Description

La présente invention concerne le domaine technique du bâchage et du débâchage d'une surface au sens général à l'aide d'un élément de couverture.The present invention relates to the technical field of covering and uncovering of a surface in the general sense using a covering element.

L'objet de l'invention trouve une application dans tous les domaines où une surface délimitant un espace bi ou tridimensionnel doit être recouverte par un élément de couverture ou de protection à caractère enroulable ou empilable comme, par exemple, une bâche, un rideau ou un volet à lames ou à panneaux rigides empilables.The object of the invention finds application in all fields where a surface delimiting a two or three-dimensional space must be covered by a covering or protection element of a rollable or stackable nature such as, for example, a tarpaulin, a curtain or a shutter with stackable slats or rigid panels.

L'objet de l'invention trouve des applications pour permettre de couvrir, par exemple, une piscine ou une surface délimitant le volume d'un véhicule, d'un container ou d'une salle en particulier.The object of the invention finds applications to make it possible to cover, for example, a swimming pool or a surface delimiting the volume of a vehicle, of a container or of a room in particular.

Dans l'état de la technique, il existe de nombreuses solutions permettant la manutention d'un élément de couverture au-dessus d'une surface.In the state of the art, there are many solutions allowing the handling of a roofing element above a surface.

Par exemple, le brevet EP 0 634 981 décrit un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture déplacé à l'aide d'un système de déploiement/rangement comportant un mécanisme d'entraînement en translation d'une ou de plusieurs chaînes rigides au moins en poussée horizontale. Une extrémité de la ou des chaînes est reliée à une poutre de tête sur laquelle est fixée une extrémité de l'élément de couverture dont l'autre extrémité est fixe. Le système de déploiement/rangement comporte également des chariots reliés à l'élément de couverture et assurant une liaison temporaire entre la chaîne et l'élément de couverture. Lors de leurs mouvements, un système agit sur les chariots pour les solidariser avec la chaîne lors du déploiement et pour les désolidariser de la chaîne lors du rangement de l'élément de couverture. La chaîne est ainsi rangée indépendamment de l'élément de couverture et un escamotage complet du dispositif par rapport à la surface est obtenu.For example, the patent EP 0 634 981 describes a device for covering and uncovering a surface using a covering element moved with the aid of a deployment / storage system comprising a drive mechanism in translation of at least one or more rigid chains in horizontal thrust. One end of the chain or chains is connected to a head beam to which is fixed one end of the cover element, the other end of which is fixed. The deployment / storage system also includes carts connected to the cover element and providing a temporary connection between the chain and the cover element. During their movements, a system acts on the carriages to secure them to the chain during deployment and to separate them from the chain when the cover element is stored. The chain is thus stored independently of the cover element and a complete retraction of the device relative to the surface is obtained.

Il est à noter qu'un tel dispositif pour recouvrir et découvrir une surface s'étend en position rangée, principalement à l'intérieur d'une fosse aménagée à une extrémité de la surface à recouvrir. En surplomb de la fosse est aménagé un caisson de protection en façade duquel est aménagé un guichet de passage pour la poutre de tête de l'élément de couverture.It should be noted that such a device for covering and uncovering a surface extends in the stored position, mainly inside a fitted pit. at one end of the surface to be covered. Overhanging the pit is a protective casing on the front of which is fitted a passage window for the head beam of the roofing element.

Si en position de rangement de l'élément de couverture, un tel système de déploiement/ rangement est totalement escamoté par rapport à la surface à couvrir, il doit être constaté que le caisson subsiste en saillie par rapport à la plage périphérique de la surface à recouvrir. La présence d'un tel caisson autour de cette surface créée un obstacle entraînant une gêne pour les déplacements autour de cette surface et une nuisance visuelle plus ou moins importante en fonction de l'environnement dans lequel la surface à couvrir est situé.If in the storage position of the cover element, such a deployment / storage system is completely retracted relative to the surface to be covered, it must be noted that the box remains projecting relative to the peripheral range of the surface to be covered. cover. The presence of such a box around this surface creates an obstacle causing discomfort for movement around this surface and a greater or lesser visual nuisance depending on the environment in which the surface to be covered is located.

Pour tenter d'apporter une solution à ce problème, il est connu une installation de rangement à l'intérieur d'une fosse, d'un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture constitué de panneaux rigides. Une telle installation de rangement comporte un équipage télescopique guidé en déplacement vertical à l'intérieur de la fosse. Cet équipage télescopique supporte le système qui permet de ranger les panneaux en position superposée et de les déployer horizontalement les uns à la suite des autres. Cet équipage télescopique, qui est muni d'un toit de fermeture de la fosse, est déplaçable pour occuper d'une part, une position sortie dans laquelle le toit délimite au-dessus de la fosse, un guichet de passage pour l'élément de couverture en vue de recouvrir et découvrir la surface et d'autre part, une position escamotée dans laquelle le toit s'étend au niveau de la plage périphérique de la surface à recouvrir. L'équipage télescopique est déplacé entre sa position escamotée et sa position sortie, à l'aide d'un système motorisé de déplacement vertical du type vérin hydraulique.In an attempt to provide a solution to this problem, it is known a storage installation inside a pit, a device for covering and uncovering a surface using a covering element made up of panels. rigid. Such a storage installation comprises a telescopic crew guided in vertical movement inside the pit. This telescopic assembly supports the system which makes it possible to store the panels in a superimposed position and to deploy them horizontally one after the other. This telescopic crew, which is provided with a closing roof of the pit, is movable to occupy on the one hand, an extended position in which the roof delimits above the pit, a passage window for the element of cover with a view to covering and uncovering the surface and, on the other hand, a retracted position in which the roof extends at the level of the peripheral range of the surface to be covered. The telescopic assembly is moved between its retracted position and its extended position, using a motorized vertical displacement system of the hydraulic jack type.

