Abstract

The cover has a main beam (1) which is attached to the ground by a clevis (2) and is reinforced by a pillar (3) which is also fixed to the ground. These are joined by a metal housing (5) which supports the axis of the dome (6). The fixed part of the dome consists of 14 arcs (7) fixed to the ground and joined by two metal plates (8) which are attached to the axis (6). Reinforcements between the arcs are used to increase rigidity and allow the Plexiglass (RTM) to be attached. The four rotating sections are each made up of 5 arcs (10) attached to beams at the base (11). The are joined by metal sections (13) at the top. Each rotating beam (11) has four teflon (RTM) rollers (14) and nylon brushes to make the joints waterproof. The axis consists of a support (16) with a threaded rod (17) on which is placed a carbon seal (18), a steel washer (19), another carbon seal, a metal section (13) and so on. The fixed section covers 120 degrees, the rotating sections cover 240 degrees. The sections are designed so that they cannot jam. The frame for the fixed and mobile sections are made of laminated and glued wood which allows the cover to be either round or elliptical. The cover is made of double walled Plexiglas to limit heat loss. Each rotating section can be fixed to the ground when it is in its closed position. When the cover is completely closed it can be locked.

Description

La présente invention concerne un abri utilisable en particulier pour une piscine et adaptable à toute forme de bassin. The present invention relates to a shelter which can be used in particular for a swimming pool and which can be adapted to any form of basin.

Une piscine d'extérieur est soumise aux intempéries, ce qui entraîne une modification très fréquente du PH de l'eau, de son niveau à cause des précipitations ainsi que de la pollution par apport de feuilles, poussières, bactéries, fientes d'oiseaux et autres détritus. En outre, la déperdition calorifique est importante et le vent gêne très souvent le baigneur. Cet abri présente de surcroît un atout important au niveau de la sécurité vis-àvis des enfants et des animaux. An outdoor swimming pool is subject to bad weather, which results in a very frequent change in the pH of the water, its level due to precipitation as well as pollution by the addition of leaves, dust, bacteria, bird droppings and other litter. In addition, the heat loss is significant and the wind very often annoys the bather. This shelter also has an important advantage in terms of safety for children and animals.

Avec d'excellentes conditions météorologiques, il est beaucoup plus agréable d'utiliser une piscine non couverte. Les dispositifs de couverture existants présentent l'inconvénient de ne pas découvrir le bassin intégralement et de ne pas être manipulable facilement par une seule personne. With excellent weather conditions, it is much more pleasant to use an uncovered swimming pool. The existing covering devices have the disadvantage of not uncovering the entire basin and of not being easy to handle by one person.

Le dispositif, selon l'invention, permet de remédier aux inconvénients cidessus tout en conservant l'avantage d'un bassin entièrement découvrable et présente aussi l'intérêt d'une ouverture modulable à volonté. ll est donc possible d'être abrité du vent, quelle que soit sa direction, tout en ayant un bassin en grande partie découvert. Le fonctionnement de l'ensemble est très doux, ne nécessite pas d'effort important, et ne peut pas se bloquer. Toutefois, une motorisation peut être effectuée pour un confort accru. The device according to the invention overcomes the above drawbacks while retaining the advantage of a fully discoverable basin and also has the advantage of a modular opening at will. It is therefore possible to be sheltered from the wind, whatever its direction, while having a largely uncovered pool. The operation of the assembly is very smooth, does not require significant effort, and cannot be blocked. However, a motorization can be carried out for increased comfort.

L'abri comprend un secteur fixe de 120 degrés et un ensemble mobile de 240 degrés composé lui-même de quatre secteurs tournants pouvant coulisser les uns dans les autres. L'ensemble des quatre parties tournantes coulisse dans la partie fixe. The shelter comprises a fixed sector of 120 degrees and a mobile assembly of 240 degrees itself composed of four rotating sectors which can slide into each other. All four rotating parts slide in the fixed part.

