Abstract

The device has a central shaft provided with one wheel at each end. A mandrel (7) rolls and unrolls a closing unit (2) e.g. tarpaulin, and is driven in rotation by a driving unit. The mandrel extends around the shaft between the wheels, and is guided in rotation by a guiding unit mounted on the shaft. A displacement unit (14) partly supports the driving unit and has a gripping handle (15) for exerting a force on the device. The wheels are separated from one another with measurement greater than width of a surface to be covered. The handle exerts the force on the device in its displacement direction. An independent claim is also included for a method for covering and uncovering a surface.

Description

La présente invention concerne le domaine technique des dispositifs de manutention d'un élément de couverture enroulable au-dessus d'une surface au sens général.The present invention relates to the technical field of handling devices of a roll-over roof element over a surface in the general sense.

L'objet de l'invention trouve une application dans tous les domaines où une surface délimitant un espace bi ou tri-dimensionnel doit être recouvert par un élément d'occultation ou de protection à caractère enroulable comme par exemple, une bâche, un rideau ou un volet à lames.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 curtain-type concealment or protection element such as, for example, a tarpaulin, a curtain or a shutter with blades.

L'invention est adaptée 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 invention is adapted to cover for example a pool or a surface defining the volume of a vehicle, a container or a particular room.

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

Par exemple, le brevet FR 2 789 425 décrit un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture enroulable, réalisé sous la forme d'un portique supporté à chaque extrémité par des rails de guidage aménagés le long de la surface à couvrir. Un tel portique comporte un mandrin d'enroulement pour l'élément de couverture, s'étendant transversalement au-dessus de la surface à recouvrir. Un tel dispositif comporte également des moyens moteurs assurant simultanément un mouvement de rotation du mandrin d'enroulement et un mouvement de translation du portique le long des rails de guidage.For example, the patent FR 2 789 425 discloses a device for covering and uncovering a surface by means of a roll-up roofing element, in the form of a gantry supported at each end by guide rails arranged along the surface to be covered. Such a gantry comprises a winding mandrel for the cover element, extending transversely above the surface to be covered. Such a device also comprises motor means simultaneously providing a rotational movement of the winding mandrel and a translational movement of the gantry along the guide rails.

Un inconvénient de cette solution réside dans la nécessité d'équiper les bords de l'espace à couvrir, par des rails de guidage pour le portique, ce qui entrave l'accès à l'espace à couvrir. De plus, un tel dispositif de manutention nécessite de mettre en oeuvre des moyens de synchronisation entre les moyens d'entraînement en rotation du mandrin et les moyens de déplacement du portique de sorte qu'un tel dispositif présente un coût élevé et une complexité de mise en oeuvre.A disadvantage of this solution lies in the need to equip the edges of the space to be covered by guide rails for the gantry, which hampers access to the space to be covered. In addition, such a handling device requires the use of synchronization means between the mandrel rotating drive means and the gantry displacement means so that such a device has a high cost and complexity of implementation. implemented.

Par ailleurs, il est également connu par le document DE 2 257 231 , un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture enroulable. Un tel dispositif se présente sous la forme d'un portique comportant un arbre central équipé à chaque extrémité d'une roue faisant partie d'un chariot distant l'un de l'autre d'une mesure supérieure à la largeur de la surface à recouvrir. Un tel dispositif comporte également un mandrin d'enroulement et de déroulement pour l'élément de couverture supporté par les deux chariots. Un tel dispositif comporte également des moyens d'entraînement d'une part des chariots et d'autre part du mandrin d'enroulement de l'élément de couverture.Moreover, he is also known by the document DE 2 257 231 , a device for covering and uncovering a surface by means of a roll-up cover element. Such a device is in the form of a gantry comprising a central shaft equipped at each end with a wheel forming part of a remote carriage from each other a measurement greater than the width of the surface to be covered. Such a device also comprises a winding mandrel and unwinding for the cover element supported by the two carriages. Such a device also comprises means for driving on the one hand the carriages and on the other hand the winding mandrel of the covering element.

Un tel dispositif ne permet pas d'enrouler l'élément de couverture indépendamment du déplacement du portique. D'une manière générale, il doit être considéré qu'un tel dispositif qui présente une conception complexe, ne permet pas d'une manière simple, de découvrir ou de recouvrir une surface à l'aide d'un élément de couverture.Such a device does not allow to wind the cover element independently of the movement of the gantry. In general, it should be considered that such a device which has a complex design, does not allow in a simple way, to discover or cover a surface with a cover element.