Si une telle installation permet de ranger complètement à l'intérieur de la fosse, le dispositif de recouvrement et de découvrement lorsque la surface est découverte, il doit être constaté qu'une telle installation est complexe à mettre en oeuvre et relativement coûteuse. De plus, le système motorisé de déplacement vertical de l'équipage télescopique nécessite la mise en œuvre d'un fluide gras, qui est une source de contamination du milieu environnant. Par ailleurs, une telle installation nécessite l'aménagement d'une fosse de dimensions importantes pour le stockage superposé des panneaux rigides.If such an installation allows the covering and uncovering device to be completely stored inside the pit when the surface is uncovered, it should be noted that such an installation is complex to implement and relatively expensive. In addition, the motorized vertical movement system of the telescopic crew requires the implementation a fatty fluid, which is a source of contamination of the surrounding environment. Furthermore, such an installation requires the provision of a large-sized pit for the superimposed storage of the rigid panels.

Il est également connu par la demande de brevet EP 0 462 609 , un élément de couverture comportant une série de panneaux rigides reliés entre eux par des chaînes et équipés de galets de roulement. Cet élément de couverture est destiné à être rangé à l'intérieur d'une fosse aménagée à l'une des extrémités de l'espace à couvrir. Cette fosse est équipée d'une structure de guidage pour les galets de roulement permettant un rangement des panneaux dont les chaînes coopèrent avec les pignons entraînés en rotation par un moteur.It is also known from the patent application EP 0 462 609 , a covering element comprising a series of rigid panels interconnected by chains and equipped with rollers. This covering element is intended to be stored inside a pit fitted out at one end of the space to be covered. This pit is equipped with a guide structure for the track rollers allowing storage of the panels, the chains of which cooperate with the pinions driven in rotation by a motor.

Indépendamment de la complexité du système pour ranger cet élément de couverture, il doit être noté que le panneau de fermeture de la fosse s'étend en saillie par rapport à la plage périphérique de la surface à recouvrir.Regardless of the complexity of the system for storing this covering element, it should be noted that the pit closure panel protrudes from the peripheral range of the surface to be covered.

Cette installation comporte un équipage télescopique guidé en déplacement vertical à l'intérieur d'une fosse, supportant un système de déploiement/rangement et muni d'un toit de fermeture de la fosse. Cet équipage télescopique est déplaçable pour occuper d'une part, une position escamotée dans laquelle le toit s'étend sensiblement au niveau de la plage périphérique de la surface à couvrir et d'autre part, une position sortie dans laquelle le toit délimite au-dessus de la fosse, un guichet de passage pour l'élément de couverture en vue de recouvrir ou découvrir la surface. Cette installation comporte également un système motorisé de déplacement vertical de l'équipage télescopique entre sa position escamotée et sa position sortie. Ce système motorisé comporte deux chaînes rigides au moins en poussée vertical coopérant avec un pignon d'un motoréducteur présentant un axe s'étendant horizontalement. Chaque chaîne comporte une extrémité fixée à un coulisseau coopérant avec un système de guidage vertical.It is also known by the patent FR 2997976 , an installation for storing a device for covering and uncovering a surface, using a covering element. This installation comprises a telescopic crew guided in vertical movement inside a pit, supporting a deployment / storage system and provided with a closing roof of the pit. This telescopic unit can be moved to occupy, on the one hand, a retracted position in which the roof extends substantially at the level of the peripheral range of the surface to be covered and, on the other hand, an extended position in which the roof delimits at the- above the pit, a passage window for the cover element in order to cover or uncover the surface. This installation also includes a motorized system for vertical displacement of the telescopic assembly between its retracted position and its extended position. This motorized system comprises two rigid chains at least in vertical thrust cooperating with a pinion of a geared motor having an axis extending horizontally. Each chain has one end attached to a slide cooperating with a vertical guide system.

Si une telle installation donne satisfaction en pratique, cette installation présente un encombrement relativement important et s'avère en pratique, coûteuse et difficile à mettre en œuvre. La demande de brevet WO 2012/156622 décrit une installation pour ranger dans un logement, une couverture d'obturation formée de panneaux aptes à passer d'une configuration déployée les uns à côté des autres, à une configuration empilée les uns sur les autres et comprimant des moyens élastiquement déformables montés dans le logement. La demande de brevet EP 0 462 609 décrit un système de déplacement d'une couverture formée d'une série de caissons équipés à leurs extrémités de deux chaînes latérales coopérant avec un arbre motorisé assurant le passage de la couverture d'une configuration déployée à une configuration rangée. Les chaînes sont pourvues de galets adaptés pour coopérer dans des rails de rangement aménagés dans une chambre de stockage pour la couverture.If such an installation is satisfactory in practice, this installation has a relatively large footprint and is in practice expensive and difficult to implement. The patent application WO 2012/156622 describes an installation for storing in a housing, a blanking cover formed of panels able to pass from a configuration deployed one beside the other, to a configuration stacked on top of each other and compressing elastically deformable means mounted in the housing. The patent application EP 0 462 609 describes a system for moving a cover formed by a series of boxes equipped at their ends with two side chains cooperating with a motorized shaft ensuring the passage of the cover from a deployed configuration to a stored configuration. The chains are provided with rollers adapted to cooperate in storage rails arranged in a storage chamber for the cover.

