Description

La présente invention concerne une structure modulaire pliable pour tente ou abris similaire à montage rapide.The present invention relates to a collapsible modular structure for tent or shelter similar to quick assembly.

L'invention concerne particulièrement les tentes adaptées aux situations d'urgence, et à un usage militaire. Dans ce type particulier d'application, il est souhaité que les tentes aient un relativement faible volume lorsqu'elles sont démontées, et qu'elles puissent être montées et déployées rapidement tout en offrant un abri d'une grande résistance aux conditions météorologiques.The invention particularly relates to tents adapted to emergency situations, and to military use. In this particular type of application, it is desired that the tents have a relatively small volume when disassembled, and that they can be mounted and deployed quickly while providing shelter from a high weather resistance.

De manière générale une tente comprend une structure supportant une toile, ladite structure étant démontable, et constituée à cet effet d'une armature assemblée par emboîtements de profilés tubulaires, qui peuvent aussi être articulés entre eux.In general, a tent comprises a structure supporting a fabric, said structure being removable, and constituted for this purpose an armature assembled by interlocking tubular sections, which can also be hinged together.

On connaît déjà des structures comprenant une succession d'arceaux parallèles, formant des fermes, reliés deux à deux par des barres de jonction qui constituent notamment des pannes. Ces barres de jonction sont assemblées auxdits arceaux par emboîtement et, pour permettre le rapprochement et/ou l'éloignement des arceaux, il est prévu que ces barres soient formées de deux éléments de profilés articulés entre eux et verrouillables en alignement pour former une barre, ou panne, rigide.Structures are already known comprising a succession of parallel arches, forming trusses, connected in pairs by connecting bars which constitute in particular failures. These connecting bars are assembled to said arches by interlocking and, to allow the approximation and / or removal of the arches, it is expected that these bars are formed of two profile elements articulated together and lockable in alignment to form a bar, or failure, rigid.

On connaît notamment, par EP1493886 , une structure modulaire pliable pour tente à montage rapide, constitué de l'assemblage de profilés tubulaires, permettant notamment de former au moins deux arches en vis-à-vis reliées par au moins deux pannes dont une faîtière. Ladite panne faîtière est ici constituée par l'aboutement de deux profilés, par ailleurs solidarisés chacun par leur autre extrémité à une pièce faîtière de chacune desdites arches, ladite extrémité comportant, d'une part, des moyens de pivotement lui permettant de pivoter sur ladite pièce faîtière selon un axe perpendiculaire au plan de l'arche, alors que des moyens d'indexage limitent angulairement ledit pivotement et, d'autre part, des moyens de pivotement permettant l'articulation de ladite extrémité selon un axe transversal, parallèle au plan de l'arche, afin de permettre le repliement dudit profilé parallèlement à ladite arche. L'aboutement des deux profilés de la panne faîtière est réalisé par l'intermédiaire de moyens d'emboîtement aptes à assurer l'immobilisation en pivotement axial d'un profilé par rapport à l'autre selon des positions angulaires de ceux-ci définies par lesdits moyens d'indexage. Une telle structure permet, du fait de la limitation de pivotement, selon un axe perpendiculaire aux plans des arches, de chacun des profilés par rapport aux arches respectives sur lesquelles ils sont liés, et de l'immobilisation en pivotement relatif des deux profilés lors du montage de la structure, d'assurer un maintien fixe en position de la panne faîtière formée par l'assemblage des deux profilés.We know in particular, by EP1493886 , a foldable modular structure for tent quick assembly, consisting of the assembly of tubular profiles, including forming at least two arches vis-à-vis connected by at least two failures including a ridge. Said ridge failure is here constituted by the abutment of two profiles, each further secured by their other end to a ridge piece of each of said arches, said end comprising, on the one hand, pivoting means allowing it to pivot on said ridge piece along an axis perpendicular to the plane of the arch, while means for indexing angularly limit said pivoting and, secondly, pivoting means for the articulation of said end along a transverse axis, parallel to the plane of the arch, to allow the folding of said profile parallel to said arch. The abutment of the two sections of the ridge purlin is produced by means of interlocking means capable of immobilizing, in axial pivoting, one section with respect to the other according to angular positions thereof defined by said indexing means. Such a structure makes it possible, because of the limitation of pivoting, along an axis perpendicular to the planes of the arches, of each of the profiles with respect to the respective arches to which they are connected, and of the immobilization in relative pivoting of the two profiles during the mounting the structure, to ensure a fixed position in the ridge tip position formed by the assembly of the two profiles.

