Description

ABRI PLIABLE EQUIPE DE POUTRES ARTICULEES A PARALLELOGRAMMES DEFORMABLES FOLDABLE SHELTER EQUIPPED WITH ARTICULATED BEAMS WITH DEFORMABLE PARALLELOGRAMS
DOMAINE TECHNIQUETECHNICAL AREA
L'invention concerne le domaine technique des abris démontables destinés à protéger temporairement une aire d'activité, telle que par exemple une zone de culture 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 growing area or even a swimming pool.
ART ANTERIEURPRIOR ART
Il est connu dans le domaine ci-dessus, des abris démontables constitués d'arceaux indépendants enfoncés dans le sol sur lesquels est adaptée une bâche en matériau translucide. De tels abris donnent entière satisfaction quant à leur fonction de protection d'une aire.It is known in the above field, demountable shelters consisting of independent arches sunk into the ground on which is fitted a tarpaulin made of translucent material. Such shelters give complete satisfaction with their protective function of an area.
Toutefois, les opérations de montage ou 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.However, the assembly or disassembly operations of such a shelter make it particularly unsuitable for use involving frequent installation and removal, depending on weather conditions.
L'art antérieur a apporté une solution partielle à ce problème en proposant des abris pliants dont la mise en oeuvre 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, the implementation of which is particularly suitable for the protection of outdoor swimming pools without it being necessary to consider that this is their only possible application.
L'invention vise plus particulièrement des abris du type ci-dessus.The invention relates more particularly to shelters of the above type.
L'art antérieur connaît, par exemple, des abris de piscine formés de voûtes, en panneaux de polycarbonate, emboîtables et déplaçables au-dessus de la piscine à protéger.The prior art knows, for example, swimming pool shelters formed by arches, made of polycarbonate panels, nestable and movable above the swimming pool to be protected.
En période d' inutilisation de l'abri, les voûtes sont emboîtées les unes dans les autres à l'une des extrémités de la piscine. Lorsqu'il est nécessaire de protéger la piscine, les voûtes sont déplacées au-dessus de celle-ci, de façon à être juxtaposées les unes aux autres pour en recouvrir toute la surface. L'abri ainsi constitué protège efficacement la piscine tout en permettant son utilisation. Un tel abri donne satisfaction quant à sa fonction de protection mais présente néanmoins des inconvénients majeurs inhérents à sa nature.When the shelter is not in use, the vaults are fitted into each other at one end of the pool. When it is necessary to protect the pool, the arches are moved above it, so as to be juxtaposed with each other to cover the entire surface. The shelter thus constituted effectively protects the swimming pool while allowing its use. Such a shelter gives satisfaction as to its protective function but nevertheless has major drawbacks inherent in its nature.
Tout d'abord, le matériau de fabrication des voûtes est particulièrement onéreux de sorte que l'abri présente dans son ensemble, un coût de fabrication et de commercialisation particulièrement élevé.First of all, the material for manufacturing the vaults is particularly expensive so that the shelter as a whole has a particularly high manufacturing and marketing cost.
Ensuite, la manoeuvre des voûtes nécessite l'intervention de deux opérateurs disposés de part et d'autre de la piscine. En effet, les deux opérateurs doivent assurer un déplacement rectiligne des voûtes pour éviter tout coincement relatif des voûtes. De plus, en position emboîtée, l'abri possède un encombrement important par rapport à la surface couverte en phase d'utilisation. Enfin, il a été constaté que de tels abris ne présentaient pas de bonnes qualités de résistance au vent.Then, the operation of the vaults requires the intervention of two operators arranged on either side of the pool. Indeed, the two operators must ensure a rectilinear movement of the vaults to avoid any relative jamming of the vaults. In addition, in the nested position, the shelter has a large footprint relative to the covered area during use. Finally, it was found that such shelters did not have good qualities of wind resistance.
L'art antérieur connaît également des abris pliables comportant une structure supportant une bâche souple et formée de membrures ou d'arceaux liés les uns aux autres par des bras pliables. Les membrures sont munies de roulettes et peuvent être déplacées sur les côtés de la piscine de manière à déployer l'abri au- dessus de celle-ci.The prior art also knows foldable shelters comprising a structure supporting a flexible tarpaulin and formed of frames or arches linked to each other by foldable arms. The frames are fitted with rollers and can be moved on the sides of the pool so as to deploy the enclosure above it.
