Folding structure that can be unfolded and refolded quickly

Abstract

The invention relates to a folding shelter structure capable of being reconfigured from an unfolded position to a folded position, and vice versa. The structure includes telescopic uprights, each upright having at least one lower element sliding inside an upper element secured to the structure and which support a collection of mutually-adjacent prismatic box structures, and walls being formed by crisscross longitudinal members articulated in the manner of scissors. The structure includes unfolding or re-folding devices that are built into the telescopic uprights.

1 . Folding shelter structure passing from an unfolded position to a folded position, and vice versa, comprising:
 a plurality of telescopic uprights, each upright being comprised of an upper element, a lower element sliding with respect to said upper element and being integral therewith; and   a collection of mutually-adjacent prismatic box structures being supported by the uprights and being further comprised of walls formed of crisscrosses of longitudinal members articulated in a scissors-type manner, each upright being still further comprised of means for unfolding or re-folding, incorporated into the telescopic uprights, said upper element comprising a guiding means formed of a slide, extending over at least part of a length of said upper element, said guiding means cooperating with rolling means formed of a carriage and sliding inside the the carriage, said rolling means having ends of longitudinal members mounted thereon in an articulated manner.   
   
   
       2 . Folding structure according to  claim 1 , wherein said lower element slides inside said upper element. 
   
   
       3 . Folding structure according to  claim 1 , wherein said means for unfolding or re-folding are formed of pneumatic jacks. 
   
   
       4 . Folding structure according to  claim 1 , having a polygonal plane, each side of said polygonal plane supporting a different odd number of boxes. 
   
   
       5 . Folding structure according to  claim 1 , further comprising:
 a secondary unfolding means or at least one jack positioned diagonally with respect to at least one lozenge constituted at a level of an articulated crisscross formed by longitudinal members, on a side of at least one of a box structure.   
   
   
       6 . Folding structure according to  claim 1 , further comprising:
 a cross-piece being fixed at a periphery thereof and on an end of longitudinal members bearing a covering means, having a lower portion coupling at least one horizontal traverse.   
   
   
       7 . Folding structure according to  claim 6 , wherein the horizontal traverse is comprised of at least two segments mounted and articulated by a hinge. 
   
   
       8 . Folding structure according to  claim 6 , wherein the horizontal traverse is cooperative with a recess formed by the upper portion of an upright. 
   
   
       9 . Folding structure according to  claim 1 , further comprising:
 a reinforcement cooperating with a recess of the upper portion of an upright and with a recess of a horizontal traverse adjacent to said upper portion, a connection solidifying in an unfolded position, after immobilization of said reinforcement by a locking means.   
   
   
       10 . Folding structure according to  claim 7 , further comprising:
 a reinforcement cooperating with recesses of two segments of a horizontal traverse adjacent to each other, a connection solidifying in an unfolded position, after immobilization of said reinforcement by a locking means.   
   
   
       11 . Folding structure according to  claim 6 , wherein said cross-piece pivotally cooperates with a junction piece at a level of a pivot. 
   
   
       12 . Folding structure according to  claim 11 , wherein said junction piece reinforces, from outside, a junction of said two segments of a horizontal traverse adjacent to each other, said junction piece being immobilized through immobiliation means on said two segments. 
   
   
       13 . Folding structure, according to  claim 1 , further comprising:
 a receiving means, at a level of at least one upright for receiving signalization means, being comprised of a rabbet receiving a light garland forming said signalization means, or receiving a piping, and a lateral occultation means.   
   
   
       14 . Folding structure according to  claim 1 , further comprising:
 a locking means of at least one longitudinal member-hook, articulated around an upper articulation of at least one articulated crisscross, provided at a lower portion thereof with a hook, said hook cooperating with a trunnion, a lower articulation being situated on a vertical of said upper articulation.   
   
   
       15 . An upright for forming the folding structure of  claim 1 , said upright comprising:
 an upper element;   a lower element sliding with respect to said upper element, being integral therewith; and   an unfolding or re-folding means incorporated therein, said upper element, comprising a guiding means, over at least a portion of a length thereof, said guiding means being formed of a slide and cooperating with rolling means formed of a carriage and sliding inside the carriage, said rolling means having ends of longitudinal members mounted thereon in an articulated manner.
