Benefits of technology

[0010]An object of the invention is to provide a flexible, and in certain embodiments a resilient, article and method of manufacturing sa

Problems solved by technology

Difficulties may arise if the abrasive article does not provide necessary and sufficient ergonomic accommodations.
Such an arrangement, however, results in premature degradation of the sheet like substrate due to the forces experienced during use.
Wherein sanding sponges are in a sheet like form having only one side coated with abrasive particles, a problem exists in that the opposite side of the sanding sponge which is gripped by the hand may be sli

Embodiment Construction

[0109]While the invention is amenable to various modifications and alternative forms, specifics thereof are shown by way of example in the drawings and described in detail herein. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

[0110]FIG. 1 illustrates a tool comprising a sanding sponge 10 having vacuum channels 14 in a grid form recessed into the large flat surface 15 or surfaces of the sanding sponge. The sponge 10 is of a type known to the skilled artisan and is commonly used for sanding wood or drywall. The sponge is typically made of a resilient material such as urethane foam or foam rubber or sponge but should not be limited to only these materials and should include all materials having a resilience including, e.g., rubber and plastic. The sponge has an abras...

Abstract

The present invention provides a resilient hand-held abrasive article comprising a flexible and/or conformable grip comprising a top surface, a bottom surface and individual small high-grip pads attached to each other in a pattern that leaves voids therebetween, the individual small high-grip pads comprising a top and a bottom. The top surface of a sanding article is attached, and in certain embodiments removably attached, to the bottom of the high-grip pads and a bottom surface having abrasive particles coated thereon. In certain embodiments, the flexible and/or conformable grip may not comprise voids.

Description

RELATED APPLICATIONS[0001]This application claims benefit to provisional application Ser. No. 60 / 903,984 filed on Feb. 28, 2007 which is hereby incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to abrasive articles for abrading a work surface and, more particularly, to resilient abrasive articles.[0004]2. Description of the Related Art[0005]Hand-held abrasive articles are used in a variety of sanding operations. The user generally holds the abrasive article in his or her hand, moving the abrasive article across the surface to be sanded. Difficulties may arise if the abrasive article does not provide necessary and sufficient ergonomic accommodations.[0006]U.S. Pat. No. 6,613,113 to Minick discloses a flexible abrasive product comprising a flexible sheet-like substrate comprising a multiplicity of separated resilient bodies connected to each other in a generally planar array in a pattern that ...