L'analyse de l'état de la technique conduit à constater qu'il apparaît le besoin de disposer d'un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture enroulable, ne nécessitant pas d'aménagement sur les bords de la surface à couvrir et présentant une facilité de mise en oeuvre ainsi qu'un coût de fabrication réduit.The analysis of the state of the art leads to the conclusion that there is a need for a device for covering and uncovering a surface using a roll-up roofing element, which does not require development on the edges of the surface to be covered and having an ease of implementation and a reduced manufacturing cost.

La présente invention vise donc à atteindre un tel objectif en proposant un dispositif pour recouvrir et découvrir une surface à l'aide d'un élément de couverture enroulable, le dispositif étant réalisé sous la forme d'un portique pourvu de moyens de déplacement assurant sa translation selon une direction donnée au-dessus de la surface sensiblement perpendiculairement à la largeur de ladite surface, le portique comportant d'une part un arbre central équipé à chaque extrémité d'au moins une roue distante l'une de l'autre d'une mesure supérieure à la largeur de la surface et d'autre part un mandrin d'enroulement et de déroulement pour l'élément de couverture, entraîné en rotation par des moyens d'entraînement.The present invention therefore aims to achieve such an objective by providing a device for covering and uncovering a surface using a roll-up cover element, the device being designed as a gantry provided with displacement means ensuring its translation in a given direction above the surface substantially perpendicular to the width of said surface, the gantry comprising on the one hand a central shaft equipped at each end with at least one wheel remote from each other; a measurement greater than the width of the surface and secondly a winding mandrel and unwinding for the cover member, rotated by drive means.

Selon l'invention, l'arbre central est pourvu de moyens de guidage en rotation pour le mandrin qui s'étend autour dudit arbre en étant monté libre en rotation par rapport à l'arbre central et en ce que les moyens de déplacement comportent un organe manuel de manoeuvre adapté pour permettre d'exercer un effort sur le portique dans sa direction de déplacement.According to the invention, the central shaft is provided with rotational guiding means for the mandrel which extends around said shaft being mounted free to rotate relative to the central shaft and in that the displacement means comprise a manual operating member adapted to allow to exert a force on the gantry in its direction of travel.

Avantageusement, les moyens de déplacement supportent en partie les moyens d'entraînement.Advantageously, the displacement means partially support the drive means.

Selon un exemple de réalisation, les moyens de déplacement comporte un corps support pour les moyens d'entraînement en rotation embarqués, ce corps support étant supporté par l'arbre central à proximité d'une roue.According to an exemplary embodiment, the displacement means comprises a support body for the onboard rotational drive means, this support body being supported by the central shaft near a wheel.

De préférence, l'organe manuel de manoeuvre est une poignée de préhension adaptée sur le corps support.Preferably, the manual operating member is a handle adapted on the support body.

Avantageusement, le corps support est équipé d'un organe de roulement facilitant le déplacement du portique selon sa direction de déplacement.Advantageously, the support body is equipped with a rolling member facilitating the movement of the gantry according to its direction of travel.

Selon un mode de réalisation, les moyens d'entraînement en rotation comportent un réducteur accouplé en rotation avec le mandrin et avec un organe moteur d'entraînement supporté par le corps support.According to one embodiment, the rotational drive means comprise a reducer coupled in rotation with the mandrel and with a drive motor member supported by the support body.

Selon un autre mode de réalisation, les moyens d'entraînement en rotation comportent un moto-réducteur accouplé en rotation avec le mandrin.According to another embodiment, the rotary drive means comprise a geared motor coupled in rotation with the mandrel.

Avantageusement, les moyens d'entraînement en rotation comportent des moyens de commande en sens contraire pour assurer l'enroulement ou le déroulement de l'élément de couverture par rapport au mandrin.Advantageously, the rotational drive means comprise control means in the opposite direction to ensure the winding or unwinding of the cover element relative to the mandrel.

Un autre inconvénient du dispositif de manutention décrit par le brevet FR 2 789 425 apparaît lorsque l'élément de couverture vise à recouvrir un bassin. En effet, l'élément de couverture est destiné à être déposé sur la surface de l'eau du bassin de sorte qu'un tel élément à caractère souple n'est pas adapté pour supporter une personne telle qu'un enfant tombant dans le bassin.Another disadvantage of the handling device described by the patent FR 2 789 425 appears when the cover element is intended to cover a pond. Indeed, the cover element is intended to be deposited on the water surface of the pool so that such a flexible element is not adapted to support a person such as a child falling into the pool .