Ce système est assez satisfaisant, bien qu'il nécessite des moyens d'indexage relativement précis pour assurer une bonne immobilisation en pivotement de la panne faîtière, sans gêner les opérations d'aboutement lors du montage de la structure.This system is quite satisfactory, although it requires relatively accurate indexing means to ensure proper immobilization in pivoting the ridge tip, without impeding the abutment operations during assembly of the structure.

Les documents EP 1914364 A2 , EP 2385191 A1 et US 5263507 A montrent d'autres structures de tente repliables.The documents EP 1914364 A2 , EP 2385191 A1 and US 5263507 A show other folding tent structures.

La présente invention a pour but de résoudre les problèmes évoqués ci-dessus, et vise en particulier à proposer une structure modulaire pliable de conception plus simple et robuste que les systèmes antérieurs.The present invention aims to solve the problems mentioned above, and aims in particular to provide a foldable modular structure design simpler and more robust than previous systems.

Avec ces objectifs en vue, l'invention a pour objet une structure modulaire pliable pour tente ou abris similaire à montage rapide, constituée de l'assemblage de profilés, généralement de type tubulaire, et destinée à supporter une toile, lesdits profilés permettant notamment de former au moins deux arches en vis-à-vis reliées par au moins deux pannes dont une panne faîtière,With these objectives in view, the invention relates to a modular structure foldable tent or shelter similar to quick assembly, consisting of the assembly of profiles, generally tubular type, and intended to support a fabric, said profiles allowing in particular to forming at least two arches vis-a-vis connected by at least two failures including a ridge tip,

Selon l'invention, la structure est caractérisée en ce qu'une première extrémité de ladite panne faîtière est liée par une articulation sur une première pièce faîtière que comporte une première desdites arches, ladite articulation comportant, d'une part, des premiers moyens de pivotement permettant le pivotement de ladite panne faîtière selon un axe transversal, parallèle au plan de l'arche, afin de permettre le repliement de la panne parallèlement à ladite arche et, d'autre part, des seconds moyens de pivotement permettant à la panne faîtière de pivoter selon un axe perpendiculaire au plan de l'arche, et la deuxième extrémité de la panne faîtière comporte des moyens de liaison avec une seconde pièce faîtière que comporte une seconde desdites arches, les dits moyens de liaison étant agencés pour assurer une liaison démontable mais rigide entre la panne faîtière et ladite seconde pièce de liaison.According to the invention, the structure is characterized in that a first end of said ridge tip is linked by a hinge on a first ridge piece which comprises a first of said arches, said hinge comprising, on the one hand, first means of pivoting for pivoting said ridge tip along a transverse axis, parallel to the plane of the arch, to allow the folding of the tip parallel to said arch and secondly second pivot means for the ridge failure pivoting along an axis perpendicular to the plane of the arch, and the second end of the ridge purlin has connecting means with a second ridge part that comprises a second of said arches, said connecting means being arranged to provide a removable connection but rigid between the ridge tip and said second connecting piece.

Par liaison démontable mais rigide, on comprend ici une liaison immobilisant la panne faitière sur la seconde pièce de liaison lorsque la structure est montée, en situation d'utilisation, mais séparable lors des opérations de démontage au cours de l'utilisation courante de la structure, c'est à dire lors du démontage de la tente, et cela sans besoin d'outils.By removable but rigid connection, here comprises a connection immobilizing the factoring failure on the second connecting piece when the structure is mounted in use situation, but separable during disassembly operations during the current use of the structure , ie during the dismantling of the tent, and without the need for tools.

