Rigid cover assignment for swimming pool or basin

A rigid cover arrangement for a swimming pool having a basin (1), said cover arrangement being movable vertically inside the basin (1) between two extreme positions, one of said extreme positions being a bottom (7) and the other of said extreme positions being the surface of the pool, said rigid cover arrangement comprising:

• sealing shutters (70) movably supported on a support structure (9) for movement between an open position and a closed position;
• said support structure (9) being planar and rigid and forming a plurality of partitions, each of said partitions being sealable by at least one of said shutters (70);
• and
• displacement means positioning and maintaining the supporting structure (9) in at least a third position situated between said extreme positions;
• said support structure (9) comprising a plurality of scissor elements (17), each of said scissor elements (17) having two articulated legs (19, 19'), said articulated legs each having a lower end or a base supported at the bottom (7) of said basin (1) on movable members (51, 53), respectively situated in the plane of said bottom (1);
• said movable members (51, 53) including two opposite constructions (100, 100') disposed opposite and parallel to one another and extending in one of the longitudinal or transverse directions of said basin (1);
• and
• parallel carriages (98, 98') fixed on and extending perpendicular to the constructions (100, 100') and alternate relative to each other so that two adjacent carriages (98, 98') are associated with said two opposite constructions (100, 100'), respective bases of said legs (19, 19') of one and the same scissor element (17) being supported in an articulated manner on said two adjacent carriages (98, 98') so that all relative parallel displacement (d) of the two constructions (100, 100') causes an identical displacement (d) of the bases of the legs (19, 19').

• and
• displacement means positioning and maintaining said supporting structure (9) in at least a third position situated between said extreme positions.
