Hinged folding structure (1) consisting of an assembly of elements (2) hinged together by hinge means (3, 4), where each of the elements (2) has at each end a hinge (3, 4) enabling it to be connected to the end of another element (2) across a hinge axis (X, Y), all the pivot pins of the hinges (3, 4) being so constructed that the structure (1) can adopt two extreme positions, namely an unfolded position where the elements (2) are more or less continuous with each other to form an ellipse, and a folded position where the elements (2) are brought together and approximately parallel with each other. The elements (2) and the hinges (3, 4) are connected both to means for controlling the unfolding of the elements (2), and to assistance means for ensuring simultaneity of the unfolding or folding of the elements (2). |