Un tel abri de conception légère présente un coût de fabrication nettement inférieur à celui d'un abri réalisé en panneaux de polycarbonate. Toutefois, la liaison des différentes membrures par des bras articulés ne permet pas de conférer à la structure porteuse une rigidité suffisante pour permettre un déploiement simple et rapide de l'abri. Il doit même être considéré que la liaison entre les différentes membrures est susceptible d'engendrer des dysfonctionnements sérieux lors du déploiement de l'abri. De plus, il n'est pas possible à un opérateur seul d'effectuer les opérations de déploiement et de repliement de l'abri du type ci-dessus, dont la mise en oeuvre ne peut pas être automatique. Enfin, l'absence de rigidité de la structure porteuse ne permet pas à cet abri pliable de présenter des qualités de résistance au vent satisfaisantes. EXPOSE DE L'INVENTIONSuch a light design shelter has a significantly lower manufacturing cost than a shelter made of polycarbonate panels. However, the connection of the different members by articulated arms does not allow the supporting structure to be given sufficient rigidity to allow simple and rapid deployment of the shelter. It should even be considered that the connection between the different members is likely to cause serious dysfunctions during the deployment of the shelter. In addition, it is not possible for an operator alone to carry out the operations of deployment and folding of the shelter of the above type, the implementation of which cannot be automatic. Finally, the absence of rigidity of the supporting structure does not allow this foldable shelter to have satisfactory wind resistance qualities. STATEMENT OF THE INVENTION
Le but de l'invention est de proposer un abri de conception nouvelle qui obvie aux inconvénients ci-dessus. L'invention vise, plus particulièrement, à proposer un nouvel abri pliable qui présente des caractéristiques de rigidité lui conférant une bonne résistance aux intempéries, ainsi que la possibilité d'être manoeuvré facilement par un seul utilisateur. De plus, l'invention vise à proposer un nouvel abri pliable présentant un coût de fabrication nettement inférieur à celui d'un abri réalisé en panneaux de polycarbonate transparent.The object of the invention is to provide a shelter of new design which overcomes the above drawbacks. The invention aims, more particularly, to provide a new folding shelter which has rigidity characteristics giving it good resistance to weathering, as well as the possibility of being easily maneuvered by a single user. In addition, the invention aims to provide a new foldable shelter having a manufacturing cost significantly lower than that of a shelter made of transparent polycarbonate panels.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION
Comme cela ressort de la fig. 1 , l'abri pliable selon l'invention est constitué d'une structure porteuse désignée dans son ensemble par la référence 1, sur laquelle est adaptée une bâche 2 en matériau souple. L'abri conforme à l'invention est destiné à recouvrir ou protéger une aire 3, représentée en traits mixtes, telle que par exemple une piscine délimitée par un rebord 4 formant un support pour la structure 1.As shown in fig. 1, the foldable shelter according to the invention consists of a support structure designated as a whole by the reference 1, on which is fitted a sheet 2 made of flexible material. The shelter according to the invention is intended to cover or protect an area 3, shown in phantom, such as for example a swimming pool delimited by a rim 4 forming a support for the structure 1.
La structure porteuse 1 comprend au moins deux et selon l'exemple illustré, quatre membrures 5,, 52, 53, 54. De manière préférée mais non nécessaire, les membrures 5, à 54 sont toutes sensiblement identiques. Chacune d'elles présente une forme d'arceau sous-tendu par un faux-entrait 6 horizontal et renforcé par un poinçon central 7 reliant le faux-entrait 6 à un point sommital ou sommet 8 de l'arceau. Pour des raisons de rigidité, le faux-entrait 6 est, de préférence, situé à une distance du sommet 8 égale environ au tiers de la hauteur totale des membrures 5, à 54. Afin d'être déplaçables et mobiles les unes par rapport aux autres, chacune des membrures 5, à 5 repose sur leur support 4 par l'intermédiaire de roues 9 ou encore de patins non représentés, si la nature du support 4 le permet.The supporting structure 1 comprises at least two and according to the example illustrated, four members 5, 5 2 , 5 3 , 5 4 . Preferably but not necessary, the members 5 to 5 4 are all substantially identical. Each of them has a shape of arch subtended by a horizontal false-entry 6 and reinforced by a central punch 7 connecting the false-entry 6 to a summit point or apex 8 of the arch. For reasons of rigidity, the false entry 6 is preferably located at a distance from the apex 8 equal to approximately one third of the total height of the members 5 to 5 4 . In order to be movable and movable with respect to each other, each of the members 5, to 5 rests on their support 4 by means of wheels 9 or skates not shown, if the nature of the support 4 allows it.
Deux membrures successives de la structure porteuse 1 sont reliées par au moins une poutre articulée et pliable désignée dans son ensemble par la référence 15. Seule la poutre articulée 15 reliant la première membrure 5, à la deuxième membrure 52 sera décrite, étant entendu que les poutres articulées 15 liant deux à deux les autres membrures possèdent une structure analogue. De plus, il doit être compris que les membrures externes, la première 5, et la dernière 54 sont liées seulement à une membrure intermédiaire respectivement 52 et 53, tandis que les membrures intermédiaires 52, 53 sont chacune reliées par deux poutres articulées à deux membrures voisines disposées de part et d'autre, comme cela ressort de la «g. 2.Two successive members of the supporting structure 1 are connected by at least one articulated and foldable beam generally designated by the reference 15. Only the articulated beam 15 connecting the first member 5, to the second member 5 2 will be described, it being understood that the articulated beams 15 connecting two by two the other members have a similar structure. In addition, it should be understood that the outer members, the first 5, and the last 5 4 are linked only to an intermediate member 5 2 and 5 3 respectively , while the intermediate members 5 2 , 5 3 are each connected by two articulated beams with two adjacent members arranged on either side, as shown in "g. 2.
La poutre articulée 15 comporte deux parallélogrammes déformables 16, 17 sensiblement identiques. Chaque parallélogramme 16, 17 comporte par nature, deux côtés longitudinaux et parallèles, dits supérieurs, 16,, 17, et inférieurs 162, 172, et deux côtés transversaux parallèles, dits intérieur 18 et extérieur 16-,, 173. Selon l'invention, les deux parallélogrammes 16, 17 sont liés par leurs côtés intérieurs qui forment un même côté commun 18. Les côtés longitudinaux supérieures 16,, 17, et inférieurs 162, 172 sont alors fixés respectivement aux extrémités haute et basse du côté commun 18 par des pivots 20 à 23 d'axes horizontaux.The articulated beam 15 comprises two substantially identical deformable parallelograms 16, 17. Each parallelogram 16, 17 has by nature two longitudinal and parallel sides, called upper, 16 ,, 17, and lower 16 2 , 17 2 , and two parallel transverse sides, called inside 18 and outside 16- ,, 17 3 . According to the invention, the two parallelograms 16, 17 are linked by their inner sides which form the same common side 18. The upper longitudinal sides 16, 17, and lower 16 2 , 17 2 are then fixed respectively to the upper and lower ends on the common side 18 by pivots 20 to 23 of horizontal axes.
