Abstract
An openable and closable opening is formed in a pool cover, adjacent to or at the pool cover leading edge, and a mechanism for enabling opening and closing of the cover opening is provided. Upon opening of the cover opening, water, which may accumulate on the pool cover when the cover is extended over the pool, is able to drain through the cover opening into the pool during retraction of the cover. Upon closing of the cover opening, the cover may be smoothly and evenly extended so as to cover, and retracted so as to uncover the pool. A mesh bag depends from the sides of the cover adjacent the cover opening, so as to prevent objects from falling through the opened cover opening into the pool. A foam strip is secured to the mesh bag, so as to enable the section of the cover which includes the opening therein to float if the cover contacts the water in the pool, so as to prevent such water from being scooped onto the cover during retraction thereof.
