The structure has three frames (1, 2, 3) hinged together by pairs of bars (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b). It also has a cover (cloth or tarpaulin) whose central portion can slide on the ridge beam (12) of the structure carried by the central frame (1) thus permitting folding and unfolding of the structure together with its roof. <IMAGE>

Description

La présente invention concerne une structure déploya­ble couverte permettant d'aménager rapidement des stands de foire, des boxes pour chevaux, des abris, des aires de jeu telles que des aires de départ pour practice de golf... sur un terrain nu sans nécessité d'aménager ce terrain au préa­lable.The present invention relates to a deployable covered structure for quickly setting up fair stands, horse boxes, shelters, play areas such as starting areas for golf practice ... on bare ground without the need for '' develop this land beforehand.

Habituellement, l'aménagement de stands ou de boxes pour animaux.... est réalisé par le montage sur le site des différents montants, poteaux, traverses...nécessaires à la construction de ces structures. Ce montage implique un grand nombre d'opérations d'assemblage, donc une main d'oeuvre im­portante. En outre, il est nécessaire de disposer d'outils pour procéder à ces assemblages et les moyens d'assemblages, dont certaines pièces sont amovibles et doivent être souvent vérifiées pour remplacer les éléments perdus. Pour bien comprendre le travail que constitue une telle installation, il faut imaginer, par exemple, la mise en place de 80 boxes à chevaux, pour la préparation d'un concours hippique, se déroulant au cours d'un week-end. Il faut ensuite comprendre que l'installation démontée doit être rangée pour son trans­port et son stockage selon une procédure qui doit faciliter le montage suivant. Au cours de ce rangement, il faut repérer les pièces manquantes ou défectueuses pour compléter l'équipe­ment, afin de le rendre apte à être remonté.Usually, the layout of animal stands or boxes ... is carried out by mounting on the site the various uprights, posts, sleepers ... necessary for the construction of these structures. This assembly involves a large number of assembly operations, therefore a significant workforce. In addition, it is necessary to have tools to carry out these assemblies and the assembly means, some of which are removable and must be often checked to replace the lost elements. To fully understand the work that constitutes such an installation, it is necessary to imagine, for example, the installation of 80 horse boxes, for the preparation of a horse competition, taking place during a weekend. It must then be understood that the dismantled installation must be put away for its transport and storage according to a procedure which must facilitate the following assembly. During this storage, you must identify the missing or defective parts to complete the equipment, in order to make it suitable for reassembly.

La présente invention entend proposer une structure simple qui peut être mise en place en un temps très court et dans laquelle tous les éléments nécessaires à la constitution d'un module (par exemple 8 boxes à chevaux) sont liés de manière permanente les uns aux autres. On supprime ainsi toutes les opérations longues et fastidieuses d'assemblage, lors du montage et on minimise les pertes de matériel, d'outils rédui­sant ainsi le temps et le coût de la maintenance du dispositif.The present invention intends to propose a simple structure which can be put in place in a very short time and in which all the elements necessary for the constitution of a module (for example 8 horse boxes) are permanently linked to each other . This eliminates all the long and tedious assembly operations during assembly and minimizes the loss of material and tools, thereby reducing the time and cost of maintaining the device.

A cet effet, l'invention a pour objet une structure déployable couverte constituée par une armature centrale en forme de cadre rectangulaire et deux armatures de façade éga­ lement en forme de cadres rectangulaires, disposées de part et d'autre de l'armature centrale, et chacune reliée à cette armature centrale par au moins deux paires de barres de liaison.To this end, the subject of the invention is a covered deployable structure constituted by a central frame in the form of a rectangular frame and two frames of equal facade. Lement in the form of rectangular frames, arranged on either side of the central frame, and each connected to this central frame by at least two pairs of connecting bars.

