Abstract
A hand-held sanding device for sanding a work piece. The sanding device includes a frame adapted for a manual grip and a sanding material provided within the frame for movement relative to the frame. The sanding material forms a sanding surface for the device. The sanding material moves relative to the frame through contact between the sanding surface and the work piece.

A hand-held sanding device for sanding a work piece, the device comprising:
- a frame adapted for a manual grip and permitting application of a manual pulling force across a workpiece;
- rollers coupled to the frame;
- a sanding material provided within and coupled to the rollers and frame for movement with the frame when the rollers are not permitted to roll, and movement relative to the frame when the rollers are permitted to roll, the sanding material forming a sanding surface for the device in frictional contact with a workpiece, and creating a secondary pulling force on the sanding material relative to the frame by application of said manual pulling force;
- and
- a mechanism which permits rolling of the rollers and permits movement of the sanding material relative to the frame in a first direction in response to said secondary pulling force, and restricts rolling of the rollers and restricts movement of the sanding material relative to the frame in a direction opposite to the first direction.

A hand-held sanding device comprising:
- a frame including a manual grip permitting application of a manual pulling force across a workpiece;
- a plurality of rollers mounted within the frame, one or more of the rollers coupled to the frame via a mechanism which permits rotation of a roller in a first direction and restricts rotation of the roller in a second direction opposite the first direction;
- a sanding belt trained over the rollers to rotate with the rollers during a sanding operation, and creating a secondary force on the sanding belt and rollers by application of said manual pulling force, the mechanism coupling the frame and rollers permitting said rotation of a roller in said first direction response to said secondary force;
- and
- a tensioning member for maintaining tension in the sanding belt as the belt rotates with the rollers, the tensioned belt forming a planar sanding surface for the device.
