       BACKGROUND OF THE INVENTION 
       [0006]    1. Field of the Invention 
         [0007]    The present invention falls within the field of dismantlable and foldable shelters designed to be used outdoors, in particular of the folding tent type. 
         [0008]    The invention particularly relates to a device for setting up a shelter. 
         [0009]    Such a device will preferably, but not exclusively, be applicable in the arrangement of equipment offering space and a storage, stowage or product presentation surface. 
         [0010]    2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98. 
         [0011]    In a known manner, during demonstrations such as expositions, markets or similar occasions, each exhibitor and/or businessperson sets up a booth, or shelter, that comprises a framework made up of a dismantlable structure, and associated with a tarp or similar means. There are several types of dismantlable structures, and most often such structures are provided to be quickly and easily set up and dismantled. 
         [0012]    Dismantlable structures, which are primarily made from metal, include those made up of nesting elements, and those made up of deployable elements. 
         [0013]    Structures with deployable elements assume the form of a set of articulated profiles, of the pantograph type, to allow the transition from a deployed position suitable for supporting a tarp or similar member, to a folded position for transport. 
         [0014]    These structures with deployable elements comprise posts, generally four or six, designed to make up the legs of the structure, and profiles connecting two adjacent posts to form tie-beams, and optionally profiles connected to one another and each of the posts to form rafters. In the folded position, the posts are positioned parallel to one another, while the profiles are folded against one another between said posts. Furthermore, said posts can be provided to be telescoping. 
         [0015]    These deployable structures have many advantages relative to the other structure types, in particular regarding the ease and speed of installation. However, they are limited regarding the arrangement possibilities, in particular by adding a horizontal peripheral wall, for example to form a counter or bar, a tray, or an outward extension of the shelter, and/or a vertical wall to form a separation between the inside and the outside of said shelter, or to compartmentalize the inner space of said shelter. 
         [0016]    One solution is described in document FR 2,868,101, targeting a structure made up of a vertical upright along which two upper and lower arms are in particular articulated, at one end, the opposite end of which is able to cooperate by fastening with a post, through an assembly by pinching. To that end, each arm comprises a pair of profiles spaced apart and extending in parallel, said end of which grips said post on either side. Thus, the upper arm can serve as a support for a surface, in particular a plate, while the lower arm ensures the geometry of the structure thus formed. By fixing two identical structures on two adjacent beams, it is then possible to produce a counter or shelf, extending both toward the inside and outside relative to the structure of the shelter. 
         [0017]    More specifically, the ends of the profiles fastened with the posts each form part of the jaw of a clip. The inner surface of each part is configured to become complementary with respect to the outer section of the posts of the shelter. In particular, in the case of hexagonal posts, each part inwardly has two faces inclined relative to one another and ends with a lug at their free end. Thus, it is possible to orient the structure by allowing it to rotate around the post, according to angular portions corresponding to said section. In the case of a hexagonal section, it is then possible to orient the arms angularly every 60°. 
         [0018]    However, although such a solution forms bases each connected to a post of the shelter, it does not provide optimal stability of the surface that it receives, in particular lateral stability. Furthermore, the surface must necessarily bear on the horizontal arms, limiting the possible configurations. In short, set up is considerably limited in terms of possible arrangements. 
         [0019]    Other solutions, in particular using telescoping beams directly connected to the members of the structure of the shelter, are described in documents FR 2,753,220, U.S. Pat. No. 2,836,860 and DE 86 23 982 U1. These solutions once again do not make it possible to obtain a modular arrangement and stability of the elements thus attached on the structure of the shelter. 
       BRIEF SUMMARY OF THE INVENTION 
       [0020]    The present invention aims to offset the drawbacks of the state of the art, by proposing a device for setting up a shelter, made up of at least one beam connecting each of the aforementioned uprights using junction rings. The latter in particular ensure the vertical indexing of the height of said beam along each upright. Furthermore, such a beam is advantageously provided to be telescoping, so as to adapt lengthwise based on the angular orientation of the structure formed by the uprights and the arms. 