Tel que cela ressort plus précisément des Fig. 1 à Fig. 7 , l'objet de l'invention concerne une installation 1 adaptée pour ranger à l'intérieur d'une chambre 2, un dispositif 3 pour recouvrir et découvrir une surface 4 au sens général, tel une piscine, un spa, une aire de jeux ou un container par exemple. La chambre 2 est aménagée le long d'un bord latéral 41 de la surface 4, à proximité ou à une distance relativement proche du bord latéral 41 de la surface 4. Par convention, il est considéré que la surface 4 à recouvrir comporte deux bords latéraux opposés 41 et deux bords longitudinaux opposés 42 , délimités par une plage périphérique 5 réalisée en tous matériaux appropriés. La chambre 2 est délimitée par une fosse enterrée ou par un coffre réalisé hors sol.As it emerges more precisely from Fig. 1 to Fig. 7 , the object of the invention relates to an installation 1 adapted to store inside a room 2 , a device 3 for covering and uncovering a surface 4 in the general sense, such as a swimming pool, a spa, a playground or a container for example. The chamber 2 is arranged along a side edge 4 1 of the surface 4 , near or at a relatively close distance from the side edge 4 1 of the surface 4 . By convention, it is considered that the surface 4 to be covered comprises two opposite side edges 4 1 and two opposite longitudinal edges 4 2 , delimited by a peripheral area 5 made of any suitable materials. Bedroom 2 is delimited by a buried pit or by a safe made above ground.

Le dispositif 3 comporte un élément de couverture 6 simplement schématisé à la Fig. 3 et apte à être déplacé à l'aide d'un système de déploiement/rangement 8 qui sera décrit plus en détail dans la suite de la description. Tel que cela ressort plus précisément des Fig. 1 à 3 , l'élément de couverture 6 est destiné à être déplacé par le système 8 selon un sens de déploiement f1 pour qu'il occupe la position de recouvrement total de la surface 4 et selon un sens contraire de rangement f2 afin que l'élément de couverture 6 puisse être rangé à l'intérieur de la chambre 2 de manière à découvrir la surface 4. L'élément de couverture 6 peut être réalisé par une bâche souple ou par des panneaux rigides articulés.The device 3 comprises a cover element 6 simply shown diagrammatically on Fig. 3 and able to be moved using a deployment / storage system 8 which will be described in more detail in the remainder of the description. As it emerges more precisely from Fig. 1 to 3 , the cover element 6 is intended to be moved by the system 8 in a direction of deployment f 1 so that it occupies the position of total covering of the surface 4 and in a contrary direction of storage f 2 so that the cover element 6 can be stored inside the chamber 2 so as to uncover the surface 4. The cover element 6 can be produced by a flexible tarpaulin or by hinged rigid panels.

Dans l'exemple de réalisation illustré sur les dessins, le système de déplacement et rangement 8 correspond au système décrit par le brevet EP 0 634 981 .In the exemplary embodiment illustrated in the drawings, the movement and storage system 8 corresponds to the system described by the patent. EP 0 634 981 .

Le système de déploiement/rangement 8 comporte un mécanisme 10 d'entraînement en translation pour au moins une et dans l'exemple illustré, deux chaînes 12 présentant la propriété de devenir rigide au moins en poussée selon une direction horizontale. Chaque chaîne 12 est constituée par une série de maillons articulés entre eux autour d'axes 13 et pourvus d'épaulements 14 destinés à venir s'appuyer les uns contre les autres au fur et à mesure lors de la sortie des chaînes 12 de la chambre 2. Ainsi, les épaulements 14 sont adaptés pour autoriser un pivotement relatif des maillons selon un sens donné et pour interdire un tel pivotement dans le sens contraire.The deployment / storage system 8 comprises a translation drive mechanism 10 for at least one and in the example illustrated, two chains 12 having the property of becoming rigid at least in thrust in a horizontal direction. Each chain 12 is constituted by a series of links articulated between them around axes 13 and provided with shoulders 14 intended to come to rest against each other as and when the chains 12 come out of the chamber. 2 . Thus, the shoulders 14 are adapted to allow relative pivoting of the links in a given direction and to prevent such pivoting in the opposite direction.

Les chaînes 12 sont adaptées pour se déplacer sur des voies de déplacement s'établissant sur les parties de la plage périphérique 5 situées le long des bords longitudinaux 42 de la surface 4. Ces chaînes 12 sont équipées de préférence d'organes de roulement pour faciliter leurs mouvements de translation sur la plage périphérique de la surface 4.The channels 12 are adapted to move on the travel routes is laying on parts of the peripheral flange 5 located along the longitudinal edges 4 2 of the surface 4. These chains 12 are preferably equipped with rolling members to facilitate their translational movements on the peripheral range of the surface 4 .

