The wall (1) has support rollers (5) at its base running on a track (11). The track has a rail pivoting on a lever (18) about an axis (10) approximately in the mid-range of movement (T1) of the wall between the closed (K) and open (A) positions. The height of the wall underside (H1) is the same in the open and closed positions. A multilever roof mechanism connected to the frame at the roof supports the wall top and moves it between the open and closed positions. The levers open and tilt the wall by moving the top a greater distance outwards than the base. |