Un autre objet de l'invention vise à remédier à cet inconvénient en proposant un nouveau procédé pour recouvrir et découvrir une surface à l'aide d'un élément de couverture enroulable adapté pour supporter le poids d'une personne.Another object of the invention is to remedy this drawback by proposing a new method for covering and uncovering a surface using a roll-up cover element adapted to support the weight of a person.

Pour atteindre un tel objectif, le procédé consiste :

  • à réaliser en tant qu'élément de couverture enroulable, un volet autoporteur de largeur supérieure à la largeur de la surface, constitué d'une série de lamelles rigides articulées et adapté pour supporter au moins le poids d'une personne lorsqu'il se trouve en appui simplement par les extrémités des lamelles rigides,
  • à dimensionner le portique de manière à être supporté par au moins les bords longitudinaux en laissant subsister avec chaque rebord longitudinal de la surface, un espace d'appui pour le volet,
  • à accrocher le volet par une extrémité, à l'un des bords transversaux de la surface et par l'autre extrémité, au mandrin motorisé,
  • et à assurer simultanément, pour couvrir la surface par le volet enroulé sur le mandrin, la commande en déroulement du mandrin et le déplacement du portique
To achieve such an objective, the method comprises:
  • to realize as a roll-up cover element, a self-supporting flap with a width greater than the width of the surface, consisting of a series of articulated rigid slats and adapted to support at least the weight of a person when it is located simply by the ends of the rigid lamellae,
  • dimensioning the gantry so as to be supported by at least the longitudinal edges, leaving, with each longitudinal rim of the surface, a support space for the flap,
  • to hang the flap at one end, at one of the transverse edges of the surface and at the other end, to the motorized mandrel,
  • and at the same time, to cover the surface by the shutter wound on the mandrel, the unwinding of the mandrel and the movement of the frame

de manière à déposer le volet au-dessus de la surface en reposant sur l'espace d'appui d'au moins des bords longitudinaux.so as to deposit the shutter above the surface by resting on the bearing space of at least longitudinal edges.

Pour découvrir la surface recouverte par le volet en appui sur les bords longitudinaux, le procédé consiste à assurer simultanément la commande en enroulement du mandrin et le déplacement du portique au-dessus de la surface en vue d'enrouler le volet sur le mandrin.To discover the surface covered by the flap resting on the longitudinal edges, the method consists in simultaneously ensuring the winding control of the mandrel and the movement of the gantry above the surface in order to wind the flap on the mandrel.

  • The Figure 1 is a schematic perspective view of a device according to the invention for covering and uncovering a surface.
  • The Figure 2 is a sectional elevation view taken substantially along the lines II-II of the Fig. 1 .

Dans l'exemple illustré sur les dessins, le dispositif 1 selon l'invention est destiné à recouvrir et découvrir à l'aide d'un élément de couverture enroulable 2, une surface 3 délimitant un espace bi ou tri-dimensionnel. L'élément de couverture 2 qui est représenté de manière schématique à la Fig. 1 , présente un caractère enroulable et est à même d'assumer une fonction de protection et/ou d'occultation. A titre d'exemple, l'élément de couverture enroulable 2 se présente sous la forme d'une bâche, d'un rideau ou d'un volet. Le dispositif 1 selon l'invention permet ainsi de recouvrir et découvrir la surface 3 par exemple d'une piscine, d'un container, d'un véhicule ou d'une salle de réunion.In the example illustrated in the drawings, the device 1 according to the invention is intended to cover and discover with the aid of a roll-up cover element 2, a surface 3 defining a two or three-dimensional space. The cover element 2 which is schematically represented in the Fig. 1 Presents a windable character and is able to perform a protective function and / or concealment. For example, the roll-up cover element 2 is in the form of a tarpaulin, a curtain or a shutter. The device 1 according to the invention thus makes it possible to cover and discover the surface 3, for example of a pool, a container, a vehicle or a meeting room.

