Because the cover structure is not stretched above the pool, and the flaps extend at least 20 to 60 cm on the beaches, the number of hooking points necessary to avoid re-entry of the covering structure inside the pelvis following the fall of a body, is considerably reduced.

Description

Domaine technique de l'inventionTechnical field of the invention

L'invention présentée a pour objet une couverture enroulable pour bassins et notamment de piscines, ayant à la fois les caractéristiques d'une couverture isothermique souple, et des fonctions de sécurité pour la protection d'objets ou de personnes lors de leur chute accidentelle dans le bassin, afin d'empêcher leur immersion.The subject of the invention presented is a rollable cover for basins and in particular of swimming pools, having both the characteristics of a flexible isothermal cover, and safety functions to protect objects or people when they fall accidental in the basin, in order to prevent their immersion.

Etat de la technique antérieureState of the prior art

Il existe plusieurs types de couvertures de bassins et en particulier de piscines ayant au moins une des fonctions suivantes :

  • isolation thermique du bassin afin de garder la température de l'eau (couverture d'été)
  • protection du bassin contre les salissures, la chute des feuilles ou des impuretés (couverture d'hiver essentiellement)
  • protection des personnes ou animaux suite à une chute accidentelle dans le bassin, ceci dans certaines conditions.
On peut classer ces couvertures en trois grandes catégories.
  • 1) Les couvertures d'été : Elles flottent en surface du bassin et sont constituées par exemple d'un film souple en polyéthylène comportant des bulles d'air, ou d'un film de 5 à 7 mm en mousse de polyéthylène armée. Ces couvertures n'offrent pas les fonctions hiver, ni de sécurité à la chute d'objets.
    On peut cependant citer le dispositif constituée d'un ensemble de tubes en plastique remplis d'air, et flottant en surface de bassin afin de constituer une sorte de filet offrant des prises en cas de chute dans le bassin. Ce dispositif décrit dans le document US 3 128 478 n'offre pas de fonctions isothermiques. De même on peut citer la couverture décrite dans le document CH 591 617, qui propose d'adjoindre une sorte de filet vertical joignant les bords de la couverture flottante aux plages du bassin ou il est fixé. Mais cette organisation n'offre pas de sécurité notamment en cas de chute sur la couverture flottante elle même.
  • 2) Couvertures d'hiver : ce sont en général des toiles en PVC opaque, ou des filets à mailles très fines (0,5 à 1,5 mm) qui sont tendus au dessus du bassin et arrimés sur les bords par un système de fixation. Ces couvertures ne sont pas en contact avec l'eau du bassin dont le niveau se trouve de 20 à 50 cm en dessous de la toile. Leur mise en place est longue et fastidieuse, et elles nécessitent un système robuste de fixation sur les plages pour leur mise en tension. Ces couvertures n'assurent pas l'isolation thermique donc la fonction d'été, par contre elles peuvent assurer dans certaines conditions de réalisation, une fonction de sécurité suite à une chute accidentelle de corps. Ce type de couverture est par exemple décrit dans le document US 2 958 872. Compte tenu de leur difficulté de mise en place pour un usage quotidien, elles ne sont pas utilisées pendant la période d'utilisation du bassin.
  • 3) Couvertures semi-rigides à barres : elles sont constituées en général d'une feuille en PVC opaque pour le recouvrement du bassin, soutenue par un ensemble de barres transversales au bassin qui reposent sur les plages. Elles assurent à la fois la fonction couverture d'été, la fonction de couverture d'hiver à condition de bien les arrimer aux plages, et une fonction de sécurité après fixation. Selon que la feuille de recouvrement se trouve au dessus ou en dessous de barres transversales, on obtiens différentes caractéristiques décrites dans le document n° FR2637643 de Glatz, ou le document EP 0465430A1 de BIERI, ou encore le document EP 0570311A1 de WALTER. Cependant ces couvertures semi-rigides restent d'un maniement fastidieux, ne présentent pas une bonne esthétique après repli sur la plage, et ont une prise au vent importante, d'où une nécessité de fixation robuste. Leur prix est en moyenne 3 à 4 fois supérieur à celui des couvertures flottantes d'été.
    On peut également citer le document FR2653811 qui décrit une couverture à dimensions variables pour les fonctions été-hiver, constituée d'un matériaux composite de mousse armée en 2 ou 3 couches, avec une bande d'extension pour adapter la taille de la couverture aux besoins été-hiver. Cette couverture présente l'inconvénient de surépaisseurs des bandes d'extension, et n'offre pas la notion de sécurité lorsqu'elle est utilisée en couverture d'été.
    On peut également citer les volets automatiques à lames semi-rigides flottantes pour la couverture de piscine et qui assurent efficacement les fonctions de couverture d'été, d'hiver et de sécurité. Cependant ces dispositifs sont trés peu développés car d'un prix prohibitif.
  • There are several types of cover for pools and in particular for swimming pools with at least one of the following functions:
    • thermal insulation of the pool to keep the water temperature (summer cover)
    • protection of the basin against dirt, falling leaves or impurities (mainly winter cover)
    • protection of people or animals following an accidental fall in the pool, under certain conditions.
    These covers can be classified into three main categories.
  • 1) Summer covers: They float on the surface of the pool and are made, for example, of a flexible polyethylene film comprising air bubbles, or a 5 to 7 mm film of reinforced polyethylene foam. These covers do not offer winter functions, or safety against falling objects.
    However, we can cite the device consisting of a set of plastic tubes filled with air, and floating on the surface of the basin in order to constitute a sort of net offering catches in the event of a fall in the basin. This device described in document US 3 128 478 does not offer isothermal functions. Similarly, we can cite the cover described in document CH 591 617, which proposes to add a kind of vertical net joining the edges of the floating cover to the areas of the basin where it is fixed. But this organization does not offer security, especially in the event of a fall on the floating cover itself.
  • 2) Winter covers: these are generally opaque PVC fabrics, or very fine mesh nets (0.5 to 1.5 mm) which are stretched over the basin and stowed on the edges by a system of fixation. These covers are not in contact with the water in the basin, the level of which is 20 to 50 cm below the canvas. Their installation is long and tedious, and they require a robust system of fixing on the beaches for their tensioning. These covers do not provide thermal insulation therefore the summer function, on the other hand they can ensure in certain conditions of realization, a safety function following an accidental fall of the body. This type of cover is for example described in document US 2,958,872. In view of their difficulty in setting up for daily use, they are not used during the period of use of the basin.
  • 3) Semi-rigid covers with bars: they generally consist of an opaque PVC sheet for covering the basin, supported by a set of bars transverse to the basin which rest on the pads. They provide both the summer cover function, the winter cover function provided they are properly secured to the beaches, and a security function after fixing. Depending on whether the cover sheet is located above or below cross bars, different characteristics are obtained, described in document No. FR2637643 by Glatz, or document EP 0465430A1 by BIERI, or even document EP 0570311A1 by WALTER. However, these semi-rigid covers remain tedious to handle, do not have a good aesthetic after retreating on the beach, and have a significant wind resistance, hence a need for robust fixing. Their price is on average 3 to 4 times higher than that of floating summer blankets.
    We can also cite the document FR2653811 which describes a variable-size blanket for summer-winter functions, made of a composite foam material reinforced in 2 or 3 layers, with an extension band to adapt the size of the blanket to summer-winter needs. This cover has the disadvantage of excess thickness of the extension strips, and does not offer the concept of security when used in summer cover.
    We can also cite the automatic shutters with semi-rigid floating louvers for the pool cover and which effectively perform the summer, winter and safety cover functions. However, these devices are very little developed because of a prohibitive price.
  • De manière générale tous les dispositifs de couverture été-hiver de piscines, pouvant offrir une fonction de sécurité sont soit peu maniables soit très chers, seule la couverture d'été flottante (à bulles,..) est d'un prix très économique, mais n'offre pas de fonction de sécurité.In general, all summer-winter swimming pool cover systems, which can offer a security function are either difficult to handle or very expensive, only the summer cover floating (bubble, etc.) is very economical, but does not offer a safety function.

