Abstract

A tool for moving an abrasive media. The tool includes a tool body, a platen, a drive system and a retaining knob. The platen has an exterior platen surface and a knob aperture that is formed through the exterior platen surface. The drive system is housed in the tool body and configured to move the platen. The drive system includes an output member with a first threaded portion. The retaining knob is received through the knob aperture in the exterior platen surface of the platen. The retaining knob has a knob portion, which has an exterior surface, and an attachment member with a second threaded portion that is threadably coupled to the first threaded portion. The platen surface and at least a portion of the knob surface are co-planar. A related method is also provided.

Claims

1. A tool for moving an abrasive media, the tool comprising:

a tool body;

a platen having an exterior platen surface and a knob aperture that is formed through the exterior platen surface;

a drive system housed in the tool body and configured to move the platen, the drive system including an output member with a first threaded portion; and

a retaining knob that is received through the knob aperture in the exterior platen surface of the platen, the retaining knob having a knob portion and an attachment member, the knob portion having an exterior knob surface, the attachment member having a second threaded portion that is threadably coupled to the first threaded portion;

wherein the platen surface and at least a portion of the knob surface are co-planar, and

wherein at least one of a hook fastener and a loop fastener of a hook-and-loop fastener system is applied to the platen surface and the at least the portion of the knob surface.

8. The tool of claim 1, wherein the exterior surface of the platen is disposed in a flat plane.

2. A tool for moving an abrasive media, the tool comprising:

a tool body;

a platen having an exterior platen surface and a knob aperture that is formed through the exterior platen surface;

a drive system housed in the tool body and configured to move the platen, the drive system including an output member with a first threaded portion; and

a retaining knob that is received through the knob aperture in the exterior platen surface of the platen, the retaining knob having a knob portion and an attachment member, the knob portion having an exterior knob surface, the attachment member having a second threaded portion that is threadably coupled to the first threaded portion;

wherein the platen surface and at least a portion of the knob surface are co-planar,

wherein a plurality of dust extraction holes are formed through the platen, and

wherein the knob aperture includes a counterbore and a through-hole, wherein at least one of the first threaded portion and the second threaded portion is received through the through-hole and wherein the dust extraction holes are formed in the counterbore.

3. The tool of claim 2, wherein the dust extraction holes are disposed concentrically about the through-hole.

4. The tool of claim 2, wherein the knob portion includes exterior manual gripping surface.

12. The tool of claim 2, wherein the exterior surface of the platen is disposed in a flat plane.

5. A tool for moving an abrasive media, the tool comprising:

a tool body;

a platen having an exterior platen surface and a knob aperture that is formed through the exterior platen surface;

a drive system housed in the tool body and configured to move the platen, the drive system including an output member with a first threaded portion; and

a retaining knob that is received through the knob aperture in the exterior platen surface of the platen, the retaining knob having a knob portion and an attachment member, the knob portion having an exterior knob surface, the attachment member having a second threaded portion that is threadably coupled to the first threaded portion;

wherein the platen surface and at least a portion of the knob surface are co-planar, and

wherein the retaining knob further includes a handle that is movably coupled to the knob portion.

6. The tool of claim 5, wherein the knob aperture includes a counterbore and a through-hole, wherein at least one of the first threaded portion and the second threaded portion is received through the through-hole and wherein the handle is movable into a position where it is stored in the counterbore.

7. The tool of claim 5, wherein the handle comprises a wire clip that is pivotally coupled to the knob portion.

13. The tool of claim 5, wherein the exterior surface of the platen is disposed in a flat plane.

9. A method comprising:

providing a tool with a tool body and a drive system, the drive system having an output member;

mounting a platen to the output member;

installing a retaining knob into a knob aperture in the platen; and

tightening the retaining knob to the output member such that an exterior surface of the platen is co-planar with at least a portion of the retaining knob;

coupling an abrasive media to the exterior surface of the platen,

wherein the abrasive media is coupled to the platen via a hook-and-loop fastener system, and

wherein at least one of a hook fastener and a loop fastener is disposed on the exterior surface of the retaining knob.

10. A method comprising:

providing a tool with a tool body and a drive system, the drive system having an output member;