Tel que cela apparaît plus précisément à la Fig. 2 , le dispositif 1 se présente sous la forme d'un portique comportant un arbre central 4 équipé à chaque extrémité d'au moins une roue 5 distante l'une de l'autre d'une mesure supérieure à la largeur 1 de la surface 3 à couvrir. Le portique est donc destiné à se déplacer au-dessus de la surface 3 selon une direction de translation représentée par la lettre F, sensiblement perpendiculaire à la largeur 1 de ladite surface. Les roues 5 roulent ainsi sur les bords longitudinaux 31 de la surface 3 à couvrir. De préférence, chaque roue 5 présente un diamètre supérieur à 50 cm et de préférence de l'ordre de 60 cm de manière à faciliter la mobilité du portique.As it appears more precisely in the Fig. 2 , the device 1 is in the form of a gantry comprising a central shaft 4 equipped at each end with at least one wheel 5 distant from each other by a measurement greater than the width 1 of the surface 3 to cover. The gantry is thus intended to move above the surface 3 in a translation direction represented by the letter F, substantially perpendicular to the width 1 of said surface. The wheels 5 and roll on the longitudinal edges 3 1 of the surface 3 to be covered. Preferably, each wheel 5 has a diameter greater than 50 cm and preferably of the order of 60 cm so as to facilitate the mobility of the gantry.

Selon une caractéristique préférée de réalisation, chaque roue 5 est montée sur l'arbre 4 à l'aide de moyens de montage débrayable 6. Ainsi, le débrayage d'une roue 5 par rapport à l'arbre 4 autorise un pivotement du portique autour de l'autre roue 5 liée à l'arbre 4. Par exemple, les moyens de montage débrayable 6 peuvent être réalisés par un axe de liaison traversant l'axe 4 et le moyeu 51 d'une roue 5. Selon un autre exemple de réalisation, les roues 5 peuvent être motorisées pour assurer le déplacement en translation du portique.According to a preferred embodiment, each wheel 5 is mounted on the shaft 4 by means of disengageable mounting means 6. Thus, the disengagement of a wheel 5 relative to the shaft 4 allows a pivoting of the gantry around the other wheel 5 connected to the shaft 4. For example, the disengageable mounting means 6 may be formed by a connecting pin passing through the axis 4 and the hub 5 1 of a wheel 5. According to another embodiment, the wheels 5 can be motorized to move the gantry in translation.

Le dispositif 1 selon l'invention comporte également un mandrin 7 d'enroulement et de déroulement pour l'élément de couverture 2. Le mandrin 7 s'étend autour de l'arbre 4 entre les deux roues 5. Tel que cela ressort plus précisément de la Fig. 2 , le mandrin 7 est guidé en rotation par des moyens de guidage 8 montés sur l'arbre central 4. Il est à noter que le mandrin 7 est monté libre en rotation par rapport à l'arbre central 4. En d'autres termes, il n'existe aucune liaison angulaire entre le mandrin 7 et l'arbre central 4. Dans l'exemple illustré, le mandrin 7 est supporté à chaque extrémité par un palier de guidage 8 monté sur l'arbre central 4. Le mandrin 7 entoure ainsi de manière concentrique l'arbre central 4. The device 1 according to the invention also comprises a mandrel 7 for winding and unfolding for the covering element 2. The mandrel 7 extends around the shaft 4 between the two wheels 5. As it appears more precisely of the Fig. 2 , The mandrel 7 is guided in rotation by the guide means 8 mounted on the central shaft 4. It should be noted that the mandrel 7 is rotatably mounted with respect to the central shaft 4. In other words, there is no angular connection between the mandrel 7 and the central shaft 4. In the example shown, the mandrel 7 is supported at each end by a guide bearing 8 mounted on the central shaft 4. The mandrel 7 surrounds thus concentrically the central shaft 4.

Le dispositif 1 selon l'invention comporte également des moyens d'entraînement en rotation 11 du mandrin 7 de manière à assurer l'enroulement ou le déroulement de l'élément de couverture 2 autour dudit mandrin. Selon une caractéristique de l'invention, les moyens d'entraînement en rotation 11 sont embarqués sur le portique. Ces moyens d'entraînement en rotation 11 sont équipés de moyens de commande non représentés permettant de piloter la rotation du mandrin 7 selon les deux sens opposés de rotation permettant de sélectionner l'enroulement ou le déroulement de l'élément de couverture 2 autour du mandrin 7. The device 1 according to the invention also comprises means for driving in rotation 11 of the mandrel 7 so as to ensure the winding or unwinding of the cover member 2 around said mandrel. According to one characteristic of the invention, the rotary drive means 11 are embedded on the gantry. These rotational drive means 11 are equipped with not shown control means for controlling the rotation of the mandrel 7 in two opposite directions of rotation to select the winding or unwinding of the cover member 2 around the mandrel 7.

