ABSTRACT:
A cover devised to be positioned over and to overlay an opening contiguous to a swimming pool such as a stairwell opening. The cover is a preformed modular plastic unit. The cover may comprise a single molded piece or a plurality of pre-molded sections that are secured side-by-side to form a rigid unit. The cover is preferably slightly domed and provided with integrally formed strengthening ribs or channels. The dome shape facilitates flowing of water which may accumulate on the cover surface, to the rear and to the sides of the cover. Suitable means, such as pliable plastic water filled tubes, or other hold down means, function to retain the cover in place when in position, against undesirable dislocation from its covering position. The cover also facilitates the installation of a flexible vinyl liner in a swimming pool by providing means to hold the liner over, and to seal, the opening during the installation of the liner.