Selon l'une des caractéristiques de l'invention, les paires de barres sont articulées par leurs extrémités aux armatures qu'elles relient, de manière à s'étendre paral­lèlement aux plans des cadres quand la structure est repliée et perpendiculairement à ces derniers, lorsque la structure est déployée, tandis qu'une couverture est formée par une bâche qui est fixée à chaque armature de façade et dont la partie en faîtage est montée à coulissement le long d'un lon­geron supérieur de l'armature centrale.According to one of the characteristics of the invention, the pairs of bars are articulated by their ends to the reinforcements which they connect, so as to extend parallel to the planes of the frames when the structure is folded back and perpendicular to the latter, when the structure is deployed, while a cover is formed by a tarpaulin which is fixed to each façade reinforcement and the ridge part of which is slidably mounted along an upper spar of the central reinforcement.

Afin de synchroniser les pivotements de part et d'autre de l'armature centrale, au moins l'une des barres de liaison de l'armature centrale à une armature de façade est attelée à l'une des barres de liaison de l'armature à l'autre armature de façade par un compas dont chaque branche est articulée à une barre et dont l'articulation commune est montée coulissante le long d'un longeron horizontal du cadre central.In order to synchronize the pivotings on either side of the central frame, at least one of the connecting bars of the central frame to a facade frame is coupled to one of the connecting bars of the frame. to the other façade reinforcement by a compass, each branch of which is articulated to a bar and whose common articulation is slidably mounted along a horizontal spar of the central frame.

On peut disposer, à la place de ce compas, des pignons engrénant entre eux et solidaires en rotation de chacune des deux barres dont on veut synchroniser le pivote­ment.We can have, instead of this compass, pinions meshing with each other and integral in rotation with each of the two bars whose pivoting we want to synchronize.

Dans un mode particulier de réalisation, chaque paire de barre appartient à un panneau de cloisonnement du volume intérieur de la structure en position déployée.In a particular embodiment, each pair of bars belongs to a partition panel of the interior volume of the structure in the deployed position.

Selon une caractéristique avantageuse de l'inven­tion, la bâche est en deux pans séparés, le bord coulissant de chaque pan de bâche étant constitué par un élément de ren­fort rigide de ce bord de pan de bâche, équipé d'une pluralité de galets montés à roulement dans un rail latéral solidaire du longeron supérieur de l'armature centrale.According to an advantageous characteristic of the invention, the cover is in two separate sections, the sliding edge of each cover section being constituted by a rigid reinforcement element of this cover side of the cover, equipped with a plurality of rollers mounted at bearing in a side rail integral with the upper spar of the central frame.

Afin d'obtenir une pente à la couverture, le rail susdit est à un niveau vertical supérieur à celui du longeron supérieur de chaque cadre de façade pour la fixation de l'autre bord de pan de bâche.In order to obtain a slope on the roof, the rail aforesaid is at a vertical level higher than that of the upper spar of each facade frame for fixing the other edge of the sheet pan.

Enfin, il sera avantageux de pourvoir le longeron supérieur du cadre central de deux anneaux de levage afin de pouvoir soulever le cadre central au moyen d'une élingue accro­chée aux deux points de levage susdit de manière que le point de soulèvement divise l'élingue en deux brins de longueurs dif­férentes, après avoir accroché le brin le plus long, soit à l'anneau du cadre qui détermine une inclinaison de ce dernier telle que l'effet de la pesanteur favorise le déploiement de la structure, soit à l'anneau du cadre qui détermine une incli­naison de la structure telle que l'effet de la pesanteur favo­rise le reploiement de la structure.Finally, it will be advantageous to provide the upper spar of the central frame with two lifting rings in order to be able to lift the central frame by means of a sling attached to the two above-mentioned lifting points so that the lifting point divides the sling into two strands of different lengths, after having hooked the longest strand, either to the ring of the frame which determines an inclination of the latter such that the effect of gravity promotes the deployment of the structure, or to the ring of the frame which determines an inclination of the structure such that the effect of gravity promotes the folding of the structure.

