Abstract (en)
A swimming pool floor (20), intended to be fitted in a pool having a wave machine, is movable between a lowered position and a raised position. In the lowered position the pool floor (20) is submerged and lies on or adjacent the base (10) of the pool. In the raised position one end of the floor (20) is lifted and registers with a fixed pool edge (18) to simulate a beach, over which the waves from the wave machine break. A pair of piston and cylinder devices (28), driven by water under pressure, operate through links (32,34) to move the floor (20) between its raised and lowered positions.
