Abstract

Abstract A pool cover in sheet form is provided with tie members which are connectable to tie-anchoring members which are secured to the side walls of the pool just below the coping. The cover is provided with depending skirt portions around its edges which extend downwardly into the water and serve to prevent the wind from getting beneath the cover to blow it out of position.
