Abstract
An adjustable sander pad assembly comprising a backer flange, multiple support fingers, multiple adjustment supports, a sander plate, and an adjustment ring; wherein the multiple support fingers each has a first and a second attachment point, wherein the first attachment point is attached to the adjustment support, wherein the second attachment point is attached to the adjustment ring, wherein the support fingers, the adjustment supports, the sander plate, and the adjustment ring are mounted on the backer flange, and wherein the adjustment ring is rotated to move the support fingers and adjustment supports radially from a retracted position to an extended position.
Claims9
An adjustable sander pad assembly for a rotary floor sander providing a stiff sander pad position and a flexible sander pad position for sanding surfaces comprising;
- a flex plate;
- a sander plate fixedly mounted on the flex plate and
- a backer flange fixedly mounted on the sander plate;
- multiple support fingers having a finger thickness, multiple adjustment supports and
- an adjustment ring moveably mounted together and positioned between the flex plate and the backer flange;
- wherein the multiple support fingers are elongated and narrow, and have a first and a second attachment point at each respective end;
- wherein the first attachment point is movably attached to an adjustment support;
- wherein the second attachment point is movably attached to the adjustment ring;
- wherein the backer flange is circular with a center opening and a radius;
- wherein the backer flange has radial channels;
- wherein the length of the radial channels is from about half to more than half of the radius of the backer flange;
- wherein the backer flange has guide mounts having a guide mount thickness;
- wherein the sander plate is fixedly attached to the guide mounts creating a finger space in which the support fingers move;
- wherein the multiple adjustment supports have a plurality of radial projections;
- wherein the radial projections are movably engaged with the radial channels;
- wherein the adjustment ring can be rotated to move the support fingers;
- wherein the adjustment supports are moved radially by the support fingers from a retracted position to an extended position and back;
- and
- wherein when operating the rotary sander in the extended position the sander pad assembly is more rigid and wherein when operating the rotary sander in the retracted position the sander pad assembly is more flexible for sanding surfaces.
