Combination of an outdoor swimming pool and adjustable roof structure

An outdoor swimming pool having a roof structure extending over the pool and over a patio laterally adjacent to the pool, the roof structure being mounted for vertical movement by power operated means between a lowered position, in which it prevents access to the pool, and a raised position in which access to the pool is permitted, securing means being provided along a line extending around the periphery of the pool and adjacent patio, with curtains extending from the roof structure to said securing means, which curtains may be drawn around a selected side or sides of the pool and adjacent patio;

• a plurality of thermal insulating members;
• the roof structure supporting said insulating members which, when the roof structure is in its lowered position are seated on and extend between the peripheral margins bounding the pool;
• the insulating members being so mounted on the roof structure that on movement of the roof structure to its lowered position, lowering movement of the insulating members takes place relative to the roof structure itself;
• a portion of said roof structure being separate from the thus-defined remainder of said roof structure;
• said roof structure portion having at least one of said curtains and at least one of said insulating members associated therewith;
• said roof structure portion being mounted for lateral movement together with said at least one curtain and said at least one insulating member associated therewith when in said raised position.
