Abstract: A lightweight frame capable of being hand-assembled and particularly adapted for supporting a cover sheet over a pool or spa, or for providing a temporary shelter. The frame includes at least one central hub having a plurality of ribs extending from the hub to the edge of the pool or spa. Each rib includes a plurality of segments that are connected end-to-end, there being an end member which holds the rib against the edge of the pool or spa. The frame is generally dome shaped above the pool or spa and held in place by forces extending along the length of the ribs toward the edge of the pool or spa. When used as a temporary shelter, the end members include pointed portions that can be inserted into the ground. The end members can include portions to which a cover sheet placed over the frame can be fastened in order to secure the cover sheet. The frame can include any number of segments depending upon the ultimate size desired, the height of the frame being dependent upon the length of the ribs.

Abstract: This pool cover utilizes multiple, laterally displaced air compartments which are fixed in location with respect to each other, and are integral portions of the cover. The air compartments may be interleaved by having laterally overlapping portions in order to minimize sagging which may result if any air compartment were to have an air leak. The cover can include a removable exterior portion which is exposed, and an interior portion containing the air compartments which are in contact with the pool surface. This allows easy removal of the top portion of the cover for cleaning and for examining individual air compartments.
