Claim:
A collapsible furniture structure, comprising: a support having two parallel side boards that are set a distance apart, that are of approximately rectangular shape, and have two bottom corners, front and rear, and two top corners, front and rear; a pivoting frame, of approximately rectangular shape, that has a rear end part engaged between said side boards and that pivots on said side boards between an approximately vertical folded position and an approximately horizontal down position in which the frame is opened in the forward direction; at least one crossmember perpendicular to and fixed to said side boards and intended to be in contact with a floor or with a wall and comprising means for fixing said at least one crossmember to the floor or to the wall; a transverse hinge pin extending perpendicularly to said side boards and mounted on said frame, ends of said hinge pin pivoting on said side boards in an area close to said front top corners, said pivoting frame extending towards the rear past said hinge pin; and a transverse anti-torsion reinforcing bar perpendicular to and connected to said side boards and located in an area situated underneath, adjacent to and slightly forward of said hinge pin so as to optimize the resistance, to form an end-of-travel stop for the pivoting frame when the frame is in the folded position and to prevent the pivoting frame dropping down when the frame is in the down position.
