Description

Abri detoile Shelter
La présente invention concerne le domaine des constructions provisoires ou du moins légères, de grande envergure, destinées à former des abris, en général temporaires, pour couvrir au moyen d'une toile supérieure une zone au sol circonscrite par une structure périphérique porteuse de la toile.The present invention relates to the field of temporary constructions or at least light, large-scale, intended to form shelters, usually temporary, to cover by means of an upper canvas a ground area circumscribed by a peripheral structure carrying the canvas .
ARRIERE PLAN DE L'INVENTION On entend par grande envergure l'abri dont un diamètre (ou la grande dimension transversale de son enceinte) est au minimum de l'ordre de dix mètres, bien que cette indication soit donnée à titre non limitatif. Des envergures plus petites peuvent en effet être recouvertes par d'autres moyens et avec des structures concurrentes de celles de l'invention tant au plan de leur simplicité technique de conception et de mise en œuvre que de leur coût, du fait même de leur taille réduite. L'intérêt de l'invention n'est réellement patent qu'au-delà de cette taille.BACKGROUND OF THE INVENTION Large span means shelter whose diameter (or large transverse dimension of its enclosure) is at least of the order of ten meters, although this indication is given in a non-limiting manner. Smaller spans can indeed be covered by other means and structures competing with those of the invention both in terms of their technical simplicity of design and implementation and their cost, because of their size. scaled down. The interest of the invention is really patent only beyond this size.
Par la suite, on parlera d'abri temporaire, pour désigner de manière globale la structure et sa couverture .Subsequently, we will speak of temporary shelter, to designate in a global way the structure and its cover.
De tels abris temporaires trouvent de nombreuses applications telles que, par exemple, la protection de périmètres sanitaires, la couverture d'aires de spectacles, de manifestations, de fouilles ou de recherches archéologiques, de chantiers de plein-air...Such temporary shelters have many applications such as, for example, the protection of sanitary perimeters, the coverage of performance areas, events, excavations or archaeological research, outdoor sites ...
Il existe de nombreux abris comportant principa- lement une structure porteuse à base de tubes ou d'éléments allongés métalliques et une toile formant un toit ou un auvent, de même que des parois latérales attachées à cette structure. La structure porteuse est souvent démontable lorsque l'abri est de petites dimensions. Sur ce modèle, il n'existe pas de grandes structures temporaires sauf à ce que celles-ci soient la juxtaposition de plusieurs structures de petites dimensions. En outre, le toit de ces abris est très souvent tendu ou placé sur une charpente (également repliable ou démontable) qui fait partie de la structure et qui participe à l'obtention de sa stabilité.There are numerous shelters mainly comprising a support structure based on tubes or elongated metal elements and a roof-forming fabric or awning, as well as sidewalls attached to this structure. The supporting structure is often removable when the shelter is small. On this model, there are no large temporary structures except that these are the juxtaposition of several small structures. In addition, the roof of these shelters is often stretched or placed on a frame (also collapsible or dismountable) which is part of the structure and involved in obtaining its stability.
On connaît également pour la couverture de grandes surfaces telles que des piscines, des terrains de sport ou des serres agricoles..., des structures gonflables dans lesquelles est entretenue une surpression qui permet de maintenir tendue une toile de couverture (généralement en forme de demi-sphère ou demi-cylindre) dont les bords sont arrimés au sol .It is also known for the coverage of large areas such as swimming pools, sports fields or agricultural greenhouses, inflatable structures in which is maintained an overpressure that keeps a tense cover (generally half-shaped) -sphere or half-cylinder) whose edges are lashed to the ground.
