Description

ABRI PLIABLE A STRUCTURE PORTEUSE ELASTIQUEMENT DEFORMABLE FOLDABLE SHELTER WITH ELASTICALLY DEFORMABLE CARRIER STRUCTURE
DOMAINE TECHNIQUE :TECHNICAL AREA :
L'invention concerne le domaine technique des abris démontables, destinés à protéger, temporairement, une aire d'activité, telle que, par exemple, un espace de réception ou, encore, une piscine.The invention relates to the technical field of removable shelters, intended to temporarily protect an activity area, such as, for example, a reception area or, even, a swimming pool.
TECHNIQUE ANTERIEURE :PRIOR TECHNIQUE:
Il est connu, dans le domaine ci-dessus, des abris démontables constitués d'une structure porteuse métallique tubulaire, démontable, sur laquelle est adaptée une bâche de toit et des bâches de côtés. De tels abris donnent entière satisfaction quant à leur fonction de protection d'une aire.It is known, in the above field, removable shelters consisting of a tubular metal support structure, removable, on which is fitted a roof tarpaulin and side tarpaulins. Such shelters give complete satisfaction with their protective function of an area.
Toutefois, les opérations de montage et de démontage d'un tel abri le rendent particulièrement inadapté à une utilisation impliquant des mises en place et des retraits fréquents, selon les conditions climatiques notamment.However, the assembly and disassembly operations of such a shelter make it particularly unsuitable for use involving frequent set-ups and withdrawals, depending on the climatic conditions in particular.
L'art antérieur a apporté une solution partielle à ce problème en proposant des abris pliants dont la mise en œuvre est particulièrement adaptée pour la protection des piscines extérieures, sans qu'il faille considérer que ce soit leur unique application possible.The prior art has provided a partial solution to this problem by proposing folding shelters whose implementation is particularly suitable for the protection of outdoor swimming pools, without it being necessary to consider that this is their only possible application.
Ainsi, le brevet US 3 469 596 a proposé un abri de piscine présentant une structure porteuse comprenant une série d'arceaux métalliques liés les uns aux autres deux à deux successivement par des entretoises métalliques pliables et montées sur des chariots coopérant avec deux rails de guidage sensiblement parallèles disposés sur le sol.Thus, US Pat. No. 3,469,596 has proposed a swimming pool enclosure having a supporting structure comprising a series of metal arches linked to each other two by two successively by foldable metal spacers and mounted on carriages cooperating with two guide rails substantially parallel arranged on the ground.
Un tel abri donne entière satisfaction quant à sa fonction de couverture démontable pour une piscine. Toutefois, compte tenu du caractère particulièrement lourd de la structure métallique, il n'est pas possible d'opérer rapidement une mise en place ou un retrait de l'abri, de sorte que ce dernier est, le plus généralement, déployé pour toute la durée de la saison froide et, ensuite, replié et rangé pendant toute la durée de la saison chaude. De plus, compte tenu du poids de la structure porteuse, un individu seul n'est pas en mesure de procéder au montage ou démontage de l'abri. Par ailleurs, une telle structure métallique présente, en raison de sa complexité, un coût de revient relativement important.Such a shelter gives complete satisfaction with its removable cover function for a swimming pool. However, given the particularly heavy nature of the metal structure, it is not possible to quickly set up or remove the shelter, so that the latter is, most generally, deployed for the entire duration of the cold season and then folded up and stored throughout duration of the hot season. In addition, given the weight of the supporting structure, a single individual is not able to proceed with the assembly or disassembly of the shelter. Furthermore, such a metal structure has, due to its complexity, a relatively high cost price.
EXPOSE DE L'INVENTION :PRESENTATION OF THE INVENTION:
Il apparaît donc le besoin de disposer d'un abri démontable, à même d'assurer de manière efficace la couverture et la protection d'une piscine ou d'une aire d'activités en ne présentant pas les inconvénients des abris selon l'art antérieur et, plus particulièrement, les inconvénients liés à une structure porteuse lourde et difficile à manoeuvrer. L'invention vise donc à proposer un abri pliable qui possède une masse sensiblement inférieure à celle des abris selon l'art antérieur et qui soit facile à plier, déplier et déplacer.It therefore appears the need to have a removable shelter, able to effectively cover and protect a swimming pool or an activity area while not having the drawbacks of shelters according to art. prior and, more particularly, the drawbacks associated with a heavy load-bearing structure which is difficult to maneuver. The invention therefore aims to provide a foldable shelter which has a mass substantially less than that of the shelters according to the prior art and which is easy to fold, unfold and move.