L'axe de la coupole est positionné à la verticale du bord de la piscine situé côté partie fixe ; le bassin peut donc se trouver intégralement à l'air libre. Le système présente aussi l'intérêt d'une ouverture modulable à volonté et permet donc d'être abrité du vent quelle qu'en soit la direction. The axis of the dome is positioned vertical to the edge of the pool located on the fixed part side; the basin can therefore be entirely in the open air. The system also has the advantage of an adjustable opening at will and therefore makes it possible to be sheltered from the wind regardless of the direction.

Pour des motifs d'esthétique, la section de la coupole a une forme en quart d'ellipse (toute autre forme étant possible). Pour respecter cette forme, il est fait appel au procédé du bois lamellé collé, traité antifongique. Toutes les pièces métalliques utilisées seront en acier inoxydable. For aesthetic reasons, the section of the dome has a quarter ellipse shape (any other shape is possible). To respect this shape, the glued laminated wood process, treated with antifungal, is used. All metal parts used will be made of stainless steel.

Le dispositif selon l'invention comporte une poutre principale en bois, fixée au sol par une chape métallique. Un pilier de renfort en bois est fixé sous l'extrémité de cette poutre et est également fixé au sol par une chape. The device according to the invention comprises a main wooden beam, fixed to the ground by a metal yoke. A wooden reinforcing pillar is fixed under the end of this beam and is also fixed to the ground by a screed.

L'extrémité de la poutre supporte l'axe de l'abri.  The end of the beam supports the axis of the shelter.

La charpente du préau, c'est-à-dire de la partie fixe, est constituée de treize arcs en bois, fixés à l'axe de l'abri d'une part, et au sol d'autre part par des ferrures métalliques appropriées. The frame of the courtyard, that is to say of the fixed part, consists of thirteen wooden arches, fixed to the axis of the shelter on the one hand, and to the ground on the other hand by metal fittings appropriate.

Chaque secteur tournant est composé de cinq arcs en bois fixés en partie haute à l'axe de l'abri et en partie basse à une poutre circulaire. Cette poutre comporte:
- quatre roulettes en téflon montées sur roulements à billes
- des balais en nylon pour l'étanchéité avec le sol.
Each rotating sector is made up of five wooden arches fixed at the top to the axis of the shelter and at the bottom to a circular beam. This beam includes:
- four teflon castors mounted on ball bearings
- nylon brushes for sealing with the ground.

Un boîtier métallique comprenant deux joues vient coiffer l'extrémité de la poutre principale et son pilier de renfort. L'ensemble est boulonné. A metal housing comprising two cheeks covers the end of the main beam and its reinforcing pillar. The assembly is bolted.

Ce boîtier supporte l'axe de l'abri. This box supports the axis of the shelter.

Les arcs de chaque secteur tournant sont fixés à une pièce métallique dont la forme est celle d'une portion de cylindre aplati. The arcs of each rotating sector are fixed to a metal part whose shape is that of a flattened cylinder portion.

Les quatre fixations sont empilées sur l'axe de l'abri et espacées par des disques de carbone permettant un fonctionnement doux ne nécessitant aucun graissage. The four fixings are stacked on the axis of the shelter and spaced by carbon discs allowing a smooth operation requiring no lubrication.

En partie haute de l'axe, sont fixés les arcs du préau. Ils sont boulonnés en sandwich entre deux plaques métalliques. In the upper part of the axis, the arches of the courtyard are fixed. They are sandwiched between two metal plates.

L'axe proprement dit est un fourreau en acier inoxydable maintenu par une tige filetée. The axis itself is a stainless steel sheath held by a threaded rod.

Couverture:
Jusqu'à hauteur d'homme, elle est réalisée en double parois de plexiglas transparent de 4 mm d'épaisseur.
Blanket:
Up to human height, it is made of double walls of transparent plexiglass 4 mm thick.

La partie supérieure est réalisée en polycarbonate alvéolé de 10 mm d'épaisseur. The upper part is made of 10 mm thick honeycomb polycarbonate.

La fixation des plaques de plexiglas et polycarbonate est effectuée avec des parcloses. The fixing of the plexiglass and polycarbonate sheets is carried out with glazing beads.