Les deux parallélogrammes 16, 17 sont également liés chacun à une membrure distincte respectivement 5, et 52 par leur côté transversal extérieur 173, 16j parallèle au côté commun 18 et formé par le poinçon 7 de chaque membrure 5,, 52. Les côtés longitudinaux respectivement 16,, 162 et 17„ 172 sont fixés sur les poinçons 7 par l'intermédiaire de points d'articulation d'axes horizontaux 24 à 27.The two parallelograms 16, 17 are also each linked to a separate member respectively 5, and 5 2 by their external transverse side 17 3 , 16j parallel to the common side 18 and formed by the punch 7 of each member 5 ,, 5 2 . The longitudinal sides respectively 16 ,, 16 2 and 17 „17 2 are fixed to the punches 7 by means of articulation points of horizontal axes 24 to 27.
De préférence, les côtés longitudinaux inférieurs 162, 172 sont fixés sur les poinçons 7 au niveau du faux-entrait 6 de manière à définir des points d'ancrage bas 25, 27 de la poutre 15 sur les membrures 5,, 52. Ces points d'ancrage bas 25,Preferably, the lower longitudinal sides 16 2 , 17 2 are fixed to the punches 7 at the level of the false entry 6 so as to define low anchor points 25, 27 of the beam 15 on the members 5, 5 2 . These low anchor points 25,
27 sont alors situés à une distance du sommet 8 égale au tiers de la hauteur totale des membrures. La paire de parallélogrammes déformables 16, 17 ainsi constituée est sensiblement alignée avec les poinçons 7 de chaque membrure pour être sensiblement contenue dans un plan vertical médian et longitudinal de l'abri.27 are then located at a distance from the apex 8 equal to one third of the total height of the members. The pair of deformable parallelograms 16, 17 thus formed is substantially aligned with the punches 7 of each member to be substantially contained in a vertical median and longitudinal plane of the shelter.
Selon l'exemple illustré, la poutre articulée 15 comprend aussi au moins un et. de préférence, deux bras raidisseurs 28 sensiblement identiques et disposés de part et d'autre des et parallèlement aux parallélogrammes 16 et 17. Chaque bras 28 comporte deux segments 29, 30 parallèles aux deux côtés longitudinaux inférieurs 172, 162 des parallélogrammes 16, 17. Les deux segments 29, 30 possèdent une longueur sensiblement équivalente à celle des côtés longitudinaux inférieurs 162, 172 et sont assemblés par un pivot central 31 d'axe horizontal. Les deux segments 29, 30 sont, par ailleurs, chacun fixé sur le faux-entrait 6 d'une membrure voisine 5,, 52 par une liaison pivot 32, 33 d'axe également horizontal.According to the example illustrated, the articulated beam 15 also comprises at least one and. preferably, two substantially identical stiffening arms 28 and arranged on either side of and parallel to the parallelograms 16 and 17. Each arm 28 comprises two segments 29, 30 parallel to the two lower longitudinal sides 17 2 , 16 2 of the parallelograms 16, 17. The two segments 29, 30 have a length substantially equivalent to that of the lower longitudinal sides 16 2 , 17 2 and are assembled by a central pivot 31 with a horizontal axis. The two segments 29, 30 are, moreover, each fixed to the false-entry 6 of a neighboring member 5 ,, 5 2 by a pivot link 32, 33 also axis horizontal.
