Patent ID: 7290553

Claim:
A folding modular structure for a tent comprising: a plurality of tubular profile bars of a size suitable for supporting a canvas thereon, said plurality of tubular profile bars comprising a first plurality of bars forming a first arch and a second plurality of bars forming a second arch, said first arch facing said second arch and connected by at least two purlins, one of said at least two purlins being a ridge purlin, said ridge purlin formed of a pair of profile bars, one of said pair of profile bars of said ridge purlin connected by a first ridge member to said first arch, another of said pair of profile bars connected by a second ridge member to said second arch, each of said first and second ridge members comprising a first pivoting means for pivoting the profile bar relative to the ridge member along an axis perpendicular to a plane of the respective arch, each of said first and second ridge members further comprising an indexing means for angularly limiting the pivoting of the profile bar, each of said first and second ridge members comprising a second pivoting means for hinging an end of the profile bar along a transversal axis parallel to the plane of the respective arch such that said pair of profile bars folds inwardly from a longitudinally aligned position to a position parallel to said first and second arches, said ridge purlin comprising an encasing means for immobilizing an axial pivoting of one of said pair of profile bars with respect to the other of said pair of profile bars relative to an angular position defined by said indexing means.