Pour atteindre cet objectif, l'invention concerne un abri pliable, du type constitué par une structure porteuse supportant une bâche et comportant au moins deux membrures mobiles l'une par rapport à l'autre le long de deux voies de guidage sensiblement parallèles. Selon l'invention, l'abri pliable est caractérisé en ce que chaque membrure comprend un arceau élastiquement déformable.To achieve this objective, the invention relates to a foldable shelter, of the type constituted by a support structure supporting a tarpaulin and comprising at least two members movable relative to one another along two substantially parallel guide tracks. According to the invention, the folding shelter is characterized in that each frame comprises an elastically deformable arch.
Afin d'assurer une bonne tenue de l'abri conforme à l'invention, selon une autre caractéristique, chaque membrure de la structure porteuse est retenue à chacune de ses deux extrémités par une voie de guidage et l'une au moins des membrures est montée coulissante sur les voies de guidage pour être déplaçable en translation le long desdites voies.In order to ensure good performance of the shelter according to the invention, according to another characteristic, each member of the supporting structure is retained at each of its two ends by a guide track and at least one of the members is sliding mounted on the guide tracks to be movable in translation along said tracks.
L'abri pliable selon l'invention, mettant en œuvre des arceaux élastiquement déformables, présente l'avantage de posséder un caractère déformable, de sorte qu'il peut s'effacer sous les forces exercées par le vent au lieu d'y résister, comme le ferait un abri à structure rigide, et retrouver ensuite sa forme initiale.The foldable shelter according to the invention, using elastically deformable arches, has the advantage of having a deformable character, so that it can fade under the forces exerted by the wind instead of resisting it, like a rigid structure shelter, and then return to its original shape.
Afin de conférer plus de rigidité à la structure, tout en préservant son caractère déformable, selon une autre caractéristique de l'invention, deux membrures successives de la structure sont liées entre elles, soit au niveau du sommet de leur arceau respectif, soit au niveau de leurs extrémités. Dans le même sens, selon encore une autre caractéristique de l'invention, une membrure, intercalée entre deux autres membrures, est reliée à l'une des deux membrures au niveau du sommet de son arceau et à l'autre membrure au niveau de ses extrémités.In order to give more rigidity to the structure, while preserving its deformable nature, according to another characteristic of the invention, two successive members of the structure are linked together, either at the level of the top of their respective hoop, or at the level of their ends. In the same direction, according to yet another characteristic of the invention, a frame, inserted between two other frames, is connected to one of the two frames at the top of its hoop and to the other frame at its extremities.
Diverses autres caractéristiques ressortent de la description ci-dessous faite en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other characteristics will emerge from the description below made with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

MEILLEURE MAND2RE DE REALISER L'INVENTION :BEST MANDATE TO IMPLEMENT THE INVENTION:
Comme cela ressort des fig. 1 et 2, un abri pliable selon l'invention présente une structure porteuse, désignée dans son ensemble par la référence 1, supportant une bâche 2 en matériau souple, éventuellement transparent. L'abri conforme à l'invention est destiné à recouvrir une aire 3, telle que par exemple une piscine délimitée par un rebord 4 formant un support pour la structure 1. La structure porteuse comprend au moins deux, et selon l'exemple illustré, une série de membrures 5ι, 52, 53 ... 5n. De manière préférée mais non strictement nécessaire, les membrures 5ι à 5„ sont toutes sensiblement identiques. Les membrures 5i à 5„ sont déplaçables les unes par rapport aux autres le long de deux voies de guidage 6 sensiblement parallèles, adaptées sur le support 4. De manière préférée, chaque extrémité des membrures est adaptée sur une voie de guidage 6 pour être retenue latéralement par celle-ci. Selon une forme préférée de réalisation de l'invention, chaque voie de guidage 6 est constituée par un câble tendu fixé sur des points d'ancrage 7 adaptés dans le sol 4. Les membrures sont alors montées coulissantes sur les câbles 6. Toutefois, la membrure extrême 5n peut être immobilisée sur les voies de guidage 6 ou leur support 4, de manière à permettre un dépliement de l'abri par simple traction sur la première membrure 5ι comme cela ressort de la suite.As shown in figs. 1 and 2, a foldable shelter according to the invention has a supporting structure, generally designated by the reference 1, supporting a sheet 2 made of flexible material, possibly transparent. The shelter according to the invention is intended to cover an area 3, such as for example a swimming pool delimited by a rim 4 forming a support for the structure 1. The supporting structure comprises at least two, and according to the example illustrated, a series of members 5ι, 5 2 , 5 3 ... 5 n . Preferably but not strictly necessary, the 5ι members to 5 „are all substantially identical. The members 5i to 5 „are movable relative to each other along two substantially parallel guide tracks 6, adapted on the support 4. Preferably, each end of the members is adapted on a guide track 6 to be retained laterally by it. According to a preferred embodiment of the invention, each guide track 6 is constituted by a tensioned cable fixed on anchor points 7 adapted in the ground 4. The members are then slidably mounted on the cables 6. However, the extreme member 5 n can be immobilized on the guide tracks 6 or their support 4, so as to allow an unfolding of the shelter by simple traction on the first member 5ι as will emerge from the following.