Ainsi, lorsque la structure est repliée pour son transport, la panne faîtière peut, grâce à l'articulation à double pivot de sa première extrémité, formant une sorte de rotule, être repliée contre un profilé constitutif de la première arche. Et, lorsque la structure est déployée, la liaison démontable rigide de la deuxième extrémité de la panne faîtière sur la deuxième arche est apte à assurer l'immobilisation de la faîtière, en pivotement selon un axe longitudinal de ladite panne faîtière, par rapport aux arches, et ainsi à assurer le maintien de l'écartement entre les arches tout en garantissant également le positionnement optimal de la panne faîtière pour assurer la meilleure résistance mécanique à la flexion sous les charges auxquelles elle est soumise lors de l'utilisation de la tente.Thus, when the structure is folded for transport, the ridge tip can, thanks to the double pivot joint of its first end, forming a kind of ball joint, be folded against a section constituting the first arch. And, when the structure is deployed, the rigid dismountable connection of the second end of the ridge tip on the second arch is adapted to ensure the immobilization of the ridge, pivoting along a longitudinal axis of said ridge tip, relative to the arches, and thus to Maintain the spacing between the arches while also ensuring the optimal positioning of the ridge tip to ensure the best mechanical resistance to bending under the loads to which it is subjected when using the tent.

Typiquement, la panne faîtière a une section transversale de forme générale rectangulaire, allongée, et la panne faîtière sera donc immobilisée en pivotement dans une position où sa section s'étend verticalement, offrant la meilleure résistance mécanique aux charges verticales.Typically, the ridge tip has a cross section of generally elongated rectangular shape, and the ridge tip will thus be immobilized pivotally in a position where its section extends vertically, providing the best mechanical resistance to vertical loads.

Selon une disposition préférentielle, la panne faîtière est télescopique, ce qui permet de réduire sa longueur pour la placer, en position repliée, contre un des chevrons constituant l'arche, sans excéder la longueur de ce chevron. On notera incidemment que, pour assurer une plus grande compacité de la structure lorsqu'elle est repliée, tout en permettant des grandes dimensions lorsqu'elle est déployée, les dits chevrons pourront aussi être télescopiques. Lorsque la structure est déployée, la panne faîtière est étirée de manière que sa longueur corresponde à l'écartement entre les arches, déterminé par ailleurs par la longueur des autres pannes, comme on le verra par la suite.According to a preferred arrangement, the ridge tip is telescopic, which reduces its length to place it, in the folded position against one of the rafters constituting the arch, without exceeding the length of this chevron. Incidentally, to ensure greater compactness of the structure when folded, while allowing large dimensions when deployed, said rafters may also be telescopic. When the structure is deployed, the ridge tip is stretched so that its length corresponds to the spacing between the arches, also determined by the length of other failures, as will be seen later.

Pour que la panne faîtière soit télescopique comme indiqué ci-dessus, elle comporte préférentiellement deux profilés tubulaires coulissants l'un dans l'autre, et des moyens de verrouillage sont prévus pour verrouiller lesdits profilés coulissants l'un par rapport à l'autre. Ces moyens de verrouillage peuvent être typiquement des verrous par pions, de principe bien connu par ailleurs, montés élastiquement rétractable dans le profilé intérieur, pour pouvoir s'engager, en position allongée de la panne télescopique, dans un trou du profilé extérieur, et verrouiller ainsi les deux profilés en position.For the ridge tip to be telescopic as indicated above, it preferably comprises two tubular profiles sliding one inside the other, and locking means are provided for locking said sliding profiles relative to each other. These locking means can be typically locks per pions, of a principle well known elsewhere, resiliently retractable mounted in the inner profile, to be able to engage, in the extended position of the telescopic tip, in a hole of the outer profile, and thus lock the two profiles in position.

Selon une autre disposition particulière, l'articulation de la panne faîtière sur la première pièce faîtière comporte une chape solidaire de l'extrémité de la panne faîtière montée pivotante sur un tourillon intermédiaire selon un axe parallèle au plan de l'arche, le tourillon intermédiaire étant monté pivotant sur la première pièce faîtière selon un axe perpendiculaire au plan de l'arche. Cette disposition permet d'assurer de manière simple les deux pivotements requis de la panne faîtière par rapport à la première arche.According to another particular arrangement, the articulation of the ridge tip on the first ridge piece comprises a clevis secured to the end of the ridge flange mounted pivotally on an intermediate pin along an axis parallel to the plane of the arch, the intermediate pin being pivotally mounted on the first ridge piece along an axis perpendicular to the plane of the arch. This arrangement makes it possible to ensure in a simple way the two required pivoting of the ridge tip with respect to the first arch.

