together to define groups of successive longitudinal cells, two adjacent groups of successive cells being separated by a space resulting from an interruption of the inner wall and being joined only by the outer wall which, in this zone, constitutes a bending part for the winding of the plate on said support.

Avantageusement, la paroi extérieure peut recevoir un revêtement d'interruption des rayons ultraviolets, et cette paroi définit de manière préférentielle la surface extérieure de l'enroulement sur le support.Advantageously, the outer wall can receive a coating for interrupting ultraviolet rays, and this wall preferably defines the outer surface of the winding on the support.

Les alvéoles sont de préférence emplis d'air, particularité qui permet le passage des rayons solaires et qui, en outre, dans l'application de l'invention aux couvertures de piscine, permet la flottabilité du panneau.The cells are preferably filled with air, a feature which allows the passage of sunlight and which, moreover, in the application of the invention to swimming pool covers, allows the buoyancy of the panel.

Avantageusement, la matière utilisée pour la plaque constitutive du panneau souple est du polycarbonate rigide.Advantageously, the material used for the constituent plate of the flexible panel is rigid polycarbonate.

Cette pièce peut être alors obtenue soit par extrusion à sa forme finale, soit par extrusion d'une plaque dont la paroi intérieure est continue, ladite extrusion étant alors suivie d'une opération d'enlèvement local de parties de la paroi intérieure pour définir respectivement les groupes d'alvéoles longitudinaux et les espaces longitudinaux.This part can then be obtained either by extrusion to its final shape, or by extrusion of a plate whose inner wall is continuous, said extrusion being then followed by a local removal operation of parts of the inner wall to define respectively the groups of longitudinal cells and the longitudinal spaces.

Dans la pratique, le panneau est de préférence constitué par une pluralité de plaques qui sont assemblées successivement suivant leur longueur, soit de manière mécanique, soit par un collage.In practice, the panel is preferably constituted by a plurality of plates which are assembled successively along their length, either mechanically or by bonding.

Avantageusement, le panneau comporte, par exemple en bout de la zone d'assemblage de deux plaques successives, des guides qui débordent au-delà des plaques pour coopérer par glissement sur l'ouvrage contre lequel le panneau est appliqué.Advantageously, the panel comprises, for example at the end of the assembly zone of two successive plates, guides which extend beyond the plates to cooperate by sliding on the structure against which the panel is applied.

En particulier, dans l'application préférentielle de l'invention aux couvertures de piscine, les alvéoles peuvent être bouchés à leurs extrémités pour éviter notamment la pénétration de l'eau, ce bouchage se faisant par exemple à l'aide d'un mastic au silicone.In particular, in the preferred application of the invention to swimming pool covers, the cells can be plugged at their ends to avoid in particular the penetration of water, this plugging being done for example using a putty at silicone.

Egalement dans cette application particulière, la plaque qui est la plus éloignée du tambour d'enroulement présente avantageusement une partie longitudinale qui est inclinée vers le haut pour former une sorte de spatule de ski ou de patin lors de la mise en place du panneau sur l'eau.Also in this particular application, the plate which is furthest from the winding drum advantageously has a longitudinal part which is inclined upwards to form a sort of ski or skid tip when the panel is placed on the 'water.

Dans une autre application de l'invention dans laquelle le panneau souple est destiné à constituer une fermeture de balcon, enroulable sur un tambour horizontal supérieur, la paroi extérieure continue dudit panneau définit préférentiellement la face extérieure de cette fermeture. Déployé, le panneau souple peut être soit vertical, soit incliné sur l'horizontale selon un angle qui, généralement, sera compris entre 30 et 90°. Avantageusement, le panneau souple sera alors guidé latéralement dans des glissières en U, qui assureront au surplus sa stabilité s'il y a du vent.In another application of the invention in which the flexible panel is intended to constitute a balcony closure, which can be rolled up on an upper horizontal drum, the continuous outer wall of said panel preferably defines the outer face of this closure. Deployed, the flexible panel can be either vertical or inclined to the horizontal at an angle which, generally, will be between 30 and 90 °. Advantageously, the flexible panel will be then guided laterally in U-shaped slides, which will also provide stability if there is wind.

