The ~ s di ~ positi ~ of this type allows ~ in-t no ~ atively to e ~ uiper a ~ alle de ~ pectable de gran ~ e di.mension A affe ~ tation versatile and su~ceptible therefore to be used for ~e~ reunion~ publiqu~s coxrespondant ~ ~es dis~iplines or at de~ a~tivi~sv~ri~e~3.

The room can thus ~very~ tot~leeln~nt cleared for a ~anif ~8~
horizontal station, in which the participants must move from one station to another, while the deployment in grndin~ pel~met to r~ali~er a s~lle of ~pectacle ~e for~e, dimensions and configura~ion ~suitable for the show, whether it 8'~ to position the ~ ~ pec ~ ators pa ~ r ~ ppvrt ~ a scene ~ either ~ act of lcur allow ~ e views ~ a ortive event (tennis, boxing or the like) takes place in the center of 1~ room.

D ~ the ~ i ~ posi-tiLs of this type it is n ~ eessaire of ~ a ~ der const ~ nt ~ the hori ~ ntalite ~ es pl.a ~ es-~ elms.

It is therefore necessary to ensure a par~aite synchronis~tion Qnt ~ e ~ disy ~ itives ~ l ~ v ~ tors including leæ verinæ of ~ a ~ on ~ ë~iter ~oute distribution.

Platform according to one of claims 13, 14 and 15 above, and characterized in that the casing comprises at least one vertical wall capable of constituting the external face of the platform, this face thus being movable with the casing to come to rest on the edge (119) of the platform adjacent in lower position avoiding any solution of continuity between the two neighboring platforms and ensuring the immobilization and mutual blocking of the two adjacent platforms. 19 - Platform according to claim 18, characterized in that the maneuvering casing (115) comprises cleaning means such as a running linear brush along the lower longitudinal edge of said casing and in particular at the base of said vertical wall (118) and rendered capable of sweeping the floor (120) of the reception platform adjacent, especially during the centripetal translation of the seats or rows of seats returning to their accommodation, the brush scraping the floor (120) of the receiving platform thereby automatically removing debris and waste left after the occupation of this platform by the audience. 20 - Method of moving a plurality of platforms movable in height, in accordance with one of claims 13, 14, 15, and the platforms being movable to constitute kill a plain or clear floor or stepped bleachers, the method making it possible to put in active position items of equipment, in particular seats or rows of seats (106) contained in housings (104) inside the said platforms, and the method is characterized in that raising a first platform (102) until the resting plane (115) of the floor of its interior housing (104), arranged laterally, is in the same plane as the floor (1?0) of a second adjacent platform (103) or host platform, we order the implementation of drive units associated with a frame (105) contained in the housing (104) and enclosing said technical equipment in particular seats or rows of seats (106) and by causing thus the horizontal translation of these seats up to them bring them into their final active position on the floor (120) of the reception platform (103), we then resume the elevation movement of the first platform (102) in at the same time causing said casing (105) to rise secured to the platform (102), this casing being held in its extended position, the piece of equipment technical, in particular the seat or seats (106), previously deposited remaining in place by resting on the floor (120) of the second platform (103) or platform reception, after which the frame or casing (105) having been lifted above the highest point of the piece of equipment technical, in particular seats or rows of seats (106), the operation of the motor organs is controlled to cause the retraction of the casing (105) brought back into its housing initial (104) of the first platform (102), the element technical equipment, in particular seats or rows of seats (106) remaining in place on the second platform (103) or reception platform, after retraction of the casing (105), the platforms, respectively the first platform (102) transmitter of the seats or rows of seats and the second platform form (103) or receiving platform for the seats or rows of seats being positioned in height at levels suitable so as to allow the tiering of platforms. 21 - Process according to claim 20 above, further characterized in that after placement of the items of technical equipment, in particular seats or rows of seats (106), on the second platform (103) or receiving platform for the seats, we reproduce the same maneuver so as to position a piece of equipment technical, in particular seats or rows of seats (106a), on said first platform (102) then becoming a platform reception, the row of seats received by the latter platform (102) which has become a host platform being deploy? from a neighboring platform (101). 22 - Process according to claim 21 above, characterized in that after positioning of the elements technical equipment, in particular seats or rows of seats (106), on the platforms (101, 102, 103) these latter are arranged in tiers, each platform comprising a row of seats thus tiered, after which a particular frame a maneuvering casing (105) at least associated with each platform shape is moved outward towards the platform similar shape, in particular in the lower position, said frames in particular said casing (5, 105) by its vertical wall (118) then coming into a bearing position on the edge (119) of the lower adjacent platform (103) thereby ensuring immobilization and mutual blocking of all the platforms.