Selon une autre disposition particulière, les moyens de liaison de la panne faîtière sur la seconde pièce faîtière comportent une douille fixe liée rigidement à la seconde pièce faîtière et ayant un axe vertical, et un tenon solidaire de la seconde extrémité de la panne faîtière, s'étendant perpendiculairement à la direction longitudinale de la panne faîtière et dans la direction longitudinale de la section de celle-ci, et agencé pour s'engager par coulissement vers la bas dans la dite douille.According to another particular arrangement, the connecting means of the ridge tip on the second ridge part comprise a fixed bushing rigidly connected to the second ridge piece and having a vertical axis, and a tenon secured to the second end of the ridge tip, s extending perpendicularly to the longitudinal direction of the ridge tip and in the longitudinal direction of the section thereof, and arranged to slide downwardly into said sleeve.

Lors du déploiement de la structure, il suffit donc d'insérer le tenon dans la dite douille pour assurer à la fois la liaison des deux arches et l'immobilisation de la faîtière en pivotement selon son propre axe longitudinal. Le poids de la faîtière et de la toile de tente supportée par celle-ci est ensuite suffisant pour maintenir en place le tenon dans la douille.During the deployment of the structure, it suffices to insert the pin into said socket to ensure both the connection of the two arches and the immobilization of the ridge pivoting along its own longitudinal axis. The weight of the ridge and the tent fabric supported by it is then sufficient to hold the post in place in the socket.

Selon encore une autre disposition particulière, chacune des arches est constituée d'une pièce faîtière et de deux chevrons, préférentiellement télescopiques, articulés sur ladite pièce faîtière selon des axes distincts et perpendiculaires au plan de l'arche, le pivotement des chevrons étant limité par des butées ménagées sur la dite pièce faîtière. Ces dispositions permettent de replier les chevrons l'un contre l'autre pour le rangement de la structure, et d'assurer ainsi la compacité de la structure repliée.According to yet another particular arrangement, each of the arches consists of a ridge piece and two chevrons, preferably telescopic, articulated on said ridge piece along axes distinct and perpendicular to the plane of the arch, the pivoting of the rafters being limited by stops provided on said ridge piece. These arrangements allow to fold the rafters against each other for the storage of the structure, and thus ensure the compactness of the folded structure.

Préférentiellement aussi, les pièces faitières comportent des moyens de centrage l'une sur l'autre pour les maintenir en position relative lorsque la structure est repliée., ce qui assure le maintien en position relative des pièces faitières et des chevrons tant que la structure n'est pas déployée.Preferably also, the workpieces comprise centering means one on the other to maintain them in relative position when the structure is folded., Which ensures the maintenance in relative position of the parts and ridge chevrons as the structure n is not deployed.

La ou les pannes secondaires qui relient deux arches en complément à la panne faîtière, sont préférentiellement constituées de deux profilés articulés en pivotement d'une part l'un à l'autre et d'autre part à leur arche respective, selon des axes de pivotement parallèles, de manière à permettre le repliement de l'un desdits profilés sur l'autre et donc le rapprochement de deux arches voisines. Les axes de pivotement des profilés sont perpendiculaires à la direction générale des chevrons formant les arches, de sorte que les dits profilés puissent être repliés contre les chevrons et parallèlement à ceux-ci.The secondary fault or failures which connect two arches in addition to the ridge tip, are preferably constituted by two sections pivotally articulated on the one hand to each other and on the other hand to their respective arches, along axes of parallel pivoting, so as to allow the folding of one of said profiles on the other and thus the approximation of two neighboring arches. The pivot axes of the profiles are perpendicular to the general direction of the rafters forming the arches, so that said profiles can be folded against the rafters and parallel thereto.

L'articulation reliant les deux profilés constituant une panne, comporte des moyens de blocage permettant de maintenir lesdits deux profilés alignés après déploiement, les dits moyens de blocage comportant préférentiellement un verrou tubulaire agencé pour coulisser sur les dits profilés et pour pouvoir recouvrir l'articulation et les extrémités des deux profilés adjacentes à la dite articulation, immobilisant ainsi lesdits profilés en alignement.The joint connecting the two sections constituting a failure comprises locking means for maintaining said two sections aligned after deployment, said locking means preferably comprising a tubular lock arranged to slide on said sections and to cover the joint and the ends of the two sections adjacent to said joint, thereby immobilizing said sections in alignment.

D'autres caractéristiques et avantages apparaîtront dans la description qui va être faite d'une structure modulaire pliable pour tente à montage rapide conforme à l'invention.Other features and advantages will appear in the description that will be made of a structure modular collapsible tent for rapid assembly according to the invention.