On connaît aussi les chapiteaux de cirque dont l'érection et le démontage sont fréquents. Ceux-ci présentent en général une structure de portique qui supporte une toile intérieure fixée au sol en partie basse. Certaines structures présentent des poteaux latéraux haubanés . OBJET DE L'INVENTIONThere are also circus capitals, which are often erected and dismantled. These generally have a gantry structure that supports an inner fabric fixed to the ground at the bottom. Some structures have guyed side columns. OBJECT OF THE INVENTION
La présente invention entend proposer une nouvelle conception d'abri temporaire dont la structure porteuse est d'une grande simplicité, de sorte qu'elle est aisée à ériger, le toit qui lui est associé pouvant pré- senter différentes formes de réalisation.The present invention intends to propose a new design of temporary shelter whose carrier structure is of great simplicity, so that it is easy to erect, the roof associated with it may present different embodiments.
RESUME DE L'INVENTIONSUMMARY OF THE INVENTION
A cet effet donc, l'invention a pour objet un abri de toile comportant une structure de support et une toile formant au moins couverture partielle d'une aire située à l'intérieur de la structure, dans laquelle, la structure de support comporte une ossature latérale comprenant une pluralité de mâts verticaux et une ceinture fermée horizontale indéformable par laquelle chaque mât est associé à chacun de ses voisins, pour s'opposer aux efforts centripètes auxquels est soumise l'ossature et un moyen central d'accrochage de la toile maintenu en hauteur par des suspentes radiales filaires issues de l'ossature, la toile étant radialement maintenue entre ledit moyen central et l'ossature périphérique. Le maintien radial doit se comprendre comme une tension radiale appliquée à la toile depuis l'ossature, d'une valeur plu ou moins forte, cette tension étant reprise dans la toile par des rubans ou câbles de renfort insérés . Dans un premier mode de réalisation, le moyen d'accrochage est situé au point de convergence d'un ensemble de filins radiaux formant les suspentes susdites.For this purpose therefore, the subject of the invention is a canvas shelter comprising a support structure and a fabric forming at least partial coverage of an area situated inside the structure, in which the support structure comprises a lateral frame comprising a plurality of vertical poles and a horizontal non-deformable closed belt by which each mast is associated with each of its neighbors, to oppose the centripetal forces to which the framework is subjected and a central means of attachment of the fabric held in height by wire radial lines derived from the frame, the web being radially held between said central means and the peripheral frame. The radial support must be understood as a radial tension applied to the web from the frame, of a greater or lesser value, this tension being taken up in the fabric by inserted reinforcing ribbons or cables. In a first embodiment, the attachment means is located at the point of convergence of a set of radial ropes forming the aforesaid lines.
Dans un second mode de réalisation, le moyen d'accrochage comporte un anneau relié aux suspentes sus- dites et présentant une pluralité de moyens de fixation de la toile susdite qui constitue une couverture annulaire .In a second embodiment, the attachment means comprises a ring connected to the above suspensions and having a plurality of fastening means of the aforesaid web which constitutes an annular cover.
Avantageusement, la ceinture comporte plusieurs poutres s 'étendant entre deux mâts adjacents et des ti- rants qui s'étendent entre deux mâts séparés par au moins un autre mât .Advantageously, the belt comprises a plurality of beams extending between two adjacent poles and springs which extend between two poles separated by at least one other mast.
Plusieurs variantes du mode de réalisation de cette ceinture sont possibles. L'une d'elles, dans laquelle les tirants sont formés par des câbles, comporte en plus, au droit de chaque poteau une fiche d'écartement du câble pour tenir compte du grand rayon de courbure de l'ossature périphérique ayant pour conséquence une interférence entre chaque câble et le mât intermédiaire.Several variants of the embodiment of this belt are possible. One of these, in which the tie rods are formed by cables, further comprises, at the right of each post a cable spacer to take into account the large radius of curvature of the peripheral frame resulting in a interference between each cable and the intermediate mast.
Chaque suspente est de préférence associée à cha- que mât par un treuil de manœuvre.Each line is preferably associated with each mast by a maneuvering winch.
