A system for adjusting surface level, including a moveable surface, at least two structures adapted to be disposed between and coupled to the moveable surface and a fixed surface, a single force transfer mechanism configured to be coupled to the at least one of the at least two structures for displacement of the moveable surface relative to the fixed surface.

The invention relates to an actuating device for an approximately horizontal mobile platform that is able to be set in movement in a vertical direction between a high position and a low position, and having a frame supporting the platform, said actuating device having at least one rigid chain actuated by at least one motor secured to the frame, and a guide member for guiding the rigid chain between a position substantially extended in the direction of the ground and a position substantially stowed parallel to the frame.

A swimming pool including a movable bottom, side walls and a movable platform defining the bathing volume. The platform, actuated by a system, passes from a submerged position to a raised position in the air to close the bathing volume. A peripheral flow conduit, arranged at the periphery of the bathing volume and the side walls, has an upper mouth system and a lower mouth system communicating with the bathing volume. The pool has a main water tank containing water from the overflow, a secondary tank for collecting the overflow, a pump system linking buffer tanks and continuously supplying the overflow, and a water collection system. The water collection system extends the periphery of the bathing volume and passes from a low position when the platform is static to a high position when the platform moves, providing a peripheral anti-overflow barrier and constituting the upper mouth system.