    Exposé de l'inventionStatement of the invention

    La présente invention décrit une couverture flottante, ayant à la fois les caractéristiques connues d'une couverture d'été isothermique, caractérisée par l'adjonction de moyens de sécurité pour la protection des personnes suite à une chute accidentelle dans le bassin, et pouvant se fabriquer très facilement à partir des matériaux standards connus, à un prix très compétitif. Par ailleurs, compte tenu de ses qualités de légèreté nécessaires aux fonctions de couverture d'été flottante, cette couverture s'enroule très facilement sur un enrouleur à main, ou sur le dispositif décrit dans le brevet FR 2 745 842. La constitution de cette couverture mixte est réalisée principalement par l'association de deux structures, ayant chacune une fonction et des caractéristiques propres :

    • une structure flottante pour la fonction couverture d'été
    • une structure de recouvrement objet de l'invention pour la fonction sécurité, à laquelle est associé un dispositif électronique d'alarme.
    The present invention describes a floating blanket, having both the known characteristics of an isothermal summer blanket, characterized by the addition of safety means for the protection of persons following an accidental fall in the basin, and which can be very easily manufacture from known standard materials, at a very competitive price. Furthermore, given its qualities of lightness necessary for the functions of a floating summer blanket, this blanket can be rolled up very easily on a hand winder, or on the device described in patent FR 2 745 842. The constitution of this mixed hedging is mainly carried out by the association of two structures, each with its own function and characteristics:
    • a floating structure for the summer cover function
    • a covering structure object of the invention for the security function, with which is associated an electronic alarm device.

    Selon l'option de réalisation, la forme et la taille de la structure flottante peut être variable et ne couvrir que tout ou partie la surface du basin, qui peut être de forme libre. Ces deux structures sont liées entre elles mécaniquement par au moins une ligne de fixation ou d'accrochage, continue ou discontinue, située de préférence selon l'axe longitudinal central des deux structures, quand il existe. Dans le cas de certains bassins de forme libre, cette ligne de fixation peut être réduite à une suite de portions de lignes discontinues, ou à un ensemble de points de fixation successifs indépendants. Dans le cas de petits bassins, circulaires en particulier, un seul point central de fixation peut être suffisant. Pour la simplicité de rédaction, on appellera par la suite, ligne de fixation, l'ensemble des différentes organisations en ligne ou en points de fixation cités ci avant.Depending on the implementation option, the shape and size of the floating structure can be variable and cover only all or part of the surface of the basin, which can be free-form. These two structures are mechanically linked together by at least one fixing line or attachment, continuous or discontinuous, preferably located along the central longitudinal axis of the two structures, when it exists. In the case of certain free-form basins, this fixing line can be reduced to one following portions of broken lines, or a set of successive fixing points independent. In the case of small basins, circular in particular, a single central point fixing may be sufficient. For the simplicity of writing, we will call thereafter, line of attachment, all of the different online organizations or attachment points mentioned above before.

