ABSTRACT:
Apparatus comprising a base member fixed to a swimming pool wall in operative proximity to a skimmer inlet opening and having a permanent magnet plate embedded therein, and a bracket member having an iron plate embedded therein. An elongated deflector, carried by the bracket member, deflects and guides surface-water-borne dirt, leaves, pollen and other debris via circulating pool water into the skimmer inlet opening. The attractive force exerted by the permanent magnet plate towards the iron plate allows adjustable and fixed relative positioning, vertically, laterally and/or radially, of the bracket member with respect to the base member, and, hence, the deflector. The bracket member and deflector have cooperating means to allow lateral angular positioning of the deflector. Appropriate radial positioning of the deflector creates an inherent force component causing subsurface dirt, leaves, pollen and other debris to rise to the surface to be carried into the skimmer inlet opening. Impact from a person falling upon the deflector, of full-floatation, impact-absorbing material, causes the bracket member to break away without consequent injury to such person and with the bracket member and deflector floating upon the water.