Dans le cas d'une couverture annulaire troussable vers l'ossature périphérique, la toile est formée par un tube de circonférence sensiblement égal à la longueur de la périphérie de l'aire à couvrir et de longueur égale à la largeur d'une zone annulaire à couvrir à l'intérieur de la périphérie, cette toile étant équipée sur l'un de ses bords d'une pluralité de filins de déploiement en nombre égal au nombre des mâts de l'ossature, l'autre bord de la toile étant fixé à l'ossature, chacun des fi- lins de déploiement de la toile passant dans un organe de renvoi porté par l'anneau d'accrochage tandis que plusieurs filins coopérant au repliement de la toile, chacun d'eux possédant deux brins l'un au dessus et l'autre au dessous de la toile, avec deux extrémités dont l'une est fixée à l'ossature périphérique et l'autre à un treuil d'enroulement/déroulement solidaire de cette ossature, chaque filin de repliement étant guidé au bord de la toile équipé du filin de déploiement dans un organe de son coulissement sur ce bord de toile. Dans une variante non représentée de l'invention, chacun des filins coopérant au repliement de la toile et solidaire du bord de toile auquel est attaché chaque filin de déploiement par une partie médiane, les deux brins ainsi définis, l'un dessus et l'autre dessous la toile, passant sur des poulies de renvoi portées par l'ossature périphérique et aboutissant à un treuil commun d'enroulement/déroulement. Le troussage de la toile est ainsi amélioré car il faut n'enrouler qu'une demi longueur de filin par rapport à la réalisation précédemment évoquée.In the case of an annular cover troussable towards the peripheral framework, the fabric is formed by a tube of circumference substantially equal to the length of the periphery of the area to be covered and of length equal to the width of an annular zone to cover inside from the periphery, this fabric being equipped on one of its edges with a plurality of deployment cables in number equal to the number of masts of the frame, the other edge of the fabric being fixed to the frame, each rolls of deployment of the cloth passing through a return member carried by the hooking ring while several threads cooperating with the folding of the cloth, each of them having two strands one above and the other below the fabric, with two ends, one of which is fixed to the peripheral framework and the other to a winding winding / unrestrained winch of this framework, each fold line being guided to the edge of the fabric equipped with deployment rope in an organ of its sliding on this edge of canvas. In a variant not shown of the invention, each of the ropes cooperating with the folding of the fabric and secured to the edge of the fabric to which each deployment line is attached by a median part, the two strands thus defined, the one above and the other below the canvas, passing on pulleys carried by the peripheral frame and ending in a common winch winding / unwinding. The troussage of the fabric is thus improved because it is necessary to wind a half length of rope compared to the previously mentioned embodiment.
L'abri selon l'invention, dans sa version à couverture partielle peut trouver une application intéressante dans la couverture de zones annulaires telles que des tribunes d'un amphithéâtre ou d'une arène, quelle que soit la forme de la périphérie de cette zone annulaire. Cette couverture peut être utilisée avantageusement au- dessus d'un théâtre ruiné, c'est-à-dire dont les murs extérieurs ne possèdent plus les éléments nécessaires à la mise en place, comme à l'origine, des mâts destinés à la suspente des vélums. Dans ce cas d'application, la ceinture peut comprendre une partie en maçonnerie subsistante, de l'ouvrage partiellement ruiné.The shelter according to the invention, in its partial coverage version can find an interesting application in the coverage of annular areas such as stands of an amphitheater or arena, whatever the shape of the periphery of this area annular. This cover can be used advantageously above a ruined theater, that is to say whose outer walls no longer have the elements necessary for the establishment, as originally, of the masts for the hanger awnings. In this case of application, the belt may comprise a portion of remaining masonry, partially ruined work.
Une caractéristique d'une telle couverture annu- laire est que son bord intérieur, lorsque la couverture est déployée, festonne entre chacun des organes de renvoi portés par l'anneau de la structure de soutien.A feature of such annular cover is that its inner edge, when the cover is deployed, scallops between each of the return members carried by the ring of the support structure.