La structure conforme à l'invention illustrée sur les différentes figures comporte trois arches : deux arches d'extrémités 1 et une arche centrale 2, chacune en forme de V renversé et constituée d'une pièce faîtière 10, 20, sur laquelle s'articulent, selon des axes de pivotement A perpendiculaires au plan de l'arche, deux chevrons respectivement 11 et 12, et 21 et 22. Le pivotement des chevrons sur les pièces faîtières est limité par des butées 101, 201 prévues sur lesdites pièces de manière à assurer l'angle souhaité du V formé par les chevrons.The structure according to the invention illustrated in the various figures comprises three arches: two end arches 1 and a central arch 2, each inverted V-shaped and constituted by a ridge piece 10, 20, on which articulate , along axes of pivoting A perpendicular to the plane of the arch, two rafters respectively 11 and 12, and 21 and 22. The pivoting of the rafters on the ridge pieces is limited by stops 101, 201 provided on said pieces so as to ensure the desired angle of the V formed by the rafters.

Chaque chevron comporte à son extrémité opposée à la pièce faîtière, une pièce d'angle 13, 23 agencée pour y raccorder d'une part les pieds 3, et, d'autre part, les pannes sablières.Each chevron has at its end opposite to the ridge piece, a corner piece 13, 23 arranged to connect on the one hand the feet 3, and on the other hand, the failures sablières.

Les arches 1 et 2 sont reliées par trois pannes, une panne faîtière 4 qui s'étend entre les deux pièces faîtières 10, 20 des arches voisines 1, 2, et deux pannes sablières 5 qui sont raccordées en pivotement également sur les pièces d'angle 13, 23.The arches 1 and 2 are connected by three purlins, a ridge blackout 4 which extends between the two ridge pieces 10, 20 of the neighboring arches 1, 2, and two sandpit faults 5 which are pivotally connected also to the pieces of angle 13, 23.

Les pannes sablières 5 sont constituées de deux profilés 51, 52 articulés en pivotement d'une part l'un par rapport à l'autre et, d'autre part, sur leur arche respective 1,2, selon des axes de pivotement parallèles A1 à A4, comme on le voir figure 3, de manière à permettre le repliement desdits profilés 51,52 l'un sur l'autre et donc le rapprochement et l'écartement de deux arches voisines. Les profilés 51, 52 sont articulés entre eux par l'intermédiaire d'une pièce de liaison 53, que l'on voit mieux figures 4 et 5. Cette pièce de liaison 53, sur laquelle les profilés 51, 52 sont montés pivotants selon les axes A2, A3, parallèles et distants l'un de l'autre de manière à permettre de replier les profilés parallèlement l'un contre l'autre, comporte par ailleurs deux butées 531 agencées pour limiter le pivotement relatif des profilés, dans le sens de l'écartement de ceux-ci, à une position dans laquelle les deux profilés sont en alignement, comme illustré figure 5. Un verrou 54, formé d'un élément tubulaire monté coulissant avec un simple jeu fonctionnel sur un des profilés, peut alors être glissé de manière à recouvrir l'ensemble de la zone d'articulation comportant les extrémités des deux profilés 51, 52 et la pièce de liaison 53, et immobilisé en translation, bloquant ainsi les deux profilés en position alignée, comme on le voit en particulier figure 6.The sill cracks 5 consist of two sections 51, 52 pivotally articulated on the one hand with respect to the other and, on the other hand, on their respective arches 1.2, along parallel pivot axes A1 to A4, as we see figure 3 , so as to allow the folding of said profiles 51,52 one on the other and thus the approximation and spacing of two adjacent arches. The profiles 51, 52 are articulated to each other via a connecting piece 53, which is better seen Figures 4 and 5 . This connecting piece 53, on which the profiles 51, 52 are pivotally mounted along the axes A2, A3, parallel and spaced from each other so as to allow folding the profiles parallel to each other, further comprises two stops 531 arranged to limit the relative pivoting of the profiles, in the direction of the spacing thereof, at a position in which the two sections are in alignment, as illustrated figure 5 . A latch 54, formed of a tubular element slidably mounted with a simple functional clearance on one of the profiles, can then be slid so as to cover the whole of the articulation zone comprising the ends of the two sections 51, 52 and the connecting piece 53, and immobilized in translation, thus blocking the two profiles in aligned position, as seen in particular figure 6 .