La poutre 15 comporte aussi une barre de liaison transversale 35 reliant les deux bras raidisseurs 28 aux parallélogrammes déformables 16, 17. Cette barre de liaison 35 est de préférence, parallèle aux faux-entraits 6 et lie les bras raidisseurs 28, au niveau de leur pivot central 31, avec l'extrémité basse du côté commun 18 portant les pivots 22, 23 des côtés longitudinaux inférieurs 162, 172. La poutre articulée 15 est ainsi susceptible d'être pliée selon un plan vertical entre deux positions extrêmes, dites dépliée et repliée. Lors du passage de cette position dépliée à la position repliée, les membrures 5,, 52 liées à la poutre 15 se déplacent alors d'une position écartée à une position rapprochée. Afin de conférer une stabilité à la poutre 15, en position dépliée, cette dernière est équipée de moyens de blocage. Dans l'exemple illustré, ces moyens de blocage sont constitués par au moins un ressort hélicoïdal 36 disposé selon une diagonale de l'un des parallélogrammes déformables 16 ou 17 et reliant le coin haut du parallélogramme orienté vers la membrure, au coin opposé. De manière préférée, la poutre comporte deux ressorts hélicoïdaux 36 équipant chacun des deux parallélogrammes déformables 16, 17. Pour former les moyens de blocage, les ressorts 36 sont complétés par deux organes de butée 37 s'opposant à tout déplacement de la poutre 15 vers le haut, au-delà de sa position dépliée. Dans l'exemple illustré, les deux organes de butée 37 sont disposés chacun sur un bras raidisseur 28 et formés par un prolongement de l'un des deux segments 29 ou 30 apte à venir en butée sur l'autre segment lorsque la poutre 15 est en position dépliée. Dans cette position, les ressorts 36 maintiennent les organes 37 en butée en empêchant la poutre 15 de se replier sous l'effet de son poids propre. En position dépliée, les côtés longitudinaux supérieurs 16,, 17, des deux parallélogrammes 16, 17 sont sensiblement alignés et il en est de même pour les côtés longitudinaux inférieurs 162, 172, de sorte que les parallélogrammes 16, 17 possèdent une forme sensiblement rectangle. La poutre 15 présente alors dans sa position dépliée, une rigidité face aux sollicitations mécaniques sensiblement parallèle aux côtés longitudinaux 16,, 162, 17,, 172.The beam 15 also includes a transverse connecting bar 35 connecting the two stiffening arms 28 to the deformable parallelograms 16, 17. This connecting bar 35 is preferably parallel to the false ties 6 and links the stiffening arms 28, at their central pivot 31, with the lower end of the common side 18 carrying the pivots 22, 23 of the lower longitudinal sides 16 2 , 17 2 . The articulated beam 15 is thus capable of being folded along a vertical plane between two extreme positions, called unfolded and folded. When passing from this unfolded position to the folded position, the members 5, 5 2 linked to the beam 15 then move from a separated position to a close position. In order to impart stability to the beam 15, in the unfolded position, the latter is equipped with locking means. In the example illustrated, these blocking means consist of at least one helical spring 36 arranged along a diagonal of one of the deformable parallelograms 16 or 17 and connecting the top corner of the parallelogram oriented towards the frame, at the opposite corner. Preferably, the beam comprises two helical springs 36 equipping each of the two deformable parallelograms 16, 17. To form the locking means, the springs 36 are completed by two abutment members 37 opposing any movement of the beam 15 towards the top, beyond its unfolded position. In the example illustrated, the two abutment members 37 are each arranged on a stiffening arm 28 and formed by an extension of one of the two segments 29 or 30 capable of coming into abutment on the other segment when the beam 15 is in the unfolded position. In this position, the springs 36 keep the members 37 in abutment by preventing the beam 15 from folding back under the effect of its own weight. In the unfolded position, the upper longitudinal sides 16, 17, of the two parallelograms 16, 17 are substantially aligned and the same is true for the lower longitudinal sides 16 2 , 17 2 , so that the parallelograms 16, 17 have a shape substantially rectangle. The beam 15 then has, in its unfolded position, a rigidity in the face of mechanical stresses substantially parallel to the longitudinal sides 16, 16 2 , 17, 17 2 .
La structure ainsi constituée est, de préférence, fabriquée selon les techniques traditionnelles de la serrurerie et de la chaudronnerie à partir de tubes cylindriques de section circulaire, réalisés en acier inoxydable ou en acier galvanisé. Les pivots d'articulation 20 à 27 et 30 à 33 sont alors formés par des manchons sur lesquels sont soudées les extrémités des segments articulés de la poutre 15 et qui sont emboîtés sur les tubes et immobilisés en translation. La structure porteuse 1 décrite ci-dessus est conçue pour pouvoir être pliée et dépliée par un seul opérateur.The structure thus formed is preferably made according to traditional locksmithing and boilermaking techniques from cylindrical tubes of circular section, made of stainless steel or galvanized steel. The articulation pivots 20 to 27 and 30 to 33 are then formed by sleeves on which the ends of the articulated segments of the beam 15 are welded and which are fitted onto the tubes and immobilized in translation. The support structure 1 described above is designed to be foldable and unfolded by a single operator.
A cette fin, la dernière membrure 54 est fixée sur le sol 4 au moyen, par exemple, de poteaux 40, comme cela apparaît aux fig. 2 à 5. L'abri comporte aussi des moyens de manoeuvre pour le dépliage, constitués de préférence mais non exclusivement, par un treuil 41 fixé sur le sol 4 et comportant un câble 42 arrimé à la première membrure 5, . Ce treuil de dépliage 41 peut être manoeuvré à la main ou mû par un motoréducteur électrique ou analogue.To this end, the last member 5 4 is fixed to the ground 4 by means, for example, of posts 40, as shown in FIGS. 2 to 5. The shelter also comprises maneuvering means for unfolding, preferably but not exclusively, constituted by a winch 41 fixed to the ground 4 and comprising a cable 42 secured to the first frame 5,. This unfolding winch 41 can be operated by hand or driven by an electric geared motor or the like.