Comme le montre plus particulièrement la fig. 2, et conformément à une caractéristique essentielle de l'invention, chaque membrure 5ι comprend un arceau élastiquement déformable 10 qui s'étend dans un plan P illustré à la fig. 3. Par arceau élastiquement déformable, il faut entendre un arceau susceptible de connaître des déformations temporaires, sous l'effet de sollicitations, pour ensuite retrouver sa forme initiale à l'arrêt des sollicitations. Selon une forme de réalisation préférée, l'arceau élastiquement déformable est constitué par un tube sensiblement cylindrique gonflé et contraint en cintrage. Selon l'exemple illustré, l'arceau est constitué par une enveloppe textile cylindrique à l'intérieur de laquelle est introduite une vessie gonflable, gonflée à une pression de l'ordre de 1 à 1,5 bar. La forme de l'arceau 10 est alors obtenue au moyen d'un faux-entrait 11 exerçant sur les deux branches de l'enveloppe une contrainte dans le sens d'un cintrage de cette dernière. Le faux-entrait 11 peut être réalisé de toute manière appropriée, telle qu'en matière textile, telle qu'une sangle cousue à ses deux extrémités sur l'enveloppe textile ou encore sous la forme d'une barre rigide adaptée, au moyen de colliers, sur l'arceau 10. L'arceau élastiquement déformable 10 pourrait également être constitué par une enveloppe cylindrique souple et étanche ou par un cylindre de matière élastique alvéolaire, contraints en cintrage ou, encore, par un tube ou une barre flexible en matériau composite qui serait également contraint en cintrage. Bien entendu, l'arceau 10 peut également être réalisé en tout autre matériau adapté élastiquement déformable qui serait préformé et ne serait pas contraint en cintrage. De même, la contrainte en cintrage pourrait résulter de la liaison des membrures avec les voies de guidage. Selon une forme de réalisation préférée de l'invention, deux membrures successives de la structure porteuse 1 sont liées entre elles, soit au niveau du sommet 12 de leurs arceaux 10 respectifs, soit au niveau de leurs extrémités 13.As shown more particularly in FIG. 2, and in accordance with an essential characteristic of the invention, each frame 5ι comprises an elastically deformable arch 10 which extends in a plane P illustrated in FIG. 3. By elastically deformable arch, it is meant an arch capable of experiencing temporary deformation, under the effect of stresses, in order to then regain its initial shape when the stresses stop. According to a preferred embodiment, the elastically deformable arch is constituted by a substantially cylindrical tube inflated and constrained in bending. According to the example illustrated, the hoop is constituted by a cylindrical textile envelope inside which is introduced an inflatable bladder, inflated to a pressure of the order of 1 to 1.5 bar. The shape of the arch 10 is then obtained by means of a false entry 11 exerting on the two arms of the envelope a constraint in the direction of bending of the latter. The false entry 11 can be made in any suitable manner, such as in textile material, such as a strap sewn at its two ends on the textile casing or in the form of a suitable rigid bar, by means of collars, on the arch 10. The elastically deformable arch 10 could also be constituted by a flexible and tight cylindrical envelope or by a cylinder of elastic cellular material, constrained in bending or, again, by a tube or a flexible bar of material composite which would also be constrained in bending. Of course, the arch 10 can also be made of any other suitable elastically deformable material which would be preformed and would not be constrained in bending. Likewise, the bending stress could result from the connection of the members with the guide tracks. According to a preferred embodiment of the invention, two successive members of the support structure 1 are linked together, either at the level of the apex 12 of their respective arches 10, or at their ends 13.
