Claim 1
Independent Claim
280 words
A wall construction for a swimming pool, comprising: a molded plastic and fiberglass wall section having an open boxlike configuration, said wall section having an enlarged bottom panel which is normally disposed in a substantially vertical orientation, the outer surface of said bottom panel comprising the front side of said wall section; said wall section including a coping integrally formed with and extending along the upper edge of said panel, said wall section also including an anchoring flange integral with and extending along the lower edge of said panel, said coping and said anchoring flange each projecting rearwardly of said panel; said wall section further including a pair of end walls integral with and extending along the opposite vertical edges of said panel, saId end walls projecting rearwardly from said panel and extending vertically between said coping and said anchoring flange; a plurality of upright and substantially parallel reinforcing ribs fixedly secured to said wall section, said ribs being laterally spaced from one another and fixedly secured to the rear surface of said panel, each of said ribs being relatively narrow and occupying a relatively minor part of said rear surface; each of said ribs having an opening extending therethrough perpendicular to the elongated length of said rib, said opening extending in a direction substantially parallel with said rear surface, the openings as formed in said plurality of ribs being substantially aligned; and elongated rigid rod means received within said plurality of openings and extending between said plurality of ribs, said rod means being spaced rearwardly of said rear surface, whereby said rod means is adapted to be embedded within concrete or the like when said wall construction is installed.
Claim 2
Dependent Claim
280 words