La mise en oeuvre de l'abri s'effectue de la façon suivante. A partir d'un état complètement replié, plus particulièrement illustré à la fig. 3, sur laquelle, pour des raisons de visibilité, ni les ressorts hélicoïdaux, ni la bâche ne sont représentés. Lorsque le dépliage de l'abri est souhaité, la structure étant en position complètement repliée, le treuil 41 est actionné pour exercer, par l'intermédiaire du câble de dépliage 42, une traction sur la première membrure 5, dans le sens de la flèche f,. La première et la deuxième membrures 5,, 52 passent alors progressivement d'une position rapprochée à une position écartée, comme illustré à la fig. 4. Pendant ce déplacement, correspondant à un passage de la poutre articulée 15 de sa position repliée à sa position dépliée, le côté commun 18 des parallélogrammes 16, 17 décrit une trajectoire ascendante et conserve une orientation sensiblement verticale, tout en restant parallèle aux deux côtés externes 163, 173 formés par les poinçons 7. Les parallélogrammes déformables 16 et 17 maintiennent donc, pendant ce déplacement, le parallélisme des membrures 5,, 52, quelle que soit leur position relative. Le dépliement de la poutre 15 s'effectue alors de manière régulière.The implementation of the shelter is carried out as follows. From a completely folded state, more particularly illustrated in FIG. 3, in which, for reasons of visibility, neither the coil springs nor the cover are shown. When the unfolding of the shelter is desired, the structure being in the fully folded position, the winch 41 is actuated to exert, via the unfolding cable 42, traction on the first frame 5, in the direction of the arrow f ,. The first and second members 5 ,, 5 2 then progressively pass from a close position to a separated position, as illustrated in FIG. 4. During this movement, corresponding to a passage of the articulated beam 15 from its position folded back in its unfolded position, the common side 18 of the parallelograms 16, 17 describes an ascending trajectory and retains a substantially vertical orientation, while remaining parallel to the two external sides 16 3 , 17 3 formed by the punches 7. The deformable parallelograms 16 and 17 therefore maintain, during this movement, the parallelism of the members 5, 5 2 , whatever their relative position. The unfolding of the beam 15 is then carried out regularly.
De plus, il doit être considéré que pendant la phase de dépliage de la poutre 15, les ressorts hélicoïdaux 36 passant d'un état de grande extension à une extension moindre, remplissent une fonction d'assistance au dépliage. Lorsque la poutre 15 est totalement dépliée, les organes 37 étant en butée, les mêmes ressorts 36 assurent une fonction de blocage de la poutre 15.In addition, it must be considered that during the unfolding phase of the beam 15, the helical springs 36 passing from a state of great extension to a lesser extension, fulfill a function of assistance in unfolding. When the beam 15 is fully unfolded, the members 37 being in abutment, the same springs 36 provide a blocking function for the beam 15.
En maintenant la traction sur la première membrure 5,, il est ainsi possible de déplier toutes les poutres articulées 15 de la structure 1 pour déployer totalement l'abri au-dessus de la piscine 4. Les membrures 5, à 54 sont alors toutes en position écartée les unes des autres comme cela apparaît à la fig. 2.Maintaining traction on the first member 5 ,, it is thus possible to unfold all the articulated beams 15 of the structure 1 in order to fully deploy the shelter above the pool 4. The members 5, to 5 4 are then all in position separated from each other as shown in fig. 2.
Afin de garantir un dépliement progressif de l'abri sans risque de dysfonctionnement, il est préférable que les poutres 15 liant deux à deux les membrures 5, à 54 se déplient successivement de manière ordonnée, comme le montre la fig. 5. A cette fin, la structure 1 comporte des moyens 43 d'immobilisation relative deux à deux des membrures en position rapprochée. Ces moyens 43, illustrés aux fig. 6 et 7 mais non représentés aux fig. 1 à 5 pour des raisons de lisibilité, sont disposés entre toutes les membrures successives de la deuxième 52 à la dernière 54. Ainsi, il doit être compris que, pour l'exemple illustré, il existe des moyens d'immobilisation entre la deuxième membrure 52 et la troisième membrure 53 et entre la troisième membrure 53 et la quatrième et dernière membrure 54. Les moyens d'immobilisation 43 sont asservis en ouverture, de manière à autoriser l'écartement de deux membrures successives, lorsque la poutre 15 liant la première de ces deux membrures avec une membrure précédente est dépliée.In order to guarantee a progressive unfolding of the shelter without risk of dysfunction, it is preferable that the beams 15 connecting two by two the members 5 to 5 4 unfold successively in an orderly fashion, as shown in FIG. 5. To this end, the structure 1 comprises means 43 for immobilizing two by two of the members in the close position. These means 43, illustrated in FIGS. 6 and 7 but not shown in figs. 1 to 5 for reasons of readability, are arranged between all the successive members from the second 5 2 to the last 5 4 . Thus, it should be understood that, for the example illustrated, there are immobilization means between the second member 5 2 and the third member 5 3 and between the third member 5 3 and the fourth and last member 5 4 . The immobilization means 43 are controlled in opening, so as to allow the spacing of two successive members, when the beam 15 connecting the first of these two members with a previous member is unfolded.
Les fig. 6 et 7 illustrent une forme préférée de réalisation des moyens d'immobilisation 43 disposés entre deux membrures successives, par exemple, la troisième 53 et la deuxième 52 qui est liée par la première poutre articulée 15, à une membrure précédente non représentée, dont il sera supposé qu'il s'agit de la première membrure 5,.Figs. 6 and 7 illustrate a preferred embodiment of the immobilization means 43 arranged between two successive members, for example, the third 5 3 and the second 5 2 which is linked by the first articulated beam 15, to a previous member not shown, which will be assumed to be the first member 5 ,.
