Abstract: A movable floor system for a swimming pool, including a structural platform comprising a horizontal frame designed to support a finished covering, the platform being designed to be installed in a cavity acting as the swimming pool. The system includes a lifting mechanism, a plurality of parallel crossmembers fixed within a layer formed by the frame of the platform; and a plurality of carrier pulleys located along outer lateral edges of the frame, the carrier pulleys designed to accommodate a platform-driving cable. The lifting mechanism further includes: a driver; a shaft; first and second drive pulleys situated at the ends of the shaft designed to take at least one platform-driving cable; an attachment to secure at least one cable in the cavity; and means for actuating the drive shaft.
