The present invention relates generally to the field of covers or enclosures for pools, spas or hot tubs. More specifically, the present invention relates to an inflatable cover or enclosure having an inflatable body. The cover includes a side surface with an integrated retaining aid, a valve and an integrated pump. The cover or enclosure can be placed on top of a pool, hot tub or spa, or underneath an existing cover and can then be inflated to a shape such as a convex dome-like shape. Once inflated, the cover prevents debris or water from accumulating on the cover.

A sheet of flexible material can be deployed or stored by unfurling or furling the sheet using one or more inflatables. After the sheet is deployed to, for example, cover a load on a flatbed trailer, the inflatable can be deflated for storage. A sheet that has been removed from the load can be stored by placing an inflatable along an edge of the sheet. The inflatable is pressurized, and the sheet is furled onto the inflatable by rolling the inflatable. The inflatable is deflated and rolled up with the sheet for storage.

A flexible and waterproof containment tube sits within a basin and prevents objects from entering the basin. When placed inside the basin, the containment tube is filled with a filling fluid. The dimensions of the containment tube are similar to that of the basin such that the containment tube fits within and fills substantially all of the basin. The outward hoop stress of the side portion against the walls of the basin evenly distribute pressure and protect the basin from damage, such as debris, rain or flood, water, or other objects.

A protective pool assembly for protecting a pool from external debris or contamination. The protective pool assembly comprises a flexible cover and a bladder. The flexible cover comprises a top layer configured to resist weather. The flexible cover is attached to or rests on and protects the bladder. The bladder rests on a bottom layer of the flexible cover, or directly on the surface of the water. The bladder is inflatable via an air valve to expand the bladder in a dome-like shape. The flexible cover is pushed upward into the dome-like shape so that external debris, rain, snow, and ice shed off of the flexible cover. A skirt extends from a perimeter of the flexible cover to further direct the debris or contaminates over the side of the pool. A plurality of securing elements are used to secure the protective pool assembly in place over the pool.

A pool cover for an aboveground swimming pool, the cover formed with an integrated inflatable and deflatable pocket centrally positioned on the cover. The cover is made of waterproof and durable vinyl PVC knife-coated material.

In one preferred form there is provide a pool cover arrangement (10) comprising: a body (12) having a first set of cells (24) and a second set of cells (26). The first set of cells (24) provide a first area (35) for floating on water. The first area (35) comprises the forward facing areas (27) of the first set of cells (24). The second set of cells (26) are spaced away from the forward facing areas (27), so as to sit above the water, when the first set of cells (24) sit on the water. In other preferred forms ventilation holes and layers are provided.

A floating module for the reduction of losses by evaporation in aqueous-based liquids which includes two hexagonal, watertight, hollow cells and configured to accommodate an internal ballast; and a perimeter wing arranged on the horizontal axis of the floating module.