On notera aussi que les axes de pivotement A1 et A4 des deux profilés sur les pièces d'angle 13, 23 sont orthogonaux aux chevrons 11,12, 21, 22, de sorte que, en position replié, les profilé soient repliés contre lesdits chevrons, parallèlement à ceux-ci, comme représenté figures 1 et 2.Note also that the pivot axes A1 and A4 of the two sections on the corner pieces 13, 23 are orthogonal to the rafters 11, 12, 21, 22, so that, in the folded position, the profiles are folded against said rafters , parallel to these, as shown Figures 1 and 2 .

La panne faîtière 4 est constituée de deux profilés 41, 42 de section générale rectangulaire, coulissant l'un dans l'autre de manière que la panne faîtière soit télescopique ; et comporte des moyens de verrouillage des deux profilés 41, 42 tant en position rétractée, pour maintenir la panne faîtière dans cette position rétractée lorsque la structure est repliée, que en position étendue, lorsque la panne faîtière relie les deux arches 1, 2. Ces moyens de verrouillage peuvent notamment être des verrous à pions 43, de type connu en soi pour verrouiller des éléments télescopiques coulissants.The ridge tip 4 consists of two sections 41, 42 of rectangular general section, sliding one inside the other so that the ridge tip is telescopic; and comprises locking means of the two sections 41, 42 both in the retracted position, to maintain the ridge tip in this retracted position when the structure is folded, than in the extended position, when the ridge tip connects the two arches 1, 2. These locking means may in particular be pawl locks 43, of a type known per se for locking sliding telescopic elements.

La panne faîtière 4 est articulée par une extrémité sur une première arche, par exemple l'arche 1, au moyen d'un système d'articulation 6 à axes concourants, permettant d'une part de faire pivoter la panne faîtière 4 par rapport à l'arche 1 selon un axe A5 parallèle au plan de ladite arche, et selon un axe A6 orthogonal au dit plan de l'arche, ce qui permet d'amener la panne faîtière contre l'un des chevrons 11, 12 lorsque la structure est repliée, et, alternativement, lorsque la structure est déployée, de placer la dite panne 4 perpendiculairement au plan de l'arche 1, pour y relier la seconde arche 2, le pivotement selon l'axe A6 permettant de positionner la panne faîtière 4 dans la position où elle présente la meilleure résistance à des charges verticales, c'est à dire avec sa section rectangulaire, et donc l'axe A5, orientée verticalement. Le système d'articulation 6 comporte typiquement un tourillon 61 monté pivotant selon l'axe A6 sur la pièce faîtière 10, et l'extrémité de la panne faîtière 4 comporte une chape 44 montée pivotante sur ledit tourillon selon l'axe A5.The ridge tip 4 is hinged at one end to a first arch, for example the arch 1, by means of a hinge system 6 with concurrent axes, making it possible on the one hand to pivot the ridge tip 4 with respect to the arch 1 along an axis A5 parallel to the plane of said arch, and along an axis A6 orthogonal to said plane of the arch, which allows to bring the ridge tip against one of the rafters 11, 12 when the structure is folded, and, alternatively, when the structure is deployed, to place the said tip 4 perpendicular to the plane of the arch 1, to connect the second arch 2, the pivoting along the axis A6 for positioning the ridge tip 4 in the position where it has the best resistance at vertical loads, ie with its rectangular section, and therefore the axis A5, oriented vertically. The hinge system 6 typically comprises a pin 61 pivotally mounted along the axis A6 on the ridge piece 10, and the end of the ridge tip 4 comprises a yoke 44 pivotally mounted on said pin along the axis A5.

