Abstract

The cradle (1) has a blocking unit subjected to action of a helicoidal spring. The blocking unit is moved between a primary position in which a hinge allows relative movement of rods between them and a secondary position in which the rods are maintained in a state along predetermined relative orientation. The blocking unit cooperates, under action of the spring, with one of the rods on a part of their displacement between the positions for restoring the rods along the orientation. The hinge is provided with a deformable elastomeric element. An independent claim is also included for a framework for a shelter, including a wall that is made of cloth and provided with a basic frame.

Description

La présente invention concerne un arceau destiné à former une armature d'un abri comportant au moins une paroi de toile, ainsi qu'une armature et un abri comprenant un tel arceau.The present invention relates to a hoop for forming a frame of a shelter comprising at least one fabric wall, and a frame and a shelter comprising such a hoop.

Il est connu de l'état de la technique d'employer des arceaux composés de plusieurs tiges reliées entre elles par un moyen d'articulation élastique. Ce moyen d'articulation facilite le rangement des tiges qui peuvent ainsi être entreposées les unes contre les autres dans un sac afin de gagner de la place. Il prévient également la perte d'une tige, ce qui rendrait la tente inutilisable.It is known from the state of the art to use arches composed of several rods interconnected by means of elastic articulation. This means of articulation facilitates the storage of the rods which can thus be stored against each other in a bag to save space. It also prevents the loss of a rod, which would make the tent unusable.

D'une façon connue, le mode opératoire pour ériger une tente, consiste dans un premier temps à assembler manuellement plusieurs tiges les unes aux autres afin de former un arceau. Plusieurs ensembles de tiges sont ainsi assemblés afin de former un ensemble d'arceaux. Le nombre d'arceaux dépend essentiellement du gabarit de la tente ainsi que de la complexité de son architecture. Une tente de grande dimension peut par exemple être subdivisée en plusieurs parties formant chacune une pièce à l'intérieur de la tente. L'assemblage des tiges se fait généralement par emboitement d'une tige dans une autre. Une fois les arceaux assemblés, ceux ci sont dans un deuxième temps enfilés à travers des passants se trouvant sur la toile de tente. La disposition des passants sur la toile va induire une courbure générale des différents arceaux afin de conférer à la tente une forme stable, définitive et prédéterminée.In a known manner, the procedure for erecting a tent, consists in a first step to manually assemble several rods to each other to form a hoop. Several sets of rods are thus assembled to form a set of arches. The number of arches depends mainly on the size of the tent as well as the complexity of its architecture. For example, a large tent can be subdivided into several parts, each forming a room inside the tent. The assembly of the rods is generally by interlocking one rod in another. Once the arches assembled, these are in a second time threaded through passers-by lying on the tent. The arrangement of passers-by on the fabric will induce a general curvature of the different arches to give the tent a stable, definitive and predetermined shape.

Le montage d'une tente selon ce mode opératoire peut s'avérer long et fastidieux surtout dans le cas d'une tente de grande taille possédant plusieurs compartiments.The mounting of a tent according to this procedure can be long and tedious especially in the case of a large tent with several compartments.

Il est également connu de l'état de la technique d'employer des tentes à montage rapide qui ne nécessitent ni l'assemblage des tiges entres elles ni le passage des arceaux dans les passants, utilisant des armatures flexibles.It is also known from the state of the art to use quick-erect tents that do not require either the assembly of the rods between them or the passage of the poles in the loops, using flexible armatures.

Cependant de telles tentes sont restreintes au niveau de leur taille et de leur modularité. Elles ont une architecture très figées et sont de plus très encombrantes au transport car les arceaux ne sont pas composés d'une multitude de tiges. Une telle tente se plie généralement sur elle-même en une multitude de cercles avec un rayon de courbure plus ou moins importante afin de pouvoir ranger la tente à l'intérieur d'un sac. Les dimensions de la tente sont donc dépendantes du rayon de courbure des arceaux. Un rayon de courbure trop grand permet la réalisation d'une tente de grande dimension mais induira un encombrement conséquent au transport. De la même manière un rayon de courbure trop petit permet un encombrement réduit au transport mais induira une faible dimension de tente.However, such tents are restricted in size and modularity. They have a very fixed architecture and are also very cumbersome to transport because the arches are not composed of a multitude of rods. Such a tent usually folds on itself in a multitude of circles with a radius of curvature more or less important to store the tent inside a bag. The dimensions of the tent are therefore dependent on the radius of curvature of the hoops. A radius of curvature Too big allows the realization of a large tent but will induce a significant congestion to transport. In the same way a radius of curvature too small allows a small space to transport but will induce a small dimension of tent.

