A lifesaving system for a swimming pool includes a plurality of lifesaving modules. Each module includes a platform and is stowable in a standby configuration under a surface of water in the pool. The module is deployable to rise to a surface of water in the pool beneath a swimmer in distress so as to support the swimmer on the platform.

A variable depth swimming pool/spa includes deck and a bottom, wherein the deck is movable relative to the bottom of a variable depth swimming pool/spa. The movable deck can be connected to the bottom of the variable depth swimming pool/spa via one or several legs which are rotatingly connected to the movable deck and slidingly connected to the bottom of the swimming pool/spa. The rotational displacement of the legs results in the vertical displacement of the movable deck. The legs may be connected to synchronizing arms that can interact with a synchronizing drive to coordinate the movement of a first leg with a second leg. Further, flow features control the flow of water from above the movable deck to between the movable deck and the bottom of the swimming pool/spa.

A swim training system may include a swimming pool including a pool frame. The pool frame defines a water containment void. A height-adjustable floor is suspended within the water containment void. The swim training system may be used to train student to swim.

Pool protection systems are disclosed. In one particular embodiment, a pool protection system may include a platform fitted in a pool, oriented substantially parallel to a surface of water in the pool, and configured to move vertically in the pool; one or more motors mechanically connected to the platform; and a controller in communication with the one or more motors.

The present invention relates to an extendable container for fluids with variable containment volume and dimensions, which comprises one or more elements independent and capable of relative movement among themselves.

The invention relates to an adjustable swimming pool floor system (40). In addition, the invention relates to a swimming pool (5) comprising such an adjustable pool floor system. Furthermore, the invention relates to a method for installing the hydraulic system (1) in a swimming pool. The invention also relates to a hydraulic system for use in an adjustable swimming pool floor system.

A mobile-bottom device for swimming pools or hollow cavities comprising a frame (1) fixed to a meshed framework (2) comprising first profile sections (20) running in a first direction and belonging to at least one first plane P1 referred to as the upper plane, and second profile sections (21) superposed on the first profile sections (20) and running in a second direction preferably perpendicular to the first direction and belonging to a second plane P2 referred to as the lower plane and different from the first plane P1, means for raising and lowering the frame and the framework, means for motorizing the raising and lowering means. According to the invention, said first and second profile sections (20, 21) have a U-shaped cross section having a first face (201) and a second face (202) that are mutually parallel and connected by a third Lace (203) of height H, the first face and the second face being provided with openings organized in sequences along the length L of the profile section, each sequence comprising a series of N1 openings (2010) which are aligned and equidistant by a distance d1, said series being juxtaposed with a series of N2 openings (2011) which are aligned and equidistant by a distance d2 greater than d1, the third face (203) being provided with two rows of three openings (2030) which are aligned and equidistant by a distance d1 positioned facing the openings (2010) of the first and second faces, and with an elongate opening (2031) along the height H and surrounded by at least four openings (2032) which are aligned with the two rows of openings (2030); each end of a profile section (20, 21) comprises openings on each face (201, 202, 203), and said profile sections are bolted together.

The anti-drowning system for use with a pool is a safety structure. The anti-drowning system for use with a pool comprises a mesh structure, a plurality of worm drives, and a pool. The pool is a manmade structure that is defined elsewhere in this disclosure. The pool further comprises a bed. The mesh structure and the plurality of worm drives forms a safety structure for the pool. The mesh structure is a fluid permeable structure that inserts into the pool. The plurality of worm drives attach to the mesh structure such that the plurality of worm drives raises and lower the mesh structure within the pool. The mesh structure forms a horizontally oriented supporting surface. The plurality of worm drives adjusts the elevation of the mesh structure such that the mesh structure can lift a distressed swimmer out of the pool.

A variable depth swimming pool/spa can comprise a movable deck and a bottom. The movable deck can be movable relative to the bottom of a variable depth swimming pool/spa to provide for a variable depth of the portion of pool/spa that is accessible to a pool/spa user. The movable deck can be connected to the bottom of the variable depth swimming pool/spa via one or several legs. The one or several legs can be rotatingly connected to the movable deck and can be slidingly connected to the bottom of the swimming pool/spa. The rotational displacement of the legs can result in the vertical displacement of the movable deck. The legs can be connected to synchronizing arms that can interact with a synchronizing drive to coordinate the movement of a first leg with a second leg.