Le mécanisme d'entraînement 10 comporte également pour chaque chaîne 12, un pignon 15 entraîné en rotation ( Fig. 4 ). Avantageusement, les deux pignons 15 sont reliés entre eux par un arbre de liaison 16 entraîné en rotation par un moteur non représenté dont le fonctionnement est piloté pour permettre la rotation des pignons 15 selon l'un ou l'autre sens de rotation afin d'assurer le déplacement des chaînes 12 selon le sens de déploiement f1 ou le sens de rangement f2 . L'une des extrémités des chaînes 12 est reliée à une poutre de tête 18 sur laquelle est fixé l'élément de couverture 6 par l'une de ses extrémités, l'extrémité opposée de l'élément de couverture 6 étant fixé à l'intérieur de la chambre 2. La poutre de tête 18 est donc apte à se déplacer entre la chambre 2 et le bord latéral dépourvu de la chambre 2. De préférence, la poutre de tête 18 est équipée à chaque extrémité d'un organe de roulement destiné à rouler sur les voies de déplacement s'établissant sur les parties de la plage périphérique 5 situées le long des bords longitudinaux 42 de la surface 4.The drive mechanism 10 also comprises for each chain 12 , a pinion 15 driven in rotation ( Fig. 4 ). Advantageously, the two pinions 15 are interconnected by a connecting shaft 16 driven in rotation by a motor, not shown, the operation of which is controlled to allow the rotation of the pinions 15 in one or the other direction of rotation in order to ensure the movement of the chains 12 according to the deployment direction f 1 or the storage direction f 2 . One end of the chains 12 is connected to a head beam 18 to which the cover element 6 is fixed by one of its ends, the opposite end of the cover element 6 being fixed to the interior of bedroom 2 . The head beam 18 is therefore able to move between the chamber 2 and the side edge without the chamber 2 . Preferably, the head beam 18 is equipped at each end with a rolling member intended to roll on the travel tracks being established on the parts of the peripheral range 5 located along the longitudinal edges 4 2 of the surface 4 .

Les autres extrémités des chaînes qui ne sont pas reliées à la poutre de tête 18 sont destinées à être récupérées par un dispositif de récupération aménagé à partir de la chambre 2 et de tous types connus en soi.The other ends of the chains which are not connected to the head beam 18 are intended to be recovered by a recovery device arranged from the chamber 2 and of all types known per se.

Le système de déploiement et de rangement 8 comporte également une série de chariots 22 assurant une liaison temporaire entre l'élément de couverture 6 et chaque chaîne 12. L'élément de couverture 6 est fixé sur des traverses ou arceaux 24 destinés à maintenir en place l'élément de couverture 6 au-dessus de la surface 4. Chaque arceau 24 est fixé par ses extrémités, à deux chariots 22 dont l'un coopère avec une chaîne 12 et l'autre coopère avec l'autre chaîne 12.The deployment and storage system 8 also comprises a series of carriages 22 providing a temporary connection between the cover element 6 and each chain 12 . The covering element 6 is fixed to crossbars or hoops 24 intended to hold the covering element 6 in place above the surface 4 . Each hoop 24 is fixed by its ends to two carriages 22 , one of which cooperates with a chain 12 and the other cooperates with the other chain 12 .

Le système de déploiement/rangement 8 comporte également un système 26 agissant sur les chariots 22 pour les solidariser avec la chaîne 12 lors du déploiement de l'élément de couverture 6 et pour les désolidariser de la chaîne 12 lors du rangement de l'élément de couverture 6. Il est à noter que l'élément de couverture 6 coopère lors de son déploiement et rangement avec un tambour 27 porté par l'arbre de liaison 15.The deployment / storage system 8 also comprises a system 26 acting on the carriages 22 to secure them with the chain 12 during the deployment of the cover element 6 and to separate them from the chain 12 when the storage element is stored. cover 6 . It should be noted that the cover element 6 cooperates during its deployment and storage with a drum 27 carried by the connecting shaft 15 .

Par exemple, le système 26 comporte comme expliqué dans le brevet EP 0 634 981 , un doigt porté par chaque chariot 22 et adapté pour venir s'engager entre deux axes d'articulation 13 de manière à constituer un moyen de liaison temporaire entre la chaîne 12 et les traverses 24. Le système 26 comporte également pour chaque chaîne 12, un rail 29 s'étendant au niveau de la chambre 2 et assurant la séparation de la chaîne 12 par rapport aux chariots 22 lors du déplacement de la chaîne 12 selon le sens de rangement. Lors de cette phase, les chariots 22 qui sont désolidarisés de la chaîne 12 sont stockés sur la partie arrière du rail 29 tandis que les chaînes 12 rentrent dans le système de rangement prévu à cet effet.For example, the system 26 behaves as explained in the patent EP 0 634 981 , a finger carried by each carriage 22 and adapted to engage between two articulation pins 13 so as to constitute a temporary connection means between the chain 12 and the cross members 24 . The system 26 also comprises for each chain 12 , a rail 29 extending at the level of the chamber 2 and ensuring the separation of the chain 12 from the carriages 22 during the movement of the chain 12 in the direction of storage. During this phase, the carriages 22 which are disconnected from the chain 12 are stored on the rear part of the rail 29 while the chains 12 enter the storage system provided for this purpose.

