Abstract: A swimming pool, of the type having a sectionally constructed wall extending about and supporting a plastic liner, incorporates in the wall a capability of forming a wide variety of swimming pools of different shapes and sizes. Disclosed is a wall system which basically comprises a relatively small number of different types of sections. Each section has a flat web and side flanges disposed at selected obtuse or acute angles to the plane of the web. The angles incorporated in each section differ from those of the remaining sections. In this way, by abutting against each other selected sections, and by utilizing a selected number of such sections along different portions of the periphery of a swimming pool, it becomes possible to provide an almost infinite variety of swimming pool shapes and sizes.

Abstract: A patio pool having an outer wall fixedly mounted on ground level undisturbed earth and an inner wall fixedly mounted to undisturbed earth on the bottom of an excavation, the inner wall extending upward from the excavation to a height such that the top edge thereof is at the same level as the top edge of the outer wall thereby providing a pool whose total depth is partly a result of the excavation depth and partly due to the wall portion extending above ground level, the pool has struts fixedly secured to the inner wall for stabilizing the total wall structure, and a filler material positioned within the space between the inner and outer wall and below a plurality of deck slats connecting the top edges of the inner and outer walls for stabilizing the wall construction.
