Patent ID: 8185990

Claim:
A swimming pool brush, comprising: a brush head having a top wall and a bottom wall; an elongate handle having a leading end adapted to engage said brush head and a proximal end adapted to be engaged by a user of said swimming pool brush; at least one aperture formed in said brush head; a plurality of bristles secured to said bottom wall in depending relation thereto and in surrounding relation to said at least one aperture; a first plurality of clips formed integrally with said top wall on a first side of said at least one aperture; a second plurality of clips formed integrally with said top wall on a second side of said at least one aperture; a hydrofoil plate having a first longitudinally-extending edge adapted to be selectively hingedly engaged by said first plurality of clips or said second plurality of clips; said hydrofoil plate having a first, extended position when said brush head is immersed in water and pushed downwardly against a substantially vertical swimming pool sidewall; said first position being a position of rotational adjustment where said hydrofoil plate is positioned in a plane that is substantially perpendicular to said swimming pool side wall; said hydrofoil plate having a second, retracted position when said brush head is pulled upwardly against a swimming pool sidewall; said second position being a position of rotational adjustment where said hydrofoil plate is positioned in a plane that is substantially parallel to said swimming pool sidewall; said hydrofoil plate, when in said first position, being pushed by water in said swimming pool towards said swimming pool sidewall, thereby increasing pressure of said bristles against said sidewall; said at least one aperture being operative to reduce a venturi effect created by water flowing over said hydrofoil plate when said hydrofoil plate is in said first position; said at least one aperture, when said hydrofoil plate is in said second position, creating a venturi effect that pushes said bristles away from said swimming pool sidewall.