L'invention sera mieux comprise au cours de la des­cription donnée ci-après d'un exemple de sa réalisation plus spécialement adapté à constituer un ensemble de huit boxes pour chevaux. Cette description est donnée à titre indicatif et est faite en regard des dessins annexés dans lesquels :

  • - la figure 1 est une vue schématique de la struc­ture selon l'invention, en perspective, la structure étant semi-­déployée, la couverture n'étant pas représentée,
  • - la figure 2 est une vue en plan de la structure de la figure 1, illustrant son encombrement en position déployée et, en traits mixtes, en cours de repliement et complètement repliée,
  • - la figure 3 est une vue partielle du comportement de la bâche de couverture en cours de repliement ou de déploie­ment,
  • - la figure 4 est un schéma en coupe de la poutre faitière de la structure équipée des moyens pour guider la couverture lorsque celle-ci est d'un seul tenant,
  • - la figure 5 montre par une coupe de détail une variante de réalisation de la couverture qui comporte deux pans séparés.
The invention will be better understood during the description given below of an example of its embodiment more specially adapted to constitute a set of eight boxes for horses. This description is given for information only and is given with reference to the appended drawings in which:
  • FIG. 1 is a schematic view of the structure according to the invention, in perspective, the structure being semi-deployed, the cover not being shown,
  • FIG. 2 is a plan view of the structure of FIG. 1, illustrating its size in the deployed position and, in phantom, in the course of folding and completely folded,
  • FIG. 3 is a partial view of the behavior of the cover sheet during folding or deployment,
  • FIG. 4 is a sectional diagram of the ridge beam of the structure equipped with the means for guiding the cover when the latter is in one piece,
  • - Figure 5 shows in a detail section an alternative embodiment of the cover which has two separate sides.

En se reportant à ces figures et tout d'abord aux figures 1 et 2, on voit que la structure selon l'invention est constituée par trois armatures principales, à savoir un cadre rectangulaire central 1 et deux cadres de façade 2 et 3 disposés de chaque côté du cadre central. Dans le cas de ces figures, chaque cadre de façade est relié au cadre cen­tral par cinq paires de barres de liaison, dont celles d'ex­trémité sont notées 4a,4b et 5a, 5b pour la liaison des cadres 1 et 2 et 6a, 6b ; 7a, 7b pour la liaison des cadres 1 et 3. Ces barres sont articulées par leurs extrémités à chacun des cadres, au moyen de platines d'articulation 10 qu'ils possèdent en partie haute et en partie basse, ces pla­tines 10 étant tournées vers le cadre central 2 pour les ca­dres de façade et vers chacun de ces cadres de façade pour celles portées par le cadre central, ce qui offre un certain intérêt pour la position repliée de la structure, comme on le verra par la suite.Referring to these figures and first of all to Figures 1 and 2, it can be seen that the structure according to the invention consists of three main frames, namely a central rectangular frame 1 and two front frames 2 and 3 arranged with each side of the central frame. In the case of these figures, each front frame is connected to the central frame by five pairs of connecting bars, the end ones of which are noted 4 a , 4 b and 5 a , 5 b for the connection of frames 1 and 2 and 6 a , 6 b ; 7 a , 7 b for the connection of frames 1 and 3. These bars are articulated by their ends to each of the frames, by means of articulation plates 10 which they have at the top and at the bottom, these plates 10 being facing the central frame 2 for the front frames and towards each of these front frames for those carried by the central frame, which offers a certain interest for the folded position of the structure, as will be seen later.

Les couples de barres de liaison intermédiaires sont disposés, entre les cadres, de la même façon que ceux d'extrémité, et leur nombre dépend de la longueur de la struc­ture. La figure illustre une structure destinée à constituer huit boxes pour chevaux dont la longueur des cadres est d'en­viron 10 mètres et demi et dont la largeur déployée est de l'ordre de cinq mètres.The pairs of intermediate connecting bars are arranged between the frames in the same way as those at the end, and their number depends on the length of the structure. The figure illustrates a structure intended to constitute eight horse boxes whose frame length is approximately 10 and a half meters and whose deployed width is of the order of five meters.

