Embodiment Construction

[0019] FIG. 1 shows one embodiment of a handheld hand-controlled sanding tool or sanding pad 10 . The term "manually controlled" means that the tool 10 is not a power tool. That is, all power for tool 10 is provided by the user (not shown), and tool 10 itself does not include a motor. It should be appreciated, however, that the principles of the present invention may be applied to power tools and are not necessarily limited to hand-operated sanding tools.

[0020] The sanding tool 10 is described below, which may be used with abrasive flakes. The terms "abrasive sheet" and "abrasive sheet" are used interchangeably throughout this specification and both refer to a thin, flexible, generally square or rectangular abrasive sheet having discrete ends that can be attached to a sanding pad (or edge). Such abrasive sheets include, for example, conventional sandpaper, flexible abrasive scrims, nonwoven abrasives such as Scotch-Brite® available from 3M Company (St. Paul, MN). TM ) a...

Abstract

A hand-held, manually-operated sanding tool for use with a replaceable sheet of abrasive material includes a base member and a clamping mechanism. The base member defines first and second ends, a bottom surface extending between the first and second ends, a contact surface formed opposite the bottom surface and extending from the first end, and at least one tooth extending from the contact surface. The clamping mechanism is pivotally connected to the base member at a pivot point, defines a front section opposite the pivot point, and is movable about the pivot point between an open position, in which the front section is spaced from the contact surface for receiving an end portion of a sheet of abrasive material, and a closed position, in which the clamping mechanism is more proximate the contact surface and the front section is more proximate the at least one tooth.
