1. Adjustable swimming pool floor system (40), comprising:
a buoyant pool floor (9) adjustable in a height direction relative to a pool bottom (8) of a swimming pool (5): a hydraulic system (1) comprising:
a hydraulic cylinder (10), comprising a cylinder barrel (11) having a cylinder head (15) and a cylinder cap (17), a piston (16) slideably arranged within the cylinder barrel and a piston rod (12) carried by the piston, whereby a first part of the piston rod (13) extends at an outside of the cylinder barrel beyond the cylinder head; anda sealing arrangement (20) slideably enclosing the first part of the piston rod remote from the cylinder head, whereby the sealing arrangement is connectable with an opening (6) extending through a peripheral pool wall (2) enclosing the swimming pool, from an exterior side (4) to an interior side (3) of the pool wall for extending the first part of the piston rod into an interior of the swimming pool adjacent the interior side of the pool wall, the sealing arrangement preventing leakage of liquid from the swimming pool to the exterior side of the pool wall;the adjustable floor system further comprising:
a movement transfer arrangement (41) connectable at a first end to the first part of the piston rod extendable into the interior of the swimming pool and at a second end to the buoyant pool floor, such that in use movement of the piston rod is transferred to the pool floor and adjustment of the pool floor in the height direction is achieved. |
