Abstract: 1. Movable covering device for swimming pools, playing grounds and similar structures (3), comprising a roof (2) movable between a lowered position essentially forming a cover in which it substantially overlaps and isolates the first region which can be a swimming pool, a sports ground or a similar structure and a raised position at which the roof overlaps at a certain height the second region (4), which is displaced respective to the first region (3), wherein the roof has first edge (16) disposed from the side adjoining the first region (3) and a second edge (19) opposite to the first edge, the device itself further comprising a structure (12), having pivotable articulation (13) with ground and pivotable articulation (14) with the roof disposed at a distance from the second edge (19), and having a general orientation of movement in the direction from the articulation with ground, in the direction of the second region (4) to the first region (3), when the roof is in its lowered position, characterized in that the device additionally comprises supporting means (18) to support the roof (2) near the second edge (19) with the roof being in the raised position, wherein the roof in the lowered position is disposed at a distance from the supporting means. 2. Device of Claim 1, characterized in that further comprising a lifting means (22, 23) to raise the second edge (19) of the roof in the position, corresponding to the position of the supporting means. 3. Device of Claim 2, characterized in that the lifting means comprise a winch or its analogue (22) associated with a traction cable (23), passing between the roof (2) and position (24), close to the position of the supporting means so as the roof (2), being initially in the lowered position via cable traction could move along the trajectory, when the second edge (19) moves in the direction of the supporting means (18) with pivoting of pivotable structure (12), enabling to raise the first edge of the roof. 4. Device of Claim 3, characterized in that between said position (24) and the roof (2) the cable passes through a carriages (26), moving along substantially vertically oriented trajectory, passing essentially vertical downward from the said position (24). 5. Device of Claim 4, characterized in that the carriages (26) are made enabling free movement along said trajectory. 6. Device of any preceding Claim, characterized in that the pivotable structure is articulated with ground near the edge (6) of the first region (3), adjoining the second region. 7. Device of any preceding Claim, characterized in that the pivotable structure (12) is articulated with the roof (20) from the side of the first edge (16) of the roof with respect to the vertical plane (P), passing through the gravity centre (G) of the roof. 8. Device of any preceding Claim, characterized in that further comprising elastic means (15) providing the displacement of the pivotable structure (12) in the direction of its inclined orientation, corresponding to the lowered position of the roof. 9. Device of any preceding Claim, characterized in that a plane (Q), passing via hinged articulations (13, 14) of the pivotable structures (12) correspondingly with the ground and the roof, is inclined in the direction of the second region (4) with the roof being raised. 10. Device of any preceding Claim, characterized in that the pivotable structure (12) is made curved so as to provide, when the roof in the raised position, orientation the first of two its parts, outgoing from hinged articulation with ground (13) vertically, and orientation of the other part, associated with the first part (17) inclined respective to the second region (4). 11. Device of Claim 10, characterized in that when the roof in the raised position part (17) is inclined towards the second region to an angle, corresponding to the angle of the roof slope. 12. Device of any preceding Claim, characterized in that the roof, being in the lowered position, covers substantially in the isolating manner ground around the first region (3).