Chacun des trois cadres 1, 2, 3 peut contenir des panneaux au moyen desquels on crée une séparation longitudinale du volume de la structure et on constitue des façades. Ainsi les panneaux de façade comportent-ils quatre modules dont chacun présente une allège fixe 8 surmontée d'une fenêtre à barreaux 9 et est pourvu d'une porte P. Le cadre central comporte éga­lement un panneau de cloisonnement 11 qui peut également être ajouré en imposte.Each of the three frames 1, 2, 3 may contain panels by means of which a longitudinal separation of the volume of the structure is created and facades are formed. Thus the front panels have four modules, each of which has a fixed sill 8 surmounted by a window with bars 9 and is provided with a door P. The central frame also includes a partition panel 11 which can also be perforated in transom.

Les trois cadres susdits peuvent être garnis de différentes manières pour, en façade, présenter des comptoirs, des panneaux pleins, des panneaux vitrés...The three aforementioned frames can be lined in different ways to present counters, solid panels, glass panels, etc. on the front.

Il sera en outre avantageux que les barres articulées appartiennent à des panneaux ou des cadres de cloisonnement transversaux de l'espace interne de la struc­ture. Cette disposition sera même indispensable pour les barres d'extrémité afin de contreventer la structure (voir triangulation 4c des barres 4a et 4b sur la figure 1).It will also be advantageous for the articulated bars to belong to panels or transverse partitioning frames of the internal space of the structure. This arrangement will even be essential for the end bars in order to brace the structure (see triangulation 4 c of the bars 4 a and 4 b in FIG. 1).

Chacun des cadres parallèles de la structure possè­de un longeron supérieur 12 pour le cadre central qui est représenté ici en forme de poutre faitière, 13 et 14 pour les cadres de façade 2 et 3. Ces longerons supérieurs peuvent être au même niveau, ou bien, afin de donner deux pans à la couverture de la structure (qui n'est pas représentée aux figu­res 1 et 2) le longeron 12 peut être le plus élevé. Ce longe­ron 12 présente deux anneaux d'accrochage pour la manutention de la structure symbolisés en 15 et 16 pour la mise en place d'une élingue 17.Each of the parallel frames of the structure has an upper spar 12 for the central frame which is shown here in the form of a ridge beam, 13 and 14 for the facade frames 2 and 3. These upper spars can be at the same level, or else, in order to give two sides to the cover of the structure (which is not shown in Figures 1 and 2) the spar 12 may be the highest. This spar 12 has two attachment rings for handling the structure symbolized at 15 and 16 for the installation of a sling 17.

Il faut enfin noter que le longeron 12 présente sous sa face inférieure une glissière non visible sur la figu­re 1 mais symbolisée en 18 sur la figure 2, le long de laquelle un coulisseau 19 peut coulisser. Ce coulisseau 19 constitue le sommet d'un compas dont les branches 20 et 21 sont articu­lées aux barres 4a et 6a (ou 5a, 7a) susdites. Ce compas assure le synchronisme du pivotement des barres 4a, 6a autour de leur articulation sur le cadre central. Il sera préférable pour mieux répartir les efforts de prévoir plusieurs compas au droit de chacune des paires de barres ainsi associées, à l'ex­ception d'une paire d'extrémité pour laquelle la glissière 18 ferait saillie à l'extrémité de la structure. Il faut noter également que les compas représentés figure 1 sont disposés de façon inverse de celui de la figure 2, ceci intentionnellement, pour faire apparaître deux variantes possibles d'installation.Finally, it should be noted that the spar 12 has under its underside a slide not visible in Figure 1 but symbolized at 18 in Figure 2, along which a slide 19 can slide. This slide 19 constitutes the top of a compass, the branches 20 and 21 of which are articulated to the bars 4 a and 6 a (or 5 a , 7 a ) above. This compass provides synchronism of the pivoting of the bars 4, 6a around their articulation on the middle frame. It will be preferable to better distribute the forces to provide several compasses to the right of each of the pairs of bars thus associated, with the exception of a pair of ends for which the slide 18 would protrude at the end of the structure. It should also be noted that the compasses shown in FIG. 1 are arranged inversely to that of FIG. 2, this intentionally, to reveal two possible variants of installation.