    La structure flottante est constituée d'un matériau souple et imputrescible ayant des propriétés isothermiques, avec un traitement anti UV. Le matériau utilisé pour cette structure flottante peut être par exemple du polyéthylène à bulles 400 ou 500 microns (matériau standard), ou une couverture mousse de polyéthylène armé. Cependant, de nombreux autres matériaux utilisés pour les couvertures flottantes, peuvent également convenir.The floating structure is made of a flexible and rot-resistant material having isothermal properties, with anti UV treatment. The material used for this structure floating can be for example bubble polyethylene 400 or 500 microns (material standard), or a reinforced polyethylene foam cover. However, many others materials used for floating blankets, may also be suitable.

    Cette structure flottante une fois installée, se trouve à l'intérieur du bassin, et ses dimensions peuvent être variables selon le degré d'efficacité de la fonction isothermique souhaité. Elle comporte notamment un dispositif de fixation à la structure de recouvrement de sécurité. La structure de recouvrement assurant la sécurité et la protection des personnes à une chute accidentelle dans le bassin, est associée à la structure flottante, et est liée mécaniquement à celle-ci par au moins une ligne de fixation telle que définie ci avant, située de préférence selon l'axe longitudinal aux deux structures quand il existe. Cette structure de recouvrement est indépendante de la structure flottante. Selon la ligne de fixation, la structure de recouvrement se détache du centre de la structure flottante à laquelle elle est liée, pour couvrir toute la surface du bassin et déborder largement des bords du bassin afin d'y être fixée en plusieurs points en périphérie par un dispositif d'accrochage intégré à la plage.
    Dans les conditions normales d'utilisation, la structure de recouvrement est ainsi semi-tendue, sans toutefois faire se soulever la structure flottante. La structure de recouvrement dessine alors un V au dessus de la structure flottante dont la pointe basse centrale se trouve sur la ligne de fixation de la structure flottante. Cette forme en V de la structure de recouvrement, au dessus de la structure flottante, minimise de manière mathématique la profondeur d'immersion d'un corps suite à sa chute sur la structure de recouvrement. Cette forme en V permet également à la structure flottante de rester en contact intime avec le liquide du bassin et de ne pas se soulever, et donc de préserver intégralement les caractéristiques isothermiques initiales de la couverture flottante.
    Pour les bassins de grandes dimension, on pourra avoir plusieurs lignes de fixation à la structure flottante, de préférence contiguës et parallèles. La structure de recouvrement dessinera dans ce cas une sorte de trapèze à la place de V, dont le petit côté qui se substitue à la pointe du V, sera fixé également sur la structure flottante.
    This floating structure, once installed, is located inside the pool, and its dimensions can be variable depending on the degree of efficiency of the desired isothermal function. It notably includes a device for fixing to the safety covering structure. The covering structure ensuring the safety and protection of persons from an accidental fall into the basin, is associated with the floating structure, and is mechanically linked to the latter by at least one fixing line as defined above, located at preferably along the longitudinal axis to the two structures when it exists. This covering structure is independent of the floating structure. According to the fixing line, the covering structure is detached from the center of the floating structure to which it is linked, to cover the entire surface of the basin and extend well beyond the edges of the basin in order to be fixed at several points at the periphery by a hanging device integrated into the beach.
    Under normal conditions of use, the covering structure is thus semi-tensioned, without, however, lifting the floating structure. The covering structure then draws a V above the floating structure, the central lower point of which is on the fixing line of the floating structure. This V-shape of the covering structure, above the floating structure, mathematically minimizes the immersion depth of a body following its fall on the covering structure. This V shape also allows the floating structure to remain in intimate contact with the liquid in the basin and not to rise, and therefore to fully preserve the initial isothermal characteristics of the floating cover.
    For large pools, there may be several lines of attachment to the floating structure, preferably contiguous and parallel. The covering structure will in this case draw a kind of trapezoid in place of V, the short side of which replaces the tip of the V, will also be fixed on the floating structure.