         [0021]    To that end, such a device for setting up a dismantlable and/or foldable shelter comprises at least two vertical uprights each equipped, at different levels, with at least two substantially horizontal arms, including a free end provided with fastening means in the form of a clip, characterized in that it also includes at least one telescoping beam provided at each of its ends with articulated connection means with a junction ring mounted in translation on each of the two uprights, this junction ring including means for preventing translational movement along said upright. 
         [0022]    Advantageously, several junction rings can be mounted along an upright for receiving more than one telescoping beam, at different levels. 
         [0023]    It is thus possible to position several beams quickly and easily above one another. Such beams may be called upon to extend horizontally, but also oriented in an inclined manner, owing to the articulated connection means. Furthermore, the telescoping nature of said beam makes it possible to adapt its length based on its position. 
         [0024]    The device according to the invention makes it possible to form at least one support bar for surface or support, said bar being able to be turned toward the inside or the outside of the shelter. In the case of a rigid surface, indexed at mid-height, the device can form a counter, offset inwardly or outwardly relative to its support structure. Several bars make it possible to form shelves or a wardrobe. 
         [0025]    Thus, the invention makes it possible to facilitate the addition of a horizontal wall on the periphery, for example, to form a counter or bar, shelves or a wardrobe.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    As shown in the attached figures, the present invention relates to a device  1  for setting up a shelter  2  of the dismantlable and/or foldable type, which, as shown in  FIGS. 1 and 2 , essentially includes at least four posts  3  on which a deployable and/or dismantlable structure  4  rests for receiving and stretching a tarp or canvas forming the roof (not shown). 
         [0033]    Thus, the set up device  1  according to the invention includes at least two vertical uprights  5 ,  6  each equipped, at different levels, with at least two arms, including a lower arm  7  and an upper arm  8 . These arms are able to extend substantially horizontally relative to these uprights  5 ,  6 , to which they are secured at one end  9 , preferably in an articulated manner. 
         [0034]    At their free end  10 , these arms  7 ,  8  are provided with clip-forming fastening means  11 . Through the latter, the arms  7 ,  8  and therefore the uprights  5 ,  6  can be attached, in different angular positions, around the posts  3  of the shelter  2 . 
         [0035]    According to the preferred embodiment, the arms  7 ,  8  extend horizontally or substantially horizontally, while the uprights  5 ,  6  extend vertically or substantially vertically. The plane formed by each pair of arms  7 ,  8  and its corresponding post  5  or  6  then extends vertically or substantially vertically, passing through the longitudinal median axis of each post  3  on which they are attached. 
         [0036]    Furthermore, according to the invention, the set up device  1  also includes a telescoping beam  12  provided, at each of its ends  13 ,  14 , with articulated connection means  15  cooperating with the junction ring  16  included by each of the uprights  5 ,  6 . 
         [0037]    More particularly, such a junction ring  16  is mounted in translation along an upright  5 ,  6 , in particular a ring on each upright  5 ,  6 . It includes immobilizing means  17  allowing it to be positioned at different levels along such an upright  5 ,  6 . 
         [0038]    Preferably, said immobilizing means  17  consists of indexing means for indexing the position of the junction ring  16  along such an upright  5 ,  6 . 
         [0039]    More particularly, such a junction ring  16  can be provided with an indexing elastic return finger  18  whereof one end can engage in one of the multiple holes  19  arranged along the upright  5 ,  6 . 
         [0040]    Of course, such immobilizing means  17  can assume other forms, for example fastening means by gripping. Furthermore, several junction rings  16  can be mounted on an upright  5 ,  6  to receive several telescoping beams  12 . 
         [0041]    According to the preferred embodiment, an upright  5 ,  6  has a polygonal outer section. Said ring  16  then consists of a sheath, with a globally cylindrical shape and provided to be hollow, designed to be crossed through from one end to the other by the upright  5 ,  6  on which it is translatably mounted. Furthermore, the inner section of the sheath has a shape complementary to, and larger dimensions of the outer section than, the shape and dimensions of said upright  5 ,  6 . According to the embodiments shown in the figures, the upright  5 ,  6  can have a polygonal section, in particular hexagonal. 
         [0042]    Furthermore, according to one advantageous embodiment, a junction ring  16  includes, on its periphery, arranged protruding, at least one lug  20  forming an eyelet and including a hole  22  for receiving a pin  23 , with which the articulated connecting means  15  is provided ending, each of the ends  13 ,  14 , a telescoping beam  12 . The cooperating assembly of the pin  23  within the hole  22  then forms a hinge pin. 