La description qui précède concerne un système de déploiement/rangement 8 mettant en œuvre une bâche souple 6 entraînée en déplacement à l'aide de chaînes rigides 12, mais il est clair que l'installation de rangement 1 conforme à l'invention peut être mise en œuvre pour un dispositif de déploiement/rangement 8 différent dont l'élément de couverture et/ou le système de déplacement sont différents de ceux décrits.The above description relates to a deployment / storage system 8 implementing a flexible tarpaulin 6 driven in movement by means of rigid chains 12 , but it is clear that the storage installation 1 according to the invention can be used. implemented for a different deployment / storage device 8 of which the cover element and / or the movement system are different from those described.

L'installation de rangement 1 comporte également un équipage télescopique 30 guidé en déplacement vertical à l'intérieur de la chambre 2, à l'aide d'un système de guidage 31. Il doit être compris que l'équipage télescopique 30 supporte en partie le système de déploiement/rangement 8 et en particulier l'arbre de liaison 16 et les pignons 15 d'entrainement des chaînes.The storage installation 1 also comprises a telescopic unit 30 guided in vertical movement inside the chamber 2 , using a guide system 31 . It should be understood that the telescopic crew 30 partly supports the deployment / storage system 8 and in particular the connecting shaft 16 and the chain drive sprockets 15 .

Cet équipage télescopique 30 qui est équipé d'un toit 33 de fermeture de la chambre 2, est déplaçable verticalement pour occuper d'une part, une position escamotée dans laquelle le toit 33 s'étend sensiblement au niveau de la plage périphérique de la surface 4 ( Fig. 1 ) et d'autre part, une position sortie dans laquelle le toit 33 délimite au-dessus de la chambre 2, un guichet de passage 35 pour l'élément de couverture 6 ( Fig. 2 et 3 ). Ainsi, en position sortie du de l'équipage télescopique 30, le toit 33 (qui est représenté partiellement à la Fig. 1 ) s'élève en saillie par rapport à la plage périphérique 5 de la surface 4, comme illustré à la Fig. 7 .This telescopic crew 30 which is equipped with a roof 33 for closing the chamber 2 , can be moved vertically to occupy, on the one hand, a retracted position in which the roof 33 extends substantially at the level of the peripheral range of the surface 4 ( Fig. 1 ) and on the other hand, an extended position in which the roof 33 defines above the chamber 2 , a passage window 35 for the cover element 6 ( Fig. 2 and 3 ). Thus, in the extended position of the telescopic crew 30, the roof 33 (which is shown partially in the Fig. 1 ) protrudes from the peripheral range 5 of the surface 4 , as shown in Fig. 7 .

Il doit être compris que lorsque le système de déploiement/rangement 8 est rangé à l'intérieur de la chambre 2, le toit 33 ferme la chambre 2 dans la continuité de la plage périphérique 5 de la surface 4. Le toit de fermeture 33 est revêtu d'un matériau de préférence, mais non exclusivement, identique à celui utilisé comme revêtement de la plage périphérique de la surface 4. Lorsque l'élément de couverture 6 recouvre la surface 4, l'équipage télescopique 30 s'étend en saillie par rapport au niveau de la surface 4 pour permettre les opérations de déploiement et de rangement de la poutre de tête 18, de l'élément de couverture 6 et des chaînes 12.It should be understood that when the deployment / storage system 8 is stored inside the chamber 2 , the roof 33 closes the chamber 2 in the continuity of the peripheral range 5 of the surface 4 . The closing roof 33 is coated with a material preferably, but not exclusively, identical to that used as the coating of the peripheral range of the surface 4 . When the cover element 6 covers the surface 4 , the telescopic assembly 30 protrudes from the level of the surface 4 to allow the operations of deployment and storage of the head beam 18 , of the element. cover 6 and chains 12 .

Selon la variante de réalisation illustrée à la Fig. 7 , le toit 33 se présente sous la forme d'une partie horizontale monobloc. Selon une variante préférée de réalisation, le toit 33 comporte une partie avant s'étendant sensiblement horizontalement et une partie arrière articulée à la partie avant sur le côté opposé de celui délimitant le guichet de passage 35.According to the variant embodiment illustrated in Fig. 7 , the roof 33 is in the form of a one-piece horizontal part. According to a preferred variant embodiment, the roof 33 comprises a front part extending substantially horizontally and a rear part articulated to the front part on the opposite side from that delimiting the passage window 35 .

L'installation de rangement 1 selon l'invention comporte également un système motorisé 50 de déplacement vertical de l'équipage télescopique 30 entre sa position escamotée et sa position sortie. Conformément à l'invention, le système motorisé 50 comporte un mécanisme 51 de soulèvement automatique de l'équipage télescopique 30, exerçant en permanence sur l'équipage télescopique, un effort de levage pour assurer le déplacement de cet équipage télescopique entre sa position escamotée et sa position sortie. En d'autres termes, ce mécanisme de soulèvement 51 exerce en permanence un effort vertical pour soulever l'équipage télescopique 30.The storage installation 1 according to the invention also comprises a motorized system 50 for vertical displacement of the telescopic assembly 30 between its retracted position and its extended position. In accordance with the invention, the motorized system 50 comprises a mechanism 51 for automatically lifting the telescopic assembly 30 , continuously exerting on the telescopic assembly, a lifting force to ensure the movement of this telescopic assembly between its retracted position and its extended position. In other words, this lifting mechanism 51 constantly exerts a vertical force to lift the telescopic assembly 30 .

