First Claim
Patent Images
1. A skirt for an automatic pool cleaning head, comprising:
- at least one flap member including an upper articulating member, said upper articulating member having a distal and proximal end, and having a substantially rectangular shape when viewed from the front and back;
a first hinge having a first axis connecting and interposed between said upper articulating member and the pool cleaning head so as to allow radial motion relative to said pool cleaning head;
a lower articulating member, said lower articulating member having a distal and a proximal end and a substantially rectangular shape when viewed from the front and back; and
a second hinge having a second hinge axis parallel to said first hinge axis and connecting and interposed between said lower articulating member and said upper articulating member.

Abstract
An improved skirt for use with an automatic or robotic pool cleaner head comprising at least one or a row of double-hinged flaps, each of the flaps comprising a receiving member affixed to the pool cleaner head, an upper articulating member pivotally coupled to the receiving member, and a lower articulating member pivotally coupled to the upper articulating member. The pivotally connected members form upper and lower hinges which allow free radial movement upward to, but not beyond, the bottom surface of the pool cleaning head, and further allow the cleaning head to navigate uneven surfaces or pieces of debris while maintaining effective suction.

12. A skirt for an automated pool cleaner head comprising:
-
a receiving member integrally connected to the bottom surface of an automatic pool cleaning head and having a transverse cylindrical aperture; at least one of self-adjusting hinged flaps forming a boundary around a plenum volume of water subjected to vacuum suction, each of said flaps having a fully extended configuration;
an articulated configuration;
an upper articulating member having a proximal and distal end, a transverse cylindrical enlargement at its proximal end pivotally coupled with said receiving member, a transverse cylindrical enlargement at its distal end, and a middle portion between said proximal and distal enlargements; and
a lower articulating member which curves gently outward from the center of the pool cleaner head in the extended configuration and having an integrally formed transverse cylindrical aperture for pivotally coupling with the distal cylindrical enlargement of said upper articulating member.
