Description

Each platform consists of a platform {s 1 with a rack 2 with the rear 3 pointing downwards and four front lugs with support rollers 5 and supporting rollers 6.

With their support rollers, the platforms 5 rest on rails 7 made in the walls of the hall.

The first platform is provided with loops 8 (in front) and 9 (in the rear) for fastening the pull ropes, respectively, 10 and 11.

The platforms are equipped with rows of folding chairs 12 for spectators equipped with folding backrests 13 and seats 14.

The rollers 5 are supported on the wall guides 7 supported by the rollers 6, in the extended position of the platform form a stepped floor above the stationary horizontal floor 15 of the hall (see Figs. 2 and 3).

The mechanism for moving the platforms is made in a double-drum winder with drums 16 and 17 and gearmotor 18 and is located behind the rear wall of hall 19.

To extend the pads, rope 10 is held around rollers 20 and 21 located in the front of the room, for example, under the stage.

In a shifted position, platforms are located at the rear of the hall, for example, under balcony 22.

From the shifted position (Fig. 5), the platforms are moved apart by a winch by the ropes 10, the ends of which are fastened by the loops 8 and, through the dead rollers 20, 21 tons, advance the first platform. In this case, the sites move on rollers 5 but guides 7 in the walls of the hall. Coming out from under the second platform, the first padding, with its support roller 6, grabs the second platform behind the front ledge 4 and carries it along.

This continues until the full separation of the pads to the position shown in FIG. 2 and 3.

Then, the engine 18 is turned off, the reels 16 and 17 of the vehicle are retained, the platforms are fixed in the guides, the ropes 10 are removed from the loops 8 and retracted in the recesses near the rollers 20, and the backs of the 13 chairs 12 are raised. The hall is transformed into a visual for showing films or for stage performances.

During the reverse transformation of the hall (Fig. 4), the winch engine 18 is turned on in the opposite direction, the first platform for the rope 11 t is back, the backs of the 13 chairs 12 by the projections 4 of each next platform are tilted forward, the first platform rolls under the second and the roller 6 by the ledge 3 for a second platform, etc.

In the shifted position, the platforms are located under the balcony 22 and can be closed from the hall, for example, with a taller or split wall.

In the assembled position, the plats are fixed in the guides, and the drums 16 and 17 are the stopper of the vehicle.