Il est également connu notamment du document EP0507012 d'utiliser des tentes présentant une armature de type parapluie restant à demeure dans la toile de tente, et pouvant être repliée avec un système de bielles. Un tel système contraint la forme de la tente et sa structure complexe diminue sa fiabilité.It is also known from the document EP0507012 to use tents having an umbrella type frame remaining permanently in the tent fabric, and can be folded with a system of connecting rods. Such a system constrains the shape of the tent and its complex structure decreases its reliability.

La présente invention a pour objectif de proposer une solution à ces inconvénients.The present invention aims to propose a solution to these disadvantages.

A cet effet, la présente invention a pour objet un arceau destiné à former une armature d'un abri comportant au moins une paroi de toile comprenant au moins deux tiges reliées l'une à l'autre sur l'une de leur extrémité par des moyens d'articulation caractérisé en ce qu'il comprend des moyens de blocage soumis à l'action de moyens élastiques, les moyens de blocage étant mobile entre une première position dans laquelle les moyens d'articulation autorisent un mouvement relatif des tiges entre elles selon au moins un degré de liberté de rotation, et une seconde position dans laquelle les deux tiges sont maintenues en position selon une orientation relative prédéterminée, les moyens de blocage coopérant sous l'action des moyens élastiques avec au moins l'une des tiges sur une partie de leur déplacement entre la première et la seconde position pour ramener les tiges selon l'orientation relative prédéterminée, et les moyens d'articulation comprenant un organe en matériau déformable.For this purpose, the subject of the present invention is a hoop intended to form a reinforcement of a shelter comprising at least one fabric wall comprising at least two rods connected to one another on one of their ends by means of hinge means characterized in that it comprises locking means subjected to the action of resilient means, the locking means being movable between a first position in which the hinge means allow relative movement of the rods between them according to at least one degree of freedom of rotation, and a second position in which the two rods are held in position in a predetermined relative orientation, the locking means cooperating under the action of the elastic means with at least one of the rods on a part of their movement between the first and the second position to return the rods in the predetermined relative orientation, and the hinge means comprising a matte member riau deformable.

Cette disposition permet de plier l'arceau selon les moyens d'articulation se trouvant entre les différentes tiges afin d'obtenir un minimum d'encombrement de l'arceau et ainsi de faciliter son rangement à l'intérieur d'un sac par exemple. Mais surtout cette disposition permet l'érection facilitée de l'arceau grâce à l'alignement de toutes les tiges adjacentes selon une orientation relative prédéterminée. Cette orientation est tout d'abord rendue possible par l'action des moyens d'articulation qui tendent à rapprocher les orientations des extrémités de deux tiges reliées, puis par l'action des moyens élastique sur les moyens de blocage qui vont pousser sur la paroi latérale extérieure de la tige afin de la redresser puis de la bloquer dans les moyens de blocage lorsque celle-ci sera suffisamment redressée. L'emploi d'un matériau déformable permet aux tiges de se mouvoir facilement l'une par rapport à l'autre conférant ainsi le degré de liberté en rotation.This arrangement makes it possible to fold the hoop according to the hinge means located between the different rods in order to obtain a minimum of space in the hoop and thus to facilitate its storage inside a bag for example. But especially this arrangement allows the easy erection of the arch by aligning all adjacent rods in a predetermined relative orientation. This orientation is first made possible by the action of the hinge means which tend to bring the orientations of the ends of two connected rods, then by the action of the elastic means on the locking means which will push on the wall external side of the rod to straighten it and then block it in the locking means when it is sufficiently rectified. The use of a material deformable allows the rods to move easily relative to each other thus conferring the degree of freedom in rotation.

Selon un mode de réalisation, les moyens de blocage possèdent une extrémité formant un fourreau de guidage de la tige afin de la ramener selon son orientation relative prédéterminée.According to one embodiment, the locking means have an end forming a guiding sheath of the rod in order to bring it back to its predetermined relative orientation.