Aux lieu et place de ces compas de synchronisation du pivotement, on peut prévoir des roues dentées 22, 23 (figure 2) centrées sur les axes d'articulation des barres au cadre central et engrenant entre elles, ces roues étant angulairement solidaires des barres dont elles synchronisent le mouvement.Instead of these pivoting synchronization compasses, it is possible to provide toothed wheels 22, 23 (FIG. 2) centered on the axes of articulation of the bars to the central frame and meshing therebetween, these wheels being angularly integral with the bars, they synchronize movement.

La figure 2 illustre par une vue schématique de dessus, en trait plein la structure déployée, en traits mix­tes la structure d'une part en position intermédiaire (comme à la figure 1) et d'autre part, en position repliée. On voit que dans cette position, par la disposition des platines 10 d'articulation, les barres de liaison (ou les panneaux arti­culés qui les contiennent) se rangent parallèlement aux trois cadres de structure. En plus de la compacité ainsi obtenue, la position des panneaux, en position de rangement, supprime notamment le risque de sollicitations excessives des articu­lations.FIG. 2 illustrates by a schematic top view, in solid line the deployed structure, in phantom the structure on the one hand in the intermediate position (as in FIG. 1) and on the other hand, in the folded position. It can be seen that in this position, by the arrangement of the hinge plates 10, the connecting bars (or the articulated panels which contain them) are stored parallel to the three structural frames. In addition to the compactness thus obtained, the position of the panels, in the storage position, in particular eliminates the risk of excessive stresses on the joints.

Pour des raisons de clarté du dessin, la couverture n'a pas été représentée aux figures 1 et 2.For reasons of clarity of the drawing, the cover has not been shown in FIGS. 1 and 2.

Les figures 3 et 4 en sont une représentation schéma­tique. Cette couverture est constituée par une bâche 25 soli­daire le long d'une ligne médiane longitudinale, d'un renfort 26 qui la divise en deux pans 25a et 25b. Le bord de chaque pan parallèle au renfort 26 est fixé au longeron supérieur correspondant 13 et 14 des cadres de façade.Figures 3 and 4 are a schematic representation. This cover consists of a cover 25 secured along a longitudinal centerline, a reinforcement 26 which divides it into two sections 25 a and 25 b. The edge of each panel parallel to the reinforcement 26 is fixed to the corresponding upper beam 13 and 14 of the front frame.

L'élément 26 de renfort est quant à lui monté coulis­sant ou roulant au moyen de galets 29, dans une glissière 28 qui surmonte la poutre 12 de faîtage de la structure. Ce cou­lissement donne à la bâche de couverture suffisamment de liber­té pour que le repliement ou le dépliement puisse être réalisé sans démontage de la bâche ou déchirure de celle-ci. La figure 3 représente le plissement et le retrait de la bâche en cours de pliage par rapport à la position déployée de la structure. Lorsque la structure est complètement déployée, on immobilise le renfort 26 sur la poutre 12 par tout moyen approprié, pour par exemple aligner les extrémités de la bâche avec les pignons de la structure. En effet, la bâche peut comporter des volets d'extrémité qui retombent le long de chaque pignon.The reinforcing element 26 is in turn mounted sliding or rolling by means of rollers 29, in a slide 28 which surmounts the beam 12 of ridge of the structure. This sliding gives the cover sheet sufficient freedom so that folding or unfolding can be carried out without dismantling the sheet or tearing it. Figure 3 shows the folding and removal of the tarpaulin during folding relative to the deployed position of the structure. When the structure is fully deployed, the reinforcement 26 is immobilized on the beam 12 by any appropriate means, for example to align the ends of the sheet with the gables of the structure. In fact, the cover may include end flaps which fall down along each pinion.