La liaison de deux membrures successives par le sommet 12 de leurs arceaux 10 respectifs, telles que les membrures 5ι et 52, est par exemple effectuée, au moyen de deux manchons textiles 14 qui enveloppent chacun deux des sommets et qui sont reliés par une bande textile 14. formant charnière, comme cela ressort de la fig. 3. Bien entendu la liaison au sommet 12 des arceaux 10 pourrait être réalisée de toute autre manière appropriée laissant, de préférence, subsister une possibilité de rotation relative des membrures comme cela apparaîtra par la suite.The connection of two successive members by the top 12 of their respective arches 10, such as members 5ι and 5 2 , is for example carried out, by means of two textile sleeves 14 which each surround two of the tops and which are connected by a strip textile 14. forming a hinge, as shown in FIG. 3. Of course the connection to the top 12 of the arches 10 could be carried out in any other appropriate manner leaving, preferably, a possibility of relative rotation of the members remaining as will appear later.
Lorsque deux membrures successives sont liées entre elles au niveau de leurs extrémités 13, telles que les membrures 52 et 5 , elles le sont, de préférence, au moyen d'un coulisseau 15 qui est adapté sur une voie de guidage 6 et sur lequel sont montées les extrémités correspondantes des arceaux gonflables 10. Il doit être noté qu'un même coulisseau 15 assure alors, d'une part, l'adaptation des membrures sur leurs voies de guidage et, d'autre part, la liaison de deux membrures successives par leurs extrémités. De manière préférée, chaque arceau gonflable est monté sur le coulisseau par l'intermédiaire d'une tête d'ancrage 16 articulée. Cette tête 16 est alors susceptible de connaître une rotation selon au moins un axe x-x' perpendiculaire aux voies de guidage 6. Comme le montre plus particulièrement la fig. 4, chaque coulisseau présente une voie 17 de passage et de retenue pour le câble 6. De plus, lorsque le coulisseau 15 est susceptible de venir en appui sur le support 4 des voies de guidage 6, comme cela est le cas pour l'exemple illustré, il possède des galets 18 ou des patins.When two successive members are linked together at their ends 13, such as members 5 2 and 5, they are preferably so by means of a slide 15 which is fitted on a guide track 6 and on which are mounted the corresponding ends of the inflatable arches 10. It should be noted that the same slide 15 then ensures, on the one hand, the adaptation of the members on their guide tracks and, on the other hand, the connection of two members successive by their ends. Preferably, each inflatable arch is mounted on the slider by means of an articulated anchoring head 16. This head 16 is then likely to undergo a rotation along at least one axis xx 'perpendicular to the guide tracks 6. As shown more particularly in FIG. 4, each slider has a passage 17 and a retaining path for the cable 6. In addition, when the slider 15 is capable of coming to bear on the support 4 of the guide tracks 6, as is the case for the example illustrated, it has rollers 18 or pads.
Selon une autre caractéristique préférée de l'invention, plus particulièrement mise en évidence par le schéma de la fig. 5, afin d'assurer une plus grande rigidité à la structure porteuse 1, chaque membrure, intercalée entre deux autres membrures, telle que la membrure 52 entre les membrures 5ι et 53, est liée à l'une des deux membrures 5ι au niveau du sommet de son arceau 10 et à l'autre membrure 53 au niveau de ses extrémités 13. Cette membrure intercalée, par exemple 5î, se trouve donc reliée, par son sommet, au sommet d'une membrure adjacente, tandis que les extrémités de cette membrure intercalée sont assemblées chacune à une extrémité d'une autre membrure adjacente. Ainsi, il s'opère une sorte de triangulation des membrures de la structure porteuse 1, par l'alternance des liaisons au niveau des sommets 12 des arceaux avec les liaisons au niveau des extrémités des membrures. Cette triangulation confère, de manière avantageuse à la structure porteuse, une grande stabilité quelle que soit la position prise, de sa position repliée à celle complètement déployée.According to another preferred characteristic of the invention, more particularly highlighted by the diagram of FIG. 5, in order to ensure greater rigidity in the support structure 1, each member, interposed between two other members, such as the member 5 2 between members 5ι and 5 3 , is linked to one of the two members 5ι at level of the top of its hoop 10 and to the other member 5 3 at its ends 13. This interposed member, for example 5 i , is therefore connected, by its top, to the top of an adjacent member, while the ends of this interposed member are each assembled at a end of another adjacent member. Thus, a sort of triangulation of the members of the supporting structure 1 takes place, by the alternation of the connections at the level of the tops 12 of the arches with the connections at the ends of the members. This triangulation advantageously gives the supporting structure great stability whatever the position taken, from its folded position to that fully deployed.