Cette disposition permet aux moyens de blocage de prendre appui sur la surface latérale extérieure de la tige à redresser et de la guider vers l'intérieur du fourreau. Une fois à l'intérieur du fourreau, la tige est maintenue fixe dans les moyens de blocage sous l'action des moyens élastiques.This arrangement allows the locking means to bear on the outer lateral surface of the rod to be straightened and guide it towards the inside of the sheath. Once inside the sheath, the rod is held fixed in the locking means under the action of the elastic means.

Avantageusement, le matériau déformable est un matériau élastique, notamment un élastomère.Advantageously, the deformable material is an elastic material, in particular an elastomer.

Cette disposition permet d'obtenir une première force de rappel dirigée à l'encontre des moyens de blocage.This arrangement makes it possible to obtain a first return force directed against the locking means.

Dans un mode de réalisation, les moyens de blocage comprennent des moyens favorisant sa préhension.In one embodiment, the locking means comprise means for promoting its gripping.

Ces moyens sont utiles au moment du pliage de l'arceau. En effet, lors du pliage il faut ramener les organes de blocage suivant leur première position ce qui va à l'encontre de la position d'équilibre des moyens élastiques, notamment du ressort. Un opérateur doit pouvoir se saisir facilement des moyens de blocage afin d'exercer une force sur les moyens élastiques, ce qui permettra le dégagement de la tige de l'intérieur du fourreau et donc le pliage de l'arceau en effectuant successivement la même opération à l'ensemble des moyens d'articulations.These means are useful at the time of folding the hoop. Indeed, during folding must bring the locking members in their first position which goes against the equilibrium position of the elastic means, including the spring. An operator must be able to easily grasp the locking means in order to exert a force on the elastic means, which will allow the release of the rod from the inside of the sheath and thus the folding of the hoop by successively performing the same operation to all the means of articulation.

Avantageusement, l'élément élastique est entièrement caché par les moyens de blocage.Advantageously, the elastic element is completely hidden by the locking means.

Cette disposition rend l'arceau plus esthétique mais permet surtout d'éviter que les doigts ou la main de l'opérateur ne soient pris par les moyens élastiques lors de leur passage de la deuxième à la première position.This arrangement makes the arch more aesthetic but above all it makes it possible to prevent the fingers or the hand of the operator from being caught by the elastic means during their passage from the second to the first position.

Selon un mode de réalisation, au moins une portion des tiges est tubulaire.According to one embodiment, at least a portion of the rods is tubular.

Cette disposition facilite la solidarisation des tiges avec les moyens d'articulation, notamment dans le cas de l'utilisation d'un élastomère pouvant être serti ou collé à l'intérieur de cette portion.This arrangement facilitates the securing of the rods with the hinge means, especially in the case of the use of an elastomer that can be crimped or glued within this portion.

Selon le même mode de réalisation, les moyens d'articulation sont fixés dans les portions tubulaires des tiges.According to the same embodiment, the hinge means are fixed in the tubular portions of the rods.

Cette fixation dans les portions tubulaires des tiges permet d'exercer la force de rappel des moyens d'articulation vers l'intérieur de la tige et d'orienter les tiges suivant leur axe de symétrie, ce qui aide à l'orientation de la tige à l'intérieur du fourreau.This fixing in the tubular portions of the rods makes it possible to exert the restoring force of the articulation means towards the inside of the rod and to orient the rods along their axis of symmetry, which aids in the orientation of the rod. inside the sheath.

Avantageusement, les moyens de blocage comprennent des moyens de coopération avec des moyens de blocages d'une articulation appartenant à un arceau distinct du même type. L'invention porte également sur une armature pour un abri comportant au moins une paroi de toile comprenant au moins un arceau. Enfin, l'invention porte également sur un abri comportant au moins une paroi de toile présentant des passants dans lesquels passe un arceau.Advantageously, the locking means comprise means for cooperation with locking means of a joint belonging to a separate arch of the same type. The invention also relates to a frame for a shelter comprising at least one fabric wall comprising at least one hoop. Finally, the invention also relates to a shelter comprising at least one fabric wall having loops in which passes a hoop.