Dans une variante de réalisation, la toile est formée par la juxtaposition d'une pluralité d'auvents in- dépendants, chacun d'eux étant troussable vers l'ossature périphérique et étant fixé par l'un de ses bords à cette ossature alors que sur son autre bord, parallèle à celui fixé à l'ossature, il est équipé d'une pluralité de filins de dépliement en nombre égal au nombre de mâts de l'ossature embrassés par le bord susdit de fixation, chacun des filins de déploiement de l'auvent passant dans un organe de renvoi porté par l'anneau d'accrochage tandis que plusieurs filins coopèrent au repliement de l'auvent, chacun d'eux possédant deux brins l'un au dessus et l'autre au dessous de l'auvent, avec deux extrémités dont l'une est fixée à l'ossature périphérique et l'autre à un treuil d' enroulement/déroulement solidaire de cette ossature, chaque filin de repliement étant guidé au bord de l'auvent équipé du filin de déploiement dans un organe de son coulissement sur ce bord. En variante, comme précédemment, chaque filin de repliement d'auvent peut être associé à un treuil unique d'enroulement/déroulement.In an alternative embodiment, the fabric is formed by the juxtaposition of a plurality of independent awnings, each of them being troussable towards the peripheral framework and being fixed by one of its edges to this framework while on its other edge, parallel to that fixed to the frame, it is equipped with a plurality of expansion lines in number equal to the number of masts of the frame embraced by the above-mentioned fastening edge, each of the deployment lines of the awning passing in a return member carried by the snap ring while several ropes cooperate to the folding of the awning, each of them having two strands one above and one below the awning, with two ends, one of which is fixed to the peripheral framework and the other to a winding winding / unrestrained winch of this framework, each fold line being guided to the edge of the awning equipped with the deployment line in an organ of his couli on this edge. Alternatively, as before, each awning folding rope may be associated with a single winding / unwinding winch.
Chaque auvent sera de forme rectangulaire possédant un feston sur son bord le plus au centre de l'aire recouverte lorsqu'il est déployé ou de forme trapézoïdale, le feston central pouvant alors ne pas exister ou être très peu prononcé.Each awning will be rectangular in shape with a festoon on its most central edge of the covered area when deployed or trapezoidal shape, the central festoon may then not exist or be very little pronounced.

DESCRIPTION DETAILLEE DE L'INVENTION L'abri temporaire selon l'invention représenté schématiquement aux trois premières figures possède une ossature latérale 1 formée d'une pluralité de mâts régulièrement répartis à la périphérie d'une aire au sol 2 qu'il convient d'abriter ou de couvrir, cette périphérie étant dans le cas de figure circulaire. Seuls sont représentés deux mâts opposés la et Ib de l'ossature périphérique 1. Ces mâts possèdent une semelle 3 d'appui au sol et sont reliés ici à peu près à mi-hauteur par une ceinture 4 formée ici par un jeu d' entretoises qui sera dé- crit plus en détail dans la suite de la présente description. On notera d'ores et déjà que cette ceinture 4 constituent avantageusement soit une passerelle de service permettant à des opérateurs de circuler sur l'ossature latérale, soit le support d'une passerelle qui pourrait par exemple s'étendre horizontalement à l'extérieur et/ou à l'intérieur de cette ossature latérale.FIG. 7 is a longitudinal cross-sectional view of one of the masts of this framework at the waist, FIG. 8 is a view of a mast in cross-section along the line VIII-VIII of FIG. DETAILED DESCRIPTION OF THE INVENTION The temporary shelter according to the invention shown schematically in the first three figures has a lateral frame 1 formed of a plurality of regularly distributed masts at the periphery of a floor area 2 which is suitable for use. to shelter or to cover, this periphery being in the case of circular figure. Only two opposing poles 1a and 1b of the peripheral framework 1 are represented. These poles have a ground support sole 3 and are connected here at approximately mid-height by a belt 4 formed here by a set of spacers. which will be described in more detail later in this description. It should already be noted that this belt 4 advantageously constitutes either a service bridge allowing operators to circulate on the lateral framework, or the support of a bridge which could for example extend horizontally outside and /or inside this lateral framework.