Dans l'exemple de réalisation illustré sur les dessins, le mécanisme de soulèvement 51 comporte au moins un et dans l'exemple illustré aux Fig. 1 à 6 , deux ressorts de compression 52 montés entre la chambre 2 et l'équipage télescopique 30. Tel que cela ressort plus précisément des Fig. 6 et 6A , chaque ressort de compression 52 est monté à l'intérieur d'un cylindre 53 pourvu d'un fond 54 monté solidaire de l'équipage télescopique 30. Le ressort de compression 52 prend appui, d'un côté, sur le fond 54 et sur son côté opposé, sur une semelle 55 fixée à l'extrémité supérieure d'un tube 58 s'élevant verticalement à l'intérieur de la chambre 2. Chaque tube 58 est fixé par tous moyens appropriés sur le fond de la chambre 2.In the exemplary embodiment illustrated in the drawings, the lifting mechanism 51 comprises at least one and in the example illustrated in Fig. 1 to 6 , two compression springs 52 mounted between the chamber 2 and the telescopic assembly 30 . As it emerges more precisely from Fig. 6 and 6A , each compression spring 52 is mounted inside a cylinder 53 provided with a bottom 54 mounted integral with the telescopic assembly 30. The compression spring 52 is supported, on one side, on the bottom 54 and on its opposite side, on a sole 55 fixed to the upper end of a tube 58 rising vertically inside the chamber 2 . Each tube 58 is fixed by any suitable means on the bottom of the chamber 2 .

Chaque fond 54 du cylindre 52 est fixé à une poutre support 60 faisant partie de l'équipage télescopique 30. Avantageusement, les fonds 54 des cylindres 53 sont fixés dans les régions d'extrémité de la poutre support 60. Chaque ressort de compression 52 est apte à ainsi occuper d'une part, une position comprimée ( Fig. 6A ) pour laquelle l'équipage télescopique 30 occupe une position escamotée et d'autre part, une position dite de détente ( Fig. 6 ) pour laquelle l'équipage télescopique 30 occupe sa position sortie. Comme cela sera expliqué dans la suite de la description, les ressorts de compression 52 sont dimensionnés de manière à pouvoir soulever l'équipage télescopique pour le faire passer de sa position escamotée à sa position sortie et pour supporter la charge de l'équipage télescopique 30 occupant sa position sortie.Each bottom 54 of cylinder 52 is fixed to a support beam 60 forming part of the telescopic assembly 30 . Advantageously, the bottoms 54 of the cylinders 53 are fixed in the end regions of the support beam 60. Each compression spring 52 is thus able to occupy, on the one hand, a compressed position ( Fig. 6A ) for which the telescopic assembly 30 occupies a retracted position and on the other hand, a so-called relaxed position ( Fig. 6 ) for which the telescopic assembly 30 occupies its extended position. As will be explained in the rest of the description, the compression springs 52 are dimensioned so as to be able to lift the telescopic assembly to make it pass from its retracted position to its extended position and to support the load of the telescopic assembly 30. occupying its extended position.

Dans l'exemple de réalisation illustré aux Fig. 1 à 6 , le mécanisme de soulèvement 51 comporte deux ressorts de compression 52. Dans l'exemple de réalisation illustré à la Fig. 7 , le mécanisme de soulèvement 51 comporte quatre ressorts de compression 52 permettant de soulever un toit 33 plus lourd que celui soulevé dans l'exemple illustré aux Fig. 1 à 6 .In the embodiment illustrated in Fig. 1 to 6 , the lifting mechanism 51 comprises two compression springs 52 . In the exemplary embodiment illustrated in Fig. 7 , the lifting mechanism 51 comprises four compression springs 52 making it possible to lift a roof 33 heavier than that raised in the example illustrated in Fig. 1 to 6 .

Selon une autre caractéristique de l'invention, le système motorisé 50 comporte un système commandé 61 permettant de contrôler le mécanisme de soulèvement 51. Ce système commandé 61 permet de contrôler l'effort de soulèvement appliqué à l'équipage télescopique, par le mécanisme de soulèvement 51 de manière à permettre de positionner l'équipage télescopique soit dans sa position escamotée, soit dans sa position sortie.According to another characteristic of the invention, the motorized system 50 comprises a controlled system 61 making it possible to control the lifting mechanism 51 . This controlled system 61 makes it possible to control the lifting force applied to the telescopic assembly, by the lifting mechanism. lifting 51 so as to allow the telescopic assembly to be positioned either in its retracted position or in its extended position.

Le système commandé 61 de contrôle du mécanisme de soulèvement 51 comporte au moins un et dans l'exemple illustré, un treuil motorisé 63 entraînant en rotation un tambour 64 supporté selon un exemple préféré de réalisation par la poutre support 60. Le treuil 63 comporte ainsi un organe moteur 65 de préférence électrique, supporté par l'équipage télescopique et en particulier par la poutre support 60. L'organe moteur 65 est monté pour entrainer la rotation du tambour 64 dans l'un et/ou l'autre de ces sens de rotation.The controlled system 61 for controlling the lifting mechanism 51 comprises at least one, and in the example illustrated, a motorized winch 63 driving in rotation a drum 64 supported according to a preferred example of embodiment by the support beam 60 . The winch 63 thus comprises a motor member 65 , preferably electric, supported by the telescopic assembly and in particular by the support beam 60 . The motor member 65 is mounted to cause the rotation of the drum 64 in one and / or the other of these directions of rotation.