La bâche 2 de l'abri est adaptée sur la structure porteuse 1 ainsi constituée, de manière à recouvrir intégralement celle-ci. Selon une forme préférée de réalisation, les bords de la bâche 1 sont adaptés de manière coulissante sur les voies de guidage 6 par l'intermédiaire d'anneaux 20, de passants ou de crochets. De plus, la bâche 2 est fixée, à intervalles réguliers, sur les coulisseaux successifs et définit leur extension ou leur écartement maximal les séparant en position dépliée. Les moyens définissant l'écartement maximal des coulisseaux pourrait, également, être formé par des butées limitant la course angulaire des têtes d'ancrage 16 ou, encore, des liens souples inextensibles reliant deux à deux les coulisseaux successifs adaptés sur une voie de guidage 6 . La bâche 2 est également retenue entre deux membrures 52-53, 5^ 5δ liées, par leurs extrémités, au moyen d'un lien élastique 21 reliant les deux coulisseaux de liaison entre lesdites membrures. Enfin, les faces d'extémité de l'abri au niveau de la première 5j et de la dernière 5n membrures sont fermées par la bâche 2 dont les bords sont maintenus au niveau de chacune de ces deux membrures par des anneaux, des crochets ou analogues 22 sur un câble transversal 23 reliant les deux coulisseaux de la membrure.The cover 2 of the shelter is adapted to the supporting structure 1 thus formed, so as to completely cover the latter. According to a preferred embodiment, the edges of the sheet 1 are adapted to slide on the guide tracks 6 by means of rings 20, loops or hooks. In addition, the cover 2 is fixed, at regular intervals, to the successive slides and defines their extension or their maximum spacing separating them in the unfolded position. The means defining the maximum spacing of the slides could also be formed by stops limiting the angular travel of the anchoring heads 16 or, again, inextensible flexible links connecting two by two the successive slides adapted on a guide track 6 . The sheet 2 is also retained between two members 5 2 -5 3 , 5 ^ 5 δ linked, by their ends, by means of an elastic link 21 connecting the two connecting slides between said members. Finally, the end faces of the shelter at the level of the first 5j and of the last 5 n members are closed by the sheet 2, the edges of which are held at each of these two members by rings, hooks or analogs 22 on a transverse cable 23 connecting the two slides of the frame.
De manière préférée, le câble 23 est fixé de manière amovible à l'une au moins de ses extrémités sur les coulisseaux. La bâche 2 présente alors, au niveau de ses faces extrêmes, des moyens de passage vers l'aire 3 protégée, telle que, par exemple, des ouvertures 24 fermées au moyen de fermetures à glissière.Preferably, the cable 23 is removably attached to at least one of its ends on the slides. The sheet 2 then has, at its end faces, means for passage to the protected area 3, such as, for example, openings 24 closed by means of slide fasteners.
De même, la bâche pourrait également présenter de telles ouvertures aménagées latéralement entre deux membrures successives.Similarly, the sheet could also have such openings arranged laterally between two successive members.
Le dépliement de l'abri, conforme à l'invention et ainsi constitué, est assuré, à partir d'une position repliée, telle qu'illustrée par la partie A de la fig. 3, dans laquelle les plans d'extension P présentent une orientation sensiblement verticale et les coulisseaux d'une même voie sont accolés les uns contre les autres. Une traction est exercée dans le sens de la flèche fi sur la première membrure 5j au moyen, par exemple, de deux brins 25 fixés sur les coulisseaux 15. Cette traction entraîne le déploiement de la structure articulée constituée par les deux premières membrures 5ι, 52, comme le montre la partie B de la fig. 3, jusqu'à tendre les deux bords opposés de la bâche reliant, au niveau de chacune des voies 6, les deux coulisseaux successifs. Lorsque ces deux bords sont tendus, la poursuite de la traction entraîne le déploiement des membrures suivantes, et ainsi de suite, jusqu'au dépliement complet de la structure porteuse.The unfolding of the shelter, in accordance with the invention and thus constituted, is ensured, from a folded position, as illustrated by part A of FIG. 3, in which the extension planes P have a substantially vertical orientation and the sliders of the same track are placed against one another. A traction is exerted in the direction of the arrow fi on the first member 5j by means, for example, of two strands 25 fixed on the slides 15. This traction causes the deployment of the articulated structure constituted by the first two members 5ι, 5 2 , as shown in part B of fig. 3, until stretching the two opposite edges of the sheet connecting, at each of the tracks 6, the two successive slides. When these two edges are stretched, the continued traction causes the deployment of the following members, and so on, until the complete unfolding of the supporting structure.
