ABSTRACT:
A hand-held sander includes a body formed of a flexible cellular polyester polurethane foam, molded in place with a working surface of either plastic coated fabric (for use with adhesive-backed abrasives) or the `hook` portion of a "hook and loop" type gripping system, for holding woven or non-woven materials in place. The body includes a handle, leading ends extending from the handle of differing lengths, thicknesses and rates of flexural resistance. One leading end includes a radius edge while the other leading end forms an acute angle edge. These design features permit a broad range of forces to be exerted upon the work by the user via its working surface, in the preparation and/or finishing of the surface(s) of many materials; the adaptability of its working surface to a wide range of surface configurations and compound radii; improved accessibility to confined or restricted areas; the exertion and spread (or conatainment) of a range of localized pressure forces by digital (thumb and/or fingertip(s')) control; a stabilized zone for flat sanding; and, finally a means for applying a blend of forces along an extended path of differing, yet parallel, work planes.
