Flexible and interchangeable multi-head floor polishing disk assembly

Abstract

A disk assembly for use with floor grinding and/or polishing machines. The disk assembly includes multiple cutting heads attached to a flexible rubber disk, and a layer of hook and loop type fastener material for attaching the disk assembly to the drive plate of the floor grinding and/or polishing machine. The disk assembly also includes a foam pad for attachment between the flexible polishing disk and the drive plate to provide additional support structure, and a rigid plate which can optionally be used between the flexible polishing disk and the foam pad to maintain a flat polishing surface.

1 . A disk assembly comprising:
 a flexible disk having opposing faces, an outer diameter and an inner diameter; and   a plurality of separate abrasive heads affixed to one face of the flexible disk.   
     
     
         2 . The disk assembly of  claim 1  further comprising a fastening mechanism affixed to the other face of the flexible disk. 
     
     
         3 . The disk assembly of  claim 2  further comprising a foam backing pad attached to the flexible disk by the fastening mechanism. 
     
     
         4 . The disk assembly of  claim 2  further comprising a rigid metal backing plate attached to the flexible disk by the fastening mechanism. 
     
     
         5 . The disk assembly of  claim 4  further comprising a foam backing pad attached to the rigid metal backing plate. 
     
     
         6 . The disk assembly of  claim 2  wherein the fastening mechanism is a layer of loop-type fastener material. 
     
     
         7 . The disk assembly of  claim 1  wherein the abrasive heads are diamond-impregnated abrasive heads. 
     
     
         8 . The disk assembly of  claim 1  wherein the flexible disk is rubber. 
     
     
         9 . The disk assembly of  claim 1  wherein the abrasive heads are permanently affixed to the flexible disk. 
     
     
         10 . The disk assembly of  claim 9  wherein the abrasive heads are glued to the flexible disk. 
     
     
         11 . The disk assembly of  claim 1  wherein the abrasive heads are detachably affixed to the flexible disk. 
     
     
         12 . The disk assembly of  claim 11  wherein the abrasive heads are affixed to the flexible disk by a hook and loop material. 
     
     
         13 . The disk assembly of  claim 1  wherein the plurality of abrasive heads includes a first group of abrasive heads arranged substantially along the outer diameter of the flexible disk, and a second group of abrasive heads arranged substantially along the inner diameter of the flexible disk. 
     
     
         14 . The disk assembly of  claim 13  wherein the first and second groups of cutting heads alternate in circumferential position around the flexible disk. 
     
     
         15 . The disk assembly of  claim 1  wherein the abrasive heads are round. 
     
     
         16 . The disk assembly according to  claim 1  wherein the disk assembly is suitable for a burnishing machine. 
     
     
         17 . A disk assembly for grinding and/or polishing floors, comprising:
 a rubber disk having opposing faces, an outer diameter and an inner diameter;   a plurality of separate and round diamond-impregnated abrasive heads rigidly affixed to one face of the rubber disk; and   a foam backing pad attached to the other face of the rubber disk by a layer of hook and loop type fastener material.   
     
     
         18 . The disk assembly of  claim 17  wherein the plurality of abrasive heads includes a first group of cutting heads arranged substantially along the outer diameter of the rubber disk, and a second group of abrasive heads arranged substantially along the inner diameter of the rubber disk. 
     
     
         19 . The disk assembly of  claim 18  wherein the first and second group of abrasive heads alternate in circumferential position around the rubber disk. 
     
     
         20 . The disk assembly according to  claim 17  wherein the disk assembly is suitable for a burnishing machine.