Les moyens d'entraînement en rotation 11 sont réalisés de toute manière appropriée et peuvent être de nature fluidique, électrique ou manuelle. Dans l'exemple illustré, les moyens d'entraînement en rotation 11 comportent un réducteur 12 accouplé en rotation avec le mandrin 7 et avec un organe moteur d'entraînement non représenté supporté par un corps 13. Par exemple, un tel organe moteur d'entraînement est un moteur électrique embarqué monté à l'intérieur du corps support 13 situé à une extrémité du portique. Selon une autre variante de réalisation, le réducteur 12 peut être relié à une tête de réception pour un moteur amovible, ou pour un organe d'entraînement manuel. Selon encore une autre variante de réalisation, les moyens d'entraînement en rotation 11 peuvent être réalisés par un moteur électrique tubulaire interposé entre l'arbre 4 et le mandrin 7. The rotary drive means 11 are made in any suitable manner and may be fluidic, electric or manual in nature. In the example illustrated, the rotary drive means 11 comprise a gear 12 coupled in rotation with the mandrel 7 and with a not shown drive motor member supported by a body 13. For example, such a motor member of FIG. drive is an onboard electric motor mounted inside the support body 13 located at one end of the gantry. According to another embodiment, the gear 12 may be connected to a receiving head for a removable motor, or for a manual drive member. According to yet another variant embodiment, the rotary drive means 11 can be carried out by a tubular electric motor interposed between the shaft 4 and the mandrel 7.

Tel que cela ressort de la description qui précède, le corps support 13 est adapté pour reprendre le couple de basculement des moyens d'entraînement en rotation 11. Dans l'exemple illustré, le corps support 13 est supporté par l'arbre central à proximité d'une roue 5 et se trouve en contact avec le sol S. As is apparent from the foregoing description, the support body 13 is adapted to take up the tilting torque of the rotary drive means 11. In the illustrated example, the support body 13 is supported by the central shaft in the vicinity a wheel 5 and is in contact with the ground S.

Selon une autre caractéristique de l'invention, le portique est pourvu de moyens de déplacement 14 assurant sa translation selon la direction F. Conformément à la variante de réalisation préférée illustrée sur les dessins, les moyens de déplacement 14 sont de type manuel et comportent un organe manuel de manoeuvre 15 adapté pour exercer un effort manuel sur le portique dans sa direction de déplacement F, comme cela sera expliqué dans la suite de la description.According to another characteristic of the invention, the gantry is provided with displacement means 14 ensuring its translation in the direction F. According to the preferred embodiment illustrated in the drawings, the displacement means 14 are of manual type and comprise a manual operating member 15 adapted to exert a manual effort on the gantry in its direction of travel F, as will be explained in the following description.

Dans l'exemple de réalisation illustré, les moyens de déplacement 14 supportent au moins en partie les moyens d'entraînement 11 du mandrin 7. A cet égard, les moyens de déplacement 14 sont constitués par le corps support 13 se présentant sous la forme d'un bras prolongeant sensiblement à l'équerre l'arbre central 4 et se terminant par l'organe de manoeuvre 15 tel qu'une poignée de préhension. Selon cet exemple de réalisation, l'opérateur lors du déplacement du portique, se déplace le long d'un bord longitudinal 31 de la surface à couvrir 3. In the exemplary embodiment illustrated, the displacement means 14 support, at least in part, the drive means 11 of the mandrel 7. In this respect, the displacement means 14 are constituted by the support body 13 which is in the form of an arm extending substantially perpendicular to the central shaft 4 and ending with the actuating member 15 such as a handle. According to this embodiment, the operator upon movement of the gantry, moves along a longitudinal edge 3 1 of the surface to cover 3.