    Les parties de la structure de recouvrement qui débordent du bassin pour recouvrir les plages en périphérie s'appellent rabats. Ces rabats ont une largeur de 20 à 60 cm environ sur les plages. Ces rabats sont de préférence en même matériaux que la structure de recouvrement de sécurité couvrant le bassin, et sont équipés en leur périphérie du nombre nécessaire de dispositifs d'accrochage à la plage, selon la taille du bassin à couvrir. Du fait que la structure de recouvrement n'est pas tendue au dessus du bassin, et que les rabats débordent d'au moins 20 à 60 cm sur les plages, le nombre de points d'accrochage nécessaires afin d'éviter une rentrée de la structure de recouvrement à l'intérieur du bassin suite à la chute d'un corps, est considérablement réduit. Dans des conditions normales d'accrochage aux angles de la structure de recouvrement, un espace de 3 à 5 m entre les points d'accrochage intermédiaires est alors suffisant. Cette architecture réduit de manière très significative le nombre de points d'accrochage, et donc le temps nécessaire à la mise en place et au retrait de cette couverture mixte. Cependant un minimum de quatre points d'accrochage aux quatre angles d'une couverture rectangulaire est souhaitable. Bien évidemment, tous les points d'accrochage sont fixés solidement sur les rabats de la structure de recouvrement de sécurité, à l'aide notamment de sangles de renfort, fixées en périphérie, longitudinalement ou transversalement. De même, les angles recevant les attaches d'accrochage à la plage, ont des renforts d'angles qui peuvent se prolonger jusqu'à la structure flottante. Tous ces dispositifs de renforts, seront selon les matériaux utilisés, cousus, ou soudés, ou collés à la structure de recouvrement de sécurité.
    Lors de l'opération de retrait et d'enroulement de la couverture mixte, les rabats de la structure de recouvrement peuvent être ramenés par pliage sur la structure flottante qui les portera, de façon à faciliter l'enroulement.
    The parts of the covering structure which extend beyond the basin to cover the beaches on the periphery are called flaps. These flaps are approximately 20 to 60 cm wide on the beaches. These flaps are preferably made of the same material as the safety covering structure covering the pool, and are equipped at their periphery with the necessary number of hooking devices to the beach, depending on the size of the pool to be covered. Because the cover structure is not stretched above the pool, and the flaps extend at least 20 to 60 cm on the beaches, the number of hooking points necessary to avoid re-entry of the covering structure inside the pelvis following the fall of a body, is considerably reduced. Under normal conditions of attachment to the corners of the covering structure, a space of 3 to 5 m between the intermediate attachment points is then sufficient. This architecture very significantly reduces the number of attachment points, and therefore the time required to install and remove this mixed cover. However, a minimum of four attachment points at the four corners of a rectangular cover is desirable. Obviously, all the attachment points are securely fixed to the flaps of the safety covering structure, in particular using reinforcement straps, fixed at the periphery, longitudinally or transversely. Likewise, the angles receiving the beach hooks have corner reinforcements which can extend up to the floating structure. All these reinforcement devices will be, depending on the materials used, sewn, or welded, or glued to the safety covering structure.
    During the removal and winding operation of the mixed cover, the flaps of the covering structure can be brought back by folding onto the floating structure which will carry them, so as to facilitate winding.

    Selon un autre mode de réalisation de cette couverture mixte, la structure flottante est liée à la structure de recouvrement de manière non permanente, grâce à des moyens de fixation qui permettent de désolidariser les deux structures et notamment d'enlever la structure flottante ou la structure de recouvrement. A titre d'exemples non limitatifs ces moyens peuvent être des boutons pression en matériaux inoxydables, des crochets, des attaches de type Velcro(marque déposée), des oeillets avec des lacets,... Dans cette configuration, si la structure flottante n'est pas présente, la tension de fixation de la structure de recouvrement peut alors être plus importante.According to another embodiment of this mixed cover, the floating structure is linked to the covering structure in a non-permanent manner, thanks to fixing means which allow to separate the two structures and in particular to remove the floating structure or the overlay structure. By way of nonlimiting examples, these means can be pressure buttons made of stainless materials, hooks, type fasteners Velcro (registered trademark), eyelets with laces, ... In this configuration, if the floating structure is not present, the fixing tension of the covering structure may then be more important.

    La structure de recouvrement (incluant les rabats) est en matériaux souple, inélastique, imputrescible et résistant aux UV. Selon la facilité de fabrication et à titre d'exemples non limitatifs, un certain nombre de matériaux synthétiques peuvent convenir : Nylon(marque déposée), polyéthylène, PVC, polyamide... et leur dérivés. Cette structure de recouvrement pourra dans un premier mode de réalisation, être en tissu plein dont la matière sera choisie parmi les matériaux cités. Son épaisseur dépendra de la résistance mécanique du matériau utilisé afin qu'elle résiste à la chute accidentelle d'un corps. Compte tenu que cette bâche n'est pas tendue complètement à l'horizontale, mais qu'elle forme un V pour venir en contact avec la ligne de fixation au centre de la structure flottante, la résistance mécanique nécessaire est nettement réduite. Aussi une bâche de 0,1 à 1 mm d'épaisseur devrait convenir (équipée des renforts cités ci-avant).The covering structure (including the flaps) is made of flexible, inelastic material, rotproof and UV resistant. According to the ease of manufacture and as examples not restrictive, a certain number of synthetic materials may be suitable: Nylon (brand deposited), polyethylene, PVC, polyamide ... and their derivatives. This covering structure may in a first embodiment, be in solid fabric whose material will be chosen among the materials cited. Its thickness will depend on the mechanical resistance of the material used to resist accidental falling of a body. Given that this tarpaulin is not completely horizontal, but forms a V to come into contact with the fixing line in the center of the floating structure, the mechanical resistance required is significantly reduced. Also a tarpaulin 0.1 to 1 mm thick should be suitable (equipped with the reinforcements mentioned above).

    De manière préférentielle dans un deuxième mode de réalisation, la structure de recouvrement est de type filet à larges mailles plutôt qu'une bâche en tissu plein. En effet la structure filet permet de gagner selon le cas un facteur 5 à 10 sur le poids de la structure de recouvrement, ce qui facilite grandement sa manipulation ainsi que sa flottabilité lors du repliement des rabats sur la structure flottante, et permet ainsi de manière très aisée l'enroulement, sur un enrouleur à main, ou motorisé tel que celui décrit dans le document FR 2 745 842, ou sur un autre dispositif de retrait et de stockage de l'ensemble de cette couverture mixte : structure flottante et structure de recouvrement repliée sur celle-ci.
    De même, la mise en place de cette couverture mixte sera grandement facilitée et possible à partir des enrouleurs connus, précités et conçus pour les couvertures d'été flottantes.
    Preferably in a second embodiment, the covering structure is of the net type with large meshes rather than a full fabric tarpaulin. In fact, the net structure makes it possible to gain a factor of 5 to 10 depending on the weight of the covering structure, which greatly facilitates its handling as well as its buoyancy when the flaps are folded over the floating structure, and thus allows very easy winding, on a hand winder, or motorized such as that described in document FR 2 745 842, or on another device for removing and storing all of this mixed cover: floating structure and structure cover folded over there.
    Similarly, the installation of this mixed cover will be greatly facilitated and possible from the known reels, mentioned above and designed for floating summer covers.