On comprendra bien l'invention à la lecture du complément de description qui va suivre et en référence aux dessins annexés qui font partie de la description et dans lesquels :

The invention will be clearly understood on reading the additional description which follows and with reference to the appended drawings which form part of the description and in which:
  • Figure 1 is a schematic perspective view of a panel established according to a preferred embodiment of the invention in its application to an outdoor swimming pool cover;

On a schématiquement représenté sur la figure 1, en perspective, l'utilisation du panneau souple selon l'invention dans son application préférée à une couverture de piscine extérieure.Schematically shown in Figure 1, in perspective, the use of the flexible panel according to the invention in its preferred application to an outdoor swimming pool cover.

Le panneau 1 selon l'invention est constitué par une pluralité de plaques rectangulaires 2, cinq plaques dans l'exemple considéré, qui sont assemblées bout à bout suivant leur longueur.The panel 1 according to the invention consists of a plurality of rectangular plates 2, five plates in the example considered, which are assembled end to end according to their length.

Le panneau 1 est dimensionné pour pouvoir occuper sensiblement toute la surface de l'eau et il peut être enroulé sur un support du type tambour horizontal 3 prévu à une extrémité de la longueur de la piscine, à une hauteur appropriée. La longueur de chaque plaque 2 se définit donc comme celle de ses deux dimensions qui est parallèle à l'axe d'enroulement du tambour 3.The panel 1 is sized to be able to occupy substantially the entire surface of the water and it can be wound on a support of the horizontal drum type 3 provided at one end of the length of the pool, at an appropriate height. The length of each plate 2 is therefore defined as that of its two dimensions which is parallel to the winding axis of the drum 3.

Ce tambour 3 est monté sur des supports verticaux 4 et il est actionné par tous moyens appropriés, par exemple par un moteur ou plus simplement à la main, à l'aide d'une manivelle 5.This drum 3 is mounted on vertical supports 4 and it is actuated by any appropriate means, for example by a motor or more simply by hand, using a crank 5.

Des cordons 6 sont fixés à une extrémité sur le tambour 3 et à l'autre extrémité sur le bord longitudinal de la première plaque 2.Cords 6 are fixed at one end to the drum 3 and at the other end to the longitudinal edge of the first plate 2.

On décrira maintenant, en référence aux figures 2 et 3, la structure des plaques 2.We will now describe, with reference to FIGS. 2 and 3, the structure of the plates 2.

Chaque plaque 2 est translucide, voire transparente, et elle est avantageusement constituée en polycarbonate rigide ou en matière analogue présentant d'excellentes propriétés de résistance mécanique, notamment aux chocs, et de résistance au vieillissement, notamment au jaunissement, aux intempéries et à la dégradation de structure. Chaque plaque aura une largeur d'environ deux mètres, qui est la largeur de commercialisation la plus habituelle, et elle sera coupée en longueur à une dimension très légèrement inférieure à la largeur de la piscine à équiper.Each plate 2 is translucent, even transparent, and it is advantageously made of rigid polycarbonate or similar material having excellent properties of mechanical resistance, in particular to impact, and resistance to aging, in particular to yellowing, weathering and degradation. of structure. Each plate will have a width of approximately two meters, which is the most usual marketing width, and it will be cut in length to a dimension very slightly less than the width of the swimming pool to be equipped.