         [0043]    More particularly, such a pin  23  extends from a junction  24 , forming a base, mounted articulated, using the yoke  25 , on this end  13 ,  14  of the beam  12 . In particular, said junction  24  can assume the form of a tab whereof the lower end constitutes the pin  23 , while the opposite end, situated higher, cooperates with said yoke  25 . Furthermore, this cooperation can be done through a pivot link, in particular by means of fastening by screwing using a screw/nut pair, said screw crossing through said yoke  25  and said opposite end of said tab. 
         [0044]    According to one additional feature, said yoke  25  can be mounted articulated, pivoting relative to the end  13 ,  14  of the beam  12 . In particular, the rotation can be done around the longitudinal axis of said beam  12 . Such a pivot link is shown diagrammatically by arrows in  FIG. 4 . 
         [0045]    It should be noted that the rod forming the pin  23  can be kept in the hole  22  of a lug  20  of the junction ring  16  using a lever pin or similar member, just as it can assume the form of a threaded rod for receiving a tightening nut, as shown in the drawings. 
         [0046]    Owing to these articulated connection means  15 , a beam  12  can extend horizontally or inclined between two uprights  5 ,  6 . 
         [0047]    Furthermore, it greatly facilitates the assembly of this telescoping beam  12  on these uprights  5 ,  6 , the operator not being constrained in positioning them relative to one another. 
         [0048]    It should also be noted that the junction  24  from which the rod forming the pin  23  extends can be configured in the form of a cone trunk, like the mouth  26  of the hole  22  in the lugs  20 ,  21 , favoring self-centering of the parts relative to one another and their assembly without play. In particular, the frustoconical walls extend decreasing from the upper opening of said hole  22 , and in a complementary manner, at the rod forming the pin  23 . 
         [0049]    The telescoping beam  12  may be made up of two or more tubular profiles  27 ,  28  that can be nested in one another through complementary sections. In particular, a first profile, sliding inside the second profile, then has an outer section with a complementary shape and dimensions smaller than those of said second profile. 
         [0050]    It will be noted that the uprights  3 , as well as the beams  5 ,  6 , can also be provided to be telescoping, so that they can be folded and deployed. Furthermore, it is possible to adjust the height of the uprights  5 ,  6 , based on the level difference of the ground, but also to orient the beam  12  differently, in particular when the latter is positioned on a slant or diagonally between the junction rings  16 . 
         [0051]    Furthermore, the telescoping nature of the beam  12  makes it possible to adapt the length thereof, in particular during its positioning on a slant between the uprights  5 ,  6 , or based on the angular position of said arms  7 ,  8 . 
         [0052]    Furthermore, according to the invention, one or more fastening supports  29 ,  30  are mounted on this telescoping beam  12 , on which supports different accessories can be attached, for example a tray  31 , a wardrobe part  32 , etc. 
         [0053]    Such fastening supports  29 ,  30  can more particularly assume the form of a ring  33 , the inner section of which is adjusted to the outer section of one or the other of the profiles  27 ,  28  of the telescoping beam  12 . Preferably, in this respect, these profiles  27 ,  28  have a polygonal section facilitating the angular indexing of the fastening supports  29 ,  30  around the telescoping beam  12 . 
         [0054]    Said ring  33  can be secured to a fastening plate  34  on which, owing to appropriate fastening holes  35 , the aforementioned accessories can easily be attached. 
         [0055]    Essentially, it should be noted that the set up device  1  according to the invention advantageously contributes to ballasting the shelter  2  on the posts to which it is attached. This ballast becomes greater as accessories (trays, wardrobe, etc.) are added and loaded. This results in increased safety of such dismantlable and/or deployable shelters  2 . 
         [0056]    According to the preferred embodiment, the profiles making up the arms, uprights and beam can be made from a metal material, as can at least some of the articulations, while the other elements can be made from a plastic or composite material. Of course, the invention is in no way limited and various changes can be made thereto in terms of the shapes, materials and combinations of these various elements without going beyond the scope and spirit of the invention.