Les moyens d'immobilisation 43 sont, selon cet exemple, formés d'un bras mobile 44 fixé par un pivot 45 d'axe horizontal au faux-entrait 62 de la deuxième membrure 52pour être mobiles vers le haut, selon la direction de la flèche f2 et en butée dans une position sensiblement horizontale. L'extrémité libre du bras mobile 44 comporte un crochet 46 apte à s'engager sur le faux-entrait 63 de la troisième membrure 53 et définissant une rampe d'engagement 47 inclinée selon une direction ascendante dans un sens allant de la deuxième 52 vers la troisième membrure 53.The immobilization means 43 are, according to this example, formed of a movable arm 44 fixed by a pivot 45 of horizontal axis to the false-entry 6 2 of the second frame 5 2 to be movable upwards, in the direction of the arrow f 2 and in abutment in a substantially horizontal position. The free end of the movable arm 44 comprises a hook 46 capable of engaging on the false entry 6 3 of the third frame 5 3 and defining an engagement ramp 47 inclined in an upward direction in a direction going from the second 5 2 to the third frame 5 3 .
Les moyens d'immobilisation 43 comportent également un ressort d'asservissement en fermeture 48 qui rappelle vers le bas, en position horizontale, le bras mobile 44. Enfin, les moyens d'immobilisation 43 sont asservis en ouverture par un câble 49 reliant le bras mobile 44 au côté longitudinal supérieur 16, du parallélogramme déformable 16 lié à la seconde membrure 52 de la première poutre 15,. Lorsque la première poutre 15, est dépliée, le câble 49 entraîné par le côté longitudinal supérieur 16,, soulève le bras mobile 44. Le crochet 46 est ainsi dégagé du faux-entrait 63 de la troisième membrure 53 pour permettre l'écartement de la deuxième membrure 52 par rapport à la troisième 53 dont il doit être considéré qu'elle est immobilisée par des moyens identiques non représentés sur la quatrième et dernière membrure 5 .The immobilization means 43 also comprise a closing control spring 48 which recalls downwards, in a horizontal position, the movable arm 44. Finally, the immobilization means 43 are controlled in opening by a cable 49 connecting the arm mobile 44 at the upper longitudinal side 16, of the deformable parallelogram 16 linked to the second frame 5 2 of the first beam 15,. When the first beam 15 is unfolded, the cable 49 driven by the upper longitudinal side 16 ,, lifts the movable arm 44. The hook 46 is thus released from the false entry 6 3 of the third frame 5 3 to allow the spacing of the second member 5 2 relative to the third member 5 3 which must be considered to be immobilized by identical means not shown on the fourth and last member 5.
Il apparaît donc que grâce aux moyens d'immobilisation 43 ci-dessus, le dépliement de la seconde poutre 152 ne peut intervenir qu'après le dépliement de la première poutre 15,, comme illustré à la fig. 5. De même, le dépliement de la troisième poutre 153 n'intervient qu'après celui de la deuxième 152, de sorte que par les moyens d'immobilisation 43 et en exerçant une traction uniquement sur la première membrure, il est obtenu un dépliement séquentiel de l'abri par le passage successif des membrures d'une position rapprochée à une position écartée. Lorsque toutes les membrures sont en position écartée les unes des autres, les poutres 15 sont toutes dépliées, de sorte que l'abri est totalement déployé au-dessus de la piscine. Lorsque l'abri est complètement déplié, le câble de dépliage 42 est maintenu attaché à la première membrure 5, et le treuil 41 bloqué, de manière à former en complément avec les poteaux d'ancrage 40 de la dernière membrure 54, des moyens d'immobilisation temporaire de la structure en position dépliée sur son support 4. Ainsi arrimé au support 4 et grâce à la rigidité des poutres articulées 15 liant les membrures 5, à 54 et étant bloquées en position dépliée, l'abri présente avantageusement une bonne résistance au vent.It therefore appears that thanks to the immobilization means 43 above, the unfolding of the second beam 15 2 can only take place after the unfolding of the first beam 15 ,, as illustrated in FIG. 5. Similarly, the unfolding of the third beam 15 3 occurs only after that of the second 15 2 , so that by the immobilizing means 43 and by exerting traction only on the first member, it is obtained a sequential unfolding of the shelter by the successive passage of the members from a close position to a separated position. When all the members are in a position separated from each other, the beams 15 are all unfolded, so that the shelter is fully deployed above the pool. When the shelter is fully unfolded, the unfolding cable 42 is kept attached to the first member 5, and the winch 41 blocked, so as to complement the anchor posts 40 of the last member 5 4 , means for temporarily immobilizing the structure in the unfolded position on its support 4 Thus secured to the support 4 and thanks to the rigidity of the articulated beams 15 connecting the members 5, to 5 4 and being locked in the unfolded position, the shelter advantageously has good wind resistance.
L'abri étant destiné à pouvoir être replié, la structure porteuse 1 comporte également des moyens de manoeuvre pour en assurer le pliage par un seul opérateur. Ces moyens peuvent être constitués, par exemple, par un treuil de repliage 51 fixé sur la dernière membrure 54 et équipé d'un câble 52 ancré sur la première membrure 5,, de manière à pouvoir exercer une traction sur celle-ci dans le sens d'un rapprochement des membrures selon le sens de la flèche f4.The shelter being intended to be able to be folded, the supporting structure 1 also comprises maneuvering means for folding it by a single operator. These means can be constituted, for example, by a folding winch 51 fixed on the last member 5 4 and equipped with a cable 52 anchored on the first member 5 ,, so as to be able to exert traction on the latter in the direction of bringing the members together in the direction of the arrow f 4 .