Lors du passage de la position pliée, telle qu'illustrée sur la partie A de la fig. 3, à une position dépliée, telle que représentée par la partie B de la même fig. 3, chaque membrure 5ι, 52, 53 connaît un pivotement de son plan d'extension P entre une orientation sensiblement verticale et une orientation inclinée. Ce pivotement du plan P est favorisé par, d'une part, l'articulation formée par le manchon de liaison 14 entre le sommet 12 des arceaux 10, et d'autre part, les têtes d'ancrage 16 articulées sur les coulisseaux 15. Compte tenu de la triangulation résultant de l'alternance des liaisons articulées aux sommets et aux extrémités des membrures, la structure porteuse est, de manière avantageuse, stable, aussi bien dans les positions pliées ou dépliées que dans les positions intermédiaires entre ces deux positions extrêmes.When passing from the folded position, as illustrated in part A of FIG. 3, in an unfolded position, as represented by part B of the same FIG. 3, each member 5ι, 5 2 , 5 3 experiences a pivoting of its extension plane P between a substantially vertical orientation and an inclined orientation. This pivoting of the plane P is favored by, on the one hand, the articulation formed by the connecting sleeve 14 between the top 12 of the arches 10, and on the other hand, the anchoring heads 16 articulated on the slides 15. Taking into account the triangulation resulting from the alternation of articulated connections at the tops and at the ends of the members, the supporting structure is advantageously stable, both in the folded or unfolded positions and in the intermediate positions between these two extreme positions .
Une fois l'abri totalement déplié, comme illustré à la fig. 5, la première membrure est immobilisée et il est possible de mettre en place des ancrages intermédiaires 26 des câbles 6 sur le sol 4, de manière à parfaitement plaquer l'abri sur son support.Once the shelter is fully extended, as illustrated in fig. 5, the first member is immobilized and it is possible to put in place intermediate anchors 26 of the cables 6 on the ground 4, so as to place the shelter perfectly on its support.
L'abri ainsi déplié assure une parfaite protection de l'aire à protéger 3 à laquelle il est possible d'accéder par les ouvertures pratiquées dans les faces extrêmes. Afin d'éviter tout obstacle à la circulation, les câbles transversaux maintenant la bâche en position fermée, peuvent, après ouverture de l'abri, être détachés par l'une de leurs extrémités et disposés sur le côté.The shelter thus unfolded provides perfect protection of the area to be protected 3 which can be accessed through the openings made in the end faces. In order to avoid any obstacle to circulation, the transverse cables maintaining the cover in the closed position, can, after opening of the shelter, be detached by one of their ends and arranged on the side.
Lorsqu'un repliement est souhaité, les éventuels ancrages intermédiaires sont retirés, la première membrure est libérée et il peut alors être exercé, sur celle-ci, une traction dans le sens de la flèche f2. Cette traction tend alors à ramener successivement les coulisseaux les uns contre les autres, le long de voie de guidage. Pendant ce repliement, le lien élastique ou tendeur 21, adapté sur la bâche 2 entre deux membrures 52-53, 5 -5s liées par leurs extrémités, assure un parfait guidage de celle-ci lorsqu'elle est relâchée par le rapprochement des membrures, comme le montre la partie A de la fig. 3.When a folding is desired, any intermediate anchors are removed, the first member is released and it can then be exerted on it, a traction in the direction of arrow f 2 . This traction then tends to bring the slides successively against each other, along the guideway. During this folding, the elastic link or tensioner 21, adapted on the sheet 2 between two members 5 2 -53, 5 -5s linked by their ends, ensures perfect guidance of the latter when it is released by the bringing together of the members, as shown in part A of FIG. 3.
Une fois l'abri replié, il est possible de détacher les câbles 6 de manière à les ranger contre l'abri pour ne laisser subsister aucun obstacle à la circulation sur le sol 4.Once the shelter is folded up, it is possible to detach the cables 6 so as to store them against the shelter so as to leave no obstacle to circulation on the ground 4.
Selon une variante de réalisation de l'invention, chaque coulisseau 15 présente un système 27 de frein permettant d'immobiliser en translation le coulisseau sur sa voie de guidage.According to an alternative embodiment of the invention, each slider 15 has a brake system 27 making it possible to immobilize the slider in translation on its guide track.