La plaque translucide 2 présente une paroi extérieure continue 7 qui s'étend sur toute la largeur et sur toute la longueur de la plaque, une paroi intérieure discontinue 8, qui est parallèle à la paroi 7 et qui s'étend sur toute la longueur et, de manière discontinue, sur toute la largeur de la plaque, et des parois longitudinales parallèles 9, qui s'étendent sur toute la longueur de la plaque, perpendiculairement aux parois extérieure 7 et intérieure 8 en les réunissant pour définir des groupes d'alvéoles longitudinaux 10 successifs, deux groupes adjacents d'alvéoles successifs étant séparés par un espace longitudinal 11 résultant de l'interruption de la paroi intérieure 8 et étant réunis seulement par la paroi extérieure 7 qui, dans cette zone, constitue une partie de flexion de la plaque pour l'enroulement de celle-ci sur son support, par exemple le tambour 3 de la figure 1.The translucent plate 2 has a continuous outer wall 7 which extends over the entire width and over the entire length of the plate, a discontinuous inner wall 8, which is parallel to the wall 7 and which extends over the entire length and , discontinuously, over the entire width of the plate, and parallel longitudinal walls 9, which extend over the entire length of the plate, perpendicular to the outer 7 and inner 8 walls, bringing them together to define groups of cells longitudinal 10 successive, two adjacent groups of successive cells being separated by a longitudinal space 11 resulting from the interruption of the inner wall 8 and being joined only by the outer wall 7 which, in this area, constitutes a bending part of the plate for winding it on its support, for example the drum 3 of FIG. 1.

Dans l'application de la figure 1, la paroi extérieure 7 définit la surface supérieure du panneau directement exposée aux rayons du soleil, tandis que la paroi intérieure 8 définit la surface inférieure du panneau qui est au contact de l'eau.In the application of Figure 1, the outer wall 7 defines the upper surface of the panel directly exposed to the sun's rays, while the inner wall 8 defines the lower surface of the panel which is in contact with water.

Lors de l'enroulement, la paroi extérieure ou supérieure 7 constitue la surface extérieure de l'enroulement sur le support 3.During winding, the outer or upper wall 7 constitutes the outer surface of the winding on the support 3.

Avantageusement, la paroi extérieure 7 porte un revêtement d'interruption des rayons ultraviolets, ce revêtement étant par exemple constitué par une enduction.Advantageously, the outer wall 7 carries a coating for interrupting ultraviolet rays, this coating being for example constituted by a coating.

La plaque 2 est ainsi constituée d'une succession de groupes 19 de caissons, ces groupes 19 étant séparés par des espaces longitudinaux 11 et étant réunis seulement par la paroi extérieure 7.The plate 2 thus consists of a succession of groups 19 of boxes, these groups 19 being separated by longitudinal spaces 11 and being joined only by the outer wall 7.

Cette structure confère à la plaque une bonne rigidité à la fois dans son plan et perpendiculairement à ce plan, grâce à la présence des groupes de caissons espacés, mais également une souplesse dans les zones de raccordement des groupes d'alvéoles, cette souplesse permettant l'enroulement sur le tambour.This structure gives the plate good rigidity both in its plane and perpendicular to this plane, thanks to the presence of groups of spaced boxes, but also flexibility in the areas of connection of the groups of cells, this flexibility allowing the winding on the drum.

Les alvéoles 10 sont avantageusement emplis d'air, ce qui favorise le passage des rayons solaires pour le chauffage de l'eau, permet la flottabilité de la plaque et assure une isolation thermique correcte.The cells 10 are advantageously filled with air, which favors the passage of the sun's rays for heating the water, allows the buoyancy of the plate and ensures correct thermal insulation.

En particulier, dans l'application préférentielle à une couverture de piscine, et en général pour éviter la pénétration de toute subtance étrangère dans les alvéoles 10, par exemple des poussières, des feuilles ou des petits animaux, les extrémités des alvéoles sont bouchées, comme montré en 12, ces bouchons étant par exemple constitués par un mastic au silicone.In particular, in the preferential application to a swimming pool cover, and in general to avoid the penetration of any foreign substance into the cells 10, for example dust, leaves or small animals, the ends of the cells are blocked, as shown in 12, these plugs being for example constituted by a silicone sealant.

Les plaques 2 sont assemblées bout à bout suivant leur longueur de toute manière appropriée, par exemple par voie mécanique ou, comme montré sur la figure 4, par collage. Pour l'assemblage par collage, on superpose les extrémités longitudinales adjacentes de deux plaques successives 2, ces deux extrémités présentant des groupes 19 qui comportent le même nombre d'alvéoles 10, et on procède aux collages facials de ces deux extrémités, par exemple à l'aide d'une colle 13 au néoprène du type contact qui a l'avantage de résister à l'humidité, d'être incolore et de présenter une très importante résistance à la traction.The plates 2 are assembled end to end along their length in any suitable manner, for example mechanically or, as shown in Figure 4, by gluing. For the assembly by gluing, the adjacent longitudinal ends of two successive plates 2 are superimposed, these two ends having groups 19 which have the same number of cells 10, and the facial gluing of these two ends is carried out, for example at using a neoprene adhesive 13 of the contact type which has the advantage of resisting humidity, being colorless and having a very high tensile strength.

