Abstract

A collapsible dome includes two or more arches of larger radius than half of the diameter of the pool which are therefore lower and provide a consequently lower structure, preferably of arcuated shape. Arches are pivotably attached on one end to the first support base, mounted to the pool's edge, and on the other to the second support base. Second support base is slidably hung upon a support guide bar which is mounted on the pool's edge with one end opposite the first support base and a membrane cover attached to each arch and tensioned after set up to the pool's edge. While the membrane is not fastened to the pool's edge, one side of the collapsible dome can easily be shifted along the support guide bar. Before collapsing the dome, the second support base should be shifted along the support guide bar in the appropriate direction to decrease the circumference between the first and second support bases. The arches, having a larger radius than the pool, would otherwise collapse into the pool instead of onto the pool's edge. When the dome is used on pools with shape different than round like oval or rectangular, shifting of both support bases along the pool's edge before collapsing of the dome is required to assure collapsing of the dome on or behind the pool's edge. Domes having only two arches are quickly and easily attached to the pool's edge by pivotable attaching components, which include two cups into which the ends of the arches are put by means of slip joint assemblies, bound by a cord that permits pivotal movement to the base support.