Selon une variante préférée de réalisation, le corps support 13 est équipé d'un organe de roulement 18 facilitant le déplacement du portique selon sa direction de déplacement F. L'organe de roulement 18 tel qu'une roue est apte à rouler ainsi selon une direction parallèle à la direction de roulement des roues 5. La roue 18 est montée à l'extrémité d'une fourche 19 s'étendant à partir du bras 13 de manière que lorsque les moyens de déplacement 14 reposent sur le sol S, par la roue 18, la poignée 15 est positionnée correctement pour permettre à un utilisateur, d'appliquer un effort de poussée ou de traction sur le portique afin d'assurer son déplacement longitudinal.According to a preferred embodiment, the support body 13 is equipped with a rolling member 18 facilitating the movement of the gantry according to its direction of movement F. The rolling member 18 such that a wheel is able to roll thus according to a parallel to the rolling direction of the wheels 5. The wheel 18 is mounted at the end of a fork 19 extending from the arm 13 so that when the moving means 14 rest on the ground S, by the wheel 18, the handle 15 is positioned correctly to allow a user to apply a pushing force or traction on the gantry to ensure its longitudinal movement.

La mise en oeuvre du dispositif 1 selon l'invention découle directement de la description qui précède.The implementation of the device 1 according to the invention follows directly from the foregoing description.

Pour recouvrir une surface 3, le dispositif 1 selon l'invention est disposé le long d'un bord transversal 32 de la surface 3 à couvrir tout en étant placé pour enjamber cette surface selon sa largeur. L'élément de couverture enroulable 2 est attaché par une de ses extrémités sur un bord transversal 32 délimitant la surface 3 à couvrir tandis que son autre extrémité est attachée au mandrin 7 autour duquel la majeure partie de l'élément de couverture 2 est enroulé. Les moyens d'entraînement en rotation 11 sont alors commandés dans un sens conduisant au déroulement à partir du mandrin 7, de l'élément de couverture 2. Simultanément, un opérateur assure, par exemple, une traction sur le portique, à l'aide de l'organe manuel de manoeuvre 15. Cet effort de traction conduit au déplacement du portique au-dessus de la surface 3 selon la direction de déplacement F, ainsi qu'à la tension de l'élément de couverture 2 qui se trouve déroulé à partir du mandrin 7. Le dispositif 1 peut être immobilisé à n'importe quel endroit de recouvrement de la surface 3. Lorsque la surface 3 est totalement recouverte, il est à noter que l'élément de couverture 2 peut être détaché du mandrin 7 de manière à être fixé sur l'autre bord transversal 32 de la surface à couvrir 3. For coating a surface 3, the device 1 according to the invention is arranged along a transverse edge 3 2 of the surface 3 to cover while being positioned to span the surface along its width. The roll-up cover element 2 is attached by one of its ends to a transverse edge 3 2 delimiting the surface 3 to cover while its other end is attached to the mandrel 7 around which the bulk of the cover element 2 is wound. The rotational drive means 11 are then controlled in a direction leading to the unwinding from the mandrel 7, the cover member 2. Simultaneously, an operator provides, for example, traction on the gantry, using the manual operating member 15. This pulling force leads to displacement of the gantry above the surface 3 according to the traveling direction F, and the voltage of the cover member 2 which is held in from the mandrel 7. The device 1 can be immobilized at any overlapping location of the surface 3. When the surface 3 is completely covered, it should be noted that the cover element 2 can be detached from the mandrel 7 of so as to be fixed on the other transverse edge 3 2 of the surface to be covered 3.

Pour découvrir la surface 3, à l'aide de l'élément de couverture 2 attaché par une de ses extrémités au mandrin d'enroulement 7, les moyens d'entraînement en rotation 11 sont commandés de manière à assurer l'enroulement de l'élément de couverture 2 autour du mandrin 7. Dans la mesure où l'élément de couverture 2 est fixé par son autre extrémité au bord transversal 32 de la surface 3, l'enroulement de l'élément de couverture 2 conduit au déplacement du portique selon sa direction F de sorte que l'opérateur exerce un effort minimum par exemple de poussée sur l'organe de manoeuvre 15. To discover the surface 3, using the cover element 2 attached by one of its ends to the winding mandrel 7, the rotary drive means 11 are controlled so as to ensure the winding of the cover element 2 around the mandrel 7. Insofar as the covering element 2 is fixed at its other end to the transverse edge 3 2 of the surface 3, the winding of the covering element 2 leads to the displacement of the gantry in its direction F so that the operator exerts a minimum force for example of thrust on the operating member 15.

Il ressort de ce qui précède que le dispositif 1 selon l'invention permet de recouvrir et découvrir une surface facilement, sans toutefois apporter des aménagements complexes de guidage sur les bords de la surface à recouvrir. Par ailleurs, le dispositif de manutention 1 selon l'invention offre l'avantage de pouvoir recouvrir et découvrir une surface sans nécessiter le déploiement d'efforts importants.It follows from the foregoing that the device 1 according to the invention makes it possible to cover and discover a surface easily, without, however, providing complex guide arrangements on the edges of the surface to be covered. Furthermore, the handling device 1 according to the invention offers the advantage of being able to cover and discover a surface without requiring the deployment of significant efforts.

