Abstract

A brush configured to clean, buff, and polish a surface, comprising a core member having a central axis, a periphery and a sheet of material, the sheet of material comprising closed-cell silicone foam rubber and having a first free end portion. The sheet of material is attached to the core member with the free end portion extending away from the periphery substantially parallel to the central axis of the core member. The core member includes a flat surface adjacent the attachment of the sheet of material. The core member and the sheet of material are configured for relative movement with respect to the surface in at least a first direction. The motion in the first direction causes the free end portion of the sheet of material to contact the surface at a non-zero velocity, and produces at least one of the cleaning, buffing and/or polishing action on the surface.

First claim

What is claimed is:

1. A brush configured to perform at least one of a cleaning, buffing, and polishing action on a surface comprising:
a core member, the core member having a central axis and a periphery;
a sheet of material, the sheet of material being comprised of closed-cell silicone foam rubber and having at least a first free end portion; and
a flexible structural element disposed adjacent the sheet of material and positioned to remain clear of contact with the surface, wherein the flexible structural element is configured to increase a pressure between the sheet of material and the surface being cleaned during the contact by the sheet of material;
wherein the sheet of material is attached to the core member with the at least first free end portion extending away from the periphery of the core member such that the material attachment is substantially parallel to the central axis of the core member;
wherein the core member includes a flat surface adjacent the attachment of said sheet of material; wherein the core member and the sheet of material are configured for relative movement with respect to the surface in at least a first direction;
wherein the motion in the first direction causes the at least first free end portion of the sheet of material to contact the surface at a non-zero velocity; and
wherein the motion of the at least first free end portion of the sheet of material produces at least one of the cleaning, buffing and/or polishing action on the surface.

2. A brush configured to perform at least one of a cleaning, buffing, and polishing action on a surface comprising:
a core member, the core member having a central axis and a periphery; and
a sheet of material, the sheet of material being comprised of closed-cell silicone foam rubber and having at least a first free end portion;
wherein the sheet of material is attached to the core member with the at least first free end portion extending away from the periphery of the core member such that the material attachment is substantially parallel to the central axis of the core member;
wherein the core member includes a flat surface adjacent the attachment of said sheet of material; wherein the core member and the sheet of material are configured for relative movement with respect to the surface in at least a first direction;
wherein the motion in the first direction causes the at least first free end portion of the sheet of material to contact the surface at a non-zero velocity; and
wherein the motion of the at least first free end portion of the sheet of material produces at least one of the cleaning, buffing and/or polishing action on the surface,
wherein the sheet of material includes a second free end portion and a middle section disposed between the first and second free end portions, and wherein at least a portion of the middle section is attached to the core member and the first and second free end portions extend away from the periphery of the core member,
wherein the middle section of the sheet of material includes first and second portions, and the first portion of the middle section is attached to the core member at a first location and the second portion of the middle section is attached to the core member at a second location, and
wherein a third portion of the middle section of the sheet of material is disposed between the first and second portions, and wherein the third portion extends about a periphery of the core member between the first and second locations.

3. A brush, configured to perform at least one of a cleaning, buffing, and polishing action on a surface comprising:
a core member, the core member having a central axis and a periphery;
a sheet of material, the sheet of material being comprised of closed-cell silicone foam rubber and having at least a first free end portion; and
at least one securement coil, wherein the coil is disposed within a c-channel groove to retain the middle section of the sheet of material within the c-channel groove;
wherein the sheet of material is attached to the core member with the at least first free end portion extending away from the periphery of the core member such that the material attachment is substantially parallel to the central axis of the core member;
wherein the core member includes a flat surface adjacent the attachment of said sheet of material; wherein the core member and the sheet of material are configured for relative movement with respect to the surface in at least a first direction;
wherein the motion in the first direction causes the at least first free end portion of the sheet of material to contact the surface at a non-zero velocity; and
wherein the motion of the at least first free end portion of the sheet of material produces at least one of the cleaning, buffing and/or polishing action on the surface.
