Abstract:
1. A flexible plate operable with a submerged swimming pool suction cleaner, the flexible plate comprising: an upper surface and a longitudinally opposing lower surface defining a thickness dimension therebetween; a center portion having an aperture extending longitudinally therethrough for connection to a pool cleaner body, a periphery transversely displaced therefrom, and an intermediate portion therebetween, wherein the thickness dimension is generally uniform from the aperture to an outermost edge of the periphery; and wherein the periphery is curved upwardly relative to the intermediate portion when the flexible plate is placed on a generally flat surface to be cleaned, thus having the intermediate portion contacting the surface to be cleaned and the periphery curved upwardly out of contact therewith at the outermost edge thereof; and a reinforcing element formed for reinforcing the upwardly curved periphery, wherein the reinforcing element includes a rib integrally formed with the upper surface and confined within the outermost edge of the periphery so as not to extend outwardly therebeyond.