Le tambour 64 assure l'enroulement et le déroulement d'au moins une et dans l'exemple illustré, de deux élingues 66 agissant sur l'équipage télescopique 30 afin de contrôler l'effort de soulèvement appliqué par ledit mécanisme de soulèvement 51. Les élingues 66 sont montées entre l'équipage télescopique 30 et un ancrage 67. Chaque élingue 66 comporte ainsi une extrémité fixée au tambour 64 tandis que son extrémité opposée est fixée à l'ancrage 67 qui est réalisé de toute matière appropriée et en tous endroits adaptés pour contrôler l'effort de soulèvement appliqué par le mécanisme de soulèvement 51. Chaque élingue 66 est une corde ou une chaîne. Avantageusement, les deux élingues 66 sont enroulées à proximité de chacune des extrémités du tambour 64.The drum 64 ensures the winding and unwinding of at least one and in the example illustrated, of two slings 66 acting on the telescopic assembly 30 in order to control the lifting force applied by said lifting mechanism 51 . The slings 66 are mounted between the telescopic crew 30 and an anchor 67 . Each sling 66 thus has one end fixed to the drum 64 while its opposite end is fixed to the anchor 67 which is made of any suitable material and in all places suitable for controlling the lifting force applied by the lifting mechanism 51 . Each sling 66 is a rope or chain. Advantageously, the two slings 66 are wound near each of the ends of the drum 64 .

Selon un exemple avantageux de réalisation, chaque élingue 66 coopère avec au moins une poulie de renvoi 69 permettant de démultiplier l'effort antagonisme à l'effort de soulèvement exercé par le mécanisme de soulèvement 51. Dans les exemples illustrés sur les dessins, les poulies de renvoi 69 sont fixées sur le fond de la chambre 2, de sorte que chaque élingue 66 comporte un premier brin s'étendant sensiblement verticalement entre le tambour et la poulie de renvoi voisine et un deuxième brin s'étendant sensiblement verticalement entre la poulie de renvoi voisine de l'ancrage 67.According to an advantageous exemplary embodiment, each sling 66 cooperates with at least one deflection pulley 69 making it possible to multiply the force antagonistic to the lifting force exerted by the lifting mechanism 51 . In the examples illustrated in the drawings, the deflection pulleys 69 are fixed to the bottom of the chamber 2 , so that each sling 66 has a first strand extending substantially vertically between the drum and the neighboring deflection pulley and a second strand extending substantially vertically between the return pulley adjacent to the anchor 67 .

Selon un exemple préféré de réalisation illustré sur les Fig. 1 à 5 , l'ancrage 67 est situé sur la poutre support 60 alors que les élingues passent autour d'une poulie de renvoi en étant déplacées par le treuil 63 monté sur la poutre support 60. Bien entendu, l'ancrage 67 peut être aménagé au niveau d'une paroi de la chambre 2 comme par exemple sur une paroi verticale délimitant la chambre 2 comme dans l'exemple illustré à la figure 7 . De même dans les exemples illustrés, le treuil motorisé 63 est monté sur l'équipage télescopique 30. Il est clair qu'il peut être envisagé de monter le treuil motorisé 63 à l'intérieur de la chambre 2 tandis que l'ancrage 67 de l'élingue 66 est réalisé sur l'équipage télescopique 30 et en particulier, sur la poutre support 60.According to a preferred embodiment illustrated on Fig. 1 to 5 , the anchor 67 is located on the support beam 60 while the slings pass around a return pulley while being moved by the winch 63 mounted on the support beam 60 . Of course, the anchor 67 can be arranged at a wall of the chamber 2 such as for example on a vertical wall delimiting the chamber 2 as in the example illustrated in figure 7 . Likewise in the examples illustrated, the motorized winch 63 is mounted on the telescopic assembly 30 . It is clear that it can be envisaged to mount the motorized winch 63 inside the chamber 2 while the anchoring 67 of the sling 66 is made on the telescopic assembly 30 and in particular, on the support beam. 60 .

Il est à noter que dans l'exemple de réalisation illustré aux Fig. 1 à 6 , chaque élingue 66 coopère avec une unique poulie de renvoi 69 tandis que dans l'exemple de réalisation illustré à la Fig. 7 , chaque élingue 66 est guidée par deux poulies de renvoi 69 fixées sur le fond de la chambre en étant écartées pour être positionnées sensiblement à l'aplomb respectivement du tambour 64 et de la paroi verticale de la chambre 2.It should be noted that in the embodiment illustrated in Fig. 1 to 6 , each sling 66 cooperates with a single return pulley 69 while in the embodiment illustrated in Fig. 7 , each sling 66 is guided by two return pulleys 69 fixed to the bottom of the chamber, being spaced apart to be positioned substantially directly above the drum 64 and the vertical wall of the chamber 2, respectively .