La partie supérieure de chaque mât possède un système de renvoi, poulie ou autre dans lequel passe une pluralité de cordes, câbles ou filins 5a, 5b, appelées suspentes, en nombre égal au nombre de mâts. Ces suspentes sont réunies au centre en un point de convergence 6 pourvu d'un moyen d'accrochage d'une toile. A ce point, une toile de couverture, ici en forme de disque par exemple 7, est attachée à la pluralité des suspentes 5. Une fois l'érection de l'ossature latérale réalisée, les opérateurs étendent au sol 2 la toile 7 et disposent chacune des suspentes 5a, 5b de levage en forme d'araignée comme représenté à la figure 1. La pluralité des suspentes est ensuite levée au moyen de tout système de levage motorisé ou manuel solidaire de chacun des mâts, de manière à tendre ces suspentes pour en faire la structure de soutien du centre de la toile 7. Cette disposition est représentée à la figure 2.The upper part of each mast has a return system, pulley or other in which passes a plurality of ropes, cables or cables 5a, 5b, called lines, in number equal to the number of poles. These lines are brought together in the center at a point of convergence 6 provided with a means for attaching a canvas. At this point, a cover fabric, here disk-shaped for example 7, is attached to the plurality of lines 5. Once the erection of the lateral frame realized, the operators extend to the floor 2 the canvas 7 and have each of the suspension lines 5a, 5b spider-shaped as shown in Figure 1. The plurality of lines is then lifted by means of any powered or manual lifting system secured to each of the poles, so as to stretch these lines for make it the supporting structure of the center of the canvas 7. This arrangement is shown in Figure 2.
Des cordes ou filins telles que 8a, 8b, sont is- sues de la périphérie de la toile et sont en nombre égal au nombre de mâts de l'ossature latérale. Ces cordes sont de préférence formées par des extrémités libres de bandes, rubans ou cordes, éléments linéaires de renfort insérés dans la toile jusque vers son centre. Au moyen de ces cordes dont celles 8a, 8b, les opérateurs procèdent à la tension de la toile pour obtenir le résultat illustré schématiquement par la figure 3.Ropes or ropes such as 8a, 8b are made from the periphery of the fabric and are equal in number to the number of masts of the lateral framework. These cords are preferably formed by free ends of strips, ribbons or ropes, linear reinforcing elements inserted in the fabric to its center. By means of these cords including those 8a, 8b, the operators proceed to the tension of the fabric to obtain the result illustrated schematically in FIG.
La vue de dessus de l'abri réalisé est représentée à la figure 4. On y retrouve l'ossature périphérique 1 avec ses mâts tels que la et Ib, la toile 7 et, superposées, l'une cachant l'autre, les suspentes telles que 5a. et 5b et les cordes insérées 8a et 8b.The top view of the shelter made is shown in Figure 4. It includes the peripheral frame 1 with its masts such as and Ib, the canvas 7 and, superimposed, one hiding the other, the lines such as 5a. and 5b and inserted strings 8a and 8b.
A la figure 5, où certains des éléments représentés sont déjà décrits en regard des figures précédentes avec les mêmes références, chacune des suspentes 5, au lieu de converger en un point 6, est attachée à un anneau central 50 qui délimitera l'aire centrale non couverte par la toile annulaire de l'abri selon l'invention. Selon la taille de cet abri et selon la puissance des moyens motorisés ou non mis en œuvre pour élever l'anneau 50, cet anneau 50 peut être réalisé par plusieurs anneaux à chacun desquels n'est affectée qu'une partie des suspentes de levage .In Figure 5, where some of the elements shown are already described with reference to the preceding figures with the same references, each of the lines 5, at instead of converging at a point 6, is attached to a central ring 50 which will delimit the central area not covered by the annular web of the shelter according to the invention. Depending on the size of this shelter and the power of the motorized means or not implemented to raise the ring 50, this ring 50 can be achieved by several rings to each of which is assigned only part of the lifting lines.