L'abri pliable conforme à l'invention offre, compte tenu de la légèreté de sa structure porteuse 1, une possibilité de pliage et de dépliage rapide par une personne seule. De plus, la mise en oeuvre de deux câbles tendus 6, en tant que voies de guidage, autorise une mise en place et une adaptation de l'abri sans modifications importantes des abords de l'aire à couvrir.The folding shelter according to the invention offers, given the lightness of its supporting structure 1, a possibility of folding and rapid unfolding by a single person. In addition, the use of two tensioned cables 6, as guide tracks, allows the shelter to be put in place and adapted without significant modifications to the surroundings of the area to be covered.
Dans le cadre d'une utilisation à la couverture d'une piscine, la forme des arceaux 10 laisse subsister entre la piscine et la bâche 2 un espace pour autoriser une utilisation de ladite piscine. L'abri pliable forme une protection efficace de la piscine aux intempéries. En effet, compte tenu de la nature des liaisons, du type glissière ou pivot glissant, entre les membrures et les voies de guidage, l'abri est parfaitement retenu par les voies de guidage.In the context of use for covering a swimming pool, the shape of the arches 10 leaves a space between the swimming pool and the cover 2 to allow use of the said swimming pool. The foldable enclosure forms an effective protection of the pool against bad weather. Indeed, given the nature of the connections, of the sliding type or sliding pivot, between the members and the guideways, the shelter is perfectly retained by the guideways.
En effet, la tension des câbles de guidage 6 assure, par la liaison des câbles avec les coulisseaux 15 et les anneaux 20 de la bâche, un placage efficace des bords de la bâche 2 sur le rebord ou le sol 4, qui interdit, lorsque l'abri est fermé, un accès à la piscine aux enfants, animaux et objets de toutes sortes. De plus, le caractère déformable de la structure porteuse 1 permet un effacement de l'abri sous l'effet du vent et diminue ainsi la sollicitation des voies de guidage par rapport à celle qu'exercerait un abri rigide. Par ailleurs, en cas de chute d'un individu sur l'abri, la réserve de flottabilité offerte par les arceaux gonflables 10 annule tout risque de noyade par emprisonnement dans la bâche 2.Indeed, the tension of the guide cables 6 ensures, by the connection of the cables with the sliders 15 and the rings 20 of the sheet, effective plating of the edges of the sheet 2 on the ledge or the ground 4, which prohibits, when the shelter is closed, access to the swimming pool for children, animals and objects of all kinds. In addition, the deformable nature of the supporting structure 1 allows the shelter to be erased under the effect of the wind and thus reduces the stress on the guideways relative to that which a rigid shelter would exert. Furthermore, in the event of an individual falling onto the shelter, the buoyancy reserve offered by the inflatable arches 10 cancels any risk of drowning by imprisonment in the cover 2.
Un autre avantage de l'invention réside dans la nature des arceaux 10 qui, dans leur forme préférée de réalisation, permettent, par leur dégonflage, de réduire le volume total de l'abri démonté et autorisent ainsi son rangement et son transport sans moyen lourd de manutention. Selon une forme de réalisation préférée, l'abri est complètement démontable et les arceaux 10 sont fixés de manière amovible sur les têtes d'ancrage 16 des coulisseaux de sorte qu'il est possible de démonter complètement chaque membrure constitutive de la structure porteuse. Le montage de l'abri s'effectue alors par gonflage des arceaux 10, puis adaptation des extrémités des arceaux sur les têtes d'ancrage 16 des coulisseaux 15, lesquels auront été préalablement adaptés sur les voies de guidage 6 mises sous tension sur leurs ancrages 7 aménagés dans le sol 4.Another advantage of the invention lies in the nature of the arches 10 which, in their preferred embodiment, allow, by their deflation, to reduce the total volume of the dismantled shelter and thus allow its storage and transport without heavy handling equipment. According to a preferred embodiment, the shelter is completely removable and the arches 10 are removably attached to the anchor heads 16 of the slides so that it is possible to completely disassemble each member of the supporting structure. The mounting of the shelter is then carried out by inflating the arches 10, then adaptation of the ends of the arches on the anchor heads 16 of the slides 15, which will have been previously adapted on the guide tracks 6 energized on their anchors 7 arranged in the ground 4.
