Claims
exact text as granted — not AI-modified1 . An apparatus for polishing a surface comprising:
a polishing head comprising a plurality of flap assemblies; and a shaft attached to the plurality of flap assemblies for rotatably driving the polishing head.
2 . The apparatus of claim 1 wherein the flap assembly comprises an upper material layer and a lower material layer with at least one stiffener element between the upper material layer and the lower material layer.
3 . The apparatus of claim 2 wherein the at least one stiffener element is smaller than the upper material layer and the lower material layer such that at least an unsupported length L of the upper material layer and the lower material layer extend outward from the at least one stiffener element.
4 . The apparatus of claim 2 wherein the upper material layer and the lower material layer comprise a microfiber material.
5 . The apparatus of claim 2 wherein the stiffener element comprises a foam material.
6 . The apparatus of claim 1 further comprising a handle assembly acting cooperatively with the shaft to support the polishing head.
7 . The apparatus of claim 6 wherein the handle assembly comprises a housing and a folding handle pivotally attached to the housing.
8 . The apparatus of claim 6 wherein the shaft extends through the handle assembly.
9 . The apparatus of claim 6 further comprising a handle shaft extending through the housing coupled to the shaft.
10 . The apparatus of claim 2 wherein the upper material layer and the lower material layer each have a shape comprising a first width at a first section and a tapering width section.
11 . The apparatus of claim 2 wherein the upper material layer and the lower material layer comprise a main section and a bulbous tip.
12 . The apparatus of claim 2 wherein at least one of the upper material layer and the lower material layer has a cutout extending through the at least one of the upper material layer and the lower material layer.
13 . The apparatus of claim 2 wherein the at least one of the upper material layer and the lower material layer comprises a textured surface.
14 . The apparatus of claim 2 wherein the upper material layer and the lower material layer each comprise an internally arched lower edge.
15 . The apparatus of claim 2 wherein the stiffener element comprises an open cell foam material.Join the waitlist — get patent alerts
