Embodiment Construction

[0014] Referring now to the drawings, wherein like reference numerals indicate like or corresponding parts throughout the several views, figure 1 and 2 A hand-held, manually operated sanding tool or block 2 is shown for use with a flexible replaceable sheet abrasive 40 . The term "manually operated" refers to the fact that the tool 2 is not an electric tool. That is, all power to the tool is provided by the user and the tool itself does not include a motor. The term "abrasive sheet" refers to a thin, flexible, generally square or rectangular sheet of abrasive material having discrete ends attachable to an abrasive block. Such sheet abrasives include, for example, conventional sandpaper, soft abrasive scrims, nonwoven abrasives (such as Scotch-brite available from 3M Company, St. Paul, MN). TM , and thin, flexible abrasive sheet materials such as those described in US Patent No. 6,613,113 (Minick et al.), the entire contents of which are incorporated herein by reference. Th...

Abstract

A hand-held, manually-operated, sanding tool for use with a replaceable sheet-like abrasive material, such as sandpaper, includes a base member, a molded interface pad provided on the base member to define a working face against which the sheet-like abrasive material is arranged, and a retaining mechanism arranged to maintain the sheet-like abrasive material in operative relation with the interface pad. The base member is formed of a first material and the molded interface pad is formed of a second injection moldable material.

Description

Background technique [0001] The present invention generally relates to a hand-held, hand-operated sanding tool that uses a sheet-like abrasive such as sandpaper. [0002] Manually operated hand-held sanding tools, such as abrasive blocks, are often used with abrasive sheets, such as traditional sandpaper, to hand sand or polish a work surface. One commercially available abrasive block is the 3M Grinding Block available from 3M Company (St. Paul, MN). TM Rubber grinding blocks. The hand sanding tool may include a foam interface pad adhesively bonded to the working surface of the sanding tool. However, such interface pads have one or more drawbacks or disadvantages. It would be desirable to provide a hand-held, manually operated sanding tool that includes an interface pad that overcomes the deficiencies and disadvantages of sanding tools having adhesively bonded foam interface pads. Contents of the invention [0003] The present invention provides a hand-held, hand-operate...
