Definitions
- the present invention relates to a semi-rigid and floating curtain device intended to cover a swimming pool.
- curtain devices have a major drawback, that of promoting the proliferation of bacteria, constant enemies of swimming pools, owing to the fact that the hinges connecting the blades include cavities where water stagnates, which allows bacteria to grow there, especially when the curtain is rolled up.
- the present invention aims to remedy these drawbacks by proposing a semi-rigid and floating curtain device, making it possible to considerably reduce the risks of the development of bacteria.
- the curtain device according to the invention is essentially characterized in that it comprises panels joined edge to edge in a flexible and sealed manner, each of said panels, produced in one piece by an extrusion process, comprising hollow sections made of rigid plastic, connected longitudinally two by two and tightly by a narrow band made of flexible plastic.
- the outer edge of one of the two end sections of a panel longitudinally have a female hooking element, and the outer edge of the other end section of said panel longitudinally has a male hooking element, the assembly of two contiguous sections being produced by introduction of the male element of a panel in the female element of another panel.
- each of the profiles has a cross section substantially in the form of a ring segment.
- the curtain has peripherally, on its two lateral edges and on its free end edge, a continuous rim projecting upwards.
- At least one of the profiles of a panel has a longitudinal groove below capable of meshing with the projecting longitudinal notches of a drive drum used for winding and during the unfolding of the curtain, said drive drum having a diameter less than the diameter defining the curvature of the underside of a longitudinal section.
- a curtain device according to the invention is thus hinged transversely so as to allow it to be wound on a drum, and the connections between the various profiles and panels are sealed.
- connections between the various panels do not have cavities allowing the water to stagnate when the curtain is rolled up, thus preventing the development of bacteria and molds.
- the shape of the ring segment profiles, associated with a selected diameter of the drive drum has the effect of applying strongly against one another, momentarily, the walls of two contiguous profiles, thus driving out residual water, so that the curtain can be stored practically dry.
- a panel 1 allowing with others to constitute a curtain according to the invention, comprises profiles 10, 11, 12 and 13 connected longitudinally two by two by a fastener 14, the sections 10, 11, 12 and 13 being made of rigid plastic and the fasteners 14 being made of a thin strip of flexible plastic, the assembly being able to be produced in a single operation by extrusion.
- end profile 10 of the panel 1 has a female footprint 2 longitudinally, and that the other end profile 13 has a male footprint 3 longitudinally.
- the female imprint 2 is a longitudinal groove 20, of substantially triangular cross section, formed in the rigid wall of the end profile 10, immediately below the upper plane of the curtain.
- the male imprint 3 made of a flexible plastic material of the same kind as that of the fasteners 14, is a longitudinal bulge 30 of triangular section secured to the end of a fastener 31 itself secured to the upper part of the lateral side profile 13, the bulge 30 being of external dimensions slightly greater than the internal dimensions of the groove 20.
- the bulge 30 has longitudinally lips 32 which are crushed during the force introduction into the groove 20, and which return to their initial position in the groove 20, preventing any infiltration of water.
- the sections 10, 11, 12 and 13 are hollow, and closed at their ends by plugs, not shown, preferably made of flexible plastic.
- plugs can advantageously be secured to one another and have an upward projecting part so as to form a peripheral edge laterally on the curtain, the continuity of this peripheral edge on the free transverse side being able to be ensured by an appropriate element, not shown, introduced for example into the groove 20 of the end profile 10 of the end panel 1 of the curtain.
- Each of the sections 10, 11, 12 and 13 has a cross section substantially in segment of a ring, their lower edge 15 and their upper edge 16 being arcs of concentric circles, and the lateral edges 17 and 18 not being parallel but arranged according to a sector angular, so as to allow the curtain to be wound on a storage drum.
- the lower edge 15 centrally comprises a longitudinal groove 19 intended to allow the meshing of the panels 1 on the notches 40 of a drive roller 4, as can be seen in FIG. 4.
- the drive roller 4 is preferably of a diameter less than the diameter defining the radius of curvature of the lower edge 15 of a profile, so that when passing over the drive roller 4, the side walls 17 and 18 of two contiguous profiles gradually approach each other until they are pressed strongly against each other, thus driving towards the roller 4 the drops of water which could have remained there, the roller 4 being d 'other hand perforated to allow the evacuation of this water.

Description
La présente invention a pour objet un dispositif de rideau semi-rigide et flottant destiné à couvrir une piscine.The present invention relates to a semi-rigid and floating curtain device intended to cover a swimming pool.
On connaît déjà de tels dispositifs de couverture de piscine dont la principale fonction est d'éviter la noyade d'une personne tombant accidentellement dans le bassin.We already know such pool cover devices whose main function is to prevent drowning of a person accidentally falling into the pool.
Ils sont généralement constitués de lames de matière plastique assemblées deux à deux par l'intermédiaire d'une ou plusieurs charnières, ce système d'articulation permettant l'enroulement et le stockage du rideau sur un tambour.They generally consist of plastic blades assembled two by two via one or more hinges, this articulation system allowing the curtain to be rolled up and stored on a drum.