L'anneau 50 comporte des organes de renvoi 51 (une poulie ou une simple boucle métallique) , pour des filins 52 solidaires du bord intérieur 53 d'une toile 54 annulaire. En réalité, cette toile annulaire 54 est une toile tubulaire dont les deux bords d'extrémité 53 et 55 ont la même dimension, de sorte qu'elle peut être trous- sée en rapprochant le bord 53 du bord 55 ou déployée en éloignant ce bord 53 du bord 55. Dans l'état déployé de la toile, le bord 53 qui est proche de l'anneau 50 festonne compte tenu de l'excédent de longueur de la toile par rapport à la dimension périphérique de l'anneau 50. Le bord 55 de la toile 54 est solidaire de la structure périphérique tandis que l'extrémité libre de chaque filin 52 est enroulée sur un treuil 56 manoeuvrable de manière manuelle ou motorisée. Des filins 57 possèdent un brin 57a situé sous la toile et un brin 57b si- tué au-dessus de cette toile. Les deux brins sont bien entendu les parties d'un filin continu qui contourne le bord 53 de la toile 54 en pouvant coulisser par rapport à ce bord dans un guide approprié comme par exemple un anneau. L'extrémité libre du brin 57a est solidaire de l'ossature latérale tandis que l'extrémité libre du brin 57b est accrochée au tambour d'un treuil 58 de manœuvre du repliement de la toile. Le filin 57 peut être fixé par son milieu au bord de toile 53 et ses deux extrémités libres associées à un treuil unique d'enroulement /déroulement, passage sur un organe de renvoi porté par l'ossature périphérique. Cette variante n'est pas représentéeThe ring 50 has return members 51 (a pulley or a simple metal loop), for the ropes 52 integral with the inner edge 53 of an annular web 54. In reality, this annular web 54 is a tubular web whose two end edges 53 and 55 have the same dimension, so that it can be punctured by bringing the edge 53 of the edge 55 or deployed closer together by moving this edge away. 53 of the edge 55. In the deployed state of the fabric, the edge 53 which is close to the ring 50 festooning given the excess length of the fabric relative to the peripheral dimension of the ring 50. edge 55 of the fabric 54 is integral with the peripheral structure while the free end of each rope 52 is wound on a winch 56 operable manually or motorized. Cords 57 have a strand 57a located under the fabric and a strand 57b above said fabric. The two strands are of course the parts of a continuous rope which bypasses the edge 53 of the fabric 54 being slidable with respect to this edge in a suitable guide such as a ring. The free end of the strand 57a is secured to the lateral frame while the free end of the strand 57b is attached to the drum of a winch 58 to maneuver the folding of the fabric. The rope 57 can be fixed by its middle to the edge of fabric 53 and its two free ends associated with a single winch winding / unwinding, passage on a return member carried by the peripheral framework. This variant is not represented
On supposera la toile troussée, c'est-à-dire le bord 53 de celle-ci au voisinage du bord 55 reposant sur une plate-forme de service 59 solidaire de l'ossature 1. L'anneau 50 est au sol et les filins 52 passent autour de des organes de renvoi 51. Les suspentes 5 sont chacune attelées à un treuil 26 en passant sur un organe de renvoi 25. On procède au levage de l'anneau 50 en actionnant tous les treuils 26. Cet anneau étant en place, on peut ensuite procéder au déploiement de la toile 54 en actionnant chacun des treuils 56 pour enrouler les filins 52. Dans ce mouvement, les filins 57 se déroulent des treuils 58 et les brins 57a et 57b de chacun d'eux s'étendent de chaque côté de la toile.It is assumed that the curved fabric, that is to say the edge 53 thereof in the vicinity of the edge 55 resting on a service platform 59 secured to the frame 1. The ring 50 is on the ground and the The lines 5 are each connected to a winch 26 by passing over a deflection member 25. The ring 50 is lifted by actuating all the winches 26. This ring being place, can then proceed to the deployment of the fabric 54 by actuating each of the winches 56 to wind the ropes 52. In this movement, the ropes 57 take place winches 58 and the strands 57a and 57b of each of them extend on each side of the canvas.