L'application de ce type d'arceau à l'armature d'un abri comportant au moins une paroi de toile, par exemple une tente de camping, permet le repli d'une tente sans avoir à retirer les arceaux des passants de la toile de tente et permet l'érection de celle-ci par le simple fait de relâcher librement les arceaux de toute contrainte extérieure forçant les moyens de blocage de ses articulations à se maintenir dans leur deuxième position.The application of this type of arch to the frame of a shelter with at least one canvas wall, for example a camping tent, allows the folding of a tent without having to remove the arches passers of the canvas tent and allows the erection thereof simply by releasing freely the arches of any external constraint forcing the locking means of his joints to maintain their second position.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution d'un arceau pour tente selon l'invention.In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of non-limiting examples, several embodiments of a tent arch according to FIG. invention.

Les figures 1a et 1b présentent respectivement une vue en coupe de l'articulation d'un arceau suivant un premier mode de réalisation de l'invention dans sa première position dite ouverte et dans sa seconde position dite fermée.The Figures 1a and 1b respectively show a sectional view of the articulation of a hoop according to a first embodiment of the invention in its first so-called open position and in its second so-called closed position.

Les figures 2a et 2b présentent respectivement l'articulation d'un arceau suivant un deuxième mode de réalisation de l'invention dans sa première position dite ouverte et dans sa seconde position dite fermée.The Figures 2a and 2b respectively present the articulation of a hoop according to a second embodiment of the invention in its first so-called open position and in its second so-called closed position.

Les figures 3a à 3d présentent l'articulation d'un arceau suivant un troisième mode de réalisation.The Figures 3a to 3d present the articulation of a hoop according to a third embodiment.

La figure 4 montre la vue partiel d'une tente de camping équipé d'arceaux selon l'invention.The figure 4 shows the partial view of a camping tent equipped with hoops according to the invention.

Selon un premier mode de réalisation, l'arceau présenté sur les figures 1a et 1b comprend un semble de tiges 2a, 2b. Au niveau d'une articulation entre deux tiges adjacentes, ces deux tiges 2a, 2b comportent chacune sur leur extrémité un tube 16a, 16b emmanché jusqu'à une butée 17 disposée transversalement sur une portion des tubes 16a, 16b. Pour une meilleure stabilité, ces tubes 16a, 16b sont collés aux tiges 2a, 2b sur toute leur surface intérieure en contact avec les tiges 2a, 2b. La butée 17 permet de faire ressortir une portion tubulaire 11 de ces deux tubes 16a, 16b de l'extrémité de chacune des tiges 2a, 2b. Ces deux portions tubulaires 11 sont utilisées pour sertir un élastomère 8 servant à relier élastiquement les deux tiges 2a, 2b entres elles.According to a first embodiment, the hoop presented on the Figures 1a and 1b comprises an appearance of stems 2a, 2b. At a joint between two adjacent rods, these two rods 2a, 2b each have on their end a tube 16a, 16b fitted to a stop 17 disposed transversely on a portion of the tubes 16a, 16b. For better stability, these tubes 16a, 16b are glued to the rods 2a, 2b over their entire inner surface in contact with the rods 2a, 2b. The stop 17 makes it possible to bring out a tubular portion 11 of these two tubes 16a, 16b of the end of each of the rods 2a, 2b. These two tubular portions 11 are used to crimp an elastomer 8 serving to elastically connect the two rods 2a, 2b between them.

Le tube 16a présente de plus un épaulement 18 sur son extrémité ayant été inséré dans la tige 2a. Cet épaulement 18 sert d'appui à un ressort 5 hélicoïdal disposé autour du tube 16a. Le ressort 5 possède un diamètre intérieur sensiblement égal au diamètre extérieur du tube 16a, le tube 16a sert ainsi de guide au ressort 5 qui ne peut ainsi exercer qu'une force dirigée selon l'axe 19 de la tige 2a.The tube 16a further has a shoulder 18 on its end having been inserted into the rod 2a. This shoulder 18 serves to support a helical spring 5 disposed around the tube 16a. The spring 5 has an inside diameter substantially equal to the outside diameter of the tube 16a, the tube 16a thus serves as a guide spring 5 which can thus exert a force directed along the axis 19 of the rod 2a.

