  • Patent number: 5303527
    Abstract: A removable support apparatus for supporting a swimming pool cover employs adjustable frame assemblies capable of spanning between opposite edges at opposite sides of the pool. Each frame assembly includes a pair of separate frame members placed in side-by-side relation to one another so that together they define the overall length of the frame assembly. The frame members are displacable longitudinally relative to one another to adjust the overall length of the frame assembly to match the distance between the opposite edges of the pool so that the frame assembly can fit across the pool between its opposite edges. Each frame assembly also includes an end support member attached to the outer end of each frame member and supporting the frame member from one of the opposite edges of the pool.
