Pool e.g. swimming pool, covering device, has pole unit disposed between upper convex shape flexible cover forming unit and lower concave shape flexible cover forming unit, and stressing unit to stress circumference of cover forming units

摘要

The device has an upper convex shape flexible cover forming unit (1), a lower concave shape flexible cover forming unit (2), and a pole unit (3) disposed between the upper and lower cover forming units. The units (1, 2) are connected to each other on a part of their circumference. The pole unit exerts a stress between the units (1, 2). A stressing unit (20) stresses the circumference of the cover forming units. An independent claim is also included for an installation constituted of a pool and a pool covering device.
