Abstract
The present invention relates to a hand-held abrasive article. In one embodiment, the hand-held abrasive article includes an elongated resilient body having a perpendicular cross-sectional surface. The cross-sectional surface of the resilient body includes at least one internal right angle, at least one internal acute angle, at least one internal obtuse angle, and at least one curved portion. At least a portion of the resilient body is coated with abrasive.
Description
- The present invention relates to resilient flexible abrasive devices typically referred to as sanding sponges, and more particularly, to a hand-held, disposable abrasive article for sanding a variety of surface shapes and configurations.
- Common sanding tasks calling for considerable detail work or access to small confined areas, or for sanding contoured surfaces, often require that the surfaces be hand sanded. Hand-held sanding devices for this purpose have essentially consisted of a sanding block for holding conventional sandpaper wrapped over the block. By using a sanding block as a sandpaper holder, hand-applied sanding forces on the sandpaper can be increased and more evenly distributed.
- The difficulty with the above-mentioned prior sanding devices is the necessity of installing or wrapping a separate piece of sandpaper around the device. This installation or wrapping process presents some inconvenience to the user. For example, if the paper is improperly installed, it is susceptible to falling off. Also, the device requires the purchase of separate sheets of sandpaper that is a further inconvenience in terms of the amount of supplies needed.
- U.S. Pat. No. 4,887,396 (Lukianoff) discloses a hand-sized sanding device that eliminates the need for a separate sheet of sandpaper. The sanding device is provided with its own integral abrasive surfaces that can be manufactured at a sufficiently low cost to be disposable. The sanding device of Lukianoff can be conveniently used to hand sand a variety of standard, contoured, or shaped surfaces, such as trim or molding surfaces, and for projecting into exactly defined areas.
- Another type of sanding device is the resilient flexible sanding sponge. Sanding sponges generally include a layer of abrasive particles adhered to a foam body by a flexible adhesive. One such sanding sponge is the 3M Small Area Sanding Sponge available from 3M, St. Paul, Minn. Typically, a user places the body against the palm of his or her hand and rubs the abrasive over a surface to be abraded. The flexible adhesive layer and the foam body permit the layer of abrasive to conform to the surface being abraded.
- While such sanding sponges work well to abrade objects having flat surfaces these sponges are not well suited to sand a variety of contoured surfaces because the foam body and/or the layer of flexible adhesive is too stiff to conform to the contoured surface being abraded. A sanding sponge with high tear strength body layer is disclosed in U.S. Pat. No. 6,419,573 (Lise et al.).
- Sanding sponges often only have a projecting right angle to sand perpendicular corners, and typically do not have a variety of projecting angles and curves. It may be necessary to sand surfaces that have contours other than a perpendicular corner. Especially when sanding millwork, it is often necessary to sand a variety of contoured surfaces.
- The present invention relates to a hand-held abrasive article. In one embodiment, the hand-held abrasive article includes an elongated resilient body having a perpendicular cross-sectional surface. The cross-sectional surface of the resilient body includes at least one internal right angle, at least one internal acute angle, at least one internal obtuse angle, and at least one curved portion. At least a portion of the resilient body is coated with an abrasive.
- In another embodiment, the hand-held abrasive article includes an elongated resilient body having a first end surface and a second end surface. The hand-held abrasive article further includes a first planar major surface, a second planar major surface contiguous with the first planar major surface, a third planar major surface contiguous with the second planar major surface, a fourth planar major surface contiguous with the third planar major surface, and a curved surface contiguous with the fourth planar major surface and the first planar major surface. Each major surface and the curved surface extend between the first end surface and second end surface. At least one of the first planar major surface, second planar major surface, third planar major surface, fourth planar major surface, or curved surface is abrasive.
- In another embodiment, the hand-held abrasive article includes a resilient body having a first end surface and a second end surface. The hand-held abrasive article further includes a first planar major surface, a second planar major surface, a third planar major surface, a fourth planar major surface, and a curved surface. Each major surface and the curved surface extend between the first end surface and second end surface. The intersection of two of the planar major surfaces form an acute angle, the intersection of two of the planar major surfaces form an obtuse angle, and the intersection of two of the planar major surfaces form a right angle. At least one of the first planar major surface, second planar major surface, third planar major surface, fourth planar major surface, or curved surface is covered with an abrasive material.

Theabrasive particles 26 may be adhered to only a portion of thebody 22, or theabrasive particles 26 may be adhered to theentire body 22. - The flexible adhesive 24 bonds the layer of
abrasive particles 26 to thebody 22 and adheres theabrasive particles 26 together while being sufficiently flexible to conform with thebody 22 to the contour of the surface to be abraded by the sandingsponge 20.