Un autre avantage du dispositif de manutention 1 selon l'invention est de permettre le déploiement d'un élément de couverture 2 de forme analogue à celle de la surface 3 soit directement sur la surface 3 telle que sur la surface de l'eau d'un bassin par exemple, soit au moins sur les bords longitudinaux 31 afin d'éviter un contact entre la surface de l'eau et l'élément de couverture 2. Selon ce dernier exemple d'application, le procédé selon l'invention vise à réaliser en tant qu'élément de couverture enroulable 2, un volet autoporteur de largeur supérieure à la surface 3 de manière qu'il puisse reposer sur les bords longitudinaux 31 de la surface et éventuellement sur le bord transversal 32 opposé de celui à partir duquel le volet est fixé. Il est à noter que le volet autoporteur est en appui selon le bord transversal 32 sur lequel il est fixé. Le volet autoporteur peut donc être réalisé selon diverses formes similaires à celles de la surface 3, en présentant des dimensions supérieures afin de reposer sur les bords de la surface 3. Another advantage of the handling device 1 according to the invention is to allow the deployment of a cover element 2 of similar shape to that of the surface 3 either directly on the surface 3 such as on the surface of the water. a basin for example, at least on the longitudinal edges 3 1 in order to avoid contact between the water surface and the cover member 2. according to the latter application example, the process according to the invention is to realize as a roll-up cover element 2, a self-supporting flap of greater width than the surface 3 so that it can rest on the longitudinal edges 3 1 of the surface and possibly the transverse edge 3 2 opposite to that from which the flap is secured. It should be noted that the self-supporting part is supported by transverse edge 3 2 of which it is fixed. The self-supporting flap can therefore be made in various shapes similar to those of the surface 3, having larger dimensions to rest on the edges of the surface 3.

Le volet autoporteur est constitué d'une série de lamelles rigides transversales articulées entre elles pour autoriser l'enroulement du volet. Un tel volet à lamelles rigides articulées est adapté pour supporter au moins le poids d'une personne lorsqu'il se trouve en appui simplement par les extrémités des lamelles rigides.The self-supporting flap consists of a series of transverse rigid slats hinged together to allow the winding of the flap. Such rigid hinged flap is adapted to bear at least the weight of a person when it is supported simply by the ends of the rigid slats.

Bien entendu, le dispositif de manutention qui est réalisé sous la forme d'un portique déplaçable selon une direction de translation au-dessus de la surface 3, comporte un mandrin motorisé de largeur adapté pour recevoir un tel volet autoporteur. Dans le même sens, le portique est dimensionné de manière à être supporté par les bords longitudinaux 31 en laissant subsister avec chaque rebord longitudinal 33 de la surface 3, un espace d'appui 25 pour le volet autoporteur.Of course, the handling device which is made in the form of a gantry movable in a direction of translation above the surface 3, comprises a motorized mandrel of width adapted to receive such a self-supporting flap. In the same direction, the gantry is dimensioned so as to be supported by the longitudinal edges 3 1 leaving, with each longitudinal flange 3 3 of the surface 3, a bearing space 25 for the self-supporting flap.

Le recouvrement d'une surface 3 à l'aide d'un volet autoporteur est effectué comme décrit précédemment. En effet, lors de la commande en déroulement du mandrin 7 et du déplacement concomitant du portique, le volet autoporteur est déposé au-dessus de la surface 3 en reposant sur l'espace d'appui 25 jouxtant les bords longitudinaux 31. Bien entendu, le volet autoporteur repose sur une surface des bords suffisamment grande pour constituer une surface rigide même lorsqu'une personne marche sur un tel volet.The covering of a surface 3 by means of a self-supporting flap is carried out as described previously. Indeed, during the unwinding command of the mandrel 7 and the concomitant movement of the gantry, the self-supporting flap is deposited above the surface 3 while resting on the bearing space 25 adjacent the longitudinal edges 3 1 . Of course, the self-supporting component rests on an edge surface large enough to form a rigid surface even when a person walks on such a flap.

L'invention n'est pas limitée aux exemples décrits et représentés car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the examples described and shown because various modifications can be made without departing from its scope.