Ces dispositifs de rideau présentent un inconvénient majeur, celui de favoriser la prolifération des bactéries, ennemis constants des piscines, du fait que les charnières reliant les lames comportent des cavités où l'eau stagne, ce qui permet aux bactéries de s'y développer, particulièrement lorsque le rideau est enroulé.These curtain devices have a major drawback, that of promoting the proliferation of bacteria, constant enemies of swimming pools, owing to the fact that the hinges connecting the blades include cavities where water stagnates, which allows bacteria to grow there, especially when the curtain is rolled up.
D'autre part, lorsque la piscine reste couverte pendant une longue période, par exemple l'hiver, les feuilles et autres végétaux qui tombent sur le rideau se décomposent et sont entraînés par les eaux de pluie entre les lames dudit rideau, et se répandent dans l'eau de la piscine en souillant celle-ci.On the other hand, when the pool remains covered for a long period, for example in winter, the leaves and other plants that fall on the curtain decompose and are carried by rainwater between the blades of said curtain, and spread in the pool water by soiling it.
La présente invention vise à remédier à ces inconvénients en proposant un dispositif de rideau semi-rigide et flottant, permettant de réduire considérablement les risques de développement de bactéries.The present invention aims to remedy these drawbacks by proposing a semi-rigid and floating curtain device, making it possible to considerably reduce the risks of the development of bacteria.
Le dispositif de rideau selon l'invention se caractérise essentiellement en ce qu'il comporte des panneaux solidarisés bord à bord de façon souple et étanche, chacun desdits panneaux, réalisé d'une seule pièce par un procédé d'extrusion, comprenant des profilés creux en matière plastique rigide, reliés longitudinalement deux à deux et de façon étanche par une bande de faible largeur réalisée en matière plastique souple.The curtain device according to the invention is essentially characterized in that it comprises panels joined edge to edge in a flexible and sealed manner, each of said panels, produced in one piece by an extrusion process, comprising hollow sections made of rigid plastic, connected longitudinally two by two and tightly by a narrow band made of flexible plastic.
Selon une caractéristique additionnelle du dispositif selon l'invention, le bord extérieur d'un des deux profilés extrêmes d'un panneau comporte longitudinalement un élément d'accrochage femelle, et le bord extérieur de l'autre profilé extrême dudit panneau comporte longitudinalement un élément d'accrochage mâle, l'assemblage de deux profilés contigus étant réalisé par introduction de l'élément mâle d'un panneau dans l'élément femelle d'un autre panneau.According to an additional characteristic of the device according to the invention, the outer edge of one of the two end sections of a panel longitudinally have a female hooking element, and the outer edge of the other end section of said panel longitudinally has a male hooking element, the assembly of two contiguous sections being produced by introduction of the male element of a panel in the female element of another panel.
Selon une caractéristique additionnelle du dispositif selon l'invention, chacun des profilés présente une section transversale sensiblement en forme de segment d'anneau.According to an additional characteristic of the device according to the invention, each of the profiles has a cross section substantially in the form of a ring segment.
Selon une autre caractéristique du dispositif selon l'invention, le rideau comporte périphériquement, sur ses deux bords latéraux et sur son bord extrême libre, un rebord continu saillant vers le haut.According to another characteristic of the device according to the invention, the curtain has peripherally, on its two lateral edges and on its free end edge, a continuous rim projecting upwards.
Selon une autre caractéristique du disposifif selon l'invention l'un au moins des profilés d'un panneau comporte inférieurement une gorge longitudinale apte à s'engrener sur les crans longitudinaux en saillie d'un tambour d'entraînement servant à l'enroulement et au déroulement du rideau, ledit tambour d'entraînement ayant un diamètre inférieur au diamètre définissant la courbure de la face inférieure d'un profilé longitudinal.According to another characteristic of the device according to the invention at least one of the profiles of a panel has a longitudinal groove below capable of meshing with the projecting longitudinal notches of a drive drum used for winding and during the unfolding of the curtain, said drive drum having a diameter less than the diameter defining the curvature of the underside of a longitudinal section.
Un dispositif de rideau selon l'invention est ainsi articulé transversalement de manière à permettre son enroulement sur un tambour, et les liaisons entre les différents profilés et panneaux sont étanches.A curtain device according to the invention is thus hinged transversely so as to allow it to be wound on a drum, and the connections between the various profiles and panels are sealed.
Les liaisons entre les différents panneaux ne comportent d'autre part pas de cavités permettant à l'eau de stagner lorsque le rideau est enroulé, évitant ainsi le développement des bactéries et moisissures.On the other hand, the connections between the various panels do not have cavities allowing the water to stagnate when the curtain is rolled up, thus preventing the development of bacteria and molds.
