Abstract

A structure comprising at least three essentially rigid legs, each having a top end, and a bottom end, with at least two connecting elements fitted on each leg and at least three elongate braces each having a first end and a second end and being fitted with at least four anchoring sites. Each brace is connected with two adjacent legs, and at least one of the anchoring sites is directly coupled with a respective connecting element of one adjacent leg, and at least one other of the anchoring sites is coupled via a tensioning member to another respective connecting element of the other adjacent leg.

1 . A structure comprising at least three essentially rigid legs located about a center of the structure, each leg having a top end and a bottom end, with at least two connecting elements fitted on each leg; at least three elongate braces each having a first end and a second end and being fitted with at least four anchoring sites; each brace being connected with to two adjacent legs, where at least one of said sites is directly coupled with a respective connecting element of one adjacent leg, and at least on other of said sites being coupled via a tensioning member to another respective connecting element of the other adjacent leg.  
     
     
         2 . A structure according to  claim 1 , wherein the direct coupling of the anchoring sites with the connecting elements is pivotal.  
     
     
         3 . A structure according to  claim 1 , wherein the tensioning members provide an inward force on the top ends causing them to approach the center of the structure.  
     
     
         4 . A structure according to  claim 1 , wherein the ends of the legs are connected by an additional tensioning member.  
     
     
         5 . A structure according to  claim 4 , wherein tension in the additional tensioning member provides the ends of the legs with a force countering the inward force.  
     
     
         6 . A structure according to  claim 5 , wherein the tension in the additional tensioning member is adjustable.  
     
     
         7 . A structure according to  claim 1 , wherein anchoring sites on adjacent braces are attached to prevent the augmentation of the angle between the braces.  
     
     
         8 . A structure according to  claim 7 , wherein anchoring sites on adjacent braces are attached via a tensioning member.  
     
     
         9 . A structure according to  claim 1 , wherein the bottom ends of the legs are capable of being attached to the supporting surface.  
     
     
         10 . A structure according to  claim 1 , wherein the top ends of the legs extend towards a center of the structure.  
     
     
         11 . A structure according to  claim 10 , wherein the extended upper ends are capable of supporting a stabilizing weight to further stabilize the structure.  
     
     
         12 . A structure according to  claim 10 , wherein the extended upper ends are capable of supporting a canopy.  
     
     
         13 . A structure according to  claim 1 , wherein the structure is a tent frame or a sukkah.  
     
     
         14 . A structure according to  claim 1 , wherein all components remain connected to respective other components also at the collapsed state of the structure.  
     
     
         15 . A structure according to  claim 1 , wherein the tensioning members provide an inward force on the top ends of the legs, causing them to approach the center of the structure while causing bottom ends of the legs to depart from the center of the structure.  
     
     
         16 . A structure according to  claim 1 , wherein at least one brace is directly coupled to a respective leg at a portion of the brace other then its end and where said braces is coupled to the respective leg by a tension member extending between a portion of the brace and a portion of the respective leg below the point of direct coupling with said brace.  
     
     
         17 . A structure according to  claim 1 , wherein two or more braces are coupled to the respective legs with a first tensioning member extending between a portion of the brace and a portion of the respective leg below the point of direct coupling with said brace and a second tensioning member extending between a portion of the brace and a portion of the respective leg above the point of direct coupling with said brace.  
     
     
         18 . A structure according to  claim 1 , wherein tensioning members extending from two intersecting braces towards a portion of a leg are coupled to the leg at the same site.