Une circulation d'air est favorisée entre les deux parois de plexiglas et polycarbonate afin d'éviter les condensations. Cette circulation d'air est favorisée par l'échauffement solaire. Air circulation is encouraged between the two walls of plexiglass and polycarbonate in order to avoid condensation. This air circulation is favored by solar heating.

En référence à ces dessins, le dispositif comporte une poutre principale ( { ) ancrée au sol par l'intermédiaire d'une chape (2) et renforcée par un pilier (3 ) lui-même fixé au sol par une chape (4 ). Ces deux poutres sont réunies en partie haute par un boîtier métallique (5) supportant l'axe de la coupole (6 ). With reference to these drawings, the device comprises a main beam ({) anchored to the ground by means of a yoke (2) and reinforced by a pillar (3) itself fixed to the ground by a yoke (4). These two beams are joined in the upper part by a metal housing (5) supporting the axis of the dome (6).

La partie fixe de la coupole encore appelée préau est composée de quatorze arcs ( 7 ) fixés au sol par des ferrures et réunis en partie haute par deux plaques métalliques (8) elles-mêmes fixées sur l'axe (6 ). Des renforts entre les arcs (9) viennent rigidifier l'ensemble et permettre la fixation de la couverture en plexiglas. The fixed part of the dome also called a courtyard is made up of fourteen arches (7) fixed to the ground by fittings and joined in the upper part by two metal plates (8) themselves fixed on the axis (6). Reinforcements between the arches (9) stiffen the assembly and allow the fixing of the plexiglass cover.

Les secteurs tournants sont composés chacun de cinq arcs (10) fixés aux poutres basses ( ) par des ferrures (4t et réunis par des boîtiers métalliques (43) en partie haute. The rotating sectors are each composed of five arcs (10) fixed to the low beams () by fittings (4t and joined by metal boxes (43) in the upper part.

Des entretoises (9) viennent rigidifier la structure et faciliter également la fixation de la couverture en plexiglas. Spacers (9) stiffen the structure and also facilitate the fixing of the plexiglass cover.

Les poutres tournantes (44) sont équipées chacune de quatre roulettes en téflon (14) et de balais d'étanchéité (15). The rotating beams (44) are each equipped with four Teflon rollers (14) and sealing brushes (15).

L'axe de la coupole est composé d'un support (19 traversé par une tige filetée (4T) sur laquelle vient s'empiler respectivement un joint carbone (48), une rondelle acier (4,), un autre joint carbone (44, un boîtier métallique (43), puis un autre ensemble de joint carbone et rondelle soit (t8) (19) (t#), un autre boîtier métallique (43), etc... The axis of the dome is composed of a support (19 crossed by a threaded rod (4T) on which a carbon gasket (48) is stacked respectively, a steel washer (4,), another carbon gasket (44 , a metal housing (43), then another set of carbon seals and washers (t8) (19) (t #), another metal housing (43), etc ...

On compte ainsi quatre boîtiers de fixation haute des arcs des secteurs mobiles, puis un dernier joint carbone (48), les plaques (8 ) de fixation des arcs fixes, une rondelle (22), un écrou indesserrable (23). L'ensemble est coiffé par une coupole d'étanchéité en acier inoxydable (29 à l'intérieur de laquelle a été soudé un écrou de fixation (23.  There are thus four upper fixing boxes for the arcs of the movable sectors, then a last carbon joint (48), the plates (8) for fixing the fixed arcs, a washer (22), an indessible nut (23). The assembly is capped by a stainless steel sealing dome (29 inside which a fixing nut has been welded (23.

L'axe est verrouillé en sa partie basse par un ensemble rondelle 129 écrou (7 7). The axis is locked in its lower part by a washer 129 nut assembly (7 7).

Le dispositif, selon l'invention, est particulièrement destiné à la couverture de piscine de forme libre. A titre d'exemple non limitatif, pour un bassin (A) de 12 m par 8 m, la coupole a une hauteur de 3,50 met un diamètre de 18 m.  The device according to the invention is particularly intended for the free-form swimming pool cover. By way of nonlimiting example, for a basin (A) of 12 m by 8 m, the dome has a height of 3.50 puts a diameter of 18 m.