La panne faîtière 4 comprend à son autre extrémité une pièce d'accrochage 45 comportant un tenon 46 qui s'étend perpendiculairement à la panne faîtière et orienté selon la plus grande dimension de la section de ladite panne, c'est à dire parallèlement à l'axe A5. Le tenon est par ailleurs dimensionné pour s'engager par coulissement vertical, comme illustré figure 11, dans une douille 25 liée rigidement à la pièce faîtière 20 et dont l'axe A7 est vertical lorsque la structure est montée. La douille fixe 25 peut être réalisée d'une pièce avec la pièce faîtière 20. Ainsi lorsque le tenon 46 est emmanché dans la douille 25, d'une part la panne faîtière relie rigidement les deux pièces faîtières 10, 20, et d'autre part ledit emmanchement empêche la panne faîtière de pivoter selon son axe longitudinal, assurant ainsi son maintien dans la position optimale pour la résistance de la structure.The ridge tip 4 comprises at its other end a hooking piece 45 comprising a pin 46 which extends perpendicular to the ridge tip and oriented along the largest dimension of the section of said tip, that is to say parallel to the axis A5. The tenon is also dimensioned to engage by vertical sliding, as illustrated figure 11 in a socket 25 rigidly connected to the ridge piece 20 and whose axis A7 is vertical when the structure is mounted. The fixed sleeve 25 can be made in one piece with the ridge piece 20. Thus when the pin 46 is fitted into the sleeve 25, firstly the ridge tip rigidly connects the two ridge parts 10, 20, and other Apart from said fitting prevents the ridge tip to pivot along its longitudinal axis, thus ensuring its maintenance in the optimal position for the strength of the structure.

Par ailleurs, la douille fixe 25 porte un téton de centrage 251, s'étendant orthogonalement à l'axe A7 et au plan général de la pièce faitière 20, et de dimensions adaptées pour pouvoir s'engager dans un trou 611 ménagé à cet effet dans le tourillon 61, lorsque la structure est repliée, les pièces faitières 10 et 20 étant l'une contre l'autre, comme représenté sur la figure 1. Ainsi, lors de la première phase du dépliage de la structure, illustrée par la figure 2, les différentes pièces faitières restent positionnées en alignement, évitant qu'elles se déplacent l'une sur l'autre ce qui pourrait amener les différents éléments de la structure à de déplacer respectivement de manière incontrôlée. Grâce à ce système de centrage entre les différentes pièces faitières, on facilite donc notablement le déploiement et le montage de la structure. On pourrait aussi de manière tout à fait équivalente former le téton de centrage sur le tourillon 61, coopérant avec un trou réalisé dans la douille fixe.Moreover, the fixed sleeve 25 carries a centering stud 251, extending orthogonally to the axis A7 and to the general plane of the part-die 20, and of suitable dimensions to be able to engage in a hole 611 provided for this purpose in the trunnion 61, when the structure is folded, the pieces 10 and 20 being against each other, as shown in FIG. figure 1 . So, when the first phase of unfolding the structure, illustrated by the figure 2 , the different pieces still remain positioned in alignment, avoiding that they move on one another which could cause the various elements of the structure to move respectively uncontrollably. Thanks to this system of centering between the different parts ridge, thus significantly facilitates the deployment and assembly of the structure. It would also be quite equivalent to form the centering pin on the pin 61, cooperating with a hole in the fixed sleeve.

Le montage de la structure s'effectue comme suit : partant de la position repliée de la structure représentée figure 1, on commence par déployer les chevrons 11,12, 21, 22 par pivotement sur les pièces faîtières 10, 20, selon les flèches F1, jusqu'à amener les chevrons contre les butées 101, 201, dans la position représentée figure 2, les pièces faitières étant alors maintenues en place les unes par rapport aux autres par les tétons 251 engagés dans les trous 611.The assembly of the structure is as follows: starting from the folded position of the structure shown figure 1 , the chevrons 11, 12, 21, 22 are first deployed by pivoting on the ridge pieces 10, 20, according to the arrows F1, until the chevrons are brought against the stops 101, 201, in the position shown figure 2 , the pieces are then maintained in place relative to each other by the pins 251 engaged in the holes 611.

On continue à déployer la structure en écartant les arches 1, 2, comme représenté par les flèches F2 figure 3, cet écartement s'accompagnant du pivotement, selon les flèches F3, des profilés 51, 52 constituant les pannes sablières 5, jusqu'à ce que lesdits profilés soient en alignement, cet alignement étant par ailleurs assuré par la venue en butée desdits profilés contre les butées 531 des pièces de liaison 53. Les verrous 54 sont alors amenés par coulissement, selon la flèche F4, jusqu'à solidariser les profilés 51, 52 entre eux, dans la dite position alignée.We continue to deploy the structure by spreading the arches 1, 2, as represented by the arrows F2 figure 3 , this spacing being accompanied by the pivoting, according to the arrows F3, profiles 51, 52 constituting the purlins faults 5, until said profiles are in alignment, this alignment being further ensured by the abutment of said profiles against the stops 531 of the connecting pieces 53. The locks 54 are then slidably guided along the arrow F4 until the sections 51, 52 are joined together in the said aligned position.

