Abstract (en)
1. Tiered stand, particularly intended for the arrangement of persons either to photograph them or to allow them to attend an entertainment, a conference or other events, of the type comprising a frame (1) which is mounted on wheels (2) and provided with hitching means (3), a first group of so-called upper steps (4) mounted rigidly on the frame, and a second group of so-called lower steps (5) articulated on the first group about a horizontal axis (6) parallel to the steps of the upper and lower groups, it being possible for the lower group (5), by tilting about the axis, to be folded and fitted into the upper group (4) in accordance with a so-called travelling position or, alternatively, opened out in order to adopt a position of use, characterized in that each of the said upper (4) and lower (5) groups of steps comprises a group of so-called outer steps having a hollow prismatic structure, and in that this group of so-called outer steps serves to accommodate at least one group (7, 8 etc...) of similarly shaped so-called inner steps which can be drawn out therefrom by sliding, as a result of which the surface of use of the outer steps of the upper group and lower group can be doubled by drawing out the inner steps.