Pour replier la toile, on agit sur les treuils 58 et 56 pour enrouler les brins 57b et pour rendre possible le déroulement des filins 52 pendant cette manoeuvre. La toile est ainsi rassemblée sur la plate-forme 59 et l'en- ceinte totalement découverte.To fold the fabric, it acts on the winches 58 and 56 to wind the strands 57b and to make possible the unwinding of the threads 52 during this maneuver. The canvas is thus gathered on the platform 59 and the enclosure totally uncovered.
Dans une variante de réalisation, la toile 54 peut être formée de plusieurs parties indépendantes manoeuvrables donc de manière séparée de la même manière que celle décrite ci-dessus, afin de découvrir ou couvrir toute ou partie de l'aire annulaire située sous elle. Dans ce cas, chaque partie de la toile 54 peut affecter la forme soit d'un rectangle soit d'un trapèze troussable et déployable de manière indépendante.In an alternative embodiment, the fabric 54 may be formed of several independent parts which can thus be operated in a separate manner in the same manner as that described above, in order to discover or cover all or part of the annular area situated beneath it. In this case, each part of the fabric 54 can affect the shape of either a rectangle or a trapezoidal troussable and deployable independently.
L'ossature représentée aux figures 6 à 8 comporte une pluralité de mâts verticaux 101 reliés entre eux par une ceinture 130 comportant des éléments articulés sur les mâts 101.The framework shown in FIGS. 6 to 8 comprises a plurality of vertical poles 101 interconnected by a belt 130 comprising articulated elements on the poles 101.
Chacun des mâts 101 comporte un montant vertical 120 ayant une extrémité inférieure qui peut être engagée dans un pied formant semelle et ayant une extrémité supé- rieure portant une poulie ou pourvue de tout système statique de renvoi pour une suspente.Each of the poles 101 has a vertical upright 120 having a lower end which can be engaged in a sole foot and having a top end. with a pulley or any static return system for a hanger.
Si besoin, les pieds peuvent comporter des oreilles latérales pour recevoir les extrémités de tangons d' entretoisement .If necessary, the feet may have side lugs to receive the ends of struts.
Un premier manchon 150 est enfilé sur le montant vertical 120 et arrêté sur ce dernier au moyen d'une goupille 151. Comme cela est plus particulièrement visible à la figure 7, le manchon 150 comporte une gorge 152. Ce manchon 150 délimite avec le montant 120 un espace annulaire 153 ouvert vers le haut capable d'accueillir deux pattes cylindriques 154a, 154b, chacune appartenant à une poutre 155a, 155b qui forme une entretoise entre deux poteaux consécutifs. La poutre est par exemple de section en I à âme pleine ou tubulaire, dont les ailes sont horizontales et dont les extrémités longitudinales sont équipées de gouttières ou berceaux verticaux 156a, 156b qui viennent reposer contre un montant 120 en épousant sa courbure. Les pattes susdites sont les prolongements, au- delà des ailes du I , de ces berceaux.A first sleeve 150 is threaded onto the vertical upright 120 and stopped on the latter by means of a pin 151. As is more particularly visible in Figure 7, the sleeve 150 has a groove 152. This sleeve 150 defines with the amount 120 an annular space 153 open upward able to accommodate two cylindrical legs 154a, 154b, each belonging to a beam 155a, 155b which forms a spacer between two consecutive posts. The beam is for example of I-section solid core or tubular, whose wings are horizontal and whose longitudinal ends are equipped with gutters or vertical cradles 156a, 156b which rest against a post 120 by matching its curvature. The aforesaid legs are the extensions, beyond the wings of I, these cradles.
