Abstract
A drywall sander includes a replaceable sanding pad having a layer of resilient material, and an abrasive surface. The sanding pad includes one or more edge portions that project beyond the edges of a sander head. The edges of the sanding pad can be deformed during use when the sander is used in a corner or the like to thereby prevent scuffing or other damage to adjacent orthogonal surfaces.
Claims20
A sanding member for attachment to a drywall sander of the type having a generally rectangular sanding head with opposite side edges, the sanding member comprising a layer of resilient material with abrasive material disposed on at least a portion of a first side of the resilient material, the replaceable sanding member defining a generally quadrilateral perimeter having end edge portions defining a length, and opposite side edges defining a first width, and wherein the generally quadrilateral perimeter of the replaceable sanding member defines four corner portions, and wherein each corner portion includes a notch forming opposing first edge portions defining a second width that is substantially less than the first width, each notch forming second edge portions that are generally transverse to the opposite side edges of the replaceable sanding member;
- and wherein:
- the replaceable sanding member includes opposite side edge portions that are configured to project beyond side edges of a sanding head of a drywall sander to define resilient wings having a first shape when the resilient wings are not in contact with an object other than a sanding head, the resilient wings deforming to a second shape that is different than the first shape upon contact with an object other than a sanding head.
A replaceable sanding pad for use with drywall sanders of the type having a rectangular head configured to secure sheets of sandpaper thereto, the sanding pad comprising:
- a layer of resilient material defining a first thickness and a generally quadrilateral perimeter, the perimeter having opposite side edges defining a width of at least about 3 7/16 inches and less than about 4 13/16 inches, and end edges defining a length of at least about 9⅞ inches;
- and
- a layer of abrasive material disposed on a first side of the resilient material.
A sanding pad for attachment to a drywall sander head of the type having opposite side edges defining a width, the sanding pad comprising:
- a body portion defining a length and a width, the body portion including a resiliently deformable portion having abrasive material on an outer side thereof to define a sanding surface;
- the body portion including opposite ends configured to wrap around edges of a drywall sander;
- the body portion further defining generally parallel opposite side edges that extend between the opposite ends, the opposite side edges being spaced apart a first width, and wherein the opposite ends define a second width that is substantially less than the dimension.
In a drywall sander of the type that includes a sanding head that is pivotably mounted to a handle, wherein the sanding head defines a generally quadrilateral peripheral edge, and wherein the sanding head is at least somewhat elongated to define a major axis and a minor axis transverse to the major axis, the improvement comprising:
- a resilient pad having an abrasive sanding surface and opposite side portions forming stabilizing means for reducing the tendency of the sanding head to rotate in an unstable manner during side-to-side sanding motion of the sanding head in a direction along the minor axis.