    Le filet de la structure de recouvrement ayant un rôle de protection des personnes, et non pas un rôle de protection aux salissures comme le sont les filets des couvertures d'hiver, il s'en suit que les mailles du filet de la structure de recouvrement sont assez larges, ce qui diminue le poids global. A titre indicatif, des mailles carrées, rectangulaires ou en forme de losanges ou autres motifs, dont les côtés sont compris entre 1 et 10 cm sont suffisantes. Cependant, rien n'interdit des mailles plus fines.
    Pour les mêmes raisons que citées pour une structure de recouvrement en tissu plein, la résistance mécanique nécessaire est réduite, du fait que le filet n'est pas tendu au dessus du bassin, mais qu'il forme un V dont la pointe centrale est liée mécaniquement à la ligne de fixation de la structure flottante reposant en surface du bassin à protéger. Dans ces conditions les forces de résistance à la chute d'un corps pour son maintien en surface du bassin sont réduites, ce qui réduit d'autant le diamètre du fil de la maille. Selon la taille de la maille et le matériau final choisi, on prendra typiquement des diamètres de fil compris entre 1 et 4 mm selon une relation : large maille avec gros diamètre de fil, petite maille avec petit diamètre de fil.
    The net of the covering structure having a protective role for people, and not a protective role against dirt as are the nets of winter blankets, it follows that the mesh of the net of the covering structure are quite wide, which decreases the overall weight. As an indication, square, rectangular or diamond-shaped or other patterns, the sides of which are between 1 and 10 cm are sufficient. However, nothing prohibits finer meshes.
    For the same reasons as mentioned for a covering structure in solid fabric, the necessary mechanical resistance is reduced, because the net is not stretched over the pelvis, but forms a V whose central point is linked mechanically to the fixing line of the floating structure resting on the surface of the basin to be protected. Under these conditions the forces of resistance to the fall of a body to maintain it on the surface of the pelvis are reduced, which correspondingly reduces the diameter of the mesh wire. Depending on the size of the mesh and the final material chosen, we will typically take wire diameters between 1 and 4 mm according to a relationship: large mesh with large wire diameter, small mesh with small wire diameter.

    Afin d'améliorer la sécurité de la couverture mixte, on associe à la structure de recouvrement un dispositif électronique d'alarme qui déclenche une alarme suite à la détection des chocs ou des vibrations produites sur la structure de recouvrement. Ce dispositif est constitué de détecteurs connus de vibrations. Deux classes de détecteurs sont cités à titre d'exemple :

    • Des détecteurs de vibrations à inertie : accéléromètres 1, 2, ou 3 axes, détecteurs à masselottes inertielles, détecteurs à bulle de mercure, détecteur piezo-elctrique fournissant un signal proportionnel au choc. Ces détecteurs chacun se trouvent dans un boítier étanche, et sont directement placés sur la structure de recouvrement, de préférence sur la partie descendante du V, juste après le bord du bassin.
    • Des détecteurs de vibrations ou de chocs à déformation mécanique : ils produisent suite à cette déformation, une variation par exemple de résistivité, ou de champ magnétique, ou plus simplement l'enclenchement d'un contact électrique. Ces détecteurs à déformation sont mis chacun dans un boítier, qui est en série entre un point de fixation de la plage et la structure de recouvrement.
    Quel que soit le type de détecteur retenu, celui-ci est relié à un boítier de commande qui dispose notamment de moyens de stockage de l'énergie électrique nécessaire à son autonomie. Ces moyens pourrons être des piles électrochimiques, des accumulateurs rechargeables, ou des cellules solaires.In order to improve the security of the mixed cover, the cover structure is associated with an electronic alarm device which triggers an alarm following the detection of shocks or vibrations produced on the cover structure. This device consists of known vibration detectors. Two classes of detectors are cited by way of example:
    • Inertial vibration detectors: 1, 2 or 3-axis accelerometers, inertial flyweight detectors, mercury bubble detectors, piezoelectric detector providing a signal proportional to the shock. These detectors each are located in a waterproof housing, and are directly placed on the covering structure, preferably on the descending part of the V, just after the edge of the basin.
    • Detectors of vibration or shock with mechanical deformation: they produce following this deformation, a variation for example of resistivity, or of magnetic field, or more simply the engagement of an electrical contact. These deformation detectors are each placed in a housing, which is in series between a point of attachment of the range and the covering structure.
    Whatever type of detector selected, it is connected to a control unit which has in particular means for storing the electrical energy necessary for its autonomy. These means could be electrochemical cells, rechargeable batteries, or solar cells.