Pour permettre un pliage automatique des poutres 15, le câble 52 passe sous les faux-entraits 6 et au-dessus des barres de liaison 35. Lorsque l'abri doit être plié, le treuil 51 est actionné pour emmagasiner le câble de repliage 52 qui exerce alors une action verticale dirigée du haut vers le bas sur les barres de liaison, ce qui tend à faire plier les poutres articulées 15. Bien entendu, avant d'effectuer toute opération de pliage de la structure, le câble de dépliage 42 est détaché de la première membrure 5,, ou le treuil 41 est débloqué. En agissant indirectement sur les moyens de blocage des poutres 15 et en rapprochant les membrures 5, à 54 les unes des autres, le câble 52 permet un pliage automatique de la structure porteuse. Pendant cette opération, la structure articulée des poutres 15 maintient avantageusement les membrures 5, à 54 parallèles entre elles, évitant ainsi tous risques de blocage. De même, pendant l'opération de repliage, chaque ressort 48 rappelle en position horizontale le bras 44 des moyens d'immobilisation 43, de sorte que grâce à la rampe 47, le crochet 46 peut s'engager automatiquement sur le faux-entrait 6 des membrures.To allow automatic folding of the beams 15, the cable 52 passes under the false ties 6 and above the connecting bars 35. When the shelter must be folded, the winch 51 is actuated to store the folding cable 52 which then exerts a vertical action directed from top to bottom on the connecting bars, which tends to bend the articulated beams 15. Of course, before performing any folding operation of the structure, the unfolding cable 42 is detached of the first member 5 ,, or the winch 41 is released. By acting indirectly on the blocking means of the beams 15 and by bringing the members 5, 5 4 together, the cable 52 allows automatic folding of the supporting structure. During this operation, the articulated structure of the beams 15 advantageously maintains the members 5 to 5 4 parallel to one another, thus avoiding any risk of blockage. Similarly, during the folding operation, each spring 48 recalls the arm 44 of the immobilizing means 43 in a horizontal position, so that, thanks to the ramp 47, the hook 46 can automatically engage on the false-entry 6 members.
Grâce à la conformation de sa structure porteuse, l'abri selon l'invention possède, en position complètement repliée, un encombrement relativement réduit par rapport à la surface couverte en position dépliée, comme cela ressort d'une comparaison des fig. 2 et 3. Enfin, pour assurer une bonne isolation par rapport à l'extérieur du volume défini par l'abri, les première 5, et dernière 54 membrures sont obturées par des panneaux de protection. La dernière membrure 54 comporte alors, de préférence, des panneaux mobiles 50 formant des portes d'accès à l'intérieur de l'abri, comme le montre la fig. 8. Bien entendu, de tels panneaux mobiles peuvent également être prévus au niveau de la première membrure 5,. Selon une variante de réalisation préférée de l'abri, les membrures 5, àThanks to the conformation of its supporting structure, the shelter according to the invention has, in the fully folded position, a relatively small size compared to the covered surface in the unfolded position, as appears from a comparison of FIGS. 2 and 3. Finally, to ensure good insulation from the outside of the volume defined by the shelter, the first 5 and last 5 4 members are closed by protective panels. The last member 5 4 then preferably comprises movable panels 50 forming access doors to the interior of the shelter, as shown in FIG. 8. Of course, such movable panels can also be provided at the level of the first member 5,. According to a preferred embodiment variant of the shelter, the members 5,
54 sont équipées de roues escamotables 9 qui permettent de faire directement reposer les membrures sur le sol 4, lorsque la structure 1 est complètement dépliée, comme le montre la fig. 5. De cette façon, il n'existe plus d'espace entre le bas de la bâche 2 et le sol 4 et l'abri possède une meilleure résistance au vent. Lorsque les membrures mobiles 5, à 54 sont équipées de roues escamotables, la dernière membrure 54 en comporte également. La dernière membrure 54 est alors et fixée à ses poteaux d'ancrage 40 par l'intermédiaire d'au moins deux et, de préférence, trois biellettes 55, de manière à pouvoir accompagner le déplacement vertical des autres membrures 5, à 53. Les fig. 9 et 10 montrent un exemple de réalisation de roues 9 escamotables. Chaque roue 9 comporte une double manivelle 56 d'axe horizontal fixée sur une membrure 5-,. La manivelle 56 présente deux bras de longueur différente dont un court 57, orienté vers l'extérieur de l'abri, porte la roue 9 à l'opposé de l'axe de la manivelle 56, et un long, dit interne, 58 orienté vers l'intérieur de l'abri. Le bras interne 58 est articulé de manière à pouvoir suivre la courbure concave de la membrure 5. En position d'utilisation, l'extrémité libre du bras interne 58 est fixée à la membrure 5 et la roue 9 porte cette membrure qui peut alors être déplacée en roulant sur son support 4. Lorsque l'abri est complètement déplié, la roue 9 peut être escamotée. Le bras interne 58 est alors détaché de la membrure 5 pour être amené dans une position sensiblement horizontale, ce qui fait pivoter la manivelle 56 et déplace la roue 9, de sorte que la membrure 5 vient reposer sur le sol 4, comme le montre la fig. 10. Grâce à son articulation, le bras interne 58 est ensuite placé dans l'alignement de la membrure précédente 52 et, de préférence mais non exclusivement, fixé à cette dernière pour conférer une meilleure rigidité à la structure porteuse 1. Le bras interne 58 peut également être engagé dans une agrafe en U 60, telle qu'illustrée à la fig. 1, adaptée sur le bas de la bâche 2. De cette manière, le bras interne 58 maintient en tension la bâche 2.5 4 are fitted with retractable wheels 9 which allow the members to rest directly on the ground 4, when the structure 1 is completely unfolded, as shown in FIG. 5. In this way, there is no longer any space between the