Un moyen de blocage 4 est disposé coaxialement à la tige 2a. Ce moyen de blocage 4 est dans ce mode de réalisation composé de deux pièces distinctes : une première pièce constituant le corps 20 du moyen de blocage 4 et une deuxième pièce constituant une butée 21 du moyen de blocage 4 sur sa partie inférieure 6b. Le corps 20 du moyen de blocage recouvre entièrement le tube 16a ainsi que le ressort 5 s'y rapportant. Ce corps présente un épaulement 22 sur sa surface intérieure servant d'appui à la deuxième extrémité du ressort hélicoïdal. Cet épaulement 22 est sensiblement d'un diamètre égal au diamètre extérieur du ressort 5 hélicoïdal et de l'épaulement 18 servant de premier appui à ce même ressort 5. Le ressort 5 se retrouve ainsi emprisonné à l'intérieur d'un logement délimité par le tube 16a, le corps 20 ainsi que leur épaulement respectif 18, 22.A locking means 4 is disposed coaxially with the rod 2a. This locking means 4 is in this embodiment composed of two separate parts: a first part constituting the body 20 of the locking means 4 and a second part forming a stop 21 of the locking means 4 on its lower part 6b. The body 20 of the locking means completely covers the tube 16a and the spring 5 thereto. This body has a shoulder 22 on its inner surface serving as a support for the second end of the coil spring. This shoulder 22 is substantially of a diameter equal to the outside diameter of the helical spring 5 and the shoulder 18 serving as a first support for the same spring 5. The spring 5 is thus trapped inside a housing delimited by the tube 16a, the body 20 and their respective shoulder 18, 22.

La butée 21 est quant à elle montée coulissante dans la tige 2a avant l'insertion du tube 16a. Cette butée 21 présente sur sa surface intérieure un épaulement 23 dont le diamètre correspond sensiblement au diamètre extérieur du corps 20 pris dans cette zone. La butée 21 est rendue solidaire du corps 20 par vissage ou par tout autre moyen équivalent.The stop 21 is slidably mounted in the rod 2a before the insertion of the tube 16a. This stop 21 has on its inner surface a shoulder 23 whose diameter substantially corresponds to the outer diameter of the body 20 taken in this area. The stop 21 is made integral with the body 20 by screwing or by any other equivalent means.

Le corps 20 présente sur sa partie supérieure une ouverture constituant un fourreau 7 pour l'autre tige 2b. Les bords de cette ouverture sont fraisés afin de faciliter l'entrée de l'extrémité de la tige 2b ou plus précisément dans ce mode de réalisation de l'extrémité du tube 16b emmanché dans la tige 2b. La surface extérieure du corps présente également plusieurs gorges sensiblement annulaires destinées à accueillir des doigts de la main. Une position d'équilibre d'une articulation 3 peut être définie comme étant la position dans laquelle le ressort 5 est détendu à son maximum dans son logement et l'extrémité du tube 16b se trouve insérée dans le fourreau 7.The body 20 has on its upper part an opening constituting a sheath 7 for the other rod 2b. The edges of this opening are milled to facilitate entry of the end of the rod 2b or more precisely in this embodiment of the end of the tube 16b fitted into the rod 2b. The outer surface of the body also has a plurality of substantially annular grooves for receiving fingers of the hand. A equilibrium position of a joint 3 can be defined as the position in which the spring 5 is expanded to its maximum in its housing and the end of the tube 16b is inserted into the sheath 7.

Comme il est possible de le voir sur la figure 4, les arceaux sont reçus dans les passants 15 d'une toile 14 de tente 13, un ensemble d'arceau constituant une armature 12 pour cette tente.As it is possible to see on the figure 4 the hoops are received in the loops 15 of a canvas 14 tent 13, a set of hoop constituting a frame 12 for this tent.

Selon un second mode de réalisation présenté aux figures 2a et 2b, l'articulation 3 d'un arceau 1 comprend deux tiges 2a et 2b. Ces deux tiges 2a, 2b comportent une portion tubulaire 11 sur leur extrémité concordante. Un élastomère 8 est directement serti dans les portions tubulaires 11 de ces tiges 2a, 2b afin de les relier entre elles.According to a second embodiment presented to Figures 2a and 2b the hinge 3 of a hoop 1 comprises two rods 2a and 2b. These two rods 2a, 2b have a tubular portion 11 on their concordant end. An elastomer 8 is directly crimped into the tubular portions 11 of these rods 2a, 2b in order to connect them together.