    Lors de la chute accidentelle d'un corps sur la structure de recouvrement, ce choc est détecté par le dispositif détecteur de vibrations qui fournit un signal électrique au boítier de commande. Ce signal est comparé à un seuil réglable fixé par l'utilisateur. Si le signal dépasse le seuil d'alerte fixé, un signal d'alarme est généré et déclenche alors une alarme pouvant être par exemple du type : sonore (sirènes...), visuelle (lumières - projecteurs). Cette alarme peut être produite localement par le boítier de commande, ou de manière préférentielle pour limiter l'énergie électrique à stocker dans le boítier de commande, le signal d'alarme est transmis par des moyens radio à un poste central distant, qui déclenche alors les alarmes sonores, visuelles, ou appels téléphoniques à des numéros enregistrés dans ce central. During the accidental fall of a body on the covering structure, this shock is detected by the vibration detector device which provides an electrical signal to the ordered. This signal is compared to an adjustable threshold set by the user. If the signal exceeds the set alert threshold, an alarm signal is generated and then triggers an alarm which may for example be of the type: sound (sirens, etc.), visual (lights - projectors). This alarm can be generated locally by the control unit, or in a way preferential to limit the electrical energy to be stored in the control box, the alarm signal is transmitted by radio means to a remote central station, which triggers then audible, visual, or telephone alarms to numbers recorded in this central.

    La disparition de l'alarme se fait par une action manuelle sur un bouton situé soit sur le boítier de commande installé prés de la structure de recouvrement, soit sur le poste central distant quand il existe.The alarm disappears by manual action on a button located either on the control unit installed near the covering structure, either on the central station distant when it exists.

    Selon une forme intégrée de réalisation, le boítier de commande est supprimé, et d'une part l'ensemble de ses moyens d'enregistrement et de comparaison au seuil sont transférés dans le poste central, et d'autre part ses moyens radio et énergie sont intégrés au boítier du ou des détecteurs de vibration fixés à la structure de recouvrement.
    L'ensemble de ce dispositif d'alarme est conçu de manière autonome et indépendante, afin d'équiper, soit la structure de recouvrement décrite ici, soit tout autre dispositif déjà connu ou à venir de couverture de piscines ou autres.
    L'invention décrite ici permet d'adjoindre aux caractéristiques connues des couvertures flottantes d'été, des caractéristiques de sécurité pour la protection des personnes, tout en préservant les qualités de maniabilité et de prix de ces couvertures.
    According to an integrated embodiment, the control unit is eliminated, and on the one hand all of its recording and comparison means at the threshold are transferred to the central station, and on the other hand its radio and energy means are integrated into the housing of the vibration detector (s) fixed to the covering structure.
    The whole of this alarm device is designed autonomously and independently, in order to equip either the covering structure described here, or any other device already known or to come with swimming pool cover or the like.
    The invention described here makes it possible to add to the known characteristics of floating summer covers, safety characteristics for the protection of persons, while preserving the maneuverability and price qualities of these covers.

    Description détaillée de modes de réalisations de l'inventionDetailed description of embodiments of the invention

    En référence aux figures 1 et 2, une première structure flottante (2) isothermique épouse la forme intérieure du bassin. Cependant, dans certains cas de réalisation non représentés dans les figures 1 et 2, la structure flottante(2) couvre en tout ou partie la surface intérieure du bassin délimité par des bords (5). Une deuxième structure de recouvrement (3) se trouve au dessus de la structure flottante (2) et est liée mécaniquement à la structure flottante (2) par au moins une ligne de fixation (4) qui se trouve de manière avantageuse selon l'axe longitudinal des deux structures.(2,3) Cet axe sera de préférence l'axe de symétrie longitudinal quand il existe, de chacune des deux structures.
    Cette ligne de fixation (4) peut être continue ou discontinue, ou constituée d'un ensemble de points successifs, et pour les bassins de petite dimension ou circulaires non représentés sur la figure 1, elle peut être réduite à un seul point de fixation. Pour des bassins de grande dimension on peut avoir pour des raisons de solidité plusieurs lignes de fixation (4) non représentées sur les figures 1 et 2, et mises de préférence selon l'axe longitudinal central quand il existe. Ces lignes seront de préférence contiguës et parallèles et espacées de quelques millimètres à quelques centimètres. Dans ce cas la forme en V de la structure de recouvrement(3) est élargie à la pointe du V, et dessine alors un trapèze non représenté sur la figure 2, dont le petit côté se substitue à la pointe du V, et est constitué de l'ensemble des lignes de fixation(4) fixées à la structure flottante (2).
    With reference to FIGS. 1 and 2, a first isothermal floating structure (2) follows the interior shape of the basin. However, in certain embodiments not shown in FIGS. 1 and 2, the floating structure (2) covers all or part of the interior surface of the basin delimited by edges (5). A second covering structure (3) is located above the floating structure (2) and is mechanically linked to the floating structure (2) by at least one fixing line (4) which is advantageously located along the axis. longitudinal of the two structures. (2,3) This axis will preferably be the longitudinal axis of symmetry when it exists, of each of the two structures.
    This fixing line (4) can be continuous or discontinuous, or made up of a set of successive points, and for small or circular basins not shown in FIG. 1, it can be reduced to a single fixing point. For large basins, for reasons of solidity, it is possible to have several fixing lines (4) not shown in FIGS. 1 and 2, and preferably placed along the central longitudinal axis when there is one. These lines will preferably be contiguous and parallel and spaced a few millimeters to a few centimeters. In this case the V-shape of the covering structure (3) is widened at the tip of the V, and then draws a trapezoid not shown in Figure 2, the short side of which replaces the tip of the V, and is made up of all the fixing lines (4) fixed to the floating structure (2).

