Abstract
A relatively thin, hand-held tool for abrading, sanding or polishing a workpiece comprised of an elongated body constructed to carry a flexible, endless strip longitudinally therebout. The body includes handlike portion and a workpiece engaging portion, which define the path. Means associated with the handle portion are provided to align said strip with respect to the workpiece engaging portion. The body further includes means for releasably holding the strip under tension in contact with the path.
Claims20
A slender, hand-held abrasive tool for abrading planar or contoured surfaces comprising an elongated, generally prismatic, unitary body assembly constructed to carry a removable, flexible endless abrasive strip longitudinally about said body assembly along a generally endless path, said body assembly including:
- a first, relatively long, prismatic main body section, said first body section including a wedge-shaped workpiece engaging portion;
- a second, relatively short body section;
- said first and second body sections being of molded plastic construction with each section having laterally disposed, longitudinally extending side walls for aligning said strip with respect to said workpiece engaging portion, and an end adjacent a corresponding end of the other body section, said body sections being in longitudinal alignment and a side wall of each body section being aligned with a corresponding side wall of the other body section to form a handle portion;
- biasing means for biasing said body sections longitudinally apart;
- and,
- connecting means permanently joining said body sections and said biasing means to form said unitary body assembly, said connecting means allowing limited longitudinal movement between said body sections, wherein said biasing means is operative to releasably hold said strip under tension in non-slipping relationship to said path.
A slender, hand-held tool for abrading, polishing, or sanding a planar or contoured surface comprising an elongated relatively thin prismatic unitary body assembly constructed to carry a removable, flexible endless strip longitudinally about said body assembly along a predetermined path, said body assembly including:
- a first relatively long main body section of molded plastic composition, said first body section including narrow surfaces on opposite sides thereof defining said path, and a surface engaging portion aligned with said narrow surfaces at one end thereof;
- tension means disposed at the other end of said first section operative to releasably hold said strip in tension in contact with said path;
- and,
- locking means permanently connecting said tension means to said main body portion to form said unitary body assembly said locking means allowing limited longitudinal movement between said body section and said tension means;
- said first body section including guides laterally disposed along said narrow surfaces to align said strip with respect to said surface engaging portion, said guides forming a handle portion for gripping said tool.
A slender, hand-held tool for abrading, polishing, or sanding a planar or contoured surface comprising an elongated relatively thin prismatic body assembly constructed to carry a thin, flexible endless abrasive strip longitudinally about said body assembly along a predetermined path, said body assembly including:
- a first relatively long main body section of molded plastic composition, said first body section including narrow surfaces on opposite sides thereof defining said path, a surface engaging portion aligned with said narrow surfaces at one end thereof, and guides laterally disposed along said narrow surfaces to align said strip with respect to said surface engaging portion, the width of said narrow surfaces being less than one (1) inch;
- tension means disposed at the other end of said first section operative to releasably hold said strip in tension in contact with said path;
- and
- means for maintaining said tension means in operative alignment with said body section.
A slender, hand-held tool for abrading, polishing, or sanding a planar or contoured surface comprising an elongated relatively thin prismatic body assembly constructed to carry a removable, flexible endless abrasive strip longitudinally about said body assembly along a predetermined path, said body assembly including:
- a first relatively long main body section of molded plastic composition, said first body section including narrow surfaces on opposite sides thereof defining said path and a surface engaging portion aligned with said narrow surfaces at one end thereof;
- guide means disposed along said narrow surfaces for aligning said strip with respect to said surface engaging portion;
- and
- tension means disposed at the other end of said first section operative to releasably hold said strip in tension in contact with said path;
- said tool being less than nine (9) inches in length and carrying an abrasive strip less than one-half (0.5) inch in width.
A slender, hand-held tool for abrading, polishing, or sanding a planar or contoured surface comprising an elongated relatively thin prismatic body assembly constructed to carry a removable, flexible endless abrasive strip longitudinally about said body assembly along a predetermined path, said body assembly including:
- a first relatively long main body section of molded plastic composition, said first body section including narrow surfaces on opposite sides thereof defining said path and a surface engaging portion aligned with said narrow surfaces at one end thereof;
- guide means disposed along said narrow surfaces for aligning said strip with respect to said surface engaging portion;
- tension means disposed at the other end of said first section operative to releasably hold said strip in tension in contact with said path;
- and
- means for maintaining said tension means in operative alignment with said body section, said tool having an overall length at least 10 times greater than the width of said narrow surfaces.