De plus, la forme des profilés en segment d'anneau, associée avec un diamètre choisi du tambour d'entraînement, a pour effet d'appliquer fortement l'une contre l'autre, momentanément, les parois de deux profilés contigus, chassant ainsi l'eau résiduelle, en sorte que le rideau peut être stocké pratiquement sec.In addition, the shape of the ring segment profiles, associated with a selected diameter of the drive drum, has the effect of applying strongly against one another, momentarily, the walls of two contiguous profiles, thus driving out residual water, so that the curtain can be stored practically dry.
D'autre part, l'eau de pluie ne peut traverser le rideau et entraîner avec elle les végétaux en décomposition, cette eau, canalisée par le rebord périphérique, ruissellant vers le bord d'enroulement jusqu'à un joint transversal qui la dirige vers une rigole d'évacuation.On the other hand, rainwater cannot pass through the curtain and carry with it decaying plants, this water, channeled by the peripheral rim, trickling towards the winding edge up to a transverse joint which directs it towards an evacuation channel.
Enfin, d'un point de vue avantageux, en cas de chute accidentelle d'une personne sur le rideau, celui-ci ne coule pas, d'une part en raison d'une flottabilité accrue, les liaisons souples entre les profilés étant bien moins larges que les charnières classiques, et d'autre part en raison de l'étanchéité de ces liaisons souples, ce qui n'est pas le cas des dispositifs existants où l'eau peut s'infiltrer.Finally, from an advantageous point of view, in the event of an accidental fall of a person on the curtain, the latter does not flow, on the one hand due to increased buoyancy, the flexible connections between the profiles being well narrower than conventional hinges, and on the other hand due to the tightness of these flexible connections, which is not the case with existing devices where water can infiltrate.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Si on se réfère aux figures 1 et 2 on peut voir qu'un panneau 1, permettant avec d'autres de constituer un rideau selon l'invention, comprend des profilés 10, 11, 12 et 13 reliés longitudinalement deux à deux par une attache 14, les profilés 10, 11, 12 et 13 étant en matière plastique rigide et les attaches 14 étant constituées d'une bande de faible épaisseur en matière plastique souple, l'ensemble pouvant être réalisé en une seule opération par extrusion.If we refer to Figures 1 and 2 we can see that a
Si on se réfère également à la figure 3, on peut voir que le profilé extrême 10 du panneau 1 comporte longitudinalement une empreinte femelle 2, et que l'autre profilé extrême 13 comporte longitudinalement une empreinte mâle 3.If reference is also made to FIG. 3, it can be seen that the
L'empreinte femelle 2 est une gorge 20 longitudinale, de section transversale sensiblement triangulaire, pratiquée dans la paroi rigide du profilé extrême 10, immédiatement sous le plan supérieur du rideau.The
L'empreinte mâle 3, réalisée dans une matière plastique souple de même nature que celle des attaches 14, est un renflement longitudinal 30 de section triangulaire solidarisé à l'extrémité d'une attache 31 elle-même solidarisée à la partie supérieure du côté latéral du profilé 13, le renflement 30 étant de dimensions extérieures légèrement supérieures aux dimensions internes de la gorge 20.The
Le renflement 30 comporte longitudinalement des lèvres 32 qui s'écrasent lors de l'introduction en force dans la gorge 20, et qui reprennent leur position initiale dans la gorge 20, empêchant toute infiltration d'eau.The
Les profilés 10, 11, 12 et 13 sont creux, et fermés à leurs extrémités par des bouchons, non représentés, réalisés de préférence en matière plastique souple. Ces bouchons peuvent avantageusement être solidarisés les uns aux autres et comporter une partie saillant vers le haut de manière à former latéralement au rideau un rebord périphérique, la continuité de ce rebord périphérique du côté transversal libre pouvant être assurée par un élément approprié, non représenté, introduit par exemple dans la gorge 20 du profilé extrême 10 du panneau 1 extrême du rideau.The
Chacun des profilés 10, 11, 12 et 13 a une section transversale sensiblement en segment d'anneau, leur bord inférieur 15 et leur bord supérieur 16 étant des arcs de cercles concentriques, et les bords latéraux 17 et 18 n'étant pas parallèles mais disposés selon un secteur angulaire, de manière à permettre l'enroulement du rideau sur un tambour de stockage.Each of the
Le bord inférieur 15 comporte centralement une gorge longitudinale 19 destinée à permettre l'engrènement des panneaux 1 sur les crans 40 d'un rouleau d'entraînement 4, comme cela est visible sur la figure 4.The
Le rouleau d'entraînement 4 est de préférence d'un diamètre inférieur au diamètre définissant le rayon de courbure du bord inférieur 15 d'un profilé, en sorte que lors du passage sur le rouleau d'entraînement 4, les parois latérales 17 et 18 de deux profilés contigus se rapprochent progressivement l'une de l'autre jusqu'à être plaquées fortement l'une contre l'autre, chassant ainsi vers le rouleau 4 les gouttes d'eau qui auraient pu y rester, le rouleau 4 étant d'autre part ajouré afin de permettre l'évacuation de cette eau.The drive roller 4 is preferably of a diameter less than the diameter defining the radius of curvature of the