    Selon la ou les lignes de fixation (4) les deux structures(2,3) peuvent être liées de manière permanente et inamovible (collage, soudage, polymérisation, couture), ou de manière avantageuse représentée sur les figures 1 et 2, ces deux structures sont liées par des moyens d'assemblage (8), permettant le démontage et la séparation physique des structures(2) et (3) et le réassemblage de ces deux structures. Ces moyens (8), à titre d'exemple peuvent être : des boutons pression en matériaux inoxydables, des crochets, des bandes adhésives type Velcro (marque déposée), des attaches avec lacets et oeillets en correspondance sur les deux structures...
    La structure de recouvrement(3) est de type filet à larges mailles de 1 à 10 cm de côté, en matériaux souple, inélastique, résistant aux UV, et imputrescible. Le choix se portera sur des matériaux connus en Nylon(marque déposée), polyéthylène, polyamide, PVC...
    According to the attachment line (s) (4), the two structures (2,3) can be permanently and irremovably linked (bonding, welding, polymerization, sewing), or advantageously shown in FIGS. 1 and 2, these two structures are linked by assembly means (8), allowing the dismantling and physical separation of structures (2) and (3) and the reassembly of these two structures. These means (8), by way of example, can be: press studs made of stainless materials, hooks, Velcro type adhesive strips (registered trademark), fasteners with laces and eyelets corresponding to the two structures ...
    The covering structure (3) is of the net type with large meshes of 1 to 10 cm per side, made of flexible, inelastic, UV-resistant and rot-proof materials. The choice will be made on known materials in Nylon (registered trademark), polyethylene, polyamide, PVC ...

    Comme le montre la figure 2 à titre d'exemple de réalisation, la structure de recouvrement (3) forme un V dont la pointe basse est attachée à la première structure flottante (2) sur la ligne de fixation(4), et dont les deux côtés du V se détachent de l'axe (4) et remontent jusqu'aux bords (5) du bassin, et se prolongent de 20 à 60 cm pour former des rabats (9) qui reposent alors sur une plage (7).
    En périphérie des rabats (9), la structure de recouvrement (3) est équipée d'au moins une sangle ou d'un cordon de renfort (10) fixé solidement à la structure (3). De même dans les angles sont fixés des renforts d'angles (11) qui se prolongent vers l'intérieur de la structure (3) au moins jusqu'à ce que celle-ci ne soit plus en contact direct avec les plages (7). Des bandes de protection (12) de 10 à 15 cm de large, figure 2, sont également fixées sous la structure de recouvrement (3) afin de protéger celle-ci des contacts directs des bords (5) du bassin. De manière générale tous ces renforts ou protections (10), (11), (12) ont les caractéristiques suivantes :

    • ils utilisent des matériaux ayant les mêmes types de caractéristiques que ceux déjà cités,
    • ils sont fixés solidement à la structure (3) par tous moyens connus : collage, soudage, polymérisation, coutures,
    • ils prennent en "sandwich" la structure (3), mais de manière préférentielle pour des raisons de diminution de poids, ils peuvent être fixés uniquement sous la structure de recouvrement (3) afin de la protéger des frottements sur la plage (7) ou les bords (5) du bassin.
    As shown in FIG. 2 as an example of an embodiment, the covering structure (3) forms a V, the low point of which is attached to the first floating structure (2) on the fixing line (4), and whose two sides of the V detach from the axis (4) and go up to the edges (5) of the pelvis, and extend from 20 to 60 cm to form flaps (9) which then rest on a pad (7).
    At the periphery of the flaps (9), the covering structure (3) is equipped with at least one strap or a reinforcing cord (10) fixed securely to the structure (3). Similarly in the corners are fixed reinforcements of angles (11) which extend towards the inside of the structure (3) at least until the latter is no longer in direct contact with the pads (7) . Protective strips (12) 10 to 15 cm wide, FIG. 2, are also fixed under the covering structure (3) in order to protect the latter from direct contact with the edges (5) of the basin. In general, all these reinforcements or protections (10), (11), (12) have the following characteristics:
    • they use materials having the same types of characteristics as those already mentioned,
    • they are securely fixed to the structure (3) by any known means: bonding, welding, polymerization, seams,
    • they sandwich the structure (3), but preferably for reasons of weight reduction, they can be fixed only under the covering structure (3) in order to protect it from friction on the deck (7) or the edges (5) of the basin.

    Comme le montre la figure 2, la structure de recouvrement (3) est semi-tendue et fixée à la plage (7) grâce à des moyens d'accrochage (13) réglables attachés à des pitons(14) de préférence escamotables pris dans la plage (7). En référence à la figure 1, ces moyens d'accrochage (13) se trouvent au moins aux quatre angles de la structure de recouvrement (3) et selon la largeur des rabats (9) reposant sur la plage on interpose un ou plusieurs moyens (13) sur les côtés de la structure (3), en appliquant la relation : plus la largeur des rabats est importante et plus l'espace entre les points de fixation peut être important. A titre d'exemple; pour des rabats dont la largeur est de 60 cm reposant sur la plage, et à condition que les moyens d'accrochage (13) aux quatre angles soient correctement assurées, l'espace entre deux points d'accrochage (13) latéraux sera de 5 m. Bien évidemment, un espace inférieur peut être retenu. As shown in Figure 2, the cover structure (3) is semi-tensioned and fixed to the range (7) thanks to adjustable hooking means (13) attached to pegs (14) of preferably retractable taken in the range (7). Referring to Figure 1, these means attachment (13) are at least at the four corners of the covering structure (3) and depending on the width of the flaps (9) resting on the beach, one or more means are interposed (13) on the sides of the structure (3), applying the relation: the more the width of the flaps important and more the space between the fixing points can be important. For exemple; for flaps whose width is 60 cm resting on the beach, and provided that the hooking means (13) at the four corners are properly secured, the space between two lateral hooking points (13) will be 5 m. Obviously, a lower space can be retained.