La figure 5 enfin est une vue schématique en coupe d'une variante de réalisation de la bâche de couverture et de son attelage à la poutre faitière 12 de la structure.Figure 5 finally is a schematic sectional view of an alternative embodiment of the covering sheet and its coupling to the ridge beam 12 of the structure.

La bâche comprend dans ce cas, deux pans séparés tel que celui 30 du dessin. Chacun de ses pans est, comme dans la figure précédente, attaché au longeron supérieur 13,14 du cadre de façade correspondant, tandis que son autre bord est équipé d'un élément de renfort 31 qui est logé dans une cou­lisse 32 elle-même coopérant avec une glissière 33a solidaire de la poutre 12, au moyen de galets de roulement 32a. L'autre pan présente la même constitution pour coopérer avec la glis­sière symétrique 33b représentée à la figure . Pour assurer l'étanchéité de la couverture, on a prévu un panneau de pro­tection 34 recouvrant les deux coulisses, et s'étendant tout le long de la poutre 12.The cover in this case comprises two separate sections such as that of the drawing. Each of its sides is, as in the previous figure, attached to the upper spar 13,14 of the corresponding front frame, while its other edge is equipped with a reinforcing element 31 which is housed in a slide 32 itself cooperating with a slide 33 a secured to the beam 12, by means of rollers 32 a . The other pan has the same constitution to cooperate with the symmetrical rail 33 b shown in FIG. To ensure the waterproofing of the cover, a protective panel 34 has been provided covering the two slides, and extending all along the beam 12.

Enfin, revenant à la figure 1, on voit que l'élin­gue 17 possède un point de soulèvement 17a (par exemple cons­titué par un anneau) qui divise cette élingue en deux brins 17b et 17c de longueurs inégales. Le brin le plus long 17b est dans le cas de figure,attelé à l'anneau 16, ce qui implique que la structure soit légèrement inclinée vers l'arrière et vers le bas. Dans ce cas, lors de la mise en place, c'est le point 35 de la structure qui touche le sol en premier et l'effet de la pesanteur agit de manière à favoriser le déploiement de celle-ci. Lorsqu'elle est complètement déployée (les compas ci-dessus décrits ou d'autres organes forment des butées à ce déploiement), on la descend complètement pour qu'elle repose au sol par toute sa surface et on retire l'élingue.Finally, returning to FIG. 1, it can be seen that the sling 17 has a lifting point 17 a (for example constituted by a ring) which divides this sling into two strands 17 b and 17 c of unequal lengths. The longest strand 17b is in the case of figure, coupled to the ring 16, which implies that the structure is slightly inclined backwards and downwards. In this case, during installation, it is point 35 of the structure which first touches the ground and the effect of gravity acts so as to favor the deployment of the latter. When it is fully deployed (the compasses described above or other members form stops for this deployment), it is lowered completely so that it rests on the ground by its entire surface and the sling is removed.

Pour replier la structure, on accroche le brin long 17b de l'élingue à l'anneau 15. C'est alors le point 35 qui est le premier soulevé puis le coté opposé. L'effet de la pesanteur tend alors à replier la structure, du fait de son inclinaison inverse de celle au sommet du déploiement. Cette disposition est avantageuse, car elle permet de manipuler une structure importante avec un minimum de main d'oeuvre. On conçoit en effet aisément qu'un seul opérateur puisse procéder au chargement ou au déchargement de la structure selon l'in­vention à partir d'un véhicule de transport équipé d'une flèche de levage.To fold the structure, the long strand 17b of the sling is hooked to the ring 15. It is then point 35 which is the first raised then the opposite side. The effect of gravity then tends to fold the structure, due to its inclination opposite to that at the top of the deployment. This arrangement is advantageous because it makes it possible to handle a large structure with a minimum of manpower. It is easily understood that a single operator can load or unload the structure according to the invention from a transport vehicle equipped with a boom lifting.

L'invention trouve une application intéressante dans le domaine des structures démontables à utilisation temporaire.The invention finds an interesting application in the field of removable structures for temporary use.
