ABSTRACT:
An umbrella pool cover frame has a center post, e.g., PVC pipe, that rests on a base disk on the floor of the pool. An adjustable center support is positioned partway up the center post and held in place, e.g., with a pin. A top support disk is fitted to the top of the center post. The center and top support disks have bores to receive ends of support legs or ribs. In one embodiment, sixteen long support legs extend from ground to respective bores in the top disk, and sixteen short support legs extend between respective bores in the center disk and receptacles in the associated support legs. The weight of the frame and the cover is supported both on the center post and on the ground at the ends of the long support legs. For an oblong pool, there can be more than one center support post, and horizontal members or ribs that join the two associated top support disks. The top support disk and the base disk have protective mats to protect the pool floor and the pool cover. The support legs can be extruded aluminum tubing.