Une pièce 10 servant d'appui au ressort 5 est disposée sur la tige 2a. Cette pièce est de forme sensiblement annulaire et est maintenue fixe sur la tige 2a par l'intermédiaire d'une vis 24 appuyant directement sur la tige 2a et se vissant dans un filetage transversal à la tige 2a taraudé directement dans cette même pièce 10.A piece 10 for supporting the spring 5 is disposed on the rod 2a. This piece is of substantially annular shape and is held fixed on the rod 2a by means of a screw 24 pressing directly on the rod 2a and screwing in a transverse thread to the rod 2a threaded directly into the same piece 10.

Le ressort 5 a une géométrie hélicoïdale et est emmanché directement sur la tige 2a à l'encontre de la pièce 10, le diamètre intérieur du ressort 5 et le diamètre extérieur de la tige 2a étant sensiblement égaux afin de permettre une poussée uniforme du ressort 5 le long de la tige 2a.The spring 5 has a helical geometry and is fitted directly on the rod 2a against the part 10, the inner diameter of the spring 5 and the outer diameter of the rod 2a being substantially equal in order to allow a uniform thrust of the spring 5 along the rod 2a.

Un moyen de blocage 4 est ensuite monté coulissant sur la tige 2a. Ce moyen de blocage 4 est dans ce mode de réalisation constitué d'une seule pièce de forme générale cylindrique assimilable au corps 20 du moyen de blocage selon le précédent mode de réalisation. Ce corps comporte une extrémité inférieure 6b tournée vers le ressort et une extrémité supérieure 6a tournée vers l'autre tige 2b.A locking means 4 is then slidably mounted on the rod 2a. This locking means 4 is in this embodiment consisting of a single piece of generally cylindrical shape comparable to the body 20 of the locking means according to the previous embodiment. This body has a lower end 6b facing the spring and an upper end 6a facing the other rod 2b.

L'extrémité inférieure 6b comporte un épaulement 22 servant d'appui à la seconde extrémité du ressort 5 et une partie cylindrique de diamètre légèrement supérieur au diamètre extérieur du ressort 5 s'étendant à partir de cet épaulement 22 en direction du ressort 5.The lower end 6b has a shoulder 22 serving to support the second end of the spring 5 and a cylindrical portion of diameter slightly greater than the outside diameter of the spring 5 extending from this shoulder 22 towards the spring 5.

L'extrémité supérieure 6a comporte elle aussi un épaulement 25 avec une partie conique puis cylindrique s'étendant en direction de la tige 2b à partir de cet épaulement 25. Cette extrémité supérieure 6a ainsi qu'une portion du corps 20 cylindrique disposé tout de suite en aval de l'épaulement 25 servent de fourreau 7 à la tige 2b. Le diamètre intérieur du corps 20 du moyen de blocage 4 est sensiblement inférieur au diamètre extérieur de la tige 2b afin de permettre à l'arceau 1 de s'arquer selon une courbure générale et de permettre son utilisation comme armature 12 pour une toile 14 de tente 13.The upper end 6a also has a shoulder 25 with a conical then cylindrical portion extending towards the rod 2b from this shoulder 25. This upper end 6a and a portion of the cylindrical body disposed immediately. downstream of the shoulder 25 serve as sheath 7 to the rod 2b. The inside diameter of the body 20 of the locking means 4 is substantially less than the outside diameter of the rod 2b in order to to allow the hoop 1 to be arched according to a general curvature and to allow its use as a frame 12 for a canvas 14 tent 13.

Dans ce second mode de réalisation, la surface extérieure de la partie du corps 20 se trouvant entre les deux épaulements 22 et 25 sert de moyen de préhension 9 du moyen de blocage 4.In this second embodiment, the outer surface of the portion of the body 20 located between the two shoulders 22 and 25 serves as gripping means 9 of the locking means 4.

La position d'équilibre de l'articulation dans ce second mode de réalisation est ici définie de la même manière que pour le premier mode de réalisation mise à part que dans ce mode de réalisation le ressort ne se trouve pas emprisonné à l'intérieur d'un logement.The equilibrium position of the joint in this second embodiment is here defined in the same manner as for the first embodiment except that in this embodiment the spring is not trapped inside the 'housing.