La panne faîtière 4, qui était jusque là restée accolée contre un chevron, est déployée par un pivotement autour de l'axe A5, selon la flèche F5, et un pivotement sur elle-même autour de l'axe A6 selon la flèche F6, pour amener la panne faîtière perpendiculaire au plan de l'arche 1, sa section s'étendant verticalement. La panne faîtière est allongée par coulissement relatif, selon la flèche F7, des profilés 41, 42 qui la constitue, jusqu'au verrouillage relatif de ces profilés dan la position d'extension de la panne faîtière, dont la seconde extrémité est alors raccordée sur la pièce faîtière 20 de la deuxième arche, par engagement du tenon 46 dans la douille 25.The ridge tip 4, which hitherto remained contiguous against a chevron, is deployed by pivoting about the axis A5, according to the arrow F5, and pivoting on itself about the axis A6 according to the arrow F6, to bring the ridge tip perpendicular to the plane of arch 1, its section extending vertically. The ridge tip is elongated by relative sliding, according to the arrow F7, of the profiles 41, 42 which constitutes it, until the relative locking of these profiles dan the extension position of the ridge tip, whose second end is then connected to the ridge piece 20 of the second arch, by engagement of the pin 46 in the sleeve 25.

La structure se trouve alors à l'état illustré figure 13. Si les chevrons sont également télescopiques, on les amène alors dans leur position d'extension, puis on raccorde les pieds 3 sur les pièces d'angle 13 et 23 pour terminer le montage de la structure, prêt à recevoir la toile de tente.The structure is then in the illustrated state figure 13 . If the rafters are also telescopic, they are then brought into their extended position, then the feet 3 are connected to the corner pieces 13 and 23 to complete the assembly of the structure, ready to receive the tent.

Le repliage de la structure s'effectue bien entendu par la démarche inverse au montage.The folding of the structure is of course carried out by the opposite approach to assembly.

Le nombre d'arches de la structure présentée dans l'exemple qui vient d'être décrit est de trois, mais on pourra bien sûr utiliser le même système pour des structures avec deux arches ou avec plus de trois arches.The number of arches of the structure presented in the example just described is three, but we can of course use the same system for structures with two arches or with more than three arches.

Des pannes secondaires intermédiaires pourraient aussi être utilisées, pour renforcer le soutien de la toile, placées entre la panne faîtière et les pannes sablières.Intermediate secondary faults could also be used, to reinforce the support of the fabric, placed between the ridge tip and the sandpit faults.

Dans des structures similaires, il serait aussi possible de réaliser les pannes autres que la panne faîtière, ou au moins certaines des autres pannes, de manière similaire à ce qui a été dit précédemment pour la panne faîtière.In similar structures, it would also be possible to perform failures other than the ridge failure, or at least some of the other failures, similar to what was said earlier for the ridge tip.

Les chevrons 11, 12, 21, 22, pourront aussi être télescopiques, pour augmenter la largeur de la structure déployée tout en gardant un encombrement réduit de la structure repliée. Dans ce cas, on pourra aussi utiliser comme moyens de verrouillage des chevrons en position déployée, et en position rétractée, des verrous à pions similaires au verrou 43 de la panne faitière, ou d'autres verrous de type connu pour verrouiller des éléments télescopiques coulissants.The rafters 11, 12, 21, 22 may also be telescopic, to increase the width of the deployed structure while keeping a small footprint of the folded structure. In this case, it will also be possible to use as locks chevrons in the deployed position, and in the retracted position, pawl locks similar to latch 43 of the blackout, or other locks of known type to lock sliding telescopic elements.

Bien que préférentiellement les profilés utilisés ont une section de forme générale rectangulaire, en général optimale pour des raisons de résistance mécanique, on pourra aussi utiliser des profilés d'autre section, dans la mesure où, pour les éléments télescopiques au moins, ils pourront coulisser les uns dans les autres sans possibilité de pivotement relatif selon leur direction longitudinale.Although preferably the profiles used have a section of generally rectangular shape, generally optimal for reasons of mechanical strength, it will also be possible to use profiles of other section, insofar as, for the telescopic elements at least, they will be able to slide in each other without possibility of relative pivoting in their longitudinal direction.