bottom of the sheet 2 and the ground 4 and the shelter has better wind resistance. When the movable members 5 to 5 4 are fitted with retractable wheels, the last member 5 4 also has them. The last member 5 4 is then and fixed to its anchor posts 40 by means of at least two and, preferably, three rods 55, so as to be able to accompany the vertical movement of the other members 5, to 5 3 . Figs. 9 and 10 show an exemplary embodiment of retractable wheels 9. Each wheel 9 has a double crank 56 with a horizontal axis fixed to a member 5-,. The crank 56 has two arms of different length including a short 57, oriented towards the outside of the shelter, carries the wheel 9 opposite the axis of the crank 56, and a long, called internal, 58 oriented towards the interior of the shelter. The internal arm 58 is articulated so as to be able to follow the concave curvature of the member 5. In the position of use, the free end of the internal arm 58 is fixed to the member 5 and the wheel 9 carries this member which can then be moved by rolling on its support 4. When the shelter is completely unfolded, the wheel 9 can be retracted. The internal arm 58 is then detached from the frame 5 to be brought into a substantially horizontal position, which rotates the crank 56 and moves the wheel 9, so that the frame 5 comes to rest on the ground 4, as shown in the fig. 10. Thanks to its articulation, the internal arm 58 is then placed in alignment with the previous member 5 2 and, preferably but not exclusively, fixed to the latter to give better rigidity to the support structure 1. The internal arm 58 can also be engaged in a U-shaped clip 60, as illustrated in FIG. 1, adapted on the bottom of the cover 2. In this way, the internal arm 58 keeps the cover 2 in tension.
Selon une variante de réalisation non représentée, la première membrure 5, peut être équipée, à chacune de ses extrémités au niveau du support 4, d'un chariot escamotable portant deux roues alignées dans la direction de déplacement de la membrure. Une telle disposition permet d'améliorer la stabilité de la première membrure 5, par rapport au support 4 pendant les phases de pliage et de dépliage.According to an alternative embodiment not shown, the first member 5 can be equipped, at each of its ends at the level of the support 4, with a retractable carriage carrying two wheels aligned in the direction of movement of the member. Such an arrangement improves the stability of the first member 5, relative to the support 4 during the folding and unfolding phases.
L'abri ci-dessus a été décrit avec des membrures en forme d'arceaux, mais il est clair que les membrures pourraient posséder une toute autre forme, telle que par exemple celle d'une ferme.The above shelter has been described with hoop-shaped members, but it is clear that the members could have a completely different shape, such as for example that of a farm.
De même, les parallélogrammes 16 et 17 de la poutre articulée 15 ont été décrits comme se déformant dans un plan vertical médian, mais ils pourraient aussi se déformer selon un plan horizontal. Selon une variante non représentée, la poutre articulée 15 pourrait comporter deux paires de parallélogrammes 16, 17 déformables. Enfin, les membrures pourraient être liées par deux poutres articulées indépendantes disposées de part et d'autre d'un plan longitudinal de l'abri.Similarly, the parallelograms 16 and 17 of the articulated beam 15 have been described as being deformed in a vertical median plane, but they could also be deformed in a horizontal plane. According to a variant not shown, the articulated beam 15 could comprise two pairs of deformable parallelograms 16, 17. Finally, the members could be linked by two independent articulated beams arranged on either side of a longitudinal plane of the shelter.
Dans la description ci-dessus, les moyens de blocage de la poutre 15 en position dépliée sont formés par les ressorts hélicoïdaux 36 et les organes de butée 37, mais ils pourraient être formés par tous autres moyens appropriés, tels que par exemple un verrou asservi en fermeture par un ressort pour s'engager dans une gâche de blocage lorsque la poutre 15 est en position dépliée. Le verrou serait également asservi en ouverture par le câble de repliement 52 pour permettre un repliage automatique de l'abri.In the above description, the means for blocking the beam 15 in the unfolded position are formed by the coil springs 36 and the abutment members 37, but they could be formed by any other suitable means, such as for example a servo lock in closing by a spring to engage in a blocking strike when the beam 15 is in the unfolded position. The lock would also be slaved in opening by the folding cable 52 to allow automatic folding of the shelter.
Selon une autre variante de réalisation non représentée, les moyens d'assistance au dépliage de la poutre articulée 15 et de blocage de celle-ci en position dépliée peuvent être formés par un vérin électrique à vis, disposé selon une diagonale de l'un des parallélogrammes 16 ou 17 pour assurer, d'une part, une fonction de pliage et de dépliage de la poutre 15 et, d'autre part, une fonction de blocage de cette dernière en position pliée ou repliée. Toutes les poutres articulées 15 liant les membrures successives étant ainsi équipées, l'abri peut alors être simplement plié et déplié par la mise en oeuvre simultanée ou séquentielle des vérins électriques.According to another alternative embodiment, not shown, the means for assisting the unfolding of the articulated beam 15 and for blocking the latter in the unfolded position can be formed by an electric screw jack, arranged along a diagonal of one of the parallelograms 16 or 17 to ensure, on the one hand, a function of folding and unfolding of the beam 15 and, on the other hand, a function of blocking the latter in the folded or folded position. All the articulated beams 15 connecting the successive members being thus equipped, the shelter can then be simply folded and unfolded by the simultaneous or sequential implementation of the electric cylinders.