Selon un troisième mode de réalisation, les extrémités des tubes 16a, 16b sont surmoulés par l'élastomère 8. Ce surmoulage cache les extrémités des tubes 16a, 16b ce qui les rend moins vulnérables surtout lors du repli des arceaux 1 de la tente 13. Dans ce troisième mode de réalisation, les moyens favorisant la préhension de la poignée sont constitués par un revêtement agrippant. Pour le reste, ce troisième mode de réalisation reprend les caractéristiques structurelles du premier mode de réalisation susmentionné. Pour ériger une tente 13 de camping équipée d'une armature 12 constituée d'arceaux 1 selon l'invention, le campeur retire dans un premier temps la tente de son conditionnement en maintenant la tente 13 à l'état plié. Dans cet état les tiges adjacentes de chaque arceau sont maintenues dans la position telle que représentée à la figure 3d. Ce conditionnement (non représenté) sert à protéger et à maintenir la tente pliée afin de minimiser son encombrement. Il peut être directement constitué par la toile 14 de tente 13 mais est typiquement constitué d'un sac afin de protéger également la toile 14 de tente 13. A l'état plié, les articulations 3 des arceaux 1 de la tente 13 ne se trouvent pas à l'état d'équilibre défini précédemment et ont tendance à exercer une force afin de rejoindre cet état. Les moyens de blocages 4 se trouvent alors dans une position P1 autorisant un mouvement relatif des tiges 2a, 2b entre elles selon au moins un degré de liberté de rotation. Le campeur dispose alors la tente 13 au sol.According to a third embodiment, the ends of the tubes 16a, 16b are overmoulded by the elastomer 8. This overmoulding conceals the ends of the tubes 16a, 16b which makes them less vulnerable especially during the folding of the arches 1 of the tent 13. In this third embodiment, the means for gripping the handle are constituted by a gripping coating. For the rest, this third embodiment incorporates the structural features of the first embodiment mentioned above. To erect a camping tent 13 equipped with a frame 12 consisting of arches 1 according to the invention, the camper initially removes the tent from its conditioning by maintaining the tent 13 in the folded state. In this state the adjacent rods of each arch are held in the position as shown in FIG. figure 3d . This packaging (not shown) serves to protect and maintain the folded tent to minimize its bulk. It can be directly constituted by the tent fabric 13 but is typically constituted by a bag so as to also protect the canvas 14 of the tent 13. In the folded state, the joints 3 of the arches 1 of the tent 13 can be found not at the equilibrium state defined above and tend to exert a force to join this state. The locking means 4 are then in a position P1 allowing a relative movement of the rods 2a, 2b therebetween in at least one degree of freedom of rotation. The camper then has tent 13 on the ground.

Chaque articulation se retrouve sous la contrainte du ressort 5 et de la pièce en élastomère 8. La pièce élastomère n'étant pas dans son état de repos ; l'articulation va s'ouvrir dans un premier temps grâce à la force de rappel de la pièce élastomère qui est loin de sa position de repos. L'articulation sera ensuite verrouillée grâce au déplacement du coulisseau, actionné alors par le ressort dont l'efficacité augmente lorsque les tiges deviennent co-axiales grâce à la poussée de l'élastomère. Cet état de verrouillage est représenté par les figures 1b, 3a et 3b. Proche de la co-axialité, la force de l'élastomère est faible car proche de sa position repos, par contre la force du ressort est grande car il est dans sa zone de fonctionnement optimale. Il est à noter que les contributions de l'élastomère et du ressort dans le mouvement dépendent du choix de la raideur réciproque de ceux-ci.:Each joint is found under the stress of the spring 5 and the elastomer part 8. The elastomeric piece is not in its rest state; the joint will open in a first time thanks to the restoring force of the elastomeric piece which is far from its rest position. The articulation will then be locked thanks to the displacement of the slider, then actuated by the spring whose efficiency increases when the stems become co-axial thanks to the thrust of the elastomer. This lock state is represented by the figures 1b , 3a and 3b . Close to coaxiality, the strength of the elastomer is low because close to its rest position, against the spring force is great because it is in its optimal operating area. It should be noted that the contributions of the elastomer and the spring in the movement depend on the choice of the reciprocal stiffness of these:

Le moyen de blocage se retrouve alors dans une position P2 illustrée par les figures 1b, 2b, 3a et 3b dans laquelle les deux tiges 2a, 2b sont maintenues en position selon une orientation relative déterminée et conditionnée par les passants 15 de la toile 14 de tente 13. Par le biais d'une armature 12 de tente 13 constituée d'arceaux 1 selon l'invention, on obtient donc une tente 13 sans contraintes de dimensionnement et dont l'érection est facilitée.The blocking means is then found in a position P2 illustrated by the Figures 1b, 2b , 3a and 3b in which the two rods 2a, 2b are held in position in a determined relative orientation and conditioned by the loops 15 of the canvas 14 tent 13. Through a reinforcement 12 tent 13 consisting of arches 1 according to the invention, we thus obtain a tent 13 without sizing constraints and whose erection is facilitated.