Le fonctionnement du treuil motorisé 63 est piloté par une unité de commande non représentée mais connue en soi. Cette unité de commande permet de piloter le système 61 de contrôle du mécanisme de soulèvement 51 permettant de piloter le fonctionnement du treuil motorisé 63 afin de faire passer automatiquement l'équipage télescopique 30 de sa position escamotée à sa position sortie, et réciproquement. Il doit être compris que cette unité de commande permet de piloter la rotation du treuil entraînant l'enroulement ou le déroulement des élingues 66 autour du tambour 64 ayant pour effet de régler la position verticale de l'équipage mobile 30. Ainsi l'enroulement des élingues 66 autour du tambour 64 entraîne un abaissement de l'équipage télescopique 30 tandis que le déroulement des élingues conduit au soulèvement de l'équipage télescopique 30.The operation of the motorized winch 63 is controlled by a control unit not shown but known per se. This control unit makes it possible to control the system 61 for controlling the lifting mechanism 51 making it possible to control the operation of the motorized winch 63 in order to automatically switch the telescopic assembly 30 from its retracted position to its extended position, and vice versa. It should be understood that this control unit makes it possible to control the rotation of the winch causing the winding or unwinding of the slings 66 around the drum 64 having the effect of adjusting the vertical position of the mobile assembly 30 . Thus the winding of the slings 66 around the drum 64 causes the telescopic assembly 30 to be lowered while the unwinding of the slings leads to the lifting of the telescopic assembly 30 .

Selon une variante préférée de réalisation, l'installation comporte un dispositif de détection des positions escamotées et de sortie de l'équipage mobile 30. Ce dispositif de détection est relié à l'unité de commande pour permettre de piloter le fonctionnement ou l'arrêt du treuil motorisé 63 lorsque l'équipage mobile 30 occupe soit sa position escamotée, soit sa position de sortie. Bien entendu un tel dispositif de détection peut être réalisé de toute manière appropriée comme par exemple par des capteurs de position.According to a preferred variant embodiment, the installation comprises a device for detecting the retracted and exit positions of the moving assembly 30 . This detection device is connected to the control unit to enable the operation or stopping of the motorized winch 63 to be controlled. when the mobile unit 30 occupies either its retracted position or its exit position. Of course, such a detection device can be produced in any suitable manner such as for example by position sensors.

Selon une variante préférée de réalisation, l'installation comporte au moins un système 31 de guidage vertical de l'équipage télescopique 30. Dans l'exemple illustré, l'installation comporte deux systèmes 31 de guidage vertical de l'équipage télescopique 30, installés aux extrémités de la poutre support 60. Chaque système de guidage 71 comporte au moins un et dans l'exemple illustré deux coulisseaux 72 supportés par un profil 73 en forme de « U » qui est fixé à la poutre support 60. Les deux coulisseaux 72 d'un système de guidage coopèrent avec une coulisse 75 fixée sur une paroi de la chambre 2.According to a preferred variant embodiment, the installation comprises at least one system 31 for vertical guidance of the telescopic assembly 30 . In the example illustrated, the installation comprises two systems 31 for vertical guidance of the telescopic assembly 30 , installed at the ends of the support beam 60 . Each guide system 71 comprises at least one and in the example illustrated two slides 72 supported by a profile 73 in the shape of a "U" which is fixed to the support beam 60. The two slides 72 of a guide system cooperate with a slide 75 fixed to a wall of the chamber 2 .

Il ressort de la description qui précède que l'installation selon l'invention est de mise en œuvre simple et peu coûteuse. Son fonctionnement est simplifié puisqu'il suffit de commander la rotation du treuil 63 pour contrôler l'effort de levage exercé en permanence par les ressorts 52 sur l'équipage mobile 30. En effet, les ressorts de compression 52 en position comprimée constituent une réserve d'énergie progressive, cette compression des ressorts étant assurée par l'enroulement des élingues par le treuil électrique. La récupération de l'énergie stockée se fait par l'opération inverse visant le déroulement des élingues permettant de libérer de façon maîtriser le déplacement de l'équipage télescopique 30. Il est à noter que le poids total de l'équipage télescopique 30 varie en fonction de l'état d'enroulement de l'élément de couverture 6. En particulier, ce poids diminue alors que la réserve d'énergie des ressorts diminue de sorte que le dimensionnement du mécanisme de soulèvement est limité. L'installation selon l'invention s'avère très simple à fabriquer et à installer tout en présentant un coût modique. Enfin, cette installation ne comporte pas de mécanisme faisant appel à des fluides gras qui sont toujours une source de pollution.It emerges from the above description that the installation according to the invention is simple and inexpensive to implement. Its operation is simplified since it suffices to control the rotation of the winch 63 to control the lifting force permanently exerted by the springs 52 on the mobile assembly 30 . In fact, the compression springs 52 in the compressed position constitute a progressive reserve of energy, this compression of the springs being ensured by the winding of the slings by the electric winch. The stored energy is recovered by the reverse operation aimed at unwinding the slings making it possible to release in a controlled manner the movement of the telescopic crew 30 . It should be noted that the total weight of the telescopic assembly 30 varies depending on the state of winding of the cover element 6 . In particular, this weight decreases as the energy reserve of the springs decreases so that the dimensioning of the lifting mechanism is limited. The installation according to the invention turns out to be very simple to manufacture and to install while having a low cost. Finally, this installation does not include a mechanism using fatty fluids which are always a source of pollution.