    La figure 3 représente la structure de recouvrement (3) équipée d'un dispositif électronique d'alarme constitué selon un premier mode de réalisation, d'un boítier de commande (20) et de un ou plusieurs détecteurs de vibrations ou chocs.
    Un détecteur de vibrations de type à déformation mécanique (21) est mis dans un boítier qui est en série entre un point d'accrochage (22) et la structure de recouvrement (3). De manière avantageuse on choisira un détecteur de vibrations du type à inertie (23) mis dans un boítier étanche (36) qui sera installé préférentiellement sur la partie descendante du V de la structure de recouvrement (3), entre un bord (5) du bassin, et la ligne de fixation (4). Quels que soient le, ou les détecteurs présents, ceux-ci sont reliés au boítier de commande (20), soit électriquement par des câbles (38), soit par des moyen de communication radio(28) mis dans leur boítier et non représentés sur la figure 3. Le boítier de commande(20) dispose notamment des moyens (25) de production par des cellules solaires ou de stockage dans des batteries de l'énergie électrique nécessaire à son autonomie.
    A la suite d'une vibration sur la structure (3) le ou les détecteurs actifs (21 ou 23) transmettent un signal de vibration au boítier (20). Ce signal est comparé à un seuil d'alerte enregistré, grâce à des moyens électroniques de comparaison (37). Ce seuil d'alerte est réglable et enregistré par les moyens manuels (24). Si ce signal de vibration dépasse le seuil d'alerte enregistré, un signal d'alarme est généré qui déclenche alors une alarme locale sonore (26) ou lumineuse (27). De manière préférentielle cette alarme est transmise par des moyens de communication radio (28) à un poste central distant (29) qui dispose également de moyens radio (28) de réception, et qui déclenche alors ses propres alarmes sonores (30) ou visuelles (31), ou compose des numéros de téléphone enregistrés, grâce à des moyens (32).
    Ce central distant (29) est alimenté en énergie par le secteur (33), et peut fonctionner en autonomie totale en cas de coupure de courant du réseau électrique, grâce à des batteries rechargeables (34) qui suppléent alors ce réseau.
    La disparition de l'alarme suite à son déclenchement, se fait par une action manuelle sur le bouton (35) du boítier de commande (20).
    Figure 3 shows the covering structure (3) equipped with an electronic alarm device constituted according to a first embodiment, a control box (20) and one or more vibration or shock detectors.
    A mechanical deformation type vibration detector (21) is placed in a housing which is in series between a hooking point (22) and the covering structure (3). Advantageously, a vibration detector of the inertia type (23) will be chosen, placed in a sealed housing (36) which will preferably be installed on the descending part of the V of the covering structure (3), between an edge (5) of the basin, and the fixing line (4). Whatever the detector (s) present, these are connected to the control box (20), either electrically by cables (38), or by radio communication means (28) placed in their box and not shown on Figure 3. The control unit (20) has in particular means (25) for production by solar cells or storage in batteries of the electrical energy necessary for its autonomy.
    Following a vibration on the structure (3) the active detector or detectors (21 or 23) transmit a vibration signal to the housing (20). This signal is compared to a recorded alert threshold, thanks to electronic comparison means (37). This alert threshold is adjustable and recorded by manual means (24). If this vibration signal exceeds the recorded alert threshold, an alarm signal is generated which then triggers a local audible (26) or light (27) alarm. Preferably, this alarm is transmitted by radio communication means (28) to a remote central station (29) which also has radio reception means (28), which then triggers its own audible (30) or visual alarms ( 31), or dials recorded telephone numbers, by means (32).
    This remote central (29) is supplied with energy by the sector (33), and can operate in total autonomy in the event of a power cut in the electrical network, thanks to rechargeable batteries (34) which then replace this network.
    The disappearance of the alarm following its triggering is done by manual action on the button (35) of the control unit (20).

    Selon un deuxième mode intégré de réalisation de l'invention, le boítier de commande (20) est supprimé, ses fonctions étant alors déportées, et d'une part,

    • les moyens manuels (24) de réglage et d'enregistrement du seuil d'alerte,
    • les moyens électroniques de comparaison(37),
    • le bouton (35) de suppression d'alarme, sont déportés dans le poste central (29) distant,
      et d'autre part,
    • les moyens (25) de production par des cellules solaires ou de stockage d'énergie électrique,
    • les moyens de communication radio (28) du signal de vibration, sont intégrés dans les boítiers de chacun des détecteurs (21) ou (23). Dans cette forme intégrée de réalisation, les câbles (38) sont inutiles, et les détecteurs de vibration deviennent complètement autonomes et indépendants.
    Selon cette forme intégrée de réalisation, suite à la détection d'un choc sur la structure (3) le signal est transmis directement par les moyens radio (28) des détecteurs, au poste central (29) distant, qui réalise grâce aux moyens (24), (37), (35), l'intégralité des traitements déjà décrits dans le mode précédent.According to a second integrated embodiment of the invention, the control unit (20) is eliminated, its functions then being remote, and on the one hand,
    • the manual means (24) for adjusting and recording the alert threshold,
    • electronic comparison means (37),
    • the alarm suppression button (35) are deported to the remote central station (29),
      And on the other hand,
    • the means (25) of production by solar cells or storage of electrical energy,