Pour replier la tente 13, le campeur saisi un par un les moyens de blocage 4 de chaque articulation 3 par son moyen de préhension 9 et exerce une force à l'encontre du ressort 5 permettant de ramener le moyen de blocage 4 en position P1 et ainsi de libérer la tige 2b de ce moyen de blocage 4, comme montré sur les figures 1a et 3c. L'élastomère 8 permet de plier l'articulation 3 afin de ramener l'ensemble des tiges selon une position permettant de les maintenir avec les deux mains comme illustré sur les figures 2a et 3d. Le campeur roule ensuite l'ensemble des tiges ainsi pliées dans la toile 14 de la tente 13 pouvant servir au maintient de cette position de repli. Le campeur range ensuite le tout dans le conditionnement de la tente 13, typiquement un sac.To fold the tent 13, the camper seized one by one the locking means 4 of each hinge 3 by its gripping means 9 and exerts a force against the spring 5 to bring the locking means 4 to position P1 and thus to release the rod 2b of this locking means 4, as shown in the figures 1a and 3c . The elastomer 8 makes it possible to fold the articulation 3 in order to bring the set of stems back to a position that allows them to be held with both hands as shown on the drawings. Figures 2a and 3d . The camper then rolls all the rods thus folded in the canvas 14 of the tent 13 can be used to maintain this folded position. The camper then arranges everything in the packaging of the tent 13, typically a bag.

Selon une variante, il serait également possible de faciliter la préhension par la présence d'un revêtement de surface évitant le glissement.According to a variant, it would also be possible to facilitate gripping by the presence of a surface coating that prevents slippage.

Selon une variante, il est possible de prévoir des moyens de coopération entre les moyens de blocages de différentes articulations appartenant à des arceaux différents permettant de les entraîner ensemble pour débloquer les articulations correspondantes. Ces moyens de mise de coopération peuvent comporter notamment : un revêtement agrippant, ou un système mécanique d'emboîtement entre les moyens de blocages, ou encore des passants pouvant être réunis par un élément de liaison comme une sangle.According to a variant, it is possible to provide means for cooperation between the locking means of different joints belonging to different hoops for driving together to unlock the corresponding joints. These engagement means may comprise in particular: a gripping coating, or a mechanical interlocking system between the blocking means, or loops that can be joined by a connecting element such as a strap.

Comme il va de soi, l'invention ne se limite pas aux deux modes de réalisation préférentiels décrits ci-dessus, à titre d'exemple non limitatif ; elle en embrasse au contraire toutes les variantes, en particulier la combinaison de deux modes de réalisation où une seule des tiges 2a, 2b peut comporter un tube 16a emmanché sur son extrémité tandis que l'extrémité de l'autre tige 2b comporte directement une portion tubulaire 11 servant à sertir l'élastomère 8. Il est à noter également qu'il existe de nombreuses possibilités de réalisations de l'emmanchement de l'élastomère, notamment par ajustement serré, réalisé par différence de température par exemple, par usinage, rivetage ou goupilles, par sertissage de l'extrémité du tube ou d'une section, par collage, par moulage (injection plastique) ou surmoulage ou encore par l'intermédiaire d'une pièce de liaison. Les arceaux peuvent comporter un nombre variable de tiges et d'articulation selon la taille et la forme de l'armature recherchée.It goes without saying that the invention is not limited to the two preferred embodiments described above, by way of non-limiting example; on the contrary, it encompasses all variants, in particular the combination of two embodiments where only one of the rods 2a, 2b may comprise a tube 16a fitted on its end while the end of the other rod 2b directly comprises a tubular portion 11 serving to crimp the elastomer 8. It should be noted also that there are many possibilities of embodiments of the fitting of the elastomer, in particular by tight adjustment, made by temperature difference for example, by machining, riveting or pins, by crimping the end of the tube or a section, by gluing, by molding (plastic injection) or overmolding or by means of a connecting piece. The arches may include a variable number of rods and articulation depending on the size and shape of the desired frame.