Suivant une caractéristique avantageuse de l'invention, on fait comporter localement aux plaques 2, par exemple dans les zones d'assemblage de deux plaques successives 2, des guides 14 qui débordent au-delà des plaques pour constituer des patins de glissement coopérant avec les parois de l'ouvrage sur lequel le panneau est appliqué, ces parois étant dans les deux applications envisagées soit les parois verticales longitudinales de la piscine, soit les murs du balcon du bâtiment.According to an advantageous characteristic of the invention, the plates 2 are made to include locally, for example in the areas of assembly of two successive plates 2, guides 14 which extend beyond the plates to form sliding pads cooperating with the walls of the structure on which the panel is applied, these walls being in the two applications envisaged either the longitudinal vertical walls of the swimming pool, or the walls of the building's balcony.

La figure 6 illustre une autre caractéristique avantageuse de l'invention, utilisable dans son application à une couverture de piscine.FIG. 6 illustrates another advantageous characteristic of the invention, usable in its application to a swimming pool cover.

Suivant cette caractéristique, la plaque 2 la plus éloignée du tambour d'enroulement 3 présente une partie longitudinale 15 qui est inclinée vers le haut pour former une sorte de spatule de ski ou de patin lors de la mise en place du panneau sur l'eau.According to this characteristic, the plate 2 furthest from the winding drum 3 has a longitudinal part 15 which is inclined upwards to form a sort of ski or skid tip when the panel is placed on the water. .

Cette partie inclinée, par exemple à 45°, est obtenue en fendant longitudinalement la paroi intérieure 8, en faisant fléchir l'extrémité de la plaque par déformation vers l'extérieur de la paroi extérieure 7 et en plaçant une cale 16, par exemple un épais cordon de mastic au silicone, dans l'espace trapézoïdal rectangle ainsi créé.This inclined part, for example at 45 °, is obtained by slitting the inner wall 8 longitudinally, by bending the end of the plate by deformation towards the outside of the outer wall 7 and by placing a shim 16, for example a thick bead of silicone sealant in the rectangular trapezoidal space thus created.

Avantageusement, pour éviter des contraintes excessives de flexion de la paroi extérieure 7 de la plaque 2 la plus voisine du tambour 3, cette première plaque, comme illustrée sur les figures 2 et 3, présente, au moins dans sa partie qui vient coopérer en premier avec le tambour 3, des groupes 19' d'alvéoles 10 en nombre inférieur au nombre des alvéoles des groupes 19 suivants.Advantageously, to avoid excessive bending stresses on the outer wall 7 of the plate 2 closest to the drum 3, this first plate, as illustrated in FIGS. 2 and 3, has, at least in its part which comes to cooperate first with the drum 3, groups 19 ′ of cells 10 in a number less than the number of cells of the following groups 19.

Par exemple les premiers groupes 19' peuvent comporter deux ou trois alvéoles, tandis que les groupes suivants 19 peuvent comporter par exemple cinq alvéoles. Le pas selon lequel les espaces longitudinaux 11 sont ainsi formés est croissant de l'extrémité 17 du panneau la plus proche du tambour d'enroulement vers l'extrémité 18 du panneau la plus éloignée dudit tambour.For example, the first groups 19 ′ can comprise two or three cells, while the following groups 19 can comprise, for example five cells. The pitch according to which the longitudinal spaces 11 are thus formed increases from the end 17 of the panel closest to the winding drum towards the end 18 of the panel farthest from said drum.

