US 4,746,424 A · Floating swimming pool skimmer

Abstract

A propelled floating swimming pool skimmer having a plurality of angularly related channels with gate means in each of the channels permitting ingress of water and floating leaves and debris into a central area of the body of the device. Nozzles around the periphery of the body propel the unit in desired directions which change automatically in a desired sequence so the unit will cover the entire pool surface. The entrapped leaves and debris are forced downwardly in a spiral path by downwardly-directed jets into a mesh bag in which the leaves and debris may be removed from the pool and, in another form, the leaves and the debris are drawn downwardly through a mesh basket and then through a flexible conduit to the swimming pool vacuum system. Propulsion is accomplished by water under pressure furnished through a flexible conduit to the unit from a suitable source.

Dependent claims

Apparatus for removing bloating debris from the surface of a pool of liquid, comprising:

a body floatable on said pool surface;
propulsion means on said body for driving said body over said pool surface while repeatedly switching the direction of motion of said body over said pool surface among a plurality of preselected directions independently of forces external to said body, and
collecting means on said body for receiving and entrapping debris, said collecting means carried on a central area of said body to cooperate with said propulsion means such that debris approached by said body as said body is driven by said propulsion means over said pool surface along each of said preselected directions is received and entrapped thereby.

A self propelled swimming pool skimmer, comprising a substantially disk-shaped floating body;

propulsion means on said body formed for urging said body over the surface of the swimming pool while repeatedly switching the direction of motion of said body over said pool surface among a plurality of preselected directions independently of forces external to said body,
a plurality of circumferentially spaced radial channels formed in said body and extending below the normal waterline for admitting water and floating debris to a central area of said body , one said channel aligned with each of said preselected directions,
an inclined floating gate pivotally mounted on said body in each of said channels and formed for admitting water and floating debris washing into such channel into said central area and for retaining such debris in said central area against being washed back out through said channels, and
collecting means carried by said body and formed for removing said debris from said central area of said body.
