20 parti, sunt asamblate cate un assembled upper distance piece (MG); the mode of operation / assembly follows the stages as shown below: In the initial stage . the assembled left-side runway (A), the assembled right-side runway (B) and the driving unit (C) are mounted in the premises - on the walls, columns, etc.; the motor (7) being turned off, the polygonal-headed axle rotates freely; the Gall chains, (12 and 12’) are assembled on the wheels (10 and 5, respectively 11 and 5’) so that the lower work driving arms (23 and 23’) are in the proximity of the Gall chain sprocket wheels (10 and respectively 11 ) on the side facing the runways (2 and respectively 2’) ; In the second stage . simultaneously, through the two slots that make the horizontal branches of the letter“F” in the storage panels (3 and 3’), the assembled lower panel (E) is inserted: both on the left-side storage panel (3) and the right-side storage panel (3’), the bearings (21) on the long bolt (17) are first inserted in the slot (a), then the bearings (21) on the short bolt (16) are inserted in the slot (as); owing to the fact that Dis > p (Fig. 6”, Fig. 3.1 , Fig. 4.1 ), the assembled lower panel . E, will have an oblique position; owing to the b gravitational fall angle of the runways in the two storage panels (3 and 3’) the assembled lower panel, E, will slide along the slots and will capture the lower work driving arms (23 respectively 23) in the drive slots (cm. respectively cm’) of the small face plates (24 and 24’), which will glide freely in the slots (cm and respectively cm’); the assembled intermediary panels (F), are inserted one by one, in the same manner and, at the end, the assembled upper panel (G) is inserted (Fig. 2a, Fig. 2b); In the third stage . by letting the assembled lower panel (E) glide freely, through its own weight, in the vertical runways (2 and respectively 2’), as soon as the downward movement of the assembled lower panel (E), allows it, the first assembled intermediary panel (F) positions itself by gliding with the two assembled intermediary distance pieces (MF), at the ends, on the sliding blocks (20) of the assembled lower panel (E); owing to the springs (19), the sliding blocks (20) keep the assembled intermediary panel (F) away from the orientation bolts (15) that are assembled in the upper part of the assembled lower panel (E) (Fig. 5 and Fig. 6”) at the Lmd + dep > hpan+hb distance; as soon as the downward movement of the first

21 assembled intermediary panel (F) allows it, the next, assembled intermediary panel (F) positions itself, by gliding with the two assembled intermediary distance pieces (MF) at the ends, on the sliding blocks (20) of the assembled lower panel (E); owing to the weight of the two previous panels, the first assembled intermediary panel (E) enters, with the unfair holes (o) in the orientation bolts (15) that are assembled on the upper part of the previous panel; but, owing to the springs (19) of the previous assembled distance piece, the sliding blocks (20) keep the next assembled intermediary panel (F) away from the orientation bolts (15) that are assembled in the upper part of the previous assembled panel at the same Lmd + dep > hpan + hb distance; when the assembled upper panel. (G) gets in vertical position, the special motor (7) starts and, through the assembly of pieces of the driving unit (C), actuates the Gall chains (12 and 12’) and the upper work driving arms (13 and respectively 13’), thus coming into contact with and pushing down, on the F direction (Fig. 12.1), the coupler jaws (26) of the assembled upper distance piece (MG) to the point where the springs (20) of this last distance piece are completely compressed to ensure i) the orientation of the assembled upper panel (G) in the orientation bolts (15) of the one before last panel and ii) the tightening of the entire retractable wall, while complying with the alpha > 0 (at least 2- 3 cm) condition (Fig.12), so that the last bearing does not come out from the vertical part of the slot (as and as’) in the storage panels (3 and 3’), in other words the vertical part of e size of the slot (a and a’); in this position, between the work driving arms (23 and respectively 23’) and the shoulder of the (cm and respectively cm’) slots of the small face plates (24 and 24’) a clearance of a few centimetres remains, and the motor (7) stops through electronic command; for the retracting of the modular wall, the engine (7) is turned on, the Gall chains (12 and 12’) are actuated simultaneously, the upper work driving arms (13 and 13’) stop pushing onto the coupler jaws (26) of the assembled upper distance piece (MG), releasing the springs (19), and thus allowing the sliding block (20) to move the assembled upper panel (F), which goes out of the orientation bolts (15); the lower driving arms (23 and 23’) get to the shoulders of the drive slots (cm and respectively cm’)

22 and then drive all the above panels in an upward movement; when the assembled upper panel (G), enters the left-side storage panel (3) and rightside storage panel (3’), the next assembled intermediary panel (F), in its turn, comes out of the orientation bolts (15) of the intermediary panel underneath it, thus being able to enter the left-side (3) and right-side (3’) storage panels; the retracting of all the panels in the upper part of the retractable wall ends when the bearings (21) on the long bolts (17) of the assembled lower panel (E) reach the dfin > 0 distance from the peak (b) between the upper part of the lower slot of the letter“F” of the left-side storage panels (3) and right-side storage panels (3’).