Chaque plaque constituant le panneau selon l'invention peut être obtenue soit par extrusion à son profil final, tel que représenté à la figure 2, soit par extrusion d'une plaque dont la paroi intérieure 8 est aussi continue, cette extrusion étant alors suivie par un usinage au cours duquel on enlève localement des bandes longitudinales sur cette paroi 8 pour définir les espaces 11.Each plate constituting the panel according to the invention can be obtained either by extrusion to its final profile, as shown in FIG. 2, or by extrusion of a plate whose inner wall 8 is also continuous, this extrusion then being followed by a machining during which longitudinal strips are removed locally on this wall 8 to define the spaces 11.

La plaque 2 peut être réalisée en toute épaisseur voulue, par exemple de 6 mm à 32 mm. Elle est avantageusement, ainsi qu'il a été dit, réalisée en polycarbonate alvéolaire, cette matière ayant les avantages supplémentaires d'assurer une transmission lumineuse de 82 %, d'être facilement traitée contre les rayons ultraviolets, et d'être d'une faible densité, donc d'une excellente flottabilité grâce à l'air emprisonné dans les alvéoles obturés par des bouchons de mastic au silicone.The plate 2 can be made in any desired thickness, for example from 6 mm to 32 mm. It is advantageously, as has been said, made of cellular polycarbonate, this material having the additional advantages of ensuring a light transmission of 82%, of being easily treated against ultraviolet rays, and of being of a low density, therefore excellent buoyancy thanks to the air trapped in the cells closed by plugs of silicone sealant.

Dans son application à une fermeture de balcon 20, comprenant par exemple une balustrade 21 et une porte-fenêtre coulissante 22, le panneau 1 tel que décrit ci-dessus, réalisé en une ou plusieurs plaques 2 en fonction de la largeur du balcon 20, pourra être déployé soit verticalement si le balcon est fermé à sa partie supérieure par un auvent 23 (figure 7), soit incliné sur l'horizontale si le balcon est à ciel ouvert (figure 8). Selon le cas, le tambour 3 sera alors disposé sous le auvent, à l'aplomb de la balustrade 21 (figure 7) ou au-dessus de la porte-fenêtre 22 (figure 8).In its application to a balcony closure 20, comprising for example a balustrade 21 and a sliding window door 22, the panel 1 as described above, produced in one or more plates 2 as a function of the width of the balcony 20, can be deployed either vertically if the balcony is closed at its upper part by a canopy 23 (Figure 7), or tilted horizontally if the balcony is open (Figure 8). Depending on the case, the drum 3 will then be placed under the awning, directly above the balustrade 21 (FIG. 7) or above the French window 22 (FIG. 8).

Avantageusement, pour faciliter l'opération de déploiement du panneau, et également pour stabiliser ledit panneau après son déploiement, notamment en cas de vent, les deux extrémités longitudinales dudit panneau seront guidées dans des glissières 24 à section en U, fixées aux murs d'encadrement soit verticalement (figure 7), soit selon l'inclinaison désirée (figure 8). Une troisième glissière en U 25, fixée à la balustrade 21, pourra recevoir le bord latéral du panneau déployé le plus éloigné du tambour 3.Advantageously, to facilitate the operation of deploying the panel, and also to stabilize said panel after its deployment, in particular in the event of wind, the two longitudinal ends of said panel will be guided in slides 24 of U section, fixed to the walls of framing either vertically (figure 7), or according to the desired inclination (figure 8). A third U-shaped slide 25, fixed to the balustrade 21, can receive the lateral edge of the deployed panel furthest from the drum 3.

Bien entendu, l'invention n'est pas limitée au mode de réalisation, non plus qu'aux modes d'application, qui ont été décrits ; on pourrait au contraire concevoir diverses variantes sans sortir pour autant de son cadre.Of course, the invention is not limited to the embodiment, nor to the modes of application, which have been described; on the contrary, we could conceive of various variants without departing from its framework.

C'est ainsi, par exemple, que l'on pourrait prévoir, entre les parois extrêmes 7 et 8, une paroi intermédiaire parallèle à celles-ci et, comme la paroi intérieure 8, interrompue localement pour respecter les espaces 11 permettant la flexion de la plaque pour son enroulement.Thus, for example, one could provide, between the end walls 7 and 8, an intermediate wall parallel to them and, like the interior wall 8, interrupted locally to respect the spaces 11 allowing the bending of the plate for its winding.