Un second manchon 160 est ensuite enfilé sur le montant 120. Il est en tout point identique au manchon 150 ; il est simplement retourné par rapport à ce dernier. Il possède donc une gorge 162, définit un espace 163 qui accueille des pattes curvilignes 164a et 164b qui sont d'autres prolongations des berceaux 156a et 156b. Une goupille 161 assujettit le tout sur le montant 120.A second sleeve 160 is then threaded on the upright 120. It is in all respects identical to the sleeve 150; he simply returned from it. It thus has a groove 162, defines a space 163 which accommodates curvilinear tabs 164a and 164b which are further extensions of the cradles 156a and 156b. A pin 161 secures the whole on the amount 120.
Ce montage permet d'obtenir des angles A, entre deux poutres successives, variables si bien que la struc- ture élémentaire de l'ossature peut être standardisée en dimensions quelle que soit la dimension périphérique de 1 ' ossature .This arrangement makes it possible to obtain angles A, between two successive beams, so that the elementary structure of the framework can be standardized in size regardless of the peripheral dimension of the framework.
Chaque gorge 152, 162 reçoit l'œil de l'extrémité de deux élingues 164. Dans une variante non représentée adaptée aux abris de petites dimensions par exemple, un seul des manchons 150, 160 est équipé de ces élingues. Ces élingues relient deux mâts 101a séparés par un mât 101b. Au droit du mât 101b qu'elles évitent, elles en sont maintenues écartées par une fiche d'écartement 165. La figure 8 illustre une réalisation possible de cette fiche, solidaire de ou en une seule pièce avec le manchon 150, 160 correspondant, en forme de fourche ou chape, permettant de loger entre deux bras un treuil 166 ou une poulie de renvoi si nécessaire. Cette fiche d'écartement permet de supprimer les interférences entre les élingues et les mâts qu'elles évitent, qui peuvent se produire lorsque l'angle A est proche de 180°. Les élingues peuvent être de longueur ajustable de manière à pouvoir régler la géométrie de l'ossature. Elles jouent le rôle de tirants et dans une variante de réalisation qui le permet (angle A relativement fermé) , elles peuvent être remplacées par des barres à œil, également réglable en longueur par tout dispositif approprié. L'ensemble des poutres 156 et des élingues ou tirants constitue la ceinture de l'ossature indéformable qui peut encaisser les efforts centripètes engendrés par les tensions des suspentes et de la toile.Each groove 152, 162 receives the eye of the end of two slings 164. In a variant not shown adapted to small shelters for example, a only sleeves 150, 160 are equipped with these slings. These slings connect two masts 101a separated by a mast 101b. To the right of the mast 101b they avoid, they are kept apart by a spacer 165. Figure 8 illustrates a possible embodiment of this plug integral with or in one piece with the sleeve 150, 160 corresponding, in fork shape or clevis, for housing between a winch arm 166 or a return pulley if necessary. This spacer allows to eliminate interference between slings and masts they avoid, which can occur when the angle A is close to 180 °. The slings can be of adjustable length so as to adjust the geometry of the frame. They play the role of tie rods and in an alternative embodiment that allows it (angle A relatively closed), they can be replaced by eyebars, also adjustable in length by any suitable device. The set of beams 156 and slings or tie rods constitutes the belt of the indeformable frame which can absorb the centripetal forces generated by the tensions of the lines and the fabric.
Pour la stabilité de l'ossature périphérique, il importe qu'à la fois les poutres 155 et les tirants 164 convergent vers le centre des montants verticaux 120, comme illustré par la figure 8.For the stability of the peripheral framework, it is important that both the beams 155 and tie rods 164 converge towards the center of the uprights 120, as shown in FIG. 8.
On pourra en outre stabiliser les mâts 101 entre eux en prévoyant des contrefiches s ' étendant selon la diagonale du quadrilatère formé par deux mâts 101 adja- cents et la poutre 155 s ' étendant entre lesdits mâts (le dernier côté étant constitué par un tangon s 'étendant entre lesdits mâts, et, à défaut, par le sol lui-même) . The poles 101 can also be stabilized with each other by providing struts extending along the diagonal of the quadrilateral formed by two adjacent poles 101 and the beam 155 extending between said poles (the last side being constituted by a spinnaker pole). extending between these masts, and, failing that, by the ground itself).