Selon les exemples ci-dessus, les voies de guidage 6 sont fixées sur le sol 4. Selon une autre forme de réalisation, illustrée aux fig. 6 et 7, les voies de guidage 6, constituées par des câbles, sont adaptées en hauteur en étant chacune tendues entre deux poteaux 30. Ainsi, l'abri pliable constitue une sorte de toit, pour une aire de jeux, de réception ou de travail, qui peut être très facilement pliée ou dépliée le long des câbles de guidage, comme cela a été décrit pour l'abri au sol. A cette fin, la commande des brins de manoeuvre 25 pourra être ramenée au sol. En cas de grande portée et afin d'éviter une flèche trop importante des câbles tendus 6 formant les voies de guidage, les poteaux 30 peuvent supporter également des suspentes de reprise 31 reliées aux câbles 6. Pour assurer une fermeture des côtés de l'abri, des jupes 33 peuvent également être accrochées, soit aux câbles de guidage, soit aux fonds inférieurs de la bâche 2.According to the above examples, the guide tracks 6 are fixed to the ground 4. According to another embodiment, illustrated in FIGS. 6 and 7, the guide tracks 6, formed by cables, are adapted in height by each being stretched between two posts 30. Thus, the foldable shelter constitutes a kind of roof, for a playground, reception or work, which can be very easily folded or unfolded along the guide cables, as described for the ground shelter. To this end, the control of the operating strands 25 may be brought back to the ground. In the event of a large span and in order to avoid too great a deflection of the stretched cables 6 forming the guide tracks, the posts 30 can also support recovery lines 31 connected to the cables 6. To ensure closure of the sides of the shelter , skirts 33 can also be hung either on the guide cables or on the lower bottoms of the sheet 2.
Comme le montre en pointillé la fig. 6, il est également possible de juxtaposer plusieurs abris conformes à l'invention, de manière à constituer un ensemble de couverture d'une aire d'activité étendue.As shown in dotted lines in fig. 6, it is also possible to juxtapose several shelters in accordance with the invention, so as to constitute a cover assembly for an extended activity area.
Selon les exemples ci-dessus, les voies de guidage sont formées par des câbles tendus, mais elles pourraient tout aussi bien être constituées par des rails ou des rainures en "C" dans lesquelles seraient adaptés les coulisseaux.According to the above examples, the guide tracks are formed by tensioned cables, but they could just as easily be formed by rails or "C" grooves in which the slides would be adapted.
De même, il pourrait également être envisagé de lier ensemble directement les extrémités des arceaux gonflables au moyen de coutures en aménageant une articulation textile. Les extrémités ainsi reliées seraient alors adaptées sur les voies de guidage constituées par des câbles aux moyens de passants aménagés dans lesdites extrémités et enfilés sur les câbles. Dans les exemples ci-dessus, les membrures 5ι à 5„ de la structure porteuse sont liées les unes aux autres en alternance par leur sommet et par leur extrémités. Toutefois, il pourrait être envisagé une autre organisation de la liaison des membrures successives de la structure porteuse. De même, un abri conforme à l'invention pourrait présenter une structure porteuse dont les membrures comprenant un arceau élastiquement déformable seraient liées entre elles uniquement par l'intermédiaire de la bâche.Similarly, it could also be envisaged to directly link the ends of the inflatable arches together by means of seams by providing a textile articulation. The ends thus connected would then be adapted on the guide tracks formed by cables by means of loops arranged in said ends and threaded on the cables. In the examples above, the members 5ι to 5 „of the supporting structure are linked to each other alternately by their apex and by their ends. However, it could be envisaged another organization of the connection of the successive members of the supporting structure. Likewise, a shelter in accordance with the invention could have a supporting structure, the members of which comprising an elastically deformable arch would be linked together only by means of the sheet.
Par ailleurs, il doit être noté que la structure porteuse articulée, telle que décrite en relation avec les fig. 1 à 5, faisant intervenir une alternance de liaisons articulées aux sommets des arceaux et aux extrémités des membrures, permet, de manière avantageuse, de réduire à un nombre minimum les organes de liaison entre les membrures successives. Ainsi, cette configuration permet la réalisation, en utilisant des arceaux rigides, d'une structure porteuse rigide pliable plus légère que celles des abris pliables connus.Furthermore, it should be noted that the articulated support structure, as described in relation to FIGS. 1 to 5, involving an alternation of links articulated at the tops of the arches and at the ends of the members, advantageously makes it possible to reduce the connecting members between the successive members to a minimum number. Thus, this configuration allows the realization, using rigid hoops, of a foldable rigid support structure lighter than those of known foldable shelters.